The Dahl friction model is a simple dynamic model for friction obtained by adding dynamics to the stress strain curve. The model captures many aspects of friction and has been used for simulation for a long time. A drawback with the model is that it does not display the stick-slip effect. The LuGre friction model extends the Dahl model to capture the stick-slip motion but is does not capture the f

Recent efforts in engineering metals with high structural efficiency have resulted in developing a new category of artificial materials with heterogeneous microstructures architected across multiple scales. In this critical assessment, a relatively new concept of heterogeneous bimodal harmonic-structure (bHS) materials is introduced and analysed. It is shown that the bHS concept is applicable to a

The aim of this study was to investigate how solar drying setup and choice of juice pretreatment determine the microbiological quality in a fruit juice concentration process called solar assisted pervaporation (SAP). With this process, hygienic membrane pouches and solar energy are used to concentrate and preserve fruit juices. In this study, citrus (tangerine) marmalades were produced with SAP me

The mutualistic symbiosis between forest trees and ectomycorrhizal fungi (EMF) is among the most ubiquitous and successful interactions in terrestrial ecosystems. Specific species of EMF are known to colonize specific tree species, benefitting from their carbon source, and in turn, improving their access to soil water and nutrients. EMF also form extensive mycelial networks that can link multiple

Ossifying fibromyxoid tumor (OFMT) is a soft tissue tumor frequently displaying gene fusions, most of which affect the PHF1 gene. PHF1 encodes plant homeodomain finger protein 1, which is involved in various processes regulating gene transcription, including those orchestrated by the polycomb repressor complex 2. Here, a series of 37 OFMTs, including 18 typical, 9 atypical, and 10 malignant varian

Young adults experiencing mental health problems often need both individual support and educational accommodations to successfully complete their studies. Recent research also points to the need for career-related, educational services in a labor market that increasingly demands formal education or training. The aim of this study was to investigate the development of supported education services i

Aims: The aim of this study was to estimate the healthcare costs and productivity losses associated with county-based home-care services (HCS) for sick children. Methods: In this observational follow-up study, a combination of hospital care and HCS was compared to estimated alternative care solely at the hospital. Data on one year of healthcare utilisation for 32 children, supplied by the hospital

Children at increased genetic risk for type 1 diabetes (T1D) after environmental exposures may develop pancreatic islet autoantibodies (IA) at a very young age. Metabolic profile changes over time may imply responses to exposures and signal development of the first IA. Our present research in The Environmental Determinants of Diabetes in the Young (TEDDY) study aimed to identify metabolome-wide si

The question of the degree to which participation by civil society contributes to environmental decisions in post-conflict societies has received little attention. This study sheds light on the extent to which degrees of participation contribute to environmental decision-making in the Puntland State of Somalia using questionnaire surveys. We found that active participation has the highest contribu

Background: Patients with inflammatory bowel disease (IBD) often develop alterations in body composition in terms of their proportions of lean mass and fat mass, as well as reduced bone mineral density (BMD). However, there are limited data on the skeletal muscle index (SMI) and percentage fat (fat %) for young adults with childhood-onset IBD. Our aim was to investigate the body compositions of th

In the present paper, linear substructures with nonlinearities localized at their interfaces, such as the joints in a beam structure, are studied. By subdivision of the total structure into substructures, reduced subsystems are obtained by component mode synthesis. Nonlinear elements are introduced at supports or between substructures. A numerical example is presented where a beam subjected to bla

BACKGROUND: Physical activity might reduce the risk of developing dementia. However, it is still unclear whether the protective effect differs depending on the subtype of dementia. We aimed to investigate if midlife physical activity affects the development of vascular dementia (VaD) and Alzheimer's disease (AD) differently in two large study populations with different designs.METHODS: Using a pro

On the morning of the 8th of April 2013, the world woke up to Abu Bakr Al- Baghdadi, the leader of what was called the Islamic State in Iraq or ISI, announcing the expansion of his group from Iraq into Syria. Al-Baghdadi also announced the merger of ISI and Jabhat al-Nusra (JN) into a new group called the Islamic State in Iraq and al-Sham or ISIS. Only one day after the announcement, JN released a

In this conceptual paper theory of infrastructure is combined with one of situated learning, with a focus on search and search engines. The aim of the paper is to make a theoretical contribution to the information literacy research field by discussing theoretical contradictions as well as strengths when combining the two theoretical perspectives. Search engines and their use are part of the contem
