Research ArticleOpen accessIn the abstractIn Vitro Activity of Cephalexin against Community-Acquired Urinary Escherichia coli, Klebsiella and Proteus species IsolatesHumodi A. Saeed, Amira Saad Eldin MohammedProblem statement: Resistance among urinary tract pathogens to conventional antibiotics has been considered a health problem worldwide. The aim of this study was to evaluate the in vitro activity of cephalexin on urinary enterobacterial isolates. Approach: Patients with community-acquired urinary tract infections were microbiologically investigated. Urine specimens were collected from each patient. The specimens were cultured on bacteriological media. The … …American Journal of Infectious Diseases, Vol. 6, Issue 4 · 31 Dec 2010 · 8,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntimicrobial Properties of Newly Synthesized Derivatives of CoumarineS. Govori, S. Spahiu, V. Kalaj et al.Problem statement: Coumarins are well known for their biological activity. On the basis of that we have synthesized some new derivatives of coumarine and investigated their antimicrobial properties. Approach: 4-Heteroaryl-coumarin-3-carbaldehydes 4(a-d) are synthesized by condensation of 4-chloro-coumarin-3-carbaldehydes 2 and corresponding heterorylamines 3(a-d) under reflux reaction conditions. Antimicrobial properties of new coumarins 4(a-d) are investigated and results are submitted for their … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,679 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of the Parameters of the Stochastic Differential Equations Black-Scholes Model Share Price of GoldKhaldi Khaled, Meddahi SamiaProblem statement: The estimation of the parameters is one of main problems of the dynamic models in many scientific fields and particularly in economics and finance. In this study, we examine the techniques of estimation of the parameters of the Black-Scholes model. These techniques are based on the function of probability. Approach: The two estimations are based on the likelihood … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 24 Dec 2010 · 7,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractDFM of Strained-Engineered MOSFETs Using Technology CADT. K. Maiti, C. K. MaitiProblem statement: In this study, a systematic study based on Technology CAD (TCAD) was taken up for the design and Virtual Wafer Fabrication (VWF) of strain-engineered MOSFETs in Si CMOS technology. Approach: A simple manufacturable process recipe was developed to induce uniaxial stress in channel region to obtain enhanced performance in CMOS in 45 nm technology node. Results: Using Synopsys … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 7,668 accessesView PDFCite
Research ArticleOpen accessIn the abstractDrying Characteristics of Chili Using Continuous Fluidized-Bed DryerSuparerk Charmongkolpradit, Kittichai Triratanasirichai, Narong SrihajongProblem statement: The objective of this study was to obtain the dying characteristics of the Jinda chili, a commonly grown variety in the Northeatern of Thailand, using the continuous fluidizedbed dryer in reducing moisture content of dried chili up to 13% wet basis as comparable to the dried chili in the market and to investigate the effect of drying temperature … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeckle Suppression of Radar Images Using Normalized ConvolutionA. K. Helmy, G. S. El-TaweelProblem statement: Synthetic Aperture Radar (SAR) images are becoming more widely used in remote sensing applications. SAR uses microwave radiation to illuminate the earth's surface. The coherent microwave illumination, however, suffers from fading effects result in generating a multiplicative speckle noise that corrupts SAR images. Approach: Through this study, scheme to reduce speckles was proposed, it was designed to accomplish … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence and Antibiotics Susceptibility of Uropathogens in Patients from a Rural Environment, TamilnaduMaripandi Arjunan, Ali A. Al-Salamah, M. AmuthanProblem statement: Urinary Tract Infections (UTIs) in human, rural environment cause significant morbidity due to insanitary condition, lack of knowledge of personal hygiene, lack of patient’s compliance and economic burden. In our study, the bacterial etiologies and the resistance patterns found in human with serious UTIs and selecting optimal antimicrobial therapy. Approach: A total of 105 patients first morning mid … …American Journal of Infectious Diseases, Vol. 6, Issue 2 · 30 Jun 2010 · 8,712 accessesView PDFCite
