The relation between catalytic activity and the presence of oxides on the catalyst’s surface has proven very complex, especially in the case of methane oxidation over Pd. While the metallic Pd surface and a thin, but at least two atomic layers thick, oxide film has been found catalytically active, a single-layer surface oxide or a too thick oxide film are both low-active. Unfortunately, under reac

The avian genus Calandrella (larks) was recently suggested to be non-monophyletic, and was divided into two genera, of which Calandrella sensu stricto comprises 4–5 species in Eurasia and Africa. We analysed mitochondrial cytochrome b (cytb) and nuclear Restriction-site Associated DNA (RAD) sequences from all species, and for cytb we studied 21 of the 22 recognised subspecies, with the aim to clar

Combatting migrant smuggling has become a prominent objective of the European Union’s (‘EU’) migration policy in response to an increase of arrivals from 2015 onwards. The increasing number of arrivals also resulted in an increase in the activity of individuals, non-governmental organisations and other groups providing humanitarian assistance. This thesis explores the relationship between the prov

This work investigates single-sensor localization of acoustic emissions (AEs) along a wind turbine blade with supervised neural networks. We evaluate six architectures: a Dense MLP, a 1D CNN on time-domain inputs, two 2D CNNs on linear spectrograms (LinSpec) and mel-spectrograms (MelSpec), a CRNN (2D CNN + LSTM), and RepVGG (Mini RepVGG in simulation, RepVGG-A0 in experiments). Three experimental

Aims Methadone and buprenorphine diversion by patients in opioid substitution treatment (OST) is a poorly understood phenomenon. We study the norms and attitudes on diversion among OST patients, including the role these norms and attitudes play as diversion risk factors. We also study whether perceived quality of care, social bonds to treatment staff, and deterrence can be associated with diversio

Denna uppsats undersöker hur EU:s konkurrenslagstiftning reglerar interoperabilitetsskyldigheter för dominerande digitala plattformar. Uppsatsen visar hur EU-domstolens avgörande i Android Auto (C-233/23) omformar teorin om nödvändiga nyttigheter (Essential Facilities Doctrine, EFD) som etablerades i Bronner-domen (C-7/97). Vidare analyseras denna framväxande doktrins samspel med de interoperabiliThis thesis explores how EU competition law governs interoperability obligations for dominant digital platforms. It shows how the CJEU’s judgment in Android Auto (C-233/23) redefines the Essential Facilities Doctrine (EFD) established in Bronner judgment (C-7/97) and how this emerging doctrine interacts with the interoperability obligations introduced by the Digital Markets Act (DMA). The Android

Parkinson’s disease (PD) is a progressive neurodegenerative disease, characterized by degeneration of dopaminergic neurons, leading to notable difficulties with one’s movement. Among different treatment options, stem cell replacement therapies have been recognized as an option to not only treat disease symptoms but to address its underlying cause- neuronal degeneration. This can be achieved throug

Objectives We aimed to describe clinical and diagnostic characteristics of primary care patients with heart failure and physicians’ adherence to guideline-directed medical therapy (GDMT) for treating chronic heart failure. Design Cross-sectional study based on baseline data from the prospective primary care-based study Heart failure in Southern Sweden (HISS). Setting Patients with heart failure we

I Sverige vänds omkring 50.000 barns liv upp och ner varje år, när deras föräldrar väljer att gå skilda vägar. Det som en gång varit barnets trygghet och hela värld, rivs upp och känns istället skrämmande och otryggt. Föräldrarnas viljor och känslor styr processen, vilket gör att barnen allt som ofta hamnar i kläm. I en majoritet av fallen löser föräldrarna barnets boende, vårdnad och umgänge gemeIn Sweden the lives of about 50.000 children are turned upside down every year, just because their parents have choosen to separate. What has once been the childs secure and safe world, are now ripped apart and frightening instead. The wills of the parents and their emotions, can greatly impact the decisions of the jucidial process which can in turn have a catasprohic backlash on the child. In the

1. Ecological stoichiometry predicts important control of the relative abundance of the key elements carbon (C), nitrogen (N) and phosphorus (P) on trophic interactions. In a nutrient-poor Amazonian lowland rain forest of French Guiana, we tested the hypothesis that decomposers exploit stoichiometrically diverse plant litter more efficiently, resulting in faster litter decomposition compared to li

This work consists of seven essays, with each concerning a specific subject that is related to architecture. There is additional text, which pertains to this work's examination requirements for graduating the architecture-program at Lund Technical University. This work is a creative explorations through writing as a tool; through text; becoming able to formulate, conceptualize, develop and ext

Efficient and clean production of electrical and mechanical energy for use in industry, transportation and propulsion is currently a concern. The transition from fossil fuels to biofuels involves challenges related to the fuel composition and combustion, as well as methods to increase engine fuel flexibility. One potentially useful tool under development is Plasma Assisted Combustion (PAC), where

The widespread use of artificial nestboxes has led to significant advances in our knowledge of the ecology, behaviour and physiology of cavity nesting birds, especially small passerines Nestboxes have made it easier to perform routine monitoring and experimental manipulation of eggs or nestlings, and also repeatedly to capture, identify and manipulate the parents However, when comparing results ac

Background Endometrial adenocarcinoma (womb cancer) is a malignant growth of the lining (endometrium) of the womb (uterus). It is distinct from sarcomas (tumours of the uterine muscle). Survival depends the risk of microscopic metastases after surgery. Adjuvant (postoperative) chemotherapy improves survival from some other adenocarcinomas, and there is evidence that endometrial cancer is sensitive

Popular Abstract in Swedish Den offentliga sektorn har vuxit drastiskt under det senaste århundradet och utgör idag en stor del av ekonomin i många västländer. Givet storleken på den offentliga sektorn och dess potentiella inflytande över såväl enskilda individer som samhälle är studier som dokumenterar effekterna av den offentliga sektorn värdefulla. Denna avhandling "Den Offentliga Sektorns BegrThe size of government has increased dramatically over the last century. Given the magnitude of government involvement in the economy and the potential influence it has on individuals as well as the economy, studies documenting the effects of government size may offer particularly timely insights. This thesis addresses some of these issues. Chapter two and three deal with welfare reform. Welfare

Background: Working memory is considered to influence a range of linguistic skills, i.e. vocabulary acquisition, sentence comprehension and reading. Several studies have pointed to limitations of working memory in children with specific language impairment. Few studies, however, have explored the role of working memory for language deficits in children with hearing impairment. Aims: The first aim

Popular Abstract in Swedish Det finns två etablerade sätt att beskriva zigenarnas historia i Sverige. Historien talar antingen om hur illa myndigheterna burit sig åt mot zigenare, eller så berättar historien om zigenarnas självvalda isolering. Gemensamt för beskrivningarna är påståendet att zigenare alltid varit desamma och uppvisar ett likartat levnadssätt genom historien. I denna avhandling studThis thesis analyses Swedish gypsy policy between 1880 and 1970, as part of a larger sociopolitical project undertaken by the Swedish authorities to promote social order and stability. During this period, the treatment of marginalized groups was shaped by the same visions and objectives as for the population as a whole. Gypsies in Sweden have been subject to the same regulations for as other poor

Testicular germ cell tumours (TGCT) exhibit remarkable ability to differentiate into virtually all somatic tissue types. In this study, we investigated changes in mucin-type O-glycosylation, which have been associated with somatic cell differentiation and cancer. Expression profile of simple mucin-type O-glycans (Tn, sialyl-Tn, T), histo-blood group H and A variants and six polypeptide Ga1NAc-tran

Based on a literature review and the SSG experience, the most important prognostic factors in high-grade osteosarcoma appear to be the presence of detectable metastases at diagnosis, tumour volume, old age, sex, histologic response, and possibly tumoral P-glycoprotein expression. However, for an adolescent patient with non-metastatic extremity disease, there is no consensus regarding prognostic fa

Popular Abstract in Swedish I denna avhandling beskrivs sambanden mellan funktion i centrala delar av näthinnan, och dess struktur, vid några valda ärftliga och förvärvade sjukdomstillstånd i näthinnan. Denna jämförelse är möjlig genom den relativt nya utvecklingen av multifokalt ERG (mfERG), med vars hjälp centrala näthinnans funktion kan bedömas, samt optisk koherens tomografi (OCT), med vilken In this thesis, retinal function in general, as well as central retinal function and structure are described in selected forms of acquired and hereditary retinal disorders, in order to improve our understanding of underlying pathogenic mechanisms. This comparison has been made possible during the last years, through the relatively recent development of multifocal ERG (mfERG) and optical coherence
