Denmark
–
The term Danish Realm refers to the relationship between Denmark proper, the Faroe Islands and Greenland—three countries constituting the Kingdom of Denmark. The legal nature of the Kingdom of Denmark is fundamentally one of a sovereign state. The Faroe Islands and Greenland have been part of the Crown of Denmark since 1397 when the Kalmar Union was ratified, legal matters in The Danish Realm are subject to the Danish Constitution. Beginning in 1953, state law issues within The Danish Realm has been governed by The Unity of the Realm, a less formal name for The Unity of the Realm is the Commonwealth of the Realm. In 1978, The Unity of The Realm was for the first time referred to as rigsfællesskabet. The name caught on and since the 1990s, both The Unity of The Realm and The Danish Realm itself has increasingly been referred to as simply rigsfællesskabet in daily parlance. The Danish Constitution stipulates that the foreign and security interests for all parts of the Danish Realm are the responsibility of the Danish government, the Faroes received home rule in 1948 and Greenland did so in 1979. In 2005, the Faroes received a self-government arrangement, and in 2009 Greenland received self rule, the Danish Realms unique state of internal affairs is acted out in the principle of The Unity of the Realm. This principle is derived from Article 1 of the Danish Constitution which specifies that constitutional law applies equally to all areas of the Danish Realm, the Constitutional Act specifies that sovereignty is to continue to be exclusively with the authorities of the Realm. The language of Denmark is Danish, and the Danish state authorities are based in Denmark, the Kingdom of Denmarks parliament, with its 179 members, is located in the capital, Copenhagen. Two of the members are elected in each of Greenland and the Faroe Islands. The Government ministries are located in Copenhagen, as is the highest court, in principle, the Danish Realm constitutes a unified sovereign state, with equal status between its constituent parts. Devolution differs from federalism in that the powers of the subnational authority ultimately reside in central government. The Self-Government Arrangements devolves political competence and responsibility from the Danish political authorities to the Faroese, the Faroese and Greenlandic authorities administer the tasks taken over from the state, enact legislation in these specific fields and have the economic responsibility for solving these tasks. The Danish government provides a grant to the Faroese and the Greenlandic authorities to cover the costs of these devolved areas. The 1948 Home Rule Act of the Faroe Islands sets out the terms of Faroese home rule, the Act states. the Faroe Islands shall constitute a self-governing community within the State of Denmark. It establishes the government of the Faroe Islands and the Faroese parliament. The Faroe Islands were previously administered as a Danish county, the Home Rule Act abolished the post of Amtmand and these powers were expanded in a 2005 Act, which named the Faroese home government as an equal partner with the Danish government

Television
–
Television or TV is a telecommunication medium used for transmitting moving images in monochrome, or in color, and in two or three dimensions and sound. The term can refer to a set, a television program. Television is a medium for entertainment, education, news, politics, gossip. Television became available in experimental forms in the late 1920s. After World War II, a form of black-and-white TV broadcasting became popular in the United States and Britain, and television sets became commonplace in homes, businesses. During the 1950s, television was the medium for influencing public opinion. In the mid-1960s, color broadcasting was introduced in the US, for many reasons, the storage of television and video programming now occurs on the cloud. At the end of the first decade of the 2000s, digital television transmissions greatly increased in popularity, another development was the move from standard-definition television to high-definition television, which provides a resolution that is substantially higher. HDTV may be transmitted in various formats, 1080p, 1080i, in 2013, 79% of the worlds households owned a television set. Most TV sets sold in the 2000s were flat-panel, mainly LEDs, major manufacturers announced the discontinuation of CRT, DLP, plasma, and even fluorescent-backlit LCDs by the mid-2010s. In the near future, LEDs are gradually expected to be replaced by OLEDs, also, major manufacturers have announced that they will increasingly produce smart TVs in the mid-2010s. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s, Television signals were initially distributed only as terrestrial television using high-powered radio-frequency transmitters to broadcast the signal to individual television receivers. Alternatively television signals are distributed by cable or optical fiber, satellite systems and. Until the early 2000s, these were transmitted as analog signals, a standard television set is composed of multiple internal electronic circuits, including a tuner for receiving and decoding broadcast signals. A visual display device which lacks a tuner is correctly called a video monitor rather than a television, the word television comes from Ancient Greek τῆλε, meaning far, and Latin visio, meaning sight. The Anglicised version of the term is first attested in 1907 and it was. formed in English or borrowed from French télévision. In the 19th century and early 20th century, other. proposals for the name of a technology for sending pictures over distance were telephote. The abbreviation TV is from 1948, the use of the term to mean a television set dates from 1941

Film
–
A film, also called a movie, motion picture, theatrical film or photoplay, is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession, the process of filmmaking is both an art and an industry. The word cinema, short for cinematography, is used to refer to the industry of films. Films were originally recorded onto plastic film through a photochemical process, the adoption of CGI-based special effects led to the use of digital intermediates. Most contemporary films are now fully digital through the process of production, distribution. Films recorded in a form traditionally included an analogous optical soundtrack. It runs along a portion of the film exclusively reserved for it and is not projected, Films are cultural artifacts created by specific cultures. They reflect those cultures, and, in turn, affect them, Film is considered to be an important art form, a source of popular entertainment, and a powerful medium for educating—or indoctrinating—citizens. The visual basis of film gives it a power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles to translate the dialog into the language of the viewer, some have criticized the film industrys glorification of violence and its potentially negative treatment of women. The individual images that make up a film are called frames, the perception of motion is due to a psychological effect called phi phenomenon. The name film originates from the fact that film has historically been the medium for recording and displaying motion pictures. Many other terms exist for a motion picture, including picture, picture show, moving picture, photoplay. The most common term in the United States is movie, while in Europe film is preferred. Terms for the field, in general, include the big screen, the screen, the movies, and cinema. In early years, the sheet was sometimes used instead of screen. Preceding film in origin by thousands of years, early plays and dances had elements common to film, scripts, sets, costumes, production, direction, actors, audiences, storyboards, much terminology later used in film theory and criticism apply, such as mise en scène. Owing to the lack of any technology for doing so, the moving images, the magic lantern, probably created by Christiaan Huygens in the 1650s, could be used to project animation, which was achieved by various types of mechanical slides

Neurosurgery
–
In different countries, there are different requirements for an individual to legally practice neurosurgery, and there are varying methods through which they must be educated. In most countries, neurosurgeon training requires a period of seven years after graduating from medical school. In the United States, a neurosurgeon must generally complete four years of education, four years of medical school. Most, but not all, residency programs have some component of science or clinical research. Neurosurgeons may pursue training in the form of a fellowship, after residency or in some cases. In the U. S. neurosurgery is considered a highly competitive specialty composed of 0. 6% of all practicing physicians, in the United Kingdom, students must gain entry into medical school. MBBS qualification takes four to six years depending on the students route, junior doctors then apply to enter the neurosurgical pathway. Neurosurgery remains consistently amongst the most competitive specialties in which to obtain entry. The Incas appear to have practiced a procedure known as trepanation since the late Stone age, during the Middle Ages in Arabia from 936 to 1013 AD, Al-Zahrawi performed surgical treatments of head injuries, skull fractures, spinal injuries, hydrocephalus, subdural effusions and headache. There was not much advancement in neurosurgery until late 19th early 20th century, history of electrodes in the brain, In 1878 Richard Canton discovered that electrical signals transmitted through an animals brain. In 1950 Dr. Jose Delgado invented the first electrode that was implanted in a brain, using it to make it run. In 1972 the cochlear implant, a neurological prosthetic that allowed people to hear was marketed for commercial use. In 1998 researcher Philip Kennedy implanted the first Brain Computer Interface into a human subject, history of tumor removal, In 1879 after locating it via neurological signs alone, Scottish surgeon William Macewen performed the first successful brain tumor removal. On March 16,1907 Austrian surgeon Hermann Schloffer became the first to remove a pituitary tumor. The main advancements in neurosurgery came about as a result of highly crafted tools, modern neurosurgical tools, or instruments, include chisels, curettes, dissectors, distractors, elevators, forcepts, hooks, impactors, probes, suction tubes, power tools, and robots. Most of these tools, like chisels, elevators, forcepts, hooks, impactors. The main difference of these tools, pre and post advancement in neurosurgery, were the precision in which they were crafted and these tools are crafted with edges that are within a millimeter of desired accuracy. Other tools such as hand held power saws and robots have only recently been used inside of a neurological operating room

After suffering from the effects of plague and fire in the 18th century and this included construction of the prestigious district of Frederiksstaden and founding of such cultural institutions as the Royal Theatre and the Royal Academy of Fine Arts. Later, following the Second World War, the Finger Plan fostered the development of housing, since the turn of the 21st century, Copenhagen has seen strong urban and cultural development, facilitated by investment in its institutions and infrastructure. The city is the cultural, economic and governmental centre of Denmark, Copenhagens economy has seen rapid developments in the service sector, especially through initiatives in information technology, pharmaceuticals and clean technology. Since the completion of the Øresund Bridge, Copenhagen has become integrated with the Swedish province of Scania and its largest city, Malmö.

Rigshospitalet
–
Rigshospitalet is one of the largest hospitals in Denmark and the most highly specialised hospital in Copenhagen. The hospitals main building is a 16 storey functionalist highrise, one of the tallest structures in the parts of the city. Rigshospitalet neighbours the Panum Building which houses the Faculty of Health, as a teaching hospital it is part of the framework organisation Copenhagen University Hospital. The Danish name is not usually translated to English and it is the genitive of rige and the cognate word is used similarly in Norwegian, Swedish, Icelandic and Dutch. The prefix Stats- is more used, but implies a slightly lower level in the hierarchy. Although Rigshospitalet was founded as a hospital, as opposed to the normal hospitals operated by counties. The hospital itself explains the name was given because its predecessor, Royal Fredericks Hospital, was handed over to the state, Rigshospitalet was founded on 30 March 1757 as Kongelig Frederiks Hospital, named after King Frederick V and situated in Bredgade in central Copenhagen. The buildings are now occupied by the Danish Museum of Art & Design, since 1903 the state has been the owner of the hospital. In 1910 the hospital was renamed and moved to its present location in ten low buildings surrounding a garden designed by architect Martin Borch. In 1995 the hospital was handed over to Hovedstadens Sygehusfællesskab which in 2007 was absorbed by the Capital Region, in 2007 a helipad was built on top of the hospital. Until then, rescue helicopters and helicopters transferring patients would land in the neighbouring park Fælledparken, rigshospitalets mission is to be Denmarks leading hospital for patients needing highly specialized treatment. Its main specialist role has been enhanced in recent years by the decision that it should serve as the host institution for many of Copenhagens speciality departments, because of this, other hospitals refer patients to Rigshospitalet for the unique expertise available there. Rigshospitalet’s neighbor, the Panum Building, houses the University of Copenhagens Faculty of Health and this proximity optimizes a close cooperation between the two in the fields of research and development. The Nordic Cochrane Centre and the University Centre for Nursing and Care Research are in Rigshospitalet, with 1,120 beds, Rigshospitalet has responsibility for 65,000 inpatients and approximately 420,000 outpatients annually. Rigshospitalet has a trauma centre specialised at receiving severely injured patients, ordinary emergency department treatment has been relegated to the other hospitals in Copenhagen. The hospital was the location of Lars von Triers television horror mini-series The Kingdom and it is the hospital in which Crown Princess Mary gave birth to her four children by Crown Prince Frederik, Christian, Isabella, Vincent, and Josephine. Also Prince Joachims children were born here, Nikolai, Felix, Henrik, queen Margrethe and Prince Henriks children, Crown Prince Frederik and Prince Joachim, were born at Rigshospitalet. Prince Carl Fredrik and Princess Nathalie of Sayn-Wittgenstein-Berleburgs third child and second son, Prince Frederik, in 2007 Rigshospitalet celebrated its 250th anniversary

Hospital
–
A hospital is a health care institution providing patient treatment with specialized medical and nursing staff and medical equipment. The best-known type of hospital is the hospital, which typically has an emergency department to treat urgent health problems ranging from fire. A district hospital typically is the health care facility in its region, with large numbers of beds for intensive care. Specialised hospitals can help reduce health care costs compared to general hospitals, a teaching hospital combines assistance to people with teaching to medical students and nurses. The medical facility smaller than a hospital is called a clinic. Hospitals have a range of departments and specialist units such as cardiology, some hospitals have outpatient departments and some have chronic treatment units. Common support units include a pharmacy, pathology, and radiology, Hospitals are usually funded by the public sector, by health organisations, by health insurance companies, or by charities, including direct charitable donations. Historically, hospitals were founded and funded by religious orders, or by charitable individuals. During the Middle Ages, hospitals served different functions from modern institutions, Middle Ages hospitals were almshouses for the poor, hostels for pilgrims, or hospital schools. The word hospital comes from the Latin hospes, signifying a stranger or foreigner, another noun derived from this, hospitium came to signify hospitality, that is the relation between guest and shelterer, hospitality, friendliness, and hospitable reception. By metonymy the Latin word then came to mean a guest-chamber, guests lodging, hospes is thus the root for the English words host hospitality, hospice, hostel and hotel. The German word Spital shares similar roots, the grammar of the word differs slightly depending on the dialect. Some patients go to a hospital just for diagnosis, treatment, or therapy and then leave without staying overnight, while others are admitted and stay overnight or for several days or weeks or months. Hospitals usually are distinguished from other types of facilities by their ability to admit and care for inpatients whilst the others. Larger cities may have several hospitals of varying sizes and facilities, some hospitals, especially in the United States and Canada, have their own ambulance service. A district hospital typically is the health care facility in its region, with large numbers of beds for intensive care. In California, district hospital refers specifically to a class of healthcare facility created shortly after World War II to address a shortage of beds in many local communities. Twenty-eight of Californias rural hospitals and 20 of its critical-access hospitals are District hospitals, Californias District hospitals are formed by local municipalities, have Boards that are individually elected by their local communities, and exist to serve local needs

Photographic print toning
–
In photography, toning is a method of changing the color of black-and-white photographs. In analog photography, it is a process carried out on silver-based photographic prints. This darkroom process cannot be performed with a color photograph, the effects of this process can be emulated with software in digital photography. Most toners work by replacing the silver in the emulsion with a silver compound. The compound may be more stable than silver and may also have a different color or tone. Different toning processes give different colors to the final print, in some cases, the printer may choose to tone some parts of a print more than others. Toner also can increase the range of shades visible in a print without reducing the contrast, selenium toning is especially effective in this regard. Some toning processes can improve the stability of the print. Other toning processes, such as those including iron and copper, many chemical toners are highly toxic, some even containing chemicals that are carcinogenic. It is therefore important that the chemicals be used in a well ventilated area. Selenium toning is a popular archival toning process, converting metallic silver to silver selenide, in a diluted toning solution, selenium toning gives a red-brown tone, while a strong solution gives a purple-brown tone. The change in color depends upon the chemical make-up of the photographic emulsion being toned, chloro-bromide papers change dramatically, whilst pure bromide papers change little. Fibre-based papers are more responsive to selenium toning, selenium toning may not produce prints quite as stable as sepia or gold toning. Recently, doubts have surfaced as to the effectiveness of selenium toner in ensuring print longevity, in most applications, selenium toning was not used for its sepia or red tone by fine art photographers. In fact it was used for the opposite of those effects Agfa Portriga Rapid, depending on the strength of selenium tone mixed in water, a three- to four-minute tray bath, with continuous circulation, removed the brownish green tone and provided a deep rich black. Higher concentrations of selenium toning and longer tray baths produced the red effect, 99% of selenium-toned vintage prints in museums and sold at galleries and auction are toned to remove the brownish green tone and provided a deep rich black. Most reported tests over the years in technical photography publications gave selenium-toned prints twice the longevity of untoned prints, sepia toning is a specialized treatment to give a black-and-white photographic print a warmer tone and to enhance its archival qualities. The metallic silver in the print is converted to a sulfide compound, silver sulfide is at least 50% more stable than silver

Spiritualism
–
Spiritualism is the belief that the spirits of the dead have both the ability and the inclination to communicate with the living. The afterlife, or the world, is seen by spiritualists, not as a static place. Some spiritualists will speak of a concept which they refer to as spirit guides—specific spirits, often contacted, Spiritism, a branch of spiritualism developed by Allan Kardec and today practiced mostly in Continental Europe and Latin America, especially in Brazil, emphasizes reincarnation. Spiritualism developed and reached its peak growth in membership from the 1840s to the 1920s, by 1897, spiritualism was said to have more than eight million followers in the United States and Europe, mostly drawn from the middle and upper classes. Many prominent spiritualists were women, and like most spiritualists, supported such as the abolition of slavery. By the late 1880s the credibility of the movement had weakened due to accusations of fraud perpetrated by mediums. Spiritualism is currently practiced primarily through various denominational spiritualist churches in the United States, Canada and they believe that spirit mediums are gifted to carry on such communication, but that anyone may become a medium through study and practice. They believe that spirits are capable of growth and perfection, progressing through higher spheres or planes, and that the afterlife is not a static state, many believers therefore speak of spirit guides—specific spirits, often contacted, and relied upon for worldly and spiritual guidance. According to spiritualists, anyone may receive messages, but formal communication sessions are held by mediums. Nevertheless, on significant points Christian Protestantism and spiritualism are different and this view is self-evidently incompatible with spiritualism, where the merely spiritual existence is superior to the embodied one. There are quite a number of spiritualist churches which are explicitly Christian in theology, forms of worship and praise, judaism It is held by some adherents of the Jewish religion that spiritualism is strictly forbidden by the Bible. Islam Within Islam, only rarely do some traditions - notably Sufism, despite this, the majority of the followers of Islam believe in the existence of spirits as a fundamental aspect of their religion. However, these spirits are not those of humans but of a third sapient creation said to be made by God called the jinn. Jinn are spirits made from fire, in a realm not visible to the eyes of people. A famous jinn in the Muslim tradition is Satan, as opposed to the Christian belief that he is a fallen angel, communication with these spirits, whether the spirit is good or evil in nature, is generally not encouraged in Islam. Additionally, the concept of Tawassul recognises the existence of spirits on a higher plane of existence closer to God. Spiritism Spiritism, the branch of spiritualism developed by Allan Kardec, Occultism Spiritualism also differs from occult movements, such as the Hermetic Order of the Golden Dawn or the contemporary wiccan covens, in that spirits are not contacted to obtain magical powers. Eliphas Lévi, who is regarded as the founder of occultism, strongly rejected Spiritism, later on, Madame Blavatsky, the founder of the Theosophical Society, only practiced mediumship to contact powerful spirits capable of conferring esoteric knowledge

Elevator
–
An elevator or lift is a type of vertical transportation that moves people or goods between floors of a building, vessel, or other structure. Elevators are generally powered by electric motors that either drive traction cables or counterweight systems like a hoist, in agriculture and manufacturing, an elevator is any type of conveyor device used to lift materials in a continuous stream into bins or silos. Several types exist, such as the chain and bucket elevator, grain auger screw conveyor using the principle of Archimedes screw, or the chain, languages other than English may have loanwords based on either elevator or lift. Because of wheelchair access laws, elevators are often a requirement in new multistory buildings. The earliest known reference to an elevator is in the works of the Roman architect Vitruvius, some sources from later historical periods mention elevators as cabs on a hemp rope powered by hand or by animals. In 1000, the Book of Secrets by al-Muradi in Islamic Spain described the use of a lifting device. In the 17th century the prototypes of elevators were located in the buildings of England. Louis XV of France had a flying chair built for one of his mistresses at the Chateau de Versailles in 1743. Ancient and medieval elevators used drive systems based on hoists or winders, the invention of a system based on the screw drive was perhaps the most important step in elevator technology since ancient times, leading to the creation of modern passenger elevators. The first screw drive elevator was built by Ivan Kulibin and installed in Winter Palace in 1793, several years later another of Kulibins elevators was installed in Arkhangelskoye near Moscow. The development of elevators was led by the need for movement of raw materials including coal, the technology developed by these industries and the introduction of steel beam construction worked together to provide the passenger and freight elevators in use today. Starting in the mines, by the mid-19th century elevators were operated with steam power and were used for moving goods in bulk in mines and factories. It elevated paying customers to a height in the center of London. Early, crude steam-driven elevators were refined in the decade, – in 1835 an innovative elevator called the Teagle was developed by the company Frost. The elevator was belt-driven and used a counterweight for extra power, the hydraulic crane was invented by Sir William Armstrong in 1846, primarily for use at the Tyneside docks for loading cargo. These quickly supplanted the steam driven elevators, exploiting Pascals law. A water pump supplied a variable level of pressure to a plunger encased inside a vertical cylinder. Counterweights and balances were used to increase the lifting power of the apparatus
