Research ArticleOpen accessIn the abstractThe "New Settlers": Results of a Bacteriological Survey During the First 6-Months Operation Period of an Internal Medicine Ward in a Tertiary HospitalGad Segal, Adi Brom, Erez RamatiDuring the first six months of operating a new Internal-medicine ward in a tertiary hospital, a prospective survey, tracking both patient and environment bacteriological samples taken, was conducted. The motive behind the study was to establish the pattern in which environmental colonization is transmitted to the hospitalized patients and vice versa, thus defining the nosocomial pathogens that are typical to … …American Journal of Infectious Diseases, Vol. 9, Issue 4 · 27 Nov 2013 · 6,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Evaluation of a Low-Density Biomass Feeding System for Fluidized Bed GasifiersA. E. Ghaly, A. Ergudenler, S. Alsuhaibani, V. V. RamakrishnanFor efficient operation of a biomass gasifier, the biomass material must be fed continuously to the system. A feeding system for chopped straw and rice husk was designed, constructed and evaluated. It consisted of: a frame, a hopper, an auger, two agitators, a drive system and a power unit. Initial testing showed that wheat straw and rice husk, being highly … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 7 Nov 2013 · 8,045 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevention and Prophylaxis of Tick Bites and Tick-Borne Related DiseasesLara Garcia-Alvarez, Ana Maria Palomar, Jose Antonio OteoTicks are obligate haematophagous arthropods present all over the world able to produce human diseases. Several factors have increased the abundance, circulation and distribution of the pathogens transmitted by ticks, contributing to the change in the vector-borne diseases epidemiology in the last years. This review collects the most important measures for the prevention and prophylaxis of tick-borne diseases. The pre-exposition … …American Journal of Infectious Diseases, Vol. 9, Issue 3 · 5 Nov 2013 · 7,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Orthogonal Frequency Division Multiplexing Based Bidirectional Relay Network in the Presence of Phase NoiseV. N. Senthil Kumaran, S. Rajkumar, S. J. ThiruvengadamIn this study, the performance of OFDM based bidirectional relay network which employs Physical Layer Network Coding (PLNC) is analyzed in the presence of phase noise. The bidirectional relay network is assumed to consist of two sources and a relay, where each node has a single antenna and operates in half duplex mode. The PLNC based OFDM system transmits high … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 9 Sep 2013 · 6,644 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Channel Estimation Technique for Complexity Reduction of Least Minimum Mean Square ErrorHany Mohamed El-Ansary, Hussein Ghouz, Ashraf Mamdouh Aziz, Gamal MabroukChannel estimation technique is to predict the frequency response of the radio channel using pilot signal. Channel estimation technique is important part of LTE receiver design. Such technique is used to recover the transmitted signal correctly and to know how the channel conditions are changed over frequency and time. Each channel estimator has a specified complexity computed according to its … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 5 Sep 2013 · 7,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Analysis on Same Filter Different Sources for Selection of Spectral Filters in Optical DemultiplexerMohammad Syuhaimi Ab-Rahman, Hadiguna, Latifah Sarah SupianThe cost effective demultiplexer based on POF is reported in this study. The demultiplexer is fabricated by combining optical splitter with the suitable filter for wavelength selection. Therefore this study we aims to evaluate the effectiveness of selected color filter film for demultiplexer construction where only signals with certain wavelengths are allowed to pass through the demultiplexer while the other … …Journal of Computer Science, Vol. 9, Issue 7 · 18 Jun 2013 · 6,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Non-Iterative Method for Factorization of Positive Matrix in Discrete Wavelet Transform Based Image CompressionNallathai Perumalsamy, Nithyanandam NatarajanA non-iterative method of factorizing a 4×4 positive matrix, with the application to image compression is explained using an example. The procedure is applied to all the 4096 number of 4×4 pixel sub-blocks of a 256×256 image for compression. The proposed compression technique can be applied to the Discrete Wavelet Transform (DWT) coefficients of the test image. The 16 Pixel … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 6,547 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransmission Model of Chikungunya Fever in the Presence of Two Species of Aedes MosquitoesSurapol Naowarat, I. Ming TangIn 2008 there was a large outbreak of Chikungunya fever in the south of Thailand. Chikungunya fever is a febrile disease transmitted to humans by the bite of infected Aedes mosquitoes. The symptoms of this disease are a sudden onset of a fever, chills, headache, nausea, vomiting, joint pain with or without swelling, low back pain and rash. In this … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 27 May 2013 · 7,232 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelection of Spectral Filters for Optical Demultiplexer Via Same Source Different Filters Testing TechniqueMohammad Syuhaimi Ab-Rahman, Hadiguna, Latifah Sarah Supian, Malik SulaimanThis study aims to evaluate the effectiveness of selected color filter film for demultiplexer construction where only signals with certain wavelengths are allowed to pass through the demultiplexer while the other signal that carrying different wavelengths are absorbed.
