Fisken harr, Thymallus thymallus, fanns för i Lagan i södra Halland men försvann någon gång kring 1950-talet. Mänsklig påverkan i form av utbyggnaden av vattenkraften och dålig vattenkva- litet tros ligga bakom detta försvinnande. I projektet ”Sagan om harrens återkomst” försöker Sve- riges sportfiske- och fiskevårdsförbund att återfå harr i Lagan genom utsättningar i biflödet Kro- kån. Om man skGrayling, Thymallus thymallus, became locally extinct in Lagan around the 1950s due to human activity. Now, 70 years later, The Swedish Anglers Association is trying to re-establish a popula- tion in Lagan by releasing the fish in a tributary river, Krokån. This paper investigates the eco- logical challenges that this project faces. I conclude that the water temperature could pose a big problem

Under en tid har det funnits en önskan att förtäta bostadsområden för att spara mark och minska utspriddheten. Detta har skett på både bättre och sämre sätt. I städer där grönskan är begränsad har den ofta fått ge vika för punkthus. Även om tanken bakom detta är god och många gånger har genomförts på ett balanserat och ansvarsfullt sätt växer diskussionen om hur vi vill bo. Att exploatera åkermarkFor some time now, there has been a desire to densify residential areas in order to save land and reduce sprawl. This has happened in better and worse ways. In cities where greenery is limited, it has often been done building upwards.. Although the idea behind this is good and has often been implemented in a balanced and responsible way, the discussion is growing about how we want to live. Exploit

När orden mörk materia nämns förs tankarna hos många till sci-fi böcker eller serietidningar. Kanske föreställer man sig en främmande substans i en provrör, eller ett destruktivt svart hål. Sanningen är att mörk materia är mycket mindre dramatiskt än så. Ett definierande drag hos mörk materia är att det interagerar ytterst svagt med vanlig materia. Troligen passerar mörk materiepartiklar rakt igenThe Light Dark Matter Experiment (LDMX) is a fixed-target missing-momentum experiment which hopes to detect dark matter in the MeV-GeV mass range. This is done by firing an 8 GeV electron beam at a thin tungsten target, where the electrons produce dark matter through a process called dark bremsstrahlung. Electrons which have gone through dark matter production can then be found by looking for miss

Denna uppsats undersöker hur artificiell intelligens (AI) uppfattas och anpassas i Kenya, med fokus på lokala språk, normer och kulturella värderingar. Syftet är att analysera i vilken utsträckning AI-system utvecklade i en global, ofta västerländsk kontext fungerar i kenyanska sammanhang och hur användare aktivt omformar tekniken. Studien bygger på nio månaders fältarbete i Nairobi och andra delaThis thesis examines how artificial intelligence (AI) is perceived and adapted in Kenya, with a focus on local languages, norms, and cultural values. The aim is to analyze the extent to which AI systems developed in a global, often Western, context function in Kenyan settings, and how users actively reshape the technology. The study is based on nine months of fieldwork in Nairobi and other parts o

Commercial hybridisation of seeds has created a large hybrid market that now dominates globally. In Rwanda, this market co-exists with a traditional system based on locally grown seeds. Local, farmer-grown seeds have traditionally been replanted to generate new seeds, which has kept farmers self-sufficient. Due to their genetic nature, hybrid seeds must be repurchased each season, creating a poten

Vår moderna värld är på många sätt och vis byggda på datorer, som möjliggör allt från kommunikation, ekonomiska transaktioner och underhållning. Dessa datorer bygger i sin tur på transistorer, halvledarkomponenterna som möjliggör de otaliga beräkningar per sekund som en modern dator utför. Våra vardagliga interaktioner med dessa datorer och mycket annat bygger dock på en annan sorts komponenter, nThe last decade and a half has seen intense research efforts into metal-halide perovskite (MHP) materials, as researchers have come to appreciate their excellent photo-electrical properties such as good radiative recombination rates and light absorption. As part of these efforts MHP-devices of different morphologies have been developed. Notably the enhanced nanophotonic effects of nanowire (NW) mo

Skuggdestinationer är platser som är belägna nära större etablerade turistorter med starka varumärken. Platser som befinner sig i periferin ställs inför utmaningar att synas och dra till sig besökare då många väljer att åka till de etablerade destinationerna. Efter pandemin uppstod en ökad vilja att besöka landsbygdsområden för att vara närmare naturen och få uppleva ett lugnare tempo. Intresset f

Studien undersöker den kortsiktiga aktiemarknadsreaktionen när amerikanska företag offentliggör förvärv i EU och vilka faktorer som förklarar förvärvarens kumulativa abnorma avkastning (CAR). Med en eventstudiemetodik finner vi att CAR i huvudfönstret (−15,+2) uppgår till 0,8 %, en effekt som är ekonomiskt relevant givet förvärvarnas storlek i studien. Avkastningsmönstret före annonseringsdagen ty

I vårt examensarbete undersöker vi varför vissa kvinnor lyckas nå toppositioner inom modebranschen medan andra kvinnor inte gör det. Studien fokuserar på modebranschen i Sverige och den är avgränsad till kvinnor som är verksamma inom olika delar av modebranschen. Vi valde modebranschen för dess tydliga könade och estetiska normer, vilket gör den relevant för att studera utifrån studiens syfte. Vi

This thesis introduces the theory of quasiconformal mappings on the plane. We give three different definitions of quasiconformal mappings: Differentiable quasiconformal map and two geometric definitions, one based on boundedness of the modulus of quadrilaterals and the other on ring domains. We also showcase when these definitions are equivalent. Then we prove that the geometric definition for qua

This study focuses on the chromatographic analysis of neonicotinoid pesticides in bumblebee samples. Analyzing these residues presents significant challenges due to the complex biological matrix and the critical need for high detectability to meet regulatory limits. Furthermore, many conventional chromatographic methods are often time-consuming and rely on substantial volumes of hazardous organic

Membrane fouling, particularly by soft, deformable particles, is a significant challenge in microfiltration (MF) processes, leading to reduced efficiency and increased operational costs. This thesis investigates the formation of filter cake layers by numerically simulating fluid flow through microfluidic membranes designed with random, non-overlapping cylindrical micropillar arrays. The study aims

De svenska kriminella gängen beskrivs idag drivas av jakten på status och det talas om en heder bland gängmedlemmar som upprätthålls genom våld och kontroll, särskilt av kvinnor. Därmed har denna studie i syfte att undersöka hur hedersrelaterade normer tar sig uttryck i svenska gängmiljöer, samt vilka könsspecifika konsekvenser som detta medför. Två semistrukturerade intervjuer med två svenska ide“If we’re the worst, we’re the strongest. Then we have the most power." Honour culture within Swedish criminal gangs and its impact on women Swedish criminal gangs today are driven by the pursuit of status, and there is talk of an internal honour among gang members that is maintained though violence and control, particularly of women. This study thus aims to investigate how honour-related no

This thesis aims to reproduce the ATLAS detector measurements of the top quark mass, which is done by removing background events in the ATLAS detector dataset that has been extracted from the ATLAS Open Data (AOD). Understanding how it is produced and decayed, and how it can be seen in the detector. The coding for this project was done in ROOT via C++. We used simulations and a theoretical backgro

Recognizing that the labor movement is under-theorized as a political subject in degrowth literature, this thesis investigates potentials for alignment between degrowth and the Swedish labor movement through a focus on policies. It hypothesized that the two, from a policy perspective, may hold positions that could mutually reinforce each other. Departing from 14 policies proposed jointly in degrow

This thesis explores how Chinese adoptees in Sweden negotiate their identity in a society characterized by a norm of whiteness. By collecting empirical research through seven interviews, it aims to shed light on Chinese adoptees and their experiences. Although transnational adoption discourse and research is fairly widespread in Sweden, there has not yet been made a lot of research about adoptees

This study investigates teachers’ perspectives on the use of gamification in programming courses at Lund University’s Faculty of Engineering (LTH), focusing on implementation within the Moodle learning platform. Using a qualitative approach, semi-structured interviews were conducted with instructors who integrate gamification elements such as points, levels, progress bars, and immediate feedback i

With Sweden and the EU aiming to reach net-zero carbon dioxide emissions by 2045 and 2050, the interest in carbon capture technology such as Carbon Capture and Storage (CCS) and Carbon Capture and Utilisation (CCU) is on the rise, not least in hard-to-abate sectors such as waste incineration. Several Swedish waste management actors are now considering CCS or CCU, among them Tekniska Verken i Linkö

This study explores how unit managers within municipal health and social care describe their leadership in relation to trust-based leadership and how they work to foster psychological safety within their teams. A qualitative approach was applied, with eight semi-structured interviews conducted with managers from different departments. The analysis draws on theories of trust-based leadership, psych

This paper aims to examine women as formal leaders in social work, focusing on their own experiences, perceptions, and management of expectations regarding leadership and how expectations affect the practice of their leadership. This paper is based on a gender perspective where the focus is on examining the importance of gender and gender in relation to, among other things, expectations and ideals
