George Philip Wells
George Philip Wells FRS (17 July 1901 – 27 September 1985) was a British zoologist and author. A son of the author H. G. Wells, he co-authored, with his father and Julian Huxley, ''The Science of Life''. A pupil at Oundle School, he was in the first class to learn Russian as a modern language in a British school. He accompanied his father to Soviet Russia in 1920, acting as his Russian translator and exchanging ideas with Russian zoology students. He won an entrance Exhibition to Trinity College, Cambridge, where he became Senior Scholar in his first year of residence.Lancelot Hogben, 1998. ''Scientific Humanist'', edited by Adrian Hogben and Anne Hogben Wells, a comparative physiologist, worked on invertebrates of several phyla. He determined their tolerance for changes in the salinity and the ionic balance of the surrounding water, and analysed the water relations of land gastropods. For the latter part of his career he was a member of staff in the Zoology Department of U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ionic Strength
The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts. One of the main characteristics of a solution with dissolved ions is the ionic strength. Ionic strength can be molar (mol/L solution) or molal (mol/kg solvent) and to avoid confusion the units should be stated explicitly. The concept of ionic strength was first introduced by Lewis and Randall in 1921 while describing the activity coefficients of strong electrolytes. Quantifying ionic strength The molar ionic strength, ''I'', of a solution is a function of the concentration of ''all'' ions present in that solution. :I = \begin\frac\end\sum_^ c_i z_i^ where one half is because we are including both cations and anions, ''c''i is the molar concentration of ion i (M, mol/L), ...

Academics Of University College London
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. 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 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, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Raymond Postgate
Raymond William Postgate (6 November 1896 – 29 March 1971) was an English socialist, writer, journalist and editor, social historian, mystery fiction, mystery novelist, and gourmet who founded the ''Good Food Guide''. He was a member of the Postgate family. Biography Early life Raymond Postgate was born in Cambridge, the eldest son of John Percival Postgate and Edith Allen, Postgate was educated at St John's College, Oxford, where, despite being sent down for a period because of his pacifism, he gained a First in Honour Moderations in 1917. Postgate sought exemption from World War I military service as a conscientious objector on socialist grounds, but was allowed only non-combatant service in the army, which he refused to accept. Arrested by the civil police, he was brought before Oxford Magistrates' Court, which handed him over to the Army. Transferred to Cowley Barracks, Oxford,Brock and Young, pp.209. for forcible enlistment in the Non-Combatant Corps, he was withi ...

The Outline Of History
''The Outline of History'', subtitled either "The Whole Story of Man" or "Being a Plain History of Life and Mankind", is a work by H. G. Wells chronicling the history of the world from the origin of the Earth to the First World War. It appeared in an illustrated version of 24 fortnightly installments beginning on 22 November 1919 and was published as a single volume in 1920. It sold more than two million copies, was translated into many languages, and had a considerable impact on the teaching of history in institutions of higher education. Wells modeled the ''Outline'' on the ''Encyclopédie'' of Denis Diderot. Revised editions Many revised versions were published during Wells's lifetime, and the author kept notes on factual corrections which he received from around the world. The last revision which was published during his lifetime was published in 1937. In 1949, an expanded version was produced by Raymond Postgate, who extended the narrative so it could include the Second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polychaetes
Polychaeta () is a paraphyletic class of generally marine annelid worms, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm (''Arenicola marina'') and the sandworm or clam worm ''Alitta''. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extremely high temperatures near hydrothermal vents. Polychaetes occur throughout the Earth's oceans at all depths, from forms that live as plankton near the surface, to a 2- to 3-cm specimen (still unclassified) observed by the robot ocean probe ''Nereus'' at the bottom of the Challenger Deep, the deepest known spot in the Earth's oceans. Only 168 species (less than 2% of all polychaetes) are known from fresh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oesophagus
The esophagus (American English) or oesophagus (British English; both ), non-technically known also as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''oesophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, “I carry”) + ἔφαγον (éphagon, “I ate”). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between layers of fibrous tissue, and an outer layer of connective tissue. The mucosa is a stratified squamous epithel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lugworm
The lugworm or sandworm (''Arenicola marina'') is a large marine worm of the phylum Annelida. Its coiled castings are a familiar sight on a beach at low tide but the animal itself is rarely seen except by those who, from curiosity or to use as fishing bait, dig the worm out of the sand. In the UK, the lugworm species ''Arenicola marina'' is commonly known as the blow lugworm, and rarely exceeds . There is a second species of UK lugworm ''Arenicola defodiens'' commonly called the black lugworm. As well as growing larger than blow lugworm (in line with descriptions for Europe and North America lugworm below) they are generally much darker, often totally black. They can be distinguished by the different wormcasts they produce - ''Arenicola defodiens'' makes a spiral cast, while that of ''Arenicola marina'' is jumbled. When fully grown, the lugworm of the coasts of Europe is up to long and in diameter. Other species on the North American coast range from . The body is like that of ...
