Research ArticleOpen accessIn the abstractGenetic Algorithm Based Probabilistic Motif Discovery in Unaligned Biological SequencesM. Hemalatha, K. VivekanandanFinding motif in biosequences is the most important primitive operation in computational biology. There are many computational requirements for a motif discovery algorithm such as computer memory space requirement and computational complexity. To overcome the complexity of motif discovery, we propose an alternative solution integrating genetic algorithm and Fuzzy Art machine learning approaches for eliminating multiple sequence alignment process. Problem … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpairment of Retrograde Neuronal Transport in Cardiac Vagal Motoneurons in Streptozotocin-Induced Diabetic Rats: A Wheat Ger Agglutinin-Horseradish Peroxidase Neurohistochemical studyA. Odekunle, C.M. PhillipsCentral projections of vagal motoneurons to the heart were studied in diabetic rats using Wheat germ Agglutinin-Horseradish peroxidase (WGA-HRP). Experimental rats were rendered diabetic by intraperitoneal injection of streptozotocin in citrate buffer. The diabetic rats were maintained in a stable diabetic state by daily injection of insulin for 24 weeks. Age-matched control rats were injected intraperitoneally with citrate buffer not … …OnLine Journal of Biological Sciences, Vol. 8, Issue 2 · 30 Jun 2008 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Diffusivity of Carbon Pellets (CPs) Treated with KOHM. Haydari, M. M. Moksin, A. E. Abdelrahman et al.In this work thermal diffusivity of carbon pellets (CPs) treated with different percentage level of KOH has been studied. Thermal diffusivity measurements were carried out at room temperature by using photoflash technique. The technique consists of a camera flash having approximately 5 ms pulse duration for heating and a thin film of polyvinylidene difluoride (PVDF) attached to the back of … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement ProductionMohd Sobri Idris, Khairul Nizar Ismail, Shamsul Baharin Jamaludin et al.Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of microstructure shows that the formation of belite minerals started at temperature nearly 1200°C which is at calcinations zone temperature, followed by formation of α±-belite at higher temperature (around 1300°C), then … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,498 accessesView PDFCite
Research ArticleOpen accessIn the abstractStop Conditions Of BB84 Protocol Via A Depolarizing Channel (Quantum Cryptography)Iyed Ben Slimen, Olfa Trabelsi, Houria Rezig et al.BB84 (Bennett and Brassard 1984) is one of the well known protocols of quantum keys distribution. It is built to allow two interlocutors commonly called Alice and Bob to share two similar binary keys and to detect the eavesdropper presence (the eavesdropper is commonly called Eve). However, Eve presence in a disturbed environment causes errors to the sifted keys and … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Heat Shock Transcription Factor Family in Entamoeba histolyticaConsuelo G. García, Ma. De la Luz Macias Argüelles, D. Guillermo P Ishiwara et al.The HSTF is a master molecule involved in the transcriptional control of several genes during different types of stress. This transcription factor is a very conserved protein identified in different organisms from bacterial to human. Entamoeba histolytica is the protozoan responsible for the human amoebiasis. This parasite is exposed to different kind of stress as changes in the pH, temperature, … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Trivalent Aluminum and Divalent Zinc in Drinking Waters by Differential Pulse Stripping VoltammetryAhmed HassanA Sensitive and precise differential- pulse stripping voltammetric method at static mercury dropping electrode (SMDE) has been applied to measure zinc(II) by anodic stripping at pH~¼4 and aluminum(III) by adsorptive cathodic stripping mode in presence of 1&Cross10-3M N,N` -bis-2-hydroxyethyl-2-amino-ethane sulphonic acid (BES) buffer at pH~7.1 and 2⨯10-5 M of alizarin red S as a ligand in drinking water samples purchased … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Text Mining Approach for Finding Protein-to-Disease AssociationsHisham Al-Mubaid, Rajit K. SinghDiscovering significant relationships between biological entities from text documents is an important task for biologists in order to develop biological models for research and discovery, especially with the existing gigantic amounts of biomedical documents and the rate at which they are increasing everyday. We propose a new text mining method to extract associations between biological entities from text documents; and … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 7,012 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotocurrent and Photoluminescence Investigations of GaInNAs and GaInNAs(Sb) Quantum Wells Grown by Molecular Beam EpitaxyS. Ben Bouzid, F. Bousbih, A Hamdouni et al.We have investigated photocurrent (PC) and photoluminescence (PL) in sequentially grown GaInNAs/GaAs and GaInNAs(Sb)/GaAsSbN quantum wells. Photocurrent transitions are analyzed by theoretical calculations using envelope function formalism taking into account the strain effect and the strong coupling between nitrogen localized state and the GaInAs band gap. The results are consistent with a type I band alignment and a conduction band … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrade-GDP Nexus in Iran: An Application of the Autoregressive Distributed Lag (ARDL) ModelMosayeb Pahlavani, Ed Wilson, Andrew C. WorthingtonThis study employed annual time series data (1960-2003) and unit root tests with multiple breaks to determine the most likely times of structural breaks in major factors impacting on the trade-GDP nexus in Iran We found, inter alia, that the endogenously determined structural breaks coincided with important events in the Iranian economy, including the 1979 Islamic revolution and the outbreak … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 8,516 accessesView PDFCite
