Palm heart harvesting in the Brazilian Atlantic forest: changes in industry structure and the illegal trade

1. Until the late 1960s, Euterpe edulis was the most important edible palm species in the Brazilian markets. Since then, overharvesting of natural stands and the limited scope of plantations have caused the industry to shift to the multistemmed E, oleracea from the Amazon river estuary.2, As a result of the relocation of the industry, the structure of the palm harvesting industry has changed and illegal trade has continued to exploit the remaining natural stands of E, edulis.3, it is suggested that, to avoid the total harvesting of E. edulis and to achieve sustainable management of the palm heart, it will be necessary to diversify the local economy, create incentives for small land owners to improve their management practices, while keeping their competitiveness against the illegal trade, create the incentive of new sources of palm hearts and create a 'green stamping' For management palms.4, Transformation of the illegal structure of the palm heart industry is probably the only solution to avoid the total depletion of the wild stands of E. edulis.

Fabricação de rodas: uma análise comparativa

In our country, the majority of freight and people by road happens municipal, state and federal. Thus, the heavy vehicles like buses and trucks are the main means of transporting people and cargo. This graduate work aims to study the process of manufacturing wheels for trucks, because we can see the lack of literature on the manufacturing process of wheels and also the importance of the processes used to manufacture wheels, such as lamination, stamping, puckering, machining, welding and painting

Caracterização do defeito tipo trinca de laminação, ocorrido no processo de laminação de barras de aço

The mechanical forming processes are the main means of transformation. Among all processes, the most used is rolling and broken down into flat and non-flat products. In the flat products are classified plates, and products no plans bars and profiles. Thus laminating products, mostly, are the raw materials for other processes of transformation, as stamping, forging, machining, bending and more. This work has focused on non-flat products, classified as bars and rods, watching a key point in the proceedings that is the product quality. Here is demonstrated through metallographic analysis of steel bars, hot-rolled, the characteristics of surface cracks in these bars

Difusão de tecnologia CAD e CNC como ferramenta básica de criação e produção em pequena escala, acessível à comunidade

The high competitiveness and the search for newtechnologies that differentiate the product from the project,require the use of new digital tools. The computer aideddesign - Computed Aided Design (CAD), with electronicmodeling, simulation, structural analysis and production,performed in a virtual environment through the applicationof specific software, are available but their use is stilllimited. There are various software available in languagesand extensions to industrial production which, from 3Dmodeling, they can manage through Computer NumericalControl - Computed Numerical Control (CNC) machiningcenters, laminating, stamping, mold making and otherprocesses productive. This project aims to encouragecreativity and entrepreneurship in the community throughthe provision of technology computer aided design - CAD,with a view to implementation of machining technology.
