- We report on fabrication of double quantum dots in catalytically grown InAs/InP nanowire heterostructures. In the few-electron regime, starting with both dots empty, our low-temperature transport measurements reveal a clear shell structure for sequential charging of the larger of the two dots with up to 12 electrons. The resonant current through the double dot is found to depend on the orbital coupling between states of different radial symmetry. The charging energies are well described by a capacitance model if next-neighbor capacitances are taken into account.

Tidskriftsartikel (refereegranskat)abstract
- Accelerometrar används i stor utsträckning inom forskning och i viss grad i klinisk verksamhet för att fastställa fysisk aktivitet, men de ställer krav på användarna. God kännedom krävs om utformning av mätprotokoll och bearbetning av rådata till användbara mått, som kan användas i lämpliga statistiska analyser för att undvika mätfel.Mätfel medför felskattning av den fysiska aktiviteten, uteblivna gruppskillnader, försvagade samband med hälsa och felaktiga slutsatser om interventionseffekter.Mätning av fysisk aktivitet i klinisk verksamhet främjas genom samarbete mellan kliniskt verksamma, kliniska forskare och forskare med metodologisk kompetens inom fysisk aktivitetsmätning.

- The development of accelerometers has revolutionized measurement of physical activity, and they are used to a large extent in research and have started to be implemented into clinical settings. However, achievement of reliable outcomes requires good methodological knowledge and skills by the user. Otherwise, significant measurement errors may occur, interfering with assessment of the physical activity level in the population, group differences, associations with health parameters or effect of treatments. This paper by the Swedish Network for Objective Measurement of Movement (NORM) provides an overview of physical activity measurement including sections of data collection, processing of raw data into useful metrics and statistical analysis. It targets users of accelerometer in research, health care and national surveys.

Failure of generic risk assessment model framework to predict groundwater pollution risk at hundreds of metal contaminated sites : Implications for research needs
- 2020
-
Ingår i: Environmental Research. - : Elsevier. - 0013-9351 .- 1096-0953. ; 185, s. 1-9

Tidskriftsartikel (refereegranskat)abstract
- Soil pollution constitutes one of the major threats to public health, where spreading to groundwater is one of several critical aspects. In most internationally adopted frameworks for routine risk assessments of contaminated land, generic models and soil guideline values are cornerstones. In order to protect the groundwater at contaminated sites, a common practice worldwide today is to depart from health risk-based limit concentrations for groundwater, and use generic soil-to-groundwater spreading models to back-calculate corresponding equilibrium levels (concentration limits) in soil, which must not be exceeded at the site. This study presents an extensive survey of how actual soil and groundwater concentrations, compiled for all high-priority contaminated sites in Sweden, relate to the national model for risk management of contaminated sites, with focus on As, Cu, Pb and Zn. Results show that soil metal concentrations, as well as total amounts, constitute a poor basis for assessing groundwater contamination status. The evaluated model was essentially incapable of predicting groundwater contamination (i.e. concentrations above limit values) based on soil data, and erred on the "unsafe side" in a significant number of cases, with modelled correlations not being conservative enough. Further, the risk of groundwater contamination was almost entirely independent of industry type. In essence, since neither soil contaminant loads nor industry type is conclusive, there is a need for a supportive framework for assessing metal spreading to groundwater accounting for site-specific, geochemical conditions.

Towards a more sustainable future: simple and effective recommendations to integrate planetary health into education
- 2023
-
Ingår i: The Lancet Planetary Health. - 2542-5196. ; 7:10, s. e868-e873

Forskningsöversikt (refereegranskat)abstract
- This Personal View presents recommendations aimed at integrating planetary health into various stages of education, which are simple but effective, and designed with teachers in training and those who have not yet considered how to incorporate UNESCO’s Education for Sustainable Development into their teaching practice. However, the constantly evolving nature of the Education for Sustainable Development programme must be recognised, and the importance of being able to adapt teaching methods to meet the changing needs of students as they progress through their educational journey should be highlighted. Therefore, this Personal View considers the cognitive, social, and ethical evolution of students and offers specific recommendations for preschool, primary, secondary, and university education levels. We recommend that educators should focus on teaching students to critically evaluate data on sustainability and to develop innovative solutions to environmental challenges. We also highlight the importance of incorporating practical projects, using active methods that promote skills related to caring for the planet, or the importance of situated learning that attends to the particularities of each context. In this way, students can develop skills and values that contribute to a more sustainable future. The recommendations made here aim to provide educators and researchers with simple but effective ways to integrate planetary health into education.

Tidskriftsartikel (refereegranskat)abstract
- We report tunneling spectroscopy measurements of the Zeeman spin splitting in InAs few-electron quantum dots. The dots are formed between two InP barriers in InAs nanowires with a wurtzite crystal structure grown using chemical beam epitaxy. The values of the electron g factors of the first few electrons entering the dot are found to strongly depend on dot size. They range from close to the InAs bulk value in large dots vertical bar g(*)vertical bar=13 down to vertical bar g(*)vertical bar=2.3 for the smallest dots.

Unveiling Connections: A Thorough Analysis of Sustainable Development Goals Integration within the Spanish Physical Education Curriculum
- 2024

Ingår i: Education Sciences. - 2227-7102. ; 14:1
-
Tidskriftsartikel (refereegranskat)abstract
- This study analyses the relationship between the Physical Education (PE) curriculum in Secondary Education in Spain and the Sustainable Development Goals (SDGs). The Physical Education curriculum of Compulsory Secondary Education, as well as the complementary materials, were analysed through document analysis. Although there is no explicit relationship, the analysis reveals links between curricular elements and SDGs targets, particularly with SDG 4 (Quality Education), 3 (Health and Well-being), and 5 (Gender Equality). Other SDGs, such as 10 (Reducing Inequalities) and 12 (Responsible Consumption), are less related. The social dimension of sustainable development is most closely linked to PE. A historical analysis of the treatment of sustainable development in PE curricula in Spain is also presented, examining how they have evolved over time. The manuscript helps clarify how teachers and researchers can mobilize competencies to address global challenges in students' lives as individuals and world citizens, fostering commitment and social responsibility. Furthermore, this work highlights the importance of integrating the SDGs into education and how PE can be a key tool in this process.

Physical Literacy in Europe: The Current State of Implementation in Research, Practice, and Policy
- 2023
-

Tidskriftsartikel (refereegranskat)abstract
- The holistic concept of physical literacy (PL) embraces different person-centered qualities (physical, cognitive, affective/psychological) necessary to lead physically active lifestyles. PL has recently gained increasing attention globally and Europe is no exception. However, scientific endeavors summarizing the current state of PL in Europe are lacking. Therefore, the goal of this study was to comprehensively assess and compare the implementation of PL in research, policy, and practice across the continent. We assembled a panel of experts representing 25 European countries. Employing a complementary mixed-methods design, the experts first prepared reviews about the current state of PL in their countries (categories: research, practice/policy). The reviews underwent comparative document analysis ensuring a transnational foureyes principle. For re-validation purposes, the representatives completed a quantitative survey with questions reflecting the inductive themes from the document analysis. The document analysis resulted in ten disjunct themes (related to “concept”, “research”, “practice/policy”, “future/prospect”) and yielded a heterogenous PL situation in Europe. The implementation state was strongly linked to conceptual discussions (e.g., existence of competing approaches), linguistic issues (e.g., translations), and country-specific traditions. Despite growing scholarly attention, PL hesitantly permeates practice and policy in most countries. Nevertheless, the experts largely anticipate increasing popularity of PL for the future. Despite the heterogeneous situation across Europe, the analysis has uncovered similarities among the countries, such as the presence of established yet not identical concept. Research should intensify academic activities (conceptuallinguistic elaborations, empirical work) before PL may gain further access into practical and political spheres in the long term.

Effects of pH, salt and time on ligand binding properties of overexpressed melanocortin 4 receptor.
- 2004

Tidskriftsartikel (refereegranskat)abstract
- The G-protein coupled melanocortin 4 receptor (MC4r) plays an important role in the energy metabolism. We overexpressed the MC4r in CHO cells and performed characterisation studies on the cell membranes to determine functional stability and ligand binding properties of the receptor. The affinity for the ligands [Nle4, Image-Phe7]-αMSH and MTII was lost below pH 6 but could be restored by returning to physiological pH. Increasing NaCl concentration up to 1 M had little influence on the binding of either ligand. At neutral pH, physiological salt concentration and 4 °C the ligand affinity of the receptor was stable for up to 6 days. These findings will facilitate design of purification methods for the receptor.
