Vulnerabilidades e incertidumbres entre el desarrollo y el Buen Vivir: Riesgo social en zona petrolera
Authors: Murgida Ana
Published: April 2021

From a perspective of the anthropology of risk and disasters, we investigate the production and consolidation of successive vulnerabilities that occur during the social construction of risk through industrial pollution in the northern oilfields of the province of Neuquén in Argentine Patagonia. The case of the Mapuce community of Nehuen Kura provides the line of analysis which integrates in a historical manner the different life aspects of communities in environments degraded, at times, to a condition of a "sacrificial area". We describe the direct effects of extractive intrusions on the natural and constructed environment, as well as the effects of State directives that derive from prevailing models of development and access to common goods by aboriginal communities and extractive industries. We develop a critical ethnography and employ multiple methodological strategies to reveal the forms of control -or its absence- in the face of the slow and steady generation of a disaster, and expose the cultural expressions of suffering caused by the effects of disaster and risk. This allows us to detect qualitative variables and indicators that permit the integration of subjectivity through a category of "sacrifice" which accompanies local adaptive strategies. In this way, we contribute to the discussion on the definition and uses of social vulnerability as it relates to the disaster risk associated with development projects.
Resultantes ambientais da drenagem de superfícies brejais e lacustres na baixada Campista, Norte do Estado do Rio de Janeiro, Brasil

Interventions in river environments are measures taken by men since they have become sedentary. In the Campista lowland, the main objective of these interventions was to create the ideal conditions for the establishment of the sugar agro-industry and the expansion of sugarcane cultivation areas. To achieve this, a wide drainage of the wetland and lacustrine surfaces of the region was carried out through the deployment of a network of artificial channels. Currently, it is clear that these structures acted so that they intensified the consequences of environmental disasters deflagrated by floods and droughts. Given this context, this work presents a historic review of this drainage process, as well as assessment of the environmental consequences of such interventions, especially those regarding the hydrology of river environments that characterize the low courses of rivers, and the worsening of extreme hydrological events which eventually cause environmental disasters.

Published: April 2021

Klasik Türk edebiyatında kullanılan nazım türlerinden biri de şikâyetnâmedir. Manzum veya mensur kaleme alınan şikâyetnâmelerin manzum olanları kıt’a, terci’-i bent, murabba, kaside, müseddes gibi çeşitli nazım şekilleriyle oluşturulur. Manzum şikâyetnâmeler; divanların, mecmuaların içinde yer alabileceği gibi başka eserlerin içinde de bulunabilir. Şikâyetnâmeler, gerek şairlerin psikolojini yansıtması gerek dönem ve muhitle ilgili bilgiler vermesi açısından önemli birer eser hüviyetindedir.
Edebiyatımızda kaleme alınan manzum şikâyetnâmelerden biri 16. yüzyıl divan şairlerinden Fevrî’nin Şikâyetnâme’sidir. Fevrî Divanı’nda yer alan Şikâyetnâme, kaside nazım şekliyle yazılmıştır. Fevrî, medreseden mezun olduktan sonra tayininin gecikmesi sebebiyle bu Şikâyetnâme’yi kaleme almış ve II. Selim’den yardım istemiştir. Bu çalışmada Klasik Türk edebiyatında şikâyetnâme türünün genel özellikleri, diğer türlerle ilişkisi gibi hususlardan sonra kitap veya makale çalışmasına konu olan manzum şikâyetnâmelerle divan taramaları sonucunda tarafımızdan tespit edilen manzum şikâyetnâmeler bir tabloyla sunulmuş ve şu ana kadar tespit edilen manzum şikâyetnâmeler muhteva ve şekil yönünden değerlendirilmiştir. Makalenin diğer bölümlerinde ise Fevrî’nin hayatı, edebî şahsiyeti, eserleri ile ilgili bilgiler verilmiş, Fevrî Divanı’nın iki nüshası üzerinden Şikâyetnâme transkrip edilerek; Fevrî’nin Şikâyetnâme’sinin muhteva ve şekil açısından değerlendirilmesi ve diğer manzum şikâyetnamelerle mukayesesi yapılmıştır.
KLASİK TÜRK ŞİİRİNDE “FİTNE” KELİMESİNİN “KÖPEK” ANLAMIYLA KULLANIMINA DAİR
Authors: KARAKUŞ Yasemin
Published: April 2021

Sözlüklerde en genel şekliyle “karışıklık, kargaşa” olarak anlam verilen fitne, insan ilişkilerinde var olması, kutsal kitaplarda geçmesi ve çeşitli inanışlara da konu edilmesi sebebiyle klasik Türk edebiyatı metinlerinde sıklıkla rastladığımız bir kelimedir. XVI. yüzyılda Latîfî tarafından yazılmış olan Tezkiretü’ş-şuarâ ve Tabsıratü’n-nuzemâ isimli şairler tezkiresinde, bu kelimenin bilinen anlamlarının yanı sıra, halk arasında “küçük köpek” anlamında kullanıldığı bilgisi yer almaktadır. Bugüne kadar yapılan muhtelif çalışmalarda özellikle “rakip” ile birlikte geçtiği beyitlerde yorum yoluyla çıkarılabilecek olan fitne kelimesinin köpek anlamı, Latîfî sayesinde delillendirilmiş olmaktadır. Bu makalede, tezkiredeki ilgili bölüm ışığında fitne kelimesinin bilinen anlamları dışında “köpek” anlamıyla da kullanıldığına işaret edilmekte, Latîfî’nin verdiği bilgiler doğrultusunda kelimenin klasik Türk şiiri metinlerindeki kullanımları üzerinde durulmaktadır.
BİR ANLATIM TARZI OLARAK MESNEVİ’DE BAZI ÂDET, İNANIŞ VE KABULLER

Published: April 2021

Mevlânâ’nın 25.700 beyitten oluşan Mesnevî’si, üslubu, hikâyeleri, meselleri ve örnekleri ile çok beğenilen ve okunaneserlerden biri olmuştur. Muhtevası çoğunlukla ahlakî ve tasavvufi konulardan oluşması itibarıyla hemen tamamen başucukitaplarından olmuştur. Dolayısıyla Farsça kaleme alınan bu eserin pek çok tercüme ve şerhi yapılmıştır. Yine Mevlevîlikgeleneğinde Mesnevî okumaları, rutin dersler ve sohbetlerden olmuştur. Mesnevî’yi önemli yapan, onun muhtevası kadarüslubunun da çekici ve etkileyici olması yönüdür. Özellikle kahramanlarının hayvan figürleri olduğu hikâyeleri başta olmaküzere bütün hikâyeleri, hayatın içindeki gerçekleri ifade etmenin yanı sıra manevi ve soyut hususları anlatmada çok etkiliolmuştur. Belki de Mesnevî’yi çok tutulan ve sevilen bir eser konumuna getiren onun bu yönüdür. İç içe girmiş bu hikâyeler,sonucu uzadıkça okuyucu da bir merak ve beklenti hissi uyandırmaktadır.Hikâye tekniğinin etkileyiciliği yanında Mesnevî’nin diğer bir üslup özelliği ise önceki dönemlerin ve Mevlânâ’nın kendidöneminin âdet, inanış ve genel kabullerinin yaygın bir şekilde kullanılmasıdır. Bu durum, şiirdeki estetik yönün yanı sıraokuyucuyu dönemin söz konusu kültürel ögelerinden haberdar etmesi itibarıyla da çok büyük önem arz etmektedir. Bugünbelki de hiçbir zaman bilinemeyecek âdetler, inanışlar, ritüeller ile ilgili okuyucu bilgi sahibi olmaktadır. Şüphesiz Mevlânâ, buörnekleri kişilerin bunlardan haberi olsun amacından önce soyut ve anlaşılması zor olan dinî, ahlakî, tasavvufî hususlarındaha iyi anlaşılıp kavranması noktasında kullanmakta idi. Bu çalışmada, Mesnevî’de geçen söz konusu örneklerden bazılarıüzerinde durulacaktır.

İMLASI PROBLEMLİ NÜSHALAR ÜZERİNDEN TENKİTLİ METİN KURMA HAKKINDA DEĞERLENDİRMELER: KÜNHÜ’L-AHBÂR II. RÜKÜN ÖRNEĞİ
Authors: DONUK Suat
Published: April 2021

El yazması kitaplar çoğaltan müstensihlerin bazıları görevlerini suiistimal edebilmiştir. Bu tür müstensihlerin istinsah ettiği nüshalarda metnin pek çok yerinin imlası herhangi bir anlam yüklenemeyecek kadar kötü olabilmektedir. Osmanlı döneminde yazılmış eserlerden bazıları sadece bu nitelikteki yazmalarla günümüze kadar gelebilmiştir. Gelibolulu Mustafa Âlî’nin Künhü’l-ahbâr adlı eserinin II. Rükün’ü üç nüsha ile günümüze intikal etmiştir. Bu nüshaların müstensihleri pek çok kelimeyi yanlış yazmış, başlıkları metin dışı bırakmış, cümle ögelerinin yerlerini değiştirmiştir. Seciyi bozmuş, metne gereksiz sözcük veya ibareler dahil etmiştir. Bir naşirin edisyon kritiğin bilindik kaideleriyle bu vasıftaki nüshalar üzerinden kuracağı tenkitli metin müellifin elinden çıkmış orijinal metinden farklı olacaktır. Ancak naşir, çalıştığı eserin muhtevası hakkında araştırmalar yaparak, klasik Osmanlı nesir dili bilgisini ve günümüzün teknolojik imkanlarını kullanarak metnin pek çok kısmını tamir veya tashih edebilir. Tıpkı bir arkeolojik, kodikolojik veya mimari restoratör gibi çalışarak kurtardığı eserin tenkitli metnini müellifin elinden çıkmış haline yakın bir surette neşredebilir. Bunun için eserin kaynaklarına ulaşmalı, iki yerdeki anlatımları mukayese etmelidir. Nüshalarda boş bırakılan başlık ve diğer kısımları kaynak eser yardımıyla tamamlamalıdır. İmlası bozuk kelime, terkip veya ibareleri kaynaktaki anlatımlara göre müellifin üslubu ve çağın dil hususiyetleriyle tamir etmelidir. Mevcut nüshalarda yanlış yazılmış özel isimleri kaynak eser veya başka bilgi mecraları doğrultusunda tashih etmelidir. Kaynak eserlerin çoğu Arapça veya Farsça olacağı için metin neşircisinin bu iki dildeki kaynaklardan istifade edebilecek yetkinlikte olması önemlidir. Bu makalede Künhü’l-ahbâr II. Rükün örneği üzerinden imlası problemli nüshalar esas alınarak tenkitli metin kurulurken rastlanabilecek özel durumların tespiti yapılmış, karşılaşılabilecek problemler sıralanmış ve bu problemlerin halli için tercih edilebilecek bazı çözüm yolları önerilmiştir.
Sociabilidade e aprisionamento na sociedade industrial
Authors: Magalhães Lília Gonçalves , Tavolaro Sergio
Published: April 2021

As reflexões de Max Horkheimer, Theodor Adorno, e Herbert Marcuse significaram um marco na produção sociológica do século XX. Autodenominando-se intelectuais condutores de uma “Teoria Crítica”, os principais pesquisadores e pensado- res do Instituto de Pesquisa Social passaram, a partir da década de 60, a ser designados de Escola de Frankfurt. Levando às últimas conseqüências as idéias de “burocratização” e “proeminência da racionalidade instrumental” nas sociedades industriais avançadas, tais reflexões chegaram ao ponto de desqualificar qualquer possibilidade de emancipação do homem moderno, diagnóstico, aliás, muito caro às suas fortes raízes marxistas. Mas, qual seria o perfil dessa aprisionante sociabilidade moderna? Que dimensões restariam ao homem contemporâneo? Como seria seu relacionamento com o mundo natural a sua volta? Essas são algumas das questões que norteiam o presente artigo.

Authors: Troquez Marta Coelho Castro , Guarizzo da Silva Marcela
Published: April 2021

Este artigo analisa políticas e práticas que orientam a educação escolar de crianças indígenas em escolas não indígenas. Os procedimentos metodológicos são de análise documental e de pesquisas qualitativas do tipo estudo de caso. Para tal, discute a legislação educacional brasileira para o atendimento da diferença e as práticas pedagógicas em curso. Os resultados mostram que muito ainda está por ser feito na direção da realização de uma educação inter/multicultural que atenda aos reclames da “educação para todos”. São necessárias políticas públicas mais efetivas para que se criem as condições que garantam o cumprimento das leis e a execução de práticas pedagógicas inter/multiculturais.

Memória e (re)existência: a trajetória intercultural da Ação Saberes Indígenas na Escola
Authors: Kaingang Bruno Ferreira , Mendes de Menezes Magali , Bergamaschi Maria Aparecida
Published: April 2021

A Ação Saberes Indígenas na Escola produz movimentos importantes na direção da escola indígena sonhada. O presente texto narra a intensidade, as contradições, alegrias e dores da relação entre agentes da universidade e das comunidades Kaingang e Guarani que participam deste programa. A reflexão, de autoria de um professor formador Kaingang e de duas professoras não indígenas coordenadoras institucionais da Ação na Universidade Federal do Rio Grande do Sul, permeou também as vivências aqui relatadas e suas contribuições para compreender os sentidos da interculturalidade nos diálogos, no trabalho nas escolas indígenas, nas comunidades e na universidade. O debate sobre a afirmação/recuperação das línguas, a elaboração dos materiais didáticos, as reflexões sobre a escola indígena e a organização das lutas por meio do espaço desta Ação reverberam em aprendizagens aqui narradas, como memória e (re)existência da caminhada intercultural.
A política de alfabetização bilíngue: histórico, ações para a formação de professores indígenas e a produção didática
Authors: Faustino Rosangela Célia , Gehrke Marcos , Novak Maria Simone Jacomini
Published: April 2021

Seguindo estratégias internacionais desenhadas desde o início do século XX, há no Brasil uma política de Educação Escolar Indígena, fundamentada na interculturalidade, com foco na alfabetização bilíngue. Porém, considerando a diversidade sociolinguística do país, a histórica política de integração e, mais recentemente, o reconhecimento aos processos próprios de aprendizagem, os programas de alfabetização bilíngue requerem iniciativas locais, articuladas com a formação de professores que resulta em produção de recursos pedagógicos diferenciados. Neste texto, apresentamos um histórico da política de alfabetização bilíngue discutindo documentos e encaminhamentos que culminaram na criação da ação Saberes Indígenas na Escola, inaugurando uma produção didática elaborada pelos professores. Os resultados mostram que a produção de materiais nas próprias comunidades, além de considerar as variações dialetais, oportuniza a criação de fecundos espaços de diálogos e pesquisas dos professores indígenas entre si, com sábios mais velhos, envolvendo jovens e crianças sobre questões culturais e ensejando, ainda, diálogos sobre ensino e aprendizagem escolar na comunidade.
Pinturas faciais dos Boe Bororo: algumas considerações visuais a partir de pesquisa etnográfica, netnográfica e bibliográfica
Authors: Sarmento Nogueira José Francisco , Marido Kiga Neimar Leandro
Published: April 2021

Um dos aspectos mais relevantes da riqueza cultural do povo Boe Bororo é a expressão artística, que exibe uma exuberância e sofisticação estética muito própria. Este trabalho iconográfico faz uma delimitação em uma destas expressões, que é a pintura facial. Para isso, este trabalho, de forma introdutória, apresenta a história deste povo e suas divisões parentais, também chamadas de clãs, para que o leitor possa entender a lógica das divisões que esta arte assume em seu contexto cultural. É importante ressaltar que não se trata de uma pesquisa finalizada, pois a grandeza destas pinturas ainda não foram totalmente identificadas. Ela parte de um trabalho Etnográfico, Netnográfico e Bibliográfico, construído por um designer Boe Bororo e por um designer “braedog” (não indígena). Optou-se por utilizar o recurso de ilustração[1] digital para as representações visuais.
Integrating Servqual-Kano-QFD for Social Insurance Service Quality Improvement in Surabaya
Authors: Pratiwi Dwi Dini
Published: April 2021

For companies engaged in the service-providing sector, good service by meeting customer's desires and needs is a must in order to thrive competitively. This case study was conducted on service provided by the government social insurance company engaged in traffic accident insurance services in Surabaya. As an industry that provides service, customer satisfaction is of importance in order to gain trust from the public, reduce negative opinion in public, and support the objective of good governance. This study integrated the SERVQUAL-Kano method to evaluate customer satisfaction concerning 18 service attributes related to service provided by the social insurance company. Further efforts were then made to find solutions for service attributes with low satisfaction scores by using the Quality Function Deployment (QFD) method. Therefore, the results can help to improve the quality of service. The results were in the form of a priority improvement design for strategic decision recommendations that can be implemented by the company to increase customer satisfaction.
Convalescent plasma, political narrative, and public health ethics in the Covid-19 pandemic
Authors: Agrawal Simran , Agarwal Anup , Jain Yogesh
Published: April 2021

Convalescent plasma therapy emerged as an early experimental therapy for the treatment of Covid-19. However, despite limited data regarding its safety and efficacy, the therapy was extensively publicised by multiple politicians as a cure. We analyse the impact of this political narrative around medical therapeutics on the pandemic using the coherentist model of public health ethics. The clinical benefits of the therapy are evaluated in terms of reduction in mortality and disease progression as compared to the potential transfusion-related adverse events. Political advocacy of therapeutics might hamper the autonomy and decision-making of individuals and institutions. Marketing and monetisation of convalescent plasma might cause inequitable distribution and unregulated use. It also creates an economic burden on the government and healthcare which should be justified by the additional cost/effectiveness ratio of the therapy. This article exemplifies the inadvertent effects and ethical challenges following political narratives about medical therapeutics and the importance of involving ethics in designing policies concerning public healthcare.

Authors: Tkachenko Dmytro , Krush Ihor , Mykhalko Vitalii , Petrenko Anatolii
Published: April 2021

This paper contains a review and analysis of applications of modern ma-chine learning approaches to solve sleep apnea severity level detection by localization of apnea episodes and prediction of the subsequent apnea episodes. We demonstrate that signals provided by cheap wearable devices can be used to solve typical tasks of sleep apnea detection. We review major publicly available datasets that can be used for training respective deep learning models, and we analyze the usage options of these datasets. In particular, we prove that deep learning could improve the accuracy of sleep apnea classification, sleep apnea localization, and
sleep apnea prediction, especially using more complex models with multimodal data from several sensors.
Use of Kemeny median in the algorithm of forming recommendation
Authors: Zhurakovska Oksana , Kochubey Illa
Published: April 2021

The relevant nowadays question of development of the algorithmic support of recommender systems is considered. The article is devoted to the solution of the problem of forming recommendations to new users, which is based on the ideas of transition from the matrix "user-object" to the ranking of objects and the formation of recommendations to the
user of the active cluster based on the construction of the resulting ranking, which is a Kemeny median on a set of rankings. The choice of Kemeny
median as the resulting ranking and the choice of algorithm for its construction are justified. To reduce the complexity of calculations, it is suggested to perform aggregation of information and to use it in forming of
ranking recommendations, which are based on a set of "generalized experts" for this cluster. The efficiency of the developed algorithmic support was studied and the results and recommendations were given.

Published: April 2021

This paper analyses the definition of inverse and direct problems in engineering dimensional chains calculation based on discrete analogue data and the methodologies for solving these problems. It is shown that the direct dimensional chains calculation, which belongs to the
class of inverse boundary value problems in a stochastic formulation, can
be transformed into multi-criteria problems of stochastic optimization with mixed conditions. The new multi-step solutions search methodology for these problems is based on non-linear robust estimation methods. It can be achieved through hierarchical two-level decisions synthesis scheme development. At the first step, this scheme includes identification of surrogate models (in the form of regression equations). At the second step, the
effective robust estimates are computed to determine unknown values; estimations of unknown quantities are carried out under a priori and parametric data uncertainties. Results of calculations of inverse and direct problems in engineering dimensional chains for two-stage axial compressors are presented. They were obtained using interactive computer systems for decision-making support “ROD&IDS”.
Interaction of models with real objects as a way to improve augmented reality
Authors: Bezpalko Oleksandr
Published: April 2021

Unlike a purely virtual world, it is much more difficult for the user to believe in the reality of augmented reality objects. Due to the lack of proper lighting or shadows, the object may appear to be floating in the air, detached from the real objects around it. One obvious problem with augmented reality is that a virtual object appears remote from the real object, but it still appears in front of it. An approach is
proposed that will allow the interaction of real and virtual objects. Both real and virtual objects can be moved and rotated in the scene, preserving overlaps. A virtual object can also be placed in front of or behind a
real object relative to the camera, which decides whether or not to overlap. The proposed algorithm consists of five stages and the system architecture. The evaluation is based on five defined criteria. Results and ways
of improvement for the future research are presented.

Progressing-Cavity-Pump Configuration Addresses Operational Challenges
Authors: Carpenter Chris
Published: April 2021

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 201130, “Novel Progressing-Cavity-Pump Configurations Address Operational Challenges,” by Lonnie Dunn, SPE, Ryan Rowan, and Abhishek Prakash, Lifting Solution, et al., prepared for the 2020 SPE Virtual Artificial Lift Conference and Exhibition-Americas, 10-12 November. The paper has not been peer reviewed.

While downhole progressing-cavity-pump (PCP) designs provide options for end users, the numerous products available, combined with a lack of industry standardization, can make selection and application challenging. The complete paper provides an overview of the development of a PCP concept and implementation, which is not included in this synopsis, and then summarizes two novel PCP configurations deployed to address specific operational challenges.

Design and Manufacturing, Configuration 1

A novel PCP configuration was developed from phased design trials and experience in cold heavy-oil production with sand (CHOPS) wells. This configuration uses a modified rotor to create alternating sections of contact and noncontact within a conventional stator (Fig. 1). The rotor is landed in the stator and operated until there is a performance decline. Then, the rotor is repositioned to move the active section of the rotor into the areas of the stator where there originally was no contact and, as such, normally no associated damage. Keeping the length of the alternating sections short simplifies the surface rotor positioning process, allowing it to be performed riglessly. The main benefit of this is that, rather than having to pull the rod string and run a different rotor, the same rotor is used and repositioned through lifting of the rod string at surface.
Technology Focus: Formation Damage (March 2021)
Authors: Fleming Niall
Published: April 2021

Formation damage has received significant attention over many decades, but what about completion damage? Before we discuss this question, we first need to define these terms. Formation damage could be considered as damage to the near-wellbore (e.g., mud solids invasion, plugging). In contrast, completion damage is damage to the lower completion (e.g., plugging of screens). The combined effect of formation and completion damage is the observed well productivity development with associated skin and productivity index. Completion damage has the potential to affect well productivity to the same degree as formation damage. However, at a basic level, there is not even a classification system for completion damage, and yet one has been available for formation damage at least 30 years, possibly longer. Within Equinor, we are trying to address this imbalance by having increased focus on completion damage. We have an ongoing project to develop the following:

A classification system—We have focused on lower completion design and damage that can occur over a well’s lifetime.

A review of testing procedures used and development of new ones where appropriate.

Use of computation fluid dynamics (CFD) more in completion damage evaluations—This approach has provided invaluable new insights. We are using CFD, for example, to visualize displacement efficiency from drilling to completion fluids. We also are incorporating data from coreflooding and completion-damage testing into a single CFD simulation that will enable us to assess what effect formation and completion damage will have on future well productivity.

Background: Bioremediation is crucial for recuperate polluted water and soil. By expanding the surface area of substrates, biosurfactants play a vital role in bioremediation. Bioremediation is crucial for recuperate polluted water and soil. By expanding the surface area of substrates, biosurfactants play a vital role in bioremediation. Biosurfactant producing microbes release certain biosurfactant compounds, which are promoted for oil spill remediation. In the present investigation, a biosurfactant producing bacterium Bacillus tequilensis was isolated from Chilika lake, Odisha, India (latitude and longitude: 19.8450 N 85.4788 E). Whole Genome Sequencing (WGS) of Bacillus tequilensis was carried out using Illumina NextSeq 500.Results: The whole genome sequence is 4.47 MB consisting of 4,478,749 base pairs forming a circular chromosome with 528 scaffolds, 4492 protein-encoding genes(ORFs), 81 tRNA genes, and 114 ribosomal RNA transcription units. The total number of raw reads was 4209415, and processed reads were 4058238 with predicted genes of 4492. The whole-genome obtained from the present investigation was used for genome annotation, variant calling, variant annotation and comparative genome analysis with other existing Bacillus species. In this study, a pathway was constructed which describe the biosurfactant metabolism of Bacillus tequilensis.

The novel coronavirus disease (COVID-19) emerged in late 2019 has shown that research done with open data could bethe cornerstone for overcoming the need for collaborative, optimized and urgent analysis. Although several articles have beenpublished, identification of variables that can have correlation with positive PCR results is still a challenge. In this paper weshow a concrete example of open data analysis from 910 patients attended in the hospital undergoing SARS-CoV-2 RT-PCR inthree private institutions in S ̃ao Paulo, Brazil. We performed an exploratory analysis using principal component analysis, featureselection and predictive algorithms to test for associations between a number of laboratory test abnormalities and the SARS-CoV-2 RT-PCR result. More concretely, we found a set of 18 variables that showed some association with a positive PCR result.Among these variables elevated lactic dehydrogenase (LDH) and d-dimer were the most correlated with a positive RT-PCR. Wedeveloped a classifier that achieved 76% mean accuracy, 77% mean precision and 92% mean sensitivity to identify individualswith COVID-19

In this study, silver oxide nanoparticles (Ag2O-NPs) were synthesized from silver nitrate using green amaranth leaf extract as reducing agent. The degradation of caffeine and inactivation of Escherichia coli by Ag2O-NPs was studied under compact fluorescent lamp illumination irradiation. Apart from that, the antibacterial and antioxidant activities of Ag2O-NPs were also examined. Synthesized Ag2O-NPs were shaped like monodispersed husk, and cubic structured with surface area and average particle size was detected to be 100.21 (m2/g) and 81 nm respectively. Antioxidant efficacy of the Ag2O-NPs was evaluated using 1, 1-diphenyl-2-picrylhydrazyl and 91% inhibition was achieved with 100 µg Ag2O-NPs. Bacteriocidic propensity of Ag2O-NPs was examined against the S. aureus and P. aeruginosa by disc diffusion, minimum inhibitory concentration (MIC), Live and dead assay. It was observed that the NPs have higher bactericidal effect on Gram-negative as compared to Gram-positive bacteria. Up to 96% photocatalytic inactivation of E. coli was achieved using 30 µg/mL of NPs, Photocatalytic degradation of caffeine (50 ppm initial concentration) was observed to be 99% at pH 9 in 15 h using 50 mg/L of Ag2O NPs. These results indicate that Ag2O NPs can be employed in environmental applications like harmful bacteria inactivation and organic pollutants degradation.

Published: April 2021

The study examines the effectiveness of the monetary policy transmission mechanism in Nigeria by estimating a sticky-price DSGE model using the Bayesian estimation approach. This study is important given the implicit inflation targeting framework employed in the implementation of monetary policy in the country. The study employs quarterly data from 2000:1 to 2019:4 to estimate the two main categories of monetary policy frameworks, monetary aggregate and implicit inflation targeting, respectively. Data are sourced from World Development Indicator (online version). Empirical results show that the monetary policy transmission channels are effective in transmitting policy impulses to the economy within this regime. However, the monetary aggregate framework that is made explicit dampens the achievement of this framework. The study, therefore, concludes that inflation targeting should be made explicit in the country in other to reap the benefits embedded in the framework.

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. It typically affects the lungs (pulmonary tube) but, can affect other parts of the body as well (extra pulmonary tube). The study was aimed to investigate the determinants of time to drop out of treatment for TB patients. Secondary data was used from 375 TB patients of the selected health stations and hospitals at Buno-Bedele and Illu Aba Bora Zones. The response variable for this study was the survival time (Time to dropout the treatment among TB patients) measured in days and the covariates were gender of the patient, marital status, HIV co-infection, Phase of TB treatment, TB type, TB category, Previous TB history, HIV Co infection, Anemia and Physical inactivity. Descriptive statistics, Kaplan-Meier Estimation method, Semi-parametric survival models and parametric survival models were used for the analysis of time to TB treatment dropout dataset. From 375 patients who started TB treatments about 24.8% dropout and 75.2% censored at the end of the study and the median survival time of TB patients were 199 days. The Log-rank results showed that marital status, HIV co infection, Diabetic mellitus, Cancer and Anemia cases had significant difference between the survival experience at 5% level of significance, whose different levels have an impact in the survival time of TB patients; whereas Sex, Phase of TB treatment, TB type, TB category, previous TB status, co-morbidity, and physical inactive had not significant difference between the survival experience at 5% level of significance. Finally, the result of Cox-proportion hazard model showed that, age, HIV co-infection and Anemia had a significant effect on tuberculosis patients during the study period.

Published: April 2021

Purpose: Omentin-1 plays an important role in regulating insulin sensitivity outside pregnancy. We aimed to evaluate whether circulating maternal omentin-1 concentrations are associated with fasting serum glucose, insulin, HOMA-IR and maternal obesity as measured by body mass index (BMI) and subcutaneous and intra-abdominal fat thickness measurements in normoglycemic pregnant participants.Methods: Omentin-1 was measured in a sub-cohort of 50 participants in the Omega study. We examined the cross-sectional association between omentin-1 and fasting glucose, insulin, HOMA-IR, BMI and subcutaneous and intra-abdominal fat thickness. We performed a subgroup analysis by BMI category.Results: Omentin-1 was negatively correlated with HOMA-IR and insulin and inversely associated with serum glucose concentration in the fully adjusted model ( −47%; slope per tertile increase in concentration −0.19; P-trend 0.01). This association was significant in non-overweight/obese (<25 kg/m2) but not among overweight/obese (≥25 kg/ m2) participants. The association with serum insulin in the fully adjusted model was not significant. Conclusion: Circulating omentin-1 concentrations are inversely associated with serum glucose concentrations. Although the significance of these findings remains to be elucidated, it may indicate a mechanism for the development of insulin resistance and gestational diabetes. Follow-up studies with larger sample sizes are warranted.

With the rapid development of urbanization, large numbers of cone-shaped or tower-shaped isolated peaks and peak forest were surrounded by a human-dominated urban matrix in the process of urban expansion in Karst areas,forming urban remnant hills (URHs), which are important resources of indigenous plant diversity from the urban environment in these areas.Although the studies on urban plant diversity have been extensive, studies on the plant diversity of the remnant habitats, especially those based on URHs,is very weak.In this study, a total of 143 sample plots were set up on 15 hills based on the combination of slope direction and elevation.Alpha diversity was calculated at four levels, i.e.,tree,shrub,herb and whole plant.Four urban matrix characteristic indices,namely,percent total impervious surface area (PTIA),land use,vegetation coverage (VC) and fragmentation indices (FIs),were measured for each hill.Twenty scales, ranging from 100 m to 2000 m and with increasing steps of 100 m,were used as spatial scales.Pearson correlation analysis and linear regression model were used to study the relationship between URHs plant diversity indices and urban matrix indices.The results showed the following:(1)There was a significant positive correlation between the overall plant diversity of URHs of different sizes and PTIA in the surrounding urban matrix within 1600 m.The overall plant diversity of URHs of different scales was significantly correlated with single or multiple Land-use types.There was no significant correlation between VC,FI and URHs overall plant diversity.(2)There was a significant linear relationship between plant diversity at all levels of different scales URHs and the four urban matrix indices.In addition to the small URHs herbaceous diversity,plant diversity at all levels of URHs was jointly affected by double or multiple factors at the 1800 m spatial scale. plant diversity of URHs of different scales in hilly Karst cities are extremely complex under the combined action of multiple factors and multiple scales.

Two soils contaminated with potentially toxic metals (PTMs) contrasting in pH and mineralogy were remediated with CaEDTA, and changes in soil organic matter (SOM) composition were investigated. Previous studies showed no significant loss of SOM from CaEDTA-treated soils, but the results of our study reflected significant decreases (from 46 to 49%) in the free fraction of humic acids (HAs). Remediation affected the composition of the free HA fraction via disturbance of intermolecular bonds - an increase in phenolic and aromatic groups with a simultaneous decrease in carbohydrates - which was confirmed by FTIR spectroscopy in both soils. Because non-radical molecules such as carbohydrates were selectively removed, the concentration of free radicals in the free HA fraction increased in acidic soil. The bound fraction of HAs and fulvic acids (FAs) in SOM, which are important due to their stability and the permanent effects they have on the soil’s physical properties, remained unchanged in both remediated soils. The effect of soil recultivation was observed only in the EEM fluorescence spectra of HAs. In terms of SOM, CaEDTA soil washing can be considered moderately conservative, however, the restoration of free humic fractions is likely to be a long-term process.

Generalized likelihood uncertainty estimate (GLUE) approach are heavily affected by the choices of cut-off thresholds and likelihood measures. This work attempts to study the potential mechanisms behind the impacts induced by cut-off thresholds and likelihood measures on confidence interval obtained by GLUE. A theoretical analysis on typical likelihood measures reveals that the error model of likelihood measure has essential impacts on the sampling processes of GLUE. Likelihood measures based on a same error model are mathematically transferrable, leading to an identical population of acceptable parameter sets. A case study is conducted by applying GLUE to uncertainty analysis on daily flows simulated by HBV model for the source region of the Yellow River basin. Seven interval indicators are adopted to describe the geometric features of confidence intervals, which are integrated into a comprehensive score for an overall assessment by multiple attribute decision making (MADM) framework. Results indicate that 1) With an increase of cut-off threshold, confidence interval widens in low-level flow sections, moves upward in recession phases of medium-level flow sections whereas narrows in high-level flow sections. Trade-off mechanism amongst widening, moving and narrowing trends is a potential reason behind the variations of interval indicators with cut-off threshold. 2) Much higher similarities in confidence intervals can be detected for likelihood measures based on a same error model than those based on different error models; 3) increasing cut-off threshold highlights the impacts induced by the error models of likelihood measures, whereas weakens the impacts induced by the formulas of likelihood measures.
