abstract the objective of current research is to investigate distribution patterns of vegetation types and its relation with environmental factors in southern margin of haj aligholi kavir of damghan. three vegetation types including halecnemum strobilaceum, sedlitzia rosmarinus and artemisia sieberi were studied in marginal arid regions and uplands of the study area. firstly, geographic locatio...
This research was aimed to simulate and prioritize the effective factors on water erosion using USLE-M in the system dynamic model. In this integrated model, by using the system dynamic simulation software (Vensim), all variables and factors involved in erosion and soil loss were considered according to the USLE-M model. After model implementation, the estimated values and observations were com...
Predicting dust sources area and determining the affecting factors is necessary in order to prioritize management and practice deal with desertification due to wind erosion in arid areas. Therefore, this study aimed to evaluate the application of three machine learning models (including generalized linear model, artificial neural network, random forest) to predict the vulnerability of dust cent...
This paper presents an inverse analysis of the unobserved trigger factors with respect to the slope failures based on the Structural Equation Modeling (SEM). The quantitative prediction models generally construct the relationship between the past slope failures and the causal factors (i.e. lithology, soil, slope, aspect, etc.), but does not deal with the trigger factors(i.e. rail fall, earthqua...
this study tries to make a distinction between factors affecting adopters and non-adopters of domestic rainwater harvesting (drwh) in golestan province, iran. in order to better comprehend the differences, nine dimensions were considered in this study, including (1) social background (including respondents’ demographics, water sources, issues in accessing water sources, primary awareness of the...
The trial carried for the two repeated years, start from rabi seasons of years 2021-22 at research farm, department soil science and agricultural chemistry, [NAI], SHUATS, Prayagraj. excavated sample experimental site before conducting operation, mentioned that, land topography range was nearly levelled with 1-3% slope, among nine treatments, during field experimentation, conjunctive use NPK di...
Ecophysiography is the geography of the earth and the relationship between physiography and the ecosystem. Ecophysiography is a basis for planning processes to study the characteristics of terrestrial systems concerning the interactions between terrestrial physiography and living organisms. Due to the current state of ecosystems and the increase in natural disasters for ecosystem sustainability...
the analysis of the relationship between spatial distribution of environmental factors andvegetation types is crucial for understanding mountainous ecosystems. in this research agis based approach was used to produce a vegetation map for sabzkouh protected area inthe chaharmahal-va-bakhtiari province. to identify environmental parameters affecting thevegetation cover, 6 primary and secondary en...
This study describes a population pharmacokinetic meta-analysis of propofol to characterize the influence of body size measures and age in morbidly obese and nonobese adults, adolescents, and children. Sixty morbidly obese and nonobese adult patients (55-167 kg; 21-79 years) and 34 morbidly obese and nonobese adolescents and children (37-184 kg; 9-20 years) were included. The results show that ...
