The infrasound frequency band has many uses in Atmospheric Physics and geophysics. Earthquakes, typhoons, such as the "UTA" in the South China Sea a few days ago, durian and a series of other typhoons, all produce infrasound. From thousands of kilometers away, the signal can be received b...
Introduction: Over the past decade, low-intensity extracorporeal shockwave therapy (Li-ESWT) has emerged as a treatment modality for erectile dysfunction (ED). To better appreciate the differences between the various devices for the treatment of ED, it is imperative for physicians to understand the...

PhysicsThis chapter deals with the physical and mathematical aspects of sound when the disturbances are, in some sense, small. Acoustics is usually concerned with small-amplitude phenomena, and consequently alinear description is usually applicable. Disturbances are governed by the properties of the ...

The reason why an electromechanical alternator outputs sine-wave AC is due to the physics of its operation. The voltage produced by the stationary coils by the motion of the rotating magnet is proportional to the rate at which the magnetic flux is changing perpendicular to the coils (Faraday’...
Basic cognitive research can help to explain our response to wine, and the myriad factors that affect it. Wine is a complex, culture-laden, multisensory stimulus, and our perception/experience of its properties is influenced by everything from the packag
