The relationships between the intensification rate (IR) and size configuration of tropical cyclones (TCs) are investigated. Theoretically, intensity, configuration, relative vorticity TCs intrinsically linked. TC fullness (TCF) is used to quantify can be expressed as product critical (TCF0) ratio (Rf). TCF0 represents fundamental constraint on shared by at a given intensity lower limit fullness...

Abstract Mechanisms driving the consumption and transport of tidal marsh nutrients energy by fishes are key interest in San Francisco Estuary, CA, USA. By combining multiple data sources (gill-net catches, gut contents, channel morphology, tides), we modeled spatial temporal patterns fish abundance fullness across a elevation gradient. Channel depth, microhabitat, tide were important predictors...

in order to evaluate the physiological indices in relation to the screening of spring safflower genotypes for drought tolerance and productivity, seed and oil yields and yield components were measured for five genotypes including local arak, local esfahan, sina, kh23 – 57 and goldasht. the study was conducted in a loam soil in east azarbaijan, iran, during three successive years (2005-2007)...

background: reference percentile curves are usually used as a screening tool to determine growth disorders. anthropometric indices are population-dependent and may differ according to ethnicity, dietary pattern and lifestyle habits. this study aims to compare the curves of anthropometric measures obtained in two national studies conducted among iranian children and adolescents in 2003-2004 and ...
