The Chemical And Mechanical Effects Of Binding Chitosan To Implant Quality Titanium, Holly Joy Martin Dec 2006

The Chemical And Mechanical Effects Of Binding Chitosan To Implant Quality Titanium, Holly Joy Martin

Theses and Dissertations

Biomedical implants are commonly made from commercially pure titanium and other metal alloys, which are chosen for their strength and density. To improve the stability and promote bone cell growth into the implant, efforts to bond coatings to metal have been extensively studied. Many coatings used are considered bioactive, which promote the adhesion and growth of the bone cells surrounding the implant [A.1]. Of these, the most commonly investigated coating is a ceramic called hydroxyapatite, which is brittle, leading to flaking and inadequate bone cell growth [A.2]. Alternate bioactive coatings are being examined, including chitosan, the deacetylated form of chitin. …

Measures Of Oxidation Of Soybean And Catfish Oils, John Michael Mcgillivray Dec 2006

Measures Of Oxidation Of Soybean And Catfish Oils, John Michael Mcgillivray

Theses and Dissertations

Oils from soybeans and catfish by-products were extracted using hexane, propane, and supercritical carbon dioxide (SCCO2). Free fatty acids (FFA), peroxide values (PV), anisidine values (AnV), total oxidation (TOTOX), induction point (IP), iodine values (IV), and 2-thiobarbituric acid reactive substance (TBARS) were all measured to analyze oxidation of these oils. The extraction yield of propane, hexane, and SCCO2 oils was 80.4, 94.5, and 90%, in respect to total lipid content. Oils extracted with SCCO2 were more oxidized than those extracted with propane and hexane; probably due to the higher temperature and longer extraction time. The IP correlated with AnV, IV, …

Clustering Multiple Contextually Related Heterogeneous Datasets, Mahmood Hossain Dec 2006

Clustering Multiple Contextually Related Heterogeneous Datasets, Mahmood Hossain

Theses and Dissertations

Traditional clustering is typically based on a single feature set. In some domains, several feature sets may be available to represent the same objects, but it may not be easy to compute a useful and effective integrated feature set. We hypothesize that clustering individual datasets and then combining them using a suitable ensemble algorithm will yield better quality clusters compared to the individual clustering or clustering based on an integrated feature set. We present two classes of algorithms to address the problem of combining the results of clustering obtained from multiple related datasets where the datasets represent identical or overlapping …

Patent Political Economy - Indian Lessons On Pharmaceutical Patent, Julien L. Chaisse, Samira Guennif Dec 2006

Patent Political Economy - Indian Lessons On Pharmaceutical Patent, Julien L. Chaisse, Samira Guennif

ExpressO

The Intellectual Property Rights (IPR) regime adopted by any country is essentially a tool that strives to ensure both the growth of the domestic pharmaceutical industry and people’s access to medicines. But, contrary to the very easily advanced theory, there is no paradox between the two. From this perspective, the Indian experience has shown that it is precisely the relaxation of its national IPR regime that promoted the growth of its domestic industry, thereby ensuring a better patient access to medicines. However, the globalisation process does not overlook any sector, which means that medicines too are submitted to the new …
