Effect of Inorganic Chromium Supplementation on the Intestinal Mucosa Development of Heat-Stressed Broilers
Published In: GJSFR Part: B: Chemistry Volume: 12 Issue: 5 One Hundred and fifty (150) 7 day-old broilers under conditions of heat stress were randomly assigned to 3 dietary treatments of 3 replicates each. There were 10 birds in each replicate. The 3 diets were: Diet 1 – Control diet (without Chromium supplementation); Diet 2 - 0.15mg/kg Chromium supplementation and Diet 3 - 0.25mg/kg Chromium supplementation. The inorganic Chr...

Synthesis and Spectral Characterization Of Thorium (IV) Complexes With 3-Substituted-4-Amino-5-Mercapto-1,2,4-Triazole Schiff Bases
Published In: GJSFR Part: B: Chemistry Volume: 12 Issue: 5 Thorium(IV) complexes have been synthesized by reacting Th(IV) nitrate with Schiff bases derived from 3-substituted-4-amino-5-mercapto-1,2,4-triazole and glyoxal/ biacetyl/ benzyl in ethanol. These complexes have been characterized on the basis of elemental analysis, molar conductance and spectral studies. Analytical and spectral data suggest structures in which Th(IV) is six coordinated...

Seasonal Variations of Tropospheric Ozone Concentrations
Published In: GJSFR Part: B: Chemistry Volume: 12 Issue: 5 This study shows strong seasonality of ground level ozone concentrations with spring (September and October) maximum and winter (May and June) minimum levels. The levels were observed in decreasing order per season as: spring>summer>autumn>winter. The Johannesburg ozone levels were much lower than Botsalano and Marikana levels. The monthly levels for the 2007 to 2008 period were determin...

Comparison of Adsorption of Dye onto Low-Cost Adsorbents
Published In: GJSFR Part: B: Chemistry Volume: 12 Issue: 4 The adsorption of methylene blue onto Mytilus Edulis shells and corn stalks was studied under various conditions such as concentration of adsorbate, adsorbent dosage and granulometry. Batch adsorption experiments were conducted and the result showed that the adsorption was dependent to granulometry and adsorbate concentration, but was partly dependent on the adsorbent dosage. It was rapi...
