This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.

Studiens syfte var att undersöka om patienter upplever att de fått tillräckligt med information inför sövning vid operation. Information är en viktig del i omvårdnaden, för att skapa en trygghet hos patienten. Många patienter upplever oro inför sövningen, vilket kan minska om patienterna är välinformerade. Studien bedrevs med en kvantitativ ansats som en enkätstudie på sju avdelningar på Karolinska sjukhuset, Huddinge. Frågeformuläret konstruerades av författarna inför studien och testades i en pilotstudie.

The Energy Market Inspectorate is implementing a new tariff regulation in Sweden. A small part of the new regulation concerns effectible operation costs and originally they where intended to be calculated using a modification of equivalent comparison standards, in Swedish Ekm. This thesis is intended to analyze if Fortums grid in Stockholm could be described correctly, using equivalent comparison standards. In Ekm every part of the distribution grid is designated a weighting in relation to 1 km 0.4kV over head line. These Ekm-measurements are intended to simplify comparison between different grid areas with different structure and geographical conditions.

Att sövas inför en operation innebär att lämna över kontrollen av sina livsfunktioner och är en situation många patienter känner oro inför. För att kunna utveckla anestesisjuksköterskans preoperativa omhändertagande är kunskap om patienters upplevelser av omhändertagandet nödvändigt. Dessa upplevelser kommer att studeras med utgångspunkt i en teoretisk begreppsmodell om personcentrerad vård.Syfte: Att beskriva patienters upplevelse av det preoperativa omhändertagandet inför anestesi.Metod: Kvalitativa semi-strukturerade intervjuer kommer att genomföras med ett tiotal personer som i slutenvården genomgått en operation i generell anestesi. Intervjuerna kommer att analyseras med kvalitativ innehållsanalys. För att testa metod och forskningsplan genomfördes en pilotstudie där två forskningspersoner som nyligen genomgått en operation i generell anestesi intervjuades.

Bakgrund: ?rligen opereras cirka 400 000 patienter inom slutenv?rden i Sverige. Det finns forskning som visar upplevelsen av att v?nta p? en elektiv operation, dock saknas det forskning om hur patienterna upplever v?ntan p? en akut bukoperation. Specialistsjuksk?terskan beh?ver kunskap om och f?rst?else f?r hur patienterna upplever sin v?ntan p? en akut bukoperation f?r att kunna bem?ta patienten och ge trygghet.

To make wave power more competitive on the market Uppsala University leads projects that examine how to accomplish better efficiency in the production. One of these projects is described in this report and examines whether it is possible to make the production of dovetails more efficient by using an industry robot of type ABB IRB6000 S3 M91. This project is using an already presented working method, from a previous project, which involves that the robot picks up the dovetail and moves against fixed cutting machines where the dovetail will be drilled, threaded and milled. Drilling and threading are the sub operations that will be examined in this project where experiments are made with the presented working method and with equipment from Uppsala University.Experiments show whether it is possible to drill the holes in the dovetail within specifications by using the specific robot and the presented working method. The threading operation is examined theoretically if it is possible to accomplish by using the same working method.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Many organizations strive to be transnational. This means that individuals with different cultural background will work together. Countries around the world have their own culture, which mark the way individual?s think and act. Different values between leaders and their subordinates are often a key factor to misunderstandings and conflicts in transnational organisations.

Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.

A new phenomenon on the Internet is the online audience response. Mentimeter is a web-based tool where you can create online polls. The users can then cast a vote and the result is shown in real time. We want to test the information visualization in Mentimeter and we base our hypothesis, that a better graph design is possible, on the work of Edward Tufte and Stephen Few. Edward Tufte is an emeritus at Yale University, where he held courses in statistical evidence and information design and has created theories about how visual information should be designed.

The purpose with this review is to investigate evidence-based practice (EBP), and which arguments are used to justify EBP. The year of 2006 Bergmark and Lundström published an article regarding the problems concerning EBP. They are discussing that several different definitions of EBP are existing, which they mean can lead to difficulties using the EBP-methods in real life. In this study six articles, from the years 2007-2011, have been analyzed using Mertons structure-functional theory and Lipskys theory of street-level bureaucracy. Different definitions of EBP are discussed in the articles and there seem to be a need to clarify the concept.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.

Forskning beskriver kraftig övervikt relaterat till fetma som ett svårbehandlat tillstånd där gastric bypass operation kan vara ett alternativ till viktminskning. Studier visar på att nyttan övervinner riskerna då dödligheten minskar i den grupp som genomgår operationen. Dock är övervikt relaterat till vissa risker inom anestesin som sjuksköterskan ställs inför. Problem med att etablera en fri luftväg samt intubationssvårigheter är två huvudsakliga problem anestesisjuksköterskan ställs inför. Därför är det viktigt att ligga steget före som anestesisjuksköterska och vara förberedd på eventuella komplikationer.

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.
