Changing the Picture and Music for Hope: Cultural Expressions of Solidarity in the UK with El Salvador at the End of the Cold War
Authors: Bradbury Pablo , Redden Andrew , McIndoe Emily
Published: September 2024

This paper focuses on UK-based cultural expressions of international solidarity with El Salvador either side of the end of the Cold War and El Salvador’s civil war. The article centres on a mural titled Changing the Picture, painted in Greenwich from 1985, which depicts a message of hope for overcoming state repression sponsored by multinational capital and Western powers; and Music for Hope, an ongoing musical education programme beginning in 1996-7 based in the Bajo Lempa, a coastal region of El Salvador, but set up and supported by a British solidarity network. After exploring the political meanings and initiatives of solidarity in the UK during the Salvadoran civil war, we analyse Changing the Picture’s central message of anti-imperialism, the depiction of collective popular struggle and the artwork’s place within the cultural politics of London in the mid-1980s. The paper then examines how the communitarian message of popular democracy present in the mural has been articulated in new cultural forms by Music for Hope, particularly through the latter’s pedagogical, horizontal and prefigurative practice of teaching music to children and adolescents and encouraging the formation of musical groups. As such, this paper foregrounds cultural and artistic practice as a central but underexplored dimension of international solidarity. Highlighting the literature on the shift in political culture, produced by the culmination of the Cold War, from a frame foregrounding revolutionary or political struggle to one centred on trauma, we explore how Changing the Picture and Music for Hope reflect different historical conditions. If the solidarity depicted in Changing the Picture reflected the final years of a period in which the revolutionary horizon was considered possible, Music for Hope emerged at a time that forced the initiative to confront the traumatic legacies of the civil war years. Despite these differences, the article argues that there is far more that connects the two examples, especially their emphasis on community agency. In doing so, we show that artistic expression can not only represent a powerful medium through which solidarity politics are communicated, condensing both local and international contexts in a radical vision of hope, but that cultural action can also structure the participatory practice frequently at the heart of international solidarity politics.
The Semiotics of Solidarity: Reinterpreting Artefacts of Latin American Resistance in Contemporary Leeds
Authors: Grimaldi Anna , Smith Richard
Published: September 2024

This paper examines reinterpretations of solidarity with Latin America through a student-led project at the University of Leeds. The project, ‘Thinking Inside the Box: 1973’ (hereafter, TITB), was a collaboration between the University of London – specifically, King’s College London, Queen Mary University of London, and the London School of Economics – and the Universities of Leeds and Liverpool in 2023. The broader framework of TITB seeks to generate liberatory and transformative learning by approaching the educative process with students as co-creators and co-curators of knowledge. The approach draws from decolonial theory by seeking to challenge the hierarchical practices of mainstream education in which the teacher imposes knowledge on the student. In dialogue with Freirian concepts of collective interpretation and ‘conscientisation’ (Freire, 1968), scholars and students involved in the project used archives to run a series of events and public engagements. It connects students to each other and to a range of archival materials, broadly themed around 20th century Latin America, to inspire them in designing, developing and delivering an output of significant impact by engaging with local communities; in this case, the Chilean diaspora of the dictatorship. The project promotes the co-curation of knowledge, teaching and learning, and supports students to practice autonomy in their journeys of content and skills acquisition (Grimaldi, Carvalho and Natale, 2022; Grimaldi and Rofe, 2023).
¿Why Leeds?
Authors: Martinez Relano Elisa
Published: September 2024

The following piece was written by Elisa Martinez Relano in 2023. Inspired by a student-led project exploring past and present solidarities with Latin America, Elisa, now completing an MA in the History of Art and Social History at the University of Leeds, wrote the following text. Her reflection on archival research around Chilean exile in the 1970s takes place in 2023, fifty years after the infamous coup, and is guided by a simple question: how and why would Leeds engage in solidarity activism with a place as seemingly distant as Chile?

This contribution pieces together elements of the project website, extracts of their archival work and reflections from the project collective.
Uses and Abuses of the Conquista
Authors: Mejias Ulises
Published: September 2024

Spanish people can detect my Mexican accent as soon as I open my mouth, and it’s interesting to see their reactions during my travels through that country. Most Spaniards are kind and curious. But I do remember a taxi driver who convivially told me that, to be sure, Spain had done horrible things to Mexico, but that I should still think of Spain like a father — a drunk and abusive father, in his words, but a father nonetheless.
One can take such remarks about colonialism in stride and with good humor when they come from a taxi driver. But it is difficult to swallow similar arguments when they come from historians like Fernando Cervantes, author of Conquistadores: A New History of Spanish Discovery and Conquest.

Sustainable development of domestic agriculture and self-sufficiency of the population with food products under sanctions
Authors: Skvortsov Egor A. , Skvortsova Ekaterina G. , Chepushtanova Olga V.
Published: September 2024

The introduction of foreign economic restrictions (sanctions) was a significant challenge for the sustainable development of agriculture. To assess the sustainable development of the industry under the conditions of sanctions, an analysis was carried out on a number of indicators, while the calculations used data for two periods - the control stage (2014-2021) and for the period of strict foreign economic restrictions (2022-2023). Agricultural production at the end of 2023 increased by a record 11.6% compared to the “pre-sanctions” year 2021, while the average annual growth rate for 2014-2021 was 8.7 percent. For all types of agricultural products, there is an increase in per capita production values in 2022 (grain – 30.1%, meat – 3.6%, milk – 2.3%). Indicators of domestic production to consumption for the main types of agricultural products remained stable. The population’s supply of basic food products has increased for a number of products. The analysis performed will allow us to conclude that at the current stage, foreign economic restrictions (sanctions) have a weak impact on the sustainable development of agriculture. However, the study of these issues in the medium and long term remains relevant.

Published: September 2024

Habronemosis is one of the main helminthiasis that affect horses, and has a global distribution. The present study focuses on cutaneous habronemosis, also known as Summer Wound. The diagnosis of cutaneous habronemiasis consists of observing clinical signs and identifying the larvae in a skin scraping or biopsy of the lesion. Furthermore, it is possible to state that horses have particular characteristics when it comes to wound healing. However, integrative therapies have proven efficient in this process through their pharmacological properties such as larvicidal, antioxidant, analgesic, anti-inflammatory, fungicidal and antitumor activity. In this sense, the present work aimed to evaluate the effectiveness of integrative therapies in the wound healing process in horses. The research was carried out using the descriptive qualitative method linked to a case study, obtained through medical records provided by the Oeste Horse specialized equine medicine team, in the region of Barreiras, Bahia. Thus, the present report is the case of an equine animal, of the quarter horse breed, male, castrated, weighing 450 kg, and ten years old, with habronemosis. After symptomatological and diagnostic evaluation, treatment was carried out using ivermectin oral paste, injectable triamcinolone and topical treatment [Daily cleaning with 0.9% saline solution, 10% povidone iodine, ointment with antibiotic therapy, daily dressing, use of laser therapy and essential oils]. As a result, it was possible to achieve complete healing of the wounds in 45 days with the complete clinical rehabilitation of the animal.

Introduction: La Casa de las Lenguas, a language centre at the University of La Rioja (Spain), offers the course “Let’s Read” designed as a book club that allows students to read and discuss short stories in English by authors from different countries and periods. Creative writing workshops are used alongside a more conventional approach to literature in the university course “Contemporary Narrative in English.” Methodology: This article aims to use the experience gained from teaching these courses to propose a combination of an English language book club with a creative writing workshop in the ESL university classroom. This university teaching experience is designed both to enhance language proficiency in English and to foster creativity and critical thinking. Results: Sessions are designed to work on the skills of listening, speaking, reading, and writing in English. Activities include an introduction to the author and their socio-cultural context, the reading/listening of the selected text, reading comprehension exercises, guided discussions, and creative writing tasks. Discussion and conclusions: The experience gained suggests that the benefits of this proposal include students’ improvement in language skills, greater motivation to learn a foreign language and engage in its culture, and the cultivation of creativity and critical thinking.
Reinventing self-promotion as an innovative teaching tool
Authors: Mateo Navarro Francisco , Lara Antonio
Published: September 2024

Television self-promotion remains largely unknown in audiovisual education and is often ignored in most academic works. The objective of this project is to highlight the value of this profession as a potentially essential tool for teaching students the various disciplines involved in producing an audiovisual piece, focusing especially on scriptwriting, which we consider the backbone of any audiovisual project, but also including direction and post-production. The methodology that has been followed is, firstly, a review and update of pioneering methods of teaching innovation, related to practice, such as Learning by Doing or Service Learning (ApS). The results section presents the development of the specific program that guides students to collaborate in groups, rotating in each piece by specialty. In the discussion section, we evaluate the extent to which the format of self-promotion is a better teaching tool than other types of pieces such as short films. The conclusions of the study indicate that using real assignments directly from industry examples stimulates the students by connecting them with tangible objectives while inspiring their imagination by compelling them to make creative decisions.

COMBINED EFFECT OF LAPAROTOMY AND EXPERIMENTAL POST-TRAUMATIC STRESS DISORDER ON THE SOURCES OF SUPEROXIDE ANION RADICAL IN THE RAT HEART
Authors: Ryabushko R.M. , Boiarska Z.O. , Kostenko V.O.
Published: September 2024

The aim of this study was to determine the sources of superoxide anion radical (O₂⁻•) in rat heart homogenate under conditions of surgical trauma inflicted against the background of an experimental model of posttraumatic stress disorder (PTSD). Materials and methods. The experiments were conducted on 42 white Wistar rats weighing (220±10) g, divided into 6 groups: Group 1 – intact animals; Group 2 – rodents with PTSD modeled by reproducing single prolonged stress (SPS); Group 3 – rats that underwent a sham operation; Group 4 – animals that underwent laparotomy; Group 5 – rats that underwent a sham operation after SPS modeling; Group 6 – animals that underwent laparotomy after reproducing SPS. The rate of O₂⁻• generation in the heart homogenate was studied using a spectrophotometric test with nitroblue tetrazolium. Results. The modeling of PTSD (SPS) and surgical trauma leads to a significant increase in oxidative stress in the rat heart, evidenced by an elevated rate of O₂⁻• generation involving NADPH-dependent electron transport chains (ETC) in microsomes, NO synthase, the mitochondrial respiratory chain, and leukocyte NADPH oxidase. In the post-laparotomy period following SPS, the oxidative stress enhanced significantly and was manifested through increased O₂⁻• generation by NADPH-dependent microsomal and NO synthase ETC by 72.3%, by NADH-dependent mitochondrial ETC by 72.9%, and leukocyte NADPH oxidase by 80.9% compared to intact control. When compared to group 2, these indicators rose by 29.6%, 24.4%, and 26.8%, respectively. Group 4 demonstrated an even more pronounced increase in O₂⁻• generation, reaching 54.0%, 54.6%, and 62.9% respectively. Furthermore, O₂⁻• production rates from all sources in group 4 were likely higher than those in group 5 by 29.8%, 21.2%, and 21.5% , respectively. Conclusions. The combined effect of laparotomy and experimental PTSD synergistically enhances O₂⁻• production in the heart homogenate from various sources, significantly exceeding the levels observed with either laparotomy or SPS alone.
Effects of Catechins on the Formation of Collagen Fibrils in vitro
Authors: Tarahovsky Yu. S , Gaidin S. G , Kim Yu. A
Published: September 2024

Some aspects of therapeutic action of catechins are associated with their effects on the deposition of collagen fibrils in tissues. It is assumed that this process is controlled through signaling and regulatory pathways in cells that catechins affect, however, the direct interactions of polyphenols with structural proteins cannot be excluded. The present work investigates the direct effect of (+)-catechin and epigallocatechin gallate on the formation of collagen fibrils in vitro. Turbidimetty, differential scanning calorimetry and transmission electron microscope data showed that (+)-catechin accelerates the formation of type I collagen fibrils, and the resulting fibrils have a protein-specific structure and thermal stability, while epigallocatechin gallate at a concentration of 10 μM inhibits fibrillogenesis. The results obtained expand our understanding of the potential mechanisms of therapeutic action of catechins demonstrating the possibility of a direct interaction of (+)- catechin and epigallocatechin gallate with collagen monomers and collagen fibrils and these findings may be useful in the development of new drugs containing these plant polyphenols or their synthetic analogues.
Innovative Biophysical Approaches for Quercetin Extraction from Plant Cells

Published: September 2024

The method for the extraction of quercetin from plant cells with the use of ultrasound in combination with metastable fraction from aqueous solution is proposed. The procedure enabled more efficient isolation of the cytoplasmic part due to etching and/or mechanical destruction of the cell membrane. The oxidized water fraction has the most pronounced extracting properties, but changes the properties of quercetin by oxidizing the chromophore part of the molecule. According to the criterion of pigment preservation, the best extraction solution is the reduced water fraction. To analyze the extract samples the following analytical methods were used: UV-Vis spectrometry, protein gel electrophoresis, 1H-NMR spectrometry, and QCM weighing, as well as scanning electron microscopy.
Adaptive Self-Defense of Mature Cells against Damage Is Based on the Warburg Effect, De-Differentiation of Cells and Resistance to Cell Death
Authors: Schwartsburd P. M
Published: September 2024

This review analyzes the hypothesis of the preserved ability of various specialized mammalian cells to protect themselves from lethal injury by enacting a protective atavistic mechanism of cell dedifferentiation. The development of such protection is accompanied by a transition of differentiated cells from the mitochondrial oxygen-dependent type of metabolism to regenerative oxygen-independent metabolism (called the Warburg effect). This transition allows cells to increase the resistance to cell death from hypoxia, and can also induce the emergence of fetal markers characteristic of cell dedifferentiation. This paper, exemplified by the development of two pathologies (heart failure and type 2 diabetes), presents the findings that confirm the existence of such a mechanism and ways of its possible correction.

Published: September 2024

The FLASH effect of high-energy (660 MeV) proton irradiation using the Phasotron accelerator with the capacity of delivering dose rates of 80 Gy/s has been studied and compared to the effect after exposure to proton radiation at a conventional dose rate of 3 Gy/min. After FLASH and conventional dose-rate irradiation with doses of 1.0 and 1.5 Gy, the induction of cytogenetic damage to bone marrow cells and the state of lymphoid organs (thymus and spleen) were estimated; at doses of 7.0 and 8.0 Gy, the survival rate after total irradiation of mice in vivo was analyzed; and at doses of 40 and 60 Gy, the tumor growth rate was determined after irradiation ex vivo. It has been shown that irradiation of animals using the FLASH mode at a dose of 1.5 Gy protects the proliferative activity of the spleen and also leads to a decrease in cytogenetic injuries in bone marrow erythrocytes, based on the micronucleus test, as compared to the conventional irradiation at a dose of 1.5 Gy; thus, the FLASH effect has lower toxicity compared to conventional radiation. However, irradiation of mice, the FLASH effect which delivers high doses (7.0 and 8.0 Gy) of radiation, leads to earlier death of animals compared to those exposed to conventional radiation. Only after FLASH irradiation of a suspension of Ehrlich ascites carcinoma at a dose of 40 Gy, a tumor node with further growth was formed; no tumors were formed in all other groups.

Published: September 2024

Until the middle of the last century, the Palearctic-Siberian gastropod fauna that inhabited the ‘sors’ and small coves of the larger bays of Lake Baikal was similar in environmental factors to Siberian water-bodies. Endemic species occupied open areas of the lake, with cold water, strong storms, and other specific environmental conditions. Based on morpho-anatomical characters and genetic distances of the COI mtDNA gene fragment between related species, five alien species were identified from open Baikal waters. In addition to the previously found Radix auricularia (Linnaeus, 1758), there were Radix cf. zazurniensis (Mozley 1934) (Lymnaeidae), Cincinna sorensis (Dybowski 1886) and C. cf. korotnevi Lindholm 1909 (Valvatidae), as well as Gyraulus cf. acronicus (Férussac 1807) (Planorbidae). A schematic map of the records of the alien species in the open littoral of the lake is presented, based on material taken by expeditions carried out in 1993–2023, as well as photographs of the shells and reproductive organs for some of the alien species, and information on coexisting endemic species of gastropods are given. We found albino individuals among R. auricularia and a few snails of R. cf. zazurniensis with afallic copulatory organs. Possible reasons for the invasion of the alien species and possible invaders into the open waters of Baikal are discussed.
Description of a well-known Western Palearctic species of the genus Reptalus Emeljanov 1971 (homoptera, auchenorrhyncha, fulgoroidea, cixiidae) that haS NO valid name

Published: September 2024

Reptalus salicinus sp. n., previously misinterpreted as R. quinquecostatus, is described and illustrated. Oscillograms of male calling signals with data on host plants and distribution of the new species that is closely related to R. artemisiae (Becker 1865) are provided. A neotype of R. artemisiae is designated. R. salicinus sp. n. and R. artemisiae are similar both in external morphology and male genitalic structure, but differ distinctly by male calling signal patterns and host plants, thus being two different biological species. The distribution of R. salicinus sp. n. covers southern European Russia, Kazakhstan and, apparently, the southern part of Western Europe. R. artemisiae is known so far only from the Lower Volga region and western Kazakhstan.
Different types of marking behavior observed in the wild during the breeding period of the common hamster (Cricetus cricetus, cricetidae, rodentia)
Authors: Kupriyanov V. P. , Surov A. V.
Published: September 2024

The marking behavior of the common hamster, Cricetus cricetus in the wild was recorded using camera traps and handheld video in the N.I. Bagrov Botanical Garden, Simferopol, Crimea. We described the following types of scent marking: with flank glands (in particular, compass-like movements in the grass and rubbing on a stone), midventral gland marking, etc. The variety of marking behavior types on different substrates may contribute to a more efficient use of olfactory signals in maintaining the social structure of the common hamster, which is notably important at high population densities in urban areas.

Dahl’s jird, Meriones dahli, is a critically endangered species restricted to a small area in central Transcaucasia. The phylogenetic position of Dahl’s jird within the Midday jird species complex was assessed based on the DNA of museum material. Both mitochondrial and nuclear gene sequences were employed. Dahl’s jird has been found to be a sister group close to M. penicilliger, which is distributed in Turan. This result suggests the existence of a late Middle Pleistocene dispersal corridor for psammophilic species that is known to have connected the Transcaucasian and Transcaspian regions.

Integro-differential diffusion equations on graded Lie groups
Authors: Restrepo Joel E. , Ruzhansky Michael , Torebek Berikbol T.
Published: September 2024

We first study the existence, uniqueness and well-posedness of a general class of integro-differential diffusion equation on L p ( G ) ( 1 < p < + ∞, G is a graded Lie group). We show the explicit solution of the considered equation. The equation involves a nonlocal in time operator (with a general kernel) and a positive Rockland operator acting on G. Also, we provide L p ( G ) − L q ( G ) ( 1 < p ⩽ 2 ⩽ q < + ∞) norm estimates and time decay rate for the solutions. In fact, by using some contemporary results, one can translate the latter regularity problem to the study of boundedness of its propagator which strongly depends on the traces of the spectral projections of the Rockland operator. Moreover, in many cases, we can obtain time asymptotic decay for the solutions which depends intrinsically on the considered kernel. As a complement, we give some norm estimates for the solutions in terms of a homogeneous Sobolev space in L 2 ( G ) that involves the Rockland operator. We also give a counterpart of our results in the setting of compact Lie groups. Illustrative examples are also given.
Acupuncture navigation method integrated with augmented reality
Authors: Chiou Shin-Yan , He Meng-Ru
Published: September 2024

BACKGROUND: Acupuncture and moxibustion are effective in alleviating symptoms, but the large number of acupoints can make accurate needle placement and training difficult. OBJECTIVE: To address these challenges, this study aims to develop an augmented reality (AR) acupuncture navigation system designed to improve the accuracy and intuitiveness of acupoint localization. METHODS: The proposed system employs a six-point registration and positioning technique, enabling the AR navigation model to adapt to the specific characteristics of each patient. RESULTS: In testing, discrepancies between virtual and actual acupuncture points ranged from 0.6 mm to 3.9 mm, which is within the acceptable tolerance range for acupuncture. CONCLUSION: This AR-based system shows promise in enhancing the precision of acupuncture point localization, potentially leading to improved treatment outcomes.
Work should not be killing us: Understanding the racial battle fatigue minefield for black women in higher education
Authors: Chancellor Renate L.
Published: September 2024

Racial Battle Fatigue (RBF) has been operationalized as the cumulative psychological, physiological, and behavioral effects of racial aggressions on individuals from marginalized groups. These micro-level and macro-level aggressions have been the focus of discussion and debate at historically white colleges and universities since the 1960s when equity in higher education became a national priority because of the civil rights movement and the introduction of Critical Race Theory (CRT). Faculty teaching in Library and Information Science (LIS) programs are not exempt from RBF. In fact, there have been several testimonials of bias and racism by LIS faculty who represent marginalized populations in recent years. Research on RBF, particularly during this current politically charged climate of hate and bias adds to our understanding of the ways in which racism, in various forms, affects Black women faculty. Applying CRT, RBF, and Black feminist theoretical frameworks, the purpose of this paper is to provide a follow up to “Racial Battle Fatigue: The unspoken burden of Black women faculty in LIS” which was published in the Journal of Education for Library and Information Science in 2019. It helps us to further understand the experiences of Black women faculty in higher education.
Learning settler colonialism in my K-12 education: A re-search counterstory
Authors: Zou Isabella
Published: September 2024

In this essay, I examine how settler colonialism operates in the dominant U.S. K-12 education system through an analysis of my own educational experiences in the Eanes School District in Austin, Texas. Grounded in the analytical frameworks of critical race theory and TribalCrit, the methodology of counterstory (telling marginalized stories in critique of dominant narratives), and my positionality as a second-generation Chinese-American settler, the paper examines how my K-12 education taught me the ideologies that underpin Indigenous dispossession and further settler colonialism’s “logic of elimination.” I re-search my experiences, from a kindergarten lesson on “Indian drums” to high school textbook readings, to trace how educational practices and curricula reinforce settler colonial ideologies and conscript students into settler society. In conclusion, I discuss decolonial teaching and how it gives students tools to recognize and challenge settler colonial ideologies.
Rapid simulation method for assessing seismic damage to building curtain walls on a regional scale using designed wind load capacity

This study introduces a rapid simulation method for assessing seismic damage to building curtain walls at a regional scale. Although the results are approximate, this approach enables quick evaluations, making it an important instrument for emergency responses during disaster situations. This method’s independence from numerical models is a noteworthy advantage. Unlike conventional approaches, it eliminates the need for structural analysis models when evaluating the seismic capacities of curtain walls regionally. Creating reliable structural analysis models is both time-consuming and labor-intensive, primarily due to the detailed design information they require. In contrast, the presented method leverages the wind load capacities for which curtain walls are designed. It is based on the core premise that most curtain walls, primarily designed for wind resistance, possess wind load capacities that could serve as substitutes for their seismic capacities, even if they are not explicitly designed for such seismic loads. To assess the method’s effectiveness, it was applied to seismic damage assessments across regions experiencing varying wind intensities: weak, moderate, and strong. The results suggest the likelihood of curtain walls sustaining seismic damage in regions with weak wind could be five times higher than in regions with strong wind. This underscores the importance of seismic design considerations for curtain walls. Moreover, the findings closely match the actual seismic damage assessment data from a region with a moderate to strong wind intensity.
