Desenvolvimento de requeijão cremoso com baixo teor de lactose produzido por acidificação direta e coagulação enzimática
(Universidade Federal de Santa MariaBRCiência e Tecnologia dos AlimentosUFSMPrograma de Pós-Graduação em Ciência e Tecnologia dos Alimentos, 2011-02-14)
Much of the world population has problems in consuming milk and dairy products because some people are lactose intolerant. To be absorbed in the intestine lactose
needs to be hydrolyzed by lactase enzyme. People with ...
Sedimentation in the coastal reefs of Abrolhos over the last decades
(2013)
Coral reefs of the coastal area of Abrolhos are located in an environment with a high influx of terrigenous sediments that are carried out to the sea, either as a result of natural processes (river output, coastal erosion, ...
Efficiency of zeolite MCM-22 with different SiO2/Al2O3 molar ratios in gas phase glycerol dehydration to acrolein
(2013)
The gas-phase dehydration of glycerol was conducted over MCM-22 zeolite with different SiO2/Al2O3 molar ratios. MCM-22 zeolites were synthesized and characterized by XRD, FTIR, TG, SEM, EDX, textural analysis by N2 ...
The narrow, shallow, low-accommodation shelf of central Brazil: sedimentology, evolution, and human uses
(2013)
The continental shelf off the coast of central Brazil, extending from 10 to 16°S, is unusually narrow (~ 20 km) and rests on the São Francisco craton. The shelf break is located between the 45 and 50 m isobaths and coincides ...
Sm-Nd Age of the Fazenda Brasileiro Gabbro, Bahia, Brazil: Example of Robust Behavior of the Sm-Nd Isotopic System Under Extreme Hydrothermal Alteration
(2003)
The Fazenda Brasileiro gold mineralization is hosted by a gabbroic sill, intrusive into metavolcanicmetasedimentary rocks of the Rio Itapicuru Greenstone Belt, São Francisco Craton. The 2.05 Ga old mineralization
is ...
Multifractal characterization of saprolite particle-size distributions after topsoil removal
(Geoderma, 2006)
Multifractal analysis is now increasingly used to characterize soil properties as it may provide more information than a single fractal model. During the building of a large reservoir on the Parana River (Brazil), a highly ...
Activity of nanocasted oxides for gas-phase dehydration of glycerol
(2011)
A series of nanocasted oxides were synthesised, and an analysis using basicity measurements provided evidence that low strength basic sites with high accessibility favoured the production of 1-hydroxyacetone from glycerol ...
A comparison between the precipitation and impregnation methods for water gas shift catalysts
(2008)
The precipitation and impregnation methods in the preparation of chromium-doped magnetite for water gas shift reaction (WGSR) were compared in this work. This reaction is an important step in the commercial production of ...
A comparison between copper and nickelbased catalysts obtained from hydrotalcitelike precursors for WGSR
(2011)
Nickel or copperbased catalysts were obtained from hydrotalcitelike precursors in this work, in order to find catalysts able to work at intermediates temperatures (200–350 ◦C) in water gas shift reaction
(WGSR). Samples ...
The Itiúba alkaline syenite massif, Bahia State (Brazil): mineralogical, geochemical and petrological constraints—relation to the genesis of rapakivi magmatism
(Precambrian Research, 1991)
Numerous alkaline massifs occur throughout the state of Bahia (Brazil). Isotopic dates fall into two age groups: Brasiliano (0.45–0.70 Ga) and Trans-Amazon (1.8–2.1 Ga) ones. Brasiliano alkaline provinces comprise a ...
