The aggregation of proteins into amyloid fibrils via erroneous folding, also known as misfolding, occurs in several diseases. As a consequence, the study of the kinetics and thermodynamics of this process is currently intensely pursued. Here, we study a minimalistic lattice-based model for amyloid formation using Monte Carlo techniques to sample the grand canonical ensemble, where the chemical pot
The relationship between business cycles and mortality has been a highly debated subject in the field of economics. The majority of previous studies, using the unemployment rate as the main proxy for macroeconomic conditions, have found ambiguous effects largely depending on how the effect is estimated. This thesis follows the methodology used by Ruhm (2000), but instead applies aggregate data for
The field of child welfare could be considered one of the most complex social systems to work within. Whether punishing for errors or satisficing calls for accountability with firing employees and pointing to individuals as the root causes of bad outcomes, the current practice in child welfare is to utilize backward looking accountability. It is argued here that child welfare agencies would benefi
The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa
With this thesis we want to prove that by using a single formula for picking stocks, Joel Greenblatt’s ‘’Magic Formula’’, it is possible to achieve returns higher than those achieved by a related index. To prove this, we will construct a portfolio, according to “The Magic Formula”, and backtest the portfolio in the Swedish stock market. The test period will be March 1999 to January 2010 and we wil
Oil has been for the past 50 years the most widely used energy source. That is because oil contains a lot of energy and is easy to transport and store. But the use of oil has drawbacks; it is believed to change the earth’s climate due to the combustion and the emissions of the green house gases. The particles from the combustion cause problems for the human health. Today Oil accounts for 33 % of t
As part of a research grant aimed at producing chicken feed from the novel microalgae Scenedesmus sp., called the ReMAPP project, this thesis investigates opportunities to increase the conservation potential and protein digestibility utilizing solid-state lactic acid fermentation and commercial enzyme additives. The lactic acid fermentation mimics the traditional agricultural ensiling process, whe
Purpose: Environmental sustainability in the wine industry has become increasingly important. Most countries have implemented programs to ensure sustainability. In South Africa, the majority of wine farms belong to the sustainability scheme. However, small and medium wine farms face challenges in adopting sustainability practices. Therefore, this research investigates the barriers faced by SME win
This thesis investigates the remanufacturing potential of the electric front cross differential (eFXD) within the context of the circular economy (CE) and the R‑framework. Environmental assessment, mechanical validation and structured component classification are combined to identify opportunities and limitations for remanufacturing. The results show that a limited number of components, the tube h
The essay deals with implications for Human Rights development in light of China's rise to power. It discusses the problem from three perspectives, China's Human Rights commitment, the clash between western and Asian values and China's potential influence. It is mainly an overview and discussion of the problems and complexities involved in the development. From these three perspective
In this thesis, we evaluate the side-channel security of the NIST HQC post-quantum cryptosystem by analysing the official FPGA decapsulation implementation. A hardware wrapper was created to interact with the HQC decapsulation modules, enabling ciphertext decapsulation with precise power trace capturing using a ChipWhisperer CW305 and Husky setup. A dataset with 20k power traces was generated from
As plastic pollution in aquatic environments persists, gaining a deeper understanding of nanoparticles has become increasingly important. Yet, the question remains: what happens to plastic as it breaks down into smaller components, and ultimately, what end products are formed? Current plastic degradation methods are limited in their environmental applicability and efficiency. This study aims to pr
Across Europe, breeding bird species are decreasing in several types of habitats. Deciduous forest specialist birds are facing a loss of habitat due to the forest management that removes important key components in the forest, e.g. dead wood. Already in Sweden three woodpecker species that are deciduous forest specialist have decreased in population: one has become locally extinct (middle spotted
This thesis seeks to answer the question of whether obligations to primary pandemic prevention and bio-risk management can be derived from the human right to health. The definition of the right to health in Article 12 of the International Covenant on Economic, Social, and Cultural Rights (ICESCR) was selected, as it is the broadest definition of the right to health in international human rights la
This thesis offers an overview of the relatively new family of Rosenbrock-Krylov numerical methods for ODEs. These methods are a further development of Rosenbrock methods, using a lower-dimension approximation of the Jacobian. The thesis gives the mathematical background to Rosenbrock-Krylov methods by first presenting Runge-Kutta methods and Rosenbrock methods, followed by the concept of Krylov s
There is a growing demand from policy makers for businesses to help close the consumer intention-action gap for sustainable product choice and strengthen the green economy. Moreover, there is increased interest from consumers in brands that are transparent about their environmental impact. This is not least the case for the focus sector of this study, food products, an industry responsible for aro
Background: The case company is a Swedish family-owned business, operating in the agri-food industry. Their philosophy is to develop, produce, and sell frozen products from the vegetable kingdom with a focus to be organic and convenient. The company has realized that the production layout and the material flow cause a lot of waste and have great potential for improvements regarding efficiency in p
Transports, and transport infrastructures enable and deliver vital societal functions in today’s society. At the same time, as sustainability becomes more and more important these sectors fail to enable the rate of change that international and national policies calls for. The electrification of the transport sector is a key driver of the future’s sustainable transport system, and the number of el
The purpose of this study is to investigate if and to what extent environmental sustainability is a contributing factor in the purchase decision of craft beer among young adults. In addition, the study aims to understand how different purchasing factors are related to each other in the craft beer purchase decision. The purpose is to gain a greater understanding for the industry of small scale prod
