1. Particleboard manufactured from Tauari (Couratari oblongifolia) wood waste using castor oil based polyurethane resin
Several wood species from the Amazon region are used in the manufacture of furniture, which leaves behind large amounts of waste (slabs, sawdust, sanding dust and bark), thus causing serious environmental impacts. An interesting alternative for the use of these wastes is the manufacture of particleboards. However, few studies have focused on the behavior of

2. Desenvolvimentos mecânicos e computacionais de suporte às medidas com sensores termoelásticos
The hydrostatic pressure inside the cell or simply cell turgor is an important component of texture in vegetables and is directly related to firmness. The decrease in cell turgor of plant organs is also an indicator of loss of tissue water. This effect can be perceived visually by wilting accompanied by a dry appearance with the loss of brightness and color

3. MODELOS DE CRESCIMENTO DE QUATRO ESPÉCIES MADEIREIRAS DE FLORESTA DE VÁRZEA DA AMAZÔNIA CENTRAL POR MEIO DE MÉTODOS DENDROCRONOLÓGICOS
Timber harvesting is an important economic activity in nutrient-rich floodplain forests (várzea) of Central Amazonia. In the Western Amazon basin of Brazil and Peru, access to terra firme forests is restricted due to the absence of a road network. Still, 6090% of the local and regional markets are provided with timber obtained from the floodplain forests. C

4. Caracterização da integridade de superfícies usinadas para produção de moldes e matrizes
Este trabalho abrange o estudo do processo convencional de fabricação de moldes e matrizes, ou seja, passando por processos de fresamento, eletroerosão e lixamento. Estes três processos foram aplicados ao material AISI H13, usualmente empregado na fabricação de moldes e matrizes. Além disso, foram variadas condições de usinagem, como o uso de fluíd

5. Métodos de Valoração Econômica Ambiental e Danos Ambientais Causados pela Bovinocultura de Corte
Agribusiness has been o fundamental importance to the economy of Brazil and Mato Grosso do Sul. The surprising success of Brazilian agro-animal husbandry production has revealed its immense potential in this area, shown by its figures. However, over the last decades, the environment has been suffering negative impacts as a result of human activities, such as

6. Evolução morfodinâmica da região de influência estuarina do Rio Curimataú/RN, com ênfase nas alternativas do ambiente deposicional de manguezal e a integração de geodados em Sig
The estuaries are important investigation zones of the actual morphodynamic and of depositional facies of recent geological history. They are constituted in important receptor means of the coastal area sediments, where the evolutionary processes occur quickly. They are also attractive means for the development of anthropic activities, which in a disordered w
