Transient Receptor Potential Ankyrin 1 (TRPA1) is a nonspecific cation channel activated by a wide range of stimuli. The polymodal receptor resides in the cell membrane of sensory neurons and plays a key role in nociceptive pain transmission. Environmental irritants such as allyl isothiocyanate, an electrophile found in wasabi, activate TRPA1. In this work, the goal was to lay the basis for struct
Drainage units are measures that permanently modify the water conditions of the land. This is done through drainage or dikes to make the soil more suitable for use by removing unwanted water. Drainage units shall fulfill the purpose of permanently increasing the suitability of a property for a specific purpose. A joint drainage unit is a drainage unit commonly used by several properties. For execu
At the turn of the twentieth century, Swedish painter Eugène Jansson created a series of paintings inspired by the city nights of Stockholm. This bachelor thesis examines the paintings in relation to urban gay spaces and sexual meetings in the early nineteen hundreds. The paintings by Jansson, himself a homosexual male, have at a few times vaguely been described as portraying the moments before an
Spain, Portugal, and Greece have experienced a rise of challenger radical left-wing parties alongside an already established radical left-wing in the 2000’s. This prompts the question how the new and established radical left differ in positioning and salience on the economic and cultural policy dimension. Using quantitative empirics from the Chapel Hill Expert Survey and the Manifesto Project Data
The aim of this thesis was to develop a biologically inspired model for unsupervised learning on visual data. A preprocessor inspired by the retina was developed, which generated event-camera like data. This can be used as a low-cost alternative to an event-camera. Further, a neuron model was developed which showed ability to learn useful features from video data in combination with the preprocess
A continuous growth of the world population raises the importance of preserving food resources while maintaining their nutrient value. Leafy vegetables such as spinach are a food category which decay quickly, and a large amount ends up as food waste. Therefore, shelf life extension while keeping a good product quality is of great interest in food processing. In this study, the effect of combining
Background: Color vision is enabled by visual opsins, a class of G-protein coupled receptors expressed in the eye. How well an organism discriminates color depends notably on the number of opsins, and their spectral sensitivity when bound to a light-sensitive chromophore (retinal). Spectral phenotypes have evolved convergently multiple times owing to opsin gene losses and duplications, both in ver
Araceae is one of the most abundant species families in South America with over 2200 species across the continent, yet it has not been given much attention in ecological investigations. I analysed the species diversity and abundance of araceans along an altitudinal transect between 400 and 2350 m altitude. The transect, made up of 7 different sites, was located in the Cloud forests of the Ecuadori
The impact of climate change is increasingly being investigated over elevational gradients as they provide natural laboratories to study how species of plants and animals respond to changes in temperature, precipitation and other factors. Ferns are especially sensitive to air humidity and temperature and can therefore serve as potentially useful bioindicators. To better understand how species comm
Due to their aberrant growth behavior, cancer cells maintain and depend on aerobic glycolysis even in the presence of physiological oxygen levels to provide building blocks for cell proliferation. This and other dependencies in the metabolism of cancer cells have emerged as promising targets for therapy development. However, metabolic interventions also target highly proliferating cells of the imm
Having access to dense reconstruction of ongoing building constructions provides insight into the building process and could serve as both a tool for error detection and documentation of the actual outcome. In this thesis, Spot, the quadruped robot designed by Boston Dynamics is evaluated as a platform for site inspection. The result of the thesis was a prototype system built on top of the ROS fra
The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. This, in addition to modeling flexibility from the switches, poses the NEO mo
The circulating fluidised bed boiler (CFB) consists of developing the combustion of a mass of fuel, in this case biomass, within a bed of particles in suspension, which have been fluidised by an ascending air current. Combustion occurs in a controlled manner throughout the entire furnace at temperatures around 850 ºC, which is lower than in conventional boilers, reducing NOx emissions. However, NO
This thesis examines the challenges that women human rights defenders (WHRDs) in Bangladesh are experiencing in a period of shrinking civic space. It further focuses on how perceptions guide their chosen strategies. Applying political opportunity theory, drawing from social movements research, it explores the structural changes in the political system and how it impacts civil society action. Thus,
Hamilton tells the story of the life and career of Alexander Hamilton, an immigrant who came to America at a young age and grew up to be a founding father as well as the first Treasury Secretary of the United States of America and the face of the US ten-dollar bill. Since premiering in 2015, the hip-hop-musical grew into a popular culture phenomenon, resonating with people all over the world while
The combustion of lignite coal for energy production significantly contributes to Germany’s greenhouse gas emissions, leading climate justice activists to advocate for an immediate coal exit. Workers of the lignite industry strongly oppose this as they worry about the structural decline of mining regions and their financial security. The concept of Just Transition is increasingly employed to bridg
In 2000, a 5-kilometer-long exercise path called Elljusspåret was constructed in Skrylle, Sweden. Excavations of the soil on the right side of the path were made to install lampposts. A large number of Primula veris emerged from the excavated soil. This re-evaluation investigates if the P. veris population still favours the excavated side and if it could be due to change in the soil horizon chemis
The internet brings a multitude of opportunities for information access, communication, and mobilization. Many studies point to the democratizing effect of the internet in that it increases political participation among citizens. However, much of this evidence is produced on a Western context where the penetration of the internet is well-established. This thesis examines the effect of internet use
