BACKGROUND Augmentative and Alternative Communication (AAC) is expanding in our country, however it is still not a widely recognized practice. Although the term 'Augmentative and Alternative Communication' is well defined in the international literature, in our country there is no official and/or accepted version. AIM To review the terms used in Brazil and to discuss their implications, takin...

This paper proposes monolithic and partitioned methods to calculate the static deformation of a membrane structure due given volume ponding water. The involve coupling structural solver for membranes volume-conserving solver, modeling incompressible fluid. Two this type are proposed, either using iterations with convergence accelerator between or adding linearized fluid behavior in addition ext...

N,N-dimethyltryptamine, or DMT, is an endogenous psychoactive chemical that has been shown through repeated human subject experimentation to provide the subject with a perception of an 'alternate reality'. When administered a sufficient DMT dose, subjects have reported the presence of intelligent beings that do not appear to be the projections of their subconscious in the Freudian sense. Furthe...

Methods which can be used to assess the chloride permeability of various types of concrete in a relatively short time are described. An electrical potential from 60-80 volt DC is applied either between a chloride solution ponded on a slab surface and the top of rebar mat, or between two faces at a core taken from a structure. The amount of chloride and sum of the electrical current which passes...

The metabolism, both in vitro and in vivo, of the chiral isomers of the phosphonodithioate insecticide fonofos was examined. The absolute configurations of the fonofos isomers and relevant oxidation products were established by x—ray diffraction analysis and chemical correlation. Oxidation of fonofos to the corres— ponding oxon in the presence of mouse liver mixed—function oxidase occurred pred...
