Agkistrodon piscivorus is a venomous snake, a species of pit viper, found in the southeastern United States. Adults are large and capable of delivering a painful and potentially fatal bite. When antagonized, they will stand their ground by coiling their bodies and displaying their fangs. Although their aggression has been exaggerated, individuals may bite when feeling threatened or being handled. This is the world's only semiaquatic viper, usually found in or near water, particularly in slow-moving and shallow lakes, streams, and marshes. The snake is a strong swimmer and will even enter the sea. It has successfully colonized islands off both the Atlantic and Gulf coasts.
The generic name is derived from the Greek words ancistro (hooked) and odon (tooth), and the specific name comes from the Latinpiscis (fish) and voro (to eat); thus, the scientific name translates into “hooked-tooth fish-eater”. Common names include variants on water moccasin, swamp moccasin, black moccasin, cottonmouth, gapper, or simply viper. Many of the common names refer to the threat display, where this species will often stand its ground and gape at an intruder, exposing the white lining of its mouth. Three subspecies are currently recognized, including the nominate subspecies described here. Its diet consists mainly of fish and frogs but is otherwise highly varied and, uniquely, has even been reported to include carrion.
The Congo River (also known as the Zaire River; French:(le) fleuve Congo/Zaïre; Portuguese:rio Congo/Zaire) is a river in Africa. It is the second largest river in the world by discharge (after the Amazon), and the world's deepest river with measured depths in excess of 220m (720ft).
The Congo-Chambeshi river has an overall length of 4,700km (2,920mi), which makes it the ninth longest river (in terms of discharge, the Chambeshi is a tributary of the Lualaba River, Lualaba being the name of the Congo River upstream of the Boyoma Falls, extending for 1,800km).
Measured along the Lualaba, the Congo River has a total length of 4,370km (2,715mi). It crosses the equator twice.
The Congo Basin has a total area of about 4 million km2, or 13% of the entire African landmass.
The River Congo got its name from the Kingdom of Kongo which was situated on the left banks of the river estuary. The kingdom is in turn named for its Bantu population, in the 17th century reported as Esikongo. South of the Kongo kingdom proper lay the similarly named Kakongo kingdom, mentioned in 1535.
Abraham Ortelius in his world map of 1564 labels as Manicongo the city at the mouth of the river.
The tribal names in kongo possibly derive from a word for a public gathering or tribal assembly.
Electrical work is the work done on a charged particle by an electric field. The equation for 'electrical' work is equivalent to that of 'mechanical' work:
The electrical work per unit of charge, when moving a negligible test charge between two points, is defined as the voltage between those points.
Particles that are free to move, if positively charged, normally tend towards regions of lower voltage (net negative charge), while if negatively charged they tend to shift towards regions of higher voltage (net positive charge).
However, any movement of a positive charge into a region of higher voltage requires external work to be done against the field of the electric force, work equal to that electric field would do in moving that positive charge the same distance in the opposite direction. Similarly, it requires positive external work to transfer a negatively charged particle from a region of higher voltage to a region of lower voltage.
The electric force is a conservative force: work done by a static electric field is independent of the path taken by the charge. There is no change in the voltage (electric potential) around any closed path; when returning to the starting point in a closed path, the net of the external work done is zero. The same holds for electric fields.
A work of art, artwork, art piece, piece of art or art object is an aestheticphysical item or artistic creation. Apart from "work of art", which may be used of any work regarded as art in its widest sense, including works from literature and music, these terms apply principally to tangible, portable forms of visual art:
"Work" is a song recorded by Barbadian singer Rihanna for her eighth studio album, Anti (2016). The song features a verse by Canadian rapper Drake. The artists co-wrote the single with PartyNextDoor, Allen Ritter, Rupert Thomas, R. Stephenson, Monte Moir, and Boi-1da; the latter is also the producer.
Upon its release, "Work" received mixed reviews from music critics. The song debuted at number nine and has so far peaked at number seven on the Billboard Hot 100, becoming Rihanna's 27th and Drake's 15th top ten entry on the chart. It has also peaked within the top ten of the charts in Australia, Canada, France, Hungary, Spain, and the United Kingdom.
Writing and development
"Work" was written by the artists, PartyNextDoor, Allen Ritter, Rupert "Sevn" Thomas, Monte Moir, R. Stephenson, and Boi-1da; the latter is also the producer. In the summer of 2015, Thomas, Ritter, Boi-1da and Martin Mason among others, stayed at Drake house in Los Angeles for a mid-week period. Thomas described the time spent at the home as a "beat factory, everyone was sitting there working and collaborating with each other."
Thomas created a beat which was dancehall-influenced; he later played it for Boi-1da to which he positively responded, "We’re both Jamaican-Canadian. It was just something in our DNA, so it woke him up, and we started remembering all these old dancehall songs from the '90s." Boi-1da came with up idea for sampling an "old school dancehall rhythm" and after that the chords were made with Ritter and past it, "everything went organically".
