CONTEXT Myocardial injury during cardiac surgery on cardiopulmonary bypass (CPB) is a major determinant of morbidity and mortality. Preclinical and clinical evidence of dose- and time-related cardioprotective effects of volatile anesthetic drugs exist and their use during the whole surgery duration could improve perioperative cardiac protection. Even if administering volatile agents during CPB ...

In this research, Chapter 1 is dedicated to analytical evaluation of landfill gas recovery. The majority of the world's municipal solid waste in is still going to the landfills, US being no exception. According to BioCycle and Earth Engineering Center, about 270 million tons of waste are landfilled annually in US. Anaerobic degradation, a naturally occurring process on the landfills, generates ...

Pauling and Miller have independently proposed that the presence of an anesthetic gas in tissue induces a cage-like arrangement of hydrogen-bonded water molecules. The theories recognize that most gas-hydrate crystals would not form at the temperature and pressure that exist during anesthesia and propose that other components of tissue such as protein should have a stabilizing effect. Measureme...

This paper addresses the existence of an Environmental Kuznets Curve for China, using a sample of 30 regions, covering the period 1982–1997. The types of pollution included are wastewater, waste gas, and solid waste. We consider the development of the sources of pollution in a pooled cross-section analysis with pollution in absolute levels, in per capita terms, and relative to real Gross Region...

This study analyzes the climate change and economic impacts of food waste in the United States. Using lossadjusted national food availability data for 134 food commodities, it calculates the greenhouse gas emissions due to wasted food using life cycle assessment and the economic cost of the waste using retail prices. The analysis shows that avoidable food waste in the US exceeds 55 million metr...

Landfill Gas to Energy This research investigates the utilization of landfill gas, an abundant waste product, by reforming it to syngas that can be converted to liquid fuels using Fischer Tropsch or to a H2 rich stream using water-gas shift. 65% of the 413 million tons of municipal solid waste (MSW) generated per year in the United States is landfilled, and 67% of the landfilled MSW is composed...

Waste management has at least Ž ve types of impacts on climate change, attributable to: (1) landŽ ll methane emissions; (2) reduction in industrial energy use and emissions due to recycling and waste reduction; (3) energy recovery from waste; (4) carbon sequestration in forests due to decreased demand for virgin paper; and (5) energy used in long-distance transport of waste: A recent USEPA stud...
