Molecular dynamic simulation of nanosized single-crystal copper beams loaded in tension at different strain rates until necking has been performed for two different crystallographic orientations, the [100]- and the [110]-orientations. The molecular dynamics freeware code LAMMPS was employed for the simulations. It was found that, at low enough strain rates, single necking was obtained for both cry

Wildfires are an important component of terrestrial ecosystem ecology but also a major natural hazard to societies, and their frequency and spatial distribution must be better understood. At a given location, risk from wildfire is associated with the annual fraction of burned area, which is expected to increase in response to climate warming. Until recently, however, only a few global studies of f

Faster bacterial biomass turnover is expected in water compared to soil, which would result in more rapid community adaption to changing environmental conditions, including temperature. Bacterial community adaptation for growth is therefore predicted to have larger seasonal amplitudes in lakes than in soil. To test this prediction, we compared the seasonal variation in temperature adaptation of ba

Aim To explore whether the acute 30-day burden of COVID-19 on health care use has changed from February 2020 to February 2022. Methods In all Norwegians (N = 493 520) who tested positive for SARS-CoV-2 in four pandemic waves (February 26th, 2020 –February 16th, 2021 (1st wave dominated by the Wuhan strain), February 17th–July 10th, 2021 (2nd wave dominated by the Alpha variant), July 11th–December

Context. Occultations are windows of opportunity to indirectly peek into the dayside atmosphere of exoplanets. High-precision transit events provide information on the spin-orbit alignment of exoplanets around fast-rotating hosts. Aims. We aim to precisely measure the planetary radius and geometric albedo of the ultra-hot Jupiter (UHJ) KELT-20 b along with the spin-orbit alignment of the system. M

Bidirectional Low Temperature Networks (BLTNs) are an innovative technology of district heating and cooling systems. Because of their intrinsic feature of supplying simultaneous heating and cooling either directly from an energy source/sink or through distributed heat pumps and chillers, circulation pumps installed at each building extract water from the network and a distinct pressure cone is sub

BACKGROUND: Whereas outdoor temperature is linked to both mortality and hydration status, the hormone vasopressin, measured through the surrogate copeptin, is a marker of cardiometabolic risk and hydration. We recently showed that copeptin has a seasonal pattern with higher plasma concentration in winter. Here, we aimed to investigate the association between outdoor temperature and copeptin.METHOD

Background: Although glomerular diseases are the third most frequent cause of end-stage kidney disease worldwide, little is known about their long-term outcomes. Methods: In patients with chronic kidney disease (CKD) stage 3–5 enrolled in the Swedish Renal Registry, we compared risks of hospitalization, kidney replacement therapy (KRT), major cardiovascular events (MACE), and death of the four mos

Idag har stora delar av världens befolkning tillgång till internet och många äger smarta telefoner och datorer. Den tekniska och teknologiska utvecklingen har skapat snabb och enkel tillgång till fakta, skapat möjligheter för människor att hålla kontakten med varandra på distans, skapat nya jobb och förenklat spridningen av information. I takt med utvecklingen har även användningen av sociala medi

Syfte: Syftet med studien är att identifiera vad som definierar ett framgångsrikt byggprojekt och vilka framgångsfaktorerna är för att säkerställa att projektet enligt beställaren blir framgångsrikt. Vidare är syftet att undersöka hur kravställningen i de administrativa föreskrifterna påverkar ett projekts framgång. Frågeställningar: • Hur definierar beställaren ett framgångsrikt projekt? • Vilka

Sysav tar emot och förbränner brännbart avfall i ett avfallskraftvärmeverk. Vid förbränningen bildas rökgaser som bland annat innehåller svaveloxid. Rökgaserna behöver gå igenom en avsvavlingsprocess eftersom svaveloxid utgör en stor hälsofara på grund av sin toxicitet. Reningsprocessen för rökgaserna består av två skrubbar. I första skrubbern tvättas rökgaserna med vatten och liten mängs kalkslu

The expansion of Chinese media’s global influence has attracted many attentions around the world. When scholars focus on describing how the state-owned media extend beyond borders to reach audience around the globe, the long-existed Chinese diasporic media overseas are lack of discussion. How have they performed and shaped the imagination in-between China, host societies and transnational space? I

Ur ett folkrättsligt perspektiv har EU en säregen karaktär, som gör att Unionen skiljer sig från andra internationella organisationer. Framför allt har EU åstadkommit en höggradig autonomi från såväl det internationella samfundet som medlemsstaternas nationella rättssystem. I doktrinen har anförts att detta skapar ett ”komplext triangulärt förhållande” mellan nationell rätt, EU-rätt och folkrätt. From an international legal perspective, the EU has a special character which makes it different from other international organizations. Most notably, the EU has a high degree of autonomy from both international law and the member states’ domestic legal systems. In legal doctrine, it has been suggested that this creates a “complex triangular relationship” between domestic law, EU law and the inter

In this thesis, a new bridge type is proposed. It is a steel bridge with a slab of cross-laminated timber elements. The bridge is intended for road traffic, and it has a span length of 26 m. It aims to be competitive when a short construction time is important. Long construction time could be a critical issue when launching a bridge over a railway where disruption of traffic flow is associated wit

The growth in Scania is expected to increase by developing Scania’s polycentric structure and create regional expansion. This regional expansion will be developed partly by investments in infrastructure, which are expected to generate better accessibility. The aim of this essay is to investigate a specific train investment in north-eastern Scania, Pågatåg Nordost, and its impacts on development an

Gas cooling is a technique used within the fire service to reduce the risks of the hot gaseous layer and create a better visibility. It is achieved by applying water into the gaseous layer. Successfully performing or implementing this technique is something that has not yet been accomplished in every brigade. This work has been focused on different parameters that affect gas cooling and is studie
