Mechanical and rheological properties of partial replacement of carbon black by treated ultrafine calcium carbonate in natural rubber compounds
(2021-01-01)
The present research aimed to develop natural rubber hybrid composites reinforced with treated ultrafine calcium carbonate/carbon black (CC/CB). The influence of CC/CB with various filler ratios (50/0, 40/10, 30/20, 20/30, ...
Modern non-tropical mixed carbonate-siliciclastic sediments and environments of the southwestern Gulf of California, Mexico
(Sedimentary Geology, 2004)
Modern mixed carbonate-siliciclastic warm-temperate environments were studied in the southern Gulf of California (GOC), Mexico. The combined heterozoan and photozoan character is defined by the absence of true coral reef ...
Soil carbon as affected by cover crops under no-till under tropical climate
(Wiley-Blackwell, 2016-12-01)
In tropical, low-fertility soils, crop yields are dependent on soil carbon, and cropping systems under no-till can increase soil C stocks. Plant residues supplied by cover crops in no-till systems may improve aggregate ...

Carbon isotope fractionation during calcium carbonate precipitation induced by urease-catalysed hydrolysis of urea
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Stable carbon isotopic fractionation during calcium carbonate precipitation induced by urease-catalysed hydrolysis of urea was experimentally investigated in artificial water at a constant temperature of 30 degrees C. ...
Ediacaran paleoenvironmental changes recorded in the mixed carbonate-siliciclastic Bambui Basin, Brazil
(Elsevier B.V., 2019-03-01)
Significant Ediacaran paleoenvironmental changes recorded in the mixed carbonate-siliciclastic Bambui Basin, east-central Brazil, outcrop in one of the best-preserved sites, the Januaria paleo-high. From a detailed strati ...
Valuing the economic impacts of seed dispersal loss on voluntary carbon markets
(2021-12-01)
Seed dispersal is an ecosystem service strongly affected by the loss of mutualist dispersers, with economic consequences in terms of carbon sequestration and climate change mitigation policies. Especially, large frugivores ...

Carbon Stocks and Isotopic Composition of the Organic Matter in Soils Covered by Native Vegetation and Pasture in Sorocaba, SP, Brazil
(Univ Tehran, 2009-06-01)
Land cover change constitutes one of main way of alteration of soil organic matter in both quantitative and qualitative terms. The goal of this study was to compare the carbon stock and the isotopic signature of the organic ...
