A study of pre-service primary school teachers’ content knowledge regarding real numbers related to infinity,i.e., division by zero and denseness of the real number line, was conducted at a Swedish university. Data werecollected twice during the respondents’ teacher education using questionnaires and interviews on bothoccasions. The data were analysed in terms of traces of concept images, focusing

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

En artikel om den svenska kompositören och musikern "Trubaduren", som skriver supportervisor för AIK:s supportrar, till AIK:s matcher. Studien fokuserar polisen så som den gestaltas i sångerna.

ObjectiveTo investigate whether information about the gender, ethnicity, and socioeconomic status of the patient affects psychiatric assessments in a sample of practicing clinicians in Swedish adult psychiatry.MethodThe study used an experimental design in which vignettes describing patients were identical except for information regarding their gender, ethnicity, and socioeconomic status. The outc

Since the immensely influential work of J. Louis Martyn, many Johannine scholars have interpreted John’s ἀποσυνάγωγος passages (9:22, 12:42, 16:2) as reflective of the gospel’s outsider position in relation to Jewishness. In Martyn’s model, as well as in the model of his contemporary Raymond E. Brown, “the synagogue” functioned as synecdoche for “Judaism,” leading both scholars to the conclusion t

Recent suggestions propose that the glacial landscape in southern Sweden is primarily a relict from the Saalian glaciation (>130 ka). The arguments for this standpoint are the assertion that the majority of glaciofluvial deposits in this region are till-covered, and that wind-abraded clasts are observed at the contact between glaciofluvial sediments and till at numerous locations. Furthermore, it

Manufacturing companies can contribute to a resource-efficient society by designing product-service systems (PSS). Despite the increased importance of PSS for the manufacturing industry in their efforts to become sustainable, few studies focus on small and medium-sized enterprises (SMEs). The study presented in this article aims to add knowledge on how the characteristics of SMEs influence the cha

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of methylxanthines (caffeine; theophylline or aminophylline) and 'no methylxanthine administration' on morbidity and mortality in preterm infants, using network meta-analysis.

The Siljan region hosts Europe´s largest impact structure. The high-relief landscape, with a central granite dome bordered by lake basins, contains an array of glacial and shore-level landforms. We investigated its deglaciation history by mapping and analysing landforms on high resolution LiDAR-based Digital Surface Models coupled with well-dated sediment successions from peat and lake sediment co

In this essay, I offer the first sustained scholarly discussion of the Know Yourself Skeleton Mosaic (KYSM) within its broader cultural milieu and of its contribution to our understanding of self-knowledge in antiquity. In many ways, the mosaic represents an innovative visual "blend" of several cultural tropes and symbols known from the Greco-Roman world. For example, only here is the concept of s

Walter Benjamin’s complex notion of time, permeating much of his historical, political, and cultural-critical thought, has been the subject of considerable discussion. In particular, the interaction between the two opposing categories of historical time and messianic time poses a great difficulty: how do messianic moments of cessation act within the homogeneous continuum of history? To propose one

The Light Dark Matter eXperiment (LDMX) is an electron-beam fixed-target experiment designed to achieve comprehensive model independent sensitivity to dark matter particles in the sub-GeV mass region. An upgrade to the LCLS-II accelerator will increase the beam energy available to LDMX from 4 to 8 GeV. Using detailed GEANT4-based simulations, we investigate the effect of the increased beam energy

Recent suggestions propose that the glacial landscape of southern Sweden is a relict landscape from the Saalian glaciation (>130 ka) (Lagerbäck, 2018). The primary argument supporting this viewpoint is the claimed observation that the majority of glaciofluvial deposits in this region exhibits a covering till bed, often accompanied by wind-abraded clasts (ventifacts) at the contact between glaciofl

Paleo-proxy data indicate that a “Green Sahara” thrived in northern Africa during the early- to mid-Holocene (MH; 11 000 to 5000 years before present), characterized by more vegetation cover and reduced dust emissions. Utilizing a state-of-the-art atmospheric chemical transport model, TM5-MP, we assessed the changes in biogenic volatile organic compound (BVOC) emissions, dust emissions and seconda

Research on microplastics in Latin America is limited compared to a global perspective. Brazil plays a significant role in this context, as it possesses 12% of the world’s freshwater reserves, constituting 53% of South America’s water resources. There has been growing concern regarding the plastic pollution of the country’s freshwater systems in recent years. Therefore, this study investigated the

Background: Impaired quadriceps muscle strength after anterior cruciate ligament reconstruction (ACLR) is associated with worse clinical outcomes and a risk of reinjuries. Yet, we know little about quadriceps muscle strength in patients reconstructed with a quadriceps tendon (QT) graft, which is increasing in popularity worldwide. Purpose: To describe and compare isokinetic quadriceps strength in

Wind-abraded cobbles (ventifacts) and aeolian sand are known from the sandy-gravelly coastal areas of south-western Sweden, especially in association with raised deltas. Ventifacts are recorded on at least two different stratigraphic levels, on top of glaciofluvial sediment and/or on top of littoral deposits, while aeolian sand usually forms a surficial cover. The formation of ventifacts has usual

Objective: We aimed to compare the genetic contribution to osteoarthritis (OA) versus other rheumatic/musculoskeletal diseases (RMDs) in the same population and to explore the role for any shared genetics between OA and other RMDs. Methods: In 59,970 Swedish twins aged 35 years or older, we estimated the heritability (the variance explained by genetic factors) of OA in peripheral joints, back and
