Off-axis multilayer zone plate with 16 nm × 28 nm focus for high-resolution X-ray beam induced current imaging

Using multilayer zone plates (MZPs) as two-dimensional optics, focal spot sizes of less than 10 nm can be achieved, as we show here with a focus of 8.4 nm × 9.6 nm, but the need for order-sorting apertures prohibits practical working distances. To overcome this issue, here an off-axis illumination of a circular MZP is introduced to trade off between working distance and focal spot size. By this, t

Streaming instability of multiple particle species : II. Numerical convergence with increasing particle number

The streaming instability provides an efficient way of overcoming the growth barriers in the initial stages of the planet formation process. Considering the realistic case of a particle size distribution, the dynamics of the system is altered compared to the outcome of single size models. In order to understand the outcome of the multispecies streaming instability in detail, we perform a large par

Formation of planetary systems by pebble accretion and migration : Hot super-Earth systems from breaking compact resonant chains

At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii and orbital periods of less than 100 days.We use N-body simulations including a model for gas-assisted pebble accretion and disk–planet tidal interaction to study the formation of super-Earth systems.We show that the integrated pebble mass reservoir creates a bifurcation between hot super-Earths or hot-Neptu

Formation of Venus, Earth and Mars : Constrained by Isotopes

Here we discuss the current state of knowledge of terrestrial planet formation from the aspects of different planet formation models and isotopic data from 182Hf-182W, U-Pb, lithophile-siderophile elements, 48Ca/44Ca isotope samples from planetary building blocks, recent reproduction attempts from 36Ar/38Ar, 20Ne/22Ne, 36Ar/22Ne isotope ratios in Venus’ and Earth’s atmospheres, the expected solar

Effect of nucleation on icy pebble growth in protoplanetary discs

Solid particles in protoplanetary discs can grow by direct vapour deposition outside of ice lines. The presence of microscopic silicate particles may nevertheless hinder growth into large pebbles, since the available vapour is deposited predominantly on the small grains that dominate the total surface area. Experiments on heterogeneous ice nucleation, performed to understand ice clouds in the Mart

Capsule Independent Antimicrobial Activity Induced by Nanochitosan against Streptococcus pneumoniae

BACKGROUND: Streptococcus pneumoniae remains a major cause of community-acquired pneumonia, meningitis, and other diseases, contributing significantly to high morbidity and mortality worldwide. Although it responds to antibiotics, their use is becoming limited due to the rise in antibiotic resistance, which necessitates the development of new therapeutics. Nanotechnology is used to counteract anti

Recent Patent based perspective on diagnostic and therapeutic interventions in Malignant Mesothelioma: Is Drug Repositioning knocking the door?

Background: Malignant Mesothelioma (MM), an orphan but aggressive malignancy of the mesothelial membrane, is a fatal tumor. Global epidemic related to malignant pleural mesothelioma is on the rise, so there is a need to explore novel biomarkers and ingenious therapeutic approaches to stalk this silent killer.Objective: The main aim of the present review is to provide a consolidated overview of the

Transforming trash to treasure Cultural ambiguity in foetal cell research

Background: Rich in different kind of potent cells, embryos are used in modern regenerative medicine and research. Neurobiologists today are pushing the boundaries for what can be done with embryos existing in the transitory margins of medicine. Therefore, there is a growing need to develop conceptual frameworks for interpreting the trans‐ formative cultural, biological and technical processes inv

Glimmingehus : A Building-Archaeological Investigation of the Interior

An interior building-archaeological investigation of parts of Glimmingehus castle has been conducted. One of the aims was to document the two large rooms, today called “the Banqueting Hall” and “the Archers’ Loft”. Another was to answer some questions about the original functions of the rooms. The two rooms are connected by a simple wooden staircase. One of the questions concerned the original loo

Status, pride, and educational motivation : Understanding differences in attitudes to education from the perspective of evolutionary emotion theory

The present study suggests that the theoretical framework of evolutionary psychology, in particular theories and models relating to social status and pride, can be used to further our understanding of educational motivation. Our assumption was that the desire for social recognition and high status is a universal human phenomenon. Based on this, we suggested that differences in educational motivati

PFAS in the water supply: source water contamination

Water contamination with per- and polyfluoroalkyl substances (PFAS) is a serious problem for water suppliers in many regions. Due to persistence of the substances and a complex distribution mechanism, PFAS can have an adverse impact on water quality. Reported toxicological and health effects, make it very important to minimise the of wildlife and human exposure to PFAS. The exposure path is, howev

Fostering Knowledge uptake in Emerging Innovation Systems : Enhancing Conditions for Innovation in Rwanda

Knowledge, when used effectively, is a major input for development. However, the processes associated with knowledge production, knowledge transfer, and knowledge use are complex and not easy to facilitate in certain parts of the world. This is mainly due to a lack of or limited interactions between knowledge producers and knowledge users. This thesis aims to explore how efforts to foster knowledg

Genomic editing of metformin efficacy-associated genetic variants in SLC47A1 does not alter SLC47A1 expression

Several pharmacogenetics studies have identified an association between a greater metformin-dependent reduction in HbA1c levels and the minor A allele at rs2289669 in intron 10 of SLC47A1, encoding multidrug and toxin extrusion 1 (MATE1), a presumed metformin transporter. It is currently unknown if the rs2289669 locus is a cis-eQTL, which would validate its role as predictor of metformin efficacy.

Critical factors for the realization of sustainable supply chain innovations : model development based on a systematic literature review

The challenges of sustainable development require whole supply chains and networks to drive change and innovation. However, most existing research on sustainable innovations is on a company level and the dominating company focus in practice drives “silo” approaches, short-term thinking, and profit maximization. Consequently, there is a need for research and new models that facilitate sustainable sThe challenges of sustainable development require whole supply chains and networks to drive change and innovation.
