Visible/Near-Infrared Spectra of Experimentally Shocked Plagioclase Feldspars
Introduction: Minerals subjected to high shock pressures exhibit structural changes with increasing pressure (e.g., fractures, deformations, formation of diaplectic glass, and complete melting [1-6]). Petrologic and thermal infrared spectroscopic studies have shown that diaplectic glass (maskelynite) formation in feldspars occurs between ~25-45 GPa, while significant melting occurs above ~45 GP...

Rouf, M. A. (Washington State University, Pullman). Spectrochemical analysis of inorganic elements in bacteria. J. Bacteriol. 88:1545-1549. 1964.-Quantitative spectrochemical analyses of inorganic elements in the vegetative cells of Escherichia coli, Sphaerotilus natans, Micrococcus roseus, Bacillus cereus, and the spores of B. cereus were made. The following elements were found to be present i...
متن کاملDetermination and Application of Trace Elements
It is a well known fact that minera l plays an important role in the nutrition of animal and plant. The t race elements, which are a part of the mineral and exi st in a very small amount in the living bodies, include not only essential elements but also harmfu l and useless elements. In the researches up until now, physiological significance or essentiality for living body of such elements as c...

chronic hepatitis b virus (hbv) infection is a major liver disease worldwide and its clinical manifestations are linked to immune response. the purpose of this study was to evaluate the relationship between selenium, copper, and zinc in comparison with transaminase level in chronic hbv patients. serum samples of the hbv infected patients were obtained from tooba medical center, sari, iran. sixt...
متن کاملTrace Elements in High-ca Pyroxene & Plagioclase in the Bilanga Diogenite: Implications for the Magmatic Evolution of Diogenites
Introduction: High-Ca pyroxene and plagioclase are typically present as minor phases in diogenites [1]. However, although the trace element content of diogenite orthopyroxene has been measured in a number of studies e.g., [2, 3]; almost no trace element data is available for the high-Ca pyroxene and plagioclase with which it routinely coexists in these meteorites. These data could provide insig...
