Introduction: Spinal cord injury occurs due to interuption in nerve stimuli and could caused from traumatic and non-traumatic illnes. After spinal cord, there are problems in personal life activities affecting ou modifying personal life and provoking impacts in his own life. International Classification of Functioning, Disability and Healthy (ICF) consider and analyse more than the illness ou injury and include informations about functionality in differents domains as activities, participation and enviroment. Objective: The aim of this study is to evaluate functionality wheelchair athlets with spinal cord injury using ICF. Metodology: For this research, it was evaluated 60 athlets with spinal cord injury who were practicing wheelchair basqketball, using the Checklist corresponding to the main ICF categories and othes Identity Protocol with personal datas, lesion time, lesion level and functional classification from bwheelchair basketball. Results: In analyses, we identify in quartis data, that in Body Fucntion, median was 56,67% from all athlets with light and moderate qualifications; In Body Strutucture, the median was 60% for light qualifications; in Activities and Participation, this median corresponded to 91% and in Enviroment Factors, 51,67% feel that this enviroment was facilitator...

In our country, the majority of freight and people by road happens municipal, state and federal. Thus, the heavy vehicles like buses and trucks are the main means of transporting people and cargo. This graduate work aims to study the process of manufacturing wheels for trucks, because we can see the lack of literature on the manufacturing process of wheels and also the importance of the processes used to manufacture wheels, such as lamination, stamping, puckering, machining, welding and painting

Since the beginning of the railway industry until today, rail wheels are important components to the good working of a railway. For being a critical security item, design and maintenance are done with extremely care to avoid failures. Despite de fact of railway components be projected to support a big number of cyclic solicitation during its life, some accidents still occur. These accidents, despite the low frequency, always have great consequences, drawing in great financial, material, and people losses. Nowadays, railway component failure is relatively low, because it’s been projected to work below the materials Fatigue Resistance Limit, however, with the growing demand of faster trains and higher load for each axle, the occurrence probability is even bigger. This work includes a comparative study of two fabrication processes (casting and forging) applied in the production of rail wheels where it was measured the mechanical properties of traction and fatigue. The study also verified through microstructural analysis, hardness, traction and fatigue tests, statistical analysis of fatigue test results and fractographic analysis that forging process lead to better correlations between fatigue life and mechanical properties, providing more security in railroads, less wagon retention caused by corrective maintenance and smaller operational cost with its use

This work presents a proposal to replace thetraditional system of traction electric car that usesone electric motor and a mechanical differential, by two electric motors of lower power, controlled byelectronic control low cost. The proposed control isopen loop and uses the technique of Pulse WidthModulation (PWM), discrete and synchronizedaiming to reduce the generation of harmonics. The implementation of two smaller motor one on each wheel-drive distributes the weight of the vehicle, improving the heat exchange of the windings,beyond enable the power components supporting a current of 50% predicted for only one motor . The solution adopted for being open-loop, has a similar behavior to the mechanical differential, where theeffort imposed by the trajectory makes the velocity distribution between the wheels be appropriate tovehicle trajectory

The increasing search for better performance at the automotive industry, especially on the matter of fuel consumption, caused a progressive evolution of industrial technology. For the wheel this study is based on the try of reducing mass and decreasing the moment of inertia, characteristics that directly reflect on the performance parameter, as consumption and acceleration, so that it also is effective on the growth of the profit margin, since it reduces the costs of the locomotion. In this paper will be applied the Finite Element Analysis to explain the wheel behavior and identify ways to improve the performance. To the analyze it will be simulated a test condition established by ABNT NBR 6751:2009 foreseeing a possible collapse through general yielding and fatigue. The load here presented results from the equation presented on the norms and in the datas provided by the manufacturer

Due to the increasing demand from clients and the search for better performances in the heavy vehicles industry, a progressive evolution in technology in a general way was needed. This paper uses a scientific method to validate, prior to its manufacture, the project of an agricultural wheel for sugar cane harvesters. Monte Carlo Simulation is used in conjunction with Finite Elements Method, in order to simulate the wheel's behavior in a cornering test, identify possible failure regions and get an estimate for its life under fatigue. To this end, test conditions according to EUWA Standards were simulated and obeyed, relevant to fatigue. Simulation results were interesting, according to industry experts involved in the project and manufacture of the product in question, and have provided important elements for the decision making regarding improvements that could be made on the product project before its execution

El objetivo del presente trabajo es analizar el motivo del viaje en el Libro de Apolonio, la Vida de Santa María Egipciaca y el Libre dels tres reys d'Orient , a través de los mensajes angélicos que lo guían, mensajes que funcionan como la mediación divina que posibilita la irrupción de lo sagrado en el ámbito profano, y que dota de una configuración particular asociada con la santidad a los personajes que reciben esos mensajes. Como recurso narrativo, los mensajes angélicos adquieren en estos poemas la forma de un marco posible para experiencias increíbles, que permite anticipar ciertos sucesos o encadenarlos para encauzar de manera verosímil cuestiones tan trascendentes como la conversión y la realidad medieval de los milagros.

En esta propuesta se presenta la metodología implementada y los resultados obtenidos del trabajo con nuestros alumnos de Geometría correspondiente al segundo año de la carrera de Profesorado de Matemática de la U.N.L.P sobre el problema de Apolonio, uno de los problemas más famosos de la geometría euclidiana, que a su vez da lugar a diez problemas sobre tangencias. Las construcciones que los alumnos desarrollan a partir de sus enunciados favorecen la formación de profesores de matemática por el grado de desafío interpretativo, gráfico e instrumental que plantean; por abrir espacios de discusión que promueven el enriquecimiento conceptual de los protagonistas y por dar la posibilidad de argumentar y fundamentar la postura que cada uno toma frente a cada cuestión analizada. La geometría sintética, marco del problema al que se hace referencia, resulta una teoría no elemental que, además del valor intrínseco que posee por su desarrollo histórico y la importancia que en ella tienen las demostraciones fuertemente apoyadas en los esquemas, aporta una mirada particular sobre las diferentes geometrías junto con modelos que permiten avanzar, por ejemplo, sobre las geometrías no euclidianas. El enfoque de actuación es geométrico (y no algebraico) ya que se trata de que los alumnos adquieran este tipo de pensamiento como una herramienta para su propio desarrollo y su futuro profesional

El artículo lleva a cabo una revisión de las formas de la generosidad presentes en los tres poemas que componen el Ms. K-III-4 de la Biblioteca de San Lorenzo de El Escorial (Libro de Apolonio, Vida de Santa María Egipciaca, Libre dels tres reys d'Orient), para dar cuenta -a través de las referencias compartidas, los motivos comunes y las configuraciones similares- de la organización unitaria del códice y de su singularidad
