Emetophobia Exposure methods, using video-taped exposure to others vomiting, hypnosis, exposure to nausea and exposure to cues of vomiting, systemic behavior therapy, psychodynamic and psychotherapy have also shown positive effects for the treatment of emetophobia. However, in some cases it may cause re-traumatization, and the phobia may become more intense as a result. Emetophobics may also suffer from other complicating disorders and phobias, such as social anxiety, fear of flying and agoraphobia. These three are very common, because people who fear vomiting are often terrified of doing so, or encountering it, in a public place. Therefore, they may restrict their social
Particular values of the Riemann zeta function for formula_24, For the first few odd natural numbers one has It is known that "ζ"(3) is irrational (Apéry's theorem) and that infinitely many of the numbers "ζ"(2"n" + 1) ("n" ∈ N) are irrational. There are also results on the irrationality of values of the Riemann zeta function at the elements of certain subsets of the positive odd integers; for example, at least one of "ζ"(5), "ζ"(7), "ζ"(9), or "ζ"(11) is irrational. The positive odd integers of the zeta function appear in physics, specifically correlation functions of antiferromagnetic XXX spin chain. Most of the identities following below are provided
