Okawangodeltat är södra Afrikas största våtmark och en av världens minst påverkade våtmarker. Kunskapen om hur våtmarkssystemet fungerar är begränsad, särskilt vad gäller halter av näringsämnen och omsättning av näringsämnen i de dominerande våtmarksväxterna. I den här studien presenteras analyser av kol- , kväve- och kiselhalter i Cyperus papyrus som är den dominerande akvatiska växten i stora deThe Okavango Delta is southern Africa’s greatest wetland and is among one of the most pristine wetlands in the world. There is moderate information about how this system functions, however, the research on nutrient concentrations and cycles is especially limited. This study provides new knowledge on the Okavango Delta by analysing samples of Cyperus papyrus, one of the main aquatic plants in the a

Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC). Tetra Pak® has been interested in resear

This thesis explores the characteristics and sustainability strategies of Danish companies with certified climate targets and the distinction with net-zero targets. The probability of having a net-zero target is modelled with three explanatory variables – life cycle assessments (LCAs), disruptive innovation, and carbon offsetting. The study is based on survey data gathered from thirty-four sustain

Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. Currently, significant research efforts are aiming to explore the facet and interface evolution and the correlation wit

The aim of this master’s thesis is to create knowledge about the occupational identity of academic librarians in relation to their work with open research data. Interviews with six librarians from six different Swedish academic libraries were performed and analysed with the use of occupational identity-theory and sociocultural theory. It was found that the informants of the study had a difficult t

In this thesis we will examine how to solve linear systems using the s-step biconjugate gradient algorithm, which is an iterative method based on the Krylov subspaces. It is useful especially when we have a large and sparse matrix. We begin looking over the biconjugate gradient algorithm (BiCG), in order to understand how to construct the s-step BiCG algorithm. We will go through some numerical ex

Vår studie genomfördes för att undersöka hur väl människor kan identifiera andra människors emotioner utifrån scenarier, där inga visuella signaler eller för mycket bakgrundsinformation gavs. Detta var för att simulera det konceptuella sammanhanget vi får i vardagen där mycket information inte är tillgänglig, men där vi ändå drar slutsatser om vad andra människors emotioner kan vara. Vi konstrueraOur study was conducted to investigate how well people can identify other people's emotions from scenarios where no visual cues, nor too much background information was given. This was to simulate the conceptual context we are given in everyday life where much information is not present yet we make inferences about what other people's emotions might be. We constructed a survey with 24 fict

Syftet med denna uppsats är att identifiera den rådande diskursen inom juridisk forskning på området artificiell intelligens (AI) och genus, och att diskutera för- och nackdelar med de lösningar forskare presenterat i relation till substantiell jämställdhet. De rekommenderade lösningarna identifieras genom en systematisk juridisk litteraturgenomgång av AI och genus. Genom att tillämpa teorin om soThe thesis aims to identify the dominant narrative within the legal research field of Artificial Intelligence (AI) and discuss the merit of the prevalent solutions offered by scholars in relation to substantive gender equality. The thesis finds the solutions from a systematic legal literature review covering AI and gender. It develops an analytical framework by applying the theory of social change

Title: Introducing Paper Pallets to the IKEA Food Supply Chain - What are the Potentials and Will the Temperature be Retained during Transport? Contribution: This thesis is produced with equal efforts from both authors, where each author has been involved in each and every step of the process. Problem description: Paper pallets with 50 mm feet have been used in IKEA Furniture for several years w

Onboarding processen blir allt viktigare på dagens arbetsmarknad och mer vikt läggs på dess utformning och relation till arbetsplatslärande. Tidigare forskning visar på att tankar om processen tidigt funnits men att fokus har förändrats under årens lopp. Nytt nu är att processen har blivit mer digital. Syftet är att öka kunskapen om de faktorer som i en onboarding process främjar nyanställdas lära

LFM30 - en lokal färdplan för att accelerera arbetet med att uppnå klimatneutralitet i byggbranschen Byggbranschen står för cirka en femtedel av Sveriges växthusgasutsläpp. Det är därmed en sektor inom vilket mycket kan, och måste förändras om Sverige ska kunna nå upp till de mål man åtagit sig genom den nationella implementeringen av Agenda 2030 och mål uppsatta i Parisavtalet. Sektorn är starktThe climate on our planet is changing, and with it the conditions for its people. As the need for housing grows, the construction sector will have to balance increasing environmental requirements with a continuous need for construction. In order to do so, Sweden has a national roadmap with set goals for climate neutrality. But the question of how to work toward the set up goals remain as there is

The aim of this study was to explore peer support and their role in Swedish mental health care as described by the user organization and the health care management. A document analysis of official documents produced by the previously mentioned stakeholders was performed applying organizational theory, role theory as well as professional identity theory. The present study found that the peer suppor

The main purpose of our study is to explore the ‘say-do’ gap between management and employees and investigate whether there is a consensus or dissensus between what is being said and done. In addition, we aim to gain an in-depth understanding of both managers' and employees' perceptions of the employee engagement’s supporting and hindering factors and the employee engagement initiatives.

The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. The h

The dimensions of cultural economics have been more and more discussed recently. This study aims to analyze the relationship between social tolerance and economic growth. Previous studies have discussed two main ideas. Firstly, social tolerance creates a creative environment that promotes innovation and entrepreneurship. Secondly, social tolerance lowers barriers to entry in human capital accumula

This paper evaluates the impact of reproductive health care restrictions on women’s labor market outcomes in the United States. We exploit the variation in restrictions on reproductive health care services across U.S. states and over time by using individual level data on fertility and labor market outcomes and state level data on reproductive health care restrictions. We apply a difference-in-dif

Artificial neural networks are prone to overfitting – the process of learning details specific to a particular training data set. Success in preventing overfitting through combining the L2 and dropout regularisation techniques has led to the combination’s recent popularity. However, with the introduction of each additional regularisation technique to an artificial neural network, there comes new h
