Thermal degradation of geomembranes after exposure to heat
(Millpress Science Publishers, 2006-01-01)
HDPE and PVC geomembranes are sensitive to changes in their properties when in contact with high temperatures. The effects of hot temperature on polymeric geomembranes are assessed by the ASTM D794 and ASTM D5721.This paper ...
Prediction of dry matter intake based on ruminal degradation from milking cows grazing coast-cross grass
(Fundação Estudos Agrarios Luiz Queiroz (fealq), 2001-01-01)
Dry matter intake (DMI) of coast-cross grazing by crossbred Holstein-Zebu and Zebu lactating cows was calculated using in vitro dry matter digestibility from extrusa (four esophageal fistulated cows) and fecal output ...
Indicators of soil degradation in urban forests: Physical and chemical parameters
(2012-10-15)
The fragmentation of forest habitats in urban areas has aroused increasing interest in recent years according to the growing environmental problems. The fragmentation of theses ecosystems is caused, in general, by the ...
UV degradation of HDPE and pvc geomembranes in laboratory exposure
(2010-01-01)
This article evaluates the effects of UV degradation in HDPE geomembranes that were exposed both in laboratory and outdoor conditions. The laboratory tests were performed using a weatherometer assembled at EESC-USP in ...
