Schematic diagram: the “find-me” signal. Extracellular ATP secreted by apoptotic cells triggers P2Y2R signalling, thereby providing a “find-me” signal for phagocytes to promote phagocytic clearance of apoptotic cells. ATP adenosine-5′-triphosphate, P2Y2R P2Y purinoceptor 2. Sources: Refs....
The UV–Vis DRS spectrum (a) and band gap energy diagram (b) of Cu2O nanoparticle Full size image 3.3 Removing methylene blue with nano Cu2O photocatalyst The photocatalytic ability of Cu2O nanoparticle to oxidize dye (methylene blue) was evaluated under simulated sunlight conditions. Experimental ...
Yet, at the same time, few other parts of science are held to be so recondite. Mention of the Second Law raises visions of lumbering steam engines, intricate mathematics, and infinitely incomprehensible entropy. Not many would pass C.P. Snow’s test of general literacy, in which not ...
Without any diagram or symbolic aid he described the geometrical conditions on which the solution depended, and they seemed to stand out visibly in space. There were no longer consequences to be deduced, but real and evident facts which only required to be seen. … So whole and complete was...
Mexico’s vibrant autoparts sector Class exercise: Use the description of financial flows above to draw an annotated diagram or a map to show the financial flows associated with the manufacturing of vehicles in Mexico. If you can think of additional flows that might be important, add those as...
Even so elementary an operation as that of abstracting from the particular configuration of the triangles or other figures, and the relative situation of the particular lines or points, in the diagram which aids the apprehension of a common geometrical demonstration, is a very useful, and far ...
The X-ray diagram of structure B (see photograph) shows in striking manner the features characteristic of helical structures, first worked out in this laboratory by Stokes (unpublished) and by Crick, Cochran and Vand2. Stokes and Wilkins were the first to propose such structures for nucleic ...
Our fossil pachyderms, for instance, would be almost unintelligible but for the species which still inhabit some parts of Asia and Africa; the secondary marsupials are illustrated by their existing representatives in Australia and South America; and in the same manner, if we wish clearly to ...
Nothing afflicted Marcellus so much as the death of Archimedes, who was then, as fate would have it, intent upon working out some problem by a diagram, and having fixed his mind alike and his eyes upon the subject of his speculation, he never noticed the incursion of the Romans, nor ...
