According to the American Cancer Society, in 1997, approximately 180,200 new cases of breast cancer were diagnosed, and 43,900 women were expected to die from this disease. When breast cancer is diagnosed early, a woman has a greater chance for survival. But if a woman does not know her risks for breast cancer, she may underestimate her risk and delay these vital screenings. A questionnaire has been prepared to assess how women view risk, in general, their own risk for breast cancer, and the results of an American Cancer Society Breast Cancer Risk Assessment test. The resulting data will be analyzed to answer the following questions.
Vapor pressure plays a major rule in the life and formation of secondary organic aerosol.
There is limited data available for the vapor pressures and behaviors of many species which make up secondary organic aerosol. Over the past two years there has been an increase in the amount of research done relating to the evaporation of species making up secondar organic aerosol, specifically those containing a binary mixture of adipic and glutaric acids. Since there is little if any data to compare new experimental results to, mathematical models were developed in order to simulate evaporation to determine evaporation times. The model was developed using MathSoft s MathCad. Equations for the evaporation of binary liquid particles were derived and used in the model.
