This study is part of a larger study of mathematics in physics teaching at upper secondary school. In this paper we focus on the use of mathematics in relation to the teaching of specific heat capacity of water. We report from two physics lessons with first-year students (lecture, problem solving, and labwork). One observation is the frequent technical use of mathematics during the lessons, which

Sjuktalet och arbetslöheten samvarierar, genom att sjukfrånvaron tenderar att öka då arbetslösheten minskar, och vice versa. I uppsatsen diskuteras denna samvariation samt dess rekation till förtidspensionering, och den dolda arbetslösheten.

Popular Abstract in Swedish Bilsäten har genomgått en kontinuerlig utveckling ända sedan de först beskrevs år 1885. På den tiden kunde man läsa om vadderade läderbänkar, monterade på stora fjädrar, fastsatta i chassit på ”hästlösa vagnar”. När polyuretanskum först började tillverkas på 1950-talet introducerades de snabbt i bilsätena och dessa genomgick stora förbättringar. Skummen utgör idag en stAutomotive seating has been under continous development since it was described for the first time in 1885. At that time one could read about a “padded leather bench seat sitting on springs mounted directly to the frame of a horse-less carriage”. With the development of flexible polyurethane foam in 1950-1960 the seats were considerably improved and the traditional springs were eventually replaced

Emissions of greenhouse gases in all sectors of society must reach near zero, in developed countries preferably by 2050, in order to reach climate policy objectives. Alternatives and strategies for the energy and transport sectors are relatively well understood but the basic industries are often overlooked, not least in sustainability transition and innovation system studies. The policy and techn

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Utvecklingen av nya innovativa chokladprodukter har tagit fart under de senaste åren i takt med att konsumenterna ställer allt högre krav på chokladkvaliteten. Eftersom produktionsprocessen är komplicerad och hållbarhetstiden begränsad uppskattas att man slänger drygt 100 000 ton chokladprodukter varje år i Europa till ett värde av 1.Abstract Fat bloom on chocolate is a major problem for the confectionery industry since the unappetising appearance and negative sensory effects lead to rejection by customers. The presence of fat bloom on chocolate confectionery systems is usually connected to migration of liquid fat due to the difference in composition between filling triacylglycerols (TAGs) and cocoa butter TAGs. The filling T

The paper examines and illustrates different trends in relation to historical energy use-related intensities and corresponding CO2 emission trends. The methodology encompasses a decomposition quantitative approach for estimating decoupling trends to energy use and economic and demographic parameters driving CO2 emission levels. The analysis covers both global and regional trends for the period 197

A stochastic hierarchical model for the evolution of low grade gliomas is proposed. Starting with the description of cell motion using a piecewise diffusion Markov process (PDifMP) at the cellular level, we derive an equation for the density of the transition probability of this Markov process based on the generalised Fokker–Planck equation. Then, a macroscopic model is derived via parabolic limit

Numerous risks threaten modern society. Some are new, while others have existed since the beginning of time, but none have been governed on a societal level since their inception. Despite the abundance of literature addressing the governance of various risks, the processes by which they become governable in the first place have gotten little attention. As a result, this paper aims to improve our k

Over the last thirty years, suggestions for how to develop defence capability have developed rapidly. However, supporting theory and structured concept development lag behind. Despite this imbalance, countries need to continuously spend resources on defence development. This study identifies central challenges in relation to the scientific perspectives and approaches needed to support the developm
