1. Tipos e eficiência de unidades de tratamento para água pluvial: revisão de literatura
Resumo O aproveitamento de água pluvial em edificações representa uma alternativa atraente como fonte de água. No entanto, para possibilitar sua utilização, a água pluvial deve ser tratada para atingir a qualidade necessária. Os filtros são bastante utilizados e aparecem em diversos modelos. Com o intuito de avaliar diferentes sistemas de filtragem,

3. Anaerobic bio-digestion of concentrate obtained in the process of ultra filtration of effluents from tilapia processing unit
The objective of the present study was to evaluate the efficiency of the process of biodigestion of the protein concentrate resulting from the ultrafiltration of the effluent from a slaughterhouse freezer of Nile tilapia. Bench digesters were used with excrements and water (control) in comparison with a mixture of cattle manure and effluent from the stages o

4. Estudo do processo de calcinação como operação unitária adicional na pelotização de minérios de ferro com altos valores de PPC
The mineral resources from the Alegria complex, at the Mariana Ouro Preto/MG region, where Samarco´s deposits (Alegrias Norte, Centro and Sul) are located, present a significant parcel of composition related to low iron grade itabirites (below 50%) and high LOI contents (above 3.5%). The search for producing concentrates from these deposits using the curren

5. Removal of helminth eggs in sewage side, through rapid sand filters, anthracite coal and zeolite for agricultural reuse and urban non-potable. / Remoção de ovos de helmintos de esgotos secundários, por meio de filtros rápidos de areia, carvão antracitoso e zeólito para reúso agrícola e urbano não potável.
Helminth eggs are one of the major problems regarding the reuse of treated sewage in agriculture and non-potable urban irrigation since both workers who handle the effluent and the consumer population might become contaminated. Helminth eggs are not efficiently removed by conventional unit operations and processes, which do not allow the removal of helminth

6. Cultivares, variaves de processo, reuso do xarope de sacarose e viabilidade economica da pre-secagem osmotica de pessegoa / Cultivars, process variables, reuse syrup and economicv feasibility of the osmotic pre-driyng of peaches
The objective of the present study was to evaluate the industrialization of peach cultivars from the State of São Paulo, Brazil, in the semi-dried form, using a combined process involving osmotic pre-drying (OPD) and conventional hot air drying (CD). The aptness of the cultivars Douradão, Régis, Aurora-1 and Diamante was evaluated, using OPD with sucrose

7. Desempenho da Tecnologia de Filtração em Múltiplas Etapas (FiME) no Tratamento de Águas de Abastecimento em Escala Piloto / Performance technology Multi-Stage Filtration (MSF) for supplying water treatment on a pilot scale
The present work has evaluated the efficiency of an MSF system for treating supplying water on a pilot scale. A MSF pilot plant was located in the Water Treatment Station (WTS) area in Goianápolis- GO and fed by Sozinha stream. The plant was comprised of a dynamic prefilter (DPF) and a vertical upflowing pre-filter (VUF) in layers, both of them with differe

8. Study of reuse and recycling of rapid filter backwash water from water treatment plant in independent close cycle system / Estudo de reuso e reciclagem de agua de lavagem de filtro rapido de estação de tratamento de agua, em sistema de ciclo fechado, independente
The project was developed with the aim of studying the treatment and the reuse of rapid filter backwash water for recycling in this role, within a closed cycle, under system independent of production activities of a water treatment plant. The system was assembled with a polymer blending unit, a gravel preliminary upflow filter and a dual layer filter(F3), si

9. X-ray beam qualities for dental radiology purposes / PadronizaÃÃo de qualidade de feixes de raios-X para uso em radiologia odontolÃgica
In order to establish characteristics or properties of equipment for diagnostic radiology, e.g. ion chambers and semiconductor detectors, calibration laboratories offer a set of well-defined radiation conditions, called X-ray qualities, which can be used for many Physics studies and medical purposes. These X-ray qualities can be determined in terms of: (a) X

11. Post-treatment of effluents from anaerobic reactor treating domestic sewage by flotation/filtration pilot system with cationic synthetic polymers / Emprego de polímeros em unidade piloto de floto-filtração como pós-tratamento de efluentes de reatores anaeróbios de leito expansível tratando esgoto sanitário
This work assessed the performance of domestic sewage treatment pilot unit consisting of anaerobic reactor followed dissolved-air flotation/filtration (DAFF). Associated ferric chloride was used polyelectrolytes. First, was tested in lab-scale dissolved-air flotation (LSDAF), low dosages of cationic synthetic polymer with high molecular weight as aiding of f

12. Mecanismos de defesa comportamental e anatômico contra doenças e ectoparasitas em abelhas africanizadas (Apis mellifera) / Behavioural and anatomic defense mechanisms against diseases and ectoparasites in Africanized honey bees (Apis mellifera)
This study was conducted to select Apis mellifera colonies for diseases and ectoparasites tolerance and to investigate characters of proventriculus that confer protection against pathogens. Colonies in the region of Viçosa, Minas Gerais, Brazil, were evaluated for hygienic behavior using pin-killer brood and levels of infestation by Varroa destructor on bro
