25. Crop discrimination using harmonic analysis of EVI MODIS time-series data / Discriminação de culturas agrícolas utilizando análise harmônica de séries temporais de dados EVI-MODIS
In the present decade, agriculture has increased worldwide in importance due to sensitive matters such as the current food crisis, biofuels boom, and the land use and land cover changes from savanna/forest areas to agriculture expansion. As a consequence, crop monitoring at regional and national scales has become essential at different levels of knowledge an

26. Modelagem espaço temporal do uso do solo e potencial de erosão no Vale do Ribeira / Spatio temporal modeling the soil use and potential of erosions in the Ribeira Valley
This paper comprises an experiment to map hidden patterns in multi-source data that could be associated with Pb geochemical soil anomalies. The study area is confined between the Apiaí Fold-Belt, hosts numerous Pb and Zn deposits; it was under the influence of regional Pb mining and Pb refinery factory activities until 1995; and exhibits soils enriched in P

27. Performance dos indivÃduos nos testes de progÃnies e os respectivos clones de eucalipto
In order to compare the performance of individuals selected in progenies test and the clones derived from them, 196 full-sib progenies were appraised, at two and four years of age, using four commercial clones as control. The experimental design was randomized complete blocks with five replications and five plants per plot, spaced 3.0 x 3.0 m. The experiment

28. Isomeric State Measurement System / Sistema para medida de estados isoméricos
A system, called SISMEI (Isomeric State Measurement System), was developed for the detection and measurement of isomeric states with half-lives in the range of 10 ns to 10 s without the use of a pulsed beam. This system mainly uses the technique of charged particles and -ray delayed coincidences. In SISMEI, the statistical background is reduced by the separa

30. Study of a 4?(PS)?-? Coincidence System for Absolute Radionuclide Activity Measurement Using Plastic Scintillators / Estudo de um sistema de coincidências 4-pi-beta-gama para a medida absoluta de atividade de radionuclídeos empregando cintiladores plásticos
The present work was intended to study a coincidence system 4?(PS)?-? for absolute activity measurement using plastic scintillators in 4? geometry. Along with experiments on the coincidence system, simulations were also performed applying the Monte Carlo Method, by means of codes PENELOPE and ESQUEMA. These simulations were performed in order to calculate th

31. Study of allelic frequency of five X-Chromosome?s loci STR on Sao Paulo State people and its role in human identification / Estudo de freqüência alélica de cinco loci STR do cromossomo X na população do Estado de São Paulo e sua contribuição na identificação humana
The forensic identification through DNA analysis is, frequently, done by the study of DNA?s polymorphic regions, such as STR, short tandem repeats. In order to use these markers in human identification, it?s necessary to know the allelic distribution in the population in wich the person belongs. This research aimed to settle the allelic frequencies of five X

32. Development of a urinary lithiasis localizer mechanism to couple ultrasound and extracorporeal lithotripsy equipment in canine model
INTRODUCTION: Due to the evolution of extracorporeal lithotripsy equipment (ESWL) and presently, the fact that most part of the equipment does not present ultrasound to localize urinary calculi, a system that allows adapting ultrasound equipment to ESWL equipment was developed, disposing only of fluoroscopy. Thus, this equipment was developed and was tested

33. Effect of two solanaceous plants on developmental and population parameters of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)
Tuta absoluta (Meyrick) is an important tomato pest that also feeds on other host-plants from the Solanceae family. We studied the effect of two cultivated plants, tomato (Lycopersicum esculentum Mill.) and potato Solanum tuberosum L. on the development and populational parameters of T. absoluta related with host-plant suitability. Larval developmental time,

34. Evaluation of the relationship amongst the working groove angulation of artificial teeth and the orientation plane and the vertical rotation axis of mandibular lateral translation in the articulator / Avaliação da angulação do sulco de trabalho de dentes artificiais em relação ao plano de orientação e ao eixo de rotação vertical de lateralidade da mandíbula no articulador
In prosthetic rehabilitation, occlusion and mandibular movements are closely linked. Harmony between these factors is essential for treatment success. One of the main concepts approached when aiming for this goal is the relationship between teeth grooves and cuspids and mandibular movements, where cuspids must not touch grooves during these movements. Theref

35. "Identificação de mecanismos em reações induzidas por núcleos fracamente ligados" / Identification of mechanisms in reactions induced by weakly bound nuclei
In the present work, the relative importance of breakup, incomplete fusion and transfer processes is investigated in the vicinity of the Coulomb barrier for the intermediate mass target 6Li + 59Co reaction involving the weakly bound 6Li. Measurements for light particle angular distributions were performed at energies Elab = 18, 22, 26 e 30 MeV,elastic scatte

36. Theoretical and experimental analysis of cold-formed steel members under compression / Análise teórica e experimental de perfis de aço formados a frio submetidos à compressão
Cold-formed steel members present, in general, higher local slenderness than classical hot- rolled ones, which make them more prone to local buckling. Besides, thin-walled open sections have small torsional stiffness, and hence global torsional and flexural-torsional instability modes are many times more critical than global flexural ones. Also, distortional
