Workers in the rubber industry are exposed to pulmonary health hazards. The main purpose of this study was to assess the combined effect of cigarette smoking and occupational exposures on lung function. The exposed group consisted of tire manufacturing workers in production units and the non-exposed group included executives from the same factory. The researchers calculated the synergy index (S...

Occupational accidents and injuries present a serious social, medical and economical problem in Serbian industries in transition. The purpose of this study is to estimate the number and average annual rate of occupational accidents and traumatic injuries in Serbian industries in transition, between 1992 and 2003, and to estimate the effects of a preventive safety program in the rubber manufactu...

Biological monitoring of genotoxic hazard in the rubber industry was performed in 19 male workers and 20 age-matched controls in a local health unit in northern Italy. Peripheral blood lymphocytes were analyzed for the presence of DNA damage (single-cell microgel-electrophoresis, or comet assay) and for cytogenetic parameters (sister chromatid exchanges and micronuclei frequency, and proliferat...

There is a lot of ongoing active research all over the world looking for various applications used tyre rubber, to increase its utilisation rate. One common incorporate rubber into concrete as partial replacement conventional aggregates. However, due poor bonding performance with cement paste, in has been hindered date. A cost-effective and time-saving pre-treatment method great interest, espec...

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...

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...

BACKGROUND Diethylthiourea is widely used in the rubber industry, particularly in neoprene rubber, and may cause allergic contact dermatitis. However, as thiourea allergens are not part of the European baseline series, the diagnosis of allergic contact dermatitis caused by thiourea compounds depends on clinical suspicion and aimed testing. OBJECTIVES The aims of this study were to evaluate th...

In this paper, the physical behaviors of the interaction between a spark-generated bubble and a rubber beam are studied. Both numerical and experimental approaches are employed to investigate the bubble collapse near the rubber beam (which acts as a flexible boundary) and the corresponding large deformation of the beam. Good agreement between the numerical simulations and experimental observati...

The rubber-producing tree, Ficus elastica (the Indian rubber tree), requires the same substrates for rubber production as other rubber-producing plants, such as Hevea brasiliensis (the Brazilian or Para rubber tree), the major source of commercial natural rubber in the world, and Parthenium argentatum (guayule), a widely studied alternative for natural rubber production currently under commerci...
