a total of 3528 specimens of freshwater turtles belonging to two families viz., geoemydidae (brown river turtle, kachuga smithi; indian saw-backed turtle, k. tecta; brahminy rrive turtle, hardella thurgi; spotted pond turtle, geoclemys hamiltonii) and trionychidae (indian soft-shell turtle, aspederates gangeticus; peacock soft-shell turtle, a.hurum; narrow-headed soft-shell turtle, chitra indic...
in this study, the amount of nickel and vanadium elements in the soft tissues of rock oysters (saccostrea cuculata) and sea water from coastal areas of qeshm island, the biggest island of persian gulf located in the south of iran, were measured to evaluate the contamination of the aquatic environment and organisms. following the bioassay, weighing and chemical digestion of the samples, finally...
The dynamics of Mn, Fe, Zn, Cu and Cd in the shell and soft tissues of the American oyster, Crassostrea virginica, were observed in oysters exposed in situ to a metal-contaiminated environment from September, 1972 until August, 1973. Zn and Cu accumulated in soft tissues of exposed oysters reaching levels of 4100 rg Zn/gm and 450 rg Cu/gm compared to 1700 pg Zn/gm and 60 pg Cu/gm for controls (...
Background and Objectives: The present study was designed to determine total mercury concentrations in sediment and the soft tissues of two bivalve species, Saccostrea cucullata and Callista umbonella, in coastline of Bandar Abbas in 2011. Materials and Methods: Generally, 67 bivalves and 10 sediment samples were collected from two stations (terminal of Bandar Abbas and tourism park of Soro). W...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Pollutants are persistent in the environment, taint food chain, and harm people's health because of their toxicity. In this study, mangrove snails called Cerithidea obtusa (C. Obtusa) were gathered from Southwest Johor, Malaysia, amounts macro micro elements Ca, Fe, K, Mg, Na, As, Mn, Zn soft tissues, shells, related surface sediments analysed. The Neutron Activation Analysis (NAA) method was u...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
levels of the heavy metals copper (cu), zinc (zn), lead (pb), cadmium (cd), chromium (cr), nickel (ni), iron (fe) and manganese (mn) were determined by graphite furnace atomic absorption spectrophotometer (model 67og) in coastal water, sediments and soft tissues of the saccostrea cucullata, from the intertidal zone at five stations in the gulf of chabahar on the iranian coasts along the oman se...
