The present invention provides radiation sensitive compositions and methods that comprise novel means for providing relief images of enhanced resolution. Flushing large cache to a disk drive may consume large amounts of time. When the leakage current is detected, a maximum conduction rate set by the maximum conduction rate restricting circuit is changed from a small value at low rotation speeds to a large value. The selected component ratio will enable to improve the fuel stability in transportation and storage, expand the range of available fuels and increase the production volumes of quality fuels, while rationally using poor-quality products readily available at refineries.
