Det är dit man går om man ska söka information. Skolbibliotekets roll i gymnasieelevers informationssökning
The aim of this thesis is to examine how high school students use their school library for their information-seeking. The theoretical framework is based on Louise Limbergs three categories of students views on information-seeking and Andrew Large and Jamshid Beheshtis three categories of students choice of information systems. Qualitative interviews were used and seven high school students were interviewed. The empirical material was compared and divided into 9 categories. The results show that the students see the school library as a place where they can search for information, but its also considered to be a good place to hang out between lessons to study or to meet friends.
Förvärv och förvaltning av hyreshus - En utredning av de nya lagstiftningarnas tillämpning
In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer
Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.
Utvärdering av strömmätningar vid Höga Kusten : Strömmars betydelse för lokalisering av odlingslokaler och utformning av kontrollprogram i kustområden
A study was made to evaluate how current measurementscould help to determine how particles from fish farms are dispersed. During sixweeks of the summer 2012, two different current measurements were conducted.One of them consisted of measurements each fifth minute at 5 m and 15 m atthree locations for 14-16 days each. The other consisted of profilemeasurements at each location at four times during the period of six weeks. Forthe current measurements two instruments (model RCM 9) were used. A two weekmeasurement can give enough data to make an evaluation of how the currents at alocation will transport litter from a fish farm.

Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
Skyltfönstrets möjligheter - En kvantitativ studie om skyltfönster baserad på kreativitet och tid -
Store windows, as many earlier research studies indicate, is an important factor of the store atmosphere to attract customers into the store. In this study we have narrowed it down and chosen to focus on how different contexts of the store windows will effect customers' evaluation. The purpose is to find out how the context of high creativity and low creativity combined with different time aspect in store windows will affect store image, attitude, entering decisions and purchase intention toward the store. The results are based on a quantitative study where we did an experiment and a field study. The result shows that higher level of creativity is better than lower level of creativity in certain aspects.
Lättläst eller inte? : En läromedelsanalys av lättlästa läroböcker, inom ämnet svenska, anpassade för elever med läs- och skrivsvårigheter
The demands on the adult literacy-rate are very high in Sweden. People with reading and writing difficulties may find it hard to fit into the community and to succeed in school. To accommodate the needs of students with learning disabilities, Swedish schools provide easy-to-understand materials. The purpose of my thesis is to examine how easy-to-read textbooks for high school students are different from regular textbooks. The study was carried out using a content analysis and I examined the books according to criteria specified by the Swedish author Torbjörn Lundgren.

Full Circle: upstream and downstream migration of Atlantic salmon (Salmo salar) in the northern Swedish river Vindelälven
The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.

Svensk-Finsk marin interoperabilitet inför ett fördjupat försvarssamarbete : En jämförelse av Sveriges och Finlands militärstrategiska koncept ur en marin synvinkel
A decision has been made that the Swedish and the Finnish Navy will expand their cooperation by creating the ?Swedish-Finnish Naval Task Group? (SFNTG).Based on Michael Codner?s theory of interoperability, this essay?s aim is to investigate if the Swedish and the Finnish currently are interoperable with each other, due to their military strategic concepts.According to Codner, similarities between the cooperating nation?s military strategic concepts are required in order to reach a high degree of interoperability. This essay will analyze and compare Sweden and Finland?s military strategic concepts, based on three categories; Global Projection, Territorial Defence and Combat Capability.The conclusion is that there are differences between the Swedish and the Finnish military strategic concepts in every category, of varying degrees. By looking at the results of this investigation, it is clear in what direction the two nations have to adapt their concepts to enable a high degree of interoperability for the future of the SFNTG..
