The effect of the fluorination of aluminum oxide (Al2O3) in an oxide-nitride-aluminum oxide (SiO2-Si3N4-Al2O3, ONA) layer through fluorine (F) ion and neutral-beam treatments on the characteristics of the ONA layer was investigated to study the effect of charge-related damage during F ion beam treatment. The treatment with an F beam at approximately 10 eV energy produced an about-5-nm-thick fluorinated alumina layer by replacing the aluminum-oxygn (Al-O) bonding with Al-F bonding for both the F neutral-beam and F ion beam treatments...

The genus Oxygyne comprises three species disjunctly distributed in Africa and Japan and is the least examined genus of the Burmanniaceae due to the scarcity of living material. We obtained living samples of Oxygyne shinzatoi and examined the phylogenetic position of this species on the basis on the 18S rDNA sequence. Oxygne shinzatoi was consistently found to belong to the monophyletic group of tribe Thismieae, but its position in the tribe differed depending on the criteria applied (maximum parsimony, maximum likelihood, Bayesian inference)...

This study was carried out on 30 critically ill patients admitted to the ICU of Farwania Hospital (Kuwait). All patients had clinical evidence of organ dysfunction or impending multiple organ failure. The severity of their pathology on admission was assessed according to the APACHE II score. The study of each patient began after inserting the pulmonary artery catheter. The prospectively defined end-point of the study was the removal of the pulmonary artery catheter (72 hours) or death of the patient with the catheter in situ...

Cardiorespiratory, thermal, and renal responses to a 30-min head-out immersion in 15 degree C water were studied at 1-ATA air and 11-ATA helium-oxygne environments in four male subjects wearing dry suits. Cardiorespiratory responses to immersion (reductions in heart rate, expiratory reserve volume, vital capacity, and thoracic impedance; and increases in stroke volume, cardiac output, and inspiratory capacity) were comparable at both pressures. However, thermal responses to immersion (a reduction in mean skin temperature and increases in skin heat flux and suit conductance) were significantly greater at 11 ATA compared to those at 1 ATA...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
