Authors: Yahya Nagham Qadoori , Saloomi Ismail Dawood
Published: December 2022

There has been an increasing recent interest in using JOIN strategy in teaching various aspects of EFL. This study tries to find out the extent to which this strategy can be applied to teaching short stories. It also aims to find out whether or not using this strategy can lead to any progress in developing students' comprehension of short stories. To conduct the study, it is hypothesized that there is no statistically significant differences between the mean scores of the experimental group, which is taught by the JOIN strategy and the control group which is taught by the traditional strategy in the posttest achievement in short stories. To achieve the aim of the study and verify its hypotheses two types of procedures have been following: Theoretical and practical. The theoretical procedures consist of presenting a theoretical framework of JOIN strategy including their characteristics, principles, The practical procedures consist of conducting an experimental which last for fifteen weeks. The total numbers of sample subjects was (75) students: (35) in experimental group and (40) students in the control group. The two groups were exposed to an achievement posttest after ensuring its validity and reliability. Suitable statistical tools have been used to analyses to the results of the study. The results have also shown that there was a significant difference between the mean scores of the experimental group and the control group in favour of the experimental group.

Deception in American Propaganda: A Pragma-Rhetorical Perspective
Authors: Bjaiya al-mas'ud Hameed Hassoon , Naif Abdullah Muhammad
Published: December 2022

This paper is intended to explore deception in American Propaganda. Seemingly, this concept, to the best of the researcher’s knowledge, has not received enough conceptualization as far as rhetorical pragmatics is concerned. This study tackles the problem of the lack of one-to-one correspondence between the speaker's underlying deceptive intention and the utterance offered.The present research has the task of giving an overall insight of the theoretical background with regard to the notions of deception, propaganda and rhetorical pragmatics. It aims to manifest the highly exploited pragma-rhetorical strategies in American propaganda.This work is based on the hypothesises: (1) certain argumentative appeals are more exploited than others in American propaganda, (2) certain pragma-rhetorical tropes are more frequently utilized than others to achieve specific deceptive ends, (3) there are significant differences between American propagandists in employing pragma-rhetorical strategies and (4) all the pragma-rhetorical strategies are exploited by both propagandists.The data of analysis include two American propagandistic political interviews. These are qualitatively (pragma-rhetorical) and quantitatively (statistical) analysed. The findings prove the validity of the hypothesises: (1), (2) and (3) while (4) is rejected.
Traditional House-Yard Complex in the Historical Settlements of the Terskoye Pomorye (Based on the Materials of Expeditions to the Village of Varzuga)
Authors: Usov Aleksei Aleksandrovich
Published: December 2022

The article presents the preliminary results of the architectural and ethnographic survey of the Varzuga settlement. The subject of the study is the traditional complex-houses in the cultural landscape of the rural historical settlements of the Terskoye Pomorye. The purpose is to determine the place and role of the house in the space of a modern Pomorye settlement; to identify the architectural and structural features, layout and decor of the dwelling as an ethnomarker of Russians in the North and the Arctic. The research is based on empirical material obtained during expedition survey in 2022 in the Tersky district of the Murmansk region. Also, it is based on the application of the author's methodology of the Doctor of Sciences (Culturology) A.B. Permilovskaya on architectural and ethnographic survey of wooden architecture objects. The author concludes that the Varzuga dwelling is a more compact version of the “brus” (beam), which is found in the settlements of the southern coast of the White Sea. The main constructive difference is that the “back” hut here is adjacent not to a cold barn, but to a significantly reduced utility yard, and has its own “main” facade overlooking the back of the house. However, in general, even a significantly rebuilt house retains its place as a factor in the formation of the cultural landscape of the settlement, bears the features of the continuity of ancient carpentry traditions, and in its laconic decor contains cultural meanings that reflect the mentality of the local Pomors population.

Introduction. The analysis of existing methods for determining the estimated time of fire detection by means of fire automatics allows us to conclude that it is advisable to use a more differentiated approach. Within the framework of this article, the assumption about the influence of the distance from the burning plane of the fire seat to the level of installation of fire detectors (to the sensitive elements of point smoke fire detectors) on the estimated time of fire detection was carried out. In particular, such an effect can be observed during a fire involving the burning of furniture, shelving, etc., i.e. in cases where the above distance is potentially shortened. Goals and objectives. The aim of the work is to study the influence of the distance from the burning plane of the fire seat to the level of installation of fire detectors (to the sensitive elements of point smoke detectors) on the estimated time of fire detection. Research methods. To assess the influence of the distance from the burning plane of the fire seat to the level of installation of fire detectors (to the sensitive elements of point smoke fire detectors) on the estimated time of fire detection, computer simulation methods were used using the Fire Dynamics Simulator software package. Results and its discussion. The results of modeling the dynamics of the optical density of smoke in a room at various distances from the burning plane of the fire seat to the level of installation of fire detectors (to the sensitive elements of point smoke fire detectors) are presented. The distance varied in the range from 0.25 to 2.75 m. Conclusions. It has been established that the distance from the burning plane of the fire source to the level of installation of fire detectors (to the sensitive elements of point smoke detectors) does not have a significant effect on the estimated time of fire detection. The difference in the values of the estimated fire detection time for different values of the distance from the burning plane of the fire source to the level of installation of fire detectors and the value obtained on the basis of the existing method for determining the time of the start of evacuation may indicate an unreliable assessment of the total time of the start of evacuation and incorrect conclusions about safe evacuation people and/or the likelihood of people evacuating. To correctly take into account the time of the beginning of the evacuation, further study of this issue and comparison of its "technical" component, obtained by calculation methods, with the results of field experiments is required. Keywords: fire safety, fire protection, fire detection time, fire alarm, evacuation probability, smoke optical density, evacuation time, evacuation start time, fire risk.

Introduction. Fire risk management is an important part of any country's fire safety. For fire risk management, the normative value of individual fire risk (IFR) is important. This indicator allows fire safety specialists to compare the actual (calculated) values of an individual fire risk with its standard value. In many countries of the world, the values of IFR are defined, but in Vietnam such a standard has not yet been established, which complicates management activities in the field of fire safety. To establish the value of IFR, the limiting indicators of this value are initially determined. Aims and Purposes. The purpose of this article is to define an upper and lower limit for individual fire risk. To achieve this goal, it is necessary to develop an algorithm and apply it to determine the limiting values of the IFR. Methods. Used methods of mathematical analysis and methods of mathematical statistics. Results and discussion. Based on the results of the study, an algorithm was obtained for determining the upper and lower limit levels of individual fire risk in Vietnam and their specific values. This is an important step in directly defining the value of the IFR for Vietnam. Creating the value of IFR is extremely necessary when making managerial decisions to ensure the fire safety of territories and objects economically in Vietnam. Conclusions. Based on the developed algorithm, it was found that the indicator of the upper limit level of individual fire risk for Vietnam is 3,7∙10-6 and the indicator of the lower limit level is 3,7∙10-8. This means that the death toll from the fires in Vietnam must be higher than 3,7 deaths per 100 million people. per year and below 3,7 victims. per 1 million people in year. The value of the normative individual fire risk in Vietnam should be within these limits. Keywords: individual fire risk, marginal risk level, null hypothesis, ALARP principle, regression analysis.

Introduction. In order to maintain and restore existing excavated fortification special structures in the state corresponding to combat missions, timely reconstruction and overhaul work is necessary. To select the optimal option for the restoration of such structures, it is necessary to carry out verification calculations of building structures, check the compliance of excavated special fortifications with the required protection class. However, these calculations are performed on the basis of methods based on fundamental solutions developed back in the 80-90s of the last century. At present, the calculation software systems, methods and methods for conducting a survey of the technical condition of load-bearing structures have changed, new technologies, devices and devices, new building materials, etc. have appeared. Targets and goals. Тo study the applied methods for calculating excavated special fortifications. Perform a thorough analysis of existing methods, in order to identify their advantages and disadvantages. Methods. In the process of work, various scientific and methodological sources, departmental regulatory documentation related to the issue of assessing the degree of protection of excavated special fortifications were analyzed. Results and its discussion. It has been established that all the applied calculation methods are used in the design of newly erected fortifications and take into account the normative state of the supporting structures. Their use in the reconstruction of special fortifications is incorrect and leads to significant errors in the results obtained. Conclusion. As a result of the study, it was determined that the increased deformability of the frame structure leads to the need to improve the calculation methods by considering spatial design schemes. To understand the full picture of the operation of load-bearing structures, taking into account defects and damage, it is necessary to consider the behavior of load-bearing structures of KSFS under repeated impacts.

Is clindamycin-modified triple antibiotic paste better than iodoform-based medicament for the treatment of non-vital primary molars using LSTR technique – A randomised clinical trial
Authors: Verma Neetika , Gupta Anil , Garg Shalini , Arya Vishal , Dogra Shikha , Dhankar Monika
Published: December 2022

Objectives:

The objectives of this study were to evaluate and compare the success rate of local application of iodoform-based obturating material (Pulpotec – [Produits Dentaires S.A., Switzerland]) and clindamycin-modified triple antibiotic paste (ClinM-TAP) in pulp chamber using minimally invasive endodontic treatment of carious primary molars indicated for pulpectomy, for 12 months, using clinical and radiographic parameters.

Materials and Methods:

A randomised clinical trial was conducted in 60 children in the age group of 3–8 years reporting carious primary molars with symptoms of irreversible pulpitis and pulpal involvement clinically, allocated into Group 1 (30) and Group 2 (30). In Group 1, Lesion sterilisation and tissue repair (LSTR) was done using Pulpotec (Produits Dentaires S.A., Switzerland) as medicament and in Group 2, ClinM-TAP (Clindamycin-modified triple antibiotic paste) was used as medicament. Clinical follow-up was done at 3, 6 and 12 months; radiographic follow-up was done at 6 and 12 months. Clinical parameters compared were tenderness on percussion, spontaneous pain, intraoral swelling and sinus/fistula. Radiographic comparison was done based on furcation radiolucency, root resorption and bone regeneration. Both intergroup and intragroup statistical analysis was done using Chi-square test or Fisher exact test, Cochran’s Q Test and Mann–Whitney U-Test for the test of significance. All the statistical tests were performed at 5% significance level.

Results:

The mean age of patients in the study was 5.25 ± 1.3years with 45% males and 55% females. Both groups showed significant improvement in terms of clinical symptoms from baseline to 12 months. On intergroup comparison clinical parameters, TOP was present in 11.2% and 44% of cases at the end of 12 months in Groups 1 and 2, respectively (P< 0 0.05). On intergroup comparison of radiographic parameters, at the end of 12 months, furcation radiolucency was seen in 32% and 73% (P< 0.05) and root resorption was seen in 16% and 30% cases in Group 1 and 2, respectively (P> 0.05). Overall clinical success rate of Group 1 and Group 2 was 88% and 50%, respectively (P< 0.05) and radiographic success rate was 60% and 27%, respectively (P< 0.05).

Conclusion:

LSTR using Pulpotec as a medicament has shown promising results in the present study. It could be a better alternative to conventional endodontic treatment in primary teeth. In the present study, ClinM-TAP has shown poor radiographic success; hence, it should be used with caution.

Published: December 2022

Objectives:

Leptadenia hastata(Pers) Decne (Apocynaceae) is a common medicinal plant used in northern Nigeria either singly or together with conventional drugs to treat diabetes. This study investigated the influence of concurrent administration of the methanol leaf extract ofL. hastatawith metformin in streptozotocin/ nicotinamide-induced diabetic rats.

Materials and Methods:

Possible synergistic activity between the extract and metformin was assessed using 3 models of synergy analysis (Loewe additivity, Bliss independent and highest single agent [HSA] models). Eleven groups of Wistar rats (eight animals per group) consisting of ten groups of diabetic rats and one normal control group were used in this study. Six groups were administered with either the extract or metformin at three different doses each (50, 150 and 500 mg/kg for the extract and 30, 100 and 300 mg/kg for metformin), while another three groups were co-administered with the extract and metformin at three different ratios each (50 mg/kg: 30 mg/ kg, 150 mg/kg: 100 mg/kg and 500 mg/kg: 300 mg/kg). An oral glucose tolerance test (OGTT) was conducted at baseline and on day 14.

Result:

The results revealed that the extract-metformin combination brought about a synergistic reduction in the total area under the OGTT curve (based on Loewe and HSA models) as well as a synergistic reduction in blood glucose (based on Loewe, Bliss and HSA models).

Conclusion:

The methanol leaf extract ofL. hastataproduced a synergistic antidiabetic activity in streptozotocin/ nicotinamide-induced diabetic rats when combined with metformin.

Published: December 2022

Giant cell tumors (GCTs) of the skull are rare and only a few case series with limited number of cases have been reported till date. In the cranium, GCT usually occurs in the sphenoid and temporal bone, occipital condyle GCTs are very rare. We report a rare presentation of GCT of the occipital condyle manifested as occipital condyle syndrome. Despite gross total resection, they can recur aggressively; the presence of cortical breach might be an indicator of aggressiveness prompting early post-operative imaging and adjuvant therapy.

Authors: Kashyap Manshi , Kashyap Priyanka Vikas
Published: December 2022

Lyme disease is a tick-borne infectious disease caused by Borrelia burgdorferi which causes a multi-organ involvement. It is endemic in North America and Europe, but not very commonly seen in India. Neurological manifestations (Lyme’s Neuroborreliosis,) can occur in both the early and late disseminated stages, and the classic triad consists of aseptic meningitis, painful radiculoneuritis, and cranial neuropathy. If untreated, it can be fatal and may lead to significant morbidity. We report a case with neuroborreliosis who developed acute onset and rapidly progressive bilateral vision loss, and we also report characteristic features on neuroimaging, including a characteristic “rounded M sign.” This unusual presentation, along with the characteristic imaging features, should be borne in mind to avoid misdiagnosis.

Published: December 2022

Objectives:

Febrile neutropenia (FN) is a medical emergency requiring prompt diagnosis of underlying infection and early administration of antibiotics. Updates about the spectrum and resistance patterns of pathogens isolated are essential for the successful management of FN.

Materials and Methods:

The purpose of this study was to describe the clinical profile, outcome, infective pattern and the clinical utility of procalcitonin (PCT) and C-reactive protein (CRP) in febrile neutropenic children, admitted to our center between 2017 and 2019. Children aged <18 years with confirmed malignancy and FN were enrolled in the study.

Results:

The study population was 54 patients. A total of 90 episodes of FN were noted. Hematologic malignancies accounted for 74% of the cases. Only 15 (16.6%) of the study population had clinical foci of infection. Overall culture positivity was 20 %. Among the children with central venous catheter, 21.8% had culture positivity. The most common bacterial isolates were Gram-negative bacilli, withAcinetobacterbeing the most common pathogen. The overall mortality rate was 5.5%. Among 18 culture positive cases, CRP was positive in 10 (55.5 %) cases and PCT was positive in 12 (66.6 %) cases.

Conclusion:

Gram-negative organisms are the major infective agents in developing countries. Central venous catheter remains the foci of infection in these patients. Raised CRP and PCT are predictors of complications during FN.
Observing Coordination and Reactivity between an Organohalide and Cesium Lead Halide Nanoparticles via DOSY and ROSY NMR
Authors: Ripka Emily Grace , Deschene Christina , Franck John , Maye Mathew
Published: December 2022

Cesium lead halide (CsPbX3, X = Cl, Br, I) nanoparticles have an inorganic core with the propensity for ion exchange that is surrounded by a labile ligand capping shell which facilitates ligand exchange, two characteristics that are important for chemical reactions and heterogeneous catalysis. This study followed a model reaction between the organohalide 2-Bromododecanoic Acid (2-Br) and four different oleic acid (OAc), oleyl amine (OAm) capped CsPbBr3-xIx in-situ with 2D diffusion ordered nuclear magnetic resonance spectroscopy (DOSY) and relaxation ordered spectroscopy (ROSY). The observed diffusion coefficient (D) and relaxation time (T1) changes measured in DOSY and ROSY, respectively, indicated 2-Br binding and reactions at the CsPbBr3-xIx interface, forming a more bromine rich inorganic product, and both an elimination (2-dodecenoic acid, 2-DDAc), or halide exchanged organic product (2-Iodododecanoic acid, 2-I). Photoluminescence spectroscopy was also used to monitor the reactions. The results indicate that the reactions proceed without the need for any external light activation, however when photoactivated, a preference towards the 2-I formation was observed.

Ti(IV) and Ti(III) complexes using the tBuPCP ligand have been synthesised (tBuPCP = C6H3-2,6-(CH2PtBu2)2). The [tBuPCP]Li synthon can be reacted with TiCl4(THF)2 to form (tBuPCP)TiCl3 (1) in limited yields due to significant reduction of the titanium synthon. The Ti(III) complex (tBuPCP)TiCl2 (2) has been further characterised. This can have half an equivalent of halide abstracted to form [{(tBuPCP)TiCl}2{μ-Cl}][B(C6F5)4] (3) and can also be methylated forming (tBuPCP)TiMe2 (4). All the Ti(III) complexes have been characterised using EPR and x-ray crystallography, giving insight into their electronic structure, which is further supported by DFT calculations.

Overcoming the energy barrier in CO2 reduction is a key avenue in the development of sustainable carbon capture and recycling systems spearheading against the climate emergency. Diamond, a wide-bandgap material, has shown promise in this aspect due its ability to produce highly reductive solvated electrons when irradiated with deep UV light. This requirement for high-energy optical illumination, however, hampers its sustainable application and limits its useful lifetime. Here we show the photosensitization of nanoscale detonation diamond in reductive photoelectrocatalysis through surface functionalisation with a ruthenium-based dye, demonstrating solar-light driven turnover of CO2 using the unique properties of diamond. The hybrid photosensitizer-nanodiamond materials demonstrated good colloidal and photochemical stability. The nature of electronic conjugation between diamond and photosensitizer was elucidated through X-ray absorption, transient optical absorption, and ultraviolet photoemission spectroscopies, with CO2 turnover significantly improved under solar conditions for photosensitized systems. The potential for photoexcited electron transfer (PET) mediated photosensitization in reductive diamond catalysis opens the way for further sustainable applications using diamond as a sustainable photoelectrocatalyst.
Pressure-driven batch distillation optimal control for acetone-methanol separation
Authors: Stojkovic Marija
Published: December 2022

Over the last fifteen years, immense progress has been made in the research of pressure-swing batch distillation. The challenge lies in the fact that certain pressure-sensitive azeotropic mixtures cannot be separated in a regular open batch mode, with an acceptable outcome. Throughout most of this text, findings are to contradict previously grounded facts. Acetone-methanol separation by pressure-swing batch distillation in a mixed double system consisted of a regular and inverted double column is a process under the investigations. In this work, a complete global solution to the optimal control problem in form of a sequential synthesis of controlled trajectories, is derived. During this study, the optimal reflux strategy through cyclic operation was extended to the separation of a non-ideal minimum boiling azeotrope of industrial significance. The influence of the liquid ratio and tank volume on the control pattern and energy requirement are evaluated as well.

Published: December 2022

Cobalt-based layered hydroxides (LHs) stand out as one of the best families of electroactive materials for the alkaline oxygen evolution reaction (OER). However, fundamental aspects such as the influence of the crystalline structure and its connection with the geometry of the catalytic sites remains poorly understood. Thus, to address this we have conducted a thorough experimental and in silico study on the most essential Co-LHs (i.e.: ɑ-LH, β-LH and LDH) which allows us to understand the role of the layered structure and coordination environment of Co atoms on the OER performance. The ɑ-LH, containing both octahedral and tetrahedral sites, behaves as the best OER catalyst in comparison to the other phases, pointing out the role of the chemical nature of the crystalline structure. Indeed, density functional theory (DFT) calculations confirm the experimental results which can be explained in terms of both, the significant reduction of the Egap, due to the presence of tetrahedral sites, as well as the more favourable reconstruction of the ɑ-LH structure into active Co(III)-based oxyhydroxide-like phase. Furthermore, ex-situ X-ray diffraction and absorption spectroscopy reveal the permanent transformation of ɑ-LH phase into an unprecedented highly reactive oxyhydroxide-like structure under ambient conditions. Hence, our findings highlight the key role of tetrahedral sites on the electronic properties of the LH structure as well as their inherent reactivity towards OER catalysis, paving the way for the rational design of more efficient and low-maintenance electrocatalysts.

The synthesis of imines denotes a cornerstone in organic chemistry. The use of alcohols as renewable substituents for carbonyl-functionality represents an attractive opportunity. Consequently, carbonyl moieties can be in situ generated from alcohols upon transition-metal catalysis under an inert atmosphere. Alternatively, bases can be utilized under aerobic conditions. In this context, we report the synthesis of imines from benzyl alcohols and anilines, promoted by KOtBu under aerobic conditions at room temperature in the absence of any transition-metal catalyst. We present a detailed investigation of the radical mechanism underlying the reaction revealing a complex reaction network, which supports the experimental findings.

We describe the synthesis of trihydroxylated cyclohexane β-amino acids from (–)-shikimic acid, in their cis and trans configuration, and the incorporation of the trans isomer into a trans-2-aminocyclohexanecarboxylic acid peptide chain. Subsequently, the hydroxyl groups were partially or totally deprotected. The structural study of the new peptides by FTIR, CD, solution NMR and DFT calculations revealed that they all fold into a 14-helix secondary structure, similarly to the homooligomer of trans-2-aminocyclohexanecarboxylic acid. This means that the high degree of substitution of the cyclohexane ring of the new residue is compatible with the adoption of a stable helical secondary structure and opens opportunities for the design of more elaborate peptidic foldamers with oriented polar substituents at selected positions of the cycloalkane residues.

Исследование данной тематики в рамках региона в историографии отсутствует. В статье рассмотрена проблема достоверности дикторских материалов, прослеживается динамика развития их тематики. По мере освобождения городов и сел Калининской области власть стремилась сразу же наладить там радиовещание, поскольку радиопередачи служили мощным средством идеологической работы, обращение в радиопередачах к темам культуры позволяло направлять и организовывать культурно-просветительский досуг населения, поднимало людей на восстановление разрушенных культурных объектов, стимулировало развитие местной культуры и творчества.

MATERIALS OF A SCRIST'S DESCRIPTION OF THE CITY OF TVER OF POTAP NARBEKOV, 1625/26
Authors: Алексей Анатольевич Фролов,
Published: December 2022

В статье выявляется круг материалов писцового описания г. Твери, проведённого в середине 1620-х гг. Потапом Нарбековым. Оно чаще всего привлекается историками и археологами при изучении исторической топографии и социально-экономического облика города в XVII в. В научном обороте сейчас находятся материалы этого письма только в одной версии - по публикации 1901 г., в основе которой лежит копия (предположительно XIX в.) с Выписи, сделанной в 1681 г. с подлинной книги. Выборочное сличение публикации с Выписью выявляет многочисленные дефекты издания. Автор отмечает ряд нюансов, которые не позволяют рассматривать текст Выписи как полноценное отражение материалов писцового описания. Помимо Выписи 1681 г. ценным источником сведений о письме П. Нарбекова служит фрагмент подлинной книги, который впервые получил характеристику в источниковедческом отношении. В статье излагается ряд наблюдений над рукописью, позволяющих судить об архивной судьбе документального комплекса в XVII в.

The article reveals the range of materials of the scribe's description of the city of Tver, carried out in the mid-1620s. Potap Narbekov. It is most often used by historians and archaeologists when studying the historical topography and socio-economic appearance of the city in the 17th century. The materials of this letter are now in scientific circulation in only one version - according to the publication of 1901, which is based on a copy (presumably of the 19th century) from the Excerpt made in 1681 from the original book. A selective comparison of the publication with the Excerpt reveals numerous defects in the publication. The author notes a number of nuances that do not allow us to consider the text of the Extract as a full-fledged reflection of the materials of the scribe's description. In addition to the Extract of 1681, a valuable source of information about P. Narbekov's letter is a fragment of a genuine book, which for the first time received a characteristic in terms of source studies. The article presents a number of observations on the manuscript, which make it possible to judge the archival fate of the documentary complex in the 17th century.
INTERACTION AS A CRITERION OF MATERIALITY AND THE BASIS FOR OPERATIONAL DEFINITION OF MATTER
Authors: Владимир Михайлович Самсонов, , Евгений Кузьмич Петров,
Published: December 2022

Проанализированы имеющиеся определения материи (П. Гольбаха, Г.В. Плеханова и В.И. Ленина). Сделан вывод о том, что для этих однотипных определений характерен сенсуализм. Кроме того, сформулирован вывод о том, что не движение, как полагал Ф. Энгельс, а взаимодействие является основным атрибутом, признаком материи, критерием материальности. Взаимодействие данного объекта с другими материальными телами, включая физические приборы и органы чувств человека, положено в основу предложенного нами определения материи.

Analyzing the existing definitions of matter (P. Holbach, G.V. Plekhanov and V.I. Lenin), we made a conclusion that sensualism inherent to these similar definitions may be considered as their main drawback. In addition, it was concluded that not motion, as F. Engels believed, but interaction is the main attribute, a signature of matter, a criterion of materiality. The interaction of an object with other material bodies, including physical instruments and the human sense organs, is the basis of our operational definition of matter. Concepts of the energy and mass, considered as basic characteristics of material bodies and material physical fields, are also discussed.
