The PEFC has emerged as the most viable fuel cell type for automotive and some portable applications, and also has potential back-up power unit applications due to its low operating temperature, comparative simplicity of construction, high power density, and ease of operation. In spite of tremendous scientific advances, as well as engineering progress over the last few decades, the commercializati

Floran i den sydvästligaste delen av Västaustralien är idag internationellt utmärkt somen Biodiversity Hotspot, dvs. ett område som måste bevaras för omvärlden på grundav sin unika artrikedom och höga andel endemiska arter.

In a spatial simulation we show that formation of a stable, narrow hybrid zone requires no selection, only that individuals can recognize their own population type since this is a prerequisite for assortative mating. The European crow occurs in two species/subspecies that meet in a long hybrid zone, the black carrion crow Corvus corone and the grey and black hooded crow C. cornix. In a previous st

To reduce the congestion due to the future bandwidth- hungry applications in domains such as Health care, Internet of Things (IoT), etc., we study the benefit of introducing additional Data Centers (DCs) closer to the network edge for the optimal application placement. Our study shows that the edge layer DCs in a Mobile Edge Network (MEN) infrastructure is cost beneficial for the bandwidth-hungry

We present a study of the performance degradation of electromagnetic absorbers when applied to doubly curved surfaces. The scattering from a perfectly conducting sphere coated with different types of single- and multilayer absorbers has been evaluated using analytic recursion expressions. A comparison of the effect of curvature on the absorber performance is presented for structures based on homog

Den historiedidaktiska processen kring hur en konflikt på en möbelfabrik används ur ett historiebruksperspektiv samt hur historiemedvetande påverkar historiebruket.

Background The familial risks of heart failure (HF) remain largely undetermined. This nationwide follow-up study aimed at determining risk of hospitalization for HF conferred by affected siblings. Methods and results Swedish Multi-generation Register data, with records of at least one full sibling available at start of follow-up, were linked to the Hospital Discharge Register data for 1987–2010. T

Multicolor flow cytometry (MFC) and real-time quantitative PCR (RQ-PCR) are important independent techniques to determine minimal residual disease (MRD) in acute myeloid leukemia (AML). MFC is the standard method, but may be unreliable. Therefore, MFC-based determination of MRD with an RQ-PCR-based approach targeting the nucleophosmin 1 (NPM1) type A mutation was set out to compare. Since most cur

A self-report instrument assessing work-related factors among people with psychiatric disabilities would be useful when trying to match possible employment or prevocational opportunities with people’s desires and capacities. The aim of this study was to explore the factor structure, internal consistency, and construct and criterion validity of the Worker Role Self-Assessment (WRS) in this group as

The adult brain has a very limited capacity for generation of new neurons, and neurogenesis only takes place in restricted regions. Some evidence for neurogenesis after injury has been reported, but few, if any, neurons are replaced after brain injury or degeneration, and the permanent loss of neurons leads to long-term disability and loss of brain function. For decades, researchers have been deve

Succinic acid production from the monosaccharides xylose, arabinose, glucose, mannose and galactose was studied using the bacterium Actinobacillus succinogenes. In Duran bottle cultures, containing 10 g/L of each of sugar, succinic acid was produced from all sugars except for galactose. The highest succinate yield, 0.56 g/g, was obtained with glucose, whereas the succinate yield was 0.42, 0.38 and

This study focuses on the development of unstructured models, including both substrate and product inhibition, that predict the cultivation of Actinobacillus succinogenes and Basfia succiniciproducens on a mixture of C5 and C6 sugars, similar to the sugar composition contained in spent sulphite liquor, the liquid waste stream from the sulphite pulping process. The main sugar monomer contained in t

Brain imaging is essential for the diagnosis and characterization of cerebral small vessel disease. Several magnetic resonance imaging markers have therefore emerged, providing new information on the diagnosis, progression, and mechanisms of small vessel disease. Yet, the reproducibility of these small vessel disease markers has received little attention despite being widely used in cross-sectiona

Background: In implementing new programs of care, such as person-centered care, there is a risk that the focus will be at an organizational level, instead of a level that describes what happens in the personal development among staff. The aim of this study was to describe experiences of the implementation process of a learning supporting model designed to increase patient involvement and autonomy

En sammanställning och genomgång av alla de arkeologiska undersökningar och iakttagelser som gjorts i och vid klostret fram till 2005. I rapporten diskuteras och belyses även ett flertal viktiga frågor, såsom tidpunkt för och orsak till klostrets överflyttning från Vä till Bäckaskog.

Survival rates of childhood cancer have improved markedly, and today more than 80 % of those diagnosed with a pediatric malignancy will become 5-year survivors. Nevertheless, survivors exposed to cranial radiotherapy (CRT) are at particularly high risk for long-term morbidity, such as endocrine insufficiencies, metabolic complications, and cardiovascular morbidity. Deficiencies of one or more ante

Purpose: The aim of this study is to provide evidence on the costs and health effects of two alternative hearing aid delivery models, a community-based and a centre-based approach. The study is set in Bangladesh and the study population is children between 12 and 18 years old. Methods: Data on resource use by participants and their caregivers were collected by a household survey. Follow-up data we

Purpose: The aim of this study was to assess the performance-based visual ability among independently living elderly subjects and to investigate whether there was any association between visual ability and falls. Subjects and methods: A total of 298 randomly selected subjects aged 70-85 years were invited for an examination including monocular and binocular visual acuity (VA), contrast sensitivity
