1. Equipments to manage soil and irrigated rice straw for the sequential sowing of soybean in tropical floodplains1
RESUMO A presença de palha dificulta a semeadura de soja cultivada em sucessão a arroz, em áreas irrigadas por inundação. Objetivou-se avaliar a combinação de configurações de colhedora de arroz e operações subsequentes na demanda operacional e energética do manejo da palha de arroz e na rugosidade superficial do solo, visando ao cultivo da soja

3. Desenvolvimento de um sistema de aquisiÃÃo e armazenamento de dados microcontrolado
The data acquisition systems are present in many studies, cooperating on collection, storage and analyses of data. On farming field, these systems are used in experiments of agricultural machines, soil characteristics study, as well as in other applications where data collection by sensors is needed. In the present study, a data acquisition system was develo

4. Evaluation of environment impact of the technological innovation on forest harvesting / Avaliação de impactos ambientais da inovação tecnológica na colheita florestal
In considering the development of forest harvesting in the country, it is observed that the progress was very big. Since the 60 s until the present day there were many changes occurred in this sector, with the operations evolved from a manual process for the semimechanized, became in recent decades a significant aspect in terms of mechanization. Thus, become

5. BALANCEO DE UN SISTEMA DE COSECHA MECANIZADO UTILIZANDO SIMULACIÓN DE EVENTOS DISCRETOS
ABSTRACT A mechanized harvest system was analysed, working in a radiata pine clear cut operation and compound by a feller buncher, a grapple skidder, a grapple processor and a three-wheeler. A Discrete - Event Simulation Model was built with the goal to balance the system. The mechanized wood processing was the bottleneck according to the time study results,

6. Análise técnica e econômica de um sistema de colheita florestal / Technical and economic analysis of a forest harvest system
Hand logging systems were the first adopted, mostly, in the exploitation of native forests, with no concern with the rationalization and productivity of such activities. In Brazil, the first activities of forest harvesting were carried out along the coast, at that time of discovery, when the main traded species was brazilwood. Machine selection and developme

8. Mechanism of locking at the knee joint.
The articular contours of the femoral and tibial condyles show certain basic features that in themselves appear sufficient to effect locking at the knee joint during the terminal stages of extension. The essential feature on the femoral condyles is a convex surface adapted for rolling. On the tibia, the contours that chiefly influence rotation are the concav
