Resurseffektiv livsmedelsproduktion : Tillämpning av industriell symbios för ökad resurseffektivitet inom den svenska tomatodlingsbranschen

Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.

Slithållfastheten för dentin och cement i förhållande till emalj in vivo hos häst

The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

Hållbar Ö ? en analys av möjligheterna att försörja ett modellösamhälle i Stilla Havet med solel

The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic system that balances them against each other. The result from the model will then be used to calculate the electricity price per kWh for the island.The result of the work is that electricity from solar energy is comparable with electricity produced from oil, if the oil pays for all its external costs, and the potential for pumped hydro storage plants is located. It also requires that consumers of electricity can be their own producers to avoid the expenditure of tax and reducing the cost of distribution. But since oil is a finite resource and has had a rising cost in recent years, while solar energy has had a declining cost, perhaps this will be a more competitive solution in the future.

Översvämningsrisker längs Funboån

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.

Sista inlägget ? varför sluta blogga? : En studie av bloggare som avslutat sina bloggar

 By changing focus from the active blogger to the ex-blogger this study focuses on a part of the blogosphere that is generally overlooked, why bloggers stop blogging. 30 terminated blogs where studied and the ex-bloggers where contacted. Six main reasons why a blog is terminated was found: Changed life situation, The blog effecting private life, The blog effecting the professional life, Done with testing to blog, Blogging about an event, Done with the blog ? the logical termination. Outside the main focus of the study  it was also evident that most bloggers terminate a blog to put focus of one of their other blogs or start a new one.

Kvantitativ studie om knappsatsdesign och knappstorlekars påverkan på träffsäkerhet

A mobile testing application using Unity was developed to analyse what impact button sizes and button layouts has on the accuracy of touch as well as the time to finish a labyrinth. This was tested on a Nexus 4 phone. 28 users navigated a small object through a labyrinth in which they collect keys to open the door to the exit. Each participant did the test 6 times with different combinations of button size and button layout each time, done in a random order. Hits, misses, completion time, order of button size and order of button layout was collected and then visualized using R.

Alternativ till fortsatt elektrisk generering i Olidan

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Mannen och pappan : En filmanalytisk studie om hur män och pappor porträtteras i Tim Burtons filmer

I have with this thesis sought to understand how chick lit could be useful in the classroom in the teaching of Swedish B-course in high school. Based on the model of critical literacy I am arguing that this genre would help to meet the objectives of the policy documents which, among other things, are to critically examine and analyze various types of texts.I have found that some of these texts could be used for analyzing and critically examine the ideological dimensions of texts and cultural heritage by the model of critical literacy, and also as a counterweight to the more traditional teaching of the canonical literature as a literary historical stuff that students should learn. I have also wanted to create a basis for discussions about literature in the classroom based on the chick lit genre. To do this I have, based on three themes and questions from the model of critical literacy, tried to focus on issues that might emerge from the ideological analysis and critical review. The model aims to deconstruct norms of society, and in the work of chick lit, I wanted to show how you could deconstruct norms around gender..

Simulering av översvämningar i Byälven

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

HAVECA-modellen - En metod för att fortlöpande säkra ett internt nätverk mot tredjepart

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

A further aim is also to investigate the possible factors influencing information seeking in relation to everyday life for international students. Interviews were carried out with eight international students, 20-35 years old from three continents. They were to stay in Sweden for at least five months for the purpose of studying.

Navigationshjälpmedel i tredimensionella virtuella miljöer och understödjande av minne

This thesis explores different ways of navigation in virtual environments. It also investigates how virtual environments can support human memory. Tests are done using a self made virtual model of Orkanen Library, Malmö högskolas school library. Among the different navigation tests that were done, a visual guidance in form of a line on the ground leading to the goal is showed superior when navigating a virtual environment but that people prefer legible landmarks instead. Tests were also done which show that a 3D-model of a real location supports context based memory.

Finns det skillnader i livskvalitet och livstillfredsställelse mellan frivilligt barnlösa och föräldrar? : En kvantitativ tvärsnittsstudie

Studier har visat att frivilligt barnlösa individer stereotypt har betraktats vara olyckliga och otillfredsställda, något som inte har fått vetenskapligt stöd. Syftet med den här tvärsnittsstudien var att undersöka om det föreligger några skillnader i livskvalitet och livstillfredsställelse mellan frivilligt barnlösa personer och föräldrar i den svenska populationen. Forskningsfrågan undersöktes med en enkät som bestod av självskattningsskalorna QOLI (Quality Of Life Inventory) och SWLS (Satisfaction With Life Scale). 130 deltagare genomförde studien varav 54 är frivilligt barnlösa individer och 76 är föräldrar. Studien visade att det inte finns några signifikanta skillnader mellan grupperna med avseende på livskvalitet och livstillfredsställelse.

Presentation av en marknadsföringsmodell för folkbibliotek

The purpose of this thesis is to construct a marketing model to be used both theoretically and practically when working with marketing in Swedish public libraries. This objective is achieved by first making a literature review of the written works on the marketing of libraries, and then studying the marketing activities at the public library in Bollebygd, Sweden. The theory is based on the marketing mix model the 7 ps, which serves as a framework for the presentation of the empirical result and the analysis. One of the questions posed in the beginning of the paper is how the library has worked with marketing over the past ten years. Through a combination of methods observation, textual studies and interviews the marketing activities employed at Bollebygds library are noted.
