Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

The chosen task in this thesis is to compare two projects of importance on the impact on the approach to graffiti in Norrköping and Göteborg. My main source for empirical findings was interviews. I have examined the Norrköping project Canslit including legal graffiti walls and a graffiti school and the political process around it. This was compared to the Göteborg project kulturprojekt Röda Sten, which is a cultural center that happens to be covered in illegal graffiti. The conclusion was that due to the very detailed plans and well-functioning communications between actors in the Norrköping project, this has resulted in a creative, tolerant approach to graffiti still with low rate of illegal graffiti.

ABSTRACTMultiple sclerosis (MS) is the leading cause of adult disability inSweden. Hematopoietic stem cell transplantation (HSCT) can be used as a treatment option for patients with MS where the disease has an aggressive course. The treatment is preceded by high-dose chemotherapy which lowers the patient's immune system. It is therefore of interest to study infectious complications associated with HSCT in this patient.Aim: The purpose of this study was to identify infection problems in this population associated with HSCT, and to study differences in infectious complications between this group and patients diagnosed with lymphoma who have undergone the same treatment.Method: The study was a retrospective descriptive study with quantitative data. A medical record review was conducted.

Patients with mental illness experience dissatisfaction with their care due to lack of understanding and ignorance from the nurses. The nurses? approach might influence these patients' experience of their care. The purpose of the literature review was to describe nurses' approach in care of patients with mental illness. The literature review is based on an inductive approach and the result is based on 14 scientific papers, of which eight used a qualitative design and sex used a quantitative design.

Vocal Cord Dysfunction (VCD) is characterized by paradoxical vocal cord movement during inspiration or expiration, and generally affects adolescents and predominantly women. Previous studies have shown a large inconsistency concerning terminology, definitions, etiology, assessment, differential diagnosis, co-morbidity and treatment. The purpose of this study was to map knowledge on and management of VCD in Sweden. The study was conducted as a written survey addressed to speech-language pathologists and physicians, and attained an answer percentage of 79 percent. The results showed that several professions were involved in the management of these patients, but no clear pattern of referral could be observed.

Developments in milk production are heading towards fewer but larger herds where the milking process is often fully automated. Automatic milking systems were launched in the 1990?s and in the year 2010 the Automatic Milking Rotary (AMR) was introduced. As a rule there are no supervision personnel present during the milking event in systems with automatic milking. This means that there is a risk that cows can be incompletely milked in one or more udder quarters, for example if the robots fail in attaching the milking cups or if the cow kicks off the milking unit.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).

Today, there are few industries left in our cities. Industrial areas thatare located in urban settings close to water or city centers are oftenreplaced by housing. In my thesis I want to explore how such industrialsite located in an urban setting can be transformed into anindustrial park where the industrial structures are saved. By approachingthis type of environment in a positive manner, I wish tohighlight the potential aesthetic and functional value in the existingindustrial structure. Through the transformation and design of anexisting industrial site I will convey the previous use and history ofthe place.The wastewater treatment plant, Kungsängsverket, is located in thedistrict of Kungsängen in the southern part of Uppsala.

Our aim with this study is to explore socialworkers perception of what is a good treatment is and how to establish good relationship with their clients. We have decided to limit our study with social workers in Economic assistance and Abuse Units in social servises and explore if we can discern any differences between the units. We have chosen to use qualitative methods to achieve the aim of this study. We interviewed a total of seven social workers, of which three were from Abuse unit and four were from Economic assistance unit. One of the theoretical frame we have used is Goffmans (1970, 1974) theories about social interaction in which he explains the social encounter between social workers and clients.

Background: A health damage that has been specifically related to nursing is pressure ulcers. Pressure ulcers are a complication caused by disease, care and treatment and can result in great suffering for the patient. Pressure ulcers can affect people both physically and psychosocially and is experienced, by most patients, as a serious and unnecessary complication of care. Today there are hundreds of identified risk factors for pressure ulcers described that can be divided into patient and care-related risk factors. A successful pressure ulcer prevention and treatment is to reduce or eliminate the underlying causes for the development of pressure ulcers, prevent deterioration and to treat existing ulcers.

Our purpose with this essay is to examine how staff that works with drugaddicts in compulsory-treatment institutions for women and men uses gender in their work. We are trying to get knowledge and understand how the staff is using their own and the client's gender in the work that they are doing. We have chosen to take focus within women's care in institutions and compare if the work is done in the same way with male clients.Our essay is based on interviews with treatment-staff. We have used a qualitative method. The interviews are made with both men and women.

Concentration problems have been discussed from a variety of angles and have been problemized in different ways. One approach is to place the major part of the problem on the child independent of its environment. The terms used as an explanatory model are ?attention disorder, impulsiveness, difficulty at finding suitable activity levels, difficulty in understanding rules and instructions? (Kadesjö 2007). Others place the root of the problem in the environment prevalent at pre-school and school.

Every year about 30000 people have a stroke. It is caused by either a bleeding or a blood clot, and depending on where the damage is, the patient can get different types of difficulties following after the stroke. About 40 % of all stroke patients sufferfrom some kind of speech and/or communication difficulty, like aphasia or dysarthria. As hospital staff it´s important to know how to communicate with these people, to get a deeper understanding regards their needs.Aim:The aim of this study is to out of a patient's perspectivedescribeexperiences ofcommunication difficulties that can follow after a stroke.Method:A content analysis with a qualitative approach was used to analyse five autobiographies.Results:The result showed in what way stroke patients experienced their communication difficulties, and how they felt about the hospital staffs treatment related to their communication difficulties. During the analysis two major themes emerged: suffering and wellbeing.
