РАЗРАБОТКА ТРЕХМЕРНОГО МОДЕЛЬНОГО СТЕНДА ДЛЯ УСТАНОВЛЕНИЯ РАСПРЕДЕЛЕНИЯ НАПРЯЖЕНИЙ В СФОРМИРОВАННОМ В УЩЕЛЬЕ МНОГОЯРУСНОМ ОТВАЛЕ
Authors: Манукян Л.А. , Казарян А.А.
Published: May 2022

Добыча руд цветных металлов в нагорных карьерах в основном сопровождается
образованием породных отвалов в ущельях и на подотвальных территориях со сложными рельефными условиями. В настоящее время на нагорных карьерах Армении
сформировано и эксплуатируется несколько десятков многоярусных отвалов, на
которых размещены сотни миллионов кубометров горной массы. При проектировании
и разработке рационального способа отвалообразования и определении емкости
многоярусных отвалов, сформированных в ущельях, определенный интерес представляет изучение характера распределения напряжений в теле отвала в процессе его
формирования. В связи с этим возникают определенные трудности, связанные с
объективностью оценки напряженного состояния и точностью расчетов рациональных
параметров, обусловливающих устойчивость отвала.
В настоящее время во многих регионах мира наблюдается устойчивая тенденция постепенного перемещения сырьевой базы в гористую местность. Наряду с другими проблемами, обусловленными деятельностью горнорудного производства в сложных рельефных условиях, следует подчеркнуть значительные трудности, возникаемые при установлении рациональных параметров многоярусных отвалов, сооружаемых в ущельях. В проектных решениях, посвященных сооружению многоярусных
отвалов в сложных рельефных условиях, недостаточно изучены вопросы, связанные с
выявлением характера изменения и перераспределения напряжений в отсыпанной в
ущельях горной массе, что важно для обоснования устойчивости и определения
параметров многоярусного отвала.
В работе предпринята попытка решить эту объемную задачу методом физического моделирования путем создания трехмерного модельного стенда новой конструкции, выявления в модели многоярусного отвала закономерностей изменения и
определения напряжений в центральной осевой плоскости эквивалентного материала
в зависимости от величины двугранного угла, образованного боковыми поверхностями ущелья.

SLOPE STABILITY ASSESSMENT OF THE SOUTHWEST OVERALL SLOPE OF THE QAJARAN OPEN-PIT MINE BASED ON THE GSI ROCK MASS CLASSIFICATION SYSTEM
Authors: Hovakimyan V.V.
Published: May 2022

The application of assessing the fracturing quality of rock masses based on the
classification system for determining the boundary parameters of the Qajaran open-cast mine slope is substantiated. In the certain geomechanical environment, the long-term slope stability of the south-west wall of Qajaran open-pit mine based on the Geological Strength Index (GSI) classification system is estimated. A comparative analysis between the results with other well-known classification systems, such as MRMR, Q-system and RQD, and the outputs of the proposed GSI system is made. A good agreement between the results obtained from Barton’s Q-system and Hoek’s GSI classification systems is found. It is highly desirable to quantify the rock mass based on 2 and/or more classification systems (e.g. Hoek’s GSI and Barton’s Q-system) to provide much more reliable and reasonable estimates. The stability analysis of Qajaran open-pit overall slope at different scales based on the confirmed lower and upper bounds of the GSI classification system and compared with the results of the accepted stability criteria is performed. It has been shown that when there are limited input data of the jointed rock mass in the current geomechanical environment, it is expedient to use Hoek’s GSI classification system to determine the geometric parameters at different scales
at the first development stage of the rock slope designs and estimate the stability of the overall slopes of deep open-pit mines based on Hoek-Brown failure criterion.

Fuzzy Based Tool Wear Monitoring of the CNC Milling Machine
Authors: GÜCÜYENER İsmet
Published: May 2022

In machining systems, cutting tool wear causes errors in precision manufacturing processes. It causes a waste of raw material processed in faulty production and a waste of time spent in vain. Continuous monitoring of tool wear and generating an automatic warning in case the wear value falls outside the tolerance value will resolve these issues. Vibration values and the powers drawn by the motors provide important clues in the non-contact monitoring of cutting tool wear during production. In this study, thanks to the use of low-cost sensors and the applied fuzzy decision mechanism , the cutting tool status could be detected online with an accuracy of 90.17 percent. The RMS value of the power drawn by the spindle motor, average value of fiber optic sensor output voltage, and the average values of selected fiber optic sensor output wavelet transformations are the inputs of the designed system. The output of the system is the cutting tool wear value estimated by the fuzzy decision mechanism.

Published: May 2022

Neutropenia that occurs in hematologic malignancies or solid tumors may increase the risk of infection and lead to morbidity and mortality. This study aims to investigate the microbiological profile and antibiotic susceptibility pattern in children with malignancy and febrile neutropenia (FN). A cross-sectional study was conducted from January 2017 to June 2021 using medical records from the pediatric inpatient hematology-oncology ward of Dr. Soetomo General Hospital. The inclusion criteria are children with malignancy aged ≤ 18 years, experiencing a febrile episode of neutropenia, and were examined for blood culture at the onset of FN. A total of 291 children were eligible patients. Out of 291, 65 of them had a bacterial infection from blood cultures. Out of 65, almost 57% were dominated by Gram-negative bacteria (GNB). Gram-positive bacteria (GPB) that are often recognized are Staphylococcus hominis, Staphylococcus epidermidis, and Staphylococcus aureus. Meanwhile, the GNB are Pseudomonas aeruginosa and Klebsiella pneumoniae ESBL+. The majority of GNB is almost 100% resistant to ampicillin meanwhile, GPB also reported resistance to β-lactamase. We found no correlation between microorganism infection and malignancy. GNB and GPB are partially resistant to commonly used antibiotics, especially β-lactamases and ampicillin. Alternative therapies are needed to resolve this matter.

Authors: Safitri Ratu , Siahaan Marlinda , Ghozali Mohammad
Published: May 2022

Streptococcus pneumoniae is a normal flora in the upper respiratory tract but can cause Acute Respiratory Tract Infection (ARI), peritonitis, sepsis and meningitis. The widespread use of inappropriate antibiotics to treat Streptococcus pneumoniae infection causes antibiotic resistance. Meanwhile, Streptococcus pneumonia requires iron in its growth, namely as a cofactor for the ribonucleotide reductase enzyme, which plays a vital role in DNA synthesis. This study aimed to determine the antimicrobial activity of sappan wood extract (SWE) against Streptococcus pneumonia and the role of SWE as iron chelators on antimicrobial activity. The study was conducted by establishing a minimum inhibitory concentration (MIC) and a minimum bactericidal concentration (MBC) against Streptococcus pneumoniae and is evaluated using Total Plate Count (TPC), the diameter of the inhibitory zone and the measurement of iron levels using Atomic Absorption S. pectrophotometer. The results showed that the MIC values for Streptococcus pneumonia 103 and 105 CFU/mL were 32 ppm and 64 ppm, respectively, with the MIC values of 64 ppm and 128 ppm, respectively.

Published: May 2022

Background: Transcobalamin (TC) is a carrier protein and it delivers vitamin B12 to the cellular TC receptor. TC II deficiency is a very rare disease and is life-threatening if left untreated. It is an Autosomal recessive disease and needs lifelong treatment. The clinical presentations are variable, started at early infancy, and sometimes mimic severe combined immunodeficiency or acute leukemia. It includes failure to thrive, diarrhea, anemia and or pancytopenia, hypotonia, developmental delay, and recurrent infection. Diagnosis of TC II deficiency is suspected based on clinical presentations with megaloblastic anemia, the elevation of plasma homocysteine, and urine methylmalonic acid level with a normal vitamin B12 and folate level. Molecular analysis of the TCN 2 gene is needed for confirmation of the diagnosis. Case Presentation: We present a case of 2 years old Saudi boy who was admitted to the hospital with a history of fever, recurrent chest infection, failure to thrive with diarrhea, and hypotonia, and his complete blood counts showed Pancytopenia. Though, normal vitamin B12 level and folate level, homocysteine, and urine methylmalonic acid lever were elevated. Peripheral smear and bone marrow aspiration and biopsy revealed Hypersegmented neutrophils and megaloblastic change.

Authors: Shamly M. , Nasim Iffat M. D. S
Published: May 2022

The effectiveness of adhesive restorations depends on a durable long-term dentin bond. Due to collagen fibril denaturation, the consistency and durability of bonding to caries-affected dentin can be questioned as compared to sound dentin. Exogenous cross-linking agents have been suggested as a viable method of inhibiting MMP activity and retaining collagen within the dentin-bonded interface. Due to their strong antioxidant capacity, flavonoids are natural cross linkers that play an important role in protecting unprotected collagen fibrils inside the hybrid layer. This study aimed to evaluate the effectiveness of flavonoids incorporated dentin adhesives in improving the bond strength of composite resin. A search was performed in the electronic databases (PUBMED CENTRAL, Medline, Scopus, Lilacs, Science Direct, Google scholar and Hand Search) using search terms alone and in combination by means of PUBMED search builder upto March 2021. Also cross check of  reference was done on all potentially eligible articles. Initially 47 articles were identified.2 articles were removed because of duplicates. After title and abstract screening 27 articles were removed.After reading full texts,4 articles were removed and finally 14 articles were included in this review for detailed analysis.

MTA has long been used as a Pulpotomy agent to preserve the pulp vitality, but there is a need to have an evidence-based approach when selecting the most appropriate pulpotomy agent which will be suitable for both dentitions, as the pulp of primary and permanent teeth have many histological and morphological differences. This systematic review aimed to evaluate the success of pulpotomy with MTA in primary and permanent teeth. A computerized literature search was performed through five databases: PubMed, Google Scholar, Microsoft Academics, EBSCO, and Science.gov to identify articles up to December 2020. Randomized controlled trial studies were selected in accordance with the inclusion and exclusion criteria. Out of the 5070 publications initially identified, only 18 studies that fulfilled the inclusion criteria were included in the review. Out of those 18 studies, 9 were studies performed on primary teeth, and the other 9 were performed on permanent teeth. After thorough review and evaluation, it was found that overall treatment success in primary teeth was 88.89-100% and it was 85-100% in permanent teeth. Overall clinical and radiographic success rates after follow-up showed that MTA pulpotomy showed slightly better results in primary teeth as compared to permanent teeth.

Authors: Román González Alejandro , Padilla Zambrano Huber Said , López Montoya Vanessa , Gutiérrez Johnayro , Builes-Barrera Carlos Alfonso
Published: May 2022

Contexto: La acromegalia es causada en la gran mayoría de los casos por tumores hipofisiarios productores de hormona de crecimiento. Estos tumores suelen ocurrir de manera esporádica y raramente de forma hereditaria. En los últimos años se ha explorado el panorama de las mutaciones y síndromes familiares asociados a la acromegalia y al gigantismo.
Objetivo: Esta revisión se concentra en el conocimiento actual de las bases genéticas causantes de la acromegalia familiar.
Metodología: Se revisaron las bases de datos electrónicas y textos guías de endocrinología y se resumen las enfermedades genéticas asociadas a acromegalia.
Resultados: Las causas genéticas de acromegalia son el complejo de Carney, la neoplasia endocrina múltiple tipo 1, los adenomas pituitarios aislados familiares (FIPA), el acrogigantismo ligado al X (XLAG), la asociación de feocromocitoma/paraganglioma/adenoma pituitario familiar (3P), el síndrome de McCune-Albright (SMA) y la neurofibromatosis tipo 1.
Conclusiones: Se debe buscar activamente neoplasia endocrina múltiple en los pacientes con acromegalia mediante la medición de calcio y hormona paratiroidea. Además, siempre debe preguntarse por antecedentes familiares buscando FIPA y en casos muy jóvenes o con manifestaciones asociadas sospechar una causa genética.
Comemorar a posse de Thomaz de Araújo: a construção de um lugar para o Seridó na memória histórica do RN: a construção de um lugar para o Seridó na memória histórica do Rio Grande do Norte
Authors: Costa Bruno
Published: May 2022

O Instituto Histórico e Geográfico do Rio Grande do Norte foi criado no início do século XX, com o objetivo precípuo de construir um lugar para o estado na memória nacional. Uma das estratégias utilizadas pelos sócios da referida agremiação para a consecução desse projeto foi o de organizar e promover diversos atos comemorativos. Uma das datas celebradas foi o primeiro centenário da posse constitucional do capitão Thomaz de Araújo Pereira, no cargo de primeiro presidente da província. Nesse sentido, o presente artigo tem como objetivo analisar as condições de emergência desse ato comemorativo levado a cabo pela agremiação, evidenciando a topografia de interesses envolvidos nessa engenharia memorialística. Parte-se da hipótese de que os elementos políticos presentes no interior do instituto, e, também, fora dele, foram fundamentais para a conformação desse arranjo comemorativo.
Não ao peso, não ao recrutamento: os Quebra-quilos e as autoridades públicas no Rio Grande do Norte (1874-1875)
Authors: Brito João
Published: May 2022

No ano de 1874 as notícias sobre as ações dos Quebra-quilos circulavam com grande velocidade na província do Rio Grande do Norte. As feiras, casas comerciais e tabernas eram espaços privilegiados para a disseminação das fofocas e mexericos em torno de uma onda de revoltas nascidas no interior da Paraíba do Norte. A cada momento, notícias chegavam aos ouvidos de autoridades públicas, mas também de pessoas que se mostraram insatisfeitas com a política imperial, com os impostos municipais, com o recrutamento por sorteio e, sobretudo, com a lei que estabeleceu oficialmente o Sistema Métrico Decimal Francês (SMD), substituindo as tradicionais costumeiras medidas antropométricas lusitanas, prevendo multa e prisão para aqueles que ousassem desrespeitar tal determinação. O presente artigo investigou a atuação dos Quebra-quilos no Rio Grande do Norte, destacando vilas e povoações atingidas por esses sediciosos, identificando os grupos sociais partícipes, suas estratégias, e a maneira pela qual as autoridades públicas e militares combateram os revoltosos na citada província. Problematizamos fontes oficiais, correspondências, códices, periódicos de época e ofícios do governo Imperial.
A institucionalização da Matriz de Santa Luzia na cidade de Mossoró-RN
Authors: Santos Arthur
Published: May 2022

Partindo de motivos culturais e religiosos, a maioria dos municípios brasileiros escolhe um santo católico para apadrinhar aquele local, assim, abençoando-os com sua determinada “graça”. A cidade de Mossoró, do estado do Rio Grande do Norte tem como padroeira Santa Luzia. O presente artigo pretende realizar a discussão acerca da institucionalização da matriz de Santa Luzia, no município de Mossoró-RN, e de que forma esse processo esteve relacionado à elevação do povoado à condição de freguesia. A metodologia utilizada consiste na análise de discursos historiográficos produzidos acerca do tema, bem como a utilização de fontes eclesiásticas, como documentos de transações financeiras e construções de capelas, a fim de compreender quais os aspectos socioculturais que contribuíram à consolidação da referida santa como padroeira de Mossoró.
Vencido o New Look: resistências femininas a Christian Dior e as suas modas (Natal/RN, 1948-1953)
Authors: Neto João , Andrade Joel
Published: May 2022

Discute o estilo “new look” desenhado pelo estilista francês Christian Dior em 1947, e como este foi apropriado e criticado pelas moças em Natal durante os anos de 1948-1953, a partir do periódico potiguar Diário de Natal. No caso do francês, suas reportagens destacaram a sua ousadia em relação à criação visto que a situação mundial estava desfavorável à moda em virtude da economia fragilizada, causada pela Segunda Guerra Mundial. Entretanto, as intempéries econômicas não foram suficientes para que Dior suspendesse suas criações, e apresentasse uma nova silhueta, a qual acentuava a feminilidade. Entre as notícias, é possível perceber resistências através do discurso jornalístico, devido os problemas econômicos. Metodologicamente, o estudo constitui-se a partir de consultas ao Diário de Natal, e análise de autores como Gilles Lipovetsky (1989), Medeiros Filho (2014) e Luca (2009), essenciais para a tessitura do estudo em questão. As informações sobre a moda feminina eram refletidas entre 1948-1950 no periódico na seção “Notícias da Moda” e expunha notícias acerca do modismo vigente, marcado pela criação de Christian Dior. A despeito do descontamento das natalenses, no contexto pós Segunda Guerra Mundial, as criações do estilista não foram interrompidas e bem como suas apropriações por tais moças resistentes.
Os caminhos e os desdobramentos da vida, trajetória política e dos discursos e pronunciamentos de Dinarte Mariz
Authors: Bernardo Larisse , Lima Jailma
Published: May 2022

O presente trabalho tem por desígnio traçar os percursos analíticos da trajetória de vida e política, como também das reverberações acerca dos discursos e pronunciamentos a partir da figura eminente de Dinarte de Medeiros Mariz. Político este que se firmou no cenário da política nacional e, que por sua vez, deixou marcas registradas na política potiguar a partir de suas raízes no Seridó norte-rio-grandense. Nessa perspectiva o desenvolvimento da narrativa se dará através de um viés que traçará sua vida política mostrando as alianças criadas, os degraus percorridos por Dinarte, levando em consideração que antes de se tornar figura política, ele foi comerciante e agropecuarista, experiências que corroboraram para o seu fortalecimento na vida política. Assim, a partir desses encaminhamentos busca-se concernir o porquê da manutenção no imaginário político e social em torno da figura pública, uma vez que o mesmo conquistou impulsividade pública ocupando vários cargos, entre os quais, prefeito da cidade de Caicó, governador do Estado do Rio Grande do Norte e Senador da República.

Melhoramentos de São Paulo: intervenções urbanas e as irmandades negras da capital
Authors: Luz Alvaci
Published: May 2022

Partindo da análise do uso corrente do termo “melhoramentos” e da “questão sanitária” nas intervenções urbanas em São Paulo de meados do século XIX e iníciodo XX, o presente artigo se propõe averiguar o quanto o urbanismo, que se configurava como saber, influenciou na redefinição do espaço urbano ao longo de quase um século. Desde o período colonial, as igrejas de irmandades católicas no centro da capital se destacaram como espaços de sociabilidade dos negros, marcando ao longo dos séculos os lugares de manutenção da religiosidade afro-brasileira, das heranças culturais advindas do período colonial e de certa autonomia administrativo-financeira da comunidade negra de São Paulo. No final do XIX e início do XX as igrejas pertencentes a estes grupos sociais, localizadas no triângulo central, bem como o seu entorno, sofrerão significativas intervenções da municipalidade.

Sair da pirâmide e conhecer Além-Nilo: ensino de história do Egito Antigo na Educação Básica
Authors: Braga Bruno
Published: May 2022

Exotismo, mistérios, encantos, pirâmides e faraós, são geralmente coisas que associamos em Educação básica, a aulas de Antiguidade - oriente próximo - Egito Antigo, como se esta civilização/país fosse algo distante, muito diferente se comparado a Antiguidade Clássica. O objetivo desse artigo é apresentar uma proposta de como está pensado o Egito Antigo no livro didático brasileiro, e destacar assim uma possibilidade de novos usos desses textos. De fato, o ensino de história do Egito Antigo no Brasil, segue uma cartilha já estabelecida na qual pouco se faz uso dessa ciência parceira, especializada no assunto que é a Egiptologia. Como a História, essa ciência está em construção, logo, fazer uso de seu discurso em sala de aula, significa fugir do grande rol de nome e datações históricas e focar na realização de uma história participativa, sendo a aula um elo no qual o conhecimento acadêmico expande sua aplicabilidade. Sair da pirâmide e conhecer o além-Nilo significa vislumbrar o Egito Antigo como era e como está atualmente.
