Method for conditioning a load bearing surface and a surface formed thereby
A method for conditioning a load bearing surface includes positioning an oriented polymeric membrane in a mount and applying a force to the polymeric membrane so as to create a stress in the membrane. The stressed membrane is heated to a temperature no less than about a temperature that the load bearing surface is expected endure in use. The membrane is maintained at the temperature for a first period of time sufficient to heat the entirety of the membrane and the it is cooled while maintaining the stress on the membrane. Following a predetermined cool down period, the applied stress is removed for availability of the end use product. A seating surface for use in a vehicle that is subjected to an elevated temperature is also disclosed.

LIQUID CRYSTAL DISPLAY DEVICE, POLARIZATION PLATE AND POLARIZER PROTECTION FILM
The invention provides a liquid crystal display device, a polarizer, and a protective film that enable suppression of the occurrence of rainbow unevenness to improve visibility in a liquid crystal display device including a backlight light source comprising white-light-emitting diode having an emission spectrum that has one or more peak tops in each of the blue region (400 nm or more and less than 495 nm), the green region (495 nm or more and less than 600 nm), and the red region (600 nm or more and 780 nm or less). The protective film contains a polyethylene terephthalate-based resin film that has a retardation of 3000 to 30000 nm, wherein the CTF value of periodic unevenness of the x value of chromaticity at an observation angle of 55 degrees is 1.2 or less.
Method of making an integral geogrid from a coextruded multilayered polymer starting material
An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosynthetic reinforcement.
