Patente de invenção pertencente ao campo dos equipamentos eletrônicos de medição de dados pluviométricos que consiste no desenvolvimento de um sistema automático para aquisição de dados pluviométricos (índice de chuvas), que é composto de um coletor eletrônico de dados (hardware e software embutido) e em um software de manipulação de dados em ambiente PC. O coletor pode ser utilizado como uma ferramenta em diversos campos, como meteorologia, agronomia, biologia, construção civil, ciências ambientais, defesa civil, educação etc. O coletor deve ser conectado a qualquer pluviômetro do tipo basculante, que funciona como uma espécie de sensor, e então passa a registrar automaticamente quantidade de chuva ocorrida em um determinado local, durante um determinado período de tempo.

The paper discusses the application of High Strength Concrete (HSC) technology for concrete production with the incorporation of Rice Husk Ash (RHA) residues by replacing a bulk of the material caking and rubber tires with partial aggregate volume, assessing their influence on the mechanical properties and durability. For concrete with RHA and rubber, it was possible to reduce the brittleness by increasing the energy absorbing capacity. With respect to abrasion, the RHA and rubber concretes showed lower mass loss than the concrete without residues, indicating that this material is attractive to be used in paving. It is thus hoped that these residues may represent a technological and ecological alternative for the production of concrete in construction works.

AIM: In this paper we estimate the sediment yield and other related information for a small urbanized watershed, located in Sorocaba, São Paulo State. The driving forces that produce the observed scenario are presented and discussed; METHODS: Over a year, water samples and hydrologic information concerning the river channel were collected monthly at one sampling site. In the laboratory, water samples were oven dried (80 ºC) and the total suspended solid weighed for each sample. To estimate sediment yield we used Colby's simplified method. The sediment delivery ratio (SDR) was estimated using two methods: the relief - length ratio and the bifurcation ratio; RESULTS: The annual sediment yield estimated for the period was 1,636.1 t. The total specific sediment yield was 541.7 t.km -2.y-1. Bedload was the predominant fraction. The SDR changed between 60 and 66% according to the method employed. CONCLUSIONS: The main driving forces of hydrosedimentological disequilibrium are the lack of riparian vegetation, the dumping of construction wastes at inadequate sites, and the launching of untreated sewage. Hence, if these three factors were controlled, a significant improvement in the environmental quality, particularly water quality, might be achieved.

The Brazilian construction is with high production which resulted in many service industries and also for businesses that work in conjunction with it. For the furniture industries would not be different, since they are intimately involved with the construction. To meet the demand for furnishings in Brazil, some clusters of industries have developed in recent years, as in the case of Uba (MG), Arapongas (PR) and Bento Gonçalves (RS). For industries sector can always increase its production combining quality and customer satisfaction, is necessary for their production procedures are studied and improved every day. The aim of this research is to propose a solution for simple information system involving the issue of tracking parts of the furniture produced in an industry custom furniture that depend on outsourced services. The research occurred during four months of the year 2013 for the observation of the production of the industry, where possible observing interference could be carried out with the aim of obtaining improvements in the production line. It is concluded that control of the finished product in a custom furniture industry is a very complex work, because the information system must transmit information faithful, which has not happened formerly, but after the implementation of the identification system was significant improvement the transfer of information between sectors mounts internal and external furniture
