Antioxidant and antihypertensive properties of phenolic-protein complexes in extracted protein fractions from Nigella damascena and Nigella arvensis
( Elsevier , 2016 , Article)The study involved the investigation of the antioxidant and antihypertensive properties of the phenolic–protein complexes obtained from isolated protein fractions from Nigella damascena and Nigella arvensis. Protein fractions ... -
Higher order self-adjoint operators with polynomial coefficients
( Texas State University - San Marcos , 2017 , Article)We study algebraic and analytic aspects of self-adjoint operators of order four or higher with polynomial coefficients. As a consequence, a systematic way of constructing such operators is given. The procedure is applied ... -
Organic floating gate memory structures
( Springer International Publishing , 2017 , Book chapter)[No abstract available] -
Linear profile monitoring using EWMA structure under ranked set schemes
( Springer London , 2017 , Article)In many manufacturing processes, study variable is not the only quality characteristic, but there may exist some explanatory variable(s) that are associated with the study variable. This association may be linear or nonlinear ... -
The theta-complete graph Ramsey number R(θn K5) = 4n - 3 for n = 6 and n≥ 10
( Charles Babbage Research Centre , 2017 , Article)For any two graphs F1 and F2, the graph Ramsey number r(F1, F2) is the smallest positive integer N with the property that every graph of at least N vertices contains F1 or its complement contains F2 as a subgraph. In this ... -
Preliminary Test Estimation of the Threshold in the Two-Parameter Exponential Distribution Based on Records and Minimax Regret Significance Levels
( Taylor and Francis Ltd. , 2017 , Article)SYNOPTIC ABSRACT: We consider preliminary test estimation of the threshold parameter of the two-parameter exponential distribution using record-breaking data. We use the minimax regret criterion on the risk function of the ... -
Synthesis and characterization of Cu-doped TiO2 thin films produced by the inert gas condensation technique
( Institute of Physics Publishing , 2017 , Conference Paper)The bandgap of thin films Cu-doped TiO2 nanoclusters prepared using the inert gas condensation (IGC) technique have been investigated at various Cu contents. The samples were characterized using XRD, SEM/EDS and UV-visible ... -
Vacuum structure and PT -symmetry breaking of the non-Hermetian (iϕ3) theory
( American Physical Society , 2017 , Article)In this work, we study the PT -symmetric (iϕ3) theory using the effective action formalism. To test the accuracy of the used technique, we apply it first to the PT -symmetric (−ϕ4) theory, where we reproduce the same results ... -
Theoretical analysis of upper-convected Maxwell fluid flow with Cattaneo-Christov heat flux model
( Physical Society of the Republic of China , 2017 , Article)This paper discusses the mixed convection three-dimensional boundary layer flow of upper-convected Maxwell fluid over a stretching surface with Cattaneo-Christov heat flux model. Magnetohydrodynamic (MHD) combined with ... -
Utilization of simulated patients to assess diabetes and asthma counseling practices among community pharmacists in Qatar
( Springer Netherlands , 2017 , Article)Background Patient counseling is one of the most important services a pharmacist can provide to patients. Studies have shown that counseling provided by pharmacists may prevent medication related problems and improve ... -
Optimal control of a time-varying system of coupled parabolic-hyperbolic PDEs
( IEEE Computer Society , 2017 , Conference Paper)This paper is devoted to design an optimal linear quadratic controller for a time-varying system of coupled parabolic and hyperbolic partial differential equations (PDEs). Infinite-dimensional state space approach is adopted ... -
Dark soliton scattering in symmetric and asymmetric double potential barriers
( Elsevier B.V. , 2017 , Article)Motivated by the recent theoretical study of (bright) soliton diode effects in systems with multiple scatterers, as well as by experimental investigations of soliton-impurity interactions, we consider some prototypical ... -
New Multiple-kink solutions and singular-kink-solutions of (2 + 1) - Dimensional coupled burgers system with time variable coefficients
( American Scientific Publishers , 2017 , Article)In this paper, we show that the (2+1)-dimensional coupled Burgers system with time variable coefficients which arise in engineering, chemistry, chemical physics, plasma physics, complex physics and phenomena gives multiple ... -
Production of metal-oxide nanoclusters using inert-gas condensation technique
