Bitcoin mining är en industri som i flera år har kritiserats för sin elkonsumtion, som globalt idag motsvarar elkonsumtionen hos små länder som Sverige, och det tillhörande klimatavtrycket. Elkonsumtion är dock inte alltid likställt med växthusgasutsläpp och få studier har gjorts kring ämnet med fokus på Sverige. Detta är bakgrunden till arbetets genomförande som ämnar att bidra med nya rön till dBitcoin mining is an industry which for many years has been criticized for its electricity consumption, which globally today equals roughly that of small countries such as Sweden, and its subsequent contribution to climate change. However, electricity consumption does not by default equals greenhouse gas (GHG) emissions and not many studies have been done on the subject with a focus on Sweden, he

Cancer är idag det näst vanligaste dödsorsaken i världen, där 30% av alla cancerfall bland kvinnor är bröstcancer. En vanlig behandling är bröstbevarande operation, där en bit av bröstet kirurgiskt tas bort. Operationer är både dyrt och har en betydande inverkan på kroppen och för vissa kvinnor krävs en omoperation efter den första operationen. Syftet med detta arbete har varit att undersöka möjliCancer is the second leading cause of death worldwide and 30% of all cancer cases among women are breast cancer. A popular treatment is breast-conserving surgery, where only a part of the breast is surgically removed. Surgery is expensive and has a significant impact on the body, and on some women, a reoperation is needed. The aim of this thesis was to see if there is a possibility to predict whet

Decoration has been central to architecture throughout history. Since the beginning of the 20th century, the question of ornament in architecture has been oscillating between the positions of redundant and essential. With rapid advances in computational technology, the practice of architecture has been provided with new tools for designing buildings. This thesis aims to examine how digital design

The purpose of this paper is to interrogate the single and joint effect interest and exchange rate movements have on banks’ stock returns. This study also aims to compare the volatility of the banks’ stock returns for countries in different markets using both the short and long-term interest rate and the respective exchange rates. To conduct our tests, we use a sample of 14 German and 11 South Afr

Local perceptions on global scale problems are often overlooked, focusing the attention instead on policy action or scientific reports. To challenge that, this thesis focuses on Menorca’s population, specifically on whether place attachment is related to the perception of climate change impacts in the territory and if this can translate into concrete local action against its impacts. For that, I u

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.

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
