Ledproteskirurgi av höft- eller knäled är idag en av de vanligaste operationerna i Sverige. Den vanligaste orsaken till ledproteskirurgi i höft och knä är artros som orsakar kronisk nedbrytning av leder. I den postoperativa vården är patienter utsatta och behöver hjälp av vårdpersonal med rehabiliteringen och smärta. Under denna vårdtid utvecklas en vårdrelation mellan patienterna och personalen, som påverkar patientens livskvalité. Syftet med studien är att belysa patienters upplevelse av personalens bemötande i samband med postoperativ vård efter operation av höft- eller knäprotes.

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Den bullerreducerande beläggnigen har en porös struktur som förbättrar dräneringen och reducerar buller vid källan men egenskaperna orsakar ett snabbt slitage och portäppning. Detta medför att beläggningen måste omläggas och rengöras oftare än en konventionell beläggning som t.ex. ABS 16. Kritiken mot den bullerreducerande beläggningen riktar sig på de höga drift- och underhållskostnaderna, detta gör att många väghållaren satsar på bullerskärm som bulleråtgärd.  Syftet med arbetet är att jämföra bullerreducerande beläggning med bullerskärm, för att reda på vilken bulleråtgärd är mer kostnadseffektivt under 20 år. Ett teoriavsnitt kommer att förklara och beskriva på ett tekniskt sätt: väg, ljud och buller, bullerskärm och bullerreducerande beläggningar.Kostnadsjämförelsen mellan bulleråtgärderna omfattar investering, drift och underhåll.

BackgroundDiathermy is the most commonly used surgical instrument in the surgical area today. Diathermy is used in surgery to cut and coagulate tissue. The use of diathermy releases chemical substances in to the environment in the form of diathermy smoke. Research shows that these chemical substances pose health risks to both staff and patient exposed to the smoke. To protect the interdisciplinary, perioperative team from the smoke, smoke evacuation systems can be used.ObjectiveThe purpose of the study is to highlight the work environment of the perioperative team when working with diathermy smoke.MethodThe study is meant to be implemented as an empirical descriptive sample survey.

The aim of this study is to explore local cultural policy documents in the municipality of Gothenburg Sweden, and, more specifically, to investigate the concepts of cultural planning and instrumental cultural policy. Cultural planning is in this thesis seen as a result of an instrumental view of cultural policy. The theoretical framework consists of the theories of Danish cultural policy researcher Dorte Skot-Hansen. She describes cultural policy in urban areas as founded in motives such as economy, social issues, entertaining and enlightenment. A qualitative text analysis is performed in order to see if the purpose of the cultural policies is to focus on cultural planning as formulated in the document Kulturpolitisk strategi ? version 1.0, adopted by the city council in 1998.

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.

This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.

Bakgrund: Bröstcancer är den vanligaste tumörformen hos kvinnor och den ärftliga faktorn bidrar till 20-30 %. Den ärftliga bröstcancern utvecklas vanligtvis i 30-40 års ålder. Idag erbjuds kvinnor genetisk utredning för att undersöka om de har hög risk för att utveckla bröstcancer. Syfte: Studiens syfte var att beskriva kvinnans upplevelse av sin livsvärld, vid risk för att utveckla ärftlig bröstcancer. Metod: Studien genomfördes genom en systematisk litteraturstudie, med inriktning på kvalitativa artiklar. Resultaten analyserades med inspiration från Burnards innehållsanalys. Resultat: Det som framkom var att kvinnorna kände sårbarhet i samband med genetiskt test, de kände den ärftliga utsattheten både för sin egen, barnens och anhörigas del, valet att ta bort eller behålla sina bröst, de kände behov av stöd i samband med att i förebyggande syfte ta bort brösten samt de upplevde en förändrad kroppsbild. Slutsatser: Det finns mycket som tyder på att kvinnors livsvärld påverkas av att operera bort brösten i förebyggande syfte. Denna litteraturstudie har väckt intresse att genom en empirisk studie forska vidare om vårdpersonalen bemötande till kvinnor som väljer en förebyggande operation.
