Molten chloride salt is recognized as a promising heat transfer and storage medium in concentrating solar power recent years, but there serious lack for thermal property data of molten salts. In this work, local structures properties salt—including NaCl, MgCl2, ZnCl2—were precisely simulated by Born–Mayer–Huggins (BMH) potential rigid ion model (RIM) polarizable (PIM). Compared with experimenta...

ECM protein enrichment and immunoblotting 100mg of frozen samples were homogenized using a polytron (Kinematica, Bohemia, NY) in 250μL of buffer C (HEPES pH7.9, MgCl2, KCl, EDTA, Sucrose, Glycerol, Sodium OrthoVanadate) of the CNMCS protein extraction kit. Lysates were then spun for 20 min. at 15,000 rpm at 4°C, the supernatant was saved (intermediate fraction 1, enriched for cytosolic proteins...

We have examined binding of the CREB B-ZIP protein domain to double-stranded DNA containing a consensus CRE sequence (5'-TGACGTCA-3'), the related PAR, C/EBP and AP-1 sequences and the unrelated SP1 sequence. DNA binding was assayed in the presence or absence of MgCl2 and/or KCl using two methods: circular dichroism (CD) spectroscopy and electrophoretic mobility shift assay (EMSA). The CD assay...

The influence of Ca2+ on the enzymatic and physical properties of smooth muscle myosin was studied. The actin-activated ATPase activity of phosphorylated gizzard myosin and heavy meromyosin is higher in the presence of Ca2+ than in its absence, but this effect is found only at lower MgCl2 concentrations. As the MgCl2 concentration is increased, Ca2+ sensitivity is decreased. The concentration o...

The small oligomers formed from Mg-G-actin under favorable conditions were studied by sedimentation velocity ultracentrifugation. The critical concentration of actin at pH 7.8 in the presence of 100 microM MgCl2 and 200 microM ATP was 12.5 +/- 2.8 microM. Under these conditions, about 15% of 7.5 microM Mg-actin was converted to oligomers of subunit size four to eight in 5 h at 20 degrees C. In ...

behaviors of stress corrosion cracking (scc)in martensitic stainless steel(aisi 420) and low carbon austenitic stainless steel (aisi 316l) have been compared under different conditions of temperature, environment (mgcl2), and strain rate. the results show that decreasing strain rate has detrimental effect on mechanical properties of both steels, including their strength and ductility. fractogra...

This paper was aimed to study the efficiency of forward osmosis (FO) process as a new application for treatment wastewater from textile effluent and factors affecting performance process.The draw solutions used were magnesium chloride (MgCl2), aluminum sulphate (Al2 ( SO4)3 .18 H2O), feed reactive red, disperse blue dyes.Experimental work includes operating using thin film composite (TFC) membr...

L-phenylalanine was produced by genetically modified bacterium, Escherichia coli BL21(DE3), using glycerol as an alternative carbon source. Response surface methodology (RSM) involving central composite design (CCD) was adopted to evaluate the amount of L-phenylalanine produced. In this work, the optimum concentrations were determined of the major nutrients in the fermentation medium, which inc...

In this contribution we used solid state 35Cl (I=3/2) quadrupolar NMR to study a MgCl2/2,2-dimethyl-1,3-dimethoxypropane (DMDOMe) adduct that serves as a model system for Ziegler-Natta catalysis. Employing large Radio-Frequency (RF) field strengths we observe three spectral features with strongly varying line widths. The assignment of the spectra is complicated because of the large difference i...
