Temperature limitations of Solid Oxide Fuel Cells (SOFC) in transient single operation and steady-state Hybrid System (HS) operation with Gas Turbines (GT) are presented. For transient SOFC simulations, an unsteady-state SOFC model was developed by upgrading a detailed validated steady-state model. As critical SOFC single operation modes, concerning the risk of material cracking due to exceeding S
Popular Abstract in Swedish Syftet är att dels studera olika ventilationssystems förmåga att tillföra och föra bort luftflöden. Den andra delen av syftet är att studera konstruktionskriterier och energi användning för ett variabelflödessystem baserat på konstanttryckshållning av det statiska trycket på grenkanalnivå och som endast tillför uteluft. Ventilationssystemens luftflöden studeras med hjälOne part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only. To inves
1 The effectiveness of antimuscarinic agents in the treatment of the overactive bladder (OAB) syndrome is thought to arise through blockade of bladder muscarinic receptors located on detrusor smooth muscle cells, as well as on nondetrusor structures. 2 Muscarinic M-3 receptors are primarily responsible for detrusor contraction. Limited evidence exists to suggest that M-2 receptors may have a role
Difficulties in attracting student teachers have resulted in research focusing on student teachers' motives for studying to join the profession. Because previous findings are mixed, the first aim of this study was to explore motives for students to become teachers. A second aim was to explore the relationship between teachers' motives and their academic engagement and dropout rates at the end of t
Dyskinesia and motor fluctuations affect up to 90% of patients with Parkinson's disease (PD) within ten years of L-DOPA pharmacotherapy, and represent a major challenge to a successful clinical management of this disorder. There are currently two main treatment options for these complications, namely, deep brain electrical stimulation or continuous infusion of dopaminergic agents. The latter is ac
PurposeThe aim of this study was to analyse prescription refill, re-hospitalisation, total mortality, mortality because of suicide and attempted suicide among patients who were taking various types of antipsychotics. MethodsA population-based cohort study analysed all patients (n=26046) in Sweden who had been treated for schizophrenia from 2006 to 2009 with regard to re-hospitalisation and prescri
In the paper we present a research model for evaluating determinants of ERP value in small and medium-size enterprises (SMEs). The model is grounded in the diffusion of innovation (DOI) model and resource-based view of the firm (RBV) theory. The research model links six DOI determinants to explain ‘ERP use’ linked with two additional determinants to explain ‘ERP value’, on which nine hypotheses ar
The Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) in 2013–2014 was the most comprehensive analysis of anthropogenic climate change, its impacts, and potential responses. It concluded that climate change is “unequivocal” and human activities are the dominant cause. Avoidance of “dangerous” climate change will require sustained substantial reductions of emissi
AbstractThe uptake of different nitrogen forms by understory species was studied in field and laboratory. Species of the understory in deciduous forests have previously been thought to take up and assimilate only inorganic nitrogen sources. However, species also have the opportunity to assimilate amino acids, usually in low rates compared with ammonium, according to solution culture studies, but m
The Swedish consumer magazine Råd & Rön (”Advice and Results”) has been available to Swedish consumers since 1958. For a major part of this time the Swedish state, represented by Konsumentverket (the Swedish Consumer Agency) and its predecessor, Konsumentinstitutet (the National Institute for Consumer Information), was the owner of the magazine. In 2006 Råd & Rön was sold to the independen
The aminopropyltransferase spermidine synthase (SpdS) is a promising drug target in cancer and in protozoan diseases including malaria. Plasmodium falciparum SpdS (PfSpdS) transfers the aminopropyl group of decarboxylated S-adenosylmethionine (dcAdoMet) to putrescine or to spermidine to form spermidine or spermine, respectively. In an effort to understand why efficient inhibitors of PfSpdS have be
Human pluripotent stem cells provide new choices for sources of A9-type dopaminergic (DA) neurons in clinical trials of neural transplantation for patients with Parkinson's disease (PD). For example, "self" and HLA-matched A9 DA neurons may improve the patient-to-patient variability observed in previous clinical trials using fetal DA neurons and obviate the need for long-term immunosuppression in
Complex formation between Pd(H2O)(4)(2+) and maleic acid (H(2)A) has been studied at 25 degrees C and 2.00 M ionic strength in acidic aqueous solution. Reaction takes place with 1:1 stoichiometry. The kinetics has been followed by use of stopped-flow spectrophotometry under pseudo-first-order conditions with maleic acid in excess. In the concentration ranges 0.01 less than or equal to [H(2)A](tot)
Background Individuals without occupational exposure are exposed to mercury (Hg) from diet and dental amalgam. The kidney is a critical organ, but there is limited information regarding the relationship between Hg in kidney (K-Hg), urine (U-Hg), blood (B-Hg), and plasma (P-Hg). Objectives The aim was to determine the relationship between K-Hg, U-Hg, B-Hg, and P-Hg among environmentally exposed ind
Investigations on exposure to electromagnetic have generated conflicting results both in epidemiological and laboratory studies, leaving their possible health consequences largely inconclusive. One of the well-reported reasons for the discrepancies is that there is no generally accepted theory to describe the interactions between the very weak electromagnetic fields and the living cells. This work
In the last couple of years, a conflict between football supporters and police have occurred. This conflict has resulted in many instances of violence between the two parts and protests from the supporters. Some that have been met with even harder legislation around and during football games in Stockholm. The police are actively trying to make a safer envoierment during the games while the support
This study sought to investigate unaccompanied migrant children’s experiences in different forms of Swedish Social Work. The primary goal of the study was to obtain a general picture of how the children perceived treatment from authority figures in their daily lives. The study was made in the light of current political events in Europe, where migrant children have been both criminalized and victim
