Acromioclavicular (AC) joint injury occurs on the top part of the shoulder where the collarbone attaches to the front side of the shoulder. The injury can be caused in different ways such as repetitive use of the shoulder or a fall. AC injuries are common to more men than women aged below 35 years. This is majorly because most of these individuals are much likely to participate in high-risk activities such as sports‚ or even work-related tasks like roofing. AC joint can be handled effectively by

Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food
