True flies are insects of the order Diptera, the name being derived from the Greek δι- di- "two", πτερόν pteron "wings". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, mouthparts designed for piercing and sucking, or for lapping and sucking in the other groups, their wing arrangement gives them great maneuverability in flight, claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the pupa is a tough capsule. Diptera is one of the major insect orders and of considerable human importance. Flies are important pollinators, second only to their Hymenopteran relatives.

Flies may have been among the evolutionarily earliest pollinators responsible for early plant pollination. Fruit flies are used as model organisms in research, but less benignly, mosquitoes are vectors for malaria, West Nile fever, yellow fever and other infectious diseases. Flies can be annoyances in some parts of the world where they can occur in large numbers and settling on the skin or eyes to bite or seek fluids. Larger flies such as tsetse flies and screwworms cause significant economic harm to cattle. Blowfly larvae, known as gentles, other dipteran larvae, known more as maggots, are used as fishing bait and as food for carnivorous animals, they are used in medicine in debridement to clean wounds. Dipterans are insects that undergo radical metamorphosis, they belong to the Mecopterida, alongside the Mecoptera, Siphonaptera and Trichoptera. The possession of a single pair of wings distinguishes most true flies from other insects with "fly" in their names. However, some true flies such as Hippoboscidae have become secondarily wingless.

The cladogram represents the current consensus view. The first true dipterans known are from the Middle Triassic, they became widespread during the Middle and Late Triassic. Modern flowering plants did not appear until the Cretaceous, so the original dipterans must have had a different source of nutrition other than nectar. Based on the attraction of many modern fly groups to shiny droplets, it has been suggested that they may have fed on honeydew produced by sap-sucking bugs which were abundant at the time, dipteran mouthparts are well-adapted to softening and lapping up the crusted residues; the basal clades in the Diptera include the enigmatic Nymphomyiidae. Three episodes of evolutionary radiation are thought to have occurred based on the fossil record. Many new species of lower Diptera developed in the Triassic, about 220 million years ago. Many lower Brachycera appeared in the Jurassic, some 180 million years ago. A third radiation took place among the Schizophora at the start of the Paleogene, 66 million years ago.

The phylogenetic position of Diptera has been controversial. The monophyly of holometabolous insects has long been accepted, with the main orders being established as Lepidoptera, Coleoptera and Diptera, it is the relationships between these groups which has caused difficulties. Diptera is thought to be a member of Mecopterida, along with Lepidoptera, Siphonaptera and Strepsiptera. Diptera has been grouped with Siphonaptera and Mecoptera in the Antliophora, but this has not been confirmed by molecular studies. Diptera were traditionally broken down into two suborders and Brachycera, distinguished by the differences in antennae; the Nematocera are identified by their elongated bodies and many-segmented feathery antennae as represented by mosquitoes and crane flies. The Brachycera have much shorter antennae. Subsequent studies have identified the Nematocera as being non-monophyletic with modern phylogenies placing the Brachycera within grades of groups placed in the Nematocera; the construction of a phylogenetic tree has been the subject of ongoing research.

The following cladogram is based on the FLYTREE project. Abbreviations used in the cladogram: Cal=Calyptratae Cyc=Cyclorrhapha Ere=Eremoneura Mus=Muscomorpha Sch=Schizophora Tab=Tabanomorpha Flies are abundant and are found in all terrestrial habitats in the world apart from Antarctica, they include many familiar insects such as house flies, blow flies, gnats, black flies and fruit flies. More than 150,000 have been formally described and the actual species diversity is much greater, with the flies from many parts of the world yet to be studied intensively; the suborder Nematocera include small, slender insects with long antennae such as mosquitoes, gnats and crane-flies, while the Brachycera includes broader, more robust flies with short antennae. Many nematoceran larvae are aquatic. There are estimated to be a total of about 19,000 species of Diptera in Europe, 22,000 in the Nearctic region, 20,0

Roeselare–Leie Canal

The Roeselare–Leie Canal is an artificial waterway between the town Roeselare and the river Leie in West Flanders, Belgium. The canal is 16.5 kilometres long and was dug in 10 years between 1862 and 1872. The employment grew and ships with a carrying capacity of 600 tonnes brought grain and other basic products to the factories around the canal; the port of Roeselare, at the start of the Roeselare–Leie Canal, is characterized by a thriving industrial activity. Well-known companies that are located there include Hendrix and Debaillie, both producers of animal food. Soubry, the well-known dough manufacturer has an establishment there; the Roeselare port covers an area of 40 hectares and is accessible by road. Nearby is the A17/E403 highway Bruges-Kortrijk with many opportunities to explore the coast, the inland or the Belgian-French and Belgian-Dutch border regions; the disclosure in Roeselare is good with the Mandel Avenue that can be used to access the industrial zone in Beveren. It is easy to choose driving through the King Albert I Avenue until the inner ring road to the outer ring road N36/R32.

The canal connects Roeselare with the ports of Dunkirk, Antwerp and Liege, via the Leie. Following the canal from Roeselare City, one passes first the town of Izegem where the food company Vandemoortele Groep is located Ingelmunster and Oostrozebeke, Ooigem, a municipality of Wielsbeke where the canal joins the Leie. There is a lock to overcome a height of 7.50 meters. The Kortrijk-Bruges railway line runs a few kilometers parallel to the canal that can handle barges up to 1350 tonnes. There is a proposal to build a container terminal for temporary container storage alongside the canal; the Leiestreek tourist office and the municipality are working on a project to give the canal and the green area around it a recreational function. For example, during the summer there are boat cruises; the banks of the canal are frequented by fishermen. The piece of the canal between Roeselare port and the town is an ideal backdrop for street theater and cultural events, such as the happening "De Groote Stooringe".

The ‘Zwaaikom’ in Roeselare is a turn in the canal. This widening makes. Nowadays there is a lot of industry in that neighbourhood and no inhabitation; the big roundabout is important for easy freight-traffic on the road. At this roundabout, there is a building for recreation near by the water-side where you can rent a kayak; this article is based on the Dutch article "Kanaal Roeselare-Leie"

Power trio

A power trio is a rock and roll band format having a lineup of electric guitar, bass guitar and drum kit, leaving out the second rhythm guitar or keyboard instrument that are used in other rock music bands that are quartets and quintets. Larger rock bands use one or more additional rhythm section to fill out the sound with chords and harmony parts. Most power trios in hard rock and heavy metal music use the electric guitar player in two roles. While one or more band members sing while they play their instruments, power trios in hard rock and heavy metal music emphasize instrumental performance and overall sonic impact over vocals and lyrics. An example of a power trio is Motörhead, which consisted of a bassist and drummer, with Lemmy, the bass guitarist, singing lead vocals while he played bass; the rise of the power trio in the 1960s was made possible in part by developments in amplifier technology that enhanced the volume of the electric guitar and bass. The popularization of the electric bass guitar defined the bottom end and filled in the gaps.

Since the amplified bass could now be louder, the rest of the band could play at higher volumes, without fear of being unable to hear the bass. This allowed a three-person band to have the same sonic impact as a large band but left far more room for improvisation and creativity, unencumbered by the need for detailed arrangements; as with the organ trio, a 1960s-era soul jazz group centered on the amplified Hammond organ, a three-piece group could fill a large bar or club with a big sound for a much lower price than a large rock and roll band. A power trio, at least in its blues rock incarnation, is generally held to have developed out of Chicago-style blues bands such as Muddy Waters' trio. In addition to technological improvements, another impetus for the rise of the power trio was the virtuosity of guitarists such as Eric Clapton, Jimi Hendrix, Rory Gallagher, who could cover both the rhythm guitar and lead guitar roles in a live performance. In 1964, Frank Zappa played guitar in a power trio the Muthers, with Paul Woods on bass and Les Papp on drums.

In 1966, the prototypical blues-rock power trio Cream was formed, consisting of Eric Clapton on guitar/vocals, Jack Bruce on bass/vocals, Ginger Baker on drums. Other influential 1960s-era blues rock/hard rock power trio bands were the Jimi Hendrix Experience, Blue Cheer, Grand Funk Railroad, the James Gang featuring Joe Walsh, Taste. Well-known 1970s-era power trios include the Canadian progressive rock groups Rush and Triumph, the American band ZZ Top, the British heavy metal band Motörhead, Robin Trower. Emerson, Lake & Palmer, while replacing the guitarist by a keyboardist, is considered as a power trio, as Keith Emerson fulfilled the rhythm and lead playing on the keyboards that would fall on the guitarist, while bassist Greg Lake was the vocalist. In 1968, the power trio Manal was formed in Argentina, were the first group that composed blues music in Spanish. After the 1970s, the phrase "power trio" was applied to the new wave group the Police, grunge band Nirvana, post-punk band Hüsker Dü, mod revivalists the Jam, hard rock/progressive metal band King's X, progressive rock band Rush, post-grunge band Silverchair, alternative bands the Presidents of the United States of America, Goo Goo Dolls, Everclear and Eve 6, pop punk bands such as Green Day, Blink-182, Alkaline Trio and MxPx, Argentine rock bands like Soda Stereo and From Power Project.

By the 1990s, rock trios began to form around different instrumentation, from the band Morphine, featuring a baritone saxophone instead of an electric guitar, to Ben Folds Five's replacing the guitar with various keyboards, principally the piano.

The Leopard (Reid novel)

The Leopard is a novel by Jamaican writer, V. S. Reid, it portrays the hardships of the Kenyan people during the time of the Mau Mau Rebellion. Novels similar to The Leopard, such as Caroline Elkins’s Imperial Reckoning, as well as Ngũgĩ wa Thiong'o’s Petals of Blood reflect events during the Mau Mau uprising; the Leopard, distinct from any other novel of its kind focuses on the controversies of human nature with respect to the co-existence of violence and hatred between Africans and Europeans. Published in 1958, The Leopard, Victor Reid’s second novel, marks a shift from his earlier concerns of illustrating struggles in Jamaica to illustrating a symbolic similarity in Africa; the title is representative of the character in the novel that symbolizes a blend of the counteracting white and black tendencies. The novel begins when the main character Nebu, a Kikuyu tribe member, leaves his Mau Mau people to hunt down a white man, traveling in the African bush. After catching up to the white man who has brought his son along, Nebu throws a spear at the white man and kills him while the white man shoots at Nebu, injuring his side.

After killing the white man, Nebu realizes that it was an English planter. As a result of committing this crime, Nebu feels obligated to repay the boss, for having slept with his white wife. For this reason, he decides to safeguard the boss’ child, in truth, biologically his own, return him to a white community; the decision to bring the child to a white community is a tough one for him, for he is himself injured from the bullet, the child is incapable of walking alone, making the journey twice as difficult. As Nebu carries his son through the bush, the boy, raised with mixed emotions towards blacks and whites, continually taunts him. While they travel, they together become watched by the leopard, which plots to kill the two concurrently. Nebu’s wound from the bullet continuously weakens him, making him more susceptible to attack from the leopard. At this point, the leopard attacks and brings a tragic ending to the “twisted little cripple’s” life. Before Nebu could spear the leopard, an English army lieutenant shoots at the leopard, killing it instantly.

Reid set his novel in Africa instead of Jamaica to connect the struggle of the African people, which are the true origins of the black Jamaicans, to the oppression of the Jamaican people. Critic Kenneth Ramchand once said, “The West Indian Negro is a descendent of the Africans, more the idea of Africa has been a phase of West-Indian political thinking.”Upon analysis of The Leopard, Ramchand posed a point of contention as to why the beautiful poetry of the novel included so much violence, why the violence is discussed in such “loving terms.” Ramchand concluded that this clash was intended to make the reader aware of the “savage, twisted inhumanity of the men” in the novel. This indicates that Reid most used many subtleties to depict specific situations throughout his novels. For instance, throughout the course of the novel, Reid associates animalism with whites in order to dehumanize them; the most important symbol, the leopard, is significant in its literal sense as well as a deeper one. The leopard’s role as a representation of cowardliness is evident when “the leopard understands it, for he avoids the strong and eats the weak.”Reid emphasizes the differing tendencies of the blacks and whites attempting to coexist.

Throughout the novel, critic Mervyn Morris notes that the blacks are portrayed as being in accordance with nature while the whites are “man made.” They each, strive to gain the advantages of the opposing people-, to say that blacks desire many “white powers” of which they are deprived while whites desire the advantages of being natives of African territories. Furthermore, the relationship between Nebu and his son constitutes, according to Morris, the heart of the novel. Morris contends that Reid employs the son as a symbol of the cultures produced by a meeting of black and white civilizations; this characteristic signifies the love and hate dynamic between groups as well as between individuals
