cat-86 is a promoter-deficient plasmid gene that encodes chloramphenicol acetyltransferase (CAT). Insertion of a promoter at a site 144 base pairs 5' to the cat-86 coding sequence activates transcription of the gene and allows cat-86 to specify chloramphenicol-inducible CAT activity in Bacillus subtilis. Induction of cat-86 by chloramphenicol has been shown to result from a regulatory event tha...
This work is mainly concerning with effects of Carbon, Nickel and vanadium on mechanical properties low alloy wear resistant steel. the results showed that The experimental steels yielded their best comprehensive at 940 °C quenching 200 tempering for 0.33 wt% C steel, 220°C 0.38 920°C 230 0.4 respectively.3% Ni steel property 900 tempering, while 5% was 920 tempering. Vanadium addition

Silicon Graphics’ popular Indy workstation line will get a big boost from the R5000 processor, due this spring. The new chip, a follow-on to the Orion design, combines improved integer speed with strong floating-point performance for a midrange processor. At 200 MHz, the R5000 is expected to deliver better than 5.2 SPECint95 and 5.2 SPECfp95 in initial systems. The compact design fits into just...
To investigate the vascular endothelial dysfunction in the insulin resistance syndrome, muscarinic and alpha2-adrenergic mediated relaxations were studied in the fructose-fed rat. Male Sprague-Dawley rats were fed either fructose-rich chow (FFR, n=14) or normal chow (CNT, n=13) for 8 weeks. Systolic blood pressure (SBP) was measured by the tail-cuff method. A 3 mm segment of mesenteric artery w...
This study aims to determine the effect of hardening and tempering on tensile strength (ASTM E 8) hardness (Rockwell) applied medium carbon steel. The heat treatment process is heated by a furnace at temperature 900 °C 920 then held for 30 minutes cooled quickly further processed Tempering with each being tempered 500 slowly. results obtained are in variation °C, value increases from raw materi...
We demonstrate nonvolatile storage of femtosecond pulses in a photorefractive LiNbO(3) crystal with recording and readout of spectral holograms at wavelengths of 460 and 920 nm, respectively. No degradation was observed after 24 h of continuous readout. We also show that we can realize the time-lens effect with our system by appropriately setting the ratio of the recording and the reconstructio...
We report on a search for the flavor-changing neutral current decay D0 → μ+μ− using 50 × 106 events recorded with a dimuon trigger in interactions of 920 GeV protons with nuclei by the HERA-B experiment. We find no evidence for such decays and set a 90% confidence level upper limit on the branching fraction B(D0 →μ+μ−) < 2.0 × 10−6. 2004 Elsevier B.V. All rights reserved. PACS: 13.20.Fc; 14.4...
