Appraisers and the Fair Housing Law: Accessibility Requirements for the Disabled

In 1988 the Fair Housing Act of 1968 was amended to include the "handicapped" as being protected from discrimination in multiunit housing. The three general categories of discriminatory acts are refusal to make or allow reasonable physical modifications to a covered multiunit dwelling, refusal to make reasonable accommodations in rules and practices, and failure to follow certain design and construction standards. The U.S. Department of Housing and Urban Development has issued Fair Housing Accessibility Guidelines, which provide technical guidance on multiunit dwelling design and construction standards. This study examines these guidelines and the impact the Act may have upon value when discriminatory practices are observed.

Method for Computing Short-Range Forces between Solid-Liquid Interfaces Driving Grain Boundary Premelting

We present a molecular dynamics based method for computing accurately short-range structural forces resulting from the overlap of spatially diffuse solid-liquid interfaces at wetted grain boundaries close to the melting point. The method is based on monitoring the fluctuations of the liquid layer width at different temperatures to extract the excess interfacial free-energy as a function of this width. The method is illustrated for a high energy Sigma 9 twist boundary in pure Ni. The short-range repulsion driving premelting is found to be dominant in comparison to long-range dispersion and entropic forces and consistent with previous experimental findings that nanometer-scale layer widths may only be observed very close to the melting point.Comment: 5 pages, four figure
