Double Discontinuous Inverse Problems for Sturm-Liouville Operator with Parameter-Dependent Conditions
(HINDAWI PUBLISHING CORPORATION, 2013)The purpose of this paper is to solve the inverse spectral problems for Sturm-Liouville operator with boundary conditions depending on spectral parameter and double discontinuities inside the interval. It is proven that ... -
Double quantum well electronic energy spectrum within a tilted magnetic field
(ACADEMIC PRESS LTD, 1999)The analytical solutions of the Schrodinger equation for a double quantum well structure (DQWS) subjected to an externally applied tilted magnetic field are obtained and the results are discussed. The dependency of the ... -
Dragline cycle time analysis
(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2005)Draglines operate in a cyclic nature. Excluding the infrequent walking, a dragline spends its major operational time by digging the dirt and paying it out on a spoil pile. Considering the fact that a dragline performs tens ... -
Dramatic oral findings belonging to a pica patient: A case report
(WILEY, 2009)Pica is a compulsive eating of non-nutritive substances and can have serious medical implications. The causes are not known, but the symptom is often associated iron-deficiency. Pica is an under-diagnosed problem. Although ... -
Dronedarone: A Promising Alternative for the Management of Atrial Fibrillation
(SPRINGER, 2009)Atrial fibrillation (AF) is the most frequently encountered chronic arrhythmia associated with significant morbidity. It is generally encountered in the elderly, and will presumably become more prevalent in the future due ... -
Drug Adherence in Patients With Nonvalvular Atrial Fibrillation Taking Non-Vitamin K Antagonist Oral Anticoagulants in Turkey: NOAC-TR
(SAGE PUBLICATIONS INC, 2018)Adherence to non-vitamin K antagonist oral anticoagulants (NOACs) is an important factor for ensuring efficacy and safety in nonvalvular atrial fibrillation (NVAF). There are controversial results regarding NOAC adherence ... -
