Purpose. To develop an approach for determining the stress state of plate structural elements with holes under dynamic loads controlled accuracy. Methodology. The study was carried out on basis Laplace transform and method integral equations. Findings. An to stresses at in plates is proposed, which includes: time coordinate; a numerical transformants displacements based equations; finding origi...

Background of the research: A conventional box-type structure is generally used in constructing core/shear wall, internal frame, and steel box girders. Tube-in-Tube with single multiple tubes reduces shear lag effect lateral deformation a tall tubular structure. Purpose: However, present study focuses on behavior modified form beam, i.e., beam outstanding flanges. Thus, this analyzes flanges co...

This eight-week study examined the feasibility of offering weekly classes in Integrative Restoration (iRest), a form of mindfulness meditation, to military combat veterans at a community mental health agency in the San Francisco Bay Area. Participants were 16 male combat veterans (15 Vietnam War and 1 Iraq War) of mixed ethnicity, aged 41 to 66 years, suffering from posttraumatic stress disorde...

PURPOSE The aim of this study was to observe stress concentration in the implant, the surrounding bone, and other components under the pull-out force during the crown removal. MATERIALS AND METHODS Two 3-dimensional models of implant-supported conventional metal ceramic crowns were digitally constructed. One model was designed as a vertically placed implant (3.7 mm × 10 mm) with a straight ab...

It is thought that the stress concentration at the root apex caused by orthodontic force induces root resorption. The purpose of this study was to investigate stress distribution at the root in cases of deviated root shapes using finite element models (FEMs). To clarify this, five three-dimensional FEMs divided by deviated root shape (normal, short, blunt, bent root apex, pipette shape) were co...

Background and Aim: Different attachment designs have been developed to connect implant to natural teeth in partial dentures; however, adequate studies have not been performed to determine stress distribution patterns in these designs. The present study aimed to assess stress distribution patterns in natural tooth and implant supported removable partial denture with different attachment designs...

BACKGROUND Chronic stress affects many Americans. Stress management programs may be prohibitively expensive or have limited access. PURPOSE This study aims to determine feasibility of an 8-week Internet-based stress management program (ISM) based on mindfulness principles in reducing stress in a 12-week, parallel, randomized, controlled trial. METHODS Participants were randomly allocated to...

The paper illustrates the research on post-traumatic disorders conducted in Kraków at the Department of Psychotherapy and the Department of Psychiatry of the Jagiellonian University Medical College after 1989. The political changes that occurred in Poland after 1989 allowed the research to be extended with new groups of survivors. Having conducted the research of the former concentration camp p...
