Accurate solution-adaptive finite difference schemes for coarse and fine grids

We introduce solution dependent finite difference stencils whose coefficients adapt to the current numerical solution by minimizing the truncation error in the least squares sense. The resulting scheme has the resolution capacity of dispersion relation preserving difference stencils in under-resolved domains, together with the high order convergence rate of conventional central difference methods

Low antibiotic resistance rates in Staphylococcus aureus, Escherichia coli and Klebsiella spp but not in Enterobacter spp and Pseudomonas aeruginosa : A prospective observational study in 14 Swedish ICUs over a 5-year period

Background: Intensive care units (ICUs) are hot zones for emergence and spread of antibiotic resistance because of frequent invasive procedures, antibiotic usage and transmission of bacteria. We report prospective data on antibiotic use and bacterial resistance from 14 academic and non-academic ICUs, participating in the ICU-STRAMA programme 1999-2003. Methods: The quantity of antibiotics delivere

Assessment of Metal Cutting Tools using Cost Performance Ratio and Tool Life Analyses

Critical raw materials (CRM) are extensively used in tools for metal cutting, such as in cemented carbide tools (cobalt and tungsten), because they provide desired characteristics of high fracture toughness and wear resistance. Both academia and industry are examining CRM-free material alternatives, such as tools based on polycrystalline diamond (PCD) or ceramic materials. These materials are gene

Yttrande över remissen: En ny Riksbankslag (SOU 2019:46)

Lunds universitet har uppmanats att ge synpunkter på rubricerad remiss. Universitetet lämnar här följande kommentarer vilka har utarbetats vid Ekonomihögskolan vid Lunds universitet av docent Fredrik N G Andersson och professor emeritus Lars Jonung. Inflationsmålet infördes för över 25 år sedan. Villkoren för att bedriva penningpolitik har förändrats på ett omvälvande sätt under detta kvartssekel.

Endogenous and Exogenous Drivers of Oxidative Stress and Inflammation in Preeclampsia

Preeclampsia (PE), is a pregnancy related condition afflicting 3-8% of all pregnancies and a main cause of maternal and infant morbidity and mortality. It is thought to originate from a malfunctioning placental that eventually leads to damage to the maternal endothelium, which in turn gives rise to hypertension and organ dysfunction. Oxidative stress holds a central role in the development, progre

Smartphones and ’planned serendipity’: using the Experience Sampling Method to understand tourism information behaviour in situ

Within the field of tourism information search behaviour, this research aims at exploring the proposed concept of ‘planned serendipity’ and its connection with smartphone use for tourism information search. Although studies on smartphone and tourism have flourished in the past few years, research on information needs and how these needs exist in relation to smartphones is lacking. Moreover, there

The Challenges of Experience Sampling Method in a Qualitative Study on Tourist Information Behaviour on Smartphones

Background of the study One of the main challenges in tourism research is to find effective methodologies to capture the salient moments that make a tourist experience memorable (Cary, 2004; Tussyadiah, 2014). A gap exists between the tourist experience – which happens at a destination, during the time of the trip – and the recollection of it during the study – which often happens days, weeks or m

Soil moisture and hydrology projections of the permafrost region-a model intercomparison

This study investigates and compares soil moisture and hydrology projections of broadly used land models with permafrost processes and highlights the causes and impacts of permafrost zone soil moisture projections. Climate models project warmer temperatures and increases in precipitation (P) which will intensify evapotranspiration (ET) and runoff in land models. However, this study shows that most

WNT5A-induced activation of the protein kinase C substrate MARCKS is required for melanoma cell invasion

WNT5A is a well-known mediator of melanoma cell invasion and metastasis via its ability to activate protein kinase C (PKC), which is monitored by phosphorylation of the endogenous PKC substrate myristoylated alanine-rich c-kinase substrate (MARCKS). However, a possible direct contribution of MARCKS in WNT5A-mediated melanoma cell invasion has not been investigated. Analyses of melanoma patient dat

Degradation of Alzheimer's amyloid fibrils by microglia requires delivery of CIC-7 to lysosomes

Incomplete lysosomal acidification in microglia inhibits the degradation of fibrillar forms of Alzheimer's amyloid β peptide (fAβ). Here we show that in primary microglia a chloride transporter, ClC-7, is not delivered efficiently to lysosomes, causing incomplete lysosomal acidification. ClC-7 protein is synthesized by microglia but it is mistargeted and appears to be degraded by an endoplasmic re
