Abstract. Since the introduction of the ultrasonic aspirator developed and adapted for neurosurgery by the Cooper Scientific Corporation over the past decade, the instrumentation has gained wide acceptance in the removal of certain central nervous system tumors.
The majority â 70 percent â of Americans explained the reason they did not regret opening a store credit card during the holiday shopping season was because they received a large discount on their original purchase. Although shoppers may feel bullied, they are also sympathetic for the position the store clerk is in.
America continues to get heavier. An analysis of data collected from 2007 to 2012 has found that 71 percent of Americans are obese or overweight. The picture is slightly worse for men, three-fourths of whom are overweight or obese. About 67 percent of women fall into one of those two categories. In all, nearly 35 percent of Americans are overweight, meaning that they have a body mass index between 25 and 29.9. This metric is a generally reliable way of estimating body fat percentage, though it can overestimate fat in athletes and those with a particularly muscular build.
