The objectives of this research were to study transfer and control of Escherichia coli O157:H7 during simultaneous washing of inoculated and uninoculated lettuce pieces and to determine the efficacy of antimicrobial agents (peroxyacetic acid, mixed peracid, and sodium hypochlorite) on reducing the transfer of E. coli O157:H7 through processing water with or without organic load. Lettuce leaf pi...

BACKGROUND The common causes of textile dermatitis are formaldehyde resins and disperse dyes. There are various methods to detect the presence of formaldehyde in clothing. AIM To detect the presence of formaldehyde in various types of textiles by the chromotropic acid method and to assess the effect of washing on the formaldehyde content. METHODS Twenty randomly selected textiles from a loc...

For further resource utilization of solid waste steel slag and the reduction in biodiesel production costs, this study used as a carrier to synthesize CaO-CeO2/slag base catalyst for effective transesterification palm oil into fatty acid methyl esters (FAMEs). The synthesis involved two-step impregnation with nitrate calcium cerium thermal activation at 800 °C 180 min. Then, catalysts’ textural...

In recent years, biodegradable and alternative biodiesel has attracted increased attention worldwide. Producing biodiesel from biomass involves critical separation and purification technology. Conventional technologies such as gravitational settling, decantation, filtration, water washing, acid washing, organic solvent washing and absorbent applications are inefficient, less cost effective and ...

This study devised a protocol for the manufacture of commercial quantities of chicken liver pâté that reliably destroyed campylobacters. A literature search identified 40 pâté manufacture recipes. Recipes stages with a potential to be antimicrobial were assembled to form a new protocol that included washing with organic acid, freeze-thaw and flambé in alcohol. Naturally-contaminated, high-risk ...

Treatment of sheep erythrocytes with suitable concentrations of tannic acid render them capable of adsorbing certain protein molecules from solution in saline. Red cells which have adsorbed proteins in this way are agglutinated after washing by the homologous antiprotein sera, even by high dilutions. Through hemagglutination sera can be titrated for antibodies against antigens adsorbed on the c...

The purpose of this study is to propose the flotation procedure seafloor massive sulfide (SMS) ores separate chalcopyrite and galena as froth sphalerite, pyrite, other gangue minerals tailings, which currently facing difficulties due presence water-soluble compounds. obtained SMS ore sample contains CuFeS2, ZnS, FeS2, SiO2, BaSO4 in addition PbS PbSO4 Pb minerals. Soluble compounds releasing Pb...
