Diurnal variability of hydrological variables in urban areas

Urban Climate, 2020
Abstract Urbanization modifies the hydrologic response of a catchment significantly. An understanding of historical patterns and changes in trends of hydrological variables in cities is important to design, maintain and operate the urban infrastructure. The historical trend analysis of various climate variables including temperature and precipitation,

Diurnal variability in cranial dystonia

Movement Disorders, 1990
AbstractEleven patients with cranial dystonia were investigated for diurnal variations in disability by means of video recordings. Disability increased significantly from morning to evening. The increase was not related to changes in vigilance levels assessed by dynamic electroencephalogram.

Diurnal Variability of Peak Expiratory Flow

Journal of Asthma, 2002
Diurnal variation in peak expiratory flow (PEFvar) has been suggested as a surrogate for bronchial hyperreactivity, and may be a useful tool in the management of bronchial asthma. Several indices have been postulated to measure PEFvar; however, the number of daily measurements and the timing of recordings are not clearly established.

Diurnal Variability of Orofacial Dyskinetic Movements

Pharmacopsychiatry, 1999
Instrumental methods to measure tardive dyskinesia (TD) have been introduced in the last few years to try to eliminate the differences in inter-rater reliability. After eliminating variations attributed to the use of different raters, it is clear that TD frequently shows fluctuations in severity contributing to a low test-retest reliability.

Diurnal Heart Rate Variability Fluctuations in Normal Volunteers [PDF]

Journal of Diabetes Science and Technology, 2014
Although an imbalance in cardiac autonomic function is a known cause of cardiovascular diseases such as myocardial infarction and stroke,1 methods for monitoring heart rate variability (HRV) that reflect autonomic nervous system activity2-3 in real life have not been devised.

Diurnal variability of thermospheric N and NO

Planetary and Space Science, 1977
Abstract A model for diurnal variations of neutral and ionic nitrogen compounds in the thermosphere is reconstructed on the basis of a new photochemical aspect on N(2D), together with new observations of the NO density. The NO density so far measured must be reduced by a factor 2, due to a revision of the fluorescence coefficient for the NO γ-band ...

Intraseasonal Variability of the Philippines Diurnal Cycle

2022
<p>The diurnal cycle in tropical islands is critical for water supplies and agriculture, and potentially has important feedbacks onto longer timescale tropical disturbances. However, the conditions that regulate the diurnal cycle of rainfall on such islands remain poorly understood.  Here, we use observations and a cloud ...

The Diurnal Variability of Florida Rainfall

Monthly Weather Review, 1979
Abstract The diurnal variation of precipitation over the Florida peninsula is investigated on the basis of harmonic analysis of hourly rainfall data. Hourly data on the frequency of three categories of precipitation events for around 70 stations in Florida were processed, generating statistics of amplitude and phase of the diurnal precipitation cycle ...

Individual Variability in the Diurnal Intraocular Pressure Curve

Ophthalmology, 1993
Reduction of intraocular pressure (IOP) is a primary goal of most glaucoma treatments. However, because the IOP varies during the day, single measurements performed in an ophthalmologist's office do not necessarily provide information on the peak level and fluctuation of the IOP.Home tonometry was performed to gain more information on the nature of the

Diurnal Variability of Auditory Threshold

Acta Oto-Laryngologica, 1964
The absolute threshold for hearing was measured at 7 a.m., noon, 5 p.m., and midnight for 4 days on 6 listeners. No diurnal periodicity appeared, indicating that time of day per se does not constitute a significant source of variance in studies using absolute sensitivity as the dependent variable.
