Trichoderma are fungi that form symbiotic relationships with plant roots, representing an ecological topic for pest management. It offers a sustainable alternative to agrochemicals through biostimulation and biocontrol. However, the host plant needs to effectively manage a trade-off : using Trichoderma as a defense mechanism while not getting damaged by its cytotoxic compounds, like the antibiotic
Air traffic control (ATC) is a safety-critical activity in which practitioners must continuously navigate uncertainty, trade-offs, and operational variability. In such environments, resilience emerges not from strict adherence to procedures alone but from the adaptive strategies that air traffic controllers employ to sustain safe performance. One striking property of air traffic control is that co
Märta Måås-Fjetterström’s textile career was largely based on a collective effort. As a textile artist in her own workshop, she drew patterns that she let employed weavers weave. Together with a few other artists, she helped elevate the craft – the carpet – to the realm of art, by signing her works early on. After Märta Måås-Fjetterström’s death, Barbro Nilsson took over the role as artistic direc
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
Parasites play a fundamental role in explaining variation in population dynamics in wild ecosystems while also acting as a better model-system to study similar or related human infections. Since the late 1800s, malaria parasites have played a crucial role in vector-borne disease research. Many intrinsic and environmental factors can affect the level of infection transmission and prevalence among a
Large and old trees provide important habitat structures and support a high diversity of species. Habitat continuity and landscape connectivity is crucial for species associated with oaks. Fragmentation, agriculture intensification and changed forest management has caused a reduction of old and large oaks, which threatens the long-term persistence of oak associated species by reducing habitat cont
As the market for biopharmaceuticals grows, the demand for continuous downstream pro-cessing (DSP) increases. This thesis tackled one of the key factors in successfully creating a continuous chromatography process: the ability to have an automated supply of complex buffer solutions. It aimed to develop and evaluate a Buffer Preparation Unit using an ÄKTA Pure machine, as well as the development of
This study investigates the occurrence and distribution of 18 lichen species associated with Nordic alvar and Precambrian limestone habitats on Gotland and Öland, which represent globally unique environments with a generally high biodiversity. During field surveys in the spring of 2025, historically known sites of the chosen lichen species were revisited, where species presence, frequency, and env
Streptomycetes grow as filamentous cells called hyphae. These cells elongate using a polar method of growth where the cell wall synthesis is restricted to the hyphal tips. It has been proved that the protein DivIVA directs the cell wall assembly to the poles and initiate branch formation along the lateral cell wall. Observations of DivIVA shows that it is regulated by AfsK, a Ser/Thr protein kinas
Denna uppsats behandlar den omställning till ett hållbart livsmedelssystem som efterlyses genom EU:s gröna giv (hädanefter EUGD) och den tillhörande Från jord till bord-strategin (hädanefter F2F). En sådan omställning bör enligt EUGD uttryckligen innebära djupgående förändringar. Uppsatsen undersöker i vilken mån de djupgående förändringar som åsyftas möjliggör alternativa sätt att organisera och This thesis addresses the transition towards a sustainable food system as called for by the European Green Deal (from now on referred to as EUGD) and the accompanying Farm to Fork Strategy (from now on referred to as F2F). Such a transition should, according to the EUGD, explicitly involve profound changes. The thesis examines the extent to which the profound changes referred to make alternative w
Teknikutvecklingen, särskilt inom AI, har möjliggjort produktion av deepfakes, det vill säga artificiellt genererat eller manipulerat material som kan framstå som mycket autentiskt. Samtidigt har digitaliseringen medfört att digital bevisning fått en allt mer central roll i rättsprocesser. Detta aktualiserar nya rättsliga utmaningar, eftersom möjligheten att skapa övertygande falskt material riskeTechnological development, particularly within AI, has enabled production of so-called deepfakes, i.e., artificially generated or manipulated material that may appear highly authentic. At the same time, digitalisation has made digital evidence central in legal proceedings. This creates new legal challenges, since convincing false material may undermine the reliability of digital evidence. The pur
We review groups acting on rooted trees and discuss their topological and measure-theoretic structure as compact topological groups using the theory of profinite groups and Haar measures. We introduce new notions of fractal-like structures for groups acting on rooted trees: shifted fractality and shifted super strong fractality, as generalisations of fractality and super strong fractality. These n
Assortative mating describes reproductive patterns in which individuals pair based on their phenotypic similarity. Although this has often been explained as a result of mutual mate choice, recent reviews suggest that it may instead arise from indirect ecological mechanisms or methodological biases. Here, I studied a colony of spotless starlings (Sturnus unicolor) to analyse the relationship betwee
Speech has become an increasingly important source of non-invasive information for Parkinson's disease detection, but much existing work still relies on sustained vowels. This thesis investigates whether carefully represented continuous speech can provide added predictive value over a strong sustained-vowel benchmark. Using the NeuroVoz corpus, sustained-vowel recordings were first used to est
Past and present measurements of radionuclide activity concentrations in the seaweed species Fucus spp. on the Swedish west coast have shown significant temporal variation. The current understanding is that marine discharges originating from remote nuclear facilities contribute to the observed activity levels. Initial statistical exploration has been done, but no detailed modelling has been perfor
I detta arbete undersöks möjligheten att införa ett webbaserat alternativ till den nuvarande Qt-baserade gränssnittsdelen i kursen VSMN20, Programutveckling för tekniska tillämpningar, vid Lunds Tekniska Högskola. Bakgrunden är en tydlig rörelse på programvarumarknaden mot webbaserade och molnbaserade lösningar, och frågan om hur man skulle kunna få in den förändringen i en kurs där studenter arbeThis study evaluates three Python-based frameworks for developing web applications for finite element analysis: Dash, Streamlit, and NiceGUI. The evaluation focused on interactivity, usability, and suitability for inclusion in a course at LTH about software development for technical applications. To compare the frameworks, the final course project was recreated in each of them while keeping the un
Rebecca Yarros’s Fourth Wing (2023) is a romantasy novel with a complex dragon society where dragons’ personalities, tempers and looks vary and affect each other. It is a new work of fiction, the first book in her still unfinished Empyrean series, and thus not many have had the chance to explore and discuss it in a formal capacity. The previous discussion is mainly made up of book reviews, and the
Förtätning av städer med en hög andel hårdgjorda ytor i kombination med klimatförändringarna gör urbana miljöer särskilt sårbara. Hållbar dagvattenhantering kan bidra till att öka klimatresiliensen i städerna, samtidigt som de genererar flera mervärden. Vilket gör de särskilt lämpliga i städerna där tillgången till mark är en begränsad resurs. Syftet med detta examensarbete är att tillvarata på in
Det svenska ränteavdraget är en omdiskuterad skattepolitisk åtgärd som ofta anses bidra till både hög skuldsättning och driva upp bostadspriser, samtidigt som det underlättar för hushåll med svag ekonomi genom minskande boendekostnader. Det finns osäkerheter kring vilka ekonomiska konsekvenser som sker vid avskaffande, särskilt på lokal nivå. Ränteavdraget är ett avdrag som minskar den skatt du b
