The cleaning, washing, drying, and powdering of surgical rubber gloves is a disagreeable task requiring a good deal of manipulation, and consequently a relatively large expenditure of man hours. It is necessary, too, when gloves are used in laboratories working with pathogens that a preliminary decontamination be given to prevent the gloves from becoming a source of infection. Graham (1957) des...

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...

OBJECTIVES Surface attributes of a restoration play an important role in adherence of plaque bacteria. Prophylaxis methods may be involved in modification of or damaging the restoration surface. The aim of the present study was to evaluate the effect of two prophylaxis methods on adherence of Streptococcus mutans to the surface of two restorative materials. STUDY DESIGN A total of 60 specimen...

Compact Fluorescent Lamps (CFLs) are composed of glass, plastic, non-ferrous metal, ferrous metal, paper, plastic, rubber, and so on. In order to separate glass and plastic among CFLs components, air separation unit is applied using the difference in specific gravity. Since specific gravities of glass, plastic, non-ferrous metals, rubber, etc. were widely spread, it can be separated by the diff...

At the International Congress of Industrial Medicine in Naples (Noro and Uotila, 1954), it was stated that " the inhalation of zinc stearate dust is known as a cause of pneumonia in children, but its effects in the working environment are not so well known. The authors describe the fatal case of a worker employed for 29 years in a rubber plant. Clinical examination and necropsy showed diffuse f...

The gel to carbonate precipitate route has been used for the synthesis of Ni1-xZnxFe2O4 (x = 0, 0.25, 0.5 and 0.75) bulk inverse spinel ferrite powder samples. The optimal zinc (50%) substitution has shown the maximum saturation magnetic moment and resulted into the maximum magnetic loss tangent (tanδm) > -1.2 over the entire 2-10 GHz frequency range with an optimum value ~-1.75 at 6 GHz. Ni0.5...

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...

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...

In order to study the effect of UV aging on asphalt performance, four-component test, dynamic shear rheology and flexural creep stiffness test were combined with molecular dynamics simulation matrix rubber powder/styrene-butadiene rubber/polymerization. The properties phosphoric acid/epoxy resin modified before after analyzed, mechanism was discussed. Research shows that has better high low tem...
