13. Efect of non-affected lower limb constraint and seat height on the motor performance of hemiparetics post stroke during sit-to-stand / Efeito da restrição do membro inferior não-afetado e a altura do assento sobre o desempenho motor de hemiparéticos durante o movimento de sentado para de pé
Hemiparesis following stroke reduces the ability to use the involved lower extremity during the sit-to-stand (STS) transfer, thus affecting the performance. This study investigated in hemiparetic subjects the combined effects of the non-affected lower limb (NA) constraints by supporting it on a step and the seat height for the weight-bearing on the affected

14. Peltier efect in quasiperiodic structures semiconductors / Efeito Peltier em estruturas semicondutoras quasiperiódicas
There is nowadays a growing demand for located cooling and stabilization in optical and electronic devices, haul of portable systems of cooling that they allow a larger independence in several activities. The modules of thermoelectrical cooling are bombs of heat that use efect Peltier, that consists of the production of a temperature gradient when an electri

15. Equations LORENZ IN CROSS-FERROHIDRODINÂMICA / EQUAÇÕES DE LORENZ-CROSS NA FERROHIDRODINÂMICA
In this work we investigated the problem of Rayleigh-Bénard for a magnetic binary fluid, i.e., a magnetic fluid, which consist of magnetic nanopartilces stably dispersed in a liquid carrier. The theoretical calculations were performed based on a Lorenz-like model, which transforms a system of partial differential equations into ordinary differential ones. T

17. CONCRETE MICROESTRUTURE STUDY WITH ADDITION OF UNGROUND RESIDUAL RICE HUSK ASH WITHOUT BURN CONTROL / ESTUDO DA MICROESTRUTURA DO CONCRETO COM ADIÇÃO DE CINZA DE CASCA DE ARROZ RESIDUAL SEM BENEFICIAMENTO
The use of mineral adition in concrete is a widely studied theme for several researchers that looking for features like: save cement for reducing costs, durability improvement to increase mechanical strenght and use of industrial wastes for reducing environmental pollution. This study intend to analize the microstructure of concretes mixtures with ungrounded

18. Avaliação da regeneração óssea, sob a influência do laser de baixa intensidade, na região da sutura palatina de ratos após expansão da maxila / Evaluation of osseous regeneration, using the low-power laserterapy in the midpalatal suture in rats after maxillary expansion
Rapid maxillary expansion is one of the therapy used in the practice orthodontic to the posterior crossbite correction. Relapsed after expansion treatment required a contention device to guarantee a success therapy. The neoformation suture and the maxilla have maintained in the new position for a period to get the stability. To accelerate the osseous regener

19. A study of ordinary kriging smoothing effect using diferent statistics distributions / Estudo do efeito de suavização da krigagem ordinária em diferentes distribuições estatísticas
This dissertation presents the results of an investigation into the effectiveness of the post-processing algorithm for correcting the smoothing effect of ordinary kriging estimates. Three different statistical distributions have been considered in this study: gaussian, lognormal and inverted lognormal. As we know among these distributions, the lognormal dist

20. Estudo de poços parabólicos largos de AIGaAs em campos magnéticos altos / Study of wide parabolic quantum wells of AlGaAs in high magnetic fiels
We present the results of experiments and calculations done on AlGaAs Parabolic Quantum Wells (PQWs) grown on GaAs by molecular beam epitaxial tecniques. Transport measurements in n-type and p-type samples with widths between 1000 ºA and 4000 ºA at low temperatures indicate an abrupt increase of the Hall coeficient at a critical field B ¼ 3 T. Our study f

21. Physiotherapy and society: action of Sistema Único de Saúde no Rio Grande do Norte / Fisioterapia e sociedade: ações do Sistema Único de Saúde no Rio Grande do Norte
The work has objective to present actions of Physiotherapy, developed by SUS in the State of Rio Grande do Norte; discuss under the humanization point of view such actions of health; discuss the importance of physioterapy to the Norte-Riograndense, or maybe its role in the perpetuation of actions of health centered in the binomial cause/efect. The study was

22. Regression model for a Weibull renewall process distribution with a frailty efect / Modelo de regressão para um processo de renovação Weibull com termo de fragilidade
Processsos de renovação são um caso especial de processos pontuais envolvendo eventos recorrentes nos quais um item ou unidade, após a ocorrência de uma falha, é recolocado na mesma condição de novo. Devido a essa propriedade os tempos entre ocorrências para um processo de renovação são independentes e a sua função intensidade é dada pela fun�

23. Acquisition and processing of morphometric parameters derivatives from SRTM model / Aquisição e processamento de dados morfométricos derivados do modelo digital de elevação SRTM
SRTM data is distributed at horizontal resolution of 1arcsec (aprox. 30m) for areas within the USA and at 3arcsec (aprox. 90m) resolution for the rest of the world. A 90m resolution can be considered suitable for small or medium-scale analysis, but it is too coarse for more detailed purposes. One alternative is to interpolate the SRTM data at a finer resolut

24. Efeito do entorno urbano sobre as ações do vento em edifícios / Influence of the urban environment on wind loads on buildings
Neste trabalho de pesquisa desenvolveu-se uma metodologia, através de ensaios em túnel de vento, para determinar as cargas sobre estruturas altas situadas em centros urbanos e considerando a distribuição aleatória do entorno superficial. Assim, como este estudo trata do problema da determinação de cargas de estruturas situadas em centros urbanos, prod
