The Dialogic Aspect of Soft Law in International Insolvency: Discord, Digression, and Development
Authors: Pottow John
Published: February 2022

In this study, I describe three important articles in the IRJ model law and discuss their development, drawing in part upon my experience as a delegate to UNCITRAL Working Group V. In doing so, I want to situate these developments within the broader discussions of international law and international relations theory regarding soft law. Doing so will both vindicate and puzzle some of the conventional understanding of how soft law instruments tend to function, although some of the conclusions must necessarily be conjectural at this stage.

Promoting Predictability in Business: Solutions for Overlapping Liability in International Anti-Corruption Enforcement
Authors: Bulovsky Andrew
Published: February 2022

This Note evaluates solutions to the problems of overlapping liability in general and multi-jurisdictional disgorgement in particular. Part I traces the origins of international anti-corruption efforts and provides an overview of the Foreign Corrupt Practices Act (the “FCPA”). It then discusses the two most significant international anti-corruption conventions: the OECD’s Convention on Combatting Bribery of Foreign Officials in International Business Transactions (the “OECD Convention”) and the United Nations Convention Against Corruption (“UNCAC”). Part II lays out the problems created by the lack of a formal mechanism to prevent overlapping liability— a phenomenon that violates the common law concept known as double jeopardy and the analogous civil law principle ne bis in idem (not twice in the same thing). Part III proposes a formal mechanism to militate against the problems noted in Part II and argues that these provisions should be housed in a series of bilateral agreements akin to those that exist in international antitrust enforcement. Ultimately, this Note stresses the need for a more proportional and predictable method of ensuring that MNCs are not subject to overlapping liability and provides an actionable means for doing so.

Turkish Women in Science during the Totalitarian Regime in Bulgaria (Mefkure Mollova, Hayriye Memova, Zineti Nurieva)
Authors: Muratova Nurie
Published: February 2022

The article aims is to trace the life and scientific adaptation of three women from the Turkish community in Bulgaria who were engaged in science during the communist period.They are the only ones from the Turkish community in Bulgaria who during the communist period were engaged in science in the field of humanities. The three have different destinies in science and life, fully determined by the political circumstances and their decisions and choices. Two of them have their scientific careers interrupted - Mefkure Mollova, who refuses to give in to the political pressure of the regime and is expelled from the university and all scientific institutions in the country for the rest of her life; Hayriye Memova, who for a long time follows the rules of the regime until they asked her for an impossible compromise. The third is Zineti Nurieva, who fits into the regime and even supports and works for it. Eventually, all three women complete their scientific and life paths abroad, as emigrants.The study is based on documents from the secret archives of the State Security, memories and personal testimonies. This is so because during the communist regime the documents about the Turks were destroyed and today it’s difficult to find such in the public archives.
Mapping the Level of Knowledge in Gender Studies: a Mirror of Women’s Radicalism in Turkey
Authors: Çubukçu Sevgi Uçan
Published: February 2022

This paper aims to map the research conducted on women and gender studies at universities in Turkey. The studies, projects, articles, books, seminars, conferences, training programs produced in this field take place in a wide variety of fields. The main material of this study is postgraduate theses written on women and gender issues. Thus, postgraduate theses written in the discipline of women and gender studies are evaluated within the framework of historical and political contexts. The institutionalization of academic feminism in Turkey is a radical intervention in the academic knowledge production process. Despite all the difficulties and obstacles, this process is a success story for Turkey. What does the knowledge of this mapping tell us? Where are these studies going? Is the radical intervention of feminism in Turkey still considered radical today? In order to think about the answers to these questions, it was tried to map the theses written on women and gender studies by taking data. In this study, the importance of the information obtained and the historical and political importance of emphasizing this information are analyzed by mapping the 'theses', which is an important part of the knowledge produced in women and gender studies in Turkey.
Decent Intellectual Work and Enlightenment of the Russian Society. Biographical Trajectories of the First Women Professional Translators in Russia
Authors: Vodenicharov Petar
Published: February 2022

The object of the study is the biographical trajectories of a "new" social group of women - the one of the professional translators, which appeared in Russia in the early 1860s. For the "new" women, the right to intellectual labor is an important duty, not only out of economic but also out of moral reasons, as an acceptable framework for women's freedom. The article examines in parallel the life trajectories of the leaders of the women's movement, who set the beginning of their civic organization of translators, or "Artel", as they call it.
Olga Gyuzeleva and the Bulgarian Cultural Elite from the Beginning of the 20th Century
Authors: Ilieva Boyka
Published: February 2022

The name of Olga Gyuzeleva is usually mentioned in connection with the history of the Sofia Opera, as she is among its founders. In addition to being among the few female members of the intellectual elite and a participant in a revolutionary cultural endeavor, fate also connected her with one of the emblematic couples in Bulgarian literature at that time – Pencho Slaveykov and Mara Belcheva. Olga was the woman who left for Brunate in the spring of 1912 to share with Mara Belcheva the hardest months after the death of the poet. Olga Gyuzeleva was the youngest of the four daughters in the family of Stephanie Gyuzeleva and Ivan Gyuzelev. Similarly to her sister, she graduated in Dresden with a degree in music. After her return to Bulgaria, she devoted herself to versatile cultural activities - an opera singer, an actress, a pianist, a teacher, and an interpreter. In 1910 or 1911, Gyuzeleva married Major Krastyu Angelov – one of Mara Belcheva’s brothers. Valuable information about her life and activity is found in her personal archive, which has not been explored yet. In the 1917/1918 season, she was a full-time actress in the National Theatre, performing parties in the operas of Gounod, Bizet, Verdi, etc. At the same time, she was teaching private solo singing and piano lessons in Sofia and Varna. In 1925, she was wounded during the terrorist attack on St. Nedelya Church. She died lonely at the age of 91 in a nursing home in Kazanlak.
Nonlinear Convective Flow of Williamson Fluid Over a Slendering Stretching Sheet with Melting Heat Transfer
Authors: Mocherla Gayatri  , Konda Jayarami Reddy  , Bommanna Lavanya
Published: February 2022

The main concern of this paper is to analyze the nonlinearity of the Grashof numbers (thermal and diffusion) on the Williamson fluid flow across a stretching sheet with non-uniform thickness with the consideration of melting heat transfer. The modelled equations are non-dimensionalized with the utilization of similarity transformations. We used shooting technique based on Runge-Kutta 4th order method to unriddle the ensuing equations. Influence of key parameters on the common profiles i.e., velocity, temperature and concentration are deliberated with the support of graphs. And also, we examined friction factor, local Sherwood and Nusselt numbers against the same parameters and displayed the results in tabular form. It is seen that Weissenberg number and wall thickness parameters rise the magnitude of friction factor. It is additionally qualified to specify that the temperature and concentration profiles looking high in the absence of melting parametercontrasted with the presence of melting parameter.

Time-dependent energy spectra of galactic cosmic rays (GCRs) carry fundamental information regarding their origin and propagation. When observed at the Earth, these spectra are significantly affected by the solar wind and the embedded solar magnetic field that permeates the heliosphere, changing significantly over an 11 yr solar cycle. Energy spectra of GCRs measured during different epochs of solar activity provide crucial information for a thorough understanding of solar and heliospheric phenomena. The PAMELA experiment collected data for almost 10 years (2006 June 15–2016 January 23), including the minimum phase of solar cycle 23 and the maximum phase of solar cycle 24. In this paper, we present new spectra for helium nuclei measured by the PAMELA instrument from 2010 January to 2014 September over a three-Carrington-rotation time basis. These data are compared to the PAMELA spectra measured during the previous solar minimum, providing a picture of the time dependence of the helium-nuclei fluxes over a nearly full solar cycle. Time and rigidity dependencies are observed in the proton-to-helium flux ratios. The force-field approximation of the solar modulation was used to relate these dependencies to the shapes of the local interstellar proton and helium-nuclei spectra.
A Fast Radio Burst Progenitor Born in a Galaxy Merger
Authors: Kaur Balpreet , Kanekar Nissim , Prochaska J. Xavier
Published: February 2022

We report a Giant Metrewave Radio Telescope 21 cm mapping study of the neutral atomic hydrogen (Hi) in the host galaxy of the fast radio burst (FRB) FRB 20180916B at z ≈ 0.03399. We find that the FRB host has an Hi mass of M
Hi
= (2.74 ± 0.33) × 109
M
⊙ and a high Hi to stellar mass ratio, ≈1.3. The FRB host is thus a gas-rich but near-quiescent galaxy that is likely to have acquired a significant mass of Hi in the recent past. The Hi distribution is disturbed, with extended Hi 21 cm emission detected in a northeastern tail, a counter-tail toward the south, an Hi hole between the galaxy center and the FRB location, and a high Hi column density measured close to the FRB position. The FRB host is part of a group with four companions detected in their Hi 21 cm emission, the nearest of which is only 22 kpc from the FRB location. The gas richness and disturbed Hi distribution indicate that the FRB host has recently undergone a minor merger, which increased its Hi mass, disturbed the Hi in the galaxy disk, and compressed the Hi near the FRB location to increase its surface density. We propose that this merger caused the burst of star formation in the outskirts of the galaxy that gave rise to the FRB progenitor. The evidence for a minor merger is consistent with scenarios in which the FRB progenitor is a massive star, formed due to the merger event.
Histological and Radiographical Evaluation of Deciduous Teeth during Shedding (Human and Experimental Study)
Authors: Helal Mai Badreldin
Published: February 2022

AIM: The aim of this study was to evaluate the process of deciduous teeth shedding histologically and radiographically.

METHODS: The design of the present study included both human and experimental animals. A total number of twenty human primary teeth, aged 8–10 years, were collected for light microscope and scanning electron microscopy (SEM). Furthermore, ten nameless copies of dental/occlusal X-rays of children aged 9–10 years were used to measure the radicular dentin radiodensity. For the experimental part, 4-month-old beagles were used for histological examination of the process of shedding in situ.

RESULTS: Histologically, the decalcified beagles deciduous teeth specimens showed deep resorption fossae occupied with many odontoclasts together with periodontal ligaments disorganization. Furthermore, SEM examination of human exfoliated teeth revealed variable-sized plentiful resorption lacunae with irregular edges. Interestingly, radiographic examination of the human deciduous teeth at late resorption stage revealed significant decrease in radicular dentin radiodensity.

CONCLUSION: Shedding is a complex physiological process that involves intermittent resorption of deciduous teeth supporting tissues together with significant decrease in root dentin radiodensity at late root resorption stage in comparison to other various stages of root resorption.
Multicomponent Crystal of Trimethoprim and Citric Acid: Solid State Characterization and Dissolution Rate Studies
Authors: Umar Salman , Farnandi Rido , Salsabila Hulwa , Zaini Erizal
Published: February 2022

BACKGROUND: Trimethoprim is a broad spectrum antimicrobial agent with low solubility in water which causes low bioavailability in systemic circulation.
AIM: The purpose of this study was to prepare multicomponent crystals of trimethoprim and citric acid to increase the solubility and dissolution rate of trimethoprim.
MATERIALS AND METHODS: Multicomponent crystals were prepared by solvent evaporation method. Characterizations of multicomponent crystalline solid phase properties were carried out by powder X-ray diffraction (PXRD) analysis, differential scanning calorimetry (DSC), FT-IR spectroscopy, scanning electron microscopy (SEM). Solubility and dissolution rate tests were carried out in aqueous medium.
RESULTS: The PXRD characterization results showed a new X-ray diffraction pattern in the multicomponent crystal phase. DSC analysis showed the formation of a new endothermic peak. This indicates the formation of a multicomponent crystal phase between trimethoprim and citric acid. The results of the SEM analysis indicate the formation of a new crystal habit. Solubility of multi-component crystal phase of trimethoprim increased 7 times compared to intact trimethoprim. The dissolution of trimethoprim and multicomponent crystals in 0.1 N HCl medium at 60 minutes was 56.36% and 95.57% and CO2-free distilled water medium was 43.03% and 88.26%, respectively.
CONCLUSIONS: From the results of the study, it can be concluded that the multicomponent phase of trimethoprim crystals with citric acid successfully increase the solubility and dissolution rate of trimethoprim significantly.

Published: February 2022

BACKGROUND: Indonesia, and in particular East Kalimantan, has a very high diversity of flora that has the potential to be used as traditional medicine. One type of flora is the leaves of Ficus deltoidea Jack. At present, there are no available data about the impact of F. deltoidea leaf ethanol extract on the male reproductive system.

AIM: The present study aims to investigate the effect of F. deltoidea leaf ethanol extract on several parameters of reproductive function in male mice, including changes in testicular biochemistry, reproductive hormones profile, and histopathology of the testes after subchronic exposure.

METHODS: In total, 25 male mice were divided into five groups: The control group and four treatment groups that received extract doses of 125, 250, 500, and 1000 mg/kgbw for 28 days, respectively. At the end of the treatment, surgery was performed, weight of body and reproductive organs (testis, epididymis, and seminal vesicles) were measured, and testicular biochemistry, reproductive hormone profile, antioxidant activity, and testes histopathology were analyzed.

RESULTS: In the subchronic toxicity test, there were no significant changes in body weight or in weight and relative weight of reproductive organs. Levels of testosterone, luteinizing hormone and follicle-stimulating hormone, protein, cholesterol, and activity of enzymes in the testes (alkaline phosphatase, lactate dehydrogenase, and glutamyltransferase) and activity of the enzyme superoxide dismutase increased significantly in the treated mice when compared to control mice (p < 0.05). Glycogen levels were not significantly different, but lipid peroxide (MDA) decreased significantly, though it did not change the histological structure of the testes.

CONCLUSION: Ethanolic extract of the leaves of F. deltoidea Jack does not cause toxic effects and even has a beneficial effect on the reproduction of male mice by increasing fertility, reproductive hormones, and antioxidant activity, and it does not change the histological structure of the testes.
The vegetation of Chile and the EcoVeg approach in the context of the International Vegetation Classification project
Authors: Luebert Federico , Pliscoff Patricio
Published: February 2022

Aims: Chilean vegetation has previously received considerable attention, and several classifications are currently available. The most recent of these was presented for the first time in 2006 and updated in 2017 by the authors. Although widely utilized by researchers both in Chile and Latin America, this information is only available in Spanish, which hampers its usefulness for a broader scientific audience. Here, we provide an overview of the methods and the resulting classification and propose a correspondence between Chilean classification and the International Vegetation Classification (IVC) following the EcoVeg scheme. Study area: Continental Chile. Methods: Based on the criteria of the EcoVeg approach, we established a linkage of zonal and azonal vegetation units to the macrogroup level and to the formation classes of the IVC. We also generated a map to facilitate crosswalk between the classifications. Results: We recognize 23 macrogroups, 13 divisions and 11 formations of zonal vegetation, including three newly proposed macrogroups, one division and one formation. We further recognize 23 macrogroups, 23 divisions and 17 formations of intrazonal vegetation. Together, they encompass all six formation classes of natural vegetation of the IVC. We highlight those units so far not mentioned for Chile in the IVC. Finally, we provide a map of macrogroups and discuss the limitations and prospects of this approach for the classification of Chilean vegetation. Conclusions: Chilean zonal vegetation was successfully accommodated in the IVC down to the macrogroup level. The process of linking Chilean zonal vegetation and macrogroups led us to a few suggestions that may be used to improve the IVC.

Nursing Delegation in the United Kingdom
Authors: Gillen Patricia , Graffin Sean
Published: February 2022

This article describes how registered nurses in the United Kingdom (UK) delegate some nursing activities to support workers who assist them in providing nursing care. The global shortage of qualified nurses and the ageing nursing population has resulted in a growing dependency on non-qualified personnel to provide certain aspects of patient care within the care setting. The authors begin this article by presenting the differing nursing staff roles in the UK along with the legal and professional aspect of delegation. Next they discuss the benefits, facilitators, and barriers. They conclude by describing the changes in role expectations, the variety of nursing settings in which delegation occurs, and nursing delegation challenges within the UK.

Uncemented Collared Femoral Stems in Total Hip Arthroplasty
Authors: Lemme Nicholas J. , McDonald Christopher L. , Hamilton William G. , Crisco Joseph J. , Cohen Eric M.
Published: February 2022

The procedure of total hip arthroplasty (THA) is rapidly evolving. Patients undergoing THA are younger and more active, and they demand an earlier return to their daily activities. All of these factors increase both the early forces on uncemented femoral stems and the risk for complications. Consequently, surgeons must choose implants that provide immediate primary stability. This has led to renewed interest in the use of uncemented collared stems, which have benefits including increased primary stability, decreased risk of subsidence and periprosthetic fracture, and improved load transfer to the proximal femur.

Preoperative Transcutaneous Oxygen Perfusion Measurements in Predicting Atraumatic Wound Healing After Major Lower Extremity Amputation
Authors: Noori Naudereh , Haruno Lee , Schroeder Ian , Vrahas Mark , Little Milton , Moon Charles , Lin Carol
Published: February 2022

This study examined the correlation between preoperative transcutaneous oxygen perfusion (TcPO
2
) measurement and the success of wound healing after major lower extremity amputation. There is no validated consensus on how to accurately determine appropriate amputation levels. A TcPO
2
greater than 30 to 40 mm Hg is widely cited as a positive predictor of postoperative wound healing, but its validity has not been well defined. A retrospective chart review was performed for patients who underwent above-knee amputation (AKA), through-knee amputation, or below-knee amputation (BKA) at a single institution from 2012 to 2018 with preoperative TcPO
2
values and a minimum 30-day postoperative clinical follow-up. This review yielded 141 total amputations: 93 BKAs, 6 through-knee amputations, and 42 AKAs. Fifty-five amputations were unsuccessful, defined by postoperative wound dehiscence or infection. Of these, 37 were BKAs, 4 were through-knee amputations, and 14 were AKAs. There was a significant difference in preoperative TcPO
2
between the successful and unsuccessful amputations, at 46.2 and 38.3 mm Hg, respectively (
P
=.02). A TcPO
2
of 30 to 40 mm Hg showed a 68.8% success rate, and a TcPO
2
of less than 20 mm Hg showed an 18.2% success rate. A receiver operating characteristic curve for TcPO
2
predicting amputation success had an area under the curve of 0.53 for AKAs and 0.61 for BKAs; the diagnostic ability is far from prognostic. There is no linear association between TcPO
2
and success rate. A TcPO
2
of less than 20 mm Hg has a high positive predictive value for failure, but higher levels are not 100% predictive of wound healing success after amputation, as previously reported. [

Risk of Instability After Revision Total Knee Arthroplasty for Periprosthetic Joint Infection
Authors: Menken Luke G. , Berliner Zachary P. , Korshunov Yevgeniy , Cooper H. John , Hepinstall Matthew S. , Scuderi Giles R. , Rodriguez Jose A.
Published: February 2022

Periprosthetic joint infection (PJI) remains a major source of morbidity after total knee arthroplasty (TKA). The risk of recurrent infection has been more extensively studied than the risk of mechanical failure. We sought to define the incidence of instability after revision TKA for PJI and to compare this incidence with that for revision TKA for instability. We retrospectively reviewed patients treated by 4 arthroplasty surgeons at 1 institution. The primary outcome was a new diagnosis of clinical instability after index revision. We analyzed potential risk factors that may contribute to postoperative instability after PJI, including demographic characteristics, implant alignment, number of previous procedures, level of constraint during index revision, and type of spacer used. Patients were matched 1:1 with patients undergoing revision TKA for instability. Continuous variables were compared with Student's
t
test for normally distributed variables and Mann-Whitney
U
test for non-normal variables. Categorical variables were compared with Fisher's exact test. Thirty-seven patients who underwent revision TKA for PJI were identified. Twelve (32.4%) had clinical instability after revision, compared with only 3 (8.1%) in the matched cohort (
P
=.019). Use of a revision, midlevel constraint device in the PJI cohort did not correlate with a lower risk of instability (
P
=.445). A greater number of previous surgical procedures increased the likelihood of instability (
P
=.041). Revision TKA for PJI is associated with a high risk of subsequent instability. Midlevel constrained implants may not be sufficient to prevent instability. A focus on soft tissue tension and a lower threshold for increasing constraint may be prudent in this cohort. [

Nursing Students and Cognitive Rehearsal Training as an Antibullying Strategy: A Canadian National Study
Authors: Carissa Fehr Florriann , Seibel Michelle
Published: February 2022

Background:

Bullying in nursing is a well-documented phenomenon and is a factor in job satisfaction, nurse retention, and client safety. Both nursing students and nursing staff experience these negative interactions in clinical settings.

Method:

This study was conducted to refine and improve the cognitive rehearsal training (CRT) intervention. Experiential workshops were conducted with third-year or equivalent baccalaureate nursing students at five different schools of nursing across Canada (
N
= 329).

Results:

Students supported the CRT approach as a first response toward dealing with bullying behavior in the health care workplace and offered advice for its improvement.

Conclusion:

Currently, schools of nursing and health authorities typically use theoretical and online approaches to address bullying. The CRT intervention described in this study is novel as it involves role-play, which promotes learning at a deeper level than didactic approaches.

Évaluer l’efficacité de l’éducation relative au changement climatique en milieu non formel : une étude de cas
Authors: Champagne St-Arnaud Valériane , Samson Ghislain
Published: February 2022

Les outils permettant d’évaluer l’efficacité de l’éducation relative au changement climatique en milieu non formel sont peu nombreux et souffrent souvent de l’absence d’assises théoriques solides. Dans le contexte de la campagne Sors de ta bulle menée par la Fondation Monique-Fitz-Back, un cadre d’évaluation novateur reposant sur douze indicateurs a été élaboré. Ces indicateurs ont servi à évaluer les effets de la participation de jeunes de 12 à 17 ans au Sommet jeunesse sur le changement climatique, l’une des activités de la campagne. Un devis mixte combinant la réalisation d’une enquête en ligne auprès des participant.e.s et un entretien de groupe avec douze d’entre eux a permis de constater que la campagne Sors de ta bulle a contribué à stimuler efficacement le processus d’adoption de comportements écoresponsables selon trois axes : augmentation de la motivation, renforcement du sentiment d’efficacité personnelle et intensification de l’engagement dans la lutte climatique.

Les défis soulevés par les changements climatiques sont de plus en plus importants et préoccupent un nombre grandissant d’individus. Certains ressentent une urgence d’agir, comme une responsabilité sociale : il faut mener dès maintenant des actions concrètes dans l’espoir de gérer la crise. En raison du fait que les actions individuelles, bien que pertinentes et nécessaires, n’ont pas les effets espérés par la personne qui les mènent, plusieurs vivent de l’éco-anxiété. Afin de canaliser cette écoanxiété, cet article présente onze stratégies d’adaptation, en fonction de trois axes prioritaires : les émotions, le problème et la signification.

Communities of practice foster sharing of knowledge in the organisations. For the creation of such an organisational-level practice community, a motivating environment for the development of such practice communities should be created by the support perspective among co-workers, supervisors, and the organisation. The present study examines the relationship between Co-Worker Support and Communities of Practice with mediating role of Personal Interaction. The data was collected from 178 respondents representing the manufacturing and service sector Indian Organisations with various demographic characteristics. In accordance with the hypotheses developed, the findings supported the hypotheses. The structural equation modelling showed the path from co-worker support to communities of practice is mediated by Personal Interaction with highly significant results. The theoretical and managerial implications concerning the importance of support, most importantly co-worker support, are mentioned in the study. Future scope of research is suggested based on the current findings of this study.

One of the promising ways to reduce the content of organic pollutants in natural waters is the use of biological processes in combination with sorption on powdered activated carbon followed by membrane filtration and, as the final stage, disinfection of the obtained permeate by direct electrolysis. The paper presents the results of the efficiency of purification of the Don water, which underwent physicochemical treatment from halogen-organic contaminants in a biosorption-membrane reactor and the dependencies characterizing the disinfection of water by direct electrolysis in a flow-through membraneless electrolyzer. The studies were carried out using powdered active carbon, hollow fiber, and flat plate membranes. An oxide iridium-ruthenium titanium anode (OIRTA) was used as electrodes in a flow-through electrolyzer. As a result of processing the experimental results, the efficiency of removing not only the turbidity and color of water, but also organic substances, which cause high permanganate oxidizability and COD, has been established. The results of experimental studies have shown a high efficiency of purification and disinfection of natural water to the requirements of SanPiN. The efficiency of COD reduction was on average 41.2%, color - 57.3%, permanganate oxidizability - 33.3%.

Published: February 2022

The aim of this investigation was to study the influence of Nb-enriched powder mixtures on structure and oxidation resistance of protective layers based on Ni-based self-fluxing alloy, produced by non-vacuum electron beam cladding technique on low-carbon steel substrates. The oxidation resistance of coatings was studied by thermogravimetric analysis (TGA). The samples held at 900°C for two hours in air atmosphere. TGA results indicate that the highest oxidation resistance has the material, obtained by cladding of pure Ni-based self-fluxing alloy. Samples, produced by cladding of Ni-based self-fluxing alloy in combination with Nb-enriched powder mixtures demonstrate lower level of oxidation resistance. Structure of the coatings was characterized by optical and scanning electron microscopy combined with electron microprobe analysis as well as X-ray diffraction.

Published: February 2022

The work is devoted to the analysis of the effect of holes made using various technologies on the strength of orthogonally reinforced fibrous composites. Comparison of data obtained by finite-element modeling with results of tensile experiments of composite plates with holes is given. It has been experimentally confirmed that drilling holes in fibrous composites is unacceptable: when making holes, fibers must be expanded at the stage of molding the composite element. It has also been shown that it is possible to model, if not the fiber structure itself, but the properties of the material next to the hole using the built-in functions of FEA programs.

Published: February 2022

Interaction at the interface during the production of functional steel-aluminum compositions by arc processes has been investigated. Regularities and mechanisms of the diffusion zone formation have been proposed upon contact of a melt based on aluminum, alloyed with 11-13 wt% Si, with the steel substrate or Al-Fe system intermetallic compounds. It was found that the presence of Si in the composition of filler material leads to diffusion mobility of Al and Fe decreasing due to the replacement of Al, as well as the occupation of structural vacancies in double FexAly intermetallics and ternary intermetallic phases with different stoichiometric composition FexAlySiz formation. It was determined that during the arc cladding process using as substrate the steel with intermediate zinc coating, a diffusion zone with an average thickness of 7 μm is formed, while in the presence of an intermediate coating from aluminum deposited by the “cold metal transfer” process, its average thickness is 18 μm.

The paper provides an assessment of the safety processes of high-modulus energy sources systems during the initiation of flat and cylindrical high-modulus energy sources. The expressions, which establish the relationship between the parameters of flat and hollow cylindrical charges of explosives under the only condition of equality of the developed pressure pulse on the surface of the charge of explosives, provided all other things being equal, were obtained. In contrast to the earlier studies, which assert the existence of a direct relationship between the parameters during the initiation of flat and cylindrical surfaces, the current study demonstrates energy consumption during the initiation of cylindrical surfaces is higher than the initiation of flat surfaces, all other things being equal.
Analysis of the Granulometric Composition of the Feedstock Influence on Mechanical Properties of Iron Ore Pellets
Authors: Bobkov Vladimir I. , Morgunova Elvira V.
Published: February 2022

The paper investigates the effect of high-temperature roasting and cooling modes of roasted iron ore pellets on their strength and porosity. These characteristics depend on the initial iron ore raw materials properties, the parameters of the raw pellets, the firing temperature, the holding time at this temperature, the heating and cooling rate, and take into account the change in these indicators in connection with the chemical and mineralogical compositions of the pellets. It has been established that the strength of iron ore pellets obtained at the optimum firing temperature depends on the characteristics of the initial finely dispersed iron ore raw material. The relationship between the content of draw rock and the strength of calcined pellets has been revealed. A significant influence of the raw pellets porosity on the strength of the calcined pellets was found. It is shown that the crushing strength of pellets cooled in air is higher than the strength of pellets cooled with water, and a decrease in the final cooling temperature leads to an increase in the strength of the pellets. It is substantiated that the heating rate should not exceed the rate of gas diffusion, and with a decrease in the size of finely dispersed iron ore raw materials, the shrinkage of the pellet layer increases during heating. It is shown that shrinkage appears at temperatures lower than the optimal calcining temperature and insignificantly affects the strength of the pellets. The results obtained can be used to substantiate resource-and-energy efficient operating modes of horizontal-grate machines in ferrous metallurgy.
Modeling the Structural Strength of Materials on Disk Laboratory Specimens
Authors: Zenkov Evgeniy , Tsvik Lev
Published: February 2022

The article describes the strength characteristics of the material used for highly loaded structural elements by modeling their stress-strain state (SSS) and testing special laboratory samples for strength. The typical biaxial SSS is characterized by a different ratio of the main stresses in the focus of possible destruction, which affects the strength characteristics and requires the use of special equipment for determining strength values in laboratory conditions. To create a biaxial SSS under these conditions is a difficult task, since it requires non-standard laboratory samples and test systems with several power drives or complex lever devices for loading these samples, which limits the use of this testing method in determining the mechanical properties of materials. The article describes a simpler method for testing materials under complex stress-strain using special laboratory disc samples on standard test equipment with one power drive. The disk sample design and methods of deforming and creating test conditions are described.

The article shows the results of a research in which barium hexaferrite samples of the BaFe11M1O19 (M= Al, Ti and Mn) composition were obtained by solid-state synthesis. Samples substituted with titanium, aluminum, and manganese were obtained in a tubular furnace at an exposure time of 5 hours at a temperature of 1350°C, the sample, substituted with manganese, it was obtained at a temperature of 1250°C. The chemical composition was controlled using electron microscopy the samples obtained correspond to the initial composition with sufficient accuracy. Hexagonal plates represent the structure of all the obtained samples. According to X-ray phase analysis, all samples are monophasic and have the structure of barium hexaferrite. Using the data of powder X-rays, the parameters of the unit cell of the studied samples were calculated, when iron atoms are substituted by titanium or aluminum or manganese atoms, the crystal lattice is distorted, while its change is not the same for different crystallographic directions. During the doping of barium hexaferrite with titanium, aluminum or manganese atoms, the Curie temperature decreases. This is due to a decrease in the exchange interaction forces during the modification of the barium hexaferrite matrix.
The aim of this study was to study the structure and change of the lattice parameters, the Curie temperature, depending on the substitution element.

How the Chemistry of Raw Materials Affects Aluminum Produced in Cells with Prebaked Anodes
Authors: Nemchinova Nina V. , Lazko Aleksandr Yu.
Published: February 2022

This paper analyzes how major impurities found in raw materials affect the chemistry of primary aluminum. Alumina and prebaked anodes tend towards lower quality due to the depletion of natural sources of high-quality bauxites and using low-quality carbon to make prebaked anodes (PA). The authors analyzed the chemistry of raw materials supplied for electrolysis. The paper shows the investigated upward trends in the presence of Fe and Si impurities in alumina and prebaked anodes, which jeopardizes the aluminum production process. The increased presence of such materials worsens the chemical composition of the resulting liquid aluminum. If the finished product is to be of high quality, alumina and PA mast contain, respectively (wt.%): 0.010 and 0.024 Fe, 0.013 and 0.022 Si. The proposed idea is to categorize the alumina in storage. Alumina from different manufacturers must then be batched in such a way as to have consistent, ‘averaged’ chemistry before going to electrolysis cells.
