    In this paper we calculate the contact force needed to fracture the surface of a FIFA regulated football. We also determine the speed at which the leg kicking the ball must be travelling in order to generate this force. The force required is 990409 N; to generate this force the leg would have to travelling at over 400mph

    Complete Vaporisation of a Human Body

    From the previous paper, we were able to determine, hypothetically, the approximate amount of energy required to completely vaporise a human skeleton. In this paper, we focused on vaporising the whole water constituent of the body and the remaining tissues of a human body by finding the total dissociation energy for each of this constituent. For simplification, we used dried pork to represent the remaining tissues of the body. Finally, we calculated the combined amount of energy required to completely vaporise a human body to be 2.99G

    Preventing the Incidence of Fusarium keratitis Infection in Contact Lens Wearers

    Fusarium keratitis is a serious eye infection of the cornea that has recently been prevalent with contact lens wearers. In 2006, an outbreak of the infection was found to be mostly due to a certain brand of contact lens solution, ReNu with MoistureLoc®, which was withdrawn from the market. However, a very recent incidence of the infection that lead to blindness in the patient, has led to a necessity on educating contact wearers on the importance of proper handling of their contact lens. We highlighted the importance of not reusing contact lens solution due to the depreciation in its antimicrobial properties after one use. It was also recommended those contact lenses are stored in a barrel container which suspends the contact lens in its solutio
