Thermal structure, heat content and stability of two lakes in The National Park of Rio Doce Valley (Minas Gerais, Brazil)
(1989-02-01)
The thermal structure, heat content and stability were studied in Lakes Dom Helvécio and Carioca during an annual cycle. It was found that the maximum heat content, stability and work of the wind in Lake Dom Helvécio ...
The effect of silo milk composition parameters on heat stability of whole milk powder
(Sage Publications Ltd, 2004-03)
The aim of this work was to study silo raw milk (SRM) compositional parameters that affect the heat stability of whole milk powder (WMP). Seasonal changes of heat stability from SRM and WMP were also characterised. Silo ...
Peroxidase from peach fruit: Thermal stability
(Inst Tecnologia Parana, 1998-01-01)
Peroxidase from peach fruit was purified 28.9-fold by DEAE-cellulose, Sephadex G-100 and hydroxylapatite chromatography. The purified enzyme showed only one peak of activity with an optimum pH of 5.0 and temperature of 40 ...
Partial purification, heat stability and kinetic characterization of the pectinmethylesterase from Brazilian guava, Paluma cultivars
(Elsevier B.V., 2006-03-01)
Pectinmethylesterase (PME) was extracted from guava fruit (Psidium guajava L.), cultivar Paluma, by 70% ammonium sulphate saturation and partially purified by gel filtration on Sephadex G100. Gel filtration showed PME ...
Synthesis and structural evolution of partially and fully stabilized ZrO2 from a versatile method aided by microwave power
(2018-02-15)
We propose a simple, fast, and economical method to obtain ZrO2 powders aided by microwave heating. Partially stabilized zirconia (tetragonal+monoclininc) undergoes transition to fully stabilized zirconia in the tetragonal ...
