Authors: Cizek Jan , Musalek Radek , Medricky Jan , Tesar Tomas , Lukac Frantisek , Chraska Tomas , Dukovsky Daniel
Published: September 2021

In suspension spraying, the two most frequently used solvents are water and ethanol. In this study, we test a potential alternative, a high-molecular weight solvent. Two organic solvents are compared: ethanol (serving as a benchmark, suspension formulated at 10 wt.% solid load) and di-propylene glycol methyl ether (two suspensions at 10 wt.% and 20 wt.%). Submicron alpha-alumina powder is used as a model material to formulate the suspensions. It is shown that ethanol- and ether-based-feedstock coatings are fully comparable in terms of their microstructure, porosity content, surface roughness, and hardness. However, the ether-based coatings exhibit slightly higher levels of α-Al2O3 phase than their ethanol-based counterpart (17 wt.% vs. 6 wt.%). The use of 20 wt.% solid load in the ether solvent leads to a twofold increase in the deposition rate while, as opposed to ethanol, successfully retaining a dense microstructure. Ether also costs less than ethanol and is safer to handle.

Published: September 2021

Cold Gas Spray (CGS) technology has allowed the development of biofunctional composite coatings composed of 45S5 and Polyetheretherketone (PEEK). The combination of a bioactive glass material embedded in a biocompatible polymeric matrix becomes this new composite in an interesting material for orthopedic applications since meet the biomechanical and biological requirements of an artificial implant. In the present study, blends of bioactive glass 45S5 and PEEK powder with different granulometry and 45S5/PEEK ratio have been prepared. These mixtures of powders have been deposited onto PEEK substrates by CGS with the goal of incorporating a bioactive additive to the biocompatible polymer, which can improve the bone-implant interaction of PEEK. The deposition efficiency (DE) and thickness of the coatings have been evaluated and from the results obtained, it was possible to conclude that DE and coating thickness are significantly affected by the granulometry and by the 45S5/PEEK ratio of the blends. By Scanning Electron Microscopy (SEM) inspection, it was observed that the use of blends with high 45S5/PEEK ratio led to the deposition of coatings with high content of 45S5 particles embedded in the polymeric matrix. Finally, the friction behavior of the coatings was analyzed performing ball-on-disk tests and these experiments showed that the presence of glass particles has a beneficial role in the wear resistance of the coatings.

Authors: Pocquette Nicholas , Yeom Hwasung , Agiwal Hemant , Pfefferkorn Frank , Sridharan Kumar , Ross Kenneth , Kessler John , Cannel Gary
Published: September 2021

Cold spray deposition is being investigated for mitigation of chloride-induced stress corrosion cracking (CISCC) in dry cask storage systems (DCSS) for spent nuclear fuel. Welded regions of austenitic stainless-steel canisters in DCSS are under tensile stress and susceptible to environmental chloride corrosion, which can potentially lead to the formation of CISCC. The low thermal input and high throughput nature of cold spraying make it a viable repair and mitigation option for managing potential CISCC. Cold spray coatings are under compressive stress and act as a barrier in Cl-rich environments. Characterization data including microstructure, hardness, and corrosion resistance are presented for cold spray coatings on stainless steel substrates.

Authors: Yao Yijun , Liu Shaowu , Planche Marie-Pierre , Deng Sihao , Liao Hanlin
Published: September 2021

In thermal spray processes, the characteristics of in-flight particles (velocity and temperature) have a significant effect on coating performance. Although many imaging systems and algorithms have been developed for identifying and tracking in-flight particles, most are limited in terms of accuracy. One key to solving the tracking problem is to get an algorithm that can distinguish different particles in each image frame. As the study showed, when noise and interference are treated, particles are more readily identified in the background, leading to more accurate size and position measurements with respect to time. This approach is demonstrated and the results discussed.

Authors: Aissou Taki , Veilleux Jocelyn , Braidy Nadi
Published: September 2021

Recent studies have shown that graphene can improve the tribological performance of materials by lowering the coefficient of friction and increasing wear resistance. In this present work, the authors evaluate an inductively coupled plasma process that synthesizes graphene nanoflakes in-flight and uniformly deposits them on metallic substrates. The quality of the graphene flakes was characterized and coating surface friction was measured using a ball-on-three-plates tribometer. Test results showed that graphene nanoflake coatings reduced the coefficient of friction of steel from 0.6 to less than 0.2.

Published: September 2021

Plasma spraying was used to deposit Li3PO4 coatings from sintered dense powders in three size ranges to study the effects of particle size and spraying distance. Coating microstructure, crystal structure, and composition were characterized using SEM, XRD, ICP-MS, and FTIR. It was found that sintered dense powders have a high temperature orthorhombic phase (γ-Li3PO4) that differs from the β-Li3PO4 phase associated with agglomerated Li3PO4. Plasma-sprayed coatings produced from these powders have similarly dense microstructures with fracture-surface morphology like that of sintered bulk. The effect of particle size and spraying distance on atomic ratio is also investigated in the study.

Authors: Dehaghani Shahed Taghian , McDonald André , Dolatabadi Ali
Published: September 2021

Developing effective heating systems to prevent ice accretion on the surface of wind turbine blades and aircraft wings is of great significance for extreme cold environments. However, due to high velocity impingement of water droplets and solid particles on the surface of these components, an appreciable degree of surface material degradation may occur. In this study, nickel-chromium-aluminum-yttrium (NiCrAlY) was chosen as a metal matrix material for a coating-based heating system. Pure ceramic powders, namely, alumina and titania, and a cermet powder, tungsten carbide-cobalt (WC-12Co), were mechanically admixed with NiCrAlY powder and deposited to fabricate reinforced metal matrix composite (MMC) coatings. The powders were deposited on cylindrical low carbon steel bars by using flame spraying. The specimens were placed in a wind tunnel to conduct a comparative investigation of their erosive wear resistance under water droplet impact. A cold spraying unit was used for solid particle impact erosion tests. The erosive wear rates were quantified by measuring mass loss. The experimentally obtained results showed noticeably lower wear rate in NiCrAlY-WC-12Co and NiCrAlY-titania coatings compared to the other coatings. The results suggest that certain MMC coatings could be effectively employed to decrease the erosion rate of coating-based heating elements.

Aim: This retrospective analysis of the GFR values of the individual moieties obtained by using a novel software with modified GATE’S formula in the in house software created at SSSIHL, compared and evaluated with the value derived by the combined GFR value of the single kidney GFR as obtained from the Icon software loaded in the gamma camera. Materials and Method: This retrospective study of 10patients diagnosed with unilateral double moiety and 5 patients with bilateral duplication was undertaken to validate the modified GATE’S formula in house software created at SSSIHL. This group had 12 males in the age range of 03-66 years with the mean age of 26.5 ± 2 years and 3 females in the age range of 29 – 31 years with mean age of 31 ± 2 years. Renal scans were done using Siemens dual head gamma camera (E.CAM). The radiopharmaceutical 99mTc-DTPA 5 mCi was injected as a bolus intravenously for the adult patients and 3 mCi was injected for the children. The images were obtained and processed by using GFR/Renal differential processing protocol in icon software. Later the raw data of the scan study transferred to the workstation loaded with the in house software created at SSSIHL with modified GATE’S formula created by us. The individual moiety GFR values were calculated using the software with modified Gate’s formula developed in MATLAB GUI algorithm and tabulated. Then the combined value of individual moiety GFR values compared with that of the individual whole kidney GFR value obtained by the Icon software protocol. Result: The T test evaluation done in the online statistical calculator of Maths Portal org revealed that the mean values of the two groups showed no significant difference at p < 0.05. The calculated t value is smaller than the critical value (0.0217 < 2.024), so the means are not significantly different.

Published: September 2021

From medical point of view, “Diarrhea” is an alteration in a normal bowel movement characterized by an increase in the water content, volume, or frequency of stools. Acute diarrhea of infec­tious etiology, often referred to as gastroenteri­tis and is typically associated with clinical signs and symptoms including: nausea, vomiting, abdomi­nal pain and cramps, bloating, flatulence, fever, passage of bloody stools, tenesmus, and fecal ur­gency. Infectious diarrheal diseases are the second leading cause of morbidity and mortality worldwide. It is the diarrhea we have also found out, during a large 3 yeas study 2017-2020 in Transylvania – Romania. 3577 number of cases were transmitted during this time, to our Public Health Center, by 12 district Sanitary Polices. These were mostly diagnosed by the territorial family doctors and more than 50%, have need hospitalization, for several days because of the mentioned disease disorders. The detected infectious etiology, were determined in authorized laboratories in which it was identified: Shigella, Salmonella, Campylobacter, and Yersinia, Rotavirus, Giardia. Most number of cases appeared in children, followed by elderly or adult people, as quantified number of determination. In light of these data, acute diarrheal illness had to be considered a major public health issue against which control efforts are needed. Public health surveillance and response in the field of infectious acute diarrhea include obligatory strategies of infection control.
Caffeine and blood flow
Authors: Merrill Gary
Published: September 2021

Arguably, caffeine is the world’s leading drug of choice. It is estimated that in the U.S. and Europe at least ninety per cent of the adult populations consume caffeine-containing beverages several times each day. It is also known that consumers prefer their hot coffee to be in the range of 45-60°C (i.e. as hot as 140°F). If such a drink is spilled on the exposed skin it can cause full-thickness, third degree burns within 5 seconds. These are the kinds of burns that produce permanent damage and scarring for life. The prudence of consuming hot coffee and other hot drinks at such temperatures is questionable, especially when children and adolescents are involved.

Authors: Mubeen Muhammad
Published: September 2021

The Sufi shrines that emerged and developed in the Indian subcontinent during the medieval period had developed their respective patterns of succession to the office of their custodians based on relation to their separate Sufi orders. The office bearers also enjoyed a level of socio-religious, spiritual, and moral authority according to the status of their shrines in the realm. However, after the emergence of the modern state in the Indian subcontinent, the succession issues at the Sufi shrines became part of the judicial system established by the British. Likewise, the succession issues that emerged at the shrine of Baba Farid in Pakpattan (Punjab-Pakistan) during the colonial and postcolonial times were also dealt with through the new judicial apparatus. The arising phenomenon significantly impacted how issues were handled, affecting the office bearers local spiritual and moral standing. This study intends to explore the nature of the recent succession cases and analyze the effects of the encounter of the office of the sajjada-nishin of the shrine of Baba Farid with the modern state had on its socio-religious stature.

An Analysis of Syrian Conflict with the Lens of the Realist School of Thought
Authors: Ahmad Sohail , Mubeen Muhammad , Kalim Inayat
Published: September 2021

The Syrian war is rooted in the conflict between the Sunni opposition and Shia leader President Bashar, torn the country. The Syrian war took baby steps during the Arab Spring, which was supposed to bring hope and prosperity to Syria but unfortunately led to a series of horrifying protests that grew into a 9-year long civil war. The war-torn country has forced millions to escape the horrors of continuous fighting only to seek refuge in other countries with bare minimum resources. Multiple efforts by the International Organizations (I.Os) to halt the conflict between President Bashar and the opposition have repeatedly failed, and apparently, there is no hope for a peaceful solution. This paper aims to explain the Syrian war and break down the reason behind each ally's support to the chosen party and understand the Syrian conflict through the lens of Realism. The realist theory will shed some light on the root cause of international intervention by world powers and regional powers and how each actor's actions prolonged the conflict in Syria. And finally, to understand how domestic and international politics was used to carry out heinous crimes against innocent Syrian men, women, and children and analyze the strategies of actors to gain power in the region.

Published: September 2021

The article is devoted to the application of economic and mathematical models of business planning management based on the use of the feedback principle. As the objective function (evaluation toolkit) of the task, the value of the execution time of the entire business project, which must be minimized, is considered. To solve this problem, it is proposed to form a class of admissible strategies for optimal adaptive control of the implementation process; as well as a specific business project using network economic and mathematical modeling is worked out. Within the limits of these strategies, the method of achieving optimal self-adjusting control of business planning processes is determined, the optimal execution time and the optimal timetable for the implementation of the project are determined. The main feature of the proposed new method is the ability to take into account the real conditions for the implementation works of the concrete project, which makes it possible to timely adjust the process of management of business planning and prevent disruptions in its implementation. This method also serves as the basis for constructing numerical algorithms for the development and creating the automated systems for realization of optimal adaptive control of business planning processes. The results obtained are illustrated on a specific business project for opening a public catering enterprise and show a high degree of efficiency in using the new method.

HÖLDERLIN WOULD EXPLAIN: THE POETICAL THINKING OF FRIEDRICH HÖLDERLIN AND ITS RECEPTION BY BORIS POPLAVSKY
Authors:   HSE University, Tokarev Dmitry Victorovich ,   Institute of Russian Literature (Pushkinskij Dom), Russian Academy of Sciences
Published: September 2021

The article focuses on the two notions recurrent in Boris Poplavsky’s late-period oeuvre, namely the «Paradise and Kingdom of friends» and the «Republic of the Sun». These are linked to Friedrich Hölderlin’s poetical philosophy, which solicited vivid interest among the German and French poets of the 1910–1930s. It is assumed that the semantic aura of the image of the fl ag, one of the most frequent in Poplavsky, might have been formed in a «dialogue» with Hölderlin’s key poem Hälfte des Lebens. Besides, the poem Quietly the City Rustles, which holds a place of prominence in his posthumous collection Snowy Hour (1936), seems to be an imitation of the fi rst stanza of Hölderlin’s famous elegy Brot und Wein.

In his sermons, Kirill of Turov makes ample use of quotes, allusions and reminiscences. As a rule, he appeals to hymnography, although his Word for Thomas Sunday relates to Gregory of Nazianzus’s sermon for the same holiday. In this text, Kirill of Turov relies on a reader who had just heard the sermon, recited, in compliance with the regulations, on that very day. Thus, without this specifi c background, one would be hard put to understand the Word for Thomas Sunday. The comparison of the two texts offered in the article highlights additional meanings in this work by Kirill of Turov.

Published: September 2021

The article analyzes the function of the epigraph to the story The Firewood, that goes back to one of Blok’s short comic poems. As a part of the story’s semantic structure, the epigraph makes it possible to actualize implicit autobiographical and historical-literary narratives. The mysterious Christmas code offers the key for an interpretation of the work in the context of the moral and ethical evolution of Zoshchenko’s character, which rhymes with that of the writer himself. The article demonstrates the prescience of Blok’s ideas for the existence of an artist in the Soviet sociocultural context throughout the 20th century.

The article considers the types of presentation of the poet’s personality in a unique memorial collage based on the materials from the archive of Remizov’s wife, creatively reworked by the writer. In the work, S. P. Remizova-Dovgello’s references to the name of Blok in her diary entries and in the recordings of her dreams are accompanied by extensive comments by Remizov. Remizov’s evaluation of Blok’s poem The Twelve, that is introduced into scientifi c circulation for the fi rst time, is of particular interest.
A PICTURE BY DOSTOEVSKY AND A PANORAMA BY TOLSTOY: ON THE HISTORY OF A PARALLEL IN THE WORKS BY VYACH. IVANOV AND ANDRÉ GIDE
Authors:   National Research University Higher School of Economics in St. Petersburg, Dimitriev Viktor Mikhalovich ,   Institute of Russian Literature (Pushkinskij Dom), Russian Academy of Sciences
Published: September 2021

The article deals with the pictorial analogy used in V. Ivanov and André Gide’s works on Dosto-evsky. According to the analogy, the artistic technique of Tolstoy can be associated with the diffused light, while the one of Dostoevsky — with the art of chiaroscuro. We are trying to understand if Gide could have been familiar with the work by Ivanov; what historical, literary and art history works could have served as a common source for this analogy, and how the analogy functions in the works by the two authors.
Dostoevsky: A Step into the Third Century (Observing the Inside as Observed from the Outside)

An international language of interethnic communication emerges from Dostoevsky’s novels published in translations. The signifi cance of the pronouncements by various foreign cultural fi gures concerning the Russian writer is determined by the fact that today they shape the public opinion of tomorrow. They focus on Dostoevsky’s relevance for modern life, the universality and accessibility of his work for various periods and cultures. The multifaceted human nature, as refl ected in the works by Dostoevsky, is particularly obvious in the fact that various cultural fi gures see the writer’s various protagonists as the most compatible ones with the spirit of our time. The stage directors’ and moviemakers’ creative dialogue with Dostoevsky does not negate the fact that the value of his own „mes-sage“ is much greater than the aesthetic impact of the works of art he has inspired. The „dispute“ about Tolstoy and Dostoevsky has not been ignored either. According to the art activists of today, Dostoevsky novels help to shape the picture of Russia and the Russian folk. At the same time, though, they offer a true and profound picture of humanity and human nature in general.

«SO AVARICIOUSLY I WANT TO LIVE…»: CONCERNING A POEM BY WANDERER AND THE FLOW OF ROMANCE IN THE LYRICS BY A. A. BLOK
Authors:   Institute of Russian Literature (Pushkinskij Dom), Russian Academy of Sciences, Loshchinskaia Nina Vladimirovna
Published: September 2021

The article discusses the elements of song and Romance in Blok’s lyrics, as well as the problems of establishing specifi c Romance sources of his poems of the 1900–1910s. Using the textual evidence from the poet’s notebook, the author analyzes the transformation of the Romance lyrics by Wanderer, «The Bells are Ringing», in Blok’s cycles The Iambi and Gray Morning, and outlines the connotations of rebellious motifs and images in one of Wanderer’s most popular poems of the 1900s, «I’m Not With You, and Thus in Vain…» in the poems from the The Iambi cycle. The article introduces the academic community to unpublished materials from the archives of Blok and Wanderer.

Published: September 2021

A large amount of Hg is used for gold extraction through the amalgamation process in the Apolobamba gold mining area located in the northwest part of La Paz, Bolivia. This mining operation may produce a very serious impact on the ecosystems, as well as on the health of miners and inhabitants, mainly due to the primitive methods used in the gold recovery. The objective of this work was to characterize the potential contamination of total Hg in soils, sediments, water, and plants in a mining area of Bolivia. Results showed that there was atmospheric deposition of Hg in the study area. Accumulation of this metal in the studied soils and sediments was one of the highest in the world, but Hg in aquatic solution was below the detection limit of the analytical method of the studied lakes and rivers. The highest concentration of Hg was found in the river sediments of the Sunchullí- Viscachani (102 mg kg-1), and in the sediments of Sunchullí and Viscachani lakes (12.3 and 11.7 mg kg-1, respectively). These concentrations may pose a serious problem for aquatic life, related ecosystems and human health. Therefore, there is a need to study Hg availability and speciation in soils and sediments to better understand the cycling of Hg in the area.
Petroduric and 'petrosepiolitic' horizons in soils of Namaqualand, South Africa .
Authors: Francis Michele Louise , Ellis Freddie , V. Fey Martin , Poch Rosa María
Published: September 2021

Indurated, light-coloured 'sepiocrete' horizons have been found in Namaqualand Calcisols and Durisols. These horizons resembled calcrete but were non- to only mildly calcareous, resisted slaking in acid and alkali, and often broke with a conchoidal fracture. The presence of elevated quantities of sepiolite in the bulk-soil was confirmed by XRD analysis. The degree of induration in some these horizons suggested cementation by silica, and so in this paper the slaking properties, bulk chemistry, mineralogy and micromorphology of these horizons are compared with the typical silica-cemented, reddish-brown petroduric/duripan (dorbank) encountered in the region. 'Sepiocrete' horizons are chemically, mineralogically and morphologically distinct from the petrocalcic and petroduric horizons with which they are commonly associated. Micromorphology of the petroduric horizons revealed prominent illuviation in the form of oriented clay parallel to grains and crescent coatings on voids, a red matrix due to iron oxides, and translucent, isotropic amorphous silica coatings on grains and voids. In the 'sepiocrete' horizons, sepiolite appeared as a matrix of interlocking, sub-parallel fibres while the amorphous material was localised. The amorphous material was silica-rich with prominent aluminium and lesser magnesium; light brown under plane polarised light; not completely isotropic and had a lower birefringence than the sepiolite. The calcite was usually micritic, but also appeared as loose granules and as elongate crystals in a sepiolite matrix. The presence of the laminar Si-Al -rich areas on the sections suggested at the least localised duric properties and so mutual reinforcement of sepiolite and silica is possible. However, the 'sepiocrete' horizons did not meet the slaking requirements of the petroduric (dorbank) horizons and are distinct in appearance to the typical petroduric horizons in the region. They contained more MgO than the region’s typical petroduric, and too little SiO2 to be silcrete. While the '-crete' terminology provides a useful expression of the cemented nature of the horizon, in order to fit existing soil classification and description schemes the terms 'sepiolitic' and 'petrosepiolitic' (in the same sense as 'calcic' and 'petrocalcic') are proposed and defined. The term 'sepiolitic' would be useful in the adjectival form in petrocalcic or petroduric horizons where sepiolite is significant but not the primary cement. The genesis of the 'petrosepiolitic' horizons is likely to be essentially similar to that of petrocalcic and petroduric horizons, except for chemical differences in the matrix solutions from which secondary minerals were precipitated, dictated by the pH and evaporative evolution of the soil solution.
