Traditional Chinese medicines derived from the human body "Three Corpses; demonic spirits believed to live in the human body and hasten death" and "gǔdú" 蠱毒 "gu poisoning"; a poison produced by venomous insects; cast a black magic spirit possession over someone". The first "Bencao gangmu" prescription for human nails is not from Chinese medical texts but from Daoist rituals for expelling what (Cooper & Sivin (1973: 220) describe as the "Three Corpse-Worms 三尸, the chief of the "inner gods" who are to the individual microcosm what the celestial bureaucracy is to the cosmos." Prescription 52.6.1, the 斬三尸法 "Method of Beheading the Three Corpses", involves supernaturally cutting the nails
Dynamic trimming Dynamic trimming A Dynamic trimming system operates seagoing vessels to achieve minimum water resistance under all circumstances. It is based on multidimensional analysis of real-time data collected on vessel attitude (trim). Dynamic trimming automates data retrieval from sensor networks, for vessel management software applications. The core of the method is a multidimensional analysis model, which continuously calculates the key forces affecting the vessel attitude. The system helps officers ensure that their vessels are operated efficiently. The key metrics are graphically displayed to facilitate decision-making. The system aims to continuously optimize vessel trim, thus minimizing water resistance and reducing fuel consumption.
