“Barbarous Custom of Dueling”: Death and Honor on St. Louis’ Bloody Island
No full textNeels argues that the Army Corps of Engineers inadvertently dealt the final death blow to dueling in the region when it eliminated “Bloody Island,” a sandbar in the Mississippi River which became a favorite venue for duels

Local childcare availability and dual earner fertility in Belgium
No full textAbstract: In the context of population ageing, work-family reconciliation policies potentially play an important role in supporting both fertility and parental employment. However, the evaluation of such policies remains a challenge. Using population data for Belgium, Jonas Wood and Karel Neels find that the local availability of formal childcare positively affects fertility among dual earner couples
Di-mu-acetato-mu-aqua-bis[acetatobis(1H-benzimidazole)cobalt(II)]
No full textIn the title compound, [Co2(C2H3O2)4(C7H6N2)4(H2O)], the half-molecule in the asymmetric unit is completed by a crystallographic twofold rotation axis to give the full molecule. The CoII ions are approximately octahedrally coordinated with a cis-N2O4 coordination sphere. The compound features intramolecular O-HO hydrogen bonds between the non-bridging acetate groups and the bridging water molecule, and intermolecular N-HO hydrogen bonds between the acetates and amine H atoms of the benzimidazoles which determine the molecular packing in the crystal structure
Crystal engineering of a series of arylammonium copper(II) malonates
No full textWe present a series of eight layered copper(II) malonates, each with a {[HA](2)[Cu(II)(mal)(2)(H(2)O)]}(n) A-B-A layer structure, where A is an ammonium cation and 13 is an anionic copper malonate layer (x = 1 or 2; A = benzylamine, 1; S-(alpha)-methylbenzylamine, 2; 4-methylbenzylamine, 3; 4-carboxybenzylamine, 4; 4-trifluoromethylbenzylamine, 5; 4-trifluoromethoxybenzylamine, 6; phenylethylamine, 7; and 4-fluorophenylethylamine, 8). The ammonium cations used are primary amines based around benzylamine and phenylethylamine and include several different functional groups. The different amines give a large array of interlayer interactions, including van der Wail Is packing, hydrogen bonding, C-H center dot center dot center dot pi, pi-center dot center dot center dot pi, H center dot center dot center dot F, and F center dot center dot center dot F. interactions. [Despite the various functionalities on the arylammonium groups, the different interlayer packing interactions, and the differing degrees of hydration in the [Cu(II)(mal)(2)(H(2)O)(x)](2-) group, the anionic layer structure remains the same, indicating a high stability of this layer and its potential for further engineering of the organic layer components
African Principles on the Law Applicable to International Commercial Contracts
No full textThis booklet contains the first draft of the envisaged African Principles on the Law Applicable to International Commercial Contracts. The proposal could be used by national legislators on the continent and African economic integration organisations, particularly the African Union, in, respectively, domestic legislation and regional or supranational laws of a soft or binding nature. The existence of a reliable transnational legal infrastructure in respect of international commercial law, including commercial private international law, is a prerequisite for investor confidence, inclusive economic growth, sustainable development, and the ultimate alleviation of poverty on the African continent. The instrument may contribute to sustainable growth on a long-term basis. The regulation of private international law of contract is essential to the further development of the African Continental Free Trade Area.
Jan L Neels is professor of private international law and director of the Research Centre for Private International Law in Emerging Countries at the University of Johannesburg

Spatial and temporal evaluation of iodine uptake and radiodensity in meniscus tissue using contrast-enhanced micro-CT
No full textRationale and objective: The visualization of soft tissues, like the meniscus, through X-ray micro-computed tomography (micro-CT), requires the use of contrast agents (CAs). While other studies have investigated CA diffusion in fibrocartilagineous tissues, this work aimed to optimize iodine staining protocols for meniscal tissue that improve their visualization by micro-CT. Specific objectives included evaluating the diffusion of CAs within meniscal samples over time, assessing volume changes due to staining, and identifying the iodine ions absorbed by the tissue. Materials and methods: Water-based and PBS-based Lugol solutions (KI3) were used to stain sheep and pig menisci for 24 days. Samples were scanned using micro-CT at different time points (0, 1, 4, 8, 12, 16, 20, and 24 days) to monitor CA diffusion and volume changes. Micro-CT provided three-dimensional (3D) visualization of iodine distribution and quantification of volume changes and radiodensity in the menisci. Additionally, UV–visible spectroscopy (UV–vis) analyses were performed to determine the uptake of iodine ions by the meniscus. Results: Results indicated volumetric shrinkage and increased radiodensity within the first days of staining, with diffusion primarily occurring from the periphery of the meniscus. UV–visible spectroscopy identified two iodide ions in the CA solution (I− and I3−) and revealed a preferential absorption of the triiodide ion (I3−). Conclusion: This study demonstrated the utility of iodine-based CAs and micro-CT technique for visualizing and investigating the spatial and temporal iodine diffusion within the meniscal tissue of sheep and pigs. The findings of this study have important implications for using iodine-based CAs in imaging analyses of the meniscus and offer potentially valuable insights into the diffusion patterns of iodine in fibrocartilagineous tissues
Coordination chemistry of a pi-extended, rigid and redox-active tetrathiafulvalene-fused Schiff-base ligand
No full textA ?-extended, redox-active tetradentate tetrathiafulvalene-fused salphen [salphen = N,N?-phenylenebis(salicylideneimine)] compound (L) was prepared via a direct Schiff-base condensation of the corresponding diamine-tetrathiafulvalene (TTF) precursor with salicylaldehyde. Its chelating coordination ability has been demonstrated by the formation of the corresponding transition metal complexes in the presence of M(OAc)2·nH2O (M = Co(II), Ni(II), Cu(II)) and FeCl3·6H2O. Three complexes have been characterized by single-crystal X-ray diffraction analysis showing that the TTF-salphen ligand coordinates to the metal ions in a planar mode through the nitrogen and oxygen atoms in a N2O2 cis-configuration. In the case of Fe(III), a dinuclear oxo-bridged Fe(III) complex is formed. These paramagnetic complexes are promising building blocks for the construction of dual functional materials due to their unique structural features (planarity and rigidity) as well as their inherent redox properties
