Wrapping Effect

Tool presentation: We present work in progress on a stand-alone implementation of Lagrangian reachability, a recently introduced over-approximation technique for nonlinear continuous systems. Unlike the previous prototype, the current implementation does not depend on the over-approximation tool CAPD, and invokes an improved Lohner’s QR method to tame the infamous wrapping effect.

This paper gives the first results of a work in progress, in collaboration with G. Michaud and G. Vauclair. It is a first attempt to compute the effects of meridional circulation and turbulence on diffusion processes in stellar envelopes. Computations have been made for a 2 Mʘstar, which lies in the Am - δ Scuti region of the HR diagram.Let us recall that in Am stars diffusion cannot occur between the two outer convection zones, contrary to what was assumed by Watson (1970, 1971) and Smith (1971), since they are linked by overshooting (Latour, 1972; Toomre et al., 1975). But diffusion may occur at the bottom of the second convection zone. According to Vauclair et al. (1974), the second convection zone, due to He II ionization, disappears after a time equal to the helium diffusion time, and then diffusion may happen at the bottom of the first convection zone, so that the arguments by Watson and Smith are preserved.

Level Of Understanding

Abstract Response to Intervention (RTI) implementation is becoming more widespread due to the references of RTI components in the Federal Regulations. But everyone is not at the same level of understanding about RTI and its implementation. This article will answer several questions. What is RTI? Why are we hearing more and more about RTI? How are states implementing RTI components? How can the speech-language pathologist help in RTI implementation in the presence or absence of a specific RTI infrastructure? How is Florida Proceeding with RTI implementation? Are there any new resources available for principals and other educators who might want to learn more about RTI?
