Background and purpose — Recent evidence has questioned the effect of arthroscopic knee surgery for middle-aged and older patients with degenerative meniscal tears with or without concomitant radiographic knee osteoarthritis (OA). We investigated the prevalence of early or more established knee OA and patients’ characteristics in a cohort of patients undergoing arthroscopic surgery for a meniscal
Osteoinduction can be enhanced by combining scaffolds with bone morphogenic protein-2 (BMP-2). However, BMP's are known to also cause bone resorption. This can be controlled using bisphosphonates like zoledronic acid (ZA). In this study, we produced two different scaffolds containing silk-fibroin, chitosan, agarose and hydroxyapatite (HA) with and without bioactive glass. The aims of the study wer
Many of the established Swedish crime writers write for both adults and young readers. These authors are successful in the two literary market segments that are dominating the contemporary Swedish book market: crime literature and children’s literature. Can certain developed trademarks in their authorship for adults be used in order to market books for other age groups and to what extent do the au
BACKGROUND: Acute dyspnea affects a large heterogeneous patient group with high mortality and readmission rates.PURPOSE: To investigate if cardiometabolic biomarkers and clinical characteristics predict readmission and death in patients hospitalized for acute dyspnea.METHODS: 65 dyspnea patients at a general internal medicine ward were followed for six months. The combined endpoint was readmission
Objective: The aim of this study was to analyse the impact of maternal BMI at start of pregnancy and maternal weight gain during pregnancy on the risk of various diseases later in life. Methods: In a population-based cohort from southern Sweden, women with at least one delivery registered in the Swedish Medical Birth Register ten or more years before answering a health questionnaire were identifie
Recent years has seen a growth of so-called ”Al-Qaeda franchises”, terrorist groups who formally ally with Al-Qaeda. This study investigates the phenomenon through how one such actor, the “Salafist Group for Preaching and Combat” (GSPC), has developed after its alliance with Al-Qaeda in 2006 and rebranding as ”Al-Qaeda in the Islamic Maghreb” (AQIM). By analyzing GSPC before and after the alliance
We consider simple approximations of variances and covariances for order statistics from the standard extreme value distribution. Exact values and simulation results of the variances and covariances for certain sample sizes are used to determine the validity of the suggested approximations.
Spectra of far-infrared conductivity contain useful information on charge transport at nanoscopic length scales. However. decrypting the mechanisms and parameters of charge transport from the measured spectra is a complex task in nanostructured systems in particular, the conductivity is strongly influenced by charge carrier interaction with surfaces or interfaces between constituents of the compos
Background: Ensiling is a common method of preserving energy crops for anaerobic digestion, and many scientific studies report that ensiling increases the methane yield. In this study, the ensiling process and the methane yields before and after ensiling were studied for four crop materials. Results: The changes in wet weight and total solids (TS) during ensiling were small and the loss of energy
A simulation scheme based on nonequilibrium Green's functions for biased periodic semiconductor heterostructure devices is presented in detail. The implementation can determine current and optical gain both for small and large optical fields. Specific results for superlattices, quantum cascade lasers, and quantum cascade detectors are shown which demonstrate the capabilities of the approach.
Denna uppsats syftar till att skapa förståelse för hur ChatGPT kan användas inom utbildningssektorn för att främja inlärning och kritiskt tänkande bland universitetsstudenter. Studien är baserad på akademisk litteratur som rör inlärning, AI inom utbildning samt kritiskt tänkande. Den empiriska datainsamlingen består av en kvalitativ metod i form av fyra intervjuer varav respondenterna studerar på
Due to the EU Anti-Tax Avoidance Directive, it is the Swedish legislator’s responsibility to introduce certain interest limitation rules to counter aggressive tax planning before the end of 2018. Due to this, and because the legislator considers that there is a distortion between own and borrowed capital, where loan funding is subsidized due to interest-rate deductions, the Swedish Ministry of Fin
Greening projects are becoming increasingly popular as part of urban transitions towards sustainable cities. Many academic studies have shown that under certain conditions these projects do not address or even execrate existing socio-spatial inequalities. This research attempts to explore the narrative on UGI and environmental justice in academic literature and in the practitioner narrative at mun
The purpose of the thesis is to examine to what extent former high ranking state officials are immune for international crimes before foreign national courts. Historically national courts have recognized absolute immunity, but this approach has gradually to some extent changed after the establishment of international tribunals and the International Criminal Court in which official capacity is irre
Den här framställningen behandlar det upphovsrättsliga skyddet för brukskonst. Upphovsrätten ger ett skydd för litterära och konstnärliga verk och brukskonst anges som skyddad verkskategori i exemplifieringen i 1 kap. 1 § 1 st. 6 p. lag om upphovsrätt till litterära och konstnärliga verk (1960:729), URL. Det har de senaste decennierna framförts en allmän åsikt att kraven för ett upphovsrättsligt sIn this thesis the main purpose is to investigate the copyright protection for applied art. The Swedish copyright gives protection for literary and artistic works and applied art is specifically listed as a protected category in the exemplification in the law. In the past decades it has been stated that the requirements for copyright protection of applied art have been reduced to the same level as
The topic of this thesis is to study which women are represented in hair-adds, -advice and -articles. Also, to study in what way representation has changes from 1970s to 21st century. The study is based on eighty-seven volumes from the magazine Veckorevyn from the period 1970-2000. The results shown that representation is mainly white woman, and this reflecting how society views women of other nat
This thesis investigates the implementation of the digital euro, focusing on university students' trust and awareness in the Benelux region. The study addresses a gap in the existing literature by exploring perceptions among students in Belgium, the Netherlands, and Luxembourg. Through a quantitative survey of 390 respondents, the research examines if awareness of the digital euro predicts tru
Spending time outdoors during childhood can improve learning, promote pro- environmental behavior, and improve physical and mental health. However, most of our everyday lives are spent indoors and thus a disassociation from nature is created. Paradoxically, a positive relationship between humans and nature is vital for its preservation, and our survival. Through outdoor education in elementary sch
