Rubber has been grown for several decades in Africa, notably in Ivory Coast. Although the yields obtained with selected clones are good, some problems with adaptation to edaphic and climatic conditions have yet to be solved. Of these problems, tree breakage due to violent winds during frequent storms is a major handicap. Some clones are more resistant to wind damage. However, this resistance tr...

in this article the transient heat transfer in rubber parts has been studied. this study is usefull for estimation of the minimum curing time of the rubber parts and thereby to ensure the quality of the rubber. also is the temperature distribution during the rubber curing is well know, then the curing time could accurately be estimated, which will lead to a better curing process. in this regard...

BACKGROUND Urinary 1-hydroxypyrene (1-OHP) was selected as a biomarker of polycyclic aromatic hydrocarbons (PAHs) to explore the accumulation level in the bodies of workers at rubber smoke sheet factories in southern Thailand. METHODS Spot urine samples were taken from four groups of workers from June 2006 to November 2007. The nonexposure or control groups included habitual cigarette smokers...

A wide variety of materials used in manufactured items are subject to microbiological deterioration. Those materials which are of chief concern include textiles and cordage, paper, leather, paints, plastics and plasticizers, rubber, waxes, and wood. The organisms responsible for microbiological deterioration, their mode of attack, and effects on materials, have been reviewed (Greathouse et al.,...
