EN FALLSTUDIE OM URBAN VINDKRAFT VID ALBANO
The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.
Pilgrimsvandring som verktyg f?r f?r?ndring. Pilgrim?s Walk for Future?s aktualisering av pilgrimsteologin under nyliberala villkor
In the essay the author examines how pilgrimage can be used as a tool to radicalise democracy in a late modern society marked by neoliberalism. Applying a dialectic perspective on social movements the essay puts forward how the pilgrimage movement Pilgrim?s Walk for Future, administrated by Church of Sweden, is working in line with the historical pilgrimage theology - a modern critical ecclesiology- to mobilise political action to prevent climate change. The result of the study shows how PWFF meet the neoliberal hegemony with a mobilisation of alternative values beyond the order of capitalism, in line with Christian theology and tradition. The mobilisation is made possible by new forms of identifications with oneself and the social world that meet a modern power/knowledge- regime based on rational thought, and which questions norms and practises by paying attention to their negative effects on nature and on human life in general.
Energieffektivare torkning i diskmaskiner genom ny torkmetod : Utvärdering genom praktiska försök och simuleringar
Världens energiförbrukning ökar ständigt. Detta ger upphov till stora miljöproblem där klimatförändringen är ett av de största problemen. Hushållens energiförbrukning står idag för en betydande del av den totala energianvändningen. Det är därför viktigt att effektivisera hushållens energianvändning för att reducera deras påverkan på miljön. Vitvaror, som står för en stor del av hushållens energianvändning, har en stor potential att energieffektiviseras.

Etisk utvärdering av chefers ledarskap : Vilka etiska principer bör ligga till grund för utvärdering av chefers beteende?
A reform of higher education in Sweden in 1993 led to stiffer competitive climate among educational institutions. The reform meant that educational institutions now had the opportunity to plan their curriculum autonomously. Prior to the reform educational planning was restricted to the Swedish government. The new rules spelled a greater opportunity for educational institutions to profile themselves based on their educational offerings. The higher degree of competition means that marketing becomes increasingly important when recruiting new students.
Havsnivåhöjningens påverkan på Gotlands kust och strandängar år 2100
Den globala havsnivåhöjningen är en direkt följd av den globala uppvärmningen ochkommer i framtiden påverka stora områden i kustregionen. Syftet med detta arbete äratt öka förståelsen samt se hur Gotlands strandängar samt kustområden kan påverkas avhavsnivåhöjningen år 2100 och se vilka eventuella följder detta kan leda till. Metodernasom har använts är GIS-analys och litteraturstudier. Höjdmodeller med olika upplösningjämfördes även för att undersöka vilka som lämpar sig till en liknande analys införframtida studier. Resultatet visar att vid en havsnivåhöjning på 1 m kommer 97 % avstrandängarna försvinna och vid en havsnivåhöjning på 2 m försvinner 99 % av degotländska strandängarna.
Mannen, myten... Stereotypen? : En kvalitativ innehållsanalys av hur manliga stereotyper konstrueras i tidningen Cafés reklamannonser
The discussion about gender and ideals shown in mass media is a subject of great importance for the society in general. Media is playing an essential part when it comes to establish standards and values and we are constantly exposed to all types of impressions, whether we are aware or not. It is therefore of great importance that we understand how stereotypes are built and to gain a deep knowledge that would enrich the area of Media and Communication Studies.The aim and focus of this study was to analyze how male stereotypes is communicated in print advertising and how visual means of expressions helps to construct the masculinities shown. From a semiotic analysis of seven print adverts appearing in the Swedish lifestyle Magazine Café were we able to gain a thorough understanding about how male stereotypes are communicated and built.The result showed that different kinds of stereotypes are in fact used but it is still a hegemonic masculinity that is predominating. Traditional male characteristics are still in use but we were able to see strong indications of effemination, sexualizing and objectifying.
Värmeväxling med torkluft från Valmets pilotmaskin TM1 : Återvinning av spillvärme vid torkning av mjukpapper
Idag ställs stora krav på företag att vara miljömedvetna och resurseffektiva i sin verksamhet. Vid mjukpapperstillverkning används stora energimängder och inom industrin har det under många år funnits en strävan att energieffektivisera processer och att tillvarata spillenergi, bland annat genom värmeåtervinning. Valmet Tissue Technology Center i Karlstad har idag en pilotmaskinen utan värmeåtervinningssystem. Den här undersökningen gjordes i syfte att ta reda på hur stor återvinningspotentialen är för värmeväxling i pilotmaskinens torkpartier, bestående av Yankeekåpan och TAD-cylindrarna. Tre maskinkoncept undersöktes: DCT®, NTT? och TAD.
Solceller pa? Uppsalahems fastigheter : Ekonomisk potential fram till 2030
Uppsalahem is the leading housing corporation in Uppsala with its over 160 real estate properties. Uppsalahem is owned by the municipality of Uppsala, which has a climate and energy goal that aims for 100 MW of solar energy to be installed in Uppsala by 2030. The 100 MW goal, combined with Uppsalahem?s environmental policy, is a strong incentive to investigate the possibility of installing PV modules on the many available roof areas that Uppsalahem possesses. The objective of this thesis is to create a foundation for future decisions regarding PV systems for Uppsalahem.
Parasitering på en expanderande art : har kartfjärilen undkommit sina naturliga fiender?
Warmer climate is a driving factor to species expansion northwards. Expansion to new areas can result in escape from natural enemies, resulting in reduced levels of mortality and thereby potentially increasing the rate of expansion. The most important parasitoid species attacking butterfly larvae belong to the families Tachinidae, Ichneumonidae and Braconidae. The aim of this thesis was to investigate parasitism and difference between populations in established area and newly colonized area for the European map butterfly, Araschnia levana, in order to examine if the butterfly has escaped from some natural enemies. In 1982 the first European map butterfly was observed in Sweden and has now established up to middle Småland.
"Det är alldeles för mycket sport inom idrotten" : En studie av svenska sportchefer
Authors: Lars Johansson & Johan PetterssonTitle: ?There is way to much sports in the athletics? ? A study of Swedish sportsFootball has gone from being a hobby and a popular pastime into a billion-dollar industry, and clubs around Europe are therefore operated more and more like regular companies. Sweden's position in the UEFA rankings is a modest 23 rd place, behind nations such as Austria, Switzerland and Belarus. The economic climate in Sweden is often highlighted as a strong factor. When we started our study we agreed that this could be a major contributing factor to this relatively modest rank, but believed that there were also other factors that played a big role.
Följdeffekter av olika användningssätt för vedråvara : en ekonomisk studie
Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased.
As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.
Karlstad och vattnet : En studie av hur förhållningssättet till översvämningsrisk har förändrats i Karlstads kommun sedan 1950-talet
The location on the river delta of Klarälven, adjacent to lake Vänern, makes Karlstad one of the Swedish cities where a significant flood risk is present. The city has several major floods in its memory which has caused great material damage and economic losses, the latest of which occurred in the winter of year 2000/2001. The purpose of the study is to examine how the approach to flood risk has changed in the municipality of Karlstad since the 1950s, and how this change has affected the current situation regarding the city's vulnerability to flooding. To investigate this, a document analysis was conducted, where key documents in the media and from the municipality of Karlstad was studied. Furthermore, an interview study was conducted with respondents who currently are employed or previously have been employed in the municipality of Karlstad, who in various ways work with issues of flood risk. The result of the study shows that several changes have taken place since the 1950s in terms of the municipality's approach to flood risk, which for instance has led to preventative measures being taken to a greater extent than previously in the physical planning.
Dikesavståndets inverkan på såtid och skörd
All arable land in Sweden need a proper drainage for an effectively agriculture to take place. Of all arable land in Sweden, about 50% is naturally drained and 50% need artificial drainge. More than half of the tile drained area is in need of new drainage or renewed drainage. A good drainage improves farming and crop growth and increases the opportunity to achieve a high and safe harvest level. Future climate change and agriculture size rationalization will increase the need for good drainage.
In this paper, two trials with three drainage distances, performed at Lanna experimental station, were analyzed using a mixed linear model.
"Som en pusselbit som passar överallt" : En kvalitativ studie om hur gymnasieelever upplever kreativitet på psykologilektionerna
In the nineties, policy makers highlighted the importance of creativity in education in order to nurture entrepreneurs in our society, thus the purpose of this study is to investigate high school students´ experience of creativity in psychology classes. The results are based on qualitative data from four semi-structured interviews with Swedish high school students who study psychology. The conclusions are that the respondents perceive psychology as a very creative school subject in which they can give personal experience as examples, they can give alternative explanations and solutions to problems, and that there are no right or wrong answers which means that they feel encouraged to self-reflect. The teacher is important as the respondents experience her as open, tolerant, and moreover, that she varies the classes, which contributes to a good classroom climate. The respondents also experience a certain degree of freedom when they feel involved and are allowed to influence their education.
