the main objective of this study was to evaluate the effect of dietary inclusion of wheat or corn as the main source of starch in prepartum diets on colostrum composition, colostrum igg1 and igg2 concentrations, serum igg1 and igg2 concentrations of calves and efficiency of igg1, igg2 and total ig absorption. for this purpose, thirty primiparous and twenty multiparous holstein cows were used in...

it has been proved that sphericity testing for digraphs is an np-complete problem. here, we investigate sphericity of 3-connected single source digraphs. we provide a new combinatorial characterization of sphericity and give a linear time algorithm for sphericity testing. our algorithm tests whether a 3-connected single source digraph with $n$ vertices is spherical in $o(n)$ time.

a 50-year-old lady presented with bloody vomiting and melena since four days prior to admission. her medical history was significant only for hypertension which was controlled by a 5 mg daily dose of amlodipine. she occasionally took nsaids. on admission, the physical exam revealed only mild tachycardia and pallor. hemoglobin was 9.7 g/dl, which subsequently declined to 7.9 g/dl. the first uppe...

background: miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. the most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. in this research, we have surveyed and designed an am-be miniature neutron source fabrication. materials and methods: this investigation resulted in creation...
