Jacques-Arsène D'Arsonval
Jacques-Arsène d'Arsonval (8 June 1851 – 31 December 1940) was a French physician, physicist and inventor of the moving-coil d'Arsonval galvanometer and the thermocouple ammeter. D'Arsonval was an important contributor to the emerging field of electrophysiology, the study of the effects of electricity on biological organisms, in the nineteenth century. Life D'Arsonval was born in the Château de la Borie, in La Porcherie, Haute Vienne, France. He studied medicine in Limoges and Paris and obtained his medical degree in 1877. From 1873 to 1878 he was assistant to Claude Bernard, one of the founders of experimental physiology. After Bernard’s death he assisted Charles-Édouard Brown-Séquard (1817-1894), giving his lectures, and when Brown-Séquard died in 1894 replaced him as professor at College de France. Influenced by Bernard, d'Arsonval decided to devote his life to research. In 1892, he became director of the new laboratory of biophysics at the College de France and c ...

Electric Shock
An electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. The injury depends on the Current density, density of the current, tissue resistance and duration of contact. Very small currents may be imperceptible or only produce a light tingling sensation. However, a shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling. A strong electric shock can often cause painful Spasm, muscle spasms severe enough to Joint dislocation, dislocate joints or even to Bone fracture, break bones. The loss of muscle control is the reason that a person may be unable to release themselves from the electrical source; if this happens at a height as on a Overhead power line, power line they can be thrown off. Larger currents can result in tissue damage and may trigger ventricular fibrillation or cardiac arrest. If death res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Staff Of The Collège De France
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and Skills, skill, north of Ancient Athens, Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the Gymnasium (ancient Greece), gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive Grove (nature), grove, hence the expression "the groves of Academe". In these gardens, the philos ...

Arthur Constantin Krebs
Arthur Constantin Krebs (16 November 1850 – 22 March 1935) was a French officer and pioneer in automotive engineering. Life Collaborating with Charles Renard, Krebs piloted Timeline of aviation - 19th century, the first fully controlled free-flight made in the French Army airship ''La France (airship), La France'', which was designed in 1884. The flight covered in 23 minutes. The flight landed back at its starting point. On its seven flights the ''La France'' dirigible returned five times to its starting point. Krebs and Renard shared the 1886 Ponti prize of the French ''Académie des sciences'' for their contribution to aerostation. Krebs inspired Jules Verne. In Verne's 1886 novel Voyages Extraordinaires, ''Robur The Conqueror'', he writes of "the striking experiments of Captain Krebs and Captain Renard".

Ocean Thermal Energy Conversion
Ocean thermal energy conversion (OTEC) is a renewable energy technology that harnesses the thermocline, temperature difference between the photic zone, warm surface waters of the ocean and the deep sea, cold depths to run a heat engine to produce electricity. It is a unique form of sustainable energy, clean energy generation that has the potential to provide a consistent and sustainable sourcing, sustainable source of power. Although it has challenges to overcome, OTEC has the potential to provide a consistent and sustainable source of clean energy, particularly in tropics, tropical regions with access to deep ocean water. Description OTEC uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful Work (physics), work, usually in the form of electricity. OTEC can operate with a very high capacity factor and so can operate in base load mode. The denser cold water masses, formed by ocean surface water inter ...

Georges Claude
Georges Claude (24 September 187023 May 1960) was a French engineer and inventor. He is noted for his early work on the industrial liquefaction of air, for the invention and commercialization of neon lighting, and for a large experiment on generating energy by pumping cold seawater up from the depths. He has been considered by some to be "the Edison of France". The Claude process for manufacturing ammonia was named for him. Claude was an active collaborator with the German occupiers of France during the Second World War, for which he was imprisoned in 1945 and stripped of his honors. Early life and career Georges Claude was born on 24 September 1870 in Paris, France, during the city's siege by German forces. Georges Claude studied at the École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI). He then held several positions.
