Its mineralogical composition also varies based on the cooling procedure. Two different types of steel slag were used as absorbing bed for various concentrations of Pb2+ ions in the form of lead chlor...
متن کاملThe absorption and retention of nitrogen from leaf protein by infants recovering from malnutrition.
In underdeveloped countries no source of protein can be neglected that is likely to be useful as human food. Duckworth and his colleagues have shown that leaf protein (LP) prepared by the method of Morrison & Pirie (1961) has good nutritive value for chicks, rats and pigs (Duckworth & Woodham, 1961; Duckworth, Hepburn & Woodham, 1961). These results were encouraging enough to justify trials on ...
متن کاملIon Absorption and Retention by Chlorella pyrenoidosa
MIost of the plant ion absorption experiments in the past have been condlucted with coenocytic algae and higher plants (24). In mature cells of these organisms the vacuole occupies 80 to 90 % of the cell volume. With respect to ionic movements the cytoplasm and vacuole represent 2 distinct physical compartments (2,16). As a result, the molecular details associated with ion absorption, as well a...

15 صفحه اولMONITORING OF LEAD POISONING IN SIMPLE WORKERS OF A COPYING CENTER BY FLAME ATOMIC ABSORPTION SPECTROSCOPY
Inorganic lead compounds are used most widely in paint and pigment industries. Because of exposure to lead dust in workers in a copying center, we compared blood lead levels in these workers to normal individuals and investigated the relationship between job tenures of the workers and their blood lead levels. This survey was performed on 20 simple workers in a copying center of Tehran Univ...
