Popular Abstract in Swedish Polymermembranbränsleceller (PEM) anses vara en mycket lovande teknik inom fordonsindustrin på grund av dess kompakthet i storlek, höga verkningsgrader samt låga arbetstryck och temperaturer. De senaste åren har tekniken varit fokus för en anseenlig mängd forskning. PEM-bränsleceller har den stora fördelen att energiomvandlingseffektiviteten har potential för att vara bThis thesis presents numerical simulations of reacting transport phenomena in polymer electrolyte membrane (PEM) fuel cells. Broadly, the presented work is subdivided into macro and microscale simulations. In macroscale simulations, a unit PEM fuel cell with interdigitated flow field configurations is simulated keeping in mind all the essential transport mechanisms, i.e., transport of species, ion

Popular Abstract in Swedish År 2011 är det exakt 20 år sedan lärarkåren kommunaliserades. Reformen ger fortfarande upphov till diskussioner, inte minst från liberalt håll diskuteras idag lärarprofessionens status och vilka konsekvenser kommunaliseringen har medfört. I Professionens problematik analyseras motiven bakom kommunaliseringen. Historikern Johanna Ringarp visar att reformen var ett led i On 8 December 1989, the Swedish Parliament resolved that the state regulation of teaching positions would be terminated beginning on 1 January 1991. The parliament’s decision came on after fierce debates that took place in both teacher staff rooms and in public in 1989. Almost 20 years later, the reform still gives rise to controversy, and current political debates also touch on the possibility of

Hypoxia, or deficient oxygen levels, is an inherent feature of rapidly expanding tumor tissue. In order to survive in the hostile, hypoxic environment and to restore the supply of oxygen and nutrients tumor cells activate a variety of adaptive mechanisms. Among them, hypoxia-induced angiogenesis, i.e. the formation of tumor blood vessels from pre-existing vasculature, has proved to be of critical

In a recent publication, Feng et al. [Feng et al., Nat. Mater., 2015, 14, 61] reported a very interesting re-entrant solidification behaviour of colloidal particles in an aqueous solution containing polyethylene oxide (PEO). In this system, a crystalline colloidal phase, which is present at low temperatures, melts to a homogeneous fluid upon increasing the temperature. Further raising the temperat

Popular Abstract in Swedish Varje år drabbas i världen ca 3 miljoner individer av cancer i mag-tarmkanalen. Stora skillnader finns i incidens med magsäckscancer och matstrupscancer särskilt vanliga i utvecklingsländer, medan tjock- och ändtarmscancer är en av de vanligaste tumörtyperna i västvärlden. Cancer i mag-tarmkanalen ger ofta diffusa symtom, vilket i många fall leder till att tumörerna uppEsophageal cancer and colorectal cancer represents two major types of gastrointestinal tumors. Though refined surgery and introduction of novel chemotherapeutics have improved outcome, more than 2500 Swedes die from these diseases every year. Novel markers for early diagnosis, prognosis and treatment prediction are therefore needed. This thesis aimed to genetically profile esophageal cancer with c

The thesis aims to explore subjective experiences of everyday occupation, social interaction and the view of the worker role among people with psychiatric disabilities(PD), while also addressing the importance of day centre attendance. The thesis consists of one qualitative study, exploring which characteristics in everyday occupation provide meaning to people with PD, and three quantitative studi

Popular Abstract in Swedish Syftet med denna avhandling är att bidra till vår förståelse för vårdutnyttjande och dess förklaringsfaktorer i utvecklingsländer, speciellt i sub-sahariska Afrika. Detta görs genom att fokusera på sjukvårdsutgifter och dess förklaringsfaktorer, samt valet att söka vård för att bota åkomman. Datamaterialete som används kommer från en hushållsundersökning från 1998 omfatThe aim of this thesis is to contribute to our understanding of health care utilisation and its determinants in developing countries, especially in sub-Saharan Africa. This is done by explicitly focusing on health care expenditures and its determinants as well as the choice to seek health care to cure the illness. Firstly, the focus is on a household’s expenditures for health care. The aim of this

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the s

Alla företag, stater, myndigheter och organisationer är i behov av att kunna locka till sig extra kapital till att användas för att finansiera olika verksamheter. Det finns ett flertal olika metoder för detta ändamål såsom banklån, obligationslån, strukturerade produkter, eller utgivning av nya aktier. Uppsättningen av finansieringsmetoder som används av ett företag kallas företagets kapitalstruAll companies, governments, states and organisations need to raise additional finance for different purposes. There are several different methods, such as bank loans, bonds, notes, structured products or new equity, available to obtain the required amount of money. The set of financial sources used by a corporate entity is called the company´s capital structure. Commonly, a company uses a number

Värdeöverföringar av olika slag från ett aktiebolag kan innebära risker för såväl bolagets borgenärer som enskilda aktieägare. Borgenärerna exponeras för en större risk ju mindre kapital som finns kvar i bolaget till betalning av deras fordringar. Minoritetsägare riskerar att bli förfördelade när majoritetsägare driver igenom värdeöverföringar som gynnar dem själva. Värdeöverföringsförbudet i 17 kValue transfers from a company may impose a substantial risk on both creditors and certain shareholders. As the coverage of the share capital decreases and less capital is kept within the company for the payment of its debts, the creditors are exposed to a greater financial risk. The minority shareholders on their part run the risk of being subjected to an undue disadvantage in the decision-making

Our purpose has been to review and analyse the representation of rape, as well as discussions concerning rehabilitation, present in texts targeted at professionals and/or female victims of rape. We wish to investigate whether female victims of rape themselves are given the opportunity of individual positioning with regard to the crimes they have been exposed to. We consider it to be of relevance t

Corporate responsibilities with regard to human rights have long time been in the grey zone, but the area of human rights for businesses has been expanding rapidly. International instruments for corporate human rights responsibilities have been followed by voluntary initiatives, certification schemes, national standards and laws, and other tools and instruments. Analyzing the existing soft law one

OBJECTIVES: Venous thromboembolism (VTE) is a common worldwide disease. The burden of multimorbidity, that is, two or more chronic diseases, has increased. Whether multimorbidity is associated with VTE risk remains to be studied. Our aim was to determine any association between multimorbidity and VTE and any possible shared familial susceptibility.DESIGN: A nationwide extended cross-sectional hypo

The ability for groups to engage in collective action depends on a variety of factors, ranging from social organization to resources to political opportunities amongst others. Yet, on a much more basic level, collective action is dependent on the ability of individuals to come together to interact and coordinate action, or in other words, to create a collective. Individuals must have spaces in whi

Introduction: Treatment options for peritoneal metastases (PM) from colorectal cancer (CRC) have increased, their efficiency should be monitored. For this purpose, register-based data on PM can be used, if valid. Purpose: We aimed to evaluate the completeness and positive predictive value (PPV) of synchronous peritoneal metastases (S-PM) registered among CRC patients in the Danish National Patient

The overall aim of this thesis was to increase knowledge about physiotherapy treatment for infants with lower respiratory tract infections, which is the most common reason for infant hospitalisation worldwide. Physiotherapy treatment for these infants is debated, and there is no clear consensus regarding the best treatment strategy.To examine current treatment and evaluation methods in Sweden, we

BACKGROUND: Short-term geomagnetic disturbances (GMD) driven by the quasi-periodic 11-year cycle of solar activity have been linked to a broad range of adverse health effects, including cardiovascular diseases (CVD) and total deaths. We conducted a large epidemiological study in 263 U.S. cities to assess the effects of GMD on daily deaths of total, CVD, myocardial infarction (MI), and stroke.METHO

Induced polarization (IP) is an acknowledged method in ore exploration and can be applied to evaluate the metal content in dumps containing the residues of ore processing facilities. Existing models explain the relationships between ore content and grain size of the ore particles with IP parameters. However, the models assume full water saturation of the ore containing samples, which is often not

In the past few decades, there has been a global trend of international harmonization of accounting standards, with many countries having either partially or completely replaced their national accounting standards with the International Financial Reporting Standards (IFRS). The intended goal is to remove the barriers that hinder investors when comparing accounting information of companies from dif
