25. Identificando padrões comportamentais do tipo avoidance em trajetórias de objetos móveis / Identifying avoidance behavior patterns in moving objects trajectories
With the increasing availability and considerable price reduction of technologies that allow the collection of moving object data, the offering of trajectory data becomes abundant. The study of these trajectories has the objective to allow a better understanding of the data, as well as the extraction of new knowledge using computational techniques. One of th

26. Measuring statistical geometric properties of tomographic images of soils
Porous media modeling is relevant in several applications, such as agricultural engineering, where soil compaction analysis requires the estimation of soil transport properties. For example, the prediction of root growing patterns and their environmental impact is usually measured by analyzing soil fluid infiltration capacity and water retention. Recently, t

27. Rules extraction from neural networks applied to the prediction and recognition of prokaryotic promoters
Promoters are DNA sequences located upstream of the gene region and play a central role in gene expression. Computational techniques show good accuracy in gene prediction but are less successful in predicting promoters, primarily because of the high number of false positives that reflect characteristics of the promoter sequences. Many machine learning method

28. O advérbio em fraseologias das áreas da culinária e do direito contratual: um estudo baseado em corpus / The adverb in phraseologies in the areas of Culinary and Contract Law: a corpus-based study
When analyzing the material available nowadays about adverbs in English and in Portuguese we observe, especially in those that are corpus-based more specifically grammar books , that the study of this grammatical class has gained ground. Besides covering topics such as morphology, syntax, pragmatics, semantics and sometimes discourse, these reference books h

29. Identificação de bovinos através de reconhecimento de padrões do espelho nasal utilizando redes neurais artificiais / Identification of bovines through recognition of images patterns of the muzzle using artificial neural nets
Artificial Neural Networks (ANN) are mathematical models associated with artificial intelligence that can learn and generalize information, therefore they can be used as images classifiers. This paper aims to analyze the cattle muzzle in order to prove that it is a unique and permanent characteristic of the animal thus, being used as its unique identificatio

30. Memória social e ecologia histórica: a agricultura de coivara das populações quilombolas do vale do Ribeira e sua relação com a formação da mata atlântica local / Social memory and historical ecology:slash and burn agriculture in the formation of an Atlantic rainforest area inhabited by quilombola communities, Ribeira Valley, Brazil
The Atlantic Rainforest is one of the worlds most diverse and threatened biomes. The majority of its remnants are located at the Ribeira Valley (SP) where several of the States quilombola populations remain. The Valleys quilombos originated from a population of freed, abandoned or refugee slaves brought to the region in the beginning of the European coloniza

31. Vancomycin use in a brazilian teaching hospital: comparison with the Hospital Infection Controlpractices Advisory Committee Guidelines (HICPAC)
This study describes vancomycin prescribing patterns in an average complexity hospital and compare the guidelines proposed by the Hospital Infection Control Practices Advisory Committee (HICPAC). The study was conducted in a 256-bed secondary-care hospital. Data were collected of all patients given vancomycin from March 2003 to February 2004, using a standar

32. Eliciting the evolution of spatiotemporal objects with case-based reasoning / Extração da evolução de objetos espaço-temporais com raciocínio baseado em casos
One of the main challenges in the information extraction provided by remote sensing images is to model and to represent geographical objects that have their properties changed along the time. This thesis proposes a novel approach based on Case Based Reasoning (CBR) for describing how geospatial objects identified in remote sensing imagery evolve. Given a set

33. DETECÇÃO DE ESPÉCIES BACTERIANAS ENVOLVIDAS EM PROCESSOS DE BIODESSULFURIZAÇÃO EM UM SISTEMA DE LANDFARMING, NA REFINARIA GABRIEL PASSOS (REGAP), MINAS GERAIS.
The emission of sulfur from the burning of fossil fuels represents a global problem because it is the major cause of acid rain and air pollution. A major concern of the refineries is reducing the sulfur content of oil. The technology commonly used for this purpose is the hydrodesulfurization. An alternative that is being increasingly considered is biodesulfu

34. Associação entre polimorfismos do gene do receptor alfa de estrogênio com a densidade mamográfica em mulheres após a menopausa. / Estrogen alpha receptor gene polymorphisms association with mammographic density in postmenopausal women.
Introduction: Genes that encode proteins involved at biosynthesis, action and metabolism of sexual steroids are polymorphics. This condition could explain individual variations in mammographic density. The objectives of this study were to evaluate a possible association of clinical characteristics and polymorphisms HaeIII, MspI and XbaI of the estrogen recep

35. Petrologia e metalogenia do depósito primário de nióbio do complexo carbonatítico-foscorítico de Catalão I, GO
The Catalão I carbonatite-phoscorite complex is part of the Alto Paranaíba Igneous Province (APIP) and consists of a multi-intrusion body zoned from bebedourite-(piroxenite)-series rocks in the border to carbonatite- and phoscorite-series rocks in the core. The phoscorite-series rocks consist of apatite, magnetite and a Mg-silicate (phlogopite or olivine)

36. Retina de aves como sistema circadiano e sua modulação por luz e glutamato / Avian retina as a circadian system and its modulation by light and glutamate
The avian circadian system is composed by the retina, the mammalian homolog region of the supra-chiasmatic nucleus (SNC) and the pineal gland. The retina itself shows many rhythmic physiological events, such as movements of photoreceptor cells, opsin expression, retinaldehyde re-isomerization, melatonin and dopamine production and release. Altogether these r
