Research ArticleOpen accessIn the abstractEnvironmental Issues in Jordan, Solutions and RecommendationsNidal A. Hadadin, Zeyad S. TarawnehJordan’s natural resources are limited to support population in a sustainable manner. However, its environment is exposed to a number of threats. In order to best explain Jordan’s environmental difficulties, it would be prudent to focus individually on each of these major concerns: water shortages, agriculture/land and air pollution. This study focuses on the environmental problems in Jordan and has … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 10,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Protocol Based on a Sedentary Agent for Mobile Agent EnvironmentsAbdelmorhit E. Rhazi, Samuel Pierre, Hanifa BouchenebThe main challenge when deploying mobile agent environments pertains to security issues concerning mobile agents and their executive platform. This paper proposes a secure protocol which protects mobile agents against attacks from malicious hosts in these environments. Protection is based on the perfect cooperation of a sedentary agent running inside a trusted third host. Results show that the protocol detects … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractRetinoids Chemosensitize Ovarian Cancer Cell Lines to Cisplatin Independent of Nuclear Receptors and p53Suresh Guruswamy, Doris M. BenbrookTreatment of ovarian cancer with cisplatin-based chemotherapy is highly toxic and is often followed by cancer recurrence. Repeated treatments with cisplatin frequently result in the development of resistance to this drug. Drugs with low toxicity that could enhance the tumor cell killing effects of cisplatin could potentially reduce the toxicity and enhance the efficacy of cisplatin. The mechanism of cell … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 4 · 31 Dec 2006 · 6,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpgrading of Light Dewaxed Oil through Hydrofinishing and Additives Blending for Producing Automatic Transmission FluidGamal Abdel-Nasser Gohar, Mohamed Sherif El-Gayar, Abd El-Moneim Ibrahim et al.Light dewaxed oil was produced through dewaxing process of the light waxy distillate raffinate of crude oil from Western Desert of Egypt using methyl ethyl ketone/toluene mixed solvent. Hydrofinishing process was used to remove the non-hydrocarbon constituents and to improve the physicochemical properties of the produced oils such as color, viscosity index, inhibition responses, oxidation and thermal stability. The operating … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractCPI-1189 Protects Against Dextran Sulfate Sodium-induced Colitis in MiceBeverley Greenwood-Van Meerveld, Karl R. TylerNitrone-related therapeutics (NRTs) represent a new class of small molecules potentially effective in the treatment of inflammatory bowel disease (IBD) by protecting cells from damage caused by excess inflammation and/or oxidative stress. The goal of this study was to determine the efficacy and potency of CPI-1189, a novel therapeutic agent, in dextran sulfate sodium (DSS)-induced colitis in mice. Mice received … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 3 · 30 Sep 2006 · 6,713 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpidemiologic Assessment of the Protective Effects of Smallpox VaccinationHiroshi Nishiura, Isao Arita, Markus Schwehm, Martin EichnerDespite smallpox eradication, the widely discussed possibility of a bioterrorist attack using a variola virus makes it necessary to review the epidemiology of smallpox and the effects of various vaccination schemes. This paper provides a literature review concerning the epidemiologic assessment of the protective effects of smallpox vaccination, with particular emphasis on the statistical and theoretical points of view. Although … …American Journal of Infectious Diseases, Vol. 2, Issue 1 · 31 Mar 2006 · 7,010 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Over-Voltages Produced by Lightning Strokes in the Power Transmission System in the Southern Region of Saudi ArabiaA. U. Al-Abdulaziz, S. M. Bashi, A. A. AlthubaitiThis study deals with the simulation of lightning strokes and their effects on power network in the southern region of Saudi Arabia. The network consists of main generating stations, substations and the power transmission lines. The transient performance of the system has been investigated using the EMTP (Electro Magnetic Transient Program). Some surges were introduced to the network as in … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractFault Detection of 3-Phase VSI using Wavelet-Fuzzy AlgorithmM. Rozailan Mamat, M. Rizon, M. S. KhannicheThe good knowledge and information about the fault mode behaviour of the PWM voltage source inverter is important to improve system design, protection and fault tolerant control. This paper develops a real-time condition-monitoring algorithm for 3-phase Pulse Width Modulation (PWM) inverter in fuzzy speed controlled induction machine. It is designed to detect and identify the transistor open-circuit fault and an … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractChromium (III) Removal and Recovery from Tannery Wastewater by Precipitation ProcessAbass Esmaeili, Alireza Mesdaghi nia, Reza VazirinejadChromium (III) salts are the most widely used chemicals for tanning processes, but 60-70% of total chromium salts reacts with the hides. In the other word, about 30-40% of the chromium amount remains in the solids and liquid wastes (especially spent tanning solutions). Therefore, the removal and recovery of the chromium content of these wastewaters are necessary for environmental protection … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 8,679 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Quality of Homeland Security and Health Care Systems: The Texas Rangers InitiativeEldo E. Frezza, Maurizio Chiriva-InternatiHealthcare facilities are an essential component of an emergency response system in case of nuclear, biological or chemical attack, but at the present time, are poorly prepared for an incident. Key elements of the healthcare facility response plan include prompt recognition of the incident, staff and facility protection, patient decontamination and triage, medical therapy, and coordination with external emergency response … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,216 accessesView PDFCite
