In this paper the mechanical response of single-crystal nano-sized Cu beams of different sizes, loaded in displacement controlled tension under constant strain rate is investigated through 3D molecular dynamic simulations using the free-ware LAMMPS. The effects from pure geometric scaling are determined for two different crystallographic orientations of the lattice. Stress–strain curves were recor

Constraints on the composition of the depleted mantle Sm–Nd and Lu–Hf crust formation ages have a long history of scientific debate. When calculating mantle extraction ages, and constructing crustal growth models, a linear evolution of incompatible trace elements in a depleted mantle since > 4 Ga is routinely used. Mantle depletion however varies regionally and over time and subduction of sediment

Objective:We explore whether standardisation in health care based on evidence on group level and a public health perspective is in conflict with responsiveness towards individual patient’s expectations in Swedish primary care.Methods:Using regression analysis, we study the association between patient views about providers’ responsiveness and indicators reflecting provider’s adherence to evidence-b

This article investigates the cross-linguistic comparability of the newly developed lexical assessment tool Cross-linguistic Lexical Tasks (LITMUS-CLT). LITMUS-CLT is a part the Language Impairment Testing in Multilingual Settings (LITMUS) battery (Armon-Lotem, de Jong & Meir, 2015). Here we analyse results on receptive and expressive word knowledge tasks for nouns and verbs across 17 language

Svensk hälso- och sjukvård har i ett historiskt perspektiv dominerats av investeringar i specialistvård och sjukhus. Även om intresset för primärvården har ökat kvarstår många frågor om hur man bäst organiserar verksamheten och vilken betydelse primärvården har för hälso- och sjukvårdens samlade kvalitet och effektivitet. Flera internationella bedömningar pekar mot att det behövs mera grundläggandSvensk hälso- och sjukvård har i ett historiskt perspektiv dominerats av investeringar i specialistvård och sjukhus.

The last decade established that the dynamic properties of the phosphoproteome are central to function and its modulation. The temporal dimension of phosphorylation effects remains nonetheless poorly understood, particularly for intrinsically disordered proteins. Osteopontin, selected for this study due to its key role in biomineralization, is expressed in many species and tissues to play a range

Th2 cytokines like interleukin-4, -5, and -13 are regarded as important drivers of the immunopathology underlying allergic rhinitis (AR) and asthma. The present study explores the capacity of pentosan polysulfate sodium (PPS), a semi-synthetic heparin-like macromolecular carbohydrate, to bind Th2 cytokines and exert biological neutralization in vitro, as well as anti-inflammatory actions in vivo.

In this chapter, we focus on the social integration of young immigrants in Sweden who themselves and/or one or both of their parents came from Iran or former Yugoslavia. In particular, we look at the share of alters in their core networks who are of the same parental national origin and how this has changed within a period of four years. To explain network changes, we consider the parental nationa

Aims. We investigated the relationship between circulating amino acid levels and obesity; to what extent weight loss followed by weight maintenance can correct amino acid abnormalities; and whether amino acids are related to weight loss. Methods. Amino acids associated with waist circumference (WC) and BMI were studied in 804 participants from the Malmö Diet and Cancer Cardiovascular Cohort (MDC-C

BACKGROUND: Patients with chronic kidney disease (CKD) experience high rates of atherosclerotic cardiovascular disease and death that are not fully explained by traditional risk factors. In animal studies, defective cellular cholesterol efflux pathways which are mediated by the ATP binding cassette transporters ABCA1 and ABCG1 are associated with accelerated atherosclerosis. We hypothesized that c

Studies of societal exergy use have the common aim of tracing the flow of exergy along society, and are used to gain insights into the efficiency of energy use and linkages to economic growth. However, their methodological approaches vary greatly, with significant impacts on results. Therefore, we make a review of past studies to identify, synthesize and discuss methodological differences, to cont

Den rödgröna regeringen bör leva upp till tidigare löften om att erkänna folkmordet på armenier, assyrier och pontiska greker. Fler undersökningar är inget annat än en undanflykt, skriver doktoranden Vahagn Avedian och forskaren Svante Lundgren.

Personuppgifter som betalningsmedelDen här rapporten visar hur konsumenternas data kommit att få ett centralt värde i den digitala ekonomin. Förändringen väcker frågor om hur väl konsumentskyddet därmed står sig i förhållande till detta. Studien beskriver och analyserar de konsumentrelaterade utmaningar som den växande användningen av personuppgifter som en form av betalningsmedel medför. I studie

We study the connections between firm risk and the CEO’s personal wealth characteristics, using a unique dataset on CEO wealth and its components. Consistent with decreasing absolute risk aversion, we find that wealthier CEOs are associated with higher risk firms. Riskier firms tend to have CEOs whose wealth is more independent of the firm. We also find that CEOs with high personal portfolio betasWe study the connections between firm risk and the CEO’s personal wealth characteristics, using a unique dataset on CEO wealth and its components.

We study upscaling of gas high harmonic generation, to make efficient use of the ever increasing laser pulse powers. Loose focusing geometries optimizing phasematching are investigated and compared in HHG efficiency to shorter focusing arrangements.

Extrapolating nonlinear phenomena, such as filamentation, to new parameters as e.g. to higher pulse energy is often challenging. We here present a general scaling model for nonlinear light-matter interactions in gases and proof it experimentally.

The heat recovery system for ventilation is of major importance when low energy buildings are built. One alternative to the mechanical ventilation systems with heat recovery is to use a brine based run-around system that allows for heat recovery in for instance hybrid ventilated buildings. This type of heat recovery system has the potential to lower the need for electricity for the fans.
