The purpose of this thesis is to examine the usability of the Umeå University library catalogue Album. The aim is to evaluate the catalogue in order to establish if there are any problems that could be solved by modifying the catalogue. The following questions are answered: How should a good catalogue be designed? Which problems are common when using a library catalogue? Is Album user friendly? Are there any problems that occur when using Album and how can the catalogue be changed to avoid the problems? To answer these questions I have performed a usability test in which five persons, all students, got to carry out twenty tasks in the catalogue and talk about what they were doing and thinking while doing the test. This method is a usability method called Think Aloud.

SAMMANFATTNING Läkemedelsresistens är ett växande globalt problem. Inte minst bland parasiter hos våra djur har rapporter om utebliven effekt av läkemedel ökat. Pålitliga detektionsmetoder av anthelmintikaresistens hos nematoder är viktig så att åtgärder sätts in i ett tidigt skede för att djurvälfärd och produktion ej försämras. Detta kräver standardiserade och beprövade detektionsmetoder. De metoder som används idag för flertalet nematoder är ursprungligen framtagna och anpassade för strongylider hos får.

Technology evolves quickly, with innovative ideas growing everywhere. Still, no technology is anywhere near challenging the mouse and keyboard for navigation of your standard computer. This study focuses on comparing the traditional technologies of mouse and keyboard with the new technology of gestures - in this case Leap Motion - in purpose of finding how the usage differs and what the potential users want from the competing technology. The experiment was executed in a controlled environment, with as few external factors as possible. We found that although the test subjects found Leap Motion fun, the test subjects do not want to surf the web with gestures.

It is well proven that physical exercise has an impact on our bodies as well as our minds. The aim of this study is to examine if this impact also affects economic behaviour. Three hypotheses regarding the impact of acute exercise on overconfidence, risk enhancement and well-being have been tested by collecting questionnaires from 364 participants at Friskis & Svettis, Kungsholmen who all were asked to answer the questions either before or after exercising. The differences between the before and after group were analysed, indicating small increases in all three test areas after exercising. These increases were, however, not large enough to reject any of the null-hypotheses of zero effect on the given five per cent significance level.

ÅF Test Center in Borlänge had a need to expand their capacity for compressive and tensile strength tests. They wanted to do this by using a hydraulic cylinder, which they already possessed, to apply the force with. This required a load receiving structure. The aim of this work was to design and dimensioning a test bench for a cylinder marked NIKE 300 tons. The work would result in a completed design proposal on a test bench which could manage to run the compressive and tensile strength tests of up to 3000 kN.

Swedish students' knowledge of both mathematics and reading comprehension has deteriorated in recent years. Scientists are discussing whether there is a connection between these areas and that the pupils deteriorating math skills may have something to do with their increasingly lower results in terms of reading comprehension. To investigate this possible connection, I conducted a survey among students in ninth grade and have come to the conclusion that the scientists are right: this connection absolutely exist. Students who received a high score on tasks designed to test students' mathematical problem-solving skills, also received high results on the reading comprehension test. And students who received a poor performance on the problem-solving tasks, were also low performers in the reading comprehension test.

Nathalia Edenmont is a controversial and uncompromising photo artist who has caused the whole world to rage over her obscene photographs. In this thesis I have researched Edenmonts artistry with help of the sociologist Pierre Bourdieus field analysis. By using Bourdieus's different field concepts I have researched Edenmonts artistic career by concepts such as habitus, consecration and different principles.The starting point of this research has been that Nathalia Edenmont is in the autonomous artistic field. I give examples of images that have been highly debated and I have collected information of how Edenmont sees her own images and her artistry. In this thesis I show amongst other things an example with Edenmonts photograph of dead rabbits with Elizabethan hair styling, cut up mice that work like finger puppets and children who are bound up in wire.Nathalia Edenmont autonomous artistry is deeply rooted in her background and the environment in which she was raised.

During the last couple of years it has been more important to reduce the driving on the field to prepair the soil after ploughing. The machine costs are high so it is necessary to be effective. To reach a pleasant soilbed directly after ploughing is sometimes possible on easier soils but heavier clay soils always need more tillages. There is a lot of equipment mounted on the ploughs on the market, for example Furrow Cracker and Furrow presses, which makes a pleasant soilbed on easier soils. The last year Överum and Kverneland have presented knives which are mounted on the wing or moulboard.

The worldwide industrial demand of energy, often in form of fossil fuel, is continuously growing and at the same time these resources are coming to an end (Hamamre, 2013). The interest and focus in renewable sources are then more important than ever and plants are suggested to be a good alternative for production of raw material for industrial purposes (Nilsson et al., 1998). But the world is also facing an increasing world population which also increase the nutritional needs, plants therefore need to be suitable for both industrial and nutritional purposes. To achieve this, common plants need to be improved but it also need new potential crops to be developed and introduced (Carlsson et al., 2009). Modern technology like gene engineering is an important tool to achieve these challenges (Carlsson et al., 2011). This work focused on analyzes and evaluation of different transgenic lines of field pepperweed (Lepidium campestre L.).

I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.

Syfte: Studiens syfte var att jämföra resultaten vid mätning av motorisk och sensorisk ögondominans med hjälp av ett test ur vardera kategori, för att undersöka om dessa ger samma resultat och därför kan anses likvärdiga vid mätning av ögondominans. Metod: Två olika dominanstest utfördes på 30 stycken testdeltagare i åldrarna 21-32 år vilka alla hade samsyn och balanserad visus mellan ögonen. +1D test användes för att mäta den sensoriska dominansen (ögonprevalensen) och håltestet användes för att mäta den motoriska dominansen. Dessa test valdes då de är frekvent använda bland optiker idag, och då deras utförande kräver minimalt med utrustning.Resultat: 73,3% av deltagarna uppvisade samma dominans enligt båda testen, 13,3% uppvisade olika dominans vid mätning av båda testen och resterande 13,3% uppvisade dominans för håltestet men icke dominans för +1D testet.Slutsats: Jämförelsen mellan håltest och +1D test visade en korrelation på 73%, varför de kan anses vara statistiskt korrelerade. Denna höga korrelation medför att dessa två tester därför kan anses jämförbara vid mätning av ögondominans. .

Många hushåll och individer har i dagens samhälle tvingats börja pendla till sina arbeten bl.a. på grund av en förändrad arbetsmarknad. Syftet med föreliggande studie var att se om individer som pendlar regelbundet har ett lägre KASAM. Utgångspunkten var att individer med en mer extern kontrollokus ofta har lägre KASAM och att pendling hypotetiskt sett bör påverka individen lokus i en extern riktning. Sammanlagt 27 försökspersoner i åldrarna 22 ? 50 år undersöktes med hjälp av KASAM test och I-E test.

How can the object based art help us, as viewers and as makers, to access a supplanted emotional state?One way of positioning yourself within the corpus-field is to step outside the traditional borders of the field and aim for other values within the objects, such as a visible working process, a storytelling or an emotional relationship to the object.  It is a way of taking a step from the traditional silversmithing towards some kind of free undefined corpus-art.  To reach for suppressed feelings is one way to find an importance within the artistic work, to give it a purpose.By investigating the concept of the sublime and the surrealist movement I try to find examples on how you, both as a viewer and as a maker, can put yourself in an emotional/intuitive state.  Through interviews with Jewellery and corpus artists I get a maker?s perspective which I compare with my own reactions to their work.Works of art can be used as a catalyst to reach, and maybe also to process, unattended feelings. This creates a strong emotional connection to the work.  As a maker you can, for example, do this by working with it as a theme, or by using an intuitive working method.

The purpose of this essay is to examine the development of the use of private securitycontractors in Iraq. The reason is that there has been a considerable increase of the number ofprivate security firms operating in Iraq during the last couple of years. The legislation in thefield of private military and security is indistinct and my hypothesis is that the lack of nationaland/or international legislation can be connected to the increased globalization. To come toany conclusions about this I have chosen to make a comparative study between the two casesthe Gulf War and the War in Iraq which started in 2003. In this comparison, I ask thefollowing questions: 1) Are there any signs of anarchy in the field of private security duringthe Gulf War respectively the last War in Iraq? 2) In what way has the use of private securitycontractors changed from Case 1 to Case 2 ?According to my research, there were signs of anarchy in the field of private security bothduring the Gulf War and during the latest war in Iraq.
