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

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

Entreprenörskap karaktäriseras av en snabbföränderlig och osäker miljö. I tillägg har intressenter i området olika perspektiv och bekymmer samt är beroende av varandra. För att en ny affärsverksamhet ska lyckas är finansiering och humant kapital ofta viktiga faktorer, särskilt inom tech, och i dagsläget är det svårt att skapa/uppnå ”rätt” koppling i samspelet mellan unga företag (ideators), investThe field of entrepreneurship is characterized by a fast-changing and uncertain environment. In addition, stakeholders within the field all come with different perspectives and concerns and are dependent upon each other. For a new business to be successful, financing and human capital are often determinants, especially within tech, and it is difficult to attain the “right” connections between youn

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

DMSO är ett vanligt lösningsmedel för studier av syntetiska molekyler i biologiska system, bl.a. inom läkemedelsutveckling. Trots detta är lösningsmedlets interaktioner med dessa syntetiska molekyler och deras målprotein inte tillräckligt undersökta. DMSO kan påverka proteinerna struktur eller ha någon annan inverkan inbindningen. I detta arbete har denna möjliga effekt studerats för inbindningen DMSO sees common application as a solvent for studies of synthetic molecules in biological systems, in fields such as drug design. Despite this, the possibility and nature of solvent interactions with both synthetic ligand and their target macromolecules is widely unexamined. DMSO could potentially have significant effect on binding characteristics due to conformational changes of protein structur

This thesis aims to provide information regarding which critical success factors that are beneficial for small and medium enterprises when implementing Robotic Process Automation. It has been done by identifying 11 critical success factors from 14 academic research articles treating Critical Success Factor’s in Customer Relationship Management and Enterprise Resource Planner implementations. The 1

Thesis Purpose: The aim of this research project was to uncover the meaning of extraordinary experiences for consumers’ identity projects and to understand how extraordinary experiences, rather than brands and possessions, can be used for self-presentation and self-extension. Methodology: Following Van Manen’s method for hermeneutic phenomenological research combined with Derrida’s notion of deco

The main challenge to future scenario construction is to help people see themselves as part of a larger system in a way that empowers them rather than reinforces the belief they are helpless. This thesis aims to overcome this challenge by investigating what can be learned from the Japanese tradition of repair called Kintsugi and the underlying Wabi-Sabi philosophy. Subsequently, the research explo

This study examines collective action frames visible in the social media commentary of the ongoing Farmers’ protest in India. It addresses the theoretical and critical questions about social media’s role in the 21st century social movements as well as how framing contributes to mobilization and overcoming the collective action problem. Previous studies have advocated both for and against using soc

The world of work is central to development, if one defines development as economic and social progress and wellbeing of individuals, families and societies. In the last decades of globalization the International Labour Organization has struggled to retain relevance and ensure “decent work” for all. The introduction of the 2019 ILO Centenary Declaration for the Future of Work sets up new guiding p

Försörjningskedjan har stor potential till optimering. Många olika delar av kedjan kan optimeras och alla tänkbara förbättringar har inte testats än. Denna studien har sitt fokus på ruttoptimering, med det specifika målet att förstå hur maskininlärning kan användas inom ruttplanering, samt hur nyckelfaktorer som påverkar restiden för en rutt kan tas i åtanke för problemet. Tid lades på att studerThe supply chain has potential for growth. Many different parts can be optimized, and every possible improvement has not yet been tested. This study focuses on route optimization with the specific goal of figuring out how machine learning can be applied to route planning and how key factors that impact travel time for a route can be taken into account for this problem. Time was dedicated to learn
