To study the effect and mechanism of selenium sources on the selenium content and quality of fresh tea leaves, tea seedlings (Camellia sinensis (L.) O. Kuntze) were the research object. A solution of 100 mg/L sodium selenate (Na2SeO4), sodium selenite (Na2SeO3), and selenium yeast (selenium yeast) were applied on the leaves surface of 5-week-old tea plants, and the selenium levels in the leaves, roots, and stems were determined at 20 weeks of age. The effects of different selenium sources on the mineral nutrient content, antioxidant enzyme activity, and quality parameters content in leaves were analyzed. The mechanism was analyzed by detecting the expression levels of related genes. The results showed that the three selenium sources can increase the growth of tea seedlings and the selenium content in leaves and stems, and the selenium yeast treatment had the most significant effect. Selenium spraying promoted the absorption of mineral nutrients such as nitrogen, phosphorus, and potassium, but had no significant impact on the absorption of calcium and magnesium. Spraying the three selenium sources dramatically increased the activities of APX, POD, and SOD antioxidant enzymes, among which the selenium yeast treatment had the most significant effect. However, there was no significant impact on the MDA level in this study. Selenium sources markedly increased leaves total amino acid levels, accompanied by up-regulation the genes of amino acid synthetic enzymes (CsGS, CsGOGAT, and CsGDH). Leaves glucose, tea polyphenol, total soluble protein, catechin, flavonoid contents, and sucrose were higher in selenium sources treatments than in control treatment seedlings. Moreover, selenium sources up-regulated expression of CsHMGR, CsAPX, and CsTCS1 genes. selenium yeast had the best comprehensive effect of the three selenium sources. These results confirmed that selenium sources play a positive role on the selenium content and quality of tea by increasing the antioxidant capacity of leaves, the absorption rate of mineral nutrients, and regulating expression of related genes in Camellia sinensis.

Salinity stress (SS) is serious abiotic stress and a major limiting factor for crop productivity and global food security. In this context, the application of osmolytes is considered as an environmental friend approach to improve plant growth under SS. Thus, the present study was conducted to determine the impact of foliar applied proline (Pro) and acetic acid (AA) on growth, yield, physiological traits, photosynthetic pigments, ionic homeostasis and antioxidant activities of wheat under SS. The study contained SS levels 0, 6 and 12 dS m-1 and foliar spray of Pro and AA; water spray, Pro (75 mM), AA (15 mM) and AA (30 mM). The study was conducted in a completely randomized design with the factorial arrangement. Salinity stress significantly reduced wheat growth and yield, by decreasing relative water contents (-49.07%), photosynthetic pigments, free amino acids (FAA: -44.79%), total soluble proteins (TSP: -15.94%) and increasing the electrolyte leakage (EL: +27.28%), hydrogen peroxide (H2O2: +51.86%), and malondialdehyde (MDA: +36.91%) accumulation. The foliar spray of Pro and AA markedly improved the wheat growth and productivity through enhanced photosynthetic pigments, RWC, FAA, TSP, antioxidant activities (catalase: CAT, ascorbate peroxide: APX: peroxidase: POD), K+ and Ca2+ uptake and decreasing EL, MDA and H2O2 accumulation and restricted entry of toxic ions (Na+ and Cl-1).  Therefore, foliar application of AA and Pro effectively improves the growth and yield of wheat under SS by strengthening the antioxidant defense system, and maintaining ionic homeostasis and physiological performance.

Published: September 2022

Os públicos têm ganho crescente importância enquanto agentes das instituições culturais, de modo que a auscultação dos seus discursos e avaliações sobre as instituições e sobre os produtos culturais constituem relevantes instrumentos para a gestão da missão cultural e para as políticas culturais.
Importante componente de participação e de avaliação, a recolha das opiniões e sugestões dos visitantes das instituições museais revela potencialidades na medida em que o próprio discurso dos atores é objeto de análise. Um modelo analítico que dê sentido às opiniões e sugestões dos públicos com vista à sua incorporação no planeamento e gestão das instituições museais é um passo importante nesse sentido.
Este artigo versa sobre uma grelha de análise de testemunhos escritos após a visita a museus e exposições. A sua construção foi realizada no âmbito do Estudo de Públicos de Museus Nacionais (EPMN), que incluiu um universo de 14 museus (n= 6.656) (Neves e Mourão, 2016). Num segundo momento, e partindo da base empírica dos estudos destes museus, foi aplicada na análise dos públicos regulares (n= 912) no Grupo de Projeto Museus no Futuro (Camacho, 2021). A grelha foi novamente aplicada e testada no contexto de outra recolha empírica em 2019, sobre os públicos de uma exposição temporária - Loulé: Territórios, Memórias e Identidades (LTMI) - que decorreu no Museu Nacional de Arqueologia (Neves, Santos e Apolinário, 2020).
Neste artigo, faz-se um enquadramento teórico sobre os públicos e sua relevância para as instituições museais, apresenta-se a metodologia subjacente à construção da grelha interpretativa e explicita-se as ilações descorrente da sua aplicação.
Concluímos que as sucessivas aplicações da grelha permitem sustentar a adequação e pertinência do modelo e as condições da sua generalização à análise das opiniões e sugestões, em contextos diferenciados, e a solicitações também diversas tanto do ponto de vista teórico como empírico.

RESUMO Objetivo: determinar a prevalência e descrever as principais variações morfológicas e métricas da artéria esplênica quanto a sua origem, trajeto e ramos terminais e polares. Métodos: estudo transversal, realizado no Hospital de Clínicas entre julho e novembro de 2020. Foram analisadas tomografias computadorizadas com contraste endovenoso dos pacientes atendidos no Serviço de Radiologia e Diagnóstico por Imagem. Os achados foram categorizados quanto à origem, trajeto e ramificações esplênicas. Resultados: foram avaliados 1.235 pacientes. Quanto à origem, a artéria esplênica surge no tronco celíaco em 99,11% dos indivíduos. Desses, 5,95% apresentam padrão celíaco bifurcado, 92,17% trifurcado e 1,88% tetrafurcado. O diâmetro arterial médio foi de 5,92mm (±1,2), sendo a maior média em homens brancos. Quanto ao trajeto, a artéria esplênica se apresentou única em toda a amostra. O curso suprapancreático esteve em 75,63% dos indivíduos, com maior ocorrência em mulheres 78,87% (p<0,001). O padrão de divisão terminal da artéria esplênica caracterizou-se pelo tipo bifurcado (95,47%). Os ramos terminais visualizados mais frequentemente foram os com três artérias (34,90%) e a maioria dos indivíduos não apresentou ramos polares. Conclusão: a artéria esplênica apresenta padrão de origem altamente variável e seu calibre médio é influenciado por sexo e cor. O trajeto suprapancreático foi o mais característico e predominou no sexo feminino. O padrão bifurcado de divisão final, com três ramos terminais e ausência de artérias polares, ocorre com maior frequência.

RESUMO Os processos de mudança organizacional estão se tornando cada vez mais comuns sob a óptica de estratégias, reestruturações ou tecnologias, sem levar em conta a mudança de relações que envolve o indivíduo com a organização, com a sociedade e consigo mesmo. Muitas pessoas estão valorizando menos os conceitos tradicionais como lealdade, autoridade, antiguidade ou promoção, de forma que o trabalho, a família, o autodesenvolvimento e a carreira possam receber atenção substancial. Este contexto coloca em evidência as particularidades da força de trabalho do serviço público federal brasileiro e a sua interrelação com o sistema de carreira, que foi adotado para esta classe de trabalhadores. Assim, o presente ensaio tem por objetivo adentrar no universo das teorias que exploram as características da carreira pública federal brasileira, com o intuito de defrontá-las com as teorias e tendências que abarcam a temática na atualidade. Para alcançar esse objetivo foi realizada uma pesquisa bibliográfica a partir de uma abordagem qualitativa, com natureza de ensaio teórico, em que se observou que existe um descompasso entre a realidade da carreira pública federal brasileira e a evolução das teorias que lidam com o tema.

Como fazer um povo existir: ritual, política e parentesco entre os Karo-Arara de Rondônia
Authors: Santos Júlia Otero dos
Published: September 2022

Resumo Este artigo interpela uma questão premente na etnologia amazônica, a saber, a insuficiência ou os limites de categorias como povo, cultura, etnia ou sociedade para narrar as experiências de nossos interlocutores e interlocutoras de pesquisa. Em diálogo com a noção de objetificação de Marilyn Strathern, com as ideias de Tânia Stolze Lima sobre grupos-sujeitos e totalização contra-hierárquica, e com a teoria do ritual de Roy Wagner, procura-se mostrar como, entre os Karo-Arara de Rondônia, um povo é a instanciação de um coletivo estendido de parentes que somente pode vir a existir sob uma forma específica e convencional, em contextos rituais, e capitaneado por sujeitos concretos. O exercício analítico parte da etnografia de uma festa, o Wayo ‘at Kanã, que é entendida pelos meus interlocutores como, entre outras coisas, uma apresentação.

Published: September 2022

Resumo Com retrocessos se acumulando no Brasil em relação às questões climáticas e indígenas, especialistas em temas socioambientais têm procurado identificar fatores e agentes que operam para dar sustentação a esse quadro. Um dos principais atores apontados na literatura científica é a Frente Parlamentar da Agropecuária (FPA), um bloco multipartidário com poder em ascensão no Congresso Nacional. Este artigo apresenta uma etnografia do núcleo estratégico no qual se negociam e se definem os posicionamentos oficiais da FPA: o Instituto Pensar Agropecuária (IPA). O primeiro objetivo é analisar os três conjuntos de atores que operam no âmbito do IPA: organizações empresariais, agentes técnicos e parlamentares da mesa diretora da FPA. O segundo é examinar como essa engrenagem tripartite é operacionalizada. O trabalho está baseado em observação participante no IPA e no Congresso Nacional, em entrevistas com agentes privados, técnicos e políticos que integram o instituto e em documentos corporativos e estatais. Os resultados indicam que a consolidação do IPA inflexionou de maneira expressiva a representação de interesses das elites dos sistemas alimentares que operam no país.
Agile project management under the perspective of dynamic capabilities

Published: September 2022

Abstract: There is a growing academic and industrial interest in how firms can adopt agile project management to meet the demands of dynamically fast-moving environments. However, organizations face difficulties using agile methods in developing a physical product, like the companies found in the automotive industry. This article aims to study agile project management from the perspective of dynamic capabilities. It presents a strengthened analysis of the adoption of agile methods needed for developing physical products in the automotive industry. To address this issue, we formulated the following research question: “what are the dynamic capabilities associated with the agile project management of product development in the automotive sector?”. The article presents a case study of a multinational organization in the automotive sector that implemented concepts and practices of agile methods in the project management of new vehicles. Results evidenced the manifestation of dynamic capabilities in the organization's agile project management scope at sensing, seizing, and reconfiguring levels. Furthermore, findings showed the presence of agile methods in the projects and their implications for the organization regarding benefits (like communication, time, effectiveness, autonomy, and motivation gains) and challenges (like resistance to organizational changes). Finally, we propose a framework for analyzing relationships between dynamic capabilities’ microfoundations and agile project management practices to guide the choice and implementation of agile methods in the automotive sector.

Abstract This research aims to define factors that influence accounting students in choosing their careers after graduated. There are two gaps of previous studies that we try to cover in this study. Firstly, previous studies only focused on one university or one region in a country. Secondly, they only examined a specific career choice, mostly as public accountants. This study is conducted on Indonesian accounting students and it set the respondents to choose their careers in the beginning and fill the questionnaire based on that career choices. The output of this study is career choice factors of Indonesian accounting students’. By understanding those factors, this study provide awareness and insights for parents, lecturers, and universities to prepare students for their future careers. The results imply the need for collaboration between family and university. On one side, parents should not push a certain career path to students, rather they should encourage students to choose careers suitable for needs and expectations. On the other side, university should ensure that the quality of their graduates suits to the needs and the expectation of users. Data were collected by conducting an online survey to the population of final-year accounting students in Indonesia. Three hundred and fifty-eight respondents participated in this survey. Factor analysis was used for data analysis. The result of this research confirmed all factors that determine career choices of accounting students. Those factors are social values, rewards, job market certainty, professional recognition, work environment, and family. Interestingly, the family factor is divided into two factors: family support and family environment.

Abstract This study aimed to evaluate the effect of the first and last stocking strategies combined with a partial substitution of the protein from the supplement for urea nitrogen on nutrient intake and digestibility, milk composition, and nitrogen balance of primiparous Girolando cows. The cows were allocated to a double 4 × 4 Latin square composed of four animals and four treatments in a 2 × 2 factorial arrangement. Supplements were formulated to provide an intake of 0.6% body weight, with and without the inclusion of 21% urea nitrogen in their composition. The first stocking management method improved nutrient intake and digestibility. Supplementation with urea led to a 47% higher excretion of urine N (g/day) than the urea treatment. The combination of the supplement without urea and the first stocking provided higher intake and retention of nitrogen and higher retained-N levels (%digested N). The combination of a supplement containing 21% urea nitrogen and the first stocking can be used without compromising the nutritional and productive parameters of the cows.

Resumo Objetivou-se avaliar os efeitos dos manejos do pastejo ponta e repasse combinados a substituição parcial da proteína do suplemento por nitrogênio ureico sobre o consumo e digestibilidade dos nutrientes, composição do leite e balanço de nitrogênio de vacas primíparas da raça Girolanda. As vacas foram alocadas em dois quadrados latinos 4 x 4 compostos de quatro animais cada e quatro tratamentos em um esquema fatorial 2 x 2. Os suplementos foram formulados para um consumo de 0,6% do peso corporal: sem utilização de nitrogênio ureico; ou com 21% de nitrogênio ureico em sua composição. O manejo do pastejo de ponta melhorou o consumo e a digestibilidade dos nutrientes. O suplemento contendo ureia excretou 47% a mais de N urina (g/dia) em comparação ao suplemento sem ureia. A combinação entre o suplemento sem ureia e o manejo de pastejo ponta apresentou maior ingestão e retenção de nitrogênio e maior N retido (%N digerido). A combinação entre o suplemento contendo 21% de nitrogênio ureico e o pastejo de ponta pode ser utilizada sem prejuízos aos parâmetros nutricionais e produtivos das vacas.

Abstract This study aimed to evaluate the efficacy of mesenchymal stem cells (MSC), alone or associated with dapsone (DAP), in treating dermonecrotic wounds caused by Loxosceles laeta venom. Twenty-five male rabbits were distributed into five groups. Negative control received ultrapure water (C-), whilst all other groups were injected with 20 μg of L. laeta venom. After 4 hours, each group received one of the following treatments: PBS (C+), DAP, MSC, and DAP+MSC. Animals were evaluated daily and photographic records made for analysis of wound area. Twelve days after, animals were euthanized and skin samples removed for histological analysis. We observed that DAP showed the best percentage of wound contraction at day 3. In the treatments using MSCs, a negative value of wound contraction was observed for the isolated MSCs, as well as a lower contraction value for the association of the MSC + DAP when compared to PBS, probably, by the increase in initial infammation after the application of stem cells, due to the fact that MSCs secrete a broad spectrum of bioactive molecules such as cytokines and growth factors that favor regeneration. Histologically, it was observed that animals of C+ showed extensive areas of necrosis, ulcers, neutrophilic infiltrate, and mineralization. Collagen deposition showed increase in MSC+DAP treatment, however vascularization remained unchanged. This is the first report using MSC and MSC+DAP as a treatment for cutaneous loxoscelism and more studies are needed to determine its use as an alternative therapy for dermonecrotic lesions caused by Loxosceles spider.

Resumo Este estudo teve como objetivo avaliar a eficácia das células-tronco mesenquimais (CTMs), isoladas ou associadas à dapsona (DAP), no tratamento de feridas dermonecróticas causadas pelo veneno de Loxosceles laeta. Vinte e cinco coelhos machos foram distribuídos em cinco grupos. O controle negativo recebeu água ultrapura (C-), enquanto todos os outros grupos foram injetados com 20 μg de veneno de L. laeta. Após 4 horas, cada grupo recebeu um dos seguintes tratamentos: PBS (C+), DAP, CTMs e DAP + CTMs. Os animais foram avaliados diariamente durante 12 dias, e feitos registros fotográficos para análise da ferida e no 12º dia, foram eutanasiados e, retiradas amostras de pele para análise histológica. Observou-se que a DAP apresentou o melhor percentual de contração da ferida no terceiro dia. Nos tratamentos com CTMs, observou-se uma contração negativa da ferida tanto para as CTMs isoladas, bem como a associação CTMs + DAP em relação ao PBS, possivelmente, pelo aumento da infamação inicial após a aplicação de células-tronco. Isso é devido ao fato de que as CTMs secretam um amplo espectro de moléculas bioativas como citocinas e fatores de crescimento que favorecem a regeneração. Histologicamente, observou-se que os animais de C+ apresentaram extensas áreas de necrose, úlceras, infiltrado neutrofílico, além de mineralização. Houve aumento de deposição de colágeno no tratamento CTMs + DAP, no entanto, a vascularização permaneceu inalterada. Este é o primeiro relato usando CTMs e CTMs + DAP como tratamento para loxoscelismo cutâneo e mais estudos são necessários para determinar seu uso como terapia alternativa para lesões demonecróticas causadas pela aranha Loxosceles.

ABSTRACT In the climate change scenario, studying greenhouse gases (GHG) emissions and measures of mitigation in the Caatinga biome are strategic and may provide a basis for mitigation plans. This study aimed to evaluate the soil CO2, CH4 and N2O fluxes, as well as determining an annual baseline for GHG emissions, in a reference site of silvopastoral production system in the Brazilian semiarid region, in order to provide subsidies for future studies on GHG emissions mitigation. The GHG fluxes were monitored over one year, in a buffel grass pasture and in grazed and native Caatinga areas, which are components of a long-term silvopastoral system. The CO2 fluxes ranged from -19.98 to 179.12 mg m-2 h-1 of CO2-C, CH4 fluxes from -76.21 to 113.87 µg m-2 h-1 of CH4-C, N2O fluxes from -1,043.12 to 471.37 µg m-2 h-1 of N2O-N and the soil moisture was the main factor limiting the GHG fluxes. The total emissions converted to CO2-equivalent in the anthropized areas were lower than in the native area (65 % for the buffel grass pasture and 741 % for the grazed Caatinga). Therefore, it is possible to afrm that the GHG soil emissions from grazed areas in the Caatinga biome are not as high as in the native Caatinga, what is an important indication of the environmental sustainability of the evaluated silvopastoral system.

Published: September 2022

ABSTRACT Introduction: There are particularities of chronic kidney disease (CKD) in women and their treatment. The biology of women exposes them to greater risk factors for CKD and both pregnancy and the postpartum period place an additional burden on renal health. Pregnancy complications may cause or worsen CKD. Objective: To explore the experiences of women with CKD undergoing hemodialysis in relation to their reproductive history. Methods: This study consisted of clinical-qualitative design with semi-structured individual interviews and open-ended questions. The sample selection was intentional and according to the theoretical saturation criterion. The data analysis was carried out based on the seven steps of the clinical-qualitative content analysis and validated by Nvivo11. This study was conducted in a public hemodialysis clinic of the Brazilian National Health System. Results: Twelve women undergoing hemodialysis were interviewed. The results from the analysis revealed three categories: 1) Association of pregnancy with CKD; 2) Nebulosity in relation to diagnosis and reproductive history 3) Being a woman undergoing hemodialysis. Conclusion: Our study showed the importance of considering the specificities of CKD in women, suggesting that these issues are important for diagnosis and treatment adherence. Consideration of reproductive life history allows the health of women undergoing hemodialysis to be promoted holistically, including aspects of mental health.

ABSTRACT Introduction: Chronic kidney disease (CKD) has been increasing significantly. There is evidence that a large part of the population does not have enough knowledge on the subject. Objective: To investigate the level of knowledge about CKD in the general population, its risk factors and means of prevention. Methods: We ran a cross-sectional study in the population of Fortaleza, Ceará – Brazil, between 2017 and 2020, with the application of a questionnaire on CKD, risk factors and prevention. Results: we interviewed 735 volunteers, with a mean age of 38 years, of which 55% were female. Only 17.2% correctly responded to the concept of CKD, and 5.8% knew the concept of creatinine. Low water intake was the most cited risk factor by respondents (79.3%). The main risk factors and direct causes of CKD (diabetes and hypertension) were mentioned less frequently (13.2% and 15.1%, respectively). Men were more correct regarding risk factors and ways to prevent CKD. Older respondents answered more correctly the questions about the definition of CKD (n = 22; 28.6%) and creatinine (n = 7; 9.0%). With regards to education there was a statistically significant correlation in all the questions (p < 0.05). Conclusion: There is little knowledge about CKD in the general population. Higher level of education is associated with better knowledge. More health education actions are needed so that the population becomes better acquainted with CKD and, consequently, can adopt more adequate prevention and control measures.

Abstract The objective of this work was to evaluate the physicochemical composition of juices from the 'Bordô' and 'BRS Cora' grapes grown in an organic production system in the Serra do Sudeste region, in Southern Brazil, as well as to compare the cultivar results with data from other producing regions and with the requirements of the Brazilian regulation for whole grape juice. The used grapes came from a commercial vineyard, especifically from the 2016-2017, 2017-2018, and 2018-2019 production cycles. The juices were prepared by the steam drag method and evaluated for their physicochemical composition. The fruit showed suitable values for the parameters necessary for grape juice production. In general, the juices showed bioactive compounds contents similar to those obtained in other regions. The 'Bordô' juices evaluated in the three production cycles showed significant differences for several variables, which were attributed to the influence of weather on grape maturity. The juices of 'BRS Cora' showed high-consistency qualitative results even under the very distinct meteorological conditions of the three production cycles. The juices comply with the current Brazilian regulation for whole grape juice, except for soluble solids, which are severely lowered by the used extraction technique.

Published: September 2022

Abstract The objective of this work was to evaluate the efficiency of the stabilization process of swine manure in storage ponds regarding the presence and antibiotic resistance of pathogenic bacteria. The study was carried out in two trials in ten swine farms located in the municipality of Presidente Castello Branco, in the state of Santa Catarina, Brazil. In the first trial, the efficiency in reducing Escherichia coli (EC), non-E. coli coliforms, and Salmonella sp., as well as the resistance of isolates to antimicrobials, was investigated under recommended handling conditions. Sampling was done at three depths and two times. In the second trial, the concentration of total and fecal coliforms (EC) was evaluated under field handling conditions, when the manure was distributed on the field. Sampling depth does not influence the concentration of EC and Salmonella sp., and isolated bacteria are multi resistant to the evaluated antibiotics. Hydraulic retention time is determinant in reducing the population levels of the indicator agents. The obtained results are indicative that swine manure handling must be carried out according to sanitary standards, in order to minimize the propagation risk and antimicrobial resistance of pathogenic microorganisms.
Fibre reinforcement of railway ballast to reduce track settlement
Authors: Ferro Edgar , Le Pen Louis , Zervos Antonis , Powrie William
Published: September 2022

Most of the world's railways run on ballasted track. However, ballast accumulates differential settlement with trafficking, hence the correct track level must be restored periodically – typically by tamping, which is costly. To reduce the cost of maintenance, several interventions have been proposed with the objective of increasing the interval between tamps by reducing the rate of differential settlement. These include broader ballast gradings, geogrids and under-sleeper pads. A possible alternative is the addition of unbound random fibres to the ballast. Fibres formed from polymer materials, randomly mixed with sands and gravels, have been shown to increase their shear resistance owing to the additional effective confinement associated with the mobilisation of tension in the fibres. However, the effect of the fibres on the permanent strain accumulated under cyclic loading has not been extensively investigated. This paper presents the results of an experimental programme carried out to assess the performance of full-size ballast reinforced with different proportions of polyethylene strip fibres of different lengths and widths. It shows that the addition of a moderate amount (0·6–0·7% of the volume of solids) of narrow fibres has negligible influence on grain packing and can reduce ballast plastic settlement without affecting track resilient stiffness.
Music, Songs, and Dances in Friel’s Plays: A Cultural Perspective
Authors: Kitishat Amal Riyadh
Published: October 2022

The study aims to highlight Brian Friel's employment of non-verbal communication methods to present the major themes in his plays. Friel applied music, song, and dances as nonverbal language. Unlike other dramatists who applied these elements as a way for entertainment, or as marginal theatrical aids. However, this study attempted to reveal how these nonverbal elements played a very important function in expressing the inexpressible. They function at moments when language breaks, and are unable to express the characters’ motives, inner feelings, or even repressed wishes and desires. The plays that are selected for this study are Dancing at Lughnasa (1990), and The Faith Healer (1979). The study will use cultural materialism as a critical approach that helps in shedding light on the historic events that shaped Friel's vision. The study concluded that music, song, and dance were employed as a language that revealed repressed desires, and hidden secrets.

В статье представлены результаты экспериментально-трасологического исследования бронзовых и железных орудий, а также следов пикетажа на красноцветном девонском песчанике, проводившегося с целью определения технологических возможностей тагарских и тесинских металлических инструментов как орудий для создания наскальных изображений способом пикетажа и выявления артефактов, которые могли использоваться для этого. На первом этапе работ выполнен предварительный трасологический анализ петроглифов тагарского времени, а также металлических инструментов и предметов вооружения из фондов Минусинского краеведческого музея им. Н.М. Мартьянова. Отобраны морфологически подходящие орудия, которые могли служить для создания петроглифов, подготовлены экспериментальные эталоны орудий из каменного сырья, а также из металла — различных сплавов на медной основе и низкоуглеродистой стали. На специальном полигоне проведены эксперименты, в процессе которых сформированы образцы пикетажа. Последний этап работ связан с проведением сопоставительного трасологического анализа экспериментальных и археологических данных (следы выбивки петроглифов и следы износа на орудиях-оригиналах). Такой подход обеспечил возможность экстраполяции полученной экспериментальным путем информации на археологические материалы. В коллекциях тагарских и тесинских металлических предметов выявлены инструменты, использовавшиеся при нанесении наскальных изображений в технике пикетажа. Сделан вывод о том, что специализированных орудий для создания петроглифов в скифское время на территории Минусинской котловины не было, для этого применялись инструменты, которые можно назвать универсальными. Определено, что функционально пригодные металлические орудия для пикетажа изготавливали из оловянистой бронзы и низкоуглеродистой стали с термической обработкой. Такие металлические инструменты появляются в регионе в тагарское и тесинское время.

В культурном отношении южнорусские (курские) переселенцы Сибири конца XIX — начала ХХ в. представляли собой качественно иную, по сравнению со многими другими группами русских, общность людей, обладавших выраженными особенностями традиционной культуры, но обычно не проживавших в компактных поселениях. В настоящей работе впервые на основе материалов из Государственного архива Курской обл. рассматривается этнокультурный состав прибывших в Сибирь переселенцев из Курской губ. Раскрываются миграционные настроения крестьян пореформенной деревни юга России, выявляются причины «охоты к перемене мест» и рефлексии местного населения по поводу переезда и этнической идентичности. По документам Государственного архива Томской обл. и полевым материалам автора 2014-2018 гг., относящимся к сибирскому этапу истории курских «южаков», определяется приоритетность вектора общежительства с украинскими переселенцами, что соответствовало сложившейся ситуации на исторической прародине. Это обстоятельство объясняется тем, что в переселенческих процессах начала ХХ в. первостепенную роль играли выходцы с территорий «дикого поля», русско-украинского пограничья. В южных районах Курской губ. на момент переселений в Сибирь проживали русские старообрядцы, южнорусские, белорусы, украинцы (малороссы), русские казаки, черкасы (украинские казаки), причем последние предпочитали жить в разных частях даже одного селения и пр. Данные архивов и результаты проводившихся на территориях Анжеро-Судженского р-на Кемеровской обл., а также Топчихинского и Кулундинского р-нов Алтайского края экспедиционных исследований свидетельствуют о ситуативной идентичности южных русских, которая нередко выражалась во внешних формах — смене окончаний фамилий с -ко или -к на -ов и обратном возвращении при изменении планов переселения. Сделан вывод о том, что этнокультурное многообразие выходцев из Курской губ., их склонность к ситуативной идентичности, а также смешанные браки с русскими старожилами и украинцами сыграли решающую роль в формировании сибирских (локальных) вариантов культуры южнорусских переселенцев.

Diagnosis of breast cancer and the determination of cancer type are essential information for cancer research in monitoring and managing the disease. Artificial intelligence techniques developed in recent years have led to many developments in medicine, as any information about the patient has become more valuable. Especially, artificial intelligence methods used in the detection and classification of cancer tissues directly assist physicians and contribute to the management of the treatment process. This study aims to classify breast tissues with ten different tissue characteristics utilizing the breast tissue data set, which has 106 electrical impedance spectroscopies taken from 64 patients in the UCI Machine Learning Repository database. Various machine learning algorithms such as k-nearest neighbors, support vector machine, decision tree, self-organizing fuzzy logic, and convolutional neural networks are used to classify these tissues with the accuracy of 81%, 78%, 82%, 92%, and 96%, respectively. This study demonstrated the benefit of the usage of convolutional neural networks in cancer detection and tissue classification. Compared to traditional methods, convolutional neural networks provided a more reliable and better results.

Published: September 2022

The small volume of microstrip antennas has low production costs and easy production, which has accelerated the work in this area. The disadvantages are narrow bandwidth and low gain. In wireless communication, antennas with low return loss and high bandwidth are required. The bandwidth and power gain of the microstrip patch antennas should be increased optimally. This article presents the design of the broadband microstrip patch antenna operating in the ISM 2.4 GHz band (2400-2485 MHz). The study includes three-dimensional antenna model, simulation phase and fabrication / measurement phase. For the low cost of the antenna, FR-4 with the relative dielectric constant 4.3 and the loss tangent tan 0.02 is preferred as the substrate material. Dielectric material thickness is determined as 1.6 mm. The length of the feed line and the dimensions of the rectangular patch were found by mathematical calculations with the transmission line model. There are slots on the antenna, which is a very simple method in order to improve the bandwidth, gain and directivity parameters of the antenna. In the article, four different designs are presented, the results are compared and the proposed antenna has 979 MHz bandwidth and 2.68 dBi directivity gain at -10 dB at the resonance frequency of 2.316 GHz. The changes made in the antenna design have improved the results such as gain and bandwidth compared to the conventional microstrip patch antenna. The proposed antenna is suitable for use in mobile communication.

BACKGROUND: In addition to the neurological complications affecting people infected with COVID-19, cognitive impairment symptoms and symptoms of anxiety and depression remain a frequent cause of complaints. The specificity of cognitive impairment in patients with COVID-19 is still poorly understood.
AIM: An exploratory study of factors that may be associated with cognitive decline during the COVID-19 pandemic.
METHODS: The cross-sectional multicentre observational study was conducted in a polyclinic unit in Saint Petersburg and in the regions of the North-Western Federal Region. During the study, socio-demographic parameters and information about the somatic condition of patients who applied for primary health care was collected. Emotional and cognitive state were investigated using the Hospital Anxiety and Depression Scale (HADS) and Montreal Cognitive Assessment (MoCA). Mathematical and statistical data processing was carried out using SPSS and RStudio statistical programs.
RESULTS: The study included 515 participants, 60% (n=310) of which were women. The sample was divided into those who did (28.5%, n=147) and did not (71.4%, n=368) complain of cognitive decline. Patients with complaints of cognitive decline were significantly older, had lower levels of education and higher levels of depression and anxiety according to HADS (p 0.05). Patients with complaints of cognitive decline underwent the MoCA test (24.3%, n=125). The median MoCA test scores were within the normal range (Median=27, Q1=25, Q3=28), and cognitive decline (MoCA less than 26 points) was detected in 40% (n=50) of patients with complaints of cognitive decline. No significant correlations were found between the MoCA scores and the levels of anxiety and depression according to the HADS (p 0.05). Patients with mild severity of the COVID-19 course were more successful with MoCA subtests than patients with moderate and severe courses.
CONCLUSION: We found no linear association between objective cognitive deficit and the affective state of respondents. Patients subjective complaints about cognitive dysfunction were mostly caused by their emotional state than an objective decrease of their cognitive functions. Therefore, in case of subjective complaints on cognitive decline, it is necessary to assess not only the cognitive but also the affective state of the patient. The severity of the COVID-19 course affects the functions of the cognitive sphere, including attention, regulatory functions and speech fluency. Mild and moderate severity of the COVID-19 correlates with clinically determined depression. The absence of this relationship with the severe course of the disease is probably explained by the significant somatic decompensation of patients.
Revisiting Social Stigma in Non-suicidal Self-injury: A Narrative Review
Authors: Banerjee Debanjan , Meheli Saha
Published: September 2022

Non-suicidal self-injury (NSSI) is highly prevalent in our community. Yet, there is a significant discrepancy between the number of individuals engaging in NSSI and those who seek treatment for NSSI. This discrepancy can be due to the high social stigma associated with the behavior. The impact of NSSI stigma is significant and can impair the quality of life in the individuals engaging in NSSI, delay help-seeking, reduce access to mental health care and further fuel misinformation. Even though the symptomatology, risks, and demographics of NSSI have received attention in terms of research, there is limited literature on NSSI stigma and its consequences. With that background set, this review provides a birds-eye view of the different levels of stigma in NSSI (public, self, and health care), associated discrimination, the various aspects of such stigmatization (NSSI-related language, physical scarring, misinformation, the media), and, finally, the collaborative clinical-outreach interventions for mitigating NSSI-associated social stigma. If NSSI is indeed recognized as a clinical disorder, future research would need to focus on these constructs of stigma and treat them with the same importance as the one given to clinical studies of intervention and symptomatology in NSSI.
