13. Morfotipagem, caracterizaÃÃo fisiolÃgica de leveduras isoladas de secreÃÃo vaginal e sensibilidade a prÃpolis e lectinas
The yeasts, especially the candidoses, are assuming a role of great importance in the human pathology. The female genital tract may be affected by infectious and inflammatory processes, which are diagnosed by examination of vaginal secretion. Several species of yeasts have been isolated from the vulva and vagina in normal cases and vulvovaginitis. Aiming to

14. Caracterização termomecânica de compósitos híbridos com memória de forma
The Shape Memory Alloys - SMA - are materials with the ability to recover a certain geometric form previously established upon heating. This singular behavior enables their application in many situations, from orthodontic arches and medical instruments to adaptative structures for shape and vibration control. Due to the complexity of their thermomechanical b

15. Construção de nanoestruturas e caracterização por SEM e RBS / Construction of nanostructures and characterization by SEM and RBS
Nanostructured materials have properties that make these materials different from their counterpart in higher scale that opens many novel possibilities and technical applications. One of the main issues in nanotechnology is to develop suitable methods for the analysis and characterization of nanostructures. This works studies the use of Rutherford Backscatte

16. Estudo integrado de análogo a reservatórios petrolíferos fluviais: caracterização, parametrização e modelagem tridimensional de depósitos recentes do Rio Assu (Rio Grande do Norte/Brasil)
This work shows a integrated study of modern analog to fluvial reservoirs of Açu Formation (Unit 3). The modern analog studied has been Assu River located in the same named city, Rio Grande do Norte State, Northeast of Brazil. It has been developed a new methodology to parameterizating the fluvial geological bodies by GPR profile (by central frequency anten

17. LINEAR ULTRASONIC MOTOR WITH TUBULAR GEOMETRY / MOTOR ULTRA-SÔNICO LINEAR COM GEOMETRIA TUBULAR
This work presents the study on a linear ultrasonic motor with tubular geometry for linear displacements. Similar topologies, reported elsewhere, are conceived for producing rotary motions. Due to some particular characteristics of this geometry, not explored yet, a new study on interaction between resonance modes in a hollow cylinder for linear movement gen

19. Theoretical-experimental study of the drain current transient and generation lifetime in SOI MOSFETs technologies. / Estudo teórico-experimental do transitório da corrente de dreno e do tempo de vida de geração em tecnologias SOI MOSFETs.
This work presents a study of drain current switch-off transients and extraction methods of the generation lifetime in partially depleted SOI nMOSFET transistors of single gate, double gate and triple gate FinFETs. This study is accomplished through two-dimensional numerical simulations and compared with experimental data of devices fabricated in the IMEC (I

20. Integrated crop-livestock and soil physical quality in Brazilian Cerrado / IntegraÃÃo Lavoura-PecuÃria e a Qualidade FÃsica do Solo na RegiÃo do Cerrado
Soil physics plays a fundamental role in conserving soil and water in agricultural landscapes and is also a key parameter for accessing the sustainability of agropastoral systems. Both pasture history and management can have a significant effect on soil physical attributes, but conclusive research on this subject remains fragmentary. This work aimed to quant

21. WX2X2: A SOFTWARE FOR NONLINEAR SYSTEMS / WX2X2: UM SOFTWARE PARA SISTEMAS NÃO LINEARES
We present a software to invert functions from the plane to the plane F(x) = b, for a generic smooth function F, as well as the theory to implement it. In principle, all points in the preimage of b are computed. The numerical inversion is based on the characterization of the critical set C = {x pertence R2 : detDF(x) = 0} and its image, and in appropriate te

23. Cruzetas de polímeros reciclados: caracterização dos materiais, análise numérica e ensaios de modelos reduzidos / Recycled polymer crossarms: characterization of the materials, numerical analysis and tests in reduced models
Nowadays, wood is still the most used material in crossarms of aerial power distribution lines in Brazil. However, it has caused problems to power utilities concerning (i) degradation due to defects and attacks of fungi and insects, (II) higher operational costs to replace damaged pieces and (III) environmental problems, as the raw material has become scarce
