This paper discusses iconographic features of the deity or “demon” Medjed (Mḏd). The specific and unusual image of this character is only found during the 21st Dynasty and is unknown in the funerary art of the New Kingdom and Late Period. Only oneYe coffin and nine papyri are known in which the image of Medjed is depicted. Eight are in the context of Spell 17 of the Book of the Dead. In the text of Spell 17, Medjed is described in lines 71–72 of Grapow’s Urk. V Abschnitt 24. The “invisibility” of this “demon” is evidently the reason for his unusual iconography: Medjed has a conical shaped body, with human legs. Although he does not have a true head, his eyes are indicated, and he wears a belt. Equally the deity could be depicted as a figure covered entirely in a conical cover except for the eyes and feet, which are visible. This curious treatment can be understood as an attempt by Egyptian artists to depict an invisible being. Full article

This theoretical paper expands upon previous research and proposes a guide for promoting mathematical talk and play through shared book reading (SBR), with a focus on the home environment. Building on a previously developed classroom-based model, this article describes a design-based research approach to extend the guide to including diverse literary genres—such as narrative, informational, multicultural, and math-specific books in a home setting. Parent–child shared book-reading in authentic contexts can provide a rich platform for “math talk”, where references are made to mathematical words, concepts, and content, and may support children’s mathematical skills. SBR with quality children’s literature can play a promising role in motivating and engaging children’s interest and pleasure in both reading and mathematics. However, few studies have explored this with diverse literary genres in the home setting, as the main focus has been in the classroom and using books specifically written to teach math content such as counting or sorting books. The proposed guide provides direction and practical examples for fostering parent–child math talk and play activities that can be used to extend concepts covered during the SBR. The potential application of the SBR guide, and how it can encourage parent–child talk to support a full range of mathematical concepts, encourage home-preschool collaboration, promote effective SBR techniques, and facilitate parent–child conversations about math in new and confident ways is discussed.

Background: Hypertensive disorders of pregnancy (HDPs) are a major cause of maternal morbidity and mortality worldwide. Very little progress has been made in reducing HDP-related maternal deaths in low- and middle-income countries (LMICs), including South Africa, over the past decade. Aim: The aim of this study was to describe maternal deaths arising from HDPs at tertiary/quaternary hospital in Johannesburg, South Africa, with specific focus on maternal characteristics, management, timing of death, causes, and avoidable factors and to use the information to inform clinical practice. Methods: We conducted a retrospective review of patient clinical records covering the period 1 January 2015 to 31 December 2018. Data on maternal demographic and pregnancy characteristics, management, causes, and timing of death were extracted from the clinical records and transferred into a Microsoft Excel^® Spreadsheet and analysed using descriptive statistics. Results: During the study period, 70 maternal deaths were recorded, of which 23 (32.8%) were due to HDP-related complications. The majority of the maternal deaths, 20 (86.9%), occurred during the postpartum period, predominantly affecting Black African women, 23 (100%), with a median age of 27 years. Notably, 18 (78.2%) of the deceased had booked early and attended antenatal care (ANC). Eclampsia emerged as the most common final cause of death. Key avoidable factors included non-adherence to established protocols, particularly failure to initiate aspirin prophylaxis in at-risk women, as well as incorrect or inadequate administration of antihypertensive therapy and magnesium sulphate (MgSO₄) prophylaxis. Conclusions: HDP-related maternal deaths are largely preventable. They primarily result from poor quality of care due to a lack of adherence to evidence-based protocol. Full article

Book covers are often the first component seen before a reader engages with a book’s contents; therefore, careful consideration is given to the text and image features that constitute their design. This study investigates the effects of the presentation of verbal (text) and visual (image) features on memorability and aesthetic evaluation in the context of book covers. To this aim, 50 participants took part in a memory recognition task in which the same book cover information was encoded in a learning phase, and either text or image features from the book covers acted as an informational cue for memory recognition and aesthetic evaluations. Our results revealed that image features significantly aided memory performance more than text features. Image features that were rated more beautiful were not better recognized as a result. However, differences in memory performance were found in relation to familiarity and, in a non-linear fashion, the extent to which the book’s contents could be inferred from the image’s informational content. Additionally, reading behavior was not found to influence memory performance. These results are discussed with regard to the interplay of text and image informational cues on book cover perception and provide implications for future studies. Full article

Bimetals—materials composed of two metal components with dissimilar standard reduction–oxidation (redox) potentials—offer unique electronic, optical, and catalytic properties, surpassing monometallic systems. These materials exhibit not only the combined attributes of their constituent metals but also new and novel properties arising from their synergy. Although many reviews have explored the synthesis, properties, and applications of bimetallic systems, none have focused exclusively on iron (Fe)- and aluminum (Al)-based bimetals. This systematic review addresses this gap by providing a comprehensive overview of conventional and emerging techniques for Fe-based and Al-based bimetal synthesis. Specifically, this work systematically reviewed recent studies from 2014 to 2023 using the Scopus, Web of Science (WoS), and Google Scholar databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and was registered under INPLASY with the registration number INPLASY202540026. Articles were excluded if they were inaccessible, non-English, review articles, conference papers, book chapters, or not directly related to the synthesis of Fe- or Al-based bimetals. Additionally, a bibliometric analysis was performed to evaluate the research trends on the synthesis of Fe-based and Al-based bimetals. Based on the 122 articles analyzed, Fe-based and Al-based bimetal synthesis methods were classified into three types: (i) physical, (ii) chemical, and (iii) biological techniques. Physical methods include mechanical alloying, radiolysis, sonochemical methods, the electrical explosion of metal wires, and magnetic field-assisted laser ablation in liquid (MF-LAL). In comparison, chemical protocols covered reduction, dealloying, supported particle methods, thermogravimetric methods, seed-mediated growth, galvanic replacement, and electrochemical synthesis. Meanwhile, biological techniques utilized plant extracts, chitosan, alginate, and cellulose-based materials as reducing agents and stabilizers during bimetal synthesis. Research works on the synthesis of Fe-based and Al-based bimetals initially declined but increased in 2018, followed by a stable trend, with 50% of the total studies conducted in the last five years. China led in the number of publications (62.3%), followed by Russia, Australia, and India, while Saudi Arabia had the highest number of citations per document (95). RSC Advances was the most active journal, publishing eight papers from 2014 to 2023, while Applied Catalysis B: Environmental had the highest number of citations per document at 203. Among the three synthesis methods, chemical techniques dominated, particularly supported particles, galvanic replacement, and chemical reduction, while biological and physical methods have started gaining interest. Iron–copper (Fe/Cu), iron–aluminum (Fe/Al), and iron–nickel (Fe/Ni) were the most commonly synthesized bimetals in the last 10 years. Finally, this work was funded by DOST-PCIEERD and DOST-ERDT.

Pisco is an emblematic spirit in Peru and Chile, made from fermented grapes, gaining growing scientific interest over the last two decades. This study aimed to map 20 years of research on Pisco through a systematic bibliometric review. A search was conducted in the Scopus database covering the period from 2004 to 2024, applying the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology for the transparent selection of scientific articles. The search strategy considered titles, abstracts, and keywords, using the terms “Pisco” and “schnapps”, excluding unrelated fields such as geology (basin, seismic, fossil). The initial search yielded 360 records. After removing non-original articles (books, book chapters, conference papers, and reviews), 101 articles remained. A further screening excluded irrelevant studies (e.g., those referring to the city of Pisco rather than the beverage), resulting in 78 articles included for final analysis. It was observed that 19% of the studies focus on the history, culture, and appellation of origin; 14% on environmental sustainability; 10% on innovation and quality; and 9% on the bioactive properties of by-products. Other areas include extraction technologies (9%), distillation process modeling (8%), and marketing and economics (8%), among others. Recent trends are related to clean production practices. Thus, Pisco by-products and their components can be exploited by applying technologies such as supercritical fluids, drying, and biofilms, while, for waste management, the processes of composting, solar photo-Fenton, and ozonation can be applied. Moreover, it is important to highlight that the valorization of Pisco by-products opens opportunities for translation into the market, particularly in developing cosmetics, nutritional supplements, and bio-packaging materials, contributing to sustainability and innovation in new industries. However, a more holistic view is still needed in Pisco research. These findings suggest that future research should prioritize the integration of consumer-based sensory evaluations and sustainable production innovations to optimize Pisco’s quality, enhance market acceptance, and promote environmentally responsible industry practices.

Several EU initiatives and directives emphasize waste reduction and immediate reuse at the source. This study introduces a novel on-site recycling method for transforming printing house paper waste into high-quality, eco-friendly cardboard without mixing it with lower-quality or heterogeneous waste streams. Instead of traditional water- and energy-intensive recycling processes, the proposed dry defibration method involves mechanical grinding, spray-on binder application, and heat pressing, significantly reducing the ecological footprint. The process was optimized using environmentally safe binders, such as poly(vinyl alcohol), sodium alginate, sorbitol, cellulose nanofibrils, and water, applied at low concentrations. A binder-to-dry-pulp ratio of 160 wt.% offered the best balance, yielding cardboard properties comparable or superior to those obtained by traditional methods. Focusing on book covers, the method demonstrated a 50% reduction in GHG emissions compared to conventional paper recycling and purchased cardboard use. The findings highlight the potential of localized, resource-efficient recycling processes to support sustainable production practices within the printing industry. Full article

Geometry problem understanding (GPU) is a fundamental task in machine intelligence for problem-solving, requiring more accurate and complete information extraction than general natural language understanding tasks. This paper proposes a knowledge and semantic fusion method to achieve high-quality, interpretable, and scalable GPU. It extracts text-level and knowledge-level entities and relationships from problem texts and transforms them into a semantic knowledge graph. First, a dual-layer semantic-enhanced knowledge ontology model (SGKO) tailored for the geometry domain is constructed. By separating the ontology and data layers and combining the strengths of both the knowledge system type ontology and the semantic network type ontology, it enables bidirectional association between conceptual-level knowledge and object-level textual data. Second, a dynamically generated modular relationship matching template is introduced, which is decomposed into reusable atomic components and dynamically assembled through knowledge base queries, significantly reducing template quantity while enhancing adaptability to complex text structures. Additionally, a state-machine-based semantic information extraction model (IDIM-T) is designed that achieves efficient and interpretable semantic extraction through categorized relationship description types. This is combined with a rule-based method (IDIM-K) to complete knowledge-level entity relationship extraction. To validate the method, a dataset was constructed from authoritative sources, including past middle school exam questions, textbooks, and exercise books, covering unary, binary, and ternary relationships, as well as single-clause, cross-clause, and multi-relationship conjunction expressions. Experiments on 230 problems with complex relational descriptions showed that the proposed method achieved fully accurate two-level relationship parsing for 91.87% of the problems. Compared with four baseline methods (sentence template-based, Bi-LSTM-based, Transformer-based, and $S^2$-based), the method achieved the highest F1 score (0.974) for 1832 relationships, outperforming the highest F1 score (0.900) of the baselines.

The rapid development of machine learning and artificial intelligence approaches is finding ever wider application in various areas of life. This paper considers the problem of improving editorial and publishing processes, namely self-publishing, when designing book covers using machine learning and generative artificial intelligence (GAI) methods. When choosing a book, readers often have certain expectations regarding the design of the publication, including the color of the cover. These expectations can be called color preferences, and they can depend on the genre of the book, its target audience, and even personal associations. Cultural context can also influence color choice, as certain colors can symbolize different emotions or moods in different cultures. Cluster analysis of book cover images of the same genre allows us to identify color preferences inherent in the genre, which is proposed to be used when designing new covers. The capabilities of generative services for creating and improving cover designs are also investigated. An improved flow chart for using GAI in creating book covers in the process of self-publishing is proposed, which includes new stages, namely exploring, conditioning, and evolving. At these stages, the designer creates prompts for GAI and examines how they and GAI’s issuances correspond to the task. Conditioning allows for even more precise adjustment of prompts to features of each book, and the evolving stage also includes post-processing of results already received from GAI. Post-processing, in turn, can be performed both in generative services and by a designer. The experiment allowed us to use the machine-learning method to determine which colors are most often found in book cover layouts of one of the genres and to check whether these colors correspond to harmonious color palettes. In accordance with the proposed scheme of the design process using generative artificial intelligence, versions of book cover layouts of a given genre were obtained. Full article

In 1806, Charles Fothergill, a young man with a strong interest in natural history, set out on a seven-month tour of Orkney and Shetland. His goal was to write a book about the islands that would emulate the work produced by the earlier traveller Thomas Pennant on Wales and mainland Scotland. Despite his ambition, Fothergill never succeeded in completing his book. His surviving manuscripts, which range from a rough working journal covering one part of his journey to some comments on botany that seem ready to go to press, suggest some of the difficulties that he might have found both in constructing a coherent narrative of his travels and in recreating a version of Pennant’s antiquarian and scientific travels at a time when tastes in travel writing were shifting to focus more on the pleasures of landscape and aesthetics.

This study examines cyber sextortion research using a comprehensive bibliometric analysis. In the field of cybersecurity, cyber sextortion is a form of cybercrime that leverages privacy violations to exploit a victim. This study reviewed research developments on cyber sextortion progressively over time by looking at scientific productions, thematic developments, scholars’ contributions, and the future thematic trajectory. A bibliometric approach to analyzing the data was applied, which covered 548 peer-reviewed articles, conference papers, and book chapters retrieved from the Scopus database. Results showed a growth trajectory on various thematic concerns in the cyber sextortion field, which has continued to gain traction since the year 2023. Notably, online child sexual abuse is a growing theme in cyber sextortion research. In addition, among other themes, adolescents, mental health, and dating violence are receiving interest among scholars in this field. Additionally, institutions and prolific scholars from countries such as the United States of America, Australia, and the United Kingdom have established research collaborations to improve understanding in this field. The results also showed that research is observed to be emerging from South Africa and Ghana in the African region. Overall, there is potential for more scientific publications and researchers from Africa to contribute to this growing field. The value this study holds is moving beyond deficit-based approaches to how adolescent youth can be resilient and protected from cyber sextortion. A call for a multidisciplinary approach that moves beyond deficit-based approaches toward resilient and autonomy-based approaches is encouraged so that adolescent youth are protected from exploitation. This approach should focus on investigating proactive and resilience-based interventions informed by individuals’ traits and contexts to aid in building digital resilience in adolescents.

Background: Preconception health is critical for improving maternal and child health. The main objective of the study was to explore medical students’ health habits, quality of life, and knowledge of preconception healthcare. Methods: We conducted a cross-sectional study between 15 March 2023 and 31 May 2024 among medical students at United Arab Emirates University. To determine awareness and knowledge of preconception health, we administered a survey consisting of an author’s questionnaire with 35 questions covering sociodemographic characteristics and general knowledge of preconception health, as well as the WHO Quality of Life Scale-BREF (WHOQOL-BREF). Results: The participants were predominantly under 25 years old (98.5%), Emirati (91.1%), single (92.6%), and female (95.8%); only 3.4% had been pregnant before. Regarding health awareness and behaviors, a significant number of females (58.0%) had never visited a gynecologist. The majority of students (72.4%) participated in sports activities. The overall level of knowledge was low, with a mean level of 7.5 (SD = 6.36) out of 24. The Internet (webpages, blogs, webinars) (64.5%) was the major source of knowledge regarding healthcare information, followed by social media platforms (Twitter, Facebook, TikTok, Instagram) and mobile applications (57.5%), books (48.6%), and family members (57.0%). There was a statistically significant correlation between knowledge levels and the Internet (p < 0.004) or family (p < 0.001) as a source of knowledge. Additionally, there was a statistically significant positive correlation between knowledge and quality of life across all four WHOQOL domains. Conclusions: Medical knowledge might positively affect general well-being. Fostering stronger social networks and support systems could benefit preconceptional awareness and knowledge. Full article

Background: Dysmenorrhea affects many women of reproductive age. Physical exercise has been used as an effective intervention for pain reduction and to improve well-being. Physiotherapy, involving movement and exercise, can be effective in relieving menstrual pain and provide additional benefits. The aim is to identify therapeutic physical exercise program and exercise protocols used to reduce pain among these women. Methods: A scoping review was conducted in accordance with Joanna Briggs Institute’s methodology, using the PCC acronym. Articles were sourced from: PubMed, Cochrane Library, PEDro and ScienceDirect, covering studies published between 1 January 2013 and 30 April 2023, representing the period we considered most appropriate at the time the study was initiated. Qualitative studies, books, book chapters, systematic reviews, meta-analyses and review articles were excluded. Studies were analyzed according to the PRISMA-ScR framework. Results: 3325 studies were identified, but only 9 were included. Considerable variation was observed in the types and parameters of the exercise program across studies, including differences in duration, intensity, number of repetitions and series. Conclusions: The findings of this study highlight that aerobic training, particularly among women in their 20s, emerged as the most frequently utilized form of therapeutic physical exercise for alleviating menstrual pain in the studies reviewed. This suggests that aerobic exercise may hold significant promise as a non-pharmacological intervention for managing dysmenorrhea. Full article

Mandaeism is the only ancient Gnostic religion surviving to the present day from antiquity. ‘Gnosticism’ was a block of creative religious activity mostly responding to the early Christian teachings in unusual ways of cosmicizing Jesus, and presenting a challenge to the ancient church fathers in the first-to-third centuries CE. Mandaeism, by comparison, has roots from John the Baptist rather than Jesus, although it is also important to recognize that this baptizing movement emerged in part as a survival of a very old indigenous ethno-religious grouping from Mesopotamia, its followers eventually settling in Mesopotamia’s middle and southern regions. Indeed, much of the Mandaeans’ thought and practice, especially their rituals of water ablution, have deep origins going back to Sumer, Akkad and Babylonia, reflecting regionally wide influences from right across the Fertile Crescent. Mandaean culture and the Mandaic Aramaic language was of high report in the so-called Patristic period covered by this Special Issue, even in the Arabian Peninsula up until the rise of Islam (634 CE onward), and Mandaeans were honored as a third “People of the Book”—the Sabians (Ṣābeʾun; or ṣobba in modern Iraqi Arabic)—in the Qur’an (2:62; 5:69; 22:17); in the Muslim world, many Mandaic speakers switched language to colloquial Iraqi Arabic and (Arabicized) Persian. This article aims to raise some basic questions, relevant to Patristics, about aspects of relationships between Mandaeans and both early ‘mainstream’ Christians and the other large grouping, the Manichaeans. These questions first concern the common flight of the followers of John and Jesus just before the Roman siege and destruction of Jerusalem (66–70 CE) and the role of the woman Miriai; second, the extent to which John and his followers affected the direction of early Christianity, and the consequences this had for ‘Baptist’/Christian relationships into the Patristic period, with attention paid to Mandaean views of Jesus; third, the process of the formation of early Mandaeism as it combined Hellenistic-Palestinian and Mesopotamian elements; and fourth, the signs that the Mandaeans not only influenced Mesopotamian Christian baptismal sects but were crucial in the emergence Manichaeism (from the 230s CE in Persian-dominated Iraq). This article will finish by concentrating on Mandaean–Manichaean relations in the light of a little known and previously secret Mandaic text (Diwan Razia), best known as Mani or Sidra d-Mani within a larger collection of unnamed occult texts. On the basis of the Mandaeans’ texts, we maintain that both Jesus and Mani apparently left their fold in turn. Full article

Home-cooked meals are linked to healthier diets, but assessing cooking skills accurately remains challenging. This review aimed to evaluate and compare available validated instruments to assess adult cooking skills; the Joanna Briggs Institute’s manual and PRISMA-ScR checklist were followed. A search was conducted in April 2024 in five databases using MeSH Terms and adaptations, including studies written without time or language restrictions and with validated instruments to assess adult cooking skills. Reviews, conference abstracts, books, chapters, and case reports were excluded; 1070 studies were identified, and 38 remained after removing duplicates and applying eligibility criteria. Eleven different instruments were identified. Some instruments have been successfully adapted and validated in various countries, covering a broad range of skills, such as meal organization, preparation and cooking techniques, providing a thorough assessment of cooking skills. The Cooking and Food Skill Confidence Questionnaire was considered the best available model, considering its items and domains, direct relation to cooking skills, and easy translation into other cultures. The analysis revealed significant variations in the scales used, with some instruments offering detailed assessments of specific cooking techniques and easy cultural adaptation while others focused more on confidence and attitudes.
