Kim Alley a professional international model. In 1995 Alley was asked to work as an agent for Paris USA Models in New York City. For the next 10 years, Alley worked steadily as an agent for other companies in New York City, such as Bryan Bantry, APM Models and Elite Models. While working at these agencies, Alley managed the careers of many celebrities, stylists, photographers and models. In 2009 Alley started and produced "Virginia's Top Model" a Richmond, VA competition closely resembling "America's Next Top Model." The purpose of "Virginia's Top Model" was to spotlight one deserving contestant and take his or
Polycrystalline silicon grain boundaries, see figure 1. The resistivity, mobility, and free-carrier concentration in monocrystalline silicon vary with doping concentration of the single crystal silicon. Whereas the doping of polycrystalline silicon does have an effect on the resistivity, mobility, and free-carrier concentration, these properties strongly depend on the polycrystalline grain size, which is a physical parameter that the material scientist can manipulate. Through the methods of crystallization to form polycrystalline silicon, an engineer can control the size of the polycrystalline grains which will vary the physical properties of the material. The use of polycrystalline silicon in the production of solar cells requires
