Untapped pine needles with high potential for energy generation in the hilly area are not only a waste of resource but also increase the chance of environmental hazards as forest fires and GHG emission. This study is conducted to propose a new hybrid system (PV/Wind/Biomass) using abundant pine needle resource as a replacement of existing roof-mounted PV/wind hybrid system and analyse the feasi...

the objectives of this research were to investigate influences of energy inputs and energy forms on output levels and evaluation of co2 emissions for hazelnut production in guilan province of iran. moreover, the sensitivity analysis was done by marginal physical productivity (mpp) method for energy inputs and energy using linear regression. initial data were collected from 120 orchardists in se...

considerable consequence of households’ consumption expenditure changes is on energy using in agricultural sector and in other economical sectors. the main objective of this paper was to study of consequences increasing rural and urban households expenditures on changing of energy using in agricultural sector and on producing of environmental pollutants in khorasan razavi province. for this pur...

the bulk of our knowledge on immunosuppression in malnutrition comes from the experiments done on cell-mediated immunity. however, malnutrition-induced modifications of humoral immunity have been less understood. the objective of this study was to determine the effects of acute protein-energy malnutrition on serum levels of immunoglobulins and their subclasses in murine models. male and female ...

during the 1960s, the relatively new approaches like environmental warfare and intentional environmental deterioration came in to the global security and strategic literature. till now, through different conventional and unconventional wars, the governments have imposed intentional and unintentional adverse effects on the environment some of which are lasting for decades. the application of wea...

the canola drying process was investigated using three laboratory scale dryers connected to a computer which continuously recorded the drying processes of each unit. a completely randomized design (crd) with three replications was used for the statistical analysis. the effect of temperature (40°, 50°, 60°c) and air velocity (1, 2 m/s) on the drying kinetics of a monolayer were studied. the effe...

piezoelectric nanobeams having circular, rectangular and hexagonal cross-sections are synthesized and used in various nano structures; however, piezoelectric nanobeams with hexagonal cross-sections have not been studied in detail. in particular, the physical mechanisms of the surface effect and the role of surface stress, surface elasticity and surface piezoelectricity have not been discussed t...

in order to perform each component of agricultural practices, its plan should be rationalized economically and technically. in a study for recognition patterns of energy inputs and outputs in saffron fields of southern khorasan, iran, during a five years exploitation period, two questionnaires were prepared, one for the first cultivation year, and another for crop management and harvest during ...
