High voltage dry-type air-core shunt reactors
Dry-type air-core shunt reactors are now being used more frequently on high voltage power transmission systems to limit overvoltages. Recently, high voltage dry-type air-core shunt reactors have been designed, manufactured and installed directly connected to the transmission systems at voltages up to and including 345 kV. Applications at 500 kV are presently being considered. These ratings requ...
متن کاملVibroacoustic Therapy:
Vibroacoustic therapy is a recently recognized technology that uses sound in the audible range to produce mechanical vibrations that are applied directly to the body. The technology uses speakers or transducers placed within mats, mattresses, chairs, recliners, tables, or soft furniture to provide a physiologic and auditory experience. Benefits include pain management, anxiety relief, symptom r...
متن کاملIntegral Design Methodology of Photocatalytic Reactors for Air Pollution Remediation.
An integral reactor design methodology was developed to address the optimal design of photocatalytic wall reactors to be used in air pollution control. For a target pollutant to be eliminated from an air stream, the proposed methodology is initiated with a mechanistic derived reaction rate. The determination of intrinsic kinetic parameters is associated with the use of a simple geometry laborat...
متن کاملMesophilic and thermophilic biotreatment of BTEX-polluted air in reactors.
This study compares the removal of a mixture of benzene, toluene, ethylbenzene, and all three xylene isomers (BTEX) in mesophilic and thermophilic (50 degrees C) bioreactors. In the mesophilic reactor fungi became dominant after long-term operation, while bacteria dominated in the thermophilic unit. Microbial acclimation was achieved by exposing the biofilters to initial BTEX loads of 2-15 g m(...
متن کاملEchocardiography in Vibroacoustic Disease
Introduction. In 1980, research into the effects of low frequency noise (LFN, <500 Hz, including infrasound) -induced pathology began to be studied among a group of aircraft technicians. Vibroacoustic disease (VAD) has since been defined as the whole-body pathology caused by excessive exposure to LFN. In 1987, the first autopsy of a VAD patient was performed. Among the plethora of findings that...
