"For example, we referred Celeste to the local health centre for anti-retroviral treatment, and she is doing well now," she said.
For example, we referred to patients' "poor patient-physician relationship" rather than the more encompassing "dislike of the provider" [ 13] because these patients stressed the characteristics of the relationship, rather than an overall and imprecise dislike of the provider.
In recent years, the solvability of the antiperiodic boundary value problems of first-order and second-order differential equations were studied by many authors, for example, we refer to [20 32] and the references therein.
In some special cases, when the nonlinear term has various forms, the following nonlinear wave equation u_{tt}-Delta u=F x,t,u,u_{t}), (1.4) where Δ is a Laplace operator, has been extensively studied by many authors, for example, we refer to [1 10] and the references given therein.
The wave equation u_{tt}-Delta u=f x,t,u,u_{t}), (1.4) with different boundary conditions, has been extensively studied by many authors, for example, we refer to [1 25] and the references given therein.
For example, we refer the reader to [1, 2] and the references cited therein.
Equation (1.3) has been studied extensively by many authors, and there is a large body of literature on the existence and multiplicity of results of solutions for equation (1.3); for example, we refer the readers to [1 3] and references therein.
For example, we refer the reader to [1 6] and the references cited therein.
For example, we refer the reader to monographs [2, 3] and the references therein.
For example, we refer the reader to [3 6] and the references therein.
In the last few decades, many authors have researched various generalizations of the Gronwall-Bellman inequality; for example, we refer the reader to [3 28] and the references therein.
