Objective: to create a purchasing system for optimizing a low cost device fabrication itself. Method: For this purpose was designed a system which is powered by a 12V battery center. The full bridge of "Wheatstone" is powered by the central battery set to 9V. Results: The sign of the strain has a range of 0 to 30 mV which is amplified filtered by a signal conditioner own manufacturing using an LM 324. The electrical signal then passes to vary from 0 to5V which will be processed in an analog input of PIC microcontroller. Tests for the registration and interpretation of data are through software MyOpenLab. Conclusion: The work is in progress and initial results suggest that the system will be able to measure muscular strength accurately and cost-effective.

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.

The traditional model of teaching little is modernized in recent decades. When in contact with this system, it is normal that the new-generation students feel unmo tivated in carrying out the proposed activities in the classroom. Considers Prensky (2001) these students, called Digital Natives, born with a modern way of thinking and learn and feel encouraged and motivated with activities that invite to interact. For this reason, it has been proposed the development of an object of learning in the form of application for Android tablets, exploring the internal sensors available in them, with the purpose of offering an interactive activity to students on the physical concepts involved in the process of photosynthesis in plants. For the construction, informational texts written in didactic language and easy to understand, illustrative images and animations were employed. In addition, we used the light sensor in the interactive activity on the process of photosynthesis so that the student could observe and understand how the environment is able to interfere with this process

The implantation of environmental management systens (SGA) in companies is the first step to the company conquers the environmental certification and consequently the benefits of a sustainable production of products, services and activities can bring. However, in the way as they are proposals in bibliographies the implantation of the SGAs, does not identify the definition of the operational stages of implementation of the same ones, generating doubts on the real environmental and administrative performance that they can come to generate for the organization. In this direction, the present research brings a proposal of operational systematics for implantation of SGA in companies, detailing each stage of implantation, considering its particularitities. For in such a way, a revision of norm NBR ISO 14001:2004 was made, looking for to identify to the interpretation imperfections gifts in the normative system. Moreover, other methods of SGA implantation had been searched gifts in the bibliography, searching proposals that detailed the operational aspects of the implantation of the system. In the same way, the accomplishment of a period of training supervised in the first semester of 2007 made possible the practical experience of the functioning of a system of environmental management, beyond the contact with professionals of the area and the acquisition of documents that had helped in the development of the research. The result was the attainment of a detailed procedure more, defining the operational systematic of SGA implantation, beyond the generation of a flowchart, describing as to develop each stage. This detailing certainly will facilitate the implantation of a SGA in companies interested in improving its environmental performance.

In the current decade, inter modal transport is widely discussed. In Brazil road transport is used in excess whereas there could be more focus and investment towards water transport. Water transport presents many benefits like being low cost and low maintenance. Sea and river ports today aren't capable of supporting Brazil's transport needs. Therefore, with this obstacle, this paper consists of an attempt of modeling and simulation of the process of unloading grain cargo from trucks, through simulation with ProModel software, to verify the necessity of installing more tumblers at the cargo unloading station in Porto Murtinho, MS
