Photocatalysis and Phosphorus Drive Organic Production in Algal-Bacterial Co-Cultures Treating Oil Sands Process Affected Water
Authors: Chidiac Cassandra , Leshuk Timothy , Gu Frank
Published: December 2024

Photocatalysis has been previously identified as an effective pre-treatment for biodegrading naphthenic acid fraction compounds (NAFCs) in oil sands process-affected water (OSPW), achieving mineralization rates unattainable by standalone methods. However, previous studies focused on bacteria cultures for biological treatment, overlooking the potential of algae-bacteria co-growth and its possible effects on enhancing mineralization. Thus, this study replicated those experiments under conditions that promote algal growth. Synthetic OSPW underwent photocatalytic pre-treatment for varying durations, followed by biological treatment in illuminated microcosms. Biostimulation, through phosphate addition, was also tested to determine its effect on accelerating mineralization. Photocatalytic pre-treatments of 24 hours or longer created oligotrophic conditions, triggering the production of algal-derived organics, which released nutrients into the water and reduced mineralization rates during the biological treatment phase. Moreover, nutrient addition generally exacerbated these effects by promoting photosynthetic biomass growth. Nutrient-fixing and symbiotic microbes were identified, contributing to prolonged organic production phases. These phases of persistent organic generation could pose a risk of eutrophication, highlighting the need to mitigate light exposure during post-biological treatments. Under controlled light exposure, BPCs with biological treatments offer a scalable, energy-efficient solution for addressing complex industrial wastewater challenges, advancing the sustainable management of OSPW and similar hard-to-treat water sources.

Published: December 2024

Promethium is the only Lanthanide (Ln) that exists exclusively as unstable isotopes, which consequently prevents its occurrence in appreciable amounts in nature. Lns have shown to be biologically relevant for methanotrophic and methylotrophic bacteria. This paper presents growth studies on the methanotrophic bacterium Methylacidiphilum fumariolicum SolV with Pm-147 along with enzymatic assays of its Ln-dependent methanol dehydrogenase. The results indicate that Pm is positioned precisely as assumed within the Ln series in a biological context, despite its radioactivity.
Alloyed Molybdenum Enables Efficient Alcohol Hydrodeoxygenation with Supported Bimetallic Catalysts

Published: December 2024

Bimetallic heterogeneous catalysts combining group 9 metals (Rh, Ir) or group 10 metals (Ni, Pd, Pt) with Mo on a silica-based support have been synthesized via surface organometallic chemistry and assessed in their catalytic activity for the hydrodeoxygenation (HDO) of alcohols with particular emphasis on the structural evolution of the catalysts and the role of Mo. The investigation was conducted with an air-free approach to isolate any sample alterations exclusively to those caused by the reaction. Structural analysis was performed using a combination of (S)TEM, IR, and XAS. It was found that Ir-Mo/SiO2, Rh-Mo/SiO2, and Pt-Mo/SiO2 display high activity for primary, secondary, and tertiary alcohol deoxygenation, while Pd-Mo/SiO2 only effectively catalyses tertiary alcohol deoxygenation. All other combinations as well as the corresponding monometallic materials do not display the same activity. Using X-ray absorption spectroscopy, the chemical states of M (M = Ni, Rh, Pd, Ir, or Pt) and Mo in the catalysts could be elucidated both before and after the HDO reaction, revealing M to be in metallic state. Mo K-edge X-ray absorption near-edge structure (XANES) spectra showed variations in the amount of Mo(0), Mo(IV) and Mo(VI) depending on the metal counterpart in the fresh catalysts, while complete conversion of Mo(VI) to lower oxidation states was demonstrated in the spent catalysts. For Rh, Pd, Ir, and Pt alloyed nanoparticle formation (M-Mo) was identified by the presence of M-Mo paths, confirmed via combined extended X-ray absorption fine structure (EXAFS) fits of the Mo K-edge and the corresponding M K- or L3-edge. Alloying is further supported by changes in the electronic structure of the nanoparticles supported on SiO2, as revealed by changes in CO-adsorbed IR spectroscopy. On the other hand, Ni-Mo/SiO2 did not exhibit an alloyed structure that was stable under reaction conditions, paralleling the ob-served inactivity for HDO. These findings provide new insights into the structure-activity relationship of Mo-based bimetal-lic catalysts, highlighting the critical role of metal alloying and oxidation state changes in selective alcohol deoxygenation, where reduced Mo species are key to efficiently activate C–O bonds.
Screening of Lanthanum-Based Perovskites for the Oxygen Evolution Reaction at Industrial Conditions for Alkaline Water Electrolysis

Published: December 2024

Perovskites are broadly considered a promising class of catalysts for the oxygen evolution reaction (OER) in alkaline media. In particular, lanthanum-based perovskites, like La0.75Sr0.25MnO3-δ (LSMO), LaFeO3-δ (LFO), La0.6Sr0.4Fe0.98O3-δ (LSFO), La0.6Sr0.4Fe0.8Co0.2O3-δ (LSCFO) and La0.6Sr0.4Co0.99O3-δ (LSCO), have been researched as catalysts for the OER showing high catalytic activity. Stability assessment, on the other hand, is rarely carried out at industrial operating conditions, despite it being a precondition for industrial uptake. In this study, the material stability and intrinsic activity were evaluated at industrial alkaline water electrolysis conditions. LSMO showed high activity but instability due to Mn leaching. LSCFO and LFO demonstrated high activity at 75°C, but computational Pourbaix diagrams of both LFO and LSCFO predict instability at the operational potential window, which was confirmed during long-term stability testing. The overall findings highlight the importance of long-term testing at industrial operating conditions, as stability investigations at mild laboratory conditions are insufficient to qualify a candidate catalyst for industrial uptake.

Published: December 2024

A recycling by design challenge for methacrylate-rich polymers, with applications such as coatings, casts, protective materials and pharmaceutical formulations, is the precise systematic incorporation of (bio)degradable thioester bonds to achieve intrinsic (bio)degradability upon environmental disposal. Unfortunately the most efficient (degradable) thionolactone dibenzo[c,e]oxepine-5(7h)-thione (DOT) is incompatible with methacrylate derivatives, implying the absence of MMA-DOT-MMA formation in poly(methyl methacrylate (PMMA) backbones. As shown in the present work, DOT can be encapsulated through a fast radical ring-opening polymerization (rROP) in a symmetric triad, by utilizing methyl acrylate (MA) or N-phenyl maleimide (PhMal) as an auxiliary comonomer. The intriguing formation of MA-DOT-MA and PhMal-DOT-PhMal triads is realized, and demonstrated to be compatible with MMA addition. This enables the controlled formation of MMAx-(MA-DOT-MA)-MMAy and MMAx-(PhMal-DOT-PhMal)-MMAy, hence, for the first time the well-defined inclusion of degradable moieties in PMMA backbones with low DOT amounts. Validated Coupled Matrix-based Monte Carlo (CMMC) simulations are utilized to design the synthesis conditions by playing with the initial comonomer and solvent amounts. Specifically, these simulations identified unconventional synthesis conditions, resulting in a 2 times shift in the peak average molar mass for the MMA/DOT/PhMal degradable polymer (number average molar mass Mn of 60,000 g.mol-1) and a 25 times lower Mn for the degraded oligomers (2,000-2,500 g.mol-1 within the target range). The model-based insights have been experimentally confirmed, opening the pathway to regulated (bio)degradability for polymethacrylates under industrially relevant radical polymerization conditions.
New Multiple Choice Formats: The Omission Item
Authors: Hanspeter Bauer  , Helmut Bonheim
Published: December 2024

The omission item in a multiple choice test consists of a text in which four or five words or phrases are marked, only one of which is essential to the grammatical, syntactic or logical coherence of the text. Such items have a number of advantages: they allow authentic language materials to be used; a wide range of facility indices can be achieved, including those required for advanced and sophisticated learners of English as a foreign language as well as native speakers; the discrimination indices are unusually high, which suggests that the item taps layers of ability in understanding difficult texts. The format allows a number of variations: the key can be defined as the string which is essential, but also the string which is disposable (mere verbiage or deadwood). Half a dozen examples of these types is presented, together with the results of a factor analysis based on trials involving up to 500 candidates.
Frequency and Variability in Errors in the Use of English Prepositions
Authors: Rosa María Jiménez Catalán
Published: December 2024

The purpose of this study is: a) to determine the frequency of preposition errors in a descriptive composition written by Spanish secondary students; b) to prove the systematicity of these errors in students from different state secondary schools; c) to carry out a tentative qualitative analysis of the variability of prepositional errors in terms of their formal classification, and in terms of the linguistic contexts in which they occur. Although percentages differ from one school to another, the results show that preposition errors are the most common of all errors. Results also show considerable difference in the frequency of error types: substitution errors are far more common than omission or addition errors. We have also obtained evidence that preposition errors seldom appear in linguistic contexts such as preceding non-finite -ing clauses and stranded-preposition constructions including wh-questions and zero-relative clauses.
El proceso de captación racional y su expresión léxica en inglés y español
Authors: Fernández de Bobadilla Lara Natividad
Published: December 2024

El objetivo de este trabajo es delimitar y estructurar la dimensión léxica que engloba el proceso mental de «captación racional» (dentro del campo semántico de la «cognición»). Para ello, se realiza un análisis contrastivo de los lexemas verbales del inglés (Ll) y del español (L2) que pertenecen al núcleo de este dominio semántico, tanto a nivel sintagmático como paradigmático, incluyendo información semántica y sintáctica para cada predicado. El estudio se plantea desde una perspectiva funcional-lexemática (L. Martin Mingorance), que integra dos modelos descriptivos: La Lexemática Estructural (E. Coseriu y H. Geckeler) y la Gramática Funcional (S. C. Dik). Este tipo de análisis implica dos etapas -intralingual e interlingual- con el fin de señalar las principales diferencias y similitudes entre los predicados de ambos niveles.
The Hunchback and the Mirror: Auden, Shakespeare and the Politics of Narcissus
Authors: Smith Stan
Published: December 2024

In various essays from the 1950s collected in The Dyer's Hand (1963) as "The Well of Narcissus" and "The Shakespearian City," W. H. Auden attempts to establish a connection  etween the timeless world of primary narcissism and the order of politics. He argues in "Hic et Ille" that the political demagogue succeeds by converting the frustrations and anxieties of individual narcissism into a political project which creates a "public minor" where the collectivity can find an identity and outlet for its self-regard.
Shakespeare's History Plays, he argues in "The Prince's Dog," depict a world in which the primary realm of wish represented by Falstaff, an infantilised Lord of Misrule and improbable Narcissus, confronts the historical consciousness concerned with governance and political order, the institution of monarchy embodied in the "Prince of this World," Prince Hal.
This antithesis can be used to elucidate a series of famous poems written in the 1930s in which Auden attempts to understand the popularity and appeal of totalitarian politics to an exploited underclass. Auden, following the model adumbrated by Reich, Fromm and other "Left" Preudians, sees fascism, in its capacity to appeal to the infantile wish-fulfilment fantasies of the average "sensual man-in-the-street," as articulating the unconscious of the masses in the interests of its own corporatist fantasies, which ultimately lead to world war. The poems considered here include, from Look Stranger! (1936), "The earth turns over," "Now the leaves are falling fast," "Easily, my dear, you move" (later called "A Bride in the 30s"), "Epilogue" and, from Another Time (1940), "In Memory of Ernest Toller" and "September 1, 1939." In the latter, "Imperialism's Face" is briefly perceived as our own, making us accomplices of its misrepresentations and atrocities. Auden's idea of how ideology conscripts the unconscious has many points of convergence with that of Louis Althusser. Another Time, on the verge of global war, tries to envisage a Freudian therapy that redeems primary narcissism from its fascist usages. It remains a desperate dream, in this watershed volume.
'They Lived Happily Ever After': Ending Contemporary Romantic Comedy
Authors: Celestino Deleyto Alcalá
Published: December 2024

The ideology of romantic comedies has often been located in their attitude to the traditional happy ending: an unproblematic happy ending makes for a film that supports dominant discourses; a problematised one suggests attempts to transgress narrative and cultural conventions. In this essay, I attempt to escape from this inflexible binary logic and propose an analysis of the endings of contemporary romantic comedy which explores the texts' incorporation of cultural transformations and, more specifically, how the strategies of containment and closure negotiate new attitudes in the realm of romantic and sexual relationships in contemporary US American society. As part of a broader research on contemporary developments in romantic comedy, I sketch here five aspects of romantic relationships in which the endings of recent examples of the genre show awareness of social developments: the lonely romantic hero/-ine, the uneasiness about the durability of the couple, the nostalgia for a more innocent past, the impact of changing gender roles both socially and sexually, and the visibility of different gender permutations in intimate relationships.
Quarreling with the Outside Weathers: Dylan Thomas and Surrealism
Authors: Wigginton Chris
Published: December 2024

This essay challenges the traditional readings of Dylan Thomas. Rather than figuring Thomas as a regional romantic, a bardic other to modernism and the Audenesque, it focuses upon the modernist and particularly surrealist elements in his work. It considers in detail a number of poems that deal with the limitations of representation and language in order to suggest that Thomas may be read in a more complex way than has hitherto been the case. It asks that surrealism be recognized as a politicized aesthetic response to crises of the period, and calls for a rethinking of the work of Dylan Thomas in the light of those newer theoretical responses that have emerged since his death.
The Position of Subject Clauses in the History of English
Authors: Javier Rivas
Published: December 2024

In English, subject clauses can occur either preverbally (in-subject initial position) or postverbally (in final position). In order to account for these structures, linguistic theory has presented two major hypotheses: extraposition and intraposition. All through the history of English, the criterion of frequency seems to support the hypothesis of intraposition, since preverbal subject clauses are not found in OE and are a very marginal type in both the ME and eModE periods. The aim of this paper is to account for the factors which favour the occurrence of preverbal subject clauses by examining the evidence attested in the earlier periods of the English language as well as presenting new data concerning the 18th century. The general tendency is for clauses of this type to convey low informational load, sometimes even acting as cohesive links between paragraphs. Other conditioning factors are the text-type and the principle of end-weight.
¿Qué se entiende por "esquema" en la semántica de esquemas?
Authors: Ana María Rojo López
Published: December 2024

En ámbitos como la inteligencia artificial, la psicología cognitiva y la lingüística cognitiva, la creciente adopción de modelos de comprensión basados en estructuras interactivas de conocimiento ha generado una cierta proliferación de etiquetas utilizadas para designar a dichas estructuras (por ejemplo, schemata, schema, frame, script, scenario, etc). De entre todas ellas, las más generales para referirse a estas estructuras de conocimiento parecen ser ‘frame’ y ‘schema’ en inglés, y “esquema” en español. Como resultado, el término frame' ha sido utilizado de manera diferente por un amplio número de autores. Este trabajo intenta aclarar, en la medida de lo posible, la confusión terminológica, definiendo en mayor profundidad la noción d “frame" ('esquema”) y analizando su papel en la teoría sobre el significado conocida con el nombre de ‘Frame Semantics.”

An Education for (Future) Health `Professionals and Literary Scholars: Audre Lorde's The Cancer Journals and Marisa Marchetto's Cancer Vixen
Authors: Cortés Vieco Francisco José
Published: December 2024

Life-writing on breast cancer vindicates women’s health rights, but, as this article demonstrates, the autopathographies Cancer Journals (1980) by Audre Lordeand Cancer Vixen (2006) by Marisa Marchetto also have the potential to teach lessons to (future) health professionals and scholars in literary studies, so that they can, respectively, improve their interactions with patients and understand the therapeutic power of illness narratives to emotionally heal their authors and intended female readers. Lorde uses the weapon of anger both to criticize how cancer patients are dehumanized by the often-insensitive medical profession and to proudly assert her post-mastectomy identity as a one-breasted warrior.Meanwhile, Marchetto opts for humor to describe her eleven-month war against breast cancer and its associated complications: her lack of health insurance to treat her illness and her fear of losing her fiancé. Yet, as this article examines, Cancer Vixen shows the illuminating power of graphic medicine as a breakthrough narrative form, to mitigate the antagonism between doctors and cancer patients, while enhancing literary scholars’ and health professionals’ empathic understanding of patients’ personal stories of illness beyond clinical and hospitalencounters.
Spaces of S(h)elf-Care: Therapeutic Narrative Readings in Anorexia
Authors: Riestra-Camacho Rocío
Published: December 2024

This paper delves into the realm of art therapy, offering tentative evidence of the effectiveness of reading in anorexia nervosa (AN) recovery based on an analysis rooted in three theoretical frameworks: cognitive literary criticism, space studies and the perspective of care. In the first part, AN is discussed as a spatial disorder and one which compromises practices of care. The second partof the paper explores narrative transportation theory, a cognitive literary studies paradigm that explores the various psychological effects of reading, and on mental imagery, a concept that focuses on the mental effects of descriptions and imagery in books. By drawing on research from these spheres, this theoretical framework serves as a valuable lens to frame the third part of the paper, which addresses the pivotal role played by reading in Laura Freeman’s journey toward overcoming anorexia, as depicted in her autobiographical work The Reading Cure: How Books Restored my Appetite (2018). In particular, thestudy offers a close reading of some of the narratives Freeman addresses in her work, meaning the fiction and non-fiction texts she found inspiring, which exclude poetry and drama, and which stimulated her appetite through vivid descriptions of food.
Verbal and Non-verbal Realizations of Persuasive Strategies in Video Resumes
Authors: Mestre-Segarra María Ángeles
Published: December 2024

With the rapid shift from print to digital modes of communication, new genres have emerged. One example is the video resume (VR). This novel professional digital genre enables job seekers to enhance their visibility and connect with broader audiences through various semiotic modes. The VR has a clear communicative aim based on a strong persuasive component: to secure a job by convincing the audience of their qualities. The premise of this paper is that VRs are not only informative but also inherently persuasive. Accordingly, the study aim is to explore the use of multimodal semiotic modes as a way of realizing persuasive strategies (i.e. attention-getting, anticipation and control of responses, rapport, emphasis and processing aids). The methodological approach uses video-based analysis and computer-aided multimodal discourse analysis (MDA) to analyze a dataset of 8 VRs from the online platform YouTube, considering the following criteria: limited duration, impact, year uploaded and editing. The results suggest that verbal and non-verbal realizations of persuasive strategies are present in the fragments analyzed, and such strategies are encoded by heterogeneous combinations of semiotic modes. Although the strategies and modes are not always consistent, they contribute to achieving the communicative purpose of the genre. As for pedagogical implications, this genre and its features can be incorporated into English for Specific Purposes (ESP) teaching materials, enhancing learners’ persuasive strategies and developing their multimodal communicative competence.

In the dynamic outlook of current educational management, pedagogical leadership, interpersonal relationships and organisational climate emerge as fundamental pillars for institutional success. This research explores the intricate interconnection between these three crucial elements in the context of public elementary schools in the Aymara region of Perú. The methodology used corresponds to the quantitative approach and a descriptive-correlational design. The study analysed the perceptions of 125 teachers from six primary educational institutions by applying validated questionnaires. The findings reveal significant correlations between the variables; a high positive relationship between pedagogical leadership and interpersonal relationships (r=0.99), between pedagogical leadership and organisational climate (r=0.99), and between interpersonal relationships and organisational climate (r=0.96). It is concluded that there is a high degree of positive relationships between the three variables. These results validate the hypotheses put forward and underscore the critical importance of leadership in creating a harmonious and productive educational environment. The implications of this study are profound, highlighting how effective leadership can catalyse positive interpersonal relationships and, consequently, foster a healthy organisational climate, resulting in a cordial atmosphere for the educational community. Based on social and emotional skills, this synergy emerges as the key to achieving institutional goals in today's challenging educational environment. The analysis provided offers a solid foundation for future research and implementing more effective and holistic educational management strategies.

Published: December 2024

El carcinoma de células de Merkel ha sido objeto de una investigación científica activa en los últimos años y ha surgido nueva información sobre el tema. Aunque es poco frecuente, este carcinoma neuroendocrino cutáneo primario, que suele afectar a la cabeza y el cuello de las personas mayores, tiene un mal pronóstico. En las últimas dos décadas, un aumento en la incidencia del tumor y el descubrimiento de su relación con el poliomavirus de células de Merkel han centrado la atención médica en la lesión. Los estudios resultantes han mejorado nuestra comprensión de la biología de la neoplasia y han contribuido a la atención clínica. En concreto, han salido a la luz dos subgrupos patogénicos del tumor, la mayoría debido al poliomavirus de células de Merkel y la minoría causada por el daño genético inducido por la radiación ultravioleta. Esta dicotomía conlleva implicaciones pronósticas a favor del primer subconjunto. Además, después de haber aprovechado la conocida susceptibilidad del tumor a las influencias inmunitarias, los investigadores han descubierto recientemente su capacidad de respuesta a la inhibición de los puntos de control inmunitarios. Esta revelación ha constituido un hito terapéutico a nivel clínico. En este artículo ofrecemos una visión general del tema, esbozamos las actualizaciones en el campo y hacemos hincapié en los aspectos dermatopatológicos del carcinoma de células de Merkel.

Introduction: The aim was to determine the cost-effectiveness and cost-utility of additional hyperbaric oxygen therapy (HBOT) compared to standard care (SC) for ischaemic diabetic foot ulcers (DFUs) regarding limb salvage and health status.
Methods: An economic analysis was conducted, comprising cost-effectiveness and cost-utility analyses, with a 12-month time horizon, using data from the DAMO2CLES multicentre randomised clinical trial. Cost-effectiveness was defined as cost per limb saved and cost-utility as cost per quality-adjusted life year (QALY). The difference in cost effectiveness between HBOT+SC and SC alone was determined via an incremental cost-effectiveness ratio (ICER).
Results: One-hundred and twenty patients were included, with 60 allocated to HBOT+SC and 60 to SC. No significant cost difference was found in the intention-to-treat analysis: €3,791 (bias corrected and accelerated [BCA] 95% CI, €3,556 –€-11,138). Cost per limb saved showed an ICER of €37,912 (BCA 95% CI €-112,188–€1,063,561) for HBOT+SC vs. SC. There was no significant difference in mean QALYs: 0.54 for HBOT+SC vs. 0.56 for SC alone (-0.02; BCA 95% CI -0.11–0.08). This resulted in a cost-utility of minus €227,035 (BCA 95% CI €-361,569,550–€-52,588) per QALY. Subgroup analysis for Wagner stages III/IV showed an ICER of €19,005 (BCA 95%CI, €-18,487–€264,334) while HBOT did not show any benefit for Wagner stage II.
Conclusions: HBOT as an adjunct to SC showed no significant differences in costs and effectiveness for patients with DFUs regarding limb salvage and health status. However, for patients with Wagner stage III/IV ischaemic DFUs there was a trend towards better effectiveness and cost-effectiveness.

Introduction: Characterisation of the recreational diving community could help to identify scuba divers at risk for accidents.
Methods: We performed a cross-sectional evaluation in a federation for recreational scuba divers in Belgium (Duiken.Vlaanderen). Using binary logistic regression, factors predictive for accidents leading to hospitalisation were identified.
Results: Of the 710 members, 210 (29.6%) participated in the survey, representing 140,133 dives. Age was > 50 years in 55% and the median (interquartile range [IQR]) number of dives was 380 (IQR 140–935). Cardiac (9.5%), orthopaedic (11.0%), ear-nose-throat (ENT, 10.5%) and allergic diseases (30.5%) were the top four morbidities. Twenty percent reported taking cardiovascular medication. Decompression accidents, barotrauma of the ear and musculoskeletal injuries were reported in 11.0, 11.9 and 11.0%. Fifty-five divers (26.2%) reported incidents not necessitating a medical intervention. For 36 divers (17.1%), medical interventions were necessary. Among these, 13 divers (6.2%) were hospitalised at least once and 12 (5.7%) of these needed hyperbaric oxygen therapy (HBOT). The absolute risk for hospitalisation or HBOT was 0.01% per dive. Age, advanced diving qualification, more dives annually, cardiac or ENT pathology and cardiac medication were significantly associated with an increased likelihood of hospitalisation resulting from diving accidents. In a multivariate risk model, ENT comorbidity (odds ratio [OR] 9.3; P = 0.006) and cardiac medication (OR 5.6; P = 0.05) predicted hospitalisation due to a diving accident.
Conclusions: One in six recreational scuba divers required a medical intervention at least once during their career, while 6.2% were hospitalised or received HBOT. Ear nose and throat comorbidity and cardiac medication were strong predictors for accidents. These should be given sufficient weight in dive medical examination.

Abstract
The present report describes the work performed in the EFSA‐project ‘Data collection, update and further development of biologically‐based models for humans and animal species to support transparency in food and feed safety’. Here, Focus is given to case studies for food and feed chemicals to predict kinetic parameters and profiles using generic and substance‐specific physiologically‐based kinetic (PBK) models for humans, including human subgroups, laboratory animal species, farm animals and a kinetic‐dynamic model in salmon. For humans, five case studies were conducted to compare kinetic predictions using the human generic PBK 6‐compartment COSMOS/TKPlatewith i) in vivo data from human clinical or biomonitoring studies, ii) substance‐specific model predictions using molecules relevant to food safety. Another five case studies assessed the impact of physiological variability (including pregnancy, renal excretion, metabolism variability, or ontogeny) and their impact on biomarkers of exposure. Case studies on laboratory and farm animals focused on theophylline, caffeine, cannabinoids, alkaloids and mycotoxins using the generic 11/12 PBK compartment models integrated in EFSA's TKPlate to assess predicted and experimental parameters i.e. plasma concentrations, excretion via milk or eggs. Overall, predictions from the human generic and substance‐specific PBK models for parameters of chronic exposure were similar and robust compared to the available experimental data. For test species and farm animals, model predictions from the generic TKPlate PBK models also performed well and were mostly within 2‐fold compared to available experimental in vivo data. In addition, 3D molecular modelling case studies were also conducted to investigate transport of chemicals (ochratoxin A, perfluoroalkyls) and cytochrome P450 metabolism (ochratoxin A, safrole and other alkenylbenzenes) as a useful tool to generate metabolism information at the molecular level. Conclusions and recommendations for future work are formulated to further develop generic PBK models for parent compounds and metabolites and further guidance to use and parameterise these models in next generation risk assessment.

Abstract
Ontologies define the main concepts and relations of a domain and can play the role of common language between domain experts, software developers and computer systems, allowing for easier and more comprehensive data management. Ontologies can provide a structure and context for data, enabling better analysis and decision‐making. Ontologies can be leveraged for improving various Machine Learning‐based tasks (they can be used for improving the accuracy and consistency of training data, and we can combine ML‐based predictions with ontology‐based reasoning). Ontologies are key components for achieving semantic data integration. In the context of this deliverable, we have surveyed 40 ontologies and 7 other knowledge organization systems related to food safety and we have categorized them according to a set of appropriate criteria. Subsequently we analysed the 18 case studies, that could involve ontologies, and for each one we have described the possible use of ontologies and what would be the benefit. Finally the identified case studies have been evaluated with respect to a set of criteria regarding benefits, cost and maturity.

Shellfish are rich in essential nutrients and are widely accepted globally. The bacterial contamination, antibiotic susceptibility and heavy metal concentrations on some shellfish muscles above the tolerance permissible limit by WHO/FAO require an in-depth study. An investigative study was carried out on tiger shrimp (Penaeus monodon), pink shrimp (Penaeus notialis) and Lagoon crabs (Callinectes amnicola) obtained from Makoko fish market/landing site on their bacterial quality, antibiotic susceptibility patterns and heavy metal accumulation of bacteria isolated were carried out using standard methods. The highest Total bacterial count (2.48±0.02107cfu/g) was observed in Lagoon crab (C. amnicola) while the lowest count (1.20±0.02107cfu/g) was observed in tiger shrimp (P. monodon). However, the highest Total Faecal count (1.42±0.02104cfu/g) was observed in pink shrimp (P. notialis) while the lowest count was observ ed in P. monodon (1.13±0.03104cfu/g). The bacterial isolates were molecularly identified as (Morganella morganii and Proteus vulgaris) isolated from tiger shrimp, Lagoon crabs had (Proteus mirabilis) while pink shrimp showed (Alcaligenes faecalis). The isolates were 100% susceptible to ciprofloxacin, azithromycin and erythromycin and resistant to cefotaxime, cefuroxime, imipenem/clastatin, augmentin and nitrofurantoin. The mean heavy metals concentration was as follows zincironcoppernickelchromiummanganese Cadmium while Lead and cobalt were not detected in the samples. The study has shown a possible unhygienic environment indicative of the bacteria isolated, a possible environmental spread of antibiotic-resistant bacteria and a heavy metal-contaminated water body. There is a serious need for constant monitoring to lessen future health problems for humans in and around the environment.Keywords: antibiotic-resistant; contamination; Makoko
COMPARATIVE STUDY OF RURAL AND URBAN WOMEN IN KASHMIR: PARTNER VIOLENCE AND REPRODUCTIVE HEALTH

Published: December 2024

The frequency and effects of intimate partner violence (IPV) on reproductive health in Kashmir among rural and urban women are investigated in this paper, together with evaluations of their knowledge, awareness, and practices (KAP). Six hundred women from three districts—Anantnag, Srinagar, and Baramulla who suffered with IPV, reproductive health issues, and their KAP was surveyed. The results show that, in rural women as opposed to urban women, where psychological violence is more widespread, IPV prevalence is higher. With rising STIs, reproductive pain, and medical consultations, results suggest that IPV has significant effects on reproductive health. Comparatively to rural women, urban women show better knowledge, awareness, and more proactive behaviours connected to reproductive health. Particularly in remote regions, the results suggest the need for context-specific treatments, including healthcare services that would integrate IPV screening and reproductive health support. Policies aiming at IPV prevention combined with community education initiatives aiming at raising KAP in rural settings could help reduce the health effects of IPV and promote reproductive health equity. The long-term and cumulative consequences of IPV on health must be investigated in future studies, including a conservative test of the literature on such socio-cultural settings.

The famous saying of Fredrick Muller is always fascinating about India, that goes -“If I were to look over the whole world to find out the country most richly endowed with all the wealth, power, and beauty that nature can bestow – in some parts a very paradise on the earth- I should point to India…and if I were ask to myself from what literature we, here in Europe, who have been nurtured almost exclusively on the thoughts of Greeks and Romans, and of one Semitic race, the Jewish, may draw that corrective which is most wanted in order to make our inner life more perfect, more comprehensive, more universal, in fact more truly human, a life not for this life only, but transfigured and eternal life- again I should point to India.”

This study aims to evaluate the distribution of disaster stimulant funds in Palu City. This study used a quantitative approach with descriptive statistics analysis. It is expected that the results of the study can be operationalized or applied at various levels of government, especially in disaster management. The population of this study was all stakeholders in disaster management in Palu City including the Regional Disaster Mitigation Agency, the Social Service, the Public Works Office, the Sub-District Office, the Village Office, and the Acceleration of Regional Development Executive Monitoring Team (TP4D). This study involved a total of 228 respondents. The determination of the sample used a census technique meaning that the entire population was used as samples. The results of this study showed that the distribution of disaster stimulant funds in Palu City was not effective as the fund was only enjoyed by certain groups and had not solved community problems. This means that there are many complaints from the affected community as they have not been registered as a beneficiary of stimulant funds.This research contributes to the development of public policies related to the policy of distributing stimulant funds for victims of natural disasters consisting of earthquakes, tsunamis, and liquefaction, so policy formulation needs to be designed comprehensively so that it becomes a recommendation for the future because policies related to earthquake, tsunami, and liquefaction disasters have not previously occurred anywhere in the world so that the findings of this study become recommendations for the government in handling increasingly complex natural disasters.
Új misztérium – új öröm”. Greccio 1223–2023 (A CÉ1 alapján)
Authors: Varga Kapisztrán

For Saint Francis of Assisi, there were two windows open towards God: the birth of Christ and his passion, making Christmas one of the most important feasts for him, and he demanded it to be celebrated with the greatest possible solemnity. This paper will explore the claim, based on the biographies of Thomas of Celano and other sources, that Saint Francis was the first to erect a nativity scene. The central element of the celebration of Christmas in Greccio (1223) was the representation of the birth of Jesus with eucharistic signs, while Francis used living characters to dramatize the mystery. The relationship between the Eucharist and the manger was given special significance in his celebrations. Greccio’s novelty was the way Francis celebrated the birth of Jesus with the sacramental signs of the Eucharist: the eucharistic manger recreated the Bethlehem scene and gave it a new meaning.
