Profile multiple

In terms of free-energy surfaces, multiple electron transitions correspond to multiple transitions between various free-energy surfaces of the initial and final states, and the system in fact moves along some effective potential profile. Multiple electron transitions allow one to speak about an average occupation of the... 

The first step in risk assessment is to gather health-related information associated with an exposure. Ideally, hazard identification starts before there is significant use of the agent. The structure of the compound is compared with that of compounds with known toxicity profiles. Cell-based studies are often performed to screen for toxicity. Finally, animal bioassays and human studies are performed to characterize and develop a toxicity profile. Multiple health-related endpoints are evaluated to determine if the compound is associated with adverse effects. Advantages of animal studies include experimental control and accurate knowledge of the dose.

Odorivector molecviles can contain an almost unlimited number of profiles. Of these are only a few explicit, but with increasing conformational freedom a rapidly increasing number of implicit ones are potentially possible. This raises the question about the number of complementary receptor sites necessary to deal unambiguously and efficiently with the transcription of structural into informational modalities. The concept of multiple profile - multiple receptor sites provides no indication how the actual number of receptor site types covild be deduced. However the minimum number required to encode the total olfactory spectrum perceived by man can be estimated by means of basic principles of information theory. For that a few simple assmptions have to be made ... 

Up to this point only speculations have been presented. They were based on the assiomption that the peripheral process in olfaction is mediated by specific receptor sites of a group of membrane bound adenyl cyclases and that the Multiple Profile - Multiple Receptor Site concept is viable. If these assumptions are correct the following extrapolations could be made ... 

In the preceding section, the choice of reactor type was made on the basis of which gave the most appropriate concentration profile as the reaction progressed in order to minimize volume for single reactions or maximize selectivity for multiple reactions for a given conversion. However, after making the decision to choose one type of reactor or another, there are still important concentration effects to be considered. 

Because the characteristic of tubular reactors approximates plug-flow, they are used if careful control of residence time is important, as in the case where there are multiple reactions in series. High surface area to volume ratios are possible, which is an advantage if high rates of heat transfer are required. It is sometimes possible to approach isothermal conditions or a predetermined temperature profile by careful design of the heat transfer arrangements. 

In this paper, discontinuities in cylindrical specimens were studied by ultrasonic reflection tomography. The aim was threefold. First, to localize discontinuities from circular C-scan images. Second, to reconstruct quantitative cross-sectional images from circular B-scan profiles (i.e., reflection tomograms). Finally, to obtain three-dimensional information (i.e., discontinuity location, dimension and type) by stacking these reflection tomograms in multiple planes, in the third dimension. 

The two most common temporal input profiles for dmg delivery are zero order (constant release), and half order, ie, release that decreases with the square root of time. These two profiles correspond to diffusion through a membrane and desorption from a matrix, respectively (1,2). In practice, membrane systems have a period of constant release, ie, steady-state permeation, preceded by a period of either an increasing (time lag) or decreasing (burst) flux. This initial period may affect the time of appearance of a dmg in plasma on the first dose, but may become insignificant upon multiple dosing.
