The exclusive charmonium production process in pp annihilation with an associated π0 meson pp→J/ψπ0 is studied in the framework of QCD collinear factorization. The feasibility of measuring this reaction through the J/ψ→e+e- decay channel with the AntiProton ANnihilation at DArmstadt (PANDA) experiment is investigated. Simulations on signal reconstruction efficiency as well as the background reject
Background There is limited knowledge on whether prior knee surgery impacts the clinical profile and treatment outcomes for individuals with knee osteoarthritis (OA). Objectives The study aimed to (i) compare individual and clinical characteristics, and (ii) evaluate whether outcomes of first-line treatment differ between individuals with prior knee surgery and those without. Methods This study us
In this chapter we share, reflect and learn from the findings of a long-standing collaboration between two teacher educators who have been working together on the topic of refugee education since 2016. Based in Sweden and England, the two researchers have over that time reflected on the changing educational and political discourse which permeates the contexts in which they work. In this chapter, w
By combining ab initio downfolding with cluster dynamical mean-field theory, we study the degree of correlations in monolayer, bilayer, and bulk breathing-mode kagome van der Waals materials Nb3(F, Cl, Br, I)8. Our new material-specific many-body model library shows that in low-temperature bulk structures the Coulomb correlation strength steadily increases from I to Br, Cl, and F, allowing us to i
Purpose: The purpose of this study is to generate and provide suggestions for strategic actions, adjusted to conditions on the market, on how train operators, operating in a mature, saturated and highly competitive passenger transportation industry, should create an attractive customer offer for business travellers. Methodology: This study is based on a case study of the Swedish train operator SJ.
Den snabba digitala utvecklingen har medfört att immaterialrättsliga tillgångar har ökat i betydelse samt ekonomiskt värde, och i takt med denna utveckling har piratkopieringen kommit att bli ett allt större problem. De senaste tio åren har samtidigt en trendökning skett i praxis vad gäller straffrättsligt ansvar vid piratkopiering. Straffrättsliga förfaranden inom det immaterialrättsliga området The rapid digital development has caused intellectual property rights to increase in importance and economic value. In line with this development, piracy has become an ever-increasing problem. During the last ten years, an increasing trend has also appeared in regards to criminal law proceedings concerning piracy infringements. Criminal proceedings in the field of intellectual property have previo
Bakgrund: Arbete som innefattar mycket datormusanvändning innebär en stor risk för utvecklandet av armbågsproblematik. Ett vanligt förekommande besvär hos kontorsarbetare är lateral epikondylit, vilket oftast beror på repetitivt arbete, oergonomisk arbetsställning och/eller för hög arbetsbelastning. Detta är faktorer som i sin tur ökar muskelaktiviteten. För att förebygga muskuloskeletala besvär h
Växelvis boende med en ungefärlig jämn uppdelning är vanligast förekommande i Skandinavien och har således mestadels studerats i denna kontext. Få studier har dock inriktat sig på yngre barn eller kvalitativt undersökt det växelvisa föräldra- och medföräldraskapet. Som en komponent i förståelsen av barnets tidiga anknytnings- och socioemotionella utvecklingsmiljö, fokuserar vi här på hur föräldrarEqually shared joint physical custody (JPC), is most common in Scandinavia and has thus mostly been investigated within this context. There is, however, limited research concerning younger children and parents’ own perspectives on parenting and coparenting in JPC. As a component of the understanding of the child's early attachment and socioemotional developmental environment, we focus here on
Aluminum (Al), as a carbon-free energy source, features favorable characteristics regarding its production, transportation, utilization, and recyclability. The combustion of single Al particles mainly occurs as a vapor-phase diffusion flame, wherein the gas-phase combustion kinetics plays an important role. However, the understanding of the kinetics is still limited and rate constants for the same
Construction with timber is becoming increasingly popular, partially due to its environmental benefits in comparison to steel and concrete. This is especially true for cross-laminated timber (CLT) panels an engineered wood product consisting of stacked timber lamellae oriented perpendicu-larly to each other. CLT panels have high stiffness in comparison to its mass, which leads to a sensitivity to
Familial adenomatous polyposis (FAP) is caused by germline mutations in the adenomatous polyposis coli (APC) gene. Two promoters, 1A and 1B, have been recognized in APC, and 1B is thought to have a minor role in the regulation of the gene. We have identified a novel deletion encompassing half of this promoter in the largest family (Family 1) of the Swedish Polyposis Registry. The mutation leads to
Gastrointestinal motor dysfunction persists in a large number of children subjected to surgical treatment for Hirschsprung's disease, indicating abnormalities in the remaining intestine. The aim of the study was to detect possible alterations in frequency and topographic distribution of enteric neurons and interstitial cells of Cajal in an experimental model (the lethal spotted mouse displaying a
Acute rheumatic fever (ARF) and acute poststreptococcal glomerulonephritis (APSGN), two important sequelae of streptococcal throat or skin infections, according to current concepts may be elicited by autoimmune mechanisms due to molecular mimicry between group A streptococci (GAS) and human tissue. In the case of APSGN, however, Our experimental data have indicated that GAS immunoglobulin-binding
This thesis makes a contribution to mechanism design: a field of economic theory concerned with constructing and analyzing economic mechanisms. Examples include design of auctions, voting systems, school choice, kidney exchange and many more. The thesis consists of four separate papers. Paper one and two proposes and analyzes two new iterative auction mechanisms for selling multiple heterogeneous
Purpose: Patients with brain tumors constitute a vulnerable group, and it is important that they receive the highest quality of care (QoC). The study aim was to describe the perceptions of QoC and its association with health-related quality of life in brain tumor patients undergoing proton beam therapy in a newly established clinic. Method: Data were collected at the start of treatment and after 3
