section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
the present study was undertaken to investigate the role of banana extract (be) on synchronous plantlet formation from seeds of dendrobium lituiflorum lindl. the seedlings formed on modified knudson c (kc) medium supplemented with 20% (v/v) be had significantly high fresh and dry weights. morphologically uniform plantlets with elongated leaves and well developed roots were formed on kc medium w...
Objective(s): The effect of prolonged overtraining on cytokine kinetics was compared with moderate exercise in the present study. Materials and Methods: Male Wistar rats were randomly divided into control sedentary (C), moderate trained (MT), (V=20 m/min, 30 min/day for 6 days a week, 8 weeks), overtrained (OT) (V=25 m/min, 60min/day for 6 days a week, 11 weeks) and recovered overtrai...
language learning courseware has been receiving growing attention by english educators since its advent. a variety of softwares have been designed by software designers and resorted to by language educators to supplement language textbooks. this experimental study investigated how the application of computerized version of language textbooks and the reception of the entire course through comput...
The electrocatalysis of the oxygen reduction reaction (ORR) on carbon supportedPt-V (1:1) catalyst in polymer electrolyte fuel cells (PEFC) was investigated. Atan oxygen pressure of one atm an enhanced electrocatalytic property of Pt-V/Ccompared with Pt/C is revealed. These results indicate the occurrence of adifferent electrocatalytic mechanism for the ORR on Pt/C and Pt-V/C. Anincrease of mas...

در این مقاله نظریه ی kبرای c^*- جبر c^*(v,f) مربوط به به c^?- برگ بندی های(v,f) در ساده ترین حالت نا بدیهی یعنی بعد دو مطالعه می شود.چون حالت برگ بندی کرونکر توسط پیمسر و ویکو لسکو بررسی شد، مساله ی باقی مانده مربوط به برگ بندی ریب می باشد. د ر این حالت c^*- جبر ساده ی k_*c^*(v,f) با استفاده از دنباله ی مایر ویتوریس و دنباله ی دقیق شش عبارتی محاسبه می شود. نتایج بدست آمده c^*- جبر برگ بندی ریب...
background: severe preeclampsia is a quite well-known entity with high incidence of both maternal and fetal morbidity and mortality. although little is known about its etiology, inherited disorders of hemostasis and antiphospholipid syndrome have been postulated as common causes. the present study was conducted to evaluate the association of these two entities with preeclampsia in a group of ir...
