chemical pollutants presence in water may induce severe ecological consequences and consequently affecting aquatic ecosystems integrity. heavy metals are dangerous pollutants for aquatic inhabitants that have a great stability. heavy metals contamination (pollution) of the surface waters happens widely by discharge of mill effluents. the objective of the present study was to determine the 50% l...
abstract heavy metals are the important pollution which there is in the aquatic ecosystems. today, with advances in technology have increased the pollution therefore it is important to assessment the risks. the aim of this study was acute toxicity effects of mercury chloride, lead chloride and zinc chloride in silver carp fish. in this study there were 5 treatments for lead chloride and mercury...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
background: since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. the aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of mercuric chloride (hgcl2), lead chloride (pbcl2) and zinc sulfate (znso4) pollutan...
abstract foreign and iranian cultures are far distinct in the constraints imposed on writing and translating for children, since the iranian literary system is mainly concerned with cultural and religious instructions which lead to manipulation of translated texts. this study sought to identify the cultural and social constraints and norms which determined the strategies applied in the transl...
