Description
This thesis seeks to evaluate whether the benefits of spinal fusion surgeries are worth their increasing costs. The paper examines the trends that contribute to these surgeries' increasing prices and then evaluates the customer impact of these surgeries in order to make a conclusion on whether the surgeries are worth it. This paper discusses the main factors that contribute to the increase in prices of these surgeries and these include the aging population, the increase in diabetes rates, and the practice of purchasing physicians owned distributorships (PODs) devices in some hospitals. The paper concluded that there is a definite correlation between the increased rate of spinal surgeries performed as a result of an increase in diabetes rates in the US population. It was argued that diabetes can lead to multiple spinal diseases which increase the demand of spinal surgeries which in turn causes the prices of these surgeries to rise. The paper also argued that current technological advances have allowed us to live longer which in turn leads to an increase in spine surgeries simply due to old age and a deteriorating spine. Lastly, it was argued that the recent surge in the POD devices being used in spinal surgeries in some hospitals can be seen as a possible influence to the increase in the cost of these surgeries. This is because the hospitals that chose to purchase surgery devices from PODs are more likely to increase the cost to perform the surgery because they are paying a lot more for those devices. Looking at the customer impact, it was apparent that spinal fusion surgeries carry certain risks because they require decortication of bone and, often, placement of implants; along with extensive dissection and longer operative time. However, based on the research conducted, there was no conclusion to be made on whether spinal fusions carried more risks than all other spinal surgeries because the data used only compared the surgery to some that are arguably less complicated like discectomies.

Description
Currently conventional Subtitle D landfills are the primary means of disposing of our waste in the United States. While this method of waste disposal aims at protecting the environment, it does so through the use of liners and caps that effectively freeze the breakdown of waste. Because this method can keep landfills active, and thus a potential groundwater threat for over a hundred years, I take an in depth look at the ability of bioreactor landfills to quickly stabilize waste. In the thesis I detail the current state of bioreactor landfill technologies, assessing the pros and cons of anaerobic and aerobic bioreactor technologies. Finally, with an industrial perspective, I conclude that moving on to bioreactor landfills as an alternative isn't as simple as it may first appear, and that it is a contextually specific solution that must be further refined before replacing current landfills.
