An Analysis Of The Influence Of Speed On Fatal Accidents In Ohio, Megan Johnson

Williams Honors College, Honors Research Projects

Through data collected by NHTSA and FARS, Ohio crash data resulting in fatalities were analyzed through four different breakdowns to determine variables correlating to the fatalities. The breakdowns include dividing data from overall Ohio data, reports involving speeding, then from there to single-vehicle crashes. That data was divided down to only include male drivers and then finally only motorcycles. This data was analyzed as it was broken down to find trends with each category. Through these analyses, the trends were developed to suggest recommendations to implement through education and laws to help reduce the number of crashes resulting in fatalities.

Defining The Proper Operating Time For The Septa Extractor, Abigail Jones

Williams Honors College, Honors Research Projects

Anionic polymerizations are a common type of reaction used to produce synthetic rubber. During these reactions, it is necessary to charge initiators, modifiers, and other substances, through pressurized containers that are sealed with rubber septa. These septa prevent oxygen and moisture from entering the pressurized container, and the reactor, though they need to be cleaned before use to remove other impurities. Currently a glass Soxhlet Extractor is used to remove such impurities, and though effective, it has a limited capacity, so it has to run frequently. This limitation led to the commissioning of the Septa Extractor, which is an automated …

Architectural Paint Tank Cleaning, Callie Ruppen

Williams Honors College, Honors Research Projects

Architectural paint is highly susceptible to bacterial contamination, so material preservative ingredients are added during production to prevent bacterial contamination which can lead to wet-state spoilage of paint. In recent years however, paint formulations have reduced or eliminated volatile organic compounds (VOC) and regulations on the use of material preservative ingredients have been increased, reducing the use of traditional material preservatives. As a result, the coating industry must focus on improving microbial control through manufacturing hygiene programs including process tank cleaning and sanitization. While requirements for tank cleaning are clearly outlined in standard operating procedures (SOPs) and internal standards, there …
