We investigated the alloy composition of Mg-Ca-Zn alloys suitable for rapidly solidified powder metallurgy (RS PM) processing and tried to develop biomedical RS PM with high strength, ductility, corrosion resistance. The was Mg-1.0Ca-0.5Zn (at%) in ternary alloys. An combined additions 0.1 at% Y 0.03 Mn exhibited excellent performance a tensile yield strength 376±17 MPa, an elongation 14.1±3.1%...

Yogurt, a traditional Turkish dairy product is common in all region of Turkey. The different heavy metals were determined in commercial yogurts by inductively coupled plasma optical emission spectrometer (ICP–OES). Concentrations of calcium (Ca), phosphorus (P), sodium (Na), magnesium (Mg), aluminum (Al), zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), boron (B), molybdenum (Mo), cadmium (Cd...

BACKGROUND Previous studies indicated that the iron (Fe)/manganese (Mn) ratio in forage of sheep was significantly higher on scrapie-afflicted farms than on farms in other scrapie categories. This study was conducted to examine whether Fe and Mn in forage of sheep varied in general according to the scrapie status of different areas in the country. Copper (Cu) and zinc (Zn) were also included be...

zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. ...

At physiological pH and concentrations of Mn(++) in excess of 5 x 10(-4)M, study of the Mn(++) ion movement into human red cells is complicated by physicochemical alterations of the ion itself. At concentrations below 5 x 10(x4)M, the rate of uptake bears a linear relationship to the Mn(++) concentration. The permeability constant for inward movement of Mn(++) is 2.87 +/- 0.13 (S.E.) x 10(-9) c...

This study was aimed at investigating the bioefficacy of organic compared with inorganic manganese (Mn) for eggshell quality. An amino acid-Mn complex or Mn sulfate monohydrate was used as the organic or inorganic Mn source. A total of six hundred forty-eight 50-wk-old layers (Hy-Line Brown) were divided into 9 groups; each group consisted of 6 replicates with 12 layers each. The feeding trial ...

The objective of this study was to compare the effects of feed supplementation of laying hens with manganese from its inorganic and organic sources on performance and some parameters of egg quality. Ninety-six hens at 20 weeks of age were randomly allocated to 4 dietary treatments, each consisting of 6 replicates (4 birds per replicate). The control group was fed unsupplemented basal diet (BD) ...

The kinetics of Mn(II) oxidation by the bacterium Leptothrix discophora SS1 was investigated in this research. Cells were grown in a minimal mineral salts medium in which chemical speciation was well defined. Mn(II) oxidation was observed in a bioreactor under controlled conditions with pH, O2, and temperature regulation. Mn(II) oxidation experiments were performed at cell concentrations betwee...
