This thesis provides a brief introduction of the concepts “Post-normal Science (PNS)”, “Extended Peer Community (EPC)” and “Environmental Decision Making (EDM)”. PNS is applicable when uncertainties in the interface between science and decision making are too great for traditional science and EPC is a method which is an important part of PNS. EDM is a system that tries to assist the decision maker
A Credit Default Swap spread is a reliable measure of credit risk as it is the compensation demanded by a party to bear this risk. Officially, credit risk is denoted as credit ratings announced by credit rating agencies. Since rating announcements contain information regarding credit risk, the market should incorporate this new information into the CDS spread. The aim of this study is to investiga
The aim of this study has been to investigate the technical, economical and psychological barriers for the market introduction of battery electric vehicles (BEV) in Sweden. The current situation as well as future possibilities for battery electric vehicles in Sweden has also been central to this study. The study is of a qualitative nature, and is largely based on interviews with experts from the b
Syftet med rapporten är att utvärdera hur säkerheten vid schaktarbeten kan förbättras och vilka hjälpmedel som finns för att skapa bättre förutsättningar samt bedöma påverkan ett sådant hjälpmedel skulle ha på framdriften. Genom litteraturstudier belysa risker med schaktningsarbetet och hur planeringen går till för att skapa rätt förutsättningar. Genom dokumentstudier, observationer och intervjue
The fermented tea beverage kombucha is a traditional drink that has been consumed for thousands of years in Asia. Over the past decades, it has gained greatly in popularity amongst consumers and researchers also in the rest of the world. Kombucha is produced through fermentation of sweetened tea by a complex community of bacteria, mainly dominated by acetic acid bacteria, and a variety of yeast. D
Freevalve AB develops camless valvetrains for internal combustion engines using pneumatic and hydraulic systems. An air compressor is used to generate pressure in the pneumatic system. To further increase efficiency of the Freevalve system, a new compressor tailored to its purpose, is being developed in house. This thesis is part of the development of this compressor, which is a reciprocating pis
As technology advances and population rises, requirements for everyday doors change. In the industrial sector, companies have to keep up with the increase in supply and demand. A well-functioning industrial folding door contributes to a steady flow of goods. Folding doors come in many different sizes and are often installed in narrow spaces. In order for any door supplier to stay competitive, offe
Introduction: In this work, oil from Baobab seeds was extracted and analysed in order to determine how much oil the seeds contain and the fatty acid composition of the seeds. Background: A lot of seeds go to waste when either producing drinks of Baobab fruit or simply eating the fruit raw. Thus, it would be favourable if it was possible to produce a product based on the left-over seeds, suitably
This study focuses on the relationship between education and economic growth, specifically the effect a potential decline in schooling caused by the ongoing Covid-19 pandemic would have on the economic growth of a country. Using an inductive approach, the study focuses on the Sub- Saharan African countries, especially Kenya, since there is anecdotal evidence that a significant number of students h
Only recently has a geographical viewpoint on sustainability transitions opened up the containerized view on transition trajectories. Next to the important step of institutionalising niche logics transforming them into regime rationalities, the multi-scalar perspective reveals that niches, as well as regimes, can also upscale. This means that the socio-technical configuration of the niche or r
A large share of the existing building stock in Sweden originates from the so-called Million Building Programme, a large-scale construction wave between 1965 and 1974 to tackle the housing shortage at this time. Those buildings have very high energy demand and require renovation due to age and often neglected maintenance. The Swedish government’s long-term climate and energy goals are tied to an e
Tropical forests are of great importance to all living-beings due to their high biodiversity and the valu-able resources, such as food and fuel, they provide. In addition, tropical trees sequester a high amount of carbon and consequently over half of the global forest carbon stock can be found in the tropics. Climate change, however, might weaken this carbon sink and possibly result in tropical fo
Research conducted on industrial symbiosis often brings up the importance of trust and collaboration related constraints and enablers if inter-organizational efforts are to be pursued. This is also found in literature related specifically to Sweden and its agri-food sector. There are limited examples of collecting empirical evidence on trust in relation to IS and even less so with a focus on SMEs.
The increasing amount of renewable energy in the electrical grid comes with several challenges, of which overvoltage and congestion (overcurrents) are the subjects of this work. One flexible way of handling these problems is active management by some control system. There is a trade-off between simplicity when implementing the control system and the performance. In the project Active Network Manag
The outbreak of the Covid-19 pandemic triggered changed circumstances extensively. One aspect of such changes arise from issues in cross-border supply contracts, for example due to incapability of contractual performance because of entry bans and lack of labor force as the employees were set on quarantines. Usually contractual non-performance leads to breacher’s liability for damages, but exceptio
This thesis analyses the material culture of karate clothing in Sweden, namely the karate belt(obi) and the karate uniform (gi). It employs ethnographic methods to observe how these objects reveal themselves in observation and interview in the karate practise hall (dojo), and uses a Bourdieuan framework to analyse the different types of capital which emerge; cultural, social and symbolic. This stu
The purpose of this study is to test the sustainable development of Costa Rica between 1890 and 2015 based on Genuine Savings. The Genuine Savings estimations are composed of indicators on fixed capital, natural capital, and human capital. Indicators for this study were built with data from several sources including local and international projects, as well as governmental data. The data was then
