Fuels such as biodiesel have been gaining popularity as an alternative fuel. The study deals with the evaluation of the performance and emissions of a generator engine operating with diesel and biodiesel blends, assisted by an industrial automation system used in Industry 4.0. The experiment was carried out in the laboratories of the State University of West Paraná. The energy generated, the specific consumptio...
In the breeding of broiler house, the proper use of lighting systems has great influence on the welfare and the productivity of the birds. The objective was to evaluate two artificial lighting systems used in broiler house in terms of the allocative efficiency of luminance. One of the broiler house was closed with black raffia bag (dark house), without thermal insulation (NTI) and its lighting was composed of i...
Atrazine is a herbicide widely used in control of predominant broad leaf infestations in agricultural crops such as corn, sorgo and sugarcane, with high mobility in the soil, and may become toxic to aquatic organisms, plants and humans. Thus, the adsorption of pesticides by biocoals becomes a viable option, mitigating the environmental impacts caused. Used in physico-mathematical models, ion leaching tests in s...

No. of bitstreams: 0 Previous issue date: 2020-03-01; In this work, two effective ways for reducing the acidity of raw materials aimed to biodiesel production were tested, one being the neutralization and other the esterification of free fatty acids. Residual chicken fat and waste cooking oil were tested, since both are generated in large volumes, however ...
O presente trabalho teve por objetivo realizar o processo de biodigestão anaeróbia de material plástico polimérico biodegradável à base de fécula de mandioca, utilizando-se de biodigestores de escala laboratorial com modo de operação batelada. Utilizou-se água residual estabilizada de suinocultura como matéria-prima e copos plásticos biodegradáveis produzidos a partir de fécula de mandioca para a produção de bi...
Este estudo teve como objetivo realizar processo de co-digestão anaeróbia da vinhaça, oriunda dos processos de produção do etanol hidratado, e dos resíduos de suinocultura. Utilizaram-se biodigestores tubulares sob diferentes condições de temperatura e avaliaou-se a eficiência na remoção de sólidos, demanda química de oxigénio (DQO) e a produção de biogás. Para isso utilizaram-se dois reatores, sendo um deles c...
Urbanization and disorderly occupation of urban areas have created several environmental problems, such as floods. Among the main causes of these problems is soil sealing associated with urban sprawl. Impervious surfaces provide less precipitation to recharge catchment basins by diverting water that should be restored in that region to other basins. This study compares two existing paving systems: concrete pave...
