In this paper we consider optimal edge colored complete graphs. We show that in any optimal edge coloring of the complete graph Kn, there is a Hamilton cycle with at most √ 8n different colors. We also prove that in every proper edge coloring of the complete graph Kn, there is a rainbow cycle with at least n/2−1 colors (A rainbow cycle is a cycle whose all edges have different colors). We show ...

In a basis of the space-time coordinate frame four quaternions discovered by Hamilton can be used. For subsequent reproduction these are expanded to 4 × matrices with real-valued matrix coefficients ?0 and 1. This group set is isomorphic SU(2) group. Such introduces extra six degrees freedom matter motion in space-time. There three rotations about space axes boosts along axes. Next one declares...

OBJECTIVES To assess the efficacy and safety of hypericum extract (STEI 300, Steiner Arzneimittel, Berlin) compared with imipramine and placebo in patients in primary care with a current episode of moderate depression. DESIGN Randomised, double blind, multicentre, parallel group trial for 8 weeks. SETTING Trained panel of 18 general practitioners from four German states: Bavaria, Berlin, Rh...

AIM To assess the effect of hormone replacement therapy on postoperative depression and anxiety symptoms. METHODS In observational prospective study 80 women divided into two groups were evaluated: women who received estrogen and androgen replacement therapy after hysterectomy with bilateral oophorectomy before onset of menopause (35-45 years old) and a control group that consisted of perimen...

BACKGROUND A major depressive episode diagnosed according to DSM-IV criteria can be accompanied by symptoms that DSM-IV does not include. These symptoms are sometimes classified as comorbidities. Our study assessed altered behavioral modes during a major depressive episode; ie, if 1 or more modes of behavior operated less or even not at all ("never"), or if the operation of others was more freq...

A previous study of 22 medical patients with DSM-III-R-defined anxiety disorders showed clinically and statistically significant improvements in subjective and objective symptoms of anxiety and panic following an 8-week outpatient physician-referred group stress reduction intervention based on mindfulness meditation. Twenty subjects demonstrated significant reductions in Hamilton and Beck Anxie...
