El objetivo del presente trabajo es recopilar y sistematizar el conocimiento agropecuario popular nicaragüense por la Universidad Nacional Agraria (UNA) de Nicaragua, ha realizado trabajos de tesis a lo largo de toda su historia (98 años), para validar estos conocimientos que son de utilidad para nuestros productores, mediante la utilización del método científico. Para este estudio se realizó un análisis de documentos los cuales, son considerados una fuente valiosa de información. El trabajo de campo se realizó en los meses de noviembre 2013 a noviembre 2014, la información fue obtenida en el Centro Nicaragüense de Documentación Agropecuaria (CENIDA) de la UNA, ubicada en Managua en el km 12 ½ carretera Norte, y demás instituciones que han trabajado junto con la UNA en la elaboración de estos trabajos científicos, se tomaron variables de importancia en la vida diaria del productor, como son los granos almacenados, carbón vegetal, recursos forestales, producción de leche, sanidad animal, y las aves de patio, todas estas influyentes en la economía y alimentación de las familias campesinas. Se encontró que la UNA ha realizado un total de 2 737 tesis, de las cuales solo se encontraron 21 tesis basadas en el conocimiento indígena, campesino y popular, teniendo más temas de investigación en las áreas de sanidad animal 7 tesis, granos almacenados 5 tesis, recursos forestales 4 tesis y las de menor temas de investigación producción de carbón vegetal 2 tesis, producción de leche 2 tesis, producción de aves de patio 1 tema de tesis

Resgata pequena parte da história do anarquismo, que praticamente desapareceu do cenário político brasileiro. Utilizando o método de análise historiográfica, e compulsando os registros de sessões ocorridas, analisa a participação da Câmara dos Deputados nas políticas relacionadas à repressão dos anarquistas nas greves ocorridas em 1917. Ao final da pesquisa, chega-se à conclusão da existência de razoáveis indícios de participação da Câmara dos Deputados nas ações de repressão ao movimento anarquista.

Apresenta um estudo sobre a experiência anarquista no Brasil. Investiga a repercussão na Câmara dos Deputados das greves operárias realizadas em 1917 a partir de registros de atividades do Plenário. Analisa o papel desempenhado pela Câmara dos Deputados na política de expulsão de estrangeiros adotada pelo governo brasileiro durante a segunda década do século XX.

In this paper, the influence on corrugation of the most significant track parameters has been examined. After this parametric study, the optimization of the track parameters to minimize the undulatory wear growth has been achieved. Finally, the influence of the dispersion of the track and contact parameters on corrugation growth has been studied. A method has been developed to obtain an optimal solution of the track parameters which minimizes corrugation growth, thus ensuring that this solution remains optimum despite dispersion of track parameters and wheel-rail contact uncertainties. This work is based on the computer application RACING (RAil Corrugation INitiation and Growth) which has been developed by the authors to predict rail corrugation features.

Based on the computer integrated and flexible laser processing system, an intelligent measuring sub-system was developed. A novel model has been built up to compensate the deviations of the main frame-structure, and a new 3-D laser tracker system is applied to adjust the accuracy of the system. To analyze the characteristic of all kind surfaces of automobile outer penal moulds and dies, classification of types of the surface、brim and ridge(or vale) area to be measured and processed has been established, resulting in one of the main processing functions of the laser processing system. According to different type of surfaces, a 2-D adaptive measuring method based on B?zier curve was developed; furthermore a 3-D adaptive measuring method based on Spline curve was also developed. According to the laser materials processing characteristics and data characteristics, necessary methods have been developed to generate processing tracks, they are explained in details. Measuring experiments and laser processing experiments were carried out to testify the above mentioned methods, which have been applied in the computer integrated and flexible laser processing system developed by the Institute of Mechanics, CAS.

This paper sets out an optimum synthesis methodology for wheel profiles of railway vehicles in order to secure good dynamic behaviour with different track configurations. Specifically, the optimisation process has been applied to the case of rail wheelsets mounted on double gauge bogies, that move over two different gauges, which also have different types of rail: the Iberian gauge (1668 mm) and the UIC gauge (1435 mm). Optimisation is performed using Genetic Algorithms and traditional optimisation methods in a complementary way. The objective function used is based on an ideal equivalent conicity curve which ensures good stability on straight sections and also proper negotiation of curves. To this end the curve is constructed in such a way that it is constant with a low value for small lateral wheelset displacements (with regard to stability), and increases as the displacements increase (to facilitate negotiation of curved sections). Using this kind of ideal conicity curve also enables a wheel profile to be secured where the contact points have a larger distribution over the active contact areas, making wear more homogeneous and reducing stresses. The result is a wheel profile with a conicity that is closer to the target conicity for both gauges studied, producing better curve negotiation while maintaining good stability on straight sections of track. The paper shows the resultant wheel profile, the contact curves it produces, and a number of dynamic analyses demonstrating better dynamic behaviour of the synthesised wheel on curved sections with respect to the original wheel.

The objective of this paper is to compare 3 types of track (high performance ballasted track, STEDEF and AFTRAV) from the corrugation growth point of view. This work has considered different vehicle speeds and track radii, and the results have taken into account the four wheels of a bogie. These tracks have been studied using Finite Elements with Nastran-Patran and RACING, a tool developed in Matlab by the authors which estimates the corrugation growth tendency. The tracks are studied using the Finite Strip Method and the Periodic Structure Theory. Lateral and vertical receptances for track and vehicle have been obtained, as well as the corrugation growth functions. In the paper the tracks are ranked according to corrugation development.
