Hypothesis: The stability of colloidal dispersions in the presence of multivalent ions depends strongly on the electrostatic interactions between the suspended particles. Of particular interest are colloidal particles having dimensions in the nanometric range and with an anisotropic shape due to its high surface area per unit mass, for example clay, which has the key characteristic of a negatively
Experimental and numerical studies were performed to understand the stabilization of lean premixed natural gas/air flames in a gas turbine model combustor which was equipped with a swirl burner, known as the CECOST burner, designed to replicate the flow and flame structures in an industrial gas turbine engine. The operability range, flame stabilization, and flashback were investigated employing si
We present a program to compute polarizabilities of nominal one-electron systems using the Lagrange-mesh method (LMM) (Baye, 2015), that was used by Filippin et al., (2018). A semiempirical-core-potential approach is implemented, ultimately solving a Dirac-like equation by diagonalizing the corresponding Hamiltonian matrix. In order to build the core potential, the core orbitals are obtained from
Hypothesis: Doxorubicin hydrochloride (DX) is widely used as a chemotherapeutic agent, though its severe side-effects limit its clinical use. A way to overcome these limitations is to increase DX latency through encapsulation in suitable carriers. However, DX has a high solubility in water, hindering encapsulation. The formulation of DX with sodium cholate (NaC) will reduce aqueous solubility thro
Low-dimensionality materials are highly susceptible to interfaces. Indeed, intercalation of different chemical species in between epitaxial graphene and silicon carbide (SiC), for instance, may decouple the graphene with respect to the substrate due to the conversion of the buffer layer into a graphene layer. O-intercalation is known to release the strain of such 2D material and to lead to the for
Heterogeneity in episodic memory functioning in aging was assessed with a pattern-completion functional magnetic resonance imaging task that required reactivation of well-consolidated face-name memory traces from fragmented (partial) or morphed (noisy) face cues. About half of the examined individuals (N = 101) showed impaired (chance) performance on fragmented faces despite intact performance on
Background: Reduction of insertion injury is likely important to approach physiological conditions in the vicinity of implanted devices intended to interface with the surrounding brain. New methods: We have developed a novel, low-friction coating around frozen, gelatin embedded needles. By introducing a layer of thawing ice onto the gelatin, decreasing surface friction, we mitigate damage caused b
Wheat bran arabinoxylan can be converted by enzymatic hydrolysis into short arabinoxylo-oligosaccharides (AXOS) with prebiotic potential. Alkali extraction of arabinoxylan from wheat-bran offers advantages in terms of yield and results in arabinoxylan with highly-substituted regions which has been a challenge to hydrolyse using endoxylanases. We show that this hurdle can be overcome by selecting a
We determine a counterexample to strong diamagnetism for the Laplace operator in the unit disc with a uniform magnetic field and Robin boundary condition. The example follows from the accurate asymptotics of the lowest eigenvalue when the Robin parameter tends to − ∞.
Objective: The aim was to analyse risk of forearm fractures in first- and second-generation immigrants to Sweden. Methods: A nationwide study of individuals 20 years of age and older was conducted. Forearm fractures were defined as at least one registered diagnosis in the National Patient Register between January 1, 1998 and December 31, 2012. Cox regression analysis was used to estimate the relat
Instead of featuring a long-awaited convergence process, the second half of the twentieth century witnessed a dramatic income divergence across countries. We propose cultural distance between countries as a determinant of this economic divergence. Cultural similarity makes it easier for societies to interact, learn and adopt from one another. Consequently, cultural differences may lead to economic
This brief note, on the Bundesverfassungsgericht’s Weiss judgment of 5th May 2020, highlights three implications of the German Federal Constitutional Court’s landmark ruling and its constitutional significance with implications for the wider context of Member States’ cooperation in the EU and European integration as a whole. We explain the relevant background of the judgment and argue that the spe
1. Dementia is a clinical syndrome with several causes whichcreates impairments in mental ability, personality, affect andsocialisation.2. Information from family members can be very useful in theearly identification of cognitive impairment.3. Patients presenting with cognitive impairment should be evaluatedfor potentially reversible causes, with a range of laboratorytests and investigations.4. Sh
Apart from microhardness and elastic modulus, the stress-strain relation is another important characteristic that more and more scholars have been trying to extract from nanoindentation. With the development of artificial intelligence and computer technology, a machine learning based method is proposed in this paper to extract stress-strain curve of grey cast iron using sharp nanoindentation. Firs
Building extraction has attracted considerable attention in the field of remote sensing image analysis. Fully convolutional network modelling is a recently developed technique that is capable of significantly enhancing building extraction accuracy. It is a prominent branch of deep learning and uses advanced state-of-the-art techniques, especially with regard to building segmentation. In this paper
Abstrakt. Gradientval av överföringar gör det möjligt att förenkla polarisationsöverföringssekvenser genom att utelämna kemiska skift-återfokuseringspulser. Funktionerna hos en förenklad STEM-sekvens med tre pulser för {1H-13C} polarisationsöverföring har studerats vid 2 Tesla på ett helkropps MR-system med avseende på användning av MR-spektroskopi in vivo. Den observerade signalen ökas genom ne
Mechanisms of motor deficits (e.g. hemiparesis and hemiplegia) secondary to stroke and traumatic brain injury remain poorly understood. In early animal studies, a unilateral lesion to the cerebellum produced postural asymmetry with ipsilateral hindlimb flexion that was retained after complete spinal cord transection. Here we demonstrate that hindlimb postural asymmetry in rats is induced by a unil
A native passive film on 25Cr-7Ni super duplex stainless steel was analyzed using synchrotron hard X-ray photoemission electron microscopy, focusing on variations between individual grains of ferrite and austenite phases. The film consists of an oxide inner layer and an oxyhydroxide outer layer, in total 2.3 nm thick. The Cr content is higher in the outer than the inner layer, ca. 80 % on average.
This study examines how Islamic beliefs affect host-guest interactions from the perspectives of local people in two Islamic heritage villages in Iran. Face-to-face interviews with 51 people across the two settings highlight the significant influence of Islamic beliefs on host-guest interactions and indicate that these beliefs can be supportive of tourism. However, religiosity also significantly in
