introduction: soil aggregate stability is a key factor in soil resistivity to mechanical stresses, including the impacts of rainfall and surface runoff, and thus to water erosion (canasveras et al., 2010). various indicators have been proposed to characterize and quantify soil aggregate stability, for example percentage of water-stable aggregates (wsa), mean weight diameter (mwd), geometric mea...
in this paper, a new formula is applied for the calculation of gravity anomalies from a cylinder model representing a geological body. compared to conventional methods, this new development allows the cylinder to be freely oriented in space. 38 gravity forward models are produced each of which anomaly attributes are calculated. then a linear relationship is established between attributes and so...
Abstract: In this study an appropriate computational approach was presented for estimating the boiling temperatures of 41 different types of olefins and their derivatives. Based on the guidelines of this approach, several structural indices related to the organic components were applied using graph theory. Meanwhile, in addition to evaluating the relation between the boiling temperatures of ole...
background: disability is the most important determinants of disease course, treatment and rehabilitation outcomes and consequently the quality of life in patients with multiple sclerosis. the aim of the present study was to determine the relationship of disability and quality of life in multiple sclerosis patients. methods: this cross-sectional study was performed on 325 patients referred to...
evaporation is one of the main parameters for the optimum operation of reservoirs, design of irrigation systems and scientific management of water resources. accurate estimation of the water evaporation level is crucial in any region especially in arid and semiarid regions. in this study, the feasibility of simulation of pan evaporation in maraghe station using the multiple regression models we...
multiple linear regression study of 2,4-disubstituted 1,5-benzodiazepine as potential antiinfectives
this paper describes 3d-qsar analysis and biological evaluation of 1,5-benzodiazepine analogues. benzodiazepine nucleus with its simple structure gives a good opportunity for further modification regarding an increase of its antimicrobial activity. we synthesized a series of benzodiazepine analogues from condensation of various chalcones and halo substituted o-phenelynene diamines. all compound...
