...The paper by Aoba and Fejerskov written in 2002 talks about a hypothesized mechanism being a dose-related disruption of the mineralization which causes the teeth to become porous with a decrease in proteins. This degradation of the teeth is thought to be from a breakdown of the matrix proteins and the way the by-products are drawn out from the aging enamel (Aoba and Fejerskov, 2002). There are different forms categorizing the severity of enamel fluorosis. Mild enamel fluorosis is seen as white striations or opaque patches while in moderate or severe cases the opaque spots extend and the porosity increases (NRC Ch.6,1993). If the damage is severe enough there can be many dental health issues, including an increase in caries later in life. These...

...Sticks and Stones May Break My Bones… The skeleton plays an important role in human physiology and function. Bone structure is vital as the human body rests on a framework made of bones. Healthy bones contribute to the overall health of an individual and a fully functional skeletal system is vital to physical health. Bones can get infections and other diseases just like any other part or organ of the human body. These illnesses can range from bone cancers to the degenerative bone disease of osteoporosis. This paper presents the disease of osteoporosis by defining it, and outlining its causes, symptoms, testing and diagnosis, and treatment. Bones consist of living tissue and are constantly being broken down and replaced. Bone building cells called osteoblasts help to build and strengthen bones while bone cells called osteoclasts role is to reabsorb bone cells. This process is constant throughout one’s lifetime. Osteoporosis is a disease characterized by reduced bone strength that makes it more vulnerable to fracture. Bone strength is measured by establishing bone mineral density (BMD), which is also called bone mass. People suffering from osteoporosis have low bone mass. Osteoporosis is a significant health problem that affects more than 25 million people in the United States alone. 80% of those affected by osteoporosis are women. (Melton) Osteoporosis is most prevalent in women 50 years and older. Osteoporosis is also responsible for numerous fractures around bones such as...

...Polycaprolactam Student Name: Syed Ali Shahid, ID Number # 20595181; email: sashahid@uwaterloo.ca 1. Introduction and Applications Polycaprolactam or PA 6 is a synthetic polyamide commonly recognized by its trade name Nylon 6. Polyamides or nylons are polymers characterized by the amide group –CONH-as recurring part of their polymer chain. The original nylon was first made in a laboratory in DuPont, USA in 1935 by Wallace Carothers. It was recognized as the first semicrsytalline polymer, the first engineering thermoplastic, and the first synthetic fiber .Amongst various variants of polyamide, polycaprolactam is particularly different in that it is made from only 1 kind of monomer- caprolactam which will be discussed in this paper in further detail from various aspects. Schalak while working on polyamides in IG Fabraen laboratory synthesized polycaprolactam through ring opening polymerization of caprolactom. He heated caprrolactam in a flask to about 250oC with about 5-10% water which hydrolyzed a few percent of the caprolactam to aminocaproic acid. The NH2 group of the aminocaproic acid acted as ring opening initiator for polycaprolactam followed by a polycondensation reaction of the NH2 and COOH group of the low molecular weight product of the ring opening polymerization reaction resulting in a high molecular weight product-Polycaprolactam. The key properties of polycaprolactam that have made them suitable for a variety of industrial applications are toughness, fatigue...
