1. The effect ofdietary molybdenum on the growth rate and also on ascorbic acid metabolism in rats was studied. An excess of dietary molybdenum resulted in growth retardation and loss of weight. Tolerance to molybdenum was affected by the nature ofthe molybdenum salt administered. 2. Molybdenum ingestion altered certain aspects of ascorbic acid metabolism in rats. The conversion ofD-glucuronola...

Molybdenum, applied in vivo, restored the damage from low temperature with winter wheat (Triticum aestivum, var "Sadovo 1") grown on acid soil and, in addition, sharply increased productivity (G Salcheva, D Georgieva, 1982; G Salcheva et al., 1977, 1979). Two fractions with molybdenum-cofactor activity in seeds were detected. One of them has a molecular weight of about 230 kilodaltons correspon...

Abstract The titanium alloy Ti–6Al–2Sn–4Zr–2Mo–0.1Si (Ti6242) has been deposited for the first time by a directed energy deposition process using wire and arc system— i.e., wire-arc additive manufacturing (WAAM)—with without inter-pass machine hammer peening, its microstructure investigated compared to more commonly used Ti–6Al–4V (Ti64). application of peening—where each added layer was deform...

Molybdenum reduction to molybdenum blue by microbes is a potential bioremediation tool for molybdenum pollution. A previous work using cyanide as a respiratory inhibitor has shown that the site of molybdenum reduction in Enterobacter cloacae strain 48 is at the electron transport pathway. In the present work, several respiratory inhibitors together with cyanide were used to reinvestigate the si...

In this research, plasma electrolytic oxidation (PEO) coatings were prepared on 7075 Al alloy in a silicate-based solution with Na2MoO4 additive using unipolar waveform at constant current density. The displayed micro-pores, micro-cracks, pancake-like and crater-like features, also solidified molten oxide particles the surface. majorly composed of Al2O3 (γ, δ, α), SiO2 (amorphous), MoO3 phases,...

introduction: the purpose of this preliminary study was to evaluate the periodontal condition of intruded molars in various phases of treatments. methods: 30 patients with at least one overerupted upper first molar were selected. upper molar bands with brackets were cemented. two miniscrews were placed in the mesiopalatal and mesiobuccal aspect of the aforementioned teeth. a titanium molybdenum...
