1. Soil Water Retention Curve as Affected by Sample Height
ABSTRACT: The soil water retention curve is one of the main instruments to assess the soil physical quality and to improve soil management. Traditionally, the equipment most used in the laboratory to determine the retention curve has been Haines funnels and Richards chambers. An important factor to which little attention has been given in the use of these eq

6. Comportamento do hidrociclone filtrante frente às modificações no diâmetro de underflow e no tubo de vortex finder
Filtering hydrocyclones are similar equipaments to the conventional hydrocyclone except by the fact they have filtering conical region. In this way, during the operation of this equipament, besides the feed streams, the underflow and the overflow, observed commonly, the porous conical region produces liquid by the filtration process. The filtration in the co
