313) Anton Schrötter von Kristelli

Anton Schrötter von Kristelli (26 November 1802 – 15 April 1875) was an Austrian chemist and mineralogist born in Olomouc, Moravia. His son Leopold Schrötter Ritter von Kristelli (1837–1908) was a noted laryngologist.

Academic background

Anton's father was an apothecary. He initially studied medicine in Vienna at the request of his father, but switched to the natural sciences under the influence of Friedrich Mohs (1773–1839). In 1827 he became an assistant to mathematician Andreas von Ettingshausen (1796–1878) and to physicist Andreas von Baumgartner (1793–1865) at the University of Vienna. Three years later he was appointed professor of physics and chemistry at the Joanneum Technical Institute in Graz, and from 1843 served as a professor of technical chemistry at the Polytechnic Institute in Vienna. In 1845 he succeeded Paul Traugott Meissner (1778–1864) as chair of chemistry. In 1868 he was appointed Master of the Austrian State Mint (Münze Österreich). Declining health made him retire in 1874.

Contributions

As a chemist he conducted research involving reactions of metals with ammonia at higher temperatures, and performed investigations of substances such as amber, idrialite, ozokerite, asphalt and dopplerite. He also investigated the reactive behavior of potassium in liquid nitrous oxide, of phosphorus and antimony in liquid chlorine, and of iron towards oxygen at very low temperatures. In 1845 he discovered a process for preparing red phosphorus, a development which led to the invention of the safety match.

He was a scientific consultant to the Novara Expedition (1857–59), as well as to the Austro-Hungarian North Pole Expedition. His name is associated with the Schrötterhorn of the Ortlergruppe in the Alps and "Cape Schrötter" on Franz Josef Land.

With Ettingshausen, Baumgartner and Wilhelm von Haidinger (1795–1871), he was a founding member of the Austrian Academy of Sciences, serving as its secretary from 1851 until his death. Since 1876, the Schröttergasse in the Favoriten district of Vienna has been named in his honor.

106) Plytypus

Platypus, (Ornithorhynchus anatinus), also called duckbill, a small amphibious Australian mammal noted for its odd combination of primitive features and special adaptations, especially the flat, almost comical bill that early observers thought was that of a duck sewn onto the body of a mammal. Adding to its distinctive appearance are conspicuous white patches of fur under the eyes. The fur on the rest of the body is dark to light brown above, with lighter fur on the underside.

The platypus is common in waterways of eastern Australia, where it generally feeds on bottom-dwelling invertebrates but also takes an occasional frog, fish, or insect at the water’s surface. This shy creature forages most actively from dusk to dawn, sheltering during the day in burrows dug into stream banks. It is exquisitely adapted for its aquatic lifestyle, having a flattened torpedo-like body, dense waterproof fur, and strong front limbs used for swimming as well as digging. Even the head is streamlined, each ear being housed in a groove together with a small eye. The senses of sight, smell, and hearing are essentially shut down while the platypus is submerged to feed, but it possesses a unique electromechanical system of electroreceptors and touch receptors that allow it to navigate perfectly underwater (see also electroreception). Similar electroreceptors are also present in echidnas, which, together with the platypus, make up the mammalian order Monotremata, a unique group with an exceptionally ancient history.

Natural History

Platypuses are generally solitary, spending their lives either feeding along the bottoms of rivers, streams, and lakes or resting in burrows dug into the banks. They are extremely energetic, feeding almost continuously while in the water, shoveling through streambed debris with their flat bills as they hunt for larval insects and freshwater crustaceans (a favourite food). The platypus uses its sophisticated electromechanical system to detect minute electrical signals given off by the muscles of its prey. After feeding, it retires to its burrow, the entrance of which is large enough to admit only the platypus and serves to squeeze excess moisture from the fur.

The platypus is found in terrain ranging from the high country of Tasmania and the Australian Alps to lowland areas close to the sea. Although it has on occasion been seen swimming in salt water, the platypus must feed in fresh water, where its electrical navigation system is operative. The platypus is present in all eastern Australian states in both eastward- and westward-flowing river systems, but it is absent from far northern Queensland and, unlike its relatives, the echidnas, does not appear to have colonized the island of New Guinea.

Generally most active around dawn and dusk (crepuscular), platypuses can also be active during the day depending on the season, cloud cover, stream productivity, and even individual preference. Platypuses are not known to hibernate. However, they have an unusually low body temperature for mammals (about 32 °C [90 °F]). Studies have shown that they can maintain a constant body temperature even after extended periods in water with temperatures as low as 4 °C (39 °F), a fact that puts to rest the belief that monotremes cannot regulate their body temperature.

Form And Function

Platypuses range in length from 38 to 60 cm (15 to 24 inches); males are generally larger than females. Aquatic adaptations include the flat streamlined body, dorsally placed eyes and nostrils, and dense waterproof fur that keeps the platypus well insulated. Long guard hairs protect the soft underfur, which remains dry even after hours in the water. The extensive webbing on the front feet extends well past the claws and is essential in propelling the animal through the water. The paddlelike tail acts as a stabilizer during swimming, while the back feet act as rudders and brakes.

Odd skeletal features of platypuses include an archaic robust shoulder girdle and a short, wide humerus providing extensive muscle attachment areas for the exceptionally strong front limbs. The outside of the bill is covered by soft, sensitive skin. Inside the bill, adult platypuses do not have true teeth but instead have developed flat pads of hardened gum tissue. Male platypuses have a spur on the inner side of each ankle that is connected to a venom gland located over the thighs. The spurs can be wielded in defense, and the venom is potent enough to kill small animals and cause intense pain in humans if the spur penetrates the skin.

Evolution, Paleontology, And Classification

Aquatically adapted platypus-like monotremes probably evolved from a more-generalized terrestrial monotreme. The first occurrence in the fossil record of a platypus-like monotreme is from about 110 million years ago, in the early Cretaceous Period, when Australia was still connected to South America by Antarctica. Until recently this Cretaceous monotreme (Steropodon galmani, known by a stunning opalized jaw) was placed within the platypus family, but, partly on the basis of molecular studies and partly on dental structure, it is now classified in its own family, Steropodontidae.

The living platypus family (Ornithorhynchidae) includes the extinct genera Monotrematum (which dates to the Paleocene Epoch some 61 million years ago) and Obdurodon (which may have first emerged near the boundary of the Oligocene and Miocene epochs some 23 million years ago) and the living Ornithorhychus. The discovery of M. sudamericanum in 62-million-year-old Patagonian sediments confirmed that platypuses were once distributed through the southern continents that were once linked geographically (Gondwana). Species of Monotrematum and Obdurodon retained functional teeth and were more robust than the living platypus, Obdurodon measuring up to 60 cm (24 inches) long.

Hi,

#6759. Name the campaign to encourage wealthy people to contribute a majority of their wealth to philanthropic causes. As of 2017, the pledge has 158 signatories, either individuals or couples; some of the 158 have since died. Most of the signatories of the pledge are billionaires, and their pledges total over $365 billion. It does not actually dictate that the money is spent in any certain way or towards any particular charity or cause, and there is no obligation to actually donate any money.
