Young Women's Misinformation Concerning IT Careers: Exchanging One Negative Image for Another

This research reports on the results of a study of 412 girls, ages sixteen through eighteen, in a major Midwestern United States city. The study, which also uncovered unexpected racial differences, found that, contrary to the preponderance of the research evidence, most high school girls say that they do not view those who choose IT careers as being geeks or loners. These results, which also co...

Another hazard of gold therapy?

A patient with seropositive rheumatoid developed a bullous eruption localised to the jewellery areas 12 hours after a test dose of sodium aurothiomalate (Myocrisin). Investigation showed that she was allergic to nickel rather than gold. Small quantities of nickel were found in the Myocrisin solution after a short contact with a metal needle, suggesting an explanation for the reaction.

Intracoronary thrombolytic treatment: another hazard.

A patient with acute anterior myocardial infarction was treated with intracoronary thrombolysis. At cardiac catheterisation the first contrast injection into the left coronary artery dislodged some of the thrombus occluding the left anterior descending coronary artery. The thrombus embolised into the circumflex artery where fortunately it fragmented without causing occlusion. The risk of detach...

Vortex rings of one fluid in another in free fall

Experiments in which vortex rings of one immiscible liquid are created in another from drops falling from rest under gravity are presented and interpreted. These rings are associated with circulations generated by viscosity and, unlike classical vortex rings which occur in miscible liquids at high Reynolds numbers, they can exist even at very low Reynolds numbers. Since the rings do not diffuse...
