Catalytically active wire meshes were used to combust different pollutants present in flue gases from bio-fuel combustion, e.g. CO, propylene, terpenes and tar. Alumina was spray-deposited onto wire meshes of Kanthal AF (8-20 Tayler mesh) with a plasma spray equipment. The specific surface area of the ceramic layer was increased through wash coating, in-situ precipitation or sol-treatment. The cat
Dark-grown tigrina-d(12) mutants of barley (Hordeum vulgare L.) accumulate abnormally high amounts of the chlorophyll intermediate protochlorophyllide. In light dark cycles this leads to necrotic segments of the seedling leaves and lethality due to photodynamic damage by the excessive protochlorophyllide accumulated in the dark period. Upon inhibition of the early chlorophyll biosynthetic enzyme,
In 2000, the Clinton Administration in the U.S. adopted the Commodity Futures Modernization Act, which deregulated the U.S. trade with financial instruments on commodity markets. With respect to this adoption, it has been regarded as one catalyst for the Global food crisis 2008, where millions of individuals lacked provision and access to agricultural products and nutrition. From the perspective o
Hittills har över 50 miljoner ton e-avfall genererats globalt (World Economic Forum, 2019), vilket väcker frågan om den cirkulära ekonomins roll i kampen mot klimatförändringarna (Ellen MacArthur Foundation, 2021). I detta examensarbete undersöks möjligheterna för Axis Communications att införa ett system i USA för att ta tillbaka produkter som tagits ur bruk och återvinna dem. Inom detta område So far, over 50 million tonnes of e-waste have been generated globally (World Economic Forum, 2019), raising the question of the role of circular economy in combating climate change (Ellen MacArthur Foundation, 2021). This thesis explores the opportunities for Axis Communications to introduce a take back system for recycling decommissioned products in the US. Within this scope, several areas are
This thesis explores the socially constructed phenomenon that has arisen as a result of the proliferation of social network sites that has penetrated our daily lives. The qualitative study analysed how university students experienced the global outage of Facebook, Instagram and, WhatsApp on October 4th, 2021, because of the Meta-owned ecosystem of social media. Moreover, the study examined how 2 g
This paper addresses the problem of urban transport management in Sofia ? the capital city of Bulgaria. It highlights the tensions and contradictions in the current policy and practice and suggests that the adoption of mobility management in policy making would elevate municipal capacity to deal with complex transport-environment conflicts and set the framework for a sustainable development of the
Based on a new Swedish legislation for accident prevention and protection the support of the establishment of municipality accident prevention programs with documented basic data sets for decision-making is discussed. A division into four documents of basic data sets is proposed. A process is projected for the production, decree and compliment of municipal accident prevention programmes and the do
Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the produc
Type 2 diabetes mellitus (T2DM) in children and adolescents is increasing in the world and the United States of America (US). Previous research has shown that the nurse has an important role in the management of T2DM in children and adolescents but few studies has covered how the nurses perceive and experience this role. This paper aimed to describe how nurses in the US experience their role and t
Olympic legacy was previously seen as a potential burden on the host city, however an evolutionary shift has occurred whereby it can now be regarded as an instrument in wider urban policy planning. Sustainable development is a requirement set by some governments, and London 2012 aimed to use the Olympic legacy for sustainable development in the form of urban regeneration. This paper is a case stud
Popular Abstract in Swedish Bröstcancer är kvinnans vanligaste cancerform och globalt sett den cancer som leder till flest dödsfall. Bröstcancerscreening med mammografi används därför i syfte att hitta cancern tidigt. En tidigt upptäckt cancer har oftast en bättre prognos med möjlighet att minska dödligheten i bröstcancer. Mammografitekniken är dock behäftad med vissa begränsningar vad gäller känsAbstract: Mammography is currently the established method in breast cancer screening, although the sensitivity is known be affected by overlapping tissue concealing tumours. Breast tomosynthesis takes advantage of multiple exposures at different angles reducing the negative effect of obscuring tissue. The aim of this thesis was to investigate the use of tomosynthesis in breast imaging with a spec
Net primary production (NPP) is the difference in gross photosynthetic assimilation of carbon and carbon loss due to autotrophic respiration, and is an important ecosystem variable that facilitates understanding of climate change impacts on terrestrial ecosystem productivity and ecosystem services. The aim of this study is to rapidly estimate the NPP of European potential natural vegetation for cu
Background: Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by tau and amyloid brain pathology. With the gradual degeneration of neurons, cognitive symptoms will arise and the affected individual will eventually develop AD dementia. The neuropathologic hallmarks of AD have been observed also in cognitively healthy individuals, which has led to the assumption that the disorde
Semantic Web technology has attracted much interest for its ability to integrate and deliver information from different sources, and increasingly, geodata are being published as triple data according to the graph structure laid out in the Resource Description Framework (RDF). Although the Semantic Web already contains a large volume of geotagged information, there is still a lack of suitable geome
Seeing how climate change disproportionately affects women and children, the voices of young people and women are vital to incorporate into discussions and decision-making processes regarding climate change. This thesis explores the experiences of young women in the climate movement who have participated at the COP climate conferences between 2015-2023. By drawing on the theoretical framework of f
