This manuscript investigates compression after impact failure in woven fiber-reinforced composites. Compression failure of composite structures previously damaged by an impact event is due to the propagation of impact-induced damage mechanisms such as interlaminar debonding, constituent (i.e., matrix and fiber) microcracking, sublaminate buckling, as well(More)
We report an unusual case of a giant colonic mucocele following ileo-sigmoid bypass surgery in a patient with advanced adenocarcinoma of the splenic flexure. The formation of a giant colonic mucocele resulted from distal splenic flexure obstruction due to tumour relapse and proximal caecal obstruction due to peritoneal disease with subsequent accumulation(More)
Gastro-Oesophageal Reflux (GOR) is a key problem in Cystic Fibrosis (CF), but the relationship between lung and gastric microbiomes is not well understood. We hypothesised that CF gastric and lung microbiomes are related. Gastric and sputum cultures were obtained from fifteen CF patients receiving percutaneous endoscopic gastrostomy feeding. Non-CF gastric(More)
OBJECTIVES To establish if emergency medicine and neuroscience specialist consultants have different risk tolerances for investigation of suspected spontaneous subarachnoid haemorrhage (SAH), and to establish if their risk-benefit appraisals concur with current guidelines. SETTING 4 major neuroscience centres in London. PARTICIPANTS 58 consultants in(More)
Road safety is a huge concern due to the large number of fatalities and injuries caused by road accidents. Research has shown that fatigue can adversely affect driving performance and increase risk of road accidents. It has been shown that driving performance is enhanced by stress-relieving music which thereby promotes safer driving. Context-aware music(More)
This manuscript presents a computational investigation of the compression-after-impact (CAI) response of polymer matrix composites subjected to seawater induced environmental degradation. A multiscale computational model that accounts for seawater-induced property degradation in composite constituents is proposed to predict the CAI response of E-glass(More)
