Authors: Ghouat M , Haddout A. , Benhadou M.
Published: March 2021

Industrial companies looking for permanent performance are facing challenges of reducing production costs, reducing customer delivery delays and improving their quality products, this lead them to improve their responsiveness and flexibility to meet the varying needs of customers. To cope with these constraints, several industrial companies have adopted the Lean Manufacturing (LM)  concept, based on the Toyota production system, to reduce wastage according to a methodical and structured approach that has given this proof for several years, this approach currently finds its limits, since it is based on static data, while a dynamic approach, with real-time data on customer needs and production performance, will readjust the levers of Lean Manufacturing to improve its efficiency. This paper has been aimed to show that the concept Industry 4.0 incarnates the lean Manufacturing approach by feeding it by real-time data and a real-time analysis of Big Data in a Cyber Physical Production System (CPPS), in order to improve decision-making and readjust in real time the levers of the Lean Manufacturing approach

“O FURO A QUALQUER PREÇO”: PRÁTICAS DISCURSIVAS DE PODER E RESISTÊNCIA ANTE ATITUDES MACHISTAS EM CENÁRIO DE DEMOCRACIA FRÁGIL
Authors: Silva Marluce Pereira da , Rosado Cid Augusto da Escóssia
Published: March 2021

RESUMO A jornalista Patrícia Campos Mello, da Folha de S.Paulo, foi envolvida em uma polêmica a partir do depoimento de Hans River do Rio Nascimento à Comissão Parlamentar Mista de Inquérito (CPMI) das Fake News, no Congresso Nacional brasileiro. Ex-funcionário da Yacows, empresa de marketing digital que atuou na campanha de Jair Messias Bolsonaro à presidência da República, o depoente acusou a repórter de lhe oferecer sexo em troca de matéria. O presidente, suposto alvo da investigação jornalística conduzida por Patrícia, a serviço da Folha, apropriou-se da fala de River para declarar que “Ela queria dar o furo a qualquer preço contra mim”. Tais afirmações alimentaram manifestações machistas de cunho sexual contra a jornalista, nas redes sociais, levando-a a reagir com a publicação do artigo intitulado “Depoimento: No Brasil, ser mulher nos transforma em alvo de ataques”. Com base nesse episódio, objetiva-se, em primeiro plano, abordar a evolução do conceito de democracia e de direitos fundamentais, debatendo como práticas discursivas que expressam sentidos de violência em função do gênero indiciam sintomas de fragilidade democrática. De maneira específica, com amparo em metodologia de análise do discurso de inspiração foucaultiana, investigam-se a formação sócio-histórica dos enunciados, as verdades valorizadas nas produções discursivas dos contendores e as relações de poder e resistência estabelecidas entre eles. Os resultados apontam para a compreensão de que, nas democracias frágeis, discursividades centradas no gênero emergem efeitos de sentidos reveladores não só de estratégias de poder e dominação, mas também de táticas de resistência e transformação.

Authors: Watanabe Giselle
Published: March 2021

Um olhar mais crítico sobre os acontecimentos que permeiam nossa realidade requer formação escolar científica pautada por uma perspectiva mais complexa e reflexiva. Isso se dá especialmente ao considerar as Dimensões da complexidade nos contextos específicos da educação, do processo ensino-aprendizagem e da epistemologia, incorporadas em propostas de aulas de ciências mais abertas e dinâmicas. Considerando esses pressupostos, esse artigo identifica e analisa aspectos da complexidade (i) em uma proposta de aulas de Física sobre as emergências climáticas; e (ii) nas impressões sobre esta proposta de docentes da escola básica. Tomam-se elementos da Análise de Conteúdo para organização e interpretação dos dados. Dos resultados, destacam-se que os aspectos da complexidade quando incorporados em propostas de aulas tem potencialidade de aproximar o ensino das ciências das realidades dos sujeitos, em especial, porque dá abertura para reflexões mais participativas e criativas, embasadas em distintas esferas do conhecimento, como a científica, cotidiana, cultural, política e econômica. Nota-se também que as intencionalidades projetadas pelos pesquisadores são relativamente frágeis visto que grande parte dos conhecimentos conceituais é suprimida na análise docente acerca das aprendizagens de seus estudantes.Palavras-chave: Ensino de Física, Ambiente, Risco, Dimensões da complexidade.
An analysis of chronic kidney disease as a prognostic factor in pediatric cases of COVID-19

Published: March 2021

Abstract Advanced age is a risk factor for severe infection by acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Children, however, often present with milder manifestations of Coronavirus Disease 2019 (COVID-19). Associations have been found between COVID-19 and multisystem inflammatory syndrome in children (MIS-C). Patients with the latter condition present more severe involvement. Adults with comorbidities such as chronic kidney disease (CKD) are more severely affected. This narrative review aimed to look into whether CKD contributed to more severe involvement in pediatric patients with COVID-19. The studies included in this review did not report severe cases or deaths, and indicated that pediatric patients with CKD and previously healthy children recovered quickly from infection. However, some patients with MIS-C required hospitalization in intensive care units and a few died, although it was not possible to correlate MIS-C and CKD. Conversely, adults with CKD reportedly had increased risk of severe infection by SARS-CoV-2 and higher death rates. The discrepancies seen between age groups may be due to immune system and renin-angiotensin system differences, with more pronounced expression of ACE2 in children. Immunosuppressant therapy has not been related with positive or negative effects in individuals with COVID-19, although current recommendations establish decreases in the dosage of some medications. To sum up with, CKD was not associated with more severe involvement in children diagnosed with COVID-19. Studies enrolling larger populations are still required.

Authors: Shchepilova Galina , Zhukov Dmitry
Published: March 2021

The article deals with the influence of the landmark event - the Crimea and Sevastopols reunification with Russia - on the peninsulas information space, whose functional importance is crucial for interaction with the audience. The object of the research is television as part of the information space that has always had the biggest effect on the population as compared to the other mass media, regardless of the statesmanship (Soviet, Ukrainian, or Russian). The authors do a detailed study of the current period of television development. They point out that, in order to draw a coherent picture of the Crimeas television broadcasting system, it is necessary to analyze its multiple aspects, namely, finance, content, organizational and legal sphere, technologies and audience. However, the authors focus on the structural transformation of television in the Crimea and Sevastopol. The aim is to determine the place of the peninsulas current television broadcasting system in Russian media environment, and to outline its problem spots. The empirical base of the research, which provides for better understanding of the current state of the television industry in the Crimea, is a historical retrospective review of its establishment based on public information sources and expert evidence. The key research method is insider view. The theoretical base includes approaches to studying media systems, as well as the concept of the frontier.

Multiple SARS-CoV-2 variants have evolved that increase the transmissibility of the virus and/or cause its escape from immune response. Whole genome sequencing remains the gold standard and is implemented into the national surveillance programs worldwide to detect these novel variants of concern. However, this technique cannot immediately be scaled up when a fast action is needed to limit the spread of SARS-CoV-2 variants every time a new outbreak occurs, as this can be laborious and time-consuming. Two key mutations with multiple reassurance in the SARS-CoV-2 spike glycoprotein have been identified to have a distinct signature enabling to detect five SARS-CoV-2 variants (B1.351, B1.1.7, P1 and N439K/Y453F variants). Three of them are SARS-CoV-2 variants of major concern worldwide. We developed a specific multiplexed RT-qPCR to detect these key mutations, the H69/V70deletion and the N501Y mutation and increased the sensitivity of the PCR by using LNA probes targeting the N501Y mutation carrying a single amino acid exchange. Additionally, we can exclude target failure and secure SARS-CoV-2 detection by a primer/probe pair detecting the Wt sequence (SARS-CoV-2; Wuhan lineage) at aa position 501. Our multiplexed RT-qPCR assay offers an alternative strategy for SARS-CoV-2 variant surveillance detecting five SARS-CoV-2 variants, which can build up on to detect new emerging SARS-CoV-2 variants.

Development of An Integrated Surface and Sub-Surface Simulation Model in A Single Simulation Platform
Authors: Zainal S A , Daud W R , Rosli M I , Harun S , Adi Putra Zulfan , Bilad M R
Published: March 2021

An integrated model between surface and sub-surface is typically done by interconnecting many process modelling platforms. PROSPER and GAP are the common steady state modelling platforms for sub-surface while VMGSim and HYSYS are typical steady state surface modelling platforms. A major issue of using multiple simulation platforms is the compatibility of thermodynamic physical properties calculations among the platforms. This situation makes the simulations difficult to converge to a consistent thermo physical properties values. This is due to different interaction parameters applied in each platform that impact flashing and the physical property values even though the same property package such as Peng Robinson is used. To overcome this convergence problem, a single simulation platform within iCON (PETRONAS’s standard process simulation software, co-developed with VMG-Schlumberger) has been developed. This allows the use of one thermodynamic package across the integrated model. PROSPER sub-surface pressure-flow relationship results were automatically correlated and connected to surface models within the iCON environment. This integrated model was validated with data from operations and yielded about 1.23% average error tolerance. Based on this validated model, an optimization envelope can be developed with all possible well lineup configurations. This envelope covers set points for the operations where CAPEX free optimization can readily be applied.

Indonesia faces decreasing in its number during period of 2018-2019 according to SINTA (Indonesian scientific indexing) database. This situation is alarming amid country’s effort to improve its research and development from which the scientific publication has been used as a measure. This article presents a dataset of bibliometric from all Indonesian institutions (424 institutions as of January 2020) indexed by Scopus database. We collected data on documents per year and document type. Different from other datasets, this article presents longitudinal data from 2014-2019, in which during this period dramatic change occurs from steep rise, exponential, and degradation during 2018-2019. We analyzed publication number from leading institutions at different points in time and compared document types (i.e., number of journal article and conference paper, in which both types are the driving force of Indonesia’s growing scientific publication number). Since this dataset covers all country’s institutions, it is potential for reuse by policy makers in research and development, researchers from each institution, as well as other stakeholders.

Authors: Machmud Amir , Minghat Asnul Dahar Bin
Published: March 2021

This study aims to analyze the impact of the COVID-19 pandemic on changes in handsanitizer prices in Indonesia. This study is motivated by the increasing demand for handsanitizers which has had an impact on price ratings. The method used is an explanatory survey with an exponential form approach for the demand function and Linear Cobweb Form for the supply function. The structure of the hand sanitizer market is assumed to be a perfectly competitive market. The results of the study indicate that despite changes in prices, the numerical analysis shows that prices are stable. The entry and exit of companies in the market does not affect price stability. This finding implies that after the pandemic the prices of handsanitizers will return to normal, so producers and consumers must remain rational.

CDIO Initiative: A Guarantee for Successful Accreditation of Engineering Programmes
Authors: Al-Obaidi Abdulkareem Sh. Mahdi
Published: March 2021

The accreditation bodies and engineering councils set a number of qualifying requirements and accreditation criteria to ensure the quality of engineering graduates and programmes. One of these requirements is the engineering curriculum. Some institutions using the traditional engineering curriculum often face difficulties and burden to meet the accreditation minimum academic requirements as their curriculum lacks the innovation and the integration of graduate attributes such as personal, interpersonal, teamwork, entrepreneurship, development of life skills and emotional wellbeing, among many. This eventually leads to deferred or even declined accreditation. To overcome these difficulties, the CDIO initiative is an ideal tool for successful accreditation. The CDIO standards, syllabus, engineering curriculum, and learning outcomes are not only meeting what accreditation bodies require, but they offer innovative curriculum more on high-level cognitive skills set in the context of the product-system lifecycle; Conceiving-Designing-Operating-Implementing metaphases. This paper shares a successful engineering education experience of the School of Engineering/Taylor’s University and how the CDIO initiative contributed not only to a successful accreditation but also to have a new innovative engineering curriculum. The adopted new curriculum is innovative, hands-on and project-based in order to achieve integrated learning where acquiring discipline-specific knowledge and CDIO skills take place simultaneously

Published: March 2021

Py-GC/MS analysis of six different species of fast growing Macaranga wood has been studied. Flash pyrolysis was conducted at different temperatures (250-850 oC) under a flow of helium followed by GC/MS analysis of the products. The total pyrolysis yields of the six different species of Macaranga were mostly between 40 and 90% within the range of pyrolysis temperature applied.  Pyrolysis of the woody biomass produced compounds which are mostly derived from thermal degradation or volatilization of lignin and cellulose/hemicellulose, the original major constituents of the biomass. The Py-GC/MS technique indicated that M. gigantea was the most potential species for biofuel production and the optimum pyrolysis temperature to produce high yields of bio-oil was 450 oC.

Ion-adsorption rare earth ores of China
Authors: Bugrieva E. P. , Tarkhanov A. V. , Trubakov Yu. M.
Published: March 2021

Geology and geochemistry of China’s ion-adsorption rare earth ores are discussed. The structure and material constitution of Lognan, Huashan, Guposhan and Heling deposits are compared. The weathered layer structure, as well as the distribution, differentiation and occurrence forms of rare earth elements (REE) in the weathered layer are described. The prospecting indicators and criteria of readily dissociated adsorbed REE ore are identified to find this type ores in the territory of Russia. The weathered layer enclosing ion-adsorption rare earth ore features specific differentiation of REE. General composition of such ores is governed by the composition of the primary rare earth mineralization in mother granites. If granites contain much yttrium and heavy lanthanides, then ion-adsorption rare earth ore contain also much yttrium and heavy lanthanides. Regarding differentiation of REE, yttrium and heavy lanthanides mainly concentrate in the middle, most clayey part of the weathered layer, while cerium accumulates in subsurface lateritic soil. The prime feature of ion-adsorption rare earth ore is the prevalence of readily dissociated REE, which can reach a quantity of 80% and more but not less than a half. The rest REE concentrate in relict rock-forming minerals and accessories. The quantitative estimation of adsorption form of REE is necessary for the geological and economic appraisal of a deposit. It is assumed that the quantity of readily soluble REE should be not less than 0.05–50% of the total content. Russia has many regions with such geotectonic environment. It is required to explore ion-adsorption rare earth ore occurrences in these regions.
Study of the relationship between the zeta potential and floatability of cassiterite fine fractions
Authors: Gazaleeva G. I. , Nazarenko L. N. , Dmitrieva E. G.
Published: March 2021

This article is a continuation of the authors’ research on improving the flotation process for fine tin products using zeta potential measurements on particle surfaces. The aim of the research is to establish the possibility of using certain reagents to intensify the flotation of fine cassiterite particles and to identify the mechanism behind the effect produced by the reagents on the surface of slurry particles in cassiterite flotation using zeta potential measurements. The results of experiments to select the best collector are presented, with salicylhydroxamic acid identified as the best option. Sodium hexametaphosphate pretreatment of a flotation slurry consisting of fine particles enables a more efficient cassiterite flotation, which is explained by the negative value of the z-potential for the particle surface. The use of sodium hexametaphosphate improves the yield by up to 3 %, with the mass fraction of tin growing from 1.2 to 1.75 %, and the recovery improving from 40 to 75 %. The results of z-potential measurements for the particle surface in the process of flotation indicate that its positive values are not always required and that the combined action of oxalic and sulfuric acids with salicylhydroxamic acid at a z-potential of –0.7 mV renders the maximum tin grade of 2.22 % in the froth flotation product. Gravity treatment of the flotation concentrate on concentration tables allows obtaining conditioned concentrates with the mass fractions of tin of 23.4 and 30.6 %.

The environmental impact of non-ferrous metallurgy sites is a well-studied and thoroughly described phenomenon characterizing industrially developed areas. New techniques are being developed and adopted to help reduce the amount of metal compounds released in the environment by the industry. The so-called fugitive sources of pollution, which include polluted areas surrounding industrial sites, have been a recent focus of attention. This paper considers the possibility to use vermiculite-sungulite materials obtained by concentration of tailings produced by a phlogopite mine in Kovdor (Murmansk Region) as a sorption material to be used for removing heavy metals from contaminated ponds of the Monchegorsk Industrial Area in the Murmansk Region. A series of experiments has been conducted during which sampled water was treated with vermiculite-sungulite materials. This sorption treatment technique was established to be efficient. Some resultant solutions have residual concentrations of metals <10 mcg/L, with the purification efficiency exceeding 85%. The factor determining the process of removing nickel and copper from contaminated water includes pH, which is reached as a result of water interacting with the above materials. In the equilibrium state, provided the рН level in the system is maintained above 8.5, vermiculite-sungulite materials can keep metals sorbed thus preventing their migration from the sorption layer. The findings show that due to the use of finely dispersed materials the concentrations of copper and nickel can be lowered from 10 mg/L to a few micrograms.

Published: March 2021

Relevance.The study of the timing and duration of individual phases of the development of strawberry cultivars of different ecological and geographical origin in these climatic conditions is of great practical importance. The purpose of the study was the determination of the timing of the main phenophases of introduced strawberry cultivars in the Orel region, the compliance of the phenorhythms of the studied cultivars with climatic conditions, as well as the ranking of the cultivars by the terms of flowering and maturation.

Methods and materials.The article presents the results of phenological observations for the period 2016-2019. 34 strawberry cultivars of domestic and foreign selection were studied. The research was carried out at the VNIISPK site of primary variety study.

Results. Based on long - term observations, on the time of entry into the flowering and fruiting phase, the cultivars were ranked into early, medium and late-maturing. The influence of effective temperatures on the onset of phenophases was analyzed. The sum of effective temperatures necessary for the beginning of flowering of strawberry cultivars of different maturation periods in the conditions of the Orel region was determined. For the onset of strawberry flowering, it takes from126.68 to 260.37°effective temperatures. Early cultivars need the sum of effective temperatures of 126.68-197.55°, cultivars of middle maturation need 146.31-225.44°, late cultivars - 159.93-260.37 depending on the year of study. Fruiting occurs at the sum of effective temperatures in early cultivars from 351.73°C to 465.43°C, in middle-maturing cultivars from 390.96 to 535.44°C, in late-maturing cultivars from 450°C to 649°C.

Published: March 2021

Relevance.The presence of valuable biologically active substances, carbohydrates, organic acids and others in the eggplant fruits makes the culture one of the vegetables with the highest antioxidant activity. The VIR collection of eggplant includes 830 accessions from 70 countries of the world. The study of new acquisitions in the VIR collection presupposes a comprehensive assessment of the received material according to morphological, biological and economically valuable characteristics. The main objective of the study was to assess the variability of the biochemical parameters of egg-plant fruits in technical ripeness; as well as determination of the best accessions by the chemical composition of fruits and the content of biologically active substances.

Materials and methods.The study of 19 accessions of eggplant accessions was carried out in 2020 in a winter greenhouse in Pushkin and Pavlovsk Laboratories of VIR (St. Petersburg). The morphological description of the accessions and the assessment for biological and economically valuable traits were carried out in accordance with the methodological guidelines and the VIR classifier. Biochemical analysis was carried out in the Department of Biochemistry and Molecular Biology of VIR in the phase of technical ripeness of fruits in terms of: dry matter content, sugars, total acidity, ascorbic acid, pigments and anthocyanins.

Results.As a result of this study, the amplitude of variability in the content of dry matter (6.44- 8.68%), sugars (1.78-3.72%), ascorbic acid (5.92-21.08 mg/100 g), titrated acidity (0.10-0.31%), chlorophylls (0.52-15.13 mg/100 g), carotenoids (1.19-6.99 mg/100 g), β-carotene (0.11-0.52 mg/100 g) and anthocyanins (12.94-1031.40 mg/100 g) in eggplant fruits. Accessions with a high content of biologically active substances in fruits in technical ripeness were identified: Russian hybrids Bourgeois F1, Azhur F1; local accessions from Armenia: k-3156, k-3159, k-3161.

Relevance. Photosynthetic seedlings, as a model object, are interesting both in the study of nutritional value and the species response of a plant organism to the cultivation.

Material and methods. The study was carried out on the basis of the laboratory analytical department of the FSBSI FSVC. The material of the research was sprouts of Brassica chinensis L., cv. Vesnyanka; Brassica oleraceae L. var. italica Plenck, cv. Tonus; Brassica oleracea L. convar. acephala DC., cv. Malinovka; Brassica oleracea var. gongylodes L., hybrid F1 Sonata and cv. Venskaya Belaya 1350; Brassica oleracea L. convar. capitata (L.) Alef. var. capitata L. f. rubra (L.) Thell., cv. Gako 741. The seeds of the 2018 harvest were germinated in filter paper cassettes using distilled water. The cassettes with seeds were placed in a thermostat under constant illumination and a temperature of 25°C. They have been germinated for 8 days, after which a biochemical analysis of the samples was carried out.

Results. It was found out that the total content of water-soluble antioxidants in the studied of cabbage crops was in the range of concentrations from 3.58-4.57 mg-eq HA/g (wet weight). According to this indicator of 8-day-old seedlings, red cabbage variety Gako 741 was distinguished by the maximum values. The total content of antioxidants in the alcoholic extract ranged from 21.24 to 28.23 mg-eq HA/g (dry weight). The content of polyphenols – in the concentration range of 16.39-24.94 mg-eq of HA/g (dry weight). As a result of the research, direct correlations of the studied characteristics were revealed. A high correlation was shown between the content of water-soluble antioxidants and dry matter (r=0.72...0.98) and between the content of carotenoids and chlorophylls (r=0.98...0. 99).
