recent studies demonstrate that aluminide coatings are beneficial to wear and erosion resistance and also that oxygen-active elements such as yttrium can remarkably improve this resistance. in this research, the micro-hardness of the aluminide coatings with and without yttrium on 1045 steel was investigated using a micro-mechanical probe. wear of the samples was measured using a pin-on-disk tri...

We present multiwavelength imaging observations of PKS 1045−188, 8C 1849+670, and PKS 2216−038, three radio-loud active galactic nuclei from the MOJAVE-Chandra Sample that straddle the Fanaroff-Riley (FR) boundary between lowand high-power jets. These hybrid sources provide an excellent opportunity to study jet emission mechanisms and the influence of the external environment. We used archival ...

Using a large data set, the authors find that smokers select riskier jobs, but receive less hazard pay than do nonsmokers. Based on estimates using the BLS rate of lost workdays, nonsmokers have an implicit value per injury of $39,017 as compared to $20,469 for smokers. Smokers are injured more often controlling for the job’s objective risk and are paid less after such injuries. This evidence i...
