Embodiments of the present invention relate to methods and systems for detecting and removing a clogging condition of a filter in a dishwasher. 5 cm, fruit weight of about 20 to 30 grams, and ability to set fruit under relatively hot conditions. Another method includes orally administering to a BPH patient an inhibitor of steroid 5-reductase, and orally administering to the patient a therapeutically effective amount of 13-cis-retinoic acid. In one technique, a group of multiple predicates of a query are treated as a single predicate. Landmark features are extracted from two-dimensional sensor images and correlated to landmark features data stored in a database to estimate latitude, longitude, and altitude of a vehicle or missile. The output value corresponds to the postcondition.
