Published: August 2020

ABSTRAKPersyaratan gradasi agregat kasar pada SNI dinyatakan dalam modulus kehalusan. Modulus kehalusan yang disyaratkan untuk agregat kasar adalah 6,0–7,1. Batasan gradasi agregat kasar yang ditetapkan dalam SNI seringkali tidak dipenuhi dalam pelaksanaan pekerjaan beton, terutama jika menggunakan agregat kasar berukuran 40 mm, yang mengakibatkan modulus kehalusan agregat kasar lebih besar dari 7,1. Perlu dilakukan penelitian lebih lanjut mengenai batasan gradasi agregat kasar untuk mengetahui pengaruh yang diakibatkan bila agregat kasar melampaui batasan rentang modulus kehalusan yang telah ditetapkan. Penelitian dilakukan dengan membuat campuran beton menggunakan cara Dreux untuk kuat tekan rencana 30 MPa, nilai slump rencana 30–60 mm dan 60–180 mm, serta modulus kehalusan agregat kasar 6,0; 6,5; 7,0; 7,5; dan 8,0. Hasil penelitian mengungkapkan bahwa campuran beton dengan modulus kehalusan agregat kasar di atas 7,0 tidak berpengaruh terhadap kuat tekan beton, maka batasan gradasi agregat kasar dapat dikembangkan dari 7,1 hingga 8,0.Kata kunci: batasan gradasi, modulus kehalusan, agregat kasar, kuat tekan beton ABSTRACT The requirements of coarse aggregate gradation in SNI stated with the fineness modulus. The fineness modulus required for coarse aggregates is 6.0–7.1. The limitations set in SNI are often not met in the implementation of concrete work, especially if using 40 mm aggregates, resulting in fineness modulus greater than 7.1. Further research on the coarse aggregate gradation limits is needed to determine the effects when it exceeded. The research is done by making concrete mixtures using Dreux's method with concrete compressive strength design  30 MPa, slump design 30–60 mm and 60–180 mm, as well as the coarse aggregate fineness modulus 6.0, 6.5, 7.0, 7.5, and 8.0. The results reveal that concrete mixtures with coarse aggregate fineness modulus above 7.0 do not affect concrete compressive strength, so the coarse aggregate gradation limitation can be extended from 7.1 to 8.0.Keywords: gradation limits, fineness modulus, coarse aggregate, concrete compressive strength

Published: August 2020

El humano ha alterado la mayoría de los ecosistemas a nivel global. La urbanización es actualmente una de las mayores causas de deterioro de los ecosistemas. En este estudio analizamos la diversidad de aves y su posible asociación con atributos ambientales en cuatro ambientes antrópicos: urbano, rural, ribereño y matorral xerófilo, en una zona semiárida del centro de México. En cada ambiente ubicamos 11 puntos de conteo, que visitamos cuatro veces de diciembre de 2014 a abril de 2015. Aplicamos un análisis multivariado para comparar localidades y factores ambientales. La zona urbana presentó una menor diversidad de aves y el resto de los ambientes no tuvo diferencias en su riqueza de especies. La composición de especies presentó cambios de acuerdo con un gradiente de alteración. La alta diversidad beta muestra la necesidad de realizar acciones de conservación en el conjunto de ambientes, especialmente mantener parches de vegetación en zonas urbanas y rurales, así como conservar los ambientes con menos impacto antrópico. Resalta la importancia del ambiente rural por su riqueza de especies, la mayor abundancia en especies nativas residentes, y la mayor riqueza y abundancia de especies migratorias. Estos resultados apoyan la necesidad de realizar acciones de manejo para integrar ambientes alterados en la conservación de la biodiversidad.

The ‘clickers project’ is a University-wide project, designed to provide an inclusive facility for technology-enhanced learning to staff and students.Every level 4 student received a free clicker device. Students were asked to register their clicker using the University’s virtual learning environment (VLE) in order to investigate student engagement with in-class quizzes using clickers. Participation in the clicker registration process was recorded and evaluated as an indication of engagement with classroom technologies.Overall, significant differences in progression and participation in the registration process were observed with respect to ethnicity, gender and non-continuation rates for full-time, first degree entrants. In an accompanying survey, students who were less confident in their in-class responses were more likely to resist working with peers or to give-up more quickly when tackling difficult questions.This paper presents three key elements of the project: First, Kingston University’s inclusive approach in promoting classroom technology, second, analysis of engagement with the clicker registration process, and finally student perceptions of the use of classroom technologies. The objective is to show how classroom technologies can be seen as inclusive tools for feedback, capable of providing early signs of gaps in attainment among learners.

Published: August 2020

Dirgantara Indonesia (PTDI) is the single source producer of the NC212i Aircraft. Almost every Aircraft is delivered to the customer over the deadline date. The existence of waste is believed to be one of causing the late delivery. Based on observations of the 117th NC212i Aircraft assembly line, which is precisely at the fuselage assembly in the paneling group, six wastes are identified: waiting, transportation, overprocessing, inventory, and motion. Waste of overproduction does not occur because PTDI applies MTO (Make to Order) system. These 6 wastes are then processed using Waste Assessment Model (WAM). The ranking result is: first place is 25% for defects, second place is 23% for waiting, third place is 17% for motion, fourth place is 15% for inventory, fifth place is 13% for transportation, sixth place is 8% for overprocessing, and seventh place is 0% for overproduction. Three critical wastes based Pareto principle can be minimized, so the delay of aircraft delivery can be reduced.

Published: August 2020

Wawancara merupakan kegiatan komunikasi melalui proses pertukaran informasi antara reporter dan sumber berita. Banyak wartawan lebih sibuk mencatat pada saat wawancara sehingga hasil wawancara tidak efektif. Oleh karena itu dibutuhkan alat perekam untuk merekam jawaban dari narasumber. Akan tetapi alat perekam dibutuhkan waktu untuk mendengarkan hasil rekaman, kemudian mencatatnya. Padahal dituntut untuk mengumpulkan 3 sampai 4 berita dalam sehari. Dalam ilmu komputer terdapat bidang ilmu yaitu Speech to Text, teori ini akan bermanfaat untuk kondisi tersebut. Speech to text merupakan fitur untuk mengubah suara menjadi teks. Keunggulannya adalah layanan pengenalan suara. Speech to Text berfungsi untuk memanajemen waktu agar lebih efektif. Umumnya kecepatan berbicara dengan kecepatan mencatat berbeda. Sehingga hal tersebut menyulitkan wartawan yang bertugas. Disisi lain, teori ini akan sangat berguna bagi kaum disabilitas. Karena user atau pengguna hanya perlu menggunakan suara untuk melakukan aktivitas mengetik selayaknya orang normal pada umumnya. Dari permasalahan tersebut, dibuatkan aplikasi yang bisa mengubah suara ke dalam suatu teks/tulisan dengan menggunakan bahasa pemrograman Python. Untuk melakukan proses mengubah suara menjadi teks menggunakan modul speech recognition. Uji coba menggunakan 6 sample audio hasil rekaman, didapat bahwa dengan menggunakan bahasa pemrograman Python, mampu mengonversi suara ke tulisan dengan tingkat keberhasilan mencapai 94,75 %.

Preferência dos cirurgiões-dentistas por atendimentos de urgência e emergência frente ao Covid-19
Authors: Franco Amanda Gonçalves , Silva Miranda Fernando , Batista Gonçalves Franco Aline
Published: August 2020

Com o objetivo de conter o avanço da infecção causada pelo Covid-19, a Associação de Medicina Intensiva Brasileira (AMIB), com o apoio do Conselho Federal de Odontologia (CFO), criou o Comitê de Odontologia de Enfrentamento à Covid-19. A parceria divulgou orientações que orientam o atendimento odontológico de cirurgiões-dentistas nos consultórios e dos agentes públicos que atuam em ambiente hospitalar, caso o atendimento seja realmente necessário. Entre as recomendações relacionadas às medidas de biossegurança que os profissionais devem tomar durante os procedimentos odontológicos podemos citar a pré-triagem, para definir se o paciente é infectado e definir se o tratamento a ser feito é de urgência ou emergência odontológica. Além da pré-triagem, tem-se as medidas de biossegurança, como a higiene frequente das mãos; a utilização e descarte correto dos EPI’s, a segurança durante o manuseio dos perfuro-cortantes; a esterilização dos instrumentos e dispositivos e a limpeza e a desinfecção das superfícies. Para facilitar o entendimento por parte dos profissionais dos atendimentos preferenciais, a Secretaria de Saúde definiu os conceitos de urgências e emergências odontológicas. Essa medida visa ressaltar que essas duas são as situações em que os cirurgiões dentistas devem realizar seus atendimentos. Frente ao grande risco de contágio e visto que a transmissão do vírus pode se dar de muitas formas, entende-se assim a necessidade de reduzir os atendimentos odontológicos apenas para os realmente necessários e a importância de serem as medidas de segurança, visto que o atendimento odontológico possui especificidades que representam fatores de risco de contaminação profissional e assim, de propagação da infecção para outros.

Published: August 2020

Comorbidades específicas têm sido associadas com maior risco de manifestações graves e piores prognósticos da infecção por COVID-19, como a hipertensão arterial sistêmica, bem como o uso de bloqueadores dos receptores de angiotensina II e de inibidores da enzima conversora de angiotensina. A fim de elucidar o efeito da hipertensão e do uso desses fármacos na evolução clínica da COVID-19, foi realizada uma revisão sistemática nas bases de dados SciELO, PubMed e Lilacs, com os termos “Hipertensão”, “Hypertension” e “COVID-19”, sendo incluídos 4 artigos. Foram coletados e analisados dados e informações a respeito do sexo, idade, gravidade da evolução da infecção pela COVID-19, em pacientes hipertensos que fazem ou não o uso das drogas em estudo. Foi observado que os hipertensos infectados estão acima de 64 anos, não há predomínio em relação ao sexo, apresentam maior gravidade da infecção, em especial aqueles que suspenderam o uso dos medicamentos. Foi identificado que, apesar da totalidade dos estudos analisados serem consensuais quanto à influência da hipertensão na gravidade da COVID-19, os mesmos são controversos em relação à suspensão ou não dos anti-hipertensivos em foco no tratamento dos pacientes infectados.

Authors: Araújo Igor Gomes de , Morais Arlandia Cristina Lima Nobre de
Published: August 2020

O SARS-CoV-2 é o vírus responsável pela infecção respiratória do trato inferior, também conhecido como síndrome respiratória aguda grave. Considerando as manifestações clínicas graves, estima-se que 20-30% apresentarão complicações a nível cardiovascular e 30-50% a nível renal. Inicialmente o SARS-CoV-2 infecta as nossas células através de receptor da enzima conversora de angiotensina 2 (ECA2 ou ACE-2), dos alvéolos pulmonares. Ocorrendo sensibilização de células de defesa com consequente liberação de citocinas no sangue, intitulada para a patologia como “tempestade de citocinas”, entre elas, as interleucinas 1 e 6 (pró-inflamatórias), fator de necrose tumoral e interferon-γ. Observa-se nesta patologia a ocorrência de eventos de hipercoagulabilidade e isquemia decorrente da hipóxia. Para então reverter essa condição clínica, vem surgindo a hipótese do uso de anticoagulantes na fisiopatologia de pacientes graves com COVID-19. Após resposta imunológica ocorre o evento inflamatório com consequentes danos endoteliais. Os mediadores da inflamação citados anteriormente ativam fatores procoagulantes. Entres eles, fatores extrínsecos e intrínsecos. Partindo de tal premissa, todos os pacientes hospitalizados com COVID-19 devem receber anticoagulantes caso não apresente riscos de sangramento. No entanto, faz-se necessário estudos randomizados com a heparina não fracionada e de baixo peso molecular para comprovação da atividade inibidora do SARS-CoV-2, além de apresentar-se como perspectiva em ocasionarem modificações conformacionais no vírus, tornando-as uma possibilidade farmacológica. A partir dos estudos analisados pôde-se concluir que o emprego de anticoagulantes na fisiopatologia da COVID-19 são bastante eficazes, com relação ao mecanismo de hipercoagulabilidade que a doença promove.

O surto ocasionado pelo SARS-CoV-2, responsável pela doença denominada de covid-19, foi relatada pela primeira vez em dezembro de 2019 em Wuhan, na China e atualmente é considerada um problema de saúde pública global. Até o momento, o teste considerado padrão-ouro para o diagnóstico final da covid-19 é a reação em cadeia da polimerase com transcrição reversa (RT-PCR). No entanto, é possível observar que diversas publicações destacam a possibilidade de falso-negativos no teste de RT-PCR. Entretanto, até à presente data é indicado a realização desse teste para o diagnóstico definitivo da covid-19. Recomenda-se, portanto, ser realizado precocemente para que o resultado seja confiável.

A covid-19 apresenta relação com a síndrome respiratória aguda causada pelo novo coronavírus, vírus de RNA, possuindo alta capacidade de transmissão. O presente estudo objetivou analisar o cenário da taxa de ocupação de leitos decorrente da covid-19 no estado do Ceará, Brasil. Trata-se de estudo descritivo, de análise do cenário da taxa de ocupação de leitos decorrente da covid-19 no estado do Ceará, Brasil. Ressalta-se que muitos dos pacientes aguardam testagem para covid-19. Buscou-se identificar o perfil dos serviços disponíveis na capital, Fortaleza. A coleta dos dados ocorreu no dia 14 de abril de 2020, nos sites IntegraSus e Coe-Covid-19. A atualização do boletim epidemiológico do dia 14 de abril de 2020, apresentou 2.044 casos confirmados, segundo data do início dos sintomas; 1.878 casos novos confirmados, segundo data do resultado do exame, 111 óbitos, 5,43 letalidade, 62 municípios com casos confirmados, 11.954 quantidade de exames e 9.242 casos supeitos. Outros equipamentos de saúde apresentam altas taxas de vagas já em ocupação desde janeiro, antes da chegada do vírus, por demandas de rotina. A maior incidência de internados são do sexo masculino (57,5%) e entre ambos os sexos, acima de 45 anos. Com concentração do número de casos em Fortaleza, 59 internados e 1.794 casos confirmados da doença, seguido de Caucaia (39 casos), Maracanaú (35 casos) e Aquiraz (30 casos). Pode-se concluir um cenário de preocupação diante de poucos leitos disponíveis, face de um possível colapso com a incidência dos casos mais graves da doença que necessitam de suporte adequado.

Decisões críticas no combate à pandemia causada pelo SARS-CoV-2 têm sido realizadas frequentemente com dados e informações ainda incompletas. Enquanto os órgãos pertinentes não solucionam os gargalos no fluxo de informações de vital importância, epidemiólogos e outros pesquisadores devem produzir subsídios técnicos para o enfrentamento da crise contornando essas limitações. No presente estudo, focado no Brasil, comparamos os óbitos pelo SARS-CoV-2, disponibilizados diariamente, com os dados de óbitos por doenças respiratórias e outras doenças nos anos de 2014 a 2018 (os últimos cinco anos completos para os quais os dados estão disponíveis). Adicionalmente, extraímos os sinais temporais anuais dos óbitos por doenças respiratórias para que o período típico de pico na mortalidade por essas doenças  possa ser considerado em cada estado Brasileiro. A porcentagem de óbitos pelo SARS-CoV-2 até o dia 15 de abril equivale a 24% da mortalidade esperada por causas respiratórias no mesmo período, com base em anos anteriores, com grande variação entre os estados (desde o Amazonas, 151%, até o Tocantins, com 3%). Estamos na época típica de pico de mortalidade associada a doenças respiratórias em grande parte do Norte e Nordeste (com exceção de Roraima). Nas regiões Sudeste e Sul, esse pico é mais tardio (junho–agosto). A evolução da pandemia em cada estado dependerá, no entanto, de vários outros fatores, como o comportamento do patógeno – ainda não conhecido suficientemente. Ressaltamos a necessidade de ações para aumento da agilidade na disponibilização dos dados atuais de mortalidade (por diversas causas), para que equipes de pesquisa com diferentes abordagens analíticas possam se somar no combate a este desafio sanitário global.

Published: August 2020

The aim was to study the effectiveness of the use of turmeric extract in the composition of the original rectal suppositories in experimental Crohn’s disease (CD) based on the assessment of the clinical picture and indicators of the immune status.

Materials and methods. The work was performed on 70 rats of the Wistar line. CD was unduced by the rectal administration of a trinitrobenzenesulfonic acid solution, rectal suppositories with 0.000075 mg of curcumin based on an alcohol solution of rhizome extract with turmeric roots were used after 12 hours for 7 days, in the comparison group rectal suppositories with 50 mg of 5-aminosalicylic acid were used (5-ASA). To assess the clinical status, the Disease activity index scale was used, the population spectrum of leukocytes, CD3 + and CD45RA + lymphocytes, the concentration of IgG, IgM, IL-23 on the 3, 5 and 7 days of the experiment were determined.

Results: In CD, the clinical signs of the disease progress from 3 to 7 days, the total number of leukocytes in the blood increases due to monocytes, lymphocytes, including CD3 +, CD45RA +, the concentration of IL-23, IgM, Ig G. Local use of turmeric extract in CD reduces the severity of clinical symptoms on days 5 and 7, restores the total number of leukocytes, lymphocytes, including CD3 +, the concentration of IgM on days 3, 5, 7, and IL-23 on days 5 and 7, partially restores serum concentration of IgG on the 3-rd, 5th, 7th day, IL-23—on the 3-rd day of observation. The eff ect of CD in the composition of rectal suppositories of turmeric extract is comparable to the eff ect of 5-ASA on the 3-rd, 5th, 7th day of observation in relation to the severity of clinical symptoms, the number of leukocytes, lymphocytes, CD3 + in the blood, the concentration of IgM and IgG; less pronounced in relation to the concentration of IL-23 on day 3.

Conclusion. The clinical and immunological efficacy of local application of turmeric extract every 12 hours as part of the original rectal suppositories in experimental CD has been demonstrated, comparable with the use of rectal suppositories with 5-ASA.

Published: August 2020

There are the high incidences of gallbladder cancer in endemic countries for S. Typhi infection. In this regions, the majority of chronic carriers suffer from calculous cholecystitis, that in turn have been indicated as predisposing factor for the development of gallbladder cancer. Stones in a gallbladder represent a sort of platform for the formation of bacterial biofilm. It was shown that human bile activates the synthesis of the third type secretory system (T3SS) responsible for the invasion of S. Typhi into the gallbladder cells that may result in intracellular synthesis of typhoid genotoxin with possible carcinogenic effect. The knowing of the pathogenesis of the development of gallbladder cancer makes target therapy of the disease possible.

The human gastrointestinal tract is more complex in its structure and volume of its functions, an organ, or rather, a system of organs. In addition, the intestinal microbiota, which, in turn, is part of the brain-intestine-microbiota axis, is also included in the process of implementing the tasks of the gastrointestinal tract. In this regard, not only instrumental, such as radio-radiological, ultrasound, endoscopic (with subsequent study of biopsy material) and other research methods are relevant, but also laboratory ones aimed at obtaining information about the microbiome and signal molecules involved in regulatory processes gastrointestinal tract. This literature review is devoted to the analysis of modern research methods for neurotransmitters synthesized by the digestive tract and of diagnostic value.

Hyperferritinemia in patients with COVID-19 is associated with liver dysfunction and an increased risk of the “cytokine storm”. The polypeptide preparation Laennec (6 ml per 350 ml of 0.9% NaCl solution, iv, cap. The first 3 days, from 4 days — 6 ml per 250 ml of 0.9% NaCl solution) was used in 14 patients (age 39–86 years old, 6 men, 8 women) with a long, stagnant course of COVID-19 as a hepatoprotector and immunomodulator as part of complex therapy until a stable remission is achieved. Patients in the control group (n = 14) received only standard therapy. The use of Laennec led to positive clinical dynamics: a decrease in ferritin levels (in men by –282 mcg / l, in women by –80 mcg / l, P = 0.039), an increase in blood oxygenation to the normal range (P = 0.0029), and a decrease in the area of damage lung according to CT data (on average, —10%, P = 0.0027), an increase in the relative content of lymphocytes (+ 8%, P = 0.04), normalization of markers of liver dysfunction (AST, ALT), creatinine and systolic blood pressure (P <0.05). All patients treated with Laennec recovered within 3–15 days after the start of the drug and were discharged with a negative test for the SARS-CoV-2 virus.

Aim: To study the compliance features of patients with coronary artery disease and erosive-ulcerative lesions of the gastroduodenal zone.

Methods: The study included 93 patients: 55 (59%) men and 38 (41%) women. Comorbidity indices Charlson, Kaplan-Feinstein and CIRS-G (Cumulative lllness Rating Scale for Geriatrics) system, anxiety and depression scores were calculated for all patients. The questionnaire Kadyrov R. V. et al. “The level of compliance was used to evaluate patient adherence. Statistical processing was performed using PAST (v. 3.21; Hammer et al., 2001) and MedCalc (v. 13.0; MedCalc®).

Results: All patients are divided into two groups: group I—30 (32%) patients with coronary artery disease with erosive and ulcerative lesions of the stomach and duodenum, group II—63 (68%) patients with coronary artery disease without erosive-ulcerative gastroduodenopathies. We found significant intergroup differences in patients according to the CIRS-G and KAPLAN-FEINSTEIN comorbidity indices.

In patients with coronary heart disease with erosive-ulcerative gastroduodenopathies the level of general compliance and its components was significantly higher than in patients without pathology of the gastroduodenal zone. It should be noted that high compliance according to the questionnaire was observed in 22 (73.3%) patients in group I and in 19 (30.2%) patients of group II (p <0.001), while with a low level of compliance—in 1 (3.3%) in group I and 17 (27.0%) in group II (p = 0.009). The level of compliance did not correlate with age, duration of disease, and comorbidity indices.

Conclusion: In the study group of patients the frequency of erosive and ulcerative gastroduodenopathies was 32%. Patients with ischemic heart disease and erosive-ulcerative gastroduodenopathies are characterized by higher levels of compliance and anxiety.
