Diurnal Cycles and Cannibalism in Planaria

Science, 1960
Dugesia tigrina attacks Cura foremani under certain circumstances. The length of fast prior to the attack and diurnal rhythms are involved in evoking such behavior.

“Humanizing” mouse environments: Humidity, diurnal cycles and thermoneutrality

Biochimie, 2023
Thermoneutral housing has been shown to promote more accurate and robust development of several pathologies in mice. Raising animal housing temperatures a few degrees may create a relatively straightforward opportunity to improve translatability of mouse models.

Diurnal potassium excretory cycles in the rat

American Journal of Physiology-Renal Physiology, 1986
Diurnal potassium cycles (DPC) were measured in unanesthetized undisturbed rats fed a liquid diet and maintained in a 12-h light-dark environment. A fourfold step increase in diet potassium content increased DPC amplitude without altering phase. After presentation of the high-potassium diet, the initial adaptive increase in excretion occurred within 1.

Diurnal Cycle of Refraction after Radial Keratotomy

Ophthalmology, 1987
A single patient was refracted 1000 times at all hours of the day in the year after bilateral radial keratotomy (RK). Preoperatively, there was practically no diurnal variation of refraction. Postoperatively, the refraction showed a myopic shift of several diopters from early morning to late evening. Transient hyperopia was superimposed on this diurnal

The diurnal cycle of tropical convection

Journal of Geophysical Research: Atmospheres, 1993
The diurnal cycle of tropical convection is investigated with global cloud imagery constructed from 11μm radiance measurements taken aboard six satellites. Four harmonics of the diurnal cycle are resolved in the cloud imagery with about 50 km horizontal resolution.

Modeling the atmospheric diurnal cycle

2020
Weather and climate influence life in many ways; varying climatic conditions can be associated with varying human cultures and on a day-to-day basis, the weather influences our plans and mood. As such, a proper prediction of the weather is of great importance. Ultimately, the weather is fueled by solar irradiation, which changes sharply over the course

Surface diurnal cycle over Venezuela

Meteorology and Atmospheric Physics, 1998
The surface thermodynamic diurnal cycle over Venezuela is compared with that over Kansas grassland and the Canadian boreal forest, illustrating the greater upward transport of water vapor out of the subcloud layer by shallow cumulus clouds in the tropics, which limits the daytime rise of θ E .

The martian diurnal water cycle

Advances in Space Research, 1999
Abstract Near-surface water (both in the regolith and atmosphere) represents a potentially important resource for the exploration of Mars. However, most analyses of these resources (cf. Mellon and Jakosky, 1993, and references therein) hearken back to the seminal discussion of Martian volatiles by Leighton and Murray (1966) which assumed a planetwide

Diurnal cycles of land surface temperatures

Advances in Space Research, 1998
Abstract Monthly mean diurnal cycles of temperatures over land, Ts, have been analyzed. Data include a 19-year climatology of station observations of ground and air temperatures, separately for all and clear skies (Tga, Tgc, Taa, Tac, respectively) over 75 sites in Russian, and a 7-year near-global climatology of satellite observations of surface ...

The Diurnal Cycle in the Tropics

Monthly Weather Review, 2001
A global archive of high-resolution (3-hourly, 0.58 latitude‐longitude grid) window (11‐12 mm) brightness temperature (Tb) data from multiple satellites is being developed by the European Union Cloud Archive User Service (CLAUS) project. It has been used to construct a climatology of the diurnal cycle in convection, cloudiness, and surface temperature ...
