Since 2000 the use of the GPS navigation increases considerably. The reason for that was the deactivation of the selective availability in May 2000. However, these receivers do not register the observables, they just estimate and store them and that prevents the post-processing data. Based in this aspect some softwares were developed and are available for free. They allow recording the GPS observables, pseudorange and carrier phase. These programs are able to read in binary files and record information concerning the GPS observables and to convert binary format to a RINEX format. This study presents the GPS Garmin 12 XL evaluation using free programs. Two experiments were carried out in Presidente Prudente-SP region using the relative static survey. The processing was carried out with intervals of 30, 15, 10 and 5 minutes. The results were compared with the coordinates from a geodetic receiver and show that 98.9 % of the points, the values in relation to the planimetric accuracy were better than 0.50 m. The only baseline which the value was larger or equal to 0.50 m is the point M0001 (baseline lesser than 2 km) referred to the first experiment. In terms of precision the values did not exceeded 0.30 m.

Indivíduos com Paralisia Cerebral apresentam desenvolvimento motor atípico, caracterizado por alterações posturais, de coordenação motora e de tônus muscular, que resulta em limitações no desempenho de atividades funcionais. Neste contexto destaca-se a prescrição e confecção de recursos de tecnologia assistiva com objetivo de maximizar as habilidades funcionais destas pessoas e prover sua inclusão social. Os indivíduos com paralisia cerebral, muitas vezes, têm dificuldade para a manutenção da dinâmica corporal, principalmente na postura sentada. O objetivo deste estudo foi o de confeccionar uma cadeira e mesa escolar adaptadas com material de baixo custo e verificar sua eficácia no desempenho grafomotor de uma criança com paralisia cerebral. O participante foi uma criança com diagnóstico de paralisia cerebral diplégica, do gênero masculino. A coleta e registro dos dados foram feitos em três momentos, com a criança posicionada no mobiliário adaptado, no mobiliário escolar comum e novamente no mobiliário adaptado, para se estabelecer a comparação. A análise de dados se deu por meio de testes estatísticos não paramétricos. Não houve significância estatística e foi verificada uma inconstância nos dados apresentados, já que não se pode afirmar ao certo qual mobiliário foi mais eficaz na realização da atividade proposta e nem se houve aprendizado motor com a sua repetição. Esse fato não invalida a adequação de mobiliário escolar ao aluno com paralisia cerebral, visto que este é um fator importante para favorecer o controle e estabilidade postural ao individuo, o que interfere na coordenação motora fina destes indivíduos, influenciando no seu desempenho em atividades escolares.

Many variables are indirectly involved in the transformation of raw material into a metallurgical industry, such as machine hours, hours of hand labor directly and / or indirect, setup time, etc. This research focuses on the complexity of formulating the cost of metallurgical products, based on a case study, in which one has incurred a large loss on the sale of a product called Punch. The main objective of this work is to define the variables of the cost of members and other metallurgical products, so simplified general, checking what were the failures costing the case studied, in order to help others. The method of formulating cost was determined as recommended by SEBRAE guidance for small businesses. The results showed a loss R$ 13.201,00 in the batch of 15 units of punch. Possible improvements have been identified for reducing the production cost

Are being released in the construction market in Brazil ventures called Super 6. These businesses sell the promise of delivery of the apartment in six months after the launch of the venture. To meet this deadline are being deployed the constructive method of concrete walls using aluminum shapes. This system basically consists of pouring slabs and walls once, i.e. building up the wall shapes and slab joints. On the walls are used cloth, with reinforcements in vain and corners of walls and on these screens are tied the electrical boxes and conduits. For each tower is used the so-called system of half way, i.e. the system so it is sufficient to mount the Middle deck. Using a concrete which can be deformed in the next day you can lift one deck every two days with ready electric and hydraulicsystem, without having to tow the wall doing only minor fixes in the imperfections after concrete. With this system won an incredible speed in the construction of the structure reducing in almost one-third the length of the work. This work aims to compare in terms of cost-benefit of masonry structural systems and this new concrete wall system called Super 6. For this comparison will be used as parameter values used for the achievement of the Enterprise Portal of Roses of constructor Tenda which is one of the first to use concrete wall system. This project basically consists of seven towers of six floors each and will be budgeted the cost of this project if it were held in structural masonry. From these data it will be possible to make a comparison about the actual beneficial to adopt this system

A large part of hydraulic hoses is produced on a mandrel. The mandrel has longer length and circular profile being produced by extrusion of polyamide polymer, which in this case is imported, then the process is depending on the import process, which entails high shipping costs and fees. This work studies the production of recycled mandrel, using the mandrel that is out of dimensional to produce hoses. After the production of recycled mandrel mechanical tensile and hardness were performed both in the natural and recycled mandrel to compare them. It was observed that recycled mandrel presents the tensile properties and hardness superior to natural mandrel. Thus, this work will directly impact the company`s business ultimately reducing costs, reducing waste and reducing environmental impacts

In the past years, soya has increased itself as the mean agro export culture in Brazil, encouraging the expansion of its agricultural frontier throughout the country. Brazil is the second biggest soya producer around the world, with a 59,8 million ton production in 2008, according to the Instituto Brasileiro de Geografia e Estatística (IBGE), only behind United States. Around the country, the four leading producer states are Mato Grosso, Paraná, Rio Grande do Sul e Goiás. Therefore, geotechnologies may be used to monitor use and soil occupation in various analyzes periods. In this review, the tools are important to illustrate the soya production areas and also the weather behavior around its production evolution in the territory through the years. Its utilization can contribute to the evolution and optimization around real time monitoring of the Agricola cultures, without being necessary to be in the area with a low financial cost. Generally, this information is strongly important for decision makers in both government and private sector, as soon as the achievement information regards the quantification of area, yield and development of agricultural crops are essential to the economic behavior of culture during the season and even beyond. By obtaining data regarding climate crops 2008/09 and 2009/10, held the climatic water balance calculation based on the dynamics of water storage in soil temperature and precipitation data, interpolation of the data through the interpolator (IDW) that generated thematic precipitation maps. Overall, the use of geotechnology to monitor agricultural areas, can strongly contribute to this monitoring, generating raw material for further analysis at low cost
