Published: August 2021

On the example of development a unique on-board gasification system for non-produced residues of liquid fuel in the tanks of the launch vehicle stage, the improvement of the quality of theoretical and experimental research is considered. Due to the uniqueness of the developed on-board gasification system, which begins functioning after the main liquid rocket engine (LRE) is turned off, there are no studies of the proposed method of gasification (evaporation) based on the supply of a carrier heat in the form of hot gas to the tank with liquid fuel residues, and the methodology for selecting the design -engineering parameters of the on-board gasification system. It is obvious that the creation of a methodology for selecting the design -engineering parameters of the on-board gasification system, the further development of the on-board gasification system and the study of its functioning to improve the quality is impossible without conducting a study of the convective gasification process in the fuel tank. To develop a physical and mathematical model and a physical model of the gasification process, an experimental model installation with a model liquid as part of an experimental stand is considered.
THE STANDARDIZATION OF QUQLITY ASSESMENT OF SPECIAL METALLURGICAL CRANES BASED ON DESIGN RISK ANALYSIS
Authors:   Nosov Magnitogorsk State Technical University, Izvekov Yu.A.
Published: August 2021

The article critically analyzes the standards for assessing the quality of the supporting structures of special bridge metallurgical cranes. At the present stage, more than 80% of such cranes are operated outside the warranty period. The standards are aimed either at a finite number of operating cycles, or at objects of low complexity, in particular FMEA. To estimate the resource, the characteristic number, a generalized indicator of the supporting structure, is used. Risk analysis is a promising and recommended one today. The structural risk analysis is considered as an integral indicator for assessing the quality of the actual technical condition of a special metallurgical crane. The article is a continuation of a series on the study of the use of structural risk analysis for assessing the quality of structures of a metallurgical enterprise. Models of quality are given according to the following risk criteria: normal, maximum permissible, critical (catastrophic). The largest catastrophic events of a metallurgical enterprise have been studied for 70 years. The statement of the problem is formulated as follows: it is necessary to critically assess the current state of the standards and find their joint optimal parameters or put forward new requirements to create a draft of a new standard for assessing the quality of special metallurgical cranes operating outside the warranty period. An algorithm is presented that includes and refines modern standards, including FMEA. Quality is calculated as a function that changes over time, inversely proportional to the risk, taking into account the damage. The calculated values of the quality are obtained, which make it possible to relate the number of worked cycles, the acting stresses and deformations.

Published: August 2021

The article proposes a qualimetric method for assessing the quality of such hazardous production facilities of a metallurgical enterprise as special bridge metallurgical cranes. The supporting structure of the crane is investigated, structurally divided into four main groups of structures and fifteen elements, which carry all the information about the dominant properties of the operation of the crane. Two indicators of the quality of the crane structure were introduced: complex and integral. For a complex function, the probability density function of the reliability levels of structural elements in the form of a uniform law is taken. For integral - an indicator of the risk of an accident, since most of the cranes under consideration are operated outside the warranty period. The obtained quantitative data on the reliability levels that structural elements should have is valuable. The investigated qualimetric method will allow experts to make the right scientific and technical decisions and, ultimately, will bring a significant economic effect that can be comparable to the price of a new crane and its commissioning. Special cranes of the Magnitogorsk Metallurgical Combine were considered. The article continues to develop studies of qualimetric science for assessing the quality of products and various objects of a metallurgical enterprise of the scientific school of the Magnitogorsk State Technical University named after V.I. G.I. Nosov.

ANALYSIS OF DYNAMIC PROCESSES IN NANOELECTRONIC STRUCTURES BASED ON MEMRESISTIVE ELEMENTS
Authors:   Orenburg State University (Kumertau branch), Bondarev A.V. , Efanov V.N. ,   Ufa State Aviation Technical University
Published: August 2021

The emergence of recently a wide range of nanoelectronic components is expanding the possibilities of information and computing systems. First of all, it concerns supercomputers with Petaflopovaya productivity. To achieve such performance on the basis of modern microelectronic devices, computing complexes are created, combining up to 100 thousand processors that consume about 100 megawatts of electrical energy and occupy about 300 square meters. A significant increase in productivity, reduction of energy consumption and a decrease in mass-dimensional indicators can be ensured in the transition from microelectronic to a nanoelectronic element base. For such promising nanoelectronic components include memristors. A memristor (from memory — memory, and resistor-electrical resistance) is a passive element in microelectronics that can change its resistance depending on the charge flowing through it. For a long time, the memristor was considered a theoretical model [7], which cannot be implemented in practice, until the first sample of the element demonstrating the properties of the memristor was created in 2008 by a team of scientists led by R. S. Williams in the research laboratory of Hewlett-Packard. The device does not store charge like a capacitor, does not support magnetic flux like an inductor. The change in the properties of the device is provided by chemical reactions in a thin two-layer film of titanium dioxide (5 nm). One layer of the device film is slightly depleted of oxygen and oxygen vacancies migrate between the layers when the voltage changes. This implementation of the memristor belongs to the class of nanoion devices. The observed phenomenon of hysteresis in the memristor allows it to be used, among other things, as a memory cell [9, 10-15, 20-21]. The already studied properties of memristors allow us to say that on their basis it is possible to create computers of a fundamentally new architecture, significantly exceeding semiconductor ones in performance. Due to the regular structure of intersecting nanowires, memristor fabrication is quite simple, especially in comparison with the complex structure of modern processors based on CMOS technology. As a result, the write / read time in the memristor memory cell does not exceed 5 ns. The number of read / write cycles exceeds 1012, and the storage time of information is more than 10 years. All this suggests that memristor memory will become the only type of computer memory. However, the use of such elements in real-life conditions leads to the fact that the electrical parameters of these devices vary over a wide range. This uncertainty in characteristics complicates circuit analysis and the entire design process for electronic devices that include memristor components. In this regard, the problem of assessing the stability of nanoelectronic structures based on memresistive elements under conditions of uncertain external influences is urgent.

Yet several decades ago the term “industrial heritage” was unknown not only to ordinary people, but also to many scientists. However, the transition from an industrial society to a postindustrial one arouses interest in the objects of the former industrial territories. Over the past twenty years, a number of interesting theoretical and applied studies of the industrial heritage of old industrial regions have been formed. These studies raise the problems of the industrial heritage of Russia and its regions, reveal the potential of territories of cultural and historical significance, describe infrastructural complexes and industrial objects of the past. The article describes the role of scholars from one of the main industrial regions of Russia, the Urals, in the popularization of the industrial heritage through theoretical and empirical research. Primary attention is paid to the analysis of the main directions of this activity, presented in publications by various representatives of the scientific community, which form the scientific and cultural background of the topic of preserving the industrial heritage of Russia. There is a large scientific community in Yekaterinburg, represented by many scholars, including Professor V.V. Zapariy, national representative of Russia in TICCIH (the International Committee for the Conservation of the Industrial Heritage), writing on this topic, which is relevant for the industrial region.

The paper presents the results of the Algay site study undertaken in 2020 in the steppe Volga region (Aleksandorovo-Gaisky district of the Saratov region) on the right bank of the Bolshoy Uzen river. During the excavations archaeologists discovered three cultural layers, separated from each other by sterile layers. The upper layer contains finds belonged to the Khvalynskaya Eneolithic culture, the middle layer contains finds from the Caspian one, and the lower layer - from the Orlovskaya culture. The ceramics are made of silty clay with an admixture of mollusk shells. The stone tools differ in raw materials: the Khvalynskaya and Caspian artifacts are made mainly of quartzite, and the Orlovskaya ones are made of flint. The range of objects is dominated by various types of scrapers, knives and cutting points. The flat-bottomed vessels of the Orlovskaya culture are ornamented using the technique of a receding lines with oval and triangular pricks. Patterns are represented by horizontal rows and zigzags. Aurochs, tarpan, saiga and onager were identified among the bones of animals. Bones of a domestic dog were found in the Orlovskaya culture layer, and bones of sheep and goats in the Caspian layer. The bone tools and a shell pendant were also found. The radiocarbon dates indicate the existence of the Caspian layer in the V millennium BC, and the Orlovskaya layer in the VII -VI millennium BC.

The settlement Barsova Gora II/42 is located in Khanty-Mansiysk Autonomous Okrug-Yugra, 15 km west of Surgut, on the high bank of the Ob' River. The settlement is being actively destroyed due to the activities of oil companies. More than 20 objects and structures were investigated in 2011 during rescue excavations, some of them are pits of ancient dwellings (sites 1, 2, 6, 15, 19), some are household outbuildings and pits (sites 3, 4, 7, 8, 9, 10, 11, 13, 14, 16, 17, 18, 20), two objects have a cult purpose (sites 5, 12). An important feature of the monument is that archaeological structures of different epochs and cultures overlap each other, allowing us to trace the sequence of settlement of this part of the Ob River bank. During the Neolithic Age the constructions of Bystrinsky and Barsovogorsky cultural types were located here, the cultural layers containing ceramics of Vakhovsky type belong to the Eneolithic Age, and the constructions and household pits of Kulugansky type belong to the Bronze Age. An ochre storage pit and a ring ochre structure represent a unique object, which is probably related to ancient rituals. The revealed objects (Nos. 15, 19, 18, 2, 1, 5, 17, 13) are partially investigated and require further excavations.

Authors:   Research Center for the Preservation of Cultural Heritage, Saratov, Yudin A.I.
Published: August 2021

The paper contains an analysis of the ceramic collection of the bronze age sanctuary Malaya Sopka. The sanctuary is located in the Oktyabrsky district of the Rostov region and was investigated in 2017. A little more than 10,000 square meters of the cultural layer of the сentral part of the monument were studied, which is about two-thirds of the total area. On the entire territory of the excavation, there were no dwellings, buildings, household pits, and hearths. However, 10 religious complexes were studied on the site, in the form of a system of ditches of various configurations (ring, rectangular, double ring), 12 objects (stone slabs and layouts, ruins of vessels), which gave reason to call Malaya Sopka a place of worship or a sanctuary. The weakly saturated cultural layer contained tools and products made of stone, bone and bronze. The main part of the finds is represented by ruins and fragments of bronze age ceramics and fragments of cattle bones. The ceramic complex of the site was formed at the turn of the middle and late Bronze age at the base of two different cultural traditions: the local Babino (multi-ribbed) and the newcomer Don-Volga Abashevo culture. The syncretic ceramic complex marks the stage of formation of the early Srubnaya (Timber-grave) culture and supplements the data on the cultural genesis of the middle-late Bronze age with the materials of the cult site.

JULIUS LUPUS: TRIBUNE OR CENTURION?
Authors:   Moscow City University, Samara Branch, Guskov E.A.
Published: August 2021

The assassination of Emperor Gaius (Caligula) in January 41 was the prologue to events unprecedented in the history of the Principate. For two days, Rome, seized with the idea of restoring the republic, was under the control of the consuls, the Senate, and the officers of the Praetorian Guard. By the decision of Cassius Chaerea, who was the head of the conspirators, the members of the emperor's family – his widow Caesonia and their daughter – were also killed. The executor of this order was one of the Praetorian officers, Julius Lupus, whom Josephus calls a tribune, but Suetonius calls him a centurion. This article is devoted to this contradiction and its causes.

Varronia curassavica has anti-inflammatory properties because of the terpenes, α-humulene and β-caryophyllene, present in the essential oil. The objective of this study was to evaluate the influence of seasonality on the essential oil of V. curassavica accessions. Leaves from six accessions were collected from the Germplasm Bank of the Federal University of Minas Gerais over 12 months. Correlations between the essential oil content and meteorological factors were determined. Gas chromatography analysis coupled with mass spectrometry was conducted to determine the chemical composition of the essential oil. The content and chemical composition of the oil varied throughout the year. Relative humidity was correlated with accessions ICA-VC2 (-0.64) and ICA-VC4 (0.68). β-bourbonene, β-elemene, spathulenol, germacrene, caryophyllene oxide, α-humulene, and β-caryophyllene occurred in all accessions. Accession ICA-VC3 exhibited lower variation (22.17%), higher average (0.97%) essential oil, and maintained an average abundance of α-humulene greater than 2.6%, which is the amount necessary for phytotherapeutics.

Authors: ŞENER Gülden Ezgi , KANA Fatih
Published: August 2021

Ortaokul öğrencilerinin bilgilendirici metin üretme konusunda yaşadıkları sıkıntıların bilgilendirici metin yapılarını bilmediklerinden kaynaklandığını düşünülmektedir. Bu amaç doğrultusunda metnin yapısal özelliklerinin öğretiminin metin üretme sürecine katkı sağlayacağı varsayılmaktadır. Bu çalışmada, geliştirilen uygulamalar sayesinde ortaokul öğrencilerinin bilgilendirici metinlerin yapısal özelliklerini, metin yazma sürecinde kullanma durumlarını belirlemek amaçlanmıştır. Bu amaç doğrultusunda çalışmada öğrencilerin yazma uygulamaları öncesindeki yazmaya karşı ön algıları ve yaşadıkları yazma sorunları, yazma uygulamaları sürecinde yazma becerilerindeki değişim, yazma uygulamalarından sonra giriş bölümü yazma tekniklerini ve metinlerarası bağlantı kurma tekniklerini kullanma durumları, yazmaya karşı uygulamalar sonrası algıları, ön algı ve son algılarındaki değişim araştırılmıştır. Çalışmada, nitel araştırma desenlerinden ‘Eylem Araştırması’ deseni kullanılmıştır. Çalışma yazma sorunları için geliştirilen uygulamaların sorunları çözüp çözmediğini görme üzerine temellendirildiği için araştırma deseni bu çalışmaya uygundur. Araştırmanın çalışma grubunu, İstanbul İli İl Milli Eğitim Müdürlüğüne bağlı Küçükçekmece ilçesinde bir eğitim kurumunun 7. sınıfına devam eden 44 öğrenci oluşturmaktadır. Çalışmada, öğrenci yazılı anlatım kâğıtları, Ön Algı Açık Uçlu Öğrenci Anketi, Son Algı Açık Uçlu Öğrenci Anketi, Bilgilendirici Metin Yazma Becerisi Analitik Değerlendirme Ölçeği, Giriş Bölümü Yazma Teknikleri Değerlendirme Formu olmak üzere 6 veri toplama aracı kullanılmıştır. Araştırmada veriler, kodlamalar ve temalar aracılığıyla anlamlı hale getirilerek nitel verilerin çözümlenmesinde betimsel analiz uygulanmıştır. Çalışmada, veri toplama araçlarıyla toplanan verilere göre, öğrencilerin yazma uygulamaları öncesi yazma isteği ile ilgili algılarının olumlu olduğu ancak bilgilendirici metin üretiminde yapısal özellikler bakımından algılarının olumsuz olduğu sonucuna varılmıştır. Yazma uygulamaları öncesinde elde edilen ilk bulgudan hareketle yazma uygulamaları yapılmış ve öğrencilerin yapısal özellikleri yazma üretimlerinde genel olarak uyguladığı tespit edilmiştir. Giriş bölümü yazma tekniklerini ve metinlerarası bağlantı kurma tekniklerini kullanma durumlarında da olumlu yönde değişim olduğu belirlenmiştir. Son algı sorularına verdikleri cevaplardan hareketle, öğrencilerin bilgilendirici metin üretimlerinde yapısal özelliklerle ilgili algılarının olumlu yönde değiştiği gözlemlenmiştir.

BACKGROUND & OBJECTIVE: Nonverbal communication has been overlooked in medical education. The purpose of this study was to explore student-teacher perceptions regarding impact of nonverbal behavior of medical educators on educational environment.

METHODOLOGY: A qualitative exploratory study was conducted among purposively chosen final year students (n=150) and medical teachers (n=73) from three dental colleges of Islamabad. A web-based survey concerning three domains of kinesics (Facial expressions, Gestures, Head movement and postures) was developed and validated before execution. Comparison of participant’s responses to closed-ended questions was done by applying Fisher’s Exact Test and open-ended questions were thematically analyzed.

RESULTS: Response rate of students and teachers was 46% and 63% respectively. Five out of nine closed-ended questions gave statistically significant difference among student’s and teacher’s responses (p≤0.05). Twenty-seven subthemes emerged from three domains of kinesics. Students revealed that happy mood of their teachers reduces boredom in the classroom and a teacher’s smile lets them freely express anything, whereas anger produces fear among them. According to the educators a happy instructor inspires students to study and makes the environment friendly and an undemanding smile helps build a rapport with students. Moreover, positive gestures used by teachers encourage students to clarify concepts and upright posture brings energy and motivation to the classroom.

CONCLUSION: A teacher’s nonverbal behavior has a profound effect on educational environment. A smile on a teacher’s face creates a friendly and fearless environment whereas anger creates barriers to communication. A happy teacher can generate a pleasant and motivating learning environment.

Untreated or undiagnosed frontal sinusitis develops as a subperiosteal abscess in the frontal bone named Pott’s puffy tumor (PPT). Pott’s puffy tumor is a rare complication that needs surgical excision. In this communication, we report a 50-year-old woman presenting with typical signs and symptoms of PPT. CT-Scan and X-ray imaging are the gold standards to measure the extent of tumor and involvement of structures, if any.

The worldwide healthcare response to combat severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2, COVID-19) has led to the developments of several highly specialized techniques for diagnosis, for example, whole genome sequencing and computed tomography imaging. Considerable effort is also being directed towards detecting and preventing different modes of community transmission. One such mode of transmission, the presence of the virus on various surfaces that people may come in contact with, is being countered with the rapid detection. To this end, non-contact, optical techniques-based detection of COVID-19 have been shown to be useful for early prevention of spread of the virus by identifying infected surfaces. Especially, researchers have demonstrated nanomaterials-enabled diagnostic methods for rapid and early detection of SARS-CoV-2. It is believed that nanotechnology-based innovations particularly in the fields of diagnostics and therapeutics can provide solutions to the very complex problems of COVID-19 pandemic. Here, we present a critical overview of recent literature that specifically addresses how nano-engineered materials are enabling the effective and rapid diagnosis of COVD-19. Prominent techniques are described that show high accuracy of detection even in trace concentrations, which is achieved by measuring color change and also light-sensitive nanomaterials. Fingerprint techniques that enable identification of virus that is present at the surface are also described. Finally, we present a brief perspective of using nanomaterials in diagnostics, monitoring and surveillance to battle against highly contagious viruses in order to mitigate and prevent future global health emergencies.

Introducere. Istoria utilizării sărurilor de Litiu în medicină a început în anii 1850 prin utilizarea acestuia pentru tratarea gutei. Cum mania şi melancolia au fost incluse în grupul aceloraşi diagnostice, Litiul a început să fie folosit şi în afecţiunile psihiatrice. La ora actuală, Litiul este încă folosit în tulburarea afectivă bipolară şi ca medicaţie adjuvantă în depresie, schizofrenie şi în tulburările schizo-afective, dar şi în controlul agresivităţii infantile. Metode şi obiective. Prezentarea unui caz de intoxicaţie cu Litiu la un pacient cu infecţie bacteriană şi tratament cronic cu litiu. Obiective. Raportarea unui caz de intoxicaţie cu Litiu în context de angină eritemato-pultacee la un pacient în tratament cronic cu Carbonat de Litiu pentru episoade depresive cu elemete psihotice. Concluzii. În practica medicală, intoxicaţia cu săruri de Litiu este rară în contextul folosirii înalt selective şi a dozării stricte a nivelului plasmatic al Litiului. În cazul prezentat aici, infecţia bacteriană activă (angină pultacee) însoţită de febră, incapacitatea pacientului de a se hidrata adecvat şi uşoara insuficienţă renală pe care a prezentat-o în contextul septic, a fost un trigger al mecanismului patogenic al intoxicaţiei cu Litiu la acest pacient. Secundar insuficienţei renale, excreţia Litiului a fost deficitară, iar secundar sindromului de deshidratare, valoarea serică a Litiului a crescut şi mai mult prin scăderea volumului intravascular. În evoluţie, apariţia tulburărilor gastrointestinale au contribuit la cercul vicios între aportul hidroelectrolitic, excreţie şi litemie renală.

Protein-losing enteropathy (PLE) represents an abnormal protein loss at the level of the digestive tract mucosa, being in most of the cases secondary to other gastrointestinal or extraintestinal pathologies. Nevertheless, there also are primary causes, genetic ones associated with PLE. We present the case of a small female child, 1 year and 1 month-old, with a history of infectious enterocolitis determined by Escherichia coli enteropathogenic, who presented palpebral edemas, especially in the morning for approximately 1 week. The laboratory tests revealed hypoalbuminemia, type A and G hypogammaglobulinemia, leukocytosis with eosinophilia, and anemia. The test for the detection of occult hemorrhages from feces was positive, likewise the fecal calprotectin and level of alpha-1 antitrypsin. We identified also allergy to cow’s milk protein, which we interpreted as being secondary to the intestinal pathology. Thus, we established the diagnosis of protein losing enteropathy after an episode of acute enterocolitis caused by E. coli enteropathogenic, and we administered substitutive treatment with human albumin and steroids, with favorable evolution. The particularity of the case consists in diagnosing a severe case of protein-losing enteropathy in a small child, with palpebral edema, predominantly during the morning, and decreased levels of serum albumin, after an episode of acute enterocolitis caused by E. coli enteropathogenic, which remitted without etiologic treatment.

Infectious diseases have accompanied human development from the earliest times and have often influenced it greatly. Although they were considered “an endangered species” in the second half of the 20th century, they continue to pose a serious threat to individual or public health. Diagnosis technique improvement, climate changes, increased population mobility and vaccine cover decrease are only some of the factors that have contributed lately to the occurrence and fast spreading of new pathogens or to the re-emerging of diseases already considered historical. Most of these infectious agents (Zika, Ebola, Chikungunya, MERS, SARS, new influenza viruses), for which there are few therapeutic resources, were the cause for regional or global epidemic outbreaks, which generated concern among healthcare professionals and often panic in the population, as well as significant economic losses. The international and medical communities joined their forces and got financially and logistically involved, sometimes paying with their own lives, in fighting these new threats. The fast understanding of the epidemiological process, pathogenesis and development of diagnosis and prevention methods has often helped limit the spread of emerging diseases and has laid the grounds for their future control.
