Research ArticleOpen accessIn the abstractUse of Cross-linking to Assess Subunit Interaction of Recombinant Human Coproporphyrinogen OxidaseJason R. Stephenson, Nancy E. Thomas, Jon A. Friesen, Marjorie A. JonesTo provide further evidence for a dimeric form of coproporphyrinogen oxidase reported using the conventional hydrodynamic methods, bifunctional cross-linkers were incubated with purified, recombinant human coproporphyrinogen oxidase to determine subunit interaction in solution. The use of cross-linkers provides an effective way to demonstrate subunit association and allows for assessment of activity upon covalent cross-linking. Following incubation with selected cross-linkers, enzyme … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,597 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreasing Effectiveness of IDS to Improve Security in IntranetUmesh Kumar Singh, A. K. Ramani, Narendra S. Chaudhari, Vandana GuptaToday Intrusion Detection Systems (IDS) are becoming one of the most important tools for intranet security. Research regarding Intrusion Detection Systems (IDSs) has become more active with the recent increases in illegal accesses to computer systems. Many researchers focus only on the techniques or mechanisms for detecting intrusions automatically, without considering the security of IDSs themselves. When an intruder attacks … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,148 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison between Structural Element of Building Systems in MalaysiaM. R. Abdul Kadir, W. P. Lee, M. S. Jaafar et al.The Industrialized Building System (IBS) was introduced in Malaysia in 1966, but it failed to establish itself on a continuous basis though there has been a sustained large market for residential projects even since. One of the reasons behind this shortcoming is the lack of scientific data on labor productivity that could convince policy maker. Hence, the objective of this … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,070 accessesView PDFCite
Research ArticleOpen accessIn the abstractDisplacement of Boron from the Silicon Crystal Nodes by Interstitial Si Atoms During Implantation and AnnealingM. Jadan, A. R. Chelyadinskii, V. Y. YavidThe process of boron displacement from the nodes into interstitial positions of interstitial Si atoms in silicon (Watkins effect) on the conditions of implantation and annealing has been investigated with the help of X-ray diffraction and electrical methods. It was revealed that the efficiency of the Watkins substitution is determined by the ion current density (level of ionization). With increasing … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocalization of Implanted Impurities in SiliconM. Jadan, Jihad S.M. AddasiLocalization of implanted boron impurities at the nodes and interstitial of silicon depending on the implantation current density has been studied by the X-ray diffraction and astrophysical methods. A shares of the impurity at the lattice sites increases with growing current density due to the instantaneous vacancy concentration and suppression of the impurity displacement from the sites by silicon interstitial. …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,714 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Reconstructed Basins Using Pattern Spectrum ProcedureP. RadhakrishnanSeveral classical and Fractal binary shapes, which are akin to geophysical shapes such as basins, lakes, and pore-grain spruce, are analyzed and characterized by employing various mathematical morphological transformations, and methods. By employing rhombus, square and octagon structuring elements, these shapes are decomposed into their skeletal networks and their corresponding skeletal network subsets are dilated to the respective degree by … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,933 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Note on the Role of Abstraction and Generality in Software DevelopmentPavol Návrat, Roman FilkornAlthough the evolving field of software engineering introduces many methods and modelling techniques, we conjecture that the concepts of abstraction and generality are among the fundamentals of each such methodology. This study proposed a formal representation of these two concepts, along with a two-dimensional space for the representation of their application. Based on the examples, we further elaborate and discuss … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Analysis of a Smart Multi Purpose Electronic Nose SystemMahmoud Z. Iskandarani, Nidal F. ShilbayehAn electronic nose system for multi application purposes is designed and tested. Our hardware design allows various types of sensors to be used for different applications. The system is capable of being interfaced to both analog and digital instruments with special filtering devices that isolate the system from surrounding signals. The design of the system is distinguished through the use … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractRandom Amplified Polymorphic Dna-PCR Typing of Vibrio parahaemolyticus Isolated from Local Cockles (Anadara granosa)Lesley Maurice Bilung, Son Radu, Abdul Rani Bahaman et al.Randomly amplified polymorphic DNA (RAPD) was used in this study to examine the genetic relatedness among the Vibrio parahaemolyticus strains. In the analysis by RAPD-PCR, the size for RAPD fragments ranged from 0.25 to 10.0 kb with average number of ten bands. The RAPD profiles revealed a high level of DNA sequence diversity within the Vibrio parahaemolyticus strains tested. Hence, … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 8,611 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Control of Fusarium oxysporum f. sp. melonis, the Causal Agent of Root Rot Disease of Greenhouse Cucurbits in Kerman Province of IranSara Shafii Bafti, Gholam H.S. Bonjar, Sonia Aghighi et al.Antagonistic activity of 178 soil actinomycete isolates was assayed against Fusarium oxysporum f. sp. melonis Schlecht, Emend (Snyde and Hansen) cause of root rot and fusarium wilt of greenhouse cucurbits in Kerman Province, southeast of Iran. From tested isolates, Streptomyces olivaceus (strain 115) showed anti-fusarium activity revealed through screening and bioassays by agar disk and well-diffusion methods.
