Research ArticleOpen accessIn the abstractDetermining Optical Constants of Selenium Thin Films using the Envelope MethodNehad M. Tashtoush, Osamah ALkasassbehTwo Selenium thin films were deposited on glass substrates using thermal evaporation technique. The optical constants (refractive index, absorption coefficient and extinction coefficient and energy gap) were calculated using the Transmittance (T) spectrums of the films in the spectral range of 500-900 nm. The envelope method was used to determine optical constants. The calculated refractive index was found to be … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 15 Feb 2013 · 6,337 accessesView PDFCite

In terms of water levels, DID have introduced three categories of critical level stages namely normal, alert and danger levels. One of the … …Journal of Computer Science, Vol. 8, Issue 9 · 13 Aug 2012 · 7,792 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnt Colony Optimization for Capacitated Vehicle Routing ProblemW. F. Tan, L. S. Lee, Z. A. Majid, H. V. SeowProblem statement: The Capacitated Vehicle Routing Problem (CVRP) is a well-known combinatorial optimization problem which is concerned with the distribution of goods between the depot and customers. It is of economic importance to businesses as approximately 10-20% of the final cost of the goods is contributed by the transportation process. Approach: This problem was tackled using an Ant Colony Optimization … …Journal of Computer Science, Vol. 8, Issue 6 · 15 Mar 2012 · 10,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Pan Coefficient using M5 Model TreePakorn Ditthakit, Chaiyuth ChinnarasriProblem statement: Pan Evaporation has extensively been used for estimating reference Evapotranspiration (ETo) due to its simplicity, low cost, ease of data interpretation and application and suitability for locations with limited availability of meteorological data. With this method, the pan coefficient (Kp) is a key element to be determined as well as the pan Evaporation (Ep) data. Approach: This study … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 29 Feb 2012 · 8,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractLemon Pepper Fruit Extract (Zanthoxylum acanthopodium DC.) Suppresses the Expression of Inflammatory Mediators in Lipopolysaccharide-Induced Macrophages In VitroYanti, Theodorus Eko Pramudito, Nerissa Nuriasari, Katarina JulianaProblem statement: Lemon pepper fruits (Zanthoxylum acanthopodium DC.; Rutaceae) have been used as a traditional source against stomach ache by Batak people in North Sumatera province, Indonesia. However, its scientific evidence for treatment of inflammatory disorders particularly gastritis has not been reported. Approach: Here, we investigated the inhibitory effects of Lemon Pepper Fruit Extract (LPFE) against inflammatory biomarkers by conducting … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 14 Feb 2012 · 9,581 accessesView PDFCite
