In order  to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in Isfahan. The experiment was conducted as split plots in a randomized complete blocks design with three replications in Isfahan (51° 48' E, 32° 40' N).Main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class A and cultiv...

We investigate the model checking problem for a class of petri nets using net unfoldings. Net unfoldings are a well studied partial order semantics for petri nets and are well-suited for modeling concurrent and distributed systems. We consider the problem of model checking LTL-X (LTL without the next time operator) with fairness assumptions for the class of one-safe petri nets. Recently, in [1]...

Oxidative stress mediates cell injury during ischaemia/reperfusion. On the other hand, experimental findings suggest that ROS (reactive oxygen species) induce processes leading to ischaemic preconditioning. The extent and source of oxidative stress and its effect on antioxidant status in the human liver during intermittent ischaemia and reperfusion remains ill-defined. Therefore the aim of the ...

The net effective temperature (NET), an index that includes the combined effects of temperature, humidity, and wind, was used along with to assess impacts climate change on heat-stress perception in East Asia, one regions considered most vulnerable heat stress. need for dynamic downscaling has been emphasized because regional do not follow global levels linearly. In this study, daily maximums c...

The paper determined optimum farm plan for food security among smallholder farmers in Imo State, Nigeria. Data were collected with structured and validated questionnaire from 180 smallholder crops farmers in Imo State. Data were analyzed using descriptive statistics (mean, frequency distribution and percentages), budgetary analysis and linear programming model. Results show that the mean age of...

BACKGROUND The aim of the present randomized controlled trial was to compare the outcome of 2 active treatments for posttraumatic stress disorder (PTSD) as a consequence of war and torture: narrative exposure therapy (NET) and stress inoculation training (SIT). METHODS Twenty-eight PTSD patients who had experienced war and torture, most of them asylum seekers, received 10 treatment sessions o...

in order to evaluate drought tolerance of chickpea genotypes and identifying the best indices of drought tolerance, the 20 genotypes desi chickpea plus two improved cultivars (kaka and piroz) were tested using a randomized complete block design under two irrigated (non stress) and (stress) conditions. quantitive drought tolerance and susceptibility indices such as stress tolerance index (sti), ...

Monthly evapotranspiration (ET) rates (2000 to 2009) across Nebraska at about 1-km resolution were obtained by linear transformations of the MODIS (MODerate resolution Imaging Spectroradiometer) daytime surface temperature values with the help of the Priestley-Taylor equation and the complementary relationship of evaporation. For positive values of the mean annual precipitation and ET differenc...

The objective of the study is to compute various reliability parameters for multi-robotic system, using Real Coded Genetic Algorithms (RCGAs) and Fuzzy Lambda-Tau Methodology (FLTM). The paper contains a new idea about the reliability analysis of robotic system. The optimal values of mean time between failures (MTBF) and mean time to repair (MTTR) are obtained using GAs. Petri Net (PN) tool is ...
