Analys och gestaltning av miljön kring vattentornet i Uppsalas stadsskog
The water tower in Uppsala city forest was built in the late 1950's in what is now a nature reserve. The unique place was supposed to be visited by people, which is currently not the situation. This bachelor thesis aimed to perform an analysis and make a design proposal for the environment surrounding the water tower. The analysis was performed using the methodology previously described by architect Arne Branzell. The methodology focuses on how a space is perceived by a person moving through it.
The vertical farm : varför har idén uppkommit och hur är den tänkt att fungera?
By immersion in the situation of the food production today and a historical study of how past development has led us to this point, one goal of this essay is to discuss whether the current way of farming can be applied in a sustainable future. Another objective of the essay is to study the vision Vertical farming as an alternative approach, and to focus on different aspects of this phenomenon in order to provide as comprehensive a picture as possible.The paper, thus, seeks to broaden the views for alternative approaches regarding a well-established method which we often take for granted. The aim is also to initiate a discussion around the need to also take radical ideas in regard if we want to face the future in a sustainable manner. The method is a qualitative literary study where scientific articles and papers have been used to discuss the issues: why has the idea of Vertical farming arisen, what is Vertical farming and how is the Vertical Farm meant to operate? Does Vertical farming have a place in the sustainable city of the future? For a long time us humans lived as one with nature, in a symbiotic relationship in which we gave and took as a functioning part of an ecosystem.
"Danmarks fremtid dit land - dit valg..." - En analys av Dansk Folkepartis bok
I min uppsats har jag valt att undersöka Dansk Folkepartis bok Danmarks fremtid dit land - dit valg. Jag har främst gjort en retorisk analys av materialet utifrån Lennart Hellspongs bok Metoder för brukstextanalys. I kombination med den retoriska analysen har jag även valt att använda Teun van Dijks bok Elite discourse and racism för att få en breddare förståelse av materialet. Med hjälp av van Dijks bok och hans diskussion av olika retoriska strategier och diskurser försöker jag göra det lättare att förstå och se Dansk Folkepartis sätt att påverka. Jag för även en kortare diskussion av bilder och dikter som förekommer i boken..
En värld av ?i? och ?u? : -En studie av u-länder i geografiböcker för gymnasiet
I uppsatsen har två geografiböcker för gymnasiet studerats. Fokus för undersökningen har varit böckernas framställning av "de andra", i det här fallet representerat av periferin, u-länder eller tredje världen, beroende på vilket uttryck som väljs att användas. De två undersökta böckerna, Geo- guiden och Geografi- människan, resurserna, miljön, brukar främst begreppen u-land och i-land för att beskriva världens fattiga respektive rika länder. Även begreppet NIC-land förekommer i böckerna men inte i samma utsträckning. Geografi- människan, resurserna, miljön presenterar även begreppen centrum- periferi, vilka dock inte används i särskilt hög grad.
Miljökonsekvensbeskrivning för en utökning av befintlig djurhållning :
In the last few years the environment becomes more watchful, even for us farmers.
All agricultural enterprises that exceed 200 animal units must be tested according to
regulation of environment. A farm business with 200 animal units and more is classed
?environmentally hazardous activities? and has to make an environmental impact
assessment for the business you have today, and the activity after expansion.
Before you can construct a building and expand the numbers of animals is a lot of
applications to make. I have in this project restricted me to establish a environmental
impact assessment and a consultation foundation.
To make a environmental impact assessment is the big part of the application. The
environmental impact assessment take a lot of time and you need skills for all the rules
in the environmental code to be abele to make an environmental impact assessment
approved.
The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws.
The purpose of the environment code is to promote sustainable development which will
assure a healthy and sound environment for present and future generations.
Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall
mean the discharges of wastewater, solid matter or gas from land, buildings or structures
onto land or into water areas or ground water.
Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations.
The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.
Viltanpassad röjning längs skogsbilvägar som en foderskapande åtgärd för älgen
The moose is a keystone species in the boreal forest ecosystem, but the dense Swedish population do cause some serious problems. From a forestry perspective, their browsing on young Scot pine (Pinus sylvestris) causes extensive losses of revenue. Adjusting the cleaning along roadsides of low trafficked forest roads can favour the production of plant species preferred by the moose. This is thought to redirect the moose´s browsing to the roadsides and thereby decrease the damages on commercial forest.The aim of this study has been to present a first evaluation of the vegetation in roadsides, one year after wildlife-adapted roadside clearing has been undertaken. In the wildlifeadapted clearing operation, the roadside was widened by removal of some trees in the forest edge whereupon a complementary clearing with a conventional chain flail was conducted.
Fortsatt gran eller självföryngrad björk efter stormfällning? : en ekonomisk analys
The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district.
The aim of this master thesis was to present an economic analysis of Norway spruce versus
birch.
Utvärdering av en subjektiv metod för att skatta mängden trädbiomassa längs vägkanter :
Forest biomass is becoming an increasingly important source of renewable energy, and thereby the demand is increasing. There is currently 213 000 km of forest roads in Sweden that could be suitable for biomass harvesting. Harvest of biomass along forest roads both provides biomass and maintains the quality of the roads. Currently, the volume of biomass along roads can only be assessed post harvest, chipping and industry deliverance.
As the decision of whether or not to harvest should preferably be based on more than experience, the TJ-method has been proposed. The TJ-method is a subjective method to quickly determine the dry matter quantity with the assessment being conducted from the roadside.
Rumslig fördelning av grov gammal tall i Uppsala stad med tallticka som indikator på höga naturvärden :
Fragmentation and reduction of forest area is a threat for many forest species and their habitat. Deficiencies in forest quality, such as lack of dead wood and old trees, are one explanation of the threat. The most important action to prevent the continued loss of forest types is to protect forest, but also to restore and to create areas that not previously had high nature values. Hence one of the key strategic roles for Fritid- och Naturkontoret, Uppsala municipality, is to monitor biodiversity in the context of urban planning.
The majority of the Uppsala municipality residents live in urban areas and most of them spend some of their spare time in natural areas in cities and their immediate surroundings. Exploitation in and around Uppsala is high, but it is important that there is enough nature close to houses to meet the residents? needs of recreation.
Växelkursens betydelse för utrikeshandel : En jämförelse mellan ett EMU-land och Sverige
Uppsatsens syfte är att analysera den nominella växelkursens påverkan på utrikeshandel och göra en jämförande studie mellan ett EU-land (Sverige) och ett EMU-land (Tyskland). Fokus för denna undersökning kommer att ligga på vad som skedde med utrikeshandeln under de två ekonomiska kriserna på 2000-talet, men även ge en generell bild för utrikeshandeln under hela perioden 2000-2010. Uppsatsen avser att besvara om det finns några skillnader i hur ländernas handel påverkades under kriserna med avseende på växelkursen, samt om handelssammansättningen av handelspartners förändrats. Detta kommer undersökas för att se hur Sveriges utrikeshandel påverkats av att stå utanför EMU.Resultaten visar på att den nominella växelkursen inte haft stor betydelse för utrikeshandeln under den undersökta tidsperioden. Både export och import har ökat under perioden, men det går inte att finna någon direkt koppling till växelkursförändringar.
Miljonprogrammet : mytbildning, arkitektur och förnyelse
Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. Since stump harvest for biofuel may increase, the amount of dead wood will decrease even more, which may threaten biodiversity. The first aim of this study was to compare the amounts of fine woody debris (FWD, .

Jämförelse av de nationella normerna i Eurokod inom Norden
Masonite Beams AB är ett företag som är väl etablerat i Sverige men har för avsikt att expandera till främst Norge, men även till de andra Nordiska länderna. Masonite Beams behöver därför skapa nya spännviddstabeller för sina I-balkar med hänsyn till de olika nationella bestämmelserna i respektive land. Detta examensarbete behandlar de olika nationella kraven för Sverige, Norge, Danmark och Finland för bostadsbjälklag. Arbetet omfattar en dimensionering i respektive land för ett HI300 bjälklag. Samtliga aktuella länder baserar sin dimensionering på Eurokod med nationella bilagor.De olika nationella valen till Eurokod resulterade i stora skillnader i den maximala spännvidden för ett HI300 bjälklag.
Markskador vid GROT-uttag : en enkätstudie hos skogstjänstemän
Forestry is increasing on an industrial scale where collection of logging residues takes a greater part. This has resulted in more machinery and heavy machinery driving in the clear felled area, this increases the risk of soil damage that will occur in the form of soil compacting and rutting in the clearings. This affecting on the nature in a negative way and especially in rivers and lakes that are affected by siltation and acidification leading to increased levels of heavy metals and methyl mercury. The purpose of this study was to investigate why there is damage to the ground when working with the slash in forest management from the forest officer point of view. A self-designed questionnaire was used and 45 questionnaires were sent out to various companies all over Sweden.
