in this work some quantitative structure activity relationship models were developed for prediction of three bioenvironmental parameters of 28 volatile organic compounds, which are used in assessing the behavior of pollutants in soil. these parameters are; half-life, non dimensional effective degradation rate constant and effective péclet number in two type of soil. the most effective descripto...

The geogrid-reinforced soil structures play important roles in the reinforcement applications since 1980s. Generally in design of the geogrid-reinforced soil structures, the soil-geogrid interaction behavior is not directly considered. Instead, the interaction strength is represented by the consolidation drained strength of soil commonly. However, neglecting the effect of compaction and suction...

A number of nonlinear models have recently been proposed for simulating soil carbon decomposition. Their predictions of soil carbon responses to fresh litter input and warming differ significantly from conventional linear models. Using both stability analysis and numerical simulations, we showed that two of those nonlinear models (a two-pool model and a three-pool model) exhibit damped oscillat...

this paper deals with the concept of “residential models” and the role it plays on human relations in residential complexes. it intends to; review the concept of residence; understand how a residential model takes form; the influence of a residential model on future human interactions. to this end, having reviewed comments and viewpoints, focused on “what is residence? which factors may create ...

The significance of the seismic rotational components have been overlooked in the seismic evaluation of structural behavior. As researchers have measured seismic components more accurately using sensitive rotational velocity sensor, it was observed that the magnitude of rotational components is considerable and could not be neglected. Hence, some parts of seismic damage or failure of structures...

Multiple soil moisture products have been generated from data acquired by satellite. However, these satellite soil moisture products are not spatially or temporally complete, primarily due to track changes, radio-frequency interference, dense vegetation, and frozen soil. These deficiencies limit the application of soil moisture in land surface process simulation, climatic modeling, and global c...

ABSTRACT: The aim of this paper is to model the rate-dependent behavior of soft soil by means of a microstructural approach. A new microstructural elasto-viscoplastic model was developed, based on the granular mechanics approach and the overstress theory of Perzyna. The deformation of a representative volume of the material is generated by mobilizing particle contacts. Thus, the stress-strain r...

aim: investigating factors affecting the adoption of preventive behaviors in women with osteoporosis is necessary. this study aims at determining the preventive treatment of osteoporosis in women in fasa using the health belief model (hbm) during 2014. method: in this cross-sectional study, 401 women (aged 30-50 years) covered by the health centers in fasa city were randomly chosen. construct o...

conclusions the current study provided evidence for the utility of the belief-based model in the prediction of oral health behaviors. it could be suggested that oral health behavior can be promoted by reducing the perceived barriers and enhancing the students’ knowledge of oral and dental hygiene. background oral and dental health diseases can affect the general health of students. objectives t...

In this article we explore sources and magnitude of positive and negative error in soil ingestion estimates for children on a subject-week and trace element basis. Errors varied among trace elements. Yttrium and zirconium displayed predominantly negative error; titanium and vanadium usually displayed positive error. These factors lead to underestimation of soil ingestion estimates by yttrium an...
