Research ArticleOpen accessIn the abstractEr: YAG Laser Device for Taking Blood SamplesJosé L. Cabrera, Luis Ponce, Miguel Arronte et al.Problem statement: Secure methods for blood sampling which is performed at present by metallic lancets, has been a concern in the modern medicine in order to diminish the risk of contamination. A novel solution has appeared recently and consists in the use of laser pulses which ablates a tiny hole in skin. Approach: A laser device with Er: YAG active … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 7,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractConservation of “Partial Vorticity” with Application on Hydraulic JumpsHarald NaeserIn two preceding works, the idea of partial conservation theorems was introduced and conservation equations for partial energy and partial angular momentum were established. A similar conservation theorem for partial vorticity of incompressible fluids is established here. The vorticity vector is divided into two elements (both denoted “partial vorticity”) and their conservation equations established separately. They show that, in addition … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,707 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Control Strategy for Photovoltaic-Solid Polymer Electrolysis System Based on Surface Temperature of PV PanelRiza Muhida, Wahyudi, Rifki Muhida, Ahmad Unggul PriantoroProcesses to produce hydrogen from solar photovoltaic powered water electrolysis using solid polymer electrolysis are reported. An alternative control of maximum power point tracking method based on analysis of PV panel’s surface Temperature for the PV-SPE system was designed and implemented. From this analysis an optimal voltage of PV can be obtained and was realized as a reference voltage of … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,409 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordObservation Modeling for Continuous Predicting Global and Diffuse Solar Radiation on Horizontal SurfaceSomporn Hongkong, Singthong PattanasethanonMathematical modeling for continuous prediction of solar energy is inevitable for energy systems. General, existing models are mostly empirical and data dependent. This article has to present a variable model for predicting global and diffuse solar radiation on the horizontal plane. The model considered in this study has applied Hidden Markov Model (HMM) with two observations. The databases were measured … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 23 May 2013 · 6,799 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordLab-on-Chip Methodology in the Energy Industry: Wettability Patterns and Their Impact on Fluid Displacement in Oil Reservoir ModelsMarc H. Schneider, Patrick TabelingProblem statement: We present an experimental study of multiphase transport in porous media with controlled wettability patterns based on lab-on-chip methodology. Approach: Fractional, or patterned, wettability is known to have an enormous impact in the petroleum industry on oil recovery and continuous efforts are being made to assess the role of such conditions. Results: Thus far, due to the absence … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 7,885 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBioactive Compounds Screening from Zingiberaceae Family as Influenza A/Swine Flu Virus Neuraminidase Inhibitor through Docking ApproachUsman Sumo Friend Tambunan, Fadilah, Arli Aditya ParikesitProblem statement: Influenza A/H1N1 is a disease caused by infection of influenza a virus subtype H1N1. It is a major health problem in tropical and subtropical countries. This virus constantly mutates and consequently will be developed into new drug-resistant strains. Approach: In this research, we have conducted docking study to screen bioactive compounds from Zingiberaceae family, which has a role … …OnLine Journal of Biological Sciences, Vol. 10, Issue 4 · 31 Dec 2010 · 8,623 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAssessment of Suspended Sediments Concentration in Surface Waters, Using Modis ImagesMobasheri Mohammad RezaRemote sensing from air-borne and space-borne sensors have proved to be a useful method for Suspended Sediment Concentration (SSC) estimation as it provides an instantaneous and synoptic view of suspended sediments that would otherwise be unavailable. The reason for the success of remote sensing in such surveys is the strong positive relationship that exists between SSC and remotely sensed water … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,011 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMicrobial Biodiversity Screening for Metal Accumulators from Mineral Ore Rich Site in Andhra Pradesh, IndiaAditya Kumar Sarkar, Susmita Roy, Ananya Pal et al.Problem statement: Since the site selected for screening was a source of magnetite, the objective of this study was to isolate some groups of magnetotactic bacteria and microbes with potential of metal accumulation. Approach: The culture based approach was used for the study. Pure isolates obtained were characterized on the basis of morphology, biochemical tests, physiology as well as at … …OnLine Journal of Biological Sciences, Vol. 8, Issue 2 · 30 Jun 2008 · 7,553 accessesView PDFCite
