Of 570 patients operated on for hyperparathyroidism, 18 subsequently died (between one day and 12 yr after operation). Pathological findings at necropsy in these patients have been reviewed. Four necropsies on patients with untreated hyperparathyroidism have also been reviewed for comparison. Of these 22 cases, 14 had renal failure at the time of death. This was attributed to the following: nep...

This work focuses on an experimental and numerical investigation into monitoring damage in a cube-shaped concrete specimen under compression. Experimental uses acoustic emission (AE) signals acquired by two independent measurement apparatuses, the same process is numerically simulated with lattice discrete element method (LDEM). The results from experiment simulation are then compared terms of ...

In this paper, two-dimensional (2D) orthotropic augmented finite element method (A-FEM) is applied to account for progressive failure of composite laminates under transverse loading, which considers all major cracking modes (delamination, fiber kinking/rupture matrix cracking). High-fidelity simulations different stacking loading are implemented. Both predicted load−deflection curves and damage...

A clinicopathological report is presented of a British male, aged 59 years, who died after an illness of 10 years, manifested by progressive respiratory failure, ptosis, and dysphagia. At no time was there evidence of ophthalmoplegia, Parkinsonism or dementia. At necropsy the main finding was of neurofibrillary tangles in the neurons of the pontine and medullary reticular formation, with partic...

Progressive visual failure as the presenting feature of multiple sclerosis is described in five patients. The clinical features did not permit a distinction from visual loss due to compression. The finding of oligoclonal bands in the CSF at presentation is a useful pointer to the diagnosis, but is not specific and full investigation to exclude treatable causes of visual loss is essential.

Railways are one of the largest transportation networks in world. One key subgrade problems railway track is associated with progressive shear failure (PSF). To-date, limited number studies have addressed mechanism PSF, especially extending mechanics unsaturated soils. In this paper, PSF studied aid computer program that was developed using a Visual Basic AutoCAD, Mohr-Coulomb criteria within s...
