the offered approach is based on the establishment of the functional dependence between river water discharge (q) and suspended ms ,in a number of observations, which noticeably differs from the mean value (r) of subsequent allocated period(s). the earliest period anthropogenic component during the subsequent period(s) is the difference between an actual suspended sediment yield and its hypothe...

the purpose of this paper is to investigate the differences in value of children between the 1960s, 1970s, after 1980 birth cohort, and identifying the factors affecting. the data for this study are drawn from a survey in semnan province in 2012. information is related to 405 married women aged 15-49 years. the result shows that the highest score of the children value belonged to the 1960 birth...

BACKGROUND AND OBJECTIVE Skin color and self-reported ethnicity have systematically been used in the pharmacogenetic/-genomic literature as phenotypic proxies for geographical ancestry. Population admixture, however, challenges the appropriateness of this approach. We compared the effectiveness of color-based and marker-based biogeographical ancestry classifications in typing polymorphisms in G...

BACKGROUND Glutathione S-transferase M1 (GSTM1) have been reported to be associated with hepatocellular carcinoma. However, the effect of the GSTM1 null genotype was divergent in the literature and we therefore performed the present meta-analysis to explore the relationship in detail. MATERIALS AND METHODS Reported studies were searched from 1990 to March 1, 2014 in PubMed and Wanfang Med Onl...

Workflow management systems usually interpret a workflow definition rigidly, allowing no deviations during execution. However, there are real life situations where users should be allowed to deviate from the prescribed static workflow definition for various reasons, including lack of information about parameter values and unavailability of the required resources. To flexibilize workflow executi...

BACKGROUND Endometriosis is one of the most common gynecologic disorders. It is a complex trait and both genetic and environmental factors have been implicated in its pathogenesis. There is growing evidence indicating that exposure to environmental contaminants is a risk factor for endometriosis. Glutathione-S-Transferase M1 (GSTM1) is one of the genes involved in detoxification of endogenous a...

An interval problem is a problem where the unknown variables take interval values. Such a problem can be defined by interval constraints, such as "the interval [a, b] ⊂ [a, b]2". Interval problems often appear when we want to analyze the behavior of an interval solver. To solve interval problems, we propose to transform the constraints on intervals into constraints on their bounds. For instance...

The radiant energy incident on the retina of a human viewing: the noon-day sun is calculated as 4.25 cal./cm.'-'-sec. with an image diameter of 0.16 mm., assuming an atmospheric transmission of 85'/( and a pupil diameter of 2.6 mm. The retinal irradiance under the limiting conditions of 100% atmospheric transmission and 6 mm. pupil diameter is shown to be only 29 cal./cm.-'-sec. This retinal ir...

Many studies have reported an association between the glutathione S-transferase M1 null and T1 null polymorphisms and lung cancer risk. However, the combined effects of GSTM1 null and GSTT1 null polymorphisms have not been reported previously. We, therefore, performed a meta-analysis to investigate the combined effects. 40 publications with 44 case-control studies were selected in the meta-anal...

BACKGROUND Glutathione S transferase (GST) polymorphisms have been considered as risk factors for age-related cataracts, but the results remain controversial. In this study, we have performed a meta-analysis to evaluate the association between polymorphisms of GSTM1 and GSTT1 and cataract risk. METHODS Published literature from PubMed and other databases were retrieved. The case-control studi...
