1. Effects of sintering temperature on microstructure and properties of sanitaryware ceramic produced with waste material
Abstract This paper aims at exploring the possibility of using a great percentage of recycled materials into vitreous china (VC), thus, contributing to urban waste decrease while lowering the industry’s buying costs, previously optimized, for the sanitaryware production. The recycled blend was introduced in the ceramic slip, Sanitser VC, and used in three

2. TECHNICAL AND ECONOMIC FEASIBILITY OF USING A VARIABLE-FREQUENCY DRIVE IN MICRO-IRRIGATION SYSTEMS
ABSTRACT Irrigation is essential for the development of crops in regions with scarcity or irregular rainfall distribution, enabling high productivity. However, the use of water resources and electrical energy leads to a concern with irrigation efficiency. Pressure demand varies during the operations of irrigation systems and the appropriate pressure can be r

3. Strategies used to control the costs of underground ventilation in some Brazilian mines
Abstract In an underground mine, the ventilation is responsible for 25% to 50% of its electrical energy consumption. In countries such as South Africa, United States and Canada researchers have started to achieve a significant reduction in energy consumption without neglecting aspects of the quantity and quality of air required for the best performance of th

6. Evaluation of the Effect of the Incorporation of Blends of Fuel and Fluxing Wastes in Red Clay Ceramics
The clay samples endure the incorporation of industrial and urban wastes, which do not cause large variations in their properties if added in controlled quantities. Wastes can be classified as fuel, fluxing and property affecting wastes. The fuel wastes usually have a high amount of organic matter, that when heated cause exothermic reactions, releasing heat

7. Integrated project of a smart microgrid allied with energy management: An initiative to reduce electrical energy costs
Abstract Electricity is undoubtedly one of the most important resources in the modern world. As the demand for electric energy increases, conventional resources that are transformed into electric energy are being exhausted, generating a need to search for alternative sources, resulting in a significant increase in energy costs. This study presents an integra

9. Assessment of the Potential Implementation of Solar Energy Generation in State Schools in Curitiba/PR
ABSTRACT Solar energy as a form of electric power generation is gaining ground in Brazil, being the subject of worldwide discussions on sustainability. The electric energy, a right of all citizens, represents a consumption of natural resources on a large scale. State schools in Paraná invested more than R$ 46 million to guarantee electricity and thus provid
