A simple mass balance model has been developed to assess the planetary boundary for P supply in relation to use by human society. Phosphorus sources used by humans are from fossil reserves. The model takes into account resource use rate and reserves, consumption, phosphate to food production, environmental degradation, waste and recycling. Various policy scenarios are tested from current end of pi
Arktis står inför stora förändringar i samband med rådande klimat- och miljöförändringar, där de arktiska kusterna är utsatta. Förändringar i temperatur, havsnivå, stormar och havsisens utbredning är några av de faktorer som spelar in i hur kusterna och stränderna kan förändras. Syftet med studien är att först översiktligt se vilka kustmorfologiska förändringar som sker i Arktis idag och huruvida The Arctic is facing great changes due to current climate changes, where the Arctic coasts are especially vulnerable. Changes in temperature, mean sea level, storms and sea ice extent are some of the factors that shape how the coasts and beaches can be changed. The purpose of this study is firstly to examine what changes the Arctic coasts are experiencing today and whether they can be correlated t
This paper is based on a new procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints. The new procedure is motivated by the challenges of output feedback control design for the 3-state Moore-Greitzer compressor model. First, we use conditions for stability of a transformed system and the associated matching conditions to find the data of the st
Denna studie undersöker vilka motiv Lunds kommun framhåller bakom beslutet att anlägga spårvägen i Lund samt hur spårvägen framställs i relation till hållbar stadsutveckling och utvecklingen av stadsdelen Brunnshög. Syftet är att se hur planering av storskaliga infrastrukturprojekt kan ses som en bidragande faktor till attraktionskraft och identitet samt ur ett tillgänglighets- och rättviseperspekThis study examines the motives put forward by the Municipality of Lund behind the decision to construct the tramway in Lund. Framed in relation to sustainable urban development and the emergence of the Brunnshög district, the purpose of this project is to understand how the planning of large-scale infrastructure projects can be analyzed through perspectives of accessibility and justice, as well a
A search for R-parity-conserving supersymmetry in events with large missing transverse momentum, jets and at least one hadronically decaying τ-lepton is presented. Both gluino and squark pair production are considered, with the cascade decay of each gluino or squark producing either a τ-slepton or a τ-sneutrino. Three channels are examined, requiring either exactly one hadronically decaying τ-lept
Computer simulation can provide valuable insight into the forces driving biomolecular liquid-liquid phase separation. However, the simulated systems have a limited size, which makes it important to minimize and control finite-size effects. Here, using a phenomenological free-energy ansatz, we investigate how the single-phase densities observed in a canonical system under coexistence conditions dep
Background How does genetic liability to suicide attempt (SA), suicide death (SD), major depression (MD), bipolar disorder (BD), schizophrenia (SZ), alcohol use disorder (AUD), and drug use disorder (DUD) impact on risk for SA and SD? Methods In the Swedish general population born 1932-1995 and followed through 2017 (n = 7 661 519), we calculate family genetic risk scores (FGRS) for SA, SD, MD, BD
Introduction: Ethiopia has one of the largest number of adolescents living with HIV (ALHIV). As these adolescents reach adulthood they need to transfer from pediatric to adult-oriented clinics. Clear implementation guidelines for transition are lacking and factors associated with successful transition are inadequately investigated. Our objective was to describe the rate and age of transition from
In situ CO2 and CO measurements from five Integrated Carbon Observation System (ICOS) atmosphere stations have been analysed together with footprint model runs from the regional Stochastic Time-Inverted Lagrangian Transport (STILT) model to develop a dedicated strategy for flask sampling with an automated sampler. Flask sampling in ICOS has three different purposes, namely (1) to provide an indepe
The formation of biomolecular condensates inside cells often involve intrinsically disordered proteins (IDPs), and several of these IDPs are also capable of forming dropletlike dense assemblies on their own, through liquid-liquid phase separation. When modeling thermodynamic phase changes, it is well known that finite-size scaling analysis can be a valuable tool. However, to our knowledge, this ap
Objective: To describe the development and evaluation of the content and face validity and test-retest reliability of a disease-specific questionnaire that measures patient-reported outcomes and experiences for the Swedish National Diabetes Register for adult patients who have type 1 or type 2 diabetes. Methods: In this methodological study, a questionnaire was developed over four phases using an
We use Markov state models (MSMs) to analyze the dynamics of a β-hairpin-forming peptide in Monte Carlo (MC) simulations with interacting protein crowders, for two different types of crowder proteins [bovine pancreatic trypsin inhibitor (BPTI) and GB1]. In these systems, at the temperature used, the peptide can be folded or unfolded and bound or unbound to crowder molecules. Four or five major fre
Time-dependent ensemble averages, i.e., trajectory-based averages of some observable, are of importance in many fields of science. A crucial objective when interpreting such data is to fit these averages (for instance, squared displacements) with a function and extract parameters (such as diffusion constants). A commonly overlooked challenge in such function fitting procedures is that fluctuations
PURPOSE: To validate ironload T2* by automatic inline Maximum Likelihood Estimate (MLE) with k-space Rician noise correction, against the manual and automated truncation, as well as offset methods, in phantoms and in heart and liver in patients.METHODS: Twenty-five patients and an iron-oxide phantom were scanned at 1.5T using 2 multi-echo gradient-echo sequences. All parameters were identical (vox
The current study aims to computationally evaluate the effect of right upper arm position on the geometric and hemodynamic characteristics of the brachial artery (BA) and cephalic vein (CV) and, furthermore, to present in detail the methodology to characterise morphological and hemodynamical healthy vessels. Ten healthy volunteers were analysed in two configurations, the supine (S) and the prone (
Rhythmic patterning is a widespread structural trait of animal (including human) communication. Concomitantly, a key role of communication is to convey and/or induce emotion. The expression and modulation of emotion is also hypothesized to be a key mechanism for the evolution of rhythmic synchronization in humans. Despite the centrality of both rhythm and emotion to human and nonhuman communicatio
This study analyzes the transition to mechanized forest management and the implementation of sustainable-yields forestry in Sweden during the 1950s and 1960s. The objective is to produce insights that are relevantfor policymakers working with forests and the climate transition today. The analysis focuses on how the Swedish National Association of Forest Owners’ Associations (SSR)—an association or
