Research ArticleOpen accessAll words, across the recordIdentification of Novel Human Immunodeficiency Virus-1 Integrase Inhibitors by Shape-Based Virtual ScreeningT.K. Omprakash, A. Thamarai Selvan, A. Shahul Hameed, S.P. GeethaProblem statement: Human Immunodeficiency Virus-1 (HIV-1) is causative agent of the immune system disease, Acquired Immune Deficiency Syndrome (AIDS). Majority of anti-HIV drugs target reverse transcriptase and protease enzymes. Toxicity and development of multidrug resistant HIV-1 virus strains are the reasons for studying new targets in HIV-1 replication process for identifying novel inhibitor with low toxicity and high activity. Approach: … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Dec 2010 · 7,191 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIdentification a Novel Raw-Starch-Degrading-α-Amylase from a Tropical Marine BacteriumZeily Nurachman, Alfredo Kono, Ocky Karna Radjasa, Dessy NataliaProblem statement: Bacteria from the surface of the tropical marine hard coral Acropora sp. were screened for producing raw-starch-degrading-α-amylase. Approach: Based on its 16s rDNA sequence, a bacterium that produced the highest amylolitic activity was identified as Bacillus amyloliquifaciens ABBD. The bacterial isolate secreted a α-amylase extracellularly and then the enzyme was partially purified by ammonium sulfate precipitation followed by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,329 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordError Vector Normalized Adaptive Algorithm Applied to Adaptive Noise Canceller and System IdentificationZayed RamadanProblem statement: This study introduced a variable step-size Least Mean-Square (LMS) algorithm in which the step-size is dependent on the Euclidian vector norm of the system output error. The error vector includes the last L values of the error, where L is a parameter to be chosen properly together with other parameters in the proposed algorithm to achieve a trade-off … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,208 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordE-Visas Verification Schemes Based on Public-Key Infrastructure and Identity Based EncryptionNajlaa A. Abuadhmah, Muawya Naser, Azman SamsudinProblem statement: Visa is a very important travelling document, which is an essential need at the point of entry of any country we are visiting. However an important document such as visa is still handled manually which affects the accuracy and efficiency of processing the visa. Work on e-visa is almost unexplored. Approach: This study provided a detailed description of … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,045 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEstimation under Multicollinearity: A Comparative Approach Using Monte Carlo MethodsD. A. Agunbiade, J. O. IyaniwuraProblem statement: A comparative investigation was done experimentally for 6 different Estimation Techniques of a just-identified simultaneous three-equation econometric model with three multi-collinear exogenous variables. Approach: The aim is to explore in depth the effects of the problems of multicollinearity and examine the sensitivity of findings to increasing sample sizes and increasing number of replications using the mean and total … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,531 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIdentification of Volatile Metabolites from Fungal Endophytes with Biocontrol Potential towards Fusarium oxysporum F. sp. cubense Race 4A.S.Y. Ting, S.W. Mah, C.S. TeeProblem statement: Fungal endophytes are widely studied for their potential as biocontrol agents towards fungal pathogens. In vitro assessments usually reveal their antibiosis and mycoparasitism nature, but little is understood regarding their production of volatile metabolites as mechanisms of antagonism. Approach: This study explored the potential of fungal endophytes in controlling the pathogen responsible for Fusarium wilt disease. Nine fungal … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 11,872 accessesView PDFCite
