Echtzeitmessung reaktiver Prozessgase in der Mikroelektronik mittels FTIR Spektroskopie
Authors: Mohn J. , Gälli R. , Emmenegger L. 
Published: September 2006

AbstractBei der Herstellung von Mikroelektronikbausteinen werden zahlreiche sehr teure, reaktive und klimaschädigende Prozessgase eingesetzt. Deshalb haben die entsprechende Prozessoptimierung, sowie die Entwicklung und Kontrolle geeigneter Recycling‐ bzw. Abgasreinigungseinrichtungen, eine große wirtschaftliche und ökologische Bedeutung. Grundlage dafür ist die kontinuierliche Bestimmung der Prozessgaszusammensetzung mit hoher Präzision und zeitlicher Auflösung. Im Rahmen der vorliegenden Arbeit wurde eine dafür geeignete Messmethode, basierend auf der Fourier Transform Infrarot (FTIR) ‐Spektroskopie, entwickelt und validiert.

Nukleation und Phasenumwandlung in Scherströmungen
Authors: aus der Wiesche S. 
Published: September 2006

AbstractMit Hilfe von dreidimensionalen direkten Simulationen wird die Dynamik von einzelnen Blasen in einer linearen Scherströmung untersucht. Für einen großen Bereich von Viskositäts‐ und Dichteverhältnissen der beiden Phasen werden Korrelationen für die Deformation und den Blasenzerfall als Funktion der Kapillar‐Zahl abgeleitet. Weiterhin wird das Wachstum von Dampfblasen unter Berücksichtigung der Nichtgleichgewichtsthermodynamik in der Scherströmung qualitativ ausgewertet. Die numerischen Simulationen stützen ebenfalls die These, dass neben dem klassischen Blasenzerfallsmechanismus auch noch ein schleichendes Schrumpfen (tip‐streaming effect) im Falle genügend großer Scherströmungen im Rahmen der Kontinuumstheorie existieren kann.

Mapping the Fluorophilicity of a Hydrophobic Pocket: Synthesis and Biological Evaluation of Tricyclic Thrombin Inhibitors Directing Fluorinated Alkyl Groups into the P Pocket

Published: September 2006

AbstractIn the completion of our fluorine scan of tricyclic inhibitors to map the fluorophilicity/fluorophobicity of the thrombin active site, a series of 11 new ligands featuring alkyl, alkenyl, and fluoroalkyl groups was prepared to explore fluorine effects on binding into the hydrophobic proximal (P) pocket, lined by Tyr 60A and Trp 60D, His 57, and Leu 99. The synthesis of the tricyclic scaffolds was based on the 1,3‐dipolar cycloaddition of azomethine ylides, derived from L‐proline and 4‐bromobenzaldehyde, with N‐(4‐fluorobenzyl)maleimide. Introduction of alkyl, alkenyl, and partially fluorinated alkyl residues was achieved upon substitution of a sulfonyl group by mixed Mg/Zn organometallics followed by oxidation/deoxyfluorination, as well as oxidation/reduction/deoxyfluorination sequences. In contrast, the incorporation of perfluoroalkyl groups required a stereoselective nucleophilic addition reaction at the “upper” carbonyl group of the tricycles, thereby yielding scaffolds with an additional OH, F, or OMe group, respectively. All newly prepared inhibitors showed potent biological activity, with inhibitory constants (Ki values) in the range of 0.008–0.163 μM. The X‐ray crystal structure of a protein–ligand complex revealed the exact positioning of a difluoromethyl substituent in the tight P pocket. Fluorophilic characteristics are attributed to this hydrophobic pocket, although the potency of the inhibitors was found to be modulated by steric rather than electronic factors.
Protein‐Structure‐Based Prediction of Animal Model Suitability for Pharmacodynamic Studies of Subtype‐Selective Estrogens

Published: September 2006

AbstractSubtype‐selective estrogens are of increasing importance as tools used to unravel physiological roles of the estrogen receptors, ERα and ERβ, in various species. Although human ERα and ERβ differ by only two amino acids within the binding pockets, we and others recently succeeded in generating subtype‐selective agonists. We have proposed that the selectivity of the steroidal compounds 16α‐lactone‐estradiol (16α‐LE2, hERα selective) and 8β‐vinyl‐estradiol (8β‐VE2, hERβ selective) is based on the interaction of certain substituents of these compounds with essentially one amino acid in the respective ER binding pockets. For in vitro and ex vivo pharmacological experiments with these compounds we intended to use bovine tissues available from slaughterhouses in larger quantities. Using homology modeling techniques we determined that the amino acid conferring high hERβ‐selectivity to 8β‐VE2 is not exchanged between human and bovine ERα and bovine ERβ. Thus, we predicted our steroidal hERβ‐selective compound to exhibit only weak agonistic activity at bERβ and that bovine tissue is therefore not suited for investigation of ERβ functions. The situation is presumably identical for pig, sheep, and the common marmoset, whereas rats, mice, and rhesus macaques are appropriate animal models to study pharmacological effects of 8β‐VE2 in vivo. This prediction was confirmed in transactivation studies assessing estradiol (E2) and the two subtype‐selective ligands on bovine ERβ and on a series of hERα and hERβ with mutations in their respective ligand‐binding pockets. We have shown that the detailed understanding of the interactions of a compound with its target protein enables the identification of relevant species for pharmacological studies.

It considers its formulation, implementation and reformulation and distinguishes conceptual and instrumental approaches coexisting on the landscape. It refers to some challenges in future implementation – especially the link between IPP and sustainable production and consumption (SCP). Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.
Retracted: When nothing compares to me: how defensive motivations and similarity shape social comparison effects
Authors: Stapel Diederik A. , Johnson Camille S. 
Published: September 2006

AbstractWhile similarity typically breeds social comparison, all information gained from social comparisons is not equally influential. Three studies illustrate the situations in which individuals defensively interpret social comparison information such that they incorporate information that reflects positively on the self and disregard negative information. Study 1 extends previous research to show that self‐threat broadens the conditions under which defensive interpretations occur to include those in which similarity is ambiguous. Studies 2 and 3 demonstrate that defensive interpretations are less likely to occur when individuals are affirmed or when the comparison information is unimportant. These findings suggest that the impact of social comparisons on self‐views is determined by both similarity of comparison targets and the motives of the perceiver.

Intergroup structure and identity management among ethnic minority and majority groups: the interactive effects of perceived stability, legitimacy, and permeability
Authors: Verkuyten Maykel , Reijerse Arjan 
Published: September 2006

AbstractThis paper is an examination, in a natural setting, of the interactive effects of perceived stability, legitimacy, and group permeability on group identification, stereotypes, and group feelings among Turkish‐Dutch and ethnically Dutch participants. The findings strongly support predictions derived from the social identity perspective. For the Turkish‐Dutch, a legitimate interethnic structure meant rather unstable relations and permeable group boundaries. For the Dutch, the same structure implied stability and impermeability. For the Turkish‐Dutch, a response pattern of individual mobility was found: if they viewed ethnic intergroup relations as legitimate and stable, permeability was negatively related to Turkish identification as well as to less stereotyping on the dimension defining Turkish identity. It was also related positively to Dutch identification and in‐group bias in relation to other ethnic minority groups. For the Dutch participants, higher perceived legitimacy was associated with stronger in‐group identification and more positive in‐group evaluation. Additionally, in a legitimate context, stability was, for them, related to a lower stereotyping of the Turkish out‐group on status‐relevant dimensions and more negative feelings towards ethnic out‐groups in general.

In Situ Device for Detection of Oil Spill in Seawater
Authors: Abdul‐Wahab Sabah A. 
Published: September 2006

AbstractThe purpose of this study was to design an innovative, real time, cost effective, and environment friendly in situ technique for the surface measurement of oil spill thickness. The technique was based on the concept of the electrical conductivity to characterize and to measure the thickness of an oil layer in seawater. The system was designed to monitor the seawater pollution continuously and to send an alarm if the oil level exceeds a certain limit. The results of this study are very important as they may contribute to the development of advanced practices in oil spill detection.
