Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation

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.

Att möta utmaningen - En diskursanalys av europeiska staters inställningar till utsläppsreduktioner

The European Union is a self proclaimed leader in the field of climate change and has a common target for reductions of greenhouse gas emissions. In spite of this, there are great differences between the member states capacity and dedication to the cause of implementing the Unions climate policy and reduce their emissions. The purpose of this thesis is to contribute to an understanding of how different European states construct their identity in the context of climate change Mitigation. By analyzing national documents from three European states and using tools deriving from discourse analysis, I aim to illuminate differences and similarities in their rhetoric. The result is that due to the states relationship to the European Union and the United Nations, there are great similarities in the way they construct Mitigation and their identity.

Nya PBL- vad hände sen? : En fallstudie kring den reviderade lagens påverkan på det kommunala planarbetet med fokus på klimataspekten

The purpose of this paper is to examine how the revised Planning and Building Act (SFS 2010:900) have influenced the comprehensive planning in Swedish municipalities. A focus is directed at examining how the new law regulates a greater consideration to climate aspects and the what consequences this results in regarding the implementation of the law in Swedish municipalities comprehensive plans.The paper is a case study, containing both quantitative and qualitative methods. The case study is based on three municipal comprehensive plans. Based on quantitative material three municipalities have been selected to constitute the sample of this study. These municipalities are A?lvsbyn, Sollentuna and Olofstro?m.

Samband mellan virulensgener och VTEC-infektioner : Riskklassificeringssystem för VTEC

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two Mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

Opportunities for improved environmental sustainability of a wine producer in South Africa : natural resource management and climate change adaptation and mitigation

South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.

Radialtätning till Retarder

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and Mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Klimatsmart vardag : en fallstudie av projektet ?Klimatpiloterna i Askersund och Laxå?

Denna uppsats är en fallstudie av ?Klimatpiloterna i Askersund i Laxå?, ett projekt som har velat lära människor hur man kan reducera sina koldioxidutsläpp. Arbetet bygger på semistrukturerade intervjuer med projektdeltagarna och syftet är att beskriva hur de får vardagen att fungera när de samtidigt försöker minska sin klimatpåverkan. En viktig teoretisk utgångspunkt är att vardagen är praktisk och till stor del består av oreflekterade rutiner. Begreppet risksamhälle används för att belysa hur informanterna tack vare klimatexperter, i detta fall projektledarna, blir medvetna om både klimathotet och vilka förändringar de bör göra i sina vardagsrutiner.

Kvalitetsgranskning av skadeförebyggande åtgärdsförslag i miljökonsekvensbeskrivningar

I en miljökonsekvensbeskrivning, MKB ska en beskrivning av planerade åtgärder ges för att undvika, minska eller avhjälpa skadliga verkningar, då projektet antas medföra betydande miljöpåverkan. Eftersom det upptäckts allvarliga brister för skadeförebyggande åtgärder i forskningsrapporter utomlands, var det intressant att undersöka åtgärdskvalitén i några svenska MKB. Svagheter och styrkor i skadeförebyggande åtgärder i 6st MKB för 2st markkabelanläggningar i Sverige undersöktes. Metoden för undersökningen var två fallstudier som jämfördes mot varandra och analyserades mot teorier. Resultatet visade att kvalitén på det undersökta materialet var övervägande bra, jämförelsevis mot de forskningsrapporter som visat på bristfälliga åtgärdsförslag utomlands.

Design av Riskdatabas : En studie för effektivare hantering av risker

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

The effect of additional nitrate and sulfur in the diet on the methane production in cattle

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

Ont begär : horsbrotten i Fryksdals härad och Jösse härad i Värmland under mitten av 1600-talet

The 17th century was a time of change in Sweden. During the century many of the Swedish laws were altered. In the beginning of the 17th century this alteration resulted in a more severe sentence for most of the committed crimes, but a Mitigation of the sentence for some of those crimes was effected in the middle of the 17th century. The aim of this study is to see how two local courts in the judicial system during the mid 17th century in Sweden treated adultery, and those who committed the crime against the background of what the law regarding adultery stipulated. The source material used are court records from Fryksdals hundred and Jösse hundred in western Sweden, and laws regarding adultery during the 17th century.This research shows that the laws regarding adultery were in themselves not gender specific, and their main concern was the marital status of those involved.

Logopeders samtal med närstående till en person med afasi : En samtalsanalys

I institutionella samtal såsom närståendesamtal mellan en logoped, en närstående till en person med afasi och personen med afasi råder en asymmetri gällande maktförhållandet. Asymmetrin som uppstår i det institutionella samtalet kan innebära att samtalsdeltagaren med minst makt upplever ansiktshot. I samtal ses förståelse som en dynamisk process och när förståelsen innebär ett problem i konversationen störs den pågående aktiviteten. Mottagaren kan lösa problemet som uppstått genom att ge talaren en candidate understanding. Hur kommunikativa strategier används i närståendesamtal är ett relativt obeforskat område och ett viktigt område då närståendesamtal är en vanligt förekommande för logopeder.

Kustnära ekosystem som skydd mot naturkatastrofer : en litteraturstudie från ett riskhanteringsperspektiv

Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster Mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

Social and economic consequences of wolf (Canis lupus) establishments in Sweden

Wildlife contributes with many benefits to humans but also brings economic costs. From being eradicated in Scandinavia the grey wolf (Canis lupus) is returning to South-Western Sweden and people are not used to its presence. In Scandinavia carnivores have to co-occur with humans in a landscape used for many different interests. Consequences of wolf establishments are e.g. competition for moose, depredation on sheep and attacks on hunting dogs.
