Reputation mechanism

The shear strain of the conformational volume of m-ball and its rotation is realized in accordance with the reputational mechanism presented in Ref [2], that is, via the segmental movement of the polymeric chain, that is why is also the characteristic time of the own, that is, without the action g, rotation of m-ball [IT],... [Pg.137]

Let s determine the notion gearing as the thermod5mamical state of a monomeric link of the chain, at which its segmental motion is frozen. This means, that under the relative motion of the intertwining between themselves polymeric chains the reputational mechanism of the transfer at the expense of the segmental motion takes place, but under condition that the part of the monomeric links of a chain is frozen. [Pg.167]

The motion of two kinds of polymer chains in the transient double network can be performed by the following different reputation mechanisms [8]. [Pg.165]

Reputation Mechanism of the Polymeric Chains and Dynamic Reorganization [8]... [Pg.165]

With the above multiple dynamic and reversible reorganization (disentanglement and disadsorption, reentanglement and readsorption) of E and A-constituent chains on two kinds of polymer chains, the reputation mechanism leads to the displacement of mass center of polymeric chains and flow of fluids, and demonstrates relaxation spectrum and mechanical behaviors of polymeric suspensions. The corresponding rate constants are expressed as [8] ... [Pg.166]

The active principle of the autumn crocus (Colchicum autumnale), colchicine (48), is one of the very few drugs that have remained in reputable medical use since ancient times. This drug was the only useful treatment available for the excruciating pain associated with crystallization of uric acid in the joints characteristic of gout until the advent of allopurinol. Although the precise mechanism by which colchicine gives this dramatic relief remains undefined, the antimitotic activity of this agent is... [Pg.152]

To take radio-activity alone. .. perhaps there is no discovery of modern times which has so disorganized the fertile but by no means plastic brain and imagination of the workers in physical science as this bomb which overthrew with a mighty force all current and reputable theories of the constitution of Matter and its inherent quality. It was the assumption that Matter existed alone in the dense ponderable condition, which we have been told by generations of scientists is its main characteristic, that caused them to fabricate the Mechanical Theory of Nature.

The 1947 Nobel Prize in chemistry was to be awarded to Robinson to honor his work in the synthesis of natural products, investigations that he pursued all through his career, and a field in which his wife both collaborated and worked independently.87 Yet, in his memoirs, Robert Robinson wrote that he considered the development of an electronic theory of reaction mechanisms "my most important contribution to knowledge."88 This suggests the seriousness with which he viewed scientific theories and his belief that scientific glory and reputation rest on theories, not discoveries. Let us turn now to these theories. [Pg.200]

It is a well-known fact that a pharmaceutical substance can be prepared by adopting different routes of synthesis based upon the dynamic ongoing research in the field of organic-reaction-mechanisms. Relentless efforts are exerted vigorously by reputed research laboratories across the world to look for shorter routes of synthesis bearing in mind the cost-effectiveness of the final product. For instance diclofenac sodium (an NSAID) can be manufactured by two methods, one using a bromo compound as a starting material while the other is based on a non-bromo compound. Nevertheless, the latter product is more in demand because it is completely devoid of bromine residues in the final product. [Pg.5]

There are several remaining herbs that are reputed to have sedative effects skullcap, geranium, hops, and catnip. However, the neuropharmacological mechanisms have not been well characterized, and behavioral data in animals and humans are lacking. The existing knowledge on these plants is presented here. [Pg.243]

Ticks have a bad reputation for good reasons. Not only are they carriers of a number of diseases, the saliva of some can cause paralysis. North American natives were aware of tick paralysis, but the condition was officially noted as a disease of both animals and humans in 1912. The bites of at least 60 species of ticks can cause paralysis, which often does not appear until several days after the bite. The first indication is redness and swelling around the site of the bite. This is followed by neuromuscular weakness and difficulty in walking. If the tick is not removed, speech and breathing are affected, with eventual respiratory paralysis and death. Fortunately, removal of the tick results in a quick recovery of function. The exact mechanism of paralysis is not known but it appears to come from a substance that affects the neuromuscular junction. While not related to the venom of the tick saliva, the tick can also transmit diseases such as Lyme disease, Rocky Mountain spotted fever, Q fever, typhus, and others. Table 13.1 lists some venomous arachnids. [Pg.160]

Ilya Prigogine, the founding editor of Advances in Chemical Physics, died May 25, 2003. He was born in Moscow, fled Russia with his family in 1921, and, after brief periods in Lithuania and Germany, settled in Belgium, which was his home for 80 years. His many profound contributions to the theory of irreversible processes included extensions of both macroscopic thermodynamic analysis and statistical mechanical analysis of time-dependent processes and the approach to equilibrium. While sometimes controversial, these contributions were uniformly of outstanding intellectual merit and always addressed to the most fundamental issues they earned him international repute and the Nobel Prize in Chemistry in 1977. Arguably equally important was his creation of a school of theoretical chemical physics centered at the University of Brussels, as well as the mentoring of numerous creative and productive scientists. [Pg.392]
