Published: September 2024

The monitoring of Colorado potato beetles in large fields is a complex and time-consuming process that requires accurate data collection, analysis, and interpretation. The use of artificial intelligence (AI) can greatly simplify this complex process by automatically monitoring fields and detecting beetles marking locations of their location. We trained an object detection neural network using YOLOv5 framework using the dataset with 150 images of the Colorado potato beetles photographed in the natural conditions. We trained YOLOv5s model and got the most perfect result that was 0.995 mAP. Using the best trained neural network, we can now put videos and image files in the code and the neural network will run and detect all the Colorado potato beetles in the given files automatically.

Within the framework of the LBTU Malnava College project "The influence of growing conditions on ornamental plants", a study was conducted, the aim of which was to evaluate the influence of the sky on the growth of ornamental plants and herbs and the phenolic content of mint and lemon balm leaves when grown in an urban garden. According to the obtained results, it was concluded that the differences in phenol content are more significant only for mint and this difference can be influenced not only by the fact that the plants were grown in an urban environment, but also .by many other factors such as climate, fertilization, soil composition, precipitation, etc.
Hydraulic tests of a new centrifugal pump with shrouded impeller for extracorporeal membrane oxygenation systems
Authors: Isaeva Maria S. , Petrov Alexey I. , Banin Evgeny P.
Published: September 2024

BACKGROUND: The problem of creating a centrifugal pump for extracorporeal membrane oxygenation systems (hereinafter referred to as ECMO), optimal in terms of its hydraulic characteristics and its effect on blood, still remains relevant. This work is a continuation of the authors’ previous research in this area and contains the results of hydraulic tests of prototypes of the new ECMO pump with the closed impeller on water and water-glycerin mixtures, which imitate the viscous properties of blood.
AIM: Determination and comparison the head-flow characteristics of the new ECMO pump with the closed impeller when operating on water and water-glycerin mixtures.
METHODS: A series of hydraulic tests of pump prototypes, manufactured using different technologies, was carried out. Three liquids were considered as the working fluid during the tests: process water at a temperature of 20 °C and two water-glycerin mixtures at a temperature of 20 °C with different ratios of water and glycerin (to obtain different viscosities).
RESULTS: The pressure characteristics of pump prototypes, manufactured using different technologies, were obtained using water and water-glycerin mixtures. Tests with use of water showed that the deviation of the calculated and experimental characteristics from each other does not exceed 4%; the deviation of the characteristics of prototypes, manufactured using different technologies, is on average 1.5%. Tests with use of a water-glycerin mixture showed that the deviation of the characteristics from those obtained with use of water is on average 6%, the largest deviation is observed at the edges of the characteristics. In addition, when tested with use of a water-glycerin mixture, the deviation of the characteristics of prototypes, manufactures using different technologies, is about 4%, which is higher than when tested with use of water.
CONCLUSION: The results obtained allow us to conclude that the numerical model used in previous work can reliably predict the performance of the pump with use of water. The pressure characteristics of water and a water-glycerin mixture differ from each other, which must be taken into account when assessing the operating parameters of such pumps. The influence of manufacturing technology on the performance characteristics of the pump is higher when it operates with use of a liquid more viscous than water, e.g. on a water-glycerin mixture.

Published: September 2024

Restoring hyaline cartilage integrity remains a significant challenge in regenerative medicine. When damaged, the defect is replaced by fibrosis connective tissue, resulting in a loss of the biomechanical properties of the cartilage.
This review examines the intricate molecular mechanisms underlying reparative chondrogenesis and presents examples from a variety of animal species. It provides a comprehensive overview of the signaling pathways and cellular responses that promote cartilage repair, showcasing the regenerative abilities of fish and amphibians, including the little skate and axolotl, and surprising cases of chondrogenesis in mammals like the naked mole-rat and the Acomys mouse. Unraveling the dynamic interplay between growth factors, cytokines, and extracellular matrix components will shed light on the complex signaling pathways controlling reparative chondrogenesis.
The comparative analysis presented in this review reveals both conserved and species-specific molecular pathways involved in cartilage regeneration. This provides valuable information for translational studies. By uncovering the genetic and epigenetic determinants governing extreme examples of reparative chondrogenesis, this review provides a comprehensive framework for developing therapeutic strategies to improve cartilage repair in humans.

BACKGROUND: The steady increase in the number of inflammatory bowel diseases and the absence of reliably significant diagnostic markers require the search for new morphological criteria for differential diagnosis.
AIM: This study aimed to determine the cellular-differential composition of the intestinal epithelium in the phases of exacerbation and remission in Crohn’s disease and ulcerative colitis.
MATERIALS AND METHODS: Tissue samples of 60 patients with inflammatory bowel diseases (Crohn’s disease, n=30; ulcerative colitis, n=30) and with irritable bowel syndrome (control group, n=15) were studied using histological, immunohistochemical, morphometric and statistical methods.
RESULTS: Distinct features of the cellular-differential composition of the epithelium in the mucous membrane of the ileum, ascending colon, sigmoid colon, and rectum were identified across these conditions, with differences observed during exacerbation and remission in inflammatory bowel diseases. The proportion of goblet cells in the epithelial lining varied by intestinal region and disease type and phase.
Goblet cell differentiation: 25.0% more goblet cells of the superficial epithelium between the crypts of the ileum in acute Crohn’s disease compared with remission (p=0.0002); 42.9% more goblet cells in the superficial epithelium of the ascending colon compared with irritable bowel syndrome (p=0.0001); 23.0% more goblet cells crypt in the sigmoid colon compared with ulcerative colitis in the acute stage (p=0.0024). There were no significant differences in the differentiation of Paneth cells. There was a threefold increase in endocrinocytes in the sigmoid colon in acute Crohn’s disease compared with irritable bowel syndrome (p=0.0238).
Nonepithelial differon cells: fewer interepithelial lymphocytes in Crohn’s disease in remission compared with Crohn’s disease in the acute stage by 2.4 times in the sigmoid colon, 4.0 times in the rectum (p 0,0001); compared with irritable bowel syndrome by 4.8 times in the ileum, 2.7 times in the ascending intestine, 4.0 times in the sigmoid colon (p 0,05); 8.0 times in the rectum compared with ulcerative colitis in remission (p=0,0004). Additionally, the study found proliferative activity of crypt cells (mainly goblet-shaped) increased by 4.2 times in the sigmoid colon in acute Crohn’s disease compared with acute ulcerative colitis (p=0,0016).
CONCLUSIONS: Morphometric parameters of the cellular-differential composition of the intestinal epithelium can serve as potential differential diagnostic criteria. Acute Crohn’s disease is characterized by a higher proliferation index in the sigmoid colon compared with acute ulcerative colitis, while Crohn’s disease in remission shows a lower number of interepithelial lymphocytes in the rectum compared with ulcerative colitis in remission.

Over the past few decades, cochlear implants have undergone significant changes due to intensive research through experimental and computational analysis. However, obtaining an accurate and reliable cochlear model remains an open issue. Invasive measurements on the human ear are hardly possible, and the only alternative is animal models, but even this is not an ideal option, as animal cochleae are anatomically significantly different from the human cochleae. In this context, an ear model based on the latest knowledge of the physiology and molecular principles of hearing will allow the study of hearing disorders, whether they are caused by some genetic or external factors. It will also enable the experts to learn more about the detailed mechanisms of various forms of hearing impairment and open up avenues for the improvement of cochlear implants. With this in mind, the aim of this article is to explore different approaches to creating models of the human cochlea used in cochlear implant research. In the process of the study an individual emphasis is made on the variability of the human cochlea, sizes of its separate elements and shapes. Also considered are herein such methods of cochlea model creation as 3D-modeling, computer graphics and finite element method, as well as computational approaches. The results obtained allow us to state the fact that there are no ideal approaches and techniques to date available. The limitations of the models are related to difficulties in reproducing the microenvironment of the human cochlear apparatus, the need for clear validation and accurate parameterization of the main parameters of the cochlea. At the same time, we can expect that with a rapid increase in the available computational resources and development of effective computational methods, the models of the cochlea and cochlear implant will become more accurate and allow analyzing the cochlear micromechanics and the temporal response of the tissue to external stimulation.

A Granulomatose Eosinofílica com Poliangeíte (GEP), anteriormente conhecida como síndrome de Churg-Strauss, é uma doença autoimune rara que afeta principalmente adultos, caracterizada por vasculite e infiltração eosinofílica e formação de granulomas em diversos órgãos. Os sintomas incluem sinusite, asma, febre, fadiga e comprometimento renal. O diagnóstico é feito por meio de avaliação clínica, exames laboratoriais e estudos de imagem, enquanto o tratamento geralmente envolve imunossupressores, como corticosteroides e ciclofosfamida. Um relato de caso de uma paciente de 28 anos ilustra os desafios do GEP, incluindo problemas crônicos e dificuldades relacionadas à gravidez, ressaltando a importância do monitoramento e tratamento adequado para melhorar a qualidade de vida. O tratamento da GEP visa controlar a resposta autoimune e reduzir a inflamação. A GEP pode causar complicações graves, como insuficiência renal e distúrbios neurológicos, impactando significativamente a qualidade de vida dos pacientes. O suporte emocional e psicológico é crucial, pois a doença pode levar a problemas de saúde mental, como depressão e ansiedade. O acompanhamento médico regular e uma abordagem multidisciplinar são essenciais para o manejo eficaz da condição, destacando a importância do suporte contínuo e da resiliência para os pacientes.

O acidente vascular cerebral (AVC) é uma condição neurológica grave causada por isquemia ou hemorragia nas artérias cerebrais, levando a deficiências motoras e cognitivas. O AVC é uma das principais causas de mortalidade e incapacidade global, afetando cerca de 16 milhões de pessoas anualmente. A idade é um fator crucial, com a maioria dos pacientes tendo mais de 65 anos. Embora as taxas de mortalidade e prevalência tenham diminuído devido a avanços no tratamento, os números absolutos de mortes e anos de vida perdidos continuam a crescer. A reabilitação precoce é essencial para melhorar a recuperação funcional dos pacientes, e este artigo tem como objetivo investigar o impacto de estratégias de intervenção precoce na recuperação pós-AVC. Trata-se de uma revisão bibliográfica qualitativa descritiva, com busca sistemática em bases de dados acadêmicas (PubMed, Scopus, Google Scholar) usando descritores como “intervenção precoce pós-AVC”. O estudo, realizado em setembro de 2024, selecionou artigos originais e gratuitos em português ou inglês, excluindo trabalhos incompletos ou repetidos. O período pós-AVC é dividido em fases: hiperaguda (primeiras 24h), aguda (primeiros 7 dias), subaguda inicial (primeiros 3 meses), subaguda tardia (meses 4-6) e crônica (a partir de 6 meses). A recuperação depende fortemente do tempo, com os processos de plasticidade cerebral iniciando rapidamente após o AVC e variando em eficácia nas diferentes fases. Melhorias mais significativas ocorrem nas primeiras semanas, atingindo um platô após três meses, com possível recuperação adicional na fase crônica com intervenção contínua. A mobilização precoce tem papel controverso na fase aguda, e a fisioterapia, terapia ocupacional e terapia da fala são essenciais para a recuperação funcional e qualidade de vida. A abordagem multidisciplinar e personalizada, combinada com medicação para controlar sintomas e prevenir complicações, é crucial para otimizar os resultados. Recomenda-se continuar explorando e aprimorando práticas de reabilitação para maximizar a recuperação dos pacientes pós-AVC.

The purpose of this study — construction and research of a new mathematical model of a bilingual community, which takes into account: the effect of mutual assistance within a group of speakers of the same language, the effect of language acquisition by children of bilingual parents at an early age, different prestige of languages for adults. Methods. A new model is being built that takes into account new effects. The model is studied using classical methods with an unlimited increase in dynamics time. The effect of mutual assistance is compared with the effect of language volatility introduced by Abrams and Strogatti. Based on the observed statistical data, using the regression method, the parameters of some languages of England and Canada are determined: Welsh, Scottish, English, French. A forecast is being made for the further development of dynamics. Results. The effects taken into account in the model are confirmed by the correspondence of the development of language dynamics to the characteristics of the language: large values of the parameters of mutual assistance correspond to such a development of language dynamics in which one language displaces the second; at low values of mutual assistance, languages coexist. To model language dynamics using the new model, real statistical data on language pairs is used: Welsh-English, Scots-English, French-English. A forecast is being made for the further development of dynamics by language. Conclusion. General concepts in language dynamics have been supplemented with new ones — the power of mutual assistance within a group of speakers of the same language. The similarity between the effect of language volatility and the effect of mutual assistance is noted.

As discussões acadêmicas sobre a natureza da imagem em movimento e suas compreensões teórico-conceituais entre o campo/circulação/crítica do cinema e da arte contemporânea aparecem por meio de uma série de nomenclaturas que historicamente se debruçaram sobre modos específicos de tratar as passagens ocorridas entre mídias. Nesse contexto, a ideia de experimentalismo surge como conceito-chave para pensar a apropriação da imagem em movimento por artistas visuais e cineastas que, por um longo período, se viram em disputa por uma legitimação e uma circulação de suas produções em circuitos como os de festivais audiovisuais, a televisão e as exposições em galerias e museus (London, 2020). Em função disso, vimos a emergência histórica de nomenclaturas como “cinema experimental” (Bezerra; Carvalho; Herschmann; Murari, 2016), “cinema de artista” (Canongia, 1981; Parente, 2008), “cinema expandido” (Youngblood, 1970), “o outro do cinema” (Balsom, 2013; Bambozzi; Portugal, 2019; Bellour, 1997, 2008), “cinema de exposição” (Dubois, 2003, 2004; Garbelotti, 2019; Royoux, 2000) e “transcinemas” (Maciel, 2009). O que algumas dessas nomenclaturas possuem em comum é o fato de também emergirem das alterações no campo da imagem em movimento proporcionadas pela tecnologia do vídeo.

UMA REFLEXÃO SOBRE VIDEOPOESIA COMO GÊNERO LÍRICO INTERARTES
Authors: Santos Josiclei De Souza
Published: September 2024

ResumoA origem do gênero lírico durante muito tempo esteve ligada à performance, ao corpo e à voz, com a modernidade os poemas passaram para o suporte da página, mas o desenvolvimento tecnológico e a busca dos poetas modernos e depois contemporâneos em transcender os limites criativos da linguagem poética fez com que o gênero lírico se hibridizasse com outras linguagens artísticas e transcendesse o espaço da página. Dentre as linguagens com que o texto poético se hibridizou está o vídeo. A partir da criação e do acesso ao vídeo, artistas visuais e poetas perceberam uma ferramenta de grande possibilidade criativa, o que proporcionou a criação do gênero lírico híbrido, o videopoema. Para este estudo do videopoema enquanto gênero lírico interartes trabalhar-se-á principalmente com o conceito de Texto, de Barthes (1984) e de videoarte de Bambozzi (1994) e Machado (1997).Palavras-chave: Videopoema; gênero lírico; interartes.

ResumoO presente texto se propõe a refletir e problematizar sobre os sentidos, limites e potencialidades do museu de arte na contemporaneidade. Fundamentando-se em teses e teorias comprometidas com uma perspectiva decolonial, argumenta-se que muito embora a racionalidade neoliberal e o imaginário capitalista sejam preponderantes nos museus de arte, a implementação de políticas e práticas museais comprometidas com o devir decolonial e com uma política de cuidado poderiam contribuir não só no processo de despatriarcalizar, descolonizar e desocidentalizar do museu, mas também a reposicionar o museu desde o sul global enquanto um “objetor do poder” do museu ocidental.Palavras-chave: Museu de arte; capitalismo; devir decolonial.

La obesidad es una afección crónica y no transmisible relacionada con enfermedades cardiovasculares, diabetes, hipertensión arterial, cáncer, entre otras, por lo que es un grave problema de salud pública y una de las mayores epidemias del siglo XXI. Esta revisión narrativa tiene como objetivo presentar un análisis comparativo de diferentes métodos doblemente indirectos de medición de la composición corporal en humanos: aspectos prácticos, ventajas y desventajas. La búsqueda bibliográfica se realizó en las bases de datos PubMed, SciELO, BVS, Dialnet y ScienceDirect. Se incluyeron 77 artículos la mayoría publicados entre 2013 y 2023. Los métodos directos de medición de la composición corporal como la disección de cadáveres y los métodos indirectos como las imágenes diagnósticas son confiables y precisos. Sin embargo, los parámetros antropométricos (métodos doblemente indirectos) son más usados en la práctica clínica, en especial en el IMC y el PA, dado que aportan información relevante y confiable sobre la obesidad y el riesgo cardiometabólico. Los métodos directos e indirectos de medición de la composición corporal son poco asequibles y costosos, pero poseen una alta confiabilidad. Por su parte, los índices antropométricos son más prácticos y fáciles de medir a pesar de su discreta confiabilidad; además, son mucho más económicos, de fácil interpretación y de gran utilidad en estudios epidemiológicos.

Relevance. Nowadays water treatment technologies are universal. They consist of modules, the sequence of which may vary in the treatment scheme. It depends on the source of water supply and the purposes of treatment. The sorption purification stage is used in technology very oftеn. Sorption is used as the main stage of water treatment for treating wastewater. Also it is used as a post-treatment stage to obtain drinking water from natural sources. Stability of operation at different water temperatures, low cost, mechanical strength, possibility of regenerating sorbents and ease of use make the problem of modifying existing sorbents urgent to increase their selectivity and sorption capacity. Aim. To investigate the adsorption mechanism and sorption capabilities of the sorbent obtained by modifying AlOOH with silver ions in relation to inorganic ions and organic substances. Methods. X-ray phase analysis, method of thermal desorption of nitrogen, photocolorimetry, transmission electron microscopy. Results and conclusions. The sorbent was obtained by modifying aluminum oxyhydroxide with silver ions in a solution of silver nitrate with a silver ion concentration of 0.22 wt %. The physicochemical properties of the resulting sorbent were studied by X-ray phase analysis, transmission electron microscopy and the method of thermal desorption of nitrogen. The authors have determined phase composition and specific surface area as well as sorption kinetic parameters. They obtained sorption isotherms of inorganic ions and organic substances on aluminum oxyhydroxide modified with silver ions. Sorption isotherms were processed in Langmuir and Freundlich coordinates. The study showed that the resulting sorbent can be used in groundwater treatment technologies characterized by increased concentrations of organic substances.

Published: September 2024

Relevance. The use of natural diopside CaMgSi2O6 in the production of ceramic dielectrics was implemented at two enterprises in the Chelyabinsk region in 1985 on the basis of comprehensive studies of diopside rocks of the Southern Baikal region by the team of the Department of Silicate Technology of Tomsk Polytechnic University. Natural diopside was used as an additive to the charge of electrical porcelain. In addition, ceramic dielectrics with a diopside crystalline phase were manufactured for exploitation at the frequencies of 106 Hz. Currently, the need for ceramic dielectrics in Russia is covered by imports. Though, the development of new technologies for ceramic dielectrics from domestic raw materials is relevant. Aim. To develop an efficient technology for ceramic dielectrics with a diopside crystalline phase from natural low-iron diopside rocks. This technology includes the production of compacts of unfired products by moulding aqueous suspensions of compositions of nonplastic components. Object. The technology of ceramic dielectrics with a diopside crystalline phase, including the firing of compacts formed from aqueous suspensions of diopside concentrate compositions with perlite as flux. Methods. The suspension was obtained by grinding the components in an aqueous environment in a ball mill with uralite balls at humidity of 20±2%. Compressive and bending strength, electrical strength, dielectric constant of the samples were determined according to the SS 24409-80, water absorption was measured according to the SS 26093-84. X-ray phase analysis was carried out on a DRON-3M diffractometer (Burevestnik, Russia), structure analysis was implemented on a JSM 6000 electron microscope (Jeol, Japan). Results. A distinctive feature of the proposed technology is the use of nonplastic components only to prepare the suspension and the exclusion of clay components. This makes it possible to reduce the humidity of the castings and stabilize the formation of the ceramic structure during firing. The authors have obtained ceramic dielectric with a diopside content of 70±2 wt % by firing products molded at 1130–1150°C. The bending strength reached 85–90 MPa with an electrical strength of 35–38 k V/mm2.

Published: September 2024

Background: A feeding trial was conducted to find out the effect of aloe vera (Aloe barbadensis) supplementation on production performance, nutrient digestibility, mortality and cost of production of the layer chicken. Methods: Two hundred and twenty five laying chickens of twenty two weeks of age were randomly divided in to five treatment groups having three replications of fifteen birds each i.e. T0 (basal diet without antibiotic growth promoter, AGP-negative control group), T1 (basal diet with AGP-control group), T2 (T0+1% aloe vera), T3 (T0+2% aloe vera) and T4 (T0+3% aloe vera). Result: There was significant (P less than 0.05) difference in the average feed consumption (g/hen/day), hen day egg production, hen housed egg production, egg mass production, dry matter metabolizability and nitrogen retention upon supplementation of aloe vera in the diet of layers. The feed conversion ratio in terms of feed intake (kg) per dozen of eggs was significantly (P less than 0.05) lower in the control and 1% aloe vera supplemented groups as compared to the negative control group. Thus, it can be recommended that 1% aloe vera can be supplemented in the diet of layers as a herbal feed supplement.
