Estimation of paracetamol in urine to assess the diurnal variation
The aim of the present study was to evaluate the diurnal variation of the pharmacokinetics of paracetamol by estimating the urinary free paracetamol level after single oral administration of paracetamol (500 mg) tablet to 24 healthy male volunteers ...

Photometric Studies of Auroral Luminosity and its Connection with Some Atmosphere Ionization Phenomena [PDF]
The auroral radiation, 3914 AO, received from the entire sky on a horizontal diffusing plate was monitored continuously during the nights of 1955-56 and 1956-57. The 1955-56 data and part of the 1956-57 data were used to obtain a diurnal curve for the

Reverse‐bias stability in monolithic perovskite/silicon tandem solar cells requires a silicon–current‐limited regime. When the perovskite current exceeds the silicon current, the reverse voltage is mainly borne by the silicon cell, reducing perovskite stress.

Magnetic fluctuation and cosmic ray diurnal variations [PDF]
A unified theory of cosmic ray diurnal variations has been proposed in which the first 3 harmonics of the cosmic ray daily variation all results from a single anisotropy produced by the combined effects of adiabatic focusing and anisotropic pitch angle ...

Consumer diversity drives stronger predation in tropical marine communities
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Rapid Fluctuations in Earth-Currents at College [PDF]
An unusual type of earth-current variation is regularly observed in the College records. The phenomena consist of more or less regular fluctuations with range from a few mv/km to more than 1000 mv/km, and periods ranging upwards from 6 seconds.

Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...

Modelling the effects of diurnal temperature variation on malaria infection dynamics in mosquitoes
Mosquito infection experiments that characterise how sporogony changes with temperature are increasingly being used to parameterise malaria transmission models.

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Earthworms, as ‘ecosystem engineers', play a crucial role in regulating ecosystem functions and shaping community structures. Due to climate change, earthworms face severe survival pressures and extinction risks. However, whether conservation efforts targeting aboveground biodiversity can cover the long‐neglected earthworm diversity remains unknown. To
