This report describes the results obtained from fire tests in a 1/3-scale room. The aim of the study was to investigate how changes in external radiation and oxygen supply affect the production of smoke and toxic gases. The ventilation was varied to simulate under- and well-ventilated fires. The thermal exposure to the materials was varied to simulate fires of different sizes. Fifty-nine tests wer

It has recently been demonstrated that superparamagnetic iron oxide nanoparticles can be used as magnetomotive ultrasound contrast agents. A time-varying external magnetic field acts to move the particles and, thus, the nanoparticle-laden tissue. However, the difficulty of distinguishing this magnetomotive motion from undesired movement induced in regions without nanoparticles or other motion arti

Introduction: A new grading of exercise capacity during bicycle stress testing has been proposed in Sweden based on the new reference material (‘the Kalmar material’), which has not been validated. We aimed to examine the prognostic information of the new grading of exercise capacity during exercise stress testing. Methods: Data on all bicycle exercise tests performed at the Department of Clinical

Noroviruses (formerly Norwalk-like viruses) are a major cause of acute gastroenteritis worldwide and are associated with a significant number of nosocomial and food-borne outbreaks. In this study we show that the human secretor FUT2 gene, which codes for an alpha(1,2)-fucosyltransferase synthesizing the H-type 1 antigen in saliva and mucosa, is associated with susceptibility to norovirus infection

Ischemic heart disease is the leading cause of death in high-income parts of the world and is caused mainly by atherosclerosis in the coronary arteries. The rupture of an atherosclerotic plaque with subsequent platelet activation and clot formation can lead to myocardial infarction (MI). Atherosclerosis is a complex process, which involves the accumulation and oxidation of low-density lipoprotein

The sperm chromatin structure assay (SCSA) parameter DNA fragmentation Index (DFI) is a valuable tool for prediction of fertility in vivo. Clinical data show that a DFI above 30% is associated with very low chance for achieving pregnancy by natural conception or by insemination. Already when DFI is above 20% the chance of natural pregnancy is reduced, this despite normal conventional semen paramet

Twenty-nine consecutive cases with a t(8;21)(q22;q22) in the bone marrow (BM) karyotype were retrospectively studied concerning clinical, morphological and cytogenetic data. All had been diagnosed as acute myeloid leukaemia (AML), 27 FAB subtype M2 and two M1, comprising 5% of all cytogenetically analysed AML during 18 yr. Auer rods were the most consistent t(8;21)-associated morphological finding

* The ectomycorrhizal fungus Laccaria bicolor has the largest genome of all fungi yet sequenced. The large genome size is partly a result of an expansion of gene family sizes. Among the largest gene families are protein kinases and RAS small guanosine triphosphatases (GTPases), which are key components of signal transduction pathways. * Comparative genomics and phylogenetic analyses were used to e

An optimization procedure has been established aiming to design an integrated thermal protection system (ITPS) with minimum weight. The objective of this research is to establish the procedure and ensure its effectiveness. A corrugated sandwich panel has been chosen as the optimization problem. The ITPS geometric dimensions are considered as the design variables. The objective function is the mass

The monograph reports a number of studies of a therapist’s speech. It comprises three chapters. The first chapter is a theoretical introduction into the scientific problem of the psychotherapeutic utterance. It reveals some psychological aspects of language issue, explains the concepts of “utterance” and “psychotherapeutic utterance”, and provides an account of the research methods used for studyi

The spectrum of mutations in the von Willebrand factor (VWF) gene in a Swedish type 1 von Willebrand disease (VWD) population was investigated. To gain more knowledge about the dynamics of VWD mutations, the data were analyzed from a population genetics perspective. The VWF gene was resequenced in 54 Swedish patients diagnosed with type 1 VWD. Fifty-five variable sites were located in exons, 10 in

Sales statistics indicate large variations in benzodiazepine consumption between the Scandinavian countries: the current difference between Denmark (highest) and Sweden (lowest) is almost two-fold. There are also large within-country variations: e.g. benzodiazepine sales in the Swedish city of Helsingborg, which is close to Denmark, were at the average Danish level and were the highest in Sweden.

We review the clinical and cytogenetic features of 44 acute lymphoblastic leukemias (ALLs) with t(8;14)(q11;q32), including three from our department and 41 ascertained in the literature, focusing on age and gender distribution, peripheral blood values, immunophenotypic data, survival and additional chromosomal changes. Most patients are children or young adults, with a median age of 10 yr for chi

An area and power efficient high-throughput VLSI implementation of a 4 × 4, 64-QAM soft multiple-input-multiple-output (MIMO) detector, that is suitable for high-order constellation schemes is presented. The proposed MIMO detector utilizes information contained in the discarded paths to improve the bit-error-rate (BER) performance, and then reduces computational complexity using three innovative i

It has been acknowledged that the traditional didactic lecture does not always provide the ideal learning and teaching experience (Bligh, 1998). Over the last ten years, individuals and institutions have been exploring the pedagogical possibilities of providing more active and engaging alternatives. One model in particular has been influential in sparking change. The use of Active Learning Spaces

The way we use computers and mobile phones today requires large amounts of processing of data streams. Examples include digital signal processing for wireless transmission, audio and video coding for recording and watching videos, and noise reduction for the phone calls. These tasks can be performed by stream programs—computer programs that process streams of data. Stream programs can be composed

von Willebrand factor (VWF) is a plasma protein that consists of a series of multimers of which the high-molecular-weight VWF multimers are the most potent in platelet adhesion and aggregation. The propeptide of the VWF (VWFpp) is known to be essential in the process of multimer assembly. Genetic studies were performed in a patient with a phenotype of von Willebrand disease (VWD) characterized by
