it is obvious that lead intake is of concern not for its beneficial/essential effects on metabolism, but rather for its toxic actions, which can be especially damaging to children. the objective of this study was to analyze the concentration of lead in milk of mothers during prolonged lactation. milk samples from 43 mothers were collected at 2 months postpartum. lead was analyzed using atomic a...
Viscosity is one of the important parameters in design and production of composite solid propellants. Propellants with low end of mix (EoM) viscosity and longer pot-life have suitable condition for casting process. Several factors control the rheology behavior of propellants. In some cases, it may be necessary to apply some additives in order to optimize the rheology of the formulation. In this...
in this project, 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid, was prepared by the reaction of trimellitic anhydride (tma) with 4,4?-methylenebis(3-chloro-2,6-diethylaniline) (mcdea). the novel poly(amide-imide) (pai) was synthesized from the reaction of 4,4?-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with mcdea under green condition using ...

A factorial pot experiment was conducted based on randomized complete blocks design in green house condition to investigate the effect of short-term salt stress on leaf photosynthesis and ion relations of two sugar beet cultivars (Madison and 7233-P29). Plants were exposed to 0, 50, 150, 250, and 350 mM salinity (NaCl and CaCl2 in 5:1 molar ratio) for 48 hours. Measurements were done on younges...
