Analysis of Multiphase Transport Phenomena in PEMFCS by Incorporating Microscopic Model for Catalyst Layer Structures

The catalyst layer (CL) in polymer electrolyte membrane (PEM) fuel cells is one of the key components regulating the overall performance of the cell. In PEM fuel cells, there are two CLs having identical composition for hydrogen oxidation (HO) and oxygen reduction (OR) reactions. There are four phases inside the CL, namely: carbon, Pt particles, ionomer and voids. In this work, a micro-model of th

Reconciliation and the Search for a Shared Moral Landscape – An exploration based upon a study of Northern Ireland and South Africa

Popular Abstract in Swedish Denna avhandling fokuserar på frågan om försoning och (sökandet efter) värdegemenskap. Värden sätts in i ett större sammanhang, i ett så kallat "moraliskt landskap". Avhandlingen beskriver först olika hinder för försoning och dialog i Nordirland och Sydafrika i form av följande komponenter av det moraliska landskapet: -Erfarenheter (av trauma, segregation, ojämlikhet) -In Northern Ireland and South Africa obstacles to reconciliation were found in these elements of a “moral landscape”: – Experiences of trauma, separation and inequalities, – Divergent views of the conflict and of “the other”, – Opposing identifications and loyalties, – Norms for interaction, – Contestant interpretations of values such as “peace” and “justice”. This study describes how these obstac

Subjective Indoor Air Quality in Hospitals - The Influence of Building Age, Ventilation Flow, and Personal Factors

Relationships between subjective perception of indoor air quality, building characteristics, indoor exposures, and personal factors were studied in 225 female Swedish hospital workers. The prevalence of weekly complaints to do with dry air was 87% for air dryness, and 36% for static electricity. Such com plaints were more common in new and well ventilated buildings. The sensa tion of air dryness w

Nuns and Sisters in the Nordic Countries after the Reformation. A Female Counter-Culture in Modern Society

Female religious communities, and later also convents, accompanied the return of the Catholic Church to the Nordic countries in the middle of the nineteenth century. These religious communities were mostly so-called active orders or congregations, who helped in parishes or ran private schools, orphanages or nursing homes. In the 1930s there were nearly 1,400 Catholic sisters working in Scandinavia

Experimental Stroke and Neurotrophins: Regulation, function and gene transfer of neurotrophins in rat and mouse models of focal cerebral ischemia

Popular Abstract in Swedish Stroke är den tredje vanligaste dödsorsaken och den vanligaste orsaken till neurologiskt handikapp. Idag är möjligheten att motverka skadeutvecklingen vid stroke begränsad. Experimentella modeller för stroke innebär att vi kan studera mekanismer för nervcellsskada vid patologiskt sänkta blodflödesnivåer (ischemi). I våra studier har mellersta hjärnartären på ena sidan tStroke caused by focal cerebral ischemia is a major cause of death and neurological disability in humans. The forebrain region most commonly affected by ischemic incidents is that supplied by the middle cerebral artery. In this thesis, neuronal cell death has been investigated using immunohistochemistry for identification of specific neurons and unbiased counting methods after transient occlusion

Romantik i välfärdsstaten : metamorfosförfattarna och den svenska samtiden

Efter krigets och ångestens fyrtiotal vände sig den svenska litteraturen mot den ljusa romantiken, heter det i handböckerna. Paul Tenngarts studier av fem svenska författare med rötter i den legendariska Metamorfoskretsen - Paul Andersson, Lasse Söderberg, Svante Foerster, Petter Bergman och Birgitta Stenberg - ger en annan bild, där romantiken är samhällskritisk med udden riktad mot folkhemsbygge
