A model is presented that describes the pumping characteristics of St707 getter material, the evaporation rate of antimony, and the resulting partial pressure of Sb within a vacuum chamber. The results show that within the 250-450◦C range, the partial pressure of antimony ranges from 10−7 Pa to 10−2 Pa. In a limiting case where the getter efficiency is tuned to 10, 000 L/s, partial pressures ar...

a highly selective, sensitive, rapid and economical differential pulse polarographic method has been developed for the determination of trace amounts of antimony in various standard alloys and biological samples after adsorption of its 2-nitroso-1-naphthol-4-sulfonic acid - tetradecyldimethylbenzylammonium chloride on microcrystalline naphthalene in the ph range of 7.5-11.0. after filtration, t...

introduction: the lymphatic system provides one of the main paths for the spread (metastasis) of cancer from one part of body to another. hodgkin’s diseases, lymphocytic leukemia, various metastatic disease and many lymph node disorders can be assessed by lymphoscintigraphy. radionuclide lymphoscintigraphy has been used for many years to define lymphatic drainage of melanoma. the most common ra...

then again there is the Bravo case, and those of Cook, llcMullan and Winslow, and lastly, the more'recent cases of Palmer and Klosowski. Poisoning by salts of antimony has occasionally been recorded in India, but it is usually spoken of as a rare occurrence in this country Is this really the fact, and lias arsenic such an absolute monopoly for criminal purposes as is generally believed ? Althou...

The effect of gold trichloride on DNA synthesis of human thymocytes and peripheral blood lymphocytes was tested. A stimulation was obtained in both cell types with a concentration of 6–50 μg/ml. Gold trichloride may thus not be used in a lymphocyte transformation test for the diagnosis of contact allergy.

It is suggested that the story of The Magic Flute owes much to alchemy and related early mineralogy; the operaÕs architectonic structure, including its musical structure, owes much to numerology. The plot is in large part an allegorical account or description of the alchemical process and the production of the PhilosophersÕ Stone from the prima materia stibnite (spiessglanz) (antimony trisulphi...

It has been shown previously that antimony evaporated onto a Au(111) surface grows in a layer-bylayer mode. The present work compares the initial, fast-oxidation stage of these films with that on bulk polycrystalline antimony. Measurements were carried out in an ultrahigh-vacuum environment using Auger electron spectroscopy, low-energy electron diffraction, electron-energy-loss spectroscopy, an...
