Student Works (2010-2019)

Free radical-induced oxidative stress is involved in the pathogenesis of a number of human diseases such as diabetes mellitus, hypertension and atherosclerosis. Endothelial dysfunction, usually assessed as decreased endothelium-dependent vasodilation, precedes clinically before obvious vascular pathologies and together with oxidative stress are major predictors of disease progression. Such endothelial dysfunction is observed early in the development of the pathology and is due, at least in part, to an excessive vascular formation of reactive oxygen species (ROS) in particular superoxide anion (O2−), which reduce nitric oxide (NO) bioavailability. Epidemiological and clinical studies have demonstrated that a growing list of natural products, …

Modeling Undesirable Factors In Efficiency Evaluation With An Application To The Malaysian Manufacturing Sector / Noor Asiah Bt Ramli, Noor Asiah Ramli

Student Works (2010-2019)

Efficiency measurement must reflect the realities of production activities. In the manufacturing sector, emissions from fossil fuel combustion, which are acknowledged as being undesirable outputs, should be taken into account in efficiency measurement, since they are produced jointly with desirable outputs. This type of measurement is referred to as eco-efficiency. To analyze eco-efficiency, the Directional Distance Function (DDF) has been a popular approach. However, there is a drawback to the DDF model where the direction vector to the production boundary is fixed arbitrarily, and, hence, may not provide the best efficiency measures. The main purpose of this study is twofold. …
