Marine pollution is an increasingly serious environmental problem. Close to half of the total marine pollution comes from vessels and the pollutant that is the most obvious is oil. Fortunately, this problem has been recognized almost all over the world. Vessel-source oil pollution has attracted large numbers of international legislation, as well as national. As we will see in this paper, it often
The auditor is seen as the guardian of the market. However, several scandals have resulted in the public’s suspicions of auditor ethics. Therefore, the need of investigation of ethical awareness and ethical judgment among auditors should be taken into a deep consideration. The aim of this thesis is to investigate the differences in ethical awareness and ethical judgment of auditors across nations,
The purpose of this thesis was to examine how fasteners for mobile phone housing in metal sheet could be designed. The assignment was defined by Sony Ericsson Mobile Communication and the work was done in close cooperation with them. Sony Ericsson has had metal in their covers before but only as a cosmetic layer, the bearing parts have been made in moulded plastic. The reason to make a cover where
This paper assesses the communication and the use of climate scenarios at the science–science and science–policy interface in Finland, Sweden and Norway. It is based on document analysis and stakeholder questionnaires. The questionnaires targeted three stakeholder groups, all engaged in the communication and the use of climate scenario information: climate scenario producers; impact, adaptation an
A causal inference framework was developed to investigate crop responses to agricultural drought by integrating meteorological data, Sentinel-2-derived data, and soil property maps. To account for crop rotation, soil, and topographical variables, propensity score matching was employed to estimate drought-induced yield losses at the field level for selected periods. The Plant Phenology Index (PPI)
Background: To investigate a patient-level single imputation approach for patient reported outcomes (PROs) that express similar contents or associated PROs, where a PRO whose value is missing at a particular timepoint is substituted by another PRO whose value is available at the same timepoint. Methods: We performed a simulation study on registry-based spondyloarthritis data to explore the potenti
Background: It is unclear whether thyroid hormone levels are associated with the risk of mortality, cardiovascular disease (CVD) events, or cancer in men with normal TSH. Objectives: We analyzed if serum free T4 (FT4) or TSH is associated with the risk of mortality, incident CVD events, or cancer in Swedish men. Methods: Elderly men (n = 1801; mean age 75 years) in the Gothenburg and Malmö subcoho
Patients with chronic lymphocytic leukemia (CLL) have an impaired response to vaccination, which calls for improved vaccination strategies. This study aimed to evaluate antibody persistence 5 years after pneumococcal vaccination and response to revaccination. Seventy-four CLL patients and 31 controls, all primary immunized with 13-valent conjugated pneumococcal vaccine (PCV13) or 23-valent polysac
Aims: Individuals with type 1 diabetes (T1D) are typically diagnosed at a young age and exposed to lifelong hyperglycaemia. Despite improved metabolic control, the risk of vascular complications remains challenging. However, some individuals remain free from developing major diabetic complications even after long duration, so-called “escapers”. This study investigated transcriptomic biomarkers lin
Zircons from anatectic melts of the country rocks of three Proterozoic mafic-ultramafic intrusions from the Sveconorwegian Province in SW Sweden were microanalyzed for U-Th-Pb and rare earth elements. Melting and interaction of the wall rocks with the intrusions gave rise to new magmas that crystallized zircon as new grains and overgrowths on xenocrysts. The ages of the intrusions can be determine
This paper describes a measurement of the jet radius dependence of the dijet momentum balance between leading back-to-back jets in Formula Presented of Formula Presented collisions collected in 2018 and Formula Presented of Formula Presented collisions collected in 2017 by the ATLAS detector at the LHC. Both datasets were collected at Formula Presented TeV. Jets are reconstructed using the anti-Fo
Purpose: To define the curriculum content for two interactive learning courses on age-related macular degeneration (AMD): (1) an advanced course tailored for general ophthalmologists and (2) a basic course for non-ophthalmologist healthcare staff. This initiative aims to establish a national consensus on the educational framework for AMD management among general ophthalmologists in Denmark. Method
In this work, we investigate the cryogenic performance of hafnia-based ferroelectric capacitors with and without an aluminum oxide (ALO) interlayer, comparing conventional metal-ferroelectric-metal (MFM) structures to metal-ferroelectric-insulator-metal (MFIM) counterparts. Devices employing Hf0.5Zr0.5O2 as the ferroelectric layer were characterized from 300 K down to 10 K, targeting temperature r
One of the major recent breakthroughs has been the discovery of the last major merger to happen in the history of the Milky Way. Around 10 Gyr ago, the galaxy Gaia Enceladus with an estimated ∼10% of the Milky Way mass, fell into the potential of our Galaxy, bringing a large amount of stars that can be identified through their unique chemical and kinematic signatures. Simulations have long predict
Multi-wavelength thermo-optical analysis (MW-TOA) and Raman spectroscopy are commonly used methods to study soot sampled on filters, in terms of carbon content, nanostructure, and absorption properties. In this work, these techniques were combined to study how these characteristic properties of soot change in premixed flames, 1) at various flame heights during soot maturation and 2) as a result of
The updated Consolidated Health Economics Evaluation Reporting Standards, CHEERS 2022, is considered the most comprehensive publication to assess reporting quality of economic evaluations (EEs) incorporating criteria of trial- and model-based studies, including emerging methods. However, it holds multiple criteria per item without clear decision rules on minimum requirements for complete reporting
Med nya läkemedel, hudvårdsprodukter, stekpannor och bekämpningsmedel följer också att allt fler föroreningar släpps ut i naturen via bland annat jordbruk samt avlopp från industrier och sjukhus. Dessa föroreningar sprids till våra vattendrag, påverkar de organismer som lever där negativt och kan även förorena vårt dricksvatten. Ett läkemedel som släpps ut i naturen och som kan ses som särskilt pOrganic contaminants are present in aquatic environments and there is a need for water treatment techniques that are both efficient and practically implementable. Antibiotics are particularly problematic organic contaminants, as insufficient removal can contribute to the spread of antibiotic resistance, which can affect essential bacteria for ecosystems and cause untreatable infections in humans.
Background: We aimed to determine corticosteroid (CS) use in paediatric inflammatory bowel disease (PIBD, < 18 years), which remains common despite recommendations for limited use and the emergence of steroid-sparing therapies. Methods: We conducted a study of all children in Sweden diagnosed with CD (n = 2460) or UC (n = 2470) in 2006–2022. Nationwide health registers provided annual individual-l
Vad händer med den kirurgiska förmågan när man sänker bildfrekvensen? En studie för utveckling av autonoma kirurgiska robotar med människan som utgångspunkt. Varje år föds cirka 1.3 miljoner barn med hjärtfel och cirka 25% behöver vård inom ett år för att överleva. Då det råder global brist på barnhjärtkirurger, hinner inte alla barn få den vård de behöver. Det kan dessutom ta en kirurg 15-20 år A shortage of pediatric heart surgeons across the world limits the available surgical interventions, leading to long wait times and higher risk of mortality. The use of robotic surgery and its advantages may help address this issue, and the Collaborative Articial Intelligence Sur- gical Assistance-project is a starting point to develop an autonomous robotic surgical assistant. However, the video f
