this study considered the production economics of coffee in pakuwa village development committee of parbat district, nepal. household survey was done in june 2014. data collection was done using semi-structured pre-tested questionnaire administered on 40 coffee producers selected randomly. gross margin analysis, profitability index and the benefit-cost ratio was used to analyze the production e...
in some data envelopment analysis (dea) applications, some inputs of dmus have negative values with positive cost. this paper generalizes the global cost malmquist productivity index to compare the productivity of di erent dmus with negative inputs in any two periods of times under variable returns to scale (vrs) technology, and then the generalized index is decomposed to several components. th...
this paper presents a case study to determine the efficiency of the currently used heat stress indices in correlation with wet bulb globe temperature (wbgt) as a permissible index at a foundry plant and to evaluate the extent of the physiological responses such as heart rate and body temperature in correlation with heat stress indices. the field consisted of a foundry plant where a shift work w...
A field experiment was conducted to assess the effect of real time nitrogen management through leaf colour chart and chlorophyll meter in wheat. The experimental results revealed that Leaf color ≤5 based application recorded significantly higher growth, yield attributes, which statistically at par with ≤ 4, sufficiency index ≤3. However, recommended highest agro physiological efficiency. Suffic...
Physiological Cost Index (PCI) has been proposed to assess gait demand. The purpose of the study was to establish whether PCI is a valid indicator in subacute stroke patients of energy cost of walking in different walking conditions, that is, over ground and on the Gait Trainer (GT) with body weight support (BWS). The study tested if correlations exist between PCI and ECW, indicating validity o...
Introduction: Determining methods for assessing heat stress in different work environments is one of the major challenges for researchers in this field. The purpose of this study was to validate WBGT index and heat pressure assessment (HPA) by some physiological responses in Iranian South Oil Company. Material and Methods: This descriptive-analytical study was carried out on 154 employees of K...
