The building industry is continuously adapting to the changing needs and demands. The rise in emissions, depletion of resources and accumulating waste are some of the important problems that have to be addressed by architects all over the world today. In this context, the thesis addresses these problems through informed building material choices and exploring the potential of circular use of resou
Syftet med denna studie är att undersöka om körsång kan användas som ett verktyg för att motverka psykisk ohälsa bland ungdomar genom elevhälsan. Vidare undersöktes även huruvida körpedagoger ser fördelar med att beakta körsångens hälsoeffekter i sin egen undervisning, och hur möjligheten för att använda körsång inom elevhälsan i dagens gymnasieskola ser ut. För att genomföra studien gjordes tre kThe purpose of this study is to investigate if choir singing can be used as a tool to prohibit mental illness or bad mental health amongst youths through student health services. The study also investigates if choir teachers can see benefits of teaching choir with choir singings health effects in mind, and what the possibility is to use choir singing as a tool in today’s high schools (Swedish gymn
The sex-dependent effect of environmental conditions on nestlings has been extensively studied in size dimorphic birds. Whether males or females are more sensitive to poor conditions is not yet clear; however, the degree of sexual size-dimorphism, brood size and their interactions seem to influence the pattern. Much less is known about sex-dependent environmental sensitivity in size-monomorphic sp
Physical properties of aqueous solutions of hydrophobically modified crosslinked polyacrylic acids change quite extensively as the polymer is charged up. A study is carried out concerning the similarities between two polymer ionization processes, that is, by pH increment and anionic surfactant addition. The two processes charge the polymer by distinctly different mechanisms. At sufficiently high p
A more detailed mechanistic understanding of how low molecular weight (MW) carbon (C) substrates are mineralized within the rhizosphere by soil microbial communities is crucial to accurately model terrestrial C fluxes. Currently, most experiments regarding soil C dynamics are conducted ex-situ (laboratory) and can fail to account for key variables (e.g. temperature and soil water content) which va
High humidity, high ash content and low heating values are the major disadvantages of using lignite without ant pretreatment. High moisture content and low energy density make some of the biomass resources disadvantages in direct energy production. In this thesis, the main aims to reduce the disadvantages of both sources and obtain fuel with different structural/physical properties by hydrothermal
ObjectiveMost research on patient experiences of rheumatoid arthritis (RA) care is performed with patients who have established RA and less often with patients with early RA. Experiences of and expectations about health care may change over time, which is why the aim was to explore patients’ perceptions of person-centered care (PCC) early in the RA disease course.MethodsThirty-one patients with ea
Many workers are occupationally exposed to polycyclic aromatic hydrocarbons (PAHs), which may cause various health problems, and some PAHs are known or suspected carcinogens. PAH exposure is primarily monitored by air sampling, but contamination may also occur through dermal exposure. PAHs adsorbed to the skin can be sampled by tape-stripping, but subsequent extraction of sampling tapes in organic
In this study, the use of light sheet fluorescence microscopic imaging is demonstrated for viewing the dynamic of atomizing sprays with high contrast and resolution. The technique presents several advantages. First, liquid fluorescence gives a more faithful representation of the structure of liquid bodies, droplets, and ligaments than Mie scattering does. The reason for this is that the signal is
Background: Endoscopic submucosal dissection (ESD) is an advanced method allowing en bloc resection of large and complex lesions in colon and rectum. Herein, the European experience of colorectal ESD was systematically reviewed in the medical literature to determine the clinical efficacy and safety of colorectal ESD in Europe. Material and methods: A systematic search of PubMed for full-text studi
More than 50 irregular satellites revolve around Jupiter and more than 30 around Saturn. There, at least three collisional families were identified. Among these, the Himalia family of prograde irregular moons at Jupiter is characterised by a velocity dispersion of several hundred m/s, inconsistent with a collisional origin (Nesvorný et al., 2003). Here we investigate whether the dispersion could s
BACKGROUND: The majority of out-of-hospital cardiac arrests (OHCAs) occur at place residence, which is associated with worse outcomes in unselected prehospital populations. Our aim was to investigate whether location of arrest was associated with outcome in a selected group of initial survivors admitted to intensive care.METHODS: This is a post-hoc analysis of the Targeted Temperature Management a
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
Identification of genomic rearrangements by microarrays or short-read sequencing frequently lacks information about the exact architecture and breakpoints of variants due to technical limitations. Independent verification of complex structural variants (SVs) is often performed using custom targeted assays, making confirmation of clinically relevant findings time consuming and laborious. In this st
Background: Standardized definitions of autoimmune disease (AD) are lacking. Therefore, we aim to propose a definition of AD for register-based research and estimate the burden of AD in Sweden as registered in the National Patient Register (NPR) from 1980 to 2023. Methods: Leveraging the NPR, we defined AD as having at least two relevant International Classification of Diseases (ICD) codes represe
Objectives: SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss-of-function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes. Here we describe a novel dominant variant in SLC4A4 in patients wit
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a multifactorial disorder involving gut-brain axis dysregulation, altered barrier integrity, microbial imbalance, and stress-related mechanisms, with limited nutritional strategies targeting these pathways. Tannin-rich extracts may exert barrier-protective, microbiota-modulating, and stress-related effects. In a prospective before-after pilo
