Advent M. Kodaira's vanishing theorem, asserting that the inverse of an plentiful invert­ ible sheaf on a projective complicated manifold X has no cohomology less than the size of X and its generalization, as a result of Y. Akizuki and S. Nakano, were confirmed initially via tools from differential geometry ([39J and [1]). whether, because of J.P. Serre's GAGA-theorems [56J and base swap for box extensions the algebraic analogue used to be bought for projective manifolds over a box ok of attribute p = zero, for a very long time no algebraic facts used to be identified and no generalization to p > zero, aside from convinced reduce dimensional manifolds. Worse, counterexamples as a result of M. Raynaud [52J confirmed that during attribute p > zero a few extra assumptions have been wanted. This was once the cutting-edge till P. Deligne and 1. Illusie [12J proved the degeneration of the Hodge to de Rham spectral series for projective manifolds X outlined over a box ok of attribute p > zero and liftable to the second one Witt vectors W2(k). average degeneration arguments enable to infer the degeneration of the Hodge to de Rham spectral series in attribute 0, to boot, a re­ sult which back might basically be bought by means of analytic and differential geometric tools previously. As a corollary in their tools M. Raynaud (loc. cit.) gave a simple evidence of Kodaira vanishing in all features, only if X lifts to W2(k).

The Wellborn Science: Eugenics in Germany, France, Brazil, and Russia (Monographs on the History and Philosophy of Biology)

The 4 participants to this quantity study the eugenics routine in Germany, France, Brazil, and the Soviet Union, and describe how geneticists and physicians participated within the improvement of guidelines about the development of hereditary traits in people. They research the clinical elements of these courses and speak about the involvement of social, spiritual, and political forces that considerably altered the unique medical pursuits.

Science vs. Religion: What Scientists Really Think

That the longstanding antagonism among technology and faith is irreconcilable has been taken with no consideration. And within the wake of modern controversies over educating clever layout and the ethics of stem-cell learn, the divide turns out as unbridgeable as ever. In technology vs. faith, Elaine Howard Ecklund investigates this unexamined assumption within the first systematic examine of what scientists truly imagine and believe approximately faith.

The Man in the Monkeynut Coat: William Astbury and the Forgotten Road to the Double-Helix

Sir Isaac Newton as soon as declared that his momentous discoveries have been simply made due to having 'stood at the shoulders of giants'. an identical may also be acknowledged of the scientists James Watson and Francis Crick. Their discovery of the constitution of DNA used to be, definitely, one of many largest medical landmarks in heritage and, thank you principally to the luck of Watson's best-selling memoir 'The Double Helix', there may appear to be little new to claim approximately this tale.

Visual Cultures in Science and Technology: A Comparative History

This publication deals a vast, comparative survey of a booming box in the background of technology: the background, new release, use, and serve as of pictures in clinical perform. It explores each element of visuality in technology, arguing for the concept that of visible domain names. What makes a great medical photograph? What cultural luggage is key to it?
