kutum, rutilus frisii kutum, is an commercially important fish in the caspian sea. the fish enters the rivers leading to the caspian sea for spawning. one of these rivers is shiroud river. in the artificial propagation process of kutum, different factors are involved in quality and quantity of female broods eggs and also in the best temperature and migration time for spawning. the influence of ...

In the context of virtual machines live migration, two strategies called “pre-copy” and “post-copy” have already been presented; but each of these strategies works well only in some circumstances. In this paper, we have a brief presentation of QAVNS and then introduce a new approach which is based on the concept of "informational object", assigning QAVNS-scheme-revision number, and observing th...

Climate displaced persons generally follow the same trails as other migrants, but climate-induced displacement is adding to the pace and scale of human mobility. The prime aim of the study was to investigate the rural to urban migration of climate induced displacement in coastal area of Bangladesh addressing to risks and opportunities. The study mainly based on primary data and secondary data w...

The Image reconstruction is an important problem in optical tomography. The process of the image processing requires the study of photon migration in biological tissue. There are several approaches to study and simulate propagation of photons in biological tissues. These approaches are categorized into stochastic and analytical groups. The Monte Carlo method as a stochastic method is widely use...

background : angiogenesis, the formation of new blood vessels from preexisting ones, is among the most important physiological and pathological processes that occur in the body. under pathological conditions such as tumor growth, psoriasis, corneal neovascularization and rheumatoid arthritis, angiogenesis is substantial for the development of the disease. zataria multiflora is a member of the l...

the aim of this paper is to investigate the role of producer cooperatives (pcs) on rural development in fars, khorasan, semnan, golestan and hamadan provinces of iran in 2007. more specifically, this paper focuses on the economic aspects and social changes occurred in rural area concerning the cooperatives development. in order to measure quantitatively the effectiveness of economic and social ...

Objective(s):Degradation of sphingosine 1-phosphate (S1P), as a bioactive lipid, or deregulation of its production involves in tumor progression, metastasis and chemoresistance. Since the tumor progression effects of S1P and its mechanism in chronic lymphoblastic leukemia and non-small cell lung cancer is not fully understood, we investigated the role and one of the mechanisms of S1P in tumor p...

spinal cord injury (sci) results in the damage of motor and sensory pathways. the molecular and cellular structure of the injury milieu has been shown to be vital for endogenous regeneration in most tissues. regeneration of injured central nervous system (cns) is limited by damaged cell environment. biomaterial scaffolds can reconstruct injured cns tissue following sci by promoting the migratio...

objective: hydrostatic pressure is crucial component of cell environment and fundamental physical quantity, also it is the main factor of both cell integrity and function. pressure variation disorder, beyond physiological limits, may lead to pathological states. in this study, we examined the effect of hydrostatic pressure on apoptosis induction, viability, morphology, adhesion potency to subst...
