No. of bitstreams: 0 Previous issue date: 2018-01-01; PIBIC (Programa de Iniciacao Cientifica da UNESP); Restaurants produce large-scale meals, generating large amounts of solid waste, which if not properly managed cause environmental and sanitary problems. Composting is one of the most recommended methods for the treatment of organic solid waste, since th...
Oily sludges are hazardous wastes that contain large amounts of hydrocarbons, water and dissolved solids. A simple distillation procedure was used to fractionate this sludge and isolate a gas phase (10%), and an organic liquid phase (30%) that can be used as fuels. This procedure also separates the water phase from the dissolved solids enabling the independent management of those phases with more appropriated m...
The feasibility of using a zinc oxide rich waste (ZnO>95%), dust originated in the brass smelting industrial process, as a raw material to produce targets to be used in radiofrequency magnetron sputtering (RFMS) deposition of ZnO thin films was investigated. The ZnO waste was characterized in terms of chemical and mineralogical compositions and particle size distribution. The targets were prepared by uniaxial p...
The Luiz Bandeira Bridge is located along the Portuguese national road EN333-3, breaching the valley of the Vouga River, just northeast of the small village Sejães, in the district of Oliveira de Frades. It is considered to be the oldest concrete bridge in use in Portugal, and one of the oldest in Europe.
