The oldest abundant volcanic glass on Earth occurs in a Carboniferous ignimbrite in the region of Port Stephens, NSW. The K‐Ar age of 332 ± 4 Ma on biotite is consistent with the geological relations and establishes a Carboniferous age for the gla

A seven-stage low-pass digital filter was used to remove the cardiac artifact and motion interference from a respiratory transthoracic impedance signal in human subjects. After removal of these artifacts, the mean difference from a conventional gasom

The primary purpose of this study was to determine the effect of acute (20–30 min) elevations of inspired CO2 partial pressure (PICO2) on whole-body O2 consumption (VO2). In human subjects, VO2 increased approximately 15 ml.min-1.m-2 with each 7-To

The purpose of these studies was to gain insight into mechanisms regulating pulmonary ventilation (VE), arterial CO2 partial pressure (PaCO2), and arterial pH (pHa) in ponies when inspired CO2 partial pressure (PICO2) is above normal. Ponies were stu

In order to determine the ability of single-breath nitrogen closing volume (CV) to detect early airway obstruction, the CV was measured in patients with either minimal obstruction of spirometry or with increased residual volume (RV). A total of 39 su

In a survey of 75 dancers (mean age, 24.3 years) in four professional ballet companies, we found that the prevalence of scoliosis was 24 percent and that it rose with increases in age at menarche. Fifteen of 18 dancers (83 percent) with scoliosis had

Thoracic impedance changes have been used to measure tidal volume and ventilation in normal subjects. Tidal volume was measured directly and total ventilation was accumulated with a diode voltage pump. The size, shape, and placement of the electrodes

Graphite in a contact metamorphic aureole around adamellite at Undercliff, northern New South Wales, contains fossil leaves of the Glossopteris flora. Investigations by differential thermal analysis, X‐ray diffraction, chemical analysis, and electr
