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..
Att ragga på de svårflörtade: Om värdet av kampanjsajter för besökare och annonsörer
Campaign websites are a growing Internet based type of advertising, dependent upon the advertisement being actively pursued by consumers. The popularity of campaign websites stands in sharp contrast to the increasing advertising boredom among consumers often discussed in both public media and academic contexts. Despite the increasing importance of this kind of communication, little academic research has been conducted on the subject. The purpose of this thesis is to investigate the value of campaign websites for advertisers and consumers. Through a quantitative web based field study combined with an exhaustive qualitative study, we can draw conclusions concerning campaign websites and contribute with a theoretical framework for this type of advertising.
Hur viktig är statens styrka för ekonomiskt välstånd?- En studie av alla världens länder
What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

Värme & El med Stirlingmotor
En billig och robust motor av stirlingtyp har konstruerats för användning i villor. Som energikälla används de heta rökgaserna från förbränningen i husets panna. Motorn driver en generator i permanent drift under den kalla delen av året då värme- och energiförbrukningen är som störst i vårt land. Under den varma årstiden finns den tillgänglig som reservkraftverk. Tanken är att stirlingmotorns värmare ska placeras i en villapanna för att ta till vara exergipotentialen hos dess höga temperatur.
Observiaire och film som analysmetod för cykeltrafik : En fallstudie på Götgatan i Stockholm där omställningen till supercykelbana utreds
The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.
Utveckling på höga höjder : en fallstudie av Åres destinationsutveckling över tiden
The aim of this paper is exploring questions regarding the problem of absenteeism among high-school students in Sweden. Fifteen students attending an urban high-school have been interviewed about their views and experiences of absenteeism. The author analyzes the students? answers by taking into account two different sociological approaches which give two different explanations about the way young people experience and estimate education. The French sociologist Bourdieu theorized that differences in cultural capital influence the permanent internalization of patterns of thought and behavior.
Forensisk analys av volatilt minne från operativsystemet OS X
Behovet av att analysera volatilt minne från Macintosh-datorer med OS X har blivit allt mer betydelsefull på grund av att deras datorer blivit allt populärare och att volatil minnesanalysering blivit en allt viktigare del i en IT-forensikers arbete. Anledningen till att volatil minnesanalysering blivit allt viktigare är för att det går att finna viktig information som inte finns lagrad permanent på datorns interna hårddisk. Problemet som låg till grunden för det här examensarbetet var att det uppenbart fanns brist på undersökningsmetoder av det volatila minnet för Mac-datorer med OS X.Syftet med detta arbete var därför att undersöka möjligheten att utvinna information från ett volatilt minne från en Mac-dator med OS X genom att kartlägga och bedöma olika undersökningsmetoder. För att göra denna undersökning har litteraturstudier, informella intervjuer, egna kunskaper och praktiska försök genomförts.Slutsatsen blev att möjligheten att utvinna information från det volatila minnet från en Mac-dator med OS X är relativt begränsad. Det största problemet är själva dumpningen av minnet.
Långtidsfrisk eller arbetsglädje - vad speglar arbetsrelaterad hälsa?
The work related illness has increased and instead of focusing on what?s causing it more and more efforts are put on trying to find the health factors within and outside the work environment. During the past years the term ?long-term health? has arisen; instead of focusing on the number of employees on the sick-list, the focus should be put on the number of employees that has a record of long-term health within an organization, i.e. health-presence.
Begärets erotiska identitet : Queera tendenser i språk och bild hos Marguerite Duras
The aim of this thesis has been to discuss whether remainders of colonial influences exist within the UN's definition of torture or not. The discussion has been presented from a postcolonial point of view, in dialogue with contemporary power critical theorists. In order to raise awareness of a potential colonial influence, the following questions were intended to be answered:? Are there any reasons, if so ? which ones, to regard the UN's definition of torture as a colonial project? And;? To what extent is the term ?inhumane? limiting for the prohibition against torture from a postcolonial perspective?One of the most central arguments of the chosen theories is that the term ?inhumane? evokes prejudices that a racializing apparatus within the social norms of the UN automatically produces. These prejudices are, according to the theorists, influenced by images of people in non-western and non-secular (especially muslim) societies as more prone to exercise ?violence? and ?cruelty? towards their own citizens as well as towards the population of the world in general.

Icke-farmakologiska metoder för behandling av beteendemässiga och psykiska symtom vid symtom demenssjukdom
ABSTRACTBackground: People with colorectal cancer undergoing rectum amputation get a permanent colostomy, which affects the social life. It may be valuable for health care what these people experience living with colostomy in order to provide the greatest possible support. Objective: The aim of this study is to describe how people who received a colostomy experience their daily lives and the support they have received from the health services.Method: Qualitative interview study with six people, with a descriptive phenomenological approach.Results: The analysis of the interviews about how it's like to live with a colostomy resulted in three themes: 1) Living with a colostomy gives an uncertainty that affect the social life, 2) Physical and psychological impact of getting a colostomy and 3) Support for health care and relatives.Conclusion: Subjects had a positive attitude towards life, which contributed to that they could adjust to living with a colostomy and feel a meaningfulness of life. The study shows that all the interviewed people overall were satisfied with the information provided by the healthcare personnel. It was good with both oral and written information and very appreciated with repeated information. One aspect that could be improved was the information given aboute the closure of anus during surgery and the following complications.

Kvinnor i chefspossitioner : - En studie studie om kvinnliga nyhetschefers arbetssituation i Mittmedia 2014
De senaste åren har den internationella turismen ökat explosionsartat och den förväntas fortsätta öka på samma vis. Detta medför både positiv och negativ påverkan på destinationen och för lokalbefolkningen. För att turismen skall vara långsiktigt hållbar är det viktigt att inbegripa turisternas perspektiv på destinationspåverkan. Tidigare forskning har främst varit fokuserad på lokalbefolkningens syn på turismen, och därför behövs vidare forskning från turisternas synvinkel.Föreliggande uppsats har som syfte att undersöka hur svenska turister uppfattar destinationspåverkan inom de tre hållbarhetssfärerna ekonomi, sociokultur och ekologi. Vidare syftar uppsatsen till att undersöka eventuella skillnader i upplevelser mellan de två turistgrupperna massturister och alternativturister.Undersökningen har gjorts med hjälp av en enkätundersökning administrerad på Internet.
