in this study, 32 multiparous non lactating holstein cows were used to investigate the effects of chromium-l-methionine (cr-met) supplementation and dietary energy source on production and nutrient digestibility during the periparturient period. cows were fed a total mixed ration from 28 days before anticipated calving through 28 days after calving. the study was designed as a randomized comple...

This article presents a perspective of the several modern alternative energy generation technologies. Moreover, authors facilitate case study application an emerging blockchain (EBC) technology and Published Energy Sources (PES). A methodical analysis utilizes EBC input parameters as follows: power such multi-energy complementarity, storage, smart grid that has meter and/or control within syste...

In this paper, a new method to review the role of wind units as an energy-producer in the scheduling problem of unit commitment is presented. Today, renewable energy sources due to lack of environmental pollution, absence of dependence on fossil fuels, and consequently a very low marginal cost, have been receiving considerable attention in power system. But these sources are associated with unc...

Today we are witnessing a global energy crisis due to huge energy demands and limited resources. Non-renewable energy sources are depleting and renewable energy sources are not properly utilized. There is an immediate need for search of alternate routes for energy generation. Microbial fuel cell (MFC) technology, which uses microorganisms to transform chemical energy of organic compounds into e...

E nergy consumption has increased significantly in Iran during the recent decades. In this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. The input-output tables of Iran for the years 1988 and 2001 have been employed as the database of the model. The innovation of this research allows the researchers to stud...
