The aim of this thesis is to improve the control of urea injection at the combined power and heating plant Framtidens Gärstad (FTG). Tekniska Verken i Linköping AB is the owner of the plant.The FTG plant consists of a boiler where garbage combustion is done. From the combustion nitrogen oxides are emitted. These nitrogen oxides are hazardous to the environment. To reduce the nitrogen oxides, injection of urea into the boiler is used.

In this paper the authors are trying to understand what separates men from women when they save and invest their money. But also what factors that influence them in their decisions. To investigate how men and women actually act when investing their money the authors construct a survey. The authors also turn to the Swedish banks for information on how they think there customers are behaving. The authors find that men are more risk- taking than women and therefore invest more in products with higher risk, for example shares.

Patienter som är malnutrierade eller risk för sådan kan vara svåra att identifiera inom sjukvården, vilket i det postoperativa förloppet kan leda till komplikationer. Syftet med denna studie var att belysa vilken påverkan malnutrition kan ha på det postoperativa förloppet efter kirurgiskt ingrepp samt vilket tillvägagångssätt som används för att identifiera patienter med risk för malnutrition. Metoden var en litteraturstudie som granskade 10 vetenskapliga artiklar. Artiklarna hittades i PubMed, MedLine och Science Direkt. Resultatet visar att screeningmetoder som kan skilja på den underliggande sjukdomen och malnutrition är mer tillförlitliga. Behandlingen blir mer effektiv eftersom orsaken till malnutritionen identifieras och kan åtgärdas. Risken för komplikationer ökar ju mer malnutrierade patienterna är.

Syftet med denna studie är att undersöka varför triadiska köpprocesser avbryts och vilken som är den vanligaste anledningen till att detta sker. Vi vill få svar på om brist på tillit och upplevd risk, låg användarvänlighet eller bättre alternativ är anledningar till att triadiska köpprocesser avbryts. Vi undersöker även vilken av dessa tre anledningar som är den vanligast förekommande orsaken till att triadiska köpprocesser avbryts. Den empiriska datainsamlingen görs på e-handelsföretaget HinnerDu.se. Det teoretiska ramverket används som grund för den kvalitativa undersökningen som består av 30 intervjuer med personer som enligt empiriföretaget avbrutit köpprocessen på hemsidan.

Approximately 400 people in Sweden die each year by lung cancer caused by radon gas. Authorities have in recent years invested big resources and organized campaigns to encourage people to take action against high occurrence of radon in residences. With low frequency of applications for radon allowances as the main measure, a lot interprets on a very low commitment. The purpose of this thesis is to investigate the reasons for the low commitment among people. The study is based on a questionnaire survey sent to 444 house owners in Uppsala.

This thesis is a case study with a qualitative approach. The company examined is The Astonishing Tribe (TAT) making user interfaces for mobile phones. The company has had a growth of 1453% from 2002 until 2006. We have examined what are the key factors for keeping innovation while growing. The most significant factor not supporting innovation within the case company is the will to take calculated risks.

Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.

Människor har en viss mental kapacitet. Beroende på situation och uppgift belastas denna kapacitet olika mycket. Huvudhypotesen i detta examensarbete lyder "en persons mentala belastning ökar om hon/han upplever att risken ökar", oberoende av de krav uppgiften ställer, dvs uppgiftens svårighetsgrad.Undersökningen utfördes som ett experimentet med inomgruppsdesign och 24 försöksdeltagare. Två oberoende variabler med vardera två nivåer användes: Konsekvens, normal/ökad och Information om svårighetsgrad, normal/ökad. Dessa var avsedda att manipulera riskuppfattning.

The aim of this study is to examine which factors in the receiving-country that have had an influence on three now adult unaccompanied refugee children. The method used in the study is qualitative interviews with the three above-mentioned participants. The results show that some factors are perceived as helpful, having a positive influence on the participants life while other factors are perceived as worsening, having a negative influence on their life. Depending on the context some factors such as age, the Swedish language and housing arrangements have had both positive and negative influences on their life. Positive factors are among other things: access to good treatment and support, help with processing trauma and bad mental health, help with understanding coherence, access to a social network, family reunification, resilience and other internal factors.

In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.

Crisis management planning is a relatively new policy area in the European countries. It has materialized since the fall of the iron curtain and because of the increased interest to prevent wide-ranging national emergencies. In Sweden, the county administrative board has a key obligation to perform risk analysis guidelines. This assessment involves identifying crisis, planning response to the crisis and, if necessary, confronting and resolving the crisis in the geographic area of the region. The purpose of my thesis is to examine if there are any differences in crisis management planning between the county administrative boards? risk analysis guidelines.

Background: Since the start of the twenty-first century it has become very important for companies to act in a responsible manner, in guides of CSR. The idea is that companies have more responsibilities than to achieve a higher profit for their shareholders. They should also care about the society and act in a responsible way.Problem discussion: Problems concerning CSR are that the internal part of the sustainability work has not encountered the same level as the external part of the sustainability work. Companies are today struggling with implementing CSR into their business strategies.Research questions:1. What does a company has to consider when working with CSR? 2. How can management control systems help the implementation of CSR into the organisation?Purpose: The purpose of this thesis is to examine what a company has to consider when working with CSR and how management control systems can help the implementation of CSR into the organisation.

This master thesis has been performed at Sectra Communications AB in Linköping where they manufacture electronic encryption devices. In cryptology it is essential that an eavesdropper cannot find the plain text. To assure that a system is safe, all devices are thoroughly examined so that they don?t emit any secret information, so called Compromising Emanations (CE). This is done by comparing the secret signal with measured signals on the screen of an oscilloscope, a process that is very time consuming and furthermore, the risk of missing compromising emanations is high.
