During the spring of 2020 the world was hit by the Covid-19 pandemic which led to unpredicted and interesting effects in the domestic tourism sector. As a result of travel restrictions and social distancing recommendations there was an increase in visitors to national parks, hiking trails and other recreational areas in Sweden. The amount of visitors to the High Coast trail located in the east of
An increase of dissolved organic carbon (DOC) from rivers into coastal waters has been observed in previous studies, leading to an increase in hypoxic zonesin coastal areas when the bioavailable fraction of the DOC is degraded causing harm to ecosystems and negatively affecting ecosystem services vital for society. The first part of this study investigates if constructed wetlands can be used a
The transport sector is responsible for a third of Swedens’ total GHG emissions, where the private cars are a large part of this. Sweden is committed to reducing the emissions from the transport sector with 70 % until the year 2030. Shifting the vehicle fleet to electrical will be one important factor in achieving the goal, but such technical innovation will not be enough. To reach a more sust
The agricultural sector is both affecting and affected by climate change. Future climate is predicted to be warmer and wetter with more weather extremes. This is going to affect the already vulnerable agricultural sector and we need to strengthen our food production and food security. Therefore, agriculture needs to adapt to climate change to prevent negative effects but also to utilize the p
Increased carbon sequestration in agricultural land is an important measure to reduce global warming. Since the soil is a large carbon sink, a small change in the soil organic carbon (SOC) stocks can make a substantial difference to the carbon dioxide content in the atmosphere. An increase in SOC improves the soil health and fertility which in turn gives better yields and a more secure food supply
The degradation of ecosystems and the loss of biodiversity occurs at an alarming rate. This results in an imbalance of ecosystem functions, leading to a loss of ecosystem services. Ecosystem services are benefits which humans can derive from ecosystems and their internal processes, thus vital to preserve from a societal perspective. The purpose of this study was to explore the possibilities for
Climate change is a global threat to human and animals’ well-being on Earth. The threat of climate change has been known for over 30 years and it is now a fact that humans are the main contributing factor to it. Despite this, in 2022 it is no longer an abstract phenomenon, but our reality. One of the reasons why so little has been done to save the environment is people’s lack of or insufficient kn

Migratory birds have evolved a multitude of physiological and behavioural adaptations to reach their population-specific wintering areas during their first migration. The endogenous program encodes distance, direction and fuelling, and involves species-specific adaptations leading naïve migratory birds along highly diverse routes. While daylength has been extensively studied in relation to the ons
The double quantum coherence (DQC) signal in nonlinear spectroscopy gives information about the many-body correlation effects not easily available by other methods. The signal is short-lived, consequently, a significant part of it is generated during the pulse overlap. Since the signal is at two times the laser frequency, one may intuitively expect that the pulse overlap-related artifacts are filt
Purpose: The aim of this study was to develop and validate an artificial intelligence (AI)-based method using convolutional neural networks (CNNs) for the detection of pelvic lymph node metastases in scans obtained using [18F]PSMA-1007 positron emission tomography-computed tomography (PET-CT) from patients with high-risk prostate cancer. The second goal was to make the AI-based method available to
Purpose: Consistent assessment of bone metastases is crucial for patient management and clinical trials in prostate cancer (PCa). We aimed to develop a fully automated convolutional neural network (CNN)-based model for calculating PET/CT skeletal tumor burden in patients with PCa. Methods: A total of 168 patients from three centers were divided into training, validation, and test groups. Manual an
Objective: To assess the relationship between acetabular dysplasia (AD) and the risk of incident and end-stage radiographic hip osteoarthritis (RHOA) over 2,5,8 and 10 years. Design: Individuals (n = 1002) aged between 45 and 65 from the prospective Cohort Hip and Cohort Knee (CHECK) were studied. Anteroposterior pelvic radiographs were obtained at baseline and 2,5,8, and 10-years follow-up. False

In the Subarctic mountain birch (Betula pubescens ssp. czerepanovii) forest (SMBF) in Northern Fennoscandia, outbreaks by the geo
Knowledge about the past, current and future distribution of the human population is fundamental for tackling many global challenges. Censuses are used to collect information about population within a specified spatial unit. The spatial units are usually arbitrarily defined and their numbers, size and shape tend to change over time. These issues make comparisons between areas and countries difficu
Objectives: There are several breast cancer (BC) risk factors—many related to body composition, hormonal status, and fertility patterns. However, it is not known if risk factors in healthy women are associated with specific mammographic features at the time of BC diagnosis. Our aim was to assess the potential association between pre-diagnostic body composition and mammographic features in the diag
Today, atomic layer deposition (ALD) has become a firm corner stone of thin film deposition technology. The microelectronics industry, an early adopter of ALD, imposes stringent requirements on ALD to produce films with highly defined physical and chemical properties, which becomes even more important as device and component dimensions decrease. This, in turn, means that our understanding of the c
