The galactose cluster is obtained by Koenigs-Knorr glycosylation of TRIS-Gly-Fmoc (2b) under Helferich conditions. Peptide and ester bonds are formed after activation of carboxylic acids as diphenylthiophene dioxide (TDO) esters. 6a is synthesized in a convergent way by coupling of (Ac4Gal)3-TRIS-Gly (3e) with cholesteryl TDO succinate (5b). Coupling of (Ac4Gal)3-TRIS-Gly hydrogen succinate (3f) with Gly-O-Chol (5d) by means of EEDQ yields 6d. Reaction of (Ac4Gal)3-TRIS-Gly-SUCC-O-TDO (3g) with 25-hydroxycholesterol leads in a linear sequence to the oxysterol derivative 6f. Selective cleavage of the acetyl groups from galactose units yields the known compound 6b and the new derivatives 6e and 6g.

Vor diesem Hintergrund wurde gemeinsam mit dem Institut für Schulqualität Berlin-Brandenburg auf der Grundlage von realen VERA-Ergebnissen die „VERA-Box“ entwickelt. Die Lerngelegenheit soll Erwartungen und Werte von Lehrkräften im Umgang mit Ergebnissen standardisierter Testverfahren, deren Absicht, Unterricht zukünftig unter Bezug auf solche Testergebnisse zu entwickeln, sowie den differenziellen Nutzen dieser Rückmeldeinformationen stärken. Es wurde experimentell variiert, ob zusätzlich entweder die Aufforderung enthalten war, die Relevanz standardisierter Daten für die spätere Lehrtätigkeit zu reflektieren, oder sich mit negativen Argumentationen zu VERA auseinanderzusetzen. An drei Stichproben von insgesamt 763 Lehramtsstudierenden wurde die „VERA-Box“ über drei Semester erprobt und die Wirksamkeit evaluiert. Die Ergebnisse zeigen, dass die Intention, VERA-Rückmeldungen für die eigene Unterrichtsentwicklung zu nutzen, vom ersten zum zweiten Messzeitpunkt in allen Kohorten signifikant gestärkt wurde.

The motivation of this research is that although there are difficult issues that require technical backgrounds, students are already familiar with demanding computational problems through games such as Sudoku or Tetris. Our intention is to bring together important concepts in the theory of NP completeness in such a way that students in secondary schools can easily understand them. This is part of our ongoing research about how to teach fundamental issues in Computer Science in secondary schools. We discuss what needs to be taught in which sequence in order to introduce ideas behind NP completeness to students without technical backgrounds.

Technocrats are described as experts without morals, able to function in any kind of political system. Nevertheless one should remember that the technocratic idea contained from the very beginning a strong ethic element: conventional political power as an instrument of repression should be replaced by the rule of sciences as an instrument to improve human life. Although the idea of eliminating politics by "science-based" decisions of an autocratic leadership has been widely used to legitimate totalitarian rule, it is obvious, that clear technocratic reasoning and decision making do not go conform with the functioning of a totalitarian system. On the contrary, technic and technologic innovation accelerated the breakdown of totalitarianism. The complex character of modern societies calls for regulation by markets and pluralistic political systems. The evolution of our technical civilization improved the conditions for democratic selforganisation.

The strings are collected into regular languages to ensure the decidability of entailments given by inclusions between languages. (Various notions of bounded entailment are shown to be expressible as language inclusions.) The languages unwind computations implicit in the logical (and temporal) connectives via a system of finite-state constraints adapted from finite-state morphology. Applications to Hybrid Logic and non-monotonic inertial reasoning are briefly considered.

Unfortunately informatics curricula, which include the domain of logic programming, are still input-orientated or lack detailed competence descriptions. Therefore, the development of competence model and of learning outcomes' descriptions is essential for the learning process in this domain. A prior research developed both. The next research step is to formulate test items to measure the described learning outcomes. This article describes this procedure and exemplifies test items. It also relates a test in school to the items and shows which misconceptions and typical errors are important to discuss in class. The test result can also confirm or disprove the competence model. Therefore, this school test is important for theoretical research as well as for the concrete planning of lessons. Quantitative analysis in school is important for evaluation and improvement of informatics education.

Experts with different backgrounds starting to work together need more opportunities for information exchange to improve mutual understanding and cooperation. The Conference "Physics and Control 2007" is the third international conference focusing on the borderland between Physics and Control with emphasis on both theory and applications. With its 2007 address at Potsdam, Germany, the conference is located for the first time outside of Russia. The major goal of the Conference is to bring together researchers from different scientific communities and to gain some general and unified perspectives in the studies of controlled systems in physics, engineering, chemistry, biology and other natural sciences. We hope that the Conference helps experts in control theory to get acquainted with new interesting problems, and helps experts in physics and related fields to know more about ideas and tools from the modern control theory.

L. A1 - Prinja, R. K. A1 - Fullerton, A. W. T1 - The effects of clumping on wind line variability N2 - We review the effects of clumping on the profiles of resonance doublets. By allowing the ratio of the doublet oscillator strenghts to be a free parameter, we demonstrate that doublet profiles contain more information than is normally utilized. In clumped (or porous) winds, this ratio can lies between unity and the ratio of the f-values, and can change as a function of velocity and time, depending on the fraction of the stellar disk that is covered by material moving at a particular velocity at a given moment. Using these insights, we present the results of SEI modeling of a sample of B supergiants, ζ Pup and a time series for a star whose terminal velocity is low enough to make the components of its Si VIλλ1400 independent. These results are interpreted within the framewrok of the Oskinova et al. (2007) model, and demonstrate how the doublet profiles can be used to extract infromation about wind structure.

After briefly reviewing its importance, we discuss the impact of the recently proposed downward revision of mass loss rates due to clumping (difficulty to form Wolf-Rayet stars and production of critically rotating stars). Although a small reduction might be allowed, large reduction factors around ten are disfavoured. We then discuss the possibility of significant mass loss at very low metallicity due to stars reaching break-up velocities and especially due to the metal enrichment of the surface of the star via rotational and convective mixing. This significant mass loss may help the first very massive stars avoid the fate of pair-creation supernova, the chemical signature of which is not observed in extremely metal poor stars. The chemical composition of the very low metallicity winds is very similar to that of the most metal poor star known to date, HE1327-2326 and offer an interesting explanation for the origin of the metals in this star. We also discuss the importance of mass loss in the context of long and soft gamma-ray bursts and pair-creation supernovae. Finally, we would like to stress that mass loss in cooler parts of the HR-diagram (luminous blue variable and yellow and red supergiant stages) are much more uncertain than in the hot part. More work needs to be done in these areas to better constrain the evolution of the most massive stars. Y1 - 2007 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:517-opus-17616 ER -
