Spectral analysis and limit behaviours in a spring-mass system

We consider a model for a damped spring-mass system that is a strongly damped wave equation with dynamic boundary conditions. In a previous paper we showed that for some values of the parameters of the model, the large time behaviour of the solutions is the same as for a classical spring-mass damper ODE. Here we use spectral analysis to show that for other values of the parameters, still of physical relevance and related to the effect of the spring inner viscosity, the limit behaviours are very different from that classical ODE

Iowa’s Title V Block Grant Executive Summary, 2013

Title V of the Social Security Act is the longest-standing public health legislation in American history. Enacted in 1935, Title V is a federal-state partnership that promotes and improves maternal and child health (MCH). According to each state’s unique needs, Title V supports a spectrum of services, from infrastructure building services like quality assurance and policy development, to gap-filling direct health care services. Title V resources are directed towards MCH priority populations: pregnant women, mothers, infants, women of reproductive years, children and adolescents and children and youth with special health care needs.
