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.

Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anaerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative aerobic and feed on carbohydrates in the silage.

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.

ABSTRACT (english)Introduction: The possibility to transplant an organ is an important part of the health care system, which demands great resources and a well functioning organization with a level of high competence. The work with organ donation is complex and brings forward a great amount of different emotions for the operation room nurse. Aim: The aim with the study is to illustrate the operating room nurses experience when the organ donor is brain dead. Method: Data collection has been performed with semi-structured interviews, which have been interpreted by qualitative manifest analysis. The design of the study is pilot towards a study in full scale.

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.

This essay highlights the Swedish retail companies? engagement in ethics and environment issues as a part of the business concept. The Customer is today more aware about what is going on in the world than ever before. Two of the main reasons are the Internet and the globalization. In relation to the customer being more aware about the situation in the world today, the demand for products which have been produced in consideration of ethical and environmental values has increased.

The practice of landscape architectural involves forming the space in our cities and suburbs, as well as the landscape surrounding. The need of exploiting green environment leads up to, among other issues, flood problem during heavy rain and overfed water environments. The problem is partially caused by the shortage of knowledge, how the environment is responding of the innovations made by the city- urban planning and how to get sustainability. Research and knowledge how to take care of our environment, in a natural way, is increasing. The object of the thesis is to propose control and balance in urban wetlands, and discuss the difference a plant design can do. The thesis deals with discourses in the field of landscape architecture, biological diversity, dam construction, limnology, planting design and management, pollution of the environment and urban design practice.

This study aims to discover pedagogues perceptions of children?s sedentary behavior linked to the school and its activities. Questions that the study sought to answer was: What do pedagogues think of when they hear ?sedentary children?. How do the pedagogues look at their own and the schools responsibility? Advantages and disadvantages with sedentary behavior? Relationship between physical activity and sedentary behavior and the impact of environment connected to sedentary behavior? The study is qualitative and implemented through seven interviews with pedagogues in the schools earlier years.

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.

Knowledge of ecological processes are a basis for the understanding of important environmental issues. Through qualitative interviews, 8 preschool class pupils have replied to questions concerning the concept nature, disintegration and environment. The aim of this survey was to examine what attitudes and knowledge children with different pedagogical background have about the nature and the environment.The result of this survey in whole demonstrates that all pupils have good and equivalent knowledge of the nature and the environment, independently of their different pedagogical backgrounds. A difference was however that children that have background from ?I Ur och Skur? (a Swedish outdoors preschool program) know the names of all small bugs that were in the survey.
