âThe savings are roughly 9 percent for the corridor and 17 percent for the classroom,â the study found. With this same scenario, switching from a 30 percent to a 45 percent light reflectance floor results in an energy saving of roughly 4 percent for corridors and 9 percent for classrooms.
The Axial Age is defined by Jaspers as occurring in the interval from about 800 to 200, but a closer analysis suggests the need to modify and break up this interval. However, the basic point is clear. But the Axial phenomenon is evanescent and begins to wane rapidly by 400.
Medical Definition of Maternal age. Maternal age: The age of the mother at the time of delivery. Advanced maternal age is usually defined as age 35 or more at delivery. Advanced maternal age predisposes to Down syndrome (trisomy 21). The risk of having a Down syndrome baby rises with maternal age. It essentially doubles from 1 in 725 at maternal age 32 to 1 in 365 at maternal age 35. And the risk continues to climb with the years and is 1 in 32 at maternal age 45.
