Background and purpose: Dyes are one of the main pollutants in the various industrial wastewaters. Therefore, the aim of this study was to assess the biosorption of acid red 18 dyes from aqueous solutions by brown macroalgae biomass “Sargassum glaucescens.” Materials and Methods: This research was a lab study. S. glaucescens was used as an adsorbent to remove acid red 18. The effect...

Nickel oxide (NiO) nano-size powder is synthesized using nickel (II) acetate tetrahydrate, sodium lauryl sulfate (SLS) and ammonia as precursors. Applied surfactant is anionic surfactant. The sample was characterized by FT-IR, X-ray diffraction (XRD), scanning electron microscopy (SEM). The results obtained confirm the presence of nickel oxide nano-powders produced during chemical precipitation...

Dyes are one of the most important existing pollutants in textile industrial wastewater. These compounds are often toxic, carcinogenic, and mutagenic to living organisms, chemically and photochemically stable, and non-biodegradable. Acid red 18 is one of the azo dyes that are currently used in the textile industries. Photocatalytic degradation offers a great potential as an advanced oxidation p...

Dietary Polyunsaturated Fatty Acids Modify Plasma Lipids and Red Blood Cell Membrane Composition but Do Not Induce ∆6 Desaturase Mediated Conversions in the Domestic Feline. (May 2008) Melena Kathleen McClure, B.S., The University of Texas at Austin Chair of Advisory Committee: Dr. John E. Bauer This study explored the effects of dietary unsaturated fatty acids on feline lipid metabolism. It wa...

Standard methods for the methyl red (MR) test are not practical for routine use in clinical laboratories because of the necessarily prolonged incubation period. When read after overnight incubation, the usual MR test is often equivocal or falsely positive. The present study demonstrates the importance of standardizing the total volume of broth, the size of the vessel in which the cultures are i...

The effects of dietary 18:3n 3 on the fatty acid composition of plasma, red blood cells, aorta, platelets, plasma cholesterol, triglycerides, and platelet response to collagen-induced aggregation in swine was investigated. Pigs (n ) 25) were fed diets containing 18:3n 3 at 0% (control), 1.5% (LNA1), 2.5% (LNA2), and 3.6% (LNA3). Dietary 18:3n 3 resulted in a significant (P < 0.05) enrichment of...
