Published: March 2024

Cowpea [Vigna unguiculata (L.) Walp], is a popular leguminous vegetable crop grown in the wetland fallows of Kerala, India. Web blight caused by Rhizoctonia solani has turned out to be a problem in cowpeas, leading to substantial yield loss. We isolated 22 endophytic bacteria from fodder cowpea var. Aiswarya and 16 from bush cowpea var. Bhagyalakshmi, and evaluated their plant growth promotion ability and potential for web blight pathogen suppression. Initially, the isolates were screened in vitro for their plant growth promotional traits and antagonism against R. solani. The potential isolates were identified as Bacillus subtilis, B. amyloliquefaciens and B. velezensis through 16S rDNA cataloguing. Plant growth-promoting traits like the production of IAA (Indole acetic acid), ammonia, phosphorus, and siderophore by the promising isolates were also investigated. B. amyloliquefaciens CBSE5 recorded the highest IAA (3.54 microgram/mL) and siderophore production. B. velezensis CBRE5 showed the highest ammonia (177.29 micro moles/mL) production and phosphate solubilization. In the in vivo assay, seed biopriming along with foliar application on 20 and 40 days after sowing, of a consortium of B. amyloliquefaciens CBSE5 and B. velezensis CBRE5 recorded maximum values for all growth parameters viz. shoot length, root length, shoot fresh weight, root fresh weight, shoot dry weight, root dry weight, pod yield and number of pods per plant. The present study reports for the first time the use of endophytic Bacillus spp. isolated from cowpeas as plant growth-promoting bacteria, with biocontrol potential against the web blight pathogen R. solani.

Farmers in the western region of Odisha are grappling with issues related to low fruit set, fruit drop, and erratic yield in mango cultivation. Plant growth regulators (PGRs) play a pivotal role in addressing fruit drop at different developmental stages by modulating the nutritional and hormonal status of the plant. This study aims to investigate the impact of specific PGRs on fruit drop, fruit retention, and overall yield of Mango (Mangifera indica L.) cv. Amrapali in the West Central Table Land zone of Odisha. The experimental setup was implemented at the research plot of the College of Horticulture, Chiplima, Sambalpur, following a randomized block design with ten treatments, each replicated three times. The treatments involved various concentrations of three PGRs: NAA, GA3, and 2,4-D, applied during the pea and marble stages of fruit growth. The outcomes indicated that the application of 30 ppm GA3 significantly mitigated fruit drop, with comparable efficacy observed for 30 ppm 2,4-D. GA3 positively influenced fruit retention, particularly Treatment T7 (30 ppm GA3), exhibiting the highest retention percentages at 30, 60, and 90 days post-spraying. Furthermore, GA3 at 30 ppm resulted in the maximum average fruit weight and volume. The highest number of harvested fruits per plant and maximum yield per plant were recorded in Treatment T7. These findings underscore the potential of GA3 in alleviating fruit drop, enhancing fruit retention, and improving overall yield in mango cultivation, specifically for the Amrapali variety in the West Central Table Land Zone of Odisha.

Gran parte de la actividad en el laboratorio clínico debe quedar documentada para facilitar el mantenimiento de la calidad del servicio, lo que deriva en la generación de una gran cantidad de documentación, formularios e informes. Con tal objeto, es necesario especificar el tiempo de retención requerido para cada tipo de documento y muestra. Además de la obligación de conservar los informes del laboratorio clínico como parte de la historia clínica de los pacientes, el laboratorio también está obligado por ley, o según las directrices de las organizaciones profesionales, si las hubiera, a retener un gran volumen de documentación y muestras. En caso contrario, la dirección del laboratorio deberá establecer un calendario de retención, en el que se especifiquen las condiciones y el periodo de conservación, de acuerdo con los requisitos de la norma ISO 15189:2022 sobre retención de documentación y registros de gestión de la calidad.

En el presente proyecto, el Grupo de Trabajo de la EFLM sobre Acreditación y Normas ISO/CEN propone una serie de periodos de retención de documentación y muestras, basada en la metodología de análisis modal de fallos y efectos (AMFE), un método para la reducción de riesgos que ha pasado a formar parte integral de los estándares actuales.

Social Organization, Intersections, and Interactions in Bronze Age Sardinia. Reading Settlement Patterns in the Area of Sarrala with the Contribution of Applied Sciences
Authors: Lai Luca , Crispu Stefano
Published: March 2024

Bronze Age sites in the coastal area of Sarrala, in Eastern Sardinia, have been subjected to survey and excavation over the last half-century. The study area, whose social and economic evolution and changing scales of interactions are traced through settlement patterns and building analysis, is interpreted in light of more general trends suggested by stable isotopes, archaeogenetics, and paleoclimatology. The local picture of progressive demographic growth and infilling of the landscape, with a subsequent concentration of population and labor, follows a sequence widely detected in Sardinia. More specific identifiable aspects include a comparatively higher fragmentation/competition (ratio of complex vs simple nuraghes; ratio of tombs vs nuraghes) and a consistent pattern in the distribution of non-local building materials in the latest phase at the sites showing archaic features, taken as a clue of a long-lasting authority at select sites. These elements are compatible with organized pastoral exploitation of the available territory, structured according to patrilocality and closeness to ancestral lineages and residences. The interplay of internal dynamics relative to constraints and opportunities is discussed, such as climate change and long-distance trade connections, with possible implications for interpreting Nuragic society.
Association between self-reported pain severity and characteristics of United States adults (age ≥50 years) who used opioids
Authors: Axon David R. , Aliu Oiza
Published: March 2024

Objective:

The aim of this study was to assess the associations between the characteristics of United States (US) adults (≥50 years) who used opioids and self-reported pain severity using a nationally representative dataset.

Methods:

This retrospective cross-sectional database study used 2019 Medical Expenditure Panel Survey data to identify US adults aged ≥50 years with self-reported pain within the past 4 weeks and ≥1 opioid prescription within the calendar year (n = 1,077). Weighted multivariable logistic regression analysis modeled associations between various characteristics and self-reported pain severity (quite a bit/extreme vs less/moderate pain).

Results:

The adjusted logistic regression model indicated that greater odds of reporting quite a bit/extreme pain was associated with the following: age 50–64 vs ≥65 (adjusted odds ratio [AOR] = 1.76; 95% confidence interval [CI] = 1.22–2.54), non-Hispanic vs Hispanic (AOR = 2.0; CI = 1.18–3.39), unemployed vs employed (AOR = 2.01; CI = 1.33–3.05), no health insurance vs private insurance (AOR = 6.80; CI = 1.43–32.26), fair/poor vs excellent/very good/good health (AOR = 3.10; CI = 2.19–4.39), fair/poor vs excellent/very good/good mental health (AOR = 2.16; CI = 1.39–3.38), non-smoker vs smoker (AOR = 1.80; CI = 1.19–2.71), and instrumental activity of daily living, yes vs no (AOR = 2.27; CI = 1.30–3.96).

Conclusion:

Understanding the several characteristics associated with pain severity in US adults ≥50 years who used an opioid may help transform healthcare approaches to prevention, education, and management of pain severity in later life.
Could generative artificial intelligence replace fieldwork in pain research?
Authors: Bojic Suzana , Radovanovic Nemanja , Radovic Milica , Stamenkovic Dusica
Published: March 2024

Background

Generative artificial intelligence (AI) models offer potential assistance in pain research data acquisition, yet concerns persist regarding data accuracy and reliability. In a comparative study, we evaluated open generative AI models’ capacity to acquire data on acute pain in rock climbers comparable to field research.

Methods

Fifty-two rock climbers (33 m/19 f; age 29.0 [24.0–35.75] years) were asked to report pain location and intensity during a single climbing session. Five generative pretrained transformer models were tasked with responses to the same questions.

Results

Climbers identified the back of the forearm (19.2%) and toes (17.3%) as primary pain sites, with reported median pain intensity at 4 [3–5] and median maximum pain intensity at 7 [5–8]. Conversely, AI models yielded divergent findings, indicating fingers, hands, shoulders, legs, and feet as primary pain localizations with average and maximum pain intensity ranging from 3 to 4.4 and 5 to 10, respectively. Only two AI models provided references that were untraceable in PubMed and Google searches.

Conclusion

Our findings reveal that, currently, open generative AI models cannot match the quality of field-collected data on acute pain in rock climbers. Moreover, the models generated nonexistent references, raising concerns about their reliability.

Authors: Karapanagiotis Christos , Schukar Marcus , Krebber Katerina
Published: March 2024

In this paper, we present a comprehensive overview of our research in the field of distributed fiber optic sensors for structural health monitoring of hydrogen composite pressure vessels. Specifically, we demonstrate how the integration of fiber optic sensors into composite pressure vessels enhances safety while simultaneously reducing maintenance costs. The small size of optical fibers enables their integration into composite structures during the manufacturing process, allowing continuous monitoring and precise detection and localization of structural damages during service life. We also discuss the potential of state-of-the-art signal processing methods and machine learning for advancing predictive maintenance. Our applications of fiber optic sensors demonstrate their potential to contribute significantly to the energy transition towards renewable sources.

Amado Alonso (1896-1952) fue un filólogo español – director del Instituto de Filología de la Universidad de Buenos Aires entre 1927 y 1946 – de cuya labor de traducción resultó la primera publicación en español del Curso de lingüística general (Saussure, 1945 [1916]). En el presente trabajo analizamos el modo en que Alonso interpretó la figura de Saussure y algunas ideas fundamentales de su obra póstuma; buscamos hacer particular hincapié sobre sus reflexiones en torno a las nociones de fonética y fonología, dos disciplinas de incipiente desarrollo que guardaban estrechos lazos con los avances científicos de los que fue contemporáneo. Para ello, seleccionamos una serie de contribuciones en las que este filólogo (desde una perspectiva idealista) definió las mencionadas disciplinas, capitalizando los conceptos de valor y de sistema y poniéndolos a formar parte de su interpretación espiritualista del lenguaje. Según observamos, el estudio de la materia fónica era, en el enfoque de Alonso, una herramienta metodológica al servicio de los intereses de la geografía lingüística y la dialectología.

Este artigo visa a explicitar o caminho que Ducrot percorreu para desenvolver um dos projetos fundamentais da linguística de Saussure: o de uma Semântica Linguística. Para tanto, a partir do resgate de noções postuladas pela Argumentação na Língua (ANL), pela Teoria Polifônica da Enunciação (TPE) e pela Teoria dos Blocos Semânticos (TBS), procurase mostrar como a Semântica Argumentativa é, em grande parte, um quadro teórico coerente com os princípios saussurianos, especialmente com os postulados que delineiam uma teoria semântica no capítulo intitulado “O valor linguístico”, do Curso de Linguística Geral. Na primeira seção, elucidam-se princípios e conceitos da ANL e da TBS e efetua-se uma análise semântico-argumentativa de um miniconto. Na segunda, apresenta-se o aparato teórico-metodológico da TPE e sistematiza-se a distinção entre as noções de frase, enunciado, texto e discurso, bem como entre os seus valores semânticos. Por fim, retomamse os princípios saussurianos necessários à pesquisa em Semântica Argumentativa.

Major coastal upwelling systems are among the most productive marine ecosystems in the world. They contribute disproportionately to the cycling of carbon and nutrients in the ocean and influence marine biogeochemistry beyond their productive regions. Characterized by intense microbial respiration (both aerobic and anaerobic), major coastal upwelling systems are also hotspots for the production and outgassing of potent greenhouse gases (GHG) such as CO2, N2O, and CH4. Quantifying and understanding these roles in the context of a changing climate is therefore a subject of great interest. Here we provide a short synthesis of the current knowledge of the contributions of major coastal upwelling systems to the cycling of GHG. Despite variations within and among different systems, low-latitude coastal upwelling systems typically act as a net carbon source to the atmosphere, while those at higher latitudes function as weak sinks or remain neutral regarding atmospheric CO2. These systems also significantly contribute to oceanic N2O and CH4 emissions, although the extent of their contribution to the latter remains poorly constrained. We also overview recent and future changes to upwelling systems in the context of a warmer climate and discuss uncertainties and implications for GHG production. Although rapid coastal warming is anticipated in all major coastal upwelling systems, the future changes in upwelling-favorable winds and their implications within the context of increased stratification are uncertain. Finally, we examine the major challenges that impede our ability to accurately predict how major coastal upwelling systems will respond to future climate change, and present recommendations for future research to better capture ongoing changes and disentangle natural and forced variability.

Twelve-year-old Annette Swinson burst onto New York’s Black music scene in 1953. A darling of the local Black press, Swinson worked as a solo singer throughout her adolescence before replacing Arlene Smith as lead singer of the Chantels. During her career, Swinson’s girlhood evoked connotations of malleability and naïveté that were attractive to music industry men searching for salable sounds. Swinson exploited these assumptions using her extraordinary ability to transform her vocal timbre, but this strategy also complicated the record of her career. This article examines journalistic coverage of Swinson’s career alongside her recorded performances to consider the possibilities afforded by her vocal shapeshifting. Beginning with Swinson’s early period as a child singer, this article argues that Swinson’s legibility as a child highlights the impact of legal minority as a status that denies Black girls’ capacity for rational consent, prevents them from representing their own work, and leaves them vulnerable to abuse. This article also analyzes Swinson’s recorded voice to demonstrate that girls like Swinson used unstable vocal identity as a choreographic technique to work around their legal disempowerment and gain access to professional opportunities. Ultimately, this article suggests that listening to vocal timbre in this way presents a method by which scholars might recognize Black girls’ agency within archival silences and obfuscations.

We present a novel approach to study the three-dimensional network structure of paper. In the KCL-PAKKA simulation model, the porous sheet structure is compiled from the different papermaking raw materials, fibres, fillers and fines. The model geometry is simplified in order to enable effective numerical experiments with arbitrary composition and layering. The KCL-PAKKA model gives realistic predictions for many paper properties . In this paper we describe the cross-over that occurs with increasing grammage from a thin strictly two-dimensional network to a thick layered networks . According to our simulations the cross-over occurs at low grammages, around 20 – 30 g/m2, for papers made of stifffibres (e.g. mechanical pulp) and at higher grammages, 40 – 80 g/m2, for flexible fibres (e.g. beaten kraft). We discuss the statistical properties of the three-dimensional but layered random fibre network, particularly the bonding degree and pore geometry . In thick networks the pore geometry is isomorphic and only the length scale of the pores depends on fibre properties.

Ischemia and reperfusion (I/R) injury permeates a variety of diseases, causing significant inflammatory and thrombotic responses. Given its importance, efforts have been made to identify the complex and integrated network of mediators that ensure a timely and spatially regulated inflammatory response, in order to mitigate its deleterious effects on the body. The Annexin A1 protein (ANXA1) and its mimetic peptide Ac2-26 can alleviate the inflammatory process by decreasing adhesion and neutrophil trafficking, inhibiting pro-inflammatory and pro-thrombotic mediators, and regulating the interactions of neutrophil-platelets. In this review, we discuss the anti-inflammatory potential of ANXA1 and its intracellular effects, contrasting the possible long-term permanence of the damage caused by I/R injuries. As a pharmacological approach, the aim is to understand how ANXA1 operates in processes resulting from I/R injuries and its performance as a biomarker and therapeutic target after injury in different tissues and organs.

Cordura fiber, which has high performance against tearing and abrasion, can be used to improve the tear strength and abrasion resistance of low-weight wool/lycra fabrics that can be suitable for daily wear. Thin wool fabric is very comfortable to wear, but lighter fabrics are more prone to appearance problems, since they are less able to resist the forces responsible for the distortions. This study aims to investigate the effect of cordura fiber integration on the yarn quality properties of wool and wool/Lycra yarn. Cordura fiber was integrated into wool and wool/Lycra yarn structure with different fiber percentages and were tested according to related the standard methods to evaluate yarn quality properties such as breaking force, breaking length (RKM), elongation at break, unevenness (CV%), yarn imperfection (thick, thin places and neps) and hairiness.

Noble hosts: effects of internal parasites on the physiology of an intertidal brooding Sea-star
Authors: Fraysse Cintia Pamela , Boy Claudia Clementina , Veyñ Marianela , Farias Ayelen , Pérez Analía Fernanda
Published: March 2024

Introduction: The endoparasite Dendrogaster argentinensis infects the intertidal brooder sea star Anasterias antarctica. This sea-star species is in the highest trophic level in the Beagle Channel.

Objective: To study the effects of parasitism by D. argentinensis on the fitness and reproduction of A. antarctica.

Methods: Adults from the brooder sea-star were collected from the rocky intertidal of Ensenada Zaratiegui bay (54°51’ S & 68°29’ W), Argentina. Eight seasonal samplings were performed (four seasons in two years) in the upper and low intertidal. During dissection, parasites were removed, and all organs were extracted and weighed separately.

Results: Dendrogaster argentinensis prevalence was the highest for the region (20.4 %). Parasitized individuals were more frequent in the low intertidal in all seasons, with a higher difference in summer, where it is likely that the higher temperatures and strong winds could make the upper intertidal more challenging for a parasitized individual. Five parasitized individuals were castrated. Generally, the gonadal (GI) and somatic (pyloric caeca, PCI; stomach, SI; body wall, WI) indexes were lower in parasitized than non-parasitized individuals.

Conclusions: Parasitism by D. argentinensis negatively affects A. antarctica condition. It affects reproduction because it reduces the GI, and can also produce castration. The parasite competes for the sea-stars’ energetic resources, also decreasing the individual’s capacity for feeding (reduced stomach) and growth (reduced body wall).

Published: March 2024

Introducción: Las especies de las clases Crinoidea y Asteroidea se distribuyen en gran variedad de hábitats en todos los océanos desde la zona intermareal hasta grandes profundidades, existen pocos registros en aguas mexicanas, a profundidades superiores a los 200 m, los escasos registros existentes datan de documentos históricos de la literatura especializada y los ejemplares se resguardan en colecciones científicas extranjeras.

Objetivo: Contribuir a la recopilación de información de los ejemplares resguardados en la Colección Nacional de Equinodermos (CNE) del Instituto de Ciencias del Mar y Limnología (ICML), UNAM y proveer un inventario de las especies de crinoideos y asteroideos que habitan en zonas profundas del talud de la Península de Yucatán, México.

Métodos: Del año 2005 al 2014 se recolectaron ejemplares de crinoideos y asteriodeos en cuatro cruceros en el B/O “Justo Sierra” BIOREPES 1 y 2 y COBERPES 2 y 6. Se realizaron arrastres con red camaronera en 80 estaciones de muestreo.

Resultados: El listado taxonómico comprende 1146 ejemplares, de los cuales 204 son crinoideos del orden Comatulida, distribuidos en tres familias tres géneros y tres especies y 942 asteroideos distribuidos en seis órdenes, 11 familias, 21 géneros y 28 especies. Se obtuvieron los registros nuevos para la CNE: Democrinus rawsonii y Atelecrinus balanoides en crinoideos. Astropecten alligator, Hymenaster modestus, Calyptraster personatus, Pteraster militarioides militarioides, Sclerasterias contorta en asteroideos.

Published: March 2024

Introducción: En el Pacífico central mexicano son escasos los trabajos sobre ecología de asteroideos. Estas especies generalmente se distribuyen de forma aleatoria, aunque en algunas ocasiones pueden encontrarse en grupos o agregaciones. En Los Arcos, al sur de Puerto Vallarta, en Bahía de Banderas, México, se observó Luidia bellonae por primera vez en una agregación masiva en 2021.

Objetivo: Reportar por primera vez el registro de esta especie en esta región del Pacífico mexicano, así como el evento de agregación masiva.

Métodos: Se realizaron transectos y recorridos para cuantificar la densidad y medir los ejemplares de la estrella en Los Arcos, Bahía de Banderas, durante 2021, 2022 y 2023.

Resultados: Se encontraron densidades promedio de 2.65 ind/m2 y hasta 7 ind/m2. En total en el área aproximada de 900 m2 se registraron 630 individuos. Los ejemplares midieron (R) entre 2 y 12 cm, y en su mayoría midieron entre 4 y 8 cm.

Conclusiones: L. bellonae estaba reportada en distintos sitios en algunos estados del Pacífico mexicano, sin embargo no estaba registrada para Bahía de Banderas ni Los Arcos, ni tampoco en la cantidad que se reporta aquí, por lo que este es el primer registro para la especie con una presencia masiva para el Pacífico mexicano. La aparición de la gran cantidad de ejemplares de L. bellonae en Los Arcos en 2021 pudo haber sido resultado de una combinación de factores, entre ellos la baja temperatura del agua, con valores hasta de 15 ºC y la alta cantidad de nutrientes. Este hallazgo demuestra la necesidad de más estudios sobre los equinodermos y especies marinas para entender la influencia que tienen las condiciones ambientales en su ciclo de vida.

Authors: Garcés Marisa , Rubilar Tamara , Cledon Maximiliano , Sequeiros Cynthia
Published: March 2024

Introduction: Sea urchin aquaculture is a rising industry, and in consequence, there is a need to establish optimal culture parameters to ensure the health of the cultured animals.

Objective: To evaluate the bacterial counts in the seawater of sea urchin (Arbacia dufresnii) aquaculture recirculating systems (RAS).

Methods: The bacteriological water quality of two RAS containing sea urchins was determined. For approximately two months, weekly water samples were taken. The bacteriological quality was determined by counting total aerobic heterotrophic populations, lactic acid bacteria, enterobacterias and genus Vibrio. Physicochemical parameters were also measured.

Results: There was no presence of disease or mortality. Enterobacteria and lactic acid bacteria were not detected from both RAS systems. The number of animals had an important effect on the observed difference in the count of total bacteria and Vibrio spp. In RAS 1 the maximum counts of total bacteria and Vibrio spp. were 2.8 x 105 ± 1.7 x 105 and 1.45 x 105 ± 3.6 x 104 UFC ml-1, respectively. In RAS 2 total bacteria and Vibrio spp. exhibited repetitive behavior over time influenced in part by water exchange and mainly by feeding. The results indicate that periodic water changes ensure a limited growth of bacterial strains as Vibrio and other bacteria.

Conclusions: Our results suggests that the bacterial count levels recorded in this study can be used as a threshold or safety limit for Arbacia dufresnii aquaculture.
Preliminary study of the population and reproductive dynamics of Echinaster sepositus (Spinulosida: Echinasteridae) in Cala del Racó
Authors: López Casares Daniel , Hernández Pérez José Carlos , Tena Medialdea José , García March José Rafael
Published: March 2024

Introduction: The red starfish (Echinaster sepositus) is one of the most common asteroid species in the Mediterranean Sea. However, information about their biology or their role in benthic communities is scarce.

Objective: This study aims to provide new information on the ecology of this species through the temporal characterization of the population of E. sepositus in Cala del Racó (Alicante, Spain) and the in situ monitoring of its reproductive cycle.

Methods: For this purpose, three study areas were established at different depths. For each of the recorded starfish, data about the size, the substrate on which it was found, the area, the depth and the sex in the case of observing the reproduction were collected.

Results: A total of 19 samplings have been carried out throughout a year of study. In this way, it has been possible to observe that the density of individuals increases in the shallower zone during autumn and winter, when the temperature drops to 14.13 ºC, while it decreases in spring and summer when the temperature rises to 27.17 ºC. Those results are reversed in the deepest part of the study. The highest density of individuals (0.51 ind/m2) occurred in October. Arborescent photophilic algae and crustose coralline algae were the substrates with the highest number of E. sepositus recorded. Medium to large specimens are located preferably on crustose coralline algae or arborescent photophilic algae, while smaller individuals were mostly located on Posidonia oceanica. No specimens of E. sepositus were observed spawning.

Conclusions: Data leads to assume that there is a migration of starfishes towards more superficial areas when the water is at colder temperature and towards deeper areas when the temperature increases. It is valued the possibility that there is a change in the nutritional needs of E. sepositus throughout its development. According to our observations, the future reproduction studies should be concentrated between late-summer and early-autumn.
Fatty acid composition and metabolic pathways in Arbacia dufresnii (Arbaciidae: Arbacioida) gametes: implications of shrimp byproducts in aquaculture feeds
Authors: Vera Piombo Mercedes , Avaro Marisa , Gittardi Agustín , Cledon Maximiliano , Rubilar Tamara
Published: March 2024

Introduction: Care towards nutrition is essential for the quality of a sustainable aquaculture product. Since the balance in food affects the growth and production of gametes. The circular economy is made possible through the use of discarded materials.

Objective: The aim of this research was to study the fatty acid composition and metabolic pathways in the gametes of Arbacia dufresnii, with a focus on the implications of incorporating shrimp byproducts into aquaculture feeds.

Methods: Four different treatments were designed to maintain optimal nutritional quality, particularly in lipids and proteins, based on previous studies. The fatty acid profiles of the feeds and gametes were analyzed by using gas-chromatography, and statistical analyses were conducted to determine significant differences.

Results: Significant differences were observed in the abundance (%) of omega-3 (ω-3) and omega-6 (ω-6) fatty acids. The (ω-3) metabolic pathway was more pronounced in the gametes of wild animals and those fed with the experimental feeds. In contrast, the (ω-6) metabolic pathway was less relevant in these groups. The (ω-3) /(ω-6) ratio was highest in the gametes of wild animals. Feeds enriched in fatty acids enhanced their bioaccumulation in the gametes reaching higher concentrations than wild animals. The availability of fatty acids in foods allowed their bioaccumulation in gametes, with concentrations equal to or higher than those observed in animals in their natural environment for certain fatty acids.

Conclusions: Incorporating shrimp byproducts in aquaculture feeds demonstrated a promising strategy for resource utilization and organic input generation. The fatty acid composition in the gametes of A. dufresnii was influenced by the diet, highlighting the potential of balanced feeds to enhance the bioaccumulation of essential fatty acids. These findings provide valuable insights for the development of sustainable aquaculture practices and the production of nutritionally enriched seafood products.
Edition of the Saptaguṇavarṇanā parikathā Based on a Newly Identified Sanskrit Manuscript with Special Reference to Its Tangut Translation
Authors: Hu Enbo
Published: March 2024

This paper focuses on a newly identified Sanskrit manuscript of the Saptaguṇavarṇanā parikathā (The Sermon Describing the Seven Qualities), which is currently preserved at the Drepung Monastery in Tibet. It presents the Sanskrit version of the text for the first time, provides a critical edition and translation, and offers a comparative analysis of the Tibetan translation and the Tangut manuscript, known as Инв. № 804. The paper addresses mistakes and omissions in the Sanskrit manuscript, Tibetan and Tangut translations, as well as related misreadings in the scholarship, thus advancing understanding of non-sūtra texts in Tangut Buddhism.

Published: March 2024

Archaeological and historical sources describe differently the course of events that occurred during the Islamic conquest of Jerusalem. Was the transition from the Byzantine to the Islamic period a short and dramatic event or a long and steady process? This study aims to examine the Islamic cultural influences over Jerusalem during the Byzantine/Umayyad period and later post-earthquake of the 8th century CE. Thus, we carried out a study of Mount Zion’s (seasons 2018 and 2019) faunal assemblages, analyzing the species discovered at the site, their demography and distribution between the different architectural contexts. The focus was on evaluating the cultural identity and economic preferences of the local population.
The remains we found indicate that the economy was based mainly on caprines, pigs and fish. As the site was located inside the Jerusalem walls, the locals gained their meat supply from the local markets and might have been involved in agriculture outside the walls. Although the site experienced architectural alterations between the two periods, the Christian population remained, and their faunal economy did not change from the Byzantine period till after the earthquake.
Imported Table Wares in the Palestinian Countryside in the 19th and Early 20th Centuries and Their Integration into (and Influence on?) Local Dining Habits
Authors: Taxel Itamar
Published: March 2024

Archaeological fieldwork in Israel has testified to the presence of a variety of imported glazed table wares of the 19th and first half of the 20th century—notably from the northeast Mediterranean, Europe and the Far East—in numerous locations, including in rural sites of various ranks. The influx of import of these ceramics to the southern Levant and their widespread use reflect the intensifying commercial activity in the eastern Mediterranean and the gradual processes of globalization and quasi-Westernization or modernization among certain local populations. This article examines the extent of use of imported table wares among 19th to early 20th-century Palestinian Arab rural societies, the modes of use of these vessels in food consumption contexts, and consequently the power of foreign (culinary) objects to modify local (dining) traditions. These aspects are investigated by using archaeological materials, historical photographs and some written testimonies. This review shows, on the one hand, that imported table wares were integrated into local kitchens and functioned alongside locally-produced vessels. On the other hand, although many of these imports—specifically the European ones—were originally designated for individual eating, it is shown here that their influence on local, well-rooted traditions of communal dining was minor, especially among the great majority of the countryside population.

Based on low solubility in water and high membrane permeability, resveratrol is collocated in the second class of the Biopharmaceutical Classification System, with limited absorption derived from a low dissolution rate. Solid microdispersion of resveratrol supported by magnesium dihydroxide (Resv@MDH, trademark Revifast®) represents a physical mixture of resveratrol (30% w/w) and magnesium dihydroxide (70% w/w) obtained by traditional techniques, such as mixing and micronization under appropriate conditions. Establishing the wide use of Revifast® in food supplements, in the present work we deepen its physicochemical characterization by using diffractometric and infrared analysis. No novel species are found in the Resv@MDH mixture except magnesium dihydroxide and resveratrol extracted from Polygonum cuspidatum. The results herein reported strengthened the safety of Revifast® ingredients for resveratrol-based food supplements.
A modified hard-templating for hollow mesoporous silica nanoparticles with suitable particle size and shortened synthetic time
Authors: Nguyen Dai Hai , Nguyen Ngoc Hoi , Nguyen Cuu Khoa
Published: March 2024

Hollow mesoporous silica nanoparticles (HMSN), a member of mesoporous silica family synthesized mainly with har-templating method, has gained great interest in pharmaceutical applications due to their impress characteristics such as good biocompatibility, large specific surface area and pore volume, controllable particle size, large cavity for cargo loading, and flexible surface functionalization possibilities. However, controlling the optimal particle size and shortening the synthesis time have been the issues of HMSN synthesis that needed to be improved. In this study, HMSN was synthesized using hard-templating with some modifications to shorten the synthesis time and adjust the particle size to nearly 100 nm. The obtained HMSN particles showed high uniform morphology as spheres with hollow core-mesoporous shell structure, having the particle diameter of about 90 nm, the hollow diameter of about 68 nm, and the mesoporous shell thickness of about 11 nm. The total time for the main reactions was shortened by more than half from 21 hours to 9 hours. Additionally, MTT assays revealed that the synthesized HMSN was biocompatible material. This modified hard-template method with shorter synthesis time and nearly 100 nm obtained particle diameter would be meaningful for scientific research and industrial scale production.
DIVULGAÇÃO CIENTÍFICA EM ESPAÇOS NÃO FORMAIS: UM ESTUDO DE CASO ENVOLVENDO A RELATIVIDADE GERAL E O MUSEU DO ECLIPSE

Published: March 2024

Este trabalho investiga qualitativamente o potencial dos espaços não formais na complementação de uma educação escolar forjada nas instituições formais e nas contribuições prestadas para a divulgação científica, tomando como referência um estudo de caso envolvendo, a Teoria da Relatividade Geral (TRG) e o Museu do Eclipse. O estudo foi concretizado numa pesquisa de campo subsidiado por entrevistas e questionários, nos quais foram envolvidas pessoas que compõem a população sobralense, o primeiro diretor do Museu do Eclipse, o diretor atual e ex-funcionários da instituição. Os resultados apontam para a importância do comprometimento com a cidade, educação e memória; para a necessidade de investimentos permanentes de fluxo contínuo nos vários espaços educacionais e incentivo à interação otimizando a formação escolar e a eficiência deles, e para o fato de que os currículos escolares locais ainda não têm prestigiado devidamente os conhecimentos científico-culturais regionais, levando a uma formação básica deficitária por parte dos cidadãos. Em função desse déficit, percebeu-se que os cidadãos não têm adquirido os conhecimentos necessários para a compreensão de fatos relevantes à explicação científica do fenômeno astronômico observado e registrado na cidade há pouco mais de um século e que contribuiu notoriamente para comprovação da TRG.
J. Brodsky Creative Behavior in the Perception of Contemporaries
Authors:   Ural Federal University, Balandina Irina A.
Published: March 2024

The article examines the specifics of Joseph Brodsky’s creative behavior by comparing the image constructed by the poet himself with the vision of his contemporaries. The category of creative behavior, being crucial for the study, is seen as special features of the behavior of a creative individual — a poet and a creator — in society, aimed at forming a certain public image beneficial for the artist. Based on memorial articles and interviews dedicated to Brodsky, the main features of his creative image are marked out. The study of Brodsky’s creative behavior becomes an important milestone in the research of the global “Brodsky myth” and “the myth of Brodsky”, created in parallel with each other already during the poet’s lifetime. This paper shows that Brodsky’s creative behavior and his reception converge in the image of the poet, the key link of his self­identification and the myth that was formed in the society. The self­determination and definition of Brodsky by others primarily as a Poet becomes the basis of his creative behavior and perception, and its significance overlaps many other aspects of Brodsky’s complex personality.

Published: March 2024

Intercultural communication is an important component of modern higher education. This article examines the historical background, development status and existing problems of intercultural communication in Chinese education from a historical perspective. The results show that theoretical research on intercultural communication in China is mainly concentrated in the field of language learning, especially English. The analysis of issues of historical development of intercultural communication opens up opportunities for effective interaction in the field of education and ensures the successful integration of higher education systems into global mixed educational environment. Familiarity with issues of intercultural communication helps stimulate and develop the effectiveness of teaching a foreign language and cultural dialogue, and also helps Russian teachers and Chinese students to study more deeply the issues of intercultural communication in the field of education, and it also improves the quality of international education in theoretical and practical aspects.
