この英語長文において、印刷技術の発達に必要な技術はどのようなものであるか50~200字で答えてください

木版画 鋳造 第3問 以下の文は、 S. Strandh の “Machines, an illustrated history" からの抜粋で ある。 次の文を読んで、設問に解答せよ。 (ア) The tools of precision mechanics were, without doubt, the technical pre conditions for making wood cuts and for the development of printing. The oldest dated wood engraving is from 1418. It shows fine lines throughout 細部 and a richness of detal, which imply that the tools used, the knives, burins, and so on, must have been eminently suitable At this time, it was only the precision mechanics of clock making which could achieve the technique required for such tools. 精密機械技術 (イ) A (woodcut was produced by transferring a drawing, reversed from left to right, onto a carefully surface-ground "block" of wood, after which the surface wood on either side of each line in the drawing was cut away with a burin of forged steel. The remaining wood on all 'surfaces which were to be white in the drawing were then cut away with gravers and gouges, so that the lines of the drawing became raised. They were then inked and pressed against paper. これは 理由では ないから、 (~のときに、何 が原因か は不明) The woodcut method spread rapidly in the late Middle Ages when pictures were rarity. At first, skilful craftsmen made the woodcuts, but before long, eminent artists were themselves cutting their own drawings in wood. One of the first was the German Albrecht Duerer (1479-1528) who, in 1498, published the famous pictorial series of the Revelation of St. John. Graphics had become an independent art form-based on the progress of precision 酒の mechanics! 可動式の The 1440s saw the first book printed with movable die-cast type. (The letter press printing method used by Johann Gutenberg (1399?-1468) was basically the same as the one used for printing woodcuts, but Gutenberg used cast, movable type instead of cut blocks. The production of dies for the type was made possible by the tools of precision mechanics, too. It does not detract from Gutenberg's contribution that printing with movable type has been practised in the Far East, or more specifically Korea, two thousand years prior to this. Several of the techniques described here, which developed so quickly during the technical revolution of the Renaissance, had had predecessors in other parts of the world.

至急お願いいたします🚨 生物の質問です。 ミトコンドリアの経路についての説明だと思うのですが、電子オーバーフローモデルと電子分布モデルの違いを教えていただきたいです。 また、どういう仕組みなのか、何故このように電子が流れるのかも教えていただきたいです。 UQ poolはユ... 続きを読む

(A) Electron overflow model (considered out-of-date) Alt UQ pool Alternative oxidase inactive. Alt No alternative pathway activity Cytochrome pathway unsaturated Cyt (B) Electron distribution model (reflects current thinking) UQ pool Cyt Alternative pathway active Cytochrome pathway saturated Alt Alternative oxidase active Alt UQ pool Cyt Cyt Figure 14.33 Two models for regulation of electron flow through the alternative oxidase. (A) In the electron overflow model, no appreciable electron transfer through the alternative pathway takes place until electron flow through the cytochrome pathway is at or near satu- ration. This could result from the effects of respirato- ry control, if the rate of mitochondrial ATP produc- tion exceeds its rate of utilization in the cytosol, or from some externally imposed stress, such as low temperature. Under such circumstances, the UQ pool becomes sufficiently reduced to allow electrons to flow through the alternative oxidase, the latter re- quiring that the UQ pool be 40% to 60% reduced to attain significant activity. (B) In the electron distribu- tion model, the alternative and cytochrome path- ways both show significant activity at low levels of UQ pool reduction, and electrons are distributed be- tween the two pathways on the basis of the relative activities of each pathway. The activity of the alter- native oxidase under these circumstances is thought to be regulated by the action of a-keto acids and by reduction/oxidation of the intermolecular disulfide bond, as well as by additional regulatory mecha- nisms not yet characterized.

humans. "We were able to identify one of the many molecular features that likely shape behavior," she adds. ** hol boquete es Though the origins of the dog/human partnership remain unknown, it's becoming increasingly clear that each species has changed (during our long years header The physical differences between a basset hound and wolf are obvious, but dogs have also changed in ways that are more than skin (or fur) deep. One recent study shows how by bonding with us and learning to work ogether with humans, dogs may have actually become worse at working together Their pack lifestyle and mentality appear to be reduced and are far as a species. less prevalent even in wild dogs than in wolves. But, Yale's Laurie Santos says, dogs may have compensated in other interesting ways. They've learned to use humans to solve problems. "Several researchers have presented dogs and wolves with an impossible problem (e.g., a puzzle box that can't be opened or a pulling tool that stops working) and have asked how these different species react," Santos explains. Researchers have found that wolves try lots of different trial and error tactics to solve the problem - they get at it physically. But at the first sign of trouble, dogs do something different. They look back to their human companion for help. This work hints that dogs may have lost some of their physical problem-solving abilities in favor of more social strategies, ones that rely on the unique sort of cooperation
