Background & Aims: Uroflowmetry is a common procedure to examine the lower urinary tract system. Uroflowmetry results are affected by different factors. In this study, the effect of voiding position on uroflowmetric parameters and voiding residue were investigated in healthy subjects. Methods: This descriptive–analysis study was performed on 41 healthy volunteers with mean age of 33.22 ± 9.45 r...

Given an arbitrary n, we consider anisotropic quadratic forms of dimension n over all fields of characteristic = 2 and prove that the height of an n-dimensional excellent form (depending on n only) is the (precise) lower bound of the heights of all forms of dimension n.

a trial study was carried out to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on wheat yield and components, at the agricultural faculty of shahidchamran university of ahvaz during 2011-2012.the experimental design was splitplot at randomized completed block design arrangement. the main plot were different wheat residue manage...

The literature of pesticide residue analysis is reviewed selectively for the period 1999-2000. Analyses of a wide range of pesticide classes and sample types, as well as some related organic pollutants, are covered. Studies of exposure and monitoring as well as pesticide degradation, persistance, leaching, mobility, and metabolism studies are included.
