The influence of the local terrestrial environment on nocturnal atmospheric CO2 measurements at a 329-m television transmitter tower (and a component of a CO2 monitoring network) was estimated with a tracer release experiment and a subsequent simulation of the releases. This was done to characterize the vertical transport of emissions from the surface to the uppermost tower level and how it is ...

Eight male subjects in each of three age groups (21-26, 40-45, 60-72 years) slept in pairs in the CAMI sonic boom simulation facility for 21 consecutive nights. The first five nights were used to acclimate the subjects (nights 1 and 2) and to obtain Baseline data (nights 3-5); the 12 subsequent nights (Boom) involved the hourly presentation of simulated sonic booms at an overpressure level of 1...

In a single-blind study six male patients (mean age 39.5 years) with moderate insomnia were treated with placebo for three nights, 100 mg indole-3-pyruvic acid (IPA) for three nights, 200 mg IPA for three nights, 100 mg IPA for two nights and placebo for two nights. Polygraphic recordings were made and total sleep time, sleep efficiency, sleep latency, slow wave sleep latency, rapid eye movemen...

Extreme climate events undoubtedly have essential impacts on terrestrial ecosystems, but the spatiotemporal patterns of extreme at regional scales are unclear. In this study, based observations and 14 CMIP6 global models, we analyzed changes in temperature mainland China scale different basin historical future periods, their relative importance for mean (Tmean). The results show that period, co...

The hypothesis that supplemental oxygen could improve the quality of sleep was tested in 23 consecutive patients (14 male, nine female; age 42-74 years) with chronic obstructive lung disease (mean (SD) FEV1 0.81 (0.32) litre, FEV1/FVC 37% (12%). Patients breathed compressed air or supplemental oxygen via nasal cannulas on consecutive nights in a randomised, double blind, crossover trial. Qualit...
