We consider entropy conservative and dissipative discretizations of nonlinear conservation laws with implicit time discretizations and investigate the influence of iterative methods used to solve the arising nonlinear equations. We show that Newton’s method can turn an entropy dissipative scheme into an anti-dissipative one, even when the iteration error is smaller than the time integration error.

Verken ställdes ut på samlingsutställningen 'Hur går det?' på Keramiskt Center i Höganäs. Verken är en del av forskningsprojektet 'Tångens potentiella mellanrum', inom vilket tångens materialitet undersöker och problematiserar. Verken utforskar mötet mellan uttryck och upplevelser av tången utifrån lera som material.

The electricity prices in Sweden and Europe during 2022 have reached very high levels. The main reason for this being the war in Ukraine, which has led to a decreased availability for gas. During summer, the electricity prices reached extreme levels when meteorological and hydrological factors worsened the situation on the electricity market. The highest daily electricity price on the Nordic marke

Bone mineralization involves a complex orchestration of physico-chemical responses from the organism. Despite extensive studies, the detailed mechanisms of mineralization remain to be elucidated. This study aims to characterize bone mineralization using an in-vivo long bone fracture healing model in the rat. The spatio-temporal distribution of relevant elements was correlated to the deposition and

Börskraschen på Wall Street hösten 1929 är en av alla tiders mest spektakulära ekonomiska händelser. Den är följaktligen flitigt omskriven, naturligt nog mest ur amerikanskt perspektiv. Här ska vi betrakta den ur svenskt perspektiv. Hur reagerade svenska nationalekonomer före, under och efter kraschen? Vår historia kretsar kring de tre ekonomer som var mest aktiva: Gustav Cassel, Bertil Ohlin och

High-order harmonic generation is a highly nonlinear, though inherently inefficient, process which can lead to emission of coherent, broadband extreme ultraviolet radiation in the form of attosecond pulses. Attosecond pulses are crucial for experiments investigating photoionization dynamics on the femto- and attosecond timescales. As attosecond research tends towards increasingly complex light-mat

Geological time is by many geoscience instructors considered a threshold concept for geoscience students, being a central concept for how we experience geosceince phenomena that takes place on a spatio-temporal scale ranging from micro (e.g. cloud formation) to macro (e.g. plate tectonics). If one wishes to understand geoscience phenomena that goes beyond human perception, one must move from the cGeological time is by many geoscience instructors considered a threshold concept for geoscience students, being acentral concept for how we experience geosceince phenomena that takes place on a spatio-temporal scale rangingfrom micro (e.g. cloud formation) to macro (e.g. plate tectonics).

Wetland area has decreased dramatically compared with preindustrial times, and in manyagricultural areas almost all wetlands have been drained to gain cropland. The trend hasin recent years been reversed because society has realized the many benefits of wetlandfunctions, such as for nutrient retention and flood control. In this study we inventoried 75 wetlands in Uppland and Halland for insects an

Today, huge amounts of data are produced, collected, and presented in all kinds of contexts. The ability to critically examine and evaluate information and arguments in relation to empirical evidence is often referred to as information literacy. It is of utmost importance that students are adequately scaffolded to develop this ability, to be able to become democratic citizens. The study presented

Diversifying cropping systems by increasing the number of cash and cover crops in crop rotation plays an important role in improving resource use efficiency and in promoting synergy between ecosystem processes. The objective of this study was to understand how the combination of crop diversification practices influences the performance of arable crop sequences in terms of crop grain yield, crop an

What information is encoded in the cries of human babies? While it is widely recognized that cries can encode distress levels, whether cries reliably encode the cause of crying remains disputed. Here, we collected 39201 cries from 24 babies recorded in their homes longitudinally, from 15 days to 3.5 months of age, a database we share publicly for reuse. Based on the parental action that stopped th

This paper provides an overview of the Neurigona species found in Iran. During our studies in northern Iran four species of the genus Neurigona Róndani, 1856 have been collected, three of which for the first time in Iran: Neurigona helva Negrobov & Tsurikov, 1990, Neurigona pallida (Fallén, 1823) and Neurigona pseudolongipes Negrobov, 1987. One species, Neurigona persiana Pollet & Kazerani

Three different circulation mechanisms are analyzed: 1) through-flow of a river; 2) wind generated oscillations; and 3) convective currents induced by heat flow from the bottom sediments. The through-flow takes place between the ice and a depth, which is mainly determined by the conditions at the inlet of the river into the lake. Just below this depth there is a sharp thermocline. The water mass b
