Markis Lagergren och katolicismen i Sverige I

Markis Claes Lagergren är en av den nyare svenska katolska kyrkohistoriens kanske märkligaste konvertiter. Han har i memoarverket "Mitt livs minnen" från 1920-talet skildrat sin konversion och sitt liv fram till 35-årsåldern, alltså perioden 1853 till 1887. Memoarerna bygger på hans dagboksanteckningar, vilka för den följande perioden utgivits i urval och som i original finns i hans samling på Nor

Children, teaching and the evolution of humankind

Social learning is essential for human evolution. To achieve such learning, cultural processes which trigger the development of active teaching and intergenerational transmission and accumulation of knowledge are needed. The understanding of how such systems and processes were developed over a long time is essential for our understanding of human evolution. The identification of children’s learnin

The effects of MEK1/2 inhibition on cigarette smoke exposure-induced ET receptor upregulation in rat cerebral arteries

Cigarette smoking, a major stroke risk factor, upregulates endothelin receptors in cerebral arteries. The present study examined the effects of MEK1/2 pathway inhibition on cigarette smoke exposure-induced ET receptor upregulation. Rats were exposed to the secondhand smoke (SHS) for 8 weeks followed by intraperitoneal injection of MEK1/2 inhibitor, U0126 for another 4 weeks. The urine cotinine lev

Measurements of the spin-orbit interaction and Landé g factor in a pure-phase InAs nanowire double quantum dot in the Pauli spin-blockade regime

We demonstrate direct measurements of the spin-orbit interaction and Landé g factors in a semiconductor nanowire double quantum dot. The device is made from a single-crystal pure-phase InAs nanowire on top of an array of finger gates on a Si/SiO2 substrate and the measurements are performed in the Pauli spin-blockade regime. It is found that the double quantum dot exhibits a large singlet-triplet

Influenza A virus evolution and spatio-temporal dynamics in eurasian wild birds : A phylogenetic and phylogeographical study of whole-genome sequence data

Low pathogenic avian influenza A viruses (IAVs) have a natural host reservoir in wild waterbirds and the potential to spread to other host species. Here, we investigated the evolutionary, spatial and temporal dynamics of avian IAVs in Eurasian wild birds. We used whole-genome sequences collected as part of an intensive long-term Eurasian wild bird surveillance study, and combined this genetic data

Frequency and patterns of reassortment in natural influenza A virus infection in a reservoir host

Influenza A viruses (IAV) can dramatically alter both genotype and phenotype at a rapid rate as a product of co-infection and reassortment. Avian IAV exhibit high levels of phylogenetic incongruence, suggesting high levels of reassortment in the virus reservoir. Using a natural-experimental system, we reconstructed relationships amongst 92 viruses across 15 subtypes from 10 Mallards in an autumn s

Evacuation modelling for underground physics research facilities

This document presents the results of a literature review performed in order to assess the suitability of different evacuation modelling tools for the calculation of evacuation times and assessment of fire safety in underground physics research facilities. This document is part of the research collaboration between Lund University and the European Organization for Nuclear Research (CERN), concerni

Improved outcome of patients with severe thalamic hemorrhage treated with cerebrospinal fluid drainage and neurocritical care during 1990-1994 and 2005-2009

INTRODUCTION: Patients with thalamic hemorrhage, depressed level of consciousness and/or signs of elevated intracranial pressure may be treated with neurocritical care (NCC) and external ventricular drainage (EVD) for release of cerebrospinal fluid.METHODS: Forty-three patients with thalamic hemorrhage treated with NCC from 1990 to 1994 (n = 21) and from 2005-2009 (n = 22) were evaluated. Outcome

Association between low-density lipoprotein cholesterol-lowering genetic variants and risk of type 2 diabetes : A meta-analysis

IMPORTANCE Low-density lipoprotein cholesterol (LDL-C)-lowering alleles in or near NPC1L1 or HMGCR, encoding the respective molecular targets of ezetimibe and statins, have previously been used as proxies to study the efficacy of these lipid-lowering drugs. Alleles near HMGCR are associated with a higher risk of type 2 diabetes, similar to the increased incidence of new-onset diabetes associated w

Diabetes mellitus, high BMI and low education level predict sudden cardiac death within 24 hours of incident myocardial infarction

Background More than half of cardiovascular mortality occurs outside the hospital, mainly due to consistently low survival rates from out-of-hospital cardiac arrest. Methods This is a prospective, nested, case-control study derived from the Västerbotten Intervention Programme and the World Health Organization's Multinational Monitoring of Trends and Determinants in Cardiovascular Disease study in

Auxin Acts through MONOPTEROS to Regulate Plant Cell Polarity and Pattern Phyllotaxis

The periodic formation of plant organs such as leaves and flowers gives rise to intricate patterns that have fascinated biologists and mathematicians alike for hundreds of years [1]. The plant hormone auxin plays a central role in establishing these patterns by promoting organ formation at sites where it accumulates due to its polar, cell-to-cell transport [2-6]. Although experimental evidence as

Exploring the Electronic Band Structure of Organometal Halide Perovskite via Photoluminescence Anisotropy of Individual Nanocrystals

Understanding electronic processes in organometal halide perovskites, flourishing photovoltaic, and emitting materials requires unraveling the origin of their electronic transitions. Light polarization studies can provide important information regarding transition dipole moment orientations. Investigating individual methylammonium lead triiodide perovskite nanocrystals enabled us to detect the pol

Following in Real Time the Two-Step Assembly of Nanoparticles into Mesocrystals in Levitating Drops

Mesocrystals composed of crystallographically aligned nanocrystals are present in biominerals and assembled materials which show strongly directional properties of importance for mechanical protection and functional devices. Mesocrystals are commonly formed by complex biomineralization processes and can also be generated by assembly of anisotropic nanocrystals. Here, we follow the evaporation-indu

An Evaluation of Information Meetings as a Tool for Addressing Fear of Large Carnivores

Managing authorities in Scandinavia arrange public information meetings when members of the public express fear because wolves or brown bears approach human settlements. This study aimed to increase the understanding of the potential effect of information meetings on self-reported fear of wolves and brown bears. In total, 198 participants completed questionnaires before and after the information m

Herbivore teeth predict climatic limits in Kenyan ecosystems

A major focus in evolutionary biology is to understand how the evolution of organisms relates to changes in their physical environment. In the terrestrial realm, the interrelationships among climate, vegetation, and herbivores lie at the heart of this question. Here we introduce and test a scoring scheme for functional traits present on theworn surfaces of large mammalian herbivore teeth to captur
