In experiments on broiler chickens of the SGC “Smena” selection, it was found that partial replacement fish meal with an additive based a protein microbial origin, containing 68.3% crude protein, allows to provide live weight comparable control high poultry safety, due good digestibility and availability amino acids. A comprehensive assessment productivity broilers according index showed 50% co...

The fossil fuels consumption is rapidly growing due to increased water and electricity demands. An interconnected water-energy nexus is generally composed of thermal power plants, combined potable water and power (CWP) generation units, and desalination only processes. Hence, participation of hydro power plants in electricity generation facilities not only reduces the total fuel consumption of ...

this study focuses on the effect of social and cultural determinants on generation gap in tehranian families in 2011. the purpose of this study is to determine effective factors on generation gap in tehranian families, analytical and empirical patterns and be surveyed by related theories and effective factors. the research was prepared by questions including whether there is a relationship betw...

This paper proposes an effective multi-objective differential evolution algorithm (MDES) to solve a permutation flow shop scheduling problem (PFSSP) with modified Dejong's learning effect. The proposed algorithm combines the basic differential evolution (DE) with local search and borrows the selection operator from NSGA-II to improve the general performance.  First the problem is encoded with a...

Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
