Biogas på Wapnö : Analys av framtida energisystem

Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.

Effect of vortex-processed water on tomato (Solanum lycopersicum) plants

This pilot study examined whether treatment with Vortex Process Technology (VPT) of the irrigation water used on tomato (Solanum lycopersicum) plants had any effect on plant growth. In a block experiment, with two blocks comprising 12 vases containing 1 L water and two tomato plantlets, treatment in which, nutrient solution was based on Vortex-treated water was compared with an control using untreated water. All vases were kept in a static aerated culture system in a daylight chamber for four weeks. The results showed that the effect of the two blocks exceeded the effect of vortex treatment in terms of leaf area and weight of fresh and dry matter. Plant height, stem width and internodal length were significantly different in tomato plants grown in Vortex-processed water compared with the untreated control.

Mass Ethics : En undersökning om att använda spelserien Mass Effect inom etikundervisningen i religionskunskapen på gymnasieskolan

Skolverket menar att populärkultur, däribland dataspel, är användbara verktyg för att nå elevernas livsvärldar i religionskunskapsundervisningen.Den här uppsatsen undersöker den religionsdidaktiska potentialen hos Mass Effect-spelen i gymnasieskolan utifrån följande frågeställningar:Får rätt och fel handling något utrymme i Mass Effect? På vilket sätt? Vad är rätt och fel i spelkontexten?Kan Mass Effect fungera som stödstruktur för att arbeta med stoff och förmågor som är en del av religionskunskapens etikundervisning och i sådana fall på vilket sätt?Spelkontexten utforskas genom en analys av hur spelens Paragon/Renegade-system bedömer olika handlingar. Systemet jämförs med plikt-, konsekvens- och dygdetiska förhållningssätt; dessa är etiska modeller som tas upp av styrdokumenten. En av spelens beslutssituationer granskas också utifrån en beslutsmodell och styrdokumentens etiska modeller bidrar här med teoretisk och kursplanemässig förankring.Undersökningen visar att flera av de områden som ska ingå i gymnasieskolans etikundervisning kan beröras genom att låta olika element i Mass Effect-spelen möta ämnets stoff. Processen verkar ur ett didaktiskt perspektiv både berikande för spelkontexten och illustrerar komplexiteten hos etiska modeller och fattandet av etiska beslut.

Risk för exponering av växtskyddsmedel i växthusmiljö

Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.

The close-down effect ? Det psykologiska kontraktet och belöningars betydelse för arbetsattityder vid nedläggning av verksamheter

Vid nedläggning av verksamheter har man i tidigare studier stött på det oväntade fenomenet close-down effect, att anställdas produktivitet ökar. Belöningar kan inverka på anställdas prestation då motivationen, enligt balansteorin, ligger i strävan efter jämvikt mellan belöning och arbetsinsats. Syftet med denna studie är att undersöka belöningars betydelse för anställdas arbetsattityder under nedläggningsprocessen, samt att undersöka om beslutet om nedläggning upplevs som ett brott mot det psykologiska kontraktet. En enkätundersökning och en prestationsbedömning genomfördes bland 275 medarbetare på ett tillverkningsföretag. Studiens resultat indikerar att ju högre anställdas förväntan om belöning är, desto högre är deras tillit till arbetsgivaren.

Effekterna av urbanisering, barksprickedjup och solexponering på lavfloran i sydöstra Sverige

Studies have shown that air pollution, as well as bark fissure depth and sun exposure of a tree can have an effect on lichen growth as well as abundance of lichen species. The aim of this study was to find out the relative importance of these factors. 211 oaks in south eastern Sweden were surveyed for presence of 17 lichen species, as well as the total number of lichen species. Half of the trees were situated in urban areas and half in the countryside. For each tree the bark fissure depth was measured and the sun exposure of the trunk was estimated.

Smakar konsumenter med ögonen En undersökning om förpackningens visuella attributs inverkan på smakupplevelsen av singelmaltwhisky

Packaging has had little impact in marketing literature. Research has focused on a single transaction approach. Lately researchers are looking at packages as a tool for brand building purposes. Thus, the focus is moving towards a multiple transaction approach, where packages can affect the consumer also after the purchase. For a range of goods extrinsic cues has been shown to have stronger effect on consumers' evaluation than intrinsic ones.

VILKEN STRANDVEGETATION BIDRAR TILL DET ORGANISKA MATERIALET I KUSTN?RA SEDIMENT? Kols?nkor/k?llor, nedbrytbarhet och eDNA sp?rning

Coastal sediments are important carbon sinks, storing organic matter and thereby helping to reduce the amount of greenhouse gases in the atmosphere. However, they can also act as carbon sources if the deposited organic matter decomposes rapidly, contributing to increased greenhouse gas emissions and global warming. Rapid decomposition partly depends on the degradability of the material itself. In this literature review, I examine which coastal plant species dominate different locations along the Swedish coast, based on coverage data from the ClimScape project (www.climscape.se). For the most dominant species, I investigated the type of organic matter they may contribute to the sediments and based on those results I qualitatively assessed which sites that may function as carbon sinks or sources.

Påverkande faktorer vid valet mellan vanlig el och grön el - en studie av hushåll i Göteborgsområdet

To be able to hinder the global warming the emissions of greenhouse gases, carbon dioxide foremost, must decrease. By switching to green electricity, it is possible to reduce the emissions from electricity producing sources.In 1999, Swedenergy conducted a study about whether or not Swedish households would consider buying green electricity. According to the study, about 75 percent were willing to buy green electricity. 40 percent of these were prepared to pay a premium for green electricity. However, according to the results from the study, only one percent actually bought green electricity, and since 1999, this proportion has merely increased slightly.

När stjärnor flyttar på sig : -En intermedial studie av läsprocessen som den relaterar till Codex, det digitala uppslagsverket i tv- och dataspelet Mass Effect

This study examines the in-game encyclopaedia Codex as it appears within the videogame Mass Effect. The purpose of this study is to analyse the Codex with emphasis on how the reading process is affected by the videogame medium. In this regard the study seeks to uncover what characterises the Codex as a fictional encyclopaedia, what it entails and how it interacts with the rest of the game. The theoretical basis of this study is derived from a combination of the writings of Wolfgang Iser concerning the process of reading, Jesper Juul's writings on the relationship between games and narratives, and the concept of intermediality as discussed by Hans Lund and Jørgen Bruhn.      This study is based on a close examination of the PC and Playstation 3 versions of the videogame Mass Effect, created by Bioware, with particular emphasis placed on the Codex. Mass Effect is a science fiction third-person shooter and RPG set in a future where mankind has begun interacting with aliens civilizations and colonising new planets.

Målgruppens betydelse för feedbackeffekten: En studie om hur en riktad varumärkesutvidgning påverkar feedbackeffekten i ett EMVs olika målgrupper

THE ROLE OF TARGET GROUPS IN FEEDBACK EFFECTSBrand extension is one of the most commonly used brand strategies since it reduces some of the risks involved in introducing a completely new brand. There are, however, several challenges associated with brand extensions. One of these challenges is the impact of a new brand extension on the parent brand image, which is known as feedback effect. Feedback effects are the changes in parent brand associations that are caused by a new brand extension, these effects can be both negative and positive. Several previous studies have investigated feedback effects and the antecedents of these effects.

?Ett spöke går runt Europa- kommunismens spöke? : En studie av religionsläromedel med fokus på den marxistiska livsåskådningen mellan åren 1970 och 1991

In the late 20th century the Soviet Union collapsed and the eastern European countries were freed from the communist Russian oppression. However, during the Soviet period Marxism was a recurring life stance in the Swedish textbooks for religious education in the gymnasieskola. Today the Soviet Union has collapsed, but the Marxist philosophy has had a huge effect on both single individuals and the modern society as a whole. Nonetheless, the Marxist life stance is nowadays often being replaced by other non- religious life stances in the textbooks of religious education.Therefore, this analysis is a hermeneutic study of the presentation of the Marxist life stance in textbooks for Swedish religious education. The purpose of the paper is to investigate how these textbooks portray the Marxist life stance, and to prove that the societal context and the individual author have an immense effect in the portrayal of both religions and life stances in religious education.

Den svenska kärnkraftsdebatten i skuggan av Fukushima : En studie i hur svenska kärnkraftsförespråkare i maktposition använder argumentation och auktoritet

Aim: The nuclear accident in Fukushima, Japan, raised global criticism against nuclear power. In Sweden, the criticism has not been very visible and the government now allows a renewal of the nuclear power plants. The purpose with the study is to have a closer look on how Swedes in position of power motivate their positive attitude to nuclear power and how they conduct themselves to each other and to their opponents. The rhetorical perspective will be in focus for the analysing.Method: Four different artifacts represented by Swedes in position of power having a positiveattitude to nuclear power were chosen. Three rhetorical theories (the rhetorical arena, stasis andethos, pathos and logos) were used with the research question in focus.Result & Conclusions: The analyses resulted in conclusions about the strategies used by the participants such as: the importance of contexts, meaning for example that The greenhouse effect legitimizes nuclear power as a source of energy with important benefits.

Background: 2007 there was 42 000 fall related accidents in Sweden and they are expected to increase the next few years. Fall among elders results in both increasing economically costs and suffering, but they can be prevented. For example has physical exercise shown an increasing effect on the risk for falls. Aim: The aim of this literature review was to investigate what influence Tai Chi has on the risk for falling among elder. Method: A literature review was conducted where eleven scientific articles were analysed with inspiration of the content analysis.

Gaspotentialen i en deponi, idag och i en framtid :

Deposited waste material degrades within a short period in anaerobic environments. The methane gas that is formed provides a harmful contribute to The greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas. In this thesis the amount of produced methane gas at the landfill at Örebro has been calculated. Estimations have also been made of the amount of methane gas that might be produced in the landfill in the future.
