Oxygen reaction-diffusion in metalorganic chemical vapor deposition HfO/sub 2/ films annealed in O/sub 2/
(2002) [Artigo de periódico]Composition, atomic transport, and chemical reaction were investigated following annealing in O2 of ultrathin HfO2 films deposited on Si substrates thermally nitrided in NO. The as-prepared thin film composition was ... -
Oxygen species in HfO/sub 2/ films : an in situ x-ray photoelectron spectroscopy study
(2007) [Artigo de periódico]The chemical bonding of O atoms in HfO2 films on Si was investigated by in situ x-ray photoelectron spectroscopy in the O 1s spectral region. In addition to trivial O forming only O-Hf bonds, O 1s signals corresponding to ... -
Oxygen transport and GeO2 stability during thermal oxidation of Ge
(2012) [Artigo de periódico]Oxygen transport during thermal oxidation of Ge and desorption of the formed Ge oxide are investigated. Higher oxidation temperatures and lower oxygen pressures promote GeO desorption. An appreciable fraction of oxidized ... -
Oxygen transport and incorporation mechanisms in the dry thermal oxidation of 6H-SiC
(2004) [Artigo de periódico]Thermal oxidation of 6H-SiC was investigated by means of isotopic tracing and narrow nuclear resonant reaction profiling techniques. The mechanisms of oxygen transport and incorporation were accessed by sequential oxidations ... -
Oxygen transport and reaction mechanisms in rhenium gate contacts on hafnium oxide films on Si
(2006) [Artigo de periódico]Oxygen transport and incorporation were investigated following postdeposition annealing of metal-oxide-semiconductor structures having ultrathin rhenium films as metal electrode and HfO2 films as dielectric on Si 001 . ... -
Oxygen uptake in water polo, comparison and agreement in cycle ergometer and eggbeater kick : a pilot study
(2016) [Artigo de periódico]The aim of this study was to compare and verify the agreement of maximal oxygen uptake (VO2 max) values obtained from tests on land and in water. Twelve recreational water polo players (30.5 ± 7.7 years; 79.2 ± 7.2 kg body ... -
Oxytocin and arginine vasopressin receptor evolution : implications for adaptative novelties in placental mammals
(2016) [Artigo de periódico]Oxytocin receptor (OXTR) and arginine vasopressin receptors (AVPR1a, AVPR1b, and AVPR2) are paralogous genes that emerged through duplication events; along the evolutionary timeline, owing to speciation, numerous orthologues ... -
Oxytocin and arginine vasopressin systems in the domestication process
(2018) [Artigo de periódico]Domestication is of unquestionable importance to the technological revolution that has given rise to modern human societies. In this study, we analyzed the DNA and protein sequences of six genes of the oxytocin and arginine ... -
OzDES multifibre spectroscopy for the Dark Energy Survey : 3-yr results and first data release
(2017) [Artigo de periódico]We present results for the first three years of OzDES, a six year programme to obtain redshifts for objects in the Dark Energy Survey (DES) supernova fields using the 2dF fibre positioner and AAOmega spectrograph on the ... -
OzDES multi-object fibre spectroscopy for the Dark Energy Survey : results and second data release
(2020) [Artigo de periódico]We present a description of the Australian Dark Energy Survey (OzDES) and summarize the results from its 6 years of operations. Using the 2dF fibre positioner and AAOmega spectrograph on the 3.9-m Anglo-Australian Telescope, ... -
p14 expression differences in ovarian benign, borderline and malignant epithelial tumors
(2016) [Artigo de periódico]Background: Abnormalities in tumor suppressors p14, p16 and p53 are reported in several human cancers. In ovarian epithelial carcinogenesis, p16 and p53 show higher immunohistochemical staining frequencies in malignant ... -
P2X7 receptor contributes to long-term neuroinflammation and cognitive impairment in sepsis-surviving mice
(2023) [Artigo de periódico]Introduction: sepsis is defined as a multifactorial debilitating condition with high risks of death. The intense inflammatory response causes deleterious effects on the brain, a condition called sepsis-associated encephalopathy. ... -
