Symmetry breaking is a crucial technique in modern combinatorial solving, but it is difficult to be sure it is implemented correctly. The most successful approach to deal with bugs is to make solvers certifying, so that they output not just a solution, but also a mathematical proof of correctness in a standard format, which can then be checked by a formally verified checker. This requires justifyi
Loess–palaeosol sequences (LPS) represent one of the most important continental archives of late Quaternary environmental change in Europe. Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (MAR) dataset for six key Polish LPS, based on
High-efficiency single-photon detection in the microwave domain is a key enabling technology for various quantum applications. However, the extremely low energy of microwave photons presents a fundamental challenge, preventing direct photon-to-charge conversion as achieved in optical systems using semiconductors. Here, we demonstrate continuous microwave photon detection with an efficiency approac
Despite being such an important factor for individual identity, Orthodox churches have not been sufficiently studied. In addition, the study of gender in these churches often seems formed by the impression that they do not change. This article therefore explores a seemingly static feature, the gendered seating in three Syriac Orthodox parishes in Sweden, from the point of view of space and agency:
By inspecting Diane Cook’s novel The New Wilderness, this thesis positions the practice of mothering within the larger Anthropocene humanities scholarship. While the Earth has often been mythologized as maternal, there has been a distinct lack of close attention paid to the cultural representations of lived experiences of mothers in the Anthropocene. Hence, this thesis begins by conducting a matri
This thesis analyses how the biblical motif of the deluge is portrayed in modern fantasy. I apply an ecocritical perspective on the deluge as a way to portray natural disasters and climate change. The intertextuality with the Bible and what that lends to the literary works is in focus for the analysis as well as what role the water has in the fictive material. Through the paper I discuss water as
Studien undersöker den möjliga världen som Carl Jonas Love Almqvists "Skaldens natt" utgör. Utgångspunkten för studien är de specifika textuella villkoren som "Skaldens natt" är konstruerad utifrån. Undersökningen ämnar att begripliggöra "Skaldens natt". Både alstrets inre egenskaperna som fiktion och konstruktion samt hur den fiktiva världen förhåller sig till genr
I takt med att allt fler användningsområden upptäcks ökar efterfrågan på biologiska läkeme-del i form av till exempel enzymer, antikroppar och virus. I många fall har biologiska läke-medel redan blivit standard i behandlingen av sjukdomar som diabetes, HIV/AIDS, samt vissa neurologiska sjukdomar. Dessa läkemedel kännetecknas av att de produceras av celler som har blivit genetiskt modifierade för aAs the market for biopharmaceuticals grows, the demand for continuous downstream pro-cessing (DSP) increases. This thesis tackled one of the key factors in successfully creating a continuous chromatography process: the ability to have an automated supply of complex buffer solutions. It aimed to develop and evaluate a Buffer Preparation Unit using an ÄKTA Pure machine, as well as the development of
Biografisk artikel om lundastudenten, biografägaren, läraren och astronomen Karl Oskar Krantz (1867-1933) med fokus på hans insats som filmpionjär inom genren karnevalsfilm.
CVD (chemical vapor deposition) coated cutting tools typically exhibit thermal cracks caused by the mismatch in coefficients of thermal expansion (CTEs) between coating and cemented carbide. These cracks act as weak points during stainless steel machining, contributing to premature tool wear. As a strategy to suppress thermal cracks formation, we investigate replacing the conventional cemented car
Sensory traits shape animal lifestyles due to the central role they play in retrieving and processing environmental information. However, being some of the most energetically expensive tissues to build and maintain, ecological demands often modulate investment in these organs. Evidence that ecology shapes the evolution of sensory traits is plenty, but is heavily biased towards vertebrates and has
In this study, we have investigated the dynamic behavior of colloidal rods within their isotropic phase, employing multispeckle ultrasmall-angle x-ray photon correlation spectroscopy (UA-XPCS) focusing on the understanding of the interplay between structure and dynamics at the nearest-neighbor length scale. While prior research has primarily focused on the structural aspects, our work addresses th
The effects of oxygen concentration on combustion of gases have been investigated on fundamental levels in several studies. However, the same type of fundamental studies has not been made for liquid or solid fuels due to complex relationships between flame structure and changing mass loss rates (MLR). In this study, an experimental setup is designed that allows for extended times of stable combust
This paper proposes a method for making generative art in the form of a system based on an interdisciplinary approach combining sculpture and sound. I will explore the possibility of using data from the spectral analysis of sounds as instructions for making sculpture. Inspired by Sol LeWitt's principles and ideas for the creation of generative art as system and Francis Halsall’s definition of a ‘s
Southern Africa is a global hotspot for hydrometeorological risk, with intensifying droughts and floods increasingly disrupting livelihoods, ecosystems, and infrastructure. This study presents a systematic bibliometric and scientometric synthesis of 1481 peer-reviewed publications on drought and flood hazards published between 2000 and 2024 across the Southern African Development Community. Using
