Perfil Socioeconômico dos Camelôs do shopping Popular

The phenomenon of the informality has been common in the quarrels that involve Sciences Social and Human. First for not corresponding to a temporary and isolated phenomenon, and on the other hand for dealing with a presente situation in the majority of the Brazilian urban centers. In Cuiabá municipality, the alternative commerce appears as a social answer to the problems caused for the economic crisis of the country and seems to be deep-rooted to the urban landscape. This assignment angles was the street peddlers, in special that ones who develop their in a specific location on lowered of Cuiabá. Researches pretending to fill a blank of information about this subject involve theoritical and empirical levels. The theory searched to raise in a generalized manner given pertinent the informality and the pratical level through field research searched to analyze excellent aspects on the economic and occupational situation of a composed sample for two hundred and theree workers who develope the pratical one of the informal commerce in Shopping Popular in Cuiaba/MT. The analysis of gotten data alllowed to appreciate some excellent aspects with regard to the activity os the peddler, as: origni, formation, income, perspectives with regard to activity among others. In las analysis it still alllowed to verify the factors that condition the permanence these workers in this type of informal activity

Desenvolvimento de circuitos planares sobre substratos têxteis

The use of flexible materials for the development of planar circuits is one of the most desired and studied characteristics, lately, by researchers. This happens because the flexibility of the substrate can provide previously impracticable applications, due to the rigidity of the substrates normally used that makes it difficult to fit into the circuits in irregular surfaces. The constant interest in recent years for more lighter devices, increasingly more compacts, flexible and with low cost, led to a new line of research of great interest from both academic and technological views, that is the study and development of textile substrates that can be applied in the development of planar circuits, for applications in the areas of security, biomedical and telecommunications. This paper proposes the development of planar circuits, such as antennas , frequency selective surfaces (FSS) and planar filters, using textile (cotton ticking, jeans and brim santista) as the dielectric substrate and the Pure Copper Polyester Taffeta Fabric, a textile of pure copper, highly conductive, lightweight and flexible, commercially sold as a conductive material. The electrical characteristics of textiles (electric permittivity and loss tangent) were characterized using the transmission line method (rectangular waveguide) and compared with those found in the literature. The structures were analyzed using commercial software Ansoft Designer and Ansoft HFSS, both from the company Ansys and for comparison we used the Iterative Method of Waves (WCIP). For the purpose of validation were built and measured several prototypes of antennas, planar filters and FSS, being possible to confirm an excellent agreement between simulated and measured results
