The Second Heart Sound

The second heart sound (S2) is a short burst of auditory vibrations of varying intensity, frequency, quality, and duration. It has two audible components, the aortic closure sound (A2) and the pulmonic closure sound (P2), which are normally split on inspiration and virtually single on expiration. S2 is produced in part by hemodynamic events …

Light intensity effects on photocatalytic water splitting …

 — The effect of light intensity on photocatalytic water splitting was examined experimentally. • Degussa P25 TiO 2 films and a Xenon arc lamp were used to illuminate a cell at intensities up to 52 suns.. A sub-linear relationship where photocurrent was proportional to intensity with an exponential value of 0.627 was found.. This sub-linear …

5.3: Zero-field interaction

 — In the high-temperature approximation, the integral intensity in the absorption spectrum is the same for all transitions. Hence, broader transitions make a smaller contribution to the amplitude in the absorption spectrum and in its first derivative that is acquired by CW EPR.

On the Relation between the Open‐Circuit

 — Here, intensity-dependent measurements of the quasi-Fermi level splitting (QFLS) and of the V OC on the very same devices, including pin-type PSCs with efficiencies above 20%, ... is able to prevent the V OC saturation until relatively high intensity and to nullify the QFLS-V OC mismatch.

HIT MASS: 4 & 5 Day High Intensity Training Splits

 — Last month, we shared with you a beginner version of High Intensity Training.. HIT is a style of training that involves a single work set to ultimate failure and places emphasis on both the preparation for that work set as well as the recovery after training.. If you tried it, we hope you saw gains as a result.

Cardiac Auscultation

Rubs are high-pitched, scratchy sounds often with 2 or 3 separate components, which may vary according to body position; during tachycardia, the sound may be almost continuous.. The clinician focuses attention sequentially on each phase of the cardiac cycle, noting each heart sound and murmur. Intensity, pitch, duration, and timing of the sounds and the …
