Authors: Cai Wei
Published: October 2022

In order to study the image recognition technology of traditional Chinese painting and calligraphy based on pseudo linear directional diffusion equation. Firstly, in the pixel domain, an overall style feature extraction algorithm of ink painting based on histogram is proposed, and then the local area with the most representative stroke style is located based on Sobel edge detection method to obtain the local detail style information describing the stroke. Then, using image processing, computer vision and other technologies, combined with some quantifiable authenticity identification indexes of Chinese painting, this paper designs a authenticity identification method of Chinese painting based on image recognition to assist the authenticity identification of Chinese painting and improve the reliability of authenticity identification. The experimental results show that the fusion algorithms based on information entropy and distance are proposed in this paper. On the premise of maximizing the artistic style, the fusion algorithm combines the advantages of the overall and local class results, so as to realize the automatic classification of ink painting based on artistic style and output the classification results.

Authors: Malee Wantanee , Ruang-on Somporn , Hussain Naeem , Tina Fahmida Wazed
Published: October 2022

In Thailand, mangosteen (Garcinia mangostana) production is essential for domestic consumption and export. Mangosteen without scars on their surface is considered high-quality fruit. Scars reduce their market demand. The common cause of scars is thrips infestation. Humidity is an important climatic factor that affects the thrips populations. Lower humidity inside the mangosteen canopy increases the thrips numbers. Thus, increasing humidity can control the thrips population. This study developed a smart watering system to increase the humidity inside the mangosteen canopy in Nakhon Si Thammarat province, southern Thailand. This system provided water automatically and increased humidity inside the mangosteen canopy.

Characterisation of ORF3, M, N and E gene sequences of porcine epidemic diarrhoea virus from domestic pigs in Poland
Authors: Olech Monika , Antas Marta , Szczotka-Bochniarz Anna
Published: October 2022

Introduction

Porcine epidemic diarrhoea virus (PEDV) is an enteric pathogen causing porcine epidemic diarrhoea and acute gastroenteritis in pigs of all ages. Previous analysis of the viral genome of PEDV in Poland was only based on the spike protein (S) gene sequences and no analysis of other genes has been performed. The aim of this study was to analyse the envelope (E), membrane (M) and nucleocapsid (N) protein and open reading frame 3 (ORF3) gene sequences.

Material and Methods

Viral RNA from 18 Polish pig faecal samples that were quantitative reverse transcription PCR-positive for PEDV was analysed in four genomic regions (E, M, N and ORF3).

Results

Phylogenetic analysis based on these regions’ sequences revealed that Polish PEDV isolates were highly related and were clustered into group G2a across the four genes compared. Moreover, the Polish strains were located in distinct subclusters on the phylogenetic trees, which suggests the presence of at least three independently evolving PEDV genetic lines circulating in Poland. The occurrence of unique mutations in the sequences of Polish PEDV strains suggests that PEDV continues to undergo evolutionary processes, accumulating the mutations necessary for viral fitness in its natural hosts. The Polish PEDV strains differed genetically from the CV777 vaccine strain, suggesting the risk of relatively low vaccine efficacy if this strain is used.

Conclusion

Our results promote a better understanding of the genetic diversity of PEDV field isolates in Poland and highlight the importance of molecular characterisation of PEDV field strains for the development of an effective vaccine against PEDV.
Stone Industry of the Bronze and Iron Ages Border (case study of the Oralovskoe Ozero II settlement on the Vishera River)

The authors publish the data on the stone assemblage of the Oralovskoe Ozero II settlement, 9th – 8th century B.C., the Kama River basin, Perm Krai, Russian Federation. Examination of the traces of processing on the ﬂint artefacts made it possible to determine its basic characteristics. These are a stadial knapping; secondary bifacial thinning; heat treatment of the raw material to prepare it for knapping; leaf-shaped bifaces with a straight base – arrowheads and dart/spear points, decorated at the fnal stage with «serrated» retouching; unifacial scrapers. The search for assemblages with similar characteristics allowed to determine in the extreme north-east of Europe (the basins of the Pechora, Vychegda and Mezen rivers) a special tradition of the ﬂint tools production of the Bronze and Iron Ages boundary. Reference stone assemblages accompany different types of pottery and their combinations: Korshak and Lebyazhskaya cultures, Ananyino cultural-historical community and ceramics with “cross-like” ornamentation. This indicates that mobile foragers established links with tundra and taiga cultures, uniting them into a single network of the Bronze and Iron Age boundary in the north-east of Europe. A detailed analysis of the identifed stone-working tradition, its naming, the search for origins and spatial and temporal variants is needed in the future.

Authors:   Institute of Archaeology, Ethnography and Anthropology, National Academy of Sciences of Azerbaijan, Museibli Najaf Alesker oglu
Published: October 2022

Since ancient times the Nakhchivan region of Azerbaijan has been part of the Middle Eastern cultures. Nakhchivan region is located on the one side in the basin of Lake Urmia, on the other in the immediate vicinity of Eastern Anatolia, in close proximity to Mesopotamia. Cultural processes in this region of the ancient East directly affected the territory of Nakhchivan. One of the richest archaeological monuments of Nakhchivan is Gemigaya complex. The Gemigaya monuments located in the high mountainous area are mainly rock paintings – the Bronze-Early Iron Age petroglyphs. Numerous fgures of people, farm animals, wild animals, carts with ancient vehicles, various signs are engraved on the monument. Analogues of some of Gemigaya paintings can be found on archaeological materials of the Middle East. At the same time, a number of human paintings of Gemigaya are stylistically close to some anthropomorphic clay fgures of the ancient East. Such close similarities are the result of the close ties of the ancient South Caucasian population, including Nakhchivan, with the centers of civilization in the Middle East. These relations are also reﬂected in the fne arts.

Outcomes of a rural-focussed family practice residency
Authors: Stover Dr. Sandra , Lasswell Julia , Friedrichsen Samantha , Emery Rebecca
Published: October 2022

Purpose: Family medicine  physicians play a crucial role in maternity care in community-based settings. However, residency graduates are decreasingly likely to provide delivery services. We explored residency training and graduates' inclusion of obstetrical care in practice by surveying graduates of the Duluth Family Medicine Residency, traditionally producing a high number of graduates serving rural communities and providing obstetrical care.

Methods: Graduates (N=48) were surveyed about their provision of maternity care and perceptions of how well the residency prepared them to provide such services. Additional factors that impacted decisions to provide obstetric care (e.g., post-residency training, community size, and if there were obstetricians providing delivery services in their community) were evaluated.

Findings: Nearly half of graduates (46%) were providing maternity services, most of whom provided perinatal clinical care (68% provided delivery care and 4% operative deliveries).  Seventy-one percent worked in a community with an available obstetrician. Graduates providing obstetric services were more likely to live in rural communities (66% vs 35%, p<0.01). Thirty percent of graduates received extra obstetrical training in residency. Graduates providing obstetric services were more likely to cite that their decision to practice obstetrics was influenced by the number of deliveries performed, interactions with attending obstetricians, and interactions with prenatal and laboring patients during residency compared to those not providing obstetric services.

Conclusions: Residency training has an impact on provision of maternity care and potential practice of family physicians in rural communities. Attention to curricular support, particularly exposure to maternity patients, is important for resident comfort in obstetrics.
Perceptions of Social Determinants of Health in a Student-Led Free Clinic
Authors: Crump William J. , Parker Sarah
Published: October 2022

Understanding a patient’s social determinants of health (SDOH) needs is an important aspect of medical care. To understand better how well future physicians are aware of these needs, student primary care providers (PCP) at a student-led free clinic in the upper southeastern United States surveyed fifteen patients via telemedicine between October 2020 and January 2021 concerning their social determinant of health needs. Seventeen social determinants of health items were addressed using a 10-point Likert scale. Prior to administering the survey to patients, student PCPs were asked to complete the survey to predict each individual patient’s response. The average difference between student and patient response ranged from 1.3 to 3.8 for each SDOH item, and patients expressed a higher need than their PCP students did for health services navigation, health insurance limitations, and education options and affordability. We conclude that even this group of motivated medical students providing continuity care could benefit from a more formal curriculum addressing SDOH.

Gardening in Polluted Tropics: The Materiality of Waste and Toxicity in Olive Senior’s Caribbean Poetry
Authors: Muñoz Martínez Ysabel
Published: October 2022

While toxic substances continue increasingly, and unevenly, infiltrating the world, the new materialist turn invites us to examine the relationalities emerging between pollution and literature. This essay examines how Olive Senior’s poetry collection Gardening in the Tropics portrays the imposition of waste and toxicity on Caribbean islands and the counter-narratives to toxic politics that emerge from non-hegemonic perspectives. The paper utilizes methodological contributions from the fields of waste studies, postcolonial and material ecocriticism, and addresses the need for more scholarship centering toxicity in cultural studies, especially through the lens of tropical materialisms. Moreover, the research engages with theorizations surrounding the concept of the Wasteocene as a novel interpretative framework. The main findings reveal that the poems “My Father’s Blue Plantation”, “The Immovable Tenant” and “Advice and Devices” identify how extensive pollution is enabled and perpetuated by colonial systems. The poems illustrate the environmental and socio-political tensions prompted by toxicity, its deleterious effects in organisms and landscapes, and embody how guerrilla narratives can confront widespread toxicity.

Population projection is not a population forecast but a scientific calculation based on assumptions of the components of the population growth rate, namely births, deaths and migration. These three components determine the size of the population and the age structure of the population in the future. In order to determine the assumptions of future developmental levels of births, deaths and displacement, data are needed that describe trends from the past to the present. Here the author will determine the projected population growth in Sumenep Regency on Madura Island using a logistic growth model. The population census of Sumenep Regency was obtained from the BPS (Central Statistics Agency) of Sumenep Regency from 2010 to 2020. Based on the results of the study, it was obtained that the Craying capacity was 1,141,132.5.

Unsteady Aerodynamics Around a Pitching Airfoil with Shock and Shock-Induced Boundary-Layer Separation
Authors: Oyeniran Noah D. , Miyake Toma , Terashima Hiroshi , Seki Ryoto , Ishiko Keiichi , Nonomura Taku
Published: October 2022

This study numerically investigated the characteristics of unsteady aerodynamic forces around a pitching airfoil in the transonic flow regime. The unsteady Reynolds-averaged compressible Navier–Stokes (URANS) equations were solved using a Spalart–Allmaras (SA) turbulence model. The pitching NACA64A010 airfoil at mean angles of attack of 0, 2, 4, and 6 deg with the amplitude of 1 deg and reduced frequency of 0.2 was parametrically simulated. The study found that the trend of the unsteady aerodynamic characteristics around the pitching airfoil, particularly that of the unsteady lift force, significantly changes with the mean-angle-of-attack conditions. The shock-induced boundary-layer separation and reattachment during the pitching oscillation have a crucial role in determining the trend of the unsteady aerodynamic forces, such as the phase-delayed or phase-advanced features for the variation in the angle of attack. The boundary-layer separation during the oscillation, observed at a high mean angle of attack of 6 deg, produces the phase-advanced feature of the lift force. Because the phase-advanced feature is associated with a positive damping effect, the result indicates that the boundary-layer separation may serve as a stabilizing effect on the pitching airfoil motion. The boundary-layer reattachment from separation during the airfoil oscillation, observed at an intermediate mean angle of attack of 4 deg, generates an unusual shock wave movement, resulting in a unique lift loop for the variation in the angle of attack. The study also demonstrated a good prediction accuracy of the URANS with the SA model for the unsteady aerodynamics around the pitching airfoil with the shock and shock-induced boundary-layer separation.
Application of Leading-Edge Tubercles on Rotor Blades
Authors: Colpitts Ryley , Perez Ruben E.
Published: October 2022

This study explores the effects of leading-edge tubercles applied to a canonical rotor blade in an effort to improve aerodynamic performance of a rotor in hover, without sacrificing forward flight performance. Various tubercle shapes and configurations were analyzed using computational fluid dynamic simulations using Euler and Reynolds-averaged Navier–Stoke equations. Improvements in figure of merit up to 3% were found over the baseline rotor for specific tubercle configurations when operating at pitch angles between 2 and 11 deg and tip Mach numbers between 0.6 and 0.83. An increase in thrust coefficients and reduction in power coefficients over the baseline rotor were both attributed to alteration of flow behavior in different regions of the rotor blade when leading-edge tubercles were applied.

Titanium aluminides have a low density and maintain high strength at elevated temperatures, which makes them prom-ising for the manufacture of aircraft engine elements. In the presented work, the problem of welding in the solid phase ortho-rhombic titanium aluminide based on the intermetallic compound Ti2AlNb and heat-resistant alloy ЭИ437Бon a nickel base is considered. A review of the state of the problem of welding heat-resistant alloy ЭИ437Бbased on nickel and titanium or-thoaluminide Ti2AlNb was carried out. It was established that the main problem in welding Ti2AlNb alloy with nickel alloy is a strong tendency to the formation of brittle phases in the joint zone, which negatively affect the mechanical properties. A promising method of joining this group of alloys is diffusion welding in a vacuum.The purpose of the work is to study the influence of multilayer and gradient foil on the formation of the zone of titanium orthoaluminide joints with a nickel-based alloy during vacuum diffusion welding.In the work, multilayer and gradient foil based on Al-Ni and Ni-Tisystems were used according to the original structure. The foils were obtained by electron beam evaporation and condensation in a vacuum. The deposition process consists in the layer-by-layer condensation of elements on a horizontal substrate.The work presents the method of conducting experiments, welding modes, chemical composition of materials and foil.The work shows for the first time that during the direct welding of titanium orthoaluminide with the ЭИ437Бalloy, as a result of the strong tendency ofthe materials to form brittle phases at the joint, a significant increase in microhardness is observed in the joint zone up to 2...4 times compared to the base material (up to 11.94 GPa). It was established that the useof layered foil (Ni/Ti, Al/Ni) as intermediate layers allows to significantly reduce the difference in microhardness values in the joint. At the same time, the microhardness in the central part of the joint zone reaches 6.69...8.79 GPa, which is close to the microhardness values of Ti2AlNb.The presented materials can be used as a basis for the development of welding technologies in the solid phase of heter-ogeneous titanium orthoaluminide materials with nickel-based alloys.

The article contains a scientific and methodical study on the installation of machines tool and other equipment directly on antivibration supports and the selection of specific types of these supports based on comparative evaluation and with confirmation of their compliance with operational requirements. The results of the research are relevant and can be applied by engineeringand technical workers of machinery manufacturing plant in the case of modernization of existing equipment, primarily at small enterprises, since the solution of the problem should not involve complex dynamic studies and calculationsthat require appropriate specialists and equipment.The main attention is paid to consideration of different types of antivibration supports. The correct choice of supports makes it possible to isolate the equipment from the action of internal (caused by the design of the machine tool and the cutting process itself) and external vibrations and to ensure both the accuracy of the relative location and movement of the machine units, as well as the reduction of the level of elastic movements and amplitudes of oscillations. The best option is the experimentally based recommendation of the manufacturing plant regarding the suitability of the selected supports, but it is valid for new machines tool, and even then, the operating conditions are not properly considered. The analysis of information sources showed that, despite the presence of dynamic studies, the necessary information is missing or quite outdated and generalized, which allows it to be used as an estimate, but not as final. The recommendations need to be updated accordingly and reconciled with the requirements for modern machines tool.

Objetivo: Descrever os problemas éticos relacionados ao aleitamento materno descritos na literatura científica. Métodos: Trata-se de uma revisão integrativa da literatura, realizada nas bases de dados: SciELO, MEDLINE/PubMed e Web of Science a partir do cruzamento de descritores disponíveis nos Descritores das Ciências da Saúde (DeCS) e Medical Subject Headings (MeSH), Ethics e Breastfeeding, combinados por meio dos operadores booleanos AND e OR. Resultados: Identificou-se duas categorias temáticas, sendo elas: PEs na prática do aleitamento materno, que refletem sobre a necessidade de apoio às mulheres pela família, profissionais de saúde e sociedade considerando os aspectos biopsicossociais e econômicos, e PEs envolvendo os substitutos do aleitamento materno, que questiona os valores éticos dos profissionais prescritores das fórmulas infantis. Considerações finais:  Verificou-se a presença de PEs vinculados à prática do aleitamento materno e aos seus substitutos, sendo essas tomadas de decisão igualmente sensíveis e desafiadoras.  Eles advém de situações como: necessidades da criança versus necessidade da mãe, falta de apoio, continuidade da amamentação por mães soropositivas e valores éticos dos profissionais que prescrevem formulados. O estudo considera que as tomadas de decisões e a assistência ao binômio mãe-filho devem ser amparadas em princípios éticos que considerem a integralidade do cuidado.

Objetivo: Levantar as crenças sobre o uso de máscaras durante a pandemia da COVID-19. Métodos: Estudo descritivo com abordagem quanti-qualitativa. A amostra foi composta por pessoas maiores de 18 anos, não profissionais de saúde, com domínio para gravação e envio de áudios por redes sociais. Foram utilizados os pressupostos da Teoria do Comportamento Planejado, com perguntas abertas, em uma entrevista estruturada individualizada, buscando por crenças (comportamentais, normativas e de controle), posteriormente submetidas à análise descritiva e de conteúdo. Resultados: Entende-se a importância de identificar crenças sobre o uso de máscaras como medida preventiva para pandemia da COVID-19, os achados revelam que os familiares e entes mais próximos, apresentam forte influência para adesão, outros afirmaram que o uso de máscaras traz benefícios no que diz respeito ao controle e transmissão, destaca-se também a facilidade do uso de máscaras, porém, alguns indivíduos relataram dificuldade de acessibilidade para utilização. Conclusão: Estas crenças estão extremamente conectadas a adesão ao uso de máscaras e com a prevenção e disseminação da COVID-19, o que se torna uma ferramenta essencial para o conhecimento dos indivíduos e revelam quais estratégias serão mais adequadas para os profissionais utilizarem, resultando em uma assistência à saúde multidimensional.
