1. The bounded solutions to nonlinear fifth-order differential equations with delay
In this paper, we improve some boundedness results, which have been obtained with respect to nonlinear differential equations of fifth order without delay, to a certain functional differential equation with constant delay. We give an illustrative example and also verify our main result by means of Liaponov tecnique.

2. Immune response mathematical model to HIV virus infection. / Modelo matemático da resposta imune à infecção pelo vírus HIV-1.
Avanços recentes nos conhecimentos sobre a infecção viral e AIDS tem levado pacientes soropositivos a uma melhor qualidade de vida. A determinação de quais populações celulares ou qual mecanismo imunológico seja mais relevante para instalação da epidemia conduz a novos patamares de possibilidades de novas drogas antiretrovirais e tratamento mais ef

3. Further developments in unsteady compressible vortex lattice method in two dimensional motion.
Unsteady phenomena like flutter, buffeting, rapid maneuvers in flight and gust entry are usually modeled and studied by a theoretical treatment involving potential flow methods. The resulting equation from this approach is the governing differential equation for general non-steady, non-viscous, potential flow known as convected wave equation. The disturbance
