This thesis investigates the financial viability of green hydrogen production for mobility applications across four European countries: Germany, Norway, Denmark and Spain. Given the rising importance of hydrogen in hard-to-electrify sectors such as (heavy-duty) transport, the study focuses on understanding how system design and local energy conditions influence the Levelised Cost of Hydrogen (LCOH
The global adoption of International Financial Reporting Standards (IFRS), developed by the International Accounting Standards Board (IASB), aims to enhance financial reporting transparency, comparability, and reliability by standardizing accounting practices and limiting managerial discretion. While IFRS has improved accounting quality in many regions, its impact depends on prior local GAAP quali
Phosphonated polymers may show high intrinsic proton conductivities at low water contents provided that the local concentration of phosphonic acid groups is very high [1,2]. Moreover, the lower acidity of aryl- and alkylphosphonic acids in relation to sulfonic acids requires higher acid contents to reach high conductivities also at higher water contents. In this context, poly(vinylphosphonic acid)
In this paper, the critical factors behind commercialization of new product development (NPD) are investigated in order to add to our understanding of what drives and hampers the commercialization of new products and services. With the illustration of nine cases of commercialization from three multinational organizations, an initial framework of three categories of factors related to the success o
This study examined the molecular mechanisms of neutrophil migration to sites of mucosal bacterial infection. (1) Bacterial induction of neutrophil chemotactic cytokines and their role in neutrophil migration. Uropathogenic E.coli were shown to stimulate urinary tract epithelial cells to produce a specific array of cytokines including the neutrophil chemoattractant IL-8. IL-8 production was depen
Abstract in FrenchRésumé : Direkt Profil est un analyseur automatique de textes écrits en français comme langue étrangère. Son but est de produire une évaluation du stade de langue des élèves sous la forme d’un profil d’apprenant. Direkt Profil réalise une analyse des phrases fondée sur desitinéraires d’acquisition, i.e. des phénomènes syntaxiques locaux liés à un développement dans l’apprentissag
Upregulation of endothelin B (ETB) and 5-hydroxytryptamine 1B (5-HT1B) receptors via transcription has been found after experimental subarachnoid hemorrhage (SAH), and this is associated with enhanced phosphorylation of the mitogen-activated protein kinase ( MAPK) extracellular signal-regulated kinase ( ERK1/2). In the present study, we hypothesized that inhibition of ERK1/2 alters the ETB and 5-H
In this work, a method for registration of whole-body (WB) scintillation-camera images is presented. The primary motive for the development is to perform activity quantification using the conjugate view method on an image basis. Accurate image registration is required for sequential anterior and posterior scans, for serial emission images for analysis of the biokinetics, and for transmission and e
Popular Abstract in Swedish Målet med kollektivtrafik är bl a att anordna transportförsörjning för alla samhällsgrupper på ett samhällsekonomiskt effektivt vis. En grupp medborgare är rullstolsburna resenärer, vars speciella förutsättningar ställer särskilda krav på transportsystemets utformning. För att utröna dessa speciella förutsättningar på ett ansvarsfullt sätt, är det viktigt att man anläggEliciting wheelchair-seated passengers’ perspective of safety and comfort is both useful and mandatory, particularly for researchers, clinicians, transit authorities, and for operators during purchase and use of vehicle technologies in existing and planned future transport systems. Therefore, the overarching objective of this thesis was to delineate the question of safety and comfort as perceived
A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for cervical cancer is based on data from 1 meta-analysis and 34 randomize
BACKGROUND: Degranulation of eosinophils in target tissues is considered a key pathogenic event in major chronic eosinophilic diseases. However, because of a lack of appropriate methods, little is known about degranulation of eosinophils in common eosinophilic diseases. METHODS: Using transmission electron microscopic (TEM) analysis, a novel approach has been devised and validated to quantify eosi
Objective: To conduct a cost-effectiveness study of nasal budesonide versus surgical treatment in the management of nasal polyps. Design and methods: A decision-tree model reflecting two different treatment strategies for nasal polyps in Sweden was developed. The first strategy was initial polypectomy, performed under three different sets of circumstances: inpatient functional endoscopic surgery,
Aim To identify clinical, immunological and biochemical factors that predict remission, and its duration in a large cohort of young adults with Type 1 diabetes mellitus (DM). Methods In Sweden 362 patients (15-34 years) classified as Type 1 DM were,, included in a prospective, nation-wide population-based study. All patients were followed at local hospitals for examination of HbA(1c) and insulin d
Background: Official guidelines that promote evidence-based and cost-effective prescribing are of main relevance for obvious reasons. However, to what extent these guidelines are followed and their conditioning factors at different levels of the health care system are still insufficiently known. In January 2004, a decentralized drug budget was implemented in the county of Scania, Sweden. Focusing
Background The study was designed to evaluate the analgesic effect and possible adverse effects of acupuncture for pelvic and low-back pain during the last trimester of pregnancy. Methods Following individual informed consent, 72 pregnant women reporting pelvic or low-back pain were randomized during pregnancy weeks 24-37 to an acupuncture group (n = 37) or to a control group (n = 35) at three mat
Background: Ischaemia and local protease activation close to the pancreaticojejunal anastomosis (PJA) are potential mechanisms of postoperative pancreatic fistula (POPF) formation. To provide information on the pathophysiology of POPF, intraperitoneal microdialysis was used to monitor metabolic changes and protease activation close to the PJA after pancreaticoduodenectomy (PD). Methods: In patient
The future evolution of global ice sheets under anthropogenic greenhouse forcing and its impact on the climate system, including the regional climate of the ice sheets, are investigated with a comprehensive earth system model consisting of a coupled Atmosphere-Ocean General Circulation Model, a dynamic vegetation model and an ice sheet model. The simulated control climate is realistic enough to pe
The present study aimed to investigate how the impact of several factors linked to geography would shape life-history traits in a gregarious species, using the pine processionary moth (PPM) Thaumetopoea pityocampa as a model system. PPM has a wide geographical distribution over the Mediterranean Basin, and it is a strictly gregarious species throughout larval development, where the total reproduct
Abstract in Undetermined Although ancient DNA from sediments (sedaDNA) has been used to investigate past ecosystems, the approach has never been directly compared with the traditional methods of pollen and macrofossil analysis. We conducted a comparative survey of 18 ancient permafrost samples spanning the Late Pleistocene (4612.5 thousand years ago), from the Taymyr Peninsula in northern Siberia.
We have prepared poly(arylene ether sulfone) multiblock copolymers with cationic blocks containing single dioxyphenylene rings functionalized with two, three or four quaternary ammonium (QA) roups in order to investigate the influence of the ionic concentration and distribution on the anionic conductivity.Precursor blocks were prepared by polycondensation of 4,4’-difluorodiphenyl sulfone and eithe
