A decade ago, in July 1990, the Australian economy had just entered a severe recession. Real GDP slowed in the first half of 1990, and then began to fall in the second half of the year. The rate of unemployment in mid 1990 was around 63/4 per cent but rose sharply in the following year. The rate of inflation was around 6 per cent, but was about to decline quickly, to levels not seen since the e...

We examined the relationship between thoracic duct lymph flow (TDF) and its driving pressure (DP) in six anesthetized sheep. DP was determined as the thoracic duct pressure (TDP) minus the innominate vein pressure (VP). TDF was measured using an ultrasound transit-time flow meter, placing a flow probe beside the caudal mediastinal lymph node. TDP was measured with a fine needle inserted near th...

Abnormalities of renin release and of venous distensibility have been described in essential hypertension. We have postulated that decreased venous distensibility could contribute to the blunted renin response to upright posture in hypertension. Stiffer veins might prevent venous pooling in the lower extremities, which in turn might affect the stretch on cardiopulmonary mechanoreceptors, thereb...

Estimating the micro-founded New Keynesian Phillips Curve using rational inflation expectation proxies has often found that the output gap is not a valid measure of inflation pressure. This paper investigates the empirical success of the NKPC in explaining US inflation, using observed measures of inflation expectations and taking account of serial correlation in the stylized NKPC. Contrary to r...

N RECENT YEARS, several supply shocks —unusual shifts in production costs —have kept U.S. inflation low by putting downward pressure on prices for certain commodities, especially computers, health care and, until 1996, energy. 1 Because the sectors producing these goods and services are important to the Eleventh Federal Reserve District, these shocks have had an impact on its economy. After exa...

RATIONALE Conventional positive-pressure ventilation delivers pressure to the airways; in contrast, negative pressure is delivered globally to the chest and abdomen. OBJECTIVES To test the hypothesis that ventilation with negative pressure results in better oxygenation and less injury than with positive pressure. METHODS Anesthetized, surfactant-depleted rabbits were ventilated for 2.5 hour...

The breakdown voltage of mineral insulation oil was systematically investigated under the influences of moisture, acidity, pressure and particles. The standards IEC156/95 (VDE0370/Part5/96 and ASTM D1816) specified the test conditions. Moisture provides charge carriers, therefore a moisture saturation of 0 to 20 % decreases the breakdown voltage from 72 down to 61 kV. Acids as aging products de...

Linear increases in G tolerance with increases in anti-G suit (AGS) bladder inflation pressure occurred when relaxed subjects were exposed to acceleration plateaus while riding a centrifuge and were either seated upright, (15 degrees seat back angle or SBA) or supine (60 degrees SBA). Supine G tolerance with AGS bladder inflation decreased as G onset time was increased by factors of two and fou...

The effect of elevated baseline pulmonary vascular pressures on systemic and pulmonary vascular sequelae of prolonged seizures was studied in sheep. Five animals with seizures induced after baseline left atrial pressure elevations of 25 mm Hg were compared with animals treated with seizures alone. Seizure-induced elevations from baseline of systemic and pulmonary vascular pressures were identic...

BACKGROUND Studies have shown that vein size is an important predictor of successful ultrasound-guided vascular access. The objective of this study is to evaluate maneuvers designed to increase basilic vein size, which could be used to facilitate ultrasound-guided peripheral intravenous access (USGPIV) in the Emergency Department (ED) setting. METHODS This was a prospective non-randomized tri...
