New Inner Canalizing Technology with Vapour Hardening Material

The Liner is a composite sandwich construction using multiple layers of Owens Corning Advantex extra corrosion resistant fiberglass, forming a complex unidirectional reinforced structure. This construction achives an unmatched strenght permitting a thinner wall and therefore less reduction of the original diameter. The ring stiffness is very important. The unique design of the Liner gives a very high E-Moduls performance of 10.000 MPa which is unmatched by any other liner on the market. The longitudial reinforcement ensures complete stability troughout the length and prevent any elongation caused by the installation process. The Liner is constructed using extra corrosion resistant fiberglass. The inside of the liner is covered with a polyester veil rich of resin, forming a very smooth and glass-hard surface. In Combination with the unique post-curing at 110 °C, a very high resistance to abrasion and chemicals is achieved

Goldmann, Julia ;Edmund Wachs was born November 12th 1908 and grew up in Vienna, where he worked in sausage manufacturing. After his four months imprisonment as a “Schutzhaeftling” in the “Polizeigefaengnis Rossauer Kaserne” in 1938, he married Berta Goldmann, and escaped to Anvers, Belgium, from where he planned his immigration to the US. In 1939 he finally left Europe with the help of false papers and a ship bound for New York.Berta Wachs née Goldmann was born on October 10th 1914 in Vienna. She studied at the “Hochschule fuer Welthandel” (University of Economics and Trade) for one year and then worked for different companies as a correspondent. She left Europe in 1939.

Interdisciplinary Cooperation in the Exploration of appropriate sites for the Radioactive Waste Deposition

The article deals with the interdisciplinary cooperation in the processes of exploration of appropriate sites for radioactive waste deposits. This work is based on trends in the environmental laws for radioactive wastes. For the exploration, a knowledge about the geological structures, properties of rocks and safety manipulation with radioactive wastes are necessary. The interdisciplinary cooperation is needed with geophysics to define the particularly hazardous areas of an earthquake shaking. In this article, a method of the seismic analysis by Ricker impuls and Gabor´s function are presented

A second branched-chain alpha-keto acid dehydrogenase gene cluster (bkdFGH) from Streptomyces avermitilis: its relationship to avermectin biosynthesis and the construction of a bkdF mutant suitable for the production of novel antiparasitic avermectins.

A second cluster of genes encoding the E1 alpha, E1 beta, and E2 subunits of branched-chain alpha-keto acid dehydrogenase (BCDH), bkdFGH, has been cloned and characterized from Streptomyces avermitilis, the soil microorganism which produces anthelmintic avermectins. Open reading frame 1 (ORF1) (bkdF, encoding E1 alpha), would encode a polypeptide of 44,394 Da (406 amino acids). The putative start codon of the incompletely sequenced ORF2 (bkdG, encoding E1 beta) is located 83 bp downstream from the end of ORF1. The deduced amino acid sequence of bkdF resembled the corresponding E1 alpha subunit of several prokaryotic and eukaryotic BCDH complexes. An S. avermitilis bkd mutant constructed by deletion of a genomic region comprising the 5' end of bkdF is also described. The mutant exhibited a typical Bkd- phenotype: it lacked E1 BCDH activity and had lost the ability to grow on solid minimal medium containing isoleucine, leucine, and valine as sole carbon sources. Since BCDH provides an alpha-branched-chain fatty acid starter unit, either S(+)-alpha-methylbutyryl coenzyme A or isobutyryl coenzyme A, which is essential to initiate the synthesis of the avermectin polyketide backbone in S. avermitilis, the disrupted mutant cannot make the natural avermectins in a medium lacking both S(+)-alpha-methylbutyrate and isobutyrate. Supplementation with either one of these compounds restores production of the corresponding natural avermectins, while supplementation of the medium with alternative fatty acids results in the formation of novel avermectins. These results verify that the BCDH-catalyzed reaction of branched-chain amino acid catabolism constitutes a crucial step to provide fatty acid precursors for antibiotic biosynthesis in S. avermitilis
