Extreme temperatures threaten desert songbirds with death by dehydration
Extreme temperatures threaten desert songbirds death by dehydration
2017/3/13
According to NASA, 2016 was the hottest year on historical record. Globally, the increase amounted to nearly 1.8 degrees Fahrenheit. And while that might not sound like much of an increase, it could m...
Noninvasive assessment of extracellular and intracellular dehydration in healthy humans using the resistance-reactance–score graph method
volume depletion hydration assessment BIVA hypohydration hypovolemia
