Systematic study of effect of cross-drafts and nozzle diameter on shield gas coverage
No full textA shield gas flow rate of 15–20 L min21 is typically specified in metal inert gas welding, but is often adjusted to as high as 36 L min21 by welders in practice. Not only is this overuse of shield gas wasteful, but uncontrolled high gas flows can lead to significant turbulence induced porosity in the final weld. There is therefore a need to understand and control the minimum shield gas flow rate used in practical welding where cross-drafts may affect the coverage. Very low gas coverage or no shielding leads to porosity and spatter development in the weld region. A systematic study is reported of the weld quality achieved for a range of shield gas flow rates, cross-draft speeds and nozzle diameters using optical visualisation and numerical modelling to determine the shield gas coverage. As a consequence of the study, the shield gas flow has been reduced to 12 L min21 in production welding, representing a significant process cost saving and reduced environmental impact with no compromise to the final weld quality

Did Blue Cross and Blue Shield Suffer from Adverse Selection? Evidence from the 1950s
No full textThis paper uses a unique data set from 1957 to examine whether or not Blue Cross and Blue Shield suffered from an adverse selection death spiral after for-profit commercial insurance companies entered the market for health insurance. Results suggest that moving to experience rating may have helped the Blues counteract adverse selection in the group health insurance market. Adverse selection posed a greater problem for the Blues in the market for individual health insurance, possibly because of differences in the way the Blues screened potential enrollees relative to commercial insurance companies.

Leonard Shield, Price, Utah, Carbon County oral history project, Nos. 22 and 23, April 14, 1983
No full textThe interview with Leonard Shield covers the subjects of his background, railroad transportation experiences, growing up in Hiawatha, the Castle Gate mine explosion, the 1928 Kennilworth explosion and rescue operations, experiences at Mohrland, coal mining experiences, Union activities, his father\u27s experiences as Utah State Mine Inspector, and mining at the Peacock and Milburn mine. The Carbon County oral history project (1972-1993) consists of oral histories from residents of Carbon County, Utah. While the main emphasis is on living in coal mine country, the interviews are verbal snapshots of rural Utah life from the earliest settlers to as recently as 1993
