In an earlier published telephone interview study (n . 1,000) we have shown that retired shift workers subjectively report worse sleep than retired day workers. This laboratory study sought to determine whether these findings held up when objective polysomnograhic (PSG) measures of sleep were taken and whether retirees’ circadian temperature rhythms differed as a function of shift work exposure...

Heat stress studies in rice (Oryza sativa sp.) under extreme weather scenarios generally use constant temperatures to influence the crop responses without relation actual changes. These heat may have limited implications for future yields because elevated are not based on local temperature fluctuations. This study investigated night-time air pattern and assessed status reliability of available ...

The effects of temperature on real time changes in optical density (DeltaOD) of GAFCHROMIC EBT film were investigated. The spectral peak of maximum change in absorbance (lambdamax) was shown to downshift linearly when the temperature of the film was increased from 22 to 38 degrees C. The DeltaOD values were also shown to decrease linearly with temperature, and this decrease could not be attribu...

In many signal processing applications, an appropriate measure to compare two signals plays a fundamental role in both implementing the algorithm and evaluating its performance. Several techniques have been introduced in literature as similarity measures. However, the existing measures are often either impractical for some applications or they have unsatisfactory results in some other applicati...

A precise test of the theory of stellar evolution can be performed by measuring the average difference in energy between the neutrino line produced by 7Be electron capture in the solar interior and the corresponding neutrino line produced in a terrestrial laboratory. This energy shift is calculated to be 1.29 keV (to an accuracy of a few percent) for the dominant ground-state to ground-state tr...

background and objectives: work sampling is a useful technique to characterize how employees allocate their work time to various activities. given the value of nurses’ time for quality health care delivery, characterization of nursing time distribution may provide useful information for optimal use of nursing staff. the purpose of the present study was to explore time allocation by nurses using...

Prepregs of a mixture of the tetrafunctional epoxy tetraglycidyl 4.4-diaminodiphenyl methane (TGDDM) and the tetrafunctional amine 4.4'-diaminodiphenylsulfone (DDS) were characterized with temperature-modulated DSC (TMDSC) as well as dynamic mechanical analysis (DMA). The baseline shift of the glass transition was separated from the curing exotherm by using temperature-modulated and step scan D...
