Nya trädgårdsväxter för ett allt varmare Sverige

The aim with this work has been to examine the climate changes and what these has meant, and will mean during the present century, for plants that have not been hardy in Sweden. A lot of new species can probably be grown today in Sweden's most southern parts, due to an increase in the average annual temperature by 1?C. There is a need of information about these new species and their hardiness. The insufficient information about the subject has been the background to this work.

Inneklimatundersökning : Hur fungerar ventilationssystemen i två större lokaler och hur ser kommunikationen kring detta ut mellan hyresgäster, hyresvärd och projektör?

This examination paper is a study of the indoor climate in a theatre and a practice room for orchestras placed in Sickla in Stockholm. The designer of the ventilation system wondered if he had managed too make a good environment for the users and he also wondered which of the rooms that had the most desirable climate. The project includes polls for visitors, interviews of people connected to the rooms and measurements of the physical environment. The results show a small dissatisfaction about the thermal indoor climate, it?s a little bit to cold and the air draws.

Hälsoproblem hos strutsfåglar i Sverige : litteraturstudie och sammanställning av patologifynd

In the beginning of the 1990?s ratite breeding for meat production was introduced in many European countries, including Sweden. The knowledge of ostrich farming and diseases of ratites is increasing internationally but is still often limited among veterinarians. This report consists of a literature study and a summary of pathology findings from ratites submitted for necropsy to the National Veterinary Institute (SVA) in Uppsala, during 1995 to 2001. The purpose is to give a general introduction to ostrich and ratite breeding and to give an overview of the most common diseases. The necropsy data from 1995 to 2001, indicate that many of the diseases are management related rather than caused by infectious agents. Due to Cold climate ostrich breeders in Sweden need to supply well designed buildings and good care of the animal.

CFD simulering av kallras : Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla

Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available.

Inneklimatet på ett kontor : Undersökning av inneklimatet vån. G4 stadshuset samt kontor på Ånghammargatan

This report describes an investigation of the indoor climate in two different workspaces. Since we a big part of our lives are staying indoors in artificial environments, and more particularly in our workplaces, we think it would be interesting to do this investigation. The technical solutions for air treatment systems began with simple natural systems without fans and where the thermal rise of the air applied. In modern time is technical air treating systems used to take care of the fresh air supply. This type of units can supply filtered air with the right temperature to the building. Well-functioning ventilation is essential to bring clean fresh air to the room and effectively remove impurities without sound- or draught problems. The indoor climate is relevant for the output capacity.

Indianen och kalla kriget : Audiovisuella representationer av kalla kriget 1965-1986

The similarity between the Russian and the Indian, in a Cold War context, may be ambiguous considering the ethnic-social variables and the period in time from where the Indians relate. However, by analyzing these, as well as other, characters in the exhibition of movies, we could learn something about the ideology of the time from which the movies derive.This study examines ideology and movies in the Cold War era and concludes that the Indian, for example, may be representing the values of the common public enemy, originating from the Cold War ideology. The movies examined, regardless of influence of distinct Cold War themes or lack of such themes, carry attributes that give evidence of typical Cold War ideology. The fear of communism and common enemies connected to a Cold War context, the thought of America as the land of the free ? with the horizon in the ending of the movies as metaphoric to freedom ? and the moral rhetoric that connects to the American thought of a duty as a global savior, are all signs of the Cold War ideology.Even though the messages are somewhat clearer and more distinct in the movies with Cold War motifs, the fact that ideology is projected through other movies as well should be considered essential for the continuing study of movies as cultural artefacts..

ALTERNATIVA ASFALTSBELÄGGNINGAR : Möjligheten att använda icke petroleumbaserade bindemedel

This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a Cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.

Minskad trädtillväxt under Lilla sitiden? : En dendroklimatologisk jämförelse mellan nutid och 1600-talet invid trädgränsen i norra Skandinavien

During the period called Little Ice Age (1400 ~ 1900) the climate of northern Europe was in an annual year-basis overall colder than it was before and after that period. The numbers of short, cold and rainy summers and long, bitter-cold winters where often repetitive under the approximately 500-years the period lasted. In Scandinavia, the coldest time during this period is estimated to have started around the end of the 16th century and lasted to the beginning of the 18th century. Trees growing at the tree-line are limited by temperature for their annual growth and hence showing differences of growth during changes in the climate,  a method called dendroclimatology. The variations of growth can be read in the tree-rings either by analyze the width of the ring or by look into the density of the wood and is used to reconstruct past climates.

Historiografi och paradigm i forskningen om kalla kriget : En komparativ analys av diplomatihistoria och internationella relationer

Adopting a socio-cultural approach to the study of cold war historiography, this master?s degree essay is a comparative study of the two main disciplinary fields of cold war scholarship, diplomatic history and international relations theory (IR). The study applies the theory of scientific development formulated by Thomas Kuhn and the concept of paradigm on the field of cold war research.Diplomatic history and IR shows many similarities in their development, and in the importance different schools has had in scholarly debate. These different schools are analysed as paradigms, a concept that has been more willingly adopted within IR than in diplomatic history. The transition from what historian John Lewis Gaddis has termed Old Cold War History to New Cold War History is discussed in terms of paradigms and paradigm shift.

Klimatanpassning och lantbruket i Värmland : Klimatförändringarnas upplevda effekter på lantbruket och olika aktörers åsikter om klimatanpassning

Climate change is a global and slow process that affects humans all over the world. Climate adaption within agriculture is important to reduce the risks that agricultures are exposed to because of climate change.  Through climate adaption you can improve the positive effects and take advantage of them optimally. How the climate change affects agricultures varies depending on regions and societies. The purposes of the study are to examine how different actors experience the impacts of climate change on the agriculture in Värmland.

Klimatförändringar, ett problem för vem? : En institutionell policystudie om könets betydelse i svensk klimatpolitik 

The UN has a goal to gender-mainstream all politics, but its politics in climate change is not gender-sensitive. The Swedish government has the same goal concerning gender mainstreaming, but does the Swedish politics of climate change reach this goal? The aim of this paper is to examine the relations between the Swedish politics of gender and climate change. In addition, the aim is also to investigate how gender is constructed in the climate politics. To reach these aims, an institutional, policy and gender analysis is used.

Häckar för Norrland

I have observed that hedges are not as prevalent in gardens in the north of Sweden as in the south despite a number of beneficial qualities attached to their use. Consequently, the primary purpose of this essay is to examine the potential for the use of ligneous or woody plants as hedges in a Cold climate. The aim of this study is to provide information about the various varieties of ligneous plants that can be used for both pruned and unclipped hedges in the north of Sweden. Because the hardiness of the ligneous plants is a vital factor here, only plants that are hardy enough to survive in the Swedish hardiness zones V to VIII are included in this study. Roses, dwarf shrubs, conifers, bushes with a final height of less than 1 metre and plants that ?bleed? have been excluded.

Den försvinnande staten Tuvalu : En fallstudie om klimatflyktingars rättigheter och staters ansvar

This thesis aimed to, with the help of a case study, investigate and discuss state responsibility towards climate refugees. The state of Tuvalu was selected because of their vulnerability as a low-lying island state. This was fulfilled by on-site study how the state Tuvalu acted to climate threats, determine if the future migrants from Tuvalu can be counted as climate refugees and find out if they are by that definition included by the UN Refugee Convention. The result indicated that the state of Tuvalu is adapting to climate threats, that in the future the population can be seen as climate refugees, if they are forced from their homes due to climate change, and that they, despite that definition, can not be included by the UN Refugee Convention. The study also indicates a need for greater international protection of climate refugees by, for example, an expansion of the UN Refugee Convention so that these vulnerable people do not fall into oblivion due to a question of definition..

Valsningsteknik för extremt höghållfasta tunna stål

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

Dendroklimatologisk analys av lokalklimat vid Grövelsjön i Dalafjällen

Climate on earth is getting warmer, which effects earth?s energy balance and so forth the ocean and atmospheric circulation.  In many sub-polar regions on the northern hemisphere changes due to warming of the climate can be observed. Some examples that already have been observed are shifts in tree line, towards higher altitudes and latitudes, increased ablation of Swedish glaciers and melting of the permafrost on the Siberian tundra. In Sweden climate change scenarios tell us that it will become warmer and that a higher amount of precipitation in form of rain will be an effect from this. To study climate changes in Sweden, transition zones are useful in order to observe changes in distribution of species and animal populations.
