Power Electronics: Devices, Drivers, Applications and Passive Components

Only by understanding both semiconductor device theory and high-power application can the designer be sure of selecting the correct power device for a given application. This book covers both the switches themselves and the circuitry required to make them work effectively. In this revised and updated version the author has added an entire new section on passive components - capacitors, soft magnetic materials, and resistors. 

Practical Guide for Magnetic and Spiritual Healing

To heal through passes is not a modern concept; it is as old as Man himself. The Spiritist definition of health is characterized by the degree of Spirit's commitment to the natural laws. Jesus taught us to love our neighbor and the pass is one of the many ways we can practise this.

 

Handbook of Magnetism and Advanced Magnetic Materials

Magnetic materials are used ubiquitously in the modern world, in fields as diverse as, for example, electrical energy transport, high-power electro-motors and generators, telecommunication systems, navigation equipment, aviation and space operations, micromechanical automation, medicine, magnetocaloric refrigeration, computer science, high density recording, non-destructive testing of materials, and in many household applications. Research in many of these areas continues apace.

Although rectal and perianal complaints are among the most common seen by primary care physicians, surgeons, and gastroenterologists, the wide variety of disorders associated with these complaints are, in general, poorly understood. Additionally, a variety of newer diagnostic techniques, such as endoscopic ultrasound, mannometry, and magnetic resonance imaging, are now being employed for the evaluation of these disorders.

Product Description:
Progress in medicine has often been initiated by discoveries and results from various disciplines of natural science. One of the most famous examples is the X-ray. In this case, its importance with respect to medical applications was immediately recognized and its development was propelled by fruitful cooperation between physicians and physicists. In other cases, e.g. that of NMR, the period between discovery and subsequent application in medicine was longer. Sometimes, a method has become established in clinical practice only after having passed through a long period of in vitro investigations and preclinical trials, while there are also applications that could only be seriously developed once crucial parts had been invented.
