Research ArticleOpen accessIn the abstractDNA Sequence Optimization Based on Continuous Particle Swarm Optimization for Reliable DNA Computing and DNA NanotechnologyN. K. Khalid, Z. Ibrahim, T. B. Kurniawan et al.Problem statement: In DNA based computation and DNA nanotechnology, the design of good DNA sequences has turned out to be an essential problem and one of the most practical and important research topics. Basically, the DNA sequence design problem is a multi-objective problem and it can be evaluated using four objective functions, namely, Hmeasure, similarity, continuity and hairpin. Approach: There … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 7,046 accessesView PDFCite
Research ArticleOpen accessIn the abstractChelation Study of Captopril with Cd2+ and Pb2+ IonsMohammad Joshaghani, M.B. Gholivand, A.R. MosavatThe protonation constants of Captopril, (1-(3-mercapto-2-(S)-methyl-1-oxopropyl)-S(L) proline, (CPL) and stabilities of its two divalent metal ions Cd(II) and Pb(II) were determined potentiometrically in two different metal to ligand ratio 1:1 and 1:2 systems and in water and methanol-water binary mixtures using the computer Best program. Two protonation constants were obtained which were assigned to the carboxylic and thiol groups. All … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Unusual Association between Chromoblastomycosis and Jorge Lobo’s Disease in the Same Patient from the Amazon RegionMaurimelia M. da Costa, Silvia H. Marques da Silva, Hugo J. R. Almeida et al.A clinical case of co-infection Cladophialophora sp. and Lacazia loboi is described and in a same patient with an 18-year history of verrucous plaques and parakeloidal nodular lesions. A 50-yearold man, a laborer, living in the Anajás city, Para, Brazil (rural Amazon region), was seen at the Evandro Chagas Institute’s ambulatory. Histopathological analysis revealed intense hyperplasia and hyperkeratosis of the … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 7,747 accessesView PDFCite
Research ArticleOpen accessIn the abstractGraph Based Segmentation in Content Based Image RetrievalP. S. Suhasini, K. S.R. Krishna, I. V.M. KrishnaProblem statement: Traditional image retrieval systems are content based image retrieval systems which rely on low-level features for indexing and retrieval of images. CBIR systems fail to meet user expectations because of the gap between the low level features used by such systems and the high level perception of images by humans. To meet the requirement as a preprocessing step … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,581 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombining ANP and TOPSIS Concepts for Evaluation the Performance of Property-Liability Insurance CompaniesHui-Yin Tsai, Bao-Huey Huang, An Siou WangThis is a significant problem for the property-liability insurance industry. The study first uses Modified Delphi Method to sift influence property-liability insurance effects out norms. Moreover, the evaluation weights are determined using Analytic Network Process (ANP). Finally, the technique for ordering preference by similarity to the ideal solution (TOPSIS) constructs performance evaluation model of property-liability insurance companies in Taiwan. This … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 8,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractChaos Control in Nonlinear Systems Using the Generalized Backstopping MethodA.R. Sahab, M. Haddad ZarifOne of the most important nonlinear systems for checking the abilities of control methods is chaos. In this study chaos in Lorenz system was used for checking abilities of new control method. This new method to control nonlinear systems was called Generalized Backstepping method because of its similarity to Backstepping but its abilities to control more systems than Backstepping. This … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Mar 2008 · 7,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Simulation of 2_D Turbidity Currents and Wall JetM.H. Shojaeefard, K. Goudarzi, H. Ghasvari JahromiDense underflows are continuous currents, which move down the slope due to the fact that, their density are heavier than ambient water. In turbidity currents the density differences arises from suspended solids. Vicinity of the wall make density currents and wall jets similar in some sense but Variation of density cause this flows more complex than wall jets. An improved … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeature Selection in Data-Mining for Genetics Using Genetic AlgorithmV. N. Rajavarman, S. P. RajagopalanWe discovered genetic features and environmental factors which were involved in multifactorial diseases. To exploit the massive data obtained from the experiments conducted at the General Hospital, Chennai, data mining tools were required and we proposed a 2-Phase approach using a specific genetic algorithm. This heuristic approach had been chosen as the number of features to consider was large (upto … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,627 accessesView PDFCite
Research ArticleOpen accessIn the abstractVibrio cholerae O1 Strains of Different Ribotypes have Similar hlyA RFLP Patterns but Different Vacuolating AbilityJorge E. Vidal, Paula Figueroa-Arredondo, Silvia Giono-Cerezo et al.Extensive cytoplasmic vacuolation on Vero and HeLa cells in vitro by the Vibrio cholerae pore forming toxin HlyA, has been previously reported by our group. Vibrio cholerae O1 and non-O1 pathogenic strains show differences in the potential to induce vacuolation, here we study occurring variations on vacuolating cytotoxic ability, related to changes in the nucleotide sequence of the hlyA-orf. A … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 6,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Variation and Relationship Between Turkish Flint Maize Landraces by RAPD MarkersA. OkumusA comparative characterization of 17 flint maize landraces (Zea mays L.) was carried out using RAPD markers. Fourteen primers giving reliable and consistent polymorphic bands amplified 125 fragments (89%) with an average of 8.90 fragment per primer. Genetic variation in 17 maize landraces was characterized based on dissimilarity matrix by UPGMA dendogram which has no association into distinct grouping with … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 7,977 accessesView PDFCite
