De flesta av oss associerar nog kemikalier med något negativt, men sanningen är att kemikalier utgör en förutsättning för mycket av den välfärd som vi ser idag. Tvärtemot vad man kan tro, så är det inte bara i produkter som plast, färg, lösningsmedel, med mera som dessa förekommer, utan även i produkter som räddar liv, till exempel i utrustning inom sjukvården och för vattenrening. Därför är de meThe production and use of chemicals has grown exponentially over the past 50 years. Although the knowledge of hazards and risks associated with chemicals towards humans and the environment has increased, we know frightenedly little about how dangerous these might become when part of finished products. Companies now need to be more concerned about which chemicals exist in their products. For the co

The exposure to naturally occurring, radioactive noble gas radon is known to cause permanent damage in lung tissue. Lung diseases and prior radiation of lung tissue have been identified as contributing to a severe progression of COVID-19. As the COVID-19 pandemic also showed within Germany largely unexplained high spatial variation of mortality and infection rates, it was suggested that the incre

Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack. Coniferous forests are known to produce larger quantities of BVOCs, especially terpenes,

The effectiveness of decision-making processes has been enhanced by integrating multi-criteria decision analysis (MCDA) and geographic information system (GIS) methods to solve more complex spatial problems that were not possible to solve using conventional GIS methods. A spatial decision support system (SDSS) supports various stakeholders in the decision-making process, by processing data using

I wanted to have fun in the process, play with forms, elaborate my design language and learn/see new things. In the design process, the space around the object is as important to me as the object itself. Only through the right place/ light/surrounding objects, the object works properly. It should be itself but at the same time one with its environment. I thought a lot about materiality and immate

Globally, men tend to earn more money than women. Even in relatively gender equal countries like Sweden wage differences remain. This thesis examines wage differences through the lens of sectoral gender segregation by looking at different wage trajectories, sector-specific gender wage gaps as well as the relationship between gender shares and the gender wage gap within a sector for both public and

The purpose of this thesis is to examine online sexism as a phenomenon on Danish news media platforms on Facebook. Research have shown a transgression of gendered violence online that is often produced on social media. Studies concerning Danish discourses and sexism is approached to give an understanding of the extent of online sexism. Limited research exists and the following study will provide i

Luminiscensdatering är en väletablerad dateringsmetod inom geologisk och arkeologisk forskning. Dock är användandet av luminiscensdatering, mer specifikt optiskt stimulerad luminiscens (OSL), fortfarande underrepresenterat inom norsk arkeologi. Denna studie ämnar utreda lämpligheten av denna dateringsmetod som ett användbart alternativ för utgrävningar av Stenålderslokaler på den norska kusten. DeLuminescence dating is a well-established dating method within geological and archaeological research. However, the use of luminescence dating, and more specifically optically stimulated luminescence (OSL), is currently underutilised in Norwegian archaeology. This study set about determining the suitability of this dating method as a viable option for excavations of Norwegian coastal Stone Age sit

Purpose: The purpose of this exploratory qualitative research is: First, to explore what brands understand by metaverse and how they perform branding in this new context. Second, to investigate how established constructivist approaches to branding are performed within the metaverse. And finally, to define what decentralized branding is and how it is linked to a decentralized metaverse. Additionall

För att skapa nya krypteringsalgoritmer är man alltid på jakt efter svårlösta matematiska problem. Men är alla problem lämpliga? Uppsatsen behandlar Gröbnerbaser över ändliga kroppar och visar att de är inte lämpliga för att bygga säkra krypteringsalgoritmer. Vi undersöker flera möjligheter att knäcka den på Gröbnerbaser baserade krypteringsalgoritmen Polly Cracker, analyserar Differential AttackWhen building cryptographic systems, one is constantly on the hunt for hard to solve problems, but are all problems suitable? In this thesis we will take a look at Gröbner bases over finite fields and how they fail to provide a secure cryptosystem. We discuss several ways of attacking a Gröbner basis based cryptosystem named Polly Cracker, analyse the Differential Attack by Hofheinz and Steinwand

Hot Jupiters are gas giants under intense stellar radiation with short orbital periods of only a few days. Due to their large radii, hot temperatures, and large scale heights, hot Jupiters can be observationally characterised in detail through spectroscopy over an entire orbital phase. Transmission spectroscopy is one of the tools that aid us in understanding the complex chemistry of exoplanet atm

Particle collisions are an essential component to the research methodology of particle physics. These investigations are not only conducted in experimental laboratories but also through programs such as PYTHIA that simulate a collision or ``event" and then compare its results to known experimental data. This thesis aims to investigate the energy dependence of parameters used in PYTHIA's A

Organic waste forms a big share of municipal solid waste, especially in developing countries. Its management is however faced with many challenges ranging from limited financial and technical capacity to lack of, or weak policy enforcement. This causes poor management of the waste leading to open dumping and disposal in un-engineered landfills. Such practices have adverse effects on both the envir

Nowadays, research in autonomous drones has increased thanks to the advancement of drone technology. Nevertheless, there are still limitations when performing specific missions due to flight duration, computational load and mission complexity. This thesis investigates ways to solve this problem by taking advantage of multiple UAVs and UGVs. This thesis aims to implement and evaluate strategies for

This thesis investigated the ambitions of Japan in the space sector through the development of the country’s space programme. Drawing on content and discourse analysis of policy, law, strategy documents, the Japan Aerospace Exploration Agency website and documents about the ISS, this thesis explored how Japan has been articulating their space ambitions since 2000. It aimed at analysing the ambitio

In the ongoing transformation from previous “one-child policy” to current “two-/three-child policy” in China, the newly issued “supporting measures” system is highlighted to be crucial to boosting fertility. Extant studies on the issue are mostly limited to idealized discussions, while lacking a Public Administration perspective to comprehensively understand the real policy process. To compensate

Habitat destruction (evidenced in land use change) represents one of the biggest threats to environmental resources and biodiversity. In the tropics, this threat is maximized as deforestation frontiers have expanded into natural ecosystems at increasing rates over the last decades for agricultural cropping and livestock husbandry. Protected areas have been conventionally established against this g

Hemliga tvångsmedel är ett fragmenterat och komplext område inom svensk rätt. Lagstiftningen är utspridd i flera olika lagar med en stor mängd korshänvisningar. Dessutom görs en åtskillnad om hemliga tvångsmedel företas inom ramen för en förundersökning eller i preventivt syfte. Anledningen till att lagstiftningen ser ut som den gör torde vara på grund av den fortgående teknik- och samhällsutvecklSecret coercive measures are a fragmented and complex area within Swedish law. The legislation is spread across several different laws with a large amount of cross-references. In addition, a distinction is made if secret coercive measures are carried out during a preliminary investigation or for preventive purposes. The reason why the legislation looks this way is most probably because the ongoing
