[Pulmonary siderosis in an arc welder].
An arc welder of 32 years of age is presented with a random finding of miliar reticulonodular shadows in the plain film of the thorax. Subjectively and objectively the patient appears healthy. The presence of a pneumoconiosis is confirmed by biopsy. Differential diagnosis had to consider sarcoidosis and pulmonary siderosis in view of the known professional anamnesis. This case report underlines...
متن کاملMacular degeneration in an arc welder.
A male welder who had been working in an industrial machine plant for more than 20 years experienced acute intense pain in his left eye with continuous lacrimation while performing arc welding in 1997. Later in 1997, at the age of 39 yr, macular edema was found in his left eye. He was diagnosed with macular degeneration (MD) of the left eye in 2002, and with right eye MD in 2004. Radiation in t...
متن کاملAmount and distribution of fume contaminants in the lungs of an arc welder post mortem.
This study describes various post-mortem examinations of the lungs of a shipyard arc welder. These investigations comprised morphological methods, including gross pathology and radiography, histological and ultrastructural examinations, chemical analysis of lung tissue, and sensitive magnetic measurements, which can now be used to detect magnetic contaminants, such as welding fume, in human tis...
متن کاملVoltage Stability Limit Enhancement using Thyristor Controlled Series Capacitor (TCSC)
Flexible Alternating Current Transmission System (FACTS) devices can regulate the active and reactive power control as well as adaptive to voltage magnitude control simultaneously, because of their flexibility and fast control characteristics. Placement of these devices in suitable location can lead to control in line flow and maintain bus voltages in desired level and so improve voltage stabil...
متن کاملImproving Pacific Intertie Stability Using Slatt Thyristor Controlled Series Compensation
This paper discusses control design issues for the existing thyristor controlled series compensation (TCSC) device at Slatt substation on the Slatt–Buckley 500-kV transmission line owned by BPA. The controls were developed at Washington State University (WSU) in a project funded by Bonneville Power Administration (BPA). The project has been carried out in close collaboration between the WSU tea...
