in this paper, an adaptive-network-based fuzzy inference system (anfis) is used for forecasting of natural gas consumption. it is clear that natural gas consumption prediction for future, surly can help statesmen to decide more certain. there are many variables which effect on gas consumption but two variables that named gross domestic product (gdp) and population, are selected as two input var...

natural disasters result in numerous economic, social, psychological and cultural consequences. of them, psychological consequences of disasters will affect the lives of people long after the critical conditions finish. thus, concerning the importance of psychological support in disasters, this study has identified problems and weaknesses in dealing with the psychological effects of the disaste...

environmental protection is not at odds with the proper use of all the offered possibilities.along these lines, the touristic products available to the consumer has increased exponentially over the lastfew years which has made it possible to convert territorial and patrimonial resources into significant elementsof recreational use put into value at service of the consumer. surveys on the recrea...

the use of agriculture residues as filler in composites is increasing due to their strength, abundance and low cost. soya stalks show promising renewable natural fiber. in polyethylene composites the physical and mechanical properties (flexural resistance, tensile, impacted absorbed energy, water uptake and thickness swelling) was examined at different composites. the results showed that, the m...

this study investigates the application of landscape ecology in planning and design of urban ecological systems. the ecological approach to landscape planning and the concepts of designing and implementing ecological systems have gained increasing attention in the last two decades. however, the ecological systems of urban environment need more research to consider built and natural patches and ...

the adoption of integrated pest management (ipm) strategy by farmers of bathinda cotton belt of punjab, india resulted in reduction of insecticidal applications. there was 3-4 times reduction in insecticidal applications in ipm villages (4.86-5.33) over the non-ipm villages (15.16-18.12). a general trend of reduced insecticidal applications of both conventional as well as new insecticides, in i...

recently, some natural products have been used in the fields as alternative to synthetic compounds, to minimize the negative impacts to the environment. this study aimed to verify the effects of neem-based bio-pesticide in causing acute toxicity for a fish and chronic toxicity for a microcrustacean. to this end, danio rerio and daphnia magna were exposed to various concentrations of a neem-base...

habrobracon hebetor say (hymenoptera: braconidae) as an ectoparasitoid of larval stage of lepidopterous pests is widely used in biological control programs. in the present research, the effect of field recommended doses of imidacloprid, indoxacarb and deltamethrin were studied on life table parameters of h. hebetor in pupal stage treatment. one hundred, two-day-old pupae were treated with 1 mic...

it has been revealed that the surface stress effect plays an important role in the mechanical behavior ofstructures (such as bending, buckling and vibration) when their dimensions are on the order ofnanometer. in addition, recent advances in nanotechnology have proposed several applications fornanoscale shells in different fields. hence, in the present article, within the framework of surfaceel...
