13. NUMERICAL MODELLING OF INFILTRATION OF HYDROCARBONS IN UNSATURATED SOILS USING THE FINITE VOLUME METHOD / MODELAGEM NUMÉRICA DA INFILTRAÇÃO DE HIDROCARBONETOS EM SOLOS NÃO SATURADOS UTILIZANDO O MÉTODO DE VOLUMES FINITOS
A large proportion of the population depends on groundwater for consumption. Thus, leakage of gasoline tanks represents a significant risk to public health besides the risk of fire and explosion in the sewer lines, due to the flammable gases. These tanks are generally located in the unsaturad soil above the groundwater level. It is therefore important to eva

14. Development and application of low trans fat in margarine and plain cake. / Desenvolvimento e aplicação de gorduras low trans em margarina e bolo tipo ingles.
Trans fatty acids (TFA) present in diet come mainly from the partially hydrogenated fats and a lower amount from the refined oils, meat and ruminant animals? milk. Some studies show that TFA consumption leads to an increase in low-density lipoprotein (LDL) as much as that caused by saturated fatty acids and decrease in high-density lipoprotein (HDL). Hence,

15. 3D OPACITY IN VOLUME RENDERING OF SEISMIC DATA / OPACIDADE 3D NA VISUALIZAÇÃO VOLUMÉTRICA DE DADOS SÍSMICOS
This work proposes a 3D opacity technique for the volume rendering of seismic data. The greater challenge of volume rendering is to define a multidimensional transfer function better adapted to the data to be visualized. This work presents a transfer function that uses three 1D color tables to compose a 3D color table. The work from Silva[30] about 2D opacit

16. Modelagem espaço-temporal regionalizada de alturas de lençol freático no cerrado brasileiro / Regionalized spatio-temporal modelling of water table depths in the brazilian cerrado
Regimes hídricos governados pela sazonalidade são sensíveis a distúrbios climáticos e intervenções humanas Os Cerrados brasileiros são caracterizados por uma estação seca bem pronunciada, de maio a setembro. Durante esse período a vegetação natural e os campos agrícolas são dependentes da água subterrânea. A vegetação dos Cerrados é adapt

18. Study on the application of microwaves to the drying of osmotically treated bannanas. / Estudo da aplicação de microondas na secagem de bananas tratadas osmoticamente.
Brasil is one of the largest banana producer in the world, with the crop being predominantly consumed in the internal market, as table in natura fruit and as processed foods. The implementation of methods to transform such a raw material becomes attractive as long as it takes advantage of the production surplus, reduces the crop wastes and allows aggregating

19. Estimating the drainable porosity using different methodologies / Estimativa da porosidade drenável por diferentes metodologias
This study had as its objective to estimate the drainable porosity through different methodologies. Four methods were utilized: the first one was based upon the water table drawdown in a soil filled tank; the second one based upon the Van Beers empirical equation, the third one through the ABNT recomendation, and the last one based upon the water release cur

20. Natural attenuation of gasoline and ethanol ground water plume / Atenuação natural de pluma de contaminação de gasolina e etanol em água subterrânea
A case study and two controlled field experiments were conducted to evaluate the impact of ethanol on the natural attenuation processes affecting dissolved phase of gasoline plumes. The case study was conducted in Itaguaí (RJ) where an E22 (gasoline with 22 % by volume of denatured ethanol) contaminant plume was studied. The controlled field experiments wer

21. Processamento e interpretação de dados 2D e 3D de GPR :aplicações no imageamento de feições kársticas e estruturas de dissolução no campo de petróleo de Fazenda Belém-CE
In Fazenda Belém oil field (Potiguar Basin, Ceará State, Brazil) occur frequently sinkholes and sudden terrain collapses associated to an unconsolidated sedimentary cap covering the Jandaíra karst. This research was carried out in order to understand the mechanisms of generation of these collapses. The main tool used was Ground Penetrating Radar (GPR). Th

22. Avaliação da aderência dos revestimentos argamassados: uma contribuição à identificação do sistema de aderência mecânico
The evaluation of finishing coat of mortar in the construction practice is commonly carried out by a macroscopic approach. However, for a better understanding of the several mechanisms related to mortar characterization and performance a microstructure assessment on these materials is necessary. The adherence of a mortar to the substrate proceeds by mechanic

23. CRESCIMENTO E PRODUÇÃO DE TECTONA GRANDIS LINN F., EM POVOAMENTOS JOVENS DE DUAS REGIÕES DO ESTADO DE MATO GROSSO - BRASIL / GROWTH AND YIELD OF TECTONA GRANDIS LINN F. FOR THE STATE OF MATO GROSSO BRAZIL
The Tectona grandis Linn F. was introduced in Mato Grosso in the end of the sixties and new planting is made each year in the State with the aim of replacing native woods of noble use. Beyond the expectation of great future gains the teak plantations are, most of the time, made in the mosaic system. This system is certainly the greatest advantage of this woo

24. Gerenciamento de resíduos laboratoriais: recuperação de elementos e preparo para descarte final
This work shows some laboratory waste management developed in order to recover some elements or to prepare the waste for a correct final disposal. The 25 elements chosen cover basically all chemical behaviors found for the metals in the Periodic Table. The treatments adopted were based on the classical behavior in aqueous solution (wet chemistry) but an impo
