Identification of elastic/visco-plastic material constants under impact loading

A numerical simulation is performed to identify the material parameters of an elastic/visco-plastic material under tensile impact loading. The identification is based on an inverse analysis using the Kalman filter technique and the finite element method. The input data to the inverse analysis are the time histories of the strains on specimens. The measurement errors can be treated reasonably by thA numerical simulation is performed to identify the material parameters of an elastic/visco-plastic material under tensile impact loading.

Self-Disorders in Asperger Syndrome Compared to Schizotypal Disorder : A Clinical Study

OBJECTIVE: There are historical and theoretical indications of a difference in subjective experience between autism spectrum disorder (ASD) and the schizophrenia spectrum. However, this difference has not been empirically explored. Therefore, to explore potential differences in subjective experience between the 2 spectra, we examined the presence/absence of self-disorders in Asperger syndrome/auti

Evaluation of global simulations of aerosol particle and cloud condensation nuclei number, with implications for cloud droplet formation

A total of 16 global chemistry transport models and general circulation models have participated in this study; 14 models have been evaluated with regard to their ability to reproduce the near-surface observed number concentration of aerosol particles and cloud condensation nuclei (CCN), as well as derived cloud droplet number concentration (CDNC). Model results for the period 2011-2015 are compar

Characterisation of mechanical and thermal properties of tungsten for high power spallation target applications

Inom ett par år kommer det nya materialforskningscentret ESS, The European Spallation Source, att stå färdigbyggt. Det kommer då vara det mest avancerade forskningsinstitutet i sitt slag och leverera upp till 30 gånger fler neutroner än någon annan neutronkälla i världen. En av de viktigaste komponenterna på ESS är det s.k. strålmålet som består av nästan 7000 bitar av det metalliska grundämnet voThe European Spallation Source (ESS), which is currently under construction in Lund, will use pure tungsten as the spallation neutron target. The tungsten will be irradiated by a 2 GeV proton beam, pulsed at a repetition rate of 14 Hz. Each pulse will deposit 357 kJ in the tungsten causing an instantaneous temperature rise of approximately 100 °C, during the 2.86 ms pulse duration. The target is w

Factors Associated With Symptom Relief in End-of-Life Care in Residential Care Homes : A National Register-Based Study

Context: Residential care homes (RCHs) are a common place of death. Previous studies have reported a high prevalence of symptoms such as pain and shortness of breath among residents in the last week of life. Objectives: The aim of the study was to explore the presence of symptoms and symptom relief and identify factors associated with symptom relief of pain, nausea, anxiety, and shortness of breat

A new perspective in the road asset management with the use of advanced monitoring system & BIM

The present paper reports different applications which have a common data source: Automatic Road Analyzer (ARAN) of the Transport Infrastructure Laboratory of the University of Catania. Data surveyed with ARAN were used to develop performance indicators of the road asset. A BIM model makes possible to improve the flexibility in information access and to merge data with the aim to allow a complete

Proteomic profiling of osteoarthritis. A computational approach to biomarker discovery.

Understanding the molecular mechanisms of osteoarthritis (OA) is critical for early diagnosis and effective treatment. OA is a leading cause of disability and poses an increasing burden on healthcare systems, particularly with an aging global population. Despite the potential of proteomics to elucidate the complex biology underlying OA, its application remains limited due to challenges including g

Metabolic engineering of Thermoanaerobacterium AK17 for increased ethanol production in seaweed hydrolysate

Sustainably produced renewable biomass has the potential to replace fossil-based feedstocks, for generation of biobased fuels and chemicals of industrial interest, in biorefineries. In this context, seaweeds contain a large fraction of carbohydrates that are a promising source for enzymatic and/or microbial biorefinery conversions. The thermoanaerobe Thermoanaerobacterium AK17 is a versatile ferme

Randanteckningar om svensk mediepolitik 1920–1970 : Ur temamodellering av 11 000 riksdagsprotokoll

In an explorative manner, this article uses a data-driven digital history set-up to focus on how the Swedish Riksdag, its political parties and parliament members discussed media issues. By distant reading and topic modeling a dataset of more than 11,000 parliamentary minutes – approximately 400 million characters – the article gives a new perspective of Swedish media history in general and nation

Blood-based mitochondrial respiratory chain function in major depression

Mitochondrial dysfunction has been implicated in major depressive disorder (MDD). A measure of mitochondrial respiratory chain (RC) enzymatic activity—the Mitochondrial Health Index (MHI)—has previously been found to correlate with stress and emotional states in caregivers. We here report mitochondrial RC activities, mitochondrial DNA copy number (mtDNAcn), and the composite MHI in unmedicated and

Seasonal dynamics of haemosporidian (Apicomplexa, Haemosporida) parasites in house sparrows Passer domesticus at four European sites : comparison between lineages and the importance of screening methods

Infectious diseases often vary seasonally in a predictable manner, and seasonality may be responsible for geographical differences in prevalence. In temperate regions, vector-borne parasites such as malaria are expected to evolve lower virulence and a time-varying strategy to invest more in transmission when vectors are available. A previous model of seasonal variation of avian malaria described a

A numerical investigation of dimple effects on internal heat transfer enhancement of a double wall cooling structure with jet impingement

Purpose - The dimple is adopted into a double wall cooling structure which is widely used in hot gas components to increase the heat transfer effects with relatively low pressure drop penalty. The purpose of this paper is to study the effect of dimple depth and dimple diameter on the target surface heat transfer and the inlet to outlet friction factor. Design/methodology/approach - The study is ca
