Pulmonary surfactant and drug delivery : Vehiculization of a tryptophan-tagged antimicrobial peptide over the air-liquid interfacial highway

This work evaluates interaction of pulmonary surfactant (PS) and antimicrobial peptides (AMPs) in order to investigate (i) if PS can be used to transport AMPs, and (ii) to what extent PS interferes with AMP function and vice versa. This, in turn, is motivated by a need to find new strategies to treat bacterial infections in the airways. Low respiratory tract infections (LRTIs) are a leading cause

Influence of nanostructure formation on the crystal structure and morphology of epitaxially grown Gd2O3 on Si(001)

The influence of growth conditions on the layer orientation, domain structure and crystal structure of gadolinium oxide (Gd2O3) on silicon (001) has been investigated. Gd2O3 was grown at low (250°C) and high (850°C) temperatures with different oxygen partial pressure as well as a temperature ramp up during growth. At low temperature, the cubic bixbyite type of crystal structure with space group Ia

Spontaneous Cell Cluster Formation in Human iPSC-Derived Neuronal Spheroid Networks Influences Network Activity

Three-dimensional neuronal culture systems such as spheroids, organoids, and assembloids constitute a branch of neuronal tissue engineering that has improved our ability to model the human brain in the laboratory. However, the more elaborate the brain model, the more difficult it becomes to study functional properties such as electrical activity at the neuronal level, similar to the challenges of

Density matrix renormalization group description of the island of inversion isotopes F 28-33

Background: Recent experiments have confirmed that the neutron-rich isotopes F28,29 belong to the so-called island of inversion (IOI), a region of the nuclear chart around Z=10 and N=20 where nuclear structure deviates from the standard shell model predictions due to deformation and continuum effects. However, while the general principles leading to the IOI are relatively well understood, the deta

Human-directed attachment behavior in wolves suggests standing ancestral variation for human–dog attachment bonds

Domesticated animals are generally assumed to display increased sociability toward humans compared to their wild ancestors. Dogs (Canis familiaris) have a remarkable ability to form social relationships with humans, including lasting attachment, a bond based on emotional dependency. Since it has been specifically suggested that the ability to form attachment with humans evolved post-domestication

Peatland Heterogeneity Impacts on Regional Carbon Flux and Its Radiative Effect Within a Boreal Landscape

Peatlands, with high spatial variability in ecotypes and microforms, constitute a significant part of the boreal landscape and play an important role in the global carbon (C) cycle. However, the effects of this peatland heterogeneity within the boreal landscape are rarely quantified. Here, we use field-based measurements, high-resolution land cover classification, and biogeochemical and atmospheri

Interfacial layer formation during the growth of Gd2O3 on Si(001) and its thermal stability

The thermal stability of monoclinic Gd2O3 grown on Si(001) as well as changes of the interfacial layer formed during the growth are investigated during rapid thermal annealing in nitrogen atmosphere between 600 °C and 1000 °C using x-ray diffraction and transmission electron microscopy (TEM). The monoclinic Gd2O3 layer was grown at 400 °C and oxygen partial pressure of 5 × 10−7 mbar. The Gd2O3 lay

Production of forward heavy-flavor dijets at the LHCb within the kT -factorization approach

We calculate differential cross sections for cc¯- and bb¯-dijet production in pp scattering at s=13 TeV in the kT-factorization and hybrid approaches with different unintegrated parton distribution functions (uPDFs). We present distributions in the transverse momentum and pseudorapidity of the leading jet, the rapidity difference between the jets and the dijet invariant mass. Our results are compa

How socio-technical regimes affect low-carbon innovation : Global pressures inhibiting industrial heat pumps in the Netherlands

This paper shows that the socio-technical barriers that sustainable innovations face, may stem from global regimes. Existing transitions approaches like the Technological Innovation System (TIS), overlook the impact of global regimes on radical innovation. Building on institutional theory, we therefore develop a theoretical framework that captures TIS-regime interaction, allowing us to analyze the

Relativistic Two-Photon Matrix Elements for Attosecond Delays

The theory of one-photon ionization and two-photon above-threshold ionization is formulated for applications to heavy atoms in attosecond science by using Dirac–Fock formalism. A direct comparison of Wigner–Smith–Eisenbud delays for photoionization is made with delays from the Reconstruction of Attosecond Beating By Interference of Two-photon Transitions (RABBIT) method. Photoionization by an atto

Toward Autonomous Production of mRNA-Therapeutics in the Light of Advanced Process Control and Traditional Control Strategies for Chromatography

mRNA-based therapeutics are predicted to have a bright future. Recently, a B2C study was published highlighting the critical bottlenecks of mRNA manufacturing. The study focused on supply bottlenecks of various chemicals as well as shortages of skilled personnel. The assessment of existing messenger ribonucleic acid (mRNA) vaccine processing shows the need for continuous manufacturing processes th

The development and certification of a single fuel high speed marine CI engine on methanol

Reducing emissions is a priority for all vessels, as global warming is accelerating, and emissionregulations are becoming ever stricter. Still, waterborne transport is the most energy efficientalternative in many cases, and in some cases the only alternative. Vessels in the maritime sectoroperate far from electric charging infrastructure, and have large demands in terms of autonomy, so tobe able t

Women in the public sphere in Egypt : 2011–2014

Through interviews, many documents and secondary data, this dissertation investigates how fifty-four women activists participated in the public sphere in Egypt from the outbreak of the 2011 uprising to the re-emergence of the authoritarian regime in 2014. The women activists studied in the dissertation took part in various counter-publics of social movements, opposition political parties, and civi

Complex Multiplicative Calculus and Mixed Problems

In this thesis we consider multiplicative integrals and derivatives on functions on the positive numbers, the logarithmic Riemann surface and the punctured complex numbers. Additive structures on the real and complex numbers are related to their multiplicative counterparts on the positive numbers and the logarithmic Riemann surface by defining exponential transition functors. We use a lift-project

Typological features of Telugu : defining the parameters of post-Talmian motion event typology

Recent research in motion event typology has moved beyond the binary Talmian division of "verb-framed" and "satellite-framed" languages and has established the existence of at least four distinct typological clusters, instantiated by, for example, Swedish (Germanic), French (Romance), Thai (Tai-Kadai) and Telugu (Dravidian). In this paper, we focus on characteristic features of Telugu, as a repres

Gröna obligationer i den svenska fastighetsbranschen - Hur påverkar EU:s taxonomi?

Under de senaste åren har gröna obligationer blivit ett populärt finansieringsalternativ bland många svenska fastighetsbolag. Obligationerna är finansiella instrument och fungerar som räntebärande skuldebrev med en förutbestämd löptid. Investerarna erhåller därmed avkastning i form av ränta och kan samtidigt vara säkra på att det investerade kapitalet används för klimat- och miljövänliga investeriIn recent years, green bonds have become a popular financing option among many Swedish real estate companies. Bonds are financial instruments and function as interest-bearing debentures with a predetermined term. The investors receive a return on capital in the form of interest and can at the same time be sure that the invested capital is used for climate and environmentally friendly investments b
