In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...

the present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (dap) in the mineral mixt...

sustainable development of the production in every region requires consideration of energy flow in the production system, moreover, investigating the production system inputs from environmental management point of view is of high importance. in this study energy use and greenhouse gas emissions is investigated. data were collected through interviews with 75 tea farmers and comparing the results...

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 ...

abstract intensive and inefficient use of energy leads to degradation of natural resources and environmental problems. this study evaluated the relationship between the energy of consumed inputs and yield of tomato, cucumber and melon using the cobb–douglas production function. the data were collected from 90 farmers in firoozabad using a questionnaire. the farmers were chosen by simple random ...

the study was carried out on 120 crossbred holstein × shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. the farms were located in the peri-urban and ur...

The x-ray emission with the single crystal of lithium niobate (LiNbO3) or lithium tantalite (LiTaO3) by thermal changes in a vacuum system is closely concerned with the electronic state of each crystal. Therefore, lithium Kedge x-ray absorption near edge structures (XANES) spectra of these materials were measured in the region from 50 eV to 90 eV by means of total electron yield method (T.E.Y.)...
