Monazite [(Ce,Th)PO4] from the Llallagua tin ore deposit in Bolivia is characterized by low radiogenic element contents. Previously reported field evidence and mineral associations suggest the mineral formed via direct precipitation from hydrothermal fluids. Monazite compositions thus may provide insight into characteristics of the fluids from which it formed. Chemical compositions of three Lla...
We aimed to investigate the effect of chronic radiation exposure associated with the Fukushima Daiichi Nuclear Power Plant (FNPP) accident on the testes of boar and inobuta (a hybrid of Sus scrofa and Sus scrofa domestica). This study examined the contamination levels of radioactive caesium (Cs), especially (134)Cs and (137)Cs, in the testis of both boar and inobuta during 2012, after the Fukus...
AIM To develop methods of articular cartilage preparation for X-ray-electron probe microanalysis and to study its elements content in experimental osteoarthrosis. METHODS Twenty dogs aged 2-8 years were divided in research (aged 2 years, induction of osteoarthrosis - IOA) and intact group. Intact group included three subgroups (aged 2, 5 and 8 years). Samples of cartilage after araldite satur...
The influences of minor Cu addition (2 and 4 at.%) on the microstructural evolution room-temperature mechanical property metastable Co35Cr25Fe30Ni10 are systemically investigated in present study. results indicate that thermally induced hexagonal close-packed (HCP) phase is absent when was added, due to increase stacking fault energy (SFE). 2%-Cu-added alloys showed largest total elongation 69%...
Modern blast furnaces with extensive operational volume demand better-quality iron agglomerates as feed for stable operation. Sinter is the principal used in across Asia. Liquid generated during sintering process plays an essential role coalescence of sinter blend and quality. Therefore, estimation liquid properties at peak bed conditions helps manage behaviour, leading to better control final ...
We report a simple method to study the elemental content in cultured human adherent cells by electron probe X-ray microanalysis with scanning electron microscopy. Cells were adapted to grow on polycarbonate tissue culture cell inserts, washed with distilled water, plunge-frozen with liquid nitrogen and freeze-dried. Unstained, freeze-dried cultured cells were visualized in the secondary and bac...
