Environmental (topography, climate) features have an important influence on plant diversity and richness of Iran. Topography is from –28m which is close to Caspian Sea to 5678m which is located on the Alborz Mountain. Two mountains (Alborz and Zagrosss) prevent moist air moving to the centre of Iran. On the basis of environmental factors, four ecological zones with specific plant richness from ...

background change theories provide an opportunity for organizational managers to plan, monitor and evaluate changes using a framework which enable them, among others, to show a fast response to environmental fluctuations and to predict the changing patterns of individuals and technology. the current study aimed to explore whether the change in the public accounting system of the iranian health ...

a comprehensive assessment of drought environmental and socio-economic impacts provides critical information to rational decisions supporting drought mitigation policies and programs. the objectives of this study were to survey environmental and socio-economic impacts of drought in guilan province, and prioritize them from the viewpoint of paddy farmers. this study was a descriptive-correlation...

The ecosystem services (ES) approach is gaining broad interest in regulatory and policy arenas for use in landscape management and ecological risk assessment. It has the potential to bring greater ecological relevance to the setting of environmental protection goals and to the assessment of the ecological risk posed by chemicals. A workshop, organised under the auspices of the Society of Enviro...

this research was conducted to investigate genotyp×environment interaction for grain yield of ten wheat cultivars in 8 environments (combinations of two nitrogen fertilizer treatment and four irrigation regimes). analysis of additive main effects (analysis of variance) and multiplicative interaction effects (principal component analysis) revealed that the effects of genotype, environment and ge...

Background: Food waste is a very serious problem, it is proven that Indonesia is the second largest producer of food waste in the world. A limited waste management system will result in a decrease in environmental quality such as air pollution, water pollution, and soil pollution. So far, the waste management system is only limited to reducing waste generation. Life Cycle Assessment (LCA) is a ...

Detecting outlying observations is an important step in any analysis, even when robust estimates are used. In particular, the robustified Mahalanobis distance is a natural measure of outlyingness if one focuses on ellipsoidal distributions. However, it is well known that the asymptotic chi-square approximation for the cutoff value of the Mahalanobis distance based on several robust estimates (l...
