A postintubation tracheoesophageal fistula (TEF) complicated with subglottic laryngotracheal stenosis (SLTS) is a challenge to surgical repair. Laryngotracheal resection and primary reconstruction could result in treatment failure. In this report, we describe the successful management of two cases of postintubation TEF complicated with SLTS using a Montgomery T-tube because of the patients' con...

1. Our objective was to investigate the associations between benthic macroinvertebrate communities and environmental factors described at three spatial scales: local, reach and catchment. Differences in these associations, because of local topography, were determined by categorising sites into those having a large or small ‘reach contributing area’ (RCA), which is the lateral area of land contr...

Definition The deviation of the height of the ocean surface from the geoid is known as the ocean surface topography. The geoid is a surface on which the Earth’s gravity field is uniform. The ocean surface topography is caused by ocean waves, tides, currents, and the loading of atmospheric pressure. The main application of ocean surface topography is for the determination of large-scale ocean ci...

Numerical model simulations of idealized and observed flows are used to investigate the dynamics of low-level jet streams that form in stratified flow downstream of the vertex of large elliptical barriers such as the southern tip of Greenland, hereafter referred to as ‘‘tip jets’’. The tip jet dynamics are governed by conservation of Bernouli function as parcels accelerate down the pressure gra...

The triggering of convective orographic rainbands by small-scale topographic features is investigated through observations of a banded precipitation event over the Oregon Coastal Range and simulations using a cloud-resolving numerical model. A quasi-idealized simulation of the observed event reproduces the bands in the radar observations, indicating the model’s ability to capture the physics of...

Techniques developed for synchronic text classification problems are applied to a significantly diachronic dataset. The scale of the temporal categories appears to matter. The problem addressed is that of using automated text classification methods to temporally locate The Donation of Constantine. The results reported do not contradict the analysis of Lorenzo Valla from 1440, claiming the docum...
