introduction: in recent years, public universities have faced many socio-economic changes. on one hand, these universities are under the main influence of the independence resulted from article 49 of law of the fourth economic, social and cultural development plan of the islamic republic of iran, and on the other hand, they have undergone double pressure due to the alterations in the number of ...

to study molecular evolutionary characteristics and genetics of beet necrotic yellow vein virus (bnyvv) isolates population from iran, nucleotide sequences of p25 and coat protein (cp) were determined and the amino acids sequences thus deduced were analyzed using phylogenetic and population genetics methods. a survey of bnyvv in iran indicated the infection of 288 collected samples out of 392 s...

sperms are highly specialized cells for delivering dna from male to the ovum. incredibly, wide degree of diversity in sperm morphology in their basic structures i.e. head, middle piece and tail is found across species. differences in terms of overall size of the sperm, shape and number of sperm produced are also incredible. one of the key for this variations or diversity in sperm may be associa...

echocardiography is a non-invasive diagnostic technique which provides information on cardiac morphology, function, and hemodynamics. it is the most frequently used cardiovascular diagnostic test only after electrocardiography. in less than five decades, the evolution in this technique has made it the basic part of cardiovascular medicine. herein, the evolution of various forms of echocardiogra...

in this article, we apply two new fixed point theorems to investigate the existence of mild solutions for a nonlocal fractional cauchy problem with an integral initial condition in banach spaces.

groundwater is the most widely distributed resource of the earth and groundwater quality evolves rapidly as it passes through the subsurface pathways within the unsaturated zone. increasing urbanization and anthropogenic activities have added to the problem of deficient amount of good quality groundwater. the study area is an industrial hub for textile sector. textile production, particularly d...

semilinear stochastic evolution equations with multiplicative l'evy noise are considered‎. ‎the drift term is assumed to be monotone nonlinear and with linear growth‎. ‎unlike other similar works‎, ‎we do not impose coercivity conditions on coefficients‎. ‎we establish the continuous dependence of the mild solution with respect to initial conditions and also on coefficients. ‎as corollaries of ...

determining the optimal location of wells with the aid of an automated search algorithm is a significant and difficult step in the reservoir development process. it is a computationally intensive task due to the large number of simulation runs required. therefore,the key issue to such automatic optimization is development of algorithms that can find acceptable solutions with a minimum number of...
