Vi 40-talister var solidariska – med oss själva

De politiska partiernas analyser av valet för ett år sedan lider alla av samma fel: de är för kortsiktiga. För att tolka valutslaget behövs ett långsiktigt och demografiskt perspektiv. Då hamnar fokus oundvikligen på 1940-talets baby boomers. Vi som föddes under 1940-talet har utgjort den centrala marginalväljargruppen under hela vårt vuxna liv. I ett extremt proportionellt valsystem som det svens

Strain-specific metabarcoding reveals rapid evolution of copper tolerance in populations of the coastal diatom Skeletonema marinoi

Phytoplankton have short generation times, flexible reproduction strategies, large population sizes and high standing genetic diversity, traits that should facilitate rapid evolution under directional selection. We quantified local adaptation of copper tolerance in a population of the diatom Skeletonema marinoi from a mining-exposed inlet in the Baltic Sea and in a non-exposed population 100 km aw

Improving the Thresholds of Generalized LDPC Codes With Convolutional Code Constraints

CC-GLPDC codes are a class of generalized low-density parity-check (GLDPC) codes where the constraint nodes (CNs) represent convolutional codes. This allows for efficient decoding in the trellis with the forward-backward algorithm, and the strength of the component codes easily can be controlled by the encoder memory without changing the graph structure. In this letter, we extend the class of CC-G

Ultrafast Jahn-Teller Photoswitching in Cobalt Single-Ion Magnets

Single-ion magnets (SIMs) constitute the ultimate size limit in the quest for miniaturizing magnetic materials. Several bottlenecks currently hindering breakthroughs in quantum information and communication technologies could be alleviated by new generations of SIMs displaying multifunctionality. Here, ultrafast optical absorption spectroscopy and X-ray emission spectroscopy are employed to track

Multidisciplinary approaches to identifying and managing global airways disease : Expert recommendations based on qualitative discussions

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma frequently co-exist and share pathologic features. Taking a “global” treatment approach benefits diagnosis and treatment of both, but care is often siloed by specialty: joined-up clinics are uncommon. Our objectives were to explore expert opinion to give practical suggestions to identify adults needing global airways care; en

Review of exergy and energy analysis of fuel cells

Recently, to reach zero emission levels, some new energy systems based on fuel cells have been developed. This paper presents a review of investigations of these systems by thermodynamics performance, mainly, energy and exergy analysis. With energy analysis, the performance of an energy conversion system cannot be effectively and accurately evaluated. But exergy analysis complements and reinforces

Effects of Age and Multiple Vaginal Births on Lower Urinary Tract Structure and Function in Nonhuman Primates

Purpose: The relative roles of urinary sphincter damage, aging, and childbirth in stress urinary incontinence (SUI), have not been established. This study was performed to elucidate the roles of these factors. Methods: The study included: (1) 8 female cynomolgus monkeys (17–19 years of age and 7–8 vaginal births each); (2) six 5-year-old nulliparous monkeys with surgically created chronic urinary

Value of Information analysis accounting for data quality

Structural Health Monitoring (SHM) can provide valuable information for maintenance-related activities and post-disaster emergency management. However, as with any technological system, SHM systems can be susceptible to errors due to malfunctioning. Therefore, it is essential to assess the potential for malfunctions and the associated costs of maintenance and repair when evaluating the long-term b

Bridging the Gaps : Realising Human Diversity in the Built Environment through Universal Design

Denna avhandling undersöker hur mer jämlika och inkluderande livsmiljöer kan uppnås genom att använda Universal Utformning (UU) för att införliva mänsklig mångfald i alla stadier av planering och byggande. Det pågående utanförskapet av personer med funktionsnedsättning från den byggda miljön beror inte på bristande kunskap om hur man kan åtgärda befintliga hinder eller om hur man undviker att skapThis thesis explores how more equal and inclusive living environments can be achieved by using Universal Design (UD) to incorporate human diversity in all stages of planning and construction. The ongoing exclusion of persons with disabilities from the built environment does not result from a lack of knowledge on how to remedy existing obstacles nor of how to avoid creating new ones. Other reasons

SIX1 as a Novel Immunohistochemical Marker in the Differential Diagnosis of Rhabdomyosarcoma

Background: Differential diagnosis of rhabdomyosarcoma (RMS) is challenging. Sineoculis homeobox homolog 1 (SIX1) is an oncogene involved in skeletal muscle differentiation. We compared protein expression patterns of SIX1 in RMS and its most common differential diagnoses. Methods: SIX1 immunohistochemistry in 36 RMS and in 33 tumors from seven differential diagnostic subtypes were evaluated. The f

Impact of landscape configuration and composition on pollinator communities across different European biogeographic regions

Introduction: Heterogeneity in composition and spatial configuration of landscape elements support diversity and abundance of flower-visiting insects, but this is likely dependent on taxonomic group, spatial scale, weather and climatic conditions, and is particularly impacted by agricultural intensification. Here, we analyzed the impacts of both aspects of landscape heterogeneity and the role of c

Sample preparation techniques on dynamic shear rheometer testing : round robin tests on bitumen

Three interlaboratory tests conducted by European laboratories were studied, in which 37 laboratories participated in 2018, rising to 46 in 2019 and 2020. A RTFO-aged neat bitumen 20/30 and PMB 45/80-55 in RTFO-aged and unaged conditions were tested using a DSR at frequency of 1.59 Hz with PP08 and PP25 geometries at temperatures ranging from 10°C to 65°C. To assess variation in numerous areas of

In old men Scheuermann’s disease is not associated with neck or back pain : a Swedish cohort study

Background and purpose — Scheuermann’s disease is characterized by kyphosis and frequently mild back pain. As the level of kyphosis may progress over time, also the level of pain may increase. We evaluated the prevalence of Scheuer-mann’s disease, and their pain, in Swedish elderly men. Patients and methods — The Osteoporotic Fractures in Men (MrOS) Study Sweden (n = 3,014) is a population-based p

Neonatal resuscitation after birth : Swedish midwives’ experiences of and perceptions about separation of mothers and their newborn babies

INTRODUCTION This study aimed to investigate midwives’ experiences of and perceptions about mother–baby separation during resuscitation of the baby following birth. METHODS A qualitative study was conducted using an author-designed questionnaire. Fifty-four midwives from two Swedish birth units with different working methods regarding neonatal resuscitation – at the mother’s bedside in the birth r

Galectin-3 shapes toxic alpha-synuclein strains in Parkinson’s disease

Parkinson’s Disease (PD) is a neurodegenerative and progressive disorder characterised by intracytoplasmic inclusions called Lewy bodies (LB) and degeneration of dopaminergic neurons in the substantia nigra (SN). Aggregated α-synuclein (αSYN) is known to be the main component of the LB. It has also been reported to interact with several proteins and organelles. Galectin-3 (GAL3) is known to have a
