Background: Today, practically all computed tomography (CT) systems are delivered with automatic exposure control (AEC) systems operating with tube current modulation in three dimensions. Each of these systems has different specifications and operates somewhat differently. Purpose: To evaluate AEC systems from four different CT scanner manufacturers: General Electric (GE), Philips, Siemens, and To

Psoriasis is a common, chronic disease and in one-third of the patients it begins during the first 2 decades of life. The burdens of psoriasis are many, and some can be assessed with quality of life questionnaires. The aim was to investigate the impact of childhood psoriasis on quality of life in children and their parents and to correlate certain clinical findings with quality of life. Forty-five

The article provides an overview of ongoing research and key characteristics of Cognitive Semiotics, an emerging field dedicated to the transdiciplinary study of meaning, involving above all researchers from semiotics, linguistics, developmental and comparative psychology and philosophy. The combination of the following features distinguishes it from other synthetic approaches: (a) integration of

To characterise geographical distribution and time trends of chronic kidney disease (CKD) mortality in the context of the epidemic of Mesoamerican nephropathy (MeN), likely related to occupational heat stress and other, unknown, factors.

Introduction to a seminar and a book with four articles and also a revised bibliography celebrating Professor Emeritus Erik Cinthio's 90 years birthday in 2011.

An analysis of particle formation (PF) events over a subarctic mire in northern Sweden was performed, based on number size distributions of atmospheric aerosol particles (10-500 nm in diameter) and ions (0.4-40 nm in Tammet diameter). We present classification statistics for PF events from measurements covering the period July 2005- September 2006, with a break over the winter period. The PF event

Context: Pediatric cancer treatment may imply an increased risk of hypogonadism, leading to metabolic disorders and osteoporosis. Such complications are potentially preventable. Objective: The aim of this study was to assess diagnosis- and treatment-dependent risk of hypogonadism in male childhood cancer survivors (CCS). Design: Male CCS who were treated during the period 1970-2002 and who in 2004

Despite rapid development, modern graphics hardware is still much too slow to render photo-realistic images in real time, and it will most likely remain so if we rely only on yearly growth in hardware performance. Therefore, better algorithms are constantly needed in order to advance the field. In the first part of this thesis, we present new algorithms for hardware rasterization. We investigate

There are increasing reports of deaths and serious complications associated with the use of negative pressure wound therapy (NPWT). Bleeding may occur in patients when NPWT is applied to a wound with exposed blood vessels or vascular grafts, possibly due to mechanical deformation and hypoperfusion of the vessel walls. Recent evidence suggests that using a rigid barrier disc to protect underlying t

The language on Swedish rune stones written in the 16 character alphabet (futhark) constitutes a very special fragment of the Swedish of its time (about 800-1100). Because of the ritual character of the inscriptions the language is rather standardized. The greatest variation is in proper names. As has long been noted the typical formula is (in English translation): N raised this stone after M his

The thesis aims at finding means for assessing and improving the requirements engineering (RE) process in order to enhance software product quality and increase the competitive edge of software organisations. Quality can be defined as the ability to satisfy the customers’ expectations. Thus, from an RE perspective, improved quality implies improved requirements elicitation and prioritisation effor
