the major aim of this study was to investigate the relationship between social and cultural capital and efl students’ critical thinking skills. this study takes this relationship in to account to see if people with different sociocultural status are different regarding their critical thinking skills. to this end, 160 university students majoring in english language and literature, english trans...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
in this research the effect of randomly reinforced soil and soil cement with different percent of cement and fiber and different length of fiber was investigated. samples were prepared according to the maximum dry unit weight and optimum water content due to the corresponding compaction curves. compressive and tensile strength were conducted on samples for different curing times. regression equ...
This study aims at comparing the performance of MaxEnt and logistic regression in preparing the predictive habitat distribution map of Thymus kotschyanus and determining the factors affecting in the northern of Ardabil Province rangelands. 28 sites were selected and at each site, three transects with a length of 100 m and on each transect ten 1m2 plots were established. Soil samples were taken ...
Long-term measurements of soil nitrogen (N) transformations along an environmental gradient within the Coweeta Hydrologic Laboratory basin in western North Carolina showed a strong seasonal pattern and suggested that vegetation community typethrough its influence on soil properties-was an important regulating factor. Our objective was to determine the relative effects of biotic vs. abiotic fact...
Water susceptible properties of subgrade soils play important role in the structural design of highways. In this research study laboratory investigations were conducted on subgrade soil samples for determining the influence of water susceptible properties on Natural moisture content, Optimum moisture content, Compaction, California Bearing Ratio (CBR)-soaked and unsoaked, and Unconfined Compres...
in general, amount of sludge will definitely increase in near future and composting processes, optimum composting conditions and compost use as fertilizer and soil amendment will then be significant research topics. the present study was conducted for o2 parameter estimation by multiple regression and artificial neural networks methods. daily temperature, ch4, h2s, co2 and o2 measurements were ...
In order to provide a relatively simple means of predicting live herbaceous plant moisture content from a readily available meteorological index with an accuracy adequate for fire hazard assessment, the moisture content fluctuations of certain species were correlated with the values of a seasonal drought index based on soil moisture deficiency. The simple linear regression models provided the b...
Surface soil moisture is an important variable that plays a crucial role in the management of water and soil resources. Estimating this parameter is one of the important applications of remote sensing. One of the remote sensing techniques for precise estimation of this parameter is data-driven models. In this study, volumetric soil moisture content was estimated using data-driven models, suppor...
