Umbelliprenin is a prenylated compound, which belongs to the class of sesquiterpene coumarins. It is extracted from dried roots of Ferula szwitsiana collected from the mountains of Golestan forest (Golestan Province, north of Iran). Induction of apoptosis in Jurkat T-CLL cells has been previously shown. In this study, effect of umbelliprenin on proapoptotic caspases (caspase-8 and -9) and antia...
a simple, sensitive and selective method for solvent extraction and spectrophotemetric determination of lanthanum (ii) europium (iii), and cerium (iii) is described , the rare earth metals are extracted into chloroform solution of n-phenylbenzohydroxamic acid (pbha) at ph 9-10 various parameters are studied to optimize the extraction conditions. the molar absorptivity is found to increase from ...
Although delinquency is universal, few studies examined it from an Asian perspective, and even fewer considered adolescents of divorced families in Iran. The current study examined whether correlates of delinquency among western adolescents are similarly effective for predicting delinquency among adolescents from divorced families in the Mashhad city in Iran. Post-divorce parental conflict, mat...
many political concepts as well as technology exported to various regions of the world from europe after renaissance, industrial revolution and protestantism. meanwhile western technology andconcepts of political philosophy came to iran since nineteenth century. republicanism was one of these concepts. this concept and idea as one of the most factors in iranian contemporary political - social t...

abstract deviation or in other words committing a crime is literally a social problem. this research that was conducted in 1389 and 1390 has tried to investigate the causes of crimes committed by young male inmates qazvin central prison and effective variables on their tendency to deviation. accordingly after collecting theoretical framework and offering theoretical model including both hirsch...
Background: A microscopic study on ancient metals was established to identify chemical composition and microstructure of archaeological tin bronze objects. For this purpose, ten small bronze pieces from Baba Jilan Iron Age site, western Iran, were selected and studied by optical microscopy (OM) and scanning electron microscopy–energy dispersive X-ray spectroscopy (SEM–EDS) methods. Results: The...
Foucault is among few western thinkers who have closely witnessed Islamic revolution happening in Iran. His interviews and articles in this regard have been published. Despite his efforts to study how Islamic revolution was formed and triumphed, his viewpoints have been published in sporadic articles and interviews lacking an integrated theoretical model. Seven variables are identifiable in his...
This project is a fundamental study into the development of low-cost, thin film solar cells. It explores the fabrication of semiconductor nanocomposites for photovoltaics using nanostructured inorganic materials and atomic layer deposition (ALD). In thin film technologies, there exists a common problem with conversion efficiency due to poor materials quality: the photogenerated electrons and ho...
