Mikhail Lavrentyev

Mikhail Alekseevich Lavrentyev was a Soviet mathematician and hydrodynamicist. Lavrentiev was born in Kazan. Lavrentiev entered Kazan University, when his family moved to Moscow in 1921, he transferred to the Department of Physics and Mathematics of Moscow University, he graduated in 1922. He continued his studies in the university in 1923-26 as a graduate student of Nikolai Luzin. Although Luzin was alleged to plagiarize in science and indulge in anti-Sovietism by some of his students in 1936, Lavrentiev did not participate in the notorious political persecution of his teacher, known as the Luzin case or Luzin affair. In fact Luzin was a friend of his father. In 1927 Lavrentiev spent half a year in France, collaborating with French mathematicians, upon returned took up a position with Moscow University, he became a member of the staff of the Steklov Institute. His main contributions relate to partial differential equations. Mstislav Keldysh was one of his students. In 1939 Alexander A. Bogomolets, the president of the Ukrainian Academy of Sciences, asked Lavrentev become director of the Institute of Mathematics at Kiev One of Lavrentiev's scientific interests was the physics of explosive processes, in which he had become involved when doing defense work during World War II.

A better understanding of the physics of explosions made it possible to use controlled explosions in construction, the best-known example being the construction of the Medeu Mudflow Control Dam outside of Almaty in Kazakhstan. Mikhail Lavrentiev was one of the main organizers and the first Chairman of the Siberian Division of the Russian Academy of Sciences from its founding in 1957 to 1975; the foundation of the Siberia's "Academic Town" Akademgorodok remains his most known achievement. Six months after the decision to found the Siberian Division of the USSR Academy of Sciences Novosibirsk State University was established; the Decree of the Council of Ministers of the USSR was signed January 9, 1958. From 1959 to 1966 he was a professor at Novosibirsk State University. Lavrentyev was a founder of the Institute of Hydrodynamics of the Siberian Division of the Russian Academy of Sciences which since 1980 has been named after Lavrentiev. Lavrentiev was awarded the honorary title of Hero of the Socialist Labour, a Lenin Prize and USSR State Prize, a Lomonosov Gold Medal.

He was elected a member of several world-renowned academies, an honorable citizen of Novosibirsk. Mikhail A. Lavrentiev's son named Mikhail became a mathematician and was a member of the leadership of Akademgorodok.

Orientate is an American Thoroughbred racehorse who won the 2002 Breeder's Cup Sprint and was voted the U. S. Champion Sprint Horse of 2002. A descendant of the great Nearco through his son Royal Charger, Orientate was bred by Gainesway Thoroughbreds Ltd. and raced by Bob & Beverly Lewis. He was sired by American multiple stakes winner Mt. Livermore and out of the Cox's Ridge mare, Dream Team. Trained by U. S. Racing Hall of Fame inductee D. Wayne Lukas, Orientate retired from racing having won ten of his nineteen starts with earnings of US$1,716,950. Purchased by Gainesway in partnership with Arrowfield Stud of Australia, Orientate was sent to stand at stud at Gainesway Farm near Lexington, Kentucky. Among his successful racing offspring to date includes American Grade I winner Lady Joanne and the Australian Grade II winner, Marveen

Mount Hanang

Mount Hanang is a mountain in Tanzania. The peak has an elevation of 3,420 m above sea level. Hanang is located in Hanang District, it is the fourth-highest mountain in Tanzania, if you count the three peaks of Kilimanjaro as one mountain. The principal path to the summit starts in the town of Katesh; the climb can be done in one day, but it is common for climbers to spend one night in a tented camp on the mountain and reach the summit on the second day. Mount Hanang Nature Forest Reserve has an area of 58.66 km², protecting an enclave of evergreen montane forest on the mountain's higher slopes. Between 2000 and 2700 meters elevation, evergreen montane forest covers the mountain's wetter eastern southern slopes, while the drier western and northern slopes are home to dry montane evergreen forest with bushland and grassland on the ridges. Above 2700 meters, the forests transition to ericaceous heathland and high-altitude grasslands. List of Ultras of Africa Manyara Region

Taraxasterol is a triterpene derived from the mevalonate pathway and is found in dandelions. The precursor for the biosynthesis of taraxasterol is squalene. In the first step of this formation squalene is cyclized with molecular oxygen, FAD, NADPH via the enzyme squalene epoxidase a flavoprotein to yield -2,3-oxidosqualene. In the second step if the oxidosqualene is folded in the chair conformation in the enzyme a cascade of cyclizations will occur that results in the formation of the dammarenyl cation; the dammarenyl cation is subjected to an alkyl shift to create a six-membered ring and relieving ring strain to form the baccharenyl cation. This allows the baccharenyl double bond to attack the secondary positive charge and forms a pentacyclic ring system to yield the tertiary lupanyl cation. A Wagner-Meerwein 1,2-alykl shift will occur to form the hexacyclic ring system and the secondary oleanyl cation; this is followed by a Wagner-Meerwein 1,2-methyl shift to create the tertiary taraxasteryl cation.

This cation is the last intermediate in the taraxasterol pathway. An E2 reaction follows; the enzymes involved in this biosynthesis are oxidosesqualene: lupeopl cyclase and oxidosqualene: B-amyrin cyclase
