Research ArticleOpen accessIn the abstractAnalysis of Certain Tetracyclines and Oxytetracyclines through Charge Transfer ComplexationKhairi M.S. FahelelbomProblem statement: Several studies were carried out to develop and validate a simple, rapid and accurate spectrophotometric method for the analysis of tetracycline (TC) and oxytetracycline (OTC) in the pure form and in pharmaceutical dosage forms, despite the varieties of these analytical techniques, the literature revealed that no spectrophotometric method for determination of tetracycline and oxytetracycline using charge transfer complexation … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 3 · 30 Sep 2008 · 8,528 accessesView PDFCite
Research ArticleOpen accessIn the abstractVariables Refinery Process to Ensure Research Unbiasedness (Validity) and Invariance (Reliability) in Agricultural Extension and EducationIraj Malek MohammadiInvolving many variables, usually uncertain discrete, lowers the level of consistency and certainty in complex human studies like agricultural extension education. This research, as a part of a study entitled: Side by side situational analysis of current versus future situations of agricultural sector in manifesting the Ninth Malaysia Plan, is dealing primarily with the purpose and process of refining a … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,652 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Quality of Service Guarantee in an Asynchronous Transfer Mode (ATM) NetworkFrancis Joseph Ogwu, Mohammad Talib, Ganiyu Adesola AderounmuThis study presents a technique for improving the quality of service (QoS ) guarantee in an ATM network. In the proposed model, it was assumed that high priority traffic have been allocated a switch resource to guarantee a given QoS and low priority cells are allowed to enter the buffer, to improve the exploitation of reserved resources. The proposed technique … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlow of Dividends under a Constant Force of InterestJuma Kasozi, Jostein PaulsenThis study addresses the issue of maximization of dividends of an insurer whose portfolio is exposed to insurance risk. The insurance risk arises from the classical surplus process commonly known as the Cramér-Lundberg model in the insurance literature. To enhance his financial base, the insurer invests in a risk free asset whose price dynamics are governed by a constant force … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,386 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolving Linear Programming Problems on the Parallel Virtual Machine EnvironmentJrJung Lyu, Hsing Luh, Ming-Chang LeeThis study developed a parallel algorithm to efficiently solve linear programming models. The proposed algorithm utilizes the Dantzig-Wolfe Decomposition Principle and can be easily implemented in a general distributed computing environment. The analytical performance of the well-known method, including the speedup upper bound and lower bound limits, was derived. Numerical experiments are also provided in order to verify the complexity … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,837 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalytical Fractured Reservoir Characterization by using Geological and Petrophysical LogsZohreh Movahed, Farzaneh AghajariDue to structural complexities in some wells, higher than the expected thickness of the Asmari formation is found. Fracture intensity and deep-rooted fractures broadly increase the risk of unpredictable water production. The well-test analysis is not sufficient in describing fracture properties. Unfortunately, the core condition is poor in the fractured zones and cannot be used to provide reliable information. So, … …Current Research in Geoscience, Vol. 12, Issue 1 · 3 Dec 2022 · 9,927 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Analytical Survey of Difficulty Faced in an Online Lecture During COVID-19 Pandemic Using CRISP-DMManmohan Singh, Vinod Patidar, Shaheen Ayyub et al.COVID-19 has greatly disturbed life in many ways and has changed the way we live. Various surveys have been conducted in different fields, and the teaching-learning process has been affected to a great extent. During this pandemic, various online tools and technologies have been available for guiding students without attending school. Many governments, corporations, and research fields have officially ordered … …Journal of Computer Science, Vol. 19, Issue 2 · 28 Jan 2023 · 6,350 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSpread Foundations on Rigid Inclusions Subjected to Complex Loading: Comparison of 3D Numerical and Simplified Analytical ModellingDaniel Dias, Bruno SimonThis paper relates results of a large number of 3D numerical models of a single spread footing over a soil reinforced by four rigid inclusions and submitted to a large set of complex loading. This numerical study using the FLAC 3D software was done under funding of the ASIRI research project in an aim to support appropriate guidelines for design … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 12 Sep 2015 · 6,842 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAssessment of Useful Life of Lubricants Using Analytical Hierarchy Process (AHP) and Vector Projection Approach (VPA)Surachai Bovornsethanant, Somchai WongwisesProblem statement: In general, engine oil is usually changed as defined by car or lubricant manufacturers, which is according to mileage. However, it was found from past researches that, at the predefined mileage or timeframe, most lubricant is still acceptably usable and efficient. Approach: This research aimed to calculate useful life of lubricant in order to reach its maximum usefulness. … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,640 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNumerical Study of Static Instability of Pipe Conveying Incompressible Fluid under Different Boundary ConditionsDahmane Mouloud, Zahaf Samir, Sid Ahmed Slimane et al.In this article, the influences of uniform velocity profile, mass ratio, length and Winkler elastic foundation on the static instability of pipe conveying incompressible fluid are investigated. The Euler-Bernoulli beam theory is employed to derive partial differential equation of pipes carrying fluid. The results were carried out using ANSYS Workbench program, where the analysis is based on the numerical solution; … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 26 Nov 2020 · 6,577 accessesView PDFCite
