Contesting aeromobility, constructing alternatives: the prefigurative politics of staying on the ground

The concept of prefiguration has gained attention within environmental politics as a way to describe how everyday activism can enable transformation of unsustainable consumption practices, particularly around material necessities. Drawing on the case of Sweden’s flight-free movement, this article extends the research on prefigurative environmentalism to activism aimed at changing non-essential, ye

Reference ranges for ambulatory heart rate measurements in a middle-aged population

BACKGROUND: Elevated heart rate (HR) predicts cardiovascular disease and mortality, but there are no established normal limits for ambulatory HR. We used data from the Swedish CArdioPulmonary Imaging Study to determine reference ranges for ambulatory HR in a middle-aged population. We also studied clinical correlates of ambulatory HR.METHODS: A 24-hour ECG was registered in 5809 atrial fibrillatio

The effect of axial length on pseudophakic retinal detachment

Abstract Purpose The purpose of the study was to analyse the surgical management and outcome regarding axial length in the population affected by pseudophakic retinal detachment (PRD) 2015?2020. Method The patients included were from an observational cohort study of patients undergoing cataract surgery in the region of Skåne during 2015?2017. Data were retrieved from the Swedish National Cataract Purpose The purpose of the study was to analyse the surgical management and outcome regarding axial length in the population affected by pseudophakic retinal detachment (PRD) 2015-2020.

Demineralized allogeneic bone matrix for cartilage repair

We tested the chondrogenic potential of demineralized allogeneic bone matrix (DABM) in the repair of osteochondral defects. In 42 adult rabbits, a 5-mm2 or 15-mm2 defect was created bilaterally in the intercondylar groove of distal femur. DABM was inserted directly in 37 defects, whereas in 35 it was inserted after previous placement in muscle for 4, 16, or 19 days. Another 12 defects were left em

The occurrence of neuropeptides at different stages of DBM-induced heterotopic bone formation

In developing heterotopic bone in the rat, induced by allogeneic bone matrix, we immunohistochemically detected nerves containing substance P (SP), calcitonin gene-related peptide (CGRP), neuropeptide Y (NPY), vasoactive intestinal polypeptide (VIP) and tyrosine hydroxylase (TH). After 10 days they were dicernible amidst differentiating chondroblastoid cells in fibrous tissue around and within the

Neutron imaging of exchange flow between biopore and matrix for Bt versus C horizons

The surface coating of biopores plays a pivotal role in mediating mass exchange between the biopore and the soil matrix, ultimately governing preferential flow in structured soils. However, quantitative experiments of the flow exchange dynamics in the soil around an earthworm burrow (drilosphere) are limited. Here, we developed an experimental setup to mimic preferential flow within a biopore whil

Analysis of column reactor results with organic decay by native organic microbiota and varying permeability

Field bio-remediation techniques (FBRT) can be a low cost method to avoid the removal of top layers of soil which are rich in organic matter and bio diversity. The use of native microorganisms in FBRT is preferable because non-indigenous species can transfer their genetic material to the environment with negative impacts on the local ecological equilibrium. Petroleum Produced Water (PPW) is an imp

Integrationskrav i domstol : En studie av hur svenska migrationsdomstolar förhåller sig till nationella politiska ambitioner och övernationella rättskällor

Civic integration is an essential part of contemporary migration control regimes. This thesis examines what happens when civic integration policy enters domestic courts, by focusing on how Sweden’s migration courts (which are part of the administrative courts) apply the income and housing requirements for family reunification.The thesis revolves around a common discussion in the legal literature,

Transformative Climate Resilience Education for Children and Youth: From Climate Anxiety to Resilience, Creativity and Regeneration, Literature review conducted for the ERASMUS+ Project 2023-1-SE01-KA220-SCH-000158705

This report has been written as part of the ERASMUS+ project CLARITY. The aim of CLARITY is to enhance educators' skills for nurturing resilience and reducing climate anxiety of learners through trauma-informed and creative approaches that link inner and outer dimensions of change. Sustainability and climate education tend to focus on environmental facts, whilst little room is given to the human d

Rötter i rörelse. Kulturarv på trädgårdens marknader

Den här boken handlar om hur växter, trädgårdar och trädgårdshantverk i vår tid görs till kulturarv och tar plats på marknader av olika slag. Här pågår ett ständigt prövande av vad som i olika avseenden betraktas som vitalt nog, appellerar till aktuella trender, har tillräckligt intresseväckande namn eller på annat sätt är gångbart.Utifrån en rad exempel på kulturarvsträdgårdar och kulturarvsväxte

High incidence of kidney stones in Icelandic children

All children less than 18 years of age who were diagnosed with a first episode of kidney stones at pediatric referral centers in Iceland during the years 1995-2000 were studied retrospectively. The diagnosis was based on clinical features and results of imaging studies. Patients were invited for evaluation at the end of the study period. Twenty-six patients (15 females, 11 males), median age 9.4 (

Severe Lung Dysfunction and Pulmonary Blood Flow during Extracorporeal Membrane Oxygenation

Background: Extracorporeal membrane oxygenation (ECMO) is indicated for patients with severe respiratory and/or circulatory failure. The standard technique to visualize the extent of pulmonary damage during ECMO is computed tomography (CT). Purpose: This single-center, retrospective study investigated whether pulmonary blood flow (PBF) measured with echocardiography can assist in assessing the ext

xrdPlanner : exploring area detector geometries for powder diffraction and total scattering experiments

xrdPlanner is a software package designed to aid in the planning and preparation of powder X-ray diffraction and total scattering beam times at synchrotron facilities. Many modern beamlines provide a flexible experimental setup and may have several different detectors available. In combination with a range of available X-ray energies, it often makes it difficult for the user to explore the availab

Recurrence, fidelity and proximity to previously visited sites throughout the annual cycle in a trans-Saharan migrant, the common cuckoo

Most migratory birds return every year to the same breeding sites and some species show a similarly high fidelity to wintering grounds as well. Fidelity to stopover sites during migration has been much less studied and is usually found to be lower. Here, we investigate site fidelity and distance to previously visited sites throughout the annual cycle in the common cuckoo, a nocturnal trans-Saharan

Previous SARS-CoV-2 infections and their impact on the protection from reinfection during the Omicron BA.5 wave – a nested case-control study among vaccinated adults in Sweden

Objectives: We evaluated the protection afforded by SARS-CoV-2 infection-induced immunity against reinfection among working-age vaccinated individuals during a calendar period from June to December 2022 when Omicron BA.5 was the dominating subvariant in Scania County, Sweden. Methods: The study cohort (n = 71,592) mainly consisted of health care workers. We analyzed 4144 infected cases during the

Sex differences in outcomes after revascularization for acute lower limb ischemia : Propensity score adjusted analysis

Background: Previous reports have suggested higher rates of mortality and amputation for female patients in acute lower limb ischemia (ALI). The aims of the present study were to investigate if there is a difference in mortality, amputation, and fasciotomy between the sexes. Methods: A retrospective cohort study of consecutive patients undergoing index revascularization for ALI between 2001 and 20
