We know that the orbit of a lunar satellite, and consequently its orbital lifetime is mainly inuenced by the gravitational field of the Moon, Earth and Sun. In this text we study the Lunar gravitational potential and its influence on the gravitational field. We adapted a program in order to map the Moon gravitational field. To that end it was necessary to develop a program that allows the simulation and mapping the lunar full potential. Our program was based on the program developed by Hélio Kuga, and adapted to our case (Moon). We used the model proposed by Konopliv et al. 2001, we proposed various degree and order expansions of spherical harmonics that served us to compare and validate our program

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

The housing issue in Brazil is'nt a recent problem and has been discussed, worked and questioned in the institutional framework, especially with regard to the critical considerations on the topic and urban problems involved. We as milestones in the Brazilian housing policy the National Housing Bank - BNH, 1964, the height of the military regime in Brazil, and the Minha Casa, Minha Vida, in 2009. Both have questions that approach and distance themselves regarding changes in the Brazilian housing policy, where we have the emergence of new forms of knowledge production and housing consumption. Thus we have a number of advances in ways of acquiring social housing, even at different times, it is characterized as capitalist forms of this issue. Thus the spatial process of housing developments arising from these programs reflect the change in space - time that they lay down, turning the urban space of the cities in this case the city of Presidente Prudente / SP
