The flux-pinning mechanism and activation energy of 10 wt % malic acid-doped MgB2 were investigated by measuring of the critical current density and resistivity as a function of magnetic field and temperature. A crossover field, Bsb, was observed from the single vortex to the small vortex bundle pinning regime. For the sintered sample, the temperature dependence of Bsb(T) at low temperature i...

Effects of spray washing carcasses with Lauric Acid (LA)-Potassium Hydroxide (KOH) on bacteria recovered from Whole-Carcass Rinsates (WCR) were examined. Carcass skin was inoculated with antibiotic resistant strains of Escherichia coli, Salmonella Typhimirum and Campylobacter coli. The first trial examined effects of washing carcasses with water, 0.25% LA-0.125% KOH, 0.50% LA-0.25% KOH, 1.00% L...

In the course of work in the analysis of blood, the authors have employed a number of reagents for the removal of the proteins before proceeding to the determination of other constituents. Two of these, picric acid (1) and nitric acid (2)) appeared to offer peculiar advantages in the subsequent determination of chlorides and other inorganic constituents. However, it was found that the amount of...

Washing produce with sanitizing solutions is an important step in reducing microbial populations during postharvest handling. Little information exists regarding the effects of washing solution flow conditions on the efficacy of pathogen reduction during washing. This study was undertaken to investigate the effects of washing conditions such as flow velocity, agitation rate, and contact time on...

Bioethanol production is an established biotechnological process. Margins are low which prevent a larger scale of bioethanol. As large part the cost due to feedstock, use value unsterile feedstocks fermented by microbial communities will enable more cost-competitive bioethanol production. To select for high yield ethanol producing communities, three selective conditions proposed: acid washing c...

The widespread use of silver nanoparticles (Ag-NPs) in commercial products, especially textiles, will likely result in an unknown spread of Ag into the environment. The quantification and characterization of the Ag released from nano-Ag-products is an important parameter needed to predict the effect of Ag-NPs on the environment. The aim of this study was to determine the amount and the form of ...

Commercial fungal amylase (diastase) has been immobilized through diazotization onto zirconia coated arylamine glass beads, affixed inside a plastic beaker. The immobilized enzyme retained 73.3% of the initial activity of free enzyme with a conjugation yield of 8 mg/g. Optimum pH of enzyme was decreased, while temperatures for maximum activity, energy of activation, time of incubation and Km fo...
