Sustainable development requires collaboration between governments, businesses, and citizens. However, economic models, sustainability practices, and global policies are currently not fit-for-purpose to maintain global temperatures to 1.5 degrees centigrade within the timescales required to maintain a safe space for humanity to thrive. This study maps the alignment of business values and practices
In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. The Swedish Research Council is supporting a project called Solar Food: Reducing Post-Harvest Losses Through Improved Solar Drying, which aims to create a low-cost solar
The objective of this thesis is to develop a methodology for evaluating the performance of material models during biaxial loads. This is done by executing identical punch tests, one in a simulation and one in a physical experiment, and then comparing the results from the two. The material model that is to be evaluated is used in the simulation and a specimen of the corresponding material in the ph
In recent years, battery energy storage systems (BESS) have gained prominence as a key technology enabling much needed electricity grid flexibility while simultaneously providing distinct value to its end-users. With the anticipated increase of residual value holding used batteries from mobility applications entering the market, more and more companies are looking to construct BESS offers around t
Food security and environmental sustainability are increasingly threatened by the current degradative practices of the agri-food industry. To mitigate the adverse environmental impacts of the agri-food supply chain, the circular food economy has been proposed as a strategy to enhance biodiversity, improve access to nutritious foods and reduce the industry’s greenhouse gas emissions. However, progr
This thesis will be an investigation into different proofs of Completeness in first-order logic. Particular attention will be put on analyzing the role of the Ultrafilter Lemma and its necessity in proving the Completeness Theorem. An attempt will be made to develop a proof that separates out this non-constructive aspect, but still uses the law of excluded middle. The overall aim is to understand
Algae blooms, induced by eutrophication, have been an increasingly prevalent environmental concern in the Baltic Sea since the 1970s, causing ecosystem degradation and hypoxia in bottom layers. One predominant harmful algae bloom-forming species in the Baltic Sea is the cyanobacteria Nodularia spumigena. N. spumigena produces hepatotoxin nodularin and is a diazotrophic alga; hence, it should be
In this paper regularization of the correlation matrix between futures contracts is examined. With starting point in the recently established HPCA framework (Avellaneda, 2019), a couple of different extensions to the one-factor model is suggested. Extensions are made in terms of adjusting the model according to different cluster structures. The data consists of futures contracts on a wide variety
Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurobehavioral problems among both children and adults. Around 5% of the children and 3- 4% of the adults suffers from the condition in Sweden. In general, diagnosed children achieve poorer results on standardized tests, receive lower grades and are more prone to dropout of school. Adults tend to struggle with work-performa
China’s economic development has not only led to enormous growth figures, but also to a severe degradation of the environment. Mass-consumption of fossil fuels like oil and coal in China contributed to reaching the level of the largest greenhouse gas emitter worldwide. For the Chinese government to react, it is crucial to take the electricity purchase decisions of households into account to succes
Supramolecular chemistry is a field in which noncovalent interactions between molecules are utilised to promote the formation of larger molecular assemblies. A single monomer consisting of a bicyclo[3.3.1]nonane backbone equipped with hydrogen bonding motifs and solubilising groups is synthesised. Utilisation of different hydrogen bonding motifs and appropriate solvent renders self-aggregation of
In Sweden, what we eat accounts for about a third of the consumption-based greenhouse gas emissions, and there is strong evidence that the most effective way to reduce emissions is to switch to a more plant-based diet. A shift is currently underway in the Swedish food system; the market for plant-based products is showing an exponential growth, coupled with, for the first time since the 1950s, a d
This thesis aims to evaluate the situation for cyclists in Stellenbosch, one of the leading cities in South Africa when it comes to planning for cyclists. The current situation for cyclists in Stellenbosch will be evaluated in terms of level of service, accessibility and safety. Moreover, the purpose of this study is also to investigate if there are there any official policies or plans to improve

BACKGROUND: Immunohistochemical staining for tumor-associated proteins is widely used for the identification of novel prognostic markers. Recently, a tissue-conserving, high-throughput technique, tissue microarray, has been introduced. This technique uses 0.6-mm tissue core biopsy specimens, 500 to 1000 of which are brought into a new paraffin array block, which can be sectioned up to 100 times. M
Thiol (SH) groups play a remarkable role in the cell with their redox state affecting the activity and structure of many enzymes, receptors and transcription factors. In the present work, carbon paste electrodes modified with sulfhydryl oxidase (SOX) were prepared. The proposed biosensor was based on the monitoring of the produced peroxide concentration that correlates with the concentration of re
Limitations of the pulse-shape discrimination (PSD) technique - a promising method to identify the charged particles stopped in planar Si-detectors - have been investigated. The particle resolution turned out to be basically determined by resistivity fluctuations in the bulk silicon which cause the charge-collection time to depend on the point of impact. Detector maps showing these fluctuations ha
