Recommendations for implementation of clamping strength in SteenToets: Kennisontwikkeling t.b.v. SteenToets 2006 Onderdeel 1 Normaalkracht

This report belongs to the research programme on unknown aspects of Block Revetment systems. The stability of block revetments under wave loading is presumed to benefit from clamping forces. In previous studies a physical model for clamping forces was developed and verified. The existing design and design checking software code SteenToets...

A plea for putting the issue of Urbanizing Deltas on the New Urban Agenda, UN Habitat III

Urbanizing deltas belong to the most promising regions of the world, considering their large concentrations of population, their role in the world’s ecosystems and their significance to the world’s economy. At the same time, these regions are dealing with extreme vulnerability and face multiple threats. The combination of intensification of...

Demystifying the unseen helmsman: Towards a competency model for game facilitators

The facilitation of game sessions is an endeavor that requires specific competencies. A game facilitator needs to be an ‘unseen helmsman’ steering his/her ship of game players clear from rocks and storms without the players realizing. However, the competencies required for game facilitation are somewhat shrouded in mystery. In the past, several...

Computing volumes and surface areas including party walls for the 3DBAG data set

This document provides a description of the project “Computing volumes and surface areas including party walls for the 3DBAG dataset” which has been carried out between the 3D Geoinformation group at TU Del6, 3DGI, and RVO in the timeframe between November 2022 and October 2023.<br/><br/>The goal of this project is to derive parameters from the...

MRI Contrast Agents in Glycobiology

Molecular recognition involving glycoprotein-mediated interactions is ubiquitous in both normal and pathological natural processes. Therefore, visualization of these interactions and the extent of expression of the sugars is a challenge in medical diagnosis, monitoring of therapy, and drug design. Here, we review the literature on the...

Mn(III) porphyrins as potential MRI contrast agents for diagnosis and MRI-guided therapy

Mn(III) porphyrins have great potential as Gd-free MRI contrast agents because both the cation and the ligand have interesting properties. The redox properties of the Mn(III)-ion can be exploited for the preparation of reactive oxygen species for therapy. Moreover, the porphyrin ligand allows these complexes to have a high affinity for tumor...

Metal- and covalent-organic framework mixed matrix membranes for CO₂ separation: a perspective on stability and scalability

Membrane technology has attracted great industrial interest in carbon capture and separation owing to the merits of energy-efficiency, environmental friendliness and low capital investment. Conventional polymeric membranes for CO₂ separation suffer from the trade-off between permeability and selectivity. Introducing porous fillers...

Engagement in Human-Agent Interaction: An Overview

Engagement is a concept of the utmost importance in human-computer interaction, not only for informing the design and implementation of interfaces, but also for enabling more sophisticated interfaces capable of adapting to users. While the notion of engagement is actively being studied in a diverse set of domains, the term has been used to...

Exploration and exploitation of the uncommon pH profile of the dynamic covalent interactions between boronic acids and N-acetylneuraminic acids

In this review, the chemical mechanisms behind the interactions between boronic acids and N-acetylneuraminic acids, which have been widely utilized in biomedicine in recent decades, will be examined. It will also be highlighted that the affinity of boronic acids for N-acetylneuraminic acids is dependent on pH and is complementary to their...

The future of cardiovascular magnetic resonance: All-in-one vs. real-time (Part 1)

Cardiovascular magnetic resonance (CMR) protocols can be lengthy and complex, which has driven the research community to develop new technologies to make these protocols more efficient and patient-friendly. Two different approaches to improving CMR have been proposed, specifically “all-in-one” CMR, where several contrasts and/or motion states...

Relaxivity of manganese ferrite nanoparticles

Manganese ferrite nanoparticles are superparamagnetic and have very high saturation magnetization, which makes them candidates for application as MRI contrast agents. Because these nanoparticles are very effective enhancers of transverse relaxation, they are particularly suitable as negative (T₂-weighted) contrast agents. The...

The chemical consequences of the gradual decrease of the ionic radius along the Ln-series

In the periodical system, the lanthanides (the 15 elements in the periodic table between barium and hafnium) are unique in the sense that their trivalent cations have their valence electrons hidden behind the 5s and 5p electrons. They show a gradual decrease in ionic radius with increasing atomic number (also known as the lanthanide...

A systematic review and meta-analysis of thermal coagulation compared with cryotherapy to treat precancerous cervical lesions in low- and middle-income countries

Background: Thermal coagulation is gaining popularity for treating cervical intraepithelial neoplasia (CIN) in screening programs in low- and middle-income countries (LMICs) due to unavailability of cryotherapy. Objectives: Assess the effectiveness of thermal coagulation for treatment of CIN lesions compared with cryotherapy, with a focus on...
