Gail Vittori, codirector of the Center for Maximum Potential Building Systems, suggested several methods, among them eliminating interior finish materials that offgas volatile organic compounds, using recycled fly ash as a substitute for concrete, labeling building products more thoroughly, and using paints certified by the independent Green Seal standards program.
Disc degeneration is a progressive process that involves two changes: exterior geometry change that includes a decreased disc height, growth of osteophyte, and diffused border between annulus and nucleus [ 7– 10] and interior material change that consists of increased nucleus stiffness, reduced water content, and changed permeability [ 11– 13].
The waveguide effect is counterbalanced as the aircraft interior is comprised of materials that do not enhance the wave-guide propagation phenomenon; the floor is covered with a thick carpet while the seats are made of a non-reflective textile.
The interior is restrained in design and executed in materials that seem both higher in quality and better tailored than most cars in this class.
Some of the latter are partially filled with materials that may have upwelled from the moon's interior as a result of tectonic activity in the past.
Iridescence, interference of light either at the surface or in the interior of a material that produces a series of colours as the angle of incidence changes.
Yumi Yi, for example, was designing a fully customizable interior, with color-coordinated materials that you might be able to match to, say, your handbag or hair color.
"We're pleased with the performance of the Cobalt in this report," said Doug Pickett, engineering group manager for interior materials at G.M. "The fact that six of the best vehicles by type are from G.M. shows that this issue has been important to us for a while".
Around windows, headlights and interior trim, automakers are using materials that mimic chrome but save weight and expense.
The new Malibu's seats will be considerably better than the current car's, and G.M. promises interiors made of higher-quality materials that fit together better.
