Managing urban development : A case study of urban forest?s sense ofplace in Hammarbyskogen, Stockholm

Due to the growing population in Stockholm, some of the urban green areas are beingsubjected to exploitation. Hammarbyskogen is an urban forest in the south of Stockholm andis an example of a green area that is planned to be transformed into an urban environment.This paper investigates key qualities and values of an urban forest of Hammarbyskogenvalued by local inhabitants of the neighbourhoods of Hammarbyhöjden and Björkhagen in thesouth of Stockholm. In addition to that, the study seeks to investigate people?s perception ofthe planned development of the forest as well as investigate how these perceptions andqualities are being incorporated into the process of neighbourhood development.Using text analysis, interviews and discussion forums, findings have been made showing thatthe local inhabitants value the urban forest mostly for its ecological and recreational qualities.Regarding perception of the change, people are either positive or negative to the developmentwhich can be explained by people?s experienced sense of place and place attachment of thearea and the forest itself. The study has also shown that the urban planners rely on localinhabitants? view, as well as on expert knowledge during the process of planning.The results of the study contributes to a better understanding of why and for what purposesurban forests are important for the city dwellers..

Undersökning om möjligheten till småskalig vattenkraft i Björkefalls kvarn

I dagsläget när intresset för miljövänlig energi ökar, ses den småskaliga vattenkraften som ett sätt att minska Sveriges import av energi. I Sverige finns det tusentals nedlagda kvarnar och små vattenkraftstationer som med små medel skulle kunna börja leverera energi. I Björkefall i Olofströms kommun finns en privatägd och övergiven kvarn. Detta arbete undersöker möjligheterna till en småskalig vattenkraftstation i denna åt Olofströms Kraft AB.Småskalig, vattenkraft, elkraft, generator, turbin .

Majstorkning :

The corn plant came to Europe with Christopher Columbus in the 14th century and have ever since bin cropped here, but corn haven?t bin very common in Scandinavia until recently. The mainly use for this crop silage but even corn for grain is cropped in Europe. Corn for grain is a common part of feed in beef and chicken farming. In Sweden corn for grain is pretty rare but almost 1000 hectares are used for this crop, Lantmännen Sverige is the biggest buyer of corn at the moment.

Årstidsdynamik för kvicksilver i ett sövattensediment :

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

Design Program for Dessie Campus, Wollo University, Ethiopia

A geographical position and its social, cultural and political context as well as climate and specific physical characteristics define the scope for a landscape design project. This has become clearer for us in our master project where we have made a Design Program for the outdoor environment of Wollo University in Dessie, Ethiopia and analysed and reflected on the work and process. The aim for the project has been to design an attractive and functional outdoor environment for the Campus, based on the inventories and the needs and wishes of clients and users. But, the aim has also been for us as landscape architect students to gain a greater knowledge about landscape architecture and the design process by position ourselves outside our usual context. The method has been open and seeking where the site, literature studies, dialogues with people and our own experiences from the field study in Ethiopia has influenced the work. Wollo University is situated 400 kilometers north of Addis Ababa, in a mountainous landscape. It faces problems of heavy rainfall during the summer, soil erosion, a lack of essential facilities, and is still a construction site with empty spaces in-between buildings and infrastructure.

Psykisk ohälsa bland barn och ungdomar i socialtjänstens öppenvård. : En kvantitativ studie om psykisk ohälsa, kön och socioekonomi i Södermalm och Rinkeby-Kista utförd med ?the Strengths and Difficulties Questionnaire?(SDQ)

The aim of this quantitative study is to describe the prevalence of mental health problems within the group of children and adolescents who receive support from two in home care units within the social services of Rinkeby-Kista and Södermalm stadsdelsförvaltning in Stockholm. Another purpose is to examine whether socioeconomic background and/or gender are associated with the prevalence of poor mental health, or mental health problems of a specific kind, in the studied population. Mental health is measured with the SDQ, a behavioral screening questionnaire that is widely used in Sweden and internationally. The study is based on data collected by the two units, which routinely screen children and adolescents with the SDQ. The main results of this study indicate that mental health problems are common in the studied population.

Ekologisk konsumtion : Vanas och kunskapens makt

Miljöproblemen blir allt mer aktuella, människor blir mer upplysta och utbudet av de ekologiska livsmedlen ökar i butikerna. Allt fler börjar handla ekologiskt, men fortfarande är det merparten som väljer att inte handla ekologiskt trots att de har en positiv inställning till ekologisk konsumtion. För att klargöra vad som ligger bakom konsumentens val av varor intervjuades fyra informanter, två som till vardags handlar ekologiskt och två som handlar konventionellt.  Det finns många anledningar till varför inte konsumenter väljer att handla ekologiskt. När konsumenten står för ett val av vara så är det flera kriterier som spelar in så som kvalitet, hälsa, pris och etiska aspekter. Förutom dessa kriterier så handlar konsumenten utefter vana, kunskap och grupptillhörighet.

Comparison of three IVC systems for mice, with focus on growth and nest building in juvenile mice

Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.

Urban odling : möjligheter för framtiden

By exploring different forms of urban cultivation and looking into future gains of sustainability, I want to focus on unconventional and perhaps necessary ways of building, living and making a living. This will be made through study of literature on the topic.Urban cultivation could be anything from a pot of basil in the kitchen window to a city farm. The core of the concept is that the food is produced where it is eaten, in or in direct vicinity to the city and that it is produced ecologically. There will be many benefits, ecological, economical and social.The world is at a turning point right now where consumption patterns and the industry processed food are questioned and it is important that the things we consume are genuineand authentic. We want food that is locally and ecologically produced; food that we can trust.

KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Smart seed : fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling

Oilseed rape constitutes a good break crop within a cereal dominated cropping system. The normal sowing time for winter rape in Sweden is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time.

Möjliga alternativ för att ersätta direktverkande el i flerbostadshus

I have in my thesis, examined the possibilities in terms of energy for a condominium association.To have an effective and good energy is becoming increasingly important with today's rising electric and oil prices. In my thesis I have used the condominium association Kärralyckan, which is situated in Falkenberg. The buildings at Kärralyckan are built in the mid-1970s, and are heated by electric radiators. The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.

Implementering och kommunikation av ekologisk h?llbarhet. En fallstudie om utmaningar och strategier i fordonsindustrin

The purpose of the study is to explore the internal implementation and communication of ecological sustainability within an organization and to identify obstacles and challenges that may arise. To address the study's purpose and research questions, a qualitative methodology and semi-structured interviews were used. Respondents were selected from two different units within a large global organization operating in the automotive industry. The study's findings indicate that the organization's sustainability efforts are extensive and integrated across several departments. It is also evident that sustainability initiatives are primarily driven by upper management within the organization, although there is room for lower hierarchical levels to provide some feedback.

Ekologiska perenner - Lokalt och globalt : En Intervju- och Litteraturstudie

AbstractThe customer demand for ecological products has increased in recent years, within the garden industry this mainly concerns herbs and other edible plants. The organic trend is increasing and more people are aware of the environment and want to take responsibility for it through their purchases for their garden as well.In this essay the aim is to investigate customer demand and the possibility of selling organicperennial plants in eight garden centres on the Åland islands and in Gävle/Sandviken. I include two garden centres with an organic profile to get a wider point of view. I investigate the global market for organic perennials and look further into existing certification standards on the Swedish market today.The methods I have been using are interviews and a literature study.The study shows that the experienced demand for organic perennials is small in both of myinvestigated groups. The biggest motivation for starting to sell organic perennials would be to find a supplier of these plants and that more customer would ask for them.
