Enhanced photocatalytic activity of silver vanadate nanobelts in concentrated sunlight delivered through optical fiber bundle coupled with solar concentrator
(Springer, 2020-02-01)
To date, sunlight driven photocatalytic process for wastewater treatment is a great challenge. Herein, the photocatalytic methylene blue (MB) dye degradation activity of silver vanadate nanobelts has been enhanced using ...
Effects of pH and sugar concentration in Zygosaccharomyces rouxii growth and time for spoilage in concentrated grape juice at isothermal and non-isothermal conditions
(Elsevier, 2013-09)
The effect of pH (1.7–3.2) and sugar concentration (64–68 °Brix) on the growth of Zygosaccharomyces rouxii MC9 using response surface methodology was studied. Experiments were carried out in concentrated grape juice ...
Suspension and infiltration of copper concentrate in a gravel bed: a flume study to evaluate the fate of a potential spill in a Chilean river
(Springer, 2020)
This paper shows the advances of an experimental study of the spill of copper concentrate into immobile gravel beds. The purposes of this research are to identify the dynamics of the copper concentrate as it spills in ...
Elevation of boiling point of coffee extract
(2002-01-01)
The rise in boiling point of coffee extract was experimentally measured at soluble solids concentrations in the range of 9.2 to 52.4°Brix and pressures between 5.8 × 103 and 9.4 × 104 Pa (abs.). Different approaches to ...
Mineral salt intake effects on faecal-N concentration and the volume and composition of beef cattle urine
(2018-01-01)
The effect of mineral salts on water ingestion and urine volume in cattle has been extensively studied. However, recently, this effect has been investigated as a potential mitigator of environmental aspects related to the ...
Effect of fine-scale spatial variation of soil nitrogen on the performance of the sexes of Poa ligularis in patchy ecosystems of northern Patagonia
(University of Chicago Press, 2002-06)
In patchy environments of arid Patagonia, males of the dioecious grass Poa ligularis dominate in N-poor microsites, while females are more common in N-rich microsites. In order to explore functional differences related to ...
Effect of thermal pasteurization and concentration on carotenoid composition of Brazilian Valencia orange juice
(Elsevier B.V., 2007-01-01)
Changes in carotenoid pigment content of Brazilian Valencia orange juices due to thermal pasteurization and concentration were studied. Total carotenoid pigment content loss was not significant after thermal pasteurization ...
