Research ArticleOpen accessIn the abstractEducational Attainment of Jordan's Population and Labor ForceMwafaq D. Al-KhaldiThe analysis of the educational attainment by Gender tells us about the general demand for education and qualitative change both in population and labor force. The term educational attainment used here refers to the actual level of education completed by a person as it is superior to the enrolment ratio - as a proxy for educational attainment - especially for … …Journal of Social Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 8,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of the Chi-square Test to Determine Significance of Cumulative Antibiogram DataRocco J. Perla, James CarifioAn important function of a hospital’s Infectious Disease and Pharmacy programs is to review and compare the most recent antibiogram with that of the previous year to determine if significant changes in antibiotic susceptibility results are noted and to communicate this information and its consequences to the medical staff. However, there are currently no formal analytical (decision-making) models in use … …American Journal of Infectious Diseases, Vol. 1, Issue 4 · 31 Dec 2005 · 7,279 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalytical Study of Reinforced Concrete Beams Strengthened by FRP Bars Subjected to Impact Loading ConditionsSajjad Roudsari, Sameer Hamoush, Sayed Soleimani et al.Civil engineers have considered Fiber Reinforced Polymer (FRP) materials to enhance the performance of structural members subjected to static and dynamic loading conditions. However, there are some design limitations due to uncertainty in the behavior of such strengthened members. This fact is particularly important when considering the complex nature of the nonlinear behavior of materials, the impact loading conditions and … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 Apr 2018 · 9,929 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 recordAnalytical Solution of Nonlinear Vibrating SystemsN. Tolou, I. Khatam, B. Jafari, D. D. GanjiThe responses of nonlinear vibrating systems are investigated analytically using Homotopy Perturbation Method (HPM). To demonstrate the validity of the proposed method, the results obtained by HPM have been depicted graphically and have been compared with those of the exact solution. A clear conclusion can draw from the numerical results that the method provides highly accurate solutions to the discussed … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,149 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalytical Study of Bending Behavior for Concrete Beams with T-Shaped Cross Section using Composite and Steel BarsSeyedeh Zahra Hosseini Ghaziyani, Seyedamin Mostafavian, Meysam Azizpour ChiraniTodays, instead of steel reinforcements, Fiber Reinforced Polymer (FRP) rebars have been using in the reinforced concrete structures. By consideration of different strain-stress behavior between steel and composite material, it is necessary to evaluate the difference of these two materials inside of RC beams. In this research, twelve reinforced concrete T-shape beams were modeled using ABAQUS finite element software. Six … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 2 Jun 2018 · 8,535 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Inverse Kinematics of the Plane System 2-3 in a Mechatronic MP2R System, by a Trigonometric MethodRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Robots have penetrated today in almost all industrial fields, being much more precise than humans in the execution of operations, but also faster, more dynamic, more stable and more resilient, working 24 h of the 24 h possible, in any season, breaks, holidays, vacations and especially without getting sick. The most important fact is that they can also perform special … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 20 Dec 2017 · 7,806 accessesView PDFCite
Case ReportOpen accessAll words, across the recordBending Stress and Deflection Analysis of Meshing Spur Gear Tooth during the Single Tooth Contact with Finite Element Method and Determination of the Bending StiffnessAntonios D. Tsolakis, Konstantinos G. Raptis, Maria D. MargaritouPurpose of this study is the study of loading and contact problems encountered at rotating machine elements and especially at tooth gears. Tooth gears are some of the most commonly used mechanical components for rotary motion and power transmission. This fact proves the necessity for improved reliability and enhanced service life, which requires precise and clear knowledge of the stress … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 3 Jun 2017 · 7,642 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUNSTEADY BOUNDARY LAYER FLOW ALONG A STRETCHING CYLINDER AN ANALYTICAL SOLUTIONM. Y. AklThe axisymetric laminar boundary layer unsteady flow along a continuously stretching cylinder immersed in a viscous and incompressible fluid is studied. The governing partial boundary layer equations in cylindrical form are first transformed into ordinary differential equations these equations are solved analytically using the optimal modified Homotopy Asymptotic method in order to get a closed form solution for the dimensionless … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 17 Feb 2014 · 7,152 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparative Studies of the Determination of Divalent Cadmium, Lead and Copper in the Boiling Medicinal Herbs by Stripping Voltammetry and by Atomic Absorption SpectrometryAhmed Hassan, Jamal A. MayoufCadmium, lead and copper were determined in ten Libyian boiling medicinal herbs samples by differential pulse anodic stripping voltammetry as well as by atomic absorption spectrometry. Voltammetric method was done at Hanging Mercury Dropping Electrode (HMDE) in Briton-Robinson buffer solution of pH ~2.1 at 25± 0.1°C. The sample preparation was carried out by boiling 2.0g of a finely pulverized plant … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,029 accessesView PDFCite
