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.

Farmers are required to make sure that cattles basic needs are met, but still every year cases of neglect occur where the farmer has not complied within the animal welfare law and regulations. The aim of this study was to investigate how cattle are affected physically and behaviourally by neglect in the form of underfeeding, starvation and lack of sanitation, which animals are most vulnerable to the impact and what prospects they have to recover. The study was conducted as a literature study and the results show that these types of neglect have a large impact on the cattle welfare. Underfeeding and starvation causes physical changes leading to reduced milk production, reduced muscle mass, impaired immune function, poor reproductive performance and changes in rumen microflora leading to decreased number of microbes and pH change. Physical changes due to the lack of sanitation consist of increased vulnerability to hoof diseases and mastitis, burns, and increased sensitivity to temperature.

Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.

Sow shoulder lesions are a common form of decubital ulcers in sows. The wounds are often bilateral and affect both loose housed and restrained sows. In most cases shoulder lesions develop after farrowing and heal after weaning. Sows that once have had decubital ulcera are however more proned to develop new wounds after the next farrowing. The problem is multifactorial and a number of risk factors have been described, including body condition, body size, parity, time spent lying down, flooring, moisture, breed, body temperature and some herd factors. The aim of this study was to investigate whether the height of the tuber spina scapulae is a risk factor for the development of decubital ulcers.

Background: Chemotherapy and radiation resistance are major causes of failure in cancer treatment. The response to treatment in cancer cells depends on several mechanisms and pathways such as Janus kinases-signal transducers and activators of transcription JAK/STAT pathway. STAT1 was the first described transcription factor in the STAT family. STAT1 is activated by stimulation of signaling proteins such as type II interferon (IFN- ?) and the activated STAT1 translocates from cytoplasm to nucleus.

AbstractThe aim of this essay is to explore how teachers and leisure educators can strengthen and increase students? self-confidence in different ways in their line of work. I chose this inquest for personal reasons and also because it will be of great aid for me since this is what I intend my future profession to be. For this inquest I have chosen to do five qualitative interviews and two unstructured observations. The inquest was also based on relevant literature connected to its purpose.The results show that self-confidence is linked to something the individuals accomplish and that self-esteem is the way they see themselves, an inner feeling.

Bakgrund: I den fysiska vårdmiljön framkom olika förutsättningar för att skapa god omvårdnad då grundläggande mänskliga värderingarna var av betydelse för hur begreppen hälsa och omvårdnad tolkades. De traditionella vårdmiljöerna kunde uppfattas som anonyma och sterila platser av både sjukvårdspersonal och patienter, dessa egenskaper representerar hur fysiskt påtaglig sjukvårdsmiljön var. Syfte: Syftet med denna litteraturöversikt var att beskriva hur patienter inom somatisk vård upplever den fysiska vårdmiljön på sjukhus. Metod: En litteraturöversikt baserad på tio vetenskapliga artiklar med både kvalitativ och kvantitativ ansats. Resultat: Tre huvudteman framkom vid analysen av artiklarna; sjukhusmiljö, vårdavdelningsmiljö och vårdsalsmiljö.

The aim of this Master's thesis is to examine what effect two different models of acquisition have on user satisfaction with information resources at academic libraries. The two models examined are the traditional model where a subject specialist librarian makes the selection, and the user-governed model where the larger part of the selection is based on user requests. The scope is the libraries of Roskilde University, which employs the traditional acquisition model and Malmö University, which employs the user-governed. Both libraries have a user-oriented approach to acquisition. The study encompasses a close examination of the acquisition policy through document analysis and interviews with the librarians in charge of acquisitions at each university, as well as a user-satisfaction survey among the professors and senior teachers on two faculties at each university respectively.

Aim and Hypotheses The aim of the study was to investigate how episodic hypoxia affects resting blood pressure and the acute blood pressure response in healthy older adults. The following hypotheses were formulated for analysis in the study: Blood pressure increases acutely in healthy older adults during exposure to 150 minutes of hypoxia with SpO? 80%. Resting blood pressure decreases in healthy older adults after 15 repeated exposures of 150 minutes of hypoxia with SpO? 80% over a period of three to four weeks.

The aim of this thesis is to investigate how librarians view marketing of the library using social media and how this can be used in a marketing strategy. The theoretical framework for this thesis is based on the 7 Ps of the marketing mix, SWOT-analysis and SWOT/TOWS Matrix. The theory is based on planned elements that make up a product or service offered the market. We have used our own interpretation of the theories to analyse our material. Our main method has been a web-based questionnaire, the questionnaire was sent to 523 librarians active at ten large public libraries and its related branches.

Lake lowering in sulphide-rich areas is currently a major environmental impact for surface water. This study focuses on whether there is a relationship between a gradient of lake lowering and surface water impacts in areas of sulphide-rich sediments, in order to better understand their contribution of heavy metals and sulfuric acid. Also, is it a reasonable method to use the reduced lake area in order to quantify the gradient? The survey was conducted by collecting water samples from reference lakes and lowered lakes from south to north in coastal areas within the county of Västerbotten. Water samples were then analyzed for TOC, pH, conductivity, anions, base cations, alkalinity, acidity, sulfate, Al, Cd, Fe, Mn, Cu, Zn and Pb.

Traffic accidents where wild animals are involved represents between 60 and 80 percent of all reported accidents, depending on location in Sweden. In a country like Sweden, with a lot of forest, there is always risk of a collision with a wild animal. Imagine if you, as a road user, had the possibility to receive warnings when the risk of an accident according to statistics is extra high.Wildlife Detection Network is a wildlife warning system with an information service, which makes the whole concept unique. When an animal is approaching the road, it is registered by sensors, and warning lights along the road are lit to inform drivers of the potential danger. In conclusion, this is a direct warning to all drivers on the road where the system is placed.When an animal is registered by the sensors, information containing time, date, weather circumstances and coordinates are sent to a database.

Det primära syftet med uppsatsen är att studera relationerna mellan de nya och de etablerade börsmarknaderna i EU för att se om det ha skett någon förändring under perioden 1996-2005. Ett sekundärt syfte är att undersöka huruvida den finansiella integrationen inom unionen har blivit starkare under den studerade tidsperioden. I syfte att kunna besvara de frågor som vi är intresserade av använder vi oss av VAR-metoden. Med hjälp av "impulse response" beräknade vi hur snabbt en händelse sprider sig mellan de undersökta börsmarknaderna samt hur lång tid det tar innan dessa åter är i jämvikt. "Variance decomposition" talar om för oss i vilken utsträckning de olika börsmarknaderna påverkar varandra.
