Research ArticleOpen accessIn the abstractA Transformation-oriented Methodology to Knowledge-based Conceptual Data Warehouse DesignOpim S. Sitompul, Shahrul A. NoahApplications of artificial intelligence (AI) technology in the form of knowledge-based systems within the context of database design have been extensively researched particularly to provide support within the conceptual design phase. However, a similar approach to the task of data warehouse design has yet to be seriously initiated. In this paper, we proposed a design methodology for conceptual data warehouse … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,731 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPreparing and Antimicrobial Activity of Hydrogel with Biosynthesized Silver Nanoparticles Using Carex Meyeriana KunthQihui Shen, Henan Zhu, Hongli Zhou et al.In this study, a simple and environmentally stable method was developed to synthesize silver Nanoparticles (AgNPs). In addition, carex meyeriana kunth was used as a reducing and stabilizing agent with good bacterial inhibitory effects against Escherichia coli (E. coli) and Bacillus subtilis at very low doses. AgNPs were added to the Polyvinyl Alcohol (PVA) solution as an antibacterial agent and … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 2 · 4 May 2023 · 5,724 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordProduction of Xylitol from Agricultural Waste by Enzymatic MethodsMarie K. Walsh, Hussein Fadhil Khliaf, Khalida A. ShakirEnzyme catalyzed production of xylose from autoclaved and non-autoclaved wheat straw was conducted followed by bioconversion of xylose to xylitol using a Crude preparation of Xylose Reductase (CXR) from Candida guillermondii. Ground wheat straw (autoclaved and non autoclaved) was treated at 40 and 50°C for up to 9 h at pH 4.5 with various concentrations of xylanase (12.4 to 37.2 … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 26 Mar 2018 · 9,655 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis and Optical Properties of ZnO-TeO2 Glass SystemH. A.A. Sidek, S. Rosmawati, Z. A. Talib et al.Problem statement: Systematic series of ZnO-TeO2 glasses with mole fraction of 0.10-0.40 ZnO content with an interval of 0.05 were studied to obtain their physical and optical properties. Approach: All the glass samples were synthesized by rapid melting quenching method under controlled conditions, while their refractive indices (n) were measured by the EL X-02C high precision ellipsometer. The room temperature … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 14,077 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesign, Synthesis, Biological Screening and Structure Activity Relationship Study of 4, 6-Dimethyl-2-(Substituted) Mercapto-3-(Substituted) Pyridines as Anti Tubercular AgentsMehul M. Patel, Mahesh T. ChhabriyaProblem statement: Tuberculosis is a leading global mortality factor which has not been effectively controlled, with 1.7 million deaths per year and 8.9 million new cases. Aerobic microbe Mycobacterium tuberculosis H37Rv (MTB) is the causative agent of tuberculosis. Although many active antitubercular agents have since been developed, drug resistance will continue to be a problem. Therefore, there is a clear … …American Journal of Infectious Diseases, Vol. 7, Issue 3 · 3 Nov 2011 · 7,430 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordA Multi-Criteria Optimization Approach to Cam Curve Design Combining Different Splines Given by Fixed and Adjustable CheckpointsLéo Moussafir, Vigen ArakelianThis study proposes a multi-criteria design optimization of cam mechanisms. This approach is based on the multistage interconnection of different tools: MATLAB, ADAMS, and mode frontier. It consists of three main issues: (i) The polynomial representation of splines given by checkpoints defining the specific motion of the follower; (ii) The connection of these splines by different degrees of fitting in … …Journal of Mechatronics and Robotics, Vol. 7, Issue 1 · 24 Mar 2023 · 6,646 accessesView PDFCite
Research NotesOpen accessAll words, across the recordEfforts to Know the Rate at which Students Analyze and Synthesize Information in Science and Social Science Disciplines: A Multidisciplinary Bio-Communication StudyDeni Darmawan, Yadi Ruyadi, Wamaungo Juma Abdu, Achmad HufadInformation processing is difficult to observe by most people because it involves self monitoring of one’s thinking. The process under which the cognitive functions is influenced by the rate at which different people analyze and synthesise information. However, though this is true, a measure of the speed in which information is processed is still new within the Indonesian perspective. Currently, … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 25 Aug 2017 · 7,590 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordInternal Combustion Engines ForcesRelly Victoria Virgil PetrescuThe paper presents an algorithm for determining the dynamic parameters of the internal combustion mechanism. Shows the force distribution (on the main engine mechanism) on internal combustion engines. Dynamically, tools can be distributed in the same way as forces. Practically, in dynamic regimes, speeds have the same synchronization with forces. The method applies separately for two distinct situations: When the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 23 Jul 2019 · 6,267 accessesView PDFCite
