Influence of radiation diurnal variation on the rapid intensification process of super Typhoon Rammasun (1409) in the South China Sea

open access: yesFrontiers in Earth Science, 2022
In this study, a sensitivity experiment based on a numerical model is conducted to study the influence of the diurnal variation of radiation on the rapid intensification process of Super Typhoon Rammasun (1409) in the South China Sea.

Relations between depressed mood and vocal parameters before, during and after sleep deprivation: a circadian rhythm study [PDF]

open access: yes, 1990
The mechanism underlying improvement after total sleep deprivation (TSD) was studied in 14 major depressed patients. The suggestions that (1) circadian processes and/or (2) dimensions of arousal may play a role in the response to TSD were investigated ...

Diurnal and Semi diurnal Atmospheric Variations [PDF]

open access: yesNature, 1909
I HAVE read the remarks of Prof. Horace Lamb in NATURE, November 5, 1908, p. 24, and November 12, 1908, p. 47, where, although mentioning difficulties, he apparently accepts the suggestions of Kelvin, Margules, and Hann that the semi-diurnal wave of pressure can be explained by the fact that “the daily variation of temperature is not harmonic, and when

Diurnal variation of tropospheric temperature at a tropical station [PDF]

open access: yesAnnales Geophysicae, 2001
The vertical velocity in the troposphere-lower stratosphere region measured using MST radar has been utilized to evaluate the temperature profile in the region. The diurnal variation of the tropospheric temperature on one day in August 1998 at the

Observational Characterization of the Downward Atmospheric Longwave Radiation at the Surface in the City of São Paulo [PDF]

open access: yes, 2010
This work describes the seasonal and diurnal variations of downward longwave atmospheric irradiance (LW) at the surface in São Paulo, Brazil, using 5-min-averaged values of LW, air temperature, relative humidity, and solar radiation observed continuously

Pilot Observational Study to Detect Diurnal Variation and Misalignment in Heart Rate Among Critically Ill Patients

open access: yesFrontiers in Neurology, 2020
Circadian disruption is common in critically ill patients admitted to the intensive care unit (ICU). Understanding and treating circadian disruption in critical illness has significant potential to improve critical illness outcomes through improved ...

Diurnal variation of magnesium and the mineral metabolism in patients with chronic kidney disease

open access: yesBone Reports, 2021
Increasing levels of magnesium in blood are associated with reduced risk of cardiovascular disease in chronic kidney disease (CKD). Magnesium supplementation may reduce the progression of vascular calcification in CKD.

Rabbit Diurnal Ocular Tension Variations

open access: yesOphthalmic Research, 1992
Ocular tension recorded by pneumatonography was estimated at 4-hour intervals during six consecutive 24-hour periods in 8 New Zealand rabbits. The animals had been acclimatized for more than 8 weeks to artificial light from 08.00 to 20.00 h and dark for the other 12 h.
