Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?
Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. As a consequence of this, and a more diversified view on which goods and services forests should deliver, there is an increasing interest in broadening the range of silvicultural methods that are used.
The term continuous cover forestry (CCF) represents a suite of methods that have gained increasing interest in the Nordic countries. In CCF a considerable amount of the trees are left after harvest to favour values that require a continuity of tree-covered areas. There are thus hopes that this method will meet the needs for maintaining biodiversity and satisfy social and cultural values.
Nätverkets och användarens påverkan på latens i en Virtual Desktop-miljö
I en värld där kraven på flexibilitet, säkerhet och hårdvaruoptimering är nyckelfaktorer när det kommer till att välja IT-miljöer för företag blir virtuella skrivbord mer och mer poulära. Med dessa miljöer finns det också problem när det kommer till användarupplevelsen om nätverket ifråga inte kan uppfylla de krav som ett sådant system ställer. I detta arbete undersöks implikationerna vissa nätverksvariabler kan ha för en Virtual Desktop-infrastruktur, VDI. För att belysa dessa problem har två tester utförts på en VDI miljö. Det första testet gick ut på att mäta latensen då skrivbordsmiljön renderades för klienten från virtualiseringsservern vid olika nätverksdiamterar.
Att systematiskt hantera kunskap vid planering av ny infrastruktur : En fallstudie om skyfallsskador på riksväg 90 i Kramfors kommun
Natural disasters are becoming more common due to climate change and it is important to adapt the society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to increase in the future. The extreme rainfall that occurred in Kramfors municipality in September 2013 led to flooding and destroyed several roads, including highway 90, which recently both had been rebuilt and given a new stretch of road. Extreme rainfall had also occurred in the municipality earlier. The aim of the thesis was to examine how the Swedish Transport Administration handles new knowledge gained after natural disasters and how this is used in the planning of new roads.
Miljömedvetenhet, miljöansvar och miljöbeteende En kvantitativ analys av det ekologiska medborgarskapets grunder
I samhällsdebatten om hur det hållbara samhället ska uppnås framhålls idag allt oftare individens bidrag till miljöproblemen samt dennes ansvar för sina handlingar och dess konsekvenser. Hur individbeteenden bäst förändras råder det dock delvis delade meningar om, och i den debatten står Ecological Citizenship-teorin för en syn på långvariga beteendeförändringar som styrda av vår inre motivation. Man antar ett samband mellan individens medvetenhet om miljökonsekvenserna av sina handlingar och dess beteende, och att detta samband förmedlas via en positiv attityd till individens personliga miljöansvar. Det är dessa samband som studeras i denna uppsats, med hjälp av statistisk analysmetod undersöks miljömedvetenhetens direkta och indirekta effekter dels på aggregerat miljöbeteende, och dels på tre olika typer av miljöbeteenden, nämligen resurssparande beteenden, transportbeteenden samt konsumentbeteenden.Resultaten av studien visar på att en indirekt effekt av miljömedvetenhet på aggregerat miljöbeteende via attityd till ansvar mycket riktigt föreligger, en dryg tredjedel av den totala effekten av miljömedvetenhet går vägen via ansvar. För de tre undergrupperna av miljöbeteenden framträder resurssparande beteenden som mest påverkade av både miljömedvetenhet och attityd till ansvar, men det är för transportbeteenden som den indirekta effekten utgör störst andel av den totala effekten.
Utveckling Ulricehamn- om stora förändringar i en liten stad :
The purpose of this thesis is to inquire how a small town can be affected by some planned changes in the physical structure of the town, and how its inhabitants can benefit from those major changes. The town in question is Ulricehamn, and of the four projects considered, two concerns infrastructure. A new railway and a new locality for the major road, today passing through Ulricehamn. The other two projects are run by the local authorities, that is the planning of a modern town park by the lake, and a new public building for cultural purposes. There are no guarantees that any of the four projects will ever be realized, but in the process with this work, they have been considered as already a fact.

Trakthyggesfria skogsbrukssätt : kunskap, förutsättningar och attityder
Forestry has three main aspects to take into consideration today; economical, ecological and socio-cultural. In order to reach the broad policy goals for sustainable forest management, an increased variety of management approaches are requested. Today clear-cutting is the only method used in 96 % of the managed forests in Sweden. The Swedish National Board of Forestry has therefore initiated a project in order to investigate and develop Continuous Cover Forestry (CFF). This study is a part of this project.
Samband mellan virulensgener och VTEC-infektioner : Riskklassificeringssystem för VTEC
To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.
Korsförlamning : etiologier, diagnostik och terapi.
This report is a literature review that aims to describe marketing contexts for mango production in Kenya. The institutional conditions in the country are not well developed for marketing purposes, which causes many difficulties and problems for the society. In Kenya most mango producers are poor small-scale farmers with limited resources. Mango is a perishable commodity and to keep its value and quality it is essential to have the opportunity to sell the mangos in the right time. Inefficient and undeveloped infrastructure and marketing systems hinders the mangos to reach the market in time though, which causes large losses of produce.The Kenyan mango production has increased during the last decade but due to market losses for the producer, the small-scale farmers? profits have not improved.

Social hållberhet genom medborgardialoger : exemplet Husby
Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.
