Flux and symmetry effects on quantum tunneling

Motivated by the analysis of the tunneling effect for the magnetic Laplacian, we introduce an abstract framework for the spectral reduction of a self-adjoint operator to a hermitian matrix. We illustrate this framework by three applications, firstly the electro-magnetic Laplacian with constant magnetic field and three equidistant potential wells, secondly a pure constant magnetic field and Neumann

Structural basis of Cfr-mediated antimicrobial resistance and mechanisms for its evasion

The ribosome is an essential drug target as many classes of clinically important antibiotics bind and inhibit its functional centers. The catalytic peptidyl transferase center (PTC) is targeted by the broadest array of inhibitors belonging to several chemical classes. One of the most abundant and clinically prevalent mechanisms of resistance to PTC-acting drugs is C8-methylation of the universally

Autonoma Vapensystem och folkrätten - Problem, definition och överblick

Den här uppsatsen går igenom Autonoma militära system och dess unika utmaningar för den internationella rätten. Med ett fokus på användning, och utveckling av dessa inom ramen för krigets lagar angående ”jus bello”. Upp-satsen utreder ocskå frågan om vilken definition som bör användas, om det åligger ett s.k. ”responsibility gap” som är unikt för AMS och hur detta för-håller sig till frågan om indThis paper examines the issue of autonomous military systems and their unique challenges for international law, with a focus on the use and develop-ment of these systems in the framework of international regulation regarding “jus bello”. It also examines the issue of which definition of “autonomous military systems” should be used. The paper examines the question if there is a so called “responsib

The ever evolving automotive industry is pushing for further electrification of the vehicle fleet and the need for new electric drivetrains is therefore in high demand. The Formula Student competitions have also shifted their focus towards electric vehicles where innovative and efficient drivetrains are premiered in the design events. This master thesis work aimed to continue the development of Lu

Configuring ethical food consumers: understanding the failures of digital food platforms

Digital food platforms are being launched, offering consumers convenient access to ‘ethical’ food. Ensuring the viability of these platforms hinges on attracting and retaining loyal customers. However, recent studies show that despite considerable efforts from market actors, stable platformconsumer relationships are rare in these digitalized food markets. The aim of this paper is to explore and ex

Relationship between nitrate, heavy metal, and sterols contents in Japanese agricultural soils with risk of groundwater pollution

In Japanese agricultural lands, nitrate-nitrogen contamination of soil and groundwater often occurs due to the application of livestock excrements and compost. Therefore, rural soils in Japan were sampled and analyzed for nitrate-nitrogen leaching, heavy metal content, and sterols associated with livestock excrement and compost to calculate contamination risk indicators. The results were analyzed

The Lasso and Ridge Regression Yield Biased Estimates of Imbalanced Binary Features

Many regularized methods, such as the lasso and ridge regression, are sensitive to the scales of the features in the data. As a consequence, it has become standard practice to normalize(center and scale) features such that they share the same scale. For continuous data, the most common strategy is standardization: centering and scaling each feature by its mean andand standard deviation, respective

Examining E-banking Use in Yemen: A Quantitative Study from the Perspective of the Unified Theory of Acceptance and Use of Technology 2

This thesis uses a quantitative method to explore the factors that influence the use of electronic banking (e-banking) in Yemen, considering the role of socioeconomic conditions and technological accessibility. By using an adapted Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model, the study examines how performance expectancy, effort expectancy, social influence, facilitating con

Acceptance factors influencing the willingness of multiple eID usage in Sweden: An analysis of factors influencing acceptance and adoption of alternative eID solutions to BankID in Sweden

This study aimed to examine the factors that influence the Swedish people’s willingness to adopt multiple eID services. Utilizing the Unified Theory of Acceptance and Use of Technology (UTAUT) as a foundational framework, we combined insights from previous research to design our survey, which received 300 responses divided into several age categories. This quantitative approach allowed for a broad

Den finska arbetsmarknadsmodellen under press

Den nya högerledda regeringen i Finland under Petteri Orpo är i full färd med att göra genomgripande förändringar av den finska arbetsmarknadsmodellen. Det handlar om konflikträtten, lönebildningen, förhandlingssystemet och de sociala förmånerna:•Begränsad rätt till sympatiåtgärder och politiska strejker samt kraftigt ökade böter i samband med olagliga konfliktåtgärder•Statliga medlare får inte go

Nos últimos anos, houve uma repressão contra defensores do meio ambiente em Uganda. Jornalistas, estudantes, agricultores e moradores da zona rural defendem o ambiente natural, protestando e mobilizando-se contra o tratamento injusto e a migração forçada causada por infraestruturas de combustíveis fósseis, agronegócio, energia hidrelétrica ou compensação de carbono. Essa situação colocou as autori

Hydrological and erosional dynamics: Responses to changes in land uses and climate in the Cerrado biome

The Brazilian Cerrado is the major national epicenter for agricultural production and a main contributor to the Brazilian economy. Thus, the biome faces increasing pressure from agricultural expansion that alters local and regional hydrological processes (infiltration, runoff, evapotranspiration, soil loss). There is a lack of understanding how these processes will respond to climate change. Conse

Land tenure formalisation and perceived tenure security: : Two decades of the land administration project in Ghana

Ghana’s Land Administration Project (LAP), initiated in 2003, aimed to enhance certainty regarding land rights. What has been achieved since then? We explore landowners’ perceptions of tenure security in Ghana using micro-level data from two waves of the Ghanaian Living Standards Surveys: GLSS5+ (2008) and GLSS7 (2017). This data allows us to study the linkages between land title formality and per

Chlorophyll biosynthesis in barley : Studies on the cyclase and chlorophyll synthase steps

The well-known green color of plants is due to the chlorophyll molecules used for light harvestingduring photosynthesis, which takes place in chloroplasts. Biosynthesis of chlorophyll a is performed by15 enzymatic steps and chlorophyll a can be interconverted to chlorophyll b via the chlorophyll cycle.Barley is a valuable model organism for studying chloroplast development and chlorophyll biosynth

Tattoos as a risk factor for malignant lymphoma: a population-based case–control study

Background The popularity of tattoos has increased dramatically over the last few decades. Tattoo ink often contains carcinogenic chemicals, e.g., primary aromatic amines, polycyclic aromatic hydrocarbons, and metals. The tattooing process invokes an immunologic response that causes translocation of tattoo ink from the injection site. Deposition of tattoo pigment in lymph nodes has been confirmed

New and noteworthy lichen-forming and lichenicolous fungi 13. A revision of the Xanthoria ectaneoides complex (Xanthorioideae, Teloschistaceae) including the new species Xanthoria pylyporlykii.

Xanthoria ectaneoides, usually recognised by its secondary sublobules, is circumscribed in a strict sense using spore size and a molecular phylogeny based on ITS-sequences. The spe- cies, earlier considered a synonym of X. aureola, forms a subclade with X. coomae and the new species X. pylyporlykii, described here, whereas X. aureola is positioned in the Xanthoria calcicola subclade. The new speci
