In the wake of the greenhouse effect and global energy crisis, finding sources of clean, alternative energy and developing everyday life applications have become urgent tasks. This study proposes the development of an "autonomous house" emphasizing the use of modern green energy technology to reduce environmental load, achieve energy autonomy and use energy intelligently in order to create a su...

today, environmental threats are in center of important questions’ human conscience twenty-first century. these questions have attracted public opinions quit alarming and they posed extreme sensitivity to the environment on a global level. this study aimed at understanding the role of social structural factors on the gap between environmental attitudes and behavior carried out. population invol...

Theory relating species richness to ecosystem variability typically ignores the potential for environmental variability to promote species coexistence. Failure to account for fluctuation-dependent coexistence may explain deviations from the expected negative diversity-ecosystem variability relationship, and limits our ability to predict the consequences of increases in environmental variability...

the aim of this research is to analyze the environmental principals which are used for land use planning of iranian communities in order to determine whether they are sufficient and efficient for conserving and improving the quality of urban environments or not. first, the environmental principals were extracted from municipal local plans (community plans) of the spatial planning systems of ira...

As the energy cost is rising steadily and the environmental pollution is becoming an important issue, the roles of process plant boilers like that of the sugar plants boilers need better understanding as they can be made to operate in either energy conserving or bio-mass conserving modes. However, practical models of the plants need to be developed before any effort at optimization and cogenera...

We consider mass-conserving self-similar solutions of Smoluchowski’s coagulation equation with multiplicative kernel of homogeneity 2λ ∈ (0, 1). We establish rigorously that such solutions exhibit a singular behavior of the form x−(1+2λ) as x → 0. This property had been conjectured, but only weaker results had been available up to now.

In this paper we summarize the results of a workshop conducted to disseminate information about community-based research on the environmental health risks of exposure of farmworkers to pesticides. Community-based research is an approach that is advocated for addressing issues of environmental justice such as exposure of farmworkers to pesticides. This workshop brought together scientists, commu...
