In the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (AFC) (which the electrolyte has cooling role of system) has been considered. Proper control volumes of system with specific qualification have been chosen. Consequently, heat and mass transfer in control volumes have been assessed. Considerations on them and contributed models lead to approve a double tube heat...

Improvement of feed efficiency in dairy farming economically has a great importance. In this study, the genetic parameters of net energy efficiency and its relationships with milk yield, 3.2% fat corrected milk, body weight, gross income and income over feed costs were investigated, by the 2589 monthly records collected from the 723 lactating cows in the 3 herds. The different requirements of e...

In this study, a combination of micro gas turbine, absorption cooling, and organic rankine cycle is selected. The system is modeled applying the laws of thermodynamic, and based on this model, exergy and economic analyses are performed for each component of the system. Four design variables, namely compressor pressure ratio, turbine inlet temperature, turbine efficiency, and compressor efficien...

A stochastic cost equation was estimated for US dairy farms using national data from the production year 2000 to determine how farmers might reduce their cost of production. Cost of producing a unit of milk was estimated into separate frontier (efficient) and inefficiency components, with both components estimated as a function of management and causation variables. Variables were entered as im...

cost-effectiveness analysis (cea) can help countries attain and sustain universal health coverage (uhc), as long as it is context-specific and considered within deliberative processes at the country level. institutionalising robust deliberative processes requires significant time and resources, however, and countries often begin by demanding evidence (including local cea evidence as well as evi...
