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
Dirichlet eta function the formula_19 function is then analytic for formula_15, a region which includes the line formula_8. Now we can define correctly, where the denominators are not zero, or Since formula_24 is irrational, the denominators in the two definitions are not zero at the same time except for formula_25, and the formula_26 function is thus well defined and analytic for formula_15 except at formula_25. We finally get indirectly that formula_29 when formula_13: An elementary direct and formula_32-independent proof of the vanishing of the eta function at formula_13 was published by J. Sondow in 2003. It expresses the value of the eta function
