Published: October 2024

AimsThe influence of metabolic syndrome (MetS) on the outcome after hip and knee arthroplasty is debated. We aimed to investigate the change in patient-reported outcome measure (PROM) scores after hip and knee arthroplasty, comparing patients with and without MetS.MethodsFrom 1 May 2017 to 30 November 2019, a prospective cohort of 2,586 patients undergoing elective unilateral hip and knee arthroplasty was established in Denmark. Data from national registries and a local database were used to determine the presence of MetS. Patients’ scores on Oxford Hip Score (OHS) or Oxford Knee Score (OKS), EuroQol five-dimension five-level questionnaire (EQ-5D-5L), University of California, Los Angeles (UCLA) Activity Scale, and Forgotten Joint Score (FJS) at baseline, three, 12, and 24 months after surgery were collected. Primary outcome was the difference between groups from baseline to 12 months in OHS and OKS. Secondary outcomes were scores of OHS and OKS at three and 24 months and EQ-5D-5L, UCLA Activity Scale, and FJS at three, 12, and 24 months after surgery. Generalized linear mixed model was applied, adjusting for age, sex, Charlson Comorbidity Index, and smoking to present marginal mean and associated 95% CIs.ResultsA total of 62.3% (1,611/2,586) of the cohort met the criteria for MetS. Both groups showed similar increase in mean OHS (MetS group 22.5 (95% CI 21.8 to 23.1), non-MetS group 22.1 (21.3 to 22.8); p = 0.477) and mean OKS (MetS group 18.0 (17.4 to 18.6), non-MetS group 17.8 (17.0 to 18.7); p = 0.722) at 12 months' follow-up. Between groups, similar improvements were seen for OHS and OKS at three and 24 months postoperatively and for the mean EQ-5D-5L, EuroQol-visual analogue scale (EQ-VAS), UCLA Activity Scale, and FJS at every timepoint.ConclusionPatients meeting the criteria for MetS obtain the same improvement in PROM scores as individuals without MetS up to 24 months after hip and knee arthroplasty. This is important for the clinician to take into account when assessing and advising patients with MetS.Cite this article: Bone Joint J 2024;106-B(10):1074–1083.

Published: October 2024

AimsThe aim of this study was to evaluate the outcome of complex radial head fractures at mid-term follow-up, and determine whether open reduction and internal fixation (ORIF) or radial head arthroplasty (RHA) should be recommended for surgical treatment.MethodsPatients who underwent surgery for complex radial head fractures (Mason type III, ≥ three fragments) were divided into two groups (ORIF and RHA) and propensity score matching was used to individually match patients based on patient characteristics. Ultimately, 84 patients were included in this study. After a mean follow-up of 4.1 years (2.0 to 9.5), patients were invited for clinical and radiological assessment. The Mayo Elbow Performance Score (MEPS), Oxford Elbow Score (OES), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire score were evaluated.ResultsPatients treated with ORIF showed significantly better postoperative range of motion for flexion and extension (121.1° (SD 16.4°) vs 108.1° (SD 25.8°); p = 0.018). Postoperative functional scores also showed significantly better results in the ORIF group (MEPS 90.1 (SD 13.6) vs 78 (SD 20.5); p = 0.004). There was no significant difference between the groups in terms of the complication rate (RHA 23.8% (n = 10) vs ORIF 26.2% (n = 11)). Implant-related complications occurred in six cases (14.3%) in the RHA group and in five cases (11.9%) in the ORIF group.ConclusionIrrespective of the patient’s age, sex, type of injury, or number of fracture fragments, ORIF of the radial head should be attempted initially, if a stable reconstruction can be achieved, as it seems to provide a superior postoperative outcome for the patient compared to primary RHA. If reconstruction is not feasible, RHA is still a viable alternative. In the surgical treatment of complex radial head fractures, reconstruction shows superior postoperative outcomes compared to RHA. Good postoperative results can be achieved even after failed reconstruction and conversion to secondary RHA. Therefore, we encourage surgeons to favour reconstruction of complex radial head fractures, regardless of injury type or number of fragments, as long as a stable fixation can be achieved.Cite this article: Bone Joint J 2024;106-B(10):1158–1164.

Published: October 2024

AimsThis study aimed to assess the risk of acute kidney injury (AKI) associated with combined intravenous (IV) and topical antibiotic therapy in patients undergoing treatment for periprosthetic joint infections (PJIs) following total knee arthroplasty (TKA), utilizing the Kidney Disease: Improving Global Outcomes (KDIGO) criteria for classification.MethodsWe conducted a retrospective analysis of 162 knees (162 patients) that received treatment for PJI post-TKA with combined IV and topical antibiotic infusions at a single academic hospital from 1 January 2010 to 31 December 2022. The incidence of AKI was evaluated using the KDIGO criteria, focussing on the identification of significant predictors and the temporal pattern of AKI development.ResultsAKI was identified in 9.26% (15/162) of the cohort, predominantly presenting as stage 1 AKI, which was transient in nature and resolved prior to discharge. The analysis highlighted moderate anaemia and lower baseline serum creatinine levels as significant predictors for the development of AKI. Notably, the study found no instances of severe complications such as wound dehiscence, skin erosion, or the need for haemodialysis following treatment.ConclusionThe findings suggest that the combined use of IV and topical antibiotic therapy in the management of PJIs post-TKA is associated with a low incidence of primarily transient stage 1 AKI. This indicates a potentially favourable renal safety profile, advocating for further research to confirm these outcomes and potentially influence treatment protocols in PJI management.Cite this article: Bone Joint Res 2024;13(10):525–534.
Analysis of a Combined Spherical Harmonics and Discontinuous Galerkin Discretization for the Boltzmann Transport Equation
Authors: Assogba Kenneth , Allaire Grégoire , Bourhrara Lahbib 
Published: October 2024

AbstractIn [L. Bourhrara, A new numerical method for solving the Boltzmann transport equation using the PN method and the discontinuous finite elements on unstructured and curved meshes, J. Comput. Phys. 397 2019, Article ID 108801], a numerical scheme based on a combined spherical harmonics and discontinuous Galerkin finite element method for the resolution of the Boltzmann transport equation is proposed. One of its features is that a streamline weight is added to the test function to obtain the variational formulation. In the present paper, restricting our attention to the advective part of the Boltzmann equation, we prove the convergence and provide error estimates of this numerical scheme. To this end, the original variational formulation is restated in a broken functional space. The use of broken functional spaces enables to build a conforming approximation, that is the finite element space is a subspace of the broken functional space. The setting of a conforming approximation simplifies the numerical analysis, in particular the error estimates, for which a Céa’s type lemma and standard interpolation estimates are sufficient for our analysis. For our numerical scheme, based onℙk{\mathbb{P}^{k}}discontinuous Galerkin finite elements (in space) on a mesh of sizehand a spherical harmonics approximation of orderN(in the angular variable), the convergence rate is of order𝒪⁢(N-t+hk){\mathcal{O}(N^{-t}+h^{k})}for a smooth solution which admits partial derivatives of orderk+1{k+1}andtwith respect to the spatial and angular variables, respectively. Fork=0{k=0}(piecewise constant finite elements) we also obtain a convergence result of order𝒪⁢(N-t+h12){\mathcal{O}(N^{-t}+h^{\frac{1}{2}})}. Numerical experiments in one, two and three dimensions are provided, showing a better convergence behavior for theL2{L^{2}}-norm, typically of one more order,𝒪⁢(N-t+hk+1){\mathcal{O}(N^{-t}+h^{k+1})}.
Determination of total hardness of water sample by titration using double burette method: an economical approach
Authors: Dhoke Shailesh K. 
Published: October 2024

Abstract
Titration is one of the most prevalent methods practice in almost all laboratories. Worldwide every curriculum for science and engineering undergraduate students has titrations included in their laboratory sessions. However, there are few drawbacks associated with it when it comes to chemical discharge and cost due to excess consumption of titrants, titrand and related chemicals during titration. Further, the method is an exhaustive time consuming process. In present study, conventional titration method using single burette used for determination of total hardness of water has been explored in different perspective by adopting a double burette method approach. Based on a comparative laboratory study it was found that a double burette method is not only safer and faster but also relatively more economical.

AbstractBackground and objectiveAs a last option, multidrug-resistant Gram-negative infections (caused by Enterobacteriaceae) are treated with the antibiotic colistin, also known as polymyxin E. Colistin-resistant superbugs predispose people to untreatable infections, possibly leading to a high mortality rate. This project aims to study the effect ofAcacia niloticaaqueous extract and zinc oxide nanoparticles (ZnO-NPs) on colistin-resistantKlebsiella pneumonia(CRKP).Materials and methodsZnO-NPs were synthesized using the green method and characterized by UV-vis, Fourier transform infrared spectroscopy, and X-ray diffraction. The zone of inhibition (ZI) was measured using the agar-well diffusion method, and the minimum inhibitory concentration (MIC) and minimum bactericidal concentration were estimated to determine the antimicrobial activity of the tested compound. Scanning electron microscopy (SEM) and transmission electronic microscopy (TEM) were used to investigate the alterations in bacterial cells that were treated with the tested drugs.ResultsThe synthesized ZnO-NPs presented good chemical and physical properties, and the plant extract and ZnO-NPs displayed a large ZI. ZnO-NPs had the lowest MIC (0.2 mg·mL−1). SEM and TEM observations revealed various morphological modifications in CRKP cells, including cell shrinkage, cell damage, cytoplasm loss, cell wall thinning, and cell death.ConclusionA. niloticaaqueous extract and ZnO-NPs could be used as alternative natural products to produce antibacterial drugs and to prevent CRKP infection.
Jenseits von Eden. Der Traum vom alternativen Leben und die Mission der Siedlungsbewegung im Deutschen Kaiserreich
Authors: Homberg Michael 
Published: October 2024

Zusammenfassung
Im wilhelminischen Kaiserreich reiften neue, alternative Konzepte eines Siedlungskolonialismus im In- und Ausland aus dem Geiste der „Lebensreform“. Dabei regte der Traum vom besseren Leben, der unter dem Slogan „zurück zur Natur“ die sozialen Utopien der vielgestaltigen Reformbewegungen der Jahrhundertwende vitalisierte, die Gründung diverser Musterkolonien vor den Toren Berlins, an den Grenzen des Reiches und in Übersee an. Ausgehend von dieser Erkenntnis nimmt der Artikel die verschiedenen Stränge der diskursiven Verhandlung zeitgenössischer Konzepte des „Siedelns“ und der „(inneren) Kolonisation“ in der Epoche des imperialen Kolonialismus in den Blick und untersucht die sozialen, ökonomischen und politischen Rahmungen der Siedlungsexperimente an der Schwelle des 20. Jahrhunderts. Er geht von der These aus, dass die Ziele der alternativen Siedlungsbewegungen und ihre gelebten Utopien einer Lebens-, Boden- und Wirtschaftsreform viel stärker als bislang in den Kontexten kolonialpolitischer Visionen und Ambitionen gelesen werden müssen. Damit leistet der Artikel, an der Schnittstelle zwischen Kolonialgeschichte und politischer Kulturgeschichte, einen Beitrag zum besseren Verständnis der in der Hochmoderne einsetzenden, (trans-)national verwobenen Siedlungsbewegungen und ermöglicht zugleich einen neuen Blick auf die komplexen, indes nach wie vor wenig beleuchteten Verbindungen zwischen der Kolonialbewegung und den Bewegungen der Lebens­erneuerung im Kaiserreich.

Published: October 2024

Abstract
Microgrids are a growing segment of the energy industry, representing a paradigm shift from remote central station power plants toward more localized, distributed generation. An efficient energy management structure is essential for a DC Microgrid with a PV system combined with a Hybrid Energy Storage System (HESS) of Battery and Supercapacitor. The combined supercapacitor and battery storage system provides a quick control for the DC-link voltage. It stabilizes the system and helps achieve smooth PV power delivery to loads. The boost converter used for the PV system is controlled by a Maximum Power Point Tracking (MPPT) method to extract maximum power and maintain a constant voltage at the DC bus despite the daily change in solar power. The boost-buck converter is used to control the charging and discharging processes of the BESS to maintain a constant voltage at the DC bus. To achieve the seamless operation of DC Microgrid with HESS during the power fluctuations, this work proposes power coordination and control scheme has been proposed. To analyse the performance and efficacy of the proposed DC Microgrid with HESS are implemented in MATLAB/SIMULINK.
From Hindsight to Foresight: Understanding and Overcoming Bias in Financial Forecasts
Authors: Zweig Derek , Sumner Timothy , Luke Adam 
Published: October 2024

Abstract
This study conducts a comprehensive benchmarking analysis on analyst forecasts of revenue and EBITDA for exchange-traded public companies in the U.S. spanning the period from 2009 to 2022. Our findings reveal a consistent and statistically significant upward bias present in both revenue and EBITDA forecasts, on average, as evidenced by various measures of forecast error. This bias is explored at both market sector and market-wide levels of aggregation to check for macro-consistency. Recognizing the significance of these biases, we propose bias-adjustment frameworks aimed at enhancing the accuracy of future analyst forecasts pertaining to revenue and EBITDA. The implications of our study underscore the importance of mitigating such biases for improved forecasting precision in financial markets.
Nenghai: A Perspective from Han-Tibetan Cultural Interaction
Authors: Guang De 
Published: October 2024

Abstract
Nenghai 能海, a distinguished patriotic monk in the history of modern Chinese Buddhism, made remarkable contributions to the revitalization of Han Buddhism and the promotion of Han-Tibetan cultural exchanges. He journeyed to Xizang twice, studying under Khang Gsar Rinpoche 康萨仁波切 (1890–1941) and mastering both the exoteric and esoteric teachings of Buddhism. Upon his return to the Han regions of China, he founded “the Great Prajñāpāramitā Sect 大般若宗”, guiding disciples through Tibetan Lamrim and managing monasteries according to Han traditions, thereby adeptly propagating the integrated teachings of exoteric and esoteric Buddhism. During times of national turmoil and ethnic crises, he strove to revive the declining influence of Buddhism, fearlessly persevering against adversities. His efforts significantly contributed to preserving the integrity of Buddhist doctrines in China and fostering the diversity and prosperity of various Buddhist sects.

Noun classes, variation, and creativity in youth language practices in Zimbabwe and Tanzania
Authors: Hollington Andrea 
Published: October 2024

Abstract
While classical accounts of Bantu linguistics often depict noun classes as an inherent feature of nouns, more recent studies show there is greater variation in the use of noun classes, especially in terms of their discursive and pragmatic context. Youth language practices, often characterized by creativity and conscious changes, are of particular interest in this regard. This paper explores whether Bantu youth language practices exhibit conscious variation in their noun class systems and agreement. I discuss data from Bantu-based youth language practices in Southern and Eastern Africa, especially Lugha ya mtaani (Tanzania) and S’ncamtho (Zimbabwe), looking at noun classes and agreement. The paper features a short discussion of variation in noun class usage in Bantu languages in general, including insights into relevant aspects such as information structure, the use of loan words, noun classes in multilingual or translanguaging situations, and semantics. The latter is particularly important, as speakers can make conscious use of noun classes as part of contextualized meaning making processes that reflect semantic nuances and stylistic choices. The objective of this contribution is to highlight the role of semantics and conscious meaning making in the choice of grammatical devices and the manifestations of microvariation in youth language practices.
Don’t Tell Me to Have, but to Do It! The Role of Luxury Desirability Motives in Reducing Counterfeiting Schadenfreude
Authors: Khan Sameeullah , Fazili Asif Iqbal , Bashir Irfan 
Published: October 2024

Abstract
This paper postulates that consumers’ desire for doing-luxury – pursuing luxury with the intention of acquiring a life experience (vs. having-luxury) – pursuing luxury with the intention of acquiring a material good reduces counterfeiting schadenfreude – consumers’ feelings of pleasure from the losses of luxury brands due to counterfeiting. Two experiments employed various methods of invoking doing-luxury (vs. having-luxury) – actual product exposure and brand positioning to test the predicted framework. The results demonstrate that doing-luxury (vs. having-luxury) leads to a lower counterfeiting schadenfreude; an effect explained by the lower perceived similarity. This research makes an important contribution to the counterfeiting and experiential marketing literature by demonstrating the role of brand positioning in reducing a critical counterfeit-related social emotion. The results also validate the relevance of the intentions-based distinction of experiential versus material purchases in predicting counterfeiting schadenfreude. To reduce counterfeiting schadenfreude, luxury brands must signal an ephemeral image focusing on moments of luxury rather than functions of luxury. In addition, ad appeals must invoke sensory elements, feelings, emotions, imagination, and mental stimulation rather than the hard facts about the products per se.
Transformation on the Rocks
Authors: Patel Kiran Klaus 
Published: October 2024

Abstract
Der Kir Royal, ein Modegetränk der 1980er Jahre, dient hier als Aufhänger und Sonde, um zentrale Probleme der Geschichte der heutigen Europäischen Union aus den letzten vier Dekaden zu erörtern. Kiran Klaus Patel vertritt die These, dass bereits kurz vor Ende des Kalten Kriegs eine grundlegende Transformation des Einigungsprozesses einsetzte. Vor diesem Hintergrund entwickelt der Autor eine multiperspektivische Forschungsagenda, die besonders darauf zielt, die Integrationsgeschichte stärker mit allgemeinen Fragen der europäischen Zeitgeschichte zu verknüpfen. Jenseits teleologischer und triumphalistischer Entwürfe trägt der Aufsatz so auch zu einer Genealogie gegenwärtiger Problemlagen bei.
Zwischen Politik und Wissenschaft

Abstract
Robert Obermair beleuchtet die Flucht des österreichischen Nationalsozialisten Oswald Menghin nach Südamerika sowie seine Integration in Argentinien. Er lenkt den Fokus dabei insbesondere auf Menghins zweite Karriere als Wissenschaftler in Buenos Aires. In diesem Zusammenhang nimmt der Autor die Entnazifizierung des Wissenschaftssektors in Österreich in den Blick und untersucht, wie sich der Umgang der Behörden mit dem zunächst polizeilich gesuchten Wissenschaftler, aber auch dessen Vernetzung im politischen und wissenschaftlichen Milieu in Europa auf seine zweite Karriere in Südamerika auswirkten. Am Beispiel Oswald Menghins werden so die transnationalen Verflechtungen zwischen Politik und Wissenschaft in der Nachkriegszeit sichtbar.
Monitoring urban growth and landscape fragmentation in Kaduna, Nigeria, using remote sensing approach
Authors: Musa Kabir , Abubakar Muhammad Lawal 
Published: October 2024

This study assessed urban growth in Kaduna using remote sensing indices, landscape metrics, and Landsat images (2003, 2013, and 2023). Land use/land cover was carried out using the decision tree algorithm, while the transition matrix was computed using ArcGIS 10.8. Landscape fragmentation was assessed using Fragstat 4.3. The results revealed that between 2003 and 2023, bare land, built-up areas, and water bodies increased by 596 km2, 121.04 km2, and 0.22 km2, respectively, while cultivated land and tree cover decreased by 525.54 km2 and 191.91 km2, respectively. For the rate of change, bare lands, built-up areas, and water bodies increased by 29.81 km2, 6.05 km2, and 0.01 km2 annually, respectively, while cultivated lands and water bodies decreased by 26.28 km2 and 9.60 km2, respectively. For the land-use transition, 112.71 km2 of the built-up areas remained persistent. Cultivated lands, tree cover, and water bodies transitioned to built-up areas, losing 85.43 km2, 13.91 km2, and 0.91 km2, respectively. Landscape fragmentation analysis revealed that the number of patches increased from 405 in 2003 to 614 in 2023. Patch density, largest patch index, total edge, edge density, area-weighted mean shape index, and fractal dimension index decreased between 2003 and 2013 but increased between 2013 and 2023, indicating urban sprawl. However, the area-weighted mean contiguity index consistently increased between 2003 and 2023. The study concluded that urbanization is the leading driver of landscape fragmentation. This study recommends that development should be controlled to reduce encroachment on agricultural lands and habitats, thereby reducing landscape fragmentation and land degradation.
