The relationship between international migration and the welfare state is a hotly contested topic: some scholars argue that migration will, in the long run, erode support for the welfare state; others argue that the welfare state has inherent qualities that insulate it from such erosion. We place this debate in historical perspective by exploring the period when the latent tension between cross-bo
Context: Data from the recently launched astrometric satellite Gaia will be coming in soon with the final data release expected in 2022. This will provide a very precise map of the Galaxy. The Solar system and Galaxy is thought to be filled with invisible bodies (planetesimals, planets, brown dwarfs, neutron stars, black holes, etc.) and they will affect the observations via gravitational lensing.
The Devonian appearance of 1-10 meter long armored fish (placoderms) coincides with geochemical evidence recording a transition into fully oxygenated oceans.1 A comparison of extant fish shows that the large individuals are less tolerant to hypoxia than their smaller cousins. This leads us to hypothesize that Early Paleozoic O(2) saturation levels were too low to support >1 meter size marine, pred
Memories of the transition Memories of the transition is fictive. However, it is knowledge-based speculation. Much of the story is inspired by existing proposals, emerging innovations, or research on the transformations needed to meet our climate targets. We have collected some of these imaginative seeds below so that you can understand and construct your own vision of a post-fossil society. Conte

The thesis elaborates on four different projects focusing on synthesizing symmetry-related molecules and investigating their performance as catalysts for asymmetric catalysis or as monomers for hydrogen bond-based self-assembly.Chapter 2 describes a new method to desymmetrize a meso-ligand. Two pseudo-Cs-symmetric bissalen complexes from a meso bissalen ligand and two different pairs of metal ions
Debt is commonly used by firms as a way of financing. Factors driving stock return have been the subject of numerous studies. Investors are constantly seeking ways to better understand stock return, which is where financial statements may provide them with relevant information. The presented research paper focuses on explaining whether there is a significant relationship between stock return and l
Massive MIMO can greatly increase both spectral and transmit-energy efficiency. This is achieved by allowing the number of antennas and RF chains to grow very large. However, the challenges include high system complexity and hardware energy consumption. Here we investigate the possibilities to reduce the required number of RF chains, by performing antenna selection. While this approach is not a ve
Reflection seismic data were acquired in the Sudret area of Gotland between 6 and 13 November 2023. Objectives of the survey were to obtain images of the subsurface down to the Precambrian basement in the vicinity of two cored boreholes that had been drilled earlier down to about 800 m. The seismic profiles were positioned to provide a better understanding of the sedimentary strata and local struc
Nitrous oxide (N2O) is a greenhouse gas formed during biological wastewater treatment under aerobic and anoxic conditions. Two reasons for high N2O emissions are low oxygen concentration during nitrification and low carbon/nitrogen-ratio during denitrification. In this full-scale study of N2O emissions from a sequencing batch reactor for treating digester supernatant, the oxygen concentration was Nitrous oxide (N2O) is a greenhouse gas formed during biological wastewater treatment under aerobic and anoxic conditions.

This study focuses on quantitative long-term effects of SupplementalInstruction (SI) in terms of graduation and dropout rates. One of the main aimsof SI is to introduce students to effective study strategies and techniques. If SIis introduced at an early stage for new students in higher education, it shouldtherefore be expected that this action will promote timely graduation. This hasalso been ind
Molybdenum complexes of 3,6-di-tert-butylcatechol have been prepared from the reaction between [Mo(CO)6] and 3,6-di-tert-butyl-1,2-benzoquinone. A putative "[MoO(3,6-DBCat)2]" monomer is assumed to form initially by reaction with trace quantities of oxygen. Condensation of the reaction mixture leads to the formation of oligomeric products, including the [{MoO(3,6-DBCat)2}4] chiral square isolated
Arsenal F.C., Manchester City F.C. and Newcastle United F.C. are three leading football clubs in the English Premier League. These three clubs are consolidated in terms of having a rich history, culture and traditions as well as local embeddedness. Douglas B. Holt’s contributions to the field of branding added a new dimension to how to operate a brand and are recurrently being used in new research
IntroductionSlow sand filtration is an established method for drinking water treatment, however, the knowledge about their microbial ecology remains limited. Maintenance of slow sand filters (SSF) includes washing to remove biofilm growth in the sand and restore flow through the filter. Understanding how this impacts produced water is important as the SSF may influence the bacterial flora in the f
