Sudden Deaths Due To Accidental Intravenous Injection Of Perfluorocarbon During Mri Cranial Examinations
(Springer-Verlag Tokyo, 2014)
Effect of casting atmosphere on the shear bond strength of a ceramic to Ni-Cr and Ni-Cr-Be alloys
(Fundação Odontológica de Ribeirão Preto, 2009)
The success of metal-ceramic restorations depends on an optimal bond between metal and ceramic. This study evaluated the effect of 3 casting atmospheres on the metal-ceramic bond strength (MCBS) of 2 Ni-Cr alloys, with ...
Tribological study of high bearing blended polymer-based coatings for air-conditioning and refrigeration compressors
(Elsevier, 2011-01)
Deposition by spray techniques has made possible to coat different substrate materials found in engineering applications, such as air-conditioning and refrigeration compressors, with blended soft polymeric coatings based ...

RESUMEN: En esta tesis se ha estudiado la eficiencia de dos resinas de acabado, basadas en fluorocarbono. Para analizar la influencia de concentración de resina, se han ensayado tres concentraciones para cada resina. Por ...
Análise de desempenho de um refrigerador de pequeno porte com drop in de refrigerantes hidrocarbonetos
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2010-12-20)
From what was stated in the Montreal Protocol, the researchers and refrigeration industry seek
substitutes for synthetic refrigerants -chlorofluorocarbons (CFCs) and HCFCs (HCFC) - that
contribute to the depletion of the ...
Molecular dynamics methodology for the evaluation of the chemical alteration of wettability of sandstones
(2018-04-17)
A common practice in the petroleum industry is the waterflooding or another liquids into the formation, to extract the hydrocarbon contained in small pores, through of enhanced/recovery methods (IOR/EOR). In processes of ...
