Green structure planning in Transit-oriented Development (TOD) : a spatial analysis of Önnestad
During the winter 2011 Isaksson and Andersson did a time budget study on Nordens Ark?s Przewalskis horses during daytime when there were visitors and caretakers in the park. This time budget study was made during daytime and when there were no visitors or caretakers in the park. The horses where observed in the morning (5.30-6.30 am) and in the evening (5.45-6.45 pm) during four days. In addition to a time budget, the horses? positions in the enclosure were registered.
Klimat & Patriarkat : Genusgeografi i Huddinge
The essay deals with gender aspects on climate change adaption. The aspects consist of the fact that women in Sweden drive cars less than men, and that women in the developing world are more affected by natural disasters arising from global warming. This study was carried out in the municipality of Huddinge, a suburb to Stockholm, by interviewing one Agenda 21 coordinator, one planner and one student in genderstudies. I also attended a meeting in the Committee for built environment in the Huddinge Municipality, to ask the politicians questions and observe gender structures during the meeting. The results also consist of a search for gender-related words in the documents used in the essay.The results are analysed using ecofeminsim, a theory that connects woman subordination and environmental destruction.
Förskolekulturens möte med det mångkulturella samhället : ett möte mellan pedagogen och föräldrarna
My main question in this essay has been: why does the preschool advocate being outdoors? How should we respond to parents who have a different view on this? Children's right to participation and influence is also a question that I raise. How should we preschool teachers do when we stand between the child's desire to be out and the parents wish that their child should be indoors? By reading what is written in the preschool curriculum on children's influence, I have come to the conclusion that we preschool teachers must listen to what the children express that they wish to do, otherwise we go against our policy documents.My dilemma is about how to respond to parents who have a different opinion on being outdoors than we have. Many parents express an aversionagainst their children having to be outdoors.
Lantbruket som energiproducent : tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
A third party access to district heating networks has been proposed in Sweden, to increase the competition
on the district heating market. Such third party access could create opportunities for the agricultural sector
as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel.
The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant.
In the study, an estimation of the profitability has been made by estimating the cost of the investment,
personnel, operating and maintenance costs and costs for the fuel and ash handling.
Markberedningsresultat och plantbildning med såddaggregaten Humax 2-4 och KSM-såddskopa
Fördelarna med skogssådd är bland annat att de kan ge stamtäta bestånd med potential att producera träd med bra vedegenskaper och bättre utvecklade rotsystem samt att sådder har en högre biomassaproduktion per ytenhet jämfört med planteringar. Nackdelar som kan nämnas är att de ofta täta förbanden ger ökade kostnader vid eventuella röjningar och att föryngringsresultatet är mera osäkert för sådd än för plantering.Mekaniseringen av skogssådden startade under 1970-talet. Humax och KSM är två kranspetsmonterade aggregat för skogssådd. De har utvecklats för att användas på marker med svår ytstruktur där dragna såddaggregat som harv och högläggare har svårigheter att skapa tillräckligt mycket lämplig såddbädd på grund av att aggregatet inte kommer ner mellan hindren eller att basmaskinen inte klarat av att köra över hela arealen. Fördelen med KSM och Humax är att aggregaten är kranspetsmonterade vilket gör att föraren väljer var aggregatet skall markbereda och på det viset kan markberedningen göras mellan hindren samt att kranarmens räckvidd gör att basmaskinen inte behöver köra över hela arealen som skall markberedas.
Naturhänsynen i FSC-standarden : vetenskap eller gissningar?
The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.
Betets avkastning på olika typer av naturbetesmark : en fält- och metodstudie
AbstractA prerequisite to be able to use semi-natural pastures in an optimal way is knowledge about their conditions and properties. One thing to consider is the amount of herbage mass that can be produced during one season on different types of semi-natural pastures. That knowledge makes it easier to choose which type of animals and how many you are able to have in each paddock to maintain a high biodiversity and achieve the desired production of the animals at the same time.This study was performed in nine different semi-natural pastures around Uppsala. The paddocks were already mapped with regard to different vegetation types. Exclosure cages were placed on previously fertilized, mesic, dry, shaded and wet vegetation.
Provrumsbelysning
The fitting room is an important part of a clothing store, it's often where the customer decides if they want to buy the garment or not. Therefore it is important that the customer can feel safe and comfortable when they are trying the clothing. A typical fitting room in Sweden today has only one bright spotlight that emits light either towards the face or from the ceiling above. This study explores possible lighting solutions that take into account the customer's experience in the fitting room.The study aim to increase understanding of the importance of a good light in fitting rooms, so that customers gets a nice experience and that clothes, body shape and facial features are shown in a natural way. The issue therefore included how lighting can affect the customer's perception of the clothing and how the perception of body shape, facial features and the clothes change in different lighting solutions.To answer these questions, observations were made in various clothing stores, followed by an experimental study divided into two parts.
Skördemetoder av industrihampa :
Hemp is an old agricultural plant and has been used for hundreds of years for making
textiles, ropes and other fibre products. In the middle of the last century the Swedish
government prohibited all growing of hemp. Natural fibres were replaced by syntetic
fibres instead. Today there is a newly awakened interest for using natural fibres from
renewable materials. Growing of industrial hemp for fiber is allowed in Sweden
again.
I want in my Paper give Swedish growers an insight of which harvesting methods that
have been tried in Sweden and how they worked.
Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana
In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself
better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure.
The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.
Att uppfylla miljökvalitetsmålen, ett omöjligt mål? : Styrmedel och hinder på vägen för att nå målen Begränsad klimatpåverkan, Bara naturlig försurning, och Skyddande ozonskikt
Purpose: The purpose is to examine more closely why the achievement of the environmental goals is so low. To within the thesis work to make this as interesting and with as good quality as possible, especially the environmental quality goal Reduced climate impact, but also Natural acidification and Protective ozone layer, has been chosen to be studied further. Method: A qualitative method and text analysis has been applied. Intervention theory, as Vedung 2009 describes, is used as an intellectual backbone and as a help to structure the essay. The three environmental quality goals correspond cases, or units of analysis. Analysis: The fulfillment of the respective environmental quality goals is analyzed according to its goal, policy instruments, implementation and its effects. To this some of the problems are analyzed that exist on the path to achieve the goals.
Föreställningar om barn inom I Ur och Skur - en idé- och ideologi analys
Sweden is currently a country in which a large amount of children?s time has changed to be spent within institutions, for small children these institutions are preschools. These are places where notions are created regarding what children are, what?s good for children, what?s normal and desirable regarding children. The purpose of this study has been to decipher what?s considered desirable and what notions or ideas regarding children are prevalent in preschools with an I Ur och Skur profile.
Inhysningssystem för växande ungtjurar
The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.
Synen på "den andre" i ett segregerat område i Kalmar : en studie gjord ur två utlandsfödda mäns perspektiv
Edward Said's book Orientalism (1978) is the most important reference point in the post-colonial theory and describes how the West is dominant over the Orient. There is a clear distinction between "us" and "the other" and the purpose of this study is that, from a postcolonial perspective, focusing on Said's theoretical concepts "the other" and "discourse", examining how two foreign-born people with ethnic backgrounds living in the same place, are looking at themselves, at other foreign-born and native Swedes. My questions to answer this are; ?what are the concepts of "the other" and "discourse" and is it possible to use these concepts to examine how foreign-born people are looking at themselves, at other foreign-born and native Swedes in a specific location??, ?who is "the other" in a place where there are almost as many native Swedes as foreign-born??, and ?how do these two foreign-born people with ethnic backgrounds perceive Norrliden as a place and what effect has that place had on their identity?? I have used a post-colonial philosophical ground and a qualitative approach, focusing on two different interviews with two men, living in Norrliden. In Norrliden almost 50% of the inhabitants are foreign-born were both of the interview-persons are feeling safe and secure.
Ekologiska livsmedel i offentlig måltidsverksamhet
In our everyday life we are faced with many choices that have consequences on the environment. One of these is the food we choose to eat since food production has a big impact on the environment. In organic production the aim is to have a natural production process, where environmental impacts are minimized. By choosing organic food it is therefore possible to contribute to a better environment. A large number of meals are served every day in the public sector, which makes it an important player in the consumer sector that could make a major difference for the environment..
