Bike safety among children in Sweden

Detta examensarbete undersöker den nuvarande situationen för cyklande barn i Sverige. Den undersöker ett internationellt och historiskt perspektiv, vilket ger jämförbar information om säkerheten för cyklande barn i andra samhällen. Variationer över tiden i totalt cyklad längd studeras och dess inverkan på säkerheten är noga övervägd. Minskade cykelnivåer visar sig vara en avgörande faktor för säke

A future introduction of biohydrogen to the Swedish energy system

Biovätgas - nuvarande utveckling kan tala för en framtida integration i det svenska energisystemet Ett stort fokus ligger idag på att minska våra utsläpp av växthusgaser. Vätgas är sett som ett intressant alternativt bränsle i sammanhanget eftersom dess förbränning bara ger upphov till vatten. Vad färre vet är att produktionen av vätgas orsakar desto större utsläpp av växthusgaser eftersom den of

Photo-chemical reactivity of dissolved organic carbon in subarctic lakes from northern Sweden

Dissolved organic matter (DOM) is the major absorber of sunlight in most natural waters and a critical component of the carbon cycle in aquatic systems. The photochemical decomposition of DOM can have a significant impact on the landscape-atmosphere carbon exchange. However, little is known about how changing characteristics of DOM due to water browning (allochthonous inputs of DOM from terrestriaThe photochemical decomposition of the dissolved organic matter DOM can have a significant impact on the landscape-atmosphere carbon exchange. However, little is known about how changing characteristics of DOM due to water browning (allochthonous inputs of DOM from terrestrial sources) affect the photochemical processing of the DOM. A shift from in situ self-produced (autochthonous) DOM to allocht

A study of the legal protection for elderly employees - A narrative and comparative study between the Kingdom of Sweden and the People’s Republic of China

Äldre anställdas ställning på arbetsmarknaden är onekligen osäker. I detta arbete försöker jag att räta ut och förstå hur äldre arbetstagare är skyddade på arbetsmarknaden genom att undersöka hur gällande rätt är designat. Detta görs genom en komparativ studie mellan Sverige och Kina, där en rad olika undersökningsområden kopplat till anställningsskydd för äldre bearbetas. Arbetet berör och förkla

Implications of ice-bedrock dynamics at Ullstorp, Scania, southern Sweden

The field of Quaternary science has, through a long history of high-quality research, produced a vast record of evidence regarding ice sheet dynamics. Consequently, our understanding of such processes and their effects are well understood. However, historically the predominant focus has been of a loose sediment perspective, which has resulted in limited insight into ice-bedrock dynamics. This is i

Possibilities and challenges for expanding the electric vehicle adoption: A case study of Swedish consumers’ perception of electric vehicles

Electric cars are by many considered a sustainable solution to the ever-growing demand for road vehicles and fuel. The transportation sector is responsible for almost a third of the total greenhouse gas emissions globally and approximately 80% of these emissions can be attributed to road vehicles. Thus, there is an urgent need for a shift away from fossil fuels in the sector. While the consumer in

Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden

Den globala uppvärmningen har stora effekter på det subarktiska ekosystemet i norra Sverige. De ökande temperaturerna i dessa ekosystem har lett till ett tinande av permafrosten i marken. Permafrosten innehåller stora mängder kol och när tjälen i marken försvinner blir detta kol tillgängligt för nedbrytning av mikrober i marken. Denna nedbrytning av kol i kombination med en våtare mark leder till The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. The combination of the high microbial activity and overall wetter soils may cause anoxic conditions and in turn methane (CH4) a

Global Rankings in Swedish Universities : A Qualitative Study of Knowledge Management Practices

During the past two decades, the higher education sector has undergone rapid changes as a result of which many higher education institutions (HEIs) find themselves being compared to other institutions. Global rankings have become the prime mechanism for providing such comparisons. How nations and their HEIs respond to the developments in the higher education sector is context-specific. There is a

How brownification and eutrophication effects a drinking water source – with Lake Bolmen, Sweden, in focus

Kan förhöjda halter av näring och humusämnen från jordbruksmark och skog påverka kvalitén på vårt dricksvatten? Försämrad vattenkvalitet, ökade farliga algblomningar och minskad biodiversitet kan vara framtiden för våra vattendrag, på grund av de miljöförändringar vi står inför idag. I detta projekt undersökte jag hur framtiden kan se ut för en av våra sjöar vi får dricksvatten från här i söder,The ongoing human impact in form of deforestation, urbanization and intense agriculture is affecting the natural hydrology and our freshwater lakes negatively. Both eutrophication and brownification has seen to increase with the ongoing environmental change which can potentially have large impact on our freshwater ecosystems. Using a mesocosm experiment, this study investigates the individual and

A re-investigation of hummocky moraine formed from ice sheet decay using geomorphological and sedimentological evidence in the Vomb area, southern Sweden

Glaciala sediment- och landformskonstellationer har länge använts för att rekonstruera inlandsisens dynamik och rörelser under Kvartärperioden, specifikt så för den senaste glaciationen i norra Europa och södra Skandinavien. En sådan sediment- och landformskonstellation är ’småkullig morän’, som tidigare har använts som en övergripande och beskrivande term starkt associerad med dödisutsmältning ocGlacial sediment-landform assemblages have long been used to reconstruct the dynamics of ice sheets throughout the Quaternary time period, particularly so for the period of the last glaciation in northern Europe and southern Scandinavia. One such sediment-landform assemblage is hummocky moraine, which has previously been used as an all-encompassing descriptive terminology strongly associated with

More Than Just Money - The Experiences and Perceptions of Remittance-Sending from the Perspective of Syrian Migrants Settled in Sweden

This study explores the qualitative aspects of remittance-sending. The central premise is that remittances are a concept that is socially embedded and therefore needs to be explored beyond its fiscal characteristics. The research contends that there is a gap in qualitative research where remittance-senders are concerned and argues that it is essential to understand the experiences and perceptions

Indoor relative humidity levels and perceived symptoms in elderly homes in Sweden during winter season

For the sense of well-being and human health, a pleasant indoor environment is essential. Today, people spend about 90 % of their time indoors, meaning that they can be significantly affected by the buildings in which they spend most of their time. Older people are bound to spend more time indoors and also as they belong to the most sensitive age group, their indoor environments as elderly homes m

Structural investigation of ductile deformations across the Frontal Wedge south of Lake Vättern, southern Sweden

Deformationszonen kallad ”Frontal wedge” är ett system av N-S branta och vertikala deformationszoner i gränsen mellan Svekonorvegiska och Sekorareliska provincen, i södra Sverige. Ursprung av dessa strukturer är inte fullt förstått och under de senaste årtiondena har endast ett fåtal undersökningar gjorts på dessa deformationszoner. Det finns flera olika tolkningar och modeller för bildandet av st

Transformative change through local networks - A case study on the ‘Local Roadmap for a Climate Neutral Building & Construction Industry 2030’ in Malmö, Sweden

With rapid urbanization and an increasing share of anthropogenic greenhouse gas emissions from cities, low-carbon urban transformations are critical for mitigating climate change. Local climate networks have been recognized for their potential to govern such activities. However, less is known about how such networks are implemented and managed as well as their capacity to accelerate transformative

Exploring low-carbon procurement for public construction as a tool for decarbonizing heavy industries: An analysis of current practices in the Netherlands, Sweden and Taiwan

With the calls raised in “buy clean” within green public procurement (GPP) for construction, recently, low-carbon procurement (LCP), the subset GPP is getting more and more attention. However, not many academic publications explore LCP for public buildings or infrastructure projects. Moreover, it appears that little research further investigates its influence on the decarbonization of hard-to-abat
