1. Analysis of the characteristics of the wood and the candeia essential oil - Eremanthus erythropappus (DC.) Macleish, of the region of Aiuruoca, MG / Análise das características da madeira e do óleo essencial de candeia - Eremanthus erythropappus (DC.) Macleish, da região de Aiuruoca, MG.
Forests have been fundamental as a source of several basic necessities of the human being, as shelter, clothes, nourishment, energy etc. In this context, essential oils have had an important role, either in the national or in the international scene. Many forest species have the potential for oil extraction and, amongst these, candeia (Eremanthus erythroppap

2. Caracterização fisico-química de adobe estabilizado com amido de mandioca
Due to the high habitational Brazilian shortage, traditional technologies of earth construction and constructive elements production have been rescue, having the soil as a principal raw material. Between these traditional technologies, there are the adobes, which consist of soil blocks with regional variable size. The soil material is removed, humidified, tr

3. Measuring moisture content in concrect-wood system / Medição da umidade no sistema concreto-madeira
A aplicação de um piso de madeira maciça sobre um contrapiso de concreto dá origem a um sistema que une dois materiais com diferentes características higroscópicas, e no qual a movimentação da umidade é ainda um fenômeno pouco conhecido. Visando um melhor entendimento desse fenômeno, a presente pesquisa buscou avaliar diferentes equipamentos para

6. Collapse of Water-Stress Emboli in the Tracheids of Thuja occidentalis L.
We report the kinetics of embolus formation and collapse in the tracheids of Thuja occidentalis L. stem segments. Radial wood sections were trimmed to 4 mm long paralleling the tracheids by 1 mm wide and 0.1 mm thick. They were observed under a dissecting microscope at 128x while sections were dehydrated and rehydrated. During dehydration, cavitations result
