To provide a polyolefin based resin film of high elastic modulus and a composition for producing a polyolefin based resin film of high elastic modulus. A handle is attached to the top end of the frame. A plurality of base stations communicate with a base station controller at the dispatch center and a plurality of remote radios communicate with at least one of the remote terminals. The present invention presents a rolling technique to manufacture magnesium and magnesium alloy sheets with high plasticity. In this way no PN junctions are present inside the polycrystalline portion of the pseudo-epitaxial region and the structure has a high breakdown voltage. For each of the Synchronization Master references, a first path and a second path of the obtained paths are selected.
