introduction natural and artificial radionuclides are the main sources of human radiation exposure. these radionuclides, which are present in the environment, can enter the food chain. rice is one of the most important food components in iran. radionuclides by transferring from soil to rice and entering the human body can affect human health. materials and methods fourteen samples of different ...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Introduction Natural and artificial radionuclides are the main sources of human radiation exposure. These radionuclides, which are present in the environment, can enter the food chain. Rice is one of the most important food components in Iran. Radionuclides by transferring from soil to rice and entering the human body can affect human health. Materials and Methods Fourteen samples of different ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
: heavy metals are chemical pollutants characterized by their toxicity, stability, bioaccumulation and biomagnification. they might accumulate in aquatic organisms, transfer through food chain and enter into human body. therefore, the study of their accumulation in the edible aquatic species has been a very important part of ecological and monitoring investigations. astacus leptodactylus is a b...
august wilson is undoubtedly one of the rare black playwrights whose works have attracted streams of attention and worldwide audience. the present study aims at analyzing fences and piano lesson which are two of the most successful plays in his pittsburgh cycle from the perspective of michel foucault’s theories and ideas. studying these two plays from foucault’s perspective opens new windows in...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
Heavy metal metals are non-biodegradable, have a remarkable ability to transfer through food chains and are potentially toxic for organisms.They are introduced tomarine environment via different anthropogenic sources. In this study, the ability of titanium dioxide nano-particle in transfer of Cr, Cu, Pb and Se metal through an aquatic food chain involving Ceratium tripos as the phytoplankton Da...
introduction natural and artificial radionuclides are the main sources of human radiation exposure, which enter the food chain from the environment. radionuclides can affect human health by transferring from soil to plants and entering the human body. in this research study, we aimed to determine the activity concentrations of radionuclides and calculate the average annual committed effective d...
this thesis examines the significances and implications of inflicted physical pain in waiting for the barbarians (1980) by john maxwell coetzee (1940 - ). the researcher tries to show how body becomes a site for exercising violence. in this way, the government’s representatives turn bodies of the barbarians into blank pages through torturing in order to create the truth of the empire. in this p...
