Gerrit De Veer
Gerrit de Veer (–) was a Dutch officer on Willem Barentsz' second and third voyages of 1595 and 1596 respectively, in search of the Northeast passage. De Veer kept a diary of the voyages and in 1597, was the first person to observe and record the Novaya Zemlya effect, and the first Westerner to observe hypervitaminosis A Hypervitaminosis A refers to the toxic effects of ingesting too much preformed vitamin A (retinyl esters, retinol, and retinal). Symptoms arise as a result of altered bone metabolism and altered metabolism of other fat-soluble vitamins. Hypervi ... caused by consumption of the liver of a polar bear.

The Veer is an option running play often associated with option offenses in American football, made famous at the collegiate level by Bill Yeoman's Houston Cougars. It is currently run primarily on the high school level, with some usage at the collegiate and the professional level where the Veer's blocking scheme has been modified as part of the zone blocking system. The Veer is an effective ball control offense that can help minimize mismatches in a game for a team. However, it can lead to turnovers with pitches and handoff option reads. Formations The Veer can be run out of any variety of formations, although it was primarily designed to be run out of the split-backed, aptly named veer formation. It has been used out of the I-formation (and its variants, including the Power-I and Maryland I) and the wishbone formation. Some variants of the triple option have now made the jump to the shotgun formation, which has become a popular option formation since Eric Crouch and ...

Willem Barentsz
Willem Barentsz (; – 20 June 1597), anglicized as William Barents or Barentz, was a Dutch navigator, cartographer, and Arctic explorer. Barentsz went on three expeditions to the far north in search for a Northeast passage. He reached as far as Novaya Zemlya and the Kara Sea in his first two voyages, but was turned back on both occasions by ice. During a third expedition, the crew discovered Spitsbergen and Bear Island, but subsequently became stranded on Novaya Zemlya for almost a year. Barentsz died on the return voyage in 1597. The Barents Sea, among many other places, is named after him. Life and career Willem Barentsz was born around 1550 in the village Formerum on the island Terschelling in the Seventeen Provinces, present-day Netherlands. ''Barentsz'' was not his surname but rather his patronymic name, short for ''Barentszoon'' " Barent's son". A cartographer by trade, Barentsz sailed to Spain and the Mediterranean to complete an atlas of the Mediterranean region, wh ...

Northeast Passage
The Northeast Passage (abbreviated as NEP) is the Arctic shipping routes, shipping route between the Atlantic Ocean, Atlantic and Pacific Ocean, Pacific Oceans, along the Arctic coasts of Norway and Russia. The western route through the islands of Canada is accordingly called the Northwest Passage (NWP). The NEP traverses (from west to east) the Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, and Chukchi Sea, and it includes the Northern Sea Route (NSR). The Northern Sea Route is a portion of the NEP. It is defined in Russian law and does not include the Barents sea and therefore does not reach the Atlantic Ocean. However, since the NSR has a significant overlap over the majority of the NEP, the NSR term is often used to refer to the entirety of the Northeast Passage. This practice injects confusion in understanding the specifics of both navigational procedures and jurisdiction. The Northeast Passage is one of several Arctic maritime routes, the others being the Northwest P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Novaya Zemlya Effect
The Novaya Zemlya effect is a polar mirage caused by high refraction of sunlight between atmospheric thermal layers. The effect gives the impression that the sun is rising earlier than it actually should, and depending on the meteorological situation, the effect will present the Sun as a line or a square — sometimes referred to as the rectangular sun — made up of flattened hourglass shapes. The mirage requires rays of sunlight to travel through an inversion layer for hundreds of kilometres, and depends on the inversion layer's temperature gradient. The sunlight must bend to the Earth's curvature at least to allow an elevation rise of 5° for sight of the solar disk. The first person to record the phenomenon was Gerrit de Veer, a member of Willem Barentsz's ill-fated third expedition into the north polar region in 1596–1597. Trapped by the ice, the party was forced to stay for the winter in a makeshift lodge on the archipelago of Novaya Zemlya and endure the polar night. ...

Hypervitaminosis A
Hypervitaminosis A refers to the toxic effects of ingesting too much preformed vitamin A (retinyl esters, retinol, and retinal). Symptoms arise as a result of altered bone metabolism and altered metabolism of other fat-soluble vitamins. Hypervitaminosis A is believed to have occurred in early humans, and the problem has persisted throughout human history. Toxicity results from ingesting too much preformed vitamin A from foods (such as fish liver or animal liver), supplements, or prescription medications and can be prevented by ingesting no more than the recommended daily amount. Diagnosis can be difficult, as serum retinol is not sensitive to toxic levels of vitamin A, but there are effective tests available. Hypervitaminosis A is usually treated by stopping intake of the offending food(s), supplement(s), or medication. Most people make a full recovery. High intake of provitamin carotenoids (such as beta-carotene) from vegetables and fruits does not cause hypervitaminosis A. ...

16th-century Dutch Explorers
The 16th century begins with the Julian year 1501 ( MDI) and ends with either the Julian or the Gregorian year 1600 ( MDC) (depending on the reckoning used; the Gregorian calendar introduced a lapse of 10 days in October 1582). The 16th century is regarded by historians as the century which saw the rise of Western civilization and the Islamic gunpowder empires. The Renaissance in Italy and Europe saw the emergence of important artists, authors and scientists, and led to the foundation of important subjects which include accounting and political science. Copernicus proposed the heliocentric universe, which was met with strong resistance, and Tycho Brahe refuted the theory of celestial spheres through observational measurement of the 1572 appearance of a Milky Way supernova. These events directly challenged the long-held notion of an immutable universe supported by Ptolemy and Aristotle, and led to major revolutions in astronomy and science. Galileo Galilei became a champi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Explorers Of Svalbard
Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most of ''Homo sapiens'' history, saw humans moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas. For the most part, these cultures were ignorant of each other's existence. The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. Early writings about exploration date back to the 4th millennium B.C. in ancient Egypt. One of the earliest and most impactful thinkers of ...
