Water is the basic value of human life. However, the shortage of drinking water in the world is increasing and this global negative trend creates a strategic humanity threat. Because of this, the importance, economics, and water supply strategy are becoming more relevant and have become national security important factor. The authors analyze the main strategic tools for the drinking water shortage compensating in a number of regions and countries of the world and show that one of them is the drinking water bottling. Unlike the majority of foreign and domestic studies devoted to commercial aspects of the production and sale of bottled drinking water, the authors of this study consider these aspects mainly from the point of view of public and state (budget) efficiency. The article formulates the strategic possibility, feasibility and forms of fresh water in Russia commercialization – a country with one of the highest levels of availability of this resource. The authors consider the main priorities and formulate the main principles of strategizing the development of the Russian bottled drinking water industry. The authors also show that one of the most effective tools for successful implementation of the industry development strategy is strategic marketing and branding.

Authors:   Governor of Kemerovo Oblast, Tsivilev Sergey E.
Published: June 2021

The article is devoted to the actual topic – the implementation of adopted in December 2020 the Kuzbass Region Development Strategy until 2035, aimed at improvement the citizens’ quality of life based at cardinal transformations in the region. The object of the study is the strategic socio-economic processes of Kuzbass Region; the subject of the study is the management of the Strategy implementation processes. The research is based on the methodology of Foreign Member of the Russian Academy of Sciences (Life-time), Dr. Sc. (Econ.), Professor of Political Economy V.L. Kvint, as well as on the processes of a management system for the Kuzbass Strategy implementation analysis. The Kuzbass Region Strategy has deep historical roots, based on the unique natural resources and regional industrial raw materials base, implements sound strategic priorities for a better life for the current and future generations of Kuzbass Region residents, economic development and investment attractiveness growth. The implementation of strategic priorities requires the necessary resources and sustainable strategic competitive advantages. The most important resource is the human potential that allows Kuzbass Region residents to respond to numerous strategic challenges and use the opportunities that arise in the modern world. The task of strategic management is to ensure the sufficiency and continuity of the resource supply process throughout the entire period of strategizing. One of the most important priorities of the Strategy, in this regard, is the reproduction of labor resources. Since the mainstay of the Kuzbass Region economy is traditionally the coal industry, the most important priority of the Strategy is the implementation of the regional environmental standard “Clean coal-green Kuzbass Region”. It is planned to form vanguard industrial clusters, such as hydrogen energy and coal chemistry, using coal as a raw material. The celebration of the 300th anniversary of Kuzbass Region should give an impetus to the development of the entire region, will increase its tourist potential, and the strategic brand of Kuzbass Region should become recognizable in Russia and abroad. In general, the development of the image of the region is a key task that will improve the public mood in the region and increase its attractiveness for living. In Kuzbass Region various digital projects are already being implemented, new digital platforms are being built, and in the future their role will increase. Financial support for the implementation of strategic priorities is based on the vanguard regional development institutions and the activation of securities market in Kuzbass Region.
The burden and etiology of lower respiratory tract infections in children under five years of age in Indonesia
Authors: Ciptaningtyas Vincentia Rizke , De Mast Quirijn , De Jonge Marinus Isaäk
Published: June 2021

Introduction: Lower respiratory tract infections (LRTI) are a substantial threat for children worldwide. Currently, there is a lack of knowledge about the burden and etiology of LRTI in children under five years of age in Indonesia.

Methodology: We have systematically searched the available English and Indonesian scientific literature to review and summarize data on LRTI and LRTI-associated invasive disease, and bacterial carriage in the upper respiratory tract in children under five years of age in Indonesia.

Results: Overall, data on the burden and etiology of LRTI in children under five years of age in Indonesia is very limited. The data are primarily collected in Java. Data from other parts of Indonesia, including Sumatra, Kalimantan, and Sulawesi, are scarce. The case fatality rate (CFR) of LRTI in children under five years of age in Indonesia was 0.11%. Influenza was the most commonly reported viral etiological agent of LRTI in children under five years of age in Indonesia. Klebsiella pneumoniae was the most frequently reported bacterial agent of LRTI. Streptococcus pneumoniae showed the highest carriage rates.

Conclusions: Surveillance and diagnostic studies are urgently needed and should be conducted in different parts of Indonesia to improve insight in the burden and etiology of LRTI in Indonesia. These data are pivotal to increase the effectiveness of public health strategies, including vaccination and prevention of antimicrobial resistance.

Venous thromboembolism (VTE) represents an important clinical complication of patients with SARS-CoV-2 infection, and high plasma D-dimer levels could suggest a higher risk of hypercoagulability. We aimed to analyse if laboratory exams, risk assessment scores, comorbidity scores were useful in predicting the VTE in SARS-CoV-2 patients admitted in internal medicine (IM). We evaluated 49 older adults with suspected VTE analysing history and blood chemistry, besides we calculated the Padua Prediction Score, the modified early warning scoring (MEWS) and the modified Elixhauser index (mEI). All patients underwent venous color-doppler ultrasounds of the lower limbs. Out of the 49 patients enrolled (mean age 79.3±14 years), 10 (20.4%) had deep vein thrombosis (DVT), and they were more frequently female (80% vs 20%, p = 0.04). We could not find any association with the Padua Prediction Score, the MEWS, and the mEI. D-dimer plasma levels were also not associated with DVT. In elderly people hospitalized with SARS-CoV-2 infection hospitalized in IM, our data, although limited by the sample size, suggest that prediction and diagnosis of VTE is difficult, due to lack of precise biomarkers and scores.

Measures for consumer protection against food adulteration and misleading labeling are integrated into EU legislation, including methods for detection of misleading practices. Verification of meat content is available for marine products but not for freshwater fish because of the lack of standard nitrogen factors. The aim of this study was to establish nitrogen factors for European pike-perch Sander lucioperca (Linnaeus, 1758), northern pike Esox lucius Linnaeus, 1758, and sheatfish Silurus glanis Linnaeus, 1758. The study involved analysis of 808 fillet samples obtained in spring (March–April) and autumn (October–November) harvest seasons, 2018–2019, from seven Czech Republic fish rearing facilities. Samples with and without skin were analyzed for nitrogen content, dry matter, protein, ash, and fat according to established ISO methods. The recommended nitrogen factor for European pike-perch with the skin is 3.28 ± 0.09 and without the skin is 3.21 ± 0.09; for northern pike with the skin is 3.18 ± 0.09 and without skin is 3.15 ± 0.09; and for sheatfish with skin is 2.73 ± 0.13 and without skin is 2.75 ± 0.12. The established nitrogen factors will enable analysis of meat content to ensure that consumers are purchasing correctly described and labeled fish products.
Identifying SOX2-OT transcript that is responsible for regulating SOX2 in cancer cells and embryonic stem cells
Authors: Dong Dao-Yin , Li Pu-Yu
Published: June 2021

SOX2 overlapping transcript (SOX2-OT) is an evolutionarily conserved long non-coding RNA (lncRNA) whose intronic region contains the transcript of pluripotency gene SRY-box transcription factor 2 (SOX2). It has been suggested that SOX2-OT can regulate its overlapping gene, SOX2. Studies demonstrated that elevated SOX2-OT promotes SOX2 expression in cancer cells, whereas levels of SOX2-OT are inversely correlated with levels of SOX2 in embryonic stem cells. It is not clear why there is a tremendous discrepancy in the regulation of SOX2 by SOX2-OT in cancer cells and embryonic stem cells. Due to the diversified transcription of the SOX2-OT gene, we hypothesize that differential expression of transcripts of the SOX2-OT gene in cancer cells and embryonic stem cells may contribute to the divergence in the regulatory relationship of SOX2-OT and SOX2. A CRISPR screening platform can be leveraged to systemic evaluate which transcript of the SOX2-OT gene may be responsible for upregulation or downregulation of SOX2 in cancer cells and embryonic stem cells, respectively.
The complete mitochondrial genome of Pentatoma rufipes (Hemiptera, Pentatomidae) and its phylogenetic implications

Published: June 2021

Pentatoma rufipes(Linnaeus, 1758) is an important agroforestry pest widely distributed in the Palaearctic region. In this study, we sequence and annotate the complete mitochondrial genome ofP. rufipesand reconstruct the phylogenetic trees for Pentatomoidea using existing data for eight families published in the National Center for Biotechnology Information database. The mitogenome ofP. rufipesis 15,887-bp-long, comprising 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region, with an A+T content of 77.7%. The genome structure, gene order, nucleotide composition, and codon usage of the mitogenome ofP. rufipeswere consistent with those of typical Hemiptera insects. Among the protein-coding genes of Pentatomoidea, the evolutionary rate of ATP8 was the fastest, and COX1 was found to be the most conservative gene in the superfamily. Substitution saturation assessment indicated that neither transition nor transversion substitutions were saturated in the analyzed datasets. Phylogenetic analysis using the Bayesian inference method showed thatP. rufipesbelonged to Pentatomidae. The node support values based on the dataset concatenated from protein-coding and RNA genes were the highest. Our results enrich the mitochondrial genome database of Pentatomoidea and provide a reference for further studies of phylogenetic systematics.
La lecture littéraire à l’université : pour un partage de l’intime
Authors: Turin Gaspard
Published: June 2021

Cet article prend pour objet un enseignement de master donné sur plusieurs années en Faculté des lettres à l’Université de Lausanne et consacré au devenir des études littéraires dans la Cité (transmission et médiation du littéraire). Mais les observations qui s’y rattachent portent ici sur les modalités peu ou mal interrogées de la lecture littéraire dans le cadre universitaire lui-même. Il découle de ces observations la nécessité d’une approche de la lecture littéraire promouvant subjectivité, créativité et prise en compte des apports de la critique didactique, dans un cadre où ces zones d’intérêt peinent à trouver leur place. Si les études littéraires trouvent, encore aujourd’hui, leur intérêt dans la construction identitaire des sujets lecteurs qui s’y consacrent, il est plus que jamais nécessaire de donner à ces derniers l’espace nécessaire à l’expression d’une subjectivité, voire d’une intimité dans le partage des récits qui nous fondent.

Ce texte est une réponse au propos développé dans ce même dossier par Dominique Hétu, prolongement d’un dialogue initialement entamé lors d’une participation commune à l’évènement scientifique support de ce numéro. Une première partie de notre propre texte permet de revenir sur deux enjeux massifs mis en lumière par Hétu, à savoir la pluralité des lieux éducatifs et les liaisons dangereuses pouvant exister entre care et paternalisme. Une seconde partie propose un bref retour ciblé sur trois éléments que la lecture du texte de Hétu met en tension et/ou en question à divers niveaux. Sont ainsi successivement abordés le lien entre autorité et auctorialité et l’importance respective des notions d’hospitalité et d’attention, le tout dans l’optique de penser ensemble care et éducation.
The Signal Gait of the Human
Authors: Motta Marco
Published: June 2021

Cet essai rend compte de ma découverte de l’importance de Stanley Cavell. Initialement conçu comme un hommage, ce texte s’avère être plutôt une méditation sur l’enseignement à propos de la lecture, de la lecture de l’autre, et de la lecture de soi par l’autre, que nous pourrions recevoir de Cavell. Il est simultanément un examen de l’idée que l’écriture est un mode de lecture, et la lecture un mode d’écriture. Il se trouve que la façon de penser de Cavell m’a été révélée durant mon terrain de recherche anthropologique à Zanzibar sur le compagnonnage entre les humains et les esprits. C’est pourquoi je retrace ici les contingences de cette révélation, et relate la manière dont la pensée de Cavell est intimement liée aux notions de rythme, de doute, de silence, de pauvreté, et de beauté.

Il exploite essentiellement l’onomastique zoologique présente dans Trésor des contes vietnamiens (Nguyen Dong Chi), recueil de contes folkloriques souvent anciens, qui constitue le corpus d’un travail de thèse en cours. Il s’agit d’une analyse linguistique de la terminologie zoonymique vietnamienne qui présente les deux caractéristiques suivantes : i) un riche éventail de zoonymes, composés principalement de noms monosyllabiques, mais aussi de locutions complexes (polysyllabiques) ; ii) l’existence de termes génériques larges, antéposés au zoonyme, qui construisent des classes linguistiques.
La création d’entreprise, remède aux maux du travail salarié ?
Authors: Landour Julie
Published: June 2021

Apparu en France dans les années 2010, le phénomène des Mompreneurs (pour « mamans entrepreneures ») repose sur la triple promesse d’une conciliation de la vie professionnelle et familiale, d’une souplesse plus grande dans l’aménagement des temps du travail, d’une indépendance nouvelle capable de donner ou redonner du sens à un travail salarié souvent vécu dans la souffrance. L’article, à partir d’une série d’entretiens avec des « mompreneurs », fait le point sur le passage des attentes à la réalité : qu’en est-il de la conciliation entre vie familiale et professionnelle ? L’indépendance à l’égard d’un patron ne se paie-t-elle pas de nouvelles dépendances à l’égard des client∙e∙s (qu’il faut chercher, qu’il faut satisfaire) ? Les protections liées au salariat ne se révèlent-elles pas mieux assurées que les gains d’une indépendance moins vécue que rêvée ?

Les relations économiques entre la France et le comté de Namur aux Temps modernes
Authors: Ronvaux Marc
Published: June 2021

Le petit comté de Namur, qui fait partie des Pays-Bas espagnols puis autrichiens, est du point de vue géographique étroitement imbriqué dans les souverainetés voisines de la France, mais aussi de Liège, ce qui en fait un bon champ d’observation du protectionnisme mercantiliste. Les échanges, qui traversent principalement par la Meuse et la Sambre, des frontières inextricables et changeantes, sont compliqués par la rivalité de trois pouvoirs, mais le réalisme des acteurs économiques l’emporte dans un contexte de guerres fréquentes et d’occupations. Cette proximité favorise aussi un afflux massif de numéraire étranger dans le comté, ce qui pose des problèmes où une souveraineté monétaire précaire se heurte aux exigences des acteurs économiques. Les sources, essentiellement fiscales, révèlent des importations namuroises de vin, d’ardoises, d’écorces pour la tannerie, de bois et de charbon de bois ; s’y ajoutent quelques produits de luxe. Dans l’autre sens, le comté exporte du fer, de la houille, des armes, des clous et du bétail. Finalement, sauf en ce qui concerne la tannerie, où Namur et Givet sont rivales, les rapports sont moins faits de concurrence que de complémentarité.
Un poème latin de La Boétie et ses variantes : l’épitaphe sur la mort du marquis de Beaupréau
Authors: O’Brien John
Published: June 2021

Le ms BnF Dupuy 951 contient un poème latin de La Boétie, son épitaphe sur la disparition brutale du jeune marquis de Beaupréau, poème que Montaigne devait publier en 1571. La version du ms Dupuy est recopiée de la main de Daniel Rogers (ca. 1538-91), poète et diplomate anglais, et exhibe sous sa plume d’importantes variantes textuelles dont nous montrons qu’elles témoignent de tout un courant d’activité intellectuelle œuvrant, au lendemain de sa mort, en faveur de la postérité littéraire de La Boétie.
Entre dispersion et centralité : l’invention du sujet dans les Essais
Authors: de Lajarte Philippe
Published: June 2021

Ce qui s’annonce, dans l’affirmation de Montaigne, au début du chapitre  Du repentir , qu’il est le premier auteur de son temps à se « communiquer » par son « estre universel », c’est l’invention d’un sujet d’un type nouveau. Ce sujet, ce n’est pas, quelque importante que soit la place qu’il y occupe, le moi empirique que les  Essais  s’appliquent à déchiffrer : c’est le sujet que ces derniers construisent dans et par leur discours. Sujet qui s’appréhende sous deux aspects opposés mais étroitement complémentaires : la dispersion, caractéristique du discours montaignien considéré du point de vue de ses énoncés, et la centralité, caractéristique de ce même discours en tant que procès d’énonciation.
Jean de Tournes, Sébastien Gryphe et Robert Granjon à Lyon en 1543 et après
Authors: Kemp William
Published: June 2021

Cet article est basé sur une étude des premières éditions de Jean I de Tournes, celles de l’année 1543. Les résultats sont présentés dans l’annexe de l’article. Trois conclusions se dégagent de l’étude. Première conclusion : De Tournes a employé un caractère romain plutôt petit de 9 points [R 65 mm par 20 lignes] pour toutes les éditions dont j’ai pu consulter un exemplaire. Ce caractère, le premier gravé par Robert Granjon selon le travail du regretté Hendrik Vervliet, fut initialement employé en 1542 par l’ancien patron de Jean de Tournes, Sébastien Gryphe, pour l’impression d’une série de Bibles latines en format in-16. Deuxièmement, dans la moitié de ces éditions De Tournes de 1543, il y avait aussi sur les pages de titre un caractère qui n’était pas attendu, un petit-canon romain d’environ 27 points [R 190 mm]. Selon les relevés de Vervliet, ce caractère est apparu chez De Tournes en 1547. De plus, à part une occurrence en 1544, ce caractère n’a pas été utilisé par De Tournes en 1544, 1545 et 1546. Les autres plus gros caractères employés dans les titres ont aussi été considérés. Comment interpréter ? Ce petit-canon aurait-il été une lettre de démonstration ou un caractère « spécimen » lui permettant de montrer ses talents de graveur par une lettre de prestige, qui était destinée à être employée sur les pages de titres ou dans les préliminaires ? On peut se demander si une telle conjoncture n’implique pas la présence de Granjon à Lyon en 1542 et/ou 1543. Ainsi, au début de sa carrière, Granjon a suivi la mode ou le parti pris parisien favorable aux caractères romains avant qu’il ne développe ses nouvelles italiques aux majuscules penchées, dont le premier apparaît à Paris en 1543, avec quelques lignes chez De Tournes la même année. Ses quatre italiques des années 1540 feront sa réputation en France et ailleurs, mais sans éclipser ses caractères romains.
Définir, diviser et énumérer : l’exemple des anatomies de la Renaissance
Authors: Montagne Véronique
Published: June 2021

Les dialectiques médicales de la Renaissance consacrent une part importante de leur développement à la question de la définition. Considérée comme un socle indispensable, un préalable dont l’importance est souvent mise en évidence, la définition est ainsi théorisée par Adrien L’Alemant, dans sa Dialectique en françois pour les barbiers et les chirurgiens (1553) comme par Philippe de Flesselles dans son Introductoire de chirurgie rationele (1547), eux-mêmes inspirés en cela par les travaux de Galien comme par ceux du maître de médecine Guy de Chauliac. L’approche définitionnelle fait partie du bagage du chirurgien « rationnel », quelle qu’en soit la forme exacte, formes qui sont explorées ici dans un corpus croisé de textes logiques, dialectiques et éventuellement rhétoriques, et d’anatomies de Charles Estienne, Ambroise Paré et Jacques Grévin, parues entre 1549 et 1569.

PARADIGMS OF COVID-19 AND THE CYTOKINE THERAPY APPROACHES
Authors: Idrees Muhammad , Nutini Alessandro , Sohail Ayesha
Published: June 2021

One of the complications caused by the viral agent SARS-CoV2 is atypical pneumonia that occurs classically in viral pathologies. These infection complications produce a sort of “cytokine release syndrome” that sees interleukin 6, a glycosylated protein of approximately 212 amino acids, among the leading players in the inflammatory process. IL-6 typically produces a transient inflammatory state that promotes the host’s immune defence through its pleiotropic function. There is the stimulation of a response in the acute infectious phase, hematopoiesis and the regular advent of immune reactions. The action of the anti-inflammatory cytokines, which tends to regulate the inflammatory one’s activity, is directed to the same cells that produce IL-6, which, through an inhibition mechanism, slow down or production ceases altogether. Evidently, in the case of the IL-6 storm, the action of these anti-inflammatory cytokines is insufficient, and the blockade of IL-6R receptors and through the use of monoclonal antibody-like tocilizumab has proved to be optimal to manage complications and avoid potentially fatal situations. Therefore, the purpose of this paper is to create a mathematical model that describes the action of the IL-6 cytokine in SARS-CoV2 virus infection to understand better the extent of the disease itself and the associated severe side effects. We represent the concentration of tocilizumab, soluble IL-6R, absolute neutrophils and circulating platelets using computational modeling. Tocilizumab is administered by intravenous infusions with a minimum dose of 80[Formula: see text]mg and a maximum dose of 400[Formula: see text]mg. Following tocilizumab administration, simulation results indicate that the population of absolute neutrophils and circulating platelets is decreasing. After the removal of tocilizumab concentration, both absolute neutrophils and circulating platelets return at their baselines.
Role of Negative Interest Rates for Energy Assets Pricing in Financial Markets

Published: June 2021

The world economy strives for globalization, and most energy assets are connected with each other through correspondent banks and other mutual operations. The relevance of the topic of the thesis is due to the fact that in September 2019 a number of proposals were made to introduce the practice of negative interest rates in the national banking system due to the fact that Russian energy assets are not profitable to place in foreign currency..
Investigation for the Role of Oil and Natural Gas in the BIST Sector Indexes in Turkey
Authors: Uzun Uğur , Adalı Zafer
Published: June 2021

In this chapter, the authors aim to investigate the association between the primary energy sources' prices involving oil and natural gas and sectors indices operating the Turkey stock market for the period covering 2012M1-2021M3. Regarding energy price indicators, Brent oil and natural gas real-time future prices are preferred in the models, and BIST Industrials (XUSIN), BIST Chem-Petrol Plastic (XKMYA), and BIST Electricity (XELKT) indices are used as financial performance indicators. Fourier unit root tests improved by Becker et al. and Fourier co-integration tests improved by Tsong et al. are employed to investigate the relationship between considered variables. As a result of the models, it is found that the energy prices and financial performance index do not move together in the long run; in other words, change in oil and natural gas prices seem not to have an impact on the sector indexes.
Investigation of the Foreign Direct Investment and Environmental Pollution Nexus for Developing Countries
Authors: Çelik Orkun , Korkmaz Özge , Adalı Zafer
Published: June 2021

In theory, the foreign direct investment and environmental pollution nexus is explained by three hypotheses. Firstly, pollution haven hypothesis assumes that there is a positive nexus between these variables. Secondly, pollution halo hypothesis supposes that there is negative connection between these variables. Lastly, neutrality hypothesis asserts the non-existence of the connection between these variables. In recent years, many researchers have frequently tested whether these hypotheses are valid for different countries. In this study, applying Westerlund panel cointegration test, the authors aim to explore the nexus between foreign direct investment and environmental pollution for 23 developing countries after global crisis. For this aim, they use annual data covering the period 2009-2019. According to the obtained empirical findings, the presence of the long-term nexus between foreign direct investment and environmental pollution is not detected for 23 developing countries. Accordingly, the authors can say that there is neutrality hypothesis.

Authors: Balakrishnan Baranidharan , Vinoth Kumar C. N. S.
Published: June 2021

Cardio Vascular Diseases (CVD) is the major reason for the death of the majority of the people in the world. Earlier diagnosis of disease will reduce the mortality rate. Machine learning (ML) algorithms are giving promising results in the disease diagnosis and it is now widely accepted by medical experts as their clinical decision support system. In this work, the most popular ML models are investigated and compared with one other for heart disease prediction based on various metrics. The base classifiers such as Support Vector Machine (SVM), Logistic regression, Naïve Bayes, Decision Tree, K Nearest Neighbour are used for predicting heart disease. In this paper, bagging and boosting techniques are applied over these individual classifiers to improve the performance of the system. With the Cleveland and Statlog datasets, Naive Bayes as the individual classifier gives the maximum accuracy of 85.13%and 84.81% respectively. Bagging technique improves the accuracy of the decision tree which is identified as a weak classifier by 7% and it is a significant improvement in identifying CVD.

The Sr hexaferrites with chemical formula Sr0.4La0.3Ca0.3Fe11.85-xGaxCo0.15O19 (x = 0.0 — 1.4) were manufactured by traditional ceramic method. The affect of Ga substitution on static magnetic properties and micromorphology of M-type Sr (SrM) hexaferrites have been presented in detail. In accordance with the experiment results, as Ga-substituted content x rises up from 0.0 to 1.4, all SrM hexaferrite samples are magnetoplumbite hexagonal structure. The difference between radius of Fe3+ and Ga3+ ions leads to the decrease of lattice constants. As the amount of Ga substitution x increases from 0.0 to 1.4, the 4πMs and 4πMr presents a trend of increasing, but the Hc shows the opposite trend. K1 and Ha of all samples are higher than 2.5×105 J/m3 and 21 kOe respectively, which manifests all samples possess the strong uniaxial anisotropy. The materials discussed in this paper possess huge potential in the application of high frequency self-biased microwave devices.

Published: June 2021

According to the profile processing, two forming processes are proposed, i.e., multi-point stamping forming and multi-point stretch forming. Through the finite element simulation, two forming processes are simulated and compared. The analysis results show that the longitudinal springback and transverse forming error of parts by multi-point stretch forming are smaller than those by multi-point stamping forming, so the multi-point stretch forming process is suitable for processing this kind of aluminum alloy profile.

Diglycidyl ether of bisphenol A (DGEBA) epoxy resin with cycloaliphatic polyamine curing agent was modified with lignin to improve thermal and mechanical properties of of polymer composite. A systematic study of lignin loading, between 5 and 20 phr (per hundred parts resin) as compared to neat epoxy, was conducted for the reinforcement effect of epoxy resin composites. With the as-received lignin having spherical particles of 80 to 100 microns in diameter, the Tg of the epoxy-filler composites increased with a small addition of lignin up to 10 phr. Likewise, the yield stress and stiffness (Young’s modulus) of the epoxy resin-lignin composites significantly increased to a maximum value of 49.32 MPa and 2.75 GPa, respectively, with 10 phr lignin, due to the higher modulus of the filler compared to the bulk epoxy resin. Correspondingly, the storage moduli of the lignin-containing composites also increased upon filler addition up to 10 phr due to the impact of lignin. Conversely, however, the tanδ decreased in intensity with increasing lignin filler content, which reflects the dampening effect due to restricted chain mobility in thepresence of lignin particlesin epoxy systems.

Authors: Ayala Shammely , Vallejos Augusto , Arciniega Roman
Published: June 2021

In this work, a finite element model based on an improved first-order formulation (IFSDT) is developed to analyze buckling phenomenon in laminated composite beams. The formulation has five independent variables and takes into account thickness stretching. Three-dimensional constitutive equations are employed to define the material properties. The Trefftz criterion is used for the stability analysis. The finite element model is derived from the principle of virtual work with high-order Lagrange polynomials to interpolate the field variables and to prevent shear locking. Numerical results are compared and validated with those available in literature. Furthermore, a parametric study is presented.

Authors: Ccasani Jean , Eduardo Carlos , Rodríguez Jose , Carlos Eyzaguirre Acosta Augusto
Published: June 2021

The significant increase in the construction of buildings has led to the appearance of different phenomena that affect the elements that make it up. Due to their large area, in contact with the surface, solid slabs are the most vulnerable to these effects. The appearance of cracks at an early age is one of the most recurrent problems in concrete slabs, which is why it is important to counteract the presence of cracks to improve their mechanical properties to obtain buildings with greater durability. For this, the incorporation of polypropylene fibers has become one of the best alternatives to mitigate the appearance of cracks. In the present investigation, two concrete mixtures reinforced with polypropylene fibers of two lengths will be evaluated and tested for slump, plastic shrinkage, compressive strength and residual flexural strength.

To obtain an A356 aluminum alloy casting with a uniform structure and no internal shrinkage defects, ProCAST software is used to set different filling and solidification process parameters for an A356 aluminum alloy casting with large wall thickness differences, And multiple simulations are conducted to obtain optimized casting process; then, based on the process, the microstructure of the thickest and thinnest part of the casting are simulated. The size, morphology, and distribution of the simulated microstructure of the thinnest part and the thickest part of the casting are very similar. The simulated microstructure is similar to that of the actual casting. This shows that castings with uniform structure and no internal shrinkage defects can be obtained through the optimized casting process .

In this paper, performance of gravelly silty sand soil reinforced with geogrid are present and analyzed to improve the carrying capacity. For this, the geogrid was elaborated with a renewable material like bamboo with the same dimensions of polymer geogrids biaxial. This type of soil can be used for the construction of the sub-base and base of a pavement. California Bearing Ratio (CBR) tests was carried out to obtain the bearing capacity of the silty sand soil with and without bamboo geogrid. In addition, laboratory tests were carried out to obtain the mechanical properties of the bamboo. When comparing CBR results, an improvement in the bearing capacity was evidenced with the use of bamboo geogrid with a 20% increase in the carrying capacity. Finally, maximum tensile and bending strength of bamboo were 2000 kgf/cm2 and approximately 0.018 kgf/cm, respectively.

It is important to reveal the mechanism of crack growth from non-metallic inclusions because it commonly causes the origin of flaking fracture. In order to observe the cracks initiated from non-metallic inclusions under contact pressure, we performed one-point rolling contact fatigue tests using furnace-induction heated SUJ2 steel. We measured the hardness distribution of the furnace-induction heated (FIH) specimen and observed cracks with the inclusions at cross-sections.

Earphones are often exported to foreign countries by sea as consumer goods. In view of the humid marine environment, the earphone packaging box is often placed with anti-mold chips to prevent mold, while the volatilization of the anti-mold chips will also cause corrosion problems. In this study, a large number of aluminum earphone connectors were corroded in the process of ocean transportation, and the corrosion products were located in the left earphone connector close to the anti-mold chips. It’s determined that sulfate and nitrate ions lead to the corrosion of the aluminum connectors, and these are the volatilization products of the anti-mold chips. This conclusion was further confirmed by the simulation test, which was carried out on the anti-mold chips and aluminum connectors at 85 °C, 85% RH humidity for 72 h. The aluminum connectors were obviously corroded, and the morphology and composition of the corrosion products were the same as those on the actual earphones. The corrosion was successfully prevented by a PTFE coating on the surface of aluminum connectors. Keywords: Earphones; Anti-mold chip; Aluminum; Corrosion; PTFE coating

Published: June 2021

The application of ultrasonic field in the preparation of Al-Ti-C refiners can lead to the the homogenous distribution of the second phase TiAl3 and the particle phase TiC in the matrix, thus enhancing the refinement effect. In this paper, the Al-Ti-C grain refiner was successfully prepared by the ultrasonic coupling method, and its microstructure was observed. The prepared refiner was added to pure Al to verify the refining performance, and the refining mechanism was analyzed. The results indicate that the Al-Ti-C grain refiner prepared by ultrasonic field has excellent refining performance, which reduces the grain size of Al to 100 μm, and the optimum activation refining time is 3 min. The reason is that the morphology and size of the second phase TiAl3 and TiC in Al-Ti-C are changed by cavitation effect, acoustic streaming effect and thermal effect caused by high intensity ultrasonic, and the α-Al nucleates effectively under the synergistic of TiC and TiAl3 particles.
