The USA is rich in data sources that are freely available. Rates of bank erosion, meander migration, channel width, riparian vegetation and watershed land use and cover conditions...
متن کاملQuasi-Static Deformation of a Uniform Thermoelastic Half –Space Due to Seismic Sources and Heat Source
This paper investigates the quasi-static plane deformation of an isotropic thermoelastic half-space due to buried seismic sources and heat source. Governing equations of thermo-elasticity are solved to obtain solutions for seismic sources in a thermoelastic half-space. The general solutions are acquired with the aid of Laplace and Fourier transforms and with the use of boundary conditions. The ...

As a reference variety, Received Pronunciation (RP), a non-regional accent of British English, is extensively described both in terms of synchronic variation and its historical development. There is a long tradition of describing changes over time in the traditional phonemic framework. However, modern corpus-based acoustic investigations have not been attempted on material older than the 1950s ...
