Causal Relation of Psychical Stress to Acute Back Pain
Acta chirurgiae orthopaedicae et traumatologiae Cechoslovaca, 2018PURPOSE OF THE STUDY There s a known relation between the chronical back-pain-syndrome and psychical problems. We suppose a direct causality between acute stress and onset of the backpain syndrome. MATERIAL AND METHODS A prospective cohort-study (IV/2014 - VIII/2014) of patients who came to our emergency department with acute backpain-syndrome, with no

Examination of Stresses in Sleeve Bearing Backs
SAE Technical Paper Series, 1981<div class="htmlview paragraph">The foundation of any multi-layered sleeve bearing is its backing. Traditional analytical methods cannot account for the variation in design, manufacturing techniques, or assembly practices--all of which have a decided affect on bearing performance.

Attributions, Stress, and Work-Related Low Back Pain
Applied Occupational and Environmental Hygiene, 2002Occupational low back pain (LBP) is a major cause of morbidity and cost. Efforts to control LBP are largely unsuccessful, and better understanding of risks is needed, especially psychological factors. The purpose of this research was to assess the association between worker attributions and LBP.

Friction stress and back stress in cyclically deformed Ni3Ge single crystals
Materials Science and Engineering, 1988Abstract Stress-strain hysteresis loops obtained from cyclic deformation of Ni3Ge single crystals under strain control were analyzed. The major component of the cyclic flow stress was found to be the friction stress. The back stress was responsible for, at most, several per cent of the cyclic flow stress.

Constitutive Equations for the Back Stress in Amorphous Glassy Polymers
Mathematics and Mechanics of Solids, 2005Constitutive equations for the back stress in amorphous glassy polymers based on extended forms of the non-Gaussian James—Guth 3-chain and Arruda—Boyce 8-chain models of rubber elasticity are derived from the extended Wu and van der Giessen non-Gaussian full-network model.

Back-stress influence on minimum stress calculations in hydraulic fracturing experiments
Environmental GeotechnicsThe analysis of fluid injection pressure variation during hydraulic fracturing is widely used for tectonic stress estimation. However, the models used for that are based on several simplifying assumptions. In this article, based on the results of laboratory experiments, we show that it is necessary to consider some additional parameters for a more ...
