This paper focuses on mixing strategies to enhance the growth of microalgae in a raceway pond. The flow is assumed to be laminar and the Han model describing the dynamics of the photosystems is used as a basis to determine growth rate as a function of light history. A device controlling the mixing is assumed, which means that the order of the cells along the different layers can be rearranged at e
We present a coupled model describing growth of microalgae in a raceway cultivation process, accounting for hydrodynamics. Our approach combines a biological model (based on the Han model) and shallow water dynamics equations that model the fluid into the raceway. We then describe an optimization procedure dealing with the topography to maximize the biomass production over one lap of the raceway.
Biosensors represent a promising approach for rapid therapeutic drug monitoring (TDM) of β-lactam antibiotics. However, no single biosensor strategy has yet been established to cover all four major β-lactam classes: penicillins, cephalosporins, carbapenems, and monobactams. Recently, an enzyme thermistor biosensor using New Delhi metallo-β-lactamase-1 (NDM-1) as the biorecognition element enabled
Understanding surfactant self-assembly in deep eutectic solvents (DES) is fundamentally challenging, and computational efforts for in silico screening are frequently hampered by the computational expense of all-atom simulations. To circumvent these limitations, we present newly parameterized and rigorously validated coarse-grained Martini 3 models for the cetyltrimethylammonium (CTA) cation and gl
Skattelagstiftningen i Sverige och Europeiska unionen utformas i allt större utsträckning med utgångspunkt i dokument som tagits fram av OECD. Modellregler, kommentarer och administrativa riktlinjer om skattebaserodering och vinstförflyttning samt global minimibeskattning är inte rättsligt bindande, men påverkar ändå innehållet i bindande rätt. I avhandlingen undersöks vilket rättskällevärde sådanTax legislation in Sweden and in the European Union is increasingly drafted with reference to documents produced by the OECD. Model rules, commentaries and administrative guidance concerning base erosion and profit shifting and global minimum taxation are not legally binding, yet they influence the content of binding law. This thesis examines what weight such documents can be accorded as sources o
This article deals with the embodied and sensory experiences of individuals in Iceland who have become vegan in recent years. Grounded in ethnology and theoretically informed by embodied and relational approaches to eating, the study employs the concept of attunement to analyze empirical material from in-depth interviews with eighteen vegans aged 21–63 years old, as well as thirty-five written resThis article deals with the embodied and sensory experiences of individuals in Iceland who have become vegan in recent years.

Sustainability in agriculture is as much a policy goal as a cultural and political project: privileging scientific expertise, innovation, and entrepreneurship, it defines what counts as competent farming, sidelining the everyday, hands-on skills that actually sustain it. This paper examines how skills shape sustainability in Southeastern European agriculture, focusing on North Macedonia and Greece
Hybrid desalination processes have gained attention for overcoming limitations of conventional membrane desalination. Forward osmosis (FO) systems using thermo-responsive polymer draw solutions are considered promising. In this work, the feasibility for water recovery from a thermo-responsive block copolymer solution (PAGB2000) was investigated using pervaporation (PV) and nanofiltration (NF) memb
In response to increasing human pressures on biodiversity, conservation targets have been set to reduce these pressures and halt biodiversity decline. However, consequences of these objectives on common species are rarely studied. We analyse the effect of a range of drivers related to climate, land use and land-use intensity on 265 common bird and 144 common butterfly species from more than 20,000
Semiconductor heterostructures that combine components with different dimensionalities provide an interesting avenue to manipulate the physical properties of the resulting material. Two-dimensional lead halide perovskites crystallize as flat microcrystals and have efficient in-plane exciton mobility, while perovskite nanocrystals are efficient emitters with a tunable bandgap that can self-ass
Retaining glycosyltransferases catalyze the formation of stereochemically conserved glycosidic bonds through mechanisms that remain debated. Using bovine α1,3-galactosyltransferase (α3GalT) as a model, we combine mutagenesis, equilibrium unfolding, kinetics, and molecular dynamics simulations to understand how donor-induced loop ordering promotes catalysis. Alanine-scanning mutagenesis of the C-te
The development of stable, high-concentration oil-in-water nanoemulsions (NEs) incorporating thyme essential oil (TEO) is hindered by intrinsic instability mechanisms, such as Ostwald ripening, and by challenges in characterizing concentrated, optically complex systems. Here, a rational, inquiry-driven formulation strategy, aligned with Formulation by Design principles, was applied to produce NEs
Oven bags are widely used in cooking to improve food juiciness and flavor while minimizing dishwashing. These bags are commonly manufactured from plastics such as polyamide (PA, nylon) and polyethylene terephthalate (PET). However, plastics used in food preparation may release additives, microplastics, or nanoplastics into food during heating, raising potential environmental and health concerns. T
Palladium hydrides are promising systems for hydrogen sensors and hydrogen storage, making the study of hydride formation in nanoparticles highly relevant. Lately, such studies have often been performed in situ or operando using synchrotron radiation of increasingly high intensity and brilliance. While beam-induced effects are well documented in liquid environments, they are rarely considered in t
This dissertation examines rhetorical aspects of market-oriented political thought in Sweden during the turn towards market-liberalism during the 1970s and 1980s. While there is a vast body of literature that demonstrates the importance of employers’ organisations in the dissemination of market-liberal ideas in Sweden, less attention has been paid to the rhetorical aspects through which ideologica
We report on the development and first experiments at a new X-ray absorption spectroscopy (XAS) endstation at the FemtoMAX beamline of the MAX IV Laboratory. Femtosecond time-resolved XAS measurements on solvated photoexcited molecular systems were performed with pulse-width-limited temporal resolution. The results demonstrate nearly shot-noise-limited signal quality, highlighting the capability o
Aim: We aimed to investigate the prevalence of self-reported kinesiophobia seven months after out-of-hospital cardiac arrest (OHCA) and its relationship with self-reported and objectively assessed physical activity. Additionally, to explore the relationship between self-reported kinesiophobia and symptoms of anxiety and depression.Method: Cross-sectional sub-study conducted within the Targeted HypAim: We aimed to investigate the prevalence of self-reported kinesiophobia seven months after out-of-hospital cardiac arrest (OHCA) and its relationship with self-reported and objectively assessed physical activity.

The internal structures of the semi-magic, neutron-rich N=126 nuclei, 203Ir and 202Os, were studied. The nuclei of interest were produced using relativistic-energy projectile fragmentation of a 208Pb beam at the GSI facility in Germany. Internal isomeric decays were investigated via delayed γ-ray spectroscopy. In 203Ir, four observed transitions were associated with parallel decay branches from an
