Demonstratortest av gassensor baserad på tryckt organisk elektronik och jonledande papper
Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..
Vardagsmat eller domedag? Marknadsföring av ekologiska varor genom svaga och starka rädslor
In a time when concern for the environment is a topic that is met with both love and hatred, organic goods and services become increasingly common on the market. Communication efforts with the purpose of increasing the proportion of organic products consumed are being conducted by both private and public actors. However, achieving attitudinal and behavioral change within complex areas such as this comes with many difficulties.Within public opinion change, a common way of achieving a change in behavior is to use fear appeals and scare tactics. Earlier studies have shown that messages prompting a low level of fear can be more effective than messages prompting a high level of fear, since a high level of fear tends to raise defense mechanisms in the consumer. The purpose of this essay is to examine whether fear and defense mechanisms is a problem when it comes to making consumers choose organic products, as well as studying whether messages prompting low levels of fear are more effective than those prompting high levels of fear.This quantitative study is conducted in the form of a questionnaire-based experiment, comparing the effectiveness of two messages prompting different levels of fear.
Risk Management for commodity consumers -A study of the Airline industry-
The aim of this study is two folded. We wish to investigate if there is a value premium from hedging jet fuel exposure for American and European airlines. We also seek to answer if airlines can affect their probability to default by using Risk Management. During the period 2003 ? 2006 there existed a value premium for airlines that hedged their expected future consumption of jet fuel.
En komplicerad balansgång : familjebehandlares upplevelse av sin roll i arbetet med familjer i hemmiljö
The purpose of this essay is to analyse the descriptions of young girls' experiences of internet contacts, which have led up to sexual abuse. The aim is to give additional understanding and knowledge concerning grooming. Grooming means that somebody gets in contact with someone else with the intention of committing sexual violations at a later stage. In most cases this concerns adults who contact children. We have chosen to confine ourselves to focusing on the grooming on internet that has happened to girls. By means of thematic analyses of texts from the books Jag kände mig speciell, grooming på internet, 2012 and Alexandramannen, vår tids största nätsexhärva, 2009, we have found certain themes and linked them up with previous research-work and also theory of social psychology.

Disputing the Economic Man - a quantitative study on whether investor decision-making can be distorted by altering the presentation of an Exchange Traded Fund
During recent years, financial innovation has given rise to numerous structured investment opportunities aimed towards the general public. These have enabled private investors to engage in high-risk investments offering as much as 400 per cent leverage while oftentimes not fully having grasped the risk involved. The issuers of these securities have been criticized for using advertising of a too aggressive and misleading nature.By presenting 819 potential investors with two different investment opportunities yielding the same return over a six day period, we have aimed to assess whether the inclination of being affected by judegmental heuristics varies with factors such as knowledge, overall attitude towards the asset class, risk appetite and experience from previous investments.We have observed that investors' perception of the attractiveness of an investment can be distorted by altering the information presented to the investor. However, our findings show that this tendency decreases with an increased level of knowledge, experience and risk appetite..
Biogas : En systemanalys av Solna Stads matavfallsprocess
Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.
Barriers to convert to organic farming and the role of risk : an empirical application on Swedish data
To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.
IT-stöd för riskhantering : En studie av risk och kvalitetsarbete vid ZERT AB
This paper presents a project and literature overview about how risk management and quality sometimes goes hand in hand and sometimes in two different directions. Meaning that the risk management can affect product or process quality differently depending on what risks an organisation chooses to control.The purpose with this paper is to get a deeper understanding about how risk and quality works together with IT-support and therefore we have been actively participating in a project with a risk management company called Zert. A literature study and a qualitative interview study have also been undertaken to see what the customers and the other researchers have written, to be able to make proper conclusions on the subject.To easily work together and get the information that was needed, four methods where used. Besides the qualitative interview and literature study the think-out-loud, card sorting and a variation on the extreme programming method where used to help visualize and improve communication both with Zert, the costumers and among ourselves.Zert is a risk management company that helps other organisations to control their different types of risks that they might be taking, by offering a system where the risk management process is held and providing consulting services by helping within the processes. Both Zert and their customers see the communication, knowledge and teamwork as something important as well as the quality within the work, processes and the end result.
Modellering och reglering av ureainsprutning på kraftvärmeverket FTG
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.

Riskhantering i projekt : Modell för uppföljning
In April 2010 Vägverket (the Swedish National Road Agency) andBanverket (the Swedish National Railway Agency) will merge intoTrafikverket (the Swedish National Traffic Agency). Trafikverket willassume unified responsibility for the risk management that atpresent is responsibility of Vägverket and Banverket separately. Atpresent, as it will be shown in this thesis, Vägverket and Banverketshare the same theoretical background for risk management but usedifferent implementations often within the same agency. The use ofdifferent implementations results in a reduced transparency of therisk management both within and outside the agencies: this willbecome even more problematic when they will be fused intoTrafikverket.The aim of this thesis is to review the current risk managementmethodologies used at Vägverket and Banverket and to suggest aunified tool for the risk management at Trafikverket. This will bedone by focusing in particular on construction projects, one fromVägverket (Partihallsförbindelsen) and one from Banverket(Nynäsbanan).
Determination of anthelmintic resistance of Haemonchus contortus to three classes of anthelmintics in a Kenyan sheep flock based on results from faecal egg count reduction test
Haemonchus contortus is the most important bloodsucking gastrointestinal nematode in small ruminants worldwide. It is often controlled by anthelmintics. Even though other methods to control are available, the most efficient way to treat an animal with clinically manifested haemonchosis is to use one of the available broad spectrum anthelmintics: benzimidazoles (BZ), macrocyclic lactones (ML) or imidothiazoles-tetrahydropyromidines or the narrow spectrum drugs salisylanilides or nitrophenols. Anthelmintic resistance (AR) against all groups of anthelmintics in nematode parasites has been reported from many countries, and even multiple AR has been observed. In this study I have investigated the resistance levels to all major classes of broad spectrum anthelmintics in a naturally infected flock of sheep of Red Maasai sheep (RM), Dorper sheep (D) and their offsprings on a research farm in Kenya.
Gränsöverskridande företagsförvärv : En event study av systematisk risk
Internationaliseringen har ökat under de senaste åren, och företag väljer att lägga delar av verksamheten utomlands. Tidigare forskning undersöker sambandet mellan denna diversifiering och dess konsekvenser för företagen. Gränsöverskridande diversifiering och företagsförvärv bör enligt tidigare forskning ge en lägre systematisk risk då risken sprids ut över flera marknader.Syftet med studien är att se om tidigare forsknings resultat går att tillämpa idag när svenska företag gör gränsöverskridande företagsförvärv. Vi har valt att applicera en event study-metodik för att undersöka detta samband enligt marknadsmodellen. Studien undersöker 66 svenska fall av gränsöverskridande företagsförvärv, gjorda under perioden 2005 ? 2007.Resultatet visar att tidigare empiri, att företagen skulle ha lägre systematisk risk efter ett gränsöverskridande företagsförvärv, inte går att tillämpa idag på de svenska företagen.
?Det är mer plus, det måste det ju vara?? : En kvalitativ studie om att förhålla sig till kulturell bakgrund som kompetens
Several studies have shown that the Swedish labour market for different reasons is characterized by ethnical discrimination and that people who have another cultural background than Swedish are being excluded. Most studies done within this area have been focused on why it is harder for immigrants to enter the labour market and identifying the contributing mechanisms for this phenomenon. Instead the aim of this study was to see how the immigrants view their own cultural identity and background and how they perceive that their cultural competences are being valued when they apply for a job. To examine this, the following problematic was used: How does a person who has been brought up with both the Swedish culture and another culture look at using this as a cultural competence when they apply for a job. Two different theories were then applied to analyze the problematic, Erving Goffman´s theory about Stigma and Norbert Elias theory about the Established and the Outsiders.
