This paper discusses the role of mathematics in physics teaching and learning. The intention and strength of science is to describe what happens in the realworld by organizing explanations through theories and theoretical models. It has been widely suggested that learning in science is influenced by views about the nature of scientific knowledge. Furthermore, mathematics is an inherent part of the

University students’ conceptions of differentiability, continuity and relationsbetween these concepts were studied to reveal their choices of representationsand their strategies to justify their relational claims. Questionnaires and interviews were used to collect data. The results were analysed and categorizedthrough a framework based on understanding as connections between concepts,and a theory

Autistic persons often have difficulties with social interaction and communication. Sensory impressions are often processed differently than in neurotypicals. The person may be negatively affected bodily, e.g., being unstable or having reduced body awareness. The body awareness may be observed as an expression in movement quality. However, there is a lack of knowledge about experiences, assessment

Syftet med denna publikation är dels att på ett mer utförligt sätt presentera den information som framkom angående undersökningarna vid Ale stenar i samband med Märta Strömbergs bortgång, dels att sätta denna i relation till Strömbergs arbete med Kåsebergaåsen samt Bengt Söderbergs fortsatta arbete med platsen.Ytterligare ett syfte är att lyfta det fyndmaterial som påträffades i och runtom skeppss

The world is becoming more and more data driven. There are many ways to collect, analyse and disseminate data, and data ecosystems are among the most important environments that we have for facilitating this. Spatial data is one of the data types in data ecosystems, and data ecosystems play a key role in further value creation of the spatial data created, maintained and shared in the SDI. The work

To improve the shelf-life of food products rich in lipids, it is important to minimize the lipid oxidation that occurs during processing, since this oxidation not only decreases shelf-life but also induces off-flavors. To evaluate the oxidation of lipids in the production of one β-glucan-rich and one protein-rich food supplement made from oats (Avena sativa), the neutral and polar lipid profile, h

Segment transitions can be accounted for by acceleration peaks, which appear at the edges of articulatory speech postures. The present study builds on previous research on timing of acceleration, and expands it by investigating magnitude of acceleration peaks at segment offset, comparing stressed and unstressed syllables. Acceleration peaks of lower lip and lower jaw are measured on ten Swedish sp

The paper introduces a new device for analyzing, teaching, and training jaw movements: the MARRYS helmet. We outline the motivation for the development of the helmet, describe its key advantages and features relative to those of the Electromagnetic Articulograph (EMA) and illustrate by means of selected study portraits the possible uses of the MARRYS helmet in the various fields of the empirical a

This paper reports on a corpus of Brazilian Portuguese (BP) mandible movements. The data was collected using a recently available technique, the MARRYS helmet, which allows for quick and reliable collection of mandible data of a large number of speakers. Audio and mandible were recorded from more than 90 L1 and L2 BP speakers. The recording process and signal synchronization are presented. A parti

In vitro digestion studies often use animal digestive enzyme extracts as substitutes of human gastric and pancreatic secretions. Pancreatin from porcine origin is thus commonly used to provide relevant pancreatic enzymes such as proteases, amylase and lipase. Rabbit gastric extracts (RGE) have been recently introduced to provide gastric lipase in addition to pepsin. Before preparing simulated gast

Here we evaluated the levels of lipid oxidation products, fatty acids, ascorbic acid and colour of Porphyra and Ulva after oven-drying at 40 °C, and during subsequent storage for ≥370 days under light, semi-light and dark conditions. Part of the seaweed was pre-soaked in freshwater or pre-coated with a whey protein mixture. Controls consisted of freeze-dried seaweeds. Throughout storage there was

The degradation of trout and bovine hemoglobin (Hb) and their pro-oxidant activities in washed cod muscle mince (WCM) were studied using simple pH-shifts to simulate gastrointestinal (GI) conditions (pH 7 → 6 → 3 → 7), as well as full static in vitro GI digestion. Following gastric acidification to pH 6, metHb formation increased, especially for trout Hb. Subsequent acidification to pH 3 promoted
