the blending of nr and br rubber blend with n330 carbon black is studied on curing behavior and the physico-mechanical properties of a sbr rubber based tire tread compound containing n234 carbon black. the effect of sulphur and accelerator contents on different properties of rubber compound is also tested with a wide range of curing agents. partial substitution of sbr with nr shows significant ...

economic growth and development of market, stock exchange and related variables are among components which influence on business, economic activities and management of society. financial repression is among economic variables greatly influencing on financial market specifically capital market and economic growth and development; so that, this concept caused to publish financial growth and devel...

this study was conducted with different levels (0, 0.25, 0.5,1,2 g) of zingiber officinale powder per 100 g of common carp commercial diet. feed was offered for 8 weeks by the post pelleting liquid spraying method. results showed that there were significant differences in all growth parameters and body composition except in survival rate, gain weight percent (gw%) ,sgr and nfe between treatment...

abstract an experiment was conducted to study growth analysis and evaluation of change in simple non- structural carbohydrates (sucrose, glucose and fructose) during bulb formation of ghermez azarshahr , zargan, safid naishaboor and safid qom cultivars in randomized complete block design containing three replications. seeds were sown in nursery in early february and seedlings were transplanted ...

Mungbean (Vigna radiata (L.) Wilczek) or green gram as a dryland grain legume is exposed to varied timings and severity of drought stress, resulting in variability in photoassimilate production. In order to evaluate some physiological responses in one mungbean cultivar to timing and severity of drought stress, a 3-replicate RCBD (randomized complete block design) field experiment was carried ou...

Growth parameters such as leaf area (LA), total dry mass (TDM) production, crop growth rate (CGR), relative growth rate (RGR), and net assimilation rate (NAR) were compared in six varieties of mungbean under subtropical condition (24°8' N 90°0' E) to identify limiting growth characters for the efficient application of physiology breeding for higher yields. Results revealed that a relatively sma...
