to investigate uterine fluid and serum copper (cu) and zinc (zn) variations during the estrous cycle in water buffaloes, 71 genital tracts and blood samples were collected from the abattoir in urmia, iran. the phase of the estrous cycle was determined by examining ovarian structures; 18, 15, 16 and 22 were pro-estrous, estrous, met-estrous and diestrous, respectively. the uterine fluid was coll...

for a given graph $g=(v,e)$, let $mathscr l(g)={l(v) : vin v}$ be a prescribed list assignment. $g$ is $mathscr l$-$l(2,1)$-colorable if there exists a vertex labeling $f$ of $g$ such that $f(v)in l(v)$ for all $v in v$; $|f(u)-f(v)|geq 2$ if $d_g(u,v) = 1$; and $|f(u)-f(v)|geq 1$ if $d_g(u,v)=2$. if $g$ is $mathscr l$-$l(2,1)$-colorable for every list assignment $mathscr l$ with $|l(v)|geq k$ ...

in this paper we define the removable cycle that, if $im$ is a class of graphs, $gin im$, the cycle $c$ in $g$ is called removable if $g-e(c)in im$. the removable cycles in eulerian graphs have been studied. we characterize eulerian graphs which contain two edge-disjoint removable cycles, and the necessary and sufficient conditions for eulerian graph to have removable cycles h...

water sources optimizing required a suitable irrigation program. different material can use to increase water use efficiency. superabsorbent is one of the materials where used in around the world. these materials put in the soil and absorb water so that reserved water is usable by plant in the time of drought stress and they can reduce stress and lead to prevent yield loss. therefore, the exper...

In this research accumulative roll bonding process as sever plastic deformation process was applied up to 8 cycles to produce the ultrafine grain copper. Microstructure of cycle 1, cycle 4 and cycle 8 investigated by TEM images. By analyzing TEM images the grain size measured below 100 nm in cycle 8 and it was with an average grain size of 200 nm. Corrosion resistance of rolled copper stri...

cytotoxicity evaluation of daphne mucronata (thymelaeaceae) extract and one of its active purified components, using seven different cancerous cell lines, revealed the strong antiproliferative activity of the plant. using flow cytometry technique, it was found that treatment of the most responsive cells (k562) with the plant extract or the active component inhibited the progression of cells thr...

background: various uterine disorders lead to infertility in women of reproductive ages. this study was performed to describe common uterine causes of infertility and sonographic evaluation of them for midwives.   methods:to study the literatures, manuscripts published at “pubmed”, “elsevier”, “google scholar”, “sid” and original text books, between 1985 and 2015, were carefully reviewed, using...

to investigate the igg content and its variations in uterine fluid (uf) during the estrous cycle of the cow and to compare them with those of the blood serum (s), six pairs of serum and uf samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from urmia abattoir. the uf samples were collected by gentle scraping of the endometrium using a ...

introduction: effects of exercise on different body systems, especially cardiovascular and musculoskeletal systems are evidenced. there is a dynamic homeostatic balance between coagulation and fibrinolysis in normal circulation. effect of exercise and training on this homeostatic balance has been studied extensively but there are a few studies with regards to analysis of the effects of training...
