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.

The research of the essay will be about Solidarity, the Polish trade union that began to rise in the beginning of 1980. In more specific tendencies to the empirical study, it is interesting getting to know about when the free trade union was created with a view to liberate the Polish people from Communism.The essay will be studied as an empirical case study, with a qualitative text analysis. The content will also include how power is allocated to the political, economic and social aspects of the national, and international relations. Therefore it will be relevant to use a method of ideology analysis to the qualitative text.The result of the theoretical analysis was that it is difficult to apply the social movements into a political change, even if it leads to success. According to this, participants in social movements are able to use the most potential and most necessities of resources, just as activists tend to do in reality..

The main purpose of this study is to find out what kind of help social service in one selected municipality in Sweden can provide for children who have witnessed or been victims of domestic violence. Using focus group interview this study investigate how the social workers meet the needs of these children. The bases for our analysis are the Organization Theory and the Attachment Theory, as well as previous research. Important results are that the social services are dependent on notifications in order to do their work and that the most common interventions are foster care, emergency foster care and/or family therapy. The difficulties that social workers perceive their work are unjustified families and heavy workloads.

Background: An indisputable right for nurses is to have a safe and secure work environment so they can deliver a high quality care. To bring a clear definition of what threat and violence are, is an important part in the work to prevent threat and violence. One part of the problem is that the experience and understanding of threat and violence can be different from one person to another. Aim: The aim of this quality study was to emphasize Nurses experience of threat and violence at workplace. Method: The method used in this study was qualitative interviews in the sense to bring out the nurses experience.

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

The Intensive Care Unit (ICU) is a special unit for patients who is in the need for emergency life-sustaining measures and every patient has complex medical- technical equipment. The experiences of a critical illness and the needs of critical care are experienced in different ways. The purpose of this study was to describe the experiences from patients in the ICU and how this experience has an influence on the patients. The method was a study of literature with a qualitative inception based on eight scientific articles and the analysis of content has been inspired by Graneheim and Lundman (2003). The result of the study is presented by four categories: to loose the ability to make themselves understood, to be forced to adjust to the environment of caring, to have the lack of connection with reality and to be in an intensive care environment, The results showed that patients in the ICU are affected by the attitude from the staff, the equipment around them as well as the sounds and lights in the environment there.

Sigtuna är en av de äldsta städerna i landet. Kyrkan S:t Olof är en av flera medeltida kyrkor i staden. Under hösten 2005 utförde Leica Geosystems en demonstrationsmätning med en laserskanner i S:t Olofs ruin. Från museets håll ville man därefter att hela ruinen skulle mätas upp tredimensionellt för att på ett bättre sätt kunna analysera komplicerade kronologiska händelser och förändringar.Man har tidigare inom vetenskapsgrenen byggnadsarkeologi upplevt problem med att åstadkomma en fullständig bild av en byggnad genom tvådimensionella ritningar. I en tredimensionell avbildning synliggörs rummet på ett mer fullkomligt och verklighetstroget sätt.

Physical activity is required for a good health and science shows a clear connection between exercise and a lower risk for disease. Still, the physical activity among the population is far from good. It is the individuals own responsibility to exercise, but the society also has a responsibility to give opportunities to exercise for the population. The aim with the study was to investigate what motivated the group of physical active people to use the Central hospital in Kristianstad?s health program.

Bakgrund: Specialistsjuksköterskan ska uppta patientberättelsen och utifrån sinspecialiserade kunskap om medicinska eller psykiatriska tillstånd göra en korrekt bedömning.Sjuksköterskan ska från sin bedömning sedan förse patienterna med adekvata vårdåtgärder. IGöteborg har andelen ambulansuppdrag som klassificeras som psykiatrisk sjukdom ökat desista åren. Med anledning av det planerar ambulanssjukvården i Göteborg en speciellpsykiatriambulans med dubbelkompetens, en sjuksköterska som har specialistkunskap inompsykiatri samt en ambulanssjuksköterska. I Stockholm skall en psykiatriambulans införas 1april 2015 men inte med dubbelkompetens. Anledningarna till planen att introducera enpsykiatriambulans är att utveckla den akuta prehospitala vården bland annat genom att hjälpapatienter med psykiatrisk problematik till rätt vårdnivå.

Vår målsättning med detta examensarbete var att ta fram en nödbogseringsmanual till skolfartyget Calmare Nyckel. Denna skulle vara helt i enlighet med de regler och riktlinjer som fanns tillgängliga och underlätta beslutsfattandet för besättningen i situationer som kräver nödbogsering. Projektbeställare var Bengt Karlsson, befälhavare på Calmare Nyckel, och efter ett inledande möte sattes arbetet i gång då i form av ett projektarbete inom ramen för examensarbete. Vi har baserat manualen på i första hand aktuell lagstiftning och riktlinjer men också på andra fartygs nödbogseringsmanualer vi bedömde som bra.Arbetet förflöt enligt utsatt tidsplan och det slutgiltiga resultatet blev väl utfört enligt oss och projektbeställaren.Calmare Nyckel är nu utrustad med en fullt fungerande nödbogseringsmanual som vi med säkerhet kan säga uppfyller alla tillämpliga krav som ställs på en sådan. Vår förhoppning är att manualen aldrig kommer att behöva användas i skarpt läge, men däremot regelbundet fungera som underlag i övnings- och utbildningssyfte..

During spring 2001 we have been involved with our bachelor thesis at Doberman Digital Agency, an Internet related webdesign company. We have focused our work on the registration process via digital medias such as the Internet. During our workprocess we have been conducting a number of studies and analyses of workrelated materials. Ethnographical methods such as structured interviews and participant observations were primarily used in our work. We also widely used brainstorming in our designprocess.

SAMMANFATTNINGAmbulanssjuksköterskan har en komplex arbetssituation, hon ska självständigt bedöma och behandla akuta tillstånd hos patienten. Arbetet försvåras av flera faktorer, tiden med patienten är i regel kort, möjligheten till rådfrågning är liten, utrymmet och tillgången till hjälpmedel är begränsade. Trots det ställs höga krav på vården i ambulansen, många gånger samma krav som på vården på en akutmottagning. Ett av dessa krav är en god dokumentation, kraven på patientjournalen är desamma i ambulansen som i övriga vården. I journalen dokumenteras uppgifter om iakttagelser, omvårdnadsåtgärder, medicinska åtgärder och information rörande transporten.

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.
