The Janzen–Connell hypothesis states that seedling survival increases with distance from the parent tree, which promotes regular spacing of species within a forest and thus biodiversity. Very few studies have tested this hypothesis in tropical Africa. This paper evaluates the occurrence of Janzen-Connell effects for seedlings and adult trees of the species Cola cordifolia in a dry tropical forest
Maskininlärning för att beräkna bankers risk Att banker har koll på sina risker är centralt för stabiliteten av den moderna globala ekonomin. Detta visar bankkriser gång på gång. En av riskerna som är ofrånkomlig för all bankverksamhet är kreditrisk – risken att handelspartners inte fullföljer betalningar. Detta examensarbete visar hur en aspekt av kreditrisk, exponering, kan modelleras med hjälpExposure modelling is a critical aspect of managing counterparty credit risk, and banks worldwide invest significant time and computational resources in this task. One approach to modelling exposure involves pricing trades with a counterparty in numerous potential future market scenarios. Suitable for this type of pricing is a framework presented in 2020 by Huge and Savine, which they call differe
The area of Västra Hamnen within Malmö municipality has since the area’s reconstruction, from industrial harbour grounds into a residential area in 2001, been regarded as the city’s frontrunner in sustainable urban planning. In this role the area has worked to garner much international attention for Malmö, while at the same time becoming one of the most exclusive areas in the city, with some of th
Tetra Pack Technical Services provides spare parts for Packaging and Processing product segments. Despite similar inventory management, the processing segment consistently has a lower spare parts service level. Understanding the reasons behind this disparity is crucial, especially with the anticipated increased growth of the Processing segment in the future. The purpose of this thesis is twofold
The goal of this thesis work is to describe the methods used and perform comprehensive testing of the Double-Sided Silicon-Strip Detectors (DSSD) prior to their implementation in the Lund-York-Cologne CAlorimeter (LYCCA) detector. In the framework of this project, the DSSD characterisation was carried out to ensure specification compliance prior to their "in-kind contribution" delivery t
Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. By introducing an enzyme-based sunscreen for daily facial use these damages may be reduced while also providing exfoliation and hydration
År 2007 släpptes världens första smartphone. Bara 16 år senare har näst intill varenda människa i Sverige en mobiltelefon i deras ficka. Sakta men säkert har mobiltelefonen blivit en del av vår vardag som ett av våra mest basala behov. Den digitala utvecklingen har gått så pass fort att vi ännu inte känner till vilka risker och möjligheter mobiltelefonen utgör för människan och vårt samhälle. Den
Despite the growing recognition of sustainability in business, industry research lacks behind in how businesses can integrate sustainable practices. This master thesis aims to investigate how managers in two different types of businesses, namely born sustainable businesses and becoming sustainable businesses, manage sustainability. The study begins with a comprehensive literature review that explo
Åldern för jordens inre kärna är en gåta som har förbryllat forskare i många decennier. Allt från en ålder lika hög som jordens magnetfält (mellan 3,5 och 4,2 Ga) i den ena änden, ner till 0,5 Ga i den andra änden. Eftersom den inre kärnan existerar på en fullkomligt oåtkomlig plats i jordens innersta centrum, medför detta självklara svårigheter när det kommer till direkta observationer (med seismThe age of the Earth's inner core is an enigma that has puzzled scientists for many decades. Everything from an age as high as the Earth's magnetic field (between 3.5 and 4.2 Ga) at one end, down to 0.5 Ga at the other end. Since the inner core exists in a completely inaccessible place in the innermost center of the Earth, this presents obvious difficulties when it comes to direct observat
Recent scholarship has challenged the notion that digital tools alone can sustain a social movement, emphasizing instead the importance of collective identity and organizational structures. However, there is still limited understanding of how organizational structures emerge and transform in a social movement. This study argues that despite appearing chaotic or disorganized, collective actors poss
The Antonine itinerary was compiled in the early fourth century CE and is a key source to our know¬¬ledge about ancient geography and the Roman road system. However, the major research work dates more than 100 years back in time and few studies have been focussed on its overall reliability. The aim of the present work is to assess the accuracy of the distance figures in the itinerary by internal v

The objective of this research is to explore returnee entrepreneurship, specifically focusing on individuals who studied abroad and started a new venture in their home country. By investigating the entrepreneurial dynamics among returnees, this study seeks to gain a deeper understanding of this specific phenomenon. To gather comprehensive and insightful data, a qualitative study with semi-structur
The aim of this project is to develop a method to detect metal objects with measurements from a magnetic sensor that is attached to a drone. This is challenging due to disturbances from currents and metal parts in the drone and the measuring equipment as well as the influence of the Earth's magnetic field. The measurements are also negatively affected by instability in the drone due to, for ex
This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. Then we set up the system and discuss the relevant approximations. Moreover analytical expressions of the c
En viss typ av immuncellsansamling i tumörer, så kallade tertiära lymfoida strukturer (TLS), hos patienter med bukspottkörtelcancer verkar inte alltid vara så gynnsamt som forskning tidigare visat. Förekomst av många TLS i tumören kunde i studien kopplas till kortare överlevnad och kan möjligen bero på att cellgiftsbehandling förändrar funktionen TLS. I denna studie studerades två typer av immuncPancreatic cancer (PC) is a devastating disease and is almost always synonymous with a poor outcome. Chemotherapy is the standard treatment and is administered in either an adjuvant or palliative setting. However, nearly all patients, regardless of treatment intent, eventually develop chemoresistance. Little is known about the events causing chemoresistance, but increased knowledge is essential fo
This essay examines the European Parliament resolution of 5 May 2022 on the impact of the war against Ukraine on women. The analysis is based on a descriptive idea analysis, which helps me map out which ideas and political actions that are adopted by the European parliament in the resolution. The essay also investigates the EU:s understanding of female exploitation and vulnerability in the Ukraini
Bilismen ökade explosionsartat under det svenska 1900-talets mitt. För att möta bilens utökade ytkrav och den olycksvåg som drabbade Sverige skulle samhället moderniseras och rekonstrueras, och det fort. Föråldrade kvarter revs, nya förorter anlades med bilen i åtanke och motorvägar såg dagens ljus. Samtidigt integrerades bilen med näringslivet, skapande köpcentra och industrier. Den fysiska miljöThe expansion of automobile usage in the middle of the 20th century gave rise to a car-centric planning, changing the Swedish society. New considerations and ideas favoured motorised planning, creating a car dependency and marginalisation of active transport like cycling. As a result, cost-benefit analyses are disregarding the benefits of cycling, making bicycle projects such as bicycle highways s
The UK government is legally bound to reach net zero greenhouse gas emissions by 2050 as part of its actions to address climate change. One prominent method of decarbonisation is carbon capture and storage (CCS), slated for deployment in two industrial clusters by the mid-2020s. Fossil fuel companies are the operator behind the rollout of this technology: given the historical reticence of these co
