Although studies on RC beams under shear have a history record of more than 100 years, many important issues in this context still remain that have evaded attention. The aim of the current study is to study a number of these less investigated aspects of the behavior of RC beams under shear. For this purpose, and based on the modified compression field theory, a computer program has been writte...

Background Strong evidence in favour of an ischaemia-guided approach to coronary revascularisation for PCI has led to a huge increase in demand for ischaemia imaging. In our General Hospital setting we have seen a 300% increase in demand for stress MRI over 3 years to more than 800 examinations per year. We therefore sought to optimise patient throughput by process mapping and by the introducti...

We aimed to determine whether an early prophylactic INSURE strategy combined with early nasal continuous positive airway pressure (nCPAP) treatment could decrease the subsequent need for mechanical ventilation (MV) compared to the administration of surfactant prophylaxis later, at the 15th minute after birth, combined with early nCPAP. Infants born at <30 weeks' gestation were randomized to rec...
