Methods are provided for refining natural oil feedstocks and partially hydrogenating polyunsaturated olefins and polyunsaturated esters. The method is exemplified herein in an improved batch process and apparatus for the thermal decomposition of hydrocarbon containing material in a sealed reactor interior. In another embodiment, a method comprises system firmware determining that an LOL is detected for a lockstep pair of processors that are assigned the role of boot processor in a system. Intratendinous injections were performed to determine the optimal concentration for in vivo expression. The blocks are matched based upon their content and their local neighborhoods.
