1. Caffeine as a chemical tracer for contamination of urban rivers
RESUMO A crescente urbanização nos grandes centros urbanos têm contribuído de forma contínua na deterioração da qualidade das águas dos corpos hídricos receptores. Uma nova abordagem para monitoramento da qualidade d’água é o uso de cafeína como traçador de atividade antrópica em rios urbanos, uma vez que seu uso é limitado a humanos e sua m

2. Physicochemical, microbiological and parasitological characterization of the filter backwash water from a water treatment plant of Blumenau - SC and alternatives for treatment and reuse
Resumo A água de retrolavagem dos filtros (ARF) de estações de tratamento de água (ETA) é composta por resíduos da água bruta, produtos químicos e microrganismos. Seu descarte inadequado impacta negativamente o meio ambiente e a saúde da população humana. Objetivando caracterizar a ARF da ETA de Blumenau-SC, foram realizadas avaliações físico-q

3. Plumas em escoamento uniforme com estratificação de duas camadas
RESUMO Plumas ocorrem quando um fluido é descarregado em outro fluido com densidade diferente, como poluentes na atmosfera. Neste trabalho, desenvolveu-se um estudo experimental em um tanque de água e modelagem matemática usando a abordagem integral com o intuito de investigar o escoamento gerado por plumas salinas em escoamento uniforme e com estratifica

4. Comparative metagenome of a stream impacted by the urbanization phenomenon
Abstract Rivers and streams are important reservoirs of freshwater for human consumption. These ecosystems are threatened by increasing urbanization, because raw sewage discharged into them alters their nutrient content and may affect the composition of their microbial community. In the present study, we investigate the taxonomic and functional profile of th

5. Alternativas de tratamento da água de lastro em portos exportadores de minério de ferro. / Ballast water treatment alternatives in the iron ore ports exporting.
This thesis aims at making a technical and economic analysis of the ballast water treatment in Brazilian iron ore ports. Three distinct treatment alternatives were studied: (1) onshore ballast water treatment; (2) water desalination plant to ballast water treatment; (3) onboard ballast water treatment in shuttle tanker vessels operating in the mooring, where

6. Avaliação da resistência à compressão e da absorção de água de concretos utilizados após o tempo máximo de mistura e transporte especificado pela NBR 7212 / Evaluation of compressive strength and water absorption of concrete used after the maximum time of mixing and transport specified by NBR 7212
The Brazilian standard NBR 7212 (ABNT, 1984), for execution of ready-mixed concrete, specifies the maximum time for concrete to be discharged (used) completely in 150 minutes. The usage time of the concrete is due to reactions of the cement hydration and slump loss that occurs with fresh concrete, a normal phenomenon defined as the loss of fluidity along the

7. Software para definiÃÃo e avaliaÃÃo de unidades de manejo em Agricultura de precisÃo / Software for definition and evaluation of management zones in Precision agriculture
Water and soil conservation is essential for water resources management. Thus, conservationist actions are developed and applied in order to make part of a set of measures which enable the supply management, based on an appropriate recharge of the aquifers as well as the improvement of their quality, from the reduction of erosive processes and volume of effl

8. Avaliação da utilização de colifagos como indicadores virais a partir da análise de enterovírus e adenovírus em efluentes tratados por diferentes processos biológicos
Domestic sewage contains a high amount of bacteria and other pathogens and non pathogens that are discharged into water bodies. Contamination of water by the presence of pathogenic bacteria and viruses, brings undesirable consequences, especially for public health. The objective of this work was to evaluate the possibility of using analysis of coliphages as

9. Emprego da técnica de emissão por fluorescência de ultravioleta no monitoramento de inibidores de corrosão em água produzida / Use of ultraviolet fluorescence emission in the monitoring of corrosion inhibitor in produced water
In order to increase the volume of oil extraction, solve and prevent problems in oil production, several chemical products are used. Corrosion inhibitors are the main chemical products used in the whole oil production chain, whose objective is to protect the system from deterioration caused by corrosion. The quaternary ammonium salts are the kind of inhibito

10. Toxicity and genotoxicity of wastewater from gasoline stations
The toxicity and genotoxicity of wastewater from eight gasoline stations in Brasília, Brazil's capital city, was studied by assessing chromosomal aberrations, chromosomal malsegregation and the mitotic index in Allium cepa root cells, and the occurrence of micronucleus and nuclear abnormalities in peripheral erythrocytes of tilapia fish (Oreochromis nilotic

11. Tratamento de esgoto sanitario em reator anaerobio preenchido por casca de coco verde (Cocos nucifera) combinado com filtro de areia / Wastewater treatment through an anaeroboc filter filled up with coco nuts (cocos nucifera) combined with sand filter
The development of efficient wastewater treatment systems, which are also adapted to the economic and structural conditions of a village, would be an option to decrease the lack of water problem since the effluent could be reused or discharged into receiving waters. Moreover, with wastewater system, health and environmental problems would be less frequent. F

12. Avaliação da qualidade do Rio São Lourenço, SP, sob influência de estações de tratamento de água e estações de tratamento de esgoto / ENVIRONMENTAL QUALITY IN AREA OF INFLUENCE OF MUD OF STATIONS FOR TREATMENT OF WATER AND SEWAGE
For a long time, there was a neglect to water resources, both by society as by the authorities. The rapid increase of population, causing disorderly occupations, was ignored by the public sectors and the society itself, resulting in environmental degradation. Ecotoxicological tests are essential to environmental assessment, together with chemical and biologi
