High Performance Plastic Substrates for Active Matrix Flexible FPD

The development of flexible and robust plastic displays will lead to enhancements in both the variety and usage of display products. In particular, flexibility opens up to an entirely new display market where conformability and wearability are leader concepts.

REBOUND Specification and application instructions

Rebound has been in successful use since the mid-seventies in squash courts throughout Europe, Asia & the World and has earned the approval of Squash England, ESRF, & WSF.

It has become clear over the years that, despite the efforts of bodies like Squash England to standardise specifications, basic errors are still common. It is the purpose of this paper to provide guidance for specifiers of Rebound, and, we hope, to act as a source of more general information.

ENGINEERING SOIL CLASSIFICATION

Earth, or soil, in the engineering sense, is defined as “any unconsolidated material that is the product of weathering and mechanical disintegration of rocks, composed of discrete particles with gases and liquids interspersed between them”.

Classification of soils

Soil mechanics is concerned with particulate materials (soils) found in the ground that are not cemented and not greatly compressed. These soils usually have a sedimentary origin, however, they can also occur as the result of rock weathering without any transport of the particles.
