Gel formation by surfactant molecules is generally controlled by thermodynamics rather than kinetics. Mixtures of long-chain alcohols and surfactants are widely used in various cosmetic and pharmaceutical products. The cooling rate used to produce the products is known to be a key parameter to control the rheological properties and the final texture. However, the physical-chemistry links between t
We present the macroscale three-dimensional numerical solution of anisotropic Biot's poroelasticity, with coefficients derived from a micromechanical analysis as prescribed by the asymptotic homogenisation technique. The system of partial differential equations (PDEs) is discretised by finite elements, exploiting a formal analogy with the fully coupled thermal displacement systems of PDEs implemen
The suspended solids (SS) concentrations in effluent from moving bed biofilm reactors (MBBRs) used for secondary biological treatment can be up to 500 mg/L. Microscreens (Drumfilters or Discfilters) can be used as alternatives to traditional clarification or dissolved air flotation to remove SS and total phosphorus (TP). This study shows how a small-scale municipal WWTP for 5,700 population equiva
A systematic study of the photophysical and electrochemical properties of triscyclometalated homoleptic iridium(III) complexes based on 2-(1-naphthyl)pyridine (npy) ligands is presented. A systematic investigation of ligand substitution patterns showed an influence on the lifetime of the excited state, with slight changes in the absorption
In this retrospective study, 92 patients (83% attendance rate) were examined 6 years after open carpal tunnel release. A questionnaire was answered by the patient and a physical examination was made by an independent observer. Five complications were found, of which 4 were early postoperative problems and one was a major complication with long-term disability. In one third of the patients numerous
The R&D project GMES4Mining aims to support particular tasks within the different phases of a mining life cycle. Within this project one task concentrates on vegetation monitoring in order to detect damages caused by mining. In Germany several mining districts have been exploited for a long time. Mining areas are associated with certain environmental hazards, such as surface subsidence and flo
Background: Alzheimer’s disease (AD) is an insidiously progressive neurodegenerative disorder that is characterized by multiple cognitive impairments and gradual loss of independence in carrying out activities of daily living (ADL). Currently, the predominant therapy for mild-to-moderate AD is cholinesterase inhibitors (ChEIs), which have been shown to have positive effects on symptoms compared wi
Deep sea mining (DSM) is by its proponents heralded as a sustainable way to supply the renewable energy transition with the massive amount of minerals and metals it requires, while its critics fear it will be the final drop making the oceanic cup flow over into ecological disaster. While commercial DSM remains unprecedented and its consequences largely unknown, private companies are using its “gre
I ljuset av den forskning som har konstaterat att människor som har genomgått viktoperation mår betydligt fysiskt och psykiskt bättre efter viktoperation, saknas nyansering av hur de olika personerna har upplevt sina kroppar och sig själva lång tid efter viktoperationen. Denna kvalitativa studie syftade att undersöka viktopererades kroppsuppfattning och självkänsla mer än tio år efter viktoperatio
Abstract in UndeterminedThere has been much interest in group judgment and the so-called 'wisdom of crowds'. In many real world contexts, members of groups not only share a dependence on external sources of information, but they also communicate with one another, thus introducing correlations among their responses that can diminish collective accuracy. This has long been known, but it has-to date-
Child abuse, including physical, sexual, or emotional violence or neglect, is a global problem with serious and long-term consequences for children. Even though child abuse is prohibited in Denmark, the estimated number of physically and sexually abused children is relatively high, whereas the annual number of forensically examined children is low. We present the Danish practice and legal foundati
This research investigates the behavior of intrinsically disordered proteins (IDPs) in solution, especially the self-associating saliva protein Statherin, by a combined computational and experimental approach. For the computational part, a bead necklace model previously parameterised for Histatin 5 was used. This model was shown to be applicable to a range of monomeric intrinsically disordered pro
One of the hallmark findings from behavioral economics is that choices are sensitive to the context they are presented in. However, the strength of such 'framing effects' varies between studies, and some studies fail to find any effect at all. A long line of research has argued that the presence and size of framing effects depend to a large extent on whether people use higher or lower-level mental
The rate of water exchange across cell membranes is a parameter of biological interest and can be measured by diffusion magnetic resonance imaging (dMRI). In this work, we investigate a stochastic model for the diffusion-and-exchange of water molecules. This model provides a general solution for the temporal evolution of dMRI signal using any type of gradient waveform, thereby generalizing the sig
This dissertation deals with memory, recognition and solidarity in the Nowa Huta district of Kraków, Poland. Nowa Huta was founded as an independent, socialist model town in 1949, together with the large Lenin Steel Plant, and was incorporated into Kraków in 1951. In the 1980s the steel plant and district became one of the main centers of the oppositional Solidarity movement in Poland. Situated be
BACKGROUND: Hyperthyroidism is associated with alterations in metabolism that are currently only partially understood. The objective of the study was to investigate changes in metabolism associated with reinstatement of euthyroidism in Swedish patients.METHODS: Eighty metabolites in plasma were profiled from 10 subjects with Graves' disease (GD) at baseline and after 9 and 15 months of treatment t
The Sahara Desert is one of the largest land-based barriers on the Earth, crossed twice each year by billions of birds on migration. Here we investigate how common swifts migrating between breeding sites in Sweden and wintering areas in sub-Saharan Africa perform the desert crossing with respect to route choice, winds, timing and speed of migration by analysing 72 geolocator tracks recording migra
The poor survival of embryonic dopaminergic (DA) neurons transplanted into patients with Parkinson's disease (PD) has encouraged researchers to search for new methods to affect the short- as well as long-term survival of these neurons after transplantation. In several previous rodent studies Sertoli cells increased survival of islet cells and chromaffin cells when cotransplanted in vivo. The aims
In this paper, the performance of a binary phase shift keyed random time-hopping impulse radio system with pulse-based polarity randomization is analyzed. The effects of interframe interference and multiple-access interference on the performance of a generic Rake receiver are investigated for asynchronous systems in frequency-selective environments. A key step is to model the asynchronous system a
We devise a stochastic and spatially explicit model for the dynamics of the initials cells in a stratified shoot apical meristem (SAM). The meristem is composed of three layers with seven initials per layer. We investigate the probability and number of divisions for a mutant lineage to either reach fixation or becoming purged through selection or drift. In contrast to previous studies our results
