Research ArticleOpen accessIn the abstractSpecific Heat and Thermal Conductivity of Berberis Fruit (Berberis vulgaris)Mortaza Aghbashlo, Mohammad Hossein Kianmehr, Seyed Reza Hassan-BeygiBerberis fruit was known as a medicinal and ornamental plant in the world. It is used in medicine to cure the liver, neck and stomach cancer, blood purification and mouth scent. In order to design of equipments and facilities for the drying, preservation and processing of berberis, it is necessary to know about the specific heat and thermal conductivity. Therefore, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,982 accessesView PDFCite
Research ArticleOpen accessIn the abstractFunctional Link Artificial Neural Network for Classification Task in Data MiningB. B. Misra, S. DehuriIn solving classification task of data mining, the traditional algorithm such as multi-layer perceptron takes longer time to optimize the weight vectors. At the same time, the complexity of the network increases as the number of layers increases. In this study, we have used Functional Link Artificial Neural Networks (FLANN) for the task of classification. In contrast to multiple layer … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 60,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptical Properties and Kinetic Behavior of Chlorine in Pure Water and Swimming Pool Water using Surface Plasmon Resonance TechniqueW.Y.W. Yusmawati, W. Mahmood Mat YunusAn optical sensor based on surface plasmon resonance phenomenon for detection of chlorine in pure water and swimming pool water is presented. The measurement was carried out at room temperature using Kretschmann surface plasmon resonance technique. When the air medium outside the metal film is changed to chlorine solution, the resonance angle shifted to the higher value. The shift of … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractIR Laser Plasma Interaction with GlassRabia Qindeel, Noriah Bidin, Yaacob Mat DaudThe interaction of laser plasma with respect to glass surface is reported in this paper. A Q-switched Nd:YAG laser was used as ablation source. Glass material is utilized as target specimen. Aluminum plate is used as a rotating substrate. The dynamic expansion of the plasma was visualized by using CCD video camera and permanently recorded via image processing system. The … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,915 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
Research ArticleOpen accessIn the abstractAn Efficient Algorithm for Capacitated Multifacility Location ProblemsChansiri Singhtaun, Peerayuth CharnsethikulIn this paper, a squared-Euclidean distance multifacility location problem with inseparable demands under balanced transportation constraints is analyzed. Using calculus to project the problem onto the space of allocation variables, the problem becomes minimizing concave quadratic integer programming problem. The algorithm based on extreme point ranking method combining with logical techniques is developed. The numerical experiments are randomly generated to … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,441 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Error Correction Intuitive Approach in Quantum Communications ProtocolsAris Skander, Merabtine Nadjim, Malek BenslamaQuantum Error Correction will be necessary for preserving coherent states against noise and other unwanted interactions in quantum computation and communication. We develop a general theory of quantum error correction based on encoding states into larger Hilbert spaces subject to known interactions. We obtain necessary and sufficient conditions for the perfect recovery of an encoded state after its degradation by … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Profile of Some Heavy Metal Ions Adsorption Onto Biomaterial SurfacesMedhat A. ShakerThe adsorption of Co2+, Zn2+, Pb2+ and Hg2+ onto dried non-living biomass (NB) of different Pseudomonas strains has been investigated in detail. Maximum adsorption of these cations is achieved at optimum pH values from 3.5 to 4.5 to avoid hydrolysis, polymerization and precipitation of metal cations in the treatment solutions. The experimental data obtained at different temperatures were fitted to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,877 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Study of the Moving Boundary Problem During Melting Process in a Rectangular Cavity Heated from BelowY. Jellouli, R. Chouikh, A. Guizani, A. BelghithWe present an analysis of the melting process in Phase Change Materials (PCM) in a horizontal cavity heated from below, driven by the coupling of transient heat conduction in the solid phase and steady state laminar natural convection in the liquid phase with one of the boundaries of the solution domain that moves. We state the problem in the Cartesian … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Diloxanide Furoate and Metronidazole in Binary Mixture Using First Derivative of the Ratio-Spectra and High-Performance Liquid Chromatography-UV MethodsNora H. Al-ShaalanTwo methods are presented for simultaneous determination of diloxanide furoate and metronidazole. The first method depends on first derivative of the ratio-spectra by measurements of the amplitudes at 242.5 and 285.5 nm for diloxanide furoate and 225.5 and 300 nm for metrinidazole. Calibration graphs were established for 2-100 μg mL-1 for diloxanide furoate and 1-50 μg mL-1 for metronidazole.
