The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

AbstractIn this essay, I have chosen to examine how four teachers in a work unit think and work with linguistic development and strategies, particularly in grade 4-6. The teaching profession has gradually become more like a cooperative profession. Therefore it is in a general pedagogic interest, to know, how each one of the teachers in the work unit, are thinking about linguistic development, teaching profiles and the significances of a work unit to achieve their aims to provide for all the individuals in their classrooms. My intention was to find out if a homogeneous work unit or a heterogeneous work unit is to prefer in work with linguistic development, which initially made me focus and realise the importance of each one of my informants? answers.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

The first aim of this study is to describe how the public employment service (PES) producesoccupational descriptions. The second aim is to analyse the conditions for that production.Method: The empiric material consists of seven qualitative interviews with employed at PES,operational plan for the team working with descriptions on occupations and observation notes.The overall theme in the study is Foucaults perspective on power. The conditions forproduction of occupational descriptions are understood in the light of the governmentality perspectiveand the concept of employability. Bourdieu´s concept habitus, symbolic violence and capital are usedto articulate the officials? values and experiences.Eight officials at PES produce the occupational descriptions.

The productiontime in the construction industry contains of many different participants which will take part in different events. When there is so many people working with the same project it is easy tosee one self just as a part of the game. The consequence of this is that they don?t see themselves as important participants whos knowledge, opinions and experience can be useful in the whole production process. This might lead to that they feel neglected and the consequence of that will be lackof motivation.

Purpose: The study aims to analyze how companies can learn from past communications in critical situations and during corporate crisis, and see how they use this knowledge in the management of subsequent critical situations and corporate crisis. Furthermore, the media is analyzed to see how the newspaper industry chooses to reflect an organization and its actions, and also to see if the pressure through articles in the newspapers has an impact on the extent of the situation.Method: A qualitative case study of Sweden?s largest food company, ICA Sverige AB, where knowledgeable people in media management within the company are interviewed using semi-structured interviews, with support of quantitative methods by a collection of articles from the news press.Theories: Concepts, theories and models in crisis management and communication has been applied to relevant data. These comprise Knowledge Management, a communication template in crisis management, The Situational Crisis Communication Theory (SCCT) and the model Content of crisis communication.Empiric: Based on the quantitative data consisting of articles from four Swedish news sources: Svenska Dagbladet, Dagens Nyheter, Aftonbladet and Expressen, a semi-structured interview guide was created and carried out with the person within ICA who possesses knowledge of the subject area.Conclusion: ICA has during the priod studied exhibited to have used the concept of Knowledge Management in the development of their routines regarding product recalls at product defects. The relationships between ICA and the media have shown improvements, which has resulted in ICA percieve the media coverage as balanced, true and fair..

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.

Corporations meet complex challenges as they operate on a global market. Global multidimensional problems are referred to wicked problems and which cannot be solved only managed. In this case, of certified palm oil, palm oil production can be seen as a wicked problem due to deforestation of rainforest, land grabbing and social conflicts. There are also conflicts regarding the value and interest of palm oil. This thesis investigates the Swedish transformation for certified palm oil and how actors in the Swedish food market address this transformation to have certified palm oil in their production. The aim of this thesis is to explain enabling factors to address the governance gap of ethical sourcing in the food industry.

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

The importance of micropropagation has increased to provide the increasing fields with true to type and healthy plants. Traditional plants are growing on solid agar-based medium but lately liquid medium has become a new opportunity. This study has focused on a new bioreactor, developed on large scale micropropagation. Potato (Solanum tuberosum L. ?Semlo?), raspberry (Rubus idaeus L.

Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.

In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

Detta examensarbete har utförts vid Elitfönster AB i Vetlanda. Elitfönster AB är Sveriges största leverantör av fönster och fönsterdörrar.Syftet med arbetet är att ta fram åtgärdsförslag för att minska ledtiderna, då korta leveranstider blir ett allt viktigare konkurrensmedel. Arbetet innebar en kartläggning av nuvarande produktionsflöde och identifiering av problemområden.Arbetet genomfördes med hjälp av tidsstudier och intervjuer med arbetsledare och personal. Arbetet bygger även en hel del på observationer, iakttagelser och studerande av statistik.I stora drag kan man dra slutsatsen att de långa ledtiderna beror på främst två orsaker;? hyvelbanornas långa ställtider som medför körningar i veckosatser? kvalitetsbrister och bristfälliga kvalitetskontroller samt trästycken som ?försvinner? längs förädlingskedjan.
