PMMA is a polymer that has a high impact strength‚ is scratch and shatter resistant‚ and is relatively lightweight1. Because PMMA can also be formed into a transparent thermoplastic and has a glass transitions temperature of 130oC‚ this polymer served as a glass substitute in its early uses1.

Animal experimentation is a big part of medical progress. Opponents of animal testing point out the amount of animals used and the different types of animals used but if you look at it‚ it’s all for a good reason. Animal experimenters don’t do this just to do it. It’s for a purpose. There are thousands upon thousands of medical situations that couldn’t have been done without animal experimenting. Animal suffering is pointed out but for the most part animals go without feeling any pain. Animal experimentation

This probably due to the lack of an extensive research to study and evaluate those treatments (Gauglitz et al.‚ 2011). There are a wide range of therapies that have been used in treating keloid and hypertrophic scars. Although most of the therapeutic options that we will cover work for both scars‚ we have to be very

However some research suggests that the RF energy is a low frequency energy that is incapable of causing detrimental effects to the cells in the body. Some studies do not demonstrate a strong causal relation between RF exposure from cell phones and negative
