Abstract:
Solar ultraviolet radiation creates an ozone layer in the atmosphere which in turn completely absorbs the most energetic fraction of this radiation. This process both warms the air, creating the stratosphere between 15 and 50 km altitude, and protects the biological activities at the Earth's surface from this damaging radiation. In the last half-century, the chemical mechanisms operating within the ozone layer have been shown to include very efficient catalytic chain reactions involving the chemical species HO, HO 2 , NO, NO 2 , Cl and ClO. The NO X and ClO X chains involve the emission at Earth's surface of stable molecules in very low concentration (N 2 O, CCl 2 F 2 , CCl 3 F, etc.) which wander in the atmosphere for as long as a century before absorbing ultraviolet radiation and decomposing to create NO and Cl in the middle of the stratospheric ozone layer. The growing emissions of synthetic chlorofluorocarbon molecules cause a significant diminution in the ozone content of the stratosphere, with the result that more solar ultraviolet-B radiation (290–320 nm wavelength) reaches the surface. This ozone loss occurs in the temperate zone latitudes in all seasons, and especially drastically since the early 1980s in the south polar springtime—the ‘Antarctic ozone hole’. The chemical reactions causing this ozone depletion are primarily based on atomic Cl and ClO, the product of its reaction with ozone. The further manufacture of chlorofluorocarbons has been banned by the 1992 revisions of the 1987 Montreal Protocol of the United Nations. Atmospheric measurements have confirmed that the Protocol has been very successful in reducing further emissions of these molecules. Recovery of the stratosphere to the ozone conditions of the 1950s will occur slowly over the rest of the twenty-first century because of the long lifetime of the precursor molecules.

Abstract:
Stratospheric water vapor (SWV) changes play an important role in regulating global climate change, and its variations are controlled by tropopause temperature. This study estimates the impacts of tropopause layer ozone changes on tropopause temperature by radiative process and further influences on lower stratospheric water vapor (LSWV) using the Whole Atmosphere Community Climate Model (WACCM4). It is found that a 10% depletion in global (mid-low and polar latitudes) tropopause layer ozone causes a significant cooling of the tropical cold-point tropopause with a maximum cooling of 0.3 K, and a corresponding reduction in LSWV with a maximum value of 0.06 ppmv. The depletion of tropopause layer ozone at mid-low latitudes results in cooling of the tropical cold-point tropopause by radiative processes and a corresponding LSWV reduction. However, the effect of polar tropopause layer ozone depletion on tropical cold-point tropopause temperature and LSWV is opposite to and weaker than the effect of tropopause layer ozone depletion at mid-low latitudes. Finally, the joint effect of tropopause layer ozone depletion (at mid-low and polar latitudes) causes a negative cold-point tropopause temperature and a decreased tropical LSWV. Conversely, the impact of a 10% increase in global tropopause layer ozone on LSWV is exactly the opposite of the impact of ozone depletion. After 2000, tropopause layer ozone decreased at mid-low latitudes and increased at high latitudes. These tropopause layer ozone changes at different latitudes cause joint cooling in the tropical cold-point tropopause and a reduction in LSWV. Clarifying the impacts of tropopause layer ozone changes on LSWV clearly is important for understanding and predicting SWV changes in the context of future global ozone recovery.

Abstract:
This thesis examines the politics of international regime formation, with particular reference to the global atmospheric problems of ozone layer depletion and global warming. A review of the international relations literature reveals that there are three approaches to the study of international regime formation: global, state-centred and individualistic. Building upon these, three preconditions and four catalysts for international regime formation are proposed. Each of the hypothesised preconditions -- scientific consensus, tolerable domestic economics costs and global equity -- is necessary, though not by itself sufficient, for international regime formation. Meanwhile, although no one of the hypothesised catalysts -- political entrepreneurs, the solidity of the broader international political system, environmental pressure groups and the mobilisation of public opinion -- is a necessary element for the formation of an international regime, the presence of any one can nevertheless accelerate the rate at which regimes are formed. The theoretical framework that is proposed is applied to the histories of the ozone layer depletion and global warming issues. In this investigation, data up to the end of 1991 were considered. The thesis also considers some issues that extend beyond the end of 1991, for the nature of parts of the analysis precludes an unwavering commitment to this cut-off date. The findings of this investigation have both theoretical and empirical dimensions. First, because the application of the theoretical framework does not invalidate it, thinking about the formation of regimes in international society in general is advanced. And second, by applying the framework to these two particular issues, explanations are offered as to why an international regime had been formed by the end of 1991 to preserve the earth's ozone layer, while one to deal with global warming had not.

Abstract:
The purpose of this study was to investigate preservice science teachers&rsquo
mental models about the role and distribution of ozone layer and ozone layer depletion regarding their ontological orientation. This study was conducted with twenty four preservice science teachers who were enrolled in Elementary Science Education Program of Education Faculty of one public university located in Central Anatolia. From each grade level six preservice science teachers were selected
two from low achiever, two from middle achiever and two from high achiever. Moreover, in the study, data were collected by using semi structured interview and interview consists of eleven questions and with five questions having multiple parts. Interview recordings were transcribed and analyzed qualitatively. In the following steps of the analysis, researcher proceeded with the already formed and described codes in an easygoing way. The results revealed that preservice science teachers&rsquo
responses were mostly seen as skin cancer and sunburn as harmful effects of ultraviolet rays and preservice science teachers&rsquo
responses were mostly seen as activation vitamin D and photosynthesis of plants as beneficial effects of Sun&rsquo
s rays. Half of preservice science teachers thought that ozone layer exists in the atmosphere. Moreover, preservice science teachers&rsquo
responses were mostly seen as perfume, deodorant, car, and spray as harmful materials to ozone layer. Chlorofluorocarbon, carbon monoxide, and carbon-dioxide were the most seen responses as harmful chemicals to ozone layer. Similar misconceptions were identified when compared with past studies. Also, different misconceptions were found in the study. Ten distinct models were formed regarding role and distribution of ozone layer and five distinct models were formed regarding ozone layer depletion. Moreover, absorbing and reflecting surface was mostly seen ontological belief regarding role and distribution of ozone layer. Hole was mostly seen ontological belief regarding ozone layer depletion. Generally, achievement and grade level did not make difference among preservice science teachers forming which type of mental models and having ontological beliefs.

Abstract:
The cooperation of developing countries is commonly assumed to be essential for the establishment of effective regimes to manage global environmental interdependence. Yet their policies and perceptions have been inadequately studied. This thesis seeks to partially fill this gap in the literature with a detailed analysis of Indian policy on global environmental issues. It examines the cases of ozone depletion, climate change, and loss of biodiversity, and discusses developments up to the 1992 Earth Summit. The study addresses four broad questions about Indian policy: the process of policy making; the character of Indian interests and preferences; the nature and evolution of India's bargaining strategy; and the outcome of international negotiations for India. It reveals a complex picture of continuity and change in Indian policy. It demonstrates the enduring importance of traditions and values such as the "poverty is the greatest polluter" orthodoxy and the concepts of sovereignty, equity and Third World solidarity. It also highlights the impact of perceptions of vulnerability in relation to the North. It argues that Indian policy did not reflect purely powermaximising goals; policy makers were sometimes uncertain about where India's interests precisely lay, and felt constrained both by economic weakness and by the recognition of the mutual interest of all states in global environmental protection. This was reflected in the moderation in India's bargaining strategy. The Indian case suggests that developing countries did not regard their cooperation in the resolution of global environmental issues purely as a bargaining chip with which to extract concessions from the North. Still less did they perceive these issues as providing an opportunity to pose a macro-challenge to the North, linking agendas across issue areas. Instead, their goals reflected perceptions of constraints and mutual interests in bargaining with the North. Their bargaining strategy thus tended to be moderate and flexible, unlike the confrontational approach of the 1970s.

Abstract:
Methyl halides are trace gases with both natural and anthropogenic origins. Once generated, these gases transport chlorine and bromine into the stratosphere, where they play an important role in ozone depleting catalytic cycles. The Florida Everglades is one location where methyl halide emissions have been proposed to be elevated due to high primary production and ionic halogens. This region also provides a unique study environment due to salt water intrusions, which occur during storm or low marsh water level-high tide events. The purpose of this research was twofold. First, quantification of methyl chloride (CH3Cl) and methyl bromide (CH3Br) production from periphyton mats on a temporal scale was needed. Secondly, to determine how varying concentrations of salinity affect CH3Cl and CH3Br production originating from calcareous periphyton mats within the Everglades. Periphyton was exposed to continuous 12 hour dark/light cycles in varying concentrations of salt water (0, 0.1, 1, 5, and 10 parts per thousand). All water samples were analyzed to determine the production rate of CH3Cl and CH3Br in periphyton samples using a gas chromatograph coupled with an electron capture detector (GC-ECD). Periphyton mats were found to be a producer of CH3Cl in all freshwater (0 parts per thousand) trials and sampling times; however, results from CH3Br analysis found production rates that suggest consumption occurred in the majority of the 0 parts per thousand trials. Production rates for CH3Cl ranged from 0.077 to 0.109 g-1hr-1 after 24 hours, 0.027 to 0.073 pM g-1hr-1 after 48 hours, and 0.034 to 0.047 pM g-1hr-1 after 72 hours. Production rates for the CH3Br freshwater experiments ranged from -0.00025 to 0.00185 pM g-1hr-1 after 24 hours, -0.00022 to -0.00078 pM g-1hr-1 after 48 hours, and -0.00042 to -0.00061 pM g-1hr-1 after 72 hours. This research has also shown that increased salinity does have a significant positive effect on the production of CH3Cl and CH3Br from calcareous periphyton mats, which is important in areas that could be prone to salt water intrusions or rising sea levels due to global climate change.

Abstract:
In polar spring, tropospheric ozone depletion is related to the presence of halogen oxide concentrations in the atmospheric boundary layer. Halogen oxides such as BrO participate in an autocatalytic chemical reaction cycle, leading to the release of Br2 and BrCl from the fresh sea ice. The paper presents the identification of a detailed chemical reaction mechanism for the ozone depletion event, where bromine plays the major role. The heterogeneous reactions in the chemical reaction mechanism are studied in detail, and a sensitivity analysis is performed to identify the importance of each reaction in the mechanism. A skeletal reaction scheme is identified on the basis of the sensitivity analysis,. This skeletal chemical reaction mechanism then is used in a 3-D large eddy simulation (LES) with the Smagorinsky sub-grid model. The configuration studied includes a mountain located at the ground above which the ozone depletion is studied. In this situation, the height of the boundary layer varies, which greatly affects the ozone depletion event.

Abstract:
Greater use of hydrocarbon fuel has led to fast depletion of fossil fuel reserves. This has now become worldwide problem making civilization vulnerable due to paucity of fuel in future. It is also a fact that as civilization is growing the use of transport has become essential part of life. The use of large number of vehicles for transport is contributing to about 70% of total air pollution, creating environmental & ecological imbalances. About 100–150 years old transport technology is totally based on combustions causing higher rate of emission, ultimately depleting the thickness of Ozone layer and causing the global warming. Thus worldwide fast depletion of conventional energy resources necessitates the search of alternatives such as Non-Conventional Energy Sources, Renewable Energy Sources and other Direct Conversion of Energy Sources. This paper deals with study on potential of renewable energy resources and their conversion system with emphasis on development of zero pollution engine for vehicles which may lead to sustainable future.

Abstract:
"The aim of this work is to compare the environmental impact of three different packaging systems for coffee capsules, which can be used in the same coffee machine. A comparative Life Cycle Assessment has been performed considering the following three types of coffee capsules: 1. Compostable coffee capsules packaged into a multichamber PET tray. 2. Capsules made of aluminium and packaged into cardboard boxes. 3. Capsules made of polypropylene with an aluminium top lid, singularly packaged in modified atmosphere into a bag made of multilayer film of aluminium and polypropylene. The functional unit considered is a coffee capsule. To evaluate the environmental impact, the EPD (Environmental Product Declaration) method is used. This work shows that it is possible to reduce the environmental impact of compostable capsules packaged in PET tray by two ways: by using a less polluting starch polymer and by producing biogas instead of compost from the organic waste. With these improvements, the compostable coffee capsule in PET tray results the less damaging packaging system for all categories except than for the ozone layer depletion and the fossil fuels depletion."

Abstract:
Gas-turbine combined-cycle (GTCC) power generation is clean and efficient, and its demand will increase in the future from economic and social perspectives. Raising turbine inlet temperature is an effective way to increase combined cycle efficiency and contributes to global environmental conservation by reducing CO2 emissions and preventing global warming. However, increasing turbine inlet temperature can lead to the increase of NOx emissions, depletion of the ozone layer and generation of photochemical smog. To deal with this issue, MHPS (MITSUBISHI HITACHI POWER SYSTEMS) and MHI (MITSUBISHI HEAVY INDUSTRIES) have developed Dry Low NOx (DLN) combustion techniques for high temperature gas turbines. In addition, fuel flexibility is one of the most important features for DLN combustors to meet the requirement of the gas turbine market. MHPS and MHI have demonstrated DLN combustor fuel flexibility with natural gas (NG) fuels that have a large Wobbe Index variation, a Hydrogen-NG mixture, and crude oils.
