OBJECTIVE to evaluate the respiratory status of postoperative adult patients by assessing the nursing outcome Respiratory Status. METHOD descriptive, cross-sectional study developed with 312 patients. Eighteen NOC indicators were assessed and rated using a Likert-scale questionnaire and definitions. Descriptive and correlative analysis were conducted. (More)
In this article, we consider systems of integral-algebraic and integro-differential equations with weakly singular kernels. In the first part, we deal with two-dimensional integralalgebraic equations. Next, we analyze Volterra integral equations of the first kind with a degenerate matrix-kernel on the diagonal. Finally, the third part of the work is devoted(More)
We study the numerical solution of a singular free boundary problem for a second order nonlinear ordinary differential equation, where the differential operator is the degenerate m-Laplacian. A typical difficulty arising in free boundary problems is that the analytical solution may become non-smooth at one boundary or at both boundaries of the interval of(More)
For a second order nonlinear ordinary differential equation (ODE), a singular boundary value problem (BVP) is investigated which arises in hydromechanics and nonlinear field theory when static centrally symmetric bubble type (droplet type) solutions are sought. Being defined on a semi infinite interval 0 < r <∞, this ODE, with a polynomial nonlinearity of(More)
Analytical properties of a nonlinear singular second order boundary value problem in ordinary differential equations posed on an unbounded domain for the density profile of the formation of microscopic bubbles in a nonhomogeneous fluid are discussed. Especially, sufficient conditions for the existence of solutions are derived. Two computational methods, a(More)
