A continuum damage mechanics (CDM) meso-model was derived for both intraply and interply progressive failure behaviors of a 2D woven-fabric composite laminate under a transversely low velocity impact. An in-plane anisotropic damage constitutive model of a 2D woven composite ply was derived based on CDM within a thermodynamic framework, an elastic constitutive model with damage for the fibre dir...

Pulmonary tumour thrombotic microangiopathy (PTTM) is a rapidly progressive pulmonary disease that is a fatal complication of malignancy. It manifests clinically as subacute respiratory failure with pulmonary hypertension, progressive right sided heart failure, and sudden death. We describe here a case of PTTM associated with occult metastatic signet ring cell carcinoma of the stomach. Although...

Three cases of progressive supranuclear palsy are reported in which In111-DTPA cisternography showed slow diffusion, ventricular reflux and failure of isotope clearance. The clinical diagnosis of progressive supranuclear palsy was confirmed histologically in two of these patients. The possible causes of the cisternographic changes and their relationship to the changes of CSF dynamics in progres...

Progressive damages in the open-hole compression (OHC) tests of composite laminates were experimentally and numerically studied. In experiment, failure mechanisms investigated via situ microscopy observation, digital image correlation, X-ray radiography, computed tomography. Three layups tested to examine dependence progressive on layups. Additionally, numerical simulation was conducted compreh...

INTRODUCTION We report a case of pseudomembranous tracheobronchitis caused by Aspergillus fumigatus 2 years after matched unrelated stem cell transplant. CLINICAL PICTURE The patient presented with dyspnoea and obstructive airway disease coinciding with the onset of chronic graft-versus-host disease (GVHD). Following treatment with higher immunosuppressive therapy for presumptive diagnosis of...
