In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

The aim of this Master?s thesis is to examine the image of the man in Swedish crime fiction. Gender theory based uponRobert W. Connell theoretical framework which discusses masculinities in plural is used. The method used is idea analysis and my supply for analyse is constructed on thebasis of Connell?s four ideal types regarding masculinity.The material in the investigation comprises of five novels published in Sweden 2007.The investigation reveals the complexity in forming masculinities; traditional male values remain mostly intact, but at the same time men must deal with emotions andrelations with women in a world where the male norm often is questioned.

Dione kullager AB is a company in Uppsala, which sell industrialmachinecomponents, transmissionsolutions and provides repair serviceof hydraulic components.When a hydraulic cylinder is about tobe repaired it needs to bedisassembled. Because hydrauliccylinders usually work in dirtyenvironments and are heavilyworn some types of cylinders arealmost impossible to disassemble.Today the disassemble is made by hand,which means extra work for themechanics. In order to facilitate thedismantling of this type of cylindersa machine is to be developed for thispurpose and this is where this thesisbegins.The thesis has been organized in threephases: Literature study in whichfacts and theories are acquired.Concept generation in which differentconcepts, calculations, and solutionswere identified and selected. Thedesign phase where all the differentconcepts of components were assembledand simulated in SolidWorks. Similarstructures have also been studied inorder to identify necessary functions.The thesis resulted in a structurewhich is believed to meet therequirements.

Modern methods for managing pine (Pinus sylvestris) create homogenized forests. This decreases nature?s potential for biodiversity and might threaten species in need of different types of milieu. The main purpose of this study was to investigate how important older pine trees are for biodiversity. In the Hall-Hangvar Reserve in the north-west part of Gotland, insects collected from traps showed that more species were found in old or dead trees compared to younger pine trees.

This report discusses the constructionof different types of exterior wallconstructions and analyses wall layers.Standard wall constructions from theSwedish building contractors NCC andSkanska and also from the materialproducer Isover have been chosen for theresearch. Life cycle cost analysis hasbeen made to conclude the mostprofitable wall type, seen from asustainable and economic perspective.The calculations have been made for aperiod of 50 years.The report shows that building with wellinsulated walls is a more profitablesolution both economically and whatconcerns sustainability even though thehigher investment. However, when wallssimilar insulation properties are beingcompared, the study proves that lowerinvestment cost is more profitable.The report introduces requiredconstruction techniques of walls inorder that the reader should understandwall constructions with different layersand properties. The essay shows theimportance of properly constructed wallsto avoid air leakage and moisturedamage.The essay has been implemented byliterature studies, contacts with NCCand Skanska and by energy calculationsmade by hand and using the software VIPEnergy..

The tablet is a new IT-tool which have started to get introduced into school, but research is still missing and especially in the pre-school environment. The purpose with this study is to investigate teachers uptake, how they use the tablet in everyday pedagogy work as well as the organizational conditions that that facilitate and hinders. Through my observations and interviews in a Swedish K-5 school I have found that the teachers find tablets more appealing to use in comparison to computers. These findings are partly supported by Davis et al.?s (1989) TAM-theory who considers there to be three types of aspects that affect the way individuals adapt to technology.

When the producers? responsibility for packaging was introduced in Sweden in 1994 the industry set up public recycling stations to facilitate the collection of the waste material. In order to establish recycling stations at suitable locations the municipalities assist the industry?s service organization for operation of the recycling stations, the Package and Newspaper Collection Service (Förpacknings- och tidningsinsamlingen, FTI). The objectives of this thesis are to improve the service of the public recycling stations within Lidingö town and to increase the accessibility to these stations for the inhabitants of Lidingö.

Background and research problem: The former highly inflationary property market is currently undergoing a stagnation process. Investors have been used to annual growth figures in double digits,but now this is no longer considered to be a realistic outlook for future years. According to a report from PriceWaterhouseCoopers and Urban Land Institute, published by Avanza Wealth Management,the three most attractive markets for property investment in Europe are London, Paris and Stockholm. Because of this the authors have focused their investigation on two companies in the London andStockholm. The authors will additionally use an international bank, an estate agent and a consultancy firm for further information, with regards to the property market and risks associated with these typesof investment in particular.

When Swedish authorities are to purchase or rent something, public procurement is used as a means to an end. Authorities as well as suppliers are subjects to the fact that Swedish law regarding public procurement regulates the form of procurement in one set of particular regulations (LOU) and the form of contracts in another set of general regulations (AvtL). Suppliers and purchasing authorities close a contract regarding the subject of procurement and the law of public procurement regulates when such a contract can be closed, simultaneously the law of contracts regulates when parties are held to contracts and when contracts are to be rescinded. I investigate in this essay what these two types of regulations can result in for the contracting parties. As it is today agreements that have been entered into wrongfully still are valid, even if a court of law nullifies the procurement and sentences the purchasing authority to make a new public procurement.

The aim of this thesis is to examine the existence and prevalence of earnings management in Swedish companies. Theoretical frameworks often suggest that there are strong incentives to practice earnings management. The research area of earnings management has, to date, mainly focused on detecting earnings management. However, to our knowledge, no such studies have been conducted on Swedish companies. This thesis provides evidence of the existence and prevalence of earnings management in Swedish companies.

This bachelor's thesis is a study of operative approach and attitude to espaliered fruit trees in home gardens. Through qualitative interviews the informants give their view of problems which might arise, and to some extent how the problems can be solved. In addition, which benefit can be obtained from growing these different types of trained trees and for whom they might be suitable. Thematic analyses were used to find themes and patterns for deeper understanding. The conclusion was that these kinds of trees would be beneficial to use to a greater extent than is done today you can use more species and varieties, fit more trees in a small garden, and enhance the trees esthetical appearance.
