ABSTRACT: This study aimed to establish the prevalence of animals persistently infected (PI) with bovine viral diarrhea virus (BVDV) in dairy farms at Parana State, Brazil. Samples were collected from 6,465 female Holstein Friesian Dairy Cattle, including animals less than two years old, females over two years old who had not given birth at the farm, and mothers of calves diagnosed as persistently infected. The cattle came from 40 dairy herds distributed in 10 municipalities in the State of Paraná. The samples were obtained from May 2015 to August 2018. The diagnosis of PI animals was made with an antigen-capture ELISA test. We detected PI animals in fifteen herds sampled (37.5%), ranging from one to sixteen animals per herd. The prevalence in Parana State’s municipalities was 1.78%, ranging from 0.3 to 8.9% at positive herds. The analysis of the individual herds shows significant dissemination of the BVDV in Parana’s municipalities, including endemic areas. With this, we highlight the need for measures to raise awareness among producers about the existence and importance of bovine viral diarrhea (BVD) in dairy herds, reinforcing the PI animals’ role in disease epidemiology and the economic impact caused by the maintenance of these farm animals.

ABSTRACT: The aim of this study was to verify the applicability and accuracy of B-mode ultrasonography in detecting malignancy in dog cutaneous neoplasms. Forty-two neoplasms (12 benign and 30 malignant) of mesenchymal, round cells, epithelial and melanocytic origins from 24 dogs of different breeds and ages were included. The ultrasound evaluation was performed with a linear multi-frequency transducer (7.0 to 12MHz), with frequency dependent on the mass dimension. Ultrasonographic characteristics of echogenicity (hypo/hyperechogenic), echotexture (homogeneous/heterogeneous), regularity, invasiveness in adjacent tissues were classified. Dimensions were also measured to calculate the depth/width ratio. Neoplasms were classified as malignant or benign after cytological and/or histopathological analysis and the results were associated with ultrasound characteristics. There was a significant association (P<0.05) between malignancy and echogenicity, echotexture and invasiveness in adjacent tissues, so that 84.6% of hypoechogenic neoplasms, 76.9% of heterogeneous masses and 88.2% of invasive neoplasms were classified as malignant. However, for all these associations, moderate predictive values were obtained, which may be due to the small experimental number included in this study. Therefore, although it has been observed that hypoechogenic, heterogeneous and invasive neoplasms were more prone to malignancy, these findings should be used with caution until new studies are developed with a greater number and variety of cutaneous neoplasms in dogs.

ABSTRACT: Canine atopic dermatitis (CAD) is a pruritic, chronic inflammatory disease, recurrent and genetically predisposed, which is the second most frequent allergic skin disorder, and ranks second among all the causes of pruritus in dogs worldwide. Given the absence of data on the occurrence of CAD in the northern region of Brazil, the aim of the current study was to conduct a survey to define the prevalence of canine atopic dermatitis attended at the Dermatology Department of the Mário Dias Teixeira Veterinary Hospital of the “Universidade Federal Rural da Amazônia” (HOVET-UFRA). To determine the prevalence of CAD, a retrospective survey was carried out of clinical records and results of dermatological examinations conducted at the Dermatology Department of HOVET-UFRA Belém, Pará from October 2018 to October 2019. During this period, 456 dogs were examined, of which 25.65% (117) were diagnosed with atopic dermatitis. Among the animals diagnosed, 62.4% (73) were females and 51.7% (29) were of the Shih-tzu breed. This level of atopic dermatitis is considered high. There are still no exact data on the incidence and prevalence of this dermatopathy, with described occurrence ranging from 3 to 15% of the canine population, a geographical relationship may be present. Although a sex-related predisposition has not been proven, a higher incidence of atopy in females is described, which indicated this may be the case. The most commonly diagnosed dogs in this study were the Shih-tzu breed. It is suspected that the regional popularity of some breeds, or the different genetic backgrounds in different geographical areas, may affect the predominance of CAD in some breeds. The results of the present study demonstrate the need for more research on the prevalence of canine atopic dermatitis, and better means of characterizing the population of atopic dogs in the region, so that it is possible to obtain a reliable epidemiological profile.
A Importância da Explicitação da Correspondência Um para Muitos na Resolução de Problemas de Estrutura Multiplicativa
Authors: Spinillo Alina Galvão , Lautert Síntria Labres , Santos Ernani Martins dos
Published: April 2021

Resumo Diversos aspectos influenciam a resolução de problemas multiplicativos por crianças, como as características numéricas das tarefas e os suportes de representação disponibilizados durante os procedimentos de resolução. O presente estudo investiga o papel desempenhado por um outro aspecto que é constitutivo do raciocínio multiplicativo: a correspondência um para muitos. Esta correspondência pode estar implícita ou explicitamente mencionada no enunciado dos problemas. Neste estudo examinou-se a possibilidade de que o nível de explicitação da relação um para muitos seria fator importante na resolução de problemas multiplicativos, e que quanto mais explícitas fossem essas relações, melhor seria o desempenho das crianças. Para isso, problemas de multiplicação e de divisão foram solucionados por crianças do 3° e 5° ano do Ensino Fundamental. Os problemas apresentavam diferentes níveis de explicitação da correspondência uma para muitos. Observou-se que o desempenho era melhor nos problemas em que a correspondência uma para muitos era explicitamente mencionada no enunciado do que em problemas em que esta relação estava implícita. Isso foi observado em ambos os anos escolares. Os resultados evidenciam o papel facilitador que a explicitação da correspondência um para muitos desempenha na resolução de problemas de estrutura multiplicativa. Implicações teóricas e educacionaissão discutidas.

Published: April 2021

RESUMO Objetivo: objetiva-se, com este artigo, introduzir algumas contribuições do conceito de conatus para a pesquisa sobre sucessão em empresas familiares. Métodos: a sucessão tem sido uma das temáticas mais discutidas no campo de estudos sobre empresas familiares. O presente trabalho, de natureza teórica, procura agregar contribuições a essa literatura, compreendendo a dinâmica da sucessão através da exploração do quadro teórico-conceitual desenvolvido por Bourdieu. Resultados: o conatus pode ser interpretado como um projeto cultivado pela família e que deve ser perpetuado para e pelas futuras gerações. Assim, a compreensão da sucessão a partir deste conceito permite, dentre outras possibilidades, apreender as particularidades da transmissão do projeto construído pelo fundador para as gerações sucessoras da família, que seriam os responsáveis por perpetuar ou não o conatus. Conclusão: o conceito de conatus, posicionado no âmbito do quadro teórico-analítico mais amplo trabalhado por Bourdieu, oferece alternativas para a compreensão e a explicação da sucessão em empresas familiares de uma forma mais consistente e aproximada da realidade observada nesses processos, fornecendo fundamentos que podem contribuir para a elucidação de perspectivas ainda pouco exploradas na literatura sobre esse tipo de organização.

ABSTRACT The use of organic fertilizers facilitates the production of plant species compared to industrial fertilizers, with a remarkable contribution to soil and water conservation through soil structuring. Vetiver grass (Chrysopogon zizanioides (L.) Roberty) is widely used in soil bioengineering projects to stabilize slopes, increasing the resistance of the soil to shear strength. The objective of this study was to evaluate the effect of the development of vetiver grass at different doses of organic fertilizer on soil stabilization. An experimental test was carried out in a greenhouse, in pots, using the following doses of organic fertilizer: T0-0 g (control); T1-135 g; T2-270 g and T3-405 g of organic fertilizer. Shoot Dry Matter (SDM), Root Dry Matter (RDM), Root Length (RL), Number of Tillers per Plant (NT) and Plant Height (PH) were evaluated. The collected data were submitted to regression analysis at 5% probability. The analysed variables showed increasing values as greater amounts of organic fertilizer, leading to an increase in soil nutrient availability and, consequently, to improved plant development.

ABSTRACT Information on the different species that compose a weed community is essential for plant protection managements in production systems, which should include not only flora identification and diversity assessments, but morphological and ecophysiological aspects that can to show the potential effect of the agrosystem and guide the conduction of weed control strategies. Therefore, the objective of this work was to conduct a floristic and phytosociological surveying to identify the grouping patterns of weed populations in vineyards in the Petrolina-Juazeiro irrigated perimeter, in the Sub-Mid São Francisco River Valley, Brazil. The absolute and relative values of weed frequency, density, abundance, importance value index, population distribution level, and similarity between areas were evaluated in five properties. A high diversity of species of the families Poaceae, Malvaceae, and Asteraceae were found. The most important species found were Commelina benghalensis, Euphorbia hirta, and Cyperus aggregatus. The distribution of populations was mainly in aggregate and highly aggregate forms.

Published: April 2021

ABSTRACT Soils are highly variable across landscapes, which can be assessed and characterized according to scale, as well as fractal and multifractal concepts of scale. Thus, the objective of this study was to analyze the multifractality of the penetration resistance (PR) of vertical profiles from different slope forms (concave and convex). The experimental plot incorporated 44.75 ha, and the PR was measured at 70 sampling points in the 0-0.6 m layer, distributed in concave (Type A: 38 sampling points) and convex pedoforms (Type B: 32 sampling points). Data analysis was performed using the PR value (every 0.01 m depth) for each of the sampling points (PRmean), and their respective maximum (Prmaximun) and minimum (PRminimum) values. Multifractal analysis was performed to assess the changes in the structure, heterogeneity, and uniformity of the vertical profiles according to the scale, characterizing the partition function, generalized dimension, and singularity spectrum. The multifractal parameters of the generalized dimension and singularity spectrum demonstrated greater homogeneity and uniformity in the vertical PR profiles of pedoform B (convex) compared to those of pedoform A (concave). The minimum PR values in pedoform A (PRminimum) showed the greatest scale heterogeneity, indicating that in terms of soil management, it is more relevant to monitor the minimum values than the maximum values. The fractal analysis allowed us to describe the heterogeneity of the data on scales not evaluated by conventional analysis methods, with high potential for use in precision agriculture and the delimitation of specific management zones.

Published: April 2021

ABSTRACT Geometridae is one of the most diverse Lepidoptera families; however, little information about Geometridae species is found, even regarding their distribution and basic biology, which are in general restricted to type locality. Lists of species and their host plants are not found for the Semiarid region of the Northeast of Brazil. The present note reports the occurrence of caterpillars of the species Numia terebintharia Guenée consuming leaves of evergreen trees of Ziziphus joazeiro Mart. in a site with xerophilous deciduous Caatinga vegetation in that region. Some trees had approximately 90% of their leaves with injuries. This is the first record of N. terebintharia caterpillars occurring in Brazil and the first record of Z. joazeiro as their host plant.

ABSTRACT The objective of this study was to characterize, through faunistic indices, the populations of fruit flies in the Brejo Paraibano microregion and analyze whether these populations are similar to one another. The study was conducted in eight municipalities located in the Agreste Paraibano mesoregion and Brejo Paraibano microregion, Paraíba state, Brazil, where two rural properties of each municipality were selected, georeferenced and identified according to the diversity criterion of fruit species. Each municipality was assumed to have a population of fruit flies with its own characteristics, determined by the faunistic indices of frequency, constancy, dominance, Shannon-Wiener and Margalef diversity indices, as well as evenness. 3.159 specimens of fruit flies were captured, of which 85.57% belonged to the genus Anastrepha and 14.43% to the genus Ceratitis. 11 species of fruit flies were captured in the traps. Anastrepha fraterculus was the most frequent, dominant and constant species, being present in all locations; followed by A. obliqua, A. sororcula and Ceratitis capitata. The studied municipalities have a similarity of 54%, which indicates a high similarity between the areas. Most species captured in the present study occur at low population frequency.

Published: April 2021

O artigo trata de experiências de familiares no cuidado de crianças com Síndrome Congênita do Zika Vírus (SCZV) e objetiva analisar o impacto do nascimento do bebê com malformação, as reorganizações psíquicas parentais e seus desdobramentos no cuidado, particularmente o materno. Foi adotada abordagem psicossocial, de base psicanalítica, em diálogo com estudos do campo da Saúde Coletiva. São analisadas narrativas de familiares de 32 encontros grupais realizados em ambulatório de um Instituto de Pesquisa no Rio de Janeiro, Brasil, em 2017. O processo de análise pautou-se na psicossociologia e na análise temática. Angústias, incertezas e sobrecarga marcaram a experiência parental. As dificuldades de desenvolvimento do bebê levaram os pais a um modo singular de lidar com seus filhos e à construção de caminhos de esperança e resistência. O protagonismo materno tornou-se a base para lutas nas áreas social, de saúde e educação.
Vários tons de “não”: relatos de profissionais da Atenção Básica na assistência de lésbicas, gays, bissexuais, travestis e transexuais (LGBTT)

Published: April 2021

As populações de lésbicas, gays, bissexuais, travestis e transexuais (LGBTT) vivenciam obstáculos no acesso e na assistência ofertada pelos serviços da Atenção Básica. Neste estudo, buscamos analisar relatos de profissionais na assistência dessas populações na Estratégia Saúde da Família (ESF). Tratou-se de uma pesquisa qualitativa realizada por meio de relatos orais. Participaram 32 profissionais que atuavam em uma Unidade Básica de Saúde (UBS) em Teresina, Piauí, Brasil. A análise foi pautada em três dimensões – reconhecimento, redistribuição e representação – e mostrou que é preciso interligar, dentro de um mesmo princípio de justiça, o espaço do reconhecimento da diversidade sexual e de gênero (campo cultural), o espaço das desigualdades atreladas à exploração e redistribuição de recursos (campo organizacional) e o espaço de representação e participação das populações LGBTT (campo político e social), na lógica circular dos serviços de saúde.

Este texto está voltado à discussão da Responsabilidade Social Universitária (RSU). Considerando a influência de fatos históricos na constituição do conceito, o estudo tem por base uma pesquisa bibliográfica de caráter histórico. A discussão contempla a composição do conceito ao longo da trajetória da universidade, os fatos institucionais e a base legal no caso brasileiro. Também são discutidas as múltiplas definições de responsabilidade social presentes em estudos acadêmicos e a complexidade envolvida na adoção do conceito no âmbito das organizações universitárias. Como contribuições o estudo apresenta a sistematização contextualizada das ideias sobre a RSU, considerando os fatos relacionados a constituição do conceito, e que a temática representa um avanço nas formas de controle e mensuração da gestão das universidades. As conclusões do estudo apontam para a multidisciplinaridade do tema, considerando para tal as raízes implícitas na razão de ser da universidade e que a implantação de ações de RSU vai além de atribuições específicas do grupo responsável pela gestão deste tipo organizacional.

Published: April 2021

Neste artigo analisamos motivações e problemas institucionais que fazem com que mulheres em cursos de Engenharia e Tecnologias desistam ou permaneçam na graduação. Investigamos relatos de estudantes que vivenciaram a graduação entre 2012 e 2019 na Universidade Tecnológica Federal do Paraná, campus Guarapuava, Brasil. Esse locus é entendido como microcosmo de divisões de gênero na formação acadêmica que são mais amplos e que revelam assimetrias de acesso e de permanência de mulheres no sistema universitário brasileiro. Para isso, trabalhamos com uma abordagem que aproxima Estudos de Gênero e Ciências, pensando relações entre homens e mulheres no âmbito das relações de poder e usos sociais de instituições acadêmicas. Como resultado, acompanhamos dados de matrículas, permanências e desistências por gênero na instituição. O estudo aponta para a necessidade de ações instituições de combate à discriminação de gênero, e ao desenvolvimento e estratégias de permanência de estudantes mulheres nos cursos de graduação.

Authors: Heiderscheidt Francisca Goedert , Forcellini Fernando Antônio
Published: April 2021

A avaliação, sobretudo da qualidade da educação, é essencial para que a sociedade saiba o que está sendo produzido nas universidades. Portanto, a busca pela qualidade na educação tem sido objeto de estudo de diversas áreas de conhecimento, e, pode-se dizer que a área de avaliação institucional tem ganhado força nos últimos tempos, tendo em vista os desafios impostos que envolvem, acima de tudo, o diagnóstico de quão bem estão as instituições de ensino. Por meio da avaliação institucional é mapeada a realidade da instituição, que é o alicerce para proposições de ações de melhoria. Assim, esse artigo tem como objetivo identificar o que as instituições de ensino superior consideram valor no processo de avaliação. Essa pesquisa exploratória analisa o valor nos estudos sobre avaliação institucional e aponta a inovação como caminho determinante. A inovação nesse processo se torna crucial e a gestão da transição é uma lente que auxilia na identificação dos atores envolvidos, bem como na concretização da implementação dessa transição sociotécnica, com foco na mudança social e cultural.

Published: April 2021

A evasão é um tema de interesse mundial na área da educação, contudo o entendimento atual sobre o fenômeno é ainda insuficiente, sobretudo quando o objetivo é avaliar políticas efetivas de evasão. Neste artigo o percentual anual de evasão da Unesp é avaliado com base na adoção da política de reserva de vagas. Existem três possibilidades de ingresso - sistema universal (SU), quota por ter estudado em escola pública (EP) e quota por ser PPI (pretos, pardos, indígenas). Os dados foram segmentados por curso e ano de ingresso. A Unesp tem campus em 24 cidades, que reúnem 34 unidades e abrigam 136 diferentes cursos de Graduação. O ingresso para estes cursos é realizado por meio de vestibular com 186 diferentes opções em 63 carreiras. Uma comparação das taxas de evasão permite observar que elas podem depender do modo de ingresso, mas isso ocorre de forma variada ao longo do tempo e depende da área do curso, não sendo significativo. Verificou-se um decréscimo consistente da taxa de evasão global e por categoria de ingresso.
Financiamento das universidades líderes nos rankings internacionais, um caminho para as universidades públicas brasileiras?
Authors: Tumenas Felipe
Published: April 2021

As universidades públicas brasileiras enfrentam desafios no seu financiamento. Cortes e contingenciamentos vêm ao mesmo tempo de uma maior cobrança por pesquisas, internacionalização e desempenho nos rankings internacionais. Propostas para a solução desse dilema se baseiam em ideias isoladas de financiamento de universidades internacionais. Este artigo levanta as principais fontes de receitas das universidades líderes nos rankings internacionais. Através da análise dos relatórios anuais do período de 2014 a 2018, é possível ver que não existe um padrão único de financiamento nessas universidades. Ademais, a fonte de receita com maior relevância dessas universidades é pesquisa e grande parte da receita de pesquisa vem de financiamento público, o que indica que qualquer solução para a questão do financiamento das universidades deve incluir uma participação ativa do estado e que a busca de possíveis caminhos de financiamento em instituições internacionais deve ser feita com extrema cautela.

Authors: Garcia Gracielle Pereira Aires , Marziale Maria Helena Palucci
Published: April 2021

ABSTRACT Objective: To correlate the indicators of job satisfaction, factors of occupational stress and professional exhaustion among nurse managers and care nurses in Primary Health Care. Method: Descriptive, exploratory field study conducted in 45 units of Primary Health Care in Brazil. The following instruments were used for data collection: Sociodemographic Questionnaire, Work Stress Scale, Burnout Characterization Scale and the Job Satisfaction Questionnaire - S20/23. Results: Participation of 122 nurses (47.5% managers; 62.5% care), 32% had considerable stress levels, indicators of emotional exhaustion, dehumanization and disappointment at work in moderate to high levels. The indicator of satisfaction with the physical work environment did not show significance with variables of professional exhaustion, while satisfaction with hierarchical relations and intrinsic job satisfaction are strongly correlated. Conclusion: There is an association between organizational problems and working conditions that hinder nurses' work. Regardless of the position, job satisfaction is inversely proportional to burnout.

ABSTRACT Objective: To verify the relationship between authentic leadership of nurses and structural empowerment. Method: This is a systematic review carried out at the Virtual Health Library on the Journal Portal of the Coordination for the Improvement of Higher Education Personnel, Online System for the Search and Analysis of Medical Literature, Scientific Electronic Library Online and Science Direct/Embase, and consulted until April 2019. Studies with nurses, evidencing the relationship between authentic leadership and structural empowerment, published between 2012 and 2018 in Brazilian Portuguese, English or Spanish were included. Results: Five studies were included, with variables other than structural empowerment: job satisfaction, burnout, bulling, mental health, performance, social capital, working environment, nurse retention, and quality of care. Authentic leadership showed a positive relationship with structural empowerment, improving engagement and job satisfaction, reducing burnout and increasing quality of care. Conclusion: Health institutions, in addition to Canada, where researchers on this topic are located, can invest in authentic leadership to improve structural empowerment by providing greater commitment from nurses, increased job satisfaction and quality of care provided.

Published: April 2021

ABSTRACT Objective: To analyze the scientific evidence available on the sexual and reproductive health of riverine communities. Method: Integrative review, conducted on the databases LILACS, MEDLINE; WEB OF SCIENCE and SCOPUS, including publications in Portuguese, English or Spanish, without an initial time limit and published until 2018. Results: 11 studies were selected. The studies included are from the period 1993-2017. The results originated four analytical categories: sexual component, which gathered findings about sexually transmitted infections; reproductive component, which included family planning/fertility control, abortion and problems with pregnancy; environmental component, which presented issues with environmental contaminants and its reproductive implications; and the sociocultural component, which discussed gender, beliefs and social indicators. Conclusion: In this review, studies with a quantitative approach, from a female point of view and a biological perspective predominated. No study investigated the meanings and representations of SRH for the riverine communities. In addition, the findings show little evidence of thoughts and practices of people living in riverine communities regarding SRH issues, providing limited evidence.
Time-varying Uncertainty of the Federal Reserve's Output Gap Estimate
Authors: Berge Travis J.
Published: April 2021

A factor stochastic volatility model estimates the common component to estimates of the output gap produced by the staff of the Federal Reserve, its time-varying volatility, and time-varying, horizon-specific forecast uncertainty. Output gap estimates are very uncertain, even well after the fact, especially at business cycle turning points. However, the common component of the output gap estimates is clearly procyclical, and innovations to the common factor produce persistent positive effects on economic activity. Output gaps estimated by the Congressional Budget Office have very similar properties. Increased macroeconomic uncertainty, as measured by the common factor's volatility, leads to persistent negative responses in economic variables.
COVID-19 and the Nervous System

Published: April 2021

Neurologic complications are a significant cause of morbidity and mortality in the COVID-19 pandemic. Besides respiratory disease, neurological manifestations such as headache, dizziness, hyposmia, hypogeusia, acute cerebrovascular disease, encephalopathy, encephalitis are common. These complications may result from various mechanisms; virus-induced hyperinflammation and hypercoagulable states, a direct viral effect on the central nervous system, and post-infectious autoimmunity. We must keep in mind diagnosing SARS-CoV-2 infection when patients present with specific or non-specific neurological symptoms during the pandemic.
KIRGIZ TÜRKÇESİNDEKİ MOĞOLCA ALINTI KELİMELER (-A- Maddesi)
Authors: KALİEVA Kenjegul
Published: April 2021

Tarih boyunca Kırgızlar bulundukları coğrafyalardaki farklı kavimlerle siyasî, ekonomik, kültürel ve dilsel olarak etkileşim içinde olmuşlardır. Bu tür etkileşimler, Kırgız Türkçesinin sözvarlığının zenginleşmesini sağlamıştır. Kırgız Türkçesinin söz varlığında Çinceden, Sanskritçeden, Moğolcadan, Arapçadan, Farsçadan ve Rusçadan çok sayıda alıntı sözcükler bulunmaktadır. Günümüze dek bu alıntılarla ilgili genel bir tanıtım çerçevesinde makaleler, sözlükler, kitap bölümleri yazılmıştır. Ancak Kırgız Türkçesinde Moğolcadan alıntı sözcükler üzerine yapılan araştırmalar azdır. Tarihî kaynaklara bakıldığında Kırgız Türkleri ile Moğolların münasebeti farklı asırlarda gerçekleşmiştir ve bundan dolayı Moğolca alıntı sözcükler, Kırgız Türkçesinin ağızlarında aynı şekilde kullanılmamaktadır. 20.yüzyılda gerçekleştirilen Kırgız Türkçesinin ağızlarına yönelik çalışmalar incelendiğinde, Kuzey ağızlarında Moğolca alıntı sözcüklere daha sık rastlandığını görülmektedir. Bazı Moğolca alıntı sözcüklerin aslına yakın biçimi Güney ağızlarında da tespit edilmiştir. Kırgız Türkçesinde Moğolcadan alıntı sözcükleri şu şekilde sınıflandırmak mümkündür: akrabalık adları, beden ile ilgili terimler, hayvanların yaşlarına, dış görüntülerine göre verilen adlar, tıbbî terimler, sıfatlar, eylemler vs. Moğolcadan alıntılarla ilgili yer-su adları üzerinde yapılan araştırmalar daha yaygındır. Bundan dolayı Kırgız Türkçesindeki Moğolca alıntı kelimeler üzerinde bir çalışma amaçlanmıştır. Bu makalede, Kırgız Türkçesindeki –A- harfiyle başlayan Moğolca alıntı kelimeler üzerinde durulacaktır. Bu Moğolca alıntı kelimeler Yudahin’in 1965 yılında yayınladığı Kırgızca-Rusça sözlüğünden ve Kırgız Türkçesinin ağız çalışmalarından taranmıştır. Tespit edilen alıntı kelimeler komşu Türk dilleriyle (Kazakça, Özbekçe ve Yeni Uygurca) ve bazı durumlarda da diğer Türk dilleriyle karşılaştırılmıştır.
Cruciform Signs Decorating Paleolithic Bone Artifacts from Cherno-Ozerye II, the Middle Irtysh Area
Authors: Schmidt A. V.
Published: April 2021

This study describes decorated bone artifacts from the Final Paleolithic or Epipaleolithic site of Cherno-Ozerye II in the Middle Irtysh area—a fragment of a bone dagger hilt found during the 1971 excavations, and fragments of bone “needle cases” found in 2019. An interpretation of the meaning of cruciform signs on the artifacts is suggested with reference to technology and form. Parallels from Ural and Eastern European sites are discussed. It is concluded that in terms of technology, morphology, and “syntax”, the signs are stable markers of certain hunter-gatherer groups. Their specificity and possible meaning suggest that the Middle Irtysh area was a contact zone between Western (Ural) and Eastern Siberian groups of Paleolithic foragers.

Authors: Sirina A. A.
Published: April 2021

On the basis of museum collections, field records, photographic and video recordings made in the 20th to early 21st centuries, a reindeer riding saddle with flaps, typical of the eastern Evenki, is analyzed. Its construction and types of fastening are described in detail. Manufacturing technologies are discussed in the context of modern theories of material culture as adaptations to changing natural and social environments under a mobile lifestyle. The key principles underlying mobility in the taiga include the use of a wide range of materials and techniques, modularity (assembled construction with mutually complementary and interchangeable parts), a technological cycle adapted to natural rhythms, adherence to traditional knowledge, the use of artificial materials along with products of nature (since the mid-1900s), etc. In the nomadic culture, the esthetics of an artifact are intrinsically related to function, harmony, and social significance. The manufacture of reindeer riding saddles has been affected by changes in the social structure of nomadic groups.
Comparison and optimisation of fast array-based ultrasound testing

Phased array ultrasonic testing (PAUT) is now a widely used technique in industry for non-destructive testing. Arrays offer an intuitive view of the interior of a component from which geometric features and defects can be observed. Arrays also offer detailed information about the nature
and extent of any defects. In recent years, full matrix capture (FMC) and the total focusing method (TFM) have attracted significant interest due to the high resolution of the images possible throughout an inspection volume. Due to the requirement of transmitting on each element separately,
full matrix capture-based imaging techniques limit the maximum frame rate and scan speed achievable. Recently, to increase the speed of data acquisition, new techniques such as plane wave imaging (PWI) and virtual source aperture (VSA) have been introduced. They allow a significant reduction
in the number of firings to be achieved without contributing to any major loss of image quality. In this paper, an in-depth comparison of these techniques using a hybrid linear system model and the analysis of experimental data is performed to assess the image quality of these emerging imaging
algorithms and hence identify the optimal parameters for faster imaging.

On 8 August 2017, an Ms 7.0 earthquake struck the Jiuzhaigou town, Sichuan Province, China, rupturing an unmapped fault, which is adjacent to the Maqu seismic gap in the Min Shan uplift zone in the easternmost part of the Bayan Har block. Having summarized the previous studies on the source of this earthquake, we confirmed the rupture model by jointly inverting the teleseismic P-wave and SH-wave data, Interferometric Synthetic Aperture Radar line-of-sight displacement data, and the near-field seismic and strong-motion data, a most complete dataset until now. The confirmation showed that a scalar seismic moment of 6.6×1018  N·m was released (corresponding to a moment magnitude of Mw 6.5), and 95% of the release occurred in the first 10 s. The slip area was composed of two asperities, with a horizontal extension of ∼20  km and a depth range of ∼2–15  km. A bilateral extending occurred at shallow depths, but the rupturing upward from deep depth dominated in the early time. The rupture process was found generally featuring the slip-pulse mode, which was related to the weak prestress condition. The aftershocks almost took place in gaps of the mainshock slip because of the coulomb stress change. Combining the aftershock relocations, aftershock focal mechanism solutions, and our confirmed rupture model, we suggest that the seismogenic fault was a northward extension of the mapped Huya fault. The occurrence of this earthquake made the Maqu seismic gap at a higher level of seismic risk, in addition to the moderate to high strain accumulation on the easternmost tip of the Kunlun fault system and the weak lower crust below.
Experimental Evidence of Velocity-Weakening Friction during Ice Slip over Frozen Till: Implications for Basal Seismicity in Fast Moving, Soft-Bed Glaciers and Ice Streams

Published: April 2021

Observations of glacier slip over till beds, across a range of spatial and temporal scales, show abundant seismicity ranging from Mw∼−2 microearthquakes and tremor (submeter asperities and millisecond duration) to Mw∼7 slow-slip events (∼50  km rupture lengths and ∼30  min durations). A complete understanding of the mechanisms capable of producing seismic signals in these environments represents a strong constraint on bed conditions. In particular, there is a lack of experimental confirmation of velocity-weakening behavior of ice slipping on till, where friction decreases with increasing velocity—a necessity for nucleating seismic slip. To measure the frictional strength and stability of ice sliding against till, we performed a series of double-direct-shear experiments at controlled temperatures slightly above and below the ice melting point. Our results confirm velocity-strengthening ice–till slip at melting temperatures, as has been found in the few previous studies. We provide best-fit rate-and-state friction parameters and their standard deviations from averaging 13 experiments at equivalent conditions. We find evidence of similar velocity-strengthening behavior with 50% by volume debris-laden ice slid against till under the same conditions. In contrast, velocity-weakening and linear time-dependent healing of ice–till slip is present at temperatures slightly below the melting point, providing an experimentally supported mechanism for subglacial seismicity on soft-beds. The stability parameter (a−b) decreases with slip velocity, and evolution occurs over large (mm scale) displacements, suggesting that shear heating and melt buildup is responsible for the weakening. These measurements provide insight into subglacial stiffness in which seismicity of this type might be expected. We discuss glaciological circumstances pointing to potential field targets in which to test this frozen seismic asperity hypothesis.
Organización altitudinal de las formas kársticas del Macizo Occidental de los Picos de Europa (Montañas Cantábricas) y su interrelación con el glaciarismo cuaternario y la morfodinámica periglaciar

Published: April 2021

En los conjuntos montañosos con un desarrollo altitudinal importante, la tipología de las formas kársticas presentes, así como la intensidad de la disolución kárstica, varían en función de la altitud (además de los consabidos factores estructurales). Sin embargo, apenas existen estudios relativos a esta cuestión. Este trabajo, basado fundamentalmente en la realización de un trabajo de campo sistemático y exhaustivo que se ha prolongado durante varios años en el Macizo Occidental de los Picos de Europa, se centra en el estudio del modelado kárstico de este macizo cantábrico de alta montaña. En él se han identificado los procesos y formas presentes, determinando las interrelaciones del relieve kárstico con el glaciarismo cuaternario y con la morfodinámica periglaciar, estableciendo tres fases de evolución kárstica en función de la sucesión de distintas condiciones morfoclimáticas y de la consiguiente actuación de diversos agentes morfogenéticos (karst preglaciar, glaciar y postglaciar) y definiendo cuatro franjas kársticas a tenor del gradiente altitudinal: área de karst cubierto oceánico de media montaña, sector de los frentes glaciares y las cubetas glaciokársticas bajas, desierto kárstico, y área de karst nival de alta montaña.
Haptoglobin as a biomarker
Authors: Naryzhny S.N. , Legina O.K.
Published: April 2021

Haptoglobin (Hp) is a blood plasma glycoprotein that binds free hemoglobin (Hb) and plays a critical role in tissue protection and the prevention of oxidative damage. In addition, it has a number of regulatory functions. Haptoglobin is an acute phase protein, its concentration in plasma changes in pathology, and the test for its concentration is part of normal clinical practice. Haptoglobin is a conservative protein synthesized mainly in the liver and lungs and is the subject of research as a potential biomarker of many diseases, including various forms of malignant neoplasms. Haptoglobin has several unique biophysical characteristics. Only in humans, the Hp gene is polymorphic, has three structural alleles that control the synthesis of three major phenotypes of Hp, homozygous Hp1-1 and Hp2-2, and heterozygous Hp2-1, determined by a combination of allelic variants that are inherited. Numerous studies indicate that the phenotype of haptoglobin can be used to judge the individual's predisposition to various diseases. In addition, Hp undergoes various post-translational modifications (PTMs). These are structural transformations (removal of the signal peptide, cutting of the Pre-Hp precursor molecule into two subunits, α and β, limited proteolysis of α-chains, formation of disulfide bonds, multimerization), as well as chemical modifications of α-chains and glycosylation of the β-chain. Glycosylation of the β-chain of haptoglobin at four Asn sites is the most important variable PTM that regulates the structure and function of the glycoprotein. The study of modified oligosaccharides of the Hp β-chain has become the main direction in the study of pathological processes, including malignant neoplasms. Many studies are focused on the identification of PTM and changes in the level of the α2-chain of this protein in pathology. These characteristics of Hp indicate the possibility of the existence of this protein as different proteoforms, probably with different functions. This review is devoted to the description of the structural and functional diversity of Hp and its potential use as a biomarker of various pathologies.
Identification of the side population associated with ATP-binding cassette transporters activity using imaging flow cytometry

DyeCycle Violet efflux, caused by ATP-binding cassette transporters activity, was analyzed in human colorectal adenocarcinoma cell lines SW480, HT-29, Caco-2 by neans of FACSAria III flow cytometer and ImageStreamX Mk II imaging flow cytometer. Along with similarity of cytometry data obtained on the two instruments, the use of imaging flow cytometry made it possible to characterize the morphology of side population cells, as well as morphology of other cell populations differing in the degree of dye accumulation. The population of cells, which are smaller than the side population cells and practically do not take the dye, is of the special interest. Probably, this population may contribute to the tumor resistance to chemotherapy.
