Transformation of the nickel aluminide alloy structure through the application of a heat-resistant coating using oscillation electrode surfacing
Authors: Zorin I. V. , Lysak V. I. , Kharlamov V. O. , Fastov S. A. 
Published: January 2024

This study considers the formation of an alloyed nickel aluminide structure through automatic electric arc surfacing employing an oscillating electrode composed of composite wire. The arc transversely traverses the weld pool surface at a frequency denoted as f. In comparison to conventional surfacing techniques, this process either displaces the crystallization front alongside the weld pool (at f  = 1.3 Hz) or stabilizes it (at f  ≥ 2 Hz) throughout the cross-sectional area of the coating layer. We have conducted an investigation into the evolution of alloy structures resulting from surfacing. Notably, we have observed that the regions with concentrations of eutectic nickel-aluminum are particularly susceptible to structural alterations. The formation of particle clusters, which is contingent upon heat dissipation conditions near the crystallization front, leads to the development of layered texture regions. Our findings reveal that following 50 thermal cycles (heating to 1100 °C, cooling to 25 °C), the alloy's hardness becomes independent of subsequent thermal cycles, consistently maintaining a level 34–35 HRC. The highest resistance of the surfaced metal to thermal fatigue cracks is achieved when its structure exhibits an optimal γ-solid solution (relatively ductile) to nickel-aluminum cooling martensite ratio, corresponding to the Ni2Al phase. The thermal conditions necessary for producing such a structure are elucidated by the gradual cooling of the crystallized metal from elevated temperatures when f  ≥ 2.8 Hz. An analysis of changes in oxidative wear, estimated by mass loss, during thermal fatigue tests conducted at a metal heating temperature of 1100 °C revealed the superiority of the studied alloy over industrial alloys based on nickel and cobalt.

Authors: Martín Guillermo 
Published: January 2024

La estrategia de resguardar el 30% de la superficie del planeta en áreas protegidas (AP) ha encontrado consenso mundial en el marco del Convenio sobre la Diversidad Biológica (CBD), bajo la expectativa de proteger la biodiversidad y, simultáneamente, atender problemas tradicionales como la distribución de la riqueza. ¿Qué medidas y modelos permitirían satisfacer lo esperado y hasta qué límite? Para encontrar respuestas, este estudio explora múltiples opiniones recogidas mediante búsqueda bibliográfica, entrevistas y recorridos por el campo, con el objetivo de exponer casos seleccionados por ser ejemplos de complejidades, contradicciones y desafíos. Se concluye que proteger la biodiversidad y, a la vez, lograr mejoras sociales es una meta deseable, a la que no se llega fácilmente ni por cualquier camino, porque las AP proporcionan potentes oportunidades para mejorar la vida humana sólo si se gestionan dentro de su matriz de inserción territorial, atendiendo a equilibrios inestables, modelos multivariables particularizados y lúcidas estrategias adaptativas.
From tradition to transformation: The journey of school librarianship in India
Authors: George Sigy 
Published: January 2024

This article delves into the rich tapestry of school librarianship in India, spanning from its ancient origins to its contemporary state. The study employs a multidisciplinary approach, combining historical analysis, cultural insights, and educational perspectives to unravel the nuanced development of school libraries and the roles of librarians within them.Beginning with the ancient Indian tradition of Gurukuls, where oral transmission of knowledge was paramount, one can trace the evolution of early libraries and the revered "Guru-Pustakalaya" (teacher's library) as the precursor to formal school libraries. The medieval era witnessed the advent of Persian and Arabic manuscripts, leading to the establishment of Madrasas and Maktab libraries, which contributed to the dissemination of diverse knowledge. The colonial period introduced Western educational ideals and the establishment of missionary schools, thereby reshaping the landscape of school librarianship with the introduction of modern library systems and practices.In the post-independence era, the Indian government took significant steps to promote literacy and education, resulting in the proliferation of school libraries across the nation. The article explores the transformative impact of technology, the digital age, and the changing role of school librarians as facilitators of information literacy and digital resources. This comprehensive historical analysis sheds light on the continuum of school librarianship in India, emphasizing its pivotal role in education and knowledge dissemination throughout the ages. Understanding this evolution is essential for shaping the future of school libraries and librarianship in India, adapting to the changing educational landscape and information needs of the 21st century.

Libraries have a history dating back centuries, serving as guardians of knowledge and fostering intellectual growth. Libraries have long been a cornerstone of human civilization, serving as repositories of knowledge, cultural hubs, and learning centers. However, in the age of artificial intelligence (AI), some have questioned the relevance of libraries. This article explores the timeless relevance of libraries in an era marked by rapid technological advancements. The article uses a qualitative method and draws on a review of academic articles, studies, and case studies about libraries, artificial intelligence (AI), and digitalization. The analysis focuses on the historical importance of libraries, the challenges they confront in the age of AI, and prospective approaches to incorporating AI into library services. Libraries play a vital role in fostering these skills, offering a range of resources and educational programs to help individuals navigate the digital landscape effectively. Librarians, with their expertise, guide users in assessing the credibility of online sources, understanding data privacy, and developing information literacy skills. By promoting digital literacy, libraries empower individuals to make informed decisions in the age of AI, mitigating the risks associated with misinformation and algorithmic biases. Libraries remain relevant and essential in our society. Beyond their role as knowledge repositories, libraries promote critical thinking, digital literacy, community engagement, and equitable access to information. As we navigate the complexities of the digital age, libraries continue to serve as intellectual and social sanctuaries, fostering human connections and preserving the values that make us uniquely human.

Published: January 2024

The management of the resorbed mandibular ridge is a difficult task. Rehabilitating a patient who is completely edentulous is a common dental procedure, but it can sometimes be challenging and difficult. Making an impression with the available stock trays, even after modification, is difficult in extremely resorbed ridges.Many materials have been used to record and transfer the neutral zone in complete dentures. So here we present a new technique of making an impression with properly adapted wire for recording the impression along with recording the neutral zone with a heavy body addition silicone impression material that rests on the wire loops projecting upward on the denture base to achieve maximum retention and stability and also for the preservation of residual alveolar ridge.
American public opinion on NATO, the Russian-Ukrainian conflict
Authors: Popov Nikolay 
Published: January 2024

There is a large faction among American population that supports Ukraine in its conflict with Russia and approves of the United States providing assistance to it, among other things, long-term military assistance. Public opinion polls before the start of Russia&apos;s special military operation in Ukraine, during the operation and during the NATO summit in Vilnius showed a steady public demand for strengthening the role of America as a world leader, the involvement of the United States in international affairs and support for Ukraine in the armed conflict with the Russian Federation. After a long period of criticism by the Americans of &quot;excessive US involvement in European affairs”, in particular in NATO, the conflict in Ukraine caused an increase in US support for NATO, the inclusion of new members in the alliance – Finland and Sweden, active NATO military assistance to Ukraine, a course for its accession to NATO.
The population expresses significant support for its actions in the fight against Russia, extensive and long-term assistance to Ukraine from the United States. Attitudes towards the conflict in Ukraine and the role of NATO differ significantly among supporters of the Democratic and Republican parties – Democrats have more support and Republicans have less. The topic of the Russian-Ukrainian conflict will undoubtedly be raised during the election campaign for the 2024 elections.
New Directions for Canadian Cultural Policy
Authors: Shchukina Tatiana 
Published: January 2024

Over the last two years of the pandemic, the arts, culture and heritage sectors have experienced unique challenges. These sectors have been amongst those hit hardest and longest by the COVID-19 pandemic. This has not only affected their economic viability but also their relationship with the public, whose interests, expectations, access and behaviours have shifted dramatically over the last two years. The pandemic accelerated a shift already underway in Canadian society. Polarization, disinformation, an unequal set of rules for the foreign online broadcasters and social media companies challenge social cohesion in Canada. This reality, combined with growing awareness of systemic racism and a greater acceptance of the need to confront the climate crisis have created a need to reimagine policies, principles, and practices to ensure continued long-term, sustainable growth, competitiveness, and vitality of the arts, culture, and heritage sectors in Canada.
Canada’s arts, culture and heritage sectors play a fundamental role in building a stronger, more cohesive and resilient society. These sectors are not only significant economic drivers but they also contribute to Canada’s identity and social fabric. They help Canadians create meaning and forge a stronger shared identity based on shared values. However, to achieve these beneficial effects, there needs to be a renewed and shared understanding of these sectors’ fundamental roles and value. The Government of Canada convened the National Culture Summit: The Future of Arts, Culture and Heritage in Canada to help these sectors recover and thrive as well as mobilized these sectors around positive economic and social outcomes for Canada and discussed ways to support their own recovery and long-term growth and competitiveness. The Summit brought together leaders from across the country from these sectors for a national conversation on resilience, sustainability and transformation of the arts, culture and heritage sectors in Canada.
The summit’s four themes were:
•Promoting long-term competitiveness and growth;
•The return of visitors and engaging new audiences;
•The role of digital platforms in arts, culture and heritage sectors; and
•The contribution of cultural sectors to reconciliation, combatting climate change and building an open and more inclusive society.

Pursose. Our purpose was to evaluate less well known factors and outcome associated to bleeding in STEMI patients after primary PCI and concomitant antithrombotic therapy during Covid-19 pandemic.
Methods. This was a retrospective, observational study of the prevalence and factors associated to hospital bleeding in 317 STEMI patients (74.8% men, mean age 65.7±11.9 years) and of the impact of bleeding on 30-day and 6-month survival in STEMI patients during the Covid-19 pandemic from January-October 2021. The leading reperfusion strategy was primary PCI; we registered all significant bleeding events.
Results: Concomittant Covid-19 was observed in 3.2% of STEMI patients. Primary PCI was performed in 94.3% of all cases, but only in 17% within the first 3 hours of chest pain. Bleeding was observed in 11.4% of all STEMI patients and was associated significantly with out-of-hospital cardiac arrests (OHCA), hospital complications and mortality. In bleeding and nonbleeding patients the prevalence of age, sex, comorbidities, Covid-19 cases, the use and start of primary PCI was similar.
Conclusions: The prevalence of hospital bleeding in treatment of STEMI patients during Covid-19 pandemic was 11.4% and was associated significantly to OHCA, hospital complications and early mortality of STEMI patients.

Published: January 2024

Purpose: This study presents a rare skin manifestation of Lyme borreliosis, specifically affecting the areola in a child in the absence of a history of a tick bite or erythema migrans.
Case report: A 9-year-old boy presented with symptomless erythematous swelling of the breast areola for one month. Initial treatment for gynecomastia and then mastitis proved ineffective. A biopsy was performed, with histological findings revealing lymphocytoma, likely stemming from an insect bite. Serology for Borrelia burgdorferi was positive. Following a two-week course of oral amoxicillin, the lesion completely resolved.
Conclusion: The consideration of Lyme disease should be a component of the differential diagnosis of skin lesions localised in typical areas, particularly in patients living in endemic regions.
Myocutaneous bipedicled flap, a free tarsoconjunctival graft, and a free skin graft for reconstruction of subtotal upper lid defects
Authors: Šarenac Tomislav 
Published: January 2024

Purpose: To evaluate and present the outcomes of a single-step approach using a free tarsoconjunctival graft, a myocutaneous bipedicled flap, and a free skin graft for the reconstruction of subtotal upper eyelid defects following tumor excision.
Methods: This retrospective case series involved four patients who underwent upper eyelid reconstruction after tumor surgery. The defect affected 50%─75% and > 75% of the eyelid in two patients each. Among the latter patients, the lateral and medial canthus were involved in one patient each. The posterior lamella was reconstructed using the contralateral upper eyelid tarsoconjunctival graft, which was attached to the levator muscle at the site of the defect. The levator was weakened and elongated using small myotomies in one patient. The anterior lamella was reconstructed with a myocutaneous bipedicled flap based laterally and medially, leaving an exposed area beneath the brow, which was covered with a free skin graft.
Results: The patients had successful non-necrotizing healing and achieved satisfactory cosmetic outcomes. None of the patients developed clinically significant lagophthalmos, which would have required lubrication. Normal levator function was achieved in all patients. Two patients required additional surgery to repair pseudotrichiasis.
Conclusion: Subtotal upper eyelid defects could be effectively reconstructed using a combination of a free tarsoconjunctival graft, a bipedicled myocutaneous flap, and a free skin graft. Two-step procedures could be avoided in most cases by using this method.
“The Scream”: Using the Visual Critical Pedagogy of Subversive Indigenous Art in the Elementary Classroom to Discomfort the Comforted and Activate the Empathic, Ethical, and Relational Dimensions of Reconciliation
Authors: Brar Victor 
Published: January 2024

This paper uncovers my journey as K-12 practitioner in British Columbia towards exploring the use of “subversive art” as a “visual critical pedagogy” (Gil-Glazier,2015; Naidus,2005; Peters, 2016; Zorilla & Tisdell, 2016) to advance my students and myself towards reconciliation with Indigenous Peoples in Canada. I use the powerfully unsettling painting done by Cree artist, Kent Monkman, titled “The Scream”, as a springboard for this inquiry. “The Scream” provides an Indigenous counternarrative to the colonial versions of residential school histories and has the potential to progress practitioners and students towards actionable reconciliation by activating their empathic and ethical consciousness. I attempt in this essay to weave together a cluster of concepts, as I explore: (a) the nature and evolution of truth in BC’s elementary school curriculum (Andersen, 2017); (b) the historical establishment of the curriculum in a positivist modality (Gadamer, 2013; Greene, 1975; Marker 2004); (c) Greene’s (1995) argument that aesthetic education can help students and practitioners to engage meaningfully with difficult knowledge; (d) Greene’s (1977, 1995) philosophy of wide-awakeness, through which students and practitioners can activate the power of difficult knowledge; (e) Gadamer’s (2013) “fusion of horizons” as a means by which wide-awakeness can function in this context; (f) “subversive art” as a form of “visual critical pedagogy” (Gil-Glazer, 2015); (g) and the critical pedagogy of Paulo Freire. I braid these concepts together using the scholarship of Indigenous scholar, Michael Marker (1951-2021) to provide the pedagogical rationale for my determination to establish the visual critical pedagogy of “subversive art” in my classroom.
