Demands for novel lactic acid bacteria with potential to be used as probiotics along with healthy fermented plant-based products increase worldwide. In this study, a novel Lactiplantibacillus plantarum P31891 strain with enzymatic capacity to degrade tannins and ferment xylose was used as starter culture for fermentation of a quinoa-based beverage. The probiotic potential of the selected strain wa
Airborne wear particle emission has been investigated in a pin-on-disc tribometer equipped with particle analysis equipment. The pins are cut out fromcommercial powder metallurgy automotive brake pads as with and without copper content. The discs are cut out from a commercial grey cast iron automotive brake disc as cut out and as in addition to a laser cladded with a powder mix of Ni-self fluxing
Surface crack width is regulated in codes to limit corrosion of reinforcement bars in concrete. However, the influence of surface crack width on corrosion damages is not directly inferable from previous research.In this work, data on corroded cracked concrete specimens in chloride environments was compiled. Detailed information was included, such as crack and pit locations, local corrosion pattern
Using Steven Luke’s famous Three-Dimensional Power theory this thesis aims to explain how much political power the Iranian women had during the secular Pahlavi era compared to the Islamic Republic of today. I will outline the reasons for change of formal and informal power structures from 1942-2010.I find that Iranian political system has a complex structure with a multitude of loosely connected p
The essay examines the effects of the proportion of women in Swedish municipal councils. Both a quantitative small-n and a large-n study is conducted. The role congruity theory of prejudice and several theories on the effects of female political representation, as well as previous research, guides the study. In the small-n study, the occurrence of gendered patterns in committee seat allocations in
Gender equality is now more than ever a highly discussed topic within many different aspects of society. Also, being an entrepreneur is becoming increasingly more accessible and popular as a choice of occupation. This study aims to analyze the potential relationship between gender equality in entrepreneurship and the outcome on economic growth. By developing an index which ranks American states’ d
Syftet med studien är att undersöka sambandet mellan olika riskfaktorer och riskpremiens storlek i företagsobligationer utgivna av nordiska bolag under tidsperioden 2013-2018. För att undersöka studiens syfte används en kvantitativ metod med deduktiv ansats. Studien utgår ifrån tidigare forskning som undersökt vilka riskfaktorer som påverkar storleken av en företagsobligations riskpremie på andra
Restidskvot används som ett mått över kollektivtrafikens attraktivitet, många kommuner delar viljan att göra kollektivtrafiken just attraktivare för att öka andelen resenärer. Stockholms län visade i en rapport för över 25 år sedan ett samband mellan restidskvot och kollektivtrafikandel. Den här rapporten undersöker huruvida ett liknande förhållande existerar för medelstora kommuner och hur det sa
In this thesis, a house price evolution equation of Denmark's municipalities is proposed and solved using both an iterative optimization algorithm, and a closed form solution using Vector Autoregression. The quality of the solutions is investigated, analyzed and compared. Focus is put on the accuracy of the generated price predictions and to what degree the model parameters follow expected fea
As the drive to find sustainable and technological solutions to ongoing global problems becomes increasingly urgent, implementing timely innovation is needed now more than ever. The concept of regional innovation systems has recently gained popularity as a recipe for innovation and increasing knowledge transfer on a smaller scale. Specifically, the role of education in regional innovation systems
Uppsatsen behandlar det rättsliga läget i Sverige för användningen av AI-system vars syfte är att utföra ansiktsigenkänning. Polismyndighetens användning av tekniken står i centrum för analysen. Användningen möjliggörs av AI-förordningen som reglerar när aktörer får eller inte får använda olika typer av AI-system. I förordningen regleras bland annat situationer då en behörig myndighet som exempelvThis thesis examines the legal framework concerning AI systems for facial recognition. The main focus is on the Swedish Police Authority’s use of the technology. The AI Act is the main legal text governing AI systems and it regulates when different types of AI systems may be used. The AI Act includes regulation surrounding the use of AI systems for facial recognition by, for example, the Swedish P
The aim of this study is to investigate if a researchers presence affects participants performing a virtual reality evacuation, and if by removing the researcher, the results better resemble the results produced in a real world experiment. Initially, a study on previous research in human behaviour in fire, the effect of a researcher's presence and Virtual reality experiments was conducted. 54
Many circuits in integrated-circuit design require a time-shifted or multi-phase clock. In time-interleaved ADCs, multiple phases enable a higher effective aggregate sampling rate without increasing the individual clock rate. In contrast, in SerDes links, bit throughput increases while keeping each lane at a lower base clock. In 5G and 6G wireless equipment, multiple phases can be used to drive a
