Popular Abstract in Swedish Ozonförtunning och UV-B strålning Livet på jorden är beroende av ozonlagret, som finns i ett område 10-50 km upp i atmosfären som kallas stratosfären. Ozonmolekylerna (O3) absorberar bland annat ultraviolettstrålning-B (UV-B), som är en osynlig och skadlig komponent i solljuset. De senaste tjugo åren har ozonlagret tunnats ut därför att ozonförstörande ämnen, t.ex. freLevels of ultraviolet-B (UV-B, 280-320 nm) radiation reaching the Earth´s surface increase due to stratospheric ozone depletion. In this thesis the effect of enhanced UV-B radiation was studied on the atrazine-tolerant mutant Stallion, susceptible to photoinhibition, and the atrazine-sensitive cultivar Paroll of Brassica napus (oilseed rape). Photosynthetic parameters were studied with chlorophyll

HAVERIER i social barnavård är lyckligtvis mycket ovanliga. I detta arbete analyseras fem fall som alla vid någon tidpunkt har utvecklats på ett olyckligt sätt. De olika fallen ger tillsammans en bred belysning av dilemmor och möjligheter i socialt och psykiatriskt arbete med utsatta barn. Genom att analysera olika vändpunkter i fallen diskuteras både haverier och god praktik. Läsaren kan själ

The term ‘strategic use of procurement’ indicates that the procurement (also referred to as sustainable procurement) is about more than just saving money. Other important interests such as social and environmental considerations can be promoted through public procurement. Procurers can, according to newly proposed Directives on public procurement, make better use of public procurement in support o

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

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

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

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

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

It is shown that under certain regularity conditions on the norm, the functions in a nontrivial invariant subspace of the backward shift operator have meromorphic pseudocontinuations in the Nevanlinna class of the exterior of the unit disk. In addition, we provide a regularity condition which implies that the subspace itself is contained in the Nevanlinna class of the disc.
