Flooding of urban areas is a worldwide problem as cities grow and the amount of impermeable surfaces increase generating more surface runoff. In the Zambian city of Ndola, the capital of the Copperbelt Province, flooding occurs in some parts of the city especially on Dag Hammarskjöld Drive at the underbridge, which has been flooding every rainy season consecutively for 8 years now. The main object
The production of single cell biomass by the collaboration company in this project for use as a meat alternative is a potential source of sustainable alternatives to functional ingredients for the food industry. With its high protein content, creating a protein isolate from the single cell biomass became interesting and a study of single cell protein functionalities could offer a possibility to in
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
The growing number of African Presidents on Twitter affirms that media, in all its forms, will always play a fundamental role in contemporary politics. Moreover, based on its face value, the presence of Presidents on Twitter could suggest that citizens are gaining unprecedented access to their president. But, this thesis contends that the newness of Twitter should not blind us into thinking that t
The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. The test program is for the first scoping test that will be performed o
A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes
Frågan om en kriminalisering av karteller inom den hårda kärnan har sedan millennieskiftet utretts tre gånger inom ramen för statens offentliga utred- ningar. Varje gång har detta avstyrkts. I USA har kartellsamarbeten däremot varit kriminaliserade sedan 1890. Idag tillämpas hårda straff, enskilda förtag har fått betala hundratals miljoner dollar i böter och många personer har dömts till långa fänThe issue of criminalization of hard core cartels has been considered three times in Swedish Government Official Reports since the turn of the millen- nium. The proposition was rejected every time. In the United States, collusion in restraint of trade has been criminalized since 1890. Harsh punishments are applied, some companies have been fined hundreds of millions of dollars and many individuals
An investigation into the use of statistical texture analysis in combination with ultra high-frequency ultrasound for diagnosing Hirschsprung’s disease (HD); An illness that manifests itself through the absence of ganglia cells in lower parts of the intestine. Current diagnostic techniques carry a higher risk of long-term consequences in newborns and children which enables a new avenue of research
In this thesis the WKB-approximation is used to simulate the tunneling current for an Esaki nanowire diode and the result is compared to data from Esaki nanowire diodes grown with MOVPE. The WKB-approximation with triangular potential barrier predicts a strong increase of the tunneling current as a function of the doping densities and at the highest doping levels it gives lower tunneling distances
The goal of this Master’s Thesis is to investigate the implementation of cryptographic algorithms for IoT and how these encryption systems can be integrated in a NarrowBand IoT platform. Following 3rd Generation Partnership Project (3GPP) specifications, the Evolved Packet System (EPS) Encryption Algorithms (EEA) and EPS Integrity Algorithms (EIA) have been implemented and tested. The latter are b
Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density var
This thesis creates multiple indices to score and rank developing countries with regard to their suitability for engaging in debt-for-climate swaps, and thus identify the most suitable country candidates. The origin of debt-for-climate swaps lies in the 1980s, and after a period of diminished use and attention they have become a topic of discussion again, especially in the last two years. Desp
Kubernetes is a container orchestration platform growing ever more popular, and as the software industry shifts into the container cloud, security will become paramount. The Common Vulnerabilities and Exposures (CVEs) systems cata- log and provide references to known vulnerabilities. The goal of this thesis is to systematically evaluate the security situation of Kubernetes through common mitigatio
The growth of tissues and organs in plants is governed by the morphogen auxin coupled with the membrane protein PIN, which together generate patterns that guide development. Systems of this kind have been studied extensively in experiments and computational system biology models. This thesis builds on that work by introducing a stochastic version of these models to examine differences between stoc
This degree project aims to develop standard methods for determination of the size distribution in different samples using laser diffraction, as well as to create methodologies for development of new methods for unknown samples. The size distribution is crucial to understand for pharmaceutical products since it affects properties such as the stability and bioavailability of the product. A way to
The beverage packaging industry is growing rapidly, driven by urbanization and changing lifestyles. Demand for packaged beverages with extended shelf life is driving sales of products with superior barrier properties, due to the high environmental impact of food waste compared to packaging waste. Despite progress, packaging waste represents more than a third of total waste. Thus, milk and plant-ba
The thesis explores the decision-making process of sustainable entrepreneurs for securing external funds by adopting the “triple bottom line” research perspective (Hall et al., 2010; Sarango-Lalangui, 2018). It delves into how sustainable entrepreneurs assess and exploit funding opportunities while balancing their economic and non-economic goals. The research addresses two primary questions: what
