the financial losses, absolute and net economic values (evs) for direct (dcd) and maternal calving difficulty (mcd) were estimated using a bioeconomic model and taking into account the categorical nature of the trait. the effects of dystocia on other traits were estimated. but because of low reliability they were not considered for calculations in the base situation. in the base situation, the ...
the aim followed in the present study was to investigate the economic aspects of , and to derive economic weights (ews) for mature body weight (mbw) as well as for age at first calving (afc) in holstein dairy cattle of iran. economic values (evs) for traits were estimated using trait-by-trait bio-economic models. absolute evs were rls -16400 and -17900 per cow per year for mbw and afc, respecti...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
in order to evaluate the economic performance of rehabilitation centers for addicted persons, the welfare organization asked all its centers to send the expense table of esfand 79-80 and fill out the information wanted there. the economic analysis is based upon this information. also, each center is provided with a questionnaire to estimate monthly expenses. according to the preventive scale of...
abstract governing was disorganized for years, when mongols attached to iran and it caused to clearing way for interference of mongols princes. dispatching of holaku to the west culminated in establishing iilkhanan government. holakus activities in destruction of abbaasis government and activities which shows his staying in iran, made force oulus juji to comparison against iilkhanis gover...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Accurate open-circuit voltage (OCV) is crucial for state of charge (SoC) estimation lithium-ion batteries and, hence has become a key factor to ensure the safety and reliability electric vehicles (EVs). In engineering, incremental OCV (IO) testing been widely used calibrating. Based on this, commonly simplified by averaging discharging charging OCVs, which essentially ignores influence major hy...
Based on the characteristics of electric vehicles (EVs), this paper establishes the load models of EVs under the autonomous charging mode and the coordinated charging and discharging mode. Integrating the EVs into a microgrid system which includes wind turbines (WTs), photovoltaic arrays (PVs), diesel engines (DEs), fuel cells (FCs) and a storage battery (BS), this paper establishes multi-objec...
UNLABELLED RLSOBJECTIVES: To evaluate the humanistic and economic burden of a restless legs syndrome (RLS) diagnosis with regard to health-related quality of life, work productivity loss, healthcare resource use, and direct and indirect costs. STUDY DESIGN Self-reported data came from the 2012 National Health and Wellness Survey (NHWS), a large, annual, nationally representative cross-section...
