The main aim of this article is to discuss the attitudes to mathematics of students taking a basic mathematics course at a Swedish university, and to explore possible links between how well such students manage to solve tasks about limits of functions and their attitudes. Two groups, each of about a hundred students, were investigated using questionnaires, field notes and interviews. From the resu

Students at a Swedish university were subjects in a study about learning limits of functions. The students' perceptions were investigated in terms of traces of concept images through interviews and problem solving. The results imply that most students' foundations were not sufficiently strong for them to understand the concept of limit well enough to be able to form coherent concept images. The tr

BACKGROUND: Cell blocks (CBs) are widely used for biomarker analyses such as immunostaining. Although immunohistochemistry on formalin-fixed paraffin-embedded tissues is standardized, there are multiple preparation methods and fixatives for cytology. Our objective was to investigate the effect of different common fixatives on the immunoreactivity of pleural effusion CBs with metastatic lung adenoc

Biomass is often viewed as a primitive source of energy that needs to be modernized. However, itis unlikely that preferred modern energy sources will displace traditional biomass-based energyin the near term, especially in rural Africa and southeast Asia (FAO 2017). Demand for sustainablysourced biomass is likely to increase as the world moves away from fossil fuel dependence andtransitions to sus

Populärvetenskaplig sammanfattningIntroduktionI dagens digitala era har sociala medier och internet blivit centrala plattformar för nyhetsförmedling och offentlig debatt. Denna utveckling har främjat snabbare informationsspridning och ökat engagemang i samhällsfrågor. Samtidigt har det också medfört en ökning av negativa påtryckningar i form av trakasserier, hat och allmänt ogillande, särskilt rikIntegrating socio-legal analysis and working life science, this compilation thesis aims to enhance the understanding of how the evolving digital landscape—particularly the rise of online harassment—influences journalism and its potential to foster healthy public discourse. Additionally, the thesis seeks to advance the field of socio-legal studies by examining the interplay between digital transfor

Quantification of in vivo proton magnetic resonance spectra (1H-MRS) still commonly involves evaluation of exclusively the real part of acquired spectral signals, but ignoring the information contained in the imaginary component may limit precise identification of individual metabolite contributions. Here, we assess quantification precision relative to SNR and noise correlation for both real and c

Although Sweden is a top country for gender equality, there are disparities in domestic labor and parental leave use between men and women. The COVID-19 pandemic changed work-home life by increasing remote work. This study explored eight fathers’ work-family experiences in Sweden before, during and since the COVID-19 pandemic using interviews. Three group themes were developed using InterpretativeAlthough Sweden is a top country for gender equality, there are disparities in domestic labor and parental leave use between men and women.

Groundwater is Earth’s largest liquid freshwater resource. It is a significant component of the hydrological cycle and a buffer that sustainsrivers and freshwater-dependent ecosystems during droughts. Approximately half of the world’s population depends on groundwater fordrinking water, food, and hygiene. It is used extensively in agricultural irrigation, food production and for industrial process

ObjectivesIndividuals who die by suicide often consult their general practitioners (GPs) in their final weeks of life. The aim of this study was to gain a deeper knowledge of the clinical characteristics and GP assessments and treatments among individuals who consulted their GPs during the month preceding suicide. Further, we compared these features in those with and without contact with psychiatr

Starch in Food: Structure, Function and Applications, Third Edition is now fully updated with eleven new chapters covering "hot" areas for starch applications, such as starch-based pickering emulsifiers, starch for structuring gluten-free bread products, and starch microspheres for encapsulation of probiotic bacteria. Sections illustrate how plant starch can be analyzed and modified, including cha

Starch, a vital food ingredient from diverse sources, possesses a complex molecular structure with amylopectin and amylose polymers. The polymers vary greatly in size, molar mass, and branching, often displaying very polydisperse size distributions and considerable among ultra-high molar mass polymers. This renders the analysis and characterization of starch polymers a challenging task. This chapt

Starch which has been modified with octenyl succinic anhydride (OSA) is an efficient emulsifier for food emulsions. The presence of the OSA groups renders the starch polymers surface active and allows for their adsorption at the oil-water interface. Due to the large size of the starch polymers, adsorbed starch offers efficient steric stabilization of emulsions. Stability is achieved also at low pH

We demonstrate detection and measurement of electron paramagnetic spin resonances (EPR) of iron defects in β-Ga2O3 utilizing generalized ellipsometry at frequencies between 110 and 170 GHz. The experiments are performed on an Fe-doped single crystal in a free-beam configuration in reflection at 45∘ and magnetic fields between 3 and 7 T. In contrast with low-field, low-frequency EPR measurements, w
