THe physics of the ear - Essay Example The ear also plays a role in maintaining physical stability and balance of the body. The size of the outer ear differs considerably among mammals—from the large floppy ears of the hare to the smaller ones for humans—though there is not much difference in its internal functioning across species. The size of the ear canal is determined by the skin, cartilage and bone formation at this location. Since there is no growth of cartilage in adulthood, the size of the ear canal remains unchanged. However, the outer ear grows in size through adulthood. Ferrario VF. Sforza C. et al., (19(4):226-33, 1999.) calculated the length of the left exterior ear from apex to the lowest part with a transparent ruler; the result (in mms) as well as the patients age, were noted. The results established that as humans grew older the outer ear correspondingly increased in size. The outer ear (pinna or auricle) is the part visible to us. Its main function is to collect sound waves and filter them; so the larger it is, it collects more sound waves and focuses them in the right direction. However, this part is not vital to hearing. Besides, the pinna plays no role in the ear’s function of providing the sense of balance. The outer ear also consists of the ear canal, where wax is produced. Earwax protects the canal by means of the chemicals it contains that keep infections at bay, and also by acting as a barrier to collect dirt, which keeps the ear canal clean. (3 D Ear-Website) The middle ear receives sound waves that move through the ear canal to reach it. The middle ear converts sound waves into vibrations delivered to the inner ear. It does this through the eardrum (tympanum) which is a thin piece of skin stretched tight. The eardrum separates the outer ear from the middle ear and the ossicles, which are the three smallest and most delicately crafted bones in the body. The ossicles consist of the malleus (hammer), which is attached to the eardrum, the incus

Property Law - Essay Example The law of England and Wales permits a person to transfer his interest in property to others after fulfilment of certain conditions in accordance with law. It happens if a person dies intestate, bankrupt, or the property taken in execution of a court judgment for auction to generate the proceeds towards appropriation of liabilities (Clarke & Kohler 129). Donation ‘mortis causa’ in conventional terms is considered as a gift to someone in anticipation of the death of its maker. The transfer of property is conditional or in other words, rests with the recipient immediately subject to the condition that the will giver’s death occurs shortly (Harpum, et al 72). c) The cited gentlemen landed in the jungles of Borneo. They passed the jungle to celebrate the birthday of John in shack. During the stay at night, they heard horrible noises outside their house, which scared John. They were in fear of being attacked that would cause their death. Therefore, John handed over a bunch of keys of his house to Tim, car and a Cheque to Tim. f) Ben, the ultimate beneficiary, knew nothing about what was going on. Tim and the rest of the team members on their way to hospital in an ambulance for the treatment of John met with an accident wherein Tim was killed. b) The second deficiency is that John only handed over the keys of his house, car and not transferred it in the name of John.
