this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
spatial-temporal modeling of air pollutants, ground-level ozone concentrations in particular, has attracted recent attention because by using spatial-temporal modeling, can analyze, interpolate or predict ozone levels at any location. in this paper we consider daily averages of troposphere ozone over tehran city. for eliminating the trend of data, a dynamic linear model is used, then some featu...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
One of the major challenges of Interferometric Synthetic Aperture Radar (InSAR) technique is the existence of tropospheric effect on the results. The tropospheric effect is due to the changes of atmospheric parameters including temperature, pressure, and humidity between the master and slave images. In this research, two different methods based on spatial-temporal filters and calculation of pha...
Despite considerable enhances in recognizing hand gestures from still images, there are still many challenges in the classification of hand gestures in videos. The latter comes with more challenges, including higher computational complexity and arduous task of representing temporal features. Hand movement dynamics, represented by temporal features, have to be extracted by analyzing the total fr...
the objective of this study was to determine the effects of different heel heights on selected gait parameters in a sample of young nigerian females. a purposive sample of eighty apparently healthy undergraduates of nnamdi azikiwe university, nnewi campus participated in the study. their mean age, height, and weight were 21.98± 1.83 years, 1.65±0.06 meters, 59.50±9.34 kilograms respectively. an...
Background: The aim of the study was to assess the effect of an 8-week balance exercise program for enhancement of gait function on temporal and spatial parameters of school aged children with intellectual disabilities. Method: Forty young people with intellectual disabilities were assigned either to the balance exercise program for enhancement of gait function group (BG group, n=19) or the ...
the environmental and ecological issues in the flow-reduced river reach are very serious and arereceiving increasingly attention. in this study, we investigate the temporal and spatial changes in δ13c and δ15n of periphyton and isotopic relationship between periphyton and the endangered fish (ayu, plecoglossusaltivelis) in a flow-reduced river reach in japan. much of the spatial and temporal va...
the present study aimed to monitor the land use change in the shazand watershed with different development policies using land use net changes and exchanges in land change modeller (lcm) forperiod of1973to2014and in sub-watersheds scale. in the study period, rangeland area reduced about 380 km2 and rainfed and irrigation farm lands increased successively 100 and 150 km2 in the first and the sec...
. introduction the siberian high (sh) is a quasi-stationary and semi-permanent surface high pressure system residing over the eurasian continent during winter with its climatological–mean central pressure exceeding 1030 hpa. this most important atmospheric center of action controls the climate of a wide area of this continent. the sh forms generally in october mainly in response to strong radia...
