Approximate Approaches For Nuclear Weak Interaction Rates In Astrophysics, Benjamin M. Anderson Jan 2018

Approximate Approaches For Nuclear Weak Interaction Rates In Astrophysics, Benjamin M. Anderson

Bridges: A Journal of Student Research

Nuclear weak interactions, like beta decay, are important inputs for modeling astrophysical explosions. In the allowed approximation, these processes proceed as Fermi or Gamow Teller (GT) processes where the spins of the electron and neutrino are anti-parallel or parallel, respectively. In the GT case, transition probability is spread over many final states in the daughter nucleus, with each probability determination requiring numerical integration of the available phase space. Developing a fast and accurate method for calculating each contribution to the total decay rate would provide reliable weak rate libraries for astrophysical modelers. The phase space integrand includes the classical statistical …

The Clean Air Act And Its Impact On Ground Level Ozone Pollution Levels In Los Angeles, California, Rebecca Ford Jan 2018

The Clean Air Act And Its Impact On Ground Level Ozone Pollution Levels In Los Angeles, California, Rebecca Ford

Bridges: A Journal of Student Research

Ozone (O3) occurs as a photochemically produced pollutant in the troposphere and its emission and concentration is regulated by the Clean Air Act (CAA) of 1970. The Los Angeles area is an example of how O3 can be a public health hazard and taint a city’s aesthetics and quality of life through photochemical smog. This study was conducted to observe the overall effectiveness of the CAA. I explored daily O3 concentrations from 1980 to the present at three air quality monitoring stations in LA from the AirData database of the U.S. Environmental Protection Agency. National O3 standards were only exceeded …
