Henri George Doll
Henri George Doll (13 August 1902 in Paris – 25 July 1991 in Montfort-l'Amaury, France) was a French-American scientist. Biography Doll was a leading figure in the development of oil well logging and a key technical leader of the Schlumberger oilfield services company. A graduate of the École Polytechnique and École des Mines, he married Anne Schlumberger, daughter of one of the Schlumberger brothers (Conrad), and joined their company. His contributions include the induction logging technique, and during World War II he led the development of the jeep-borne mine detector. He received a Certificate of Appreciation from the United States government, and was made an officer of the Légion d'honneur. Upon his retirement in 1967, the Schlumberger Well Surveying Corporation's research laboratory in Ridgefield, Connecticut was renamed the Schlumberger-Doll Research Center in his honor. The Schlumberger-Doll Research Center was relocated to Cambridge, Massachusetts in 200Sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montfort-l'Amaury
Montfort-l'Amaury () is a commune in the Yvelines department in the Île-de-France region, north central France. It is located north of Rambouillet. The name comes from Amaury I de Montfort, the first ''seigneur'' (lord) of Montfort. Geography Montfort-l'Amaury lies north of the Rambouillet Forest. It is located at the foot of low hills, at about 130 m above sea level. History King Robert II built a castle in 996 in the hills of Montfort. Montfort-l'Amaury was the stronghold of the Montfort family from the start of the 11th century. Amaury I built the ramparts. The Comté de Montfort was related to the Duchy of Brittany following the marriage of Yolande de Dreux-Montfort with Arthur of Brittany in 1294. It returned to the crown of France when Brittany became a part of France under Francis I. The castle was destroyed by the English during the Hundred Years' War.

Well Logging
Well logging, also known as borehole logging is the practice of making a detailed record (a ''well log'') of the geologic formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface (''geological'' logs) or on physical measurements made by instruments lowered into the hole (''geophysical'' logs). Some types of geophysical well logs can be done during any phase of a well's history: drilling, completing, producing, or abandoning. Well logging is performed in boreholes drilled for the oil and gas, groundwater, mineral and geothermal exploration, as well as part of environmental and geotechnical studies. Wireline logging The oil and gas industry uses wireline logging to obtain a continuous record of a formation's rock properties. Wireline logging can be defined as being "The acquisition and analysis of geophysical data performed as a function of well bore depth, together with the provision of related services." N ...

Groupe Des écoles Des Mines
The Groupe des écoles des mines (GEM) is a group of 8 Institut Mines-Telecom (IMT) engineering schools that are ''Grandes Écoles'', a French institution of higher education that is separate from, but parallel and connected to the main framework of the French public university system. Similar to the Ivy League in the United States, Oxbridge in the UK, and C9 League in China, ''Grandes Écoles'' are elite academic institutions that admit students through an extremely competitive process. Alums go on to occupy elite positions within government, administration, and corporate firms in France.

Mine Detector
Demining or mine clearance is the process of removing land mines from an area. In military operations, the object is to rapidly clear a path through a minefield, and this is often done with devices such as mine plows and blast waves. By contrast, the goal of ''humanitarian demining'' is to remove all of the landmines to a given depth and make the land safe for human use. Specially trained dogs are also used to narrow down the search and verify that an area is cleared. Mechanical devices such as flails and excavators are sometimes used to clear mines. A great variety of methods for detecting landmines have been studied. These include electromagnetic methods, one of which (ground penetrating radar) has been employed in tandem with metal detectors. Acoustic methods can sense the cavity created by mine casings. Sensors have been developed to detect vapor leaking from landmines. Animals such as rats and mongooses can safely move over a minefield and detect mines, and animals can als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Légion D'honneur
The National Order of the Legion of Honour (french: Ordre national de la Légion d'honneur), formerly the Royal Order of the Legion of Honour ('), is the highest French order of merit, both military and civil.

History Consulate During the French Revolution, all of the French orders of chivalry were abolished and replaced with Weapons of Honour.

Léonide Massine
Leonid Fyodorovich Myasin (russian: Леони́д Фёдорович Мя́син), better known in the West by the French transliteration as Léonide Massine (15 March 1979), was a Russian choreographer and ballet dancer. Massine created the world's first symphonic ballet, ''Les Présages'', and many others in the same vein. Besides his "symphonic ballets," Massine choreographed many other popular works during his long career, some of which were serious and dramatic, and others lighthearted and romantic. He created some of his most famous roles in his own comic works, among them the Can-Can Dancer in ''La Boutique fantasque'' (1919), the Hussar in ''Le Beau Danube'' (1924), and, perhaps best known of all, the Peruvian in '' Gaîté Parisienne'' (1938). Today his oeuvre is represented by his son Theodor Massine. Early life and education Massine was born into a musical family on 9 August 1895 in Moscow, Russia. His mother was a soprano in the Bolshoi Theater Chorus and his fath ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
