The issue of delamination occurring on PACF materials is a structural application failure due to poor mechanical strength. The bonding process of composite materials between layers using fused deposition modeling (FDM) printing affects the tensile strength of the material. The main objective of this study was to study the shear strength of polyamide reinforced carbon composite (PACF) materials by using shear test method and to study the effect of fractured or delamination surfaces during shear testing. In this study, PACF material was printed using FDM technique through Ultimate S3 machine. A total of 20 printed PACF specimens underwent a semi-overlapping adhesion process using Loctite E-20HP epoxy adhesive which required curing for 24 hours at room temperature. Shear test methods were performed on PACF composite specimens using Universal Testing Machine. Furthermore, PACF samples were conducted experiments to determine the physical properties of the composites of the material as well as Scanning Electron Microscopy (SEM) experiments through fractured or eliminated surfaces. Based on the results obtained, the PACF material has a high shear tensile strength compared to that of epoxy adhesives with an average rate of 1.6 MPa respectively. This is may due to the low curing temperature and the thick epoxy layer. It was observed that the FDM printing method produces a porous print layer that can facilitate delamination to occur.

Hydrogen is the main choice of renewable fuel since it brings significant benefits compared with the other conventional fuels, such as the use of waste substrate, cleaner and highest energy density. Biological hydrogen production route is cost efficient since it can be processed in ambient conditions, easy operational techniques while keeping the environment safe. Dark fermentation to produce bio-hydrogen has received widespread attention from researchers in the present decades especially due to not requires light sources. This work is a study of the optimization of process conditions particularly pH and temperature of a dark fermentation bioreactor to produce Bio-H2 from palm oil mill effluent (POME) by using fuzzy logic controller. The simulation started by developing process and instrumentation diagram (P&ID) of bioreactor. Then a conventional PID controller and fuzzy logic controller were simulated by using MATLAB SIMULINK and the results were compared with each other in terms of safety aspect. The temperature of 37oC and pH of 6 is the optimum conditions that needs to be maintained to yield the hydrogen at 2.79 mol H2 mol-1 glucose. The pH is able to reach optimum value at 600s and 30s by using the PID controller and fuzzy logic controller, respectively. Same goes to temperature control, where the parameter reaches optimum value at 200s and 0.3s respectively. Based on these promising results, fuzzy logic controller is a good replacement for the conventional control systems since it requires shorter time to optimize process conditions, consequently making sure the safety aspect is well guaranteed.

The current study investigated the physical properties and rheological characteristics of asphalt cement (AC) modified by nano ironoxide (Fe3O4) and nano silica (SiO2) particles. Seven different blends including base AC, Acrylete-StyreneAcrylonitrile (ASA)/ Nanosilica (Si) and ASA/ Nanoironoxide (Fe) were the subject of experimental investigations. ASA was used at 5% for all modified blends while the nanomaterials were blended in 3, 5 and 7% concentrations by the weight of AC. Temperature susceptibility, rotational viscosity (RV) and storage stability for the base and polymer nanocomposite modified asphalt cement (PNCAC) were evaluated by the physical testing procedures while the frequency sweep test and the multiple stress creep recovery (MSCR) tests were conducted using a dynamic shear rheometer. The results showed that, the viscoelastic properties of the ASA/Si and ASA/Fe modified binders were improved when subjected to a range of temperatures and loading conditions. ASA/Fe composite modified AC demonstrated superior high temperature performance characteristics while ASA/Si composite modified AC although presented less significant improvement at the high temperature conditions, it was also able to improve the intermediate temperature fatigue resistance of asphalt more than the ASA/Fe composite modified AC. The optimum concentration of additives were found to be 3 and 5% for the ASA/Fe and ASA/Si modified AC respectively. Further addition of nanomaterials beyond the abovementioned concentrations resulted in degradation of the enhancement in physical and rheological properties of PNCAC, which was associated to the occurrence of agglomeration of nanoparticles and phase separation between the polymer-nanomaterial-asphalt matrix.

The culture of business construction, which currently focuses on winning new project tenders and revenue based on terms, is significantly affected when activity restrictions occur. What happened during the pandemic in 2019 noting that 25% of construction companies could not survive the pandemic. As a result, various innovations need to be deployed to save the business from bankruptcy, so that new revenue streams are needed outside of the ongoing business, one of which is the development of social media. Social media has an increasingly prominent role in impact interactions, and it has been proven that this sector does not experience a decline when almost all sectors are bad in the pandemic era. This research will examine how social media can have an impact on the construction industry, not only increasing participation and driving public opinion but can also be a new revenue stream for companies. This research will focus on companies engaged in toll road infrastructure developer in Indonesia. The case study was designed to combine both qualitative and quantitative methods. The results show that the use of social media in infrastructure development businesses that focus on corporate branding can be developed into a new revenue stream with a content focus, namely project progress, educational shows, and the use of technology impact the influence and awareness.
Examination of the Participation of Roma Families in the Educational System: Difficulties and Successful Practices
Authors: Merchán-Ríos Rocío , Abad-Merino Silvia , Segovia-Aguilar Blas
Published: March 2023

Discrimination faced by Roma students leads to high rates of academic failure and school dropout while structural barriers continue to hinder their inclusion in the education system. Educational research shows that the engagement of families contributes to inclusion, academic success, and improvement of the quality of education. However, educational barriers and school segregation practices show the traditional deficiency of effective tools to promote family participation among the Roma population. Understanding the barriers that Roma families find to participate in the educational system involves the examination of complex processes and dynamics that we observe in practice and the role of the different actors in the schooling of Roma students. Schools as Learning Communities provide the democratic scenario to develop the type of relational and collaborative conditions that help both educators and families to participate in successful educational actions linked to school performance. The development of family engagement action plans connected to student achievement and the incorporation of the perspectives of Roma families can successfully increase their opportunities and expectations in the education system.

La asistencia personal es un instrumento clave para la promoción de la autonomía personal y la vida independiente por parte de las personas con diversidad funcional (discapacidad). Su implantación en España llegó con la Ley 39/2006, de 14 de diciembre, de promoción de la autonomía personal y atención a las personas en situación de dependencia. Actualmente, la formación que deben tener las profesionales que la ejercen es objeto de debate. Por ello, se acude a datos oficiales del Sistema para la Autonomía y Atención a la Dependencia y se realiza un estudio cuanti-cualitativo con un cuestionario ad-hoc, de preguntas abiertas y cerradas, distribuido a 52 profesionales de entre 23 y 57 años (M=33,29; DT=8,39). La información recogida se analizó a nivel cuantitativo con SPSS 22 y a nivel cualitativo con NVivo 12. Una amplia mayoría de las profesionales son mujeres y de su discurso se deduce que sienten la necesidad de una mayor formación para ejecutar un servicio más respetuoso y de mayor calidad. En conclusión, la asistencia personal no tiene la relevancia esperada en España y parece que la opción de que las profesionales cuenten con formación de base universitaria para ejercerla sería interesante atendiendo a sus experiencias.

Principles of Customization for Models of Complexly Organized Intelligent Systems
Authors:   Kuban State University, Krasnodar, 350040, Russian Federation, Kostenko K. I.
Published: March 2023

The article presents classification and formats developed by the author for descriptions of operations for expanding and detailing formal models of intelligent systems. Operations are proposed that allow automating the processes of creating such models adapted to the properties of subject areas. Model descriptions are based on the formalization of universal parameters and properties associated with intelligent systems. The basis for building various models is the universal model. It presents the concepts and properties of knowledge representation formalisms, descriptions formats of knowledge flows and processes and control elements of intelligent systems. When creating a universal model, the principles of hierarchy and plurality of descriptions are taken into account. This provides a high initial level of the de­sign process based on generalizing unified designs of the universal model. Descriptions of additional common model elements adapt the initial universal model. Such an approach allows overcoming the problem of multiple properties of intelligent systems, reflecting ideas about them that formed in different fields of knowledge. Transformations of the universal model into a model with given properties are implemented as transformations of formalized descriptions of parameters and properties. Transformations adjust the universal model, from which general and applied models of intelligent systems are constructed. Model execution algorithms allow you to create specific intelligent systems. Such systems exist as software implementations of algorithms in the digital spaces of these areas.

Modern aphoristic sayings in Arabic online communication
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, KUCHERENKO A.
Published: March 2023

The texts of aphoristic orientation in the Arabic cultural and entertaining content of the social media are analysed. The subject of the study involves linguistic, sociolinguistic and pragmatic features of Arabic aphoristic Internet sayings. The analysis of more than 500 text units reveals that aphoristic posts are published online in the form of memes in order to express cultural, moral and ethical values and orientations, philosophical and aesthetic views of users, as well as for their emotional support. It was found that the main functions of aphoristic memes are emotional, communicative and phatic with such sayings mainly including motivational and narrative messages, advices, greetings, and appeals, that are often accompanied by a chain element inherent in the social networks (such as a direct call to spread the message). On top of that the thematic classification of the studied memes was offered, with the following themes being involved: human behaviour and character, emotions and experiences, moral and ethical values, philosophical reflections on the attitudes to life, human relationships, everyday life, etc. The linguistic features of expression of the binary opposition "self – other" in the context of its influence on the emotional expressiveness of the aphoristic lexicon are outlined as well. On the other hand, it is noted that the important feature of aphoristic memes is the active use of emotionally expressive lexis, colloquial elements, figures of speech (metaphors, epithets, similes, etc.), verbs of the imperative mood. The language code in the aforementioned sayings is represented primarily with Modern Standard Arabic (with minor deviations). This reflects the identity of a wide circle of Arabic-speaking online users, regardless of their affiliation with a particular ethnic, social or gender group.
The speech acts of "offer" and "refusal" in the communicative behavior of Persian native speakers
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, MAZEPOVA O.
Published: March 2023

The ethno-specific functioning of the speech acts of "offer" and "refusal" in the Persian-speaking communicative space is analysed. The division into positive and negative face, offered within the theory of linguistic politeness by sociolinguists P. Brown and S. Levinson is specifically applied in the context of the Persian politeness system ta'ārof, which is of fundamental importance for understanding the communicative behavior of Persian native speakers. This is due to differences in some cultural values in Western and Oriental societies, in particular, the collectivist nature of Iranian society, where the interests of the community prevail over the interests of an individual. The high context of Persian linguistic culture is demonstrated by the fact that offers and refusals, qualified by the theory of linguistic politeness as face-threatening acts (FTA), are not perceived by Persian native speakers as those, since they are used as means of expressing politeness and contribute to the harmonization of relations between communicators. Special attention is paid to the analysis of ritual or ostensible offers and invitations, which are not supposed to be accepted immediately, but should demonstrate care and respect to the interlocutor. Ignorance of the rules of communication or neglecting these may cause the loss of speaker's face before his interlocutor. Refusals, like offers and invitations, can also be real or ostensible. The article considers only ostensible refusals, which in Persian cultural complex ta'ārof serve as means of face-works and are regarded as integral parts of polite communication. It is thought that initially any offer or invitation should be rejected to demonstrate thus the readiness to follow the appropriate social convention, with any offer to be accepted only after tenacious insisting from the initiator's side. The refusal should be done in a gentle and reasonable way to avoid threatening the addressee's face. Meanwhile, not-native speakers of Persian may regard ostensible speech acts as imposing and hypocritical, since their true motivation is hidden from direct observation. Sometimes even native Iranians can hardly distinguish between real speech acts and ostensible ones. Therefore, a careful study of the specifics of their functioning is the key to successful intercultural communication with them. The analysis of offers and refusals functioning in various Oriental communicative cultures reveals many common features, which may provide remarkable perspectives for comparative researches in this field.

Lexical, grammatical and stylistic negative phenomena in the language of Japanese mass culture (using the language of Japanese fashion magazines as an example)
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, KOMARNYTSKA T.
Published: March 2023

The paper is devoted to the analysis of lexical, grammatical and stylistic destructive phenomena typical for the language of mass culture, based on the material of the Japanese fashion magazine "Cosmopolitan Japan". In the field of the vocabulary of the language of fashion magazines, we observe a proliferation of unmotivated English borrowings, which mostly duplicate the meaning of genuine Japanese words, and therefore do not enrich the lexicon. A considerable number of such words are incomprehensible to Japanese readers, and therefore play not an informative, but an emotional role, decorating the text and making it "fashionable" and "stylish". The number of English borrowings in a fashion magazine may even exceed the number of Japanese words. In the field of morphology, a characteristic feature of the language of mass culture is the presence of hybrid units as the result of hybrid word formation and are mostly formed according to the "English borrowing + Japanese suffix" model. This method is the most common in creating verbs, adjectives, and adverbs. The created morphological hybrids do not correspond to either Japanese or English word formation norms, and therefore are a destructive phenomenon that negatively affects the language. In the field of syntax, we observe an overuse of syntactic expressive figures, in particular those based on missing speech components (ellipsis, nominative sentences). The predicate (or its verb part) usually undergoes reduction, which makes such sentences fragmentary, similar to spontaneous speech of a colloquial and everyday nature. Excessive use of ellipsis and nominative sentences interferes with the established syntactic norms of the Japanese language. The overuse of parcellation as a phenomenon that destroys the traditional syntactic structure of the Japanese sentence (which is characterized by a fixed order of words) seems to be equally destructive. A negative stylistic phenomenon is also the mixing of expressive styles and the indistinction of speech registers, which is also critical for the Japanese language, that is characterized by a category of politeness and a clear distinction between "high" and "low" styles. The above-mentioned phenomena are destructive, interfering with the recipient's "sense of language" and language norms, which can lead to a significant decline in language culture among young people being the main consumers of mass culture.

Organic rankine cycle systems with mixture of pure fluids: On infeasible fluid’s fractions due to the interaction between the mixture glide and the hexs pinchs

Published: March 2023

The Organic Rankine Cycle (ORC) is a promising technology for power generation from low-grade heat. The selection of working fluids is one of the important key points to improve the performance of an ORC system. Zeotropic mixtures show promising performances as working fluids. In fact, their temperature glide during phase change enables better match between the working fluid and the heat source/sink temperatures. In order to reveal the performance of mixture in ORC system, this paper deals with the thermodynamic model of the subcritical Organic Rankine Cycle (ORC) systems driven by low grade heat source while using zeotropic mixture working fluids with a special consideration to the interaction between phase change glides and the pinch value and their location in both the evaporator and the condenser (HEXs). Zeotropic mixtures of seven pure fluids are evaluated as working fluids for a subcritical ORC system. The mass fraction effects of mixtures on the thermal efficiency are analyzed. For given working conditions (working fluid mass flow, pressure and bubble temperature) the results show that for each considered zeotropic mixture there exist mass fraction ranges that are not consistent with the pinch values constraint in the HEXs and leads to so-called ‘infeasible zones’ with unreal HEXs dimensions. Results shows also that, out of these “infeasible fractions” zone, keeping unchanged the working conditions, the thermal performances of ORC system using zeotropic mixture are always better than the thermal performances of the same systems using the correspondent pure fluids. In addition, out of these highlighted “unfeasible zones” it was found that mixture with high temperature glide improve the thermal efficiency of ORC system.
Elementos para a construção de uma sociologia ambiental (Paper 381)
Authors: Sobrinho Sebastião Aluizio Solyno
Published: March 2023

Este trabalho tem por objetivo discutir as contribuições de teóricos das sociologias clássica e moderna, articulando elementos para a construção de uma sociologia ambiental. O texto se desenvolve em quatro tópicos. No primeiro, analisam-se as contribuições de Clifford Geertz e Michael Redclift, para um conceito de desenvolvimento sustentável que leve em conta as diferentes visões de cultura e subsistência entre o mundo industrializado e os países em desenvolvimento. O segundo tópico trabalha as controvérsias a respeito das contribuições dos Clássicos à questão ambiental, destacando Émile Durkheim, Max Weber e Karl Marx como fundadores de um paradigma antropocêntrico na Sociologia, cujas influências se projetam até o nascimento de uma sociologia ambiental propriamente dita, na segunda metade do século XX. O terceiro tópico discute as contribuições da Escola de Frankfurt na constituição de uma Teoria Crítica da sociedade industrial, e os desdobramentos em Habermas e Luhman na proposição de uma democracia deliberativa, que abra espaço para novas formas de produção e uma melhor relação entre o homem e a natureza. Por fim, à guisa de conclusão, o quarto tópico destaca as lições aprendidas para o desenvolvimento teórico da própria sociologia ambiental.Palavras-chave: Sociologia ambiental. Interdisciplinaridade. Sustentabilidade. Subsistência.
Mercantilizar para implementar: o diálogo de Alto Nível sobre Financiamento na COP 24 como alegoria do planejamento do desenvolvimento global (Paper 397)

O artigo analisa Conferência das Partes (COP) 24, em Katowice, Polônia, a partir do Terceiro Diálogo de Alto Nível sobre Financiamento da Convenção Quadro das Nações Unidas sobre Mudanças Climáticas (UNFCCC, na silga em inglês), realizado nesse mesmo evento. Nesta análise, atenta-se para os aspectos, conflitos e contradições na agenda política climática e de desenvolvimento associados à regulamentação do Acordo do Clima, também conhecido como Acordo de Paris. Observa-se que relações de colonialidade que contribuíram para constituir as assimetrias que produziram – e reproduzem – o que se denomina Norte e Sul Global tem se repetido, particularmente, nas decisões relativas a quem se deve financiar e a forma como se deve fazer isso para a implementação do acordo. Argumenta-se a partir de etnografia realizada na reunião citada aqui diretamente e do acompanhamento documental desta reunião e das cinco outras negociações que a antecederam, desde 2014, que tais assimetrias possivelmente voltaram a se repetir na forma de mais periferização e produção de desigualdades em regiões como a amazônica. Na mesma região, fundos de financiamento climático, como o Fundo Amazônia, podem mudar sua forma de composição e direcionamento, reforçando tendências globais de privatização e mercantilização do financiamento ao desenvolvimento global.Palavras-chave: Financiamento Climático.

Published: March 2023

Enfoques prohibicionistas y de criminalización, sumados a la intervención estatal desde un modelo de seguridad ciudadana y no de salud pública en Colombia han obstaculizado la comprensión de los hábitos de consumo de sustancias psicoactivas (SPA) en jóvenes, limitando los datos a una lógica de lucha contra las drogas. El aislamiento preventivo por el Covid-19 en 2020 constituyó una oportunidad de investigación sobre los hábitos de consumo en jóvenes usuarios de SPA y los cambios presentados en la ciudad de Medellín. Se desarrolló un estudio con enfoque cuantitativo de corte transversal con una muestra de 817 jóvenes seleccionados por muestreo no probabilístico, quienes diligenciaron un formulario en Google Drive, sobre consumo de SPA, características sociodemográficas y prácticas relacionadas. El uso de métodos clustering permitió evidenciar grupos de sustancias con similitudes en su prevalencia anual de consumo; y se identificaron patrones de consumo según lugar de residencia. Niveles socioeconómicos y grupos de edad no están asociados a una finalidad específica en el uso de SPA. Los hallazgos muestran una disminución en las prevalencias de consumo durante el aislamiento preventivo, y también se evidencian prácticas y hábitos en la población joven que relacionan el consumo de SPA desde una lógica recreativa.

The present study brings up the Racial and Ethnic Quota Policy in Higher Education from a perspective of social/distributive justice and the affirmation of black identity, based on the first experiences of the Institute of Society Sciences and Regional Development of the Fluminense Federal University (ESR / UFF) with the approval of Federal Law No. 12.711/2012, and the implementation of ENEM/SISU. This is a qualitative study, through bibliographic, documentary and field research, with the objective of analyzing, among other aspects, whether the policy contemplates the demands of its target audience, that is black quota students enrolled in the period from 2013 to 2015, in the institution's highest and lowest demand course. Based on the criteria proposed as an investigation, it can be considered that the issues involving the social and economic aspects of the Quota Policy stood out in the interviewees' testimonies. However, regarding the self-affirmation of black people, their identity and their social place, the policy has not yet been well worked, ratifying the issue of a positive identity, though lacking promotion for cultural justice.

Pandemia COVID-19 wpłynęła na życie społeczne i gospodarcze, zaburzając normalny rytm funkcjonowania niemal każdego człowieka. Nadzieją na powrót do normalności było wynalezienie szczepionki i jej działania prewencyjne. Niniejsza praca ma na celu zidentyﬁ kowanie, w jaki sposób przebieg pandemii koronawirusa wpłynął na postrzeganie wakcynacji w społeczeństwie.

Niniejsza praca została napisana na podstawie wykonanych badań wtórnych, to jest analizy danych statystycznych dostępnych w bazach światowych (WHO, Our World In Data) oraz krajowych (CBOS, dane Ministerstwa Zdrowia), obejmujących okres 2019–kwiecień 2022. Ponadto przeprowadzono badania pierwotne, których celem była identyﬁ kacja postaw Polaków wobec szczepień. Badania zostały zrealizowane na próbie 152 respondentów w maju 2022 roku. Zgromadzone wyniki pozwoliły na sformułowanie wniosków. Badania wykazały, że przed pandemią obowiązkowym szczepieniom poddawało się 92 % ankietowanych. Z kolei 76% przyjęło szczepienia przeciw wirusowi SARS-CoV-2. Oznacza to, że 16% było negatywnie nastawionych do szczepienia covidowego. Zaszczepiło się 60% Polaków, czyli o 8 punktów procentowych poniżej średniej europejskiej, a wśród już zaszczepionych ankietowanych tylko 42% planuje przyjąć trzecią dawkę. Ponadto ponad połowa (51%) uważa, że ich wiedza na temat szczepień nie jest wystarczająca.
Substytucja leków w aptece ogólnodostępnej podczas pandemii COVID-19

Substytucja leku w aptece polega na zamianie preparatu, pierwotnie zaordynowanego na recepcie przez osobę uprawnioną do jej wystawienia, przez osobę uprawnioną do wydawania produktu leczniczego. Proces ten zachodzi podczas zakupu leku w aptece ogólnodostępnej. Uczestniczą w nim pacjent oraz farmaceuta lub technik farmaceutyczny. Kwestie prawne zamiany leku reguluje ustawa refundacji leków, środków spożywczych specjalnego przeznaczenia żywieniowego oraz wyrobów medycznych z dnia 12 maja 2011 roku. W Polsce możliwa jest substytucja leku oryginalnego na lek generyczny, leku generycznego na oryginalny lub też leku generycznego na inny generyczny. Lek oryginalny to taki, który został wprowadzony na rynek jako pierwszy i podlegał początkowo ochronie patentowej. Leki generyczne są według Światowej Organizacji Zdrowia zamiennikami leku oryginalnego. Nie posiadają patentu i mogą zostać wprowadzone dopiero po wygaśnięciu ochrony patentowej leku oryginalnego. Proces dopuszczania ich do obrotu jest uproszczony w stosunku do leku oryginalnego.

Powodami zamiany leku w aptece są najczęściej względy ekonomiczne, czyli niższa cena zamiennika lub niedostępność pierwotnie zaordynowanego leku w aptece. Pandemia COVID-19 przyczyniła się do braków leków w aptekach, szczególnie na jej początku. Przyczyn deﬁcytów poza przewyższeniem podaży przez popyt upatruje się w tym, że zarówno leki, jak i surowce są w znacznym stopniu importowane z Chin i Indii. Niniejsze rozważania zawężono tylko do leków dostępnych na receptę.

Celem pracy jest przedstawienie zjawiska substytucji leków w aptece ogólnodostępnej, które to zjawisko można zaobserwować podczas pandemii COVID-19. Analizie poddano dane rynkowe, udostępnione na potrzeby niniejszej pracy przez PEX PharmaSequence Sp. z o.o.

Podczas pandemii COVID-19 nastąpił wzrost skali substytucji. W 2019 roku zamienionych zostało 3,73% wszystkich leków przepisanych na recepcie, podczas gdy w 2020 było ich 5,50%. Wnioski wynikające z publikacji wskazują na konieczność dalszej obserwacji zjawiska zamiany leku w aptece przez osoby upoważnione do wydawania produktów leczniczych i ciągłego podejmowania problemu z perspektywy różnych dyscyplin naukowych.

Purpose: To consider the possibility of remote calibration of electronic travel templates in the Far North districts. Verification and calibration of measuring instruments are the most important metrological operations aimed at the support of measurement uniformity and allowing to determine being measured quantity values with the indications of a measuring instrument, to define corrections to its indications and to estimate the inaccuracy of these instruments. With society and technology development, the course on the improvement of calibration procedures of measuring instruments and automation of processes has become relevant. Active introduction of programmable measuring instruments has opened up opportunities for the introduction of new ways of transmitting the units of physical quantities. To show the advantage of remote calibration of electronic trip templates in comparison with conventional calibration in economic and time terms since the need to transport a trip template to distant metrology centers for periodic calibration check disappears. Methods: Conducting experiment of remote calibration of electronic trip template at a big distance using Internet global network and special software, namely the programs "Integration Module", "Neva-1 Service Software" "LetsView", "Unitess View", "Agent Mail.ru". Results: The possibility of remote calibration was determined, the programs necessary for the work were tested, the results of experimental study with the use of Internet global network were presented and calibration protocol was obtained. Practical significance: The possibility of introducing remote calibration has been determined which will allow to reduce cost for transportation of electronic trip templates upon their periodic calibration and to lower the required time for metrological maintenance.
