The present climate emergency demands the construction industry to minimise carbon footprint of concrete buildings. In this paper, potential different optimisation strategies reduce ‘cradle-to-gate’ embodied floors which require levels modifications conventional design and practice were compared. savings possible from parametrically optimising slab depth grade concrete, post-tensioning, conside...
PURPOSE The purpose of this study was to compare the bundle tension curves and resultant knee kinematics between 2 tensioning protocols in anatomic double-bundle anterior cruciate ligament (ACL) reconstruction. METHODS Anatomic double-bundle ACL reconstruction was performed in 7 male cadaveric knees. Each graft was tensioned to 22 N under 2 conditions: (1) both bundles tensioned at 20 degrees...
This paper compares the measured lateral load behavior of a 0.4-scale “hybrid” precast concrete wall test specimen with the behavior of a second precast specimen designed to emulate monolithic cast-in-place reinforced concrete shear walls. Both walls have the same overall geometry and are constructed by placing rectangular wall panels across horizontal joints. The lateral resistance at the join...
BACKGROUND The incidences of tendon injuries in certain sections of human or animal populations such as athletes are high, but every human or animal, regardless of age or level of activity experiences some degree of tendon injury. In spite of the various investigations of injuries and treatment, comprehensive studies dealing with the histological, ultrastructural and biomechanical aspects of he...
It has been shown that 12 weeks of eccentric heavy resistance training can reduce pain in runners suffering from chronic Achilles tendinosis, but the mechanism behind the effectiveness of this treatment is unknown. The present study investigates the local effect of an eccentric training regime on elite soccer players suffering from chronic Achilles tendinosis on the turnover of the peritendinou...
