Recent college graduates might be a bit too confident about their workforce skills, a survey of students and hiring managers indicates. However, students in science, technology, engineering and mathematics (STEM) seem much better prepared to embark upon their careers.
Lean manufacturing tends to be associated with large-scale, mass-production manufacturing. But can smaller-scale job shops benefit from such process-improvement programs as well? Read more
As the national debate on hydraulic fracturing continues, a growing number of published studies point to potential dangers linked to the process. Among them is a paper written by two Duke University professors who report high levels of radioactivity in river water near a fracking site in western Pennsylvania.
Professors Robert Jackson and Avner Vengosh write in Environmental Science & Technology journal that they found highly elevated levels of radioactivity, salts, and metals in river water and sediments at the site where treated water from oil and gas operations are discharged.
“Radium levels were about 200 times greater in sediment samples collected where the Josephine Brine Treatment Facility discharges its treated wastewater into Blacklick Creek than in sediment samples collected just upstream of the plant,” Vengosh said. “We expected to see some radioactive material, but nowhere near that much.” Read more
