Physical Conditions for Ferromagnetic Resonance [PDF]

Physical Review, 1956
All but one of the multiple ferromagnetic resonances observed by White and Solt in a sphere are shown to correspond to modes in which the oscillating part of the magnetization is independent of r (the only case ordinarily considered) or varies linearly with r in the sample.

“The Physical Condition of the Planets” [PDF]

Nature, 1941
I HAD not meant to express any special views about critical temperature. It is true that the atmospheres of Jupiter and Saturn are above the critical temperatures of some substances, but I imagine critical temperatures become completely unimportant when the pressure is 10,000 or more times the critical pressure; the a/v2 of Van der Waals becomes ...

Exploring the Impact of Training Methods on Repeated Sprints in Hypoxia Training Effects

Oxygen, 2023
Background: Emerging evidence suggests that the outcomes of hypoxia training may be influenced by various factors, contingent upon the chosen method, such as chamber, tent, or mask. This study aimed to examine how different training methods influence the

The Effect of Exercise on the Skin Content of the Reduced Form of NAD and Its Response to Transient Ischemia and Reperfusion in Highly Trained Athletes

Frontiers in Physiology, 2019
Reduced nicotinamide adenine dinucleotide (NADH) is synthesized in the cellular nucleus, cytoplasm and mitochondria but oxidized into NAD+ almost exclusively in mitochondria.

NSAID use as a shared decision-making variable in musculoskeletal rehabilitation and strength and conditioning: a perspective

Frontiers in Sports and Active Living
Pain relief is often considered a key indicator of musculoskeletal rehabilitation and load progression in physical training. However, nonsteroidal anti-inflammatory drugs (NSAIDs) can alter pain perception and symptom expression, posing new interpretive ...

Explicit and Implicit Processes in Human Aversive Conditioning [PDF]

, 2006
The ability to adapt to a changing environment is central to an organism’s success. The process of associating two stimuli (as in associative conditioning) requires very little in the way of neural machinery.
