conclusions the present study showed that heat stress had a negative effect on job satisfaction; also there were no significant effects on job stress and job performance. results the results showed that job satisfaction had a negative correlation with wbgt index (r = -0.42, p < 0.001) and hssi (r = -0.49, p < 0.001). also, there was no statistical correlation among occupational stress and job p...

in this study we analyze the effects of environmental performance on the generation of firm value from dow jones sustainability index europe. we use a sample of 122 firms from different sectors, except financial one, which belong to this index for the years 2007 through 2009. the expected results, taking into account our hypotheses, should show a positive relationship between the generation of ...

the performance of a γ-al 2 o 3 /n-decane nanofluid shell-and-tube heat exchanger in a biomass heating plant is analyzed to specify the optimum condition based on the maximum heat transfer rate and performance index for wide range of nanoparticle volume fraction (0–7%). compared with pure          n-decane, the obtained results in this research show that by using γ-al 2 o 3 /n-decane nanofluid ...

We evaluated the most common indices to compare their sensitivity and specificity to introduce the most sensitive and specific index. We systematically searched five international indexing databases up to Dec 2018. For each index, we measured the diagnostic odds ratio (DOR), as well as summary ROC (SROC) curve which was used to compare the performance of each index. Deeks̕ tests of all discrimin...
