Imaging the Recalescence Behavior of Undercooled Nickel
The thermal front accompanying recalescence of undercooled pure nickel melts was characterized using a high speed digital imaging technique. Nucleation was either spontaneous or was stimulated using a physical trigger to induce heterogeneous nucleation at a known site at the desired undercooling. Undercoolings ranged from 30 to 300 *C, with measured velocities between 0.3 and 50 rn/sec using a ...
متن کاملAntimony in Malaria
A few months ago we refused to publish in this journal an advertisement of an antimony preparation which was said to be a specific remedy for malaria in all forms. This preparation appeared to be an ordinary pentavalent one. In our present number we publish an article by P. C. Sen Gupta on malaria complicating kala-azar, in which it is recorded that malaria may occur during or immediately after...

OBJECTIVE To determine whether antimony may be detected in the urine during infancy and early childhood and its association with passive exposure to tobacco smoke, as assessed by urinary cotinine. DESIGN Analysis of spare aliquots of urine collected from infants participating in studies of respiratory function and passive smoking. Urinary antimony was assayed using inductively coupled plasma ...
متن کاملAntimony Toxicity
Antimony toxicity occurs either due to occupational exposure or during therapy. Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. In addition antimony trioxide is possibly carcinogenic to humans. Improvements in working conditions have remarkably decreased the incidence of antimony toxicity in the workplace. As a th...
متن کاملDisintegration of antimony-124.
The radiations from 60-day Sb lN have been studied by several investigators. H ales and Jordan [2] used a 1800 spectrometer to study the beta spectrum of Sb124. Tbey report the presence of two components with maximum cnergies at 0.74 ± O.03 and 2.45 ± 0.07 million electron volts (NIev) . ~1iller and Omtiss [3], u ing a thin magnetic len spectrometer , also ob erved a complex beta specLrum, but ...
