Research ArticleOpen accessEvery word in the titleTree Volume Prediction Model of Cupressus lusitanica Species: in North-Western Highlands of EthiopiaYishak Adgo Kassie, Abebaw Alene YallewA significant basis of raw materials for the forest products industry is provided by Cupressus lusitanica, one of the commercial timber tree species found in the forest. Accurate tree and stand volume development models are necessary for intensive forest management to yield timber. The goal of this study was to develop and validate volume equations for Cupressus lusitanica tree species … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 26 Aug 2025 · 5,936 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCredibility of 3D Volume Computation Using GIS for Pit Excavation and Roadway ConstructionsRagab KhalilVolume estimation and earthworks calculation of borrow pits and roadway constructions are typical applications in civil Engineering. Although several methods for volume estimation were introduced, the average end area method still the common method used by owners and contractors. Average end area method is tedious and time consuming. Volume of terrains that do not have regular geometric structure can be … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 1 Sep 2015 · 8,269 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleSelected Genotoxic Impurities Profiling During WFI Qualification to Control Carcinogenesis in Large Volume ParenteralsMohabbat UllahWater For Injections (WFI) which is the main vehicle of Large Volume Parenterals (LVPs) should be free from trace amount of genotoxic impurities. This review gives emphasis on quantification of genotoxic trace metals during qualification of WFI in LVPs manufacturing unit. According to ICH guidelines, impurities related to drug substances are classified into three main categories: Organic impurities, inorganic (elemental) … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 1 · 27 May 2015 · 7,708 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCAVITY SEGMENTATION AND STROKE VOLUME MEASUREMENT METHODS FROM ECHOCARDIOGRAPHIC IMAGES: REVIEWAnas A. Abboud, Rahmita Wirza Rahmat, Suhaini Bin Kadiman et al.The complexity and criticality of heart disease diagnosis and treatment have frequently attracted the attention of researchers to develop approaches that can handle accurate clinical assessments. One of these complexities is measuring the Right Ventricle stroke volume. Therefore, different cardiac imaging techniques have been developed to help specialists in their regular clinical work and in the operating theatre to assist … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,410 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFINITE VOLUME METHOD OF MODELLING TRANSIENT GROUNDWATER FLOWN. Muyinda, G. Kakuba, J. M. MangoIn the field of computational fluid dynamics, the finite volume method is dominant over other numerical techniques like the finite difference and finite element methods because the underlying physical quantities are conserved at the discrete level. In the present study, the finite volume method is used to solve an isotropic transient groundwater flow model to obtain hydraulic heads and flow … …Journal of Mathematics and Statistics, Vol. 10, Issue 1 · 15 Feb 2014 · 7,108 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMoringa Oleifera Lam Mitigates Oxidative Damage and Brain Infarct Volume in Focal Cerebral IschemiaWoranan Kirisattayakul, Jintanaporn Wattanathorn, Terdthai Tong-Un et al.Problem statement: At present, the therapeutic outcome of cerebral ischemia is still not in the satisfaction level. Therefore, the preventive strategy is considered. Based on the protective effect against oxidative damage of Moringa oleifera Lam. Leaves extract, we hypothesized that this plant extract might protect against cerebral ischemia, one of the challenge problems nowadays. In order to test this hypothesis, … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 3 Aug 2012 · 7,574 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReal-Time Volume Shadow using Visible-Non Visible AlgorithmHoshang Kolivand, Mohd Shahrizal Sunar, Azam Amirshakarami, Zhila RanjbariProblem statement: Shadows are most important effect to make realistic games and visually appealing images, but they are poor in frame per second. Silhouette detection is most important phases to create real-time shadow. Approach: Present study describes a real-time shadow generated with volume shadow algorithm using Visible-Non Visible algorithm (VNV) in virtual environment illuminated by a movable light source to … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,988 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis of Zeolite A from By-Product of Aluminum Etching Process: Effects of Reaction Temperature and Reaction Time on Pore VolumeKanokorn Hussar, Sombat Teekasap, Nisakorn SomsukProblem statement: Increasing of the carbon dioxide (CO2) concentration in the atmosphere creates a global warming. Zeolite is used as CO2 absorbent. Approach: By-products from aluminum etching process, which carry a large amount of Al2O3 content, are useable as raw materials for synthesis zeolites type A using hydrogel process. A pore volume of zeolites is the key to achieve high … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,836 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTrading Volume and Stock Indices: A Test of Technical AnalysisPaul AbbondanteProblem statement: Technical analysis and its emphasis on trading volume has been used to analyze movements in individual stock prices and make investment recommendations to either buy or sell that stock.
