in recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. the hybrid system presented in this article produced power with sofc and stirling engine. the purpose is to analyze a 50 kw solid oxide fuel cell that could produce enough thermal energy for a 10 kw stirling engine working in the hybrid s...

the aims of this study were to investigate the energy flow and its modeling in shablon cultivar of plum production in golestan province of iran. data were collected through questionnaires and also interviews with producers. cobb-douglass model and sensitivity analysis were used to determine the effects of energy inputs on plum yield. the results revealed that the total energy inputs and energy ...

an interactive application, modelface, was presented for modeller software based on windows platform. the application is able to run all steps of homology modeling including pdb to fasta generation, running clustal, model building and loop refinement. other modules of modeler including energy calculation, energy minimization and the ability to make single point mutations in the pdb structures a...

in this work the kinetic data demanded for kinetic modeling were obtained in temperatures 350, 400, 450 and 500 oc by conducting experimentations on a fe-cr nanocatalyst prepared from a novel method and a commercial fe-cr-cu one. the collected data were subjected to kinetic modeling by using two models derived from redox and associative mechanisms as well as an empirical one. the coefficients o...

Smart meters that allow information to flow between users and utility service providers are expected foster intelligent energy consumption. Previous studies focusing on demand-side management have been predominantly restricted factors utilities can manage manipulate, but ignored specific residential characteristics. They also often presume households consume similar amounts of electricity. To f...

the first motive for the determination and evaluation of an energy productionsystem is the need to change. such system is dynamic in nature and is influenced bymany factors such as age and physiological status of individual sheep or goat, quantityand quality of available feed and environment including the management systems.traditional pastoral resource assessments do not always account for the...
