1. Investigation of Distribution of Antioxidant Compounds from Natural Sources and Study of Lipid Protection in Oil-in-Water Emulsions
The investigation of the distribution of antioxidant compounds between emulsions phases, employing natural sources of these compounds directly in the emulsions, is rarely addressed. The use of ultra performance liquid chromatography coupled to a mass spectrometer (UPLC-MS), combined with accelerated oxidation tests and oxygen radical absorbance capacity meth

2. ESTUDO COMPARATIVO ENTRE EXTRAÇÃO SOXHLET E ULTRASOM PARA DETERMINAÇÃO DE HIDROCARBONETOS POLICÍCLICOS AROMÁTICOS EM SEDIMENTOS DO ESTUÁRIO DO RIO SERGIPE POR CROMATOGRAFIA A GÁS ACOPLADA A ESPECTROMETRIA DE MASSAS. / COMPARATIVE STUDY OF EXTRACTION SOXHLET AND ULTRASOUND DETERMINATION FOR OIL POLYCYCLIC AROMATIC SEDIMENTS SERGIPE RIVER ESTUARY BY GAS CHROMATOGRAPHY MASS SPECTROMETRY ATTACHED.
Polycyclic aromatic hydrocarbons (PAHs) are compounds that can be found in environmental compartments such as atmosphere, soil, sediment and water. Throughout bioaccumulation, they can also be incorporated into vegetables and animals tissues. They are mainly originated from anthropogenic sources such as fossil fuels and biomass burnings. Due they potential t

4. Impacto das Áreas de Preservação Permanente sobre a erosão hídrica na bacia hidrográfica do Rio da Prata, Castelo-ES / Impact of Permanent Preservation Areas on water erosion in the watershed of River Silver, Castelo-ES
A watershed is the primary unit of water resource management, because their behavior affects the hydrological occurrence and magnitude of water erosion. Hydrologic simulation models, which allow to estimate the hydrology and water erosion, consisting of important management tool to minimize environmental degradation in these units. The Permanent Preservation

5. Avaliação quantitativa do risco microbiológico em águas e biossólidos: estado da arte / Quantitative microbial risk assessment: state of the art in water and biosolids
The quantitative microbial risk assessment is the process used to estimate the probability of infection, disease or death after exposure to pathogenic microorganisms present in water, biosolids, food and air. This research aims to describe the state of the art of quantitative microbial risk assessment associated with water and biosolids, and to describe the

6. Metais pesados e micronutrientes no solo e em folhas de Brachiaria decumbens às margens de rodovias / Heavy metals and micronutrients in soil and in leaves of Brachiaria decumbens on the margins of highways
The generation of various wastes, has become alarming in light of their growing volume and their disposal to form inappropriate, especially in soil. One of the characteristics of such waste is the possibility of being contaminated by heavy metals. The Fuel obtained the refining of oil, widely used in automobiles, are usually enriched with toxic elements. The

7. Gestão de pessoas em sistemas de tratamento de água
The production of drinking water according to hygiene standards is an essential activity within the municipality. Thus, it must be properly managed in order to ensure the quality of the final product. The Water Treatment Systems (SiTAs) face many problems concerning production activities, such as inadequate dosage of chemical products, water and energy loss,

8. AvaliaÃÃo das concentraÃÃes de elementos quÃmicos nos sedimentos de fundo do estuÃrio do Rio Formoso (PE)
The estuary of Formoso river is located in the south coastal zone of the Pernambuco state, in an environmental protection area, named APA of Guadalupe. This is an important coastal ecosystem with a rich biodiversity, which plays an important socioeconomic role for the local population. Anthropogenic activities such as shrimp farming, sugar cane cultivation,

9. Hydrological potential of the Monte Olimpo watershed on Campus Luiz de Queiroz of the University of São Paulo / Potencialidades hídricas da microbacia hidrográfica do córrego do Monte Olimpo no campus "Luiz de Queiroz" da Universidade de São Paulo
The goal of this work was to study the hydrological potential of the Monte Olimpo Watershed on Campus Luiz de Queiroz of the University of São Paulo. This watershed is located entirely on the Campus, where good water quality can be stored in two reservoirs. Due to the lack of soil conservation practices and environment concerns this watershed is much degrad

11. FLUX AND TRANSPORT STUDY OF PURE GASOLINE AND GASOLINE BLENDED ETHANOL IN UNSATURATED POROUS MEDIA / ESTUDO DO FLUXO E TRANSPORTE DE GASOLINA PURA E MISTURADA COM ETANOL EM MEIOS POROSOS NÃO SATURADOS
The subsurface release of water immiscible pollutants (NAPLs) due to leaks in storage tanks or pipelines and spilling transportation accidents is of great concern, since the NAPL or its constituents may migrate through the vadose zone until reaching the water table and eventually contaminate clean water sources. In Brazil, most of the gas stations store etha
