This work aims to present the design and development of a speed reducer worm gear that will be implemented on an inclined treadmill that aims to raise the load below the top floor. The project start was made with research on issues related to mechanisms and machine elements, and these theories of fundamental importance in the development of device components, along with the help of SolidWorks software that was used to model the main parts of the project and Microsoft Office Excel 2007 was used to alight formulas to perform calculations of the project. All data for calculations were taken from the conditions of the problem to be solved in the best possible way the proposed problem (lifting load from the belt). Following the entire sequence of design gearbox assembly, beginning in pre-sizing and endless selection of electric motor, which consists of an iterative project, then scaling the worm gear and crown, shafts, splines, calculation and bearing selection

This paper analyzes the dynamics of Brazilian cultural policy between 1995 and 2010. Studies related defend the existence of a "contrast" between the results obtained by the government of Fernando Henrique Cardoso (1995-2002) and Luiz Inácio Lula da Silva (2003- 2010), that divide it between a model "neo-liberal" and a "democratic" model of cultural policy. Our main achievement is to produce empirical knowledge that can verify these claims. The build of indicators was guided by the theoretical assumption of the historical new institutionalism, discussed by Pierson (2006), and the observed universe comprises the totality of cultural producers who have submitted projects to “Mecenato”, registered in SALICNET - Ministry of Culture.

The objective of the present work was to study the control of the dynamics of diatomic heteronuclear molecules interacting with electric fields created by lasers. Specifically in this work, the molecular photoassociation phenomenon will be analyzed. At this phenomenon, the atom's relative movement is described by a particle that moves in a morse potential well under the influence of an external time dependant force related to the external field. Based on the optimum control theory (OCT), it is presented at the present work laser pulses that alternate a given initial molecular state to a desirable end state, wich in this work was represented by the minimization of a cost functional that indicates how close. To do so, a computational sistem know as Genetic Algorithm (GA) was developed that can be characterizes as an extremelly eficient technique capable of scanning the solutions space and find results close to the optimum solutions
