Microgels are interesting as potential delivery systems for antimicrobial peptides. In order to elucidate membrane interactions of such systems, we here investigate effects of microgel charge density on antimicrobial peptide loading and release, as well as consequences of this for membrane interactions and antimicrobial effects, using ellipsometry, circular dichroism spectroscopy, nanoparticle tra
Hypothesis The rheological control of suspensions is of key interest in the formulation design. A chemically cross-linked hydrophobically modified poly(acrylic acid) (HMCL-PAA), used as rheology modifier, is pH sensitive and shows swelling behavior above a critical pH due to the ionization of the acrylic acid groups. At low pH, HMCL-PAA suspensions are liquid and turbid. The binding of surfactants
Lignocellulosic biomass is a promising alternative fuel source which can promote energy security, reduce greenhouse gas emissions, and minimize fuel consumption when paired with advanced combustion strategies. Pyrolysis is used to convert lignocellulosic biomass into a complex mixture of phenolic-rich species that can be used in a transportation fuel. Anisole (or methoxybenzene) can be used as a s
In order to improve the selectivity in photocatalytic process, molecularly imprinted photocatalysts containing a low loading of TiO2 (from 6.6 to 16.6% of total mass) were prepared for photocatalytic degradation of an organic pollutant, diclofenac (DIC). The photocatalytic component TiO2 (P25), with and without being doped with Cu2O, was embedded in diclofenac-imprinted polymers. The molecularly i
Ethnographic (and other) studies on teachers often rely on two kinds of material: observations of teaching practices in the classroom; and statements about teaching practices, extracted both from involved actors (e.g. teacher interviews) and from documents (e.g. educational policy documents or teaching manuals). Many scholars agree that there is a discrepancy between what is stated, or desired, pr
The contribution of forest harvesting to base cation losses and soil acidification has increased in recent years in Sweden, as the demand for bioenergy has increased and the sulphur deposition has decreased. Thus, new policy tools are required to evaluate the progress of the recovery from acidification, and as a basis for forest management recommendations. In this study we introduce and test a con
In the Western hemisphere, the opposition of surveillance versus privacy appears to be common sense: any technology use with the potential risk of infringing upon personal integrity and privacy is in return expected to lead to substantial improvements in security in order to constitute a legitimate course of action. In China, the main problem of inhibiting the free flow of information is rarely se
Industrialized building companies apply various product predefinition strategies, derived from market- or resource-based strategic perspectives. This strongly affects the buildup of such companies' business models and their operational structure. Ten companies were included in a case study, presenting strategic orientations and business models. The aim of this study was to analyze the primary char
This study uses three-dimensional (3D) printing technology as a tool for designing carriers for immobilization of microbial cells for bioprocesses. Production of propionic acid from glucose by immobilized Propionibacterium sp. cells was studied as a model system. For cell adsorption, the 3D-printed nylon beads were added to the culture medium during 3 rounds of cell cultivation. Cell adsorption an
The paper addresses the theoretical concept and methodological usefulness of 'lay theories' for conducting comparative research. 'Lay knowledge' is a well-researched concept particularly in medicine and health (e.g. Williams & Popay 2006), even if often regarded as an 'obstacle' that needs to be overcome in order to spread 'proper' scientific, medical knowledge. Critical studies within medicin
Indoor air pollution has caused increasing concern in recent years. As we spend most of our lives indoors, it is crucial to understand the health effects caused by indoor air pollution. Household dust serve as good proxy for accessing indoor air pollution, especially smaller dust particles that can pass into the lungs are of interest. In this study we present an efficient method for the isolation
Hydrolysis of arabinoxylan (AX) by glycoside hydrolase family 10 (GH10) xylanases produces xylo- and arabinoxylo-oligosaccharides ((A)XOS) which have shown prebiotic effects. The thermostable GH10 xylanase RmXyn10A has shown great potential to produce (A)XOS. In this study, the structure of RmXyn10A was investigated, the catalytic module by homology modelling and site-directed mutagenesis and the
Denna avhandling behandlar en mängd mikrostrukturella och molekylära lämningar som påträffats i ett antal fossil. Resultaten presenteras i sex vetenskapliga artiklar med det gemensamma syftet att grundligt studera dessa lämningar med hjälp av såväl nya som vedertagna analysmetoder. Avhandlingens huvudsakliga frågeställningar är dels vad denna typ av fossila spår kan säga om de studerade djurens biThis thesis comprises investigations of microstructures and molecular remains, preserved in a variety of fossil specimens. The results are presented in six papers, collectively aiming to thoroughly examine fossil traces of such remains by employing a combination of both established and relatively new analytical methods. The main questions asked are: What can we learn about the biology, ecology and
The aim of this work is to characterize the precipitation kinetics in Haynes® 282® superalloys using in-situ high-energy Small Angle X-ray Scattering (SAXS) together with Wide Angle X-ray Scattering (WAXS). The phases identified by WAXS include γ (matrix), γ′ (hardening precipitates), MC (metallic carbides), and M23C6/M6C (secondary metallic carbides). The γ’-precipitates are spheroids with a diam
The circular economy (CE) can be a driver for sustainability and CE can be promoted and supported by the creation of new and innovative business models, which embed CE principles into their value propositions throughout the value chains. This study focuses on the environmental value propositions of the CE business models. The term environmental value proposition refers here to an absolute value be
We report measurements of the inclusive J/ψ yield and average transverse momentum as a function of charged-particle pseudorapidity density dNch/dη in p–Pb collisions at sNN=5.02TeV with ALICE at the LHC. The observables are normalised to their corresponding averages in non-single diffractive events. An increase of the normalised J/ψ yield with normalised dNch/dη, measured at mid-rapidity, is obser
Latin America is the most unequal region in the world. The current sustainable development agenda increased attention to health inequity and its determinants in the region. Our aim is to investigate the social gradient in health in Latin America and assess the effects of social capital and income inequality on it. We used cross-sectional data from the World Values Survey and the World Bank. Our sa
This paper experimentally studies unilateral communication of intentions in eight different two-player one-shot normal form games with complete information. We find that communication is used both to coordinate and to deceive, and that messages have a significant impact on beliefs and behavior even in dominance solvable games. Nash equilibrium and cognitive hierarchy jointly account for many regul
The Paleo- and Mesoproterozoic fossil record of multicellular eukaryotes is scarce but extremely important in studying the evolution of life in the Precambrian Era. Typically, fossils heralded as ‘multicellular eukaryotes’ that are older than the Ediacaran are met with controversy. To confront such debates, we investigate the chemical, isotopic, and molecular structural characteristics of organic
