Published: December 2022

Запропоновано механізм моніторингу формування екологічної небезпеки в умовах дії фізичних чинників. Проведено  аналіз наукових праць, присвячених дослідженню способів та методів зниження рівня природно-техногенного навантаження на довкілля та окремі його компоненти.
Установлено діапазони функціонування екологічної небезпеки в соціально-економічній зоні: фонова небезпека, небезпека незначного рівня, прийнятна небезпека, неприйнятна небезпека, катастрофічна небезпека.
Розглянуто види стійкості стану соціально-економічної зони за умов рівноваги, гомеостазу та стаціонарного режиму.
Побудовано модель деформації стану екологічної безпеки під впливом фізичних та інших антропогенних чинників, яка грунується на розв’язанні трьох окремих завдань: аналізу функціонування екологічної небезпеки за наявності сукупності її складових різного генезису; поліпшення стану екологічної безпеки в умовах комплексного впливу її джерел; формування елементів забезпечення  екологічної безпеки в природно-антропогенних водоймах. Вона включає систему з чотирьох аналітичних залежностей (опис можливості переходу соціально-економічної зони з одного в інший стаціонарний стан відповідно до характеристики та рівня впливу антропогенних чинників; характеристику стану забруднення водної складової екосистеми залежно від потужності джерела забруднення та особливостей біфуркації; опис зміни у часі екологічного ризику впливу фізичних чинників; визначення комбінованої умови варіаційного розв’язання окремих завдань щодо якості системи управління екологічними проектами) та граничні умов її існування.
Результати дослідження свідчать, що використання моделі деформації стану екологічної безпеки під впливом фізичних та інших антропогенних чинників дає можливість розробити та реалізувати виважені рішення з управління екологічними проектами.
КОАГУЛЯЦІЯ І ДИСПЕРГУВАННЯ В ПОЛІДИСПЕРСНИХ РІДКИХ АЕРОЗОЛЯХ В РЕЗУЛЬТАТІ ЗОВНІШНЬОЇ АЕРОДИНАМІЧНОЇ ДІЇ
Authors: Кравець Василь Анатольович
Published: December 2022

У полідисперсних рідких аерозолях (туманах) в результаті зовнішньої аеродинамічної діїможуть відбуватися процеси коагуляції і диспергування крапель. Ці процеси впливають навеличину загальної поверхні крапель полідисперсного аерозолю, що, в свою чергу, впливає натривалість осідання аерозолю, інтенсивність випаровування та розповсюдження. Це має великепрактичне значення для оцінки поведінки аерозольних хмар, що утворилися в результаті вибуху,механічного дроблення при падінні рідини з великої висоти, або коли рідина роздуваєтьсяпотоком газу. Такі ситуації характерні для техногенних катастроф, розпилюванні інсектицидів тагербіцидів за допомогою авіації або при використанні хімічних засобів ведення війни.Встановлено, що характер процесів визначається швидкістю газу відносно крапельполідисперсного аерозолю. Існує критична швидкість газу, яка визначає напрям процесів зміненнязагальної поверхні полідисперсного аерозолю. За швидкістю, менш критичної, відбуваєтьсяпроцес зіткнення краплин різного діаметру і йдуть процеси коагуляції, в результаті чого загальнаплоща поверхні аерозолю зменшується. При швидкостях, що перевищують критичну швидкість,паралельно з коагуляцією починається процес роздрібнення крапель, що приводить до збільшенняплощі поверхні аерозолю. Теоретичним шляхом, на основі рівнянь енергетичного балансу,отримана математична залежність відносної поверхні аерозолю від відношення швидкості газу докритичної швидкості. Ця залежність має характер квадратичної функції. Величина критичноїшвидкості залежить від критичного значення критерію Вебера (We). Для аерозолів механічногопоходження рекомендовано приймати критичне значення критерію Вебера Weкр=1,3. Отриманазалежність була використана при розробці технології подавлення бурого диму газоподібнимазотом при переливах чавуну на підприємствах чорної металургії.

Published: December 2022

The Covid-19 pandemic has been responded to various attitudes and behaviors related to its prevention. Understanding certain information makes a person make the right decision. Misunderstanding the improvement of the immunity system and prevention of COVID-19 may lead to inappropriate attitudes and behaviors in using supplements in society. This study aims to describe the level of knowledge and attitudes toward using health supplements and the consumption of health supplements during the Covid-19 pandemic. The research design is a cross-sectional study using primary data based on data collection by questionnaire. The research subjects were visitors of Jamsaren and Riyadh pharmacies in September 2020 who were more than 17 years old, could read and write, and were willing to be respondents. Knowledge is assessed by each correct answer marked 1, and then the total is compared with the total score multiplied by 100%. The level of knowledge is classified based on the score obtained; poor knowledge (score <70) and good (>70). Attitudes are classified into panic and non-panic. Behavior was analyzed descriptively. The results on 132 subjects showed that most of the respondents (78%) still had less knowledge of using health supplements to prevent Covid-19. The Chi-Square test results obtained a p-value of 0.312 (p > 0.05), meaning no significant difference in knowledgeable or good knowledge in respondents' responses. The attitude variable affects the respondent's behavior, as evidenced by the p-value of 0.008 (p <0.05). The predominant health supplement is vitamin C from pharmacies on their initiative
Introduction: World Fairs, Exhibitions and Anthropology
Authors: Ferraz de Matos Patrícia , Birkalan-Gedik Hande , Barrera-González Andrés , Vail Pegi
Published: December 2022

World fairs and exhibitions served as important venues for empires to showcase their industrial and technological achievements. Moreover, they also presented ‘civilisational models’ that portrayed Europeans as the most advanced and sophisticated and depicted the distant inhabitants as exotic and primitive. In portraying distant peoples, these contrasts were evident through their dress styles, dance, music, and performance of daily customs, but most noticeably, through their skin colours. With five articles focusing on world fairs and exhibitions in diverse locations and times, this special issue raises questions about the display and showcasing of humans that are still pertinent to the current contexts of anthropology. The articles call for ‘decolonising’ thoughts, discourses, and practices in political and public space in displaying contemporary cultures. While acknowledging the problematics and limits of ‘decolonisation’ itself, the articles reassess through a critical lens the connections between fairs and exhibitions in the early days of anthropology.
The Mise-en-Scène of Modernity
Authors: Freeman Nicolas
Published: December 2022

This article examines the various stagings of progress as exhibited at Argentina's International Centennial Exhibitions hosted in Buenos Aires in 1910. In preparation for the exhibitions, a wealthy port aristocracy oversaw renovations of the private and public, material and symbolic spaces of the city which transformed the capital into a political theatre. A chronology of the exhibitions (agriculture, industry, hygiene, railways, and the arts) and their accumulated symbols are read as multidimensional sites of encounter where a clash of contradictory interests and agencies interact. The text emerges out of a moment of ethnographic encounter and weaves together the words of my interlocutors with historical and theoretical analysis. In doing so, the article reflects from different angles upon the relationship between the rituals of showing and of spectatorship involved in the State's aesthetic performance of national progress.

Published: December 2022

Minas Gerais é o maior produtor nacional de queijo artesanal, oriundo de sete regiões produtoras (Serro, Canastra, Araxá, Campo das Vertentes, Serra do Salitre, Cerrado e Triângulo Mineiro). Embora estas regiões possuam em comum a forma de obtenção deste produto a partir do leite cru, cada região produz queijo com identidade própria devido às condições climáticas, o preparo artesanal e principalmente quanto ao período de maturação, que exerce um impacto direto nas suas características físicas e na aceitação pelo consumidor. A Portaria n°1305 de 2013 prevê para a comercialização do queijo Minas Artesanal da microrregião do Cerrado o período de maturação de 22 dias, considerando que este período pode ser modificado perante a realização de novas pesquisas que ratifiquem ou retifiquem o tempo atual de maturação. Este trabalho avaliou a evolução da umidade, cor e textura instrumentais em queijo Minas Artesanal do Cerrado Mineiro durante a maturação (0, 7, 10, 14 e 22 dias) em período chuvoso. As amostras de queijo foram coletadas diretamente com os produtores e encaminhadas para as análises de umidade até massa constante a 105 °C e a cor instrumental (luminosidade (L*) e as coordenadas de cromaticidade a* e b*). A textura foi quantificada através da força de cisalhamento e expressa como dureza (N). A umidade reduziu nas amostras de queijo (50,28 % para 36,1 %), o que evidencia a perda de água esperada durante o período. No 7º dia de maturação, os queijos atingiram 42,15 % de umidade, média dentro do intervalo de umidade adequado (36 a 45,9%) para o consumo seguro, estabelecido pela Resolução n° 7, de 28/11/2000 do MAPA. Houve redução significativa de (L*= 55,78 a 46,27), que demonstra o escurecimento dos queijos, uma das consequências da maturação. A coordenada de cromaticidade a* (a*= - 1,38 a -1,94) demonstrou tendência à coloração verde. Conforme esperado, a coordenada b* (b*= 9,29 a 12,55) indicou a tendência à cor amarela de forma crescente no período. O aumento da mudança global de cor (E) (6,69 a 10,74) e da dureza (10,42 N a 26,52 N) foram significativas e podem ser correlacionadas com o teor de água perdido no produto durante a maturação, sendo parâmetros viáveis de serem quantificados e úteis no monitoramento nas características sensoriais e visuais dos queijos, contribuindo para a caracterização do queijo Minas Artesanal do Cerrado quanto ao período ideal de maturação e sua posterior regulamentação.

Four macroalgae species, three red algae (Palmaria palmata, Gracilaria gracilis and Porphyra umbilicalis) and one green algae (Ulva rigida) were analysed to calculate and compare their proximate composition. These algae were grown in aquaculture in the same geography, and were also harvested in the same season. Ulva rigida differentiates the most from the other with higher contents of carotenoids and lower content in ashes. Palmaria palmata shows the lower contents in total sugars, lipids, and protein, but higher in ashes. Porphyra umbilicalis and Gracilaria gracilis have similar contents showing high contents of both lipids and protein. Keywords: Seaweeds, Algae, Portuguese shore, Chemical composition of seaweeds.
EFICIÊNCIA DO MÉTODO DE CENTRIFUGAÇÃO ASSOCIADO À SECAGEM EM ESTUFA NA DETERMINAÇÃO DA CAPACIDADE DE RETENÇÃO DE ÁGUA DE DIFERENTES CORTES CÁRNEOS

A capacidade de retenção de água (CRA) é um dos parâmetros tecnológicos mais importante da carne, uma vez que pode influenciar a aparência do produto, seu processamento e a sensação de suculência durante a mastigação. Portanto, é de extrema importância a condução de estudos que desenvolvam e validem metodologias simples e eficientes para analisar a CRA de diferentes cortes cárneos na indústria. Diante do exposto, o objetivo desse estudo foi avaliar a eficiência do uso do método de centrifugação associado à secagem em estufa na determinação da CRA do contrafilé bovino, lombo suíno e peito de frango. Os cortes foram coletados em frigorífico comercial e as analisados no Laboratório de Análise de Alimentos de Origem Animal da Universidade Estadual Paulista, campus de Jaboticabal. O delineamento experimental utilizado foi o inteiramente casualizado, com 20 repetições/corte. Amostras de 1g foram embaladas em papel filtro e submetidas à centrifugação a 1500 rpm durante 4 minutos. Posteriormente, metade das amostras foram levadas à estufa a 70ºC por 12h (tratamento controle) e a outra metade por 6h (tratamento alternativo). A CRA foi calculada pela diferença entre o peso inicial e o peso final, dividido pelo peso inicial e multiplicado por 100. Os dados foram submetidos à análise de variância pelo procedimento GLM do SAS e as diferenças entre as médias foram testadas por teste de Tukey, com nível de significância de 5%. Verificou-se que não houve diferença significativa entre os resultados de CRA obtidos pelo método de centrifugação associado aos diferentes tempos de secagem em estufa para quaisquer dos tipos de carne avaliados, com média de 35,1%, 31,2% e 29,1% para os cortes bovino, suíno e de frango, respectivamente; demonstrando a otimização do tempo, de 12h para 6h, na realização das análises. Entretanto, os resultados encontrados estão muito aquém daqueles reportados na literatura, quando empregado o método de pressão tradicionalmente usado para esta análise, o que demonstra necessidade de futuras adequações à metodologia aplicada no presente ensaio. Estas diferenças podem estar associadas à combinação dos efeitos da centrifugação e da secagem em estufa sobre a CRA, uma vez que tais processos podem levar a uma maior retração do tecido muscular, desnaturação das proteínas miofibrilares e consequente elevação na perda de água. Conclui-se, portanto, que o método de avaliação da CRA por centrifugação associada à secagem em estufa não demonstrou eficiência necessária para que seja empregado com sucesso na indústria.

Published: December 2022

A kombucha é uma bebida levemente doce, e teve sua origem no Oriente, no entanto ganhou popularidade no Ocidente, devido aos seus efeitos terapêuticos. Devido ao potencial tecnológico e inovador dessa bebidas, ainda pouco explorada e a falta de trabalhos relacionada a ela, faz-se necessária a busca por informações relacionados ao potencial tecnológico e funcional da Kombucha. Por meios de estudos foi possivel analisar o estado da arte e quais usos estão sendo feitos dessa bebida e seus subprodutos e o crescimento futuro. Desta forma, este trabalho propôs realizar um mapeamento de documentos sobre a aplicação da kombucha, e assim, apresentar uma visão geral a respeito do desenvolvimento tecnológico e científico relacionado ao seu uso. O estudo foi realizado no sait de Dados do Instituto Nacional de Propriedade Industrial do Brasil (INPI), United States and Trademark Office (USPTO) e European Patent Office (ESPACENET). Após a busca, os resultados foram processados e analisado. Assim, buscamos documentos de existentes nas bases de dados através de uma busca avançada utilizando os termos: “kombucha”, “kombucha and product” e “kombucha and drink”. Foi observado uma quantidade bem reduzida de documentos existente nas bases do INPI e USPTO, encontrando apenas 6 resultados. Entretanto no sait de dados ESPACENET foram encontradas 1444 patentes nos últimos 10 anos. No contexto brasileiro, a kombucha vem ganhando destaque no mercado, embora com poucos depósitos de trabalhos. Entretanto, ressaltamos que embora a kombucha seja uma bebida milenar, ainda é pouco explorada em termos de inovação científica e aspectos funcionais.

Published: December 2022

O uso de frutas tropicais na produção de bebidas fermentadas é interessante como forma de agregar valor a frutos regionais e como meio de continuidade de vendas fora da sazonalidade. A união do Sapoti e do Cajá-Umbu traz ao fermentado originalidade e regionalidade, pois o Nordeste se destaca como polo produtor dos frutos. O cajá-umbu (Spondias mombin l.), é um fruto proveniente de regiões semiáridas e litorâneas que apresenta casca fina e lisa, coloração amarelada e presença de endocarpo com possibilidade de uso na sua forma processada. Já o Sapoti, é um fruto suculento com aroma e sabor agradável, características sensoriais com ótima aceitação, que favorece seu aproveitamento de forma industrial para produção de diversos produtos. A funcionalidade da bebida fermentada adicionada desses frutos está relacionada à capacidade dos frutos, após processo de fermentação, manterem suas características funcionais e compostos que os tornam nutritivos. O processamento de frutas permite prolongar a vida útil das mesmas, trazendo ao consumidor praticidade e facilidade, uma vez que frutos amadurecem e perdem qualidade, pós-colheita. Para elaboração do fermentado de frutas, os insumos foram adquiridos em comércio local de Fortaleza-CE e desenvolvido no Laboratório de Frutos e Hortaliças da UFC. Os frutos foram higienizados, despolpados, triturados. Em seguida a levedura S. cerevisae foi inoculada, e o mosto foi submetido à fermentação. O período de fermentação durou 3 dias à temperatura ambiente, considerada ótima para a levedura utilizada. Ao final do período, a trasfega foi feita para recipiente de vidro medindo teor de sólidos solúveis, com o auxílio do refratômetro digital, obtendo 6,5 °Brix. Foram desenvolvidas as fichas técnicas e de custo da bebida. O produto se mostrou com bom rendimento (86,5%), com um custo médio de R$ 13,50/Litro. A fermentação do fruto de sapoti junto com o de cajá mostrou ser viável e apresentou boas características sensoriais, mantendo o aroma e sabor particular dos frutos.

Authors: Singh Ripu , Shrestha Sajeev , Acharya Pujan , Shrestha Ashish
Published: December 2022

Ameloblastoma is an uncommon benign epithelial neoplasm of odontogenic origin that accounts for about 18% of the odontogenic tumour. It is a slow-growing, locally invasive but rarely metastatic tumour. Extraosseously occurring peripheral ameloblastoma is a rare variant that comprises about 2-10% of all ameloblastoma. We report a case of peripheral ameloblastoma in a 43-years old male patient affecting the mandibular canine-premolar region with a histopathological diagnosis of acanthomatous ameloblastoma. This case report emphasises the clinical, radiographic, and histological features of a rare variant that distinguishes it from the other similar appearing lesion on gingiva along with its various treatment modalities.

Authors: Thakur Dipak Kumar , Agrawal Chandra Sekhar
Published: December 2022

Introduction: Retrograde intra-renal surgery using flexible scopes and laser energy is a newer alternative in stone disease treatment armamentarium. It is claimed to be superior to other modalities for stone clearance, complications and hospital stay. The aim of this study was to find out the prevalence of complete stone clearance after retrograde intra-renal surgery among patients with urolithiasis in a tertiary care centre.
Methods: This was a descriptive cross-sectional study conducted in the Department of Urology in a tertiary care centre from 15 June 2021 to 14 May 2022 including adult patients with stone size up to 15 mm. Ethical approval was obtained from the Institutional Review Committee (Reference number: IRC-PA-143/2077-78). Convenience sampling was done. The prevalence of complete stone clearance (no residual fragment >4 mm) was calculated. Point estimation and 95% confidence interval were calculated.
Results: Among 42 patients, 36 (85.71%) patients (75.1-96.3, 95% Confidence Interval) achieved complete stone clearance. The mean age was 40.26±14.05 (16-74) years and the stone size was 1.27±0.19 (0.9 -1.5) cm. Similarly, the mean operating time was 51.55±9.34 (40-85) minutes and the hospital stay was 1.33±0.52 (1-3) days. Grade 3 ureteric injury occurred in one case. Residual fragments were seen in 6 cases (14.29%). Sepsis occurred in 4 cases (11.11%).
Conclusions: The prevalence of complete stone clearance was similar among patients undergoing retrograde intra-renal surgery in our study when compared to other studies conducted in similar settings.

Published: December 2022

Introduction: Micronucleus is used as a biomarker of chromosomal instability, which is one of the hallmarks of neoplastic transformation. As micronuclei score increases with malignancy, it can be an effective and inexpensive adjunct to breast fine needle aspiration cytology, in diagnosing breast lumps, especially detecting grey lesions between benign and malignant tumours. The aim of this study is to find out the mean micronuclei score in fine-needle aspiration cytology of patients with malignant breast lumps in the Department of Pathology in a tertiary care centre.
Methods: A descriptive cross-sectional study was conducted among patients with malignant breast lumps in the Department of Pathology in a tertiary care centre between 1 May 2020 to 31 May 2021 after receiving ethical approval from the Institutional Review Committee (Reference number: IRC/2139/021). The fine-needle aspiration cytology of breast lumps was diagnosed as per National Health services breast screening program guidelines. The mean micronuclei score was calculated. Convenience sampling was done and data were collected from the hospital records in the Department. Point estimate and 95% Confidence Interval were calculated.
Results: Among 20 malignant breast aspirates, the mean micronuclei score was found to be 8.30±3.75 (3-19, 95% Confidence Interval).
Conclusions: The mean micronuclei score in fine-needle aspiration cytology of malignant breast lumps was found to be similar when compared to similar studies conducted in similar settings.

The African flank of the Great Indo-Pacific Areal: Strategic significance and associated challenges
Authors: Fituni Leonid L.
Published: December 2022

The “West to East shift” in the dynamics of global development and in defining trends of the world order restructuring goes hand in hand with a synchronous rearrangement of the balances of geopolitical and geoeconomic power from the Euro-Atlantic to the Indo-Pacific area. Those phenomena comply with the more general dialectical laws of the contemporary world development, one set of which relates, in particular, to the interconnection between the processes of globalization and regionalization, on the one hand, and the uneven development of states, on the other. In that context, the author proposes a concept that considers the Great Indo-Pacific Area (BITA) as a megazone that determines the near future of world dynamics. Unlike other proposed constructs of late under consideration, BITA encompasses all coastal states. It is neither limited nor divided by various alliances or geostrategic designs of the leading powers. The evolving post-globalization process of regionalization does not contradict the formation of BITA but, on the contrary, according to the author, constitutes a factor that ensures its long-term sustainability. The state and significance of the Western (African) flank of the BITA has so far been out of the focus of research attention. The author fills this gap by analyzing the system-forming factors of the subregion, its potential, geostrategic significance and the regional maritime strategies of the leading powers in it.

Age-related macular degeneration (AMD) is the main cause of central vision loss in elder group of patients. At the same time, annually, the number of people with detected changes in the retina corresponding to different forms of macular dystrophy is steadily growing. The disease is considered to be a highly significant medical, social and economic problem, since a deterioration of the central vision negatively affects the life quality and work capacity of patients. The article presents an analysis of modern views concerning the current therapy possibilities for the dry form of AMD, including the use of nutraceuticals, consisting of lutein, zeaxanthin, mesoseaxanthin, as well as an overview of the directions of development and clinical trials. The use of lutein- and zeaxanthin-containing compounds can be recommended for prevention both the AMD progression and the presence of risk factors for its development, especially in persons over 50 years of age, as well as in the presence of high visual workload.
