Predictive Maintenance of Compressor Using ThingSpeak IoT Platform
Authors: J. m. Tahir Shivan , AKIN Erhan
Published: July 2021

Any instrument or machine that needs to be monitored and inspected on a regular basis to ensure its long life and proper maintenance. Machine condition monitoring in the time and frequency domain is unquestionably required to ensure reliability. Condition monitoring is a method of observing a machine's condition parameter (vibration, temperature and etc.), with the explicit objective of detecting a substantial change that could indicate the onset of a malfunction It's an important part of compressor predictive maintenance and lowering compressor downtime. In today's world, the Internet of Things (IoT) is the most effective approach and technology for continuously monitoring the state of any machine. We've employed MEMS sensors to detect misalignment, non-linearity, and other anomalies., Through the Wi-Fi module ESP8266, vibrations and temperature in compressors, as well as changes in signals, will be communicated to the cloud. These signals are in order in the temporal domain. The Fast Fourier transform is used to examine and convert the time domain sequence into the frequency domain.

ABSTRACT

Tooth avulsion is one of the common traumatic injury results in complete extrarticulation of tooth from its socket since resulting in damage to the periodontal tissues. Maintaining viability of the periodontal cells remains a challenge to the clinician to reimplant the avulsed tooth. Since various avulsion media are used in dentistry a novel medium Placentrex derived from 0.1 gm. of fresh term, sterilized, infection-free human placenta which has unique pharmacological effects like enhancement of wound-healing, anti-inflammatory, antioxidant and analgesic effect is compared with HBSS and Propolis media in freshly extracted, non carious, non restored, periodontal diseases free human teeth which are indicated for orthodontic treatment purposes were used. The extracted teeth were placed in the enzyme solution to facilitate detachment of the cells and after ten minutes teeth were removed and 1 ml of solution were collected through micropipette and centrifuged. The stained cells were counted in Neubauer’s chamber under a light microscope at 10× magnification. Conclusion: Placentrex maintained PDL cell viability almost similar to Propolis and significantly better than HBSS.

ANALYSIS OF THE IMPACT OF MINDFULNESS ON QUALITY OF LIFE IN PATIENTS WITH MULTIPLE SCLEROSIS: SYSTEMATIC REVIEW
Authors: Mallmann Fedeger Vitória , Pedri Erica , Guetter Mello Rosiane , Leal Laux Alexandre
Published: July 2021

This study aimed to investigate the impact of the mindfulness-based interventions program on the quality of life of patients with Multiple Sclerosis. A systematic review was carried out based on the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes). For an updated perspective on the topic, the selected articles were published from March 2014 to March 2019. Thus, 10 articles were included in the review and were thoroughly compared. A detailed assessment was carried out to measure the impact of the mindfulness protocol both on the general quality of life and on its specific domains. It can be observed that there is some homogeneity of the results regarding the benefits of the practice of mindfulness in the patients’ general quality of life. Moreover, there was greater evidence of the effects of meditative practice on the psychological domain when compared to the physical domain. Hence, the present study considers the mindfulness program a viable tool to address quality of life in patients with Multiple Sclerosis. The lack of Brazilian studies in the area is highlighted. Also, further studies to evaluate the practice of mindfulness continuously, such as cohort studies, are necessary to elucidate the long-term effects of the protocol.
Promoting the Participation of Indigenous Peoples in Environmental Impact Assessment: Effectiveness of Akwé: Kon Guidelines in Finland
Authors: Onyango Vincent , Wiman Henri
Published: July 2021

Indigenous peoples’ participation in public policy and planning is ascribed in numerous international and national legal instruments as essential to the realisation of their self-determination. This study examines how the Akwé: Kon guidelines (AK) can promote effective indigenous peoples participation in environmental management, especially during environmental impact assessment (EIA). Special focus is drawn on the Finnish context, home of the Sámi indigenous people. The study applies an effectiveness review package by Lee and Colley (1999), supplemented by interview and questionnaire surveys, to analyse how effective the AK have been. It was found that although they were useful in promoting further interaction of the Sámi with authorities, the AK did not address their most fundamental political and legal grievances. This leaves room for EIA policy and practice, in Finland and all other jurisdictions with indigenous peoples, to consider how they can more effectively harness the potentialities in AK.
Migration -Trafficking nexus in Post-Soviet Tajikistan
Authors: Chatterjee Sanchita
Published: July 2021

Human trafficking, for the manipulation of migrant labour, is a violation of human rights. The spike in human trafficking is partly due to the rapid expansion of labour migration in the neoliberal period. The former Soviet zone has become one of the world's major human migration sections in the last decade. The article analyses the case of migration and trafficking in Tajikistan as remittances amounted to nearly half of the country's gross domestic product. In Tajikistan, lack of economic prospects, increasing poverty level, presence of blurred boundaries, leads to the cycle of illicit migration flows which resulted in human trafficking. Human trafficking is a multidimensional issue exacerbated in the countries of destination by poverty and gaps in economic openings versus unmet labour hassles and stern migration commandments. The migration of the Tajik people shortly began after the independence of the country and largely to support subsistence to the families leaving behind. Majority of these migrants prefer Russian federation as their main destination to work where corruption and human trafficking problem is huge. There are limited governing bodies to regulate recruiters' activities, so migrant workers are at the mercy of recruiters who are known to charge exorbitant fees that indebted migrant worker before arriving in their destination countries. Labour trafficking is a global humanitarian issue but there is scarcely any quantitative research on the issue. This study examined labour abuse indicators among migrant Tajik workers in the Russian Federation and the subsequent human trafficking risks with fresh vulnerabilities created by the economic crises and the covid-19 pandemic in 2020.

A produção científica sobre CIM no planejamento e gestão urbana no Brasil
Authors: Barbosa Iara Salles , Pereira Filho Zander Ribeiro
Published: July 2021

As complexas e dinâmicas relações sociais observadas atualmente nos espaços urbanos e o cenário de ubiquidade das novas tecnologias, colocam a prova o padrão utópico e centralizador historicamente empregado no planejamento e na gestão das cidades brasileiras. Nesse sentido, novos conceitos e ferramentas emergem à medida em que as tecnologias computacionais avançam, logo, o ato de planejar e gerir cidades ganham novas possibilidades. Nesse contexto, surge o paradigma City Information Modeling (CIM), modelos de informação utilizados na escala da cidade no armazenamento de dados, desenvolvimento de projetos, gestão e planejamento, capazes de auxiliar nos processos decisórios de políticas urbanas. Diante disso, se propõe neste artigo avaliar, por meio da Revisão Sistemática da Literatura (RSL), a produção científica sobre o CIM referente, restritamente, as abordagens na escala do planejamento e da gestão urbana no Brasil, entre os anos 2008 e 2018, desconsiderando outros enfoques como projeto e desenho urbano. Os resultados demonstram que existem poucas publicações nas abordagens escolhidas. A primeira delas aconteceu no ano de 2015, alcançando o maior índice no ano de 2018. A maioria na área do planejamento urbano com enfoque na conceituação do CIM aplicado ao processo de desenvolvimento da cidade e no uso de ferramentas computacionais para o planejamento baseado em dados. Na gestão urbana inferiu estudos teóricos e práticos do modelo de CIM no auxílio a gestão e crescimento sustentável. Os meios de publicações mais utilizados foram os periódicos e o evento ENANPARQ. Por fim, revela-se baixo o índice de pesquisas avançadas nestas abordagens.

Published: July 2021

Este trabalho discute a construção da narrativa de ficção televisiva sob o ponto de vista da invisibilidade da representação de personagens negros idosos. A partir do apontamento de elementos sociais e contemporâneos, analisa-se por que a temática da velhice dos negros é praticamente inexistente nas telenovelas da TV Globo. Ao se trazer aspectos da narrativa do folhetim, típica das telenovelas brasileiras, pretende-se debater de que forma é construída a anulação dos discursos de identidade a respeito de negros idosos e sua relação com aspectos da vida social.
A literatura diante de massacres cometidos pelo Estado brasileiro
Authors: Osmo Alan
Published: July 2021

Quase cem anos separam a Guerra de Canudos (1896-1897) e o massacre do Carandiru (1992). Entretanto, é possível fazer aproximações entre esses episódios marcantes da história do Brasil. Ambos foram crimes cometidos pelo Estado, a partir de ordens de governantes, e contaram com enorme aparato repressivo. Simbólico também que ambos passaram por uma tentativa por parte do Estado de um esquecimento oficial da violência cometida, por meio da destruição dos espaços palcos dos massacres: Canudos sendo inundada para fazer o açude Cocorobó em 1969, e a penitenciária do Carandiru sendo implodida para fazer o Parque da Juventude, a partir de 2002. A proposta deste trabalho é a de discutir nesses casos de massacres a importância que obras literárias tiveram em relação à memória desses crimes. No caso do Massacre de Canudos: Os sertões, de Euclides da Cunha; no caso do Massacre do Carandiru: “Diário de um detento”, de Racionais MC’s. A discussão sobre essas obras para a memória se torna ainda mais relevante quando levamos em conta que o Brasil tem sistematicamente falhado em julgar crimes cometidos pelo próprio Estado. Sem desconsiderar as diferenças significativas entre o livro de Euclides da Cunha e a canção dos Racionais MC’s, proponho discutir como a literatura foi convocada, nesses casos, a se posicionar diante da história brasileira, denunciando crimes cometidos pelo Estado que corriam, e ainda correm, o risco de serem silenciados e apagados.
O olhar sociológico de Otávio Dulci sobre a “questão regional”
Authors: Cardoso Antônio Dimas , Tibo Lucas
Published: July 2021

O objetivo deste artigo é o de refletir sobre a contribuição do sociólogo e cientista político Otávio Soares Dulci (1948-2018) na análise da “questão regional” e suas interfaces com o projeto de desenvolvimento das elites periféricas, no contexto político pós-revolução de 1930. Argumentamos que Dulci problematiza a interpretação sociológica da modernização no Brasil, tendo o estado de Minas Gerais como principal referência de investigação. Com essa discussão, o que se almeja é reconhecer o legado de Otávio Dulci para o Pensamento Social Brasileiro, não somente como analista dos cânones das Ciências Sociais produzidas no país, mas também como formulador da sociologia histórica e do desenvolvimento, que incorpora na dimensão macrossocial o conjunto de valores e ação política de grupos empresariais.
O tempo no capitalismo
Authors: Braga Henrique Pereira , Kawahara Ivan Zanatta
Published: July 2021

As transformações sociais e econômicas de grande envergadura que têm ocorrido na sociedade capitalista desde os anos de 1970 desafiam a teoria social crítica contemporânea a compreender a natureza dessa mudança e explicar seus variados desdobramentos na vida social. Esse artigo aborda uma dimensão dessa transformação: a temporalidade capitalista. Para tanto, o artigo se concentra nos argumentos de Moishe Postone sobre a natureza do tempo no capitalismo, que são elaborados a partir de sua leitura da teoria madura de Karl Marx – com especial atenção para o Grundrisse e O Capital. A conclusão dessa leitura é a de que, para Postone, a dualidade da forma mercadoria constitui uma relação entre uma dimensão temporal concreta (de valores de uso) e uma dimensão temporal abstrata (valor) que implica um específico tempo histórico que é crescentemente denso, veloz e instável.

STUDY OF THE NATURE OF OVERVOLTAGES IN THE ELECTRICAL NETWORK ARISING FROM VOLTAGE TRANSFORMERS
Authors: Hanus Oleksii , Starkov Kostiantyn
Published: July 2021

A non-linear dynamic mathematical model of voltage transformer has been considered and overvoltages arising on the elements of voltage transformer equivalent circuit during transient processes have been investigated. The influence of voltage transformer secondary circuit capacitance on overvoltage multiplicity in the primary circuits and the duration of transients has been determined. The advantages of approximation of nonlinearity of voltage transformers by hyperbolic sine are used. Mathematical expressions determining the nature of changes in the forced and free components of the transient process in an electrical network with a voltage transformer have been obtained. It is shown that with the increase of the electric network capacitance the duration of the transition process damping increases and the frequency of the forced oscillations and the level of overvoltage decrease. It is proved that even small, in comparison with the primary nominal sinusoidal voltage, aperiodic components of the voltage transient process can lead to significant overvoltages during voltage transformer outages. It has been substantiated that both the secondary resistance and the switching torque influence the overvoltage multiplicity arising in the primary winding of voltage transformers. It is shown that the closed secondary winding worsens the disconnection process of non-linear inductance of voltage transformers. The values to which overvoltages increase in this case are determined. According to the results of calculations it is determined that with open secondary winding of voltage transformers the duration of transient process significantly increases. It has been found that the decrease of frequency of forced oscillations, which occurs in this case, is accompanied by an increase of currents in the primary winding of the voltage transformer, which is dangerous in terms of thermal stability of the winding insulation. It is shown, that closing the secondary winding of voltage transformers leads to significant reduction of transient damping time. It is suggested that this algorithm can be used to provide a rapid breakdown (suppression) of ferroresonant processes. The effectiveness of such a measure of stopping of ferroresonance processes as short-term shunting of secondary winding of voltage transformers has been investigated. The correlation of parameters of electric networks (capacity of busbar sections, nonlinearity of characteristics of voltage transformers, disconnection torque, etc.) at which ferroresonance process may occur and consideration of which may allow, in terms of prevention of ferroresonance processes, to identify substations (electric networks) that require more detailed research has been determined. The results of analytical studies were tested in the electric networks of JSC "Kharkivoblenergo" and used in the electricity distribution system for the selection of specific voltage transformers for certain configurations of electrical networks.
MATHEMATICAL MODELS FOR DIAGNOSTICS OF A BOLTED CONDUCTIVE JOINT UNDER CONDITIONS OF CHANGING MODE PARAMETERS
Authors: Kryvonosov Valery , Vasylenko Serhii
Published: July 2021

The reliability of the transmission and distribution of electricity in ports, ships and energy enterprises depends on the condition of the bolted conductive joints. Operational practice shows that 2 % of cases of emergency shutdowns of technological lines and fires on electrical equipment occur due to the weakening of bolted conductive joints. The main reasons for the bolted joint weakening are dynamic changes in operating current loads and changes in climatic parameters. It is possible to increase the reliability of bolted conductive joints using modern diagnostic methods that allow identifying the appearance of bolted joint weakening. The existing methods for diagnosing the state of bolted joints, which are based on monitoring the temperature of the bolted joint, are analysed. It has been established that the use of such methods to identify the initial moment of the joint weakening is impractical, since they react to the emergency state of the bolted joint, that is, to the critical temperature value. To identify the initial moment of the bolted joint weakening, it is proposed to simultaneously monitor the values of the load current and the parameters of the ambient air, which makes it possible to increase the reliability of detecting pre-emergency situations. To diagnose the initial moment of the bolted joint weakening, it is proposed to use the estimated Boolean functions. Arguments of Boolean variables are obtained for a stationary and continuous process of changing current and ambient temperatures, a stationary and deterministic process as well as a random and deterministic process. The minimized Boolean functions are given for the normal operation of the bolted joint, when the initial moment of weakening appears and when the emergency mode occurs.
BALANSING OF POWER AND ELECTRICITY IN THE ELECTRIC POWER SYSTEM WITH RENEWABLE ENERGY SOURCES BY CRITERIONAL METHOD
Authors: Lezhniuk Petro , Buslavets Olha , Rubanenko Olena
Published: July 2021

This article considers the features of the development of renewable energy sources in electrical networks. The main changes in the functional properties of power systems, which include a significant reduction in electricity consumption, change in the structure of electricity consumption, rapid increase in the installed capacity of solar and wind power plants. Electricity consumption in 2020 is almost halved compared to 1990 (from 227 to 119 billion kWh) and as a consequence the share of semi-peak thermal generation, which gave the power system basic flexibility, has significantly decreased (from 71 % in 1990 to 35 % in 2020) and at the same time the share of nuclear generation, which operates in base mode, has increased (from 25 % to 51 %). In particular, consumption by industry with a stable load schedule, decreased (from 146 billion kWh (64 %) to 49 billion kWh (42 %)). At the same time, the demand for electricity by the households, whose consumption profile of which is characterized by significant daily unevenness and sensitivity to meteorological factors, has significantly increased (from 21 billion kWh (9 %) to 37 billion kWh (31 %)). Therefore, the article analyses the preconditions for the problem of flexible generation and explores possible ways to solve them. The optimal composition of electricity generation for Ukraine in the period 2021–2025 is proposed, which provides for the preservation and even increase by optimizing the repair campaign of the share of electricity production by nuclear power plants, the introduction of additional 2–2.5 GW of highly flexible generation and up to 2 GW storage systems (taking into account the pumped-storage power plant), as well as a gradual evolutionary decline in both installed capacity and electricity production by semi-peak coal-fired power plants and maintaining a policy of decarbonisation to ensure its own energy security. A comprehensive approach to compensating for the instability of renewable energy sources generation has been developed, which consists in minimizing the cost of power redundancy in various available ways. The problem of cost optimization for ways to compensate for the instability of renewable energy sources generation is solved by the method of criterion programming.

In Ukraine, the number of farms, private land users and protected soil structures has increased significantly in recent years. To increase the efficiency of vegetable production, small-sized mobile units in the form of motoblocks with internal combustion engines of domestic and foreign production have been widely used. However, during the operation of mobile units with internal combustion engines in greenhouses and hotbeds, the noise level and air pollution increase, which negatively affect not only people but also plants. The disadvantages of motoblocks with internal combustion engines should also include a fairly high specific consumption of liquid fuel, which has a high cost, difficulties in starting and stopping the unit, as well as the relatively low reliability of the internal combustion engine. More promising for work in protected soil structures are mobile units with traction motors, called electric motors, as environmentally friendly units that do not have these shortcomings. The main technical characteristics of the experimental sample of a small-sized electrified soil-cultivating motoblock are given in the work. The structural scheme of the power energy channel of the electric motor unit is substantiated, which clearly demonstrates the processes of energy conversion in it. The equation of energy balance of the electric motor unit and the main energy ratios that determine the properties of the traction motor in the drive of the electric motor unit are obtained. The algorithm of optimal control of a direct current traction motor by the maximum efficiency for direct current motors of serial and mixed excitation is substantiated. The results of field tests of the prototype of the electric motor unit are presented. The analysis of the obtained results of experimental researches of the electrified tillage motor-drive driven by the direct current motor of sequential excitation testifies to the reduction of specific energy consumption for the main types of tillage by 12-15%.

Community nurses have an important role in the current society. A number of roles are inherent in community nurses, among them, prevention, maintenance, health promotion and recovery of community diseases. The teenagers become one of the target of community nurses, in case of health care development. Among of them, the Narcotics, Psychotropics, and Addictive Substances (NAPZA) abuse and sex are things that need to be followed up. This can be agreed upon the case studies on Kalipucang Village, Tamantirto, Kasihan, Bantul, which show that some adolescents are involved in deviant behavior, such as drinking alcohol, drug abuse, and unexpected pregnancy –as the result of a lack of understanding of these two things. For this reason, the Youth Health Care and Potential Community Movement (GEMA PESTA REMAJA) activity be held. These activities include health screening, health education, formation and training of Youth Healthcare Services or Posyandu Remaja cadres, as well as optimizing the role of these cadres in managing the Posyandu Remaja that formed. The results of this activity showed a significant changes for the teenagers of Kalipucang Village. This can be seen from the increase in the knowledge of adolescents, which is measured through a post-test, about drug and reproductive health that they get from a series of GEMA PESTA REMAJA activities.

ABSTRAK

 

This study aims to determine the form of interference that may occur in Indonesian speakers who pronounce Javanese words with complex onset consonant clusters and to see if the interference omit the meaning of the word. This research method is to analyze the recording of the reading test by two research subjects using PRAAT software. There are two interferences produced by the research subjects, namely epenthesis schwa and deletion. The results of the perception test show that schwa epenthesis interference is unacceptable but does not omit the meaning, while deletion is unacceptable and omit the meaning. Both of these interferences are a form of adaptation of research subjects in pronouncing the complex onset consonant clusters that are not prevalent in Indonesian.
