An experimental study has been conducted to investigate if a new and simple system, that is, stripes of high-bright dynamic green LED lights installed on the floor, can support people way-finding in smoke-filled railway tunnel evacuations. The impact of way-finding installations on people evacuation (intended as people movement paths and evacuation times) has been studied using Oculus Rift, a head

Autoantibodies termed C3-nephritic factor (C3NeF), which stabilize convertases of the alternative complement pathway, often stimulate autoinflammatory diseases. However, knowledge about analogous autoantibodies acting on the classical pathway (C4NeF) is limited to a few reports, which indicate association with kidney dysfunction, systemic lupus erythematous, and infections. C4NeF may appear indepe

Background: Incisional hernia is one of the most common complications after laparotomy. The aim of this retrospective study was to investigate incidence, location and risk factors for incisional hernia after open resection for colorectal liver metastases including the use of perioperative chemotherapy and targeted therapy evaluated by computed tomography. Methods: Patients operated for colorectal

Rivers transport similar to 6 x 10(12) mol yr(-1) of dissolved Si (DSi) from the continents to the oceans. They also carry amorphous silica (ASi), solid phases likely to dissolve in seawater. Unfortunately, the magnitude of this flux is poorly constrained at a global scale. We present 92 new ASi values from suspended particulate matter (SPM) from the Ganges basin. Bulk SPM is 1.2% ASi, and mean AS

The integrity of the white matter is as important as that of the gray matter and white matter pathology has commonly been reported in elderly subjects and in patients with organic dementia. The aim of the present study is to develop and evaluate an improved method for reliable tomographic measurements of absolute white and gray matter blood flow. The new tomographic method (modified Xe-SPECT) is b

In this paper the development of an extension module to the IWA/COST simulation benchmark to include expert reasoning is presented. This module enables the detection of suitable conditions for the development of settling problems of biological origin (filamentous bulking, foaming and rising sludge) when applying activated sludge control strategies to the simulation benchmark. Firstly, a flow diagr

Background: Contact dermatitis resulting from the use of shin pads is usually caused by rubber components, dyes, benzoyl peroxide, or formaldehyde resins. Objectives: To investigate and identify a new allergen in shin pads that was responsible for severe contact dermatitis in a young football player. Methods: High-performance liquid chromatography (HPLC) of samples of shin pads was performed. The

Climate change is an important new challenge for local authorities. This study analyses the potential for using the Swedish mandatory process for risk and vulnerability analysis (RVA) as a vehicle to improve local climate adaptation work. An advantage with RVA is its comprehensive approach in dealing with all relevant threats and all vital functions of society. In order to test the applicability o

Purpose: SCOPA-SLEEP is a rating scale for night-time sleep and daytime sleepiness (DS) proposed for use among people with Parkinson’s disease (PD) as well as others. We translated it into Swedish and assessed its psychometric properties in PD and age-matched healthy controls. Methods: Following translation according to the dual-panel approach, the Swedish SCOPA-SLEEP was field-tested regarding co

Based on an ethnography at the Swedish Public Employment Service, this paper offers a typology of how employees managed to obey tasks they would rather not perform. It is argued that earlier studies of workplace obedience have tended to focus on a single mood in which the actor obeys: despair, cynicism, or seduction. Here, the movement between these moods is analysed. To pass from despair to cynic

In this paper, we examine how one can exploit baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. We propose a multilook approach to counteract the presence of the

The Sound Area, located between Sweden and Denmark, is one of the most intensely trafficked waters in the world with complex traffic patterns and a bridge/tunnel under construction, which will link the two countries. This high level of complexity increases the probability of both maritime accidents and very negative consequences of them. This paper presents the ergonomic part of an ongoing multidi

Artikeln beskriver ett framgångsrikt försök att förändra undervisningssättet i en tillämpad teknikkurs. Resultatet av förändringen är överlag nöjdare studenter samt ett bättre examinationsresultat.

The paper presents a feedback scheduling strategy for multiple control tasks that uses feedback from the plant states to distribute the computing resources optimally among the tasks. Linear-quadratic controllers are analyzed, and expressions relating the expected cost to the sampling period and the plant state are derived and used for on-line sample-rate adjustments. In the case of minimum-varianc

In today’s business environment the use of e-business is gradually becoming more common. This paper sets out to highlight the implications for logistical operations and possible future developments in a vendor-customer relationship (B2B environment) when e-business is introduced. The paper implies that use of an e-business solution does not necessarily mean any changes in the physical distribution
