BACKGROUND This work aimed to compare frequency of blood gas measurements per day of mechanical ventilation, occurrence of extreme blood gas CO2 values, and clinical outcomes among ventilated neonates managed with and without transcutaneous carbon dioxide (PtcCO2) monitors. This work also measures agreement between simultaneous PtcCO2 and blood gas CO2 measurements and ascertains factors that a...

Nine children had simultaneous continuous electroencephalographic monitoring and temperature recording immediately after febrile convulsions. Background electroencephalographic rhythms did not alter with temperature and with one exception, seizure discharges occurred only during sustained high pyrexia.

Performing two cognitively demanding tasks at the same time is known to decrease performance. The current study investigates the underlying executive functions of a dual-tasking situation involving the simultaneous performance of decision making under explicit risk and a working memory task. It is suggested that making a decision and performing a working memory task at the same time should part...

To determine the suitable indices for vegetation cover and production assessment based on the remote sensing data, simultaneous digital data with field data belonging to the spring rangeland of the Semirom-Isfahan province were analyzed. During two years of monitoring the annual, grass, forb, and shrub vegetation cover and the total production data from 86 were collected. The Global Positioning...

Common problems in the analysis of environmental monitoring data are nonnormal distributions (i.e., right skewed such as gamma and lognormal) and the presence of moderate to large numbers of nondetects (i.e., data below a detection or quantification limit). When new monitoring measurements are compared to background (e.g., comparison of a new downgradient ground water measurement to a series of...
