Mutual enhancement

The same effect of mutual enhancement of adsoi ption was observed in the spectra of amoi phous ice for ethylene and CHF coadsorbed at 77K. 

Since a herbal combination has obvious advantages in treatment, the relationships between the herbs used in traditional Chinese medicine (TCM) have been carefully studied and certain types of relationship are identified. They are called the seven relations between herbs, e.g. mutual accentuation, mutual enhancement, mutual counteraction, mutual suppression, mutual antagonism, mutual incompatibility and single effect. Some of these are very useful in treatment, but some are harmful and therefore must be avoided. 

Of the above seven types of relationship, those of mutual accentuation and mutual enhancement are commonly used in treatment mutual counteraction and mutual suppression can also be used, especially to reduce herbs side effects or toxicity. The single herb effect is only used in a limited number of disorders relations of mutual antagonism and mutual incompatibility should be avoided in treatment.

The key points from these experiments are that the more easily replaceable monophosphine ligands are required for the reduction of N2, which is favored by the presence of oxo-anions. Thus, as the reaction proceeds and electron density passes from metal to N2, the 7r-acceptor phosphines are replaced successively by 7r-donor oxo species. This change in ligand encourages further release of metal electron density onto the bound, partially reduced N2, which results in its protonation. This resulting effective increase in the oxidation state of the metal then causes further substitution of the softer phosphines by the harder oxo-anions. These mutually enhancing effects result ultimately in complete loss of all phosphine ligands and the production of NH3.

Correct answer = D. MAO inhibitors and aspirin can be taken concurrently. Hypertensive crisis may result from use (concurrently or within 2 weeks) of MAO inhibitors and indirect sympathomimetic amines, such as ephedrine. Concomitant use of MAO inhibitors and tricyclic antidepressants may result in mutual enhancement of effects with the possibility of hyperpyrexia, hypertension, seizures and death. Tyramine-containing foods, such as aged cheeses and beer, may precipitate a hypertensive crisis because of the accumulation and release of stored catecholamines from nerve endings. MAO inhibitors may lead to an exaggerated response to dopamine. 

Coadsorption of reactants and subsequent thermal decomposition of the surface complexes formed have been used to resolve the mechanisms in several studies (81-84). Mutual enhancement of the adsorbed amounts of the reactants is indicative of their interaction, and if the adsorption of separately admitted components is negligible, the stoichiometry of the adsorbed complex can be determined. Further evidence for the formation of an adsorbed complex, employed in a mechanistic study of methanol synthesis over ZnO (84), is obtained by thermal decomposition of the adsorbed complex if the reactants appear simultaneously at one temperature upon thermal desorption from a coadsorbed layer, but if each reactant adsorbed separately gives a thermal desorption peak at a different temperature, the existence, although not necessarily the structure or com-... 

It is important to realize that the Self-Avoiding MIDCO approach is not a fuzzy set version of a hard surface contact model. If various parts of a macromolecule are placed side by side, then the electronic density charge clouds mutually enhance each other due to their partial overlap, resulting in an actual shape change of these electron density clouds. The various MIDCOs G(K,a) experience significant swelling due to this overlap. The merger of the local parts of the MIDCO actually occurs at a point r that would fall on the outside of each individual MIDCO part without the presence of the other MIDCO part. 

Malmstadt and Chambers (M2) with their nuUpoint instrument and standard addition method obtained high accuracies they state that no interference was seen from an excess of sodium. The latter is difficult to understand since the degree of mutual ionization depression between alkali metals at a particular flame temperature can be predicted (F6), and has been experimentally demonstrated in absorption with flames of comparable or even lower temperature (B2, Wll). On the other hand, the use of the standard addition method may have minimized the sodium interference and, since the mutual enhancement effect in absorption seems to be smaller than in emission (B2), it may have been negligible in the measurements. 

Apart from these three prerequisites, leading to the general form of kinetic equations as represented in Appendix 3, no specific interactions among the constituents—such as mutual enhancement or suppression, recombinative exchange, or other regulative couplings—have been assumed. 

Most wastewater contain compounds that may mutually enhance, interfere, or act independently in the adsorption process. Factors affecting overall adsorption of multiple adsorbates include the relative molecular size and configuration, the relative adsorptive affinities, and the relative concentration of the solutes.

The possibility of preparing protein crystals in equilibrium with cryosolvents (64) mutually enhances the value of crystal analysis by X-ray diffraction at low temperatures and of the cryoenzymological approach. By this means it has become possible to compare reactive intermediate forms trapped in the crystalline state and in solution, respectively (63).
