The Use Of Physical Restraint: An Argumentative Essay

This study was conducted to review the literature about the use of physical restraints as an argumentative issue. The use of physical restraints has been reported with varying prevalence from 41% to 64% according to epidemiological studies. In this study, the author reviewed the opinions of the opponent and proponent viewpoints regarding physical restraints from legal and ethical perspectives. The ideas of proponents implied that the use of physical restraints offers protection for patients and others as well as ensures introducing good treatment. On the other hand, the opponents think that the use of physical restraints is not well safe and associated with legal and ethical issues. Furthermore, psychological injuries and mental problems have been reported to be associated with the use of physical restraints. The author agrees with the opponents and does not support the use of physical restraints because it involves ethical, legal and health impacts

Variable order Mittag-Leffler fractional operators on isolated time scales and application to the calculus of variations

We introduce new fractional operators of variable order on isolated time scales with Mittag-Leffler kernels. This allows a general formulation of a class of fractional variational problems involving variable-order difference operators. Main results give fractional integration by parts formulas and necessary optimality conditions of Euler-Lagrange type.Comment: This is a preprint of a paper whose final and definite form is with Springe

Razumikhin Stability Theorem for Fractional Systems with Delay

Fractional calculus techniques and methods started to be applied successfully during the last decades in several fields of science and engineering. In this paper we studied the stability of fractional-order nonlinear time-delay systems for Riemann-Liouville and Caputo derivatives and we extended Razumikhin theorem for the fractional nonlinear time-delay systems

Time-Fractional Optimal Control of Initial Value Problems on Time Scales

We investigate Optimal Control Problems (OCP) for fractional systems involving fractional-time derivatives on time scales. The fractional-time derivatives and integrals are considered, on time scales, in the Riemann--Liouville sense. By using the Banach fixed point theorem, sufficient conditions for existence and uniqueness of solution to initial value problems described by fractional order differential equations on time scales are known. Here we consider a fractional OCP with a performance index given as a delta-integral function of both state and control variables, with time evolving on an arbitrarily given time scale. Interpreting the Euler--Lagrange first order optimality condition with an adjoint problem, defined by means of right Riemann--Liouville fractional delta derivatives, we obtain an optimality system for the considered fractional OCP. For that, we first prove new fractional integration by parts formulas on time scales.Comment: This is a preprint of a paper accepted for publication as a book chapter with Springer International Publishing AG.
