Objective: The aim of the present study was to characterize the pharyngoesophageal segment in laryngectomees who rated themselves as functional tracheoesophageal speakers. Methods: Voice perceptual assessment, high-resolution videomanometry of swallowing and phonation, and high-speed camera recording during phonation provided information about the anatomy and function of the pharyngoesophageal seg

Oncological therapy resembles a military force that eliminates the central power of a country (dominant clone of a cancer) to create a vacuum where insurgents (subclones) thrive and instigate rebellion (relapse). We suggest that military counterinsurgency doctrine can inspire a discussion of cancer that uniquely embraces both cancer cell evolution and tumour microenvironment.

Background: Dietary thylakoids derived from spinach have beneficial effects on body fat accumulation and blood lipids as demonstrated in humans and rodents. Important mechanisms established include delayed fat digestion in the intestine, without causing steatorrhea, and increased fatty acid oxidation in intestinal cells. The objective of our study was to elucidate if increased fecal fat excretion

South Africa is a mineral-rich country and one area in which minerals can be very important is catalysis. Over an extended period of time, homogeneous catalysis has grown to become very useful, particularly in the chemical and pharmaceutical industries. The organometallic compounds required in the catalysis industry have advanced from metallocenes to an alternative in the form of α-diimines. Most

The Mesozoic biotas of Scandinavia have been studied for nearly two centuries. However, the last 15 years have witnessed an explosive advance in research, most notably on the richly fossiliferous Triassic (Olenekian-Carnian) and Jurassic (Tithonian) Lagerstätten of the Norwegian Arctic Svalbard archipelago, Late Cretaceous (Campanian) Kristianstad Basin and Vomb Trough of Skåne in southern Sweden,

In modern business, standards are too important to be ignored. But what is the rationale for active engagement in long and costly standardization processes when most of those standards will be openly available for a much lower price once they are finalized? What are the strategic motives for engaging in such processes? And even when the motives are clear, how is corporate standardization managed,

The magnet design of the MAX IV 3 GeV storage ring replaces the conventional support girder + discrete magnets scheme of previous third-generation synchrotron radiation light sources with a compact (Ø25 mm aperture) integrated design having several consecutive magnet elements precision-machined out of a common solid iron block. The production series of 140 integrated magnet block units, which was

In the Fall of 1977, The Institute of Economics at the University of Lund arranged a symposium on the theoretical contributions of Knut Wicksell and the subsequent development of his ideas by other theorists. The symposium was financed by the Arne Ryde Foundation. The aim of the symposium was to examine the effects of Wicksell's ideas on the development of economic theory and to discuss the assert

Volymen lyfter fram några aspekter av hur kyrkoåret har uppfattats, främjats och reviderats under det senaste seklet. Artiklarna belyser kyrkoårets gestaltning i predikoutkast, evangeliebok, folklig sed, sång, musik och liturgiska textilier. Dessutom finns en fyllig recensionsavdelning.

The Taghdout Group is a passive margin sequence deposited during rifting and break-up of the northern margin of the West African craton (WAC), culminating with the creation of an oceanic basin between the northern edge of the WAC and an unknown terrane. However, the age of this passive margin has been poorly constrained. It was previously thought to be c. 800–1000 Ma on the basis of age of the con
