The Escherichia coli araBAD operon consists of three genes encoding three enzymes that convert L-arabinose to D-xylulose-5 phosphate. In this paper we report that the genes of the E. coli araBAD operon have been expressed in Saccharomyces cerevisiae using strong promoters from genes encoding S. cerevisiae glycolytic enzymes (pyruvate kinase, phosphoglucose isomerase, and phosphoglycerol kinase)...

Pornind de la o interesantă decizie a Curții Apel Timișoara, în cuprinsul acestui material fost analizată ipoteza care un angajator achită anumite sume bani angajaților își desfășoară temporar activitatea pe teritoriul unui alt stat membru, cu titlu diurnă. Astfel, au trecute revistă argumentele invocate Tribunalul Arad și Curtea Timișoara prin s-a decis că se impune achitarea inculpatului, dar...

in this research by taking advantage of degradtion model ina grid system an area of 9222 km in eastern part of tehran province including eslam shahr , rey , varamin , damavand , and firooz kooh were studied . the results show that 43.8 % of the area , due to its natural condition , is not suitable for development. the rest of the area ( 42.5) due to the degradation caused by man's activiti...

The reactivity of the Cu(II) complex N,N’-bis(pyridin-2-ylmethylene)propane-1,3-diamine (py2pn), [Cu(py2pn)(ClO4)2], toward O2.− and H2O2 has been examined. reacts with fast second order kinetics, kMcF=4.05×106 M−1 s−1, employing Cu(II)/Cu(I) couple proved by spectroscopic detection reduced form at low temperature. At −40 °C in DMF, reaction H2O2/Et3N yields an stable end-on Cu(II)-hydroperoxid...

With an aging population, renovascular hypertension has become a major public health problem (Safian & Textor, 2001). Although various forms of fibromuscular disease of the renal arteries and/or traumatic disruption of renal vessels are the most common cause of RVH among the younger individuals, atherosclerotic renal artery disease (ARAD) is the most common lesion producing hypertension by far ...

Abstract The fundamental pillars of the emerging European integrated railway area include improving safety rail transport and quality parameters lines ensuring their interoperability. As is one safest systems most environmentally friendly, Slovak Railways (ŽSR) have developed strategic investment plans to increase competitiveness in relation other modes transport. current modernisation or recon...

We consider random translation-invariant frustration-free quantum spin Hamiltonians on $\mathbb Z^D$ in which the nearest-neighbor interaction every direction is randomly sampled and then distributed across lattice. Our main result that, under a small rank constraint, are automatically they gapped with positive probability. This extends previous results 1D chains to all dimensions. The argument...
