Research ArticleOpen accessIn the abstractFabrication and Testing of a Medical Surgical Instrument Capable of Detecting Simulated Embedded LumpsJavad Dargahi, Siamak Najarian, Reza Ramezanifard, Farhad Tabatabai GhomsheA novel endoscopic grasper is being fabricated and tested. This grasper can be used in detecting lumps or tumors in biological tissues. The detailed fabrication process of the tactile sensor has been discussed. Custom-made sensors were integrated with the jaws of the endoscopic grasper and objects with known tactile features were tested by the designed grasper. Different experiments were performed … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,002 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobility Management Technique for Real Time Traffic in 802.11 NetworksGurpal Singh, Ajay Pal Singh Atwal, B.S. SohisA practical mobility management technique aimed at reducing handoff latency to less than 10ms has been proposed and implemented in this paper. Handoff latency has been reduced by decoupling scanning from handoff execution process. This scheme has been implemented in the form of client side application with modifications to open source Madwifi new generation driver. Performance of this mobility management … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,782 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 · 7,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiamond Pressing on the Wear Resistance and the State of Heat Treated Alloy Steel SurfacesUbeidulla Al-QawabehaIn manufacturing processes, surfaces and their properties are as important as the bulk properties of the materials. Surface treatment is an important aspect of all manufacturing processes. It has been used to impart certain physical and mechanical properties, such as appearance, corrosion, friction, wear and fatigue resistance. Widely used methods of finishing treatment that create necessary parts with the given … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,105 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrofluorimetric Study of the Charge-transfer Complexation of Certain Fluoroquinolones with 2,3,5,6-tetrafluoro-p-bezoquinoneD. Geffken, H. SalemA 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 fluoranil (TFQ).

Research ArticleOpen accessIn the abstractDesign of Output Codes for Fast Covering Learning using Basic Decomposition TechniquesAruna Tiwari, Narendra S. ChaudhariWe propose the design of output codes for solving the classification problem in Fast Covering Learning Algorithm (FCLA). For a complex multi-class problem normally the classifiers are constructed by combining the outputs of several binary ones. In this paper, we use the basic methods of decomposition; one per class (OPC) and Error Correcting Output Code (ECOC) with FCLA, binary to … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractNeuropsychological Consequences of HIV and Drug AuseArun Venkatesan, Ola Selnes, Valerie Wojna et al.Accurate assessment of the functional consequences of human immunodeficiency virus (HIV) infection and drugs of abuse are critical as large populations are afflicted with both. Both are interdependent epidemics with important socioeconomic consequences. Experimental studies in animal models and in vitro clearly indicate that HIV and drugs of abuse cause increased neurodegeneration, glial cell activation and enhanced HIV replication. Nevertheless, … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrequency Behavior of a Quartz Crystal Microbalance (Qcm) in Contact with Selected SolutionsZ. A. Talib, Z. Baba, S. Kurosawa et al.A device was constructed to monitor viscosity of solutions using fundamental frequency of 9 MHz and 10 MHz quartz crystal. Piezoelectric quartz crystals with gold electrodes were mounted by O-ring in between liquid flow cell. Only one side of the crystal was exposed to the solutions which were pumped through silicon tube by a peristaltic pump. The measured frequency shift … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 7,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Environmental Non-Governmental Organizations in Natural Resources Management Extension (Case Study in Iran)Iraj M. Mohammadi, Mehrdad MirbodThis study describes the emergence, development and functions of Environmental Non-Governmental Organizations (ENGO) and addresses their role and impact in Natural Resources Management Extension (NRME) in Iran. The study also attempts to describe the collaboration and support of government organizations managing natural resources, mainly National Forest and Pasture Organization (NFPO) and Environmental Conservation Organization (ECO) and locally based ENGOs in … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurface Roughness Prediction Model in Machining of Carbon Steel by PCD Coated Cutting ToolsYusuf Sahin, A. Riza MotorcuThe surface roughness model in the turning of AISI 1040 carbon steel was developed in terms of cutting speed, feed rate and depth of cut using response surface methodology. Machining tests were carried out using PVD-coated tools under different cutting conditions. The surface roughness equations of cutting tools when machining the carbon steels were achieved by using the experimental data. … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,968 accessesView PDFCite
