Fourteen healthy elderly men had polysomnography performed on two consecutive nights to assess the consistency of sleep and breathing from night to night. The reported first-night effect was seen on electroencephalographic sleep, leading to lighter or fitful sleep on the first night. Mean values for apneas, hypopneas, and oxygen desaturations did not change from night 1 to night 2. Five of 14 s...
OBJECTIVE To explore the night-waking schemas of mothers of preschool-aged children, using a new measure of agreement with night-waking strategies (Night-waking Vignettes Scale; NVS). METHOD A community sample of 203 mothers (M age = 32 years, SD = 5.1) of 2- to 5-year-olds (M age = 3.4 years, SD = 1.0) provided demographic information and completed the NVS and measures of night-waking and ge...
introduction: in modern societies, shift work is an essential component of daily life. since the beginning of research in shift work, researchers have been engaged in the identification of factors predicting adjustment and adaptation to shift work. the concept of adaptation and tolerance refers mainly to the biological response in terms of circadian rhythms and performance efficiency as well as...
Social Indicators for Aboriginal Governance: Insights from the Thamarrurr Region, Northern Territory
Nowadays, pedestrian recognition in far-infrared images toward realizing a night vision system becomes a hot topic. However, sufficient performance could not be achieved by conventional schemes for pedestrian recognition in farinfrared images. Since the properties of far-infrared images are different from visible images, it is not known what kind of scheme is suitable for pedestrian recognition...
The visual effects of repeated exposure to carbon dioxide (C02) at levels commonly regarded as innocuous were investigated. Exposure to C02 varied cyclically from .03 (air) to 3.0%, at one atmosphere pressure, every 24 hours for a period of six days. A battery of visual tests was administered during this period and in control periods both before and after the exposure to carbon dioxide. Among t...
A design approach is described to achieve spectral blocking filters of any spectral width and optical density for narrow blocking bands. The ratio of the thickness of the high-index material to the low-index material in the layer pairs is adjusted to obtain the desired bandwidth in the first-harmonic reflection band. The number of layer pairs is adjusted to provide the required optical density....
