Comparative study of patients knowledge on osteoarthritis treatment options to ACR guidelines

Portuguese population is growing older, according to national data in 2011 the aging index was 129. The number of elderly population is higher than the younger; average life expectancy is 79,2 years (1). Because knee Osteoarthritis increases with age, and according to WHO 80% of these subjects will have some degree of impairment and 25% will not be able to do their daily living activities (2), OA has a big impact on the sustainability of both health and social care as populations grow older. Our goal was to compare current guidelines of managing knee OA, to the degree of information each patient has about their treatment options.info:eu-repo/semantics/publishedVersio

Infinite impulse response modal filtering in visible adaptive optics

Diffraction limited resolution adaptive optics (AO) correction in visible wavelengths requires a high performance control. In this paper we investigate infinite impulse response filters that optimize the wavefront correction: we tested these algorithms through full numerical simulations of a single-conjugate AO system comprising an adaptive secondary mirror with 1127 actuators and a pyramid wavefront sensor (WFS). The actual practicability of the algorithms depends on both robustness and knowledge of the real system: errors in the system model may even worsen the performance. In particular we checked the robustness of the algorithms in different conditions, proving that the proposed method can reject both disturbance and calibration errors

Evaluation of the geotechnical behaviour of a volcanic soil wall with additions of lime and cement against landslides

The construction of earth walls can be a significant response to prevent the next landslides from reaching the road and avoid accidents. Therefore, a material of the same slope was used and reinforced with mixtures of lime and cement, with this same reinforced material a mechanically stabilized hypothetical earth wall (MSE) was developed. An analysis of the original slope was developed to check if there was a possible failure through its safety factor. Then, a hypothetical wall was developed with a floor reinforced with mixtures, in order to assess its overall safety factor and its maximum landslides. According to the results, in principle it was determined that the dosage M-3 / C-4-4 improves in a range of 30% to 37% the friction angle. In addition, it was found that a reinforced wall, that is to say with Lime and cement additions, presents a better behaviour. In its effect, its displacements are about 8 mm and have a global factor of 1.23

Resposta de cultivares de milho-pipoca a doses de adubação de semeadura.

Este trabalho teve o objetivo de verificar a resposta de cultivares de milho-pipoca, quanto à produtividade e a qualidade da pipoca, a duas doses de adubação na semeadura, em três locais do Estado de Minas Gerais. Foram avaliados oito cultivares de milho-pipoca, em dois experimentos, em Lavras, Ijaci e Sete Lagoas, nos anos agrícolas de 2000/01 e 2001/02. Em um dos experimentos de cada local foram utilizados, na adubação de semeadura, 250 kg.ha-1 da formulação 8 (N): 28 (P2O5): 16 (K2O) e, no Outro experimento, 500 kg.ha -1 da mesma formulação. A adubação de cobertura foi semelhante em ambos os experimentos. O delineamento experimental foi o de blocos casualizados com quatro repetições. Foram avaliados o peso de grão (kg.ha'-1) e a capacidade de expansão (ml/g). Os resultados permitiram concluir que existe resposta para a maior dose de adubação de semeadura apenas em relação à produtividade de grãos que, em média, é de 10%, quando comparada à menor dose; o aumento da dose de adubação de semeadura não altera a capacidade de expansão e, conseqüentemente, a qualidade da pipoca, independentemente do cultivar, local e ano agrícola; o desempenho dos cultivares, quanto à produção de grãos e capacidade de expansão, varia com o ano e o local; os cultivares IAC-112, Ames-4198 e Zélia associam boas produtividades e capacidade dos expansão de grãos
