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.
Plasma cholecystokinin (CCK) levels in fed rats increased from 2.59 ± 0.13 pmol/l to the peak of 27.6 ± 4.1 pmol/l at 1 h after a single oral administration of synthetic protease inhibitor (PI; ethyl N-allyl- N-{( E)-2-methyl-3-[4-(4-amidino-phenoxycarbonyl)phenyl]propenoyl}amino acetate methansulfonate; 20 mg/kg body wt), but then returned to the preloading value at 12 h after administration. ...
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...
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.
OBJECTIVES: Regimens containing protease inhibitors (PI) are less commonly used in developing countries due to high cost and less availability. We evaluated characteristics of patients initiating PI-based therapy according to previous antiretroviral (ARV) exposure; factors associated with initiating a PI-containing regimen using newer versus older PIs, and proportion of patients with detectable...
Using data collected with the CLEO detector operating at the CESR e+e- collider at sqrt[s]=3.97-4.26 GeV, we investigate 15 charmonium decay modes of the psi(4040), psi(4160), and Y(4260) resonances. We confirm, at 11 sigma significance, the BABAR Y(4260)-->pi+pi- J/psi discovery, make the first observation of Y(4260)--> pi(0)pi(0) J/psi (5.1 sigma), and find the first evidence for Y(4260)-->K+...
in this paper, we present some inequalities for the co-pi index involving the some topological indices, the number of vertices and edges, and the maximum degree. after that, we give a result for trees. in addition, we give some inequalities for the largest eigenvalue of the co-pi matrix of g.
Structures are reported here for eight further substituted N-aryl-2-chloronicotinamides, 2-ClC(5)H(3)NCONHC(6)H(4)X-4'. When X = H, compound (I) (C(12)H(9)ClN(2)O), the molecules are linked into sheets by N-H...N, C-H...pi(pyridyl) and C-H...pi(arene) hydrogen bonds. For X = CH(3), compound (II) (C(13)H(11)ClN(2)O, triclinic P1 with Z' = 2), the molecules are linked into sheets by N-H...O, C-H....
INTRODUCTION Response to antiretroviral therapy (ART) among individuals infected with HIV-2 is poorly described. We compared the immunological response among patients treated with three nucleoside reverse-transcriptase inhibitors (NRTIs) to boosted protease inhibitor (PI) and unboosted PI-based regimens in West Africa. METHODS This prospective cohort study enrolled treatment-naïve HIV-2-infec...
