Effekt av karbonatisering med biogas på aska från trädbränslen
It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.
Mosaikens Rosengård
Har de modernistiska principerna med industriellt byggande, funktionsuppdelning
och trafikseparering skapat en monoton bebyggelsekaraktär, brist på
mötesplatser och brist på lokal kommers?
Mitt antagande är att detta är fallet och frågan blir då hur vi kan utveckla
möjligheterna för att skapa fler mötesplatser och en dynamisk lokal kommersiell
verksamhet? På vilket sätt går det att öka variationen av bebyggelse och
lägenheter? Är det önskvärt att överhuvudtaget ändra i en redan befintlig miljö
med strikt hierarkisk struktur?
Examensarbetet kan ses som en pusselbit i det kreativa och långsiktiga arbetet
med att skapa en vision för stadsdelen Rosengård i Malmö. Jag vill redan från
början slå fast att jag inte syftar till att skapa ett universellt verktyg för
att lösa brister i miljonprogrammets bostadsområden. Jag utgår från
projektområdets speciella förutsättningar och relationen till övriga Malmö.
Syftet blir att föreslå en framtida stadsutvecklingen som innebär skapandet av
nya strukturer och förtätning av bebyggelse för att göra Rosengård till en
funktionsintegrerad stadsdel istället för dagens funktionsuppdelade struktur..
Tingsryds Travbana
Our bachelor thesis is a visualisation made in 3D-graphics of how the horserace
track in Tingsryd perhaps will look like in the future, complete with a
miletrack, steeplechase, and other horserace courses. Today, the race track is
only in it?s building phase. The inner field-group in Tingsryd needed
presentation material to show their eventual sponsors, so they contacted us at
Media Technology, and we instantly decided to give their idea a try..
Kommunalt naturskydd som en del av markanvändningsplaneringen : en fallstudie av olika synsätt i samband med upphävande av naturreservat
In metropolitan areas where the exploitation pressure increases, also the importance to point out nature areas grows, both for the sake of outdoor life and for biodiversity conservation. Since nature conservancy and spatial planning constitute two different parts of the municipalities land use control, a case study has been carried out in two municipalities in the Stockholm region, Huddinge and Järfälla. Both these municipalities have protected about one third of their land and today there are plans to repeal parts of the reserves to enable exploitation. This thesis shows ? from the theoretical concept of sustainable development ? officials, politicians and non-governmental organizations perspectives on questions concerning land use together with the work with nature reserves and repeals.
Projektering av passersystem : En studie i användarstöd vid offertarbete för ARX passersystem
To have a tool that guides you when you work with a complex system can be helpful since the complexity of the work can be reduced. In this thesis I explore the possibilities to use a helper application whilst planning installations of access control systems. The purpose of the application is to provide support during the planning and at the same time make the user aware of the limitations that exist in the access control system ARX Access. By combining early user input and the theory of formativity, the result became an application written in Java..
Trädslagsinverkan på markvegetationens utveckling i odlingsförsök med tall och contorta :
In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.
Miljöbedömning av mark- och vattenresurser i kommunal översiktsplanering : en fallstudie av en del av planprocessen i Tierps kommun
This paper describes the integration of environmental assessment in Swedish municipality
comprehensive planning through a chosen case study. The implementation of a new EGdirective in Swedish law, concerning Assessment of the effects of certain plans and
programmes on the environment, should lead to some changes in the way Swedish
municipalities' deals with environmental issues in their comprehensive plans. This could later on lead to new preconditions for municipality comprehensive planning.
The purpose of this study was to investigate how the planning organisation in the municipality adapts to new regulations for impact assessment of comprehensive plans required by the Planning and Building act. Secondly the purpose was to partly participate in the early stages of the planning process and thereby indicate and identify possible environmental impacts regarding the aspects of land and water. This was done as a case study in a well defined part of the process.
CAMPUS BTH - ett gestaltningsförslag och en studie av begreppet campus
This text answers the questions how do we define what a campus is, how the
concept of the campus came to exist and how it is used today, and how the
Blekinge Institute of Technology (BTH) campus can be designed according to site
conditions and the conclusions drawn from case studies at Chalmers University
of Technology and Karlstad University. The purpose of the case studies is to
gain insight into their campuses advantages and disadvantages. This finally
results in an interpretation of how the Blekinge Institute of Technology campus
can be planned. A campus is the area of land on which a college or university
and its surrounding buildings resides on. Campus as a concept meant a field at
first, it later evolved at American universities due to their design of college
campuses.
Gatuprostitution, varför där? - Fysisk planering och social säkerhetspåverkan på lokaliseringen av gatuprostitution i Göteborg
?Street prostitution, why there?? is about how the physical planning and physical environment affect the localization of street prostitution in Gothenburg. The aim is to increase the understanding of how social security is linked to man's immediate environment and are influenced by the physical environment. Important concepts that are explained in the paper are social security, prostitution, and physical planning.This study deals with theories about the factors that may influence why criminality localized to a specific area, such as legislation, urban planning and community. The study conducted interviews with the Gothenburg Police, Västra Götaland County Administrative Board, Gothenburg City, Stadsmissionen and Mikamottagningen.
Platskänslan på en innergård i Göteborg - En jämförelse mellan planerarnas vision och de boendes uppfattning
This case study, ?The sense of place in a courtyard in Gothenburg?, examines whether the city planners? vision correspond to the residents? perception regarding the sense of place and the physical environment in a courtyard in Gothenburg. By carrying out a questionnaire survey, the inhabitants? perception has been explicated, which we have then compared to the total vision for the design of the courtyard that we have gathered from doing interviews with the planning executive, the developer and the landscape architect as well as reviewing the development plan. The study has shown that the vision coincides relatively well with the residents? perception, but it differenciates when it comes to social aspects.
Tunnelseende - Vandringar genom Järnvägstunneln i Karlskrona
Ett öppnande
Det händer ibland att vi upptäcker platser som lyckas erövra en speciell plats
i våra medvetanden. Det är platser som sätter tankar och känslor i rörelse, och
som för en lång tid framåt väcker nyfikenhet och engagemang. För oss har det
ofta handlat om övergivna platser. Miljöer som formats av människans hand, men
som övergivits i takt med att samhället förändrats. I sin bortglömdhet väcker
de en svårbeskriven sympati, nästan som den till en gammal vän i behov av
kamratlig omtanke.
Viltets inverkan på vegetationsutvecklingen i en Sydsvensk skogsföryngring :
Herbivore impact on the Swedish forest has under a long time been a common subject of
debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).
Bostäder vid stränder och järnvägar - risker, attraktivitet och konflikter. Fallstudie: Öbacka strand i Umeå kommun.
This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.

Hänsyn till mark och vatten vid slutavverkning : en fältstudie på känsliga marker
The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines.
This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments.
The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done.
The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..
