Research ArticleOpen accessIn the abstractOptical Properties and Sugar Content Determination of Commercial Carbonated Drinks using Surface Plasmon ResonanceW. Y.W. Yusmawati, H. P. Chuah, M. Y.W. MahmoodIn this study, an optical sensor based on Kretschmann SPR technique was used to detect the sugar content in commercial carbonated drinks. Three samples of carbonated drinks labeled as "Coke", "100 Plus" and "F&N Orange" have been chosen for angle scan SPR measurements. All the measurements were carried out at room temperature using He-Ne laser beam (632.8nm, 5mW) as a … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2007 · 8,784 accessesView PDFCite
Research ArticleOpen accessIn the abstractDIELECTRIC CHARACTERIZATION OF LIQUID CONTAINING LOW ALCOHOLIC CONTENT FOR POTENTIAL HALAL AUTHENTICATION IN THE 0.5-50 GHz RANGEZurina Zainal Abidin, Fatin Nordalila Omar, Pavithiran Yogarajah et al.A potential method for detection and discrimination of alcoholic containing drinks for halal authentication using dielectric properties has been investigated. Behaviors of several pure alcohols, alcohol solution in water and also liquids with alcoholic contents were studied for verification purpose. Dielectric constant and dielectric loss factor for low concentration of ethanol solutions were measured over the microwave frequency from 0.5 … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 24 Apr 2014 · 7,671 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characterization of Bacillus thuringiensis from soil habitat of Auky Island, Padaido District in Biak Numfor Regency and Its Toxicity against Mosquito Larva of Anopheles spLantang Daniel, Rampa Ester, Lunga NellyBacillus thuringiensis (Bt) is bacteria that produce protein crystals as an insecticidal against various vector diseases in plants and animals including humans. The purpose of this research is to discover the local isolate toxicity of B. thuringiensis from Auky Island Padaido District in Biak Numfor Regency against mosquito larva Anopheles sp., as well as to discover the local isolate of … …American Journal of Infectious Diseases, Vol. 14, Issue 2 · 4 Sep 2018 · 9,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Lead in Human Teeth by Hydride Generation Atomic Absorption SpectrometryHassan T. AbdulsahibProblem statement: The determination of lead in human teeth at concentration levels of μg/ml is proposed using Hydride Generation Atomic Absorption Spectrometry (HG-AAS). To do this, 2% (wv) lanthanum chloride solution was employed as matrix modifying reagent to increase sensitivity and remove matrix interferences. Approach: About 100 μL of sample and 100 μL of 3.0% (m/v) NaBH4 are simultaneously injected … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 31 Oct 2011 · 7,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractResidential Exposure of Environment Toxic Substance Outcome during Menstrual CycleS. Alagendran, G Archunan, M. P. Jonathan et al.Problem statement: It was intended to diagnose and treat the disorders of female reproductive system where they are exposed to environmentally toxic pesticides and estrogenic compounds like bisphenol A which are the main reason for the infertility problems. Approach: Human saliva contains arrays of proteins that have distinct biological functions. Results: Salivary hormones concentrations of luteinising hormone, follicle stimulating hormone, … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 6,873 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Studies of the Determination of Divalent Cadmium, Lead and Copper in the Boiling Medicinal Herbs by Stripping Voltammetry and by Atomic Absorption SpectrometryAhmed Hassan, Jamal A. MayoufCadmium, lead and copper were determined in ten Libyian boiling medicinal herbs samples by differential pulse anodic stripping voltammetry as well as by atomic absorption spectrometry. Voltammetric method was done at Hanging Mercury Dropping Electrode (HMDE) in Briton-Robinson buffer solution of pH ~2.1 at 25± 0.1°C. The sample preparation was carried out by boiling 2.0g of a finely pulverized plant … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiocontrol of Botrytis allii Munn the Causal Agent of Neck Rot, the Post Harvest Disease in Onion, by use of a New Iranian Isolate of StreptomycesM. Jorjandi, G.H. Shahidi Bonjar, A. Baghizadeh et al.Problem statement: Soil actinomycetes particularly Streptomyces spp. have showed antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. Onion neck rot or gray mold caused by Botrytis allii have imposed economic post harvest damages to onion bulbs and decreased its storage durability and market value. Approach: To investigate for … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractModels for Mixed Ensemble of Hydrometeors and their Use in Calculating the Total Random Cross Section of a Resolution Volume Filled by Random ScatterersAyman Al-Lawama, Salaheddin Malkawi, Abdullah Al-Odienat, Felix YanovskyFlight safety is of a major concern in aircrafts since the beginning of air traffic. One of the problems threatening the safety is the in-flight icing of the aircraft. This research deals with a problem arises in the context of weather aviation maintenance. Methods of aircraft icing are based on the difference in behavior of the polarization of radar signal … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Metoprolol and Felodipine in Binary Mixture Using Chemometric-Assisted Spectrophotometric and High-Performance Liquid Chromatographic-UV MethodsHesham Salem, Ola M. AbdallahFour methods were developed for simultaneous determination of metoprolol and felodipine without previous separation. In the first method both drugs were determined using first derivative UV spectrophotometry, with zero crossing measurement at 222 and 235 nm for metoprolol and felodipine, respectively. The second method depends on first derivative of the ratios spectra by measurements of the amplitudes at 250.1 nm … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 8,025 accessesView PDFCite
