Other possible reasons for the deviations at higher surface coverages have also been put forward. From our derivation of the Elovich equation it follows that the main reason may be the neglect of the desorption kinetics inherent in the form of the Elovich equation. Moreover, there is the role of the lateral interactions between the adsorbed molecules. [Pg.395]

The lateral crack length for large contact loads when P Po is seen to depend on load as P which is a useful approximation when considering the role of the lateral crack system in ceramic erosion and in making estimates of the effects of collisions on ceramic surfaces. Perhaps this is the field where this analysis will be most used in ceramic systems. [Pg.254]

It also was found experimentally, in accordance with theoretical predictions, that the jamming coverage of hard spheres adsorbed irreversibly (in the limit of negligible electrostatic interactions) approached 55%. This value strongly decreases for lower ionic strength, hilly in accordance with the effective hard-particle concept. This hnding conhrmed the decisive role of the lateral electrostatic interactions in irreversible adsorption of colloid particles. [Pg.366]

The present article forms part of a larger study which will also consider the role of the later quantum mechanics in chemistry. [Pg.45]

It turns out that the CSP approximation dominates the full wavefunction, and is therefore almost exact till t 80 fs. This timescale is already very useful The first Rs 20 fs are sufficient to determine the photoadsorption lineshape and, as turns out, the first 80 fs are sufficient to determine the Resonance Raman spectrum of the system. Simple CSP is almost exact for these properties. As Fig. 3 shows, for later times the accuracy of the CSP decays quickly for t 500 fs in this system, the contribution of the CSP approximation to the full Cl wavefunction is almost negligible. In addition, this wavefunction is dominated not by a few specific terms of the Cl expansion, but by a whole host of configurations. The decay of the CSP approximation was found to be due to hard collisions between the iodine atoms and the surrounding wall of argons. Already the first hard collision brings a major deterioration of the CSP approximation, but also the role of the second collision can be clearly identified. As was mentioned, for t < 80 fs, the CSP... [Pg.373]

Dehydroquinic acid and [l,6-14C]-D-shikimic acid methyl ester were not incorporated, indicating a very early branch from the shikimate pathway. The intermediacy of 4-amino-3,4-dideoxy-D-araf>ino-heptulosonic acid 7-phosphate (37) was proposed, consistent with later findings on the role of the variant aminoshikimate pathway [94]. [Pg.408]

Lesions of the lateral hypothalamic area (LHA) cause anorexia, whereas ablation of the paraventricular nucleus (PVN) cause a hyperphagic obesity syndrome. Consistent with these results, LHA neurons express the orexigenic neuropeptides MCH and orexin. PVN neurons produce several neuropeptides that are anorex-igenic when administered directly into the brain (CRH, TRH, oxytocin), in addition to their better known roles as endocrine regulators. LHA and PVN receive rich inputs from axons of NPY/AgRP and aMSH/CART-producing neurons in the arcuate nucleus. [Pg.211]

Various initiation strategies and surfactant/cosurfactant systems have been used. Early work involved in situ alkoxyamine formation with either oil soluble (BPO) or water soluble initiators (persulfate) and traditional surfactant and hydrophobic cosurfactants. Later work established that preformed polymer could perform the role of the cosurfactant and surfactant-free systems with persulfate initiation were also developed, l90 222,2i3 Oil soluble (PS capped with TEMPO,221 111,224 PBA capped with 89) and water soluble alkoxyamines (110, sodium salt""4) have also been used as initiators. Addition of ascorbic acid, which reduces the nitroxide which exits the particles to the corresponding hydroxylamine, gave enhanced rates and improved conversions in miniemulsion polymerization with TEMPO.225 Ascorbic acid is localized in the aqueous phase by solubility. [Pg.482]

The capacity to translate between the levels The role of the symbolic level in the production of explanations changed as the sequence of activities was followed, becoming suitably dominant in the later lessons. At the same time, mental switching between the macro and sub-micro levels became ever more fluent. Moreover, during the process, students progressively increase their capacity to decide which level would be more adequate in a given situation. [Pg.304]

Figure 34-7 summarizes the roles of the intermediates and enzymes of pyrimidine nucleotide biosynthesis. The catalyst for the initial reaction is cytosolic carbamoyl phosphate synthase II, a different enzyme from the mitochondrial carbamoyl phosphate synthase I of urea synthesis (Figure 29-9). Compartmentation thus provides two independent pools of carbamoyl phosphate. PRPP, an early participant in purine nucleotide synthesis (Figure 34-2), is a much later participant in pyrimidine biosynthesis. Figure 34-7 summarizes the roles of the intermediates and enzymes of pyrimidine nucleotide biosynthesis.

The role of the DEAD is to activate the triphenylphosphine toward nucleophilic attack by the alcohol. In the course of the reaction the N=N double bond is reduced. As is discussed later, this method is applicable for activation of alcohols to substitution by other nucleophiles in addition to halide ions. The activation of alcohols to nucleophilic attack by the triphenylphosphine-DEAD combination is called the Mitsunobu reaction.76... [Pg.221]

The presence of a transporter can be assessed by comparing basolateral-to-apical with apical-to-basolateral transport of substrates in polarized cell monolayers. If P-gp is present, then basolateral-to-apical transport is enhanced and apical-to baso-lateral transport is reduced. Transport experiments are in general performed with radioactively labeled compounds. Several studies have been performed with Caco-2 cell lines (e.g. Ref. [85]). Since Caco-2 cells express a number of different transporters, the effects measured are most probably specific for the ensemble of transporters rather than for P-gp alone. P-gp-specific transport has been assayed across confluent cell layers formed by polarized kidney epithelial cells transfected with the MDR1 gene [86], Figure 20.11 shows experimental data obtained with these cell lines. A rank order for transport called substrate quality was determined for a number of compounds [86]. The substrate quality is a qualitative estimate, but nevertheless allows an investigation of the role of the air/water (or lipid/water) partition coefficient, log Kaw, for transport as seen in Fig. 20.11(A). For most of the compounds, a linear correlation is observed between substrate quality and log Kaw- However, four compounds are not transported at all despite their distinct lipophilicity. A plot of the substrate quality as a function of the potential of a... [Pg.481]
