به منظور شناسایی فون نماتودهای خاکهای زراعی منطقه جیرفت و کهنوج در استان کرمان، طی سال های 1382 و 1383، تعداد 250 نمونه خاک و ریشه از گیاهان زراعی منطقه جمع آوری و نماتودهای موجود در آنها با استفاده از روش الک ها و سانتریفوژ استخراج گردید. نماتودهای استخراج شده با استفاده از روش دگریسه (de grisse, 1969) به گلیسیرین منتقل و پس از تهیه اسلایدهای دائمی با استفاده از میکروسکوپ نوری شناسایی شد. در ...
Although one of the ultimate goals of ecotoxicology is to predict the effects of chemical substances and compounds on whole communities and ecosystems, it is generally accepted by ecotoxicologists that single-species toxicity tests may provide an adequate first step toward the ecological risk assessment of pollutants in soil and water. Consequently, several toxicity tests (ASTM 1993) have been ...
Aβ (amyloid β-peptide) has a central role in AD (Alzheimer's disease) where neuronal toxicity is linked to its extracellular and intracellular accumulation as oligomeric species. Searching for molecules that attenuate Aβ aggregation could uncover novel therapies for AD, but most studies in mammalian cells have inferred aggregation indirectly by assessing levels of secreted Aβ peptide. In the pr...
Intrinsically disordered proteins (IDPs) lack well-defined structure but are widely represented in eukaryotic proteomes. Although the functions of most IDPs are not understood, some have been shown to have molecular recognition and/or regulatory roles where their disordered nature might be advantageous. Anhydrin is an uncharacterized IDP induced by dehydration in an anhydrobiotic nematode, Aphe...
the present study attempts to discover ideological differences between alcott’s novel (1868) named “little women” and its two persian translations. the first has been translated by morvarid and the second has been translated by obeidi. to this end, farahzad’s cda approach (2012) was used to analyze the ideology reflected in both translations by the two different translators. according to farahz...
according to webster and wind (1972) and anderson et al (1987), “organizational buying is a complex process and involves many people from different functional areas, multiple goals and potentially conflicting decision criteria. moreover, the customers of today are also more knowledgeable and selective when making their purchasing decisions. since a key to organizational survival is the retentio...
the aim of this study is investigating the effect of teaching “metacognitive strategies” on the way which scientific information retrieval workes by the using of google scholar searching machine on the students of ms in the psycology & education faculty of allameh tabatabayi university in 2007-2008 academic year. the statistical community was the students of ms in psychology & education facult...
The bacterium Acidovorax avenae causes disease in a wide range of economically important monocotyledonous and dicotyledonous plants, including corn, rice, watermelon, anthurium, and orchids. Genotypic and phenotypic relatedness among strains of phytopathogenic A. avenae subsp. avenae, A. avenae subsp. citrulli, A. avenae subsp. cattleyae and A. konjaci, as well as all other Acidovorax species, ...
LEA (late embryogenesis abundant) proteins in both plants and animals are associated with tolerance to water stress resulting from desiccation and cold shock. However, although various functions of LEA proteins have been proposed, their precise role has not been defined. Recent bioinformatics studies suggest that LEA proteins might behave as molecular chaperones, and the current study was under...
