Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050
The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The
goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties
of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP.
The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in
buildings..
Daglilja : en studie av växtslaget, handelskedjan och sortimentet
This thesis describes the genus Hemerocallis, the trading with daylily from hybridizer to seller with emphasis on the Swedish market. The first part describes the daylilies biology its botany, breeding, production, pests and diseases. Also the tobacco ringspot nepovirus recently confirmed in Sweden is described. Since the breeding of daylily is mainly done in Florida topics like hardiness and influence of the climate are included. The first part is mainly based on literature studies, but also interviews with growers and breeders from Sweden, USA, Holland and Germany.
Kan olika virussjukdomar blockera varandra? En studie baserad på övervakningsdata
Background: Infectious Diseases Institute points out that the potential of various viraldiseases possibly can block each other. It is said that the virus that causes common cold,Rhinovirus, may have saved many people from the flu. If this assumption proves true, itwould explain why some viral diseases in some countries have been slow to take off and pointto a new way to struggle influenza. Objective: The main purpose of this study, based onreported cases of RSV and influenza type A, type B and H1N1, investigate whether viraldiseases can block each other, i.e. difficult season of flu may delay and / or mitigate thespread of RSV in Sweden.
Små ingrepp med stora steg mot förändring : ett utvecklingsförslag i Durban, Sydafrika
Durban, South Africa?s third-largest city is a socially segregated post apartheid society, struggling with high unemployment and AIDS. The city becomes even more complex with a changing climate, creating an influx of people to the city, putting scarce resources under further stress. Warwick Junction, an important transport hub in the centre of Durban, holds a large site of informal trading alongside the formal markets. This informal sector generates large financial flows and provides for a rapidly growing population.
The aim of this thesis is to develop an approach that is realistic and relevant to planning and design of an urban context in South Africa.
Hållbara samtal. En studie om medarbetarsamtal och skolutveckling i gymnasieskolan i Sverige / A study on discussions about personal development and school development at upper secondary school in Sweden
Syftet med den här magisteruppsatsen är att få en bild av hur skolledare och lärare ser på kommunikationsformen medarbetarsamtalet, kopplat till skolutveckling, i den svenska gymnasieskolan. Uppsatsen följer en fenomenologisk forskningsansats, i vilken en etnografisk modell med åtta kvalitativa intervjuer av tre skolledare och fem lärare på två gymnasieskolor setts som en fallstudie. Materialet har analyserats med hjälp av en narrativ metod och kritisk diskursanalys (CDA) och resultatet visar att skolledare och lärare talar om skolutveckling på disparata sätt i medarbetarsamtalet men också att förberedelser och feedback på medarbetarsamtalet skiljer sig åt och upplevelsen av medarbetarsamtalet är därför att det inte påverkar skolutvecklingen på de två gymnasieskolorna..
N?r staten talar om kris och krig : En analys av broschyren ?Om krisen eller kriget kommer? 1943-2024
This study examines how the Swedish state has communicated security, threats,and citizen responsibility to the population through different versions of thebrochures ?If Crisis or War Comes?. Drawing on securitization theory and UlrichBeck?s theory of the risk society, the study analyzes how threat perceptions, protected referent objects, and the role attributed to individuals have changed overtime. The analysis is based on a deductive qualitative content analysis of sixbrochures published in 1943, 1952, 1961, 1989, 2018, and 2024.The findings demonstrate a clear transformation in the construction of threats,shifting from a predominant focus on conventional military conflict during theSecond World War and the Cold War to a more diversified threat landscape in thetwenty-first century, including societal disruptions, propaganda, cyber threats,environmental risks, and pandemics.
Dtourist: Historieskapande, interaktion och planering med rörlig media på webben
Bachelor thesis in Interaction Design by Håkan Carlsson, spring term 2007, Malmö
University, School of Arts & Communication.
The climate for video sharing online is somewhere in the border of becoming a place for only the big companies to distribute material with general interest, or small communities with genre-specific interest to attract a larger audience. In this article I will look at the travelindustry to see what possibilities can be implemented into communities with interest in planning and travelling. I will argue that the importance of collaboration with different media
can create a bigger picture so that more people can use and discover each other?s travel videos and experiences. I have also taken a closer look at social interaction at online communities such as MySpace and YouTube.
Konsekvenser av energimodellerad arkitektur
The interest in building low energy houses has increased along with the rising engagement inthe climate questions. With the advancing energy prices it is highly suitably for those whobuild and administer their buildings in long-term to build energy-saving houses. 40 % ofSweden?s total energy consumption constitutes of the energy in residences, therefore it iscrucial to take advantage of all the free energy as we possibly can. With crucial questions likequality of living and profit low energy building is a subject that concerns us all.Three proposals for apartment blocks are presented in this work on a real estate in Stockholm.Each proposal is developed through unique processes of design with the purpose to displaypossibilities to deal with the energy requirements of today and tomorrow through energybased architecture.The first proposal is an apartment block based on a traditional design process, the demands ofthe property owner and it?s affected by opinions from architects.
Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
LiDAR-bildanalys av flutings i södra Norrbotten : Kartering och datering av avvikande isrörelseriktningar
The aim of this study was to map and date glacial flutings with ice flows deviating from the predominating northwesterly ice flow direction in the southern part of Norrbotten County in northern Sweden, and also to investigate if parts of the glacial landscape are older than previously thought. The traditional view is that most landforms in the area were formed during the late Weichselian (W3). Analysis of the new high resolution elevation model (2 m grid) derived from laser scanning was performed after treating the data with a hillshade tool in ArcMap to reveal terrain features such as flutings. The analysis resulted in a map showing four main groups of deviating ice flows (N-S, NO-SV, SO-NV and S-N) and several westerly ice flows. The majority of flutings with deviating ice flows were found in low terrain.

Råda bot på öm fot
There is something magical about shoes?They can create an irresistible desire or be the one thing that we want to get rid of the most at the end of a long day. When people by shoes the chose more out of appearance rather then comfort. The result is a fact. The feet feel tired and soar after a couple of hours and the only thoughts are about the aching feet that firmly object to the way there being treated.
Förväntad och upplevd kunskap : En enkätstudie bland elever på Hotell- och Restaurangprogrammet
The purpose with my study was primarily to illuminate the students' expectations on gained knowledge during their studies at the upper secondary school Hotel- and Restaurant program, and to what extent these expectations were fulfilled. Secondarily, the purpose was to compare the students' expected and perceived knowledge with the program goals set by the Swedish government and the knowledge requirements expressed in a pilot study made by the Education council of the Hotel and restaurant business (UHR, 2007).I chose a quantative approach and I used an anonymous group enquiry among students at the Hotel- and Restaurant program at two different upper secondary schools to carry out my study.Tendencies in the result suggested that the students at the Hotel- and Restaurant program expected high knowledge level within the competence areas of Guest reception and communication, Cleaning and hygiene, Cooking of cold and hot dishes and Waiting. The expectations were not big within the areas Computers and Internet and Business economics and management.Fulfillment of expected knowledge tended to be high within the areas where the expectations were big. It might therefore be a good investment for schools to work on the student expectations to increase motivation within the low expectation areas.A confrontation of the tendencies in the result with the program goals and the competence requirements expressed in the UHR study, suggested that the upper secondary Hotel- and Restaurant education might focus some more the areas of Guest reception and communication, Beverages and Organization of banquets. Business economics and management should be given much more weight..
Energieffektiva värmesystem : Lösningen till att nå energimålen i byggbranschen?
Sweden has an environmental goal to achieve until the year 2020. To achieve this goal the construction business has to take an initiative to use the modern techniques that are available to lower the energy consumption I buildings. There?s also a debate going on today regarding the energy demands set by the Swedish government through Boverket, some communities throughout Sweden thinks that the demands are to low and have therefore set up own demands regarding energy in buildings.The possibility to construct energy-saving buildings is today very great, with energy-efficient heating-systems and dense climate envelope. The interest to raise energy-efficient buildings have also increased as a consequence that the population have become more aware about their impact on the environment.
Reflekteras det nya insatsförsvaret i utbildningen till officer? : En komparativ studie av det militärhistoriska ämnets kursplaner och inriktning i krigsvetenskap på Försvarshögskolan och West Point
This paper examines whether the American officer?s education at West Point and the Swedish officer?s education at the Military Academy Karlberg have adapted their history of the military art education in accordance to the new requirements of the Armed Forces and its focus on the operational defense. Sweden is evolving towards an operational defense and so is the United States. This in turn requires that training and education keep up with the changes. The National Defense College in Sweden do not focus the teaching of advanced history, which happened beforet he invention of the engine, in the officer?s training program, while the American education is rather advanced, with special focus on events taken place in the 19th century up to the Cold War.
