Achieving pure protein with high enzymatic activity for research and practical teaching purposes is essential. In this study the protein BoGal36A was purified using cells or lysate obtained from three different expression methods. The expression was performed using bioreactor, shaking flasks and a prepared lysate of cells grown in shaking flasks at Lund protein Production Platform (LP3; (kindly pr

Endotherms are restricted in their activity by the amount of heat they can lose, as hyperthermia can be lethal. As we are expecting increasing ambient temperatures on earth it is crucial to investigate how different species are affected by heat. 28 male captive-bred zebra finches were forced to exercise in a hop-flutter wheel in different ambient temperatures (10, 20, 30 and 35 °C). Body temperatu

Signal integration and cues weighting during orientation in insects is an open scientific question. This study focuses on understanding how dung beetles weigh sun cues of different light intensities. Alongside this, my study also tries to investigate potential behavioral effects of AprilTags application, which has great potential in future studies in this field, on beetles’ orientation. The South

Region Skåne bedriver ambulansverksamhet med den privata aktören PreMedic och den offentliga motsvarigheten Medicinsk service. Denna uppsats undersöker om det finns skillnader i prestation mellan PreMedic och Medicinsk service när det gäller Region Skånes två uppsatta mål för ambulansverksamheten. Skillnader i hur väl Region Skånes mål för ambulanssjukvården uppfylls har välfärdsimplikationer, eft

Tänk på en ödla som behöver gömma sig från en fågel, annars blir den uppäten. Det skulle vara klokt för ödlan att ha en färg som gör att den inte syns så bra i landskapet. Tyvärr är naturliga landskap sällan enhetliga — bakgrunden ser olika ut på olika platser. Ödlan måste alltså bestämma sig om den ska ha en färg som är specialiserad för en viss typ av bakgrund, eller en färg som ger ett hyfsat bIn a changing heterogeneous landscape camouflage becomes a less effective defence for a mobile prey item because the prey needs to move across backgrounds where it is more visible to the predator. Often, some subhabitats host more resources than others, adding an additional complexity. The prey can thus either try to generally match many subhabitats or specialize to one habitat type, often resulti

Social sustainability has increasingly become a central objective in Swedish urban planning. However, previous research highlights that its vague definition has led to diverse interpretations of its meaning and thus varying efforts in planning. This study examines how “Fokus Skärholmen” has implemented social sustainability in its detailed planning, focusing on physical measures linked to the conc

Cloudbursts and flooding that results from such intense rainfall constitute a growing risk as climate change intensifies precipitation patterns. This is a growing issue that municipalities can no longer ignore; they must actively address it. The issue of cloudbursts is highly relevant given the future climate risks we face, and it is important that Swedish cities are prepared. In this context, the

Title: TAKT Production System for Assembly (including material supply) of Crushing Equipment at Sandvik Problem formulation: A major part of Sandvik’s production system is driven by forecasting. While this method provides a structured approach for anticipating future demand, it introduces several operational challenges that disrupt the capacity of the equipment assembly line and flexibility. Thes

This study investigates how strategic communication can be utilized to reduce the risk behavior of railway track trespassing (“spårspring”) in Sweden, by conducting a qualitative content analysis of three selected risk communication campaigns: Klara, färdiga (Sweden), Sett grenser - Sei ifra! (Norway), and THINK! (UK). The research focuses on investigating the communicative strategies and thematic

This thesis critically examines the Swedish ‘Security Zones’ legislation, the associated governmental discourse on organised criminality, and their implications for equality and racial justice. Through a critical discourse analysis, the thesis illustrates how the extended discretion afforded through the legislation facilitates law enforcement’s capacity for racial profiling and discrimination. It

Problem Statement: Sandvik Rock Processing is in the need for a classification tool, which can help them improve their inventory management. Currently, there are problems with inefficiencies with deficit as well as excess in inventory. The new classification shall the basis for the differentiation of service levels and facilitate a shared view on items’ importance. Purpose: The purpose of this th

The thesis explores the agency of material artefacts in shaping co-presence and facilitating social interaction in three central squares in Malmö, Sweden: Stortorget, Lilla Torg, and Gustav Adolfs Torg. Drawing on a relational approach to space and Actor-Network Theory, the study combines structured and unstructured observations to analyse patterns of mobility, activity, and interaction. Findings

Dwarf galaxies are perfect candidates for studying dark matter due to their abundance in our Universe, low baryonic content and diverse appearance. They are considered as one of the most important probes of cosmological models, such as the most accepted ΛCDM, and are particularly important in the context of evolution of galactic environments. Satellite galaxies and their remnants can give us furth

The COVID-19 pandemic has impacted the global economy, and I want to know whether China, as one of the world’s major economies, has chosen to sacrifice environmental resources for economic development during the post-pandemic era. By combining social factors and natural environmental factors, I established a model of the air quality changing trends among China’s major cities. According to comparis

The rule of law is a cornerstone of modern constitutional democracies, not merely as a safeguard against tyranny and arbitrariness, but as a principle inherently connected to human rights, legal certainty, and democratic accountability. Within the European Union, recent years have witnessed growing tensions between the expansion of regulatory frameworks and the preservation of individual guarantee

This thesis explores how urban design can help commuter towns like Rimbo shift from passive “sleeping cities” into resilient, livable, and locally grounded communities. Using Rimbo as a case study, the project responds to its growing regional role and strong local identity by proposing a new mobility hub and five design strategies. These aim to strengthen connections, activate the town center, and

Denna uppsatsen undersöker hur den ukrainska fintech-aktören Monobank har använt strategisk kommunikation på Instagram för att mobilisera resurser och stöd för nationella intressen under Rysslands invasion av Ukraina. Genom en kvalitativ innehållsanalys av bankens inlägg på Instagram, kompletterad med semistrukturerad intervju, analyserar studien hur retorik, storytelling, mobilisering och affektiThis thesis investigates how the Ukrainian fintech actor Monobank has employed strategic communication on Instagram to mobilize resources and support for national interests during Russia’s invasion of Ukraine. Through a qualitative content analysis of the bank’s Instagram posts, supplemented by semi-structured interview, the study examines how rhetorics, storytelling, mobilization, and affective b

This thesis investigates how the effectiveness of monetary policy varies across high- and low-inflation regimes by examining high-frequency monetary policy shocks in the eurozone, Sweden, and the United Kingdom from August 2004 to August 2024. Using local projection with regime-dependent specifications, it assesses the varying impact of contractionary shocks in low- and high-inflation environments

Följande studie undersöker sambandet mellan självrapporterad ensamhet och användning av artificiell intelligens (AI), med en uppdelning mellan social (t.ex. chattbotar) och produktiv (t.ex. akademiska verktyg) användning, utifrån kön och ålder. Totalt besvarade 92 deltagare UCLA Loneliness Scale samt två egenutvecklade skalor för AI-användning. Resultaten visar att ensamhet signifikant predicerar This study investigates the relationship between self-reported loneliness and AI usage, distinguishing between social (e.g., chatbots) and productive (e.g., academic tools) usage across gender and age. In total, 92 participants completed the UCLA Loneliness Scale and two custom AI usage scales. Findings reveal that loneliness significantly predicts greater use of social AI, but not productive usag
