در این پژوهش بعد از معرفی تحقیقات انجام یافته بر روی فرزکاری سطوح سه بعدی با استفاده از ابزارهای مختلف ، روش (principal axis method)pam به عنوان یک روش کارا در تولید سطوحی با صافی سطح یکنواخت وبالا که در ماشینهای 5 محوره به خوبی قابل اجراست معرفی شده و در نهایت صافی سطح به وجود آمده در فرزکاری با روش pam و ابزار توروئیدی (toroidal endmill) با دو ابزار دیگر ، سرگرد(ball nose endmill) ، و سرسخت (...
the objective of this study was to investigate the relationship among body weight and fat-tail measurements with fat-tail weight by using multiple regression and principal component analysis. the eleven characters includes, body weight, fat-tail length, fat-tail circumference, width and diameters in 3 position of upper, middle and lower before the slaughter, and also fat-tail weight after the s...
Introduction: Barrel cortex of rodents is responsible for sensory information processing from muzzle whiskers. Locus coeruleus (LC) as the main source of norepinephrine (NE) in the cortex, is effective on the sensory information processing. Methods: Rats were divided to 2 groups. One group underwent sensory deprivation (P4) and the other group served as control and did not undergo sensory d...
background: cutaneous leishmaniasis is one of the most important parasitic diseases in humans. in this disease, one of the responsible organisms is leishmania major, which is transmitted by sandfly vector. there are specific differences in biochemical profiles and metabolite pathways in logarithmic and stationary phases of leishmania parasites. in the present study, 1h nmr spectroscopy was used...
in this paper we investigate generalized topologies generated by a subbase ofpreorder relators and consider its application in the concept of the complement. we introducethe notion of principal generalized topologies obtained from the new type of open sets andstudy some of their important properties.
