Copper films of 300 nm thickness deposited by planar magnetron sputtering on glass substrates, for substrate temperatures between 300 and 500 K, and deposition rate of 10 ?s?1. Microstructure of these films was obtained by X-ray diffraction, while the texture mode of diffractometer was used for stress measurement by the sin2? technique. The components of the stress tensor are obtained using mea...

A set of test structures for in situ stress measurement is presented. The test structures were realized by means of surface micromachining, adopting photoresist as sacrificial layer and electroplated gold as structural layer. Initially array of buckling type test structures cantilevers, fixedfixed beams, guckel rings and diamond were used to find out critical buckling beam. Later on rotational ...

OBJECTIVE To evaluate the factor structure and measurement invariance of the Diabetes Stress Questionnaire (DSQ), a measure of diabetes-specific stress, across sex, age (<9th grade vs. ≥9th grade), and glycemic control (optimal vs. suboptimal). METHODS Data from 318 adolescent participants were pooled from four archival data sets and the ongoing Predicting Resiliency in Youth with Type 1 Diab...

Residual stress is that which remains in a body that is stationary and at equilibrium with its surroundings. It can be very detrimental to the performance of a material or the life of a component. Alternatively, beneficial residual stresses can be introduced deliberately. Residual stresses are more difficult to predict than the in-service stresses on which they superimpose. For this reason, it ...

BACKGROUND A new instrument to assess stress scoliosis patients have whilst wearing their brace has been developed. Aim of this study was to test the reliability of this new instrument. METHODS Eight questions are provided focussing on this topic only, including two questions to test the credibility. A max. score of 24 can be achieved (from 0 for most stress to 24 for least stress). We have p...

INTRODUCTION The purpose of this study was to analyze the role of general and occupational stress in the relationship between workaholism (recognized in two ways: as addiction and as behavioral tendency) and the intensity of work-family and family-work conflict. MATERIALS AND METHODS The study included 178 working people. The survey was conducted at three stages - half a year before a holiday...

Gecko adhesion has inspired climbing robots and synthetic adhesive grippers. Distributing loads between patches of adhesive is important for maximum performance in gecko-inspired devices, but it is unknown how the gecko distributes loads over its toes. We report in vivo measurements of stress distributions on gecko toes. The results are significantly non-uniform. Gecko-inspired adhesives are se...

The engineering design of structures using polymers requires a thorough knowledge of the basic principles of stress and strain analysis and measurement. Readers of this book should have a fundamental knowledge of stress and strain from a course in elementary solid mechanics and from an introductory course in materials. Therefore, we do not rigorously derive from first principles all the necessa...
