The study is aimed at the investigation of the effects of GnRH agonist (alarelin) immunization on the vaginal electrical resistance (VER) and secretion of FSH and LH in sheep. Forty-two prepubertal female sheep were assigned to six groups (n = 7). Animals in experimental groups I (EG-I), II (EG-II), and III (EG-III) were twice subcutaneously injected with 200, 300, and 400 μg of alarelin antige...

Energy concentration of gain (EG) is an inherent component in beef cattle feeding systems. The National Research Council (NRC) uses equations based on body weight, rate of gain and cattle type to predict EG and, in turn, to calculate dietary energy requirements. From EG, fat and protein deposition can be calculated directly. A dynamic computer growth model also can be used to estimate EG. In bo...

fluids for various industrial applications because of their excellent thermal performance. this study analytically and experimentally examines the effects of nanoparticle dispersion on the entropy generation of eg–al2o3 nanofluid flows through a helical pipe as a heat exchanger under constant wall heat flux thermal boundary condition in laminar regime. it is found that adding nanoparticles impr...

Due to emergence of serious obstacles by scaling of the transistors dimensions, it has been obviously proved that silicon technology should be replaced by a new one having a high ability to overcome the barriers of scaling to nanometer regime. Among various candidates, carbon nanotube (CNT) field effect transistors are introduced as the most promising devices for substituting the silicon-based ...

We consider extremal graph-theoretic problems on regular structures. The problems ask to maximize a certain parameter of the structures in question under the condition that the values of some other parameter(s) are constant. This is where the term isoparametric is taken from. The graph problems we consider are edge-isoperimetric problems, and the poset problems are dealing with the notion of Ma...

Let $R$ be a commutative ring with nonzero identity and let $M$ unitary $R$-module. The essential graph of $M$, denoted by $EG(M)$ is simple undirected whose vertex set $Z(M)\setminus {\rm Ann}_R(M)$ two distinct vertices $x$ $y$ are adjacent if only ${\rm Ann}_{M}(xy)$ an submodule $M$. $r({\rm Ann}_R(M))\not={\rm Ann}_R(M)$. It shown that connected diam}(EG(M))\leq 2$. Whenever Noetherian, it...

The aim of this study was to investigate the effects of a 12-week rehabilitation program on body composition, shoulder pain, and isokinetic internal/external torques of pitchers with impingement syndrome. A total of 30 pitchers were divided into 2 groups: experimental group (EG, n = 16) and control group (CG, n= 14). The rehabilitation program consisted of physical therapy, warm-up, work-out, a...

Embryonic germ (EG) cells derived from primordial germ cells are undifferentiated and pluripotent stem cells. In our study, primordial germ cells isolated from the genital ridges of Beijing duck (Anas domestica) embryo at stage 28 were co-cultured with mice embryonic fibroblasts. Duck EG cells grew with a high nuclear:cytoplasm ratio and were positive for periodic acid-Schiff and alkaline phosp...
