Loss of soil organic carbon (SOC) from farmland is a key threat to the capacity of soils to provide ecosystem services and exacerbates climate change. In alignment with a published protocol, we conducted a review and meta-analysis of time series of SOC measurements in long-term agricultural experiments to study absolute SOC changes under different agricultural management regimes. Our results show
Background: Intra- and interfractional variations in anatomy can cause unplanned substantial alterations of the dose distribution of the target in proton therapy. Motion management methods might be used in order to minimize anatomical variations. In the proton therapy of lung cancer, a potential motion management technique is the use of the voluntary breath-hold approach. The aim of this study was
We find ourselves in the midst of a remarkable technological revolution, with rapid advancements in fields such as artificial intelligence, robotics and information technology. Consequently, there is a pressing need for low-power technologies that are not reliant on continuous power supply. The field of spintronics aims to resolve this by coupling electric and magnetic properties. To pave the way
In the spring of 2015, five young feminist activists were arrested by the Chinese police for allegedly ‘causing trouble’, which resulted in global attention aimed at this new wave of feminist movement. Youth feminist activism have made their voice heard in China through numerous actions for gender equality since 2012. Not much is known about the new feminist movements and the limited work that exi
To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. As the research shows that the surface of a nanoparticle
Larvae from the non-biting midge family Chironomidae have previously been demonstrated to be sensitive to environmental pollution in aquatic environments. Exposure to different contaminants has resulted in an increasing occurrence of deformities of the mouthparts in the larvae. Common pollutions which induce mouthpart deformitys are metals (such as Pb, Zn, Cd, Cu, Hg, Cr, Ni), pesticides and some
High-order harmonic generation (HHG) is a highly nonlinear optical process in which extreme ultraviolet (XUV) radiation is generated due to the interaction of an intense laser field with atoms. This process enables the production of high harmonics, which would not be achieved with standard nonlinear media. The utilization of two-color laser fields (formed by combining a fundamental field with one
I och med elektrifieringen av energisektorn ställs höga krav på ökad inhemsk produktion av elektricitet i Sverige. På grund av den nuvarande fördelningen, där en stor del av produktionen sker i norra Sverige medan konsumtionen är koncentrerad till södra delarna av landet, är behovet extra stort i elområde 4 (SE4). Ett län som möter extra stora utmaningar är Skåne där självförsörjningsgraden för elThe current electrification of the energy sector puts high demands on increasing domestic electricity production in Sweden. This issue is enhanced by the current regional imbalance between supply and demand, while a major share of electricity generation is located in northern Sweden, consumption is concentrated in the south. Consequently, the need for new production is particularly great in electr
Many Swedish multifamily buildings from the 1960s are now reaching a stage where major renovation is needed to improve energy performance, indoor environmental quality, and long-term climate performance. At the same time, renovation strategies may involve trade-offs between operational energy savings, embodied carbon, thermal comfort, and material circularity. This thesis evaluates energy-efficien
The purpose was to investigate "adult foster childrens" view on their childhood and how it may have been influencing their adulthood. The importance of relationships were mostly in focus in the essay. The method was qualitative deepinterviews with three adult foster children between 30-42 years of age. Important themequestions was about: origin family, the time in foster home, relations
We have done a study concerning young women, in the ages of 20 to 30, and their thoughts about, consumption of, and habits regarding alcohol. The study is the base of our essay which has been done during the last ten weeks of the sixth semester (of seven) for the Bachelor degree of Social Work Science at Socialhögskolan in Lund. The study is built around five themes found in the essays purpose. El

Cerebral accumulation of amyloid-β is thought to be the starting mechanism in Alzheimer's disease. Amyloid-β can be detected by analysis of cerebrospinal fluid amyloid-β42 or amyloid positron emission tomography, but it is unknown if any of the methods can identify an abnormal amyloid accumulation prior to the other. Our aim was to determine whether cerebrospinal fluid amyloid-β42 change before am
IntroductionBeta-lactam antibiotics are essential in the treatment of Gram-negative bloodstream infections. The effect of beta-lactam antibiotics depends on the time of unbound antibiotic concentration above the minimal inhibitory concentration (MIC). An antibiotic concentration above MIC during the whole dosing interval (100% ƒT > MIC) has been suggested as a target for severe infections. The aim
Metal fuels can be promising candidates as alternative energy sources and renewable energy carriers within the metal-fuel cycle. They feature high energy density, low environmental impact, and broad production and application. One challenge in metal particle combustion lies in its multi-physics complexity compared to traditional hydrocarbon fuels. This thesis intends to investigate the combustion
This thesis comprises three self-contained chapters that explore how individual behavior, incentives, and institutional frameworks shape the allocation of scarce resources, with particular emphasis on healthcare markets. The first chapter examines the impact of intrinsic truth-telling preferences on consumer welfare within a priority pricing mechanism, in which individuals can gain faster access t
Objectives: To identify characteristics of older adult emergency department (ED) patients aged ≥65 with suicidal ideation and/or behavior. Methods: A single center retrospective chart review analyzed 392 patients (≥65) with suicidal ideation and/or behavior (2013–2019). Comprehensive full-text searches were used. Subgroup analyses for age and gender were conducted. Results: Depressive disorder was
Background: SARS-CoV-2, the causal agent of COVID-19, enters human cells using the ACE2 (angiotensin-converting enzyme 2) protein as a receptor. ACE2 is thus key to the infection and treatment of the coronavirus. ACE2 is highly expressed in the heart and respiratory and gastrointestinal tracts, playing important regulatory roles in the cardiovascular and other biological systems. However, the gene
The thesis presented here delves into why dwell time delays for commuter trains occur, with a specific focus on the impact of boarding and alighting passengers. The overarching aim is to develop knowledge of how time delays arise to identify and describe potential ways in which dwell time delays can be reduced. In addition to this, a secondary aim is to identify how dwell times can be studied on a
