in the recent years, sediments are used for the assessment of pollution. since sediments have been in contact for a long time with over lying water, therefore they have been able to adsorb pollution on to their surface. in the present investigation, the surficial sediments of siahrud river have been analyzed. the loose, sulphide and organic bonds of metals with various sedimentary phases has be...
Cytarabine is the drug of choice for treatment of leukemia. However, many formulations have been prepared, due to certain limitations they could not prove to be effective ones, therefore magnetic microspheres are formulated as they minimize the Reticuloendothelial clearance and target site specificity can be increased. The current study aimed to utilize nanotechnology to develop magnetic micros...
Introduction: In recent years, compact fluorescent lamps have been more widely used across the country as a means of optimizing energy consumption. Given the health consequences of lighting sources, the present study was conducted to investigate the intensity of electromagnetic fields emitted by common compact fluorescent lamps. Materials and Methods: The study examined 54 compact fluo...
Introduction: Iron oxide nanoparticles, owing to their very small size and superparamagnetic properties, have been considered a potential candidate for several medical applications such as magnetic cell separation, magnetic resonance imaging (MRI), magnetic targeted drug delivery magnetichyperthermia. The present study aimed to synthesize and evaluate the characteristics of super...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
in this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. we have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. the spin-polarization parameter corresponding to the equilibrium state of ...
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
