The intermetallic compound MoSi2, which adopts the C11b crystal structure, and related alloys exhibit an excellent corrosion resistance at high temperatures but tend to be brittle at room and even relatively high temperatures. The limited ductility of MoSi2 in ambient conditions along with the anomalous temperature dependence of the critical resolved shear stress (CRSS) of the {110)<111], {011)...

Coating a MoSi2 ceramic layer on Mo substrates is an excellent strategy to enhance their oxidation resistance at elevated temperatures. Suppressing elemental interdiffusion across the Mo/MoSi2 interface very important for extending service life of substrates. The present study attempted develop WMoNbVTa high-entropy alloy (HEA) as diffusion barrier interface. A new double-layer WMoNbVTa/MoSi2 c...

Recombinant mouse interleukin 10 (IL-10) was exceedingly potent at suppressing the ability of mouse peritoneal macrophages (mOb) to release tumor necrosis factor a (TNF-o~). The ICs0 of IL-10 for the suppression of TNF-ol release induced by 0.5 #g/ml lipopolysaccharide was 0.04 _+ 0.03 U/ml, with as little as 1 U/ml suppressing TNF-ot production by a factor of 21.4 + 2.5. At 10 U/ml, II.-10 mar...

The diversity of cultivable methane-oxidizing bacteria (MOB) in the rice paddy field ecosystem was investigated by combined culture-dependent and fluorescence in situ hybridization (FISH) techniques. Seven microsites of a Japanese rice paddy field were the focus of the study: floodwater, surface soil, bulk soil, rhizosphere soil, root, basal stem of rice plant, and rice stumps of previous harve...

BACKGROUND A month-of-birth (MOB) effect has been shown in multiple sclerosis (MS). METHODS Our chi(2) analyses looked at whether this MOB effect differed by MS phenotype ("bout onset," "primary progressive"). RESULTS The MOB effect was derived from "bout onset" MS patients (May/November ratio = 1.43; chi(2) = 17.32, df = 1, p = 0.000032). CONCLUSIONS An unspecified environmental effect i...
