Optimal allocation of Var source involves optimal location and determination of the size of the Var source. The purpose is to find the right tradeoff between the investment cost of the new Var source and the benefits in system operation derived from the presence of the additional reactive compensators. Traditionally, the locations for placing new Var sources were either simply estimated or dire...
The vast burden of cryptococcal meningitis occurs in immunosuppressed patients, driven by HIV, and is caused by Cryptococcus neoformans var. grubii. We previously reported cryptococcal meningitis in Vietnam arising atypically in HIV uninfected, apparently immunocompetent patients, caused by a single amplified fragment length polymorphism (AFLP) cluster of C. neoformans var. grubii (VNIγ). This ...
Legumes build soil fertility and contribute substantial amounts of N for sustainability of cereal based cropping systems. These lacking information for the system as a whole in rainfed pothwar were investigated through field experiments at two different locations i.e. (Research farm of University of Arid Agriculture Rawalpindi, UAAR and farmer’s fields in Chakwal district). Mung bean (Var. NM-9...
The essential oils obtained by steam distillation from needles of six China endemic Pinus taxa (P. tabulaeformis, P. tabulaeformis f. shekanensis, P. tabulaeformis var. mukdensis, P. tabulaeformis var. umbraculifera, P. henryi and P. massoniana) were analysed by GC/MS. A total of 72 components were separated and identified by GC/MS from the six taxa. The major constituents of the essential oils...
The conditional Gauss–Hermite filter (CGHF) utilizes a decomposition of the filter density p(y1, y2) into the product of the conditional density p(y1|y2) with p(y2) where the state vector y is partitioned into (y1, y2). In contrast to the usual Gauss–Hermite filter (GHF) it is assumed that the product terms can be approximated by Gaussians. Due to the nonlinear dependence of φ(y1|y2) from y2, q...
The Su(var)3-7 gene, a haplo-suppressor and triplo-enhancer of position-effect variegation (PEV), encodes a zinc finger heterochromatin-associated protein. To understand the role of this protein in heterochromatin and genomic silencing, mutations were generated by homologous recombination. The donor fragment contained a yellow(+) gene and 7.6 kb of the Su(var)3-7 gene inserted between two FRTs....
در چند سال اخیر مدل های ارزش در معرض ریسک از اصلی ترین مدل های اندازه گیری ریسک خصوصاًریسک بازار محسوب می شوند و این در حالی است که با توجه به استفاده مدل های var از داده های تاریخی بر اساس آثار دوره قبل از بحران های مالی، نوسانات var در دوره بحران در اغلب موارد به طور صحیح مدل سازی نمی شود. هدف از تحقیق حاضر، ارزیابی عملکرد 4 مدل ارزش در معرض ریسک (var ساده،var ریسک متریک،garch(1,1)،gjr-garch)...
Histone modifications are important regulators of gene expression in all eukaryotes. In Plasmodium falciparum, these epigenetic marks regulate expression of genes involved in several aspects of host-parasite interactions, including antigenic variation. While the identities and genomic positions of many histone modifications have now been cataloged, how they are targeted to defined genomic regio...
بیمه یکی از ابزار مهم و اساسی در دنیای متمدن امروزی است که نقش بسزایی در کاهش ریسک و تامین امنیت مالی و ذهنی و در نهایت ایجاد بسترهای لازم برای توسعه اقتصادی کشور دارد. هدف اصلی این تحقیق بررسی عوامل موثر بر تقاضای بیمه عمر در ایران، طی سالهای ( 1388 - 1358 ) می باشد. عوامل موثر برتقاضای بیمه عمر در ایران تابعی از درآمد سرانه واقعی، نرخ تورم انتظاری، نرخ پس انداز، نرخ بهره و نرخ باسوادی در نظر ...
