Den globala uppvärmningen i skolans läromedel : En jämförande studie av sponsrade och förlagsutgivna läromedel

Today the talk about global warming and climate change are on top of the public agenda. There for schools and schoolbooks also debate the issue of global warming. A newcomer on the school stage is the sponsored school materials that studies show to be a growing phenomenon. In a debate like that of global warming which is filled with uncertainties and so much political and economic interest, I find it interesting to study how these schoolbooks talk about the issue.In my study I have tried to analyze and compare how school materials for primary school discuss the phenomenon of global warming. I have compared two different types of schoolbooks.

Påverkan på energianvändning och termisk komfort vid reglerinstabilitet

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

Ny världsordning, nya utmaningar? En teorianvändande studie om förhållandet mellan USA och Europa sedan Kalla krigets slut

In this thesis I discuss and analyse the relationship between USA and Europe since the end of the Cold War. Many authors claimed that the Soviet threat was the glue that kept the continents together. Now that threat is gone and new challenges have risen. In what way has this relationship been influenced by the new challenges this new era stands for? By doing a case study and by using two quite different theorists, John Mearsheimer an offensive realist and Joseph Nye who is a liberal institutionalist, I?ll try to show how for example September 11, anti-amerikanism and NATO can be explained and understood.

UPPFATTNINGAR AV ETT NYTT RYSSLAND?V?RNKRAFT ELLER STRATEGISK TIMEOUT? Inverkan av Rysslandsuppfattning p? svensk-finsk nedrustning 1995?2009

This study investigates Swedish and Finnish official perception of Russia following the Cold War. This is aimed at categorizing changes in perception of Russia over time and assessing the impact of perception on defense policy. The study uses a comparative method where the contents of three foreign policy reports of Sweden and Finland respectively are analyzed according to dimensions based in image theory. Results show that Swedish and Finnish perceptions of Russia are overall similar between the reports being compared, except for Finnish perception of Russian relative power being significantly greater. Changes in Swedish and Finnish official perception do not clearly correlate with changes in defense policy.

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.

Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Just war teorin och de nya krigen -en möjlig kombination?

In the political world of today the discussion of Just wars are very present, since the international law and the UN Charter provides certain rules about when it is justified to go to war (jus ad bellum) and how a justified war should be conducted (jus im bello). The discussion about jus ad bellum and jus im bello derives from the theory of Just war. Both in international law and the Just war theory, focus is on interstate wars were the actors are two sovereign states. Since the end of the Cold War there has however been a change in the way wars are conducted. From interstate to intrastate warfare, where the government in most cases no longer has the monopoly over the warfare.According to these facts, my conclusion is that the Just war theory has to expand and incorporate a focus on the human rights in order to be able to meet the new standards of the new wars.

Förnybara bränslen är lösningen, vad är problemet? En maktanalys av den svenska dagordningen för förnybara bränslen

The aim of the thesis is to examine how central collective actors in the Swedish subsystem of renewable fuels use their positions of power and influence to their own specific interests and needs. In particular the thesis looks at the problems of climate change and oil scarcity and how renewable fuels are described as a potential solution. Using agenda setting theory and Steven Lukes three dimensions of power as a framework, five actors are examined and analysed. The study has been done in two parts. In the first part policy documents are analysed concerning the actors general stance towards renewable fuels, and how this is communicated to the media, politicians and public.

Frisk med probiotika? -Skyddar eller lindrar ett dagligt intag av probiotika mot förkylning, feber och influensasymtom?

Bakgrund: I Sverige drabbas vuxna av i genomsnitt en till två förkylningar per år och barnminst dubbelt så ofta. Totalt betalade Försäkringskassan ut 4 656 667 vab-dagar (vård avbarn) under år 2010. Probiotiska bakterier i tarmen konkurrerar med sjukdomsframkallandeorganismer och reducerar dess förekomst i tarmfloran. Om probiotika kan användas för attminska eller åtminstone förkorta sjukdomstiden skulle det vara en enkel metod till en relativtlåg kostnad vilket sparar tid, pengar och lidande för alla parter.Syfte: Syftet med denna systematiska översiktsartikel var att undersöka huruvida ett dagligtintag av probiotika skulle kunna skydda mot eller lindra förkylning, feber ochinfluensasymtom.Sökväg: Litteratursökning i databaserna PubMed och Scopus har genomförts. Sökord somanvändes i olika kombinationer var: probiotics, effect, common cold, fever, flu, influenza,respiratory diseases, lactobacillus och bifidus.Urvalskriterier: Inklusionskriterier vid litteratursökningen var humanstudier i RCT-form därinterventionen varit dagligt bruk av probiotika.

Regeringens miljösatsningar och deras förhållande till en hållbar livsstil hos det svenska folket : En studie av biståndssatsningars påverkan på hållbar livsstil i givarlandet

Swedish government aid is divided into three main themes: democracy and human rights, the environment and climate, and gender equality and women's role in development. These three themes in aid are considered by the government to be vital in order to fight poverty and create fair and sustainable development. This study will examine two of the four focus areas designated under the theme of "environment and climate". The study observes the relationship between projects in energy and water and how it promotes a sustainable lifestyle. A survey on environmental habits will be conducted.

Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde

Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.

It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency..

World of Warcraft : En virtuellt social värld

In today?s modern society with high-speed connections covering the globe people are more than ever finding themselves gazing into the cold lights of the computer screen. On the other side a strange and exciting world yet to be explored awaits. Many are those who spend hour after hour running over green hills swimming in vast blue oceans in the lands of Azeroth, the playfield in the MMORPG game World of Warcraft. In media we often read and hear alarming reports on players stuck in this virtual world, ceasing to play a part in the real world.

Perceptions of domestic solar systems : a study on non-adopter views of a new technology

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

Sverige 2112 : Ett narrativ om hur arkitekturen kan utvecklas om världen går igenom stora förändringar på grund av klimatförändringarna. En linjär och vertikal stad.

Om världen till följd av klimatförändringarna blir mycket varmare kommer förutsättningarna för hur vi planerar städer, infrastruktur och jordbruk helt att vändas upp och ner. De delar av världen som idag står för världens livsmedelsproduktion kommer vid bara några graders förändring bli obrukbara som betes och odlingsmark. Dessa förändringar kan komma att starta konflikter, och stora flyktingströmmar som tillsammans med förändrade klimatzoner helt kommer att rita om världskartan. i Skandinavien är det då troligt att vi behöver bygga samhällen och städer för miljontals nya immigranter, och detta samtidigt som vi befinner oss mitt i den mest fruktbara jordbruksmarken i världen. Om hundra år måste vi dessutom, oavsett detta, dubbla livsmedelsproduktionen globalt sett.Vårt samhälle blir allt mer rörligt och infrastrukturen utvecklas i allt snabbare takt.
