safflower is one of the oldest cultivated plants and oilseed as a native iran could have in the development of oilseeds cultivation. to evaluate the morphological characteristics of safflower (carthamus tinctorius l) an experiment was conducted as a completely randomized design. the figures include 1- pi 23755 2-pi 239041 3- pi 250202 4- pi 250532 5- pi 25268 6- pi 253515 7- pi 253541 8- pi 253...
in this paper some upper and lower bounds for the greatest eigenvalues of the pi and vertex pimatrices of a graph g are obtained. those graphs for which these bounds are best possible arecharacterized.
OBJECTIVES To compare the feasibility of two transabdominal approaches for performing first-trimester uterine artery (UtA) Doppler and to evaluate the correlation with pulsatility index (PI) in the second trimester. METHODS This was a prospective longitudinal Doppler study of the uterine arteries at 11-13 and 21-22 weeks' gestation. Transabdominal ultrasound and color Doppler were used to mea...
OBJECTIVE To evaluate the performance of screening for pre-eclampsia by uterine artery pulsatility index (PI) at 11 + 0 to 13 + 6 weeks' gestation and the change in uterine artery PI between 11 + 0 to 13 + 6 and 21 + 0 to 24 + 6 weeks. METHODS In 3107 singleton pregnancies attending for routine care at 11 + 0 to 13 + 6 and 21 + 0 to 24 + 6 weeks' gestation we recorded maternal characteristics...
In three experiments broiler chickens were inoculated with sporulated Eimeria acervulina oocysts at 18 d of age. Feed intake, body-weight gain, brush-border enzyme activities, fat digestion, protein digestion and protein retention were measured. Body-weight gain was reduced during the acute phase of the infection and increased during the recovery phase of the infection. Feed intake was decrease...
شاخص توپولوژیک عددی حقیقی است که به یک گراف نسبت داده می شود و تحت یک ریختی گراف ثابت می ماند. شاخص های توپولوژیک برای بررسی خواص فیزیکی-شیمیایی ترکیبات شیمیایی به کار می روند. شاخص pi در مقاله ای در سال 2009 در تلاش جهت یافتن رابطه ای دقیق برای محاسبه ی شاخص pi رأسی حاصل ضرب دکارتی گراف ها معرفی شد. بعدها کاربردهای فراوانی از این شاخص در علوم نانو و شیمی به دست آمد. مطالعه ی ریاضی ای...
Using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector at the CESR e;{+}e;{-} collider, we make the first observations of the decays eta;{'}-->pi;{+}pi;{-}pi;{0} and eta;{'}-->pi;{+}pi;{-}e;{+}e;{-}, measuring absolute branching fractions (37_{-9};{+11}+/-4)x10;{-4} and (25_{-9};{+12}+/-5)x10;{-4}, respectively. For eta;{'}-->pi;{+}pi;{-}pi;{0}, this re...
in this paper, at first we mention to some results related to pi and vertex co-pi indices and then we introduce the edge versions of co-pi indices. then, we obtain some properties about these new indices.
به منظور شناسایی لاین های حاوی ژن های مقاوم به بلاست pi-1، pi-2 و درجه مقاومت نسبی ارقام برنج نسبت به قارچ pyricularia griseasacc، جمعیت تلاقی برگشتی سوم ارقام طارم محلی و طارم دیلمانی مورد ارزیابی مولکولی و فنوتیپی قرار گرفتند. طرح تلاقی برگشتی به منظور انتقال ژن های غالب مقاوم به بلاست به ترتیب از لاین های ایزوژنc101lac و c101a51 به ارقام کیفی طارم دیلمانی و طارم محلی که حساس به بلاست هستند، ...
