The magnetic properties of the nuclei of atoms can be used to yield chemical information. The nuclear magnetic resonance phenomenon is the basis of Magnetic Resonance Imaging, a technique extensively used in the medical radiology field.
Power Factor Correction can be performed by passive or active circuits. The advances in semiconductor technology and the low price of control integrated circuits have made the use of active solutions for PFC more appropriate for a wide range of applications.
The correct understanding of the thermodynamic properties of the nitrogen is essential for its safe use and the development of applications. This article presents some basic concepts on thermodynamics and applies them to the calculations of the properties of this gas.
Time Delay Relays are able to provide simple and reliable control. Solid State Time Delay Relays are more versatile and reliable than the mechanical models. This article explains some aspects of Solid State Relays (SSR) and their different types.
Reports on the presence of magnetic anomalies as well as an inter-dimensional portal in the Gulf of Aden are widely available on the Internet. This article explains the origin of those magnetic anomalies and covers some other causes of the great interest in the region.
Large industries and electrical utilities are very concerned about the presence of nonlinear loads in their electrical power systems. This article describes the causes of harmonics and their effects, as well as the means to improve power quality and to protect the equipment.
