The system of stochastic differential equations describing a nonautonomous density-dependent predator-prey model with Holling-type II functional response disturbed by white noise, centered and non-centered Poisson noises is considered. So, in this we take into account levels predator density dependence jumps, corresponding to the measures. existence uniqueness theorem for positive, global (no e...

Risks are natural and inherent characteristics of major projects. Risks are usually considered independently in analysis of risk responses. However, most risks are dependent on each other and dependent risks are rare in the real world. This paper proposes a model for proper risk response selection from the responses portfolio with the purpose of optimization of defined criteria for projects. Th...

inulin is widely used in functional foods throughout the world for its health-promoting and technological properties. helianthus tuberosus is cultivated widely in the northern part of iran. helianthus tuberosus can be a valuable source of inulin. to optimize conventional extraction of inulin, various combinations of time, temperature, and solvent: solid ratio, were used. in this research, a ser...

cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. in this study, the effect of chronic administration of sesame (sesamum indicum l) seed feeding was studied on aortic reactivity of streptozotocin (stz)-diabetic rats. male diabetic rats received sesame seed-mixed food at weight ratios of 3% and 6% for 7 weeks, one week after diabetes in...
