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

In 2005 the Swedish Association of the Pharmaceutical Industry (LIF) initiated a national environmental classification and information system for pharmaceuticals. This investigation reports the results from a survey, conducted among the persons involved in the start-up process. The aim of this study is to generate knowledge contributing to the clarification of the motivations, expectations, and in

Podcast "Öppet fall" från Lunds universitet, Juridiska fakulteten: I november 2020 slår en ovanligt stor meteorit ner i skogarna norr om Enköping. Under de följande veckorna söker två geologer systematiskt igenom området tills de hittar meteoriten. När markägaren får höra om fyndet uppkommer en tvist som går till domstol. Markägaren hävdar att meteoriten tillhör honom, medan geologerna hävdar att

As the total cost of renewable electricity falls lower than the price of fossil fuel, not only can electricity be used to replace fossil fuels using batteries in vehicles but it can also be used to produce fuels. This makes it possible to replace fuels in sectors not easily directly electrified. It also provides new ways of balancing the electricity system. When renewable electricity is cheap a lo

Medical, neurological, and substance use disorders constitute a major disease burden worldwide, but especially in low- and middle-income countries (LMICs) where more than 80% of affected persons are unable to receive evidence-supported treatments despite these being widely available in theory. This persistent mental health treatment gap in LMICs is traceable to the very nature of such nations: low

The use and significance of timber structures are on the rise, especially thanks to crosslaminated timber (CLT). This engineered wood product is manufactured by stacking multiple layers of wood lamellae, each oriented perpendicularly to the one below it, and then bonding them with adhesives to form a floor or wall panel. Timber, as a building material, presents potential environmental benefits ove

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

Quinoa (Chenopodium quinoa Willd.) has gained recent popularity mainly due to its attractive nutritional profile and its ability to grow under extreme conditions such as salinity, acidity, drought, flooding, and frost as well as the functionality of its component. Starch is the main component of quinoa grain which constitutes up to 60% of the dry grain and plays a crucial role in the functional pr

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

How can cities and communities around the world become more sustainable? What can we do as researchers to help them? As we move through the twenty-first century, these questions assume ever-greater importance. Many of the quickest wins for human and planetary health involve reimagining and reconfiguring cities. Activities that generate negative impacts like air pollution and poor health are concen

Många arbetsgivare känner inte till att de redan idag använder sig av artificiell intelligens, AI, eller annat automatiserat beslutsfattande. Det visar den rapport om AI och risker för diskriminering i arbetslivet som Diskrimineringsombudsmannen, DO, publicerar idag. Att arbetsgivare har denna kunskap är avgörande för att arbeta förebyggande för att motverka diskriminering vid tillämpning av tekni

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

Background: Treatment of common bile duct (CBD) stones after Roux-en-Y gastric bypass (RYGB) poses a particular challenge given the altered anatomy and inability to perform a standard endoscopic retrograde cholangiogram (ERC). The optimal treatment strategy for intraoperatively encountered CBD stones in post-RYGB patients has not been established. Objectives: To compare outcomes following laparosc

A microenvironment is an area with a specific composition of mainly extracellular matrix (ECM) components surrounding the cells. The tight interactions between matrix molecules and cells are very important, and it is now well known that the ECM components direct cell activity and function and regulate remodeling processes during both homeostasis and pathological conditions. The lung is a very comp

Knowledge in statistics is essential to draw solid conclusions from data. This chapter covers the basic concepts needed to navigate in the world of biostatistics, with the aim that the reader should know what to search for when encountering new situations. First, the chapter introduces basic concepts such as scales of measurement, relation between sample and population, and features of stochastic

Introduction: Housing shortage due to population growth within metropolitan areas, combined with an ageing population, has put pressure on current housing provision in Sweden. Thus, there is an urgent need to develop sustainable housing policies to accommodate the growing number of seniors in accessible home environments. This study aimed to gain an in-depth understanding of how municipalities cur
