Nankali's Masticatory Force Systematization force of the masticatory system and discovered the differences in the produced force, which was approximately doubled. The periodontal system controls automatically the measure of mastication force in this process and the jaw elevator muscles develop the main forces used in mastication. Dr. Weber worked out that 1 cm cross section surface area of any masticatory muscle can produce approximately 10 kg force. The following average surfaces were found: temporalis - 8 cm, masseter - 7.5 cm, and medial pterygoid - 4 cm which makes a total of 19.5cm. However, this force in some people is measured up to 3900N
The Name of the Rose fifty-six rooms. Each room has a scroll containing a verse from the Book of Revelation. The first letter of the verse is the letter corresponding to that room. The letters of adjacent rooms, read together, give the name of a region (e.g. Hibernia in the West tower), and those rooms contain books from that region.
