15. Uso de agregados reciclados de concreto em blocos de alvenaria estrutural / Use of recycled concrete aggregates in blocks of structural masonry
The main goal of the present research project was the evaluation of recycled concrete aggregates incorporation in structural concrete blocks of three different levels of compressive strength (4,5 MPa, 8,0 MPa and 12,0 MPa). The study was developed in four stages. The first stage analyzed the physical properties of fine and coarse concrete aggregates derived

16. Desenvolvimento e análise de uma fornalha para aquecimento direto e indireto de ar utilizando biomassa polidispersa / Development and analysis of a furnace for both direct- and indirect air heating by using polydispersive biomass
A heat-generation system with option to direct or indirect heating of the air, that could be used in drying agricultural products or heating zootechnical facilities was developed and evaluated. The developed furnace has a heat changer with concentric countercurrent-flux tube, and it was fed polydispersive biomass by pneumatic transport or manually with bioma

17. Influência do alimentador de sólidos na fluidodinâmica do transporte pneumático.
Pneumatic transport is an operation where powdery and granular materials are conveyed through a pipeline suspended in a gas flow. It is usually found in several industries segments and it is used as a carrier, such as, in beans production; drying operation, like grain dryers; or as reactors, in cracking catalytic reactions, combustion operations and precalci

19. Altenative analytical methods to quality evaluation of forages used in animal nutrition / Métodos analíticos alternativos para avaliação da qualidade de forrageiras utilizadas na nutrição animal
Alternative methods were developed for some determinations performed in routine by animal nutrition laboratories, in order to increase laboratory efficiency and reduce costs maintaining analytical quality. In the first step, a multicomutation point to point potentiometric titration system to total acid in silage extracts with the use of a PVC (tridodecilamin

21. Study of method to characterize the physical properties of construction and demolition waste coarse aggregates. / Estudo de métodos para caracterização de propriedades físicas de agregados graúdos de resíduos de construção e demolição reciclados.
The low consumption of Construction and Demolition Waste (CDW) recycled aggregates happens, nowadays, because its natural variability and quality control absence that limit its use in applications with larger demands, such as concretes. One way of concrete aggregates control is done by determining its porosity, express by physical properties absorption and r

23. Energy and economic evaluations of systems of production of mountain coffee / Avaliações energética e econômica de sistemas de produção de café de montanha
Para garantir altos níveis de qualidade ao café é necessário usar uma série de procedimentos, como Boas Práticas Agrícolas (BPA), Boas Práticas de Pré-Processamento e Boas Práticas de Processamento (BPP). As definições e aplicações dessas práticas devem ser adotadas em toda a cadeia de produção do café, para transformar o agronegócio em um

24. Kinetics of helminth eggs inactivation in water and digested sludges by saturated steam produced with methane from anaerobic digestors. / Inativação térmica de ovos de helmintos em água e em biossólidos digeridos: cinética em reator batelada e modelagem matemática em reator tubular.
Biological sludge can be a valuable resource for agricultural soil conditioning. However, an important obstacle for its use is the usual presence of pathogenic organisms, capable of disease dissemination. The main occurring pathogens are virus, bacteria, protozoa and helminth. Helminth eggs are very resistant to thermal inactivation. The Ascaris lumbricoids
