Microplastics and nanoplastics (MNPs) are ubiquitous environmental pollutants with increasing implications for human health. While their presence in human tissues is established, the molecular mechanisms driving their potential neurotoxicity remain unclear. This study investigates the impact of polystyrene (PS) on amyloid protein misfolding and cellular metabolism using optical photothermal infrar

Control of crystallographic texture is key to improving the properties of piezoelectric ceramics, but it has so far mainly been realized in the form of fiber textures perpendicular to the dominant surface of simple 2.5D structures. This work demonstrates how grains in piezoelectric ceramics can be aligned in complex patterns and shapes via material extrusion-based additive manufacturing, specifica

Pyrolytic carbon derived from thermosetting polymer precursors is a promising electrode material for bioelectrochemical applications due to its structural robustness, chemical stability, biocompatibility, and amenability to surface modification. Crucially, it allows the integration of diverse nano- and microstructures on the electrode surface. In this study, we introduce pyrolytic carbon nanograss

The accepted picture of the structure of a micelle in solution arises from the idea that the surfactant molecules self-assemble into a spherical aggregate, driven by the conflicting affinity of their head and tail groups with the solvent. It is also assumed that the micelles size and shape can be explained by simple arguments involving volumetric packing parameters and electrostatic interactions.

We have previously reported that robust mesostructured films will grow at the surface of alkaline solutions containing cetyltrimethylammonium bromide (CTAB), polyethylenimine (PEI), and silica precursors. Here we have used time-resolved small-angle X-ray scattering to investigate the structural evolution of the micellar solution from which the films form, at several different CTAB-PEI concentratio

Given their flexibility and encouraging performance, deep-learning models are becoming standard for motion prediction in autonomous driving. However, with great flexibility comes a lack of interpretability and possible violations of physical constraints. Accompanying these data-driven methods with differentially-constrained motion models to provide physically feasible trajectories is a promising f

To achieve high thermal efficiencies, 30 percent and higher, for small gas turbines a recuperator is mandatory. As the recuperator represents 25–30 percent of the overall machine cost, efforts are now being focused on establishing new low-cost recuperator concepts for gas turbine engines. In this paper the cross corrugated (CC), also called chevron pattern, heat transfer surface is reviewed to ass

Abstract in UndeterminedIn this paper, different multivariate statistical approaches for analysing wastewater treatment process data are presented and compared. For this purpose, all the methods have been tested using one-year operational data in a simulation model benchmark. The general monitoring strategy adopted includes a screening stage to improve data quality, all adaptive model to detect an

Some raw material characteristics were evaluated in three apple varieties cultivated in Southern Sweden, namely Kim, Mutsu and Jonagold. The study was undertaken to collect information in order to identify the effects of initial tissue properties on mass transport phenomena in general, and osmotic processing responses in particular. The texture profile analysis revealed cortex anisotropy of the th

Hyperresponsiveness and inflammation are major pathophysiological features of both allergic rhinitis and asthma. The mechanisms behind these are not fully understood. The aims of this thesis were to investigate if cytokines involved in the allergic response can induce airway hyperreactivity by affecting the airway smooth muscle directly and to identify novel mediators involved in allergic airway i

Multifunctional buildings have become more common in the last years. At the same time the threat from antagonistic attacks has increased. This presents challenges for the fire safety systems in multifunctional buildings since continuity of functions, especially those considered to be of societal importance, need to be operational and at the same time antagonistic exposures may present more challen

Popular Abstract in Swedish Omkring 16% av alla cancerfall i världen beräknas vara orsakade av infektioner och omkring 5% av dessa orsakas av humant papillomvirus (HPV). HPV har etablerats som orsak till livmoderhalscancer och kondylom (könsvårtor). HPV-typer som förekommer på hud har förknippats med icke-melanom hudcancer såsom skivepitelcancer (SCC) men också ofarliga hudhudförändringar som aktiAround 5% of all cancer cases worldwide are caused by human papillomavirus (HPV) which has been established as the cause of cervical cancer and genital warts (condylomas). Cutaneous HPV types have been weakly associated with non-melanoma skin lesions such as squamous cell carcinoma (SCC) and actinic keratosis (AK). We have analyzed skin and genital lesions for presence of HPV-DNA in order to searc

We present an investigation of the magnetic behavior of epitaxial MnAs films grown on GaAs(100). We address the dependence of the magnetic moment, ferromagnetic transition temperature (T-c), and magnetocrystalline anisotropy constants on epitaxial conditions. From thorough structural and magnetic investigations, our findings indicate a more complex relationship between strain and magnetic properti

We study the dynamic admission control for a finite shared buffer with support of multiclass traffic under Markovian assumptions. The problem is often referred to as buffer sharing in the literature. From the linear programming (LP) formulation of the continuous-time Markov decision process (MDP), we construct a hierarchy of increasingly stronger LP relaxations where the hierarchy levels equal the

Blanket bog is a highly distinctive biome restricted to disjunct hyperoceanic regions. It is characterized by a landscape covering of peat broken only by the steepest slopes(1). Plant and microbial life are adapted to anoxia, low pH and low nutrient availability. Plant productivity exceeds soil organic matter decomposition, so carbon is sequestered over time. Unique climatic requirements, includin

Popular Abstract in Swedish Avhandlingen handlar om tes av periodicitet och trend inom långminne-processer. Med hjälp av diskret wavelet transform och periodogram presenteras vi två test för periodicitet och tre test för trend. Vi utvärderar vår test samt studerar deras egenskaper delvis genom att använda oss av datorintensiva metoder såsom Monte Carlo och delvis genom att jämföra dem med andra liThis thesis presents methods of testing the periodicity and trend for the time series, which exhibit dependence over long periods of time. Many such processes can be modeled by a class of models called fractionally differenced processes. The first approach we consider to analyse such processes is by using the band periodogram, which divides the periodogram into different intervals or bands, matchi

In companies that constantly develop new software releases for large markets, there continually arrive new requirements, written in natural language that may affect the development work. Before any decision is made about the requirements, these must be analysed and understood, and related to the current set of implemented and queued requirements. This task is time-consuming owing to the high inflo
