Electron g-2 in Light-Front Quantization
Basis Light-front Quantization has been proposed as a nonperturbative
framework for solving quantum field theory. We apply this approach to Quantum
Electrodynamics and explicitly solve for the light-front wave function of a
physical electron. Based on the resulting light-front wave function, we
evaluate the electron anomalous magnetic moment. Nonperturbative mass
renormalization is performed. Upon extrapolation to the infinite basis limit
our numerical results agree with the Schwinger result obtained in perturbation
theory to an accuracy of 0.06%.Comment: 6 pages, 4 figure

Electron in a transverse harmonic cavity
We employ Hamiltonian light-front quantum field theory in a basis function
approach to solve the non-perturbative problem of an electron in a strong
scalar transverse confining potential. We evaluate both the invariant mass
spectra and the anomalous magnetic moment of the lowest state for this
two-scale system. The weak external field limit of the anomalous magnetic
moment agrees with the result of QED perturbation theory within the anticipated
accuracy.Comment: 4 pages, 3 figures, published versio

Environmental Recordkeeping Calendar for Drycleaning Facilities
The Iowa Air Emissions Assistance Program (IAEAP) at the Iowa Waste Reduction Center (IWRC), supported by the Iowa Department of Natural Resources (DNR), is pleased to present the 2016-2017 Environmental Recordkeeping Calendar for Dry Cleaning Facilities. The use of hazardous chemicals in the dry cleaning process, including perchloroethylene (commonly known as perc), can pose safety and environmental concerns if not managed appropriately. In an effort to minimize these concerns state and federal regulations are in place that may apply to your facility. These regulations have been developed to ensure your business operations will not unexpectedly harm the environment or individuals. The use of this calendar will assist you in implementing and tracking your business\u27s efforts to comply with hazardous waste regulations and the Environmental Protection Agency’s National Emission Standards for Hazardous Air Pollutants (NESHAP) for dry cleaners (40 CFR Part 63 Subpart M). NESHAP records must be kept at your facility for 5 years and the hazardous waste records for 3 years. The calendar will allow you to: • Record results of required leak checks and equipment monitoring; • Maintain records for refrigerated condensers and adsorbers; • Track perc purchases and annual usage; • Document monthly hazardous waste generation; and • Organize and document compliance in the event of a DNR or EPA inspection. While this calendar is not inclusive of all environmental regulations that may apply to your facility, it will serve as a good starting point for tracking important information related to environmental compliance.https://scholarworks.uni.edu/iwrc_facbook/1007/thumbnail.jp
Pollution Prevention Implementation Plan for Printing Industries
The Pollution Prevention Implementation Plan for Printers was prepared as part of the Iowa Pollution Prevention Initiative (IPPI) pilot project. IPPI demonstrated the team approach to small business pollution prevention technical assistance through integration of existing Iowa Small Business Development Center and Iowa Waste Reduction Center services. This cooperative effort was designed to help small businesses learn about and implement pollution prevention through recognition of pollution prevention options, comparison of costs and benefits, and evaluation of financing options. The Pollution Prevention Implementation Plan (PPIP) for Printers provides: • An overview of pollution prevention options, • A review of the costs and benefits associated with these options, and • Steps for pollution prevention implementation and financing Use of the PPIP will help a small business select pollution prevention practices that have a high probability of being successful from quality/production, environmental and economic standpoints. While this particular PPIP addresses the printing industry, other PPIP’s are available for metal manufacturing and vehicle maintenance facilities. Many pollution prevention options recommended for lithographic printing can be adapted to all types of printing shops and printing methods.https://scholarworks.uni.edu/iwrc_facbook/1012/thumbnail.jp
