An apparatus for heating steam formed from cooling water in a heat exchanger for hot gas, having a super heater arranged in the heat exchanger vessel, a process for heating steam performed in such an apparatus, and a process for gasification of a hydrocarbonaceous feedstock having such a process for heating steam. In particular embodiments, a geocell is used as the geosynthetic article. The composition is comprised of various edible items, such as seeds and non-edible items such as pumice, volcanic ash, and calcareous sand. Substitute content includes a blank screen, prestored contents, a screen saver, alternative server content, and user selected content. The recommender generates a recommendation for a social graph connection between the two or more users in a social graph based on the alignment. The method according to the invention, includes at least one signal detection step, in the course of which Np detection windows Dj encompassing the time chips defined by the chip numbers are to be examined in search of an expected pulse sequence.
