The aim of this study was to find out how journalism students at two universities in Sweden, Gothenburg University and Linnaeus University in Kalmar, use the social networking service Twitter. We were primarily interested in whether the students are using Twitter as a journalistic tool, which includes gathering, production and distribution of material. The study focused on journalism students because they soon will enter the working life and therefore can provide an indication of whether Twitter is a part of the future of journalism. We have used theories of mass communication to describe the development in the area and explore how journalism has adapted to this change. The study was conducted in the form of a survey in which the students answered questions about how they use Twitter and what they think about the social networking service.

Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.

There's no doubt today that mankind has contributed to the changing climate byher use of fossil fuels. This must change in the nearby future. The Europeanleaders are expressing concern that renewable energy sources are not beingused to their full potential. The 2001/77/EC Directive on Electricity Productionfrom Renewable Energy Sources was accepted in 2001 to encourage thedevelopment of energy production from renewable sources, which isconsidered a step towards the fulfillment of the goal of the Union, that 12% ofthe gross energy consumption should come from renewable energy sources bythe year 2010.The objective of this thesis is to illuminate the common legislation of the EUregarding renewable energy with regard to goal fulfillment, judicial quality,conflicts with other goals of the EU and other faults. The objective is reachedby a hermeneutic study in which interpretation of written text is the mainmethod.

Följande rapport är resultatet av det examensarbete som utförts våren 2011 inom innovativ produktion/logistik vid Mälardalens Högskola. Examensarbete behandlar ämnet Green Production med fokus på skillnader mellan ett produktionssystem som bygger på Lean Production och ett som bygger på Green Production. Områden som berörs i rapporten är de verktyg som används i de olika produktionssystemen, hur arbetet med miljöförbättrande åtgärder kan se ut i praktiken samt vilka svårigheter som finns vid arbete med miljöförbättrande åtgärder i ett företag. Examensarbetet består av en litteraturstudie där aktuell litteratur studerats inom området samt en intervjustudie som genomförts med insatta inom miljöfrågor kopplat till produktion samt operatörer.Bakgrunden till examensarbetet grundar sig i att världen står inför en framtid där många utav de råmaterial som används idag vid produktion inte kommer att kunna nyttjas i framtiden. Detta i kombination med de miljöproblem som människan åsamkat, har bidragit till att många företag insett att miljöaspekter måste vara i åtanke genom hela produktionsprocessen.Den uppfattning som erhållits genom intervjustudierna är att det är viktigt för ett företag att visa att de arbetar med miljöförbättrande åtgärder.

The purpose of this essay is to examine how officials within the Swedish public libraryorganisation view the IT-development, how the IT-development progresses within theorganisation and if there is a need for a national IT-strategy for the public libraries in Sweden.Four unorganized interviews with officials within the regional- and county libraryorganisation and one within the national organisation where conducted. This study is aqualitative examination where the phenomenographic approach has been used as inspirationfor the analytic model. The analytic result has been compared to the system theory of how anoptimal system should be constructed to perform in an optimal way and to be able to producegood results. The results of this study show a wish for a better national cooperation regardingthe IT-development for the Swedish public libraries. Today?s library structure should bereviewed over in order to enable the libraries to produce even better results from the cooperation?s..

Several technical solutions are ready to step forward as the new generation of propellant, and this report aims to explore the possibility of commercializing fuel cell cars. The report is based on current research and data from today's technology and engineering solutions that are estimated to be commercially realized before 2020.A mapping of today?s different fuel cell options has shown that the most suitable fuel cell option is the Proton Exchange Membrane Fuel Cell, which uses hydrogen as fuel. The report is focusing on a techno-economic well-to-wheel analysis of hydrogen and the energy balance and costs in a system perspective. The basis for this analysis consists of two centralized methods of production, steam methane reforming (SMR), and alkaline water electrolysis.

The production of cheese is in continuous development with objectives to in-crease productivity, achieve changes in shelf life and functional properties of the products. One concept in the development is to substitute milk fat with vegetable fats and oils in the manufacture of cheese. The objective of this study was to investigate effects on cheese yield and cheese quality of 4 different semi-hard analogue cheese products produced by substituting milk fat with vegetable fat, each analogue cheese with a specific mixture of vegeta-ble fat. As reference a cheese produced with anhydrous milk fat was used. The yield and recovery of fat and protein were determined by recording the weights of each cheese direct after press and after 20±2 days of storage and analysis of the composition of the cheeses after 20±2 days of storage. The cheese was fur-ther subjected for texture profile analysis in a TA-XT Plus Texture Analyser and analysed with Differential Scanning Calorimetry (DSC) to examine whether the fat behaves similar in the cheese as in pure form in respect to its thermal properties. The cheese yield was not significantly different when using different fats. Differ-ent amounts of water were absorbed during the water cooling.

Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.

This essay has examined how the local community is involved with the tourism development on the San Blas islands and how it effects the destinations development. The method of choice has been a qualitative interview with an operator that offers trips to the destination. Also there has been made a literature study where previous research about the San Blas and the subjects of choice is being presented. During the writing process of this essay it has become obvious to us that the local community (Kuna Yala) is very much involved in everything that concerns the destination. We can thereby establish that the local community of San Blas can be placed on the top step of Arnsteins (1969) ?Ladder of Participation?.

The retail sector is in a continuous development. What demand looks like and where the consumers want to shop has changed during the last years. Market place, demand, supply, external factors and politics affect how the retail sector develops. To make a market place attractive a variety of factors have to be considered.In Hong Kong a model called Rail & Property is used, this means that the development of the subway is integrated with the development of the city. The model is both successful and economically sustainable.Today the supply of shops and services in Stockholm´s subway stations is rather small.

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

This exam report has been developed in association with Strangbetong AB, Sweden.The natural gravel that is being used as fine aggregate for concrete production today is an ending natural recourse and the Swedish government has decided to strongly reduce the extraction from the year of 2020. The only reasonable replacement is aggregates from crushed rocks but this material has other properties than natural aggregates. The concrete manufacturers now have to learn how to use these new fine aggregates in a cost effective way in order to ensure the quality of their concrete production.In this project, crushed aggregates and combination of crushed and natural aggregates have been tested with existing formulas for fresh concrete. The two parameters yield stress and plastic viscosity have been measured which gives a good description of the workability of the fresh concrete. Different methods to make measurements on the dry fine aggregates, has also been tested, to find out if there is any correlations between these parameters and the parameters from the measurement on the fresh concrete..

This master thesis is about the collaboration between the custom dairy heifer grower and thedairy producer.The custom dairy heifer grower is a rather unusual strategy of reproductive management inSweden compared to other countries like U.S. and Denmark where the specialization withindairy production gone much further. In these countries the research also has reached muchfurther within this type of industry. However in Sweden there has been research made in thearea of collaboration, but then only within collaborations in the industries of crop production,dairy production and pork meat.The down going trend of profitability within dairy production together with poor profitabilityin the beef industry could partly remedy if more collaborations around heifer contractingwould arise. But since the industry still is of a rare kind in Sweden the knowledge about howthese types of collaborative arrangements works and their contracts are put together is poor.By that the aim of this master thesis is formulated as follows: "how is usually thecollaborative arrangement between the dairy producer and custom dairy heifer growerdesigned".

To invent an optimized product is a complicated process. This process is only half of the work. It is equally important to develop a production system that can produce the product in an  efficient and ergonomic way.After several evaluations of conceptual and detailed drawings a final idea has come to light.The idea intends, to the maximum extent, utilize the facility in a more efficient way through moving assembly lines and stations closer to the flock section and the stock for complete products. To make the production better, stations are placed in more logical places given the assignment they are supposed to accomplish. This improves the material flow radically.
