objective: metal concentrations in 53 soil samples of shahr-e-babak were determined. methods: assessment of enrichment factor and geo-accumulation index revealed higher degree of contamination of cd, pb, and cu in soil samples. moreover, results of metal fractionation study revealed high amount of cd and pb are associated in weakly bounds may lead to environmental risk of these metals. result...
for a nite group g the commutativity degree denote by d(g) and de nd: d(g) = jf(x; y)jx; y 2 g; xy = yxgj jgj2 : in [2] authors found commutativity degree for some groups,in this paper we nd commuta- tivity degree for a class of groups that have high nilpontencies.
چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
Two-person noncooperative games with finitely many pure strategies and ordinal preferences over pure outcomes are considered, in which probability distributions resulting from mixed strategies are evaluated according to t-degree stochastic dominance. A t-best reply is a strategy that induces a t-degree stochastically undominated distribution, and a t-equilibrium is a pair of t-best replies. The...
financial protection against health expenditures is a major goal of health system policymaking. governments have focused on the risk that high health expenditures pose to the financial security of deprived and vulnerable populations. Health systems need to be sure that people receive health services and are protected from the financial burden of health costs. There is no accepted standard for m...
The toxicity of heavy metals in sediments of the Nayband Bay and Asaluyeh region and potential ecological risk to sediment organisms assessed. Three stations with different degrees of vulnerability of South Pars Oil and Gas Activities (1: Control - 2: medium affected and 3: severely affected) were selected in the study area. Sediment sampling at each station in both cold and hot seasons (2010) ...
Many insights regarding rank-order tournaments rest upon contestants’ behavior in symmetric equilibria. As shown by Gill and Stone (2010), however, symmetric equilibria may not exist if contestants are expectation-based loss averse and have choice-acclimating expectations. We show that under choice-unacclimating—i.e., fixed— expectations both symmetric and asymmetric equilibria exist for all de...
Background: To identify the risk factors of fourth-degree laceration during vaginal delivery. Methods: This is a retrospective, case control study. We reviewed 131802 records of vaginal deliveries within 14 years period from 1990 to 2004 in two obstetric center. Cases were 93 vaginal deliveries with fourth-degree laceration and 7 cases were delivered at home, control subjects were 200 vaginal...
financial companies are constantly exposed to the dangers of risk. in the last few years for various reasons, measuring value at risk (var) has become increasingly important for financial firms. the study of multiple measures of risk, var measure with a new approach provides the ground for calculation of market risk. common approaches to risk measurement due to complicated, nonlinear and changi...
Background and aims: Today, due to the increasing of urban population and hence land shortage, construction of tall buildings are rising . The potential risks of such projects arecomparatively more than the conventional construction as the construction industry is reliant on manpower. Therefore attention to the health and safety of persons engaged in construction projects is essential.The pur...
