In response to the pressing need to address climate change and reduce global greenhouse gas (GHG) emissions, this study implemented Gaussian Mixture Models Clustering to detect the levels of GHG emissions and related socio-economic factors in 174 countries. To handle the panel data, Principal Component Analysis was conducted to achieve dimension reduction. Based on the algorithm, countries were gr
The thesis is to develop a 3D printer that easily and conveniently can print with recycled plastic such as PET bottles, plastic packaging and much more. The printer will be designed according to the needs of a developing country. The idea is not to create an additive manufacturing factory but an effective manufacturing tool for the locals in the less developed parts of the country. The printer can
Thesis Purpose: The purpose of this thesis is to explore the phenomenon of blands – A rise of brands that potentially adhere to a similar blueprint while claiming to be disruptive, unique and extraordinary. Moreover, this thesis aims to create an understanding of how consumers perceive blands as well as well as how value is created. Methodology: The methodology takes a social constructivist stan
The aim of this study was to analyze how young criminals are described and portrayed in Swedish news reporting and to identify discourses. We chose to analyze 19 different articles from four different Swedish newspapers. These newspapers were two morning papers and two evening papers. The criterias for our range of articles were that they needed to contain a description of crime and that the perso
COVID-19 was declared a world-wide pandemic in 2020, consequently affecting societies all around the globe. This thesis investigates one of these effects, namely how the pandemic affected occupant loads in office buildings and its subsequent effect on fire evacuation. Occupant load is one of many important factors when designing a building in regard to its fire safety, as it is a key component in
Det huvudsakliga syftet med detta arbete var att simulera tredimensionella flödesmönster i tankar för lagring av vatten. De praktiska avsikter med simuleringarna var att identifiera vattenkvalitetsproblem relaterade till bristande vattenutbyte. De vattenmagasin som reservoarer vid Norra Ugglarp i Skåne utgör undersöktes i en särskild fallstudie. I denna avhandling har den öppna CFD källkoden OpenFThe main purpose of this thesis was to simulate the three-dimensional flow patterns in tanks for water storage. The practical intentions of the simulations were to identify water-quality problems related to insufficient water exchange. The water storage reservoirs at Norra Ugglarp in South Sweden were investigated as a special case study. In this thesis, the open source CFD software OpenFoam was c
Populärvetenskaplig sammanfattning Morgondagens energi Vind-, och vattenkraft tillsammans med solenergi är de enda energikällorna vi har som inte leder till avfall som ökar växthuseffekt eller avfall som vi inte kan göra oss av (från t ex kärnkraftverk). Men solpanelerna som finns idag för kommersiellt privat bruk ligger på en effektivitet kring 15%. Att utveckla nya molekyler som kan omvanlda solThe aim of the study was to theoretically investigate if a proton coupled electron transfer (PCET) was feasible for a molecular system consisting of a light harvesting complex, ruthenium(tris-2,`2-bipy)2+, with different organic moieties serving as PCET (proton coupled electron transfer) relays. These light harvesting complexes are also sometimes referred to as dyes. By studying the energy levels
MAX-lab is a synchrotron radiation laboratory run in cooperation between Lund University and the Swedish Research Council. It currently consists of three stor-age rings, however, construction has begun of the fourth. MAX IV will be located outside of the Lund University Faculty of Engineering campus, in the northeastern part of Lund. Induced by the development in material technology at the nanomet
The aim of this master’s thesis is to examine how the Swedish model for production and distribution of talking books to the print disabled can be designed in the future, on the basis of the self-expressed needs of the users. Three questions were formulated in order to achieve this aim: 1. What needs do the users, according to themselves, have in relation to talking books to achieve equal means of
Abstract Peroxisome proliferator-activated receptor gamma (PPARγ) is expressed in multiple tumor cells as well as macrophages, and has been identified as a putative target for the development of novel therapies against colon cancer. Stimulation of the nuclear receptor PPARγ transcriptional activity can suppress colon carcinogenesis. To understand the molecular mechanisms underlying the anti-tumor
Large amounts of plastic in the oceans originate from mismanaged plastic waste, and microplastics (MPs) are the most common type of waste. They can be found in household products, such as sea salts. Therefore, monitoring pollution levels is essential to improve marine health and food safety. This study examined the MP levels in salts produced from the North Atlantic and North Seas and analyzed the
Purpose: This study aims to increase the understanding of how companies develop MaaS as a capability Theoretical Perspectives: This study is based on capability theory, with an emphasis on how to develop capabilities. This is combined with previous research on how to develop service capabilities, as well as research within the concept of MaaS. Methodology: Qualitative multiple-case study with an
This study examines what challenges organisations might face when supporting their employees in self-directed learning. Self-directed learning, SDL, is a learning process where learners are responsible for identifying their learning needs, setting learning goals, initiating the learning process and evaluating the results. Previous research has shown the benefits of having self-directed learners as
‘Fee & dividend’ (F&D) would incentivize the energy transition by levying an annually rising fee on fossil fuels. Simultaneously, all revenues would be given straight back to citizens, protecting a majority against price increases on products and services. Proponents say that this translates into broad popular support and makes the policy the most feasible option for realizing adequate car
This study uses qualitative research by documenting experiences of social workers work-related stress in a governmental organization. The aim of this research is to investigate how social workers experience sense of coherence and how that relates to stress in their work-place. Both of these will hopefully allow for a clearer picture regarding what factors can help create a healthy workplace. Semi-
The aim of this study was to describe and analyze how parents relate to their children’s internet use. Studies have shown that children nine years and older have increased access to private tablets and smartphones, leading to unsupervised online opportunities. With increased use, parents must take responsibility to protect their children from risks associated with the internet. We have examined; 1
This report describes a product development process of a carrier for mobile phones. The product development process is based on the description in Ulrich and Eppinger [1]. Including what steps should be followed to achieve a final product that meet decided requirements. The work is performed in cooperation with the company Medotemic AB. Through an application, the mobile phone can measure the user
The aim of this study was to highlight how in personal blogs people who grew up with one or both parents that misused alcohol or drugs narrated and described their experiences of how their daily lives was when they lived at home, how they cope with difficulties that occurred and how they described their past has affected their physical development in adulthood. The method I chose to analyze this w
