Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.

The purpose of this Masters thesis is to make an outline of different methods and theories within the field of bibliometrics and critically review their strengths and weaknesses. The author studied literature that discussed bibliometric methods and theories. The number of empirical studies that are based on bibliometric methods and theories are numerous and where principally excluded, but some empirical studies were included as part of the argumentation for and against different methods and theories. The author first gives an outline of which methods and theories there are and describes their different strengths and weaknesses. Citation analysis has many different fields of application such as information retrieval, mapping science, evaluative studies and monitoring literature.

Idag står vi inför utmaningen att leva inom vår planets gränser. För att uppnå en hållbar utveckling krävs det en förändring i tankesätt, värderingar och livsstil menar UNESCO-UNEP. Detta kan åstadkommas genom en fundamental förändring i utbildningen från tidig barndom. Syftet med den här studien är att undersöka hur hållbar utveckling tolkas i den svenska grundskolan. Två ämnen har valts; biologi och hem- och konsumentkunskap.

The subject of this master thesis is co-operation between archives, libraries and museums. The purpose is twofold: 1 To map out activities within the area to get an overall picture. The mapping is done by studies of documents and consists of international outlooks and an overview of national and regional projects and reports; 2 To investigate how leaders of the respective institutions within the various regions of Sweden apprehend co-operation between the three sectors. The empirical study is accomplished by inquiries and is mainly qualitative. An intermediate purpose of this essay is to try using grounded theory to treat and analyse the gathered material.

This thesis is about catastrophe tourism and the sustainability of the tourism in an environmental perspective. The purpose is to see if there is any interest for that kind of tourism and to see if the people who have an interest or curiosity of it thinks about the environment when they are traveling. A quantitative survey was made on the internet and people on Facebook, Resedagboken.se and Reseforum.se had the chance to answer it. There is an interest of catastrophe tourism and a few have been to catastrophe sites or would like to visit. The conclusion of the thesis is that there is a possibility of a sustainable catastrophe tourism because most of those who answered that they had or wanted to visit a catastrophe site also thought about the environment and cleaning up after themselves..

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Värdeflödesanalys är ett ofta använt verktyg inom förbättringskonceptet Lean och syftar till att eliminera slöserier i processer och erhålla en högre resurseffektivitet. Värdeflödesanalys har sitt ursprung i produktionssektorn men har utvecklats till att användas också inom tjänstesektorn även om det fortfarande inte tillämpas i lika stor utsträckning där. Reklamationsprocessen är just en sådan tjänsteprocess som detta examensarbete syftar till att undersöka.Målsättningen är att framlägga resultat som bidrar till att ABB Control Products kan lämna svar till kund inom 10 arbetsdagar från mottagande av returnerad produkt. För detta ändamål kartläggs ett antal avslutade reklamationsärenden bestående av produktfamiljerna kontaktorer, mjukstartare och tryckknappar. Dessutom följs ett mjukstartarfall i realtid genom reklamationsprocessen för att direkt kunna observera hur arbetet går till.Det kan konstateras att den främsta anledningen till att ledtiden för reklamationsärenden idag är för lång är att det samlas stora lager vid varje processteg.

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

Uppsala University Library owns eight volumes of manuscripts attributed to the academy equerry Johan Leven Ekelund (c.1701?1775). In this thesis, I apply methods from the field of material culture studies in order to establish which of the volumes that formed the donation from Leven to the library mentioned in his will. By mapping certain markers such as places, names and dates I am able to identify to some extent where Leven gained his practical skills and which writers influenced him. By analysing the texts, I draw the conclusion that the manuscripts can be divided into groups aimed for different audiences.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

The aim of this thesis is to investigate if an automation of the manual packaging process at Legosan AB is profitable.
