Published: December 2020

Phytophthora capsici, es el agente causal de la ‘marchitez del chile’ una de las enfermedades más importantes de este cultivo. Para establecer estrategias de control eficientes es necesario el conocimiento de la diversidad del patógeno, para esto, se realizó esta investigación cuyo objetivo fue determinar el grado de variabilidad de 29 aislados monozoospóricos obtenidos de chile (Capsicum annuum L.) de seis municipios del estado de Guanajuato y dos cepas de referencia de A1 y A2. Todos fueron caracterizados por la forma de crecimiento, tipo de compatibilidad, crecimiento a 35 °C, sensibilidad a mefenoxam y grado de virulencia. Los resultados obtenidos indican que los aislados, presentaron cinco formas de crecimiento: estrellada (62.5%), turuloso (15.62%), estolonífera (12.5%), filamentoso (6.25%) y petaloide (3.12%); su crecimiento a 35 °C fue menor a 30.7% respecto al control crecido a 27 °C, su tipo de compatibilidad fue 65.5% del tipo A1, se encontró sensibilidad intermedia al mefenoxam en 65.5% de los aislados, siendo el resto sensibles. El aislado más virulento fue el D3 y los avirulentos fueron D8, D11 y D12 todos originarios de Dolores Hidalgo. No se observa una relación directa entre la forma de crecimiento, el crecimiento a 35 °C, el tipo de compatibilidad, la resistencia a mefenoxam y el grado de virulencia.

Pneumonia caused by the Novel coronavirus disease 2019 (COVID-19) is a highly infectious disease and the ongoing outbreak has been declared as a Pandemic by the World health organization. Pneumonia is a serious disease in pregnancy and requires prompt attention. Viral pneumonia has higher morbidity and mortality compared to bacterial pneumonia in pregnancy. All efforts are well exerted to understand the newly emerged disease features but still some areas are gray. The treatment is primarily supportive with antivirals, steroids, anticoagulation and antibiotics for secondary bacterial infection. Severe cases require intensive care monitoring with oxygen support, mechanical ventilation. Investigational therapies include convalescent plasma, cytokine release inhibitors and other immunomodulatory agents like interferons. The mortality appears driven by the presence of severe Adult Respiratory Syndrome (ARDS) and organs failure. COVID pandemic is a challenging and stressful socio-economic situation with widespread fear of infection, disease and death. In the specialty of obstetrics and gynecology, studies are being conducted to ascertain the manifestation of disease in pregnant women and the fetal outcome. The aim of our case series is to describe the demographics, clinical characteristics, laboratory and radiological findings, feto- maternal outcome of severe and critical COVID pneumonia in pregnant women in Latifa Hospital.

Authors: Gehan Farid , Reem Kamal , Mohammed Thani Al-Shammari , Mohamed Swaraldahab , Hassan Swaraldahab
Published: December 2020

Trans-radial uterine artery embolization (UAE) is acknowledged as a non- invasive, cost-effective and safe procedure for the treatment of symptomatic fibroids. However, it is associated with the recurrence of symptoms like abnormal uterine bleeding and pressure symptom in some patients. This is a comparative study of our data with other international data, in the context of percentage reduction in fibroid size, accompanying controlling factors, short and long term follow up data analysis of the first two years was done. Careful pre-procedural counseling of future possibility of fibroid recurrence and means of management should be stressed. Materials and methods: A retrospective cohort study at the Security Forces Hospital in Riyadh, Saudi Arabia, was conducted. The study was done from 1st November 2017-31st October 2019, on symptomatic patients diagnosed with fibroids, who refused surgical treatment. The outcomes included: fibroid site, size and anatomical position, patients’ symptoms, general condition, and early and delayed complications. These data were compared with those from other international studies. Results: The study involved 23 patients (mean age: 39 years). The average percentage reduction in fibroid volume was 49%. There were no major complications and no recurrence of symptoms during the covered period. Data analysis revealed a poor correlation between the overall percentage reduction of fibroid size with fibroid number, age of patients’, and body mass indices. Conclusion: Despite poor correlation, we provided preliminary data of the first two years out of the total five-year projected period of the study where it showed effectiveness and relative safety of radial - UAE for fibroid.
Estudo da produção de arroz brasileira e o papel do estado Mato Grosso do Sul
Authors: Sato Leandro Kenji , Reis Joao Gilberto Mendes dos
Published: December 2020

O arroz é considerado alimento básico para mais da metade da população mundial, sendo produzidas cerca de 480 milhões de toneladas por ano. O Brasil é um grande consumidor e produtor de arroz concentrado principalmente na região sul do país. Entretanto, nota-se uma dependência de outros estados inclusive de importação de grãos. O estado do Mato Grosso do Sul (MS), por exemplo, aumentou a sua produtividade em 965% nos últimos 40 anos, porém estranhamente houve grande redução da produção do grão no estado. Diante deste contexto, o presente trabalho tem como objetivo analisar a evolução do cultivo do arroz no país, as principais regiões produtoras e, mais especificamente, mostrar o panorama do cultivo do arroz no estado do Mato Grosso do Sul para identificar possíveis causas que levam este a não figurar como grande produtor apesar da produtividade registrada. Para esse fim foi realizado um estudo bibliográfico e estatístico descritivo. Os resultados mostraram que entre as causas para esse papel pouco relevante de MS está atrelado a baixa qualidade dos grãos produzidos, economias de escala na produção no Rio Grande do Sul, alta produção de soja e milho, baixa disponibilidade de financiamento, preço competitivo do arroz produzido no Paraguai e problemas logísticos.
A marginalização da escrita feminina: a trajetória de obstáculos enfrentados pelas escritoras
Authors: Zukoski Ana Maria Soares
Published: December 2020

O presente trabalho tem por objetivo apresentar um mapeamento das dificuldades que as escritoras encontram para se inserir na seara literária, isto é, no campo literário e no cânone. Tais dificuldades se refratam nas premiações literárias tendo por consequência uma lacuna na representação de obras escritas por mulheres, quase nunca pleiteadas. A partir disso, realizamos um levantamento sobre os Prêmios: Jabuti, Machado de Assis e Camões, a fim de verificar em que medida obras escritas por homens e mulheres são agraciadas pelos prêmios e como a disparidade entre essas representações sinalizam para a marginalização da escrita de autoria feminina.  O trabalho está alicerçado nos pressupostos teóricos da Crítica Feminista e da Literatura de autoria feminina, com autores/as como Woolf (2014), Muzart (2011), Bourdieu (1996), Zolin (2015), Xavier (1999), Schmidt (1999), entre outros/as.
Perlindungan Hak Pengguna Layanan Pinjaman Online dalam Perspektif Hak Asasi Manusia
Authors: Pardosi Rodes Ober Adi Guna , Primawardani Yuliana
Published: December 2020

Tulisan ini bertujuan untuk mengetahui pengaturan pinjaman online saat ini serta mengetahui perlindungan terhadap hak pengguna layanan pinjaman online dalam perspektif HAM. Metode penelitian yang digunakan adalah penelitian normatif. Hasil pembahasan menunjukkan bahwa pengaturan dan pengawasan terhadap pinjaman online telah dilakukan melalui Otoritas Jasa Keuangan. Akan tetapi belum terdapat regulasi tentang financial teknology yang memberikan sanksi terhadap penyelenggara pinjaman online ilegal. Pelanggaran HAM terjadi karena kompleksitas antara kurangnya pengetahuan masyarakat mengenai mekanisme pinjaman online serta belum terdapat regulasi khusus yang mengatur Financial Technology termasuk juga perlindungan terhadap penyalahgunaan data pribadi yang merupakan suatu mekanisme administratif dalam melakukan transaksi Financial Technology. Oleh karena itu dapat disimpulkan bahwa Perlindungan terhadap hak para pengguna layanan pinjaman online masih belum optimal. Kondisi tersebut perlu mendapat perhatian mengingat pengguna layanan memiliki hak dasar yang perlu mendapatkan perlindungan, baik sebagai konsumen maupun sebagai manusia yang sudah memiliki hak dasar sejak dilahirkan. Dengan demikian perlu adanya sosialisasi mengenai pinjaman online, penyusunan Undang-Undang Financial Technology sebagai dasar hukum dalam melakukan penindakan terhadap pinjaman online illegal dan penetapan Undang-Undang tentang Perlindungan Data Pribadi.
Indeterminação do sujeito no português brasileiro:o pessoal tá inventando moda
Authors: Quarezemin Sandra , Fuchsberger Gabriel
Published: December 2020

This paper describes and analyses a new strategy of subject indetermination in Brazilian Portuguese (BP). The new strategy presents generic noun phrases, such astu/você(‘you’),a gente(‘we’),o cara(‘the guy’),a pessoa(‘the person’), etc., in the subject position without an explicit referent. We argue that the type of sentence addressed in this study is devoid of referentiality. Its emergence seems to have to do with the fall of the clitic se, on the one hand, and with the need to fill the pre-verbal position, on the other.
Ruskin’s Ontology of Architecture
Authors: Marques de Abreu Pedro
Published: December 2020

Ruskin’s critique to architecture is usually understood from the subject of style, as the defence of Gothic against Classicism. If that had been the case, his writings about architecture would have lost all of their pertinacity. But that is not the case. This paper inspects the topicality of Ruskin’s thinking about architecture. His observations on the subject are phenomenological observations avant la lettre: the result of his own experience, highly sensitive, and of his personal reflection upon it, deeply human. Almost a century before Heidegger, Ruskin describes the anthropological responsibility of architecture in a very similar manner to the one the German philosopher. My understanding is that Ruskin is revealing the ‘dwelling’ ability that pertains to architecture, and that gives it its proper identity. Without architecture’s stamp on the landscape, it would not be possible for men to ‘dwell’ on Earth, and hence, it would not be possible for men to be rightly humans, i.e. to re-member (in Ruskin’s terminology) – to accomplish that specific human trait of existence that is necessary for an authentic living, which is to be self-aware.
Division, Juncture, System: Bridges and Bridge-Building in the Work of John Ruskin
Authors: Tucker Paul
Published: December 2020

This chapter starts by considering a recent design for a bridge named after Ruskin, whose inadequacy it attributes to disregard for Ruskin's definition of a bridge's basic function as that of safe passage over a river and misapplication of his concept of ‘abstract lines’ as ornament. For Ruskin, curvature determined by that function allowed bridges materially to trace such lines and so epitomize general laws governing landscape composition, natural morphology and human co-existence. Taking it as a figure of connection, threaded as a clue through his work, the chapter explores Ruskin's sense of the significance and sacredness of bridges, manifested especially in the role he assigned to an ideal Pontifex, guarantor of secure passage across national, cultural and cognitive divides.
Ruskin, Dante e l’Europa romantica
Authors: Sandrini Giuseppe
Published: December 2020

My paper aims to show how Ruskin, through Dante’s work, looks for an alternative to romantic aesthetics. In Ruskin’s view, Dante is Medieval Italy (his knowledge of the poet being parallel to his discovery of Italian cities such as Lucca and Verona). Gothic art is the source of Europe: so Dante is «the central man of the world» (The Stones of Venice) and the fulcrum of an aesthetic based on sharpness and allegory, the two attributes that are typical of the architecture of a gothic cathedral. Ruskin’s ideas are then compared to those of Wordsworth and Coleridge, but also to the view of nature of other protagonists of the romantic age in Europe, such as Chateaubriand and Leopardi.
The Stones of Venice: Lady Augusta Gregory and John Ruskin
Authors: Remport Eglantina
Published: December 2020

Lady Augusta Gregory was among those Victorian Anglo-Irish genteel women who were deeply influenced by Ruskin’s views on the political and artistic history of Venice. She stayed at Ca’ Cappello during he visits to Venice, Sir Austen Henry Layard and Lady Enid Layard’s beautiful palace on the Grand Canal. She often walked the streets of the Mediterranean city in search of architectural details that Ruskin mentioned in The Stones of Venice. The chapter considers the significance of these Ruskin-inspired sojourns on the formation of Lady Gregory’s aesthetic sensibilities at the turn of the twentieth century and reveals the true subject matter of one of her Venetian sketches, now held at the National Library of Ireland.
Edited by Ruskin: Francesca Alexander’s Roadside Songs of Tuscany
Authors: Sdegno Emma
Published: December 2020

In 1907 Cook and Wedderburn published the volume XXXII of the Library Edition, grouping together a series of texts “Edited and Arranged by John Ruskin”: Studies of Peasant Life: The Story of Ida, Roadside Songs of Tuscany, Christ’s Folk in the Apennine, Ulric the Farm Servant. Since most of the works were authored by Francesca Alexander the volume is in effect a tribute to this American artist. In this paper I outline the history of the editing of Francesca Alexander’s Roadside Songs of Tuscany, from the manuscript “Francesca’s Book” to the published edition issued in parts between 1884 and 1885. I argue that Ruskin’s interest in the project bears a special relationship to the publication of the Fioretti di San Francesco in mid-nineteenth-century French and English versions, and to the ideological context that generated those publications. Ruskin’s declared aim of conveying to the English mind “some sympathetic conception of the reality of the sweet soul of Catholic Italy” was generated within this context, and his idea of publishing Francesca’s manuscript in a heavily edited and thoroughly new form justifies comparison with continental research into Medieval literature in the last decades of the Nineteenth century.
Ruskin in Translation: Versions of Unto this Last in a Few Europeans Languages
Toward a Reception History of John Ruskin’s Social Thought
Authors: Tizot Jean-Yves
Published: December 2020

The article proposes to review the reception and transmission of John Ruskin’s social thought as expressed in Unto this Last (1862), translated and edited in different European languages. The text itself offers little room for variation, so that interpretations are voiced mainly in the editors’ introductions or afterwords, when they exist. This study finds that very few foreign versions do justice to Ruskin’s radicalism in his anti-capitalist and anti-industrial critique of modern society, his rejection of ‘progress’ and his refutation of political economy, while most take advantage of the occasion to express their own political and social views, often in blatant betrayal of Ruskin’s ideas.
The Apostle of Beauty: Some Turn-of-the-Century Perceptions of Ruskin in Central and Eastern Europe
Authors: Eagles Stuart
Published: December 2020

Ruskin’s writings were widely available in a range of European languages by the early years of the Twentieth century. We focus here on the Czech lands (mainly Bohemia), Hungary and Poland, with some comparative references to Russia. In these nations, Ruskin was found in partial and complete translations of individual works, anthologies of selected passages, critical studies, journal articles and in the debates these publications helped to stimulate. Ruskin was also read both in the original English, and widely in French translation. But it was not until Ruskin’s ideas began to circulate in these countries’ native languages that Ruskin’s literary merit and philosophical insights could be seriously engaged with.
Peçeli baykuşlarda (Tyto alba) Glandula Uropygialis’in Morfolojik ve Histolojik Analizi
Authors: YILMAZ Bestami , YILMAZ Rahsan
Published: December 2020

Glandula uropygialis (uropygial bez), kuşlarda derinin holokrin yapıda bir yağ bezidir. Bu çalışma erkek peçeli baykuşlarda (Tyto alba) uropygial bezin morfolojik ve histolojik yapısını belirlemek amacıyla yapıldı. Çalışmada erişkin yaşta 4 adet erkek peçeli baykuş materyali kullanıldı. Kuşların kuyruk bölgesinde yer alan bezler diseke edilerek vücuttan ayrıldı. Bezlerin morfometrik incelemeleri yapıldı. Bezin histolojik yapısını ortaya koyabilmek amacıyla doku kesitleri Hematoksilen & Eozin (H&E) ve Masson Trichrome yöntemleri ile boyandı. Boyanan kesitler ışık mikroskobu ile incelendi. Topografik incelemede, bezin synsakrumun kaudalinde, kuyruk omurlarının üzerinde yerleştiği belirlendi. Bezin ortalama ağırlığı 0.493±0.02 g, relatif indeks değeri (bez ağırlığının vücut ağırlığına oranı) ise 0.10±0.01 olarak bulundu. Histomorfolojik incelemede her bir lobun dışarıdan bağ doku ile sarıldığı görüldü. Loblar sıralı olarak dizilmiş tubulo-alveolar bezlerden oluşmaktaydı. Bezler ince bağ doku ile sınırlandırılarak birbirinden ayrılmışlardı. Bezler arasındaki bağ doku içerisinde kan damarları yer almaktaydı. Bezler kranialden kaudal uca doğru gidildikçe şekil ve hücre dizilişi bakımından farklılık gösteren 3 farklı bölgeden oluşmaktaydı. Sonuç olarak peçeli baykuş uropygial bezinin gerek morfolojik gerek histolojik yapısı bir takım yapısal farklılıklara rağmen literatürlerde bildirilen diğer birçok kanatlı hayvanlardaki ile benzerdi.
The association between physical fitness and mathematics scores in elementary schools in Indonesia
Authors: Dinangsit Dinar , Muhtar Tatang , Akin Yogi
Published: December 2020

A continual pressure within the educational system in Indonesia to focus on high levels
of academic achievement is a major barrier to implementing an effective physical
education curriculum in Indonesia. The conflict between the implementation of a
movement based approach (MBA) and a sport based approach (SBA) presents another
continuing problem. The current approach leads more to an orientation towards the
acquisition of sport skills rather than the attainment of objectives of cognitive
development. This study is aimed to reveal the association between the physical fitness
and academic achievement of children in Sumedang, West Java. Four physical fitness
test items and a specially constructed mathematics test were administered to 265
children from grades four and five. The ability of performance on the physical fitness
tests to predict performance in mathematics was calculated by linear multipleregression
analysis. The findings revealed that there was a significant association,
although low, between the physical fitness components and mathematics achievement.
Sit ups and squat jumps showed low partial correlations and the relationships for push
ups and the 400 metre run were negative Limitations in the ability of the children to
perform the tests were suggested as an explanation for the mixed results. It was argued
that this weakness served to emphasise the importance of giving greater priority to
physical education and the quality of its teaching within the school curriculum.

Cassia singueana L. is widely used in traditional medicine for the treatment of various ailments. The present work was set to investigate the antioxidant and antimicrobial activity of this plant and its secondary metabolites. Three bioactive compounds, lupeol, eugenol and octadecadienoic acid methyl ester, were isolated from the root extract of the plant using bioactivity-guided normal phase column chromatography. The antioxidant effect was studied using the in vitro assays, e.g., 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), superoxide anion and metal chelation methods. The compounds were screened for their antimicrobial activity against four bacteria, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus pneumonia and a fungus, Candida albicans using the agar diffusion method. The MIC/MBC of the extracts were determined by the micro-dilution method. Chemical structures of the isolated compounds were determined using FTIR and NMR spectroscopy. Whilst all three compounds showed certain levels of antioxidant activity, the most prominent antimicrobial activity was observed only against S. aureus. In general, results from the work provided some evidence to support the traditional medicinal uses of C. singueana. Keywords: Detection, elucidation, phytochemical, Cassia singueana.

This open-label non-controlled study is to evaluate the effects of black vinegar intake for 8 weeks on the anthropometric measures, cardiometabolic profiles, and insulin sensitivity among impaired fasting glucose adults. 32 subjects (14 males and 18 females) were recruited with the mean age of 56.3 (from 25 to 65). Black vinegar 50 ml was diluted to 500 ml with drinking water and was given to all subjects for 8 weeks. At baseline and 8-week, all study subjects received 75 g of oral glucose tolerance test (OGTT) after 10 h of fasting. Venous blood was collected at 0, 30, 60, 90 and 120 min. Plasma glucose and insulin levels were measured using the glucose oxidase method and radioimmunoassay method. Anthropometric variables, blood pressure and blood lipid profiles were measured using standard methods. The Wilcoxon signed-rank test was used to compare the difference between baseline and after eight weeks. After eight weeks, the body weight and BMI decreased from 68.2 ± 14.4 kg to 67.6 ± 14.2 kg and 26.3 ± 4.5 kg/m2 to 26.0 ± 4.4 kg/m2, respectively, with statistical significance (p < 0.05). Triglyceride level decreased from 152.5 ± 134.7 to 140.6 ± 93.8 mg/dl but without statistical significance. The blood glucose levels at 120 min of OGTT decreased from 178.8 ± 57.0 to 173.7 ± 57.5 mg/dl and the insulin levels at 120 min of OGTT increased from 117.5 ± 74.2 to 126.4 ± 95.9 IU/L but not statistically significant (p > 0.05). There is a slight decrease of body weight and BMI, but no significantly change in blood pressure, lipid profiles, and insulin sensitivity after eight weeks of black vinegar intake among impaired fasting glucose adults. However, further large-scale and longer studies are needed to explore the effects of black vinegar on cardiometabolic profiles and insulin sensitivity. Keywords: Black vinegar, anthropometric measures, lipid profiles, insulin sensitivity, impaired fasting glucose.

Published: December 2020

O presente trabalho tem como proposta relatar uma experiência acerca da operação básica de multiplicação, utilizando como pressupostos o estudo dos métodos multiplicativos alternativos desenvolvidos na civilização chinesa e a tendência metodológica História da Matemática. Esse estudo se justifica pela possibilidade de apresentar novas estratégias de ensino da Matemática. A base metodológica está apoiada em pressupostos da pesquisa qualitativa e de cunho bibliográfico. A revisão teórica foi realizada a partir de um levantamento de literatura no portal da CAPES de Teses e Dissertações e no google acadêmico, considerando a expressividade e qualidade dos trabalhos publicados nos referidos portais. A busca compreendeu os achados mais recentes publicados no período de 2014 a 2018. Para concretização da proposta, recorreu- se a um estudo de caso, tendo como objeto de estudo uma amostragem de alunos do 1º e 2º anos da Educação Básica de Ensino Médio de uma escola estadual, situada no município de Cedro- CE. Com base nos resultados, foi possível perceber que houve um avanço em relação ao número de alunos que acertaram as questões utilizando o método chinês. Ao que tudo indica, a possibilidade de sair da rotina normal da sala de aula, favoreceu o desempenho dos alunos, influenciando diretamente no seu processo de aprendizagem. Essa proposta aponta como uma alternativa para preencher possíveis lacunas na apreensão de conceitos matemáticos pelos alunos. Além disso, a tendência metodológica História da Matemática, indica a renovação da prática pedagógica docente diante do novo contexto escolar, de modo a articular o ensino de Matemática na atualidade com a prática desenvolvida nas civilizações antigas.
Teratoma extragonadal del omento mayor, una localización poco usual: reporte de caso y revisión de la literatura
Authors: Arenas Juan C. , Romo Julián A. , López-Bello Laura
Published: December 2020

Introducción. Los teratomas son masas de células totipotenciales, frecuentes en los ovarios o testículos. Su localización extragonadal es rara, siendo el epiplón aún más infrecuente. Hasta la actualidad se conocen aproximadamente 34 casos similares en la literatura. Presentación del caso. Se presenta una paciente de 61 años, con dolor en hemiabdomen inferior asociado a sensación de masa, con marcadores tumorales negativos e imágenes diagnósticas que muestran una masa encapsulada y calcificación anular interna sugestiva de necrosis grasa antigua versus tumor desmoide. Por la presentación clínica y los hallazgos imagenológicos se decide llevar a laparotomía exploratoria donde se encuentra masa quística dependiente de epiplón, con material sebáceo en su interior entremezclado con pelo y fragmentos óseos, que se reseca en bloque sin complicaciones. El informe del estudio histopatológico finalmente concluyó la presencia de un teratoma quístico maduro con cambios degenerativos. Por evolución satisfactoria se da egreso hospitalario. Discusión. El teratoma quístico extragonadal del epiplón es exótico en la literatura mundial, con escasos reportes de casos. En este caso, la resección mediante laparotomía resultó exitosa y sin complicaciones. Por su baja incidencia, la laparotomía ha sido una opción válida y segura para el manejo, no obstante conocer el caso permite plantear un abordaje con técnicas mínimamente invasivas.

Authors: Barrera Lozano Luis Manuel , Gutierrez Montoya Jorge Ivan , Henao Sierra Jorge Enrique
Published: December 2020

Introducción. Cerca del 15 % de los pacientes con insuficiencia renal crónica terminal tienen alteraciones de las vías urinarias inferiores. Estas anomalías eran consideradas una contraindicación para el trasplante renal. Por lo anterior, el objetivo del presente trabajo es describir el comportamiento sociodemográfico y clínico de los pacientes trasplantados renales con ureterostomía cutánea como técnica de derivación definitiva de las vías urinarias. Métodos. Se realizó un estudio descriptivo, longitudinal y retrospectivo de los pacientes trasplantados renales con vejiga anormal y ureterostomía cutánea, entre enero de 1973 y octubre de 2012. Resultados. En 4.294 trasplantes renales, se practicaron 24 (0,55 %) ureterostomías, 19 (79,1 %) como técnica inicial y 5 por falla de la ureteroneocistostomía. Diez (41,7 %) ureterostomías fallaron, la mayoría (8 casos) por estenosis. Se presentó infección urinaria en 20 pacientes y la mortalidad fue del 8,3 % (2/24). El 50 % (12/24) de los pacientes con trasplante de riñón estuvieron libres de infección urinaria durante el primer año. La supervivencia del riñón trasplantado fue de 93,8 % (23/24) a los 18 meses, de 85,9 % (20/24) a los 36 meses y de 66,7 % (16/24) a los 50 meses de seguimiento. La supervivencia de los injertos con ureterostomía sin infección fue del 100 % durante el periodo de seguimiento, mientras que la supervivencia de los riñones con infección urinaria fue de 93 % (23/24) a los 18 meses, de 76 % (18/24) a los 36 meses y de 54 % (13/24) a los 50 meses (p=0,235). Conclusiones. La ureterostomía cutánea es una alternativa segura para la derivación urinaria en pacientes trasplantados renales con alteraciones de la vejiga que no permite su uso o preparación antes del trasplante.

Published: December 2020

Introducción. Alrededor de un 10 % de las laparoscopias se convierten a cirugía abierta por dificultades en obtener una visión crítica durante la colecistectomía en colecistitis severas. La colecistectomía subtotal es una posibilidad terapéutica disponible, que disminuye la tasa de conversión en cirugía laparoscópica y mantiene bajas tasas de morbilidad y mortalidad. Métodos. Estudio descriptivo, retrospectivo, de pacientes sometidos a colecistectomía subtotal en la Clínica CES (Medellín, Colombia) entre enero y diciembre de 2015. Se identificaron variables demográficas, detalles de la cirugía, morbilidad y mortalidad. Resultados. De un total de 710 colecistectomías en dicho periodo, a 17 (2,4 %) se les realizó colecistectomía subtotal. Quince (88 %) de ellas fueron por laparoscopia y dos requirieron conversión. La distribución en cuanto a sexo fue similar (10 mujeres / 7 hombres) y la edad promedio fue de 51 años. El tiempo quirúrgico promedio fue de 119 minutos. En 14 (82 %) pacientes se dejó drenaje subhepático. Dos pacientes presentaron fístula biliar y un paciente reingresó por un hematoma; no se presentaron otras complicaciones. La estancia hospitalaria promedio fue de 5,2 días.  Discusión. La colecistectomía subtotal es una alternativa en pacientes con colecistectomía difícil y en nuestra experiencia presenta una alta tasa de éxito.

The article analyzes the current processes on the global labor market in Russia and the Republic of Bashkortostan. Changing demographic proportions, the pension reform, migration processes, intensive development of production technologies, automation, the use of artificial intelligence all these factors are undoubtedly transforming the labor market environment. The content of occupation is changing, structural changes in the economy lead to the dropping-out of a number of specialties and the emergence of new ones, which did not exist before. To match the supply of labor resources to the modern requirements of the economy, new competencies of workers as well as continuous training or retraining are required. Educational institutions have to adapt to the new requirements of the labor market environment to meet the needs of the labor market for qualified specialists with relevant knowledge and skills. Major changes in the labor market amid the spread of the new coronavirus infection have affected most countries of the world economy, including Russia. A long period of restrictions in most industries is reflected in the economic indicators of enterprises, development opportunities, and the number of required workers. The situation with the pandemic clearly demonstrates how unstable the modern labor market is; how events that occur in one country in the world are capable of undermining the whole balance, even in fairly stable and durable economic systems. The article analyzes the situation on the labor market of the Republic of Bashkortostan. The main problems of the region in this direction are highlighted. The analysis of the situation in the registered labor market showed that in 8 months of 2020 the number of officially registered unemployed increased 5 times, the level of registered unemployment increased 5.5 times, tension in the labor market increased 3 times. In the context of a worsening economic situation caused by an unfavorable epidemiological situation, the situation with the employment of citizens has become more complicated. The analysis showed that for several years the employment rate remained stable at 70%, and by September 2020 it was 17.4%. Currently, the labor market in Russia experiences the consequences of the economic crisis caused by the unfavorable epidemiological situation. The crisis is changing the forms of employment, which is becoming remote, non-standard, online professions appear. The structure of labor demand is changing. Labor resources will be rebuilt or replenish the modern labor market. In these conditions, the role of the state is growing significantly and there is no doubt in the need of the development of the anti-crisis plan for the labor market’s regulation.

Internal tourism has tremendous potential for becoming one of the leading non-resource sectors in the Russian economy enabling its further development. The implementation of this potential will be largely supported by its promotion using Internet marketing technologies, as this is one of the major factors to maintain the demand for internal tourism not only during the period of closed borders, but also over the long term. The paper substantiates objective feasibility for the transition from 'analogue' to digital marketing, as evidenced by global trends in the digital development pointing out to the fact that digital technologies, mobile devices and social networks have become an indispensable part of people’s everyday life throughout the entire world. The conclusion is made about the necessity of performing prompt recordings of the trends formed in the sphere of Internet marketing in order to provide effective promotion of regional tourism.

STUDYING THE EFFECT OF THE SCHEME OF EXPOSURE TO MICROWAVE ELECTROMAGNETIC FIELDS ON THE HARDNESS OF THE CURED CARBON FIBER-REINFORCED PLASTIC WITH LIGHTNING-PROTECTION GRID APPLIED ON ITS SURFACE

Currently, the use of fiber-reinforced polymer composite materials (PCM), in particular, carbon plastic and fiberglass, is much promising in manufacturing structural elements of aircrafts and wind turbines. In order to increase the resistance of these materials to static electricity and lightning strikes when passing storm fronts, the structure of the PCM includes various lightning protection coatings (LPC). The most common LPC are in the form of copper grids. The fin assembly and planes of aircrafts and also large-sized blades of wind turbines are exposed to cyclic high-amplitude and low-frequency bending loads as well as vibrations. Collisions with solid objects are quite possible. Thus, hardness is one of the key characteristics of PCM that determines their performance properties. Strength and endurance of PCM components can be increased by short-term exposure to a microwave electromagnetic field. The presence of a built-in metallic structure brings additional uncertainty in the tolerance to operating loads by anisotropic PCM, as well as in the process of their interaction with an ultrahigh frequency electromagnetic field. Research was performed on the hardness of carbon fiber-reinforced plastics with built-in LPC using various exposure schemes to a microwave electromagnetic field: from the side of the LPC, from the side opposite to the LPC and sequential processing from both sides. It was found that short-term processing in a microwave electromagnetic field with energy flux density of (17-18)×104mW/cm2 did not lead to any change in the initial hardness of the surface of the samples. However, the uniformity of hardness distribution on the surface of the samples in- creased by 35.8-70%, thus ensuring a more adequate tolerance to loads of different nature. The obtained results can be used in the development of finishing technologies to post-process PCM components and improve the latter’s stability to dynamic loading.
MAGNETIC FLOW AND ITS QUANTIZATION
Authors:   Vladimir Electromechanical Plant, PAVLOV V.D.
Published: December 2020

It is noted that the elementary electric charge is equal to e , from which fact the well-known principle of quantization of the electric charge definitely follows, namely, the electric charge is quantized and a quantum is the charge of the electron e (or positron). Or any change in the charge is equal to an integer number of electrons (or positrons). The formally identical transformation of the principle of quantization of the electric charge allows formulating the principle of quantization of the magnetic flux, namely, the quantity inverse to the magnetic flux is quantized and a quantum is the inverse of the quantum of the F. London magnetic flux. Or any change in the reciprocal of the magnetic flux is equal to an integer number of quantities inverse to the quantum of the F. London magnetic flux. The reciprocal of the magnetic flux quantum is equal to the sum of two quantities inverse to the quantum of the F. London magnetic flux. The validity of the principle of quantization of the magnetic flux with respect to the hydrogen atom is illustrated by Theorem 1: quantization of the energy of the hydrogen atom is a consequence of the principle of quantization of the magnetic flux. Theorem 2 is proved: the magnetic flux of a hydrogen atom in the ground state is equal to the quantum of the F. London magnetic flux. Theorem 3 is proved: the quantum of the magnetic flux is not the minimum possible for a nonzero magnetic flux. It is established that the quantum of the magnetic flux is not a quantum in the sense of a portion (like the F. London quantum). A quantum is the inverse of the quantum of the F. London magnetic flux. It is established that the magnitude of the magnetic flux quantum is not the minimum possible for a nonzero magnetic flux. It is established that the magnetic flux of a hydrogen atom in the ground state is equal to the quantum of the F. London magnetic flux. A discrete set of energies of the hydrogen atom is noted to be a consequence of the solution of the Schrödinger equation, which, in turn, is phenomenological. The reverse discourse used in the proof of Theorem 1 can show that the Schrödinger equation is a consequence of the principle of quantization of the magnetic flux.

Nucleosides containing five-membered deoxy-carbohydrates in the glycosidic part, such as zalcitabine, 2'.3'-dideoxyuridine, stavudine, are widely used in acquired immunodeficiency syndrome (AIDS). A number of 2'.3'-dideoxynucleosides is an effective inhibitor of type-1 immunodeficiency virus (HIV-1) in humans. Levoglucosenone and cyrene (dihydrolevoglucosenone) are unique compounds, optically pure ketones of carbohydrate nature obtained from renewable bio-raw materials and available by pyrolysis of any cellulose-containing materials. They are promising carbohydrates for the production of modified nucleosides; in addition, they are commercially available. Based on levoglucosenone, we synthesized chiral carbohydrate blocks for dideoxy-nucleosides, namely, tertbutyldimethylsilyl derivatives of (S)-5-(hydroxymethyl)-2.5-dihydrofuran-2-ol and (S)-5-(hydroxymethyl)tetrahydrofuran-2-ol. At the first stage of the synthesis, a one-stage modification of the pyranose form of levoglucosenone and cyrene to γ-butanolides was carried out by Bayer-Williger oxidation using H2O2 in the presence of Amberlyst-15 in water. The reduction of unprotected hydroxymethyl-γ-butanolide obtained from cyrene to lactol was studied. The reduction of γ-butanolide by the action of BH3·SMe2, Red-Al, or LiAlH(OtBu)3 in THF at 0° C leads mainly to triol, the product of complete reduction. The desired lactol was obtained using iBu2AlH at -78°C in CH2Cl2 in good yield. Raising the reaction temperature to 0° C led to a decrease in the yield of lactol. It has been established that (S)-5-(hydroxymethyl)-tetrahydrofuran-2-ol exists in both five-membered and six-membered forms. Due to the fact that the target lactols easily undergo a transition from the furanose to the pyranose form, they are not used to produce nucleosides. Therefore, we have studied the approach to the synthesis of stable five- membered lactols. For this purpose, in lactones obtained by the Bayer-Williger reaction, the primary hydroxyl group was blocked using TBSCl. Subsequent reduction of the esters using iBu2AlH gave lactols that existed exclusively in the furanose form. The total yield of the target (S)-5-(hydroxymethyl)-2.5-dihydrofuran-2-ol obtained from levoglucosenone was 39% and (S)-5-(hydroxymethyl)-tetrahydrofuran-2-ol obtained from cyrene was 65%.

The article presents the results of elemental analysis of the composition of metal objects obtained from the burial grounds dating back to the Srubna culture of the South Urals. The data were received through analyzing the most common category of jewelry - bronze bracelets. The prevailing shapes are open grooved bracelets with rounded ends, as well as bracelets made of rods and twisted wires with semicircular and triangular sections. The main purpose of this work is to give a general description of the oldest metal composition and compare the series of findings from the Cis-Urals and Trans-Urals. The first stage of the work involved examination of 10 samples of the Trans-Ural group of objects from Tavlykaevo 1 and 2 burials and 7 decorations from the Srubna burials of the Staro-Yabalakly necropolis (Cis-Urals). The principal metallurgical group includes tin bronzes with three-component alloys of copper, tin and lead or copper, tin and antimony. In terms of its composition, the series of findings under study was quite clearly differentiated. In the Trans-Ural assemblages, objects with addition of lead were primarily found in the burials of Tavlykaevo I burial ground, while in Tavlykaevo 2 burial ground, copper-tin alloys with antimony inclusions prevailed. In the Staro-Yabalakly necropolis, a single object might contain an admixture of antimony and lead. Depending on the elemental composition of non-ferrous metals in various categories of objects, it is hypothetically possible to reconstruct the directions of metal supply to the South Urals and characterize the local features of the metallurgy development in this region in the Bronze Age.
