Ödesstund för Europa : Om de geopolitiska konsekvenserna av Europas beroende av rysk energi

This is a tale about energy and power. It describes the geographer Halford Mackinder?s geopolitical theories and compares them with current views outlined by Zbigniew Brzezinski and Michael T Klare, among others. With a critical approach it also provides a historical account of a Europe that stands in front of an energy struggle so severe that the current world order seems destined to fall. Oil and natural gas, has since the beginning of the 20th century, been used as a geopolitical tool in order to create dependence, control and even sometimes overthrow empires.

Projektering för återupptagandeav elproduktion vid småskaligtvattenkraftverk

A small-scale power plant has more or less the samemaintenance costs as larger plants, but doesn?t generate as much income. Today?sincreasing price for electricity in combination with a desire for renewable energysources makes small-scale hydropower interesting again.

Learning Resource Centre (LRC) ? en bibliotekstrend?

Learning Resource Centre, or LRC, is an international phenomenon and a response to the changing society that came with the development of information technology. The LRC concept spread internationally during the 1990s and began to influence Swedish collage libraries at the end of the decade.

Metanol som marint bränsle : Alkohol som en lösning, inte ett problem

Sedan industrialismens start har människan påverkat klimatbalansen genom förbränning av fossila bränslen. Rökgasemissionerna förorsakade av internationell sjöfart kan inte tillskrivas någon särskild nations ansvar på grund av dess globala och komplicerade verksamhet. FN:s sjöfartsorgan IMO har således åtagit sig ansvaret att minska sjöfartens miljöpåverkan. Införandet av nya miljömål har resulterat i strängare globala och nationella regler som tvingar sjöfartsnäringen till omfattande anpassningar under kort tid. Som lösning för att uppfylla kommande krav gällande rökgasemissioner har flertalet alternativa bränslen diskuterats.

Fankultur på folkbibliotek ? ett redskap för delaktighet

The aim of this essay is to examine fan culture?s role in Swedish public libraries. I have interviewed, via email, six librarians who encounter and use fan culture in their daily work. The theoretical elements of my essay are based on a modified set of theories by Dorte Skot-Hansen that identifies six ideal types of cultural political rationalities. My study reveals that fan culture is used in Swedish libraries as a tool in increasing user participation in library activities.

Responsive web design : En studie i hur designkonceptet påverkar användbarheten hos en webbplats

The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.

Gränssnittsdesign för kundnöjdhet och administration

Kundnöjdhet är en stor inkomstkälla för företag. Det finns många sätt att mäta kundnöjdhet och ett av de nyaste sätten är genom en digital monter placerad i fysisk butik. Denna studie ämnar undersöka hur gränssnitt till en undersökningsapplikation skall utformas för att tilltala en bred målgrupp att lämna omdömen och hur ett användbart gränssnitt till den administrativa sidan för denna applikation kan utformas. Resultaten från utvärderingen av undersökningsgränssnittet visar att det finns designelement som tilltalar vissa användare mer än andra. Detta ger en fingervisning om hur design kan utformas för att vara tilltalande för användarna att lämna omdömen via teknisk plattform.

Gaspotentialen i en deponi, idag och i en framtid :

Deposited waste material degrades within a short period in anaerobic environments. The methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas. In this thesis the amount of produced methane gas at the landfill at Örebro has been calculated. Estimations have also been made of the amount of methane gas that might be produced in the landfill in the future.
