14. "Metodologia para Determinação de Hidrocarbonetos Policíclicos Aromáticos em Sedimentos e Solos Periféricos à Represa São Pedro Juiz de Fora, MG"
Polycyclic Aromatic Hydrocarbons are important substances that are produced by many antropogenic sources, among that, the most significant is burns of fossil fuels and biomass which releases these compounds to the environment. Sediments and soils are important matrix to study contamination and their effects because they are able to adsorb organic compounds s

15. Association study between a genetic polymorphism in aldosterone sinthase and resistance to anti-hypertension treatment / Estudo de associação entre polimorfismo no gene da aldosterona sintase e resistencia ao tratamento anti-hipertensivo
Introduction: Resistant hypertension is characterized by elevated blood pressure concurrent with the use of 3 different anti-hypertensive drugs, being one of them a diuretic. There are genetic factors that interfere in the arterial pressure control system and may have a significant role in resistant hypertension. Renin-Angiotensin-Aldosterone System plays a

16. Comparison between PSA density, free PSA percentage and PSA density in the transition zone in the detection of prostate cancer in patients with serum PSA between 4 and 10 ng/ml
OBJECTIVE: Compare the capacity of the PSA density (PSAD), Free PSA percentage (%FPSA) and PSA transition zone density (PSATZ) in improving the sensitivity and specificity of the PSA to detect prostate cancer (PCa) in men with a PSA between 4 and 10 ng/mL. MATERIALS AND METHODS: One hundred and forty five men with PSA between 4 and 10 ng/mL were prospectivel

17. Development and valuation of the system of synchronism between surgarcane harvester and infield wagon / Desenvolvimento e avaliação de um sistema de sincronismo entre a colhedora de cana-de-açucar e o tranbordo
One of the problems found in mechanical harvesting of sugar cane is the lack of synchronism between the harvester and the infield wagon, causing crop losses as well as reducing the operational capacity. The objective of the present research was to design a system capable to synchronize the sugar cane harvester with the wagon. The communication between tracto

18. Influence of different formulations of bleaching agents on enamel and dentin physical and chemical properties / Influencia de diferentes formulações de agentes clareadores nas propriedades fisicas e quimicas do esmalte e dentina
Section A: Effects of bleaching agents on dental enamel Since the introduction of the nightguard vital bleaching technique using 10% carbamide peroxide (10% CP), reports have evaluated the effects of bleaching agents on human enamel. Evidences show that CP is able to alter the composition and morphology of enamel substrate. In order to reduce the adverse eff

19. Medidas ultra-sonograficas da secção transversal do cordão umbilical e de seus vasos, segundo idade gestacional, em gestações de baixo risco
Introdução: mais recentemente, demonstrou-se que o diâmetro do cordão umbilical pode se modificar nos casos de diabetes mellitus, pré-eclâmpsia, restrição de crescimento intra-uterino e baixo peso ao nascimento, podendo talvez ser utilizado como um marcador para detecção precoce destas condições. Objetivo: obter intervalos de referência das medi

20. "Estudo da influência de instrumentos e técnicas alternativas de preparo cavitário na resistência de união de sistema adesivos à dentina" / Study of the influence of alternative tools and techniques of cavity preparation on teh bond strength of adhesive system to dentin
The current trend toward minimal invasive dentistry has introduced alternative cavity preparation techniques. However, these technologies should not only fulfill the requirements of a conservative philosophy, but also prepare the cavity walls for the subsequent bonding restoration. The purpose of this study was to assess the null hypotheses that: (1) both co

21. Amplificadores Ãpticos, estudos de polarizaÃÃo e geraÃÃo de pulso usando processos paramÃtricos em fibras Ãpticas
The recent telecommunication development can be, to a large extent, attributed to the capacity of transmitting information (video, sound and data) at high transmission rates (Tbits/s) through the optical fiber. The constant advances in the technological development of active and passive devices based on optical fibers have enabled a steady increase in commun

23. Energia cinÃtica de gotas de chuva simulada e energia ultra-sÃnica na desagregaÃÃo de um Cambissolo / Simulated raindrop and ultrasonic energy on the aggregate disruption and splash erosion of a Cambisol
Water erosion of soil is the main cause of land degradation over the world. Aggregate disruption of soils due to impact of the raindrops, followed by the splash of soil particles, is the first phase of the water erosion. This work aimed to quantify aggregate disruption of a typic dystrophic HAPLIC CAMBISOL (CXbd) by the kinetic energy of simulated raindrops

24. Avaliação de parâmetros ultra-sônicos utilizados na caracterização de tecidos ósseos / Assessment of Ultrasonics Parameters Utility in Customization of Bone Tissues.
A transmissão do ultra-som no organismo humano tem sido objeto de estudos a várias décadas, com a finalidade de promover diagnóstico. Recentemente tem sido usada para avaliar a densidade óssea e poder diagnosticar precocemente o aparecimento da osteoporose e prever o risco de fratura. Nesse trabalho foi desenvolvido um sistema capaz de gerar, receber e
