Exposure to cigarette smoke is by far the most common causative factor for chronic obstructive pulmonary disease. Occupational exposure to fumes, chemicals, dusts and environmental pollution is also an important cause of chronic productive cough. Emphysema developing as a consequence of an occupational exposure is extremely rare. We describe the rare occurrence of severe emphysema in a non-smok...

Hydrodynamic performance of gas microbearings, fabricated with deep X-ray lithography and electroplating, will be presented in this article. Static performance in terms of load parameters and attitude angles was calculated using Molecular Gas Lubrication (MGL) theory. Threshold speed and allowable rotor mass were calculated to investigate safe operating conditions of the fabricated gas microbea...

A trivalent chromium electroplating process has been io use commercially in North America since its introduction in 1975. Based upon years of laboratory and in-plant experience and testing, many process performance characteristics and physical properties of deposits have been determined. This paper compares the performance of trivalent chromium with hexavalent chromium processes. Factors such a...

In this paper we present a method for preparation of technical drawings in the domain of electroplating lines. We treat the method as the combination of two tasks: configuration and document preparation. The proposed method combines the basic concepts of these domains: generic coding introduced in document preparation task and component oriented approach used in the configuration task. We show ...
