Coletor de dados pluviométricos

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.

Hydrosedimentological disequilibrium in a small, urbanized watershed

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.

Análise das resistências de embutimento e de compressão para madeiras de pinus e eucalipto

The connections in the wood structures are the places with high concentrations of stresses and therefore are more fragile than the rest of the structure. The connections between pieces of wood can be made by metal pins (nails or screws). The compression and embedment strength has significant influence on the calculation of the connections. The main aim of this work was to evaluate the compression and embedment strength in the directions parallel, inclined at 45° and normal to the grain, using standard specimens according to ABNT NBR 7190/1997 standard. The compression and embedment strength were initially evaluated according to ABNT NBR 7190/1997, which admits the deformation of 2‰ as limit of embedment and the ratio between the ultimate strength and the area of application of load in the specimen for the compressive strength. Afterward, the embedment strength was evaluated by the EUROCEDE 5 /1995 European standard, which use the limit of 5 mm of the displacement for the embedment. Specimens of Pinus oocarpa, Cumaru and Pinus taeda were used in tests to calibration of equipment and specimens of Pinus taeda and Eucalipto citriodora were used to compare the results of strength. The results of strength were evaluated based on statistical analysis. The results of compressive strength for the Pinus taeda showed no significant differences in embedment strength in the directions parallel and normal to the grain. For the Eucalipto citriodora only in the direction parallel to grain the compression strength was not significant compared with the embedment strength. For both species, only the parallel compression strength and inclined at 45o to the grain, which were to the grain, which were admitted the strain of 2‰ were not significantly different compared with the compression strength determined according to ABNT NBR 7190/1997. The normal compression strength obtained according to ABNT NBR 7190/1997 and ultimate compression strength not ...

Criação e implantação de procedimentos logísticos em uma indústria de móveis: estudo de caso

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

Planejamento de uma obra em atendimento às exigências da caixa econômica federal

Currently the Brazilian construction market is growing like gangbusters and every day grows its competition. With this Brazilian scenario, the government is supporting the construction companies and offering resources for real estate projects. To acquire resources Caixa Econômica Federal requirements you must meet in planning the work, as the development of budgets, timelines and memorials. This study aimed to planning a work according to the requirements of Caixa Econômica Federal, which was done with the aid of two softwares . First the methods and tools that are used to perform a planning were discussed. Then, based on the theory and observing the requirements of the financing bank budgets, memorials and schedules with the help of software were performed. At the end of the project, it was possible to observe the importance of using theoretical methods and software to facilitate and improve the timelines and budgets made , and thus the planning itself, which every day becomes more common in construction companies, because with the increase of competition and market requirements, is critical to reducing the loss and time, thus maintaining customer satisfaction and company

Análise da ferramenta LEED para a certificação de edifícios sustentáveis no Brasil

CCurrently there are various systems for the evaluation of environmental impacts of buildings, known as tools of environmental certification. Among these, the tool LEED for New Construction and Major Renovations has been the most widely used and accepted worldwide, in assessing the sustainability of buildings. Therefore, this study aimed to analyze the tool for LEED certification for construction work in Brazil, which ranks fourth in the world ranking records certification of sustainable buildings. It was found in this analysis that the assumptions of this tool are encouraging the use of more sustainable and less impactful on the environment as it promotes the deployment of innovative projects from a technological standpoint, , as well as the valuation of enterprises certified. Also, very significant results obtained in terms of energy efficiency and environmental quality in occupied buildings
