Microthin sheet technology is disclosed by which superior batteries are constructed which, among other things, accommodate the requirements for high load rapid discharge and recharge, mandated by electric vehicle criteria. The tissue graft composition may further comprise at least one macromolecule incorporated into the nanoparticle. The data block management device has a memory unit, a group reconfiguration unit and a medium selection unit. The detection is carried out by a polarization detection system which includes an optical splitter which is manufactured in simplified form for economic construction.
