This work analyses the recuperation of the energy of Municipal Solid Waste (MSW) through the incineration process. It considers the up to date tendency of segregation (separation) of plastic, paper and cardboard, glass and metals and their influence in the fluxes of mass and energy in the incineration system of MSW. For its development was used information related to the generation of MSW in Bauru city and the Combust software. The results so obtained allowed the estimation of the Caloric power of the typical MSW and also of this residue when one considers the separations of paper/cardboard and plastic for recycling.

This work discusses the design of flexible pavements for airports, with the aid techniques and tools necessary for the calculation and design critical aircraft as the Boeing 777-300ER. Also discussed the layers that make up the pavement, the materials used and the method used for design pavement (FAA method)

The main purpose of this research is to raise, through lab rehearsals, the geometric properties of some oxisols from the region of Vale do Paraíba as well as comparing them to demands prescribed by Technical Specifications ESP08/05 of the Road Department of the State of Paraná, for sub-base or fine grained lateritic soil base (SAFL) and in the Technical Specification ET-DEP00/006 of the Road Department of the State of São Paulo (DER/SP) for subbase or crushed stone base. According to the results that were obtained it will be feasible to appraise the usage of these sorts of soils in structure layers of low-weight traffic pavements

This work has as objective, show and compares some of several evaluation methods of pavements, based in the rules and researches realized by another authors, with focus on low traffic volume pavements, which are generally more economic flexible pavements subjected to low loads. Were addressed structure evaluation methods and superficial evaluation methods applied to that kind of pavement, exposing of clearly the procedures to be performed, the advantages and disadvantages, as well the results obtained in the execution of each one of these. This theme was chosen by the widespread use of this type of pavement in the road network of the country and the fact that there is no still a culture of the practical of evaluation nor technical knowledge on the part of municipal governments that are usually responsible for these roads. This study also aims to guide the process of maintenance preventive or recuperative, as they are often made improvements that do not actually solve the real problem of the roads

Tempestitos grossos constituem camadas delgadas de conglomerado gradando a arenito, com estratificação cruzada seguida de laminação ondulada truncante a simétrica e de drape/flaser de siltito/folhelho. Cinco exemplos extraídos do Permiano da bacia do Paraná ilustram esse tipo de depósito: três deles são de rochas siliciclásticas, contendo bioclastos de bivalves e vertebrados (Formação Rio Bonito-Membro Triunfo e Formação Palermo), enquanto os outros dois são de rochas carbonática e fosfática (respectivamente, formações Teresina e Corumbataí do Grupo Passa Dois). O componente tracional da base do tempestito grosso apresenta-se como arenite quartzoso/lítico ou grainstone oolítico com cimento calcífero preenchendo poros (casos das formações Palermo e Teresina). em sua maioria, os tempestitos grossos constituem pavimentos transgressivos intercalados em folhelhos ou tempestitos finos (arenitos muito finos a folhelhos com estratificação ondulada truncante-hummocky). em outro caso, extraído de subsuperfície, o pavimento transgressivo ocorre na base de uma sucessão progradante de barra de plataforma. O tempestito grosso da Formação Teresina constitui um evento transgressivo sobreposto a depósitos de barra de plataforma.
