Sequentially N-Doped Acceptor Primer Layer Facilitates Electron Collection of Inverted Non-Fullerene Organic Solar Cells

In most non-fullerene organic solar cells comprising bulk-heterojunction active layers, the inter-domain connectivity of small-molecule acceptors is generally inferior to those of polymeric donors due to their intrinsic short-range ordering. This issue is even exacerbated by the physiochemical mismatch between acceptor-phases and metal-oxide electron transport layers in most inverted n-i-p devices

Disruption of the TP53 locus in osteosarcoma leads to TP53 promoter gene fusions and restoration of parts of the TP53 signalling pathway

TP53 is the most frequently mutated gene in human cancer. This gene shows not only loss-of-function mutations but also recurrent missense mutations with gain-of-function activity. We have studied the primary bone malignancy osteosarcoma, which harbours one of the most rearranged genomes of all cancers. This is odd since it primarily affects children and adolescents who have not lived the long life

Recovering from physical trauma in late life, a struggle to recapture autonomy : A grounded theory study

Aim: The study aimed to explore the experiences of care and recovery among older patients treated for physical trauma. Design: A qualitative study with a constructivist grounded theory design. Methods: Fifteen in-depth interviews with older adults recovering from physical trauma were conducted and analysed between 2019 and 2023, in accordance with grounded theory methodology. Results: The findings

Implementation of dosimetry for molecular radiotherapy; results from a European survey

Purpose: The use of molecular radiotherapy (MRT) has been rapidly evolving over the last years. The aim of this study was to assess the current implementation of dosimetry for MRTs in Europe. Methods: A web-based questionnaire was open for treating centres between April and June 2022, and focused on 2020–2022. Questions addressed the application of 16 different MRTs, the availability and involveme

The Sealing Capacity And Heat Transfer Characteristics Of A Straight-Through Labyrinth Seal With Different Geometric Parameters

The sealing capacity and heat transfer characteristics of the straight-through labyrinth seal with different geometric parameters are analyzed in this paper through numerical investigation. The geometric parameters studied include the gap width varying from 2 mm to 6 mm, the tooth tip thickness varying from 1 mm to 3 mm, and the front inclination angle varying from 75° to 100°. For each case, the

Redemption Through Play? Exploring the Ethics of Workplace Gamification

Today, it is becoming increasingly common for companies to harness the spirit of play in order to increase worker engagement and improve organizational performance. This paper examines the ethics of play in a business context, focusing specifically on the phenomenon of workplace gamification. While critics highlight ethical problems with gamification, they also advocate for more positive, transfor

Sveriges anpassning till Europakonventionen om kommunal självstyrelse

Efter det att Sverige ratificerade Europakonventionen om kommunal självstyrelse (the European Charter of Local Self-Government) 1989, den s.k. självstyrelsekonventionen, har ett antal reformer av det lokala och regionala självstyret ägt rum. Frågan är i vilken utsträckning dessa reformer kan ses som anpassningar till konventionen. Analyser av granskningsrapporter och förarbeten indikerar att refor

Wollstonecraft, Mary

Mary Wollstonecraft (1759–1797) was an English philosopher in the Enlightenment tradition, writer, novelist, and book reviewer. She was an advocate for women’s rights and for equality of wealth and privilege and supported the French Revolution. She made her name in 1790 as the author of A Vindication of the Rights of Men, the first published commentary on Edmund Burke’s critique of the French Revo

Climate and dispersal limitation drive tree species range shifts in post-glacial Europe : results from dynamic simulations

Introduction: The ability of species to colonize newly suitable habitats under rapid climate change can be constrained by migration processes, resulting in a shift of the leading edge lagging behind the ameliorating climate, i.e. migration lag. The importance and extent of such migration lags during the forest expansion after the Last Glacial Maximum (LGM) are still debated. Similarly, the relativ

Ligand-centered to metal-centered activation of a Rh(iii) photosensitizer revealed by ab initio molecular dynamics simulations

Excited state evolution of the rhodium(iii) complex [Rh(iii)(phen)2(NH3)2]2+ (phen = 1,10-phenanthroline) has been investigated theoretically to gain a better understanding of light-driven activation of high-energy metal centered states. Ab initio molecular dynamics (AIMD) simulations show the significance of asymmetric motion on a multidimensional potential energy landscape around the metal cente

Other Important Elements

In addition to the major nutrients carbon, nitrogen, and phosphorus, many minor elements play an important role in the function of freshwater systems. Such elements may function as essential micronutrients, or they may affect the biota by being toxic, or they play an indirect role by influencing the mobility and availability of other elements. This chapter covers the fundamentals of important mino

Effect of polymer addition on the phase behavior of oil-water-surfactant systems of Winsor III type

Ternary oil-water-surfactant systems can give rise to an O/W microemulsion in equilibrium with excess oil, a W/O microemulsion in equilibrium with excess water, or a bicontinuous microemulsion in equilibrium with excess oil and water. This type of phase behavior has been known for a long time and the three systems are often referred to as Winsor I, Winsor II and Winsor III, respectively after the

Perspectives of current understanding and therapeutics of Diamond-Blackan anemia

Diamond-Blackfan anemia (DBA) is a rare congenital bone marrow failure disorder characterized by erythroid hypoplasia. It primarily affects infants and is often caused by heterozygous allelic variations in ribosomal protein (RP) genes. Recent studies also indicated that non-RP genes like GATA1, TSR2, are associated with DBA. P53 activation, translational dysfunction, inflammation, imbalanced globi

Claims in the clinic : A qualitative group interview study on healthcare communication about unestablished side effects of the copper IUD

Background Lay online communication about health-related issues has in recent years largely been associated with the spread of misinformation and decreased trust in healthcare. Such communication has included claims about systemic side effects of the copper IUD. In Sweden, a social media group centered on this issue now gathers around 8,700 members. This study aimed to use the case of reported yet

The 18-item Swedish version of Ryff’s psychological wellbeing scale : psychometric properties based on classical test theory and item response theory

Background: Psychological wellbeing is conceptualized as the full engagement and optimal performance in existential challenges of life. Our understanding of psychological wellbeing is important for us humans to survive, adapt, and thrive during the challenges of the 21st century. Hence, the measurement of psychological wellbeing is one cornerstone for the identification and treatment of both menta

The Gendered Possibilities for Participating in Agricultural Intensification in Sub-Saharan Africa – a Longitudinal Perspective from Seven Regions in Malawi, Tanzania and Zambia

This paper looks at the gendered possibilities for participating in agricultural intensification in seven regions in Malawi, Zambia and Tanzania, using a longitudinal, regional, mixed methods approach combining household level data on land, labour and use of agricultural techniques for male and female farm managers as well as qualitative data collected from within male-headed households and commun

Vägvalet efter Tesla

Vårt land har inte blivit rikt och fritt genom monopol och korporativism. Striden mellan LO och Tesla pekar på en central fråga: ska det svenska samhället vila på individorienterad grund eller starka särintressen?
