Objective: To determine whether the use of a gel pillow with side cutouts designed to accommodate a continuous positive airway pressure (CPAP) mask and reduce head temperature improves the efficacy of and adherence to auto-CPAP therapy. Methods: Twenty-three consecutive CPAP-naïve patients with obstructive sleep apnea were enrolled in the study. Patients were given an auto-CPAP machine with a...

The mainly deep-submarine Ontong Java Plateau (OJP) is the result of largest outpouring lava in geologic record. Volcanic events this magnitude can have dramatic environmental impacts due to volatile emissions. We report new S measurements naturally glassy, olivine-hosted melt inclusions and pillow basalt glasses from OJP. combined these data with previous OJP quantify degassing a suite glasses...

Late Ediacaran rocks of the Ouarzazate Group define a thin pile sediments and pyroclastic deposits between Paleoproterozoic basement Cambrian sedimentary cover in southern Kerdous Tagragra d’Akka inliers. In Tafeltast area, terrigenous with volcano-sedimentary are located grabens controlled by syn-sedimentary normal faults. The sedimentation is characterized maximum flooding outlined Agoujgal c...

River channels and valleys have been observed on several planetary bodies in addition to the Earth. Long sinuous valleys on Venus, our Moon and Jupiter's moon Io are clearly formed by lava, and branching valleys on Saturn's moon Titan may be forming today by rivers of methane. But by far the most dissected body in our Solar System apart from the Earth is Mars. Branching valleys that in plan res...

We report on spectral reflectance measurements of basaltic lava flows on Tenerife Island, Spain. Lava flow surfaces of different ages, surface roughness and elevations were systematically measured using a field spectroradiometer operating in the range of 350–2500 nm. Surface roughness, oxidation and lichen coverage were documented at each measured site. Spectral properties vary with age and mor...

BACKGROUND Neck flexion by head elevation using an 8 to 10 cm thick pillow and head extension has been suggested to align the laryngeal, pharyngeal and oral axis and facilitate tracheal intubation. Presently, the laryngeal view and discomfort for tracheal intubation were evaluated according to two different degrees of head elevation in adult patients. METHODS This prospective randomized, cont...
