Drought is predicted to increase in the future due to climate change, bringing with it myriad impacts on ecosystems. Plants respond to drier soils by reducing stomatal conductance in order to conserve water and avoid hydraulic damage. Despite the importance of plant drought responses for the global carbon cycle and local and regional climate feedbacks, land surface models are unable to capture obs
Nuclear technology and the use of radiation sources have been extensively adopted in the modern world. Despite that, a number of radiological accidents, significantly affecting population and the environment, has happened. Few of the most known are accidents in Chernobyl and Fukushima nuclear power plants. As a result, significant areas are still contaminated with some residential areas evacuated
Purpose: The purpose of this work was to establish an empirical model of the ion recombination in the Advanced Markus ionization chamber for measurements in high dose rate/dose-per-pulse electron beams. In addition, we compared the observed ion recombination to calculations using the standard Boag two-voltage-analysis method, the more general theoretical Boag models, and the semiempirical general
In Europe, willow (Salix spp.) trees have been used commercially since the 1980s at a large scale to produce renewable energy. While reducing fossil fuel needs, growing short rotation coppices (SRCs), such as poplar or willow, may have a high impact on local air quality as these species are known to produce high amounts of isoprene, which can lead to the production of tropospheric ozone (O3). Here
Lignin is the second most abundant biopolymer on Earth after cellulose, found in virtually all plantswhere it is responsible for rigidity, hydrophobicity and mineral transport. For a long time, it has been considereda waste in the paper production process and incinerated for its energy content. However, with the depletion ofcrude oil reserves, it has been found to have a large potential to become
The success of social movements is highly dependent on their sustainability, as in their efforts to produce meaningful change, they inevitably encounter oppressive dominant forces. With the advent of the social media era, scholarly research on collective action has acquired an additional dimension, bringing the role of their communicative constitution to the forefront of discussions. However, a de
Background: With the approval of disease-modifying treatments (DMTs) for early Alzheimer’s disease (AD), there is an increased need for efficient and non-invasive detection methods for cerebral amyloid-β (Aβ) pathology. Current methods, including positron emission tomography (PET) and cerebrospinal fluid (CSF) analysis, are costly and invasive methods that may limit access to new treatments. Plasm
Background: The water supply in the Gaza Strip, Palestine, has been unstable and under strain for decades, resulting in major issues with drinking water quality, reliability, and acceptability. In 2018, between 25% and 30% of Gazans did not have regular access to running water. The progressive deterioration of water infrastructure and concerns over the quality of piped water have resulted in a com
IMPORTANCE: Despite a global decline in the mortality rate of children younger than 5 years (the under-5 mortality rate), neonatal deaths continue to present a substantial challenge. The etiology behind deaths varies between the early and late neonatal periods as well as at later ages.OBJECTIVE: To decompose the under-5 mortality rate in 47 low- and middle-income countries into 8 age intervals, pr
BACKGROUND: Preventing infection in primary sutured perineal tears after childbirth is crucial to avoid systemic antibiotic use and potential complications from poor healing. This study aimed to investigate the efficacy of an antibacterial, triclosan-coated suture (VicrylPlus ®) in reducing infection in primary sutured childbirth-related perineal tears. METHODS: The PLUS study was a single-cente
Eye movements originally made during memory formation are often spontaneously reproduced during retrieval, even in the absence of visual input, directing gaze back to the locations where goal-relevant episodic information was previously encountered. This behavior, known as gaze reinstatement, is thought to support the reactivation of episodic content associated with those locations (e.g., Johansso
Packaging serves a lot of purposes, and would be hard to do without. Packaging protects the goods during transport, saves costs, informs about the product, and extends its durability. A transport package is required to be strong and lightweight in order to be cost effective. Furthermore, it should be recycled because of environmental and economical concerns. Corrugated board has all of these featu
Different tau biomarkers become abnormal at different stages of Alzheimer's disease, with CSF phospho-tau typically becoming elevated at subthreshold levels of tau-PET binding. To capitalize on the temporal order of tau biomarker-abnormality and capture the earliest changes of tau accumulation, we implemented an observational study design to examine longitudinal changes in Tau-PET, cortical thickn
Det här avhandlingsprojektet handlar om självmedvetande och hur det förhåller sig till medvetande i stort. Mer specifikt handlar det om jagupplevelse, känslan av att vara ett jag, och om denna känsla med nödvändighet finns med i alla våra upplevelser eller inte. Vad betyder det då att ha en känsla av att vara ett jag? Det kan betyda flera saker, exempelvis känslan av att vara samma person över tidThe present dissertation project concerns the relationship between self and consciousness. Specifically, it concerns the phenomenal sense of self and if this is a necessary component of all experience or not. What is it to have a sense of self? This can refer to several things, such as the sense of being a continuous person through time, the sense of having a body, the sense of being in control of
Background: Per- and polyfluoroalkyl substances (PFAS) have been suggested to contribute to the development of metabolic diseases such as obesity, diabetes and non-alcoholic fatty liver disease (NAFLD). However, evidence from epidemiological studies remain divergent. The aim of the present study was to evaluate associations between PFAS exposure and prevalent diabetes in a cross-sectional analysis
Importance Identifying early proteomic profiles in infants who develop severe retinopathy of prematurity (ROP) may reveal targets for preventive interventions to reduce retinal vessel loss and the subsequent risk of severe ROP. Objective To assess early longitudinal profiles of blood protein levels in preterm infants with or without severe ROP and the effect of arachidonic acid (AA) and docosahexa
PURPOSE: To estimate the effect of dexamethasone eye drops on the risk of progression from type 2 retinopathy of prematurity (ROP) to ROP requiring traditional treatments.DESIGN: Register-based cohort study.PARTICIPANTS: Preterm infants born before 30 weeks' gestation from 2015-2018 (control years) and from 2020-2021 (intervention years) registered in the Swedish Quality Register for ROP at 4 Swed
Influenza A virus (IAV) is a major respiratory pathogen, causing around 650,000 deaths annually. Asignificant transmission pathway for IAV is via expelled respiratory aerosol. For successfultransmission via the aerosol route, IAV must remain infectious following transport from an infectedhost to a susceptible individual. Many environmental factors may affect IAV infectivity, includingambient relat
The drought of 2003 was exceptionally severe in many regions of Europe, both in duration and in intensity. In some areas, especially in Germany and France, it was the strongest drought for the last 50 years, lasting for more than 6 months. We used continuous carbon and water flux measurements at 12 European monitoring sites covering various forest ecosystem types and a large climatic range in ord
