Biophysical stimuli for promoting bone repair and regeneration
Authors: Bai Yunyang , Li Xiaochan , Wu Ke , Heng Boon C. , Zhang Xuehui , Deng Xuliang
Published: July 2024

Bone injuries and diseases are associated with profound changes in the biophysical properties of living bone tissues, particularly their electrical and mechanical properties. The biophysical properties of healthy bone are attributed to the complex network of interactions between its various cell types (i.e., osteocytes, osteoclast, immune cells and vascular endothelial cells) with the surrounding extracellular matrix (ECM) against the backdrop of a myriad of biomechanical and bioelectrical stimuli arising from daily physical activities. Understanding the pathophysiological changes in bone biophysical properties is critical to developing new therapeutic strategies and novel scaffold biomaterials for orthopedic surgery and tissue engineering, as well as provides a basis for the application of various biophysical stimuli as therapeutic agents to restore the physiological microenvironment of injured/diseased bone tissue, to facilitate its repair and regeneration. These include mechanical, electrical, magnetic, thermal and ultrasound stimuli, which will be critically examined in this review. A significant advantage of utilizing such biophysical stimuli to facilitate bone healing is that these may be applied non-invasively with minimal damage to surrounding tissues, unlike conventional orthopedic surgical procedures. Furthermore, the effects of such biophysical stimuli can be localized specifically at the bone defect site, unlike drugs or growth factors that tend to diffuse away after delivery, which may result in detrimental side effects at ectopic sites.

Published: July 2024

In this study, brake linings with Cu (copper)-based and Cu-10Sn (bronze)-based matrix structures have been developed and produced by the powder metallurgy method using sinter metal technology for use in high-speed trains. The developed linings were compared with commercial high-speed train linings. Firstly, the mixing process was carried out in a Turbulo 3V three-dimensional mixer for 4.5 h at 50 rpm. The pressing process was performed at room temperature, under the pressure of 350–450 MPa, and the sintering temperature for Cu-based linings was 1,000 °C, while for Cu-10Sn-based linings, it was 800 °C. After the pressing and sintering processes, lining sample density calculations were conducted, and hardness tests were carried out in the Rockwell L scale. Shear strength tests, friction coefficient, and wear tests were conducted according to SAE J 661 standards. It was observed that sinter metal brake linings with Cu and Cu-10Sn main matrix structures showed similar properties and met the technical requirements. It was determined that the developed production prescriptions are promising for industrial production and patent studies.

Gender assignment in language contact
Authors: Levkovych Nataliya
Published: July 2024

This paper deals with an important aspect of the integration of loan nouns into the grammatical systems of languages attesting to grammatical gender, namely gender assignment. Traditionally, it is assumed that gender assignment takes place according to the internal assignment rules of the replica language. In many cases, however, the original grammatical gender is borrowed along with the source word. This is the case of gender copy which often takes place under special (sociolinguistic) conditions and is used as assignment strategy in languages to a different extent. A special focus of my study is on gender assignment and particularly gender copy in the contact of languages of different assignment types (formal vs. semantic). The empirical data comes from five European languages in different sociolinguistic situations, attesting to different assignment systems and of different language branches of two language families – Indo-European (Romanian, Slavic, and Indo-Arian) and Nakh-Daghestanian (Lezgic and Tsezic). The analysis shows that gender copy is possible mostly in the contact of languages of the same assignment type. In the contact of languages of the formal assignment type, gender copy often goes along with the formal adjustment of the loan word. Sociolinguistic circumstances play an important role as to the possibility and frequency of the occurrence of gender copy.
Probiotics: a promising intervention for osteoporosis prevention and management

Published: July 2024

Osteoporosis (OP) is a systemic skeletal disease that is characterized by low bone mass and increased fracture risk. This article explores the potential of probiotics as an adjunctive approach for the prevention and management of OP. It has been well established that the gut microbiota (GM), a complex community of microbes, plays an important role in bone health. The gut dysbiosis is linked with a higher risk of OP. However, the consumption of probiotics in adequate amounts restores gut health thus improving bone health. Probiotics may influence bone metabolism through enhanced calcium absorption, reduced inflammation, and increased bone formation. The animal and human studies demonstrate the positive effects of probiotics on bone health parameters like reduced osteoclastogenesis, bone resorption markers, osteoblast, osteocyte apoptosis, and increased bone mineral density and expression of osteoprotegerin. The current evidence suggests that probiotics can be used as an adjunctive approach along with the existing therapies for the prevention and management of OP.

KARDIOPROTEKTÍV STRATÉGIÁK A SZÍVIZOM ISZKÉMIÁS-REPERFÚZIÓS KÁROSODÁSÁVAL SZEMBEN
Authors: Oumaima El Alaoui El Abdallaoui , Komócsi András , Szokodi István
Published: July 2024

Bevezetés: Az ST-szegment elevációval járó szívinfarktus (STEMI) előfordulása az elmúlt két évtizedben a fejlett országokban csökkenést mutatott. A reperfúziós terápiához való széles körű hozzáférés ellenére azonban a STEMI-hez kapcsolódó halálozás továbbra is jelentős. 
Célkitűzés: Áttekintésünk átfogóan vizsgálja az akut szívinfarktus és a reperfúzió patofiziológiáját, felölelve az iszkémiás és reperfúziós sérülések kialakulását, a sejthalál különböző módozatait és az ebből eredő koszorúér-mikrovaszkuláris diszfunkciót. Végül részletesen tárgyaljuk a kardioprotektív gyógyszeres terápiák klinikai gyakorlatba való átültetésére irányuló erőfeszítéseket.
Eredmények: Bár a reperfúzió elengedhetetlen az iszkémiás szívizom megmentéséhez a fenyegető infarktustól, további irreverzibilis károsodást is okoz, ami az infarktus méretének növekedéséhez és mikrovaszkuláris diszfunkcióhoz vezet. 
Következtetés: Az infarktus mérete és a MVO a kardioprotektív kezelés két, egymással összefüggő terápiás célpontjának tűnik. Mindazonáltal a hatékony kardioprotektív stratégiák klinikai gyakorlatban történő alkalmazása továbbra is kielégítetlen orvosi igény marad.

The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC, 2019–2020), a year-long drift with the Arctic sea ice, has provided the scientific community with an unprecedented, multidisciplinary dataset from the Eurasian Arctic Ocean, covering high atmosphere to deep ocean across all seasons. However, the heterogeneity of data and the superposition of spatial and temporal variability, intrinsic to a drift campaign, complicate the interpretation of observations. In this study, we have compiled a quality-controlled physical hydrographic dataset with best spatio-temporal coverage and derived core parameters, including the mixed layer depth, heat fluxes over key layers, and friction velocity. We provide a comprehensive and accessible overview of the ocean conditions encountered along the MOSAiC drift, discuss their interdisciplinary implications, and compare common ocean climatologies to these new data. Our results indicate that, for the most part, ocean variability was dominated by regional rather than seasonal signals, carrying potentially strong implications for ocean biogeochemistry, ecology, sea ice, and even atmospheric conditions. Near-surface ocean properties were strongly influenced by the relative position of sampling, within or outside the river-water influenced Transpolar Drift, and seasonal warming and meltwater input. Ventilation down to the Atlantic Water layer in the Nansen Basin allowed for a stronger connectivity between subsurface heat and the sea ice and surface ocean via elevated upward heat fluxes. The Yermak Plateau and Fram Strait regions were characterized by heterogeneous water mass distributions, energetic ocean currents, and stronger lateral gradients in surface water properties in frontal regions. Together with the presented results and core parameters, we offer context for interdisciplinary research, fostering an improved understanding of the complex, coupled Arctic System.

Undoped and Chromium (Cr) doped (2, 4%) copper sulfide (Cu2S) nanostructured thin films were created by spray pyrolysis. The films were polycrystalline and combined cubic and monoclinic structures, according to the results of the XRD investigation. Surface roughness values for the doped and undoped thin films are 8.71, 7.79, and 3.24 nm, respectively. SEM images display Cu2S nanostructures with fine crystallites and traces of nanorod. Chromium doping increases particle size and induces nanorod growth, enhancing surface porosity. The optical examination shows that Cr-doped Cu2S thin films exhibit effective absorption (> 104 orders) in the visible range. From the change in absorption coefficient, it can be observed that there is a valley around 2.6 eV. By doping Cr (up to 2%) in Cu2S films, it is possible to control the band gap between 2.62 eV and 2.73 eV. The refractive index of undoped Cu2S films decreases with increasing Cr-doping concentration. Gas sensing of Chromium-doped and undoped Cu2S nanostructures involves dynamic resistance change at 100°C. Undoped Cu2S displays low resistance, exhibiting p-type semiconductor behavior. Notably, 4% Cr-doped Cu2S shows high resistance, and the introduction of NO2 decreases resistance. Decreased sensitivity with rising Cr doping in Cu2S: 2% Cr and Cu2S: 4% Cr. Responsiveness declined across different NO2 concentrations (200 ppm, 300 ppm, and 400 ppm).
Use of Modern Tools in the Formation of Strategic Goals of the Institution of Higher Education
Authors: Verbovska Lesya
Published: July 2024

The article examines the issue of the development of a higher education institution in conditions of change. A comparative analysis of the development strategies of four higher education institutions was carried out. The expediency of using SWOT analysis in the process of elaborating development and internationalisation strategies is substantiated. The SWOT analysis of domestic universities is provided, and the main results of the research in the field of international activities are presented. It is shown that the strategic process for universities is a rather effective and necessary tool for attracting stakeholders, the ability to take into account global trends in the development of higher education in modern conditions of change. It is shown that in the modern conditions of global changes the issues of formation and achievement of strategic goals are of particular importance for higher education institutions. For example, the priority “Creation of a favourable environment for attracting investments” is not a matter for the university alone, as this process requires the coordinated work of institutions and business entities. It was noted that it is important to take into account and coordinate the actions of all stakeholders, as they are the main agents of change, serving or ensuring the implementation of the necessary changes. A comparative analysis of the strategies of four universities made it possible to identify their strategic goals, mission and directions of development. The study showed that two universities used the SWO T analysis tool to describe the strategy, and opportunities for further development were identified. At the same time, we can say that the goals and priorities of the analysed universities are in line with the Sustainable Development Goals. The necessity to develop a strategy for the development of the higher education institution in terms of the internationalisation strategy with the use of SWOT analysis is substantiated.

Authors: Sugiaman Vinna Kurniawati , Jeffrey Jeffrey , Widowati Wahyu , Ferdiansyah Rival , Novianto Agung
Published: July 2024

Gingivitis inflammation triggered by microbial biofilms is one of the detrimental causes of periodontal diseases. When a periodontal disease occurs, tooth decay becomes inevitable, and can pose a serious threat to oral health, requiring appropriate treatment. Inflammation in periodontitis is mainly caused by oxidative stress; hence, antimicrobial and antioxidant-based therapies are suggested for periodontitis. Sappan wood is well-known for its brazilin compounds, which have the potential as herbal medicines and antibacterial agents to fight oral pathogens with minimal side effects. This study aimed to examine the antimicrobial and antioxidant activities of sappan wood extract (SE) as a candidate agent for preventing periodontal diseases. This study was conducted at Maranatha Christian University, Sekolah Tinggi Farmasi Indonesia, and Aretha Medika Utama from January-April 2023. The sappan wood was extracted using ethanol 96% and the antimicrobial evaluation was done by calculating the total colony of P. gingivalis while the antioxidant activity was evaluated by ABTS, H2O2, and FRAP Assays. This study revealed that SE was significantly effective in reducing the total colony of P. gingivalis up to 0 CFU/mL. The highest antioxidant activity of SE was found in 100 µg/mL with IC50 19.06 µg/mL for ABTS, 90.99 µg/mL for H2O2, and 564 µM Fe (II) for FRAP. Thus, SE presents its strong antimicrobial and antioxidant activity potentials by in vitro evaluation that could be analyzed further for its utilization as a periodontal-preventing agent. This study also provides basic information for future implication of sappan wood extract as ingredients for dental care products.

The role of physical exercise in the treatment of chronic diseases: an epigenetic approach
Authors: Hernandez Quintero Julian Andres
Published: July 2024

Chronic non-communicable diseases (NCDs) such as type 2 diabetes, cardiovascular diseases, and obesity present a significant public health challenge worldwide. Physical exercise has emerged as an effective intervention for managing and preventing these conditions. Recent epigenetic research has shed light on how exercise can influence gene expression, offering a novel perspective on its impact on NCDs. This review examines the role of physical exercise in modulating the expression of genes associated with NCDs from an epigenetic standpoint. We discuss key genes implicated in chronic diseases, such as FTO, PPARγ, and GLUT4, and their regulation through different types of exercise, including aerobic capacity and strength training. Evidence suggests that aerobic exercise can reduce methylation of genes like PGC-1α, enhancing mitochondrial biogenesis, while strength training influences genes like IGF-1, promoting muscle growth and regeneration. Understanding these epigenetic mechanisms provides new insights into personalized and effective interventions for chronic disease management.

Síndrome de la arteria mesentérica superior en una paciente con leucemia linfoblástica aguda. Reporte de caso
Authors: Bustos-Guerrero Ada Mercedes , Alfonso-Valderrama Osman Osvaldo
Published: July 2024

Resumen
Introducción. El síndrome de la arteria mesentérica superior, también llamado síndrome de Wilkie, ocurre por la disminución del ángulo aortomesentérico con compresión de la tercera porción duodenal. La sintomatología en muchos casos es inespecífica y su etiología se presenta por causas relacionadas con disminución de la grasa mesentérica. El diagnóstico se basa en hallazgos imagenológicos y endoscópicos. Su tratamiento se enfoca en corregir la causa relacionada con la pérdida de peso y, en casos refractarios, está indicado el manejo quirúrgico.
Presentación del caso.  Mujer de 19 años que asistió a una institución de tercer nivel de complejidad en la ciudad de Bucaramanga (Colombia), por sintomatología de 2 meses consistente en pérdida de peso y pérdida parcial del apetito. Las pruebas de sangre mostraron anemia e hiperleucocitosis con 37% de blastos, por lo que se hizo dictamen de leucemia linfoide aguda diagnosticada por aspiración de médula ósea. Durante su estancia hospitalaria presentó dolor abdominal, vómito e intolerancia a la vía oral. En la tomografía de abdomen se observó distensión de la tercera y cuarta porción duodenal y una reducción del ángulo aortomesentérico (18.8º), lo que generó una obstrucción mecánica proximal del intestino. Se inició manejo médico, nutrición parenteral total y terapia postural postprandial. En imágenes de vías digestivas de control se evidenció un adecuado paso de medio de contraste hasta el yeyuno. La paciente toleró el inicio de la vía oral y presentó una buena evolución clínica.
Conclusiones. El síndrome de la arteria mesentérica superior es una causa poco frecuente de obstrucción intestinal con características clínicas variables, por lo que se requiere una alta sospecha diagnóstica. Se deben realizar estudios imagenológicos para confirmar el diagnóstico e iniciar manejo médico de forma temprana para evitar posibles intervenciones quirúrgicas.

Authors: Razo-González Angélica-María , López-González Martha-Patricia
Published: July 2024

La identidad es una elaboración personal construida con base en la interacción dentro de un contexto histórico sociocultural. La identidad masculinidad tiene su cimiento en los roles de género, que influyen y determinan el comportamiento de los hombres. El objetivo fue analizar el significado psicológico de la identidad masculina en hombres de diferentes generaciones. En la metodología mixta se aplicó la técnica de redes semánticas a 268 hombres, de tres cohortes generacionales y de la diversidad sexual. Los resultados muestran que el concepto “ser hombre” está bien definido en las tres poblaciones, siendo los jóvenes y los de la diversidad quienes, con el paso de la modernidad a la posmodernidad, se ven obligados a la transformación de su identidad masculina.
Pandemia: ¿del mercantilismo a la humanización? Las pedagogías de lengua extranjera: ¿un alto a su estandarización?
Authors: Castañeda Nieto Ricardo
Published: July 2024

Con el paso del tiempo, los procesos de enseñanza y de aprendizaje de una lengua extranjera se han venido ajustando a los de una segunda lengua, a pesar de las sustantivas diferencias contextuales en que ellos se desarrollan. Factor de importante incidencia en la homogeneización de las dos disciplinas lo constituye el material didáctico y de evaluación implementados sin distingo alguno en ambos procesos. Lo inadecuado de tal procedimiento demanda de las entidades gubernamentales, de la mano de sus instituciones de educación superior, la formulación de políticas lingüísticas auténticas, la concepción de material didáctico autóctono de base, en apoyo del particular escenario sociocultural en que se enmarca la formación en lengua extranjera. La presente exposición busca suscitar, asimismo, consideraciones en torno al concepto de internacionalización (en estrecha relación con la problemática planteada), sobre la base del respeto por la alteridad y su diversidad cultural.
Hifomicetos acuáticos en México, América Central y el Caribe y su potencial aplicación como bioindicadores de calidad ambiental
Authors: Fernandez Da silva Rafael , Smits Briedis Gunta
Published: July 2024

Los hifomicetos acuáticos son microorganismos fúngicos anamórficos de cuerpos de agua lóticos prístinos, que participan en la degradación de material vegetal en el mismo, facilitando el reciclaje de nutrientes en los ecosistemas dulceacuícolas, siendo importantes ecológicamente por ser potenciales bioindicadores de calidad ambiental, aunado a presentar una amplia gama de enzimas de relevancia biotecnológica. Las investigaciones de estos organismos son pocas en la región Neotropical, como en la subregión de América latina conformada por México, América Central y el Caribe, donde se ha registrado un total de 236 especies, 109 Ingoldianas, 24 aero acuáticas y 103 transicionales, siendo Puerto Rico el país con el mayor numero de reportes (135; 74,8% Ingoldianos), seguido de Cuba (73; 52% transicionales), aunado al escaso estudio (solo dos trabajos) de estos como indicadores de calidad, donde se demuestra su rol como bioindicadores. Por lo cual esta revisión busca ser la base para impulsar nuevas investigaciones con este grupo fúngico, a fin de incrementar su registro, validando que la zona tropical es la de mayor biodiversidad, aunado al futuro establecimiento de índices biológicos de calidad ambiental con estos hongos, para su uso ecológicamente sustentable.
Áreas naturales protegidas urbanas ¿Figuras de conservación y uso sostenible o relictos de vegetación en vías de extinción?
Authors: Carrillo Reyna Natalia Lucia , Rosete Vergés Fernando Antonio , Ruíz López Rodolfo
Published: July 2024

Las
áreas naturales protegidas urbanas se encuentran en peligro de perder su función principal, que es el manteni- miento de la biodiversidad, por su aislamiento y las presio- nes que enfrentan al estar inmersas en zonas urbanas. Por ello, es imprescindible comprender las interacciones entre lossistemas sociales y ecológicos que pueden afectar su funcionalidad ecológica. El objetivo de esta investigación fue realizar una evaluación de la aplicación de la norma- tividad ambiental a usuarios en tres Áreas Naturales Pro- tegidas (ANP) en Michoacán, México, así como conocer los cambiosen la cubierta vegetal y usos de suelo dentro de las reservas en los años en los que han estado bajo pro- tección. Para ello, se realizaron entrevistas a actores locales como colonos y usuarios de las áreas de influencia y admi- nistradores de las ANP, y se elaboró un diagnóstico para conocer el nivel deaplicación de las normas ambientales. Para conocer que tanto han sido preservados y restaurados los ecosistemas dentro de las ANP, se realizaron mapasde cambio de la cubierta vegetal y uso de suelo en un periodo de 26 años (1995-2021). Los resultados muestran desco- nocimiento del manejo de lasANP y desapropiación de los pobladores y usuarios. Los administradores reconocen una falta de gobernanza ambiental generalizada, pero rea-lizan un trabajo arduo para procurar su correcto funciona- miento. Los mapas de cambio en dos ANP muestran la diminución de la cubierta forestaly los cuerpos de agua, así como cambios la estructura y composición forestal.

Authors: Maria Maria Elisa Sarmento Costa , Soares Juliano Lima
Published: July 2024

As cooperativas agropecuárias têm um papel importante na promoção do agronegócio brasileiro. Diante desse cenário e dos desafios enfrentados por elas, torna-se necessário o alinhamento entre eficiência na gestão dos negócios e adaptabilidade às mudanças, a fim de equilibrar as ações de exploitation e exploration, e obter uma cadeia de suprimentos bem integrada. O objetivo desta pesquisa foi analisar qual a relação entre o grau de verticalização e a ambidestralidade (ações de exploitation e exploration) em cooperativas agropecuárias brasileiras que estão localizadas no estado de Goiás. Trata-se de um estudo em que se analisam os construtos “verticalização” e “ambidestralidade”. O estudo foi realizado a partir da aplicação de um questionário às cooperativas e em que foram utilizados os dados referentes ao Censo do Cooperativismo Goiano de 2019. Os dados foram analisados com base na análise de cluster e em testes de média não paramétricos. As maiores contribuições do estudo relacionam-se à observação do crescimento do grau de vertacalização, que se refere à realização de maior quantidade de atividade dentro da cadeia das coooperativas agropecuárias, e da ambidestralidade, uma vez que se observou a tendência de que quanto maior média do grau de ambidestralidade nas cooperativas, mais ações de exploitation e exploration realizam quando comparadas às demais.

Published: July 2024

One of the problems investors often face is deciding on the stocks to include in an investment portfolio. Hence, this article seeks to select investment portfolios considering the 30 leading companies listed on the New York Stock Exchange (NYSE) of the Dow Jones Index. Portfolio selection in this index is carried out by generating a previous ranking of the shares with a novel approach that analyzes their performance using a multiple criteria hierarchical process (MCHP). The current research allows the evaluation of shares and optimizing a portfolio, while developing a procedure that supports a decision-making process for organizations or practitioners to invest in the stock market. The results of analyzing the NYSE generated a portfolio that can be used for interested investors. The main contribution of the application of MCHP and Markowitz model is related to the possibility of replicating the developed procedure to select portfolios in other stock markets.
Don Quijote y Dulcinea en Bogotá: Un tal Alonso Quijano (2020) de Libia Stella Gómez
Authors: Botero García Mario Martín , Jiménez Ruiz Federico
Published: July 2024

Este artículo examina la interacción entre el Quijote de Cervantes y su transmutación cinematográfica en Un tal Alonso Quijano de Libia Stella Gómez (2020), a través de los personajes de don Quijote y Dulcinea. Partimos de una consideración sobre el tipo de apuesta adaptativa y el cambio de medio semiótico que propone Un tal Alonso Quijano, con base en lo cual comparamos algunos aspectos de ambas historias. Después analizamos la interpretación y desarrollo original de los personajes de don Quijote y Dulcinea presentes en el filme, específicamente, como bogotanos del siglo XXI que, en medio de la frustración, eligen portar una máscara. Sin embargo, al final, en un proceso de desencantamiento, comprenderán que deben afrontar sus miedos sin recurrir a la impostura. Así, la propuesta de Gómez confiere a los personajes una nueva configuración que en el fondo contribuye a mantener vivo el mito cervantino.
Political Ideology and the Legitimization of Social Inequalities in Colombia
Authors: García-Sánchez Efraín , Palacio-Sañudo Jorge , Romero Royert Daniela
Published: July 2024

This article examines the effect of left-right political ideology on attitudes toward inequality and the maintenance of the status quo in Colombia. In three studies, we examined the influence of political orientation on attitudes towards economic inequality (Study 1, N = 506), gender inequality (Study 2, N = 277), and political inequality (Study 3, N = 1,555). Our results suggest that people positioning further to the right on the political spectrum —political conservatism—were consistently associated with lower perception of social inequalities, greater justification of the unequal status quo, and refusal to take actions that redress inequality. These results were consistent across different domains, such as economic, political and gender inequalities. Furthermore, our findings also suggest that political ideology was also associated with political and affective polarization. Political ideology is discussed as a category that allows people to perceive and understand the social world from which they position themselves in relation to political issues.

El ciclo del nitrógeno representa uno de los procesos biogeoquímicos más importantes para los ecosistemas terrestres y acuáticos. Las comunidades microbianas desempeñan un papel crucial en los procesos de transformación del nitrógeno en el suelo, ya que participan en diversas etapas como la nitrificación, de gran importancia para la producción agrícola. Dentro de los marcadores moleculares más utilizados para evaluar la actividad de poblaciones microbianas oxidantes de amonio se han considerado ampliamente los genes que codifican enzimas claves como la subunidad A de la actividad amonio monooxigenasa (AMO). Sin embargo, no se comprende completamente si la expresión de esta enzima tiene relación directa con el rendimiento de los cultivos. En este contexto, se evaluó la expresión del gen amo-A de comunidades bacterianas y archaeales presentes en un lote arrocero previamente caracterizado por ambientes. Para cuantificar la abundancia de arqueas y bacterias oxidantes de amonio, (AOA y AOB, respectivamente) se emplearon las técnicas de PCR en tiempo real (RT-qPCR) y PCR digital (RT-dPCR). En este trabajo se encontró a través del análisis de datos metagenómicos que hubo una mayor presencia de AOB en las muestras de suelo rizosférico mientras que las AOA fueron predominantes en las muestras de suelo de soporte “bulk”, sin embargo, no se detectó la expresión del gen amo-A asociada a la comunidad de bacterias en las muestras de suelo analizadas. Por otra parte, no se presentaron diferencias entre los transcritos del gen amo-A asociados a la comunidad de AOA de los ambientes caracterizados. Además, la expresión de transcritos no estuvo relacionada con alguna de las propiedades químicas evaluadas. Finalmente, las estrategias de cuantificación para RT-qPCR (plásmido y templete) resultaron ser homólogas y funcionales para identificar la expresión del gen amo-A de AOA, mientras que la técnica de RT-dPCR fue más precisa para el análisis de la comunidad de AOB y AOA.

Introduction. The risks of destabilization of the ethno-political and ethno-confessional situation in the North Caucasus, active migration processes, as well as traditional for this macro-region socio-economic problems and issues of inter-ethnic relations actualize the state policy of identity at the level of regions and the country as a whole. One of the mechanisms for strengthening the Russian national identity is regional branding. The purpose of the study is to analyze the perceptions of the region's uniqueness, values, levels of identity of the population of Adygea, Kabardino-Balkaria and Dagestan, to find common meanings and values for the regions, which, reflected in brands, are included in the state identity policy, strengthening its national level.

Materials and Methods. Empirical materials include quantitative data from a mass survey conducted in October-November 2023 in Adygea, Kabardino-Balkaria and Dagestan, and qualitative (non-standardized interviews with experts). The methodological design is based on the use of an interdisciplinary approach and comparative analysis of cases from the three regions. This allowed us to identify common and special features in determining the potential of branding to strengthen the Russian national identity, based on the principle of triangulation.

Results. The peculiarities and key characteristics of the regions under study have been identified. It was found that there is no integral established brand of the region in them, but the sources of its formation are obvious - the residents' perceptions of the uniqueness of the region and the markers by which the residents identify themselves with it. In Adygea and Kabardino-Balkaria it is a high level of comfort with the preservation of ethnic traditions, in Dagestan it is the significant role of religion and ethnic traditions, active orientation of residents to entrepreneurial activity.

Discussions and Conclusions. Regional identity is formed around unique unifying features ‒ the value of preserving ethnic traditions and good-neighborly relations, the absence of interethnic conflicts, identification markers common to the three regions (attitude to the native land, nature, territory, the value of cultural traditions, language). The reliance on these values in the process of branding the regions provides a link to national identity through the meanings and values common to all regions. The obtained results may be of interest to regional authorities and contribute to the inclusion of regional branding tasks in the policy of strengthening national identity.

[Land Suitability Modeling for Fishery Resource Enhancement in the Padang Pariaman Regency, West Sumatera, Indonesia: GIS and Multi-Criteria Evaluation Approaches] Land suitability analysis is required for successful aquaculture planning. Due to the geographical setting of the Padang Pariaman Regency, aquaculture development is likely hindered by the vulnerable coastal area. Suitability assessment of aquaculture projects is crucial to specify the best method espousing sustainable development in the study area. This study aims to select the most proper location to be developed as a center of shrimp aquaculture in the Padang Pariaman Regency. This study employed the multi-criteria decision-making (MCDM), and analytical hierarchy process (AHP) approaches. This study combined the GIS-based analysis, AHP, and MCDM to yield the most proper location for aquaculture development. The three sub-models (engineering, water quality, and infrastructure) are overlaid using the weighted linear combination (WLC) technique. The infrastructure sub-model resulted in the highest coverage of highly suitable criteria with 61.74%. By contrast, the highest percentage of the unsuitable category was found in the water quality sub-model with 17.67%. Of particular concern, 87.5 % of the study area is suitable for aquaculture development. The remaining region is categorized as highly suitable with 11.93%, found in the eastern Padang Pariaman. Thus, we conclude that developing shrimp aquaculture in the study area is possible. Still, the future environmental impacts should be considered beforehand.
‘The Quakers tea table overturn’d’
Authors: Stainforth Elizabeth , Wilson C Anne
Published: July 2024

This article was developed from research undertaken for an exhibition of creamware co-curated by students on the MA in Art Gallery and Museum Studies at the University of Leeds in 2010. The exhibition, titled ‘Vanity Ware: Affordable Luxury in the Late Georgian Period’, related the production of creamware to the contemporary popularity of beverages such as tea and the emergence of an aspirational and upwardly mobile middle class in the eighteenth century. The article explores the moral panic that the practice of tea drinking by young ladies often evoked in certain religious circles.
