in order to investigate of quality and quantity yield and growing degree day (gdd) of plantago ovata and p. psyllium related to water stress and density, two experiments were conducted at the agriculture research field, tehran university, karaj, in april 2005 and 2006. the experiments were designed in factorial experiments based in randomized completely block (rcb) with three replication in whi...

background: considerable evidence suggests that oxidative stress affects diabetes mellitus (dm) and contributes to its complications. vitamin d has been shown to possess antioxidant properties. the aim of this study was to determine the association between serum levels of calcifediol (25-oh-d), an indicator of vitamin d status, and lipid profiles with oxidative stress in patients with type 2 di...

A novel method for transferring thin, large-area polymer layers from a mould and its subsequent bonding to a destination substrate is presented here. Buoyancy is used for transfer via floatation to allow the release of internal stress in the polymer and to avoid induced strain. Additionally, floatation leads to wrinkle-free contact between the polymer layer and its destination substrate, an imp...

‎In this paper‎, ‎we have investigated the chaotic behavior of thermal convection in couple stress liquid saturated porous layer subject to gravity‎, ‎heated from below and cooled from above‎, ‎based on theory of dynamical system‎. ‎A low dimensional Lorenz‎- ‎like model is obtained by using Galerkin-truncation approximation‎. ‎We found that there is proportional relation between scaled couple ...

Exposure to stress throughout life can cumulatively influence later health, even among young adults. The negative effects of high cumulative stress exposure are well-known, and a shift from episodic to stimulus-response memory has been proposed to underlie forms of psychopathology that are related to high lifetime stress. At the other extreme, effects of very low stress exposure are mixed, with...

objective: in order to study genetic variation and effect of drought stress on grain yield and some morphological traits in chickpea, an experiment was conducted on 64 genotypes during 2013-2014 cropping season at deputy of kermanshah sararood dry land agricultural research institute, located on the western part of iran. methods: the experimental design was a randomized lattice design with tow ...

aim and background: previous studies suggest that mental stress may influence serum lipid levels. this study was conducted on adult population living in rural and urban areas in central iran to assess the correlation between stress levels and lipid profile disorders. methods and materials: data was extracted from final evaluation of isfahan healthy heart program (ihhp) in 2008. multistage clust...

in order to investigate deformation history preserved in the calcite twins in the hinterland of zagros, several samples have been collected from calcschists of the paleozoic sargaz complex in the faryab area, se iran. these samples are related to f1-recumbent folding and thrust shear zones. the twin width is about 1 and 3.8 µm (thin-twin regime); the twin strain amounts 5 and 10%; twin intensit...
