Förbättrad förbränningsstabilitet i EBK för turbofläktmotor RM12 genom förändrad motorreglering : Improved afterburner combustion stability for turbofan engine RM12 by modified engine control

The engine of JAS 39 Gripen, RM12, has recently been equipped with a new flameholder and a new engine inlet. This change has caused an increased noise level from the engine when the afterburner is in use. The noise level reaches its peak when the afterburner is partially used. The problem is thought to be unstable combustion in the regions around the flameholder. A solution to the problem has been proposed by Volvo Aero.

Preventiva trycksårsåtgärder. En litteraturstudie

Trycksår kan förekomma på alla typer av vårdavdelningar och tar lång tid att läka samt är en stor kostnad för samhället. Syftet med litteraturstudien var att undersöka åtgärder för trycksårsprevention. Metoden är baserad på en modifierad version av Forsberg & Wengströms modell för en systematisk litteraturstudie. Sökning i databaser PubMed och CINAHL utfördes och resultatet i litteraturstudien grundades på nio kvantitativa vetenskapliga artiklar. Författarna kunde identifiera olika preventionsåtgärder där framför allt evidensbaserade bedömningsinstrument som Modifierad Nortonskala och MNA-SF är viktiga att använda i trycksårsprevention, men även temperaturmätning, ?Continental anal plug? (CAP), god nutrition, aktivitet samt tryckreducerande underlag som fårskinn..

Är klassröstningen fortfarande signifikant? - en studie om kommunalvalen i Stockholm och Göteborg 2002

The association between social parameters (i.e. socio-economy and level of education) and voting behaviour has been reviewed and analysed based on data from municipal council elections in Stockholm and Gothenburg in 2002. Some social scientists argue that the class voting is in decline and that new social cleavages have emerged. However, by using regression analysis techniques, this study implies a strong dependence of voting behaviour on social parameters, such as socio-economic status (SES) and level of education. Socio-economy appears to be a dominant predictor in the analysis.

Rättvis värdering av hälsa : En kvantitativ jämförelse mellan Person Trade Off- och Time Trade Off- metoden

One must consider cost effectiveness when deciding how resources within the health sector should be distributed. Quality adjusted life years (QALYs) are used to measure the value of different medical treatments. QALY is based on utility maximization theory, which suggests that a QALY is always a QALY regardless of who receives it. Therefore, a produced QALY is worth the same regardless of the age or the initial health of the patient. Previous research has shown that these assumptions do not seem to fit the real preferences of individuals.

ST-läkares identitetsarbete: En studie av läkare under specialiseringstjänstgöring

The results from 13 interviews and one opinion poll answered by resident physicians were interpreted as stories about identity as primary material for this thesis. The resident physicians stress the importance of considering whether their work primarily concerns curing people from diseases or if the process of working with sick people also includes how to handle the pressure of work, either by adapting to it or changing it, and the search for balance between work and private life. Residents separate themselves from older physicians by saying that younger physicians accentuate empathy to a greater extent while older physicians emphasise a high work load. Identity seems to effect how the residents perceive and relate to their work, themselves as residents and different types of patients..

Svarstiden vid klinisk bedömning av högre språkliga förmågor hos vuxna

The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion.

Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.

Studenters förhållningssätt till valet av framtida bank

Since the middle of the 1980´s the Swedish bank market has experienced a change concerning structure and pressure of competition. Before the year 1985, the market was characterized as a market with few operators but have changed to a market with many operators and seen as one of the most intense in Europe where the four major banks; Nordea, Handelsbanken, SEB and Föreningssparbanken together have a strong position. Their market share has recently decreased, mostly for the benefit of foreign banks and niche banks. The Swedish market has experienced difficulties in generating profits which mostly depends on new establishments that have increased the pressure on competition, a low growth as well as weakened customer relations. The development has resulted in a growing importance of market segmentation, mainly by the fact that costumers have become more disloyal as a result of the increased competition.Students are a market segment of interest for the financial market, mainly because of the expectations of their positive financial situation in the future.
