Modelling of Stiffness and Hygroexpansion of Wood Fibre Composites

Paper 1The field of research involving the analytical modelling of the stiff ness and hygroexpansion of composite material is reviewed. This paper can be regarded as an introduction to the area of the mechanics of composite materials in general and to wood bre composites in particular. The most important models, such as the Reuss and Voigt bounds and the Halpin-Tsai, are described, along with theiPaper 1The eld of research involving the analytical modelling of the stiff ness and hygroexpansion of composite material is reviewed.

(Mis)alignment in returns management : integration of process, policy and business intent

Purpose: The purpose of this research is to shed light on the formulation of returns management strategies and identify key returns management components to be considered when developing effective returns management strategies.Design/methodology/approach: A multiple confirmatory case study of six retailers operating in online commerce was carried out. Interviews with 15 managers formed the primary

Uncovering new families and folds in the natural protein universe

We are now entering a new era in protein sequence and structure annotation, with hundreds of millions of predicted protein structures made available through the AlphaFold database1. These models cover nearly all proteins that are known, including those challenging to annotate for function or putative biological role using standard homology-based approaches. In this study, we examine the extent to

A nationwide case-control study on cardiovascular and respiratory-related disorders in patients with gambling disorder in Sweden

Objectives: We aimed to examine potential relationships and gender differences between cardiovascular disease (CVD), diabetes, obesity, respiratory-related disorders, and gambling disorder (GD). We hypothesized that (1) GD patients would be more likely than controls to have CVD, diabetes, obesity, and respiratory-related diseases; and (2) females with GD would be more likely than men with GD to ha

Anti-Compton shield for Compex germanium detector modules

A bismuth-germanate (BGO) anti-Compton shield (ACS) for Compex germanium detector modules was designed, built, and characterised. BGO performance was evaluated for light output and energy resolution. The response of the ACS shield and its impact on germanium detector spectra was measured for standard 60Co, 133Ba, and 137Cs sources. The results were compared to comprehensive Geant4 simulations. The

CRP in Outpatients with Inflammatory Bowel Disease Is Linked to the Blood Microbiota

The circulation is a closed system that has been assumed to be free from bacteria, but evidence for the existence of a low-density blood microbiota is accumulating. The present study aimed to map the blood microbiota of outpatients with Crohn’s disease (CD) or with ulcerative colitis (UC) by 16S metagenomics. A diverse microbiota was observed in the blood samples. Regardless of the type of disease

Status and Criminal Liability of Civil Servants in Modern Public Administration : A Comparative Study of Denmark, Finland, and Sweden

Accountability is a central topic in administrative law. To hold persons and institutions executing public power legally accountable in various ways is linked to ideas of good governance, democracy, legitimacy, and the rule of law. In the last decades, established structures for accountability in the public sector have been challenged through processes of privatization of public services, digitali

Race/Ethnicity and Gender Representation in Hematology and Oncology Editorial Boards : What is the State of Diversity?

Introduction: Women and underrepresented groups in medicine hold few academic leadership positions in the field of hematology/oncology. In this study, we assessed gender and race/ethnicity representation in editorial board positions in hematology/oncology journals. Materials and Methods: Editorial leadership board members from 60 major journals in hematology and oncology were reviewed; 54 journals

Exposure to hand-held vibrating tools and biomarkers of nerve injury in plasma : A population-based, observational study

Objectives To analyse potential biomarkers for vibration-induced nerve damage in a population-based, observational study. Design Prospective cohort study. Setting Malmö Diet Cancer Study (MDCS), Malmö, Sweden. Participants In a subcohort of 3898 individuals (recruited 1991-1996) from MDCS (baseline examination in 28 449 individuals; collection of fasting blood samples in a cardiovascular subcohort

New insights into the disulfide stress response by the Bacillus subtilis Spx system at a single-cell level

Spx is a global transcriptional regulator that orchestrates the Bacillus subtilis response to disulfide stress. The YjbH (SpxH) protein adapts Spx for ClpXP-mediated degradation, playing a critical role in the regulation of the cellular Spx levels. Upon stress, YjbH forms aggregates by a yet unknown mechanism, resulting in increased Spx levels due to reduced proteolysis. Here, we studied how indiv

Growing Inwards : Densification and Ecosystem Services in Comprehensive Plans from Three Municipalities in Southern Sweden

This article analyses how urban densification, primarily in relation to ecosystem services, is addressed in comprehensive plans from three cities in southernmost Sweden: Malmö, Lund and Helsingborg. The aim was to investigate and problematise how the comprehensive plans articulate and negotiate how to build dense cities while preserving and enhancing ecosystem services. A qualitative content analy

Efficient buckling constrained topology optimization using reduced order modeling

We present an efficient computational approach to continuum topology optimization with linearized buckling constraints, using Reduced Order Models (ROM). A reanalysis technique is employed to generate basis vectors that subsequently are used to significantly reduce the size of the generalized eigenvalue problems. We demonstrate the efficacy of this approach by optimizing for stiffness with bucklin

Feminist LCAs : Finding leverage points for wellbeing within planetary boundaries

Life Cycle Assessment (LCA) studies are valuable tools for identifying high impact processes and redesigning supply chains. However, LCAs have limits, in the sense that they offer insight into relative sustainability and don't question whether a product, or its use, is sustainable in absolute terms. In this intentionally provocative paper, you join Emma, a fictional average American 15-year-old, a

Hypothermia versus normothermia after out-of-hospital cardiac arrest; the effect on post-intervention serum concentrations of sedatives and analgesics and time to awakening

Background: This study investigated the association of two levels of targeted temperature management (TTM) after out-of-hospital cardiac arrest (OHCA) with administered doses of sedative and analgesic drugs, serum concentrations, and the effect on time to awakening. Methods: This substudy of the TTM2-trial was conducted at three centers in Sweden, with patients randomized to either hypothermia or
