Bathymetry based on data recorded during POS317-4 between 16.10.2004 and 04.11.2004. This cruise focused on methane seeps off Georgia and Turkey. Different geological settings were studied by using pressurized sampling techniques and remotely operated vehicles (ROVs).

Mineral composition of 356 sediment profiles from the Arctic seas

This data set contains the mineralogical analyses (binocular counting) of the 100-50 µm grain size fraction from bottom sediments collected by scientists of the V.P. Zenkovich Laboratory of Shelf and Sea Coasts (P.P. Shirshov Institute of Oceanology, Russian Academy of Sciences) during the Project ''Arctic Shelf of the Eurasia in the Late Quaternary'' in a number of expeditions to the Barents, Kara, East Siberian and Chukchi Seas on board research vessels R/V Professor Shtokman, H/V Dmitry Laptev, H/V Malygin, and icebreaker Georgy Sedov between 1978 and 1990. The analyses have been carried out according to the methods published by Petelin V.P. (1961) in the Analytical Laboratory of the P.P. Shirshov Institute of Oceanology. Archiving and electronic publication was performed through a data rescue by Evgeny Gurvich in 2003.

A role for the epithelial-cell-specific tyrosine kinase Sik during keratinocyte differentiation

Sik, the mouse homologue of the breast tumor kinase Brk, is expressed in differentiating cells of the gastrointestinal tract and skin. We examined expression and activity of Sik in primary mouse keratinocytes and a mouse embryonic keratinocyte cell line (EMK). Calcium-induced differentiation of these cells has been shown to be accompanied by the activation of tyrosine kinases and rapid phosphorylation of a 65-kDa GTPase-activating protein (GAP)-associated protein (GAP-A.p65). We demonstrate that Sik is activated within 2 min after calcium addition in primary keratinocytes and EMK cells. In EMK cells, Sik binds GAP-A.p65, and this interaction is mediated by the Sik Src homology 2 domain. Although Sik directly complexes with GAP-A.p65, overexpression of wild-type or kinase defective Sik in EMK cells does not lead to detectable changes in GAP-A.p65 phosphorylation. These data suggest that Sik is not responsible for phosphorylation of GAP-A.p65. GAP-A.p65 may act as an adapter protein, bringing Sik into proximity of an unidentified substrate. Overexpression of Sik in EMK cells results in increased expression of filaggrin during differentiation, supporting a role for Sik in differentiation.

Molecular cloning and characterization of a cellular phosphoprotein that interacts with a conserved C-terminal domain of adenovirus E1A involved in negative modulation of oncogenic transformation.

The adenovirus type 2/5 E1A proteins transform primary baby rat kidney (BRK) cells in cooperation with the activated Ras (T24 ras) oncoprotein. The N-terminal half of E1A (exon 1) is essential for this transformation activity. While the C-terminal half of E1A (exon 2) is dispensable, a region located between residues 225 and 238 of the 243R E1A protein negatively modulates in vitro T24 ras cooperative transformation as well as the tumorigenic potential of E1A/T24 ras-transformed cells. The same C-terminal domain is also required for binding of a cellular 48-kDa phosphoprotein, C-terminal binding protein (CtBP). We have cloned the cDNA for CtBP via yeast two-hybrid interaction cloning. The cDNA encodes a 439-amino acid (48 kDa) protein that specifically interacts with exon 2 in yeast two-hybrid, in vitro protein binding, and in vivo coimmunoprecipitation analyses. This protein requires residues 225-238 of the 243R E1A protein for interaction. The predicted protein sequence of the isolated cDNA is identical to amino acid sequences obtained from peptides prepared from biochemically purified CtBP. Fine mapping of the CtBP-binding domain revealed that a 6-amino acid motif highly conserved among the E1A proteins of various human and animal adenoviruses is required for this interaction. These results suggest that interaction of CtBP with the E1A proteins may play a critical role in adenovirus replication and oncogenic transformation.

Trade policy issues in the Wider Europe – that led to war and not yet to peace. CEPS Working Document No. 398, July 2014

This paper looks at the trade policy landscape of the EU and the wider Europe, with a focus on issues arising from the signature on 27 June 2014 of Deep and Comprehensive Free Trade Agreements (DCFTAs) between the EU and three East European countries (Georgia, Moldova and Ukraine), and actual or prospective issues relating to the customs union of Belarus, Russia and Kazakhstan (BRK), and the Eurasian Economic Union whose founding treaty was signed on 29 May 2014. The huge expansion of intercontinental free trade area negotiations currently underway, in which the EU is an active participant alongside much of the Americas and Asia, stands in contrast with Russia’s choice to restrict itself to the Eurasian Economic Union, which is only a marginal extension of its own economy. Alone among the major economies in the world, Russia does not seek to integrate economically with any major economic bloc, which should be a matter of serious concern for Moscow. Within the wider Europe, the EU’s DCFTAs with Ukraine, Moldova and Georgia are a major new development, but Russia now threatens trade sanctions against Ukraine in particular, the economic case for which seems unfounded and whose unilateral application would also impair the customs union. The Belarus-Russia-Kazakhstan customs union itself poses several issues of compatibility with the rules of the WTO, which in turn are viewed by the EU as an impediment to discussing possible free trade scenarios with the customs union, although currently there are far more fundamental political impediments to any consideration of such ideas. Nonetheless, this paper looks at various long-term scenarios, if only as a reminder that there could be much better alternatives to the present context of conflict around Ukraine.

Composition of bottom sediments from the anoxic Mogil'noe Lake, Kil'din Island (Barents Sea)

In summer 2006 integrated geological, geochemical, hydrological, and hydrochemical studies were carried out in the relict anoxic Mogil'noe Lake (down to 16 m depths) located in the Kil'din Island in the Barents Sea. Chemical and grain size compositions of bottom sediments from the lake (permanently anoxic basin) and from the Baltic Sea deeps (periodically anoxic basins) were compared. Vertical location of the hydrogen sulfide layer boundary in the lake (9-11 m depths) was practically the same from 1974 up to now. Concentrations of suspended matter in the lake in June and July 2006 appeared to be close to its summer concentrations in seawater of the open Baltic Sea. Muds from the Mogil'noe Lake compared to those of the Baltic Sea deeps are characterized by fluid and flake consistency and by pronounced admixtures of sandy and silty fractions (probably of eolic origin). Lacustrine mud contains much plant remains; iron sulfides and vivianite were also found. Concentrations of 22 elements determined in lacustrine bottom sediments were of the same levels as those found here 33 years ago. Concentrations also appeared to be close to those in corresponding grain size types of bottom sediments in the Baltic Sea. Low C_org/N values (aver. 5.0) in muds of the Mogil'noe Lake compared to ones for muds of the Baltic Sea deeps (aver. 10) evidence considerable planktogenic component in organic matter composition of the lacustrine muds. No indications were reveled for anthropogenic contaminations of the lacustrine bottom sediments with toxic metals.

Nicht ob, sondern wie! : die Inklusion von Kindern mit Behinderungen ins deutsche Bildungssystem-­ Fokus Primärbereich

„Auf dem Weg zu einem inklusiven Bildungssystem gemäß der UN-­BRK sind oftmalsdie Barrieren im Kopf das größte Hindernis.“ Bezugnehmend auf diese Aussage derAktion Mensch aus dem Jahr 2014 sind die folgenden Ausführungen an diejenigenadressiert, die nicht das OB fokussieren, sondern die wissen wollen, was sich hinterdem Wie verbirgt. Thematisiert werden grundlegende Begrifflichkeiten sowie aktuelleEntwicklungsstände des inklusiven Schulsystems im Primärbereich. Zudem zielt dieArbeit darauf ab darzulegen, welche Maßnahmen ergriffen werden können undwelche Ressourcen unser Bildungssystem noch bietet, um Schülern mitBeeinträchtigungen ein gleichberechtigtes und erfolgversprechendes Lernsetting zugewährleisten.
