A novel high-speed tensile test instrument is described, capable of measuring the mechanical response of elastomers at strain rates ranging from 10 to 1600 s(-1) for strains through failure. The device employs a drop weight that engages levers to stretch a sample on a horizontal track. To improve dynamic equilibrium, a common problem in high speed testing, equal and opposite loading was applied...

This paper focuses on the mathematical modelling required to support the development of new primary standard systems for traceable calibration of dynamic pressure sensors. We address two fundamentally different approaches to realising primary standards, specifically the shock tube method and the drop-weight method. Focusing on the shock tube method, the paper presents first results of system id...

Macroscopic structure of paper influences how paper behaves in many ways. In this research, the relationship between macroscopic paper structure and water absorption behavior was investigated. The structure of the handsheets made from commercial hardwood pulp was modified by varying basis weight, beating levels and wet press levels. The structural properties as well as the water absorption prop...

This paper reports on a comprehensive investigation of gyroid lattice structures subject to impact loading. AlSi10Mg samples were manufactured using selective laser melting (SLM) and mechanically characterized Digital Image Correlation (DIC). Universal testing machines, drop weight rig, split pressure Hopkinson bar used characterize the aluminium alloy at strain rates ranging from, ??=10?3s?1 u...

we present a case of epitheloid sarcoma that was referred with a 2×3cm ulcerated lesion on the right ankle and edema of the lower leg. foot drop of the right side was present that had caused walking difficulty. after a few months, he developed several sporthricoidal nodular lesions on the medial aspect of right thigh, inguinal lymphadenopathy, weight loss, anorexia and respiratory symptoms. che...

BACKGROUND There is a lack of research about the experiences of participating in weight-reducing interventions. The aim of this study was to explore barriers and facilitators to weight-loss experienced by participants in a diet intervention for middle-aged to older women in the general population in Northern Sweden. METHOD In the intervention the women were randomised to eat either a Palaeoli...

BACKGROUND In previous pilot studies we have demonstrated that the Treatment Motivation and Readiness Test (TRE-MORE) is capable of predicting the outcome of obesity therapy and that a higher muscle mass (MM) is associated with a greater weight loss. Purposes of the present study were: to confirm the predictive value of TRE-MORE scores and MM, using a standardized non-pharmacologic intervention...
