the experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. a total of 150 day-old commercial broiler (cobb-500) was reared for a period of 35 days. there were five treatments including t0 (without rubber seed meal), t1 (10% rubber seed meal), t2 (20% rubber seed meal), and t3 (30% rubber seed meal) and t4 (4...

This research was conducted in the west forest of Guilan, northern Iran. Data from various harvesting methods for 20 years were collected. Results showed that, productivity rate of round wood, pulp wood and fuel wood has had an upward trend, while rate of traditional products (lumber, sawn wood, charcoal, etc.) has had a downward trend. Production cost has been investigated in this research. Th...

As the senile phase due and causes depeleting latex productivity, rubberwood stands can still be claimed as carbon sequestration under REDD + Scheme. This is also to maintain vegetation cover in protected forests, beside for fostering social forestry (HKm) sustainability well. Nowadays role of genetic environment factors on production have widely revealed by some researchers, but lack wood espe...

Non-ferrous material frequently slipped failure, hard clamp surface press slip occurs, and non-metal lacks a rigidity hold for the clamp, resulting in or break before limit strength. So as efforts to prevent this problem are carried out from additional grips reduce occurrence of slips obtain an increased testing accuracy. Additional grip designs created using sizes specified by ASTM D638. recei...

In the rubber industry, plasticizers for rubber compounds mainly consist of petroleum derivatives. Consequently, the rubber industry is in constant competition with many petroleum consumers. This competition places an economic strain on rubber companies such as HEXPOL RUBBER COMPOUNDING L.L.C. In order to alleviate this strain, natural oil alternatives to petroleum plasticizers are of novel res...

Recycling waste tire rubber by incorporating it into concrete has become the preferred solution to dispose of waste tires. In this study, the effect of the volume content of crumb rubber and pretreatment methods on the performances of concrete was evaluated. Firstly, the fine aggregate and mixture were partly replaced by crumb rubber to produce crumb rubber concrete. Secondly, the mechanical an...
