The Medical doctorate (abbreviated as M.D.) is equivalent to the Ph.D. degree. To earn an M.D. in a science specialty, one must have a master's degree (M.Sc.) (or two diplomas before the introduction of M.Sc. degree in Egypt) before applying. The M.D. degree involves courses in the field and defending a dissertation.
How long does the battery last? On average, the Canary Flex battery life is two to three months of normal use. Canary calls the Canary Flex lithium ion battery an âextended-life rechargeable battery.â It only draws battery power when unplugged, so if you leave it plugged in at all times, it will use the battery as a backup power source.
While it's unclear how common the problem is, some Fitbit Flex users have posted on forums and social media sites about experiencing issues with their Flex holding a charge after just a few months of use. (The Flex battery generally lasts five days between charges, according to the company.). For example, Karen Hamilton, a Fitbit user who said she received her tracker as a gift, posted on a Facebook thread in July that her two-month-old Flex was unable to hold a charge for an hour. If your Fitbit device does not hold a charge, Fitbit recommends the following: 1  Clean the charger contacts. 2  Try charging from a different USB port. 3  Try charging from a computer USB port instead of a USB hub.
