Determinación de esfuerzos IN-SITU y presión de fractura mediante la técnica de inversión
(2020-03-05)
RESUMEN: El conocimiento del estado de esfuerzos in-situ es de gran importancia para el estudio de la estabilidad de pozos petroleros, porque permite entender los factores que controlan la generación de fallas en la pared ...
Simultaneous and highly sensitive determination of selenium and tellurium species in environmental samples by on-line ionic liquid based in-situ solvent formation microextraction with hydride generation atomic fluorescence spectrometry detection
(Elsevier Science, 2021-01)
A novel on-line preconcentration and speciation analysis method for the simultaneous determination of inorganic Se and Te species is presented in this work. The methodology is based on the on-line formation of a hydrophobic ...
Estudo do processo de combustão in-situ em reservatórios maduros de óleos médios e leves (high pressure air injection)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2013-07-29)
Nearly 3 x 1011 m3 of medium and light oils will remain in reservoirs worldwide after
conventional recovery methods have been exhausted and much of this volume would be
recovered by Enhanced Oil Recovery (EOR) methods. ...

O uso de peixes em estudos experimentais ecotoxicológicos "in situ", avaliando os efeitos da poluição aquática urbana em reservatórios
(Universidade Federal de Minas GeraisUFMG, 2016-02-03)
Experimental studies ecotoxicological in situ are used to demonstrate the effectiveness of using fish as an environmental assessment tool in biomonitoring programs. In this thesis are shown researches and concepts of how ...
Multifilamentary MgB2 Wires Prepared by an In Situ Powder-in-Tube Method
(Springer/Plenum Publishers, 2015-04-01)
MgB2 has become a commercially attractive material for technological applications for its particular superconducting properties. However, due to its brittleness to obtainwires, a metallic sheath is needed for drawing. In ...
