Using microwave brightness temperature diurnal cycle to improve emissivity retrievals over land" (2012). a b s t r a c t a r t i c l e i n f o Keywords: Emissivity Brightness temperature Diurnal cycle Land Passive microwave Effective temperature Vegetation Soil moisture To retrieve microwave land emissivity, infrared surface skin temperatures have been used as surface physical temperature since...
Abstract The present work deals with the study of first three harmonics of low amplitude anisotropic wave trains of cosmic ray intensity over the period 1991-1994 for Deep River neutron monitoring station. It is observed that the diurnal time of maximum remains in the co-rotational direction; whereas, the time of maximum for both diurnal and semi-diurnal anisotropy has significantly shifted tow...
In mammals, most physiological, biochemical, and behavioral processes show a circadian rhythm. In the present study, we examined the diurnal rhythm of the H+-peptide cotransporter (PEPT1), which transports small peptides and peptide-like drugs in the small intestine and kidney, using rats maintained in a 12-h photoperiod with free access to chow. The transport of [14C]glycylsarcosine (Gly-Sar),...
AIMS To quantify the relationship between the timing of gastroesophageal reflux disease (GERD) symptoms and the burden of illness. PATIENTS & METHODS Data from the 2010 National Health and Wellness Survey were used. Regression analyses compared non-GERD controls with GERD patients with diurnal symptoms, nocturnal symptoms, and both diurnal and nocturnal symptoms, controlling for potential con...
PURPOSE To evaluates the role of measuring intraocular pressure (IOP) outside office-hour in primary adult onset glaucoma. METHODS This retrospective study included 100 cases of primary adult onset glaucoma. IOP readings obtained with Goldmann applanation tonometry between 7 am and 10 pm were compared to office-hour readings. RESULTS One hundred patients were enrolled (mean age: 58.64 ± 10....
[1] Using 22 months of Sunphotometer Aerosol Optical Thickness (AOT) data collected near the Taklamakan and Gobi dust source regions (Dunhuang, 40.09 N, 94.41 E) in China; we examine the diurnal and seasonal change of dust aerosol properties. Most dust events are during the spring through early summer months with a season-invariant diurnal change of more than ±10% for AOTand ±30% for Angström e...
All domains of life feature diverse molecular clock machineries that synchronize physiological processes to diurnal environmental fluctuations. However, no mechanisms are known to cross-regulate prokaryotic and eukaryotic circadian rhythms in multikingdom ecosystems. Here, we show that the intestinal microbiota, in both mice and humans, exhibits diurnal oscillations that are influenced by feedi...
Out of a total of 2272 diurnal curves (DC) of intraocular pressure (IOP) obtained from 1178 patients 690 first curves of the right eye of all patients were analysed. For each DC there were 4-6 IOP readings taken between 8 am and 6.30 pm of the same day. The patients' diagnosis, age, sex, type of IOP lowering medication, diabetes, and the calendar month of the year were recorded. In 40% of cases...
To determine the influence of circadian rhythmicity and sleep on the 24-h leptin diurnal variations, plasma leptin levels were measured at 10-min intervals over 24 h in seven normal subjects, once during nocturnal sleep, and once after an 8-h shift of sleep. The subjects were submitted to constant conditions (continuous enteral nutrition and bed rest in controlled chambers). Body temperature an...
