Coupled heat, mass and momentum transport in swelling cellulose based materials with application to retorting of paperboard packages

Understanding the complex interplay of mass transport, heat transport and deformation in swelling cellulose based materials is a challenging task. To aid in this endeavour a multiphysics model is developed within the mixture theory framework. The model is macroscopic and accounts for swelling, non-equilibrium mass exchange of water, elastic deformation and multiphase transport phenomena, where non

Det smarta hemmets mundanisering

The smart home around 2020 is based on interconnected software equipped things that through automation are supposed to deliver new pleasures and conveniences. This technological makeover of domestic settings is characterised by consumption of things that are promoted as novel and spectacular. If successful, these things are then gradually transformed into ignored infrastructure, into paraphernalia

Removal of pharmaceutical metabolites in wastewater ozonation including their fate in different post-treatments

Advanced treatment technologies for the removal of pharmaceuticals and other organic micropollutants in WWTPs primarily target the removal of parent compounds. Nevertheless, the removal of metabolites originating from human- or microbial metabolism during biological treatment needs comparable consideration, as some of them might be present in high concentrations and contribute to toxicity. This st

Magnesium/Nano-hydroxyapatite Composite for Bone Reconstruction : The Effect of Processing Method

Nano-ceramic particles can serve as reinforcing agents for metallic materials to improve their mechanical properties. However, it is important to ensure chemical compatibility between the matrix and particles. In the present study, magnesium composites with and without nano-hydroxyapatite (nHA) particles were fabricated for bone reconstruction applications. Two different techniques were used, Conv

A feedforward approach to mid-ranging control

Mid-ranging control is a control strategy that is used when there are more than one manipulated variable available to control a process variable. Mid-ranging control handles the redundancy by coordinating the roles of the different manipulated variables. The most common approach is to introduce valve position controllers (VPC) that control the relations between the manipulated variables. In this p

Mesh bags underestimated arbuscular mycorrhizal abundance but captured fertilization effects in a mesocosm experiment

Aims: Ingrowth bags are widely used to estimate mycorrhizal growth and dynamics. However, it remains unclear to what extent they reflect the surrounding soil, and how this varies with environmental conditions. Methods: We used a fertilization experiment to investigate if carbon-free mesh bags were representative of their surrounding soil. We determined AMF hyphal length density (HLD), phospholipid

Functionalized single-walled carbon-nanotube-blended P3HT-based high performance memory behavior thin-film transistor devices

We report on the fabrication and transport properties of single-walled carbon nanotubes (SWCNT) blended with P3HT (poly 3-hexyl thiophene-2, 5-diyl). The composite is used as a hybrid organic active channel transistor. The performances of the fabricated devices were investigated as a function of the SWCNTs' loads in the composite, and their response evaluated under white light illumination. Our re

Promote social participation among older persons by identifying physical challenges – An important aspect of preventive home visits

Introduction: Social participation can have a positive impact on health; however, physical challenges can be hindrances. During a preventive home visit a health professional (visitor) assesses different aspects of physical, mental and social health. However, there might be a challenge for the visitor to discover the interrelationship between physical factors that hinder social participation. There

Statistical semantics : Methods and applications

This book discusses the application of various statistical methods to texts, rather than numbers, in various fields in behavioral science. It proposes an approach where quantitative methods are applied to data whereas previously such data were analyzed only by qualitative research methods. To emphasize the quantitative aspects of semantics, and the possibilities of conducting scientific interferen

Hygro-thermo-mechanical modeling of partially saturated air-entrained concrete containing dissolved salt and exposed to freeze-thaw cycles

In cold regions, understanding the freeze-thaw behavior of air-entrained concrete is important for designing durable structures and assessing the remaining service life of existing structures. This study presents a hygro-thermo-mechanical multiphase model that describes the cyclic freeze-thaw behavior of partially saturated air-entrained concrete containing dissolved salt. An equilibrium and a non

Taking Seat

The sound work "Taking Seat" by Robert Willim, could be experienced from a specially designed ‘sound bench’ placed outside Skissernas Museum in Lund. Combining manipulations of words and field recordings the work reflects practices of sitting.What are the forces set in motion by sitting? What are the technologies and techniques of sitting?Anthropologists argue that we have been living in The Sitti

A process model for collaboration in circular oriented innovation

Circular oriented innovation commonly requires collaboration. Yet, to date, circular research lacks empirical investigation into collaborative processes. Collaborative processes are, however, highly researched within strategic management literature, thus offering valuable insights. The purpose of this paper is to investigate, identify and order the processes that companies undertake when designing

Payments by modelled results : A novel design for agri-environmental schemes

From a theoretical point of view, result-based agri-environmental payments are clearly preferable to action-based payments. However, they suffer from two major practical disadvantages: costs of measuring the results and payment uncertainty for the participating farmers. In this paper, we propose an alternative design to overcome these two disadvantages by means of modelling (instead of measuring)

Incidence and outcome of myocardial infarction treated with percutaneous coronary intervention during COVID-19 pandemic

Objective Most reports on the declining incidence of myocardial infarction (MI) during the COVID-19 have either been anecdotal, survey results or geographically limited to areas with lockdowns. We examined the incidence of MI during the COVID-19 pandemic in Sweden, which has remained an open society with a different public health approach fighting COVID-19. Methods We assessed the incidence rate (

Do value-attitude-behavior and personality affect sustainability crowdfunding initiatives?

Crowdfunding is an innovative financial measure that is increasingly important in supporting sustainability initiatives. However, little research-based theory has been devoted to crowdfunding in light of the Sustainable Development Goals (SDGs). To bridge this gap, this study utilizes theories of value-attitude-behavior (VAB) model and personality to investigate Korean consumer crowdfunding behavi

Imaging in gynecological disease (20) : clinical and ultrasound characteristics of adnexal torsion

Objectives: To describe the clinical and ultrasound characteristics of adnexal torsion. Methods: This was a retrospective study. From the operative records of the eight participating gynecological ultrasound centers, we identified patients with a surgically confirmed diagnosis of adnexal torsion, defined as surgical evidence of ovarian pedicle, paraovarian cyst and/or Fallopian tube twisted on its
