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

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

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

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

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

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

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

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

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

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

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

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

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

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

För att generalklausulen i den svenska lagstiftningen mot skatteflykt ska kunna tillämpas krävs det att skatteförmånen som uppstår strider mot lagstiftningens syfte. Vad detta innebär är inte fullständigt klarlagt av vare sig lagstiftaren eller av Högsta förvaltningsdomstolen. Lagens syftar till att domstolen ska göra en analog tolkning och dess rättssäkerhet har därför varit omdiskuterad. Syftet For the general clause in the Swedish legislation against tax evasion to be applicable, it is required that the tax advantage that arises is contrary to the purpose of the legislation. What this means is not fully clarified by the legislature or the Supreme Administrative Court. The law aims for the court to make an analogous interpretation and its legal certainty has therefore been debated. The p

Predicting the stock market has been a longstanding topic of interest in financial research. It is regarded as a highly challenging but important task given the vital role the financial markets play in shaping the global economies. In this thesis, the goal is to predict the movement of the S&P 500 Index using machine learning methods. To this end, we apply two machine learning algorithms, rand

Malaria är en sjukdom som orsakas av encelliga parasiter. De parasiterna bärs av hon-myggor av arten Anopheles som främst befinner sig i de södra delarna av världen. Symtomen som upplevs av malariainfekterade människor liknar förkylningssymptom men även feber, illamående, frossa m.m. Infektionen sprids genom myggbett, sporozoiter sprids i blodet och hamnar i levern där de förökar sig vilket leder A molybdenum complex containing a chloroquinoline derivative has been synthesized; however, due to time restraints, neither X-ray diffraction nor testing of the drug has been accomplished. The identification of the complex relies solely on NMR results, which have also shown partial impurities. Therefore, for future improvements, it is suggested that flash chromatography is run after every step to

In the last 10 years, sustainability has been in focus and cities are being designed to prioritize sustainable alternatives. Today, narrowing the carriageway is used as an alternative to make way for sustainable alternatives in the existing street space. The purpose of this study is to investigate the consequences narrowing the lane can have on the lifespan of the road structure and what damage it

When in need to tell stories we often find ourselves using not only our words but also accompanying gestures, as well as pictures. However, what if we were to use only gestures to narrate? Would the stories we tell be clear enough to understand? The thesis investigates the potentials and limitations of pantomime, which consists mostly of gesture, for storytelling. Concretely, through a unique two-
