Thermometry using OH laser-induced fluorescence excitation spectra: A feasibility study

In this thesis, rotational spectra, acquired through laser-induced fluorescence (LIF) on the OH-radical, were used to evaluate temperatures in different combustion environments. By comparing experimental spectra with theoretical ones of known temperature, the temperature can be determined. A MATLAB-code has been developed that evaluates temperature by comparing experimental spectra with a library

Användning av 3D-skrivare i grundskolan för barn med synnedsättning

Syftet med arbetet var att undersöka om det går att använda 3D-skrivare för att skriva ut modeller i pedagogiskt syfte för barn med synnedsättning. Ett antal modeller skrevs ut till två barn med blindhet som gick på två olika grundskolor i Skåne. Båda eleverna gick i vanliga klasser men hade i skolan extra stöd i form av en resursperson. De 3D-utskrivna modellerna anpassades till deras vanliga und

Early life and its implications for astrobiology : a case study from Bitter Springs Chert, Australia

Forskning kring tidigt liv möter svårigheter utöver de som forskning kring senare liv ställs inför. På grund av att de tidigaste bergarterna inte finns bevarade har viktig information om jordens tidiga förhållanden för evigt gått förlorad. Dessutom var de tidigaste livsformerna små och morfologiskt enkla, vilket betyder att abiotiska pseudofossil lätt kan infiltrera fossilarkivet. Ett centralt temEarly life research faces additional challenges than those of the study of later life forms. Due to the de-materialization of the earliest rocks, valuable information about the early Earth is forever lost. Furthermore, early life was small and morphologically basic, effectuating abiotic pseudofossils to infiltrate the fossil record. A central theme is the close connection early life research share

Webboptimering, ett riskfyllt äventyr?

En grundförutsättning för att lyckas driva en framgångsrik verksamhet online, är tillgången till en hemsida som tydligt reflekterar dess användningsområde och som konverterar besökare till kunder. Sedan länge har webbutvecklare varit införstådda med fördelarna av gränssnitt utvecklade utifrån besökares preferenser. Numera finns digitala verktyg som möjliggör kontrollerade experiment på hemsidor dä

Hållbar textilhantering

I denna magisteruppsats, med titeln "Hållbar textilhantering", undersöks ett urval av olika affärsmodeller och strategier närmare vad gäller ett hållbart koncept och flöde inom textilförbrukningen och hur detta fenomen varierar och ger uttryck för sig idag. Uppsatsen utgår från teori kring CSR, affärsmodeller inom hållbar utveckling, samt från hur textilier produceras tills att de blir sThis master's thesis, entitled "Sustainable Textile Management," examines a range of different business models and strategies more closely in terms of a sustainable concept in textile consumption and how this phenomenon varies and is expressed today. The thesis is based on the theory of CSR, business models in sustainable development, as well as how textiles are being produced until

Miljöeffekter av jordbruksinvesteringar i Etiopien

Sammanfattning Efterfrågan på jordbruksmark har under senare år ökat dramatiskt. De huvudsakliga bakomliggande drivkrafterna till denna är jordens växande befolkning, produktivitetsminskning av tidigare fertil jordbruksmark, ökad efterfrågan på biobränsleproduktion samt de stigande matpriserna. Dessa faktorer har resulterat i att ett stort antal nationer och företag investerar i jordbruksmark utanDemand for agricultural land has increased dramatically in recent years. The drivers behind this increase are the world’s growing population, the decrease in productivity in former fertile agricultural land, the increased demand for bioenergy production and the rising food prices. These factors have led to an increasing amount of companies and nations that have made investments in agricultural lan

The Granger causal relationship between energy consumption and economic growth for eight European countries

Motivated by the rising importance of today’s environmental issues and more specifically the role of energy conservation policies, the current study investigates the Granger causal relationship between energy consumption and economic growth in eight European countries. Using a large dataset that overall spans from 1800-2009 the study employs the Toda-Yamamoto procedure and cointegration analysis w

Stepping outside the comfort zone : implementing electricity-saving practices on the municipal level taking a practice theory perspective

In this thesis, the effectiveness of municipal climate policies aiming to influence citizens’ electricity consumption to address the sustainability challenge of climate change was investigated. The cases of two policies of the city of Frankfurt am Main, the electricity-saving counselling and electricity-saving premium, were considered. A qualitative research approach was taken, by conducting twent

Flygbildsbaserad förändringsstudie inom skyddszoner längs vattendrag

Det skånska landskapet har sedan 1800talet varit starkt påverkat av lantbruket. Åar har rätats ut, fördjupats och kulverterats, vilket i kombination med en ökad gödsling har lett till ökat näringsläckage som gett konsekvenser i form av minskad biologisk mångfald och övergödning. Ett sätt att minska övergödningen är att anlägga vallbesådda skyddszoner längs vattendrag. Lantbrukare kan få ersättningThe landscape of Scania in southern Sweden has been heavily influenced by agriculture since the 1800s. Rivers have been straightened, deepened and culverted which in combination with increased fertilization has had consequences such as loss of biodiversity and eutrophication. One way to reduce eutrophication is to construct grass seeded buffer zones along watercourses. Farmers can receive compensa

The Jade Road

The term the 'Jade Road' is very hard to find in English literature yet the Chinese term '玉石之路' exists within Chinese archaeological and cultural articles (and even in business and travel magazines) as a prehistory to the 'Silk Road'. Why has this term, 'Jade Road', escaped translation and explanation in English material and what facts and theories exist about it? T

Hur tar sig storvilt fram i landskapet? - En utredning av den biologiska infrastrukturen för storvilt mellan grönområdena i Borås Stad

The infrastructure and the traffic that it brings affect wild animals and thus the entire biodiversity. The human built up network of cities and connecting roads are major barriers for many species in the natural world, making it harder for them to move through the landscape. The more roads in a landscape, the more fragmented it gets and with it important habitats get degraded. Long-term effects f

Parental Education and Child Human Capital: Evidence from Indonesia

This paper exploits one of the largest school construction programs on record, which took place in Indonesia in the 1970s, to estimate the causal effect of parental education on child human capital. I use variation in program exposure as an instrument for maternal and paternal length of schooling. The results show little evidence of a causal impact of parental education on child health and skills

Two Millennia of Lexical and Typological Change in Western Europe - a quantitative approach

This thesis aims to examine the lexical and typological change found in the Western European language families of Germanic, Romance and Celtic over the last two millennia. The method used was to create one lexical and one typological database and the data was analysed according to etic grids. Tree models were generated from the results of the databases and the groups found in the tree models were

Trade and the Environment in Central America

During the last decades, the policies of trade liberalization and export promotion have been crucial to Central America's economic growth. Because of the linkages between trade and the environment, this dramatic shift in Central America’s trade patterns could have important implications for the environment and use of natural resources. This paper looks at the dynamics between trade and the env

Ekosystemtjänster i svenska agroforestrysystem

Lantbruket har en påverkan på miljön och därmed jordens ekosystem. Det är viktigt att lantbruket utvecklas på ett sådant sätt att dess påverkan på ekosystemen bli så liten som möjlig. Processer i ekosystemen ger upphov till ekosystemtjänster. Det är ekosystemtjänsterna som ger oss mat, reglerar klimatet, gör näringscykler möjliga med mycket mer. Ett hållbart lantbruk bör därför inte påverka ekosysAgriculture has an impact on the environment and therefore the ecosystems. It is important that the agriculture is managed in such a way that the impacts on the ecosystems are as small as possible. The processes in the ecosystems give rise to ecosystem services. It is the ecosystem services that give us food, regulates the climate, fuel nutrient cycles and a lot more. A sustainable agriculture sho

On track for equitable mobility in the suburbs : the case for a transition back to rail service on the former West Chester Rail Branch Corridor in the Greater Philadelphia area

In many urban spaces in the United States, the personal vehicle continues to shape the landscape in unsustainable ways that prioritize the economically and socially dominant groups in society and cater to urban sprawl. Equitable access to density-promoting public transportation is often marginalized, creating transportation challenges for economically and socially disadvantaged groups. Throughout
