Spectroscopic study of lanthanide squarate hydrates
(1994-12-01)
In the present investigation some spectroscopic properties of several lanthanide squarate hydrates are reported. The Raman spectra show the same distinctive Jahn-Teller intensity pattern for non-totally symmetric modes, ...

Citric acid as anti-hydration additive for magnesia containing refractory castables
(ELSEVIER SCI LTD, 2011)
Magnesia hydration is a key concern in refractory castable processing. The volumetric expansion that follows this reaction can result in cracks or even explosion during the first heating-up. Citric acid (CA) and other ...
Study of gas hydrate formation and wall deposition under multiphase flow conditions
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2017-05-05)
Potential flow assurance problems in oil and gas pipelines related to gas hydrates have traditionally been resolved by implementing hydrate avoidance strategies, such as water removal, insulation, and injection of thermodynamic ...
Effect of maternal hydration on the increase of amniotic fluid index
(Associação Brasileira de Divulgação Científica (ABRADIC), 2011-03-01)
The objective of this study was to determine the effect of maternal hydration with oral isotonic solution and water on the amniotic fluid (AF) index of women with normohydramnios. Women with a normal AF index and gestational ...
