OBJECTIVE The authors aimed to develop a mechanical model for delivering controlled impact injuries to an articular cartilage surface, with the ability to control peak contact pressure while maintaining a constant rate of loading across all impact levels. METHODS A pendulum-style impactor with a direct contact interface was fabricated, based on previously published successful models. This imp...

The human hip joint withstands high contact forces during daily activity and is therefore susceptible to injury and structural deterioration over time. Knowledge of muscle-force contributions to hip joint loading may assist in the development of strategies to prevent and manage conditions such as osteoarthritis, femoro-acetabular impingement and fracture. The main aim of this study was to deter...

Many conservative treatments exist for medial knee osteoarthritis (OA) which aims to reduce the external knee adduction moment (EKAM). The objective of this study was to determine the difference between different shoes and lateral wedge insoles on EKAM, knee adduction angular impulse (KAAI), external knee flexion moment, pain, and comfort when walking in individuals with medial knee OA. Seventy...

Due to the special (procedural) nature of the language (verbal communication) ‘knowledge’, the dominant trends in applied linguistics research in the last few decades have been advocating ‘acquisition’ rather than ‘learning’ activities where the main focus in SL & FL education should be on ‘meaning’ while some ‘focus-on-form’ being justified. But the ‘form’ to be ‘focused-on’ is mostly misconce...

Elite speed skaters are exposed to asymmetric lower limb loading consequent the unidirectional turns inherent sport. This presents a unique model study effects of sport-specific on interlimb differences in mechanical muscle function. study, therefore, examined baseline asymmetries multi-directional jump tests elite using cross-sectional design. Thereafter, participants were monitored longitudin...

The paper presents a full-scale blast testing experimental campaign conducted on an energyabsorbing connector comprising thin-walled inversion tubes as kernel elements mounted in façade protective panel. LS-DYNA finite element predictions of the global and local deformation/inversion panel/connectors compared reasonably well with observations. After validation, numerical model was used to analy...

This article addresses the relevant problem of stress–strain behavior compressed reinforced concrete columns under lateral pulse loading. A simplified engineering method analyzing limit value loading P, depending on longitudinal force N acting column, is developed. The proposed involves construction P-N curve that has three portions. Portion 1 describes plastic deformation and rebars part struc...

background: indian tea industry workers are exposed to various exposures at their workplace. objective: to investigate the respiratory health of indian tea industry workers. methods: we administered a respiratory questionnaire to and measured lung function in workers of 34 tea gardens and 46 tea factories. we used correlation matrices to test the association between their respiratory symptoms a...
