People Who Suffer Depression And Anxiety After A Traumatic Brain Injury May Have Damaged White Matter. Jun 16, 2015 12:00 AM By Ed Cara @EdCara4. Researchers from the University at Pittsburgh Medical Center may have figured out why people suffer depression and anxiety after a concussion.
How to Read Speed Rating, Load Index & Service Descriptions. Using a P195/60R15 87S tire size as our example, the 87S at the end of the size represents the tire's service description. A service description identifies the tire's load index and speed rating.
Speed is expressed in kilometres per hour (km/h). Tip : When you see a speed limit sign, assume it means km/h, even if it does not say km/h. For example, if you see a sign that says 100, assume it means 100 km/h (60 mph).
