Den största delen av vår svenska kust gränsar till Östersjön, vilket gör att vi alla påverkas av dess miljötillstånd. Östersjön är ett förorenat innanhav med ett känsligt djur- och växtliv. Östersjön är redan, utan de antropogena föroreningarna, ett ogästvänligt habitat att leva i för både djur och växter. Detta beror delvis på att vattnet är bräckt och att arterna måste anpassa sig till dessa förhållanden, dels att det råder en naturlig syrebrist i vattnet. Även andra faktorer spelar in.

This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.

Holmen Paper is one of Sweden?s leading manufacturer of paper, with two Swedish production facilities located in Norrköping and Hallstavik. The European continent constitutes the company?s largest customer base which makes the company?s distribution system an integral part of the business. Historically, much of the produced paper has been transported by vessels, as vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.

International organizations are important actors on the stage of world politics, and how these actors securitize the climate change issue is of importance for how it will be tackled by actors on global and national levels. The purpose of this study is to contribute to research on climate security discourses and how climate change is defined as a security concern amongst different actors. This study, in contrast to previous research, focuses on systematically mapping the definitions made by different international organizations by asking: whose security is at stake; who is responsible for responding to the threat; how is the nature of the threat defined; and what responses are suggested? By analyzing material consisting of a variety of documents and statements from five international organizations, I aim to identify differences between these actors ? in how the climate change issue is conceptualized from a security perspective. The result of the study shows that only one of the organizations shows clear elements of the national/geopolitical security discourse, while all of the other actors primarily use the human security discourse.

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.

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.

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.

Naturbetesmarker är artrika och näringsfattiga habitat vars utbredning kraftigt har minskat under 1900-talet. Historiskt fyllde de en viktig funktion som fodermarker men har idag till stor del ersatts av åker och vallodling. Naturbetesmarker bör idag bevaras av andra syften, både biologiska och kulturella. De rymmer en stor mängd rödlistade arter och visar spår av historisk markanvändning. Många naturbetesmarker har tidigare varit betesmarker eller slåtterängar och när hävden upphör växer det öppna landskapet igen. I denna studie har effekterna av restaurering genom kraftig röjning och förnyat bete studerats.

Genom att undersöka begrepp som natur, det vilda och det sublima, i en idéhistorisk tillbakablick baserad i västerländsk kulturtradition, presenteras en ny möjlighet för efterbehandling av kalkstensbrottet Västra brottet i Slite på Gotland. En analys av platsen och tidigare nämnda begrepp leder till en förändring av det befintliga förslaget på efterbehandlingsplan. Denna aktuella efterbehandlingsplans tyngdpunkt ligger i införande av habitat. Förslaget i detta arbete är att en ?social efterbehandling? som har möjlighet att aktivera hela orten tillförs.

The countries in the European Union have agreed to increase their percentage renewable energy sources to 20 %. To reach this goal an increase of biomass production needs to be made. One way of achieving this is by using nonnative species. Poplar in Sweden produces biomass faster than the domestic trees. In the southern parts of Sweden plantations has been made with good results. In the northern parts survival is a problem that needs to be solved before plantations can be made for commercial use.

The aim of this thesis is to investigate if an automation of the manual packaging process at Legosan AB is profitable. Legosan AB, located in Kumla, performs subcontract work of dietary supplements and medical products to companies within Europe. The chapterportal robot is used in the other. As there are several options in the choice of packaging robot the suggestions of improvement are divided into two different designs. Other machines and equipment necessary for the different suggestions of improvement are showed and their measurements are presented.

Syftet med studien är att få en förståelse för hur utrustningseffektiviteten kan mätas i ett producerande företag. Vår studie utförs på ett företag i Alvesta som heter Gnutti Powertrain AB som bland annat tillverkar precisionskomponenter till motorer.Genom att vi skapar en analysmodell utifrån studerade teorier beskrivs ett systematiskt tillvägagångssätt som slutligen ska leda till att syftet uppnås. Utifrån analysmodellen studeras och beskrivs först Gnutti Powertrain AB´s nuvarande tillvägagångssätt för att sedan jämföras och analyseras gentemot de studerade teorierna. Med hjälp av analysmodellen struktureras också vår studie på företaget och vårt utförande och resultat utifrån detta kommer sedan att presenteras.Analysmodellen nämner att en processkartläggning först ska göras. I processkartläggningen väljs först en specifik process ut, vilken i vårt fall blev produktionsprocessen för en rulle av stål.

De flesta politiska riktlinjer har idag en hållbar samhällsutveckling som övergripande och gemensam nationell ambition. Det innebär att uppsatta mål för ekologisk, ekonomisk och social hållbarhet ska nås i samverkan mellan aktörer från olika sektorer och på olika beslutsnivåer. Att förstå vad det innebär på lokal och regional nivå, och hur man kan nå de målen, är inte så enkelt. Syftet med denna studie är att skapa ett underlag som kan användas i arbetet med hållbar landsbygdsutveckling, inom den informella regionen Bergslagen i Sverige. Hinder och möjligheter för hållbar landsbygdsutveckling har analyserats genom att arrangera fokusgruppdiskussioner med olika intressegrupper i samhället.

The purpose of zoos has changed over the decades. From being menageries where wealthy people showed their collections of exotic animals to today?s zoos where science, conservation and education has become a central part of their work. Education in zoos gives them the opportunity to spread the knowledge about ecology, biology and biodiversity to the general public. Their aim is to change the public?s attitudes towards our wildlife and raise awareness about the threats that exists against our planets biodiversity.
