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
Hurwitz zeta function function of the complex argument "s" ("vide supra"), leading in each case to the difficult study of the zeros of Riemann's zeta function. In particular, there will be no zeros with real part greater than or equal to 1. However, if 0<"q"<1 and "q"≠1/2, then there are zeros of Hurwitz's zeta function in the strip 1<Re("s")<1+ε for any positive real number ε. This was proved by Davenport and Heilbronn for rational or transcendental irrational "q", and by Cassels for algebraic irrational "q". The Hurwitz zeta function occurs in a number of striking identities at rational values. In particular, values in
