The ability of vehicles to traverse soft soils is an important aspect of their performance. The geological, climate and topography diversity originated, in Rio Grande do Sul, extensive areas of hydromorphic clay soils, as example, Planssoils and Gleissoils. When saturated of water, these soft soils present low loads support, difficult agricultural machinery work and limit the traverse of military wheeled vehicl...
O presente artigo descreve as acções empreendidas no âmbito de um projecto de investigação em Portugal para realizar a medição das vibrações geradas pelo tráfego de comboios, em particular os comboios de alta velocidade. Neste contexto estão em curso campanhas de medição de vibrações com recurso a acelerómetros na Linha do Norte, onde são instrumentadas secções com diferentes características geométricas e geoté...
The adoption of precision agriculture techniques finds great limitation because of the high cost, not always guaranteeing the expected economic return. Among the consequence of this elevated cost it is the restriction use of this technology in small farmers, characterized by the family farm. The present work approaches a bibliographical study about the situation of the family farm in Brazil, pointing to regiona...
