in rural areas, where water tends to be traded less and is mostly used as an essential farm input, water users association can be as an alternative for water resource management. the purpose of this study was to investigate influence factors on the farmers’ tend to constitute water users associations. research population was all farmers covered of feyzabad irrigation network supply (192 farmers...

Patterns in biomass production are determined by resource input (productivity) and trophic transfer efficiency. At fixed resource input, variation in consumer biomass production has been related to food quality, metabolic type and diversity among species. In contrast, intraspecific variation in individual body size because of ontogenetic development, which characterizes the overwhelming majorit...

This paper summarizes and comments on Conner (1991) that contributes to the strategic management area by providing an historical comparison of resource-based theory and five schools of thought within industrial organization economics. Conner (1991) argues that the fundamental distinction between resource-based theory and transaction costs theory is that resource-based theory focuses on the depl...

Geographic variation in resource use can produce locally adapted populations that exhibit genetic and phenotypic divergence. In the bird-winged grasshopper (Schistocerca emarginata = [lineata]), we investigate whether genetic data exist in accordance with geographic variation in resource (host) use and coloration. In Texas, juvenile grasshoppers feed almost exclusively on one of two host plants...

compost is one of the strategies of house hold solid wastes management that is used to decrease the volume and weight of wastes, odor and leach ate dispersion, resource recycles and decreasing disposal expenses. in order to observe environmental regulations in the frame of adaptation development projects with environmental concerns, assessment of environmental impact of composting plants has be...
