in this research work with the aid of tagouchi experimental design and rawing of interaction curves with minitab software, the best rotor speed and dump temperature of mixing for physico-mechanical and rheological properties of the rubber compound with three mixing steps was obtained. moreover by plotting the mean curves in excel worksheet, the dependency of properties on rotor speed, dump temp...

Standard postharvest unit operations that rely on copious water contact, such as fruit unloading and washing, approach the criteria for a true critical control point in fresh tomato production. Performance data for approved sanitizers that reflect commercial systems are needed to set standards for audit compliance. This study was conducted to evaluate the efficacy of chlorine dioxide (ClO(2)) ...

Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...

dUTPase (deoxyuridine 5'-triphosphate nucleotide hydrolase) is an enzyme responsible for maintaining low levels of intracellular dUTP and thus prevents uracil incorporation into DNA by DNA polymerases during replication and repair processes. The thermodynamics of binding for both dUTP and dUMP (deoxyuridine 5'-monophosphate) to the D80A mutant form of Trypanosoma cruzi dUTPase have been investi...

This article describes an rf ion source with a back-streaming electron dump. A quartz tube, brazed to a metal plug at one end, is fused in the center of a flat quartz plate. rf power (at 13.6 MHz) is coupled to generate hydrogen plasma using a planar external antenna bonded to the window. Bonding the water-cooled rf antenna to the quartz window significantly lowers its temperature. The water-co...

The Overburden of waste and uneconomic mineralized rock is required to be removed to mine the useful mineral resource in a surface mining operation. In this process a dump is formed by casting the waste material and dumping it in nearby area. The dump so formed is known as mine waste dump. Waste dump may be classified as internal and external dump. External dump is created outside the pit where...

Dump consisting of 9500 tons of rich-in-pyrite mining wastes located in the uranium deposit Curilo, Western Bulgaria, was, after rainfall, an intensive source of acid drainage waters. These waters had a pH in the range of about 1.7-4.5 and contained radionuclides (uranium, radium), heavy metals (copper, zinc, cadmium, lead, nickel, cobalt, iron, and manganese), arsenic and sulphates in concentr...

It was found that there are two kinds of pyrimidine nucleoside, monophosphokinase deoxythymidine 5'-monophosphate-deoxyuridine 5'-monophosphate (dTMP-dUMP) kinase and cytidine 5'-monophosphate-deoxycytidine 5'-monophosphate-uridine 5'-monophosphate-doexyuridine 5'-monophosphate (CMP-dCMP-UMP-dUMP) kinase, and their molecular weights were calculated to be 46,000 and 26,000, respectively, by gel ...

Antidumping reform is critical to a successful completion of the Doha Round of multilateral trade negotiations and US willingness to engage in such reform is key to this effort. This paper assesses prospects for such reform by analyzing US implementation of Uruguay Round antidumping reform commitments. The results strongly suggest that the US has lived up to only the letter but not the spirit o...
