1. Erratum
Abstract Bauxite mining has been carried out around Poços de Caldas, Minas Gerais, since the 1940s. Companies operating in the region pioneered land rehabilitation in Brazil, conducted since the early 1980s. Different procedures of recontouring, runoff drainage, soil preparation and vegetation planting were employed. This research aims to evaluate current e

4. Soil conservation practices in a watershed in Southern Brazil
Abstract: The aim of this study was to determine how often rural farmers in a watershed use no-tillage systems combined with crop rotation, contour farming and agricultural terraces. The study area was Paraná Watershed III (PB3) in the western region of Paraná State, and data from the 2006 Agricultural Census of the Brazilian Institute of Geography and Sta

5. Water dynamics in level terraces. / Dinâmica da água em terraços de infiltração.
Terracing is a soil conservation practice that aims to reduce water and soil loss by interception of runoff that occurs when rainfall intensities exceed infiltration capacity. Actually, dimensions of terraces are being determined in an empirical way; however, a more detailed understanding of the physics behind the hydrological functions of terraces would all

6. Análise da erosão do solo usando a EUPS, através de técnicas de sensoriamento remoto e geoprocessamento / Soil erosion analysis, using the USLE, using both remote sensing and geoprocessing techniques
The Universal Soil Loss Equation (USLE) has been used within geographical information systems targeting the development of means of producing basic planning information. Remote sensing data have been used to map the most dynamic side of erosion: land use and management. Overestimations of erosion and Natural Erosion Potential have been regularly obtained, th

7. Periodic phenomena in Proteus mirabilis swarm colony development.
Proteus mirabilis colonies exhibit striking geometric regularity. Basic microbiological methods and imaging techniques were used to measure periodic macroscopic events in swarm colony morphogenesis. We distinguished three initial phases (lag phase, first swarming phase, and first consolidation phase) followed by repeating cycles of subsequent swarming plus c
