Interstorage of AVR-Fuels in the Research-Center

Between 26.08.1966 and 31.12.1988 the experimental nuclear power plant AVR was operated in the area of the Juelich research-center by the Arbeitsgemeinschaft Versuchs-Reaktor mbH, the AVR company. This plant was a Helium cooled high-temperature-reactor with an electric gross-power of 15 MW. This type of power plant was the first one being developed exclusively in Germany. The high-temperature-reactor AVR was one after the principle of the ball-pile-reactor developed by Professor Schulten. The core consists of spherical, graphite fuels with 60 mm diameter, that contain the fissile-material and breed-material in form of coated particles. The fuel is enclosed by a cylindrical graphite-construction which serves as the neutron-reflector. The coating of the fuel-particles consist of pyro-carbon and silicon-carbide and is used for the retention of the fission-products. The reactor has continuously been refueled by feeding the fuel balls into the core at the top and discharging them at the bottom during full operation. After the shut down the reactor now is on the way to safe closure while plans for dismantling have been started. The Juelich research-center was engaged with the storage of the spent fuels as part of the fuel management. The storage of the fuel in CASTOR{reg_sign} THTR/AVR casks is preceded by different actions, like the removal of the fuel from the reactor core, the interim storage of the fuel in AVR-cans in the buffer-storage, decanting of the fuel balls from AVR-cans in the dry-storage-cans (TLK), the interim storage of the TLK, welding of the TLK which contain wet fuel and the loading of each CASTOR{reg_sign} THTR/AVR cask with two TLKs, are necessary. The action is taken at different locations in the research-center. The steps of the fuel management are described in the following

Success Outcome Markers in Extension (SOME): Evaluating the Effects of Transformational Learning Programs

Success outcome markers (SOMs), and the process of creating them, offer Extension a new approach to plan, monitor, and evaluate programs. Generating success outcome markers helps to carefully determine all partners (including beneficiaries) who may need to change to accomplish program goals and identifies steps to continuously track incremental successes. Hard-to-measure human behaviors become more concrete when success outcome markers are listed. To successfully use SOMs, one must (a) create a vivid and compelling vision, (b) list your WHOs, (c) write an outcome challenge for each WHO, and (d) determine SOMs. Then decide how to monitor and report on each SOM

Étude comparative du conte de Charles Perrault, « Le petit Chaperon rouge », en français et de deux traductions en espagnol. Problèmes de traduction et tendances constatées

La complejidad es seguramente lo que mejor define la traducción literaria en general y la traducción de la literatura infantil en concreto, de ahí la aparición de diversos trabajos de búsqueda sobre la teoría y la práctica de la traducción, que incluso han llevado al nacimiento de una nueva ciencia, la traductología. El cuento de Charles Perrault, “Le petit Chaperon rouge” (La Caperucita Roja), es el ejemplo mismo de una obra literaria para niños que ha dado la vuelta al mundo. Un análisis detallado de este cuento demuestra que es más complejo de lo que parece, tanto en la extensión de sus significados posibles, como en su expresión artística. La comparación del texto inicial de Charles Perrault publicado en 1697 con dos traducciones en español realizadas por Terodoro Baró en 1883 y por Leonardo Domingo en 2003 pondrá en evidencia las modificaciones realizadas que pueden explicarse especialmente por el contexto histórico o lingüístico de cada traductor. Comprobaremos asimismo que, si bien globalmente el relato de La Caperucita Roja es respectado, se pierde una parte de la complejidad del cuento por razones que debemos intentar explicar

Biosynthesis of mycobacterial arabinogalactan: identification of a novel (13)arabinofuranosyltransferase

The cell wall mycolyl-arabinogalactan-peptidoglycan complex is essential in mycobacterial species, such as Mycobacterium tuberculosis and is the target of several anti-tubercular drugs. For instance, ethambutol targets arabinogalactan biosynthesis through inhibition of the arabinofuranosyltransferases Mt-EmbA and Mt-EmbB. A bioinformatics approach identified putative integral membrane proteins, MSMEG2785 in Mycobacterium smegmatis, Rv2673 in Mycobacterium tuberculosis and NCgl1822 in Corynebacterium glutamicum, with 10 predicted transmembrane domains and a glycosyltransferase motif (DDX), features that are common to the GT-C superfamily of glycosyltransferases. Deletion of M. smegmatis MSMEG2785 resulted in altered growth and glycosyl linkage analysis revealed the absence of AG (13)-linked arabinofuranosyl (Araf) residues. Complementation of the M. smegmatis deletion mutant was fully restored to a wild type phenotype by MSMEG2785 and Rv2673, and as a result, we have now termed this previously uncharacterized open reading frame, arabinofuranosyltransferase C (aftC). Enzyme assays using the sugar donor -D-arabinofuranosyl-1-monophosphoryldecaprenol (DPA) and a newly synthesized linear (15)-linked Ara5 neoglycolipid acceptor together with chemical identification of products formed, clearly identified AftC as a branching (13) arabinofuranosyltransferase. This newly discovered glycosyltransferase sheds further light on the complexities of Mycobacterium cell wall biosynthesis, such as in M. tuberculosis and related species and represents a potential new drug target

Identification and structural characterisation of a partially arabinosylated lipoarabinomannan variant isolated from a Corynebacterium glutamicum ubiAmutant

Arabinan polysaccharide side-chains are present in both Mycobacterium tuberculosis and Corynebacterium glutamicum in the heteropolysaccharide arabinogalactan (AG), and in M. tuberculosis in the lipoglycan, lipoarabinomannan (LAM). Herein, we show by quantitative sugar and glycosyl linkage analysis that C. glutamicum possesses a much smaller LAM version, Cg-LAM, characterised by single t-Araf residues linked to th
