In this article, we present Tellurium, a powerful Python-based integrated environment designed for model building, analysis, simulation and reproducibility in systems and synthetic biology. Tellurium is a modular, cross-platform, and open-source integrated development environment (IDE) composed of multiple libraries, plugins, and specialized modules and methods. Tellurium ensures exchangeabilit...

a simple, rapid and sensitive method has been developed for determination of trances of tellurium (vi) (0.096-1.250 mg/ml) based on its catalytic effect on the reduction reaction of toluidine blue by sulfide ion at ph 4. the reaction is monitored spectrophotometrically by measuring the decrease in absorbance of the dyestuff at 628 nm by the fixed time method. the detection limit is 80 ng/ml and...

Exposure of weanling rats to a diet containing the element tellurium results in specific inhibition of squalene epoxidase, an obligate enzyme in cholesterol biosynthesis. Liver responds to the resulting intracellular sterol deficit by up-regulating, in parallel and to the same extent, expression of mRNA for squalene epoxidase and for HMG-CoA reductase, the major rate-limiting enzyme in the path...

When the former method is employed for production, enriched uranium irradiated for 2-3 weeks in the nuclear reactor is dissoivoc! in nitric acid and the iodine-131 is distilled and collected. '*) But separation of iodine-1 31 from pile irradiated tellurium targets is the most commonly used method of production. The methods <d Reparation varies for different targets. With metal tellurium the tar...

IV-VI semiconductor quaternary alloys lattice matched with BaF2 substrates have been grown by liquid phase ,epitaxy. X-ray diffraction analysis shows that liquid (Pbl-,~Sn,L)0.99(Sel--YLTe~L)0.01 solutions produce Pbt -+Sn,,Ser -rsTey, alloys lattice matched with the substrate when yL=60%, SS%, and 57%, and x,=20%, 40%, and 60%, respectively. These data, which can be used to fabricate lattice-m...

Bius, Janet Horton, Developing a Method for Determining the Mass Balance of Selenium and Tellurium Bioprocessed by a Selenium-Resistant Bacterium Grown in the Presence of Selenite or Tellurite, Master of Science (Chemistry), December, 2001. Sam Houston State University, Huntsville, Texas, 68 pp. Purpose The purpose of this investigation was to determine: (1) the mass balance of selenium or tell...

A new tellurium-substituted Lindqvist-type polyoxoniobate [H2TeNb5O19](5-) was synthesized as a tetramethylammonium salt. When irradiated with a Xe lamp, a water-methanol solution of this cluster showed exceptionally high H2-evolution activity suggesting cocatalysis by the hexaniobate cluster and metallic tellurium, both of which are formed as photodecomposition products.
