The principal aims of this thesis are to define suitable measures for safer pedestrian and cycle crossings on arterial roads, to implement these measures on a large scale and to acquire an insight into their effects on road users' safety, experiences, mobility and the environment, by creating a 30 km/h milieu at the above crossings. Two characteristically different types of measures, physical meas
An improved ELISA method for the detection of Staphylococcal. Enterotoxin B (SEB) in protein A preparations is presented. Fab fragments were obtained by digestion with papain of anti-SEB IgG bound to SEB immobilized on Sepharose 4B. Anti-SEB and peroxidase-labeled Fab fragments from secondary antibodies were successfully used in a modified ELISA of SEB in protein A preparations. SEB-Sepharose was
This paper describes the design, simulation and measurement of a GaN power amplifier suitable for envelope and phase signal combination. The low-frequency envelope signal is used to vary the gate (bias) voltage of the device, resulting in a pulse width modulated drain voltage, while modulation of supply voltage or current is avoided. The test circuit is implemented using a discrete GaN HEMT power
Two alternative Human-Machine-Interface solutions for in-vehicle speed support were evaluated in field trials in Hungary and Spain. Twenty vehicles on both test sites were equipped with two kinds of systems: 1) support via an Active Accelerator Pedal and 2) warning via beep signals and flashing red light when exceeding the speed limit. The test drivers drove one month with each system. Both system
Performance demands put on combustion engines are ever increasing, e.g. demands on emissions and fuel consumption. The increased demands together with new combustion concepts increase the need for feedback engine and combustion control. Mathematical models are considered important in order to implement high performance feedback control, as well as to perform diagnostic functions in vehicles. Vario
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
Popular Abstract in Swedish Kärnan kan ses som en samling nukleoner vilka hålls samman av den starka kraften. Nukleonerna är protoner (p) med laddning +1 och neutroner (n) med laddning 0. Kraften kan beskrivas som ett utbyte av mesoner såsom pioner (pi) vilka förekommer i tre laddningstillstånd pi+, pi- och pi0 (laddning +1, -1 och 0). Inuti kärnan rör sig nukleonerna och utbytesmesonerna vilket gA comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintilla
Exopolysaccharides (EPSs) produced by the lactic acid bacteria (LAB) Lactococcus lactis and Streptococcus thermophilus are important for the rheological behaviour and texture of a variety of fermented food products. Furthermore, EPSs from food-grade LAB have potential as food additives and functional food ingredients with both health and economic benefits. However, the production lev
It is well known that nature offers an abundance of materials and processes that can be adapted in low-tech fashion, to fabricate systems capable of removing pollutants from wastewater. During the last decade, extensive basic and engineering research on such natural treatment systems have led to improvement of the quality of discharged wastewaters. However, the mechanisms of natural treatment and
We present the PalCom Object Notation, a textual data representation format for communication between internet of things which support binary and textual data. The format does not require parsing of user data (or the “payload”) and is thus efficient to use also for large binary values such as digital images, audio and video as well as for short textual values. These can be mixed in the same messag
Phosphopeptides are often detected with low efficiency by MALDI MS analysis of peptide mixtures. In an effort to improve the phosphopeptide ion response in MALDI MS, we investigated the effects of adding low concentrations of organic and inorganic acids during peptide sample preparation in 2,5-dihydroxybenzoic acid (2,5-DHB) matrix. Phosphoric acid in combination with 2,5-DHB matrix significantly
We aim to introduce some new solutions in the studies involving the subjects who are not able to use spoken language, both animals and pre-verbal infants. Although our research focuses in general on the episodic memory introduced by Tulving in 1972, this paper is to present the case of Wistar rats and domestic cats.
BACKGROUND: Acute dyspnea affects a large heterogeneous patient group with high mortality and readmission rates.PURPOSE: To investigate if cardiometabolic biomarkers and clinical characteristics predict readmission and death in patients hospitalized for acute dyspnea.METHODS: 65 dyspnea patients at a general internal medicine ward were followed for six months. The combined endpoint was readmission
Objective: The aim of this study was to analyse the impact of maternal BMI at start of pregnancy and maternal weight gain during pregnancy on the risk of various diseases later in life. Methods: In a population-based cohort from southern Sweden, women with at least one delivery registered in the Swedish Medical Birth Register ten or more years before answering a health questionnaire were identifie
The aim was to perform a local study of risk factors and thrombophilia in mesenteric venous thrombosis (MVT), and to review the literature concerning thrombophilia testing in MVT. Patients hospitalized for surgical or medical treatment of MVT at our center 2000-2015. A systematic review of observational studies was performed. In the local study, the most frequently identified risk factor was Facto
