T e crop water stress index (CWSI), developed at the USDA-ARS [LS. Water Conservation Laboratory, Phoenix, Arizona, is a commonly used index for detection of plant stress based on the difference between foliage and air temperature. Application of CWSI at local and refzional scales has been hampered by the difficulty of measuring foliage temperature of partially vegetated fields. Most hand-held,...

OBJECTIVES To assess and compare the effect of nasal continuous positive airway pressure (nCPAP), inspiratory pressure support (PSV), and bilevel positive airway pressure (biPAP) on ventilatory parameters and inspiratory work (WOB) in normocapnic and hypercapnic patients with stable COPD. METHODS While administering nasal pressure support to 10 normocapnic and 10 hypercapnic patients with COP...

We investigate the implications of the new price information in the latest International Comparison Program (ICP) survey for evaluating the year 2005 exchange rate misalignment estimates. A decomposition exercise reveals that the misalignment revisions are substantially affected by the ICP price updates. Two measurement-related and four economic factors are used to explain the differences in mi...

[Purpose] This study set out to substantiate the importance of the right sitting posture by measuring the sitting pressure. It also described the influence of an imbalanced sitting posture on the body. [Subjects and Methods] The subjects included 30 healthy adults. A pressure mapping system was used to measure the sitting pressure in the right, one side prone, chin propped, and slumped sitting ...

A global poverty map has been produced at 30 arcsec resolution using a poverty index calculated by dividing population count (LandScan 2004) by the brightness of satellite observed lighting (DMSP nighttime lights). Inputs to the LandScan product include satellite-derived land cover and topography, plus human settlement outlines derived from high-resolution imagery. The poverty estimates have be...
