Development of a non-destructive fluorescence technique for analysis of contact lens deposition levels

The primary objective of this research has been to determine the potential of fluorescence spectroscopy as a method for analysis of surface deposition on contact lenses. In order to achieve this it was first necessary to ascertain whether fluorescence analysis would be able to detect and distinguish between protein and lipid deposited on a lens surface. In conjunction with this it was important to determine the specific excitation wavelengths at which these deposited species were detected with the greatest sensitivity. Experimental observations showed that an excitation wavelength of 360nm would detect lipid deposited on a lens surface, and an excitation wavelength of 280nm would detect and distinguish between protein and lipid deposited on a contact lens. It was also very important to determine whether clean unspoilt lenses showed significant levels of fluorescence themselves. Fluorescence spectra recorded from a variety of unworn contact lenses at excitation wavelengths of 360nm and 280nm indicated that most contact lens materials do not fluoresce themselves to any great extent. Following these initial experiments various clinically and laboratory based studies were performed using fluorescence spectroscopy as a method of analysing contact lens deposition levels. The clinically based studies enabled analysis of contact lenses with known wear backgrounds to be rapidly and individually analysed following discontinuation of wear. Deposition levels in the early stages of lens wear were determined for various lens materials. The effect of surfactant cleaning on deposition levels was also investigated. The laboratory based studies involved comparing some of the in vivo results with those of identical lenses that had been spoilt using an in vitro method. Finally, an examination of lysosyme migration into and out of stored ionic high water contact lenses was made.

Vision2020 and the English language : a study of the role of language in national development.

The research reported here is an investigation into the problems of social and economic development of a multiethic and multicultural country which has the added challenge of adopting a non-indigenous code to facilitate the development process. Malaysia's power to negotiate outcomes favourable to the interest of the country is critical for the successful attainment of the goals and objectives of VISION2020. Therefore the mechanisms of the human resource development programme have to be efficacious. The three hypotheses of this study are as follows: 1. there is a fear that the problems and challenges posed by the development plans, have been conceptually trivialised; 2. based on (1) above there is a concern that solutions proposed are inadequate and inappropriate and 3. the outcome of both (1) and (2) can lead to the potential underachievement of national goals and objectives. The study proposes a complex model for conceptualising the problem which looks at the relationship between society and language, which any solutions proposed must take into proper consideration. The study looks at the mechanisms available for the smooth absorption of new Malaysian members to new and international communities. A large scale investigation was undertaken with the researcher functioning as a participant observer. An in-depth study of one particular educational ecology yielded approximately 38 hours of interviews and 100 questionnaires. These data were analysed both for explicit information and implicit implications. By some criteria national policies appear to be having the desired effect, and can be given a clean bill of health. By others it is clear that major adjustments would be necessary if the nation is to achieve its objectives in full. Based on the evidence gathered, thr study proposes an apprenticeship approach to training programmes for effective participation of new members in the new ecologies.

Enhanced renewable energy adoption for sustainable development in India:interpretive structural modeling approach

Poverty alleviation and social upliftment of rural India is closely linked with the availability and use of energy for development. At the same time, sustainable supply of clean and affordable renewable energy sources is required if development is to be sustainable, so that it does not cause any environmental problems. The purpose of this paper is to determine the key variables of renewable energy implementation for sustainable development, on which the top management should focus. In this paper, an interpretive structural modeling (ISM) - based approach has been employed to model the implementation variables of renewable energy for sustainable development. These variables have been categorized under ‘enablers’ that help to increase the implementation of renewable energy for sustainable development. A major finding of this research is that public awareness regarding renewable energy for sustainable development is a very significant enabler. In this paper, an interpretation of variables of renewable energy for sustainable development in terms of their driving and dependence powers has been examined. For better results, top management should focus on improving the high-driving power enablers such as leadership, strategic planning, public awareness, top management support, availability of finance, government support, and support from interest groups.

Heterogeneous catalysts for clean technology:spectroscopy, design, and monitoring

Reactive, but not a reactant. Heterogeneous catalysts play an unseen role in many of today's processes and products. With the increasing emphasis on sustainability in both products and processes, this handbook is the first to combine the hot topics of heterogeneous catalysis and clean technology. It focuses on the development of heterogeneous catalysts for use in clean chemical synthesis, dealing with how modern spectroscopic techniques can aid the design of catalysts for use in liquid phase reactions, their application in industrially important chemistries - including selective oxidation, hydrogenation, solid acid- and base-catalyzed processes - as well as the role of process intensification and use of renewable resources in improving the sustainability of chemical processes. With its emphasis on applications, this book is of high interest to those working in the industry.
