Circular programming problems are a new class of convex optimization problems that include second-order cone programming problems as a special case. Alizadeh and Goldfarb [Math. Program. Ser. A 95 (2003) 3-51] introduced primal-dual path-following algorithms for solving second-order cone programming problems. In this paper, we generalize their work by using the machinery of Euclidean Jordan alg...

abstract ischemic brain edema is one of the most important complications of a stroke. this study aims to investigate the impact of pre-feeding of flax seed oil on blood-brain barrier in rat stroke model. in this experimental study animals were randomly divided into 3 groups of experiment, sham, and control. each testing group itself was consisted of 3 subgroups receiving doses of flaxseed oil w...

Reproduction of a mammalian organism involves inherited genetic programming and environmental factors that collectively shape organ development and function in the new offspring. One such factor are the indigenous microbiota and their interactions with the host. In mammals, the placenta ensures the supply of nutrition and oxygen to the fetus in utero. Microbes are thought to contribute to estab...

Under commercial conditions, weaning of piglets is associated with social, environmental and dietary stress. Consequently, small-intestinal barrier and absorptive functions deteriorate within a short time after weaning. Most studies that have assessed small-intestinal permeability in pigs after weaning used either Ussing chambers or orally administered marker probes. Paracellular barrier functi...

The aim of the present study was to determine the relationship between the dimensions of glass ceiling and the organizational commitment of women employees at University of Isfahan, which was conducted by a correlational-type descriptive method. The study population consisted of the women employees working at University of Isfahan, whose number stood at 428 individual and 202 individuals of the...

Nanoscale Schottky barrier MOSFETs (SBFETs) are explored by solving the two-dimensional Poisson equation self-consistently with a quantum transport equation. The results show that for SBFETs with positive, effective metal-semiconductor barrier heights, the on-current is limited by tunneling through a barrier at the source. If, however, a negative metal-semiconductor barrier height could be achi...

the prevention of bbb breakdown and the subsequent vasogenic edema are important parts of the medical management of ischemic stroke. the purpose of this study was to investigate the ischemic tolerance effect of rosmarinus officinalis leaf hydro-alcoholic extract (rhe).five groups of animals were designed: sham (underwent surgery without mcao) and mcao groups, the mcao groups were pretreated ora...

noncatalytic and nonoxidative conversion of methane in a dielectric barrier discharge (dbd) reactor is examined at different temperatures, gas residence times and input powers. in addition, the ratio of methane to helium as a diluant, is changed in the range of 0.6 to 1.8. results show significant synergetic effects of plasma, temperature and helium on the methane conversion and c2+ selectiviti...

in this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. in this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...

nowadays, the application of information technology is associated with barriers and challenges. so to prioritize barriers to information technology application in sports organizations, the viewpoints of 71 experts and managers of these organizations were collected by answering a researcher-made questionnaire. validity (face, content) of this questionnaire was confirmed by experts and its reliab...
