It has been proved by experiments that the metal magnetic memory (MMM) NDT method can effectively detect the stress concentration of ferromagnetic metal parts. But it is still hard to evaluate the stress concentration quantitatively because of the confusion in the mechanism of MMM method. In this paper experiments are designed and carried out to investigate the relationship between the MMM sign...

Bounds on the trace mappings defined on the Sobolev space W 1 1 (Ω) and the space LD(Ω) of integrable stains are obtained. Such bounds correspond to stress concentration—the ratio between the maximal stress in a body and the maximum of the traction applied to its boundary. The analysis leading to the bounds may be described in the mechanical context of stress theory and stress concentration.

Mindfulness reflects an awareness of present moment experiences through an attitude of acceptance and openness (Bishop et al., 2004; Cardaciotto, Herbert, Forman, Moitra, & Farrow, 2008). Experiential avoidance, by contrast, refers to attempts to change, alter, or avoid private experiences (e.g., thoughts, feelings, sensations), and it is believed to underlie a number of psychopathologies, incl...

The aim of the present study was to examine potentially moderating effects of personality characteristics regarding changes in anxious and depressed mood associated with Mindfulness-Based Stress Reduction (MBSR), controlling for socio-demographic factors. Meditation-naïve participants from the general population self-presenting with psychological stress complaints (n = 167 participants, 70% wom...

Even though stress may be adaptive in the short run, prolonged stress reactions may have adverse effects on many different aspects of physical and mental health [1,2] and on cognitive performance [3]. Thus, the high prevalence of stress-related conditions is of considerable concern both from viewpoint of the burdens on the society they cause (i.e., in terms of health-care costs, costs for sick ...
