this study aims to assess the effect of grazing intensity on vegetation structure, soil nutrient concentrations and soil physical properties. the study was carried out in steppe rangelands of saveh, markazi province, iran. four sites with four grazing intensities including very high, high, moderate and non-grazed with the same ecological conditions were selected. to study various vegetation and...
The remote sensing ecological index (RSEI) has been widely used in the rapid monitoring and evaluation of regional environment; however, research on main factors that cause changes RSEI impact human activities mining area is not often explored. To this end, paper selected Landsat (TM/OLI) series images from 1986 to 2022; extracted four important indicators normalized difference vegetation (NDVI...
Drought stress is an important limiting factor for plant growth. Using selection indices, it is possible to identify cultivars with high yield in normal and stressed conditions. So, the genetic analysis of drought tolerance indices can play important role in plant breeding programs. In order to identify molecular markers linked with drought tolerance indices in sunflower, 72 recombinant inbre...
Abstract Aims & Backgrounds: Today, economic challenges are one of the most important obstacles to achieving sustainability in the cities of developing countries. Therefore, recognition and geographical analysis of the factors affecting the economic sustainability of cities are among the important goals and priorities of urban and regional planning. Methodology: This research has been done by q...
background : infantile obesity is becoming increasingly recognized as one of the public health problems in iran. objective: obesity charts of a cohort of 317 healthy infants and their parents living in shiraz (southern iran) are presented and the familial pattern of infants’ obesity with that of its parents explored. methods : an adjusted weight-for-height index was used to develop power ty...
Drought is a complex phenomenon caused by the breaking of water balance and it has always an impact on agricultural, ecological and socio-economic spheres. Although the drought indices deriving from remote sensing data have been used to monitor meteorological or agricultural drought, there are no indices that can suitably reflect the comprehensive information of drought from meteorological to a...
This study was conducted at Research Farm of Isfahan University of Technology to evaluate drought tolerance potential of 23 F2:4 wheat lines derived from the cross of Virmarin (susceptible line) and Sardari (tolerant line). A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3 and 120±3 mm evaporation from class A pan for ...
Abstract The rapid economic development and high incidence of crises in emerging economies make them play an increasingly important role the transmission global financial risks. As a new trend industry, green finance also indicates direction future industry. Faced with concerned environmental issues, it is necessary for economies, mainly represented by developing countries, to learn from experi...
Background and Aims: Nurses face too much stressors as work-rest cycle problems, overload responsibility, lack of vacation time and painful experiences of patients; therefore, resiliency can help them to appropriate and efficient cope with these stressors. But, there is no brief and practical scale to assess psychological resiliency among nurses in Iran. So, the aim of the present study was to ...
