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

Behind the curve: a comparison of historical sources for the Carnegie curve of the global atmospheric electric circuit [PDF]
History of Geo- and Space Sciences, 2020 The “Carnegie curve” describes the diurnal variation of the global atmospheric electric circuit. It was originally found from atmospheric electric potential gradient (PG) measurements made on the Carnegie, effectively a floating atmospheric electrical ...

Compensation Method for Diurnal Variation in Three-Component Magnetic Survey
Applied Sciences, 2020 Considering that diurnal variation interferes with three-component magnetic surveys, which inevitably affects survey accuracy, exploring an interference compensation method of high-precision is particularly desirable. In this paper, a compensation method

Tongue Strength of Older Adults Requiring Long-Term Care Varies throughout the Day
Geriatrics, 2023 Physical performance shows approximately 30% diurnal variation; however, diurnal variation in oral function remains unclear. This study aimed to determine the diurnal variation in oral and swallowing function in older adults requiring long-term care. The

Diurnal Variation in Root Respiration [PDF]
Plant Physiology, 1962 The existence of a diurnal fluctuation in root metabolism can be deduced from several studies. While studying root respiration, Harris (13) noted a diurnal variation in the rate of CO2 production by roots of tomatoes and certain deciduous fruit trees.

Diurnal variations in myocardial metabolism [PDF]
Cardiovascular Research, 2008 The heart is challenged by a plethora of extracellular stimuli over the course of a normal day, each of which distinctly influences myocardial contractile function. It is therefore not surprising that myocardial metabolism also oscillates in a time-of-day dependent manner.
