Open ecosystems, such as grasslands and pastures, have naturally been shaped by disturbances like fire and grazing. These processes play a crucial role in creating habitats with high biological diversity, particularly favourable for a wide range of herbaceous plant species. In recent years, many of these disturbances have ceased, leading to encroachment, fragmentation and habitat loss. The aim of this study was to examine and compare the effects of fire, herbivory and a combination of fire and herbivory on the emergence of herbaceous plants. The study was conducted at the Ecopark at Nordens Ark.

The purpose of this MSc thesis is to examine the retrieval effectiveness of two Web search engines with queries from the academic discipline of Classical Studies. The two search engines are chosen to represent two different types Google as a broad general search engine and Argos as a specialised search engine for the subject of Classical Studies. The search engines are compared for precision among the first twenty results returned for thirty queries. In order to avoid bias in the study, the queries are based on real users' information needs. Due to the subjective character of the concept of relevance, the study is performed with five different experiments with five different definitions of relevance.

Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made. Just over one fifth of the blogs are linkted to each other in one big network, where the remaining blogs stand without any ingoing or outgoing links.

Most of the saw and pulp industries have stored wood nearby their production, the main reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality. One drawback of wet storage of wood is the leaching of chemical substances into the surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and organic substances. These substances can cause problems for the surrounding environment. The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.

Earlier research has shown that generational differences between younger-supervisors and older-workers may cause tensions that lead to team ineffectiveness. There is however still a lack of research in this area. This thesis presents possible tensions that might occur between a younger supervisor and an older worker due to their age and generational affiliation, and how these tensions affect the team dynamics. The empirical data collection was limited to the boundaries of the dental care industry where these generational/age differences between younger supervisor and older worker are common. The thesis looks at the tensions from a qualitative perspective and data was collected in the form of in-depth interviews with selected dentists and nurses.

Denna rapport jämför ett kommersiellt site survey-verktyg med ett open sourcealternativ.En site survey är processen att planera och implementera ett trådlöstnätverk. Det är viktigt för att undvika problem med täckning, störningar samtplacering och konfigurering av accesspunkter.För att göra jämförelsen har en metod utvecklats för att jämföra site survey-verktyg. Metoden tar upp och jämför olika kriterier i form av verktygens förmåga att hantera signalstyrka, störningar, quality of service, manuella site surveys, virtuella site surveys, dokumentering av resultat samt verktygens förmåga att underlätta vid placering och konfigurering av accesspunkter. Förutom detta tas även mjukvarornas gränssnitt och användarvänlighet upp. Metoden skulle dock kunna utökas ytterligare för att innefatta t ex säkerhet, inlärningstid och support, för att på så sätt bidra till en bättre jämförelse.De verktyg som har jämförts är open source-mjukvaran Kismet och den kommersiella mjukvaran InterpretAir.InterpretAir har visat sig ha en bättre funktionalitet på alla punkter och anses därför vara den mest lämpliga mjukvaran vid en site survey.

For centuries Islam and Muslims have been subject to islamophobic attitudes in the west. The purpose with this study was to see into the making of open and closed attitudes against Islam and Muslims from a conflict in southern Thailand, and also to so see if Muslims are portrayed as more violent than the Buddhist groups in the conflict. The aim of the study is also to see if Muslims fall into a violent stereotype. This was studied by looking at five Swedish newspapers coverage of the conflict, during a given time. To be able to look into this, two theories will be used, the first one is the Runnymede Trust theory, which is about open and closed attitudes against Islam and Muslims.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.

Klättring är en växande sport som kräver jämn balans av styrka, teknik och psyke. I dagslägetsker klättertävlingar och de hårdaste utomhuslederna på branta överhängande väggar med smågrepp. God fingerstyrka är nödvändigt att ha när klättring utövas för att kunna hålla sig kvar igreppen, som består av lister, på väggen. Då dessa lister tas används en greppteknik somkallas för crimpteknik. Det går att hålla i listen i denna teknik med tre olika positioner, closedcrimp, open crimp och open hand.Syftet med denna studie är att kartlägga skillnader mellan olika test av prestationsförmåga ochcrimputhållighet, undersöka vilken crimpposition som går att hänga längst i samt utforskakorrelationen hängtid i crimp med styrkeövningar.Tjugotvå manliga klättrare rekryterades och indelades efter inrapporterat personbästa i tregrupper (elit, avancerad och normal).

This study takes place within a publicly owned art producing organization and dwells on the problems of a change process that the organization was involved in. Both leaders and staff were disappointed by the way the change process had developed. The management team explained the outcome by referring to the uniqueness of working with artists who constantly put their own personal objectives before the benefit of the whole. The aim of this study is to find a complementary explanation to the one the management team provided us with; an explanation that can help in the understanding of the dynamics of a change process. Can perhaps theories on information, communication and change processes give an alternative explanation to why the change process faltered? To investigate this, we have used a qualitative single case study.

"Speak up! I can?t hear you"This qualitative study is built on an investigation of a newly instated model that is used when building or renovating schools. The principles of the model are based on building schools with an open plan design where the walls are made of glass and the classrooms are not shut closed by walls, instead the classrooms are completely open except from screens that are used to indicate the ambit of the rooms. This model has been well debated and that is the reason why we chose to do this study.The purpose of this study is to find out how students and teachers experience this model. To do this we have done interviews and observations.

The review of Integrated green spaces in urban areas ? A case study of inner Brisbane highlight the significance of addressing characteristics, qualities and landscape values in our outdoor environment. The importance of green spaces to the wellbeing of people in the city and the ecological, social and cultural values they carry are widely recognised in the field of urban and regional planning. At the same time population growth, climate change and urban development put planners and scientists in a challenging position where new solutions must be put on the agenda in order to accomplish sustainability. Open space strategies, collaboration between stakeholders, public participation, learn from earlier failings and a ?value-led? approach facilitate the managing of open space. Brisbane is located in the fastest growing metropolitan region in Australia. The city´s open space landscapes offer cultural, geographical, recreational, social and scenic amenity assets, which make a major contribution to the regions identity they a wide world known for.
