The contemporary Formula 1 racing car makes extensive use of advanced composite materials in its construction. The design, manufacture, and ultimate performance under compression of composite suspension push-rods that typically could be used in a Grand Prix racing car are described in this present paper. An aerofoil cross section has been used based on different lay-ups of carbon/epoxy composit...

This study compared the biomechanics of 3 fixation techniques: bilateral pedicle screw (BPS) fixation, unilateral pedicle screw (UPS) fixation, and UPS supplemented with translaminar facet screw (UPS+TLFS) fixation. The study was conducted in an L3-L5 finite element model. Three different finite element models were created by adopting different fixation techniques after removal of the left L3-L...

Background. Regardless of the age, elite athletes exhibit various motor capabilities (e.g., speed; endurance; strength) that are specific to that particular sport. Objectives. The purpose of this study was to compare different aspects of physical fitness (agility, strength, endurance) in thirty, 9 year old elite soccer and hockey players. Methods. Participants completed a 90 minute familiariz...

Presented are 24 non-dimensional buckling curves to estimate the strengths of Fibre-Reinforced Polymer (FRP) square plates having four simply supported edges and subjected in-plane uniaxial uniform compression. The constructed by authors from a parametric numerical analysis using ABAQUS® software with changing variables for: material properties; initial geometrical imperfections; laminate lay-u...

The reference to ethnicity in the 2012 National Suicide Prevention Strategy for England (1) is mainly with regard to promoting mental health in Black and Minority Ethnic (BME) groups. However, there is little detailed information about any specific strategy to reduce suicide rates in BME groups. The Suicide Prevention Strategy and Action Plan for Northern Ireland has only one brief reference re...

In a “follow-up visit”, a patient seeks medical attention for an existing health problem. Using data from the Vietnamese public hospital system, we present a more nuanced analysis of follow-ups in health communication than the one currently available. To be specific, we discriminate between “same follow-ups”, in which the doctor is the same one as in the last visit, and “different follow-ups”, ...

The purpose of this study was to analyze upper extremity and core muscle activation when performing push-ups with different suspension devices. Young fit male university students (n = 29) performed 3 push-ups each with 4 different suspension systems. Push-up speed was controlled using a metronome and testing order was randomized. Average amplitude of the electromyographic root mean square of Tr...
