The paper deals with the construction of exact solutions to a nonlinear heat equation with degeneration in the case of the zero value of the required function. Generically self-similar solutions and traveling wave solutions are considered, the construction of which reduces to solving Cauchy problems for a nonlinear second-order ordinary differential equation with a singularity before the higher derivative. Two approaches are proposed to solve the Cauchy problems: the analytical solution by the power series method and the numerical solution by the boundary element method on a specified segment. A complex computational experiment is carried out to compare the above two methods with each other and with the finite difference methods, namely the Euler method and the fourth-order Runge-Kutta method. Power series segments are used on the first step of the finite difference solutions in order to resolve the singularity. The comparison of the application domains, the accuracy of the solutions and their dependence on the parameters of a certain problem shows that the boundary element method is the most universal, although not the most accurate for some particular examples. The conclusions drawn allow us to construct benchmark solutions to verify the approximate solutions of the nonlinear heat equation by various methods in a wide range of parameter values.

The Paradigm Wars: Is MMR Really a Solution?
Authors: Williams Ryan Thomas
Published: February 2021

Educational research has several competing views of the social sciences, and these are often referred to as paradigms. Hammersley (2013, p. 13) portrays paradigms as ‘not simply methodologies; they are ways of looking at the world, different assumptions about what the world is like and how we can understand or know about it’.  The paradigm wars’ boils down to a simple conflict between academics and scholars of qualitative and quantitative research which concerns the relative merits of the different perspectives. In the 1980s, the objectivity-seeking quantitative researcher diminished, whilst, post positivists, interpretivists, and critical theorists flourished throughout this same period. Mixed methods research (MMR) combines elements of both qualitative and quantitative approaches and has often been branded as a ‘transformative paradigm’. The importance of MMR means that the author can combine knowledge sets and move away from one’s allegiance to a particular research perspective. This review of literature will examine the paradigms that are commonly associated with education research. There is an active debate in the research community on the paradigms wars, and this will also be examined in relation to MMR.
A Systematic Review of the Continuous Professional Development for Technology Enhanced Learning Literature
Authors: Williams Ryan Thomas
Published: February 2021

There is a large body of international research on raising the quality of education, with particular emphasis on CPD to support professional and pedagogical growth. From an educator’s perspective, there is widespread agreement that effective CPD is an important component of educational success. Therefore, it is unsurprising that research interest in this area has grown, particularly in light of the digital agenda. In a TEL context, educators report one of the main barriers to effective use is the lack of training in this area. This review of literature will examine some of the key ideas that form successful TEL CPD delivery, more specifically with relation to transformative models of CPD. Likewise, the section attempts to understand the context in which educators are operating and make sense of the challenges that relate to continuing professional development (CPD). In order to fully explore this phenomenon, personal development (PD) frameworks are explored, with a specific focus on Aileen Kennedy’s (2005) 9 typologies.

Published: February 2021

The present experiment was designed to study the histoarchitectural changes in the liver following lactational lead (Pb) intoxication in rats. A total of 12 adult female and 4 male rats were used in the experiment and 32 offspring for the analysis of lactational lead intoxication. The offspring were divided into four groups. Groups B, C and D were administered 10 mg/dL, 30 mg/dL and 70 mg/dL of lead acetate respectively, via drinking water for 21 days through the lactating mothers while group A was control. The livers of the pups were observed using histological methods. One-way ANOVA was used to analyze data, followed by Tukey post hoc test for multiple comparisons. The results from the analysis showed that the total body weight, body length and liver weights were only slightly altered in the Pb intoxicated groups. Using relative liver weights alone revealed some form of hepatomegaly among the experimental groups. The results revealed a dose-dependent increase in blood lead concentration. Histopathological evidences revealed moderate to severe histoarchitectural distortions along Pb concentration gradient. Lactational lead intoxication portends dose dependent histopathological changes in the liver of SD rats.

Published: February 2021

This study was carried out to investigate the effects of Tetracarpidium conophorum on iron overload-induced cardiac toxicity in wistar rats. A total of 30 rats weighing between 170-245g were divided into six groups (A, B, C, D, E and F) of five per group. Group A (control) was administered 1ml of distilled water, group B, C, D, E, and F were induced with iron (II) chloride for thirty days and treated with different doses of the extract except group B for thirty days, group F was treated with standard drugs at the same time interval, using orogastric tube. After last day of administering drugs, the rats were left for an overnight fast and then sacrificed 24 hours later. Blood tissue samples were collected through cardiac puncture and immediately transferred to EDTA sample bottles for iron level and total iron concentration tests. 2ml was transferred into plain sample bottles for oxidative stress test analysis. Free radical scavenging activities, lipid peroxidation, haematological indices, body and heart weight and histological studies analysis were accessed. Results shows that there was significant increase (p<0.05) in body weight and no significant change in organ weight. These show that Tetracarpidium conophorum extract when mildly consumed has healing effect on damages heart induced by iron (II) chloride. It also proves anti-inflammatory activity of walnut. Histological slides showed vascular ulceration, erosion and stenosis of coronary artery in group B treated with only iron (II) chloride while other groups were normal. There was no significant change in anti-oxidant enzymes activities, except glutathione peroxidase that significantly increased in group F treated with high dose of the extract. However, graded doses of Tetracarpidium conophorum and standard drug reversed the lesions induced by iron (II) choride. Tetracarpidium conophorum extract has ameliorating effects on iron (II) chloride-induced heart damage.

This paper addresses the issue of transferring L2 prosody teaching to online settings due to the lockdown. The reasons are provided to account for the vulnerable status of pronunciation teaching and related risks. We report the results of the research project carried out in Moscow Institute of Physics and Technology with forty Russianspeaking engineering students. In this study a combination of qualitative and quantitative research methods was used. The study first provided a critique of preexisting computer-based pronunciation training (CAPT) options ensuring learning continuity. These options were then analyzed against global educational policies related to the impacts of the COVID-19 pandemic. Based on this understanding, a methodological framework was designed to bridge the gap between prosody teaching goals and digital tools. At the next stage, experimental teaching was conducted to evaluate the feasibility of this framework. Once data from the interviews, rating scales and participant observation were collected, a descriptive analysis of the results was given. The findings showed that the suggested training had an important effect on L2 prosody acquisition by engineering students

The article is devoted to the study of the effectiveness of organizing independent work in a foreign language lesson in high school using the example of home reading in a remote format in a situation of forced isolation. The situation with the coronavirus pandemic and forced isolation requires a rethinking of the process of teaching foreign languages, the adaptation of traditional methods and the development of new methods for remote work. The article discusses the importance of students' independent activities in the process of teaching a foreign language. The peculiarities of formation of communicative competence in the process of learning a foreign language are revealed. It describes the process of organizing home reading in English lessons, and analyzes the practical formation of communicative competence in the process of independent work in English lessons on home reading in a remote format. The specifics of the organization of home reading in the English language lesson at the level of basic general education based on the English Language educational and methodological complexes (EMC) (6th grade) and the tutorial Home reading is established. The theoretical significance of the study results is to replenish the idea of the effectiveness of the process of organizing home reading and the formation of communicative competence among secondary school students on the materials of home reading lessons in conditions of forced isolation. The practical value of the work lies in the analysis of a universal teaching manual for the formation of communicative competence in a remote format as part of independent work in English lessons for secondary school students in the aspect of home reading on the material of short stories.

Published: February 2021

During the Covid-19 outbreak in 2020, students of all education levels are pushed to study at home via online classes. Schools, universities and other educational institutes have to make sure that their students can keep receiving knowledge and information based on the indicators set by the curriculum. The same thing also occurs at the English Education Department of Syiah Kuala University in Banda Aceh, Indonesia. This article presents the results of a two-cycle action research project conducted in Banda Aceh, Indonesia, through an online learning platform using Zoom meeting. In this study, eight undergraduate students participated in the online intervention class to apply genre-based visualization metacognitive strategy. A total of six academic texts of the explanation genre were taken from TOEFL tests and used in both cycles. In the online intervention class, students generated visual imagery of the academic texts, built up their knowledge of the text genres in the online discussions, and individually drew visual representations of the explanatory texts. The images drawn by the students were taken for the qualitative analysis, and the tests given to the students were analyzed quantitatively. Both data are used to find out their improvement in reading comprehension. The findings of this study revealed a remarkable contribution of genre-based visualization for improving students' comprehension of academic texts of the explanation genre at TOEFL level, particularly through online learning during the pandemic.
Teaching online enantiosemia and word diffusion aspects during the coronavirus pandemics
Authors: Nurtayeva Aisulu , Abdirassilova Gulmira , Karbozova Makbal , Suer Eker , Rakhimzhanova Sandugash
Published: February 2021

The article’s primary goal is to demonstrate in the online teaching of language the philological aspects of the system and patterns of the occurrence of enantiosemia in the language to students. The article shows how language theoretical aspects can be taught in online learning. It also gives definitions of enantiosemic words for this purpose: to study their origin in the language system; to analyze the position in the text due to a change in syntactic meaning; tasks such as determining the nature of word formation, the study of the lexical stability. Enantiosemia occurs mainly in the form of interstitial diffusion. We use words in the form of opposite meanings during the speech, which are then stabilized and translated into a symmetrical second meaning. The study considers the secondary meaning transition through semantic analysis, contrasting, oppositional, and component analysis. We support the idea of developing the meanings of words being determined by the method of cognitive analysis. Thus, when instructing students to study the nature of enantiosis that acquire a new meaning that can be both stable or unstable in the language, it is necessary to do it in a context-sensitive manner and supplement the vocabulary.

Published: February 2021

Objective: There are various clinical scoring systems in acute tonsillopharyngitis. The Modified Centor Score was developed to predict streptococcal pharyngitis and the Mistik score was developed to diagnose viral agents. This study aimed to determine cut-off values of the Modified Centor Score and Mistik score according to rapid antigen detection test (RADT) results of patients admitted with sore throat in the primary care and evaluate the use of these scoring systems by family physicians.
Methods: A total of 125 patients between the ages of 3 and 80 who were admitted with sore throat to the family health centers were included in the study. Physical examinations of the patients were performed and their Mistik and Modified Centor Scores were detected. Patients underwent RADT. Treatments of the patients were recorded. In the second stage of the study, patients underwent clinical scoring and the physicians completed a questionnaire to evaluate the use of the Mistik Score, Modified Centor Score and RADT.
Results: The optimal cut-off value for the Modified Centor Score was 3, sensitivity was 87.5%, specificity was 86.2%, positive predictive value was 48.3% and negative predictive value was 97.9%. The optimal cut-off value for Mistik score was 3, sensitivity was 61%, specificity was 87.5%, positive predictive value was 97% and negative predictive value was 25%. Of the physicians, 75% used clinical scoring during routine examination and the most common scoring system used was the Modified Centor Score (88.9%). Of the physicians, 75% used clinical scoring before the decision of RADT.
Conclusion: The use of clinical scoring systems such as the Mistik Score and Modified Centor Score will primarily allow RADT be used in the appropriate patient for sore throat that is very common in daily family practice. In addition, it will help family physicians decide on the best treatment options for tonsillopharyngitis. Therefore, we recommend the use of clinical scoring systems especially the Mistik Score, which is a viral scoring system.

Published: February 2021

Finland’s community pharmacy system provides an example of a privately-owned regulated system being proactively developed by the profession and its stakeholders. Community pharmacists have a legal duty to promote safe and rational medicine use in outpatient care. The development of professionally oriented practice has been nationally coordinated since the 1990s with the support of a national steering group consisting of professional bodies, authorities, pharmacy schools and continuing education centers. The primary focus has been in patient counseling services and public health programs. The services have extended towards prospective medication risk management applying evidence-based tools, databases and digitalization. Research has been essential in informing progress by indicating high-risk patients, medications, practices and processes needing improvement. Despite the commitment of the profession and pharmacy owners, large-scale implementation of services has been challenging because of lack of remuneration, the pharmacy income still consisting primarily of sale of prescription and nonprescription medicines. Policy documents by the Ministry of Social Affairs and Health have supported the extension of the community pharmacists’ role beyond traditional dispensing to promote rational pharmacotherapy. The current roadmap by the Ministry of Social Affairs and Health emphasizes ensuring adequate regional availability and accessibility of medicines, regardless of the future pharmacy system. It also emphasizes the importance of strong regulation on pharmacy business operations and sale of medicines to ensure medication safety. At the same time, the roadmap requires that the regulation must enable implementation of new patient-oriented services and procedures, and further promote digitalization in service provision. Competition and balance of funding should be enhanced, e.g., through price competition, but the risk of pharmaceutical market concentration should be managed. The regulation should also consider influence of the new social and health care system on drug delivery. Year 2021 will be crucial for making long-term political decisions on the future direction of tasks and finances of Finnish community pharmacies in this framework. Government-funded studies are underway to guide decision making. Ongoing Covid-19 crisis has demonstrated the readiness of Finnish community pharmacies to adapt fast to meet the changing societal needs.
Effect of the tunneled-cuffed central venous catheters on oxidative stress indices and inflammation in chronic hemodialysis patients
Authors: KORUCU Berfu , YETER Hacı Hasan , BALİ Elif Burcu , DERİCİ Mehmet Kürşat
Published: February 2021

Objectives: The use of central venous catheters as hemodialysis (HD) vascular access is associated with worse morbidity and mortality in HD patients. This occasion is often attributed to comorbidities of the patients with central venous catheters. Studies reveal that a biofilm layer occurs on most of the tunneled-cuffed central venous catheters (TC-CVCs). This study aimed to determine the oxidative stress (OS) and systemic inflammation (SI) status in patients with TC-CVCs as HD vascular access without clinical signs and symptoms of infection.
Methods: The study is composed of eighty-five patients with a minimum HD vintage of one year. Patients with a history of infection or a cardiovascular event within six months, malignancy, systemic inflammatory diseases, or malnutrition were excluded. OS indices and SI markers were studied and compared in patients with arteriovenous fistula (AVF) and TC-CVCs.
Results: Mean native thiol/total thiol (NT/TT) ratio was significantly higher and mean disulphide/total thiol (DT/TT) ratio was significantly lower in AVF group comparing TC-CVC group (0.46 ± 0.17 and 0.36 ± 0.17, p = 0.03 for NT/TT; 0.27 ± 0.08 and 0.31 ± 0.08, p = 0.04 for DS/TT; respectively). Mean OS index was significantly lower in the AVF group comparing TC-CVC group (0.15 ± 0.14 and 0.24 ± 0.23, p = 0.04; respectively]. Median hs-CRP levels and median IL-6 levels were significantly lower in AVF group comparing TC-CVC group (5.8 [min: 3.0-max: 82.5] mg/L and 9.7 [min: 3.0-max: 45.4] mg/L, p = 0.004 for hs-CRP; 6.2 [min: 2.0-max:159.0] pg/mL and 12.2 [min: 2.6-max: 41.3) pg/mL, p = 0.01 for IL-6; respectively).
Conclusions: TC-CVCs inversely affect OS and systemic inflammatory status in HD patients, presumably due to foreign body reactions and biofilm layers.

Cycle of novellas “Bruderschaft with Death” by B. Akunin in the aspect of literary cinematic
Authors: Osmukhina Olga Y. , Kuryaev Ilgam R.
Published: February 2021

We consider the implementation of the literary cinematic principles in Boris Akunin’s cycle “Bruderschaft with Death”, which we analyze using intertextual, contextual methods, as well as the method of holistic analysis of a literary work. We substantiate that “novel-cinema” as a new form, which is the result of intermedial interaction (one of the key processes of the modern cultur-al space) contributes to the assertion in the texts of novellas to develop “visible”, dynamic action emphasized in the visual space, constructed through the characters system and utilitarian editing. We establish that in B. Akunin’s text there is a corpus of visual material (posters, illustrations, photographs) that asserts a specific visual image of the events described. However, the existence of such a visual corpus contributes to the generation of additional semantics, which changes the emphasis in the “visual – verbal” relationship. As a result, we conclude that in the novellas of cy-cle not only the main provisions of “literary cinematic” are realized, but the text itself appears as secondary in relation to the primary visual matter, to the conditional pre-, post- or postrevolution-ary “film”, the existence of which is indicated by the presented corpus of illustrations and photo-graphs. Research materials and general conclusions can be used to analyze not only other works of B. Akunin, but also modern domestic and world literature in the context of intertextual and inter-mediate interaction.
Linguodidactical potential of modern feature films in Russian as a foreign language classes
Authors: Melnik Yuliya A. , Russu Kseniya R.
Published: February 2021

The work is devoted to the formation of sociocultural and linguocultural competences of foreigners studying Russian as a foreign language (RFL) through work with modern feature films. We describe the linguodidactic potential of authentic video materials designed to work in the classroom in Russian as a foreign language; selection criteria are presented. We point out that mo-tion pictures are a valuable source of both linguistic and extralinguistic information. We conclude that it is advisable to use authentic full-length feature films in RFL lessons; the recommended lev-el of language proficiency is B1. We offer a methodological development for the Russian film “Moscow Romance” (2019). We substantiate the criteria for choosing this film, we have devel-oped a system of tasks, some of which can be completed during extracurricular hours. We pre-scribe such stages of work with the film as: “Pre-demonstration. Preparation for viewing”, “Dem-onstration. Understanding Test” and “Post-Demonstration. Discussion”, as well as offer the fourth stage “Continuing work outside the classroom”. This system of work has been tested by the au-thors of the work in three groups of different nationalities studying at Russian universities.
Implementation of the sociocultural competence of “students” in speech in their native and foreign languages
Authors: Tsurtsilina Natalia N.
Published: February 2021

It is well known, that by using language any text reflects the achievements of culture as a product of people’s social activity, that is, the sign system of the language makes it possible to convey the content of culture. Thus, we establish that when comparing different languages in the working process with the corresponding texts, the recipients of textual information acquire the specificity of certain cultures and the singularity of those languages through the prism of which the nature and content of these cultures is transmitted. We note that a full-fledged intercultural dialogue largely depends on students’ assimilation of the cultural code inherent in the linguistic society of the target-language country. We provide definitions of the constantly supplemented and still open concept of “culture”, formulated by foreign and domestic cultural experts. We state the position that a broader understanding of culture cannot be interpreted without close connection with the particular people’s life, without taking into account the differences between representatives of different peoples. We give concrete examples of how the reality reflected in texts through images not only allows us to better understand and comprehend it, but also affects various characteristics of the person receiving this information. We confirm the position that the study of foreign lan-guages has an impact on the development of the personality mental world, enriches it with know-ledge of a foreign language culture, and is of lasting value. We conclude that the text as a product of oral and written speech characterizes the individual culture of the personality, which is devel-oped, in particular, in the learning process.
Theatricalization as a way to study the cultural space of an ethnic group
Authors: Nikolskaya Tatyana M.
Published: February 2021

We consider the issue of the theatricalization concept and its role for a general cultural space understanding of an ethnic group, in terms of basic cultural concepts. We point out the main tasks that the theatricalization method should perform. The interrelation is traced from a simple movement in the mimes’ face to a theatrical performance complex in composition, often asso-ciated with a huge number of effects. We focus on the fact that theatricalization helps to form an associative perception of ethnocultural reality. We prove that due to this phenomenon, immersion in ethnocultural reality acquires a meaningful character and contributes to development of peculiar idea of people’s cultural code. We provide examples, accompanied by illustrative material, confirming the fact that not only small theatrical forms, but also integral theatrical performances contribute to the creation of a holistic picture of the cultural code of an ethnic group, and direct tactile perception once again helps in this process. In addition, it is substantiated that this method also contributes to the implementation of intercultural communication. We conclude that theatricalization combines both art and other types of activity that contribute to a faster, easier, and most importantly, a intimate understanding of the cultural space of a particular ethnic group.
Perception of Russia’s image in China in the context of “One Belt and One Road”
Authors: Liwei Zhang
Published: February 2021

We prove that the positive perception of Russia’s image in China is strengthened in the context of the creation of global transport and investment infrastructure “One Belt and One Road”, which expands the China-Russian relations, strengthens a propitious atmosphere for the economic development of two countries. We propose an attempt to study the reasons for the spread and strengthening in modern China of a positive image of “Russia” with a rich educational image, nat-ural resources and cultural traditions, which for many years was perceived by the Chinese as a country of balalaikas, bears and vodka. We substantiate that the Russia’s image in China is built on the basis of acquaintance with the traditions of national culture and everyday culture. We note that a special role in understanding the image of the country is played by the cultural and linguistic stereotype, which is formed on the basis of the proper name, which contains an evaluative and associative component. We emphasize that the phenomenon of the anthroponym allows us to identify its pragmatic feature, which helps to clarify the subjective perception of a certain person by a native Chinese speaker, and the cultural properties of the proper name.

Introduction. Human Demodex mites (Demodex folliculorum and Demodex brevis) are ectoparasites living inside the sebaceous glands and hair follicles. In most people, their presence is of no consequence. However, several conditions or various external factors might contribute to pathological Demodex infestation resulting in demodicosis. Many different cutaneous diseases can resemble demodicosis leading to misdiagnosis.Aim. This paper aims to present information about demodicosis and provides a clear clinical portrait of demodicosis in order to distinguish it from other mimicking inflammatory dermatoses. Material and Methods. The literature search was conducted in the English and Polish language via the PubMed database and Main Medical Library. The articles regarding Demodex infestation were selected. Results. There is some evidence about the role of Demodex in the development of rosacea, blepharitis and clinical correlation between them.Conclusions. More attention should be drawn to Demodex as it plays a significant role in the development of various clinical entities in both dermatology and ophthalmology.

DORST Netshape® 4.0 – The Next Step Towards Autonomous Manufacturing
Authors: Lackner Lutz , Larsson Mats
Published: February 2021

In the production of green parts from powder, there is unavoidable slight deviation in the die filling, even when high-quality powders are used. The quantity of powder in the die varies and thus affects the weight of the compact. This filling variation results in variation of the pressing force, and thus influences the part geometry. The development of the DORST Netshape® System was conceived as an autonomous manufacturing system in order to compensate for these effects. Based on the Dorst Industry 4.0 innovations for part weight measuring immediately after pressing in combination with a laser dimension measuring system, this technology package attempts to reach enhanced precision and consistency in production. The paper presents results from various trials that show the capability of this new system, designed to improve the quality of pressed parts.
Chromatic Change in Copper Oxide Layers Irradiated with Low Energy Ions
Authors: Kobayashi Takuya , Nishiyama Fumitaka , Takahiro Katsumi
Published: February 2021

The color of a thin copper oxide layer formed on a copper plate was transformed from reddish-brown into blue-purple by irradiation with 5 keV Ar+ ions to a fluence as low as 1 1015 Ar+ cm–2. In the unirradiated copper oxide layer, the copper valence state of Cu2+ as well as Cu+ and/or Cu0 was included as indicated by the presence of a shake-up satellite line in a photoemission spectrum. While for the irradiated one, the satellite line decreased in intensity, indicating that irradiation resulted in the reduction from Cu2+ to Cu+ and/or Cu0. Furthermore, nuclear reaction analysis using a 16O(d, p)17O reaction with 0.85 MeV deuterons revealed a significant loss of oxygen (51015 O atoms cm–2) in the irradiated layer. Thus, the chromatic change observed in the present work originated in the irradiation-induced reduction of a copper oxide.

This research illustrates modification of multi-walled carbon nanotubes (MWCNT) by ZrO2/Pb to construct nanocomposites (MWCNT/ZrO2/Pb-NCs) by simple precipitation technique and subsequently examine its ability for adsorption of Amido black (AB) and Eosin B (EB) dyes in binary system. The present nanocomposites investigation by FESEM, XRD, FTIR, and EDX analysis, reveal its as-synthesized crystalline nature with cubic morphology and average particle size 30–50 nm. The present nano-adsorbent represent high efficiency for AB and EB adsorption from aqueous solution, while dependency of variables including pH, initial concentration of dyes, contact time and MWCNT/ZrO2/Pb-NCs mass were analyzed by central composite design (CCD). The predicted maximum removal percentage was 95% removal for both dyes is consequence of adjustment of operational conditions at pH of 6.0; 0.05 g MWCNT/ZrO2/Pb-NCs; 15 min stirring at 15 mg L-1 for both dyes. The Langmuir as applicable for representation and description of reveal data of adsorption with adsorption capacity of 15.46 and 16.92 mg g-1 for AB and EB, respectively. Pseudo-first order model owing to its high correlation coefficient and closeness of experimental and theoretical data well represented behavior of corresponding adsorption system. Mechanism examination strongly proof high contribution of external mass transference as the main rate-controlling step. The successful regeneration of MWCNT/ZrO2/Pb-NCs suggested their usefulness in wastewater treatment and its ability of environmental management.

Metal-supported fuel cells (MSCs) offer potential material cost and robustness advantage over anode supported cells (ASCs). Because of the very good thermal shock stability of such MSCs, these can be heated up very quickly. However the challenge co-firing of metal substrate and electrolyte stays still unsolved. The production of the core component, the tape casted metal substrate, with defined shrinkage resulting from modification of metal powders is presented in the paper. This approach leads to an adjustment of the shrinkage mismatch during sintering, between metal and ceramic components, and adjustment of target specifications like porosity, green density and layer thickness.

Authors: Fazio Riccardo , Jannelli Alessandra
Published: February 2021

This paper deals with a non-standard finite difference scheme defined on a quasi-uniform mesh for approximate solutions of the Magneto-Hydro Dynamics (MHD) boundary layer flow of an incompressible fluid past a flat plate for a wide range of the magnetic parameter. We show how to improve the obtained numerical results via a mesh refinement and a Richardson extrapolation. The obtained numerical results are favourably compared with those available in the literature.
