Published: June 2021

This systematic review aims to compare the success rate of Endosequence bioceramic root repair material (BCRRM), mineral trioxide aggregate (MTA), and calcium hydroxide for apexification of necrotic immature permanent teeth. Indexed Journals such as Google Scholar, PubMed, Scopus, Cochrane, Research Gate, Wiley Online Library, and other related journals were hand searched from inception till November 2020 and articles were selected for review based on PRISMA guidelines. Of the 410 studies that were identified, 150 articles were selected after title/abstract reading. After full-text reading and based on inclusion and exclusion criteria, 9 studies were finalized for systematic review. Clinical, radiographic success, and the time taken for apical barrier formation were reviewed. All the three materials had almost similar success rate in terms of clinical symptoms, but the time taken for apical barrier formation and also single visit treatment makes MTA and Endosequence BCRRM superior to calcium hydroxide. Studies comparing EndoSequence Root Repair Material and MTA are very limited and need further evaluation in the future.

Published: June 2021

Background:

Periapical extrusion is frequently observed during endodontic therapy. It can lead to acute injury of periapical tissues, resulting in interappointment pain or swelling. The effect is pronounced in teeth with immature apex, which are more susceptible to the extrusion of irrigant. The aim of this study was to evaluate the effect of gravity on the apical extrusion of irrigating solution with different irrigation protocols in single-rooted premolars.

Methodology:

A total number of 80 permanent single-rooted teeth (premolars) with same working length (WL) were divided into two main groups: Group A: Penetration depth of irrigation syringe to 2 mm from the WL and Group B: Penetration depth of irrigation syringe to 4 mm from the WL. Each group was subdivided into four subgroups. (n = 10). The extruded debris and irrigants were weighed, and the data were statistically analyzed by the analysis of variance and the Tukey test.

Results:

Irrespective of the irrigation technique used, the amount of irrigant extruded from the apex showed a statistically significant difference related to the effect of gravity (P < 0.05). There was no statistically significant difference observed between irrigation methods (P > 0.05).

Conclusion:

The degree of apical extrusion of irrigant was dependent on the type of irrigation technique and gravity. Greater caution should be taken during irrigation to prevent postoperative pain.

Published: June 2021

Introduction:

Impression making is an integral part of prosthetic dentistry. Development of material science has allowed integrating qualities of hydrophilic polyether and hydrophobic polyvinyl siloxane into a newer hybrid material, vinyl polysiloxane (VPS) ether. This study was aimed to compare the VPS ether with the polyether and polyvinyl siloxane in terms of accuracy and dimensional stability.

Materials and Methods:

Stainless steel dies with the American Dental Association specification 19 were made. Die has three horizontal and two vertical lines which are used for taking the impression. Two cross-points at the junction of the vertical lines with line 2 were marked as x and x' and served as beginning and end points of measurements for dimensional accuracy. Accuracy was evaluated 30 min after making each impression. If at least two of the three horizontal lines were reproduced continuously between cross-points, this impression was considered satisfactory. The specimens are poured with Type IV gypsum product and allowed to set completely for 24 h. Then, dimensional stability was measured in the model by measuring the distance between the two lines and comparing the distance with the measurement of line on metal die, which was used to make the impression.

Results:

The mean value obtained for light- and medium-bodied VPS ether was 0.05370 and 0.05330 and for light and medium-bodied polyvinyl siloxane was 0.06370 and 0.07150, respectively. The mean value for polyether monophase was 0.06430. Two-way ANOVA and post hoc test showed statistical significance.

Conclusion:

The newer VPS ether material showed good surface detail reproduction and dimensional stability when compared with polyvinyl siloxane and polyether.

Published: June 2021

Objective:

Reproducibility of qualitative changes in histopathological diagnosis involving narrow variation is often challenging. This study aims to characterize the histological fibrotic events in detail so as to derive an in-depth multiparametric algorithm with individually quantified histological parameters for effective monitoring of the. disease process in oral submucous fibrosis and for potential therapeutic targets for early intervention.

Methods:

Formalin fixed paraffin embedded (FFPE) blocks of oral submucous fibrosis (OSMF), were taken and sections were stained with Hematoxylin & Eosin stain and Masson Trichrome stain. Photomicrographs were assessed for various morphometric parameters with Image J software version 1.8. Linear Regression was used to model the relationship using Inflammatory Cell Count, Extent of Inflammation collagen stained area, Epithelial thickness integrated density of collagen, MVPA, Area, Perimeter, were taken as variables.

Result:

Inflammatory cell count and the extent of inflammation also decreased with increasing grades of OSMF. Collagen proportionate area, integrated collagen density and epithelial thickness were compared among different grades of OSMF. Grade IV OSMF had greatest mean collagen proportionate area, highest integrated collagen density and lowest epithelial thickness when compared to other grades of OSMF. Linear regression model revealed smaller variation between Grade I to Grade II. Whereas Grade II to Grade IV exhibited larger variation suggestive of increased growth rate and all the coefficients were found to lie within 95% confidence limits

Conclusion:

Diagnostic algorithm with multiparametric regression model were derived and combinatorial therapeutic approaches have been suggested for more effective management of oral submucous fibrosis

Türkiye'de Sığır Gübresinden Biyoyakıt Olarak Biyogaz Üretiminin Potansiyeli ve 2030 ve 2053 Yıllarında Karbon Emisyonlarının Azaltılmasına Öngörülen Etkisi
Authors: ATELGE Raşit
Published: June 2021

Dünyadaki artan nüfus ile birlikte enerji talebi de aynı eğilimle artmaktadır. Artan enerji talebini karşılamak için fosil yakıtlarının sınırlı olması ve yakılması sonucu çevre sorunlarına neden olmaları, araştırmacıları yenilenebilir enerji kaynaklardan bu talebin karşılanması için motive etmektedir. Biyogaz, yenilenebilir enerji kaynaklarından olup atıkların enerjiye çevrilmesiyle yenilenebilir enerji kaynağı üretmenin yanı sıra atıkların bertaraf edilmesiyle atmosfere salınacak gazların azaltılmasında da katkı sağlamaktadır. Bu çalışmada, biyogaz üretimi için besin kaynağı olarak sığır gübresi kullanılarak anaerobik parçalama (AP) işlemi uygulanmıştır. Mezofilik şartlarda (37oC±1) biyokimyasal metan potansiyeli testi yapılarak, spesifik biyogaz ve metan üretimi 236 ± 15 mL Biyogaz/g VS ve 133 ± 3 mL CH4/g VS olarak elde edilmiştir. Deneysel çalışma sonuçları 2018 yılı Türkiye genelindeki sığır sayısıyla ilişkilendirilerek Türkiye’deki sığır gübresinden biyogaz üretim potansiyeli hesaplanmıştır. Bu potansiyelin elektrik enerjisi üretiminde kullanılmasıyla milyon ton CO2 eşdeğerinde sera gazı emülsiyonundaki azalma belirlenmiştir. Potansiyel bu enerjiyi kömür kullanımı yerine biyogaz kullanılarak üretilmesi durumunda 23,26 milyon ton CO2 eşdeğerinde gazın atmosfere salınımın azaltılacağı ortaya konmuştur. Ayrıca, ARIMA model kullanılarak 2023, 2030 ve 2053 yılları için sığır gübresinden biyogaz üretimi potansiyeli tahminlemesi yapılmıştır. ARIMA modeline göre, üretilecek potansiyel biyogazın elektrik enerjisine dönüştürülmesi ve elektrik üretimi için kömür kullanımının azaltılmasıyla birlikte 2023 yılı için 32,62, 2030 yılı için 44,22 ve 2053 yılı için 70,74 milyon ton CO2 eşdeğerinde gaz emülsiyonu salınımında azalma tahmin edilmektedir.

Authors: ASADI AMENEH , AMERI REZA , NOROUZI MORTEZA
Published: June 2021

Let R be an (m,n)-hyperring. The Γ∗-relation on R in the sense of Mirvakili and Davvaz [?] is the smallest strong compatible relation such that the quotient R∕Γ∗ is an (m,n)-ring. We use Γ∗-relation to deﬁne a fundamental functor, F from the category of (m,n)-hyperrings to the category of (m,n)-rings. Also, the concept of a fundamental (m,n)-ring is introduced and it is shown that every (m,n)-ring is isomorphic to R∕Γ∗ for a nontrivial (m,n)-hyperring R. Moreover, the notions of partitionable and quotientable are introduced and their mutual relationship is investigated. A functor G from the category of classical (m,n)-rings to the category of (m,n)-hyperrings is deﬁned and a natural transformation between the functors F and G is given.

No caso específico brasileiro o crescimento do rádio a partir dos anos 40 e da televisão se afirmando nos anos 1970 contribuiu para sua maior aproximação da política e consequente uso por grandes lideranças em torno de projetos voltados para conquista e manutenção de poder. Neste estudo pretende-se compreender a influência midiática na política brasileira logo após o processo de redemocratização de forma específica na eleição presidencial de 1989 que contrapôs Fernando Collor de Melo de Luis Inácio Lula da Silva.

Authors: Pellin Daniela , Engelmann Wilson
Published: June 2021

A nanotecnologia é um ramo eficiente das inovações. É a área da técnica que melhor atende às necessidades da globalização humana, econômica, social e política, diante da peculiar condição de agregar valor à industrialização de bens e serviços e o fortalecimento dos Estados. Entretanto, estão presentes os riscos ao homem e ao ecossistema que necessitam ser geridos de forma eficiente e responsável durante o ciclo de vida de um nanomaterial. A pesquisa enfrenta como tema, a construção adequada da NanoÉtica nacional. A problemática está na ausência de comprometimento social e gerenciamento eficiente dos riscos nanotecnológicos por parte dos agentes econômicos, assim como, a hipótese está na emancipação da governança corporativa pela governamentalidade do bem para a gestão eficiente, responsável e nanodemocrática. Para esse desiderato, o objetivo geral é inserir a governamentalidade na ética empresarial, e específico, emancipar a governança corporativa para inseri-la em uma visão estruturante da NanoÉtica. Como metodologia, o ensaio se socorrerá da coleta de dados, da revisão bibliográfica interdisciplinar e da análise sistêmica-construtivista.

Authors: Carvalho Alessandro Clementino , Paiva Priscila Henrique Moraes
Published: June 2021

Com mais de 42 milhões de casos de COVID-19, em 20 de outubro de 2020, as mortes em decorrência do SARS-CoV-2 contabilizam a marca de aproximadamente 1,1 milhão de óbitos no mundo. A elevada propagação e patogenicidade do SARS-Cov-2, a inexistência de um tratamento efetivo e a imunização preventiva geram instabilidade política, financeira e psicológica mundialmente. Apesar disso, inúmeros estudos têm sido realizados no intuito de compreender melhor a doença, sobretudo os fatores que predispõem a sua forma grave. Desse modo, o presente artigo tem como propósito realizar uma revisão de literatura de pesquisas publicadas recentemente sobre os elementos relacionados à suscetibilidade no desencadeamento da forma grave da COVID-19. Sabe-se que aproximadamente 15% dos pacientes infectados pelo vírus necessitam de cuidados especiais e como consequência a internação. Apesar de cada indivíduo possuir uma resposta imunológica diferente perante a patologia, fatores como grupo sanguíneo, presença ou não de comorbidades, características genéticas associadas ao sexo, elevada expressão do gene ACE-2 e até tolerâncias distintas a falta de oxigênio serão abordados e discutidos nessa revisão, proporcionando contribuições para a comunidade acadêmica em desenvolvimento de ações com embasamento científico responsável.

Authors: Gil-Ramírez Hernán , Guilleumas-García Rosa María
Published: June 2021

Analysis of social networks has become of great interest to researchers from different areas, including educators, due to Twitter’s growing importance as a space for discussion and dissemination of knowledge and opinions. This reality demands the development of analysis processes that allow to know the topics of interest in the network, the positive or negative feelings in relation to those topics and who the network influencers are. Those objectives guided this research work and in order to achieve them, we developed a methodological proposal for sentiment analysis of tweets. This article describes the process followed, which involved 1) detecting the structure of the communication network, 2) calculating the general metrics, 3) representing the communication network, 4) identifying and analyzing the clusters, 5) calculating their metrics as well as those of the individual nodes and 6) establishing the polarity of the posts published in the network. This paper also describes the methodoly followed to identify trends and topics of interest in the hashtags and web domains included in the tweets. The proposal for analysis presented here is intended to help researchers interested in the field of social networks, to understand the complex interactions that take place in these environments and the way in which information is disseminated, valued and converted into topics of interest thanks to the network users’ actions.
40 años de estructuras de suelo reforzadas con geomalla de polietileno de alta densidad (HDPE): Los muros más altos de Latinoamérica a los Emiratos Árabes Unidos
Authors: Doulala-Rigby C. , Pérez A.
Published: June 2021

El primer uso del refuerzo de geomalla polimérico de polietileno de alta densidad (HDPE) en ingeniería civil fue reforzar y construir un muro de suelo reforzado provisional de 2,5 m de alto en la fábrica de carbón Newmarket / Silkstone en West Yorkshire, Reino Unido en 1980, justo un año después de que la primera geomalla polimérica fuera inventada por el Dr. Mercer en 1979 en Blackburn, Reino Unido. Desde entonces, los sistemas de muros de retención de suelo reforzado (RSRW, por sus siglas en inglés) se han utilizado ampliamente en todo el mundo para formar diversas geometrías, alcanzar alturas cada vez mayores y cumplir diversas funciones, desde campos de golf al aire libre hasta pistas de aeropuertos. Este documento ofrece una visión histórica de cómo han evolucionado los sistemas RSRW en los últimos 40 años, sus componentes y mecanismos básicos, y presentará los estudios de caso de 2 muros de suelo reforzado de gran altura, construidos con geomallas poliméricas de polietileno de alta densidad. Un muro en Guatemala de 20m de altura y otro de 60m (escalonado) de altura en los Emiratos Árabes Unidos.

Authors: Huang Yu Liu, Junge , Wang Jihao
Published: June 2021

The monitoring systems of various industries have various types and different structures. There are problems of “data chimney” and “information islands”. Monitoring data is difficult to be effectively utilized and cannot provide reliable data information to support for environmental security. In this end, an environment monitoring system based on micro-service architecture is designed. The information management and automatic monitoring business systems are unified into a flexible, robust and efficient system platform to adapt to the big data analysis and the mining applications. Using Hadoop to build environment monitoring big data platform, distributed storage, selective extraction and efficient calculation of the massive environment monitoring data can be achieved. By integrating the detection and monitoring data of the ecological environment and in-depth mining it, a neural network model is established to automatically identify potential safety hazards and recommend corresponding treatment measures, so to assist in the comprehensive research and scientific decision-making of environmental safety and promote intelligent management of safety.
