QuickBird satellite imagery was evaluated for differentiating among rangeland cover types on the Welder Wildlife Refuge in south Texas. The satellite imagery had a spatial resolution of 2.8 m and contained 11-bit data. Four subsets of the satellite image were extracted and used as study sites. Field spectral measurements made among the dominant vegetation types showed significant differences in...

BACKGROUND Metal fume fever (MFF) is a well-known complication of zinc oxide fume inhalation. Prompt recognition of this condition is essential for the proper medical management of this self-limited disease. AIM To present a unique and unusual case of MFF. RESULTS Our patient is a 25-year-old male welder who had MFF and presented with aseptic meningitis with pericarditis, pleuritis and pneu...

Welding fume is generated during welding activities and a known cancer-causing hazard for those working in the industry. Worker exposure has been shown to regularly exceed applicable workplace standard, control measures are required reduce worker exposure. The aim of this study compare effectiveness prevent workers. To achieve aim, three common (local exhaust ventilation (LEV), powered air puri...

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...

Abstract There are several possibilities for establishing a cohesion joint between dissimilar metals. In the case of thin sheets, ultrasonic welding process is suitable. This can establish rapidly, with low heat input sheets. The authors have tried to determine optimal parameters copper and austenite stainless steel joining by using an experimental method joining. Suitable results were obtained...
