CBN-based cutting tools with niobium compounds as a binder phase

cBN-based materials are well known for their high chemical inertness and high performance. The variation of binder phase type and amount enable improvement of performance even more. Comprehensive investigation of the influence of type of niobium compound (NbC and NbN) as a binder phase for cBN-based materials were done. Samples were prepared by high pressure high temperature (HPHT) sintering under

Effect of inlet chamber design and operation conditions on laminar drop deformation in a production-scale high-pressure homogenizer—A hydrodynamic investigation

Due to their wide utilization and low thermodynamic efficiency, there is a large interest in designing more efficient high-pressure homogenizer valves. Drop breakup in these devices is by turbulent interaction downstream of the gap exit. However, recent investigations in scaled systems suggest that the drops can be ‘primed’ for breakup by elongation upstream of the gap entrance. This study uses hy

Swedish midwives’ experiences of collegial midwifery assistance during the second stage of labour: A qualitative study

BackgroundThere has been an increased focus on clinical practice that may reduce severe perineal trauma due to awareness of the associated morbidity. Knowledge regarding the best practice to reduce these injuries is limited. Collegial midwifery assistance during the second stage of labour that involves an additional midwife being present has recently been implemented into many Swedish birth units

Multiscale Structural Elucidation of Peptide Nanotubes by X-Ray Scattering Methods

This mini-review presents the structural investigations of the self-assembled peptide nanotubes using X-ray scattering techniques. As compared to electron microscopy, scattering methods enable studies of nanotubes in solution under the appropriate physicochemical conditions and probe their formation mechanism. In addition, a combination of X-ray scattering methods allow the elucidation of structur

The status of homelessness: Access to housing for asylum-seeking migrants as an instrument of migration control in Italy and Sweden

Homelessness and other forms of destitution among asylum-seeking migrants are currently on the rise across Europe, as migrants’ access to social rights, including housing, has been restricted through repressive migration policies, fuelled by the welfare nationalism and chauvinism that surge among European states. This article explores the largely overlooked homelessness experienced by migrants seeHomelessness and other forms of destitution among asylum-seeking migrants are currently on the rise across Europe, as migrants’ access to social rights, including housing, has been restricted through repressive migration policies, fuelled by the welfare nationalism and chauvinism that surge among European states.

Association of autoimmune diseases with cardiomyopathy : A nationwide follow-up study from Sweden

Aims: Certain autoimmune diseases (ADs), such as Crohn's disease and celiac diseases, have been linked to acute cardiovascular disorders. We examined whether there is an association between 43 different ADs and risk of subsequent hospitalization and mortality of cardiomyopathy in a nationwide follow-up study in Sweden. Methods and results: All individuals in Sweden hospitalized with a main diagnos

Seasonal patterns in nutrient bioavailability in boreal headwater streams

Changes in nutrient bioavailability due to increased loading of dissolved organic matter (DOM) may impact boreal freshwaters. Yet, the relative bioavailability of carbon (C), nitrogen (N), and phosphorus (P) associated with terrestrial DOM remains poorly understood. We applied short-term bioassays with natural bacterial inocula to determine seasonal variation in bioavailable organic nutrient pools

Brottsförebyggande ungdomsarbete i Malmö och Helsingborg. En utvärdering av Fryshusets preventiva insatser och civilsamhällets roll för unga i riskzonen

Den här rapporten är en utvärdering och analys av Stiftelsens Fryshusets förebyggande ungdomsarbete i Malmö och Helsingborg och bygger till stor del på intervjuer med ungdomar i utsatta områden, samt fältstudier. Rapporten är skriven på uppdrag av Stiftelsen Fryshuset, är finansierad av H.M. Drottning Silvias Stiftelse – Care About the Children, och påbörjades i maj 2021 och avslutades i december

Real-time data processing in the ALICE High Level Trigger at the LHC

At the Large Hadron Collider at CERN in Geneva, Switzerland, atomic nuclei are collided at ultra-relativistic energies. Many final-state particles are produced in each collision and their properties are measured by the ALICE detector. The detector signals induced by the produced particles are digitized leading to data rates that are in excess of 48 GB/s. The ALICE High Level Trigger (HLT) system p

Glucose-lowering action through targeting islet dysfunction in type 2 diabetes : Focus on dipeptidyl peptidase-4 inhibition

Dipeptidyl peptidase-4 (DPP-4) inhibition is a glucose-lowering medication for type 2 diabetes. It works through stimulation of insulin secretion and inhibition of glucagon secretion in a glucose-dependent manner, resulting in lowered fasting and postprandial glycemia with low risk of hypoglycemia. As impaired insulin secretion and augmented glucagon secretion are key factors underlying hyperglyce

Three Agricultural Revolutions

Attempts to imagine a shift beyond capitalism often tend to fixate on the terms of the old socialist calculation debate: plan versus market. At its deepest level, though, capitalism is not fundamentally a matter of the distribution of goods, for underlying this is the possession of land. In thinking about the end of capitalism it is thus useful to return to the question of its origin as the second

Effect of Continuous Positive Airway Pressure on Lipid Profiles in Obstructive Sleep Apnea : A Meta-Analysis

Background: Obstructive sleep apnea (OSA) is associated with dyslipidemia. However, the effects of continuous positive airway pressure (CPAP) treatment on lipid profiles are unclear. Methods: PubMed/Medline, Embase and Cochrane were searched up to July 2021. Randomized controlled trials (RCTs) of CPAP versus controls with ≥4 weeks treatment and reported pre-and post-intervention lipid profiles wer

Air Pollution and Cognitive Impairment across the Life Course in Humans : A Systematic Review with Specific Focus on Income Level of Study Area

Cognitive function is a crucial determinant of human capital. The Lancet Commission (2020) has recognized air pollution as a risk factor for dementia. However, the scientific evidence on the impact of air pollution on cognitive outcomes across the life course and across different income settings, with varying levels of air pollution, needs further exploration. A systematic review was conducted, us

Peak exercise SBP and future risk of cardiovascular disease and mortality

Objectives: This study aimed to evaluate the risk of all-cause mortality and incident cardiovascular disease associated with peak systolic blood pressure (PeakSBP) at clinical exercise testing. Methods: Data from 10096 clinical exercise tests (54% men, age 18—85 years) was cross-linked with outcome data from national registries. PeakSBP was compared with recently published reference percentiles as

Intergenerational care in Sweden : A biographical approach

Practices of care between grandparents, adult children and grandchildren are the hub of intergenerational relationships. To care for an elderly parent, or for a grandchild, is an engagement that can be a necessity coming out of lack of other care providers, or it can be an engagement you voluntarily take upon yourself. It can feel like an obligation, and/or as something you do out of love for your
