Research ArticleOpen accessIn the abstractThe Influence of the Climatic Factors on the Decay of Marbles: an Experimental StudyPaola Marini, Rossana BellopedeStone decay is affected by the influence of climatic factors. In particular marble degradation, that could be expressed by decohesion and /or bowing, is mainly due to the action of temperature and water (rains and relative humidity). In this work non destructive and destructive tests have been performed to evaluate the decay of marble slabs subjected both to natural exposition … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,123 accessesView PDFCite
Research ArticleOpen accessIn the abstractAFLPs in Warmblood Sporting Horses: Genetic Correlation with Height at the WithersV. Sanchez, C. Lemus, A. Inchaustegui et al.The Mexican army produces Warmblood horses for jumping proposes. However, breeding is based on phenotype and stallions are selected stepwise until the end of growth, representing a high care and maintenance cost. In this work using 64 selective primer combinations and AFLP technology we identified specific molecular markers related with height at the withers measurements of Warmblood horses. AFLPs generated … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 6,753 accessesView PDFCite
Research ArticleOpen accessIn the abstractFast Power Loss Computation and Shunt Capacitor Insertion Using Fuzzy Logic TechniqueWagah F. Mohammad, Nabil Tawalbeh, Kasim M. Al-AubidyFast power loss computation was implemented using supervisory control and data acquisition system (SCADA) with personal computer. Logic Control Array (LCA) and EPROM circuits were used to implement SCADA system to facilitate the required measurements to obtain the daily load profile for residential and commercial customers. LCA, EPROM and PC were used to simplify the electronic circuits, reduce the cost … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeep Defects Annihilation in GaAs1-xNx Layers by Si-dopingN. Ben Sedrine, A. Hamdouni, J. Rihani et al.The photoluminescence (PL) properties of Si-doped GaAs0.985N0.015 with different silicon content were investigated. The study was carried out on a set of three samples grown by Molecular Beam Epitaxy (MBE) on GaAs (001) oriented substrate using a radio frequency nitrogen beam source. For all samples, the PL measurements show the presence of a wide band situated at 0.83 eV which … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 8,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrofluorimetric Determination of Certain Fluoroquinolones Through Charge Transfer Complex FormationH. Salem, L. Fada, W. KhaterA highly sensitive spectrofluorimetric method was developed for the first time, for the analysis of ten fluoroquinolones (FQs) antibacterials, namely amifloxacin (AMI), ciprofloxacin (CIP), difloxacin (DIF), enoxacin (ENO), enrofloxacin (ENR), lomefloxacin (LOM), levofloxacin (LEV), norfloxacin (NOR), ofloxacin (OFL) and pefloxacin (PEF) in their pharmaceutical dosage forms or in biological fluids through charge transfer (CT) complex formation with bromanil (BRO). The … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 1 · 31 Mar 2007 · 7,629 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Quality and IndicatorsJorge Matute, A.P. GuptaThis study highlights the importance of collecting good quality data from multidisciplinary studies. Bias in data may be the result of instrument inaccuracies, imprecise data recording techniques, inaccurate data entry to computers or inappropriate statistical analysis and presentation. Recommendations for good data quality control are given. Different types of data are discussed: raw data, simple indicators and complex indicators. It … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 7,857 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. In … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,713 accessesView PDFCite
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 abstractMobile Agents in Heterogeneous Networks: A Look on PerformanceR. B. Patel, Neeraj GoelMobile agents can be seen as a new paradigm for distributed computing. One characteristic of mobile agents is their autonomy and pro-activity. This article present a framework designed on top of PMADE (Platform for Mobile Agent Distribution and Execution) to support our research in this domain. Our framework consists of three modules. The Map Module collects information on the available … …Journal of Computer Science, Vol. 2, Issue 11 · 30 Nov 2006 · 6,490 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting River Flow in the USA: A Comparison between Auto-Regression and Neural Network Non-Parametric ModelsAbdel K.M. Baareh, Alaa F. Sheta, Khaled A. KhnaifesForecasting a time series became one of the most challenging tasks to variety of data sets. The existence of large number of parameters to be estimated and the effect of uncertainty and outliers in the measurements makes the time series modeling too complicated. Recently, Artificial Neural Network (ANN) became quite successful tool to handle time series modeling problem.
