Research ArticleOpen accessIn the keywordsDye Removal from Aqueous Solution by using Adsorption on Treated Sugarcane BagasseS. Saiful Azhar, A. Ghaniey Liew, D. Suhardy et al.The use of cheap and ecofriendly adsorbents has been studied as an alternative substitution of activated carbon for the removal dyes from wastewater. Adsorbents prepared from sugarcane baggase-an agro industries waste was successfully used to remove the methyl red from an aqueous solution in a batch reactor. This study investigates the potential use of sugarcane baggase, pretreated with formaldehyde (PCSB) … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 9,345 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCOLORIMETRIC DETERMINATION OF CEFQUINOME SULPHATE IN BULK AND DOSAGE FORM USING AMMONIUM MOLYBDATEShaza Wageialla Shantier, Elrasheed Ahmed GadkariemThis study was designed to develop two colorimetric methods for the determination of Cefquinome Sulphate (CS) in bulk and dosage forms using two different concentrations of molybdenum solution. The developed methods were based on the oxidation of CS with 2% ammonium molybdate, in the presence of sulphuric acid, producing a green colored product with λmax at 409 nm (Method I) … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 20 Dec 2013 · 7,051 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of a Mixture of Thermophilic Enzymes Produced by the Fungus Thermoascus aurantiacus to Enhance the Enzymatic Hydrolysis of the Sugarcane Bagasse CelluloseJ. R. Monte, W. Carvalho, A. M. F. MilagresProblem statement: The production of hydrolytic enzymes by T. aurantiacus has been performed under solid-state fermentations using lignocellulosic materials. The influences of the inoculum size and of the fermentation medium on the production of hemicellulases and cellulases were studied. Filtrates from the cultures were used to hydrolyze a pulp of sugarcane bagasse and the produced enzymes were shown to be … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 13 Dec 2010 · 9,212 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBuffering Capacity of Fast-Growing Species and Curing Time of UF Resin Modified With Zinc Borate and Monoammonium PhosphateIzran Kamal, Koh Mok Poh, Tan Yu Eng et al.Problem statement: Occupying a suitable hot pressing time for particleboard fabrication seems very tricky for manufacturers of the wood-based panel. Longer or shorter pressing times can affect physical and mechanical properties of the produced particleboards and that is why extra care should be given on this matter. Longer pressing time can cause resin in a particleboard to over-cure whereas shorter … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,777 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTemperature Optimization for Bioethanol Production from Corn Cobs Using Mixed Yeast StrainsClarence S. Yah, Sunny E. Iyuke, Emmanuel I. Unuabonah et al.Problem statement: Dilute sulphuric acid and enzymatic hydrolysis methods were used for sugar extraction. Xylose and glucose sugars were obtained from corn cobs. Approach: Acid hydrolysis of corn cobs gave higher amount of sugars than enzymatic hydrolysis. Results: The results showed that optimal temperature and time for sugar fermentation were approximately 25°C and 50 h by two yeast strains (S. … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 30 Jun 2010 · 9,339 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpectrofluorimetric, Atomic Absorption Spectrometric and Spectrophotometric Determination of Some FluoroquinolonesHesham SalemSimple, accurate, sensitive and selective spectrofluorimetric, atomic absorption spectrometric and spectrophotometric methods are described for the quantitative determination of ten fluoroquinolones (amifloxacin, ciprofloxacin hydrochloride, difloxacin hydrochloride, enoxacin, enrofloxacin, lomefloxacin hydrochloride, levofloxacin, norfloxacin, ofloxacin and pefloxacin mesylate). The first method was a spectrofluorimetric method in which samples of the studied drugs in 0.1 N H2SO4 showed native fluorescence at 450 nm … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,317 accessesView PDF Cite
