Metals Recovery From Acid Mine Drainage Using Pervious Concrete
Pervious concrete has grown in popularity as analternative infrastructure medium to enhance thequality of surface water in developed geographicalareas. Previous studies have shown that perviousconcrete structures and the subgrade layer thatsupports them are effective at significantly reducingthe concentrations of common pollutants such as soap,motor oil, brake fluid, brake dust, and roof shingleparticles from rain water and snow melt. Studiesthus far have shown enough promise to encouragegrowing use of pervious concrete in infrastructurecategories such as storm channels, sidewalks andparking lots. This paper examines the use ofpervious concrete to remove metals and neutralize pHfrom a synthetic solution simulating acid minedrainage (AMD). In addition, destructive testing ofcores taken from pre-filtration and post filtrationfilters were used to evaluate the potential lifespanof a pervious concrete filter when exposed to theprolonged flow of polluted water.The dimensions of the filter allow for ease ofhandling by manual labor or the use of machinery thatcan be transported by standard off-road vehicles.- Shop: buecher

My Sweet Angel: The True Story of Lacey Spears, the Seemingly Perfect Mother Who Murdered Her Son in Cold Blood , Hörbuch, Digital, ungekürzt, 710min
Lacey Spears made international headlines in January 2015, when she was charged with the "depraved mind" murder of her five-year-old son, Garnett. Prosecutors alleged that the 27-year-old mother had poisoned him with high concentrations of salt through his stomach tube. To the outside world, Lacey had seemed like the perfect mother, regularly posting dramatic updates on her son's harrowing medical problems. But in reality, Lacey was a textbook case of Munchausen Syndrome by Proxy. From the time he was an infant, she deliberately made Garnett sick to elicit sympathy from medical professionals, as well as her hundreds of followers on Facebook and other social media. When a Westchester County jury found her guilty of killing Garnett in April 2015, she was sentenced to 20 years to life in prison. Using Lacey's own never-before-seen Facebook, Twitter, and blog posts, an exclusive prison interview with Lacey herself, as well as interviews with her family and the three police investigators who broke the case, My Sweet Angel gives the definitive account of this extraordinary case that shocked the world. ungekürzt.
