introduction: the selection of   optimal treatment of obstructive nephrouropathy requires information about the functional status of each kidney. nuclear renal scanning objectively measure differential renal function, multiple studies have demonstrated the role of assessment of renal perfusion and gfr with triphasic ct. the aim of this study is to assess the role of ct based on renal parenchyma...

The takeover time of some selection method is the expected number of iterations of this selection method until the entire population consists of copies of the best individual under the assumption that the initial population consists of a single copy of the best individual. We consider a class of nongenerational selection rules that run the risk of loosing all copies of the best individual with ...

literatures have reported that a lot of drought related genes were cloned and individual gene showed positive effects under controlled stress experiments, but were not much effective in the field. although, the progresses by conventional breeding approaches were achievable as some drought varieties have been released to the farmers in the recent years but this is not adequate to cope up with th...

in order to select the suitable lines of red bean for chahharmahal & bakhtiari province, this experiment was conducted in lordegan & boldaji regions at 2001-2005. at the first year, single plants of local red bean (from lordegan, ardal, boldaji, dastgerd emamzadeh and gandoman regions) were selected at research farm for phenotypic characters, yield and yield components. at the second year, sele...

The description of the project suggests that the study was designed to investigate the effects of incinerator emissions on the local population in two suburbs of Antwerp, Belgium, Wilrijk and Hoboken. However, the study was part of a larger research project commissioned by the Flemish government to determine the feasibility and issues to be considered in developing environmental health monitori...

Individual differences studies are those that investigate the interaction between a subject level covariate, such as sex, age, or performance, and the effect of an experimental task. Commonly, a brain region is selected on the basis of the task effect, and the signal in this region correlated with individual covariates. It is shown here that, provided that data are identically and independently...

The increasing size of data sets has lead to variable selection in regression becoming increasingly important. Bayesian approaches are attractive since they allow uncertainty about the choice of variables to be formally included in the analysis. The application of fully Bayesian variable selection methods to large data sets is computationally challenging. We describe an adaptive Markov chain Mo...

The selection of sperm cells possessing normal morphology and motility is crucial for many assisted reproductive technologies (ART), especially for intracytoplasmic sperm injection (ICSI), as sperm quality directly affects the probability of inducing healthy pregnancy. We present a novel platform for real-time quantitative analysis and selection of individual sperm cells without staining. Towar...

-This article, which focuses on hormones and the diverse effects they have on behavior and physiology, raises evolutionary questions that hormonal studies appear especially well suited to address. These include the endocrine basis for life-history trade-offs, the role of hormones in adaptive alterations in social organization and mating systems, and whether natural selection acts on traits or o...
