Research ArticleOpen accessAll words, across the recordExact Classical and Quantum Mechanics of a Generalized Singular Equation of Quadratic Liénard TypeLucas H. Koudahoun, Jean Akande, Damien K.K. Adjaï et al.Authors introduce a generalized singular differential equation of quadratic Liénard type for study of exact classical and quantum mechanical solutions. The equation is shown to exhibit periodic solutions and to include the linear harmonic oscillator equation and the Painlevé-Gambier XVII equation as special cases. It is also shown that the equation may exhibit discrete eigenstates as quantum behavior under Nikiforov-Uvarov … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 5 Jul 2018 · 7,609 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordFitted Reproducing Kernel Method for Solving a Class of Third-Order Periodic Boundary Value ProblemsAsad Freihat, Radwan Abu-Gdairi, Hammad Khalil et al.In this article, the reproducing kernel Hilbert space W24 [0, 1] is employed for solving a class of third-order periodic boundary value problem by using fitted reproducing kernel algorithm. The reproducing kernel function is built to get fast accurately and efficiently series solutions with easily computable coefficients throughout evolution the algorithm under constraint periodic conditions within required grid points. The … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 11 May 2016 · 7,647 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDifferential Banding Pattern Based Identification of Urinary Tract Infection Causing BacteriaPoulomi Nandy, Md Aftabuddin, Ashoke Ranjan Thakur, Shaon RayChaudhuriUrinary Tract Infection (UTI) affects all age groups, but women are more susceptible than men. These infections are typically caused by E coli, Proteus mirabilis, Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterococcus fecalis and so on. Since uncultivable microbes are numerically abundant in urine samples, culture independent detection seems to be the method of choice for diagnosing UTI. This study … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 8,098 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMaximum Principles for Second Order Elliptic Equations in Nondivergence Form and ApplicationsMohammad Al-MahameedThe main objectives of this study were to introduce a maximum principle for second order elliptic equations in nondivergence form and to use a nondivergence technique called the ABP method to establish the maximum principles in small domains. The advantage of this work was that we obtain a maximum principle for equations with discontinuous coefficients of the leading terms and … …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 6,852 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPassage to the Differences for the BDF's MethodsAbdelouahab SalmiIn this study, we give an improvement to the backward differentiation formula (BDF). We use a formula for the differences that permits us to determine the new coefficients αi^ and γi ^in function of the classical coefficients αi and γi of this method. Our proposed approach decreases the error and the cost of computation. Numerical results for concrete problems are … …Journal of Mathematics and Statistics, Vol. 2, Issue 3 · 30 Sep 2006 · 6,412 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCervico-Facial Actinomycosis: Epidemiological and Clinical CommentsSilvia Tortorici, Francesco Burruano, Maria Lidia Buzzanca et al.In a retrospective investigation performed in the department of Surgical Odontostomatology of Palermo University Polyclinic from 1997-2006, the authors examined 12 cases of cervico-facial actinomycosis, taking into consideration age range, gender distribution, predisposing factors and symptoms. In concordance with reports in literature, they found that the disease was perimandibular in 65%, they also report the diagnostic methods and therapeutic approaches … …American Journal of Infectious Diseases, Vol. 4, Issue 3 · 30 Sep 2008 · 6,846 accessesView PDF Cite
