Skogen - vårt biologiska kulturarv
This article deals with the woodlands as a biological cultural heritage and how it is taken care of in the protected woodlands in Skåne, in the south of Sweden, especially the deciduous trees which is dominated by beech. High biological values have emerged as a result of grazing and different kinds of forestry. The protected woodlands have been ripped of its cultural influences which changes the biological values on which the original reasons for protection was founded..
Trafikverkets effektstyrningssystem - EFS 132 kV : Bidraget till minskade förluster
The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.
Mänsklig säkerhet i Sudan- För vem och mot vad?
The concept of security is a contested one. The United Nations definition in UNDPs Development report of 1994 is the most authoritive and commonly cited. The civil war in Sudan has led to 2 million deaths and over 5.5 million refugees. In a resolution from 2005, the UN decided that the war in Sudan was a threat to international security and peace. The 10th of January UN decided that a peace commission ought to be send with 10 000 military and civil men including 700 policemen.The main purpose of this thesis is to improve our knowledge of those factors which can cause an increased risk of conflict within a state, and how that can affect the social conditions for individuals.
Föreställningen om Australiens outback : En diskursanalys av australiensiska officiella webbsidor
The Internet is a constant source of information about the world and has contributed to the globalization of texts and pictures. A part in the tourists process of consumption involves looking at pictures and read about places that create an image of places that they have never been to. Websites are therefore important as a first impression and it is here that places are being represented. Places are created on the Internet and the Australian outback is an example of this. The study is interesting because it can be used to understand the relationship between people and places.
Framtidens kongresshus : Stadsbyggnadsvisionen i Jönköping
Since a couple of decades the community of Jönköping has worked out an urban vision of how the city should be appropriated expanded. The prospect extends to around year 2040 and deals with the area south of lake Munksjön in Jönköping, Sweden. Today there is a proposal of how this would look like and what main public functions that should be located there. One issue in the so-called urban vision 2.0 indicates a congressional building. This report describes how such an object can be designed according to the urban vision conditions.The work is focused on three main themes;* Architectural concept and a modern form of expression.* A functional attractive congress building in a new planned town centre.* General concept of a realistic structure system that meet the spatial and architectural possibilities.Various concepts in the meeting industry and in the architecture field are identified in order to understand the concepts and ideas with today´s congress buildings.

Schartau och efterföljare - Personen och traditionen
Henric Schartau was the prominent figure in a Christian revivalist movement thatspread mainly in south west Sweden during the 19th century. Priesthood followers in thetradition, commonly named Schartauans, often preached from his drafts, and were generallyvery loyal to the state church. Schartau and his followers placed a strong emphasis onministry and correct biblical teaching. The movement had a great impact on the diocese ofGothenburg for a protracted time period..
Export of wood pellets from British Columbia : a study about the production environment and international competitiveness of wood pellets from British Columbia
The global wood pellet market has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 million tonnes by 2020. These forescasts raise the questions which regions that can supply this vast amount of wood pellets and what the conditions are for producing it.
This study evaluates the conditions for wood pellet production and export from British Columbia, on Canada?s west coast, focusing on existing industry structure, raw material supply and the distribution chain.
A screening for Schmallenberg Virus among sheep and goats in Tanzania
Schmallenberg virus (SBV) is a novel arthropod-borne orthobunyavirus emerging in Europe in 2011 to 2012. Acute SBV infection causes diarrhoea, fever and reduced milk production in dairy cattle, but it is mainly the reproductive disorders (abortions, malformed foetuses and stillborn animals) in ruminants that have caused substantial economical losses. The prevalence of the virus outside of Europe is poorly investigated. SBV or SBV-like antibodies were detected in Mozambique in 2013, which raised interest for a similar study in Tanzania.
In this study in Tanzania, blood samples were collected from 478 sheep and goats from 39 herds in 15 different villages in three districts, covering areas in the north, south and east of Tanzania. The epidemiology of the virus was investigated by tracing antibodies by ELISA and mapping of the virus by PCR was started.
Stormskador i stickvägsgallrade bestånd i sydvästra Sverige :
A storm in January 2005 felled 75 millions cubic metres of forest in South Sweden. Previous studies of wind damage in thinned stands indicated the importance of early thinnings. The risks of wind throw increased by increasing age and height of the stands. Previous studies also indicated increasing risk of wind throw along the strip roads. The aim of the present study was to investigate wind damage in Norway spruce stands in South Sweden in relation to time of the first thinning and different pattern of strip roads (width, length and direction).
Friluftsliv på gymnasiet : En jämförelse mellan friluftslivsinslag i tre svenska gymnasieskolor
AimThe purpose with our study has been to investigate if upper secondary high schools in the south of Sweden, Stockholm and north of Sweden follow the outdoor education regulations stated in the curriculum (Lpf-94). Moreover, we aim to study if the teachers? previous experiences as well as the students affect the outdoor education. Finally, the purpose is to find out how the outdoor-life-education can be improved. These are the research questions:o How do the chosen high schools follow the outdoor education regulations stated in Lpf-94?o What obstacles, advantages and differences exist between the outdoor-life-education in these high schools?o In what way do the teachers? outdoor life experiences influence their education at school?o How can the students influence the outdoor education in their High Schools?o How can outdoor education be improved?MethodThe study is based upon data collected from four interviews with PE ( physical education) teachers from four different high schools.
Short-term responses of the field layer vegetation in a south Swedish deciduous forest after establishment of wild boars (Sus scrofa)
Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to
impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in
deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate
deciduous forest.

Habitat use and ranging behaviour of GPS tracked juvenile golden eagles (Aquila chrysaetos)
Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until migration.
The juveniles fledged at the end of July and beginning of August and initiated migration during October and beginning of November. The length of the post-fledging period, until migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.
