Evolution and Testing of the Lacunar Hypothesis" by Bamford and Warlow in this issue of Stroke reviews many important aspects of these unique pathologic vascular lesions. I concur with the authors' emphasis on the need to maintain homogeneity in the classification of stroke conditions, specifically lacunes. A stroke classification scheme would ideally be based on 1) risk factor profile such as ...

We survey the recent applications and developments of sieve methods related to discrete groups, especially in the case of infinite index subgroups of arithmetic groups.

riparian vegetation is a component of river system that performs certain basic functions including primary vegetative production, protecting stream banks from erosion, trapping sediments, promoting water quality, wildlife habitat and fisheris, forage for livestock, etc. in this research, spatio-temporal change of vegetation riparian area of aghbolagh-river as an upstream of karoon-river for 65-...

Background & Aims of the Study: Vegetables are useful for humans as they contain minerals, vitamins, fiber and other nutrients. Eating raw vegetables are a nutritional habit in Iranian families. Raw eating vegetables is the main source of parasitic infections. The aim of this study was to determine microbial contamination of raw vegetables in Ahvaz, Iran during 2014-2015. ...

The effect of seed inoculation by phosphate solubilizing microorganisms and different levels of phosphorus chemical fertilizer on yield and yield components of barley (Karoon x Kavir cultivar) was studied in Experimental Farm of College of Agronomy and Animal Sciences, University of Tehran during 2006-2007 growing seasons. The experimental treatments were arranged in split plot factorial based ...

A methodology based on adaptive ANN models is proposed for flood routing in river systems. The proposed methodology is capable of modeling both converging and diverging river networks. A Multilayer Perceptron Network (MLP), a Recurrent Neural Network (RNN), a Time Delay Neural Network (TDNN) and a Time Delay Recurrent Neural Network (TDRNN) are applied in this study. An Adaptive training proced...

the aim of this investigation was to study macroscopic and microscopic structures of ovaries in barbus grypus of karoon river and their changes during annual maturation cycle. for this purpose, 120 adult  b.grypus with a mean weight of 835.0 to 1012.0 g, were caught from karoon river and transferred alive to the laboratory. after biometrical studies, the weights and morphological appearances of...

the tele-connection patterns are the major constituents of climate at global and regional scale(s). the karoon basin is of a vital stance in providing natural water supply and hydroelectric; this basin is facing major fluctuations in rainfall regime. identifying the effect of tele-connection on great karoon basin rainfall regime is the subject of this study. to accomplish this objective the sea...
