OBJECTIVE The use of colonoscopy as a primary screening test for colorectal cancer (CRC) in average risk adults is a subject of controversy. Our primary objective was to build a predictive model based on a few simple variables that could be used as a guide for identifying average risk adults more suitable for examination with colonoscopy as a primary(More)
In this work, we study the convergence of the finite element method when applied to the following parabolic equation: u t = div(|u| γ(x) ∇u) + λ|u| σ(x,t)−2 u + f (x, t), x ∈ Ω ⊂ R d , t ∈]0, T ]. Since the equation may be of degenerate type, we utilize an approximate problem , regularized by introducing a parameter ε. We prove, under certain conditions on(More)

Since the problem may be of degenerate type, we utilize an approximate problem, regularized by introducing a parameter ε. We prove, under certain conditions on γ and f , that the(More)
