Ampelopsin

Ampelopsin known as dihydromyricetin, is a flavanonol, a type of flavonoid. It is found in the Ampelopsis species japonica and grossedentata. Hovenia dulcis has been used in traditional Japanese and Korean medicines to treat fever, parasitic infection, as a laxative, a treatment of liver diseases, as a hangover treatment. Methods have been developed to extract ampelopsin from it at large scales, laboratory research has been conducted with the compound to see if it might be useful as a drug in any of the conditions for which the parent plant has been traditionally used. In a trial of sixty patients with fatty liver disease dihydromyricetin improved glucose and lipid metabolism and exerted anti-inflammatory effects which were beneficial. Dihydromyricetin shows promise as an alcohol anti-intoxicant

Lookout Studio

Lookout Studio, known as The Lookout, is a stone building located on the South Rim of the Grand Canyon, within Grand Canyon National Park in Arizona. It is part of the Grand Canyon Village Historic District, is part of the Mary Jane Colter Buildings National Historic Landmark, it operates as a gift shop and observation station for visitors, with telescopes on its outdoor terrace. Lookout Studio was constructed by the Santa Fe Railway in 1914 and was established as a photography studio to compete with Kolb Studio, it is one of six buildings at the Grand Canyon that were designed by architect Mary Colter, along with Bright Angel Lodge, Hermit's Rest, Hopi House, Phantom Ranch, Desert View Watchtower. Lookout Studio employs her signature rustic style of using jagged native rocks to imitate indigenous structures of the region and to blend in with the environment; the rubble stone building is at the edge of the canyon. The walls rise to an irregular parapet. Before a roof replacement the roof carried a pile of stones designed to look like they had fallen into ruin.

The lookout is on three levels, with a main level housing a shop and enclosed viewing area, a lower viewing platform and a small enclosed observation tower. The wood viga roof structure remains visible, although the structure has undergone other renovations; the lookout is unusually brightly lighted for a Colter building, since its interior receives a great deal of light through its banks of large windows. Lookout Studio is a component of the multi-site Mary Jane Colter Buildings National Historic Landmark, It was incorporated into the National Historic Landmark group on May 28, 1987. Hopi House and the Lookout Studio are major contributing structures in the Grand Canyon Village National Historic Landmark District. National Park Service historic photos of Lookout Studio M. E. J.

Louis Dangeard

Louis Marie Bernard Dangeard was a French geologist and oceanographer. He was son of the mycologist Pierre Augustin Dangeard, his brother was the botanist Pierre Dangeard. Louis Dangeard was one of the founders of modern oceanography. Louis Dangeard was born on April 1898 in Poitiers, he was the youngest of four siblings. His father had come from Caen in 1891 to take up a professorship at the Académie des Sciences, the scientific faculty of the University of Poitiers. In 1909 the family moved to Paris, where his father had been offered a post at the prestigious scientific faculty of the University of Paris. Louis Dangeard studied geology in Paris and, in 1919 moved to the scientific faculty of the University of Rennes working as an academic assistant. In 1923 he was offered a permanent position and, in 1928, he was promoted to assistant professor. From 1922 to 1927 he took part in seven oceanographic expeditions organized by Jean Charcot with the research vessel Pourquoi Pas?. These research trips covered the Bay of Biscay and in particular the English Channel.

Dangeard's main focus of research was the investigation of the seabed. In 1928 he received his doctorate with a thesis on the geology of the seabed of the English Channel. In 1930 Dangeard was appointed professor of geology at the scientific faculty of the University of Clermont-Ferrand, but switched in 1933 to the Chair of Geology at the Faculté des Sciences at the University of Caen, Lower Normandy, where he succeeded Alexandre Bigot, his scientific work concentrated on sedimentology and petrography. By January 1926, Louis Dangeard had married the 22-year-old Louise Marie Joseph Marcille; the couple had six children: Henri, Alain, Anne and Gilles Louise Marie. He retired from his professorial chair at the University of Caen in 1968, his wife died in 1980, Dangeard died in 1987 at the age of 88. Dangeard was a member of the French Geological Society. During his lifetime a valley system of the eastern English Channel was named the Fosse Dangeard in his honor. 1955 elected President of the French Geological Society Louis Dangeard: La Normandie.
