A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

The purpose of this study is to increase knowledge and clarify how active educators regard ICT- tools as aids, both the educators currently using the ICT- tools to improve writing skills and educators who have not yet embraced it. The study is based on four interviews with educators working within the age groups grade 1- 3. The findings of this study show a strong commitment among all educators, in terms of students' writing skills and their different approaches to working with writing skills, which is important as one method should not preclude another. In the findings a considerable curiosity can be seen for ICT- tools for writing instruction by the educators who have not embraced it. The interest and commitment of the educators who have embraced ICT- tools in their teaching is great..

The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings. A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce. In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils. The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season. The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.

  ?this Unpleasent klientel?A study on refugee care in Växjö between the years 1944 and 1947.The purpose of this study was to examine the treatment of sick refugees in Växjö in the 1940s. To achieve this a combination of quantitative and qualitative methods were used. The material found in the local archive and local newspaper was then put together and analyzed from the theoretical perspective, gender, class, ethnicity and social status.The result of this study shows that there were two main treatment wards for refugees, one that was supposed to treat women and children with active tuberculosis and the other ward treated refuges with ?epidemic diseases.? Foreign citizens were also taken care of in other words that were also not meant for refugees only, like the Epidemic hospital, which treated about 80 patients of a foreign nationality between 1944 and 1946.

Background: In scientific literature there are various treatment programs for people with alcohol dependence described, however, are psychosocial factors that promote recovery process described to a limited extent.Purpose: To describe the psychosocial factors that promotes recovery from alcohol dependence.Method: Literature study of ten scientific articles, published between 1999-2011 with both qualitative and quantitative design.Results: According to the literature, the recovery process can be considered to begin when a person with alcohol dependence reached his personal rock bottom. The longer the recovery progresses, the greater are the overall level of performance. Social support is described as an important factor to prevent relapse and reduce the need for professional help. Self-belief and support of self-help groups are described as important to maintaining sobriety. Social support and influence from family members was related to increased ability to analyze and assess their situation during the recovery.

Title: The nurse's dilemma in psychiatric inpatient care - a balancing act between good and evil Objective: To describe the nurse's experience of relieving patient suffering caused by coercive measures on a closed psychiatric ward . Frame of reference : The results are discussed in light of Eriksson´s theory of suffering and caring relationships Method: A qualitative analysis based on focus group discussions Results: The analysis resulted in six categories, to protect the patient , to involve the patient , not to lose control , to remain , to justify compulsion , and to be touched . The results showed that nurses had the experience of being able to relieve the suffering of patients caused by coercive measures. It was also found that the nurses had a tendency to justify coercive measures , the more experience they had of performing these . Conclusion: The results describe that nurses have the experience and knowledge of how to relieve patients' suffering caused by coercion but also their experiences of performing these .

This master's thesis deals with how a school class of 19 students that are 12 years old,perceive the conception of the library and its activities, and how this can be studied by usingfour different approaches: analysis of the children's drawings, analysis of the children'sessays and analysis of their answers to questions in an inquiry and in interviews. Theories ofhow children learn, develop and perceive the world are briefly presented, as we11 as theorynecessary for the analysis.The four different techniques produced in general the same result; the children displayed thesame thoughts, knowledge and values in the drawings, in the essays, in the inquiry andduring the interviews. The children participating look upon a library as mainly a building,though sometimes also a room, where there are books..

The aim of this study has been to investigate a group of upper secondary school teachers? approach to work with the ethnic multi-culturalism that characterises the Swedish society of today and to point to the obstacles and possibilities the teachers see to work with this. With the help of interviews with eight teachers satisfying results could be reached. The results showed that it was possible to distinguish three different ways to think and act when it comes to the work with ethnic multi-culturalism in school and teaching. The approaches entailed different consequences on the way the teachers conduct their teaching.

Inledning: Syftet med föreliggande studie var att testa interbedömarreliabiliteten för det i Sverige vanligaste triageinstrumentet Rapid Emergency Triage and Treatment System (RETTS). Instrumentet består av 42 kontaktorsaker (ESS) som kombinerat med mätta vitalparametrar, t.ex. blodtryck och puls, ger en triagefärg. För att kunna bedriva evidensbaserad omvårdnad krävs att instrument, skalor och metoder är valida och reliabla. Statens beredning för medicinsk utvärdering anser att RETTS saknar både validitets- och reliabilitetsdata.Metod: Två ESS från instrumentet valdes.

This thesis has been carried out in collaboration with LEDtec International AB. LEDtec focuses on innovative solutions in LED screens. Everything from large advertising signs to welcome signs in cities, to screens indicating speeds or warning of heavy traffic. The task was to was to help them develop a new version of the control board that is used in some of their products. The reason for this is that their old control board is obsolete and the components that are on it, is no longer manufactured or in need to be renewed.

Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s.s. (Fr.) Bref.) and the S-type (Heterobasidion parviporum Niemelä & Korhonen). Therefore a lot of research has been carried out in this topic to find a solution and reduce this problem, one alternative that have shown to be profitable is stump treatment in thinnings.
