background: in addition to individual problems and conditions, low back pain reduces working capacity, resulting in the waste of time and absence from the work, and increases healthcare costs and economic losses. this study aimed to determine the prevalence rate of low back pain and its relationship to demographic factors, body mass index, and education in ergonomic principles in rural men.   m...

In breeding programs determination of gene effects and general and specific combining ability for screening of test crosses is necessary. In order to estimate the genetic variance components and the general and specific combining ability of sweet corn lines, an experiment was conducted using 8 sweet corn S6 inbred lines (including 4 maternal and 4 paternal lines) by line × tester mating design ...

a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

a 7×7 complete diallel cross experiment was performed to study the genetic relationships of grain yield and some agronomic traits in rice. analysis of variance showed significant differences among genotypes for all traits. results of correlation analysis showed that rice grain yield was positively and significantly correlated with by (rp = 0.81, rg =0.55), hi (rp =0.35, rg =0.79), np (rp = 0.80...

one of the most effective ways to deal with drought stress and increase water use efficiency is the development of drought-tolerant varieties which display less reduction in yield per unit water reduction. therefore, the breeding of diploid pollinators was considered as an essential measure for producing drought-tolerant hybrids. in this study, from 4 diploid pollinator populations, 45 half-sib...

In order to decrease effect of genotype × environment interaction, yield and yield stability should be considered simultaneously. In present study, 24 bread wheat genotypes were evaluated in Gorgan and Gonbad agricultural stations in 2012-13 and 2013-14 cropping seasons. Experiments were conducted based on complete block designs with three replications at 6th December and February. Combined ana...
