An optical compensatory sheet comprises a cellulose acetate support and an optically anisotropic layer. The mobile support structure is displaceably mounted on the fixed support structure by one or more bearings. The invention further relates to genetic complements of plants of variety CH402830. Each of the plurality of nodes is adapted to communicate data over a linear bus. The formulations are particularly useful in the production of a range of goods from semi-rigid to highly flexible materials and are particularly useful in the production of medical materials such as blood bags and tubing. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated andor degraded within the GI tract.
