Authors: Akagbue Vivian Ndidi , Nonye-Enyidah Esther I. , Aderibigbe Gbenga Jacob 
Published: November 2022

Background: Hysterosalpingography (HSG) is one of the imaging modality used in evaluating females presenting with complaints of infertility. Infertility is not just the issue of the couples alone both the extended family is involved in the typical African environment, therefore it is essential to identify possible causes and proffer solutions where possible.
Aim: This study is aimed at documenting the indications and findings among women presenting for hysterosalpingographic studies in the Radiology Department of Rivers State University teaching Hospital (RSUTH).
Setting and Design: A retrospective study, was conducted at the Radiology and the Obstetrics and Gynaecology Departments of a tertiary hospital.
Materials and Methods: Assessment of patients who had Hysterosalpingography (HSG) done from 1st January, 2020 to 31st May, 2022 in the Radiology Department of RSUTH. Biodata and indications for the study were obtained from the request forms and the HSG findings were also obtained from results pool.
Statistical Analysis: Data were analyzed using SPSS 21.0 version. The level of statistical significance was set at p<0.05.
Results: A total of 305 women data were analyzed. The age of the study group was between 21 to 48years with a mean age of 35.21±5.48years. Majority of the age group was 31-35years (n=96, 31.5%). Secondary infertility (n=216, 70.8%) was the most common indication for HSG. Normal HSG was seen in 84(27.5%) of the patients and others had one pathology or the other. Commonest uterine pathology is uterine fibroids (n=100, 32.8%) and bilateral tubal occlusion (n=47, 20.8%) is the most frequent tubal pathology. There was a significant association between age and tubal occlusion (P=0.007).
Conclusion: HSG is still a valuable tool for investigating women in gynaecological clinics. Tubal occlusion is the prevailing pathology from this study and secondary infertility is the most common indication for HSG.

Centring Civilisation: Now and After the Apocalypse
Authors: de Salvatierra Alberto 
Published: November 2022

AbstractThe intersection of cities, bodies and politics and their material flows creates an interdisciplinary platform for new radical urbanisms. Alberto de Salvatierra, founder and director of the Center for Civilization and assistant professor of urbanism and data in architecture at the University of Calgary in Alberta, Canada, believes we are at a critical perturbation in human society, that all that has been stable for some time is now changing, more voices are being heard, and one dominant point of view is no longer predicated.

The Eruv as Legal Fiction: Changing Rules in the Public Realm
Authors: Bernbaum Piper 
Published: November 2022

AbstractAssistant Professor at the Azrieli School of Architecture and Urbanism at Carleton University in Ottawa, Piper Bernbaum finds magic in ‘legal fictions’, and especially the Jewish eruv. While many legal fictions offer privileges to individuals and create spatial systems of power, the eruv is not exclusive; it includes the existing urban fabric of the city and all its people, and on the Sabbath emancipates the orthodox community to provide an extended domain of domestic space.

Engineering Nanoclay Edges to Enhance Antimicrobial Property against Gram‐Negative Bacteria: Understanding the Membrane Destruction Mechanism by Contact‐Kill
Authors: Wang Jie , Meng Yuhang , Jiang Zhiyi , Sarwar Muhammad Tariq , Fu Liangjie , Yang Huaming 
Published: November 2022

AbstractThe overuse or abuse of antibiotics has led to serious health problems. During the recent decades, among the various methods used in antibacterial applications, some nanoclay minerals are proved antibacterial or inhibitory to the bacterial growth. However, the antibacterial mechanism of contact‐kill based on the intrinsic structure of nanoclays is still unclear. Here, the antibacterial ability of pure clay is enhanced by creating more edge surfaces on kaolinite (Kaol) and the antibacterial mechanism is clarified at the atomic level. Based on experiments and density functional theory/molecular dynamics calculations, the positively charged Al(OH) and Al(OH2) species on the edge surfaces of Kaol are confirmed to kill the Escherichia coli cells through direct contact by destroying their outer membrane (OM). The strong hydrogen bonding and van der Waals forces between OM and (110)/(10) surfaces of Kaol lead to the folding of OM. Simultaneously, the proton‐coupled electron transfer between Lipopolysaccharide (LPS) and (10) edge surface of Kaol causes the dissociation of phosphoryl groups on LPS. Considering the similarities of most nanoclayson their edge surfaces, this finding may shed some light on the development of new nanoclay‐based antibacterial materials in the future.

AbstractThe use of metal halides promotes the development of X‐ray detectors (XDs) owing to their excellent X‐ray absorbance, electrically benign defects, and large mobility−lifetime (µτ) product. Yet the severe baseline drift, size limitation, large dark current, and mediocre stability are still waiting to be solved. Herein, high density size‐scalable Cs4PbBr6 wafer‐based XD is constructed by the hot isostatic‐pressed method for the first time. Meanwhile, different Br− vacancy (VBr) concentration‐based Cs4PbBr6 is realized. The role of VBr in electrical structure and charge transport is highlighted by density functional theory and experimental measurement. Moreover, the further study points the 0D structure endows Cs4PbBr6 with high activation energy for ionic transport (1044 meV) and bandgap (3.88 eV), which finally results in an ultra‐stable baseline and thermal stability. On the basis of efficient response (7068 µC Gyair−1 cm−2), reliable current output, ultra‐low detection limit (1.75 nGyair s−1), high spatial resolution (5.2 lp mm−1 at modulation transfer function = 0.2), fast response speed and radiation stabilities (>1000 Gyair), the high‐resolution X‐ray images under broad energy range (20–160 keV) are realized on both single‐pixel and linear scanning mode, thus holding huge potential for medical diagnosis, safety inspection, and outer space detection.

AbstractPM6 is a widely used D–A copolymer donor in the polymer solar cells (PSCs). Incorporating second electron‐withdrawing (A2) units into PM6 backbone by ternary D–A1–D–A2 random copolymerization strategy is an effective approach to further improve its photovoltaic performance. Here, the authors synthesize the PM6‐based terpolymers by introducing thiazolothiazole as the A2 units connecting with thiophene π‐bridges attaching alkyl substituent towards the A2 unit (PMT‐CT) or towards D‐unit (PMT‐FT), and study the effect of the alkyl substituent position on the photovoltaic performance of them. Two terpolymers PMT‐FT‐10 and PMT‐CT‐10 are obtained by incorporating 10% A2 units in the terpolymers. The film of PMT‐CT‐10 shows slightly up‐shifted highest occupied molecular orbital (HOMO) energy levels while better co‐planar structure than that of PMT‐FT‐10. Meanwhile, the PMT‐CT‐10:Y6 blend film exhibits better molecular packing properties, more proper phase separation and more balanced hole and electron mobilities, which are beneficial to more efficient exciton dissociation, efficient charge transport and weaker bimolecular recombination. Consequently, the PMT‐CT‐10 based PSCs obtain the highest power conversion efficiency of 18.21%. The results indicate that side chain position on the thiophene π‐bridges influence the device performance of the terpolymer donors, and PMT‐CT‐10 is a high efficiency polymer donor for the PSCs.

AbstractOwing to the moderate redox potential and high safety, Zn metal anodes have been garnering great attention. However, the poor reversibility and limited‐service period caused by side reactions and dendrites hinder their applications. Here, a novel anode material consisting of a hexagonal 1T‐Vanadium diselenide (1T‐VSe2) film on graphene is developed as a zincophilic template to epitaxially electrodeposit hexagonal closest packed Zn to replace the conventional metal substrates in Zn batteries. The 1T‐VSe2/Zn anode induces a horizontally (002)‐oriented plate‐like Zn crystal deposition morphology instead of randomly oriented grains that prompts the compact Zn deposition. According to density functional theory calculations, the VSe2 substrate exhibits a higher Zn adsorption (−0.54 eV) than the graphene (−0.38 eV) or neat Zn (−0.48 eV) counterparts, leading to the enhanced zincophilicity and a lower nucleation overpotential, in agreement with the experimental results. The force field‐based molecular dynamics simulations visualize Zn nucleation and morphological evolution at the atomistic level. The rapid adatom diffusion on VSe2 leads to layer‐by‐layer Zn electrodeposits with higher fraction of the (002) facets to effectively prohibit dendrite formation. The symmetric cell with 1T‐VSe2/Zn delivers an ultra‐stable cyclic life of 2500 h with 50 mV overpotential at 1 mA cm−2 and 1 mAh cm−2.
Selection on early survival does not explain germination rate clines in Mimulus cardinalis
Authors: Muir Christopher D. , Van Den Elzen Courtney L. , Angert Amy L. 
Published: November 2022

AbstractPremiseMany traits covary with environmental gradients to form phenotypic clines. While local adaptation to the environment can generate phenotypic clines, other nonadaptive processes may also. If local adaptation causes phenotypic clines, then the direction of genotypic selection on traits should shift from one end of the cline to the other. Traditionally, genotypic selection on non‐Gaussian traits like germination rate have been hampered because it is challenging to measure their genetic variance.MethodsHere we used quantitative genetics and reciprocal transplants to test whether a previously discovered cline in germination rate showed additional signatures of adaptation in the scarlet monkeyflower (Mimulus cardinalis). We measured genotypic and population level covariation between germination rate and early survival, a component of fitness. We developed a novel discrete log‐normal model to estimate genetic variance in germination rate.ResultsContrary to our adaptive hypothesis, we found no evidence that genetic variation in germination rate contributed to variation in early survival. Across populations, southern populations in both gardens germinated earlier and survived more.ConclusionsSouthern populations have higher early survival but it is not caused by faster germination. This pattern is consistent with nonadaptive forces driving the phenotypic cline in germination rate, but future work will need to assess whether there is selection at other life stages. This statistical framework should help expand quantitative genetic analyses for other waiting‐time traits.
Putting the system in systemic racism: A systems thinking approach to advancing equity
Authors: Watson Erin R. , Collins Charles R. 
Published: November 2022

AbstractGenerations of scholars and activists have argued that racial inequities emerge not only because of racist ideologies but also from a hierarchical system of racial oppression. This theoretical tradition has highlighted numerous ways in which systemic racism manifests itself, from racist policies to differential access to material conditions and power. However, given that by definition systemic racism is focused on systems, theories of systemic racism would be more comprehensive and actionable by drawing on scholarship related to systems thinking. Systems thinking is a conceptual orientation that aims to understand how different types of systems function over time. This paper builds on the work of previous scholars to propose a systems thinking approach to understand and strategically disrupt racist systems. We provide a typology of system characteristics (organized into the categories of paradigms, structures, elements, and feedback loops) that together can be used to help understand the operation of systemic racism in different system contexts. The paper also provides an approach to identify and strategically target multiple system leverage points to simultaneously disrupt the status quo of racial inequity and promote the emergence of conditions enabling racial equity. This systems thinking approach can be used to guide learning and action within an ongoing process of antiracist praxis.

Published: November 2022

AbstractThe high‐performance polymer para‐aramid (PPTA) is discovered to gel too soon during the polymerization process, resulting in poor processing performance. In this work, a homogeneous polymer solution containing heterocyclic para‐aramid (HPPTA) was successfully synthesized by introducing 2,4‐aminophenyl‐5‐aminobenzimidazole groups into the molecular chains of PPTA, and then HPPTA aerogel was prepared using a supercritical drying technique that took advantage of the HPPTA solution's excellent property of slow gelation. When the HPPTA polymer mass fraction was 1 wt%, the aerogel had the lowest density of 0.086 g cm−3 with a BET specific surface area of 376.59 m2 g−1. The HPPTA‐2 aerogel had better adsorption performance for anionic dye methyl orange, with a maximum adsorption capacity of 319.47 mol g−1; however, its adsorption capacity for cationic dye methylene blue and neutral dye dimethyl yellow was very low, at only 19.68 and 0 mol g−1, respectively. The selective adsorption ability of HPPTA aerogel made it a simple and scalable platform for removing anionic dyes from water solutions. Furthermore, the HPPTA aerogel has outstanding thermal properties for thermal insulation applications in severe environments due to the synergistic effect of the 3D porous structure inside the aerogel and the exceptional thermal stability of the HPPTA.
Development of a single subfloor plate for a light cargo vehicle in sandwich construction
Authors: Scheibe Sebastian , Kriescher Michael 
Published: November 2022

AbstractThe Institute for Vehicle Concepts of the German Aerospace Center is developing new concepts for very light vehicles. One of these concepts is a light freight vehicle for urban logistics. The complete chassis is designed as a sandwich structure. Challenges in using these sandwich structures are the introduction of loads and joining technology. Additionally, the structure should be easy and efficient to produce. This leads to the question, if it is possible to use a single sandwich subfloor plate as the load‐bearing structure of this vehicle. As a solution, the implementation of through‐the‐thickness inserts, which are mounted in the production process of the sandwich structure are proposed. Validation with simulations will be presented and the production process of such structures will be illustrated.

Published: November 2022

AbstractYuanhuacine is a Daphne‐type diterpene ortho‐ester and is one of the main active ingredients of genkwa flos. Anticancer activity of yuanhuacine has been well investigated in various tumor cells and animal models, but information on metabolism and pharmacokinetics is limited. The aims of the present study were to investigate the metabolic and pharmacokinetic profiles of yuanhuacine in rat. The metabolic profile of yuanhuacine was obtained from rat plasma, urine, and feces using ultra‐high‐performance liquid chromatography‐quadrupole‐time‐of‐flight mass spectrometry. A total of seven metabolites were detected, and the proposed metabolic pathways involved oxidation and glucuronidation. A simple and sensitive ultra‐high‐performance liquid chromatography‐tandem mass spectrometry method was developed for the determination of yuanhuacine in rat plasma. The linear range of yuanhuacine was 1–1000 ng/ml (R2 = 0.998). The intra‐ and inter‐precision (coefficient of variation %) of the assay was 3.86–6.18% and 2.65–5.75%, respectively, and the intra‐ and inter‐accuracy (relative error %) was −3.83–4.77% and −3.03–5.11%, respectively. The extraction recovery, matrix effect, stability, and incurred sample reanalysis of yuanhuacine were within acceptable levels. The established method was validated and successfully applied to the preclinical pharmacokinetic study of yuanhuacine. The absolute oral bioavailability of yuanhuacine was calculated as 1.14%, and it reached the maximum plasma concentration of 28.21 ± 2.79 ng/ml in rat plasma at 2 h in the oral dosing group. The apparent volume of distribution of intravenous and intragastric administrations was 26.07 ± 6.45 and 21.83 ± 3.54 L/kg, respectively. The half‐life of elimination of yuanhuacine was 9.64 ± 1.53 h in the intravenous dosing group.
HSQC‐NMR‐based profiling approaches for raffinose family oligosaccharides in pulses
Authors: Fels Lea , Bunzel Mirko 
Published: November 2022

AbstractBackground and ObjectivesDue to insufficient resolution, 1H nuclear magnetic resonance (NMR) spectroscopy‐based methods are limited to quantify carbohydrates. In the past, heteronuclear single quantum coherence (HSQC)‐based methods were demonstrated to be superior as the second dimension greatly improves resolution. However, whether these experiments are also suitable to determine structurally similar oligosaccharides such as raffinose family oligosaccharides (RFO) still needs to be demonstrated.FindingsBy optimizing NMR parameters, well resolved signals for the analysis of glucose, fructose, galactose, sucrose and the RFO raffinose, stachyose, and verbascose were identified. Application of fast HSQC methods in combination with nonuniform sampling enables analyses of sucrose and RFO in pulses (blue lupin seeds, red lentils, kidney beans) within 24 min. If the analytes are present at levels greater than 0.5 g/100 g, HSQC‐based methods provide data equivalent to an anion‐exchange chromatography‐based reference method.ConclusionsHigh resolution fast HSQC‐based approaches are suitable tools to analyze complex carbohydrate mixtures as demonstrated for RFO in different pulses.Significance and NoveltyFast HSQC experiments were applied for the first time to analyze structurally similar oligosaccharides. In the future, this approach will be a most valuable tool to analyze complex mixtures of carbohydrates in food products.
