Research ArticleOpen accessIn the abstractComparative Study of Antibacterial Susceptibility Patterns of the Bacteria Isolated from Patients' Blood Samples over Two PeriodsAziz Japoni, Mehdi Kalani, Abdolvahab Alborzi et al.Problem statement: Due to continuous changes in the frequencies and antibacterial susceptibility patterns of nosocomial pathogens, periodical surveillance of these fluctuations could help the clinicians to treat hospitalized patients more efficiently whenever empirical therapies need to be considered. This study was conducted to compare the prevalence of the bacteria recovered from bloodstream samples by Bactec 9240, over the two periods … …American Journal of Infectious Diseases, Vol. 7, Issue 1 · 27 Apr 2011 · 8,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Edible Coatings, Storage Time and Maturity Stage on Overall Quality of Tomato FruitsJorge Esteban de Jesús Dávila-Aviña, José Villa-Rodríguez, Reynaldo Cruz-Valenzuela et al.Problem statement: Tomato (Lycopersicon esculentum Mill.) is one of the most widely consumed fresh vegetables in the world; however, its highly perishable nature limits its postharvest life. Major losses in tomato quality and quantity occur between harvest and consumption. Therefore, the application of new technologies to extend the postharvest life of this commodity is needed. The use of edible coatings … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 14 Mar 2011 · 11,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Combined Solution for Routing and Medium Access Control Layer Attacks in Mobile Ad Hoc NetworksR. Murugan, A. ShanmugamProblem statement: In Mobile Ad hoc Network (MANET), both the routing layer and the Medium Access Control (MAC) layer are vulnerable to several attacks. There are very few techniques to detect and isolate the attacks of both these layers simultaneously. In this study, we developed a combined solution for routing and MAC layer attacks. Approach: Our approach, makes use of … …Journal of Computer Science, Vol. 6, Issue 12 · 4 Nov 2010 · 7,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeptospirosis in the Tropics: When Prevention Doesn't Easily Sell as a Ton of CureRoger Lee MendozaProblem statement: Human leptospirosis -- the most widespread zoonotic disease -- thrives in tropical and subtropical climates. It is seldom addressed ex ante or prior to an outbreak or expected outbreak by governments of high-risk countries. Whether common, post-exposure treatment with antimicrobial drugs is more cost-efficient than reducing animal reservoir populations was the overarching question that guided this study. A … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 8,381 accessesView PDFCite
Research ArticleOpen accessIn the abstract2-Nonenal-Ovulatory Specific Volatiles in Human Saliva throughout Menstrual Cycle by Gas Chromatography and Mass Spectrometry AnalysisS. Alagendran, G. Archunan, K. Rameshkumar et al.Problem statement: The present investigation carry out a pilot study of a novel method to identify the salivary volatiles in different phases of menstrual cycle for the assessment of ovulation detection using gas chromatography and mass spectrophotometer. Approach: The profiles from follicular phase (6-12 days); ovulatory phase (13-14 days) and luteal phase (15-26 days) of menstrual cycle samples were compared … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 8,369 accessesView PDFCite
Research ArticleOpen accessIn the abstractSafety Message Power Transmission Control for Vehicular Ad hoc NetworksGhassan Samara, Sureswaran Ramadas, Wafaa A.H. Al-SalihyProblem statement: Vehicular Ad hoc Networks (VANET) is one of the most challenging research area in the field of Mobile Ad Hoc Networks. Approach: In this research we proposed a dynamic power adjustment protocol that will be used for sending the periodical safety message. (Beacon) based on the analysis of the channel status depending on the channel congestion and the … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 7,470 accessesView PDFCite

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 · 7,128 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Update Policy for Proactive Management of Deadline Miss Ratio and Data Freshness in Real-Time Database ModelsSanjay Tanwani, Ashwani K. RamaniImportant applications, like e-commerce, online stock trading, traffic control demand real-time data services. Conventional database perform poor at these applications. A database for real-time data services has to support timing constraints and temporal consistency in addition to supporting characteristics of a conventional database system. In other words, it is desirable to execute transactions within its deadline using updated data reflecting … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractSearching of Main Cause Leading to Severe Influenza A Virus Mutations and Consequently to Influenza Pandemics/EpidemicsGuang Wu, Shaomin YanThe unpredictable mutations in the proteins from influenza A virus lead to the great difficulty in prevention of possible outbreak of bird flu and pandemic/epidemic of influenza. This unpredictability is due to the fact that we know little about the causes that lead to the mutations. In three of our recent studies on the hemagglutinins from influenza A virus, we … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 9,975 accessesView PDFCite
