Joseph Bienaimé Caventou
Joseph Bienaimé Caventou (; 30 June 1795 – 5 May 1877) was a French pharmacist. He was a professor at the École de Pharmacie (School of Pharmacy) in Paris. He collaborated with Pierre-Joseph Pelletier in a Parisian laboratory located behind an apothecary. He was a pioneer in the use of mild solvents to isolate a number of active ingredients from plants, making a study of alkaloids from vegetables. Among their successes were the isolation of the following compounds: Quinine sulfate later proved to be an important remedy for the disease malaria. Quinine is the active anti-malarial ingredient in the bark of cinchona tree. Neither of the partners chose to patent their discovery of this compound, releasing it for everybody to use. In 1823 they discovered nitrogen in alkaloid compounds. Other compounds they discovered include colchicine and veratrine. The crater Caventou on the Moon The Moon is Earth's only natural satellite.

Saint-Omer
Saint-Omer (; ; Picard: ''Saint-Onmé'') is a commune and sub-prefecture of the Pas-de-Calais department in France. It is west-northwest of Lille on the railway to Calais, and is located in the Artois province. The town is named after Saint Audomar, who brought Christianity to the area. The canalised section of the river Aa begins at Saint-Omer, reaching the North Sea at Gravelines in northern France. Below its walls, the Aa connects with the Neufossé Canal, which ends at the river Lys. History Saint-Omer first appeared in the writings during the 7th century under the name of Sithiu (Sithieu or Sitdiu), around the Saint-Bertin abbey founded on the initiative of Audomar, (Odemaars or Omer). Omer, bishop of Thérouanne, in the 7th century established the Abbey of Saint Bertin, from which that of Notre-Dame was an offshoot. Rivalry and dissension, which lasted till the French Revolution, soon sprang up between the two monasteries, becoming especially virulent when ...

Cinchonine
Cinchonine is an alkaloid found in ''Cinchona officinalis''. It is used in asymmetric synthesis in organic chemistry. It is a stereoisomer and pseudo-enantiomer of cinchonidine. It is structurally similar to quinine, an antimalarial drug. It is a GLP-1 receptor agonist and therefore has potential as a possible treatment for obesity, type 2 diabetes, and non-alcoholic fatty liver disease.

People From Saint-Omer
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States).
