The term "horse-racing effect" refers to a positive correlation between the slope at which blood pressure increases with age and blood pressure level at a baseline. Previous studies have reported such an effect in adults, while studies in children have found a negative correlation (termed "the Jenss effect"). These studies used analytic methods in which it was assumed that the blood pressure sl...

this study aimed to determine the prone areas for sugar beet planting with regards to their major effective factors. climatic data of 1998-2009 period were obtained from the local stations of khorasan razavi meteorological bureau. the topographic data including altitude, slope, slope direction, and tin layers were extracted from 1:250000 topographic maps of cartographic organization, iran. the ...

in recent years there has been studies concerning the investigation of macro-scale geomorphic proxies of quaternary climatic changes in the study area. without detail analysis of slope geomorphic features, there can be little progress on expanding the knowledge of past slope development in the northwestern iran high mountain environments. consequently, the information pertaining to these quater...

BACKGROUND AND PURPOSE This study sought to determine the degree of agreement between asymmetries of neuropsychological functioning and nine methods of quantifying asymmetries of regional cerebral blood flow. METHODS The regional cerebral blood flow methods combined three markers of cerebral blood flow asymmetry (percent hemispheric difference, maximum percent probe-pair asymmetry, and number...

the main purpose of this study is landslide hazard assessment the ziarat watershed (golestan province) using information value and lnrf models within geographic information. at first stage, a landslide inventory map was prepared in the study area using earlier reports and aerial photographs, and a total of 50 landslides was mapped and out of which 35 (70%) were randomly selected for building la...

In order to sustainable use of rangelands, it is necessary to recognize water, soil, and vegetation cover and analyze their relationships. Physical and chemical properties of soil are effective in distribution of plant species in local area. To determine the effects of some soil properties on species distribution of Eurotia ceratoides and Stipa barbata in Baghedar summer region of Bafgh, three ...
