TY - GEN A1 - Abdollahyan, Hamid T1 - The generations gap in contemporary Iran N2 - This paper offers a new theoretical framework for studying the problem of generations and social change in contemporary Iran. It offers a model which is called „articulation of cultural modes“. The paper agrees with Ronald Inglehart that ‘culture’ is now playing a more dominant role in the social formation of current societies, as ‘technology’ once did in the modern era. But it goes one step further by arguing that culture cannot be approached as a holistic concept building on a comprehensive theoretical framework.

The focus is put on finding nonlinearities within a generalized additive model. These models are found by means of backfitting or more general algorithms, like the alternating conditional expectation value one. The method is illustrated by numerically generated data. As an application, the example of vortex ripple dynamics, a highly complex fluid-granular system, is treated Y1 - 2004 SN - 0218-1274 ER - TY - JOUR A1 - Abetz, Volker A1 - Jiang, S. M.

T1 - Novel pattern formation in blends of asymmetric ABC triblock terpolymers N2 - A series of polystyrene-block-poly(1,2-butadiene)-block-poly(2-vinyl-pyridine) (SBV) triblock terpolymers were used to prepare blends with symmetric polystyrene-block-poly(2-vinylpyridine) (SV) and poly(2-vinylpyridine)-block-poly- (cyclohexyl methacrylate) (VC) diblock copolymers. Morphological characterization was carried out by transmission electron microscopy. These triblock terpolymers self-assemble into various core-shell type or lamellar morphologies. In the SBV/SV blends, macrophase separation between the two block copolymers, continuous centrosymmetric lamellae and stacks of non-centrosymmetric lamellae with anti-parallel orientation were found. In the blends of SBV/VC, macrophase separation was never observed, what is due to the specific interactions between S and C domains. These systems showed among other morphologies also a cylindrical morphology in which rings surround the cylinders Y1 - 2004 SN - 1618-7229 ER - TY - THES A1 - Achsani, Noer Azam T1 - Einfluss der indonesischen Wirtschaftsentwicklung und internationaler Faktoren auf die Jakartaer Börse : statistische Analyse und ökonometrische Modellierung Y1 - 2004 SN - 3-8325-0775-2 PB - Logos Verl.

However, Glg2p possesses an additional tyrosine residue, Tyr230 and therefore two potential autoglucosylation sites. Glucosylation of Glg2p was studied using both matrix-assisted laser desorption ionization and electrospray quadrupole time of flight mass spectrometry. Glg2p, carrying a C-terminal (His(6)) tag, was produced in Escherichia coli and purified. By tryptic digestion and reversed phase chromatography a peptide (residues 219-246 of the complete Glg2p sequence) was isolated that contained 4-25 glucosyl residues. Following incubation of Glg2p with UDPglucose, more than 36 glucosyl residues were covalently bound to this peptide. Using a combination of cyanogen bromide cleavage of the protein backbone, enzymatic hydrolysis of glycosidic bonds and reversed phase chromatography, mono- and diglucosylated peptides having the sequence PNYGYQSSPAM were generated. MS/MS spectra revealed that glucosyl residues were attached to both Tyr232 and Tyr230 within the same peptide. The formation of the highly glucosylated eukaryotic Glg2p did not favour the bacterial glycogen accumulation. Under various experimental conditions Glg2p-producing cells accumulated approximately 30% less glycogen than a control transformed with a Glg2p lacking plasmid. The size distribution of the glycogen and extractable activities of several glycogen-related enzymes were essentially unchanged. As revealed by high performance anion exchange chromatography, the intracellular maltooligosaccharide pattern of the bacterial cells expressing the functional eukaryotic transgene was significantly altered. Thus, the eukaryotic glycogenin appears to be incompatible with the bacterial initiation of glycogen biosynthesis Y1 - 2004 ER - TY - JOUR A1 - Ale-Agha, Nosratollah A1 - Bolay, Adrien A1 - Braun, Uwe A1 - Jage, Horst A1 - Kummer, Volker A1 - Lebeda, Ales A1 - Piatek, Marcin A1 - Shin, Hyeon-Dong A1 - Zimmermannova-Pastircakova, Katarina T1 - Erysiphe catalpae and E. elevata in Europe Y1 - 2004 ER -
