Australia is one of the largest producers and consumers of fossil fuels in the world. In a society where the effects of fossil fuels on global warming are constantly discussed, the nation?s production and consumption are subject to debate. Problems arise when negative aspects of consumption, such as emissions of greenhouse gases, are put in relation to an increased need of energy and economic growth. However, it is important to distinguish between different types of fossil fuels when it comes to their individual impact on the environment and to analyze the possibilities to increase the more environmental friendly ones.

I examensarbetet ?Landskapsurbanism i en Post-Industriell kontext? diskuteras den relativt nya diskursen kring ?Landscape Urbanism? eller ?landskapsurbanism?. Arbetet fokuserar på platser som har övergivits av industrin, i skenet av den post-industriella utvecklingen. Huvudmålet med studierna av ämnet är att belysa ett antal ?landskapsurbanistiska metoder? och sedan tillämpa dessa på min plats: den gamla Cementafabriken på Övägen i Limhamn, Malmö.Den största inspirationskällan i detta är den amerikanske landskapsarkitekten James Corner´s teorier, och de metoder som utövas av hans landskapsarkitekturbyrå; ?Field Operations? i New York.Eftersom ämnet täcker in väldigt många aspekter och problemställningar rörande samtida urban planering och design, har jag i enlighet med Corner delat in min text under fyra rubriker:- Processes over time- The Staging of surfaces- The Operational or Working method- The ImaginaryDet gamla cementfabriksområdet har förvärvats av byggbolaget NCC, och kommer inom en snar framtid att bebyggas med bostäder.

In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be advantageous for future rehabilitation efforts of degraded rainforest. The objective of this study was to investigate how mother trees in secondary forest and different site factors affect the abundance and spatial distribution of natural regeneration of non-pioneer tree species in a tropical rainforest in Sabah, Malaysia. The study took place in the INIKEA Forest Rehabilitation Project area, which suffered from wild fire in 1983 and has been selectively logged over both before and after the fire. Natural regeneration and site variables were inventoried in plots, while mother trees were inventoried in the whole survey area.

Since studies points out declining interest in science among students in Swedish schools, I have in this paper chosen to examine how some students at the Social Science Programme are experiencing the lessons in Natural Science and how to make lessons more interesting according to these students.The purpose of this study was to gain a greater understanding of how teachers would develop new perspectives and tools to make lessons in Natural Science more interesting. I also wanted to investigate whether an intercultural perspective could be a possible tool to increase students? interest and motivation.As a theoretical framework, I have assumed Vygotskij's sociocultural perspective, Habermas's theory of deliberative conversations and an intercultural perspective. Through a qualitative approach, I conducted interviews with students and teachers. The main results showed that students felt that natural Science lessons were too theoretical and undemocratic and that they wanted to have more student interactions, such as discussions and group works.

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

In this thesis I examine how the phenomenological philosophy of Edmund Husserl and Martin Heidegger differ with regard to the phenomenological reduction, and in particular why there is no reduction in Sein und Zeit. I examine in what way philosophy is seen as an overcoming of the naïvete of a ?natural? attitude and how this natural attitude is understood, starting with Husserl?s descriptions of the phenomenological reduction, of the natural attitude of our daily lives and of his notion of transcendental subjectivity. By presenting these main aspects, I try to elucidate why, in Husserl?s view, laying the foundation of all knowledge must take form of a phenomenological first philosophy.

The demand för Swedish pork meat is increasing every day. This leads to agricultural farming having to develop as an industry, with larger and more rationalised units to make the farming more effective and to raise the financial profit. The consequence of this is that it affects the animals when their surroundings become more industrial. The pig´s natural behaviour becomes restricted by the limitations of the facilities, which leads to them becoming understimulated. Helena Kummel, a teacher at Munkagård upper secondary school and also an educated animal inspector has developed a prototype that could possibly replace the pig´s natural rooting behaviour inside the barn. The porpuse of this report is to study "bökboxen" in the gilts´actual living enviroment, through qualitative- and quantitative analysis.

I den här uppsatsen har användningen och betydelsen av ett utvalt antal översättningsekvivalenter av ord och fasta uttryck som betecknar ansiktsuttryck på svenska och mandarin studerats. Uppgiften närmades genom semistrukturerade intervjuer med modersmålstalare av svenska och mandarin, samt genom en korpusbaserad kollokationsundersökning. Analysmetoden Natural Semantic Metalanguage har använts för att beskriva det inre sinnestillståndet hos personer när de handlar på de sätt som orden och uttrycken beskriver, samt vilka känslor och tankar som tillskrivs dessa personer av dem som bevittnar handlingarna. Vissa intressanta skillnader mellan översättningsekvivalenterna har observerats..

The aim of this essay is to create an understanding, of how teachers comprehend knowledge, grades and tests in a school context. It is important to get a grip of the different parts of the teacher?s reality. The test, the grades and knowledge are deeply connected as a part of a whole. The teachers view on knowledge can not be understood without asking about the practical parts of their work and understand how the different parts are dependent on each other.The main material consists of interviews with four teachers that work in a public mandatory school in the south suburbs of Stockholm.

The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming.  I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

In this study, we investigate various lighting applications in a virtual environment, where we compare between light based in naturalism (natural light) and pictorialism (artistic light). The purpose of this study is to gain further knowledge in lighting, which is increasingly important for game graphics. Theory are examined to gather information and recommendations on how to use various light settings that convey different emotions. We then use this information to illuminate the environment that we have built. The environment is presented in Unreal 4 for respondents who are allowed to move around freely in the environment.

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

Vid adhesiv cementering, så kallad bonding, rekommenderar fabrikanter att glaskeramers cementeringsyta etsas innan applicering av silan. Att värmebehandla silan med respektive utan etsning, har i tidigare studier visat en höjning av bindningsstyrkan mellan olika material. Den litiumdisilikatbaserade glaskeramen IPS e.max® Press har funnits på marknaden sedan 2005 och få studier har gjorts på ytbehandlingar och dess effekter på materialet och bindningen till olika material. Syftet: att undersöka om ytbehandling med värmebehandlat silan ger en högre bindningsstyrka till adhesivt cement hos en litiumdisilikatbaserad glaskeram, jämfört med kombinationen etsning och silanisering. Material och metod: 12 litiumdisilikatbaserade keramiska block pressades. Blocken delades parvis in i sex grupper och ytbehandlades med etsmedel och/eller silan med eventuell påföljande värmebehandling. Blocken cementerades samman varpå mikrostavar sektionerades fram, som sedan termocyklades. 10 provkroppar ur varje grupp valdes ut för ett microtensile bond strength test. Frakturytorna bedömdes i mikroskop.
