Axisymmetric capillary water waves on cylindrical fluid jets

Inom fysiken och vissa delar av matematiken siktar man på att beskriva så mycket av naturen som möjligt. Det gör man genom att hitta modeller som passar bäst till varje situation. Naturligtvis är vissa system mycket svårare än andra att förstå matematiskt och vattenvågor är ett exempel på ett sådant system. Under 1800-talet formulerades Euler-ekvationerna, som beskriver rörelsen av ideala fluider,In their paper, Vanden-Broeck, Miloh and Spivack (Wave Motion 27, 1998) describe two limiting behaviours of irrotational, axisymmetric capillary water waves using numerical methods. They found a two-parameter family of nontrivial solutions. Some solutions of small amplitude approach a uniform stream, while others approach a static configuration. Our main interest is with the branch of static confi

Det absoluta gehörets betydelse i gehörsundervisning – En intervjustudie utifrån både elevers och lärares perspektiv på gymnasieskolan och musikhögskolan

Denna studie fokuserar på gehörs- och musiklära-undervisning på gymnasienivå och högskolenivå där fenomenet absolut gehör är i fokus. Studien är gjord utifrån två gruppers perspektiv: elever med absolut gehör, och lärare med erfarenhet av att under visa av elever med absolut gehör. Studien belyser framför allt hur lärare anpassar undervisningen till elever med absolut gehör samt vad elever med absThis study focuses on ear training at secondary and university level where the phenomenon of absolute pitch is in focus. The study is partly from the perspective of two groups: students with absolute pitch, and teachers with experience teaching students with absolute pitch. Above all, the study highlights how teachers adapt their teaching to students with absolute pitch and what students with abso

Turning Audiences into Activists: A Qualitative Case Study of PragerU and Moral Foundations Theory

YouTube plays a significant role in the right wing media ecosystem, especially as an alternative source for news and information beyond traditional media outlets. PragerU is a far right YouTube channel with over 3 million subscribers and 1.7 billion views at the time of writing, which lies on the periphery of the Alternative Influence Network and subsequent alt-right pipeline. Using the organizati

Overcoming environmental limitations of recombinant enzyme production : An approach towards enzyme manufacturing on sustainable feedstocks

Enzymes are often considered a green approach next to conventional fossil-based chemicals helping us on the margin towards a low-impact society. While enzyme catalysed reactions are low environmental impact technologies, their production is not. In this study, a comparative life cycle assessment of different recombinant enzyme manufacturing strategies quantifies and evaluates the contribution of d

Developing an Automated System for Yeast Culture Cultivation and Control using Flow Cytometry

Flow cytometry is a versatile tool for monitoring a microbial population at a single-cell level. Multiple parameters can be monitored based on the users’ requirements through the utilization of different dyes, biosensors etc., and the use of FCM for on-line measurements during fed-batch cultivations has the potential to be used for precise process control. This project consisted of the development

Assessing the Transformative Potential of a Sociocracy-Informed Climate Change Adaptation Lab in Lund, Sweden

Effective climate change adaptation necessitates enhanced public participation as there is a need for the voice of people to be meaningfully incorporated to facilitate transformational adaptation, contend with complexity, and avoid maladaptation. Despite this, widespread participation in climate change adaptation governance in Global North countries like Sweden is currently restricted by rigid pow

Om att höra ekon från modets värld -- och om att svara själv : konstruktionen av den ideala medelklasskvinnan mellan hemideologi och konsumtion i det sena 1800-talets Sverige

The aim of this thesis is to study how the ideal middle-class femininity was constructed through fashion in late 19th century Sweden. Fashion have often been studied through the construction of gender, but this study aspires to show how fashion history also can be enriched when combined with closely related fields such as history of the body and of women’s morality. The theoretical framework is co

Predicting Protein Stability with Machine Learning

Protein stability is a property of high importance and is of interest in a variety of fields. It determines if a protein has its native fold and can be of influence in certain diseases such as Parkinson's and Alzheimer's disease. It can also be of interest in an industrial setting to optimise the stability of enzymes in certain physicochemical environments. Recent developments in machine l

The Effects of Clear-Cutting a Hemiboreal Forest on Local CO2 Fluxes in Norunda, Sweden

As CO2 builds up in the atmosphere causing global climate change (IPCC, 2022) trees have become an international symbol of combatting this, and for good reason. Trees take up CO2 which as a result combats these changes, and when these trees are cut down fewer individuals remain to take up the CO2 that we humans emit (Chapin et al., 2011). This means that clear-cut areas don’t act as the carbon sin

A Policy Analysis on Command Agriculture: An Attempt to Revamp Agricultural Production in Zimbabwe

Once the breadbasket of Southern Africa, Zimbabwe has undergone a radical transformation. Agriculture provides employment and income for the majority of the population in Zimbabwe. After the Fast Track Land Reform and its negative effects on the agricultural sector the government of Zimbabwe has employed a significant number of strategies to modernize its agriculture sector and again become the br

Navigating Family Reunification for Third Country Nationals: An Analyse of the Impact of Waiting Period Requirements on the Right to Family Life under ECHR and EU Law

The present thesis explores the requirement of the waiting period to grant family reunification to Third Country Nationals from the perspective of human rights law. It examines how this requirement, which currently forms a significant part of immigration policies within European member states, may impact TCNs' Right to family life under the European Convention on Human Rights (ECHR) and EU

In order to acquire new languages, we need to be exposed to large amounts of target language (TL) input. However, studying French as a foreign language in Sweden includes few opportunities to encounter the language outside the classroom. This means that the teacher plays a decisive role as an input provider in the French L2 teaching setting. Moreover, the Swedish syllabus for modern languages, inc

Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration

Det är möjligt att tillverka plast från socker med hjälp av bakterier, och även om detta bara görs på en relativt liten skala idag så kommer tillverkningen av biobaserad plast troligtvis öka väsentligt de kommande decennierna. Denna typen av plast tillverkas på förnybara råvaror, och är därför ett bra alternativ till plast som är baserad på fossila råvaror, som petroleum. För att öka hållbarheten Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. 3 ultrafiltration-membranes, RC70PP, GR70PP and ETNA10PP from Alfa Laval Corporate AB, were evaluated at varying cross-flow

"Europe is Breaking Them" - An Analysis of European NGOs' Narrative on the Mental Health of Migrants on the Greek Islands from 2015 until 2023

This research is framed by the tension between human security and border security which pervades the debate on migration and asylum policies in the European Union. The perspective of three prominent NGOs in this discussion is studied in the present thesis. Its particular object of research are the migration camps on the Greek islands which were established following a series of EU decisions. The p

Not All Heros Wear Capes

Purpose: The main purpose of this study is to enhance our understanding of branding communication with mass audiences using ordinary people in myth treatment. Methodology: This qualitative study explores the phenomenon of ordinary people portrayed as heroes in advertisements in an abductive manner. The research has been designed as a case study and the method for coding and analysing has been qua

Grundläggning med slitsmursteknik - Litteraturstudie

En slitsmur är en geokonstruktion som utförs genom att paneler platsgjuts med marken som form. Panelerna bildar tillsammans en samverkande vägg. Tekniken är vanlig utomlands men fortfarande relativt ovanlig i Sverige. Behovet, och därmed intresset, av slitsmurar i Sverige växer dock i takt med förtätningen av städer och infrastrukturprojekt som kräver djup schaktning och anläggning. Kraven på låg A diaphragm wall is a retaining wall which is produced as a cast in-situ concrete wall. The ground itself acts as formwork. The technique is widely used internationally but it is comparably still a rare technique in Sweden. However, the need, and therefore interest in Sweden for diaphragm walls is growing as the number of inner city infrastructure projects requiring deep excavations increases. The

Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. OSS systems cannot track the patients surfa

Quantitative susceptibility mapping of the knee: A comparison of approaches for addressing fatty tissue

Artros är en vanlig sjukdom som påverkar ett antal olika leder i kroppen. Den vanligaste av dessa är knäartros, som utgör omkring 85 % av alla atrosfall. Sjukdomen påverkar alla delar av leden, speciellt tydlig är effekten på ledbrosket som förtunnas och till slut bryts ner helt. Denna process kan leda till stora besvär, så som smärta och minskad rörlighet, men i nuläget finns mycket få behandlingBackground/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. For example, QSM of the articular cartilage of the knee has been suggested as a means to study the degeneration of this ti
