The purpose of this paper is to develop an approach to estimate peat accumulation rates (PAR) over recent decades based on the age and burial depths of roots from pine sapling and to use the newly developed approach to estimate spatial variations of PAR. To this end, we sampled 120 pine saplings growing in three plots at Rėkyva peatland in Lithuania and accounted for the microtopography around eac
In dry sandy soil, soil water is naturally redistributed by forces owing to matric and gravitational potential, and temperature gradients. Occurring shrub vegetation strongly influences these patterns by hydraulic redistribution within the soil. This means that plants can move water from moist to drier soil areas to extract nutrients from the drier soil and enhance nutrient uptake. This incorporat
Parkinson´s disease (PD) is one of the most common neurological diseases with both motor and non-motor symptoms that can be perceived as difficult to control despite medical treatment. This leads to several consequences in everyday life for example difficulties in activities of daily living (ADL), sometimes already at diagnosis. Therefore, rehabilitation is important to manage the consequences of
Increasing temperature trends are expected to impact yields of major field crops by affecting various plant processes, such as phenology, growth, and evapotranspiration. However, future projections typically do not consider the effects of agronomic adaptation in farming practices. We use an ensemble of seven Global Gridded Crop Models to quantify the impacts and adaptation potential of field crops
We present a mathematical model for the simulation of the development of an outbreak of COVID-19 in a slum area under different interventions. Instead of representing interventions as modulations of the parameters of a free running epidemic we introduce a model structure that accounts for the actions but does not assume the results. The disease is modelled in terms of the progression of viremia re
Background and purpose — Total knee arthroplasty (TKA) has increased substantially in Sweden. We quantified the relative risk for TKA in the Swedish population for different BMI categories and age groups to investigate whether the continued increase in TKA is attributable to increased prevalence of obesity and elderly people in the population, and to put forward model predictions for coming needs
Solceller är en eftertraktad teknik för att mildra de globala klimatförändringarna. Samtidigt finns det en växande oro att denna teknik är både skadlig för miljön och orättvist fördelad i världsekonomin. Forskare och miljöaktivister är oeniga i frågan om en global maktrelation är ofrånkomligt kopplad till solcellsteknik. Denna avhandling undersöker i vilken utsträckning de globala sociala och mateSolar photovoltaic (PV) technology is one of the most favored means of mitigating climate change. At the same time, there is a growing concern over how this technology is both environmentally harmful and unevenly distributed in the world economy. Researchers and environmentalists differ on whether a global relation of power is inherent in solar technology. This thesis investigates to what extent t
Traumatic brain injury (TBI) has been named the most complex disease in the most complex organ of the body. It is the most common cause of death and disability in the Western world in people <40 years old and survivors commonly suffer from persisting cognitive deficits, impaired motor function, depression and personality changes. TBI may vary in severity from uniformly fatal to mild injuries with
Purpose of ReviewThis review aims to summarize the evolution and recent developments in the classification of ANCA associated vasculitis (AAV) and to summarize evaluations of the 2022 ACR/EULAR classification criteria of AAV in several cohorts.Recent FindingsThe classification of AAV has been a field of controversy for some time. The parallel existence of classification criteria and disease defini
Exposure time to heat is increasing with climate change. Heat exposure thresholds are important to inform heat early warning systems, and legislation and guidance for safety in the workplace. It has already been stated that thresholds can be lower for vulnerable groups, including the elderly, pregnant women, children, and those with pre-existing medical conditions due to their reduced ability to t
roduction of biomass for bioenergy on marginal land has been promoted to decrease the use of non-renewable energy without competing with food production. Previous estimates of marginal land and abandoned farmland in Sweden available for bioenergy production are based on general statistics and assumptions but lack in-depth analyses of potential alternative land-use values. Easily accessible public
Collecting detailed hydrogeological data before, during, and after remediation campaigns is essential for effective management and monitoring of contaminated sites. As in-situ remediation injection treatment becomes more popular, recording the hydraulic response during these events offers an opportunity to collect detailed data on hydrogeological parameters. Often, multiple injections are performe
Aromatic polyamide films form the active layer in reverse osmosis desalination membranes. Despite widespread use of this technology, it suffers from low rejection rates for certain water contaminants and from membrane fouling. Through a better understanding of the fundamental surface chemical processes during reverse osmosis desalination, advances in membrane and material design are expected. The
This book examines how dukeship – the position of being a duke – was defined and negotiated in Sweden between the late 1550s and the early 1620s. The aim is to shed light on how the structural problem of royal spares, with dukes as pillars and perils of hereditary monarchy, influenced politics and the integration process of a ruling house. Through an institutional biography approach and a critical
Accurate and reliable estimation of actual evapotranspiration (AET) is essential for various hydrological studies, including drought prediction, water resource management, and the analysis of atmospheric–terrestrial carbon exchanges. Gridded AET products offer potential for application in ungauged areas, but their uncertainties may be significant, making it difficult to identify the best products
Background: Bariatric surgery is a standard treatment for severe obesity, but little is known about patients’ perceptions about the long-term impact of such surgery. Objective: The aim of this study was to explore patients’ experiences of living with a bariatric procedure for more than a decade. Setting: University hospital. Methods: At the 10-year follow-up after undergoing Roux-en-Y gastric bypa

The Earth’s magnetic field (or geomagnetic field) has been measured for hundreds of years, starting with maritime observations from logbooks for navigation purposes to present day real-time recording by satellites. From these records, the geomagnetic field variation throughout recent time is well-understood. In order to study longer term field variations (on the scale of hundreds to thousands of y
Agricultural expansion and intensification have boosted global food production but have come at the cost of environmental degradation and biodiversity loss. Biodiversity-friendly farming that boosts ecosystem services, such as pollination and natural pest control, is widely being advocated to maintain and improve agricultural productivity while safeguarding biodiversity. A vast body of evidence sh
Introduction: Unwanted glucose absorption during peritoneal dialysis (PD) remains a clinical challenge, especially in diabetic patients. Recent experimental data indicated that inhibitors of the sodium and glucose co-transporter (SGLT)-2 could act to reduce glucose uptake during PD, which raises the question of whether glucose absorption may also occur via intracellular or trans-cellular pathways.
