Repeatability of digital image correlation for measurement of surface strains in composite long bones

Digital image correlation (DIC) can measure full-field surface strains during mechanical testing of hard and soft tissues. When compared to traditional methods, such as strain gauges, DIC offers larger validation data (similar to 50,000 points) for, e.g., finite element models. Our main aim was to evaluate the repeatability of surface strain measurements with DIC during compressive testing of comp

The bilayer melting transition in lung surfactant bilayers: the role of cholesterol.

Aqueous di persions of a porcine lung surfactant (PLS) extract with and without cholesterol supplementation were analyzed by X-ray scattering. Lamellar liquid-crystalline and gel-type bilayer phases are formed, as in pure phosphatidylcholine (PC)-cholesterol systems. This PLS extract, developed for clinical applications, has a cholesterol content of less than 1% (w/w). Above the limit of swelling,

Hedging With Heritage: Investigating The Risk-Mitigating Role Of Corporate Brand Heritage

Title: Hedging with Heritage: Investigating the risk-mitigating role of Corporate Brand Heritage Course: BUSN39 - Degree Project in Global Marketing Purpose: This study aims to examine the relationship between corporate brand heritage and their stock price volatility. Methodology: A quantitative approach is employed, using researcher-assigned formative indicators to quantify corporate brand herit

Det handlar inte om att ha råd - Höginkomsttagares konsumtionsmönster i en tid av ekonomisk och social osäkerhet

In times of rising inflation, global unrest and shifting societal values, much of the public and academic focus has been on how economically vulnerable groups adapt their consumption. However, less attention has been paid to high-income earners who are often assumed to remain unaffected by economic fluctuations. This thesis investigates how high-income individuals in Sweden navigate their everyday

First-line Aspiration Thrombectomy with the RED43 Catheter for Acute Ischemic Stroke due to Medium or Distal Vessel Occlusion

PURPOSE: Techniques for endovascular thrombectomy in acute ischemic stroke due to medium or distal vessel occlusions (MDVO) need to be improved, and first-line aspiration is emerging as a promising technique. The objective was to describe first-pass and final reperfusion rates with a triaxial direct aspiration first pass technique (ADAPT) and a novel, quadriaxial technique (QUATTRO-ADAPT) using RE

Tundra landscape heterogeneity, not interannual variability, controls the decadal regional carbon balance in the Western Russian Arctic

Across the Arctic, the net ecosystem carbon (C) balance of tundra ecosystems is highly uncertain due to substantial temporal variability of C fluxes and to landscape heterogeneity. We modeled both carbon dioxide (CO2) and methane (CH4) fluxes for the dominant land cover types in a ~100-km2 sub-Arctic tundra region in northeast European Russia for the period of 2006–2015 using process-based biogeoc

Epigenetic regulatory role of MORC2 in human brain development

Close encounters of the TE kind: molecular consequences of MORC2 mutations Nearly half of our DNA is composed of transposable elements (TEs), sequences that can copy and move around within the genome. When they move, they can disrupt the stability of our genome and cause damage to our cells. In response to that, cells have evolved mechanisms to minimize their movements. One protein that repress

Point-of-care musculoskeletal ultrasound for hemophilic arthropathy : a scoping review of scanning protocols by the Imaging Expert Working Group of the International Prophylaxis Study Group

Background: People with hemophilia (PwH) or von Willebrand disease (VWD) are at risk of joint bleeding, which can lead to hemophilic arthropathy. Point-of-care musculoskeletal ultrasound (POC-MSKUS) is increasingly used to detect joint bleeds, but a comprehensive compilation of available independent scanning protocols and their respective measurement properties is missing. Objectives: This study a

Metabolic syndrome in childhood, adolescent, and young adult cancer survivors: recommendations for surveillance from the International Late Effects of Childhood Cancer Guideline Harmonization Group

Objective: Survivors of childhood, adolescent, and young adult (CAYA) cancer have an increased risk of metabolic syndrome (MetS). MetS describes the clustering of cardiovascular risk factors including overweight or obesity, hypertension, (pre)diabetes, and dyslipidaemia. While associated cardiovascular sequelae can be serious, MetS is preventable, manageable, and potentially reversible with the ap

A comprehensive review of six dietary polyphenols in colorectal cancer : Pharmacokinetics, mechanism and therapeutic potentials

Background Colorectal cancer (CRC) remains a major global health challenge with high morbidity and mortality despite advances in detection and treatment. Dietary polyphenols are secondary metabolites widely found in plant-derived foods and beverages, and have gained attention for their potential in CRC prevention and therapy due to their diverse biological activities. Methods This review synthesiz

"Mellan heder och frihet". En textanalys av självbiografier om unga kvinnors upplevelser av hedersförtryck och deras möte med yrkesverksamma.

This study examines how young women who have lived under honor-based violence and oppression describe their experiences in self-biographical narratives, with particular attention to how gender, family structures, culture, migration, and social position shape their everyday lives and opportunities for self-determination. The empirical material consists of two Swedish self-biographies by Elaf Ali (2

Mitigating dye and organic pollutant-driven surface water pollution using ZnO nanoparticles : a sustainable strategy for climate resilience

Surface water pollution consists of various pollutants like heavy metals (Cu, Cr, Pb, and Ni), metalloids (Se, As, and Ag), and organic pollutants (dyes, antibiotics, pharmaceuticals, pesticides, and phenolic compounds). The escalating issue of water pollution requires innovative solutions for mitigation and climate resilience. Although various advanced techniques are being developed for removing

Infrared thermography is a useful tool in research on thermoregulation and evolution of heat tolerance

Non-invasive methods for measuring thermal tolerance and thermoregulation in large numbers of individuals under natural environmental conditions are useful to understand the capacity of species to adapt to future climate scenarios. Infrared thermography (IRT) is one such tool in research on thermal adaptation, but concerns have been raised about its reliability, specifically the correlation betwee

Associations of Adolescent BMI and Physical Fitness With Cardiovascular Health in Middle Age : A Population-Based Prospective Study of Swedish Men

Introduction: Early-life determinants of middle-age cardiovascular health are poorly understood. This study examines associations of BMI and physical fitness in male adolescents with cardiovascular health measured by the Life's Essential 8 score in middle age. Methods: A population-based cohort study linked BMI and physical fitness from the Swedish Military Conscription Register (men conscripted f
