Authors: Du Yi , Wu Chengfei , Wang Chenghu , Yuan Guiqiang , Ouyang Shiyuan , Liao Jie , An Yifei 
Published: December 2023

The stress background and rock fractures are essential factors affecting the stability of mines. In order to better understand the in situ stress background and rock fractures in the Guangdong Fankou Mine, we use ultrasonic borehole television scanning to measure rock fractures. The results indicate that rock fractures are intensively distributed at depths of −360 m to −450 m below the surface, suggesting the effect of intensive mining activities. The present maximum horizontal principal stress direction is NWW, which is consistent with the regional tectonic stress field direction. Systematic measurement of rock fractures is fundamental for further three-dimensional geological modeling and is significant for mining engineering.
Experimental research on the effect of graphite on heat transfer performance of a latent heat storage system
Authors: Zhao Yuanyuan , Li Guang , Zhang Xinzhi , Wu Hongqiang 
Published: December 2023

Phase change materials (PCMs) provide a good resolution for the latent heat storage system which can be used in many application fields such as solar energy utilization and waste heat recovery. This study aims to experimentally investigate the impact of graphite powder on the thermal characteristics and heat transfer performance of paraffin with ceresin (PC) as a PCM, using water as the heat transfer fluid. Experimental tests were conducted to analyze the heat transfer performance of PC and the influence of graphite powder on its thermal characteristics. Different masses of graphite powder were employed to assess their effects on the heating rate and the time required for PC to reach its melting temperature. The experimental results revealed that the addition of graphite powder improved the heating rate of both PC and water, attributed to its high thermal conductivity. Furthermore, the time for PC to reach the melting temperature was decreased with varying amounts of graphite powder, achieving a maximum reduction of 17.2% with the addition of 40 g of graphite powder. However, the effectiveness of graphite powder in enhancing heat transfer efficiency was found to be limited, with the optimal promotion effect observed at around 40 g of graphite powder for 500 g of PC. The findings of this investigation provide valuable insights for the design of phase change energy storage systems, with potential applications including heat pump drying units, greenhouse energy storage in modern agriculture, and solar energy storage utilization technology. The theoretical basis established can contribute to the development and optimization of PCM-based systems in diverse practical scenarios.

Published: December 2023

Background: Vancomycin dosing is difficult in critically ill patients receiving continuous renal replacement therapy (CRRT). Previous population pharmacokinetic (PopPK) models seldom consider the effect of residual diuresis, a significant factor of elimination, and thus have poor external utility. This study aimed to build a PopPK model of vancomycin that incorporates daily urine volume to better describe the elimination of vancomycin in these patients.Methods: We performed a multicenter retrospective study that included critically ill patients who received intermittent intravenous vancomycin and CRRT. The PopPK model was developed using the NONMEM program. Goodness-of-fit plots and bootstrap analysis were employed to evaluate the final model. Monte Carlo simulation was performed to explore the optimal dosage regimen with a target area under the curve of ≥400 mg/L h and 400–600 mg/L h.Results: Overall, 113 observations available from 71 patients were included in the PopPK model. The pharmacokinetics could be well illustrated by a one-compartment model with first-order elimination, with the 24-h urine volume as a significant covariate of clearance. The final typical clearance was 1.05 L/h, and the mean volume of distribution was 69.0 L. For patients with anuria or oliguria, a maintenance dosage regimen of 750 mg q12h is recommended.Conclusion: Vancomycin pharmacokinetics in critically ill patients receiving CRRT were well described by the developed PopPK model, which incorporates 24-h urine volume as a covariate. This study will help to better understand vancomycin elimination and benefit precision dosing in these patients.
Development and Assessment of a 4D Printing Technique for Space Applications
Authors: Richter Tim , Völlmecke Christina 
Published: December 2023

Shape memory polymers (SMPs), a class of polymers exhibiting the unique ability to restore deformation induced during the programming process in response to external stimuli, have garnered significant attention. In this study, our objectives were two-fold: to develop an efficient device for programming SMP hinges crafted from polyetheretherketon (PEEK) and to optimize their performance for potential utilization in space applications. Two versions of the programming device were constructed and compared. Through three systematic experiments, we identified optimal programming and recovery conditions for the hinges, revealing the best shape memory effects (SMEs) at a programming temperature of 250 °C. Remarkably, the hinges were able to recover the previously induced deformation up to 100%, maintaining functionality down to a lower temperature limit of 150 °C. Notably, these hinges demonstrated a wide operational range of over 180°, rendering them promising for space applications, as extensively discussed within the manuscript. However, challenges arise due to the high recovery temperature of 150 °C, presenting obstacles in achieving optimal functionality in the demanding conditions of a space environment.

Published: December 2023

The bacterial stem blight of alfalfa (Medicago sativa L.), first reported in the United States in 1904, has emerged recently as a serious disease problem in the western states. The causal agent, Pseudomonas syringae pv. syringae, promotes frost damage and disease that can reduce first harvest yields by 50%. Resistant cultivars and an understanding of host-pathogen interactions are lacking in this pathosystem. With the goal of identifying DNA markers associated with disease resistance, we developed biparental F1 mapping populations using plants from the cultivar ZG9830. Leaflets of plants in the mapping populations were inoculated with a bacterial suspension using a needleless syringe and scored for disease symptoms. Bacterial populations were measured by culture plating and using a quantitative PCR assay. Surprisingly, leaflets with few to no symptoms had bacterial loads similar to leaflets with severe disease symptoms, indicating that plants without symptoms were tolerant to the bacterium. Genotyping-by-sequencing identified 11 significant SNP markers associated with the tolerance phenotype. This is the first study to identify DNA markers associated with tolerance to P. syringae. These results provide insight into host responses and provide markers that can be used in alfalfa breeding programs to develop improved cultivars to manage the bacterial stem blight of alfalfa.
My Soul Looks Beyond in Wonder: Curating Faith, Freedom, and Futurity at the National Museum of African American History and Culture
Authors: McCormack Michael Brandon 
Published: December 2023

This article offers a description and critical reflection upon two recent exhibits on display at the National Museum of African American History and Culture (NMAAHC): Spirit in the Dark: Religion in Black Music, Activism, and Popular Culture and Afrofuturism: A History of Black Futures. The article explores the interplay of mutually reinforcing themes of faith, freedom, and futurity that emerge when examining the exhibits together. This article also demonstrates the public significance of the curation of religion and culture in museums and other cultural spaces beyond the academy and religious institutions. It further shows how religion becomes a site of critical meditation upon and creative manifestation or materialization of Black futures. As such, this article contributes to more expansive discourses on the interplay between Black studies and the study of religion.
El estatuto de la poesía en la ensayística de Samuel Beckett y T.S. Eliot
Authors: Lasa Cecilia 
Published: December 2023

Este trabajo se propone estudiar la ensayística de Samuel Beckett y de T. S. Eliot como espacio de reflexión sobre su composición poética. Ambos poetizan la crisis del lenguaje y de las formas literarias heredadas del siglo XX en un contexto signado por enfrentamientos bélicos armados y encuentran en el ensayo el género que les permite construir una base conceptual en torno a su quehacer artístico: cuál es la naturaleza, la función y el estatuto del lenguaje poético, cuál es la concepción de poesía que se despliega en sus poemas, entre otras teorizaciones. No obstante, los autores difieren en el tratamiento que hacen del ensayo como forma: el escritor irlandés explora, desde el humor y con una actitud lúdica, la hibridez del género al emplear para su composición procedimientos propios del teatro y de la poesía; el escritor norteamericano-inglés, por su parte, hace un uso instrumental del género, funcional a su quehacer poético, y no convierte a su producción ensayística en objeto de experimentación poética. En este sentido, mientras que para T. S. Eliot la poesía se manifiesta en sus ensayos principalmente como contenido sobre el cual teorizar, para Beckett el ensayo constituye una expresión discursiva que, tanto como el teatro, puede convertirse en objeto de poetización.
Hilemorfismo y generación natural en el Comentario de Tomás de Aquino a la Metafísica de Aristóteles
Authors: Iversen Francisco 
Published: December 2023

En el momento de mayores precisiones sobre la sustancia primera, Metafísica VII es un libro complejo que nuclea numerosos problemas metafísicos y lógicos de la tradición aristotélica. Aparecen allí, por ejemplo, el problema de la unidad de la metafísica, el hilemorfismo, el problema de la ousía primera, el problema del contenido de la definición, etc. En especial, los capítulos 7 a 9 tienen pasajes misteriosos donde se desvía el foco de la discusión que venía dándose en el libro, en tanto abordan los tipos de generación. Asimismo, el análisis hilemórfico de la generación natural que ahí aparece es central para comprender la génesis humana en Aristóteles y la tradición que lo sigue. Ahora bien, en el Comentario a la Metafísica de Tomás de Aquino todo lo antes mencionado toma dimensión y se resignifica a cuento de las discusiones escolásticas.
La propuesta de este trabajo tiene dos partes. La primera aspira a leer el análisis de la generación natural en dichos capítulos de la obra aristotélica: con el objetivo de determinar: (i) las notas propias de la doctrina hilemórfica allí presentada; (ii) sus implicancias (a) para con el problema de compatibilizar la noción de ousía de las Categorías y la Metafísica y, (b) para con el problema del contenido de la definición. En segundo término, se analizarán las lectiones 6-8 del Comentario tomista para determinar la reconstrucción que Tomás hace de lo anterior y el impacto que aquello tiene sobre sus doctrinas

PROSPECTS FOR THE APPLICATION OF REED-SOLOMON CODES AN D GOLD SEQUENCES IN THE TASKS OF GUARANTEED DATA DELIVERY
Authors: Кукунин Д.С. 
Published: December 2023

Рассмотрены возможности недвоичных рекуррентных последовательностей, в основе которых лежат помехоустойчивые коды Рида-Соломона. Представляя их кодовые комбинации как аналоги последовательностей максимальной длины, можно обеспечить восстановление информационных блоков по любому их последовательному или децимированному участку. Такой подход значительно повышает вероятность доставки данных в пакетной сети при использовании транспортных протоколов, которые сами по себе не содержат механизмов гарантированной передачи информации.
The possibilities of non-binary recurrent sequences based on noise-resistant ReedSolomon codes are considered. By presenting their code combinations as analogs of maximum length sequences, it is possible to ensure the recovery of information blocks for any of their sequential or decimated sections. This approach significantly increases the probability of data delivery in a packet network when using transport protocols that themselves do not contain mechanisms for guaranteed information transmission.

Authors: Prucnal-Wójcik Marta 
Published: December 2023

RESEARCH OBJECTIVE: The article presents a comparative analysis of legal regulations in selected (according to the author’s research interests) European countries regulating issues related to state interference with the scope of parental authority/responsibility, the grounds for this interference and the forms of modification of parental rights and responsibilities.
THE RESEARCH PROBLEM AND METHODS: The author is looking for answers to questions: In what circumstances the interference of state authorities in the sphere of parental rights is possible/necessary? What form can such interference take in the laws of selected countries? Who has the right/obligation to request such interference? The author used the method of analysis of ad- equate legal provisions of selected countries.
THE PROCESS OF ARGUMENTATION: Analysing the provisions in force in the internal legislation of Poland, Hungary, Norway and Sweden, the author presented adopted legal solutions regulating issues related to the scope of interference with the parental responsibility/authority of the child’s parents in the event of its improper implementation.
RESEARCH RESULTS: The analysis of legal provisions regulating the issue of parental responsibilities indicates that each of the four legal systems examined provides for situations in which it is necessary for state authorities to interfere in the sphere of parental rights and responsibilities.
CONCLUSIONS RECOMMENDATIONS AND APPLICABLE VALUE OF RESEARCH: Presented considerations constitute a general overview of the regulations in force in individual countries and, as such, are only an introduction to in-depth reflection on the optimization of the subject scope of social policy.
