The effect of Mw on the non-isothermal crystallization kinetics of metallocene linear polyethylene (m-PE) was studied using modulated differential scanning calorimetry. Six linear m-PEs of molecular weights in the range 122-934 kg/mol were prepared by gas phase polymerization. The cooling rate was varied in the range 2–20C/min and it has significantly affected the crystallization behavior. The ...

The molecular weight (MW) of a protein can be predicted based on its amino acids (AA) composition. However, in many cases a non-chemically modified protein shows an SDS PAGE-displayed MW larger than its predicted size. Some reports linked this fact to high content of acidic AA in the protein. However, the exact relationship between the acidic AA composition and the SDS PAGE-displayed MW is not ...

lidocaine (lc) is a local anesthetic agent. the aim of this study was to prolong the anesthetic effect of this drug in the oral cavity in the treatment of oral mucositis. films of lc were prepared with three different molecular weights (mw) of chitosan in three different concentrations (1-3%) and were then cross-linked by solvent casting evaporation method with tripolyphosphate penta sodium sal...

The molecular weight (MW) of Sindbis virion ribonucleic acid (RNA) determined by gel electrophoresis was in a range of 3.89 x 10(6) to 4.45 x 10(6) daltons. Upon denaturation with urea, it separated into fragments having an MW of 1.76 x 10(6) daltons. Viral-specific Sindbis 26S RNA contained a major species having an MW of 1.76 x 10(6) daltons.

Today’s Microwave ovens are often equipped with inverterized MW generators; compared with old style appliances, the magnetron is no more driven by a bulky ferro-resonant power supply, but by an electronic inverter, lighter, more efficient and, moreover, able to modulate the MW power, at least to a certain extent. The electronic power supply is generally designed around a resonant inverter which...

We present the currently most accurate evaluation of the W boson mass, MW , in the Minimal Supersymmetric Standard Model (MSSM). The full complex phase dependence at the one-loop level, all available MSSM two-loop corrections as well as the full Standard Model result have been included. We analyse the impact of the different sectors of the MSSM at the one-loop level with a particular emphasis o...

The spherical tokamak (ST) regime of low-aspect-ratio (LAR) tokamak operation has provided an opportunity to consider a 1000-MWe(net) D /T power plant conceptual design, designated ARIES-ST. Physics attributes include high beta ( /50%) together with high bootstrap current contribution ( /95%). Neutral-beam current drive ( /28 MW) supports steady-state operation. The plasma aspect ratio was sele...

We investigated genetic associations between mature cow weight (MW) and weaning weight (WW), yearling weight (YW), weight gain from birth to weaning (GBW), weight gain from weaning to yearling (GWY), weaning hip height (WHH), yearling hip height (YHH), scrotal circumference (SC), and age at first calving (AFC). Data from 127,104 Nellore animals born between 1993 and 2006, belonging to Agr...

The effect of bentonite fining on the total proteins and the heat-unstable (80°C, 6 h; 4°C, 12 h) proteins in GewLirztraminer, White Riesling, Sauvignon blanc, and Sylvaner wines was investigated. Protein molecular weights (MW), isoelectric points (pl), and glycoproteins were determined by using lithium dodecyl sulfate polyacrylamide gel electrophoresis (LDS PAGE) and two-dimensional isoelectri...
