Research ArticleOpen accessIn the abstractExperimental Study of Parameters Influencing the Purity of Potassium Sulfate Fertilizer Produced from Jordanian Raw MaterialsMousa GougazehThe general objective of the present investigation was to make a contribution towards improving the purity of the produced potassium sulfate from (KCl, Arab Potash Company-Dead Sea) and (H2SO4, Jordanian Phosphate Company). The process parameters influencing the contamination of the poisoning chlorine within the product were experimentally investigated. The experiments were performed in a small-scale batch reactor equipped with a … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,042 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction, Yield and Derivatives of Volatile Oils from Eastern Redcedar (Juniperus Virginiana L.)Elif Semen, Salim HizirogluEastern redcedar (Juniperus virginiana L.) is one of the most widely distributed indigenous conifers in southern states including Oklahoma, Arkansas and Texas. Eastern redcedar is also an important source of the volatile oils. This specie adversely influences the environment resulting in degrading grassland, displacement of native plant population and increasing wildlife hazard. Range-grown eastern redcedar has a poor quality. However, … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,754 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosensor Based on Xanthine Oxidase for Monitoring Hypoxanthine in Fish MeatHelena S. Nakatani, Luciane V. dos Santos, Cristiano P. Pelegrine et al.An amperometric enzyme electrode for the detection of hypoxanthine in fish meat is described. The hypoxanthine sensor was prepared from xanthine oxidase immobilized by covalent binding with glutaraldehyde and bovine serum albumin on a nafion-coated platinum disc electrode. The responses for hypoxanthine were obtained in 0.1 mol L-1 phosphate buffer (pH 7.0), at potential of 600mV vs Ag/AgCl. This biosensor … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 8,597 accessesView PDFCite
Research ArticleOpen accessIn the abstractConsumer's Acceptability Estimation of Cold Preserved Malaysian Freshwater PatinA. S. Mokhtar, K. A. Abbas, S. M. Sapuan, M. M.H. AhmadThe study presents an attempt to correlate the consumer acceptability of Malaysian Patin fish with the storage time and temperature. A batch of typical fresh fishes was cut into regular slices (samples), which were wrapped and distributed evenly to four cold stores by 0, 3, 5 and 10°C storage temperature for a period of 28 days. During the course of … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractBuilding Cost Comparison Between Conventional and Formwork System: A Case Study of Four-storey School Buildings in MalaysiaNuzul Azam Haron, Ir. Salihuddin Hassim, Mohd. Razali Abd. Kadir, Mohd Saleh JaafarThe Malaysian construction industry is undergoing a transitional change from an industry employing conventional technology to a more systematic and mechanized system. This new system is now known as the Industrialized Building System (IBS). This new method of construction can increase productivity and quality of work through the use of better construction machinery, equipment, materials and extensive pre-project planning. This … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 9,020 accessesView PDFCite
Research ArticleOpen accessIn the abstractScheme for ISDN/DECT Wireless Internetworking and VerificationMaher Dababneh, Ibrahim QatawnehA novel scheme to access the basic rate service of the Integrated Service Digital Network (ISDN) using the Digital Enhanced Cordless Telephone (DECT) radio interface standard is presented. The S-interface in the ISDN reference configuration has been used for the ISDN interface and the unprotected class 0 transmissions are used for the DECT interface. The design of a state of … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractCohesion Metrics for Ontology Design and ApplicationHaining Yao, Anthony M. Orme, Letha EtzkornRecently, domain specific ontology development has been driven by research on the Semantic Web. Ontologies have been suggested for use in many application areas targeted by the Semantic Web, such as dynamic web service composition and general web service matching. Fundamental characteristics of these ontologies must be determined in order to effectively make use of them: for example, Sirin, Hendler … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 149,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Performance of Traffic Dependent Outage Rate Cellular SystemHussein M.A. Basi, M. B.R. MurthyThe designers of a mobile cellular system must evaluate the possible configurations of the system components and their characteristics in order to develop a system with greater efficiency. The useful parameters to estimate performances of the system are voice quality, frequency spectrum efficiency and grade of service (GOS). In this study, a scheme proposed to reduce the lost calls and … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Reconfiguration of IP Domain Middleware Stacks to Support Multicast Multimedia Distribution in a Heterogeneous EnvironmentKevin Curran, Gerard ParrSeamless connectivity to multiple wireless networks independently of a fixed point is becoming increasingly important for mobile devices however wireless networks differ in bandwidth, size and access costs each requiring protocol functions to enable devices to communicate efficiently. In addition, due to the divergence of users and applications, traditional stacks are frequently enriched with additional functionality such as transport protocol … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,781 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,883 accessesView PDFCite
