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 ...
Background: Burn injuries are significant cause of mortality, morbidity and disability around the world. Occupational burns account for 10-45 percent of all burn injuries which cause burden of disease to the community. The incidence of occupational burns in Iran is higher than in developed countries. This study aimed to evaluate the epidemiology of occupational burns and its effect on...
چکیده رقابت پذیری معیاری کلیدی برای ارزیابی درجه موفقیت کشورها،صنایع و بنگاهها در میدان های رقابتی سیاسی،اقتصادی و نجاری به حساب می آید.بدین معنی که هر کشور،صنعت یا بنگاهی که از توان رقابتی بالایی در بازارهای رقابتی برخوردار باشد،می توان گفت که از رقابت پذیری بالاتری برخوردار می باشد.در تحقیقات مختلف، رقابت پذیری در سه سطح ملی،صنعت و بنگاه مورد توجه قرار گرفته که در این میان سطح بنگاه از د...
Glutamic Acid Decarboxylase(GAD) catalyses the conversion of glutamic acid to Gama amino Butyric Acid(GABA) which is one of the major inhibitory neurotransmitters in central nervous system. GAD has two isoforms with molecular weights of 65 Kda(GAD 65) and 67 Kda (GAD 67). GAD 65 gene is located on chromosome 10 and expressed in β-cells of pancrease. The presence of high concentrations o...
whitening as one of the stages in rice processing is performed following dehusking. studies on performance of milling machines prevailent in mazandaran province, as the biggest rice producer province in iran, are essential and helpful in reducing rice losses. a research was undertaken to examine the effects of variety (tarom, hibrid, and fajr), milling machine (frictional and abrasive baed mill...
In the present paper we show that a stem finite p -group G has size bounded by min ( 8 d − 2 log + b 4 ) 1 / , 3 where is breadth of and maximum character degree . As consequence there are only finitely many -groups having
Bell's degree-variance Var$!{}_{B}$ for a graph $G$, with the degree sequence ($d_1,d_2,cdots,d_n$) and size $m$, is defined as$Var!_{B} (G)=frac{1}{n} sum _{i=1}^{n}left[d_{i} -frac{2m}{n}right]^{2}$.In this paper, a new version of the irregularity measures of variance-type, denoted by $Var_q$, is introduced and discussed. Based on a comparative study, it is demonstrated that the n...
at early stages of new product development, the effort tooptimize is low and effects on the whole innovation process are high.therefore, a deeper understanding of fuzzy front end and its successcan help firms to be more successful in developing new products. wepresented and tested a conceptual model of relationships among keyvariable sre lated to the fuzzy front end,execution phase of new produ...
Investigating transfer of one’s pragmatic knowledge of first language to his second or foreign language has been one of the areas of interest for researchers. However, there are contradictory results even within the scarce studies which have addressed transferability. This study was an attempt to investigate perceived pragmatic transferability of L1 refusal strategies by Persian EFL learners. S...
