More than 17.9 million new patients worldwide suffer from heart diseases. In order to conduct a proper diagnosis and treatment, it is necessary to develop a functionality for patients and doctors, which has the possibility to transfer the continuously measured data to the doctor for several days. In addition, such a tool should have the function to wirelessly transmit an alarm to the doctors, prov
GAs in Scattering Media Absorption Spectroscopy (GASMAS) is a technique to study free gas inside strongly scattering bulk-materials. GASMAS is successful in safely measuring oxygen in lungs of neonates, with low-power tuneable diode-laser spectroscopy at 760 nm. Because a similar need of lung monitoring exists in older patients, this work explores how GASMAS can be scaled up for larger geometries.
Introduction: Gas chromatography-mass spectrometry (GC-MS) is a powerful tool when used in metabolomics, the study of small molecules in the body, and investigating new modes of using it might lead to even better tools for diagnostics and research. Background: Chemical ionization (CI) for GC-tandem MS (GC-MS/MS) is relatively rarely used compared to the more commonplace electron ionization (EI).
The availability of energy is an overarching measure connected to various aspects of poverty. Energy Poverty, as a concept, captures the deprivation of access to energy, clean and safe fuels and end-appliances. While measures to reduce energy poverty increase the demand for energy, greenhouse gas emissions must decrease to mitigate the worst impacts of climate change, rendering renewable energy so
Titel: Digitaliseringens påverkan på redovisningsarbetet: En kvalitativ studie av digitaliseringens påverkan på redovisningsekonomens arbetssätt och kompetensutveckling Seminariedatum: 2022-06-03 Ämne/Kurs: FEKH69, Företagsekonomi: Examensarbete i Redovisning på kandidatnivå Författare: Florentina Balaj, Vjosa Maloku & Albulena Shabanaj Handledare: Caroline Hellström Examinator: Elin Func
This thesis’ main goals were to provide accurate forecasts and informative physical parameter estimates for energy use of the district heating in the Tingbjerg neighborhood, Copenhagen. Our work is aimed as a contribution for future work towards efficient on-demand energy production. We applied Dynamic Double Machine Learning to estimate the causal effects of weather observations on energy use. Th
Objective: The Dark Factor of Personality (D) measures the underlying core of all aversive traits. The present study evaluated the psychometric properties of the Swedish version of three item sets D70, D35, and 16 in regard to their factor structure, item quality and functioning, reliability, and convergent and discriminant validity. Method: A convenience and prolific sample (N = 294) was analyze
Sustainability is a term of significant relevance in today’s global context, permeating discourses and management decisions, and influencing decision-making at the head of most industries. This is particularly apparent in relation to fashion. Second hand clothing is often portrayed as a model towards sustainable consumption, reducing personal environmental impacts while signifying good ethics. Cri
This paper examines the properties of Carmichael numbers with the aim of constructing an algorithm for computation. This includes a recently published characterization, whose applications in computing are studied. The resulting algorithm is then described and a run time comparison with an older algorithm is presented.
The study explores the influence of agro-processing activities in the lives and livelihoods of cassava farmers in five communities located in four districts in the Ashanti and Volta regions in Ghana. The qualitative research is done by performing thirty-six semi-structured interviews to farmers and stakeholders along the cassava value chain. The research concludes that agro-processing activities a

In Lusaka, 70% of the residents live in unplanned settlements. Here, they are regularly exposed to flooding events which exacerbate existing development challenges and have adverse social and economic impacts. Climate change will likely increase the frequency, magnitude, and variability at which such flooding events occur. Therefore, Lusaka City Council has declared the building of community flood
In this thesis, we study the Higgs mass spectrum and spontaneous CP violation, where one of the Higgs vacuum expectation values acquires a non-trivial phase θ in a Type-I 2HDM. We begin by investigating CP violating effects at tree-level, and then expand our studies by taking into account one-loop radiative corrections. After imposing tadpole conditions we discover that this model gives the same m
Den här studien handlar om att öka förståelsen för den interaktion som sker på Instagram. Instagram är en applikation och social plattform där miljontals bilder, videos och texter publiceras varje dag. Det finns en pågående debatt om vad detta får för påverkan, positiv såväl som negativ. Instagrams alla funktioner innebär nya tillvägagångssätt för hur vi människor interagera med andra. För att få
Abstract—For those living today with severely malfunctioning heart valves, replacement is the only available treatment. Patients are today typically offered either mechanical valves, xenograft or allograft. Decellularized heart valves have the potential of becoming one of the standard alternatives for such heart valve transplants. Decellularized heart valves offer a reduced risk of calcification a
Exploring the contributing factors of economic growth is a long-standing research field in economic study. However, natural capital stock has been widely excluded from this investigation. This thesis attempts to include natural capital stock in an augmented Solow growth model utilizing Swedish national accounts from 1850 to 2010. The model found that Swedish natural capital stock played a limited
Introduction Skin metabolomics may serve as a powerful tool to evaluate the physiological changes oc- curring in the body as a range of compounds, coming from inside the body, are retained in the skin. Background The diffusion kinetics of metabolites across the skin, the composition of the skin, the metabolites released as a consequence of different illnesses as well as the relationship be- tween
Deprivations and inequalities caused by poverty have social and economic consequences that prevent the poor from affording the most basic needs and thus, their eradication is crucial for a more equal world. However, existing studies on rural poverty in low-income nations are rare and often focus on the impact of economic indicators. Using the mixed methods of combining quantitative data with docum
Arctic amplification (AA) is defined as the enhanced warming of the surface temperatures in the Arctic region relative to the globe or Northern Hemisphere (NH) in response to external forcings. It is a prominent feature of the climate system. Various metrics have been used in studies to quantify AA, and this introduces a challenge when comparing studies due the differences in AA magnitudes. This s
