This study examined the associations among self-efficacy, health locus of control, and psychological distress in 159 elderly Chinese women who had chronic physical illnesses. The present findings did not support the dual health control hypothesis that specifies the balance between internal and external health control beliefs is related to a low level of psychological distress. Correlation resul...

Background. Previous studies have shown that an external versus the internal focus of attention is an effective and efficient method to improve athleteschr('39') performance under anxious conditions. Objectives. The current study aimed to assess the effect of the practice with a distinct focus of attention on the penalty kicking performance of adolescent soccer players with different expertise...

In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...

The aim of the current study was to compare the internal and external attributions of success and failure in a sample including recreational gamblers and non-gamblers. Seventy-seven participants (32 males 44 females, 1 unknown sex), ranging in age from 18 to 72 years, who had all gambled at some time in their life, participated in the current study. The Multidimensional-Multiattributional Causa...

The study examined effects of attentional focus on swim speed in expert swimmers. In previous studies, an external focus directed at the movement effect has been shown to enhance automaticity, relative to an internal focus directed at the body movements (or no particular focus). The swimmers in the present study were given focus instructions related to the arm stroke in crawl swimming. All part...

PURPOSE To compare the removal of torque values of machined implant abutment connections (internal and external) with and without soft tissue entrapment using an in vitro model. MATERIALS AND METHODS Thirty external- and 30 internal-connection implants were embedded in urethane dimethacrylate. Porcine tissue was prepared and measured to thicknesses of 0.5 and 1.0 mm. Six groups (n = 10) were ...

The objective of this study was to describe how tibiofemoral internal/external rotation varies in patients after total knee arthroplasty (TKA) when compared with control participants during a sit-to-stand (STS) maneuver. Motion analysis was used to measure internal/external knee rotation during STS in the control and TKA groups. Fourteen participants were included in the study. Six patients wit...

the effective parameters of (5, 0) and (5, 5) single-wall carbon nanotubes during the interaction with carbon dioxide as sensors are determined. the interaction of carbon dioxide  molecules with internal and external walls of the nanotubes is studied using gaussian 03 coding by density functional theory (dft) at the b3lyp/6-311g level of theory. co2 rotation around tube axles vertically and par...
