Results from the study

The distinction between in-plane A symmetry) and out-of-plane (A" symmetry) vibrations resulted from the study of the polarization of the diffusion lines and of the rotational fine structure of the vibration-rotation bands in the infrared spectrum of thiazole vapor. [Pg.54]

Durihg recent years a considerable amount of re-.search has been undertaken to understand what in the makeup of a polymer affects the processability. In the late 1980s, the Rubber Manufacturers Association in the United States undertook a research project with the Department of Polymer Engineering at the University of Akron to evaluate the laboratory equipment available using specially made butadiene-acrylonitrile polymers with different acrylonitrile levels, molecular weights, and molecular weight distributions. The results from the study confirmed that, from the processing variables viewpoint, the major factors are frequency (shear rate), temperature (temperature), and deformation (strain). [Pg.452]

One significant result from the studies of stretched premixed flames is that the flame temperature and the consequent burning intensity are critically affected by the combined effects of nonequidiffusion and aerodynamic stretch of the mixture (e.g.. Refs. [1-7]). These influences can be collectively quantified by a lumped parameter S (Le i-l)x, where Le is the mixture Lewis number and K the stretch rate experienced by the flame. Specifically, the flame temperature is increased if S > 0, and decreased otherwise. Since Le can be greater or smaller than unity, while K can be positive or negative, the flame response can reverse its trend when either Le or v crosses its respective critical value. For instance, in the case of the positively stretched, counterflow flame, with k>0, the burning intensity is increased over the corresponding unstretched, planar, one-dimensional flame for Le < 1 mixtures, but is decreased for Le > 1 mixtures. [Pg.118]

Thus, inflammatory factors play a role at all stages of atherosclerosis in its initiation, progression, and final clinical manifestations. This new understanding of the pathophysiology of atherosclerosis has partly resulted from the study of chemokines and their receptors (4). [Pg.200]

Forward step-wise MLR [24] was used to analyze the data obtained from the solubility investigations that follow. To compute Q2, we used MODDE software [25]. The results from the study reported in [1] are summarized in Eq. (2) ... [Pg.235]

New formulas, new stoichiometries, new structures, new reactants, new reducing agents, new oxidizing agents, and new areas of chemical research will result from the studies of chemical reactions in low-temperature matrices. [Pg.320]

In the study, five FRC samples, about 3 to 5 mm in thickness, were examined. The results from the study show that FRC materials have high resistance to ignition, high heat of gasification and high resistance to self-sustained fire propagation. These results suggest that a composite combat vehicle, by virtue of its construction, does not present an unusual fire hazard. [Pg.542]

The discovery of in vitro anti-HIV activity of macrocyclic polyamines by the Kimura and De Clercq groups led to development of a new type of effective anti-HIV agents. The results from the studies of the pharmacokinetics and their in vivo efficacy in a SCID-hu Thy/Liv mice are further encouraging indicators of their potential usefulness as new AIDS curing drugs. [Pg.162]

The results from the study into identical accidents show that precursors often do exist prior to accidents. The existence of precursors prior to accidents creates the opportunity to derive indicators for accidents. To actually obtain a better understanding of how and why accidents can occur in spite of the presence of precursors prior to accidents, in the next Section 17 recent accidents from the Dutch chemical process industry will be analysed using the 7-stage protocol. [Pg.110]

Equations (83) and (87)-(89) have been used to estimate values for the LTU in the studies conducted by Coughlin and Canevari (1%9) and by Werner (1980). These results are summarized in Table II along with the results from the study of Collins et ah (1983). The results in this table provide support for the idea that the LTU can be used as a measure of the effectiveness of the extraction unit. [Pg.101]

How modeling has been useful in the crystal structure analysis of polysaccharides—and how it could lead to a better understanding of other condensed j)hase states—can be illustrated with structural worK done on cellulose. It is one of the world s most important and widely used raw materials whose structure, properties, derivatives, and transformations remain under continuous study. Some of the results, problems, and indications of future directions resulting from the study of its crystalline structure—and the attendant roles for molecular modeling—are briefly described in the following. [Pg.346]

Best and coauthors utilized IR spec-troelectrochemistry to study the electrochemical reduction of 1902 " " in aqueous solutions with KNO3 as supporting electrolyte [60]. The pH of the solutions was set with appropriate quantities of HNO3 and KOH. The optimal pH range for the study was 2.8-3.4, since within this range speciation of U(VI) is limited to U02 + and (U02)2(0H)2 " ", disproportionation of the electrogenerated U(V) species is minimized, and the U—O stretches for U(VI) are observable in the IR spectrum. The results from the study indicate that initial reduction of at a platinum elec-... [Pg.1059]

The results from the study of the picosecond time resolved Stake s shift of the laser dye coumarin 480 in AOT/heptane-RMs [315] indicated that the water molecules in the water pool undergo slow relaxation on the nanosecond time scale. [Pg.172]

To reveal the cognition-enhancing potential of the S-HTj antagonists, studies in age-related memory impairment have been carried out with psy-chiatrically healthy subjects impaired with scopolamine and patients with dementia. In a randomized double-blind, double-dummy, four-way crossover study in a small number of subjects, each psychiatrically healthy male subject received placebo, scopolamine [0.4 mg im], scopolamine plus alosetron [10 J,g iv], or alosetron [250 Jg] [Preston 1994 Preston et al. 1991). Assessments of verbal and spatial memory, sedation, and sustained attention were performed before and after treatment. The main results from the study were that scopolamine induced robust deficits on all primary variables measured, the reduction in verbal and spatial memories being attenuated by 10- Jg and 250- Jg doses of alosetron, respectively. No effects on the sedation or on changes in attention were noted. [Pg.555]

The Swiss Agency of Environment and Landscape decided to re-evaluate mechanical metal separation techniques to reduce the landfill volume and to improve the BA quality for deposition by exploiting metal resources. A sampling campaign in all 28 incineration plants was initiated to verify BA quality and to establish a solid data base. A common sampling procedure, sample treatment, and analytical method were prescribed in order to obtain consistent information of chemical and structural composition and the leaching behaviour of current BA. This paper is focused on the chemical and mineralogi-cal results from the study. [Pg.412]

The results from the studies described above indicate that the MSLT provides a robust measure of sleepiness that is sensitive to sleep restriction in children and adolescents (112). Patterns of sleep latency from repeated naps during constant routine protocols or forced desynchrony protocols in older children and adolescents also illustrate the influences of both homeostatic and circadian processes on sleepiness/alertness and provide evidence for the hypothesis that... [Pg.166]

Lithium may be of some value in the treatment of difficult, impulsive and aggressive adolescents and children but the results from the studies in which lithium was used are few and the outcome uncertain. [Pg.420]
