Människor spenderar mer än 90 % av livet inomhus. En innemiljö med god luftkvalitet är avgörande för människors välmående, både kort- och långsiktigt. Människor kan drabbas av bland annat huvudvärk, irriterade slemhinnor, hosta, andnings- och koncentrationssvårigheter orsakat av föroreningar i luften. Detta examensarbete kartlägger information och forskning inom ämnet luftkvalitet och hälsa i formThis thesis summarizes research within the subject of air quality and health in residential and public buildings. The work examines health effects and the relationship with ventilation systems, airflow rates, carbon dioxide, airborne particles and radon. The literature study was conducted using scientific articles obtained from the databases Web of Science, DiVA Portal and PubMed. Theoretical info

I kursen Arkitektur i tid och rum utreds befintliga byggnader och dess potential att förändras för nya funktioner och användningsområden. Transformation inom arkitektur blir allt vanligare och desto mer betydelsefullt ur ett hållbart perspektiv samt kulturhistoriskt värde. Att lyfta befintliga värden, addera nya samt anpassa byggnader efter behov kan garantera dess överlevnad, dämed bevaras. Konst

High-pressure homogenizers (HPHs) are widely used in the food industry for breaking down droplets and particles to improve product stability and mouthfeel. HPHs are prone to cavitation, characterized by the formation and collapse of vapor bubbles, leading to wear and reduction in efficiency. This study evaluates the potassium iodide (KI) oxidation method as a tool for measuring cavitation. The met

Denna uppsats syftar till att stärka förståelsen för dynamisk prissättning och dess möjligheter genom att undersöka effekterna på samhällsnyttan om dynamisk prissättning används inom kollektivtrafiken. Kollektivtrafiken har en stor påverkan på samhällsnyttan och är ett verktyg som kan bidra till att minska social exkludering. Det är därför av stor betydelse att utbudssidan av kollektivtrafiken max

Södra Sverige saknar planerbara energikällor. En gasturbin är en flexibel lösning på detta problem, men dess effekt kommer att variera beroende på var den placeras i det sydligaste elområdet SE4.In the SE4 bidding area in Sweden, there exist few sources of dispatchable power. The area relies on transmission from the north or intermittent production. The installation of a gas turbine could alleviate these issues in the near future and improve voltage stability and power transfer to the region. Depending on where this gas turbine is located, there will be differences in system performance.

I takt med att hållbarhet blivit en allt viktigare faktor i konsumtionsbeslut har även användningen av miljöpåståenden i marknadsföring ökat. Många företag framhåller sina produkter som "miljövänliga" eller "hållbara", men långt ifrån alla sådana påståenden har vetenskaplig grund. Fenomenet, känt som grönmålning, innebär att företag skapar en missvisande bild av sin miljöpåverkAs sustainability has become an increasingly important factor in consumer decision-making, the use of environmental claims in marketing has also risen. Many companies promote their products as "environmentally friendly" or "sustainable," yet not all such claims are based on scientific evidence. The phenomenon known as greenwashing occurs when businesses create a misleading impr

This thesis investigates using machine learning for estimating the infrared-to-visible light ratio (qIR) in images, which is used for day/night synchronization in surveillance cameras. Three different models were developed, namely a regression multilayer perceptron (RMLP), a regression-by-classification MLP (RbC MLP), as well as a gradient-boosted decision tree (GBDT). Using an internal dataset co

The telecom industry falls among one of the most progressive markets that operates at the level of advanced technologies and has the fastest rate of growth all over the world, including from the perspective of 5G technology, the integration of digital products, and the constant increase in demand for broadband internet. In such a competitive environment, customer attrition has been known to be a m

Inconel 718 is a widely used Nickel-based alloy in the aerospace sector. However, its exceptional mechanical properties make it a very difficult material for machining operations. Additive manufacturing presents itself as a promising alternative, as it would reduce the need for post-printing material removal by machining. However, not enough research has been done about the behaviour of this mater

Denna uppsats syftar till att utreda hur den varumärkesrättsliga konsumtionsprincipen påverkar möjligheten för en varumärkesinnehavare att hindra parallellimport av varor som redan har satts på marknaden inom Europeiska ekonomiska samarbetsområdet (EES). Enligt artikel 15 i varumärkesdirektivet (EU) 2015/2436 anses varumärkesrätten i regel förbrukad när en vara har introducerats i EES med innehavaThis thesis examines how the principle of trademark exhaustion influences a trademark owner’s capacity to block parallel imports of goods already released on the market within the European Economic Area (EEA). Under Article 15 of Directive (EU) 2015/2436, once a product has been legitimately placed on the EEA market with the trademark owner’s consent, the right is generally regarded as exhausted,

The Learning Loop is a Naturum situated in the historic Limhamn Limestone Quarry, designed as a visitor and exhibition center that fosters education and inspiration about the natural environment. Acting as a gateway to the site's unique ecological and cultural landscape, the project integrates learning and recreation to engage both the general public and educational institutions. This report p

Oil price forecasting is critical for financial markets, economic and geopolitical stability, and has a direct impact on the energy transition. Therefore, practitioners in the financial industry strive to understand the key drivers of the oil price and determine its best prediction model. This thesis investigates whether the exchange rates of oil-importing countries have predictive power in explai

Introduction: Dried blood spot sampling is an alternative way to conventional blood sampling that could potentially be a large benefit for certain patient groups. A good example is the transplanted patient group treated with the immunosuppressants everolimus and sirolimus. Background: The challenge is to develop a reliable quantification method based on this relatively novel sampling technique.

The search for greener ways of producing plastic has been a very popular field for the last few years. One avenue of research focuses on separating plastic production from the fossil fuel industry by finding bio-based alternatives. This is the case of the research conducted by our collaborators at Biotechnology who are trying to use Escherichia coli to produce 1,4-butanediol, a precursor to many p

Vad ska den svenska skogen räcka till idag? Varför ser den ut som den gör? Och kan vi sköta den på ett sätt så att fleras behov täcks? En parallell inläsning om regenerativ design och den svenska skogen står till grund i examensarbetet. Genom att identifiera skogens intressenter och gestalta en plats där de kan mötas undersöker projektet hur platsskapande kan leda till kulturella skiften. Vad händThis study aims to explore the current and potential uses of the Swedish forest, investigating the reasons behind its current state and examining potential management strategies to meet the needs of a diverse range of stakeholders. Drawing on principles of regenerative design, the thesis delves into the implications of creating a space where various forest stakeholders can converge and interact, p

Fragmentation from the extraction of bone marrow for consumption is a common phenomenon in archaeological assemblages, because of the high fat content of bone marrow, it was an important source of sustenance in prehistory. From the perspective of marrow fracturing, analysis of these fragmented refuse materials gives insight into the general strategies for harvesting bone marrow. The fragmentation

Shifting away from long-standing optimistic evaluations of team building activities, this thesis provides insights into the nuanced and contested roles of team building activities in the context of Chinese workplaces. By integrating the perspectives of the communicative constitution of organizations (CCO) with sensemaking theory, the study focuses on how employees make sense of team building activ
