Conservation status
–
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Various systems of conservation status exist and are in use at international, multi-country, the IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Also included are species that have gone extinct since 500 AD, when discussing the IUCN Red List, the official term threatened is a grouping of three categories, critically endangered, endangered, and vulnerable. Widespread and abundant taxa are included in this category, Data deficient – Not enough data to make an assessment of its risk of extinction Not evaluated – Has not yet been evaluated against the criteria. The Convention on International Trade in Endangered Species of Wild Fauna and Flora aims to ensure that trade in specimens of wild animals. Many countries require CITES permits when importing plants and animals listed on CITES, in the European Union, the Birds and Habitats Directives are the legal instruments that evaluate the conservation status within the EU of species and habitats. NatureServe conservation status focuses on Latin America, United States, Canada, and it has been developed by scientists from NatureServe, The Nature Conservancy, and the network of natural heritage programs and data centers. It is increasingly integrated with the IUCN Red List system and its categories for species include, presumed extinct, possibly extinct, critically imperiled, imperiled, vulnerable, apparently secure, and secure. The system also allows ambiguous or uncertain ranks including inexact numeric ranks, NatureServe adds a qualifier for captive or cultivated only, which has a similar meaning to the IUCN Red List extinct in the wild status. The Red Data Book of the Russian Federation is used within the Russian Federation, in Australia, the Environment Protection and Biodiversity Conservation Act 1999 describes lists of threatened species, ecological communities and threatening processes. The categories resemble those of the 1994 IUCN Red List Categories & Criteria, prior to the EPBC Act, a simpler classification system was used by the Endangered Species Protection Act 1992. Some state and territory governments also have their own systems for conservation status, in Belgium, the Flemish Research Institute for Nature and Forest publishes an online set of more than 150 nature indicators in Dutch. In Canada, the Committee on the Status of Endangered Wildlife in Canada is a group of experts that assesses and designates which wild species are in danger of disappearing from Canada. Under the Species at Risk Act, it is up to the federal government, in China, the State, provinces and some counties have determined their key protected wildlife species. There is the China red data book, in Finland, a large number of species are protected under the Nature Conservation Act, and through the EU Habitats Directive and EU Birds Directive. In Germany, the Federal Agency for Nature Conservation publishes red lists of endangered species, india has the Wild Life Protection Act,1972, Amended 2003 and the Biological Diversity Act,2002. In Japan, the Ministry of Environment publishes a Threatened Wildlife of Japan Red Data Book, in the Netherlands, the Dutch Ministry of Agriculture, Nature and Food Quality publishes a list of threatened species, and conservation is enforced by the Nature Conservation Act 1998. Species are also protected through the Wild Birds and Habitats Directives, in New Zealand, the Department of Conservation publishes the New Zealand Threat Classification System lists

Least Concern
–
A least concern species is one which has been categorized by the International Union for Conservation of Nature as evaluated but not qualified for any other category. As such they do not qualify as threatened, near threatened, species cannot be assigned the Least Concern category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, since 2001 the category has had the abbreviation LC, following the IUCN2001 Categories & Criteria. However, around 20% of least concern taxa in the IUCN database use the code LR/lc, prior to 2001 least concern was a subcategory of the Lower Risk category and assigned the code LR/lc or. While least concern is not considered a red listed category by the IUCN, the number of animal species listed in this category totals 14033. There are also 101 animal subspecies listed and 1500 plant taxa, there are also two animal subpopulations listed, the Australasian and Southern African subpopulations of spiny dogfish. No fungi or protista have the classification, though only four species in those kingdoms have been evaluated by the IUCN, humans qualify for this category, and in 2008 were formally assessed as such by the IUCN

IUCN Red List
–
The IUCN Red List of Threatened Species, founded in 1964, is the worlds most comprehensive inventory of the global conservation status of biological species. The International Union for Conservation of Nature is the main authority on the conservation status of species. A series of Regional Red Lists are produced by countries or organizations, the IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world, the aim is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to try to reduce species extinction. Major species assessors include BirdLife International, the Institute of Zoology, the World Conservation Monitoring Centre, collectively, assessments by these organizations and groups account for nearly half the species on the Red List. The IUCN aims to have the category of every species re-evaluated every five years if possible, the 1964 IUCN Red List of Threatened Plants used the older pre-criteria Red List assessment system. Plants listed may not, therefore, appear in the current Red List, IUCN advise that is best to check both the online Red List and the 1997 plants Red List publication. The 2006 Red List, released on 4 May 2006 evaluated 40,168 species as a whole, plus an additional 2,160 subspecies, varieties, aquatic stocks, on 12 September 2007, the World Conservation Union released the 2007 IUCN Red List of Threatened Species. Russ Mittermeier, chief of Swiss-based IUCNs Primate Specialist Group, stated that 16,306 species are endangered with extinction,188 more than in 2006, the Red List includes the Sumatran orangutan in the Critically Endangered category and the Bornean orangutan in the Endangered category. The study shows at least 1,141 of the 5,487 mammals on Earth are known to be threatened with extinction, and 836 are listed as Data Deficient. The Red List of 2012 was released 19 July 2012 at Rio+20 Earth Summit, nearly 2,000 species were added, the IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction. With 3,947 described as endangered and 5,766 as endangered. At threat are 41% of amphibian species, 33% of reef-building corals, 30% of conifers, 25% of mammals, the IUCN Red List has listed 132 species of plants and animals from India as Critically Endangered. Extinct – No known individuals remaining, extinct in the wild – Known only to survive in captivity, or as a naturalized population outside its historic range. Critically endangered – Extremely high risk of extinction in the wild, Endangered – High risk of extinction in the wild. Vulnerable – High risk of endangerment in the wild, near threatened – Likely to become endangered in the near future. Does not qualify for a more at-risk category, widespread and abundant taxa are included in this category. Data deficient – Not enough data to make an assessment of its risk of extinction, Not evaluated – Has not yet been evaluated against the criteria

Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Plant
–
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is generally limited to the green plants, which form an unranked clade Viridiplantae. This includes the plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts and their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although reproduction is also common. There are about 300–315 thousand species of plants, of which the great majority, green plants provide most of the worlds molecular oxygen and are the basis of most of Earths ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankinds basic foodstuffs, Plants play many roles in culture. They are used as ornaments and, until recently and in variety, they have served as the source of most medicines. The scientific study of plants is known as botany, a branch of biology, Plants are one of the two groups into which all living things were traditionally divided, the other is animals. The division goes back at least as far as Aristotle, who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus created the basis of the system of scientific classification. Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, however, these organisms are still often considered plants, particularly in popular contexts. When the name Plantae or plant is applied to a group of organisms or taxon. The evolutionary history of plants is not yet settled. Those which have been called plants are in bold, the way in which the groups of green algae are combined and named varies considerably between authors. Algae comprise several different groups of organisms which produce energy through photosynthesis, most conspicuous among the algae are the seaweeds, multicellular algae that may roughly resemble land plants, but are classified among the brown, red and green algae. Each of these groups also includes various microscopic and single-celled organisms

Flowering plant
–
The flowering plants, also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c.295,383 known species, etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term angiosperm comes from the Greek composite word meaning enclosed seeds, the ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago, and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, angiosperms differ from other seed plants in several ways, described in the table. These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants, the amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms. The vascular bundles of the stem are arranged such that the xylem and phloem form concentric rings, in the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium, the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Among the monocotyledons, the bundles are more numerous in the stem and are scattered through the ground tissue. They contain no cambium and once formed the stem increases in diameter only in exceptional cases, the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, and provide the most trustworthy external characteristics for establishing relationships among angiosperm species, the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally on a shoot or from the axil of a leaf, occasionally, as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. There are two kinds of cells produced by flowers. Microspores, which divide to become pollen grains, are the male cells and are borne in the stamens. The female cells called megaspores, which divide to become the egg cell, are contained in the ovule. The flower may consist only of parts, as in willow. Usually, other structures are present and serve to protect the sporophylls, the individual members of these surrounding structures are known as sepals and petals. The outer series is usually green and leaf-like, and functions to protect the rest of the flower, the inner series is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators, attraction is effected by color, scent, and nectar, which may be secreted in some part of the flower

Eudicots
–
The eudicots, Eudicotidae or eudicotyledons are a monophyletic clade of flowering plants that had been called tricolpates or non-magnoliid dicots by previous authors. The close relationships among flowering plants with tricolpate pollen grains was initially seen in studies of shared derived characters. These plants have a trait in their pollen grains of exhibiting three colpi or grooves paralleling the polar axis. Later molecular evidence confirmed the basis for the evolutionary relationships among flowering plants with tricolpate pollen grains. The term means true dicotyledons, as it contains the majority of plants that have been considered dicots and have characteristics of the dicots, the term eudicots has subsequently been widely adopted in botany to refer to one of the two largest clades of angiosperms, monocots being the other. The remaining angiosperms are sometimes referred to as basal angiosperms or paleodicots, the other name for the eudicots is tricolpates, a name which refers to the grooved structure of the pollen. Members of the group have tricolpate pollen, or forms derived from it and these pollens have three or more pores set in furrows called colpi. In contrast, most of the seed plants produce monosulcate pollen. The name tricolpates is preferred by some botanists to avoid confusion with the dicots, numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Most leafy trees of midlatitudes also belong to eudicots, with exceptions being magnolias and tulip trees which belong to magnoliids, and Ginkgo biloba. The name eudicots is used in the APG system, of 1998 and it is applied to a clade, a monophyletic group, which includes most of the dicots. The eudicots can be divided into two groups, the basal eudicots and the core eudicots, basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group, a 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots

Rosids
–
The rosids are members of a large clade of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification and these orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period, molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. The name is based upon the name Rosidae, which had usually been understood to be a subclass, in 1967, Armen Takhtajan showed that the correct basis for the name Rosidae is a description of a group of plants published in 1830 by Friedrich Gottlieb Bartling. The clade was later renamed Rosidae and has been variously delimited by different authors, the name rosids is informal and not assumed to have any particular taxonomic rank like the names authorized by the ICBN. The rosids are monophyletic based upon evidence found by molecular phylogenetic analysis, three different definitions of the rosids were used. Some authors included the orders Saxifragales and Vitales in the rosids, others excluded both of these orders. The circumscription used in this article is that of the APG IV classification, which includes Vitales, the rosids and Saxifragales form the superrosids clade. This is one of three groups compose the Pentapetalae, the others being Dilleniales and the superasterids. The rosids consist of two groups, the order Vitales and the eurosids, the eurosids, in turn, are divided into two groups, fabids and malvids. The rosids consist of 17 orders, in addition to Vitales, there are 8 orders in fabids and 8 orders in malvids. Some of the orders have only recently been recognized and these are Vitales, Zygophyllales, Crossosomatales, Picramniales, and Huerteales. The phylogeny of Rosids shown below is adapted from the Angiosperm Phylogeny Group website, the nitrogen-fixing clade contains a high number of actinorhizal plants. Not all plants in this clade are actinorhizal, however, media related to Rosids at Wikimedia Commons

Celastrales
–
The Celastrales are an order of flowering plants found throughout the tropics and subtropics, with only a few species extending far into the temperate regions. The 1200 to 1350 species are in about 100 genera, all but seven of these genera are in the large family Celastraceae. Until recently, the composition of the order and its division into families varied greatly from one author to another, the Celastrales are a diverse order that has no conspicuous distinguishing characteristic, so is consequently hard to recognize. The flowers are small with a conspicuous nectary disk. The stipules are small or rarely absent, the micropyle has two openings and is therefore called a bistomal micropyle. Flowers with well-developed male and female parts are often functionally unisexual, the seed often has an aril. In bud, the sepals have a quincuncial arrangement and this means that two sepals are inside, two are outside, and the remaining sepal is half inside and half outside. Perhaps the most conspicuous and unusual trait of the Celastrales is the nectary disk, since the orders are not closely related, the disk must have been an independent development in each of these lines. The Celastrales are a member of the Celastrales, Oxalidales, and Malpighiales clade. of Fabidae, the name Celastrales was first used by Thomas Baskerville in 1839. The family Celastraceae was the group consistently placed in the order by all authors who accepted it. Because of the ambiguity and complexity of its definition, the Celastraceae became a ground for genera of dubious affinity. Several genera were assigned to family with considerable doubt about whether they really belonged there. Also, some genera that belong in the Celastraceae were placed elsewhere. By the end of the 20th century, Goupia and Forsellesia had been excluded from the Celastraceae, Goupia is now in the Malpighiales. Forsellesia is now in the Crossosomatales and it continues to be the subject of a dispute about whether its proper name is Forsellesia or Glossopetalon. After being placed elsewhere, Canotia, Brexia, and Plagiopteron were found to belong in the Celastraceae, the family Hippocrateaceae was found to be deeply nested within the Celastraceae and is no longer recognized as a separate family. In 2000, Vincent Savolainen et alii found that three families - Lepidobotryaceae, Parnassiaceae, and Celastraceae - were closely related, Savolainen and co-authors also excluded Lophopyxis from the Celastrales. Lophopyxis now constitutes a family in the Malpighiales

Binomial nomenclature
–
Such a name is called a binomial name, a binomen, binominal name or a scientific name, more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs, for example, humans belong to the genus Homo and within this genus to the species Homo sapiens. The formal introduction of system of naming species is credited to Carl Linnaeus. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici many names of genera that were adopted by Linnaeus. Although the general principles underlying binomial nomenclature are common to these two codes, there are differences, both in the terminology they use and in their precise rules. Similarly, both parts are italicized when a binomial name occurs in normal text, thus the binomial name of the annual phlox is now written as Phlox drummondii. In scientific works, the authority for a name is usually given, at least when it is first mentioned. In zoology Patella vulgata Linnaeus,1758, the original name given by Linnaeus was Fringilla domestica, the parentheses indicate that the species is now considered to belong in a different genus. The ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, in botany Amaranthus retroflexus L. – L. is the standard abbreviation used in botany for Linnaeus. – Linnaeus first named this bluebell species Scilla italica, Rothmaler transferred it to the genus Hyacinthoides, the ICN does not require that the dates of either publication be specified. Prior to the adoption of the binomial system of naming species. Together they formed a system of polynomial nomenclature and these names had two separate functions. First, to designate or label the species, and second, to be a diagnosis or description, such polynomial names may sometimes look like binomials, but are significantly different. For example, Gerards herbal describes various kinds of spiderwort, The first is called Phalangium ramosum, Branched Spiderwort, is aptly termed Phalangium Ephemerum Virginianum, Soon-Fading Spiderwort of Virginia. The Latin phrases are short descriptions, rather than identifying labels, the Bauhins, in particular Caspar Bauhin, took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words. The adoption by biologists of a system of binomial nomenclature is due to Swedish botanist and physician Carl von Linné. It was in his 1753 Species Plantarum that he first began using a one-word trivial name together with a generic name in a system of binomial nomenclature. This trivial name is what is now known as an epithet or specific name

Martin Henrichsen Vahl was a Danish-Norwegian botanist, herbalist and zoologist. Martin Vahl was born in Bergen, Norway and attended Bergen Cathedral School and he studied botany at the University of Copenhagen and at Uppsala University under Carolus Linnaeus. XVI-XXI, Symbolæ Botanicæ I-III, Eclogæ Americanæ I-IV and Enumeratio Plantarum I-II and he lectured at the University of Copenhagen Botanical Garden from 1779 to 1782. Vahl made several trips in Europe and North Africa between 1783 and 1788. He became professor at the Society for Natural History at the University of Copenhagen in 1786 and was a professor of botany from 1801 to his death. In 1792, he was elected a member of the Royal Swedish Academy of Sciences. He died in Copenhagen, Denmark at age 55 and his son Jens Vahl also became a botanist.

Stephan Endlicher
–
Endlicher István László was an Austrian botanist, numismatist and Sinologist. He was a director of the Botanical Garden of Vienna and he was born in Pressburg and died in Vienna. Endlicher studied theology and received minor orders, in 1828 he was appointed to the Austrian National Library to reorganize its manuscript collection. Concurrently he studied history, in particular botany, and East-Asian languages. In 1836 Endlicher was appointed keeper of the cabinet of natural history. He wrote a description of the plant kingdom according to a natural system. As proposed by Endlicher, it contained images with text and it was published together with the reissue of Franz Ungers Grundzüge der Botanik. As a known liberal, Endlicher was asked to act as mediator during the revolution of 1848, in 1848 he also became a member of the Frankfurt Parliament and the assembly at Kremsier. His linguistic publications comprise Analecta Grammatica, and Anfangsgründe der chinesischen Grammatik, the majority and the most valuable of his works are on botany. The principal of his botanical works are, Ceratotheca, Flora Posoniensis, Diesingia, Atacta Botanica, Iconographia Generum Plantarum, Enchiridium Botanicum. Endlicher established the botanical journal Annalen des Wiener Museums der Naturgeschichte and he began the work Flora Brasiliensis with Carl Friedrich Philipp von Martius. He also published works on the flora of Australia, including the plants collected by Carl von Hugel. He wrote several works in conjunction with other scholars, and many of his writings are scattered among the periodicals of his time. Endlicher described many new plant genera, including the genus Sequoia, although Endlicher never offered an explanation for the name, later writers speculated that he must have been inspired by the achievements of the American Indian linguist Sequoyah. John Davis credited Endlicher with naming the new species of redwood Sequoyah gigantea in 1847, recent scholarship has convincingly rebutted this hypothesis, Endlicher appears to have been thinking of the Latin for sequence. The genus Endlicheria of the family Lauraceae was named in his honour, Flora Brasiliensis Genera Plantarum Secundum Ordines Naturales Disposita Synopsis Coniferarum Die Medicinal-Pflanzen der österreichischen Pharmakopöe, ein Handbuch für Ärzte und Apotheker.

Ge'ez script
–
Geez is a script used as an abugida for several languages of Ethiopia and Eritrea. It originated as an abjad and was first used to write Geez, now the language of the Ethiopian Orthodox Tewahedo Church. In Amharic and Tigrinya, the script is often called fidäl, the Geez script has been adapted to write other, mostly Semitic, languages, particularly Amharic in Ethiopia, and Tigrinya in both Eritrea and Ethiopia. It is also used for Sebatbeit, Meen, and most other languages of Ethiopia, in Eritrea it is used for Tigre, and it has traditionally been used for Blin, a Cushitic language. Tigre, spoken in western and northern Eritrea, is considered to resemble Geez more than do the other derivative languages, some other languages in the Horn of Africa, such as Oromo, used to be written using Geez, but have migrated to Latin-based orthographies. For the representation of sounds, this uses a system that is common among linguists who work on Ethiopian Semitic languages. This differs somewhat from the conventions of the International Phonetic Alphabet, see the articles on the individual languages for information on the pronunciation. The earliest inscriptions of Semitic languages in Eritrea and Ethiopia date to the 9th century BC in Epigraphic South Arabian, after the 7th and 6th centuries BC, however, variants of the script arose, evolving in the direction of the Geez abugida. This evolution can be seen most clearly in evidence from inscriptions in Tigray region in northern Ethiopia, at least one of Wazebas coins from the late 3rd or early 4th century contains a vocalized letter, some 30 or so years before Ezana. It has been argued that the marking pattern of the script reflects a South Asian system. On the other hand, emphatic P̣ait ጰ, a Geez innovation, is a modification of Ṣädai ጸ, while Pesa ፐ is based on Tawe ተ. Thus, there are 24 correspondences of Geez and the South Arabian alphabet, Many of the names are cognate with those of Phoenician. Two alphabets were used to write the Geez language, an abjad and later an abugida. The abjad, used until c.330 AD, had 26 consonantal letters, h, l, ḥ, m, ś, r, s, ḳ, b, t, ḫ, n, ʾ, k, w, ʿ, z, y, d, g, ṭ, p̣, ṣ, ṣ́, f, p Vowels were not indicated. Modern Geez is written left to right. The Geez abugida developed under the influence of Christian scripture by adding obligatory vocalic diacritics to the consonantal letters. The diacritics for the vowels, u, i, a, e, ə, o, were fused with the consonants in a recognizable but slightly irregular way, the original form of the consonant was used when the vowel was ä, the so-called inherent vowel. The resulting forms are shown below in their traditional order, for some consonants, there is an eighth form for the diphthong -wa or -oa, and a ninth for -yä

Specials (Unicode block)
–
Specials is a short Unicode block allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 codepoints, five are assigned as of Unicode 9, U+FFFD � REPLACEMENT CHARACTER used to replace an unknown, unrecognized or unrepresentable character U+FFFE <noncharacter-FFFE> not a character. FFFE and FFFF are not unassigned in the sense. They can be used to guess a texts encoding scheme, since any text containing these is by not a correctly encoded Unicode text. The replacement character � is a found in the Unicode standard at codepoint U+FFFD in the Specials table. It is used to indicate problems when a system is unable to render a stream of data to a correct symbol and it is usually seen when the data is invalid and does not match any character, Consider a text file containing the German word für in the ISO-8859-1 encoding. This file is now opened with an editor that assumes the input is UTF-8. The first and last byte are valid UTF-8 encodings of ASCII, therefore, a text editor could replace this byte with the replacement character symbol to produce a valid string of Unicode code points. The whole string now displays like this, f�r, a poorly implemented text editor might save the replacement in UTF-8 form, the text file data will then look like this, 0x66 0xEF 0xBF 0xBD 0x72, which will be displayed in ISO-8859-1 as f�r. Since the replacement is the same for all errors this makes it impossible to recover the original character, a better design is to preserve the original bytes, including the error, and only convert to the replacement when displaying the text. This will allow the text editor to save the original byte sequence and it has become increasingly common for software to interpret invalid UTF-8 by guessing the bytes are in another byte-based encoding such as ISO-8859-1. This allows correct display of both valid and invalid UTF-8 pasted together, Unicode control characters UTF-8 Mojibake Unicodes Specials table Decodeunicodes entry for the replacement character

Arabic
–
Arabic is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the lingua franca of the Arab world. Arabic is also the language of 1.7 billion Muslims. It is one of six languages of the United Nations. The modern written language is derived from the language of the Quran and it is widely taught in schools and universities, and is used to varying degrees in workplaces, government, and the media. The two formal varieties are grouped together as Literary Arabic, which is the language of 26 states. Modern Standard Arabic largely follows the standards of Quranic Arabic. Much of the new vocabulary is used to denote concepts that have arisen in the post-Quranic era, Arabic has influenced many languages around the globe throughout its history. During the Middle Ages, Literary Arabic was a vehicle of culture in Europe, especially in science, mathematics. As a result, many European languages have borrowed many words from it. Many words of Arabic origin are found in ancient languages like Latin. Balkan languages, including Greek, have acquired a significant number of Arabic words through contact with Ottoman Turkish. Arabic has also borrowed words from languages including Greek and Persian in medieval times. Arabic is a Central Semitic language, closely related to the Northwest Semitic languages, the Ancient South Arabian languages, the Semitic languages changed a great deal between Proto-Semitic and the establishment of the Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include, The conversion of the suffix-conjugated stative formation into a past tense, the conversion of the prefix-conjugated preterite-tense formation into a present tense. The elimination of other prefix-conjugated mood/aspect forms in favor of new moods formed by endings attached to the prefix-conjugation forms, the development of an internal passive. These features are evidence of descent from a hypothetical ancestor. In the southwest, various Central Semitic languages both belonging to and outside of the Ancient South Arabian family were spoken and it is also believed that the ancestors of the Modern South Arabian languages were also spoken in southern Arabia at this time. To the north, in the oases of northern Hijaz, Dadanitic and Taymanitic held some prestige as inscriptional languages, in Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested

Horn of Africa
–
The Horn of Africa is a peninsula in Northeast Africa. It juts hundreds of kilometers into the Arabian Sea and Indian Ocean, the area is the easternmost projection of the African continent. The Horn of Africa denotes the region containing the countries of Djibouti, Eritrea, Ethiopia and it covers approximately 2,000,000 km2 and is inhabited by roughly 115 million people. Regional studies on the Horn of Africa are carried out, among others, shell middens 125,000 years old have been found in Eritrea, indicating the diet of early humans included seafood obtained by beachcombing. According to both genetic and fossil evidence, archaic Homo sapiens evolved to modern humans solely in Africa between 200,000 and 100,000 years ago. Evidence to support the theory that recent modern humans originated in East Africa is not conclusive, today at the Bab-el-Mandeb straits, the Red Sea is about 12 miles wide, but 50,000 years ago it was much narrower and sea levels were 70 meters lower. Though the straits were never closed, there may have been islands in between which could be reached using simple rafts. It has been estimated that from a population of 2,000 to 5,000 individuals in Africa, according to linguists, the first Afro-Asiatic-speaking populations arrived in the region during the ensuing Neolithic era from the familys proposed urheimat in the Nile Valley, or the Near East. Other scholars propose that the Afro-Asiatic family developed in situ in the Horn, genetic analysis also indicates that, beginning in the pre-agricultural period, settlers from the Near East founded communities in Northeast Africa. These early settlements eventually gave rise to the Afro-Asiatic-speaking populations in the Horn, dʿmt was a kingdom located in Eritrea and northern Ethiopia, which existed during the 8th and 7th centuries BCE. With its capital at Yeha, the kingdom developed irrigation schemes, used plows, grew millet, the Kingdom of Aksum was an ancient state located in the highlands of present-day Ethiopia and Eritrea, which thrived between the 1st and 7th centuries CE. A major player in the commerce between the Roman Empire and Ancient India, Aksums rulers facilitated trade by minting their own currency. Under Ezana, the kingdom of Aksum became the first major empire to adopt Christianity, northern Somalia was an important link in the Horn, connecting the regions commerce with the rest of the ancient world. Somali sailors and merchants were the suppliers of frankincense, myrrh and spices. The Romans consequently began to refer to the region as Regio Aromatica, in the classical era, several flourishing Somali city-states such as Opone, Mosylon and Malao also competed with the Sabaeans, Parthians and Axumites for the rich Indo-Greco-Roman trade. The city of Mogadishu came to be known as the City of Islam, the Sultanate of Showa, established in 896, was one of the oldest local Muslim states. It was centered in the former Shewa province in central Ethiopia, the polity was succeeded by the Sultanate of Ifat around 1285. Ifat was governed from its capital at Zeila in northern Somalia and was the easternmost district of the former Shewa Sultanate, the Adal Sultanate was a medieval multi-ethnic Muslim state centered in the Horn region

Arabian Peninsula
–
The Arabian Peninsula, simplified Arabia is a peninsula of Western Asia situated northeast of Africa on the Arabian plate. From a geological perspective, it is considered a subcontinent of Asia and it is the largest peninsula in the world, at 3,237,500 km2. The Arabian Peninsula consists of the countries Yemen, Oman, Qatar, Bahrain, Kuwait, Saudi Arabia, the Arabian Peninsula plays a critical geopolitical role in the Middle East and the Arab world due to its vast reserves of oil and natural gas. Before the modern era, it was divided into four regions, Hejaz, Najd, Southern Arabia. Hejaz and Najd make up most of Saudi Arabia, Southern Arabia consists of Yemen and some parts of Saudi Arabia and Oman. Eastern Arabia consists of the coastal strip of the Persian Gulf. The most prominent feature of the peninsula is desert, but in the southwest there are mountain ranges, harrat ash Shaam is a large volcanic field that extends from the northwestern Arabian Peninsula into Jordan and southern Syria. The peninsulas constituent countries are Kuwait, Bahrain, Qatar, the island nation of Bahrain lies off the east coast of the peninsula. Six countries form the Gulf Cooperation Council, however, this is a disputed term. The Kingdom of Saudi Arabia covers the part of the peninsula. The majority of the population of the live in Saudi Arabia. The peninsula contains the worlds largest reserves of oil, Saudi Arabia and the UAE are economically the wealthiest in the region. Qatar, a peninsula in the Persian Gulf on the larger peninsula, is home of the Arabic-language television station Al Jazeera. Kuwait, on the border with Iraq, is an important country strategically, though historically lightly populated, political Arabia is noted for a high population growth rate - as the result of both very strong inflows of migrant labor as well as sustained high birth rates. The population tends to be young and heavily skewed gender ratio dominated by males. In many states, the number of South Asians exceeds that of the local citizenry, the four smallest states, which have their entire coastlines on the Persian Gulf, exhibit the worlds most extreme population growth, roughly tripling every 20 years. In 2014, the population of the Arabian Peninsula was 77,983,936. Listed here are the human Y-chromosome DNA haplogroups in Arabia Haplogroup J is the most abundant component in the Arabian peninsula and its two main subclades, show opposite latitudinal gradients in the Middle East

Alkaloid
–
Alkaloids are a group of naturally occurring chemical compounds that mostly contain basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties, some synthetic compounds of similar structure are also termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other such as chlorine, bromine. Alkaloids are produced by a variety of organisms including bacteria, fungi, plants. They can be purified from crude extracts of these organisms by acid-base extraction, many have found use in traditional or modern medicine, or as starting points for drug discovery. Other alkaloids possess psychotropic and stimulant activities, and have used in entheogenic rituals or as recreational drugs. Although alkaloids act on a diversity of systems in humans and other animals. The boundary between alkaloids and other nitrogen-containing natural compounds is not clear-cut, Compounds like amino acid peptides, proteins, nucleotides, nucleic acid, amines, and antibiotics are usually not called alkaloids. Natural compounds containing nitrogen in the position are usually classified as amines rather than as alkaloids. Some authors, however, consider alkaloids a special case of amines, the name alkaloids was introduced in 1819 by the German chemist Carl Friedrich Wilhelm Meißner, and is derived from late Latin root Latin, alkali and the suffix Greek, -οειδής – like. However, the term came into use only after the publication of a review article by Oscar Jacobsen in the chemical dictionary of Albert Ladenburg in the 1880s. There is no method of naming alkaloids. Many individual names are formed by adding the suffix ine to the species or genus name, for example, atropine is isolated from the plant Atropa belladonna, strychnine is obtained from the seed of Strychnine tree. If several alkaloids are extracted from one plant then their names often contain suffixes idine, anine, aline, inine etc. There are also at least 86 alkaloids whose names contain the root vin because they are extracted from plants such as Vinca rosea. Alkaloid-containing plants have been used by humans since ancient times for therapeutic, for example, medicinal plants have been known in the Mesopotamia at least around 2000 BC. The Odyssey of Homer referred to a given to Helen by the Egyptian queen. It is believed that the gift was an opium-containing drug, a Chinese book on houseplants written in 1st–3rd centuries BC mentioned a medical use of Ephedra and opium poppies

Cathinone
–
Cathinone /ˈkæθᵻnoʊn/ is a monoamine alkaloid found in the shrub Catha edulis and is chemically similar to ephedrine, cathine, methcathinone and other amphetamines. It is probably the main contributor to the stimulant effect of Catha edulis, Cathinone differs from many other amphetamines in that it has a ketone functional group. Other phenethylamines that share this structure include the stimulants methcathinone, MDPV, mephedrone, Khat has been cultivated in the Horn of Africa and Arabian Peninsula region of the world for thousands of years. It is most commonly chewed for the effect it produces. The active ingredient was first proposed in 1930, when cathine was identified as a predominant alkaloid in the plant. Cathine was thought to be the active ingredient in khat until the 1960s. In 1975, the United Nations Narcotic Laboratory analyzed khat leaves from Yemen, Kenya and Madagascar and found the presence of a different alkaloid, Cathinone is a similar molecule to cathine, but is much more abundant in younger plants. This finding caused scientists to speculate about whether cathinone was the active ingredient in khat. A study was conducted in 1994 to test the effects of cathinone, six volunteers who had never chewed khat were given an active khat sample and a cathinone-free placebo sample. The researchers analyzed the participants’ moods, activity levels and blood pressure before and this analysis showed that cathinone produced amphetamine-like symptoms, leading the researchers to confirm that cathinone, not cathine, is the active ingredient in khat leaves. Over 20 million people in the Arabian Peninsula and East Africa chew khat leaves daily and it is an important piece of the culture and economy in this region, especially in Ethiopia, where khat is said to have originated, Kenya, Djibouti, and Yemen. Men usually chew it during parties or other social gatherings while smoking cigarettes, farmers and other workers also use khat in the afternoon to reduce fatigue and hunger as the day goes on. It functions like the caffeine in a cup of coffee as an anti-fatigue drug. Students and drivers have known to use it to stay alert for longer periods of time. In order to produce its effects, khat leaves should be chewed fresh. The fresh leaves have a concentration of cathinone. Waiting too long after cultivation to chew the leaf will allow the cathinone to break down into its less potent form, because of the need for quick chewing, it is a habit that has historically been prevalent only where the plant grows. However, in the recent years with improvements in road and air transport, the cultivation of khat in Yemen is a highly profitable industry for farmers

Stimulant
–
Stimulants is an overarching term that covers many drugs including those that increase activity of the body, drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. Due to their rendering a characteristic up feeling, stimulants are also referred to as uppers. Depressants or downers, which decrease mental and/or physical function, are in stark contrast to stimulants and are considered to be the functionally opposite drug class, Stimulants are widely used throughout the world as prescription medicines as well as without a prescription as performance-enhancing or recreational drugs. The most frequently prescribed stimulants as of 2013 were lisdexamfetamine, methylphenidate and it is estimated that the percent of the population that has abused amphetamines, cocaine and MDMA combined is between. 8% and 2. 1%. Stimulants in therapeutic doses, such as given to patients with ADHD, increases ability to focus, vigor, sociability, libido. However, in higher doses stimulants may actually decrease the ability to focus, in higher doses stimulants may also produce euphoria, vigor, and decrease need for sleep. Many, but not all, stimulants have ergogenic effects, Drugs such as ephedrine, pseudoephedrine, amphetamine and methylphenidate have well documented ergogenic effects, while drugs such as cocaine and methamphetamine have the opposite effect. In some cases psychiatric phenomenon may emerge such as stimulant psychosis, paranoia, acute toxicity has been reportedly associated with a homicide, paranoia, aggressive behavior, motor dysfunction, and punding. The violent and aggressive behavior associated with acute stimulant toxicity may partially be driven by paranoia, most drugs classified as stimulants are sympathomimetics, that is they stimulate the sympathetic branch of the autonomic nervous system. This leads to such as mydriasis, increased heart rate, blood pressure, respiratory rate. When these changes become pathological, they are called arrhythmia, hypertension, and hyperthermia, however given the complexity of the mechanisms that underly these potentially fatal outcomes of acute stimulant toxicity, it is impossible to determine what dose may be lethal. Assessment of the effects of stimulants is relevant given the large population currently taking stimulants. A systematic review of cardiovascular effects of prescription stimulants found no association in children, a review over a four-year period found that there were few negative effects of stimulant treatment, but stressed the need for longer term studies. A review of a long period of prescription stimulate use in those with ADHD found that cardiovascular side effects were limited to transient increases in blood pressure only. Initiation of stimulant treatment in those with ADHD in early childhood appears to carry benefits into adulthood with regard to social and cognitive functioning, Abuse of prescription stimulants or of illicit stimulants carries many negative health risks. Abuse of cocaine, depending upon route of administration, increases risk of disease, stroke. Cocaine may also increase risk for disease, as well as damage nasal cartilage. Abuse of methamphetamine produces similar effects as well as marked degeneration of dopaminergic neurons, Drugs used to treat sleep disorders such as excessive daytime sleepiness are called eugeroics, and include notable stimulants such as modafinil

Euphoria
–
Euphoria is an affective state in which a person experiences pleasure or excitement and intense feelings of well-being and happiness. Certain drugs, many of which are addictive, can cause euphoria, similarly, certain natural rewards and social activities, such as aerobic exercise, laughter, listening to emotionally arousing music, music-making, and dancing, can induce a state of euphoria. Euphoria is also a symptom of certain neurological or neuropsychiatric disorders, romantic love and components of the human sexual response cycle are also associated with the induction of euphoria. According to Kent Berridge, an affective neuroscientist, intense euphoria occurs from the activation of every hedonic hotspot within the brains reward system. The word euphoria is derived from the Ancient Greek terms εὐφορία, εὖ eu meaning well and it is semantically opposite to dysphoria. A1706 English dictionary defined euphoria as the bearing of the Operation of a Medicine. A1903 article in The Boston Daily Globe refers to euphoria as pleasant excitement, in 1920 Popular Science magazine described euphoria as a high sounding name meaning feeling fit, normally making life worth living, motivating drug use, and ill formed in certain mental illnesses. In 1940 The Journal of Psychology defined euphoria as a state of well being. However, in 1957 British pharmacologist D. A. Cahal did not regard opioid euphoria as medically undesirable, the 1977 edition of A Concise Encyclopaedia of Psychiatry called euphoria a mood of contentment and well-being, with pathologic associations when used in a psychiatric context. As a sign of disease, it was described as bland and out of context. Many different types of stimuli can induce euphoria, including drugs, natural rewards. Affective disorders such as mania or bipolar disorder can involve euphoria as a symptom. Euphoria can occur as a result of dancing to music, music-making, neuroimaging studies have demonstrated that the reward system plays a central role in mediating music-induced pleasure. Pleasurable emotionally arousing music strongly increases dopamine neurotransmission in the pathways that project to the striatum. A euphoriant is a type of drug which tends to induce euphoria. Most euphoriants are addictive drugs due to their properties and ability to activate the brains reward system. Dopaminergic stimulants like amphetamine, methamphetamine, cocaine, MDMA, nicotine is a parasympathetic stimulant that acts as a mild euphoriant in some people. Certain depressants can produce euphoria, some of the euphoriant drugs in this class include drinking alcohol in moderate doses, γ-hydroxybutyric acid, some barbiturates and benzodiazepines may cause euphoria

Coca
–
Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. The plant is grown as a crop in Argentina, Bolivia, Colombia, Ecuador. There are some reports that the plant is being cultivated in the south of Mexico as a cash crop and it also plays a role in many traditional Andean cultures as well as the Sierra Nevada de Santa Marta. Coca is known throughout the world for its psychoactive alkaloid, cocaine, the alkaloid content of coca leaves is low, between 0. 25% and 0. 77%. This means that chewing the leaves or drinking coca tea does not produce the high people experience with cocaine, Coca leaf extract had been used in Coca-Cola products since 1885, with cocaine being completely eliminated from the products in or around 1929. Extraction of cocaine from coca requires several solvents and a process known as an acid / base extraction. The coca plant resembles a blackthorn bush, and grows to a height of 2 to 3 metres, the branches are straight, and the leaves are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two curved lines, one line on each side of the midrib, and more conspicuous on the under face of the leaf. The flowers mature into red berries, the leaves are sometimes eaten by the larvae of the moth Eloria noyesi. Erythroxylum coca var. ipadu – cultivated in the lowland Amazon Basin in Peru, Erythroxylum novogranatense Erythroxylum novogranatense var. novogranatense – a highland variety that is utilized in lowland areas. It is cultivated in drier regions found in Colombia, however, E. novogranatense is very adaptable to varying ecological conditions. The leaves have parallel lines on side of the central vein. Erythroxylum novogranatense var. truxillense – grown primarily in Peru and Colombia, the leaves of E. novogranatense var. truxillense does not have parallel lines on either side of the central vein like all other varieties. All four of the cultivated cocas were domesticated in pre-Columbian times and are closely related to each other than to any other species. There are two theories relating to the evolution of the cultivated cocas. Recent research based on genetic evidence does not support this linear evolution, there may be a common, but undiscovered ancestor. Wild populations of Erythroxylum coca var. coca are found in the eastern Andes, the two subspecies of Erythroxylum coca are almost indistinguishable phenotypically. Erythroxylum novogranatense var. novogranatense and Erythroxylum novogranatense var. truxillense are phenotypically similar, under the older Cronquist system of classifying flowering plants, this was placed in an order Linales, more modern systems place it in the order Malpighiales

Areca nut
–
The areca nut is the seed of the areca palm, which grows in much of the tropical Pacific, Southeast and South Asia, and parts of east Africa. This seed is referred to as betel nut so it is easily confused with betel leaves that are often used to wrap it. The term areca originated from a South Asian word, Malayalam, Adakka during the 16th century, consumption has many harmful effects on health and is carcinogenic to humans. Various compounds present in the nut, most importantly arecoline, contribute to changes in the oral mucosa. As with chewing tobacco, its use is discouraged by preventive efforts, the areca nut is not a true nut, but rather a fruit categorized as a berry. It is commercially available in dried, cured and fresh forms, when the husk of the fresh fruit is green, the nut inside is soft enough to be cut with a typical knife. In the ripe fruit, the husk becomes yellow or orange and, as it dries, at that stage, the areca nut can only be sliced using a special scissors-like cutter. Usually for chewing, a few slices of the nut are wrapped in a betel leaf along with calcium hydroxide and may include clove, cardamom, betel leaf has a fresh, peppery taste, but it can also be bitter to varying degrees depending on the variety. The betel leaf chewed along with the nut contains eugenol, another vasoconstrictor, tobacco leaf is often added to the mixture, thereby adding the effect of nicotine. In parts of India, Sri Lanka and southern China, areca nuts are not only chewed along with betel leaf, powdered areca nut is used as a constituent in some dentifrices. According to traditional Ayurvedic medicine, chewing areca nut and betel leaf is a remedy against bad breath. Diplomat Edmund Roberts noted that Chinese people would mix areca nut with Uncaria gambir during his visit to China in the 1830s, after chewing a betelnut, the red residue from chewing the betelnut, buai pekpek, is generally spat out and is considered an eyesore. This has led many places to ban chewing buai as many people spit the pekpek on the rather than in a spit cup or waste receptacle. Chewing the mixture of areca nut and betel leaf is a tradition and it is not known how or when the areca nut and the betel leaf were first combined into one psychoactive drug. Archaeological evidence from Thailand, Indonesia and the Philippines suggests they have used in tandem for at least 4000 years. In Vietnam, the nut and the betel leaf are such important symbols of love and marriage that in Vietnamese the phrase matters of betel. The tradition of chewing areca nuts starts the talk between the parents and the brides parents about the young couples marriage. Therefore, the leaves and juices are used ceremonially in Vietnamese weddings, Malay culture and tradition hold betel nut and leaves in high esteem

World Health Organization
–
The World Health Organization is a specialised agency of the United Nations that is concerned with international public health. It was established on 7 April 1948, headquartered in Geneva, the WHO is a member of the United Nations Development Group. Its predecessor, the Health Organization, was an agency of the League of Nations, the constitution of the World Health Organization had been signed by 61 countries on 22 July 1946, with the first meeting of the World Health Assembly finishing on 24 July 1948. It incorporated the Office international dhygiène publique and the League of Nations Health Organization, since its creation, it has played a leading role in the eradication of smallpox. The WHO is responsible for the World Health Report, an international publication on health, the worldwide World Health Survey. The head of WHO is Margaret Chan, the 2014/2015 proposed budget of the WHO is about US$4 billion. About US$930 million are to be provided by member states with a further US$3 billion to be from voluntary contributions, after failing to get a resolution passed on the subject, Alger Hiss, the Secretary General of the conference, recommended using a declaration to establish such an organisation. Dr. Sze and other delegates lobbied and a declaration passed calling for a conference on health. The use of the world, rather than international, emphasised the truly global nature of what the organisation was seeking to achieve. The constitution of the World Health Organization was signed by all 51 countries of the United Nations and it thus became the first specialised agency of the United Nations to which every member subscribed. Its constitution formally came into force on the first World Health Day on 7 April 1948, the first meeting of the World Health Assembly finished on 24 July 1948, having secured a budget of US$5 million for the 1949 year. Andrija Stampar was the Assemblys first president, and G. Brock Chisholm was appointed Director-General of WHO and its first priorities were to control the spread of malaria, tuberculosis and sexually transmitted infections, and to improve maternal and child health, nutrition and environmental hygiene. Its first legislative act was concerning the compilation of statistics on the spread. The logo of the World Health Organization features the Rod of Asclepius as a symbol for healing, in 1947 the WHO established an epidemiological information service via telex, and by 1950 a mass tuberculosis inoculation drive using the BCG vaccine was under way. In 1955, the eradication programme was launched, although it was later altered in objective. 1965 saw the first report on diabetes mellitus and the creation of the International Agency for Research on Cancer. In 1958, Viktor Zhdanov, Deputy Minister of Health for the USSR, called on the World Health Assembly to undertake an initiative to eradicate smallpox. At this point,2 million people were dying from smallpox every year, in 1966, WHO moved into its headquarters building

Canada
–
Canada is a country in the northern half of North America. Canadas border with the United States is the worlds longest binational land border, the majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its territory being dominated by forest and tundra. It is highly urbanized with 82 per cent of the 35.15 million people concentrated in large and medium-sized cities, One third of the population lives in the three largest cities, Toronto, Montreal and Vancouver. Its capital is Ottawa, and other urban areas include Calgary, Edmonton, Quebec City, Winnipeg. Various aboriginal peoples had inhabited what is now Canada for thousands of years prior to European colonization. Pursuant to the British North America Act, on July 1,1867, the colonies of Canada, New Brunswick and this began an accretion of provinces and territories to the mostly self-governing Dominion to the present ten provinces and three territories forming modern Canada. With the Constitution Act 1982, Canada took over authority, removing the last remaining ties of legal dependence on the Parliament of the United Kingdom. Canada is a parliamentary democracy and a constitutional monarchy, with Queen Elizabeth II being the head of state. The country is officially bilingual at the federal level and it is one of the worlds most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Its advanced economy is the eleventh largest in the world, relying chiefly upon its abundant natural resources, Canadas long and complex relationship with the United States has had a significant impact on its economy and culture. Canada is a country and has the tenth highest nominal per capita income globally as well as the ninth highest ranking in the Human Development Index. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, Canada is an influential nation in the world, primarily due to its inclusive values, years of prosperity and stability, stable economy, and efficient military. While a variety of theories have been postulated for the origins of Canada. In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona, from the 16th to the early 18th century Canada referred to the part of New France that lay along the St. Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named The Canadas, until their union as the British Province of Canada in 1841. Upon Confederation in 1867, Canada was adopted as the name for the new country at the London Conference. The transition away from the use of Dominion was formally reflected in 1982 with the passage of the Canada Act, later that year, the name of national holiday was changed from Dominion Day to Canada Day

It includes 16 constituent states, covers an area of 357,021 square kilometres, with about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular destination in the world. Germanys capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr, other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf and Leipzig. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity, a region named Germania was documented before 100 AD. During the Migration Period the Germanic tribes expanded southward, beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation, in 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the German Revolution of 1918–1919, the Empire was replaced by the parliamentary Weimar Republic, the establishment of the national socialist dictatorship in 1933 led to World War II and the Holocaust. After a period of Allied occupation, two German states were founded, the Federal Republic of Germany and the German Democratic Republic, in 1990, the country was reunified. In the 21st century, Germany is a power and has the worlds fourth-largest economy by nominal GDP. As a global leader in industrial and technological sectors, it is both the worlds third-largest exporter and importer of goods. Germany is a country with a very high standard of living sustained by a skilled. It upholds a social security and universal health system, environmental protection. Germany was a member of the European Economic Community in 1957. It is part of the Schengen Area, and became a co-founder of the Eurozone in 1999, Germany is a member of the United Nations, NATO, the G8, the G20, and the OECD. The national military expenditure is the 9th highest in the world, the English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. This in turn descends from Proto-Germanic *þiudiskaz popular, derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- people, the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago.

The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Djibouti, officially the Republic of Djibouti, is a country located in the Horn of Africa. It is bordered by Eritrea in the north, Ethiopia in the west and south, the remainder of the border is formed by the Red Sea and the Gulf of Aden at the east. Djibouti occupies an area of just 23,200 km2. In antiquity, the territory was part of the Land of Punt and then the Sabean, nearby Zeila was the seat of the medieval Adal and Ifat Sultanates. It was subsequently renamed to the French Territory of the Afars, a decade later, the Djiboutian people voted for independence. This officially marked the establishment of the Republic of Djibouti, named after its capital city, Djibouti joined the United Nations the same year, on 20 September 1977. In the early 1990s, tensions over government representation led to armed conflict, Djibouti is a multi-ethnic nation with a population of over 846,687 inhabitants. Arabic and French are the two official languages. About 94% of residents adhere to Islam, a religion that has been predominant in the region for more than 1,000 years, the Somali Issa and Afar make up the two largest ethnic groups. Both speak Afroasiatic languages, which serve as recognized national languages, Djibouti is strategically located near some of the worlds busiest shipping lanes, controlling access to the Red Sea and Indian Ocean. It serves as a key refueling and transshipment center, and is the principal port for imports from. A burgeoning commercial hub, the nation is the site of various military bases. The Intergovernmental Authority on Development regional body also has its headquarters in Djibouti City, the Djibouti area has been inhabited since at least the Neolithic. According to linguists, the first Afroasiatic-speaking populations arrived in the region during this period from the familys proposed urheimat in the Nile Valley, other scholars propose that the Afroasiatic family developed in situ in the Horn, with its speakers subsequently dispersing from there. Pottery predating the mid-2nd millennium has been found at Asa Koma, the sites ware is characterized by punctate and incision geometric designs, which bear a similarity to the Sabir culture phase 1 ceramics from Malayba in Southern Arabia. Long-horned humpless cattle bones have likewise been discovered at Asa Koma, rock art of what appear to be antelopes and a giraffe are also found at Dorra and Balho. Handoga, dated to the fourth millennium BP, has in turn yielded obsidian microliths, additionally, between Djibouti City and Loyada are a number of anthropomorphic and phallic stelae. The structures are associated with graves of rectangular shape that are flanked by vertical slabs, the Djibouti-Loyada stelae are of uncertain age, and some of them are adorned with a T-shaped symbol

Kenya
–
Kenya, officially the Republic of Kenya, is a country in Africa and a founding member of the East African Community. Its capital and largest city is Nairobi and it is bordered by Tanzania to the south and southwest, Uganda to the west, South Sudan to the north-west, Ethiopia to the north and Somalia to the north-east. Kenya covers 581,309 km2, and had a population of approximately 48 million people in January 2017, Kenya has a warm and humid tropical climate on its Indian Ocean coastline. The climate is cooler in the grasslands around the capital city, Nairobi, and especially closer to Mount Kenya. Further inland are highlands in Central and Rift Valley regions where tea, in the West are Nyanza and Western regions, there is an equatorial, hot and dry climate which becomes humid around Lake Victoria, the largest tropical fresh-water lake in the world. This gives way to temperate and forested areas in the neighbouring western region. The north-eastern regions along the border with Somalia and Ethiopia are arid and semi-arid areas with near-desert landscapes, Kenya is known for its world class athletes in track and field and rugby. The African Great Lakes region, which Kenya is a part of, has been inhabited by humans since the Lower Paleolithic period, by the first millennium AD, the Bantu expansion had reached the area from West-Central Africa. Bantu and Nilotic populations together constitute around 97% of the nations residents, European and Arab presence in coastal Mombasa dates to the Early Modern period, European exploration of the interior began in the 19th century. The British Empire established the East Africa Protectorate in 1895, which starting in 1920 gave way to the Kenya Colony, Kenya obtained independence in December 1963. Following a referendum in August 2010 and adoption of a new constitution, Kenya is now divided into 47 semi-autonomous counties, the capital, Nairobi, is a regional commercial hub. The economy of Kenya is the largest by GDP in East, agriculture is a major employer, the country traditionally exports tea and coffee and has more recently begun to export fresh flowers to Europe. The service industry is also an economic driver. Additionally, Kenya is a member of the East African Community trading bloc, the Republic of Kenya is named after Mount Kenya. The origin of the name Kenya is not clear, but perhaps linked to the Kikuyu, Embu and Kamba words Kirinyaga, Kirenyaa, if so, then the British may not so much have mispronounced it, as misspelled it. In the 19th century, the German explorer Johann Ludwig Krapf was staying with the Bantu Kamba people when he first spotted the mountain. On asking for the name of the mountain, he was told Kĩ-Nyaa or Kĩĩma- Kĩĩnyaa probably because the pattern of black rock, the Agikuyu, who inhabit the slopes of Mt. Kenya, call it Kĩrĩma Kĩrĩnyaga in Kikuyu, which is quite similar to the Kamba name. Ludwig Krapf recorded the name as both Kenia and Kegnia believed by most to be a corruption of the Kamba version, others say that this was—on the contrary—a very precise notation of a correct African pronunciation /ˈkɛnjə/

Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a country located in the Horn of Africa. It shares borders with Eritrea to the north and northeast, Djibouti and Somalia to the east, Sudan and South Sudan to the west, and Kenya to the south. With nearly 100 million inhabitants, Ethiopia is the most populous landlocked country in the world and it occupies a total area of 1,100,000 square kilometres, and its capital and largest city is Addis Ababa. Some of the oldest evidence for modern humans has been found in Ethiopia. It is widely considered as the region from modern humans first set out for the Middle East. According to linguists, the first Afroasiatic-speaking populations settled in the Horn region during the ensuing Neolithic era, tracing its roots to the 2nd millennium BC, Ethiopia was a monarchy for most of its history. During the first centuries AD, the Kingdom of Aksum maintained a unified civilization in the region, subsequently, many African nations adopted the colors of Ethiopias flag following their independence. It was the first independent African member of the 20th-century League of Nations, Ethiopias ancient Geez script, also known as Ethiopic, is one of the oldest alphabets still in use in the world. The Ethiopian calendar, which is seven years and three months behind the Gregorian calendar, co-exists alongside the Borana calendar. A slight majority of the population adheres to Christianity, while around a third follows Islam, the country is the site of the Migration to Abyssinia and the oldest Muslim settlement in Africa at Negash. A substantial population of Ethiopian Jews, known as Bete Israel, resided in Ethiopia until the 1980s, Ethiopia is a multilingual nation with around 80 ethnolinguistic groups, the four largest of which are the Oromiffa, Amhara, Somali, and Tigrayans. Most people in the country speak Afroasiatic languages of the Cushitic or Semitic branches, additionally, Omotic languages are spoken by ethnic minority groups inhabiting the southern regions. Nilo-Saharan languages are spoken by the nations Nilotic ethnic minorities. Ethiopia is the place of origin for the coffee bean which originated from the place called Kefa and it is a land of natural contrasts, with its vast fertile West, jungles, and numerous rivers, and the worlds hottest settlement of Dallol in its north. The Ethiopian Highlands are Africas largest continuous mountain ranges, and Sof Omar Caves contain Africas largest cave, Ethiopia has the most UNESCO World Heritage Sites in Africa. Ethiopia is one of the members of the UN, the Group of 24, the Non-Aligned Movement, G-77. In the 1970s and 1980s, Ethiopia suffered from civil wars, the country has begun to recover recently however, and now has the largest economy in East Africa and Central Africa. According to Global Fire Power, Ethiopia has the 42nd most powerful military in the world, the origin of the word Ethiopia is uncertain

Somalia, officially the Federal Republic of Somalia, is a country located in the Horn of Africa. It is bordered by Ethiopia to the west, Djibouti to the northwest, the Gulf of Aden to the north, the Indian Ocean to the east, Somalia has the longest coastline on Africas mainland, and its terrain consists mainly of plateaus, plains and highlands. Climatically, hot conditions prevail year-round, with monsoon winds. Somalia has an population of around 12.3 million. Around 85% of its residents are ethnic Somalis, who have inhabited the northern part of the country. Ethnic minorities are largely concentrated in the southern regions, the official languages of Somalia are Somali and Arabic, both of which belong to the Afroasiatic family. Most people in the country are Muslim, with the majority being Sunni, in antiquity, Somalia was an important commercial centre. It is among the most probable locations of the fabled ancient Land of Punt, during the Middle Ages, several powerful Somali empires dominated the regional trade, including the Ajuran Empire, the Adal Sultanate, the Warsangali Sultanate, and the Geledi Sultanate. The toponym Somalia was coined by the Italian explorer Luigi Robecchi Bricchetti, Italian occupation lasted until 1941, yielding to British military administration. British Somaliland would remain a protectorate, while Italian Somaliland in 1949 became a United Nations Trusteeship under Italian administration, in 1960, the two regions united to form the independent Somali Republic under a civilian government. The Supreme Revolutionary Council seized power in 1969 and established the Somali Democratic Republic, led by Mohamed Siad Barre, this government later collapsed in 1991 as the Somali Civil War broke out. Various armed factions began competing for influence in the power vacuum, during this period, due to the absence of a central government, Somalia was a failed state, and residents returned to customary and religious law in most regions. A few autonomous regions, including the Somaliland and Puntland administrations emerged in the north, the early 2000s saw the creation of fledgling interim federal administrations. The Transitional National Government was established in 2000, followed by the formation of the Transitional Federal Government in 2004, in 2006, the TFG, assisted by Ethiopian troops, assumed control of most of the nations southern conflict zones from the newly formed Islamic Courts Union. The ICU subsequently splintered into more radical groups such as Al-Shabaab, by mid-2012, the insurgents had lost most of the territory that they had seized. In 2011–2012, a political process providing benchmarks for the establishment of permanent democratic institutions was launched, within this administrative framework a new provisional constitution was passed in August 2012, which reformed Somalia as a federation. Somalia has maintained an informal economy, mainly based on livestock, remittances from Somalis working abroad, Somalia has been inhabited since at least the Paleolithic. During the Stone Age, the Doian and Hargeisan cultures flourished here, the oldest evidence of burial customs in the Horn of Africa comes from cemeteries in Somalia dating back to the 4th millennium BCE

Yemen
–
Yemen, officially known as the Republic of Yemen, is an Arab country in Western Asia, occupying South Arabia, the southern end of the Arabian Peninsula. Yemen is the second-largest country in the peninsula, occupying 527,970 km2, the coastline stretches for about 2,000 km. It is bordered by Saudi Arabia to the north, the Red Sea to the west, the Gulf of Aden and Arabian Sea to the south, although Yemens constitutionally stated capital is the city of Sanaa, the city has been under rebel control since February 2015. Because of this, Yemens capital has been relocated to the port city of Aden. Yemens territory includes more than 200 islands, the largest of these is Socotra, Yemen was the home of the Sabaeans, a trading state that flourished for over a thousand years and probably also included parts of modern-day Ethiopia and Eritrea. In 275 AD, the region came under the rule of the later Jewish-influenced Himyarite Kingdom, Christianity arrived in the fourth century, whereas Judaism and local paganism were already established. Islam spread quickly in the century and Yemenite troops were crucial in the expansion of the early Islamic conquests. Administration of Yemen has long been notoriously difficult, several dynasties emerged from the ninth to 16th centuries, the Rasulid dynasty being the strongest and most prosperous. The country was divided between the Ottoman and British empires in the twentieth century. The Zaydi Mutawakkilite Kingdom of Yemen was established after World War I in North Yemen before the creation of the Yemen Arab Republic in 1962, South Yemen remained a British protectorate known as the Aden Protectorate until 1967 when it became an independent state and later, a Marxist state. The two Yemeni states united to form the modern republic of Yemen in 1990, Yemen is a developing country, and the poorest country in the Middle East. Under the rule of President Ali Abdullah Saleh, Yemen was described as a kleptocracy, according to the 2009 international corruption Perception Index by Transparency International, Yemen ranked 164 out of 182 countries surveyed. President Saleh stepped down and the powers of the presidency were transferred to Vice President Abd Rabbuh Mansur Hadi, the transitional process was disrupted by conflicts between the Houthis and al-Islah, as well as the al-Qaeda insurgency. In September 2014, the Houthis took over Sanaa, later declaring themselves in control of the government in a coup détat, since then, a Saudi-led intervention has taken place, however, it could not stop the civil war. Instead, the Saudis and the others have destroyed some hospitals, schools and homes, Yemen was mentioned in Old South Arabian inscriptions as Yamnat. In Arabic literature, the term includes much greater territory than that of the republic of Yemen. It stretches from the northern Asir Region in southwestern Saudi Arabia to Dhofar Governorate in southern Oman, one etymology derives Yemen from yumn, meaning felicity, as much of the country is fertile. The Romans called it Arabia Felix, as opposed to Arabia Deserta, al-Yaman significantly plays on the notion of the land to the right, when in Mecca facing the dawn, complementary to Al-Sham, the Land to the Left, referring to the Levant

Israel
–
Israel, officially the State of Israel, is a country in the Middle East, on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea. The country contains geographically diverse features within its small area. Israels economy and technology center is Tel Aviv, while its seat of government and proclaimed capital is Jerusalem, in 1947, the United Nations adopted a Partition Plan for Mandatory Palestine recommending the creation of independent Arab and Jewish states and an internationalized Jerusalem. The plan was accepted by the Jewish Agency for Palestine, next year, the Jewish Agency declared the establishment of a Jewish state in Eretz Israel, to be known as the State of Israel. Israel has since fought several wars with neighboring Arab states, in the course of which it has occupied territories including the West Bank, Golan Heights and it extended its laws to the Golan Heights and East Jerusalem, but not the West Bank. Israels occupation of the Palestinian territories is the worlds longest military occupation in modern times, efforts to resolve the Israeli–Palestinian conflict have not resulted in peace. However, peace treaties between Israel and both Egypt and Jordan have successfully been signed, the population of Israel, as defined by the Israel Central Bureau of Statistics, was estimated in 2017 to be 8,671,100 people. It is the worlds only Jewish-majority state, with 74. 8% being designated as Jewish, the countrys second largest group of citizens are Arabs, at 20. 8%. The great majority of Israeli Arabs are Sunni Muslims, including significant numbers of semi-settled Negev Bedouins, other minorities include Arameans, Armenians, Assyrians, Black Hebrew Israelites, Circassians, Maronites and Samaritans. Israel also hosts a significant population of foreign workers and asylum seekers from Africa and Asia, including illegal migrants from Sudan, Eritrea. In its Basic Laws, Israel defines itself as a Jewish, Israel is a representative democracy with a parliamentary system, proportional representation and universal suffrage. The prime minister is head of government and the Knesset is the legislature, Israel is a developed country and an OECD member, with the 35th-largest economy in the world by nominal gross domestic product as of 2016. The country benefits from a skilled workforce and is among the most educated countries in the world with one of the highest percentage of its citizens holding a tertiary education degree. The country has the highest standard of living in the Middle East and the third highest in Asia, in the early weeks of independence, the government chose the term Israeli to denote a citizen of Israel, with the formal announcement made by Minister of Foreign Affairs Moshe Sharett. The names Land of Israel and Children of Israel have historically used to refer to the biblical Kingdom of Israel. The name Israel in these phrases refers to the patriarch Jacob who, jacobs twelve sons became the ancestors of the Israelites, also known as the Twelve Tribes of Israel or Children of Israel. The earliest known artifact to mention the word Israel as a collective is the Merneptah Stele of ancient Egypt. The area is known as the Holy Land, being holy for all Abrahamic religions including Judaism, Christianity, Islam

Drug Enforcement Administration
–
The Drug Enforcement Administration is a United States federal law enforcement agency under the U. S. Department of Justice, tasked with combating drug smuggling and use within the United States. S. It has sole responsibility for coordinating and pursuing U. S. drug investigations both domestic, and abroad, the Drug Enforcement Administration was established on July 1,1973, by Reorganization Plan No.2 of 1973, signed by President Richard Nixon on July 28. It proposed the creation of a federal agency to enforce the federal drug laws as well as consolidate and coordinate the governments drug control activities. Congress accepted the proposal, as they were concerned with the availability of drugs. From the early 1970s, DEA headquarters was located at 1405 I Street NW in downtown Washington, however, then–Attorney General Edwin Meese determined that the headquarters had to be located in close proximity to the Attorney Generals office. Thus, in 1989, the relocated to 600–700 Army-Navy Drive in the Pentagon City area of Arlington, Virginia. On April 19,1995, Timothy McVeigh attacked the Alfred P, security measures include hydraulic steel roadplates to enforce standoff distance from the building, metal detectors, and guard stations. In February 2003, the DEA established a Digital Evidence Laboratory within its Office of Forensic Sciences, the DEA is headed by an Administrator of Drug Enforcement appointed by the President of the United States and confirmed by the U. S. Senate. The Administrator reports to the Attorney General through the Deputy Attorney General, the Administrator is assisted by a Deputy Administrator, the Chief of Operations, the Chief Inspector, and three Assistant Administrators. Other senior staff include the financial officer and the Chief Counsel. The Administrator and Deputy Administrator are the only presidentially-appointed personnel in the DEA, DEAs headquarters is located in Arlington, Virginia across from the Pentagon. It maintains its own DEA Academy located on the United States Marine Corps base at Quantico and it maintains 21 domestic field divisions with 227 field offices and 86 foreign offices in 62 countries. With a budget exceeding 2 billion dollars, DEA employs over 10,800 people, becoming a Special Agent or Intelligence Analyst with the DEA is a competitive process. DEA agents starting salary is $49, 746–$55,483, after four years working as an agent, the salary jumps to above $92,592. Upon graduation, recruits earn themselves the title of DEA Special Agent, the DEA excludes from consideration job-applicants who have a history of any use of narcotics or illicit drugs. Investigation usually includes a polygraph test for special-agent, diversion-investigator, exceptions to this policy may be made for applicants who admit to limited youthful and experimental use of marijuana. The DEAs relatively firm stance on this issue contrasts with that of the Federal Bureau of Investigation, the DEA Aviation Division or Office of Aviation Operations is an airborne division based in Fort Worth Alliance Airport, Texas. The current OA fleet consists of 106 aircraft and 124 DEA pilots, rapid Response Teams was decommissioned by DEA Administrator Chuck Rosenburg on March 2017 via memorandum

African Great Lakes
–
The African Great Lakes are a series of lakes constituting the part of the Rift Valley lakes in and around the East African Rift. They include Lake Victoria, the second-largest fresh water lake in the world by area, and Lake Tanganyika, collectively, they contain 31,000 km3 of water, which is more than either Lake Baikal or the North American Great Lakes. This total constitutes about 25% of the planets unfrozen surface fresh water, the large rift lakes of Africa are the ancient home of great biodiversity, 10% of the worlds fish species live there. Countries in the African Great Lakes region include Burundi, the Democratic Republic of Congo, Kenya, Rwanda, Tanzania, a conference will be held on the lakes region in 2017 in Uganda. The African Great Lakes are divided among three different drainage/catchments river basins, another number also have Endorheic basin systems, such as Lake Turkana. Lake Kyoga is part of the Great Lakes system, however, it is not itself considered a Great Lake, based on size alone. Lake Tanganyika and Lake Kivu both empty into the Congo River system, while Lake Malawi is drained by the Shire River into the Zambezi, the African Great Lake region consists of countries that surround the African Great Lakes. It comprises Burundi, the Democratic Republic of Congo, Kenya, Rwanda, Tanzania, the Bantu Swahili language is the most commonly spoken language in the African Great Lakes region. It also serves as a national or official language of four nations in the region, Tanzania, Kenya, Uganda and the Democratic Republic of the Congo. Due to the population density of an estimated 107 million people, and the agricultural surplus in the region. The most powerful of these monarchies were Buganda, Bunyoro, Rwanda, unusual for sub-Saharan Africa, the traditional borders were largely maintained by the colonial powers. Being the long sought source of the Nile, the region had long been of interest to Europeans. The first Europeans to arrive in the region in any numbers were missionaries who had limited success in converting the locals, the increased contact with the rest of the world led to a series of devastating epidemics affecting both humans and livestock. While seen as a region with great potential after independence, the region has in recent decades been marred by war and conflict. According to the UNHCR, Tanzania hosted the most Congolese refugees of the region, the worst affected areas have been left in great poverty. The highlands are relatively cool, with temperatures of 17–19˚C. Major drainage basins include those of the Congo-Zaire, Nile, and Zambezi rivers, which drain into the Atlantic Ocean, Mediterranean Sea, forests are dominant in the lowlands of the Congo-Zaire Basin, while grasslands and savannas are most common in the southern and eastern highlands. Temperatures in the average about 95 °F

Shrub
–
A shrub or bush is a small to medium-sized woody plant. It is distinguished from a tree by its multiple stems and shorter height, plants of many species may grow either into shrubs or trees, depending on their growing conditions. Small, low shrubs, generally less than 2 m tall, such as lavender, periwinkle, an area of cultivated shrubs in a park or a garden is known as a shrubbery. When clipped as topiary, suitable species or varieties of shrubs develop dense foliage, many shrubs respond well to renewal pruning, in which hard cutting back to a stool results in long new stems known as canes. Other shrubs respond better to selective pruning to reveal their structure, shrubs in common garden practice are generally considered broad-leaved plants, though some smaller conifers such as mountain pine and common juniper are also shrubby in structure. Species that grow into a shrubby habit may be deciduous or evergreen
39.
Desert climate
–
An area that features this climate usually experiences from 25 to 200 mm per year of precipitation and in some years may experience no precipitation at all. Averages may be even less such as in Arica, Chile, there are usually two or three variations of a desert climate, a hot desert climate, a cold desert climate and, sometimes, a mild desert climate. To determine whether a location has a climate, the precipitation threshold is determined. If the areas precipitation is less than half the threshold. Hot desert climates are found under the subtropical ridge where there is largely unbroken sunshine for the whole year due to the stable descending air. These areas are located between 30 degrees south and 30 degrees north latitude, under the subtropical latitudes called the horse latitudes, hot desert climates are generally hot, sunny and dry year-round. Hot desert climates also reach similar latitudes in the Middle East, North Africa, hot desert climates usually feature hot, sometimes exceptionally hot, periods of the year. In many locations featuring a hot climate, maximum temperatures of over 40 °C are not uncommon in summer. The world absolute heat records, over 50 °C, are generally in the hot deserts, some desert locations consistently experience very high temperatures all year long, even during wintertime. These locations feature some of the highest annual average temperatures recorded on Earth and this last feature is seen in some parts of deserts of Africa and Arabia. During colder periods of the year, night-time temperatures can drop to freezing or below due to the radiation loss under the clear skies. However, very rarely do temperatures drop far below freezing, only one region in Europe has a hot desert climate, Province of Almeria, Province of Alicante and Province of Murcia in South Eastern Spain. Cold desert climates usually feature warm and dry summers, though summers typically are not quite as hot as summers in hot desert climates, unlike hot desert climates, cold desert climates tend to feature cold winters with rare snow. Cold desert climates are found at higher altitudes than hot desert climates. A cold desert climate is found in temperate zones, usually in the rain shadow of high mountains. A classic example of this is the Patagonian Desert in Argentina bounded by the Andes to its west, in the case of Central Asia, mountains restrict precipitation from the monsoon. The Gobi desert in Mongolia is an example of this. Though hot in summer, it shares the cold winters of the rest of Central Asia
40.
Evergreen
–
In botany, an evergreen is a plant that has leaves throughout the year, always green. This contrasts with deciduous plants, which lose their foliage during the winter or dry season. There are many different kinds of plants, both trees and shrubs. Deciduous trees shed their leaves, usually as an adaptation to a cold or dry/wet season, evergreen trees do lose leaves, but each tree loses its leaves gradually and not all at once. Most warm temperate climate plants are also evergreen, in cool temperate climates, fewer plants are evergreen, with a predominance of conifers, as few evergreen broadleaf plants can tolerate severe cold below about −30 °C. In areas where there is a reason for being deciduous, being evergreen is usually an adaptation to low nutrient levels, deciduous trees lose nutrients whenever they lose their leaves. In warmer areas, species such as pines and cypresses grow on poor soils. In Rhododendron, a genus with many broadleaf evergreens, several species grow in forests but are usually found on highly acidic soil where the nutrients are less available to plants. In taiga or boreal forests, it is too cold for the matter in the soil to decay rapidly, so the nutrients in the soil are less easily available to plants. These conditions favour the growth of more evergreens and make it difficult for deciduous plants to persist. In addition, the shelter provided by existing evergreen plants can make it easier for younger evergreen plants to survive cold and/or drought
41.
Leaf
–
A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem. The leaves and stem together form the shoot, Leaves are collectively referred to as foliage, as in autumn foliage. Although leaves can be seen in different shapes, sizes and textures, typically a leaf is a thin, dorsiventrally flattened organ, borne above ground. Most leaves have distinctive upper surface and lower surface that differ in colour, hairiness, broad, flat leaves with complex venation are known as megaphylls and the species that bear them, the majority, as broad-leaved or megaphyllous plants. In others, such as the clubmosses, with different evolutionary origins, some leaves, such as bulb scales are not above ground, and in many aquatic species the leaves are submerged in water. Succulent plants often have thick juicy leaves, but some leaves are without major photosynthetic function and may be dead at maturity, as in some cataphylls, furthermore, several kinds of leaf-like structures found in vascular plants are not totally homologous with them. Examples include flattened plant stems called phylloclades and cladodes, and flattened leaf stems called phyllodes which differ from both in their structure and origin. Many structures of plants, such as the phyllids of mosses and liverworts and even of some foliose lichens. Leaves are the most important organs of most vascular plants and these are then further processed by chemical synthesis into more complex organic molecules such as cellulose, the basic structural material in plant cell walls. The plant must therefore bring these three together in the leaf for photosynthesis to take place. Once sugar has been synthesized, it needs to be transported to areas of growth such as the plant shoots and roots. Vascular plants transport sucrose in a tissue called the phloem. The phloem and xylem are parallel to each other but the transport of materials is usually in opposite directions. Within the leaf these vascular systems branch to form veins which supply as much as the leaf as possible and they are arranged on the plant so as to expose their surfaces to light as efficiently as possible without shading each other, but there are many exceptions and complications. For instance plants adapted to windy conditions may have pendent leaves, such as in many willows, the flat, or laminar, shape also maximises thermal contact with the surrounding air, promoting cooling. Functionally, in addition to photosynthesis the leaf is the site of transpiration and guttation. Many gymnosperms have thin needle-like or scale-like leaves that can be advantageous in cold climates with frequent snow and these are interpreted as reduced from megaphyllous leaves of their Devonian ancestors. For xerophytes the major constraint is not light flux or intensity, some window plants such as Fenestraria species and some Haworthia species such as Haworthia tesselata and Haworthia truncata are examples of xerophytes. and Bulbine mesembryanthemoides
42.
Inflorescence
–
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the part of the shoot of seed plants where flowers are formed. Inflorescence can also be defined as the portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle and the major axis holding the flowers or more branches within the inflorescence is called the rachis, the stalk of each single flower is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower, any flower in an inflorescence may be referred to as a floret, especially when the individual flowers are particularly small and borne in a tight cluster, such as in a pseudanthium. The fruiting stage of an inflorescence is known as an infructescence, inflorescences may be simple or complex. The rachis may be one of several types, including Single, Composite, Umbel and these terms are general representations as plants in nature can have a combination of types. Inflorescences usually have modified shoots foliage different from the part of the plant. Considering the broadest meaning of the term, any leaf associated with an inflorescence is called a bract. A bract is usually located at the node where the stem of the inflorescence forms, joined to the main stem of the plant. They serve a variety of functions which include attracting pollinators and protecting young flowers, according to the presence or absence of bracts and their characteristics we can distinguish, Ebracteate inflorescences, No bracts in the inflorescence. Bracteate inflorescences, The bracts in the inflorescence are very specialised, sometimes reduced to small scales and this use is not technically correct, as, despite their normal appearance, these leaves are considered, in fact, bracts, so that leafy inflorescence is preferable. Leafy-bracted inflorescences, Intermediate between bracteate and leafy inflorescence, if many bracts are present and they are strictly connected to the stem, like in the family Asteraceae, the bracts might collectively be called an involucre. If the inflorescence has a unit of bracts further up the stem. Plant organs can grow according to two different schemes, namely monopodial or racemose and sympodial or cymose, the terminal bud keeps growing and forming lateral flowers. A terminal flower is never formed, the terminal bud forms a terminal flower and then dies out. Other flowers then grow from lateral buds, indeterminate and determinate inflorescences are sometimes referred to as open and closed inflorescences respectively. In an indeterminate inflorescence there is no true terminal flower and the stem usually has a rudimentary end, in many cases the last true flower formed by the terminal bud straightens up, appearing to be a terminal flower
