Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Hearing is considered to be the most important sense for the communication between people. Several studies have shown that hearing loss can lead to deterioration in quality of life, reduced social activities, feelings of alienation and hence the increasing incidence of depression symptoms.An early audiological rehabilitation is a prerequisite for proper communication among people with hearing loss. Knowledge has been shown to be of great importance and structured learning and individually targeted approach can be expected to facilitate the audiological rehabilitation.The purpose of this study was to examine the effect of an educational effort for people with hearing loss where the effort was made in the distance within the audiological rehabilitation and was followed-up by professional phone support, through a randomized controlled study.The study group consisted of 69 hearing aid users who were randomized by an independent person into two groups, an intervention group and a control group. The intervention group (n = 33) had access to the book "When the sounds are weaker - on hearing and hearing aids". The group received weekly topic-based information related to the different chapters of the book, in five rounds.

Denna studie beskriver innebörden i begreppen användbarhet och Activity Theory, samt hur den senare kan användas för att stärka utvecklingen av användbara webbplatser. Studien är genomförd ur ett utvecklarperspektiv. Resultatet av studien visar att användbarhet är en egenskap som uppstår i användandet av en artefakt, detta pekar både teori och empiri på. Studien visar också att Activity Theory kan användas på flera sätt för att stärka utvecklingen av användbara webbplatser. Vi anser att de resultat vi kommit fram till i vår studie gäller inte bara för utveckling av webbplatser utan de gäller även utvecklingen av informationssystem och informationsteknologi i en vidare utsträckning..

The purpose of this master thesis is to describe and analyse the development of the library history in the municipality of Karlsborg. This is done with a comparison to the library development in Sweden as a whole and in particular to the cities of Lidköping and Halmstad. I have worked according to the following questions: 1. How did the libraries develop before the municipality took over? 2.

Title:What influences the assessment of addiction treatment? - Factors that may affect thechoice of interventionsThere are few studies on trauma and the importance of religion for the professional handlingof abuse clients in a Swedish context. It is therefore appropriate to examine the role of suchfactors. This study examines whether experienced trauma in childhood or religious beliefsinfluence the assessment and selection of input in fictitious cases. To examine this created sixvignettes.

Aim Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) is an international survey tool based on parents' estimation of their child's motor coordination skills. The purpose of this study was to investigate the validity of a Swedish version of DCDQ'07 by finding out how the classification of Developmental Coordination Disorder (DCD) via DCDQ'07 is consistent with the classification of DCD via the motor impairment test, Movement ABC.MethodIn the context of a larger study, a Swedish translated version of the parent survey DCDQ'07 were sent to 4000 randomly selected families with children aged 8 - 10 years in Stockholm County. The classifications "DCD" or "NOT DCD" with cut-off values ??of 56 (9 years) and 57 (10 years) were applied. Forty families were selected from 410 registered responses.

Vid konstruktion och tillverkning av motorer idag finns flera krav att tillgodose i form av lång livslängd, låga utsläpp samt liten bränsleförbrukning. Dieselmotorn har högre verkningsgrad än bensinmotorn men problemet med dieselmotorn är i form av utsläpp där lagstiftningen blir allt strängare. En del av utsläppen från dieselmotorn kan bero på smörjoljan och olika motorer och ytor uppvisar olika mängd oljeförbrukning. Denna kan även variera mellan samma modell av motor. Ett sätt att få ner oljeförbrukningen och variationen av denna är att mäta ytan och säkerställa att denna är optimal för dess funktion.

The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.

Genomförda undersökningar visar att formativ bedömning förbättrar elevers inlärning och förståelse. Den svenska läroplanen från 2011 ger tydliga indikationer på att formativ bedömning ska inkluderas i undervisningen. Vår diskussion i denna uppsats är därför aktuell och den visar hur forskare artikulerar fenomenet formativ bedömning. Litteraturstudien inkluderar information om vad formativ bedömning innebär och förslag på hur man kan arbeta utifrån ett sådant arbetssätt. Vår studie visar att de viktigaste komponenterna inom formativ bedömning är att tydliggöra målen, återkoppling samt själv- och kamratbedömning.

Among young adults and especially women, psychological issues are common phenomena in the society such as depression, anxiety and stress. Research has shown that physical activity can be a complement for anti-depressant medication. The aim of this review is to examine previous research to find out how physical activity can provide positive effects on overall mood state in particular young women's psychological health. The results of this review is that there are support in the literature of young women that physical activity may enhance mood in studies of depression and anxiety symptoms and small support for the effects on reducing stress. Physical activity with both high intensity and low intensity has shown to have positive effects on depression and anxiety, but the physical activity has to be regular for long-term effects.

The snow leopard (Panthera uncia) is an elusive felid, native to the mountains in central Asia. Basic knowledge about the snow leopards? ecology has long been lacking but is advancing with the help of the GPS-technology. GPS cluster analysis can provide insight in the diet and prey selection of elusive predators, such as the snow leopard. Acceleration data from GPS collars can be used to study animal behavior but the two have never been combined to gain more detailed information of the feeding behavior of large carnivores.

Background: Overweight and obesity has become an increasing health issue around the world, which leads to an increase of cardiovascular diseases. The reason for this is a lack of physical activity in combination with an overconsumption of unhealthy food. In the primary healthcare is the ordination of physical activity on prescription offered as a treatment, which is an important health preventive action. When clients get physical activity on prescription they are given the opportunity to receive health counseling as a way to motivate a change in an unhealthy way of living.Objectives: This study aim to examine the experience of the health counseling of individuals with overweight related problems, in combination with the prescription of physical activity.Method: Qualitative interviews were chosen as method. Nine individuals participated in the study, seven females and two males, who had been to health counseling at Friskvården in Värmland.

Determination of serum thymidine kinase 1 (TK-1) activity is used as a tumour marker in both human and veterinary medicine. TK-1 is an intracellular enzyme involved in a salvage pathway of DNA synthesis. The expression of TK-1 is cell cycle dependent and the activity increases markedly after the G1 to S transition in the cell cycle and then declines rapidly in G2. The pronounced proliferative activity in tumour cells result in a higher TK-1 enzyme activity within the cell. The fact that the increased TK-1 activity can be measured in serum makes TK-1 a useful marker in diagnostics of neoplastic diseases and it provides information regarding prognosis and treatment effectiveness. In human medicine a radioactive based test is used to determine the TK-1 serum activity.

I detta arbete behandlas transient simulering i ett 1D-simuleringsprogram, i dettafall Gamma technologies GT-Power. Vad som behöver ändras i en modell för attden skall kunna simulera en motor under transienta driftsfall med godnoggrannhet har undersökts. När detta är gjort, skall det undersökas hur väl dentransient kalibrerade modellen kan simulera en motor med förändrad rörgeometripå insugs- eller avgassidan, och vad som måste omkalibreras om detta inte ärfallet.Den viktigaste slutsatsen av detta arbete är vikten av att ha en korrekt framtagenkompressormapp i modellen. Den som fanns tillgänglig under arbetet hade baramätdata ned till 70000 rpm. Detta resulterade i en överskattning av massflödet iden lägre regionen i den av GT-Power framställda kompressormappen.
