Estimation of the collective ionizing dose in the Portuguese population for the...
Costa, F.; Teles, P.; Nogueira, A.; Barreto, A.; Santos, A.I.; Carvalho, A.; Martins, B.; Oliveira, C.; Gaspar, C.; Barros, C.; Neves, D.; Costa, D.Objectives: In 2009-2010 a Portuguese consortium was created to implement the methodologies proposed by the Dose Datamed II (DDM2) project, aiming to collect data from diagnostic X-ray and nuclear medicine (NM) procedures, in order to determine the most frequently prescribed exams and the associated ionizing radiation doses for the Portuguese population. The current study is the continuation of this work, altho...

Existence result for a third-order ODE with nonlinear boundary conditions in pr...
Grossinho, Maria do Rosário; Minhós, F.M.; Santos, A.I.In this work we provide an existence and location result for the third-order nonlinear differential equation... We assume that f satisfies a sign-type Nagumo condition which allows an asymmetric unbounded behaviour on the nonlinearity. The arguments used concern Leray–Schauder degree theory and lower and upper solutions technique.
