those that have the greatest representation in terms of number of documents, are related to physics and chemistry. However, biochemistry and cell biology, medicine (pediatrics and pulmonary physiology), and, to a lesser extent, veterinary medicine and food science and technology are also noteworthy in the field of surfactants, which presents a markedly multidisciplinary profile.

C two markets of different sizes but similar costs and fare structure. All other things being equal, is an airline’s expected revenue larger in the market with larger demand? If not, under what circumstances is it possible to compare expected revenues without carrying out a detailed analysis? In this article, we provide answers to these questions by studying the relationship between the optimal...

The main aim of the present study was to investigate the extent to which East Franconian speakers neutralize the voicing opposition in intervocalic stops when they produce a variety of Standard German. A second aim was to test whether young and old speakers differ in their extent of neutralization and tend to a more standard-like pronunciation. We analyzed contrast maintenance by means of the v...

amygdaloidal, cavity- and fracture-filling zeolites in eocene volcanic rocks from the kuh-e-aradeh of southern kahrizak, in the northernmost part of central iran have been studied in some detail by optical, chemical analysis, sem, and xrd techniques. the zeolites identified, in order of their relative time of formation from early to late, are tetranatrolite, analcime, natrolite, mesolite, stilb...

The aim of the present study is to analyse unmyelinated nerve fibres of the human lesser splanchnic nerve in relation to the ageing process. With the help of an image-analyser, we examined 30 human lesser splanchnic nerves. The analysis was conducted with the use of a new staining method that makes it possible to discriminate various structures of the nervous tissue. Our report provides for the...

there are a lot of approximation techniques for structural optimization. among them, four outstanding approximation methods have been selected for trusses optimization. these approaches have been developed or modified by previous ones. based on these schemes, a lot of trusses have been optimized by author's program. this study shows that the abilities of the mentioned methods are not the s...
