Comparison of Methods to Detect Thermomechanical Ageing of the Insulation System for Rotating High-Voltage Machines
Authors: Elspass Lena , Schlegel Stephan , Bärnklau Hans
Published: July 2022

Increased dynamic operation of long rotating high-voltage machines as well as elevated operating temperatures lead to intensified thermomechanical stress in the insulation system of global vacuum-pressureimpregnated machines. Meanwhile, the requirements regarding reliability of the machine and the electric insulation system remain high. Consequences of thermomechanical stress include delaminations and abrasion. To satisfy the high standards of longevity, reliable diagnosis of thermomechanical ageing is essential to allow manufacturers to develop and improve countermeasures. This work identifies diagnostic tools, which investigate the effects of thermomechanical ageing on model replicates of machine insulation systems. The longitudinal thermal expansion of the conductor during dynamic operation is replicated by applying mechanical force to the conductor of specimens, thus inducing mechanical stress in the insulation system. Recurring measurements of partial discharges, dielectric losses and capacitance are evaluated regarding their sensitivity in detecting resulting ageing phenomena. The study reveals that partial discharge measurements detect preliminary damages before insulation rupture caused by mechanicalstress occurs. Knowledge of these capabilites enables future-oriented development of insulation systems for dynamically-operated long rotating machines.
Diffusion Behavior of Greases in Interfaces in Organic Insulation Materials
Authors: Höfer Lucas , Heckel Marcel
Published: July 2022

The diffusion of greases in organic insulation materials, which is the core parameter of the electrical and mechanical long-term behavior of the interface, is studied. The diffusion of grease depends both on the solid organic insulation material and on the grease. The highest diffusion can be observed by the combination of a silicone paste and silicone rubber. However, for silicone rubber there are low and no diffusion lubricants existing.The diffusion in EPDM, EP and XLPE is commonly much lower. In EP and XLPE, no type-dependency of the grease can be observed. With the knowledge of the diffusion behavior, the desired interface properties can be achieved for the whole lifespan of the apparatus.
Hybrid Method for Numerical Implementation of Segmented Power Cable Conductors in Finite-element Based Ampacity Calculation
Authors: Strand Henrik , Eberg Espen , Anders George J.
Published: July 2022

This paper addresses challenges with modelling of segmented power cable conductors using finite element analysis (FEA) for ampacity calculation. Segmented conductors improve current distribution by minimizing skin and proximity effects, thus reducing conductor losses. 2D FEA simulation offers high flexibility and accuracy beyond IEC 60287 for complex laying geometries, but the modelling of losses in segmented constructions using FEA has proven difficult due to the big difference in wire size and twisting pitch, requiring great amounts of computational power. In this paper a hybrid method is proposed, in which the IEC 60287 empirical formulae for segmented conductors are included in a 2D FEA model. The proposed method shows a good correspondence to IEC standard calculations, with deviations in conductor AC resistance of less than 1 %.
Lifetime of Oil-Impregnated Paper under Pulse Stress at Different Frequencies
Authors: Mathew Philip , Ghaffarian Niasar Mohamad
Published: July 2022

With the increasing penetration of power electronic interfaces in the power grid, insulation materials will begin to experience stresses at higher frequencies than the conventional 50 Hz AC. This article studies the lifetime curves of oil-impregnated paper (OIP) under pulsed stresses and compares them at 10 kHz and 50 kHz. A pulse modulator is constructed consisting of a rectified DC supply feeding an H-bridge pulse driver connected to a 4:200 pulse transformer. The modulator is used to apply medium voltage pulse waveforms with rise-times of Tr ≈ 1.8 µs across single-layer OIP samples. The results clearly show that an increase in pulse frequency significantly accelerates insulation ageing. However, it is also observed that below a certain threshold of field strength, the slope of the lifeline decreases dramatically thereby indicating decelerated ageing. Possible reasons for this phenomenon are also discussed in this article.

Characterization of Silicone Elastomers for Refractive Field Grading under Sinusoidal Voltages
Authors: Loh Jun Ting , Kornhuber Stefan
Published: July 2022

This contribution compares three different numerical approaches to characterize a nonlinear field dependentpermittivity when stressed with a sinusoidal voltage. Silicone elastomers with refractive field grading properties serve as test samples. Their dielectric properties such as the DC-conductivity and the complex permittivity are determined experimentally and applied to compute the numerical models. Principally, all three models apply the J-E relationship to quantify the nonlinear permittivity, different numerical methods are however implemented to solve the models. The numerical approaches are compared with experimental results and analysed. Based on the results, the most suitable numerical method to determine the nonlinear permittivity could be determined. This model serves as a fundamental approach for sinusoidal voltages and can be further adapted for non-sinusoidal voltages in the future.
Characterization of Ion Transport Properties in Synthetic Ester Oil by Polarization Current and Dielectric Spectroscopy
Authors: Cremasco Andrea , Logakis Emmanuel , Curti Mitrofan , Lomonova Elena A.
Published: July 2022

The accurate estimation of the charge carrier mobility in synthetic ester oil-based insulation systems is required for the reliable prediction of the electric field induced by dc voltages. Some discordance is observed in the literature, therefore, this quantity is investigated by two alternative methods. First, the mobility is estimated in a material sample by measuring the polarization current and the ion time-of- ight during a voltage polarity reversal test. Next, the mobility is derived from the frequency-dependent loss tangent measured by dielectric spectroscopy. The values obtained by the two methods are consistent, in the range of ≈ 2-4·10^-10 [m2/Vs] at 303 K.
Longitudinal Breakdown Strength of Wet-mate Solid-Solid Interfaces at VLF and 50 Hz AC voltages
Authors: Ildstad Erling , Dale Roger , Kantar Emre
Published: July 2022

The 50 Hz AC breakdown strength of dry interfaces is known to strongly depend upon the mechanical properties, contact pressure, roughness of the surfaces, and the type of lubricant used at the interface. This paper aims to experimentally examine how these factors affect the longitudinal AC breakdown strength of interfaces assembled in water, so-called wet interfaces. The main aim is to obtain data relevant to the design of power equipment operating at very low frequency (VLF) or DC voltages.Experiments were conducted using identical specimens made from 4mm thick plaques of PMMA and plane sections cut from XLPE cable insulation. The findings were discussed with respect to expected dimensions of interface voids and contact regions, considering tribology-based contact theory, including the impact of surface roughness, modulus of elasticity, and applied mechanical interface pressure. 

The longitudinal 50 Hz AC breakdown strength values of wet samples were typically as low as 80 % of samples assembled in the air under dry conditions. In addition, the results verified previous findings that the AC breakdown strength strongly increases with reduced surface roughness, stiffness, and increased interface pressure. The breakdown values obtained during VLF breakdown testing were found to be 2 – 3 times higher than in the case of testing at 50 Hz AC voltages.
Breakdown Voltage of Polymeric HVDC Insulation at DC Stress and Superimposed Lightning Impulse Voltages
Authors: Ildstad Erling , Mauseth Frank , Olsen Espen T.
Published: July 2022

Space charge formation makes it difficult to predict the resulting electric field distribution within HVDC cable insulation.The main purpose of the work presented here has been to experimentally study how the lightning impulse breakdown strength of thin (0.1 mm thick) insulation foils of polypropylene (PP) and Polyethylene Terephthalate (PET) are affected by DC prestress, polarity of the impulse voltage and the temperature.Tests were performed using parallel plate electrodes and prior to DC prestressing the lightning impulse breakdown strengths were found to be approximately 17.5 kV for samples of both PP and PET. Prior to superimposing lightning impulse breakdown voltages, a DC voltage of 8 kV was applied for 60 seconds. The effect of DC prestressing was to significantly increase the impulse breakdown strength during aiding and reduce the breakdown strength during opposing impulse polarity. This strongly support the assumption of homo-charge formation close to the metal electrodes during DC stress.The results showed higher and more temperature dependent charge accumulation in samples of PET. It is indicated that at 22 °C the homo-charge formed during DC stressing approximately reduced the electric field at the electrodes from 100 to 48 kV/mm in the PP samples and from 80 to 22 kV/mm in the PET samples, respectively
Improvement and uncertainty evaluation of a 1 MV lightning impulse measurement system
Authors: Aaltonen Lauri , Lahti Kari , Hällström Jari , Havunen Jussi
Published: July 2022

This paper focuses on development of an existing 1 MV lightning impulse (LI) measuring system as part of European project for i.a. LI calibration capabilities development. After carefully characterization of the original LI divider a new low voltage arm was designed and built with e.g. improved shielding and also RC circuits for compensating the detected drift in the step response. With the compensation step response was successfully corrected resulting in clear improvements in LI time parameter measurements. However, persistent high frequency noise was present in the step response complicating further fine-tuning of the response. The noise could not much be improved at least partly due to non-optimal damping resistor structure, which is difficult to improve afterwards. After the improvements an extensive uncertainty evaluation was carried out for the original system as well as for two versions of the improved system.

Published: July 2022

The Florida Canyon Zn deposit in the Bongará Province of northern Peru consists of sulfide and nonsulfide mineralizations within dolomitized strata of the Triassic Chambará Formation, a member of the Triassic-Jurassic Pucará Group. The nonsulfide mineralization, which represents one third of the total resource, formed by supergene alteration of Mississippi Valley-type sulfide bodies. The nonsulfide assemblages occur in stratabound or fault-related, discordant zones that mimic the shapes of the former sulfide zones. Two nonsulfide facies can be distinguished: facies 1 – red zinc ores, which are characterized by smithsonite, or hemimorphite-dominant bodies that formed by direct replacement of primary sulfide assemblages, and facies 2 – white zinc ores, which are characterized by masses of colloform smithsonite formed by replacement of wall rock. The facies are distinct in bulk chemical composition and stable isotope geochemistry. Facies 1 shows high concentrations of Zn, Pb, Fe, Ge, Mn, and As, whereas facies 2 shows only high Zn and Cd concentrations. Enrichments in Ge, which have been reported in other Zn deposits of the Bongará Province, are associated with hemimorphite, Fe hydroxides, and remnant sphalerite in facies 1. The δ13C and δ18O signatures of smithsonite in both facies suggest that meteoric waters infiltrating the precursor sulfide bodies were affected by kinetic fractionation and originated from multiple sources at different altitude.
PERBANDINGAN ANTARA PUISI “SAJAK JATUH CINTA” KARYA EMHA AINUN NADJIB DAN PUISI “SAJAK KECIL TENTANG CINTA” KARYA SAPARDI DJOKO DAMONO
Authors: Linati Yusrina Ayu , Wulandari Yosi
Published: July 2022

Emha Ainun Nadjib's poem "The Sajak of Falling in Love" and Sapardi Djoko Damono's "Small Poem About Love" have many similarities and contrasts, which the authors of this study try to describe. Focus will be placed on comparing the poetic structure of the two works as part of a comparative literary study. This study uses a comparative research technique. Reading, listening, taking notes, and copying were used to obtain the data in this study. After all the data is collected, the data reduction process begins. It's time to examine the data we've collected and categorize it to make a final decision about what research we're going to do next. The hypogram is found in Emha Ainun Nadjib's poem "The Poem of Falling in Love", while the transformation is found in Sapardi Djoko Damono's poem "Little Poetry About Love". The two poems have the same meaning, each of which tells about true love for the Almighty or true love for the Almighty in general. There are several similarities and differences between the two literary works, which lie in the theme, taste, tone, word and image. In addition to the similarities, there are also differences in them, namely mandate, rhyme, typography, and concrete words. Poems that have been converted into Hipograms, such as the Sajak Falling in Love by Emha Ainun Nadjib, can be compared to see how the weight of emotions can be measured and balanced with other aspects of life. This is why data analysis is currently being carried out. Sapardi Djoko Damono's Little Poem About Love, which emphasizes that one must learn to love oneself first before loving others, became the catalyst for this change.Keyword: Poetry, Comparison, Story

Published: July 2022

This study aims to determine the effects of a program based on a progressive increase in the number of nage-komi repetitions (throws) on a specific judo fitness test (SJFT). The research was conducted on a total of 20 respondents. In SJFT for research purposes, 12 variables. Descriptive statistics and paired t-tests for dependent samples of initial and final testing were used for data processing. The results of the study showed significant statistical deviations in the number of throws in the first 15 seconds, with the pulse measured immediately after testing and the SJFT index (p <005). There is a noticeable need for a table to classify SJFT results for young judoists. Based on the obtained results, we can conclude that the programmed activity had positive effects on the results of the SJFT, ie that the index was statistically significantly lower in the final than in the initial testing. Taking into account the results obtained, calculated by the SPSS 22 t-test for dependent variables, the values ??of the young judoist index and the values ??of the senior index show noticeable differences. While their results can be classified into appropriate categories, the results of young judoists can be classifieclassifiedrity, under, ad and the rest as very bad. Some results could not even be ranked, so we conclude that it is necessary to make tables for classifying the results of young judoists. The obtained results can be used as guidelines for more efficient programming of the training process.

Dental Anxiety - Definition, Etiology, Diagnosis and Treatment Options
Authors: Mantesso Andrea
Published: July 2022

Dental anxiety is a common condition that can lead to dental avoidance behavior. As such, the oral health of patients suffering from dental anxiety typically deteriorates over time resulting in costly treatments and complex procedures that could had been avoided, prevented, and treated while they were simple and easy to care for. Dental anxiety is commonly misdiagnosed, has been linked to different etiological factors, and can manifest at any time in an individual’s life. Identification of this condition is simple and can be routinely done using short, standardized surveys. In addition, there are many efficient and cost-effective options to treat or alleviate this condition. However, dentists and other oral health practitioners such as dental hygienists and dental assistants, are usually unaware of how to identify and address dental anxiety during dental care. Thus, herein we reviewed the literature about definitions of dental anxiety and associated conditions such as dental fear and dental phobia. Furthermore, we discuss possible etiologies and how to effectively diagnose this condition. Finally, we present possible treatment options available for dentists and other dental care providers to safely care for dental patients suffering from dental anxiety

Resisting renovictions: tenants organizing against housing companies’ renewal practices in Sweden
Authors: Polanska Dominika V. , Richard Åse
Published: July 2022

While governing practices, as articulated in policies and other documents intended to shape tenants’ behavior, have been given considerable attention in research, less attention has been given to the self-regulation of tenants in practice or how these governance practices are challenged and resisted from below. The ambition of our work is to study governing practices deployed by housing companies in two Swedish cities to achieve tenants’ compliance with extensive housing renewal plans, and to conceptualize this means of exerting power as practices through which tenants are governed, silenced and surveilled, and their collective interests divided. Building on several years of ethnographic work among communities of tenants experiencing extensive renovation of their homes and, in particular, qualitative interviews and focus-group interviews with tenants, this study analyzes how governing practices are exercised by housing companies and contested by tenants. Our contribution is twofold: First, we propose the broadening of the notion of repertoires of contention alongside collectively organized contention to include covert and individual forms of resistance. We understand these forms as mutually shaping, and distinguish between eight forms of resistance repertoires common among tenants facing renovictions (indirect evictions caused by extensive housing renewal and skyrocketing rents) in Sweden: building local identities, mixing formal and informal forms of organization, delaying the process, detournement, politics of disengagement, demanding accountability through visibility, reversing knowledge hierarchies, and reversed shaming. Second, we aim to add to the still understudied field of tenants’ mobilizations in the Swedish context.
PANDEMİ AŞILARI VE İLAÇLARINDA PATENT KORUMASININ DEĞERLENDİRİLMESİ

Published: July 2022

COVID-19 salgını, Dünya Sağlık Örgütü (DSÖ) tarafından 11 Mart 2020 tarihinde dünya çapında bir salgın (küresel pandemi) olarak duyuruldu. DSÖ, bu duyuru ile ülkeleri, salgının küresel ekonomide ve sağlıkta benzeri görülmemiş bir krizi temsil ettiği konusunda uyardı. Her ne kadar ülkeler çeşitli seviyelerde almış oldukları sokağa çıkma yasakları, dönüşümlü ya da evden çalışma, sınırların kapatılması ya da yabancılara karantina uygulanması gibi kısıtlama ve tedbirlerle salgını önlemeye çalışsalar da bu tedbirlerin çok da işe yaradığı söylenemez. Zira alınan tedbirler salgını sona erdirmeyip sadece süreci yavaşlatmaktadır. Salgının bir süre daha devam etmesi halinde ise sonucu en başta fiziksel ve psikolojik olarak insan sağlığını etkileyecek; bununla da sınırlı kalmayıp ekonomi, sanayi, eğitim ve turizm gibi alanlarda telafisi yıllarca mümkün olmayacak zararlara sebebiyet verecektir. 2020 yılı başlarında kısa bir süre içerisinde dünyayı etkisi altına almasına rağmen etkisini uzun süredir devam ettiren COVID-19 salgınını önleyebilmek için şu an elimizde bulunan en etkili ilaç COVID-19 aşılarıdır. Aralık 2020 sonu itibarıyla aşıya erişebilen ülkelerde öncelikli gruplardan başlanmak üzere aşılama başlamıştır. 18 Temmuz 2021 tarihi itibariyle dünya genelinde 3.66 milyar doz aşı yapıldığı görülmektedir. Bazı ülkeler iki doz aşı hedefine ulaşmaya çalışırken ülkemizde de olduğu gibi bazı bölgelerde üçüncü doz aşılamaya geçmişlerdir. Yemen, Mali gibi ülkelerde bu oran oldukça düşükken Haiti gibi bazı gelişmemiş ülkelerde ise henüz tek doz dahi aşı uygulanmamıştır. Koronavirüsün hızlı mutasyon geçiren yapısı göz önünde bulundurulduğunda dünya genelinde eş zamanda aşılama uygulanmadan salgının bitmeyeceği ve sektörler üzerindeki olumsuz etkisini daha yıllarca sürdüreceği ortadadır. Bu nedenle Dünya Ticaret Örgütü ve bazı dünya liderlerinin açıklamalarıyla birlikte COVID-19 aşıları ve tedavileri için ilaç şirketlerinin patent yükümlülüklerinden feragat etmesinin mümkün olup olmayacağı hususunda tartışmalar gündeme gelmiştir. Zira, içinde bulunduğumuz bu olağanüstü dönemde TRIPS Anlaşması kapsamında patent hakkının ilaç şirketlerine sağlamış olduğu yasal koruma ile insanların temel haklarından olan ilaçlara erişim hakkı arasında bir denge kurulması gerekmektedir. Bu çalışmada, COVID-19 aşı ve ilaçlarından patent korumasının kaldırıp kaldırılamayacağı hususu benzer örnekler dikkate alınarak analiz edilecektir.

Salah satunya yaitu kawasan mangrove yang ada di sepanjang pesisir Desa Aeramo dan Desa Marapokot, Kecamatan Aesesa, Kabupaten Nagekeo, NTT yang belum terkelola dengan baik. Tujuan penelitian ini yaitu menganalisis kesesuaian dan daya dukung kawasan mangrove untuk kegiatan ekowisata. Penelitian ini dilakukan pada bulan September 2021 di kawasan mangrove Kecamatan Aesesa, yaitu di Desa Marapokot dan Aeramo. Terdapat lima parameter kesesuaian sumber daya yang diukur, yaitu ketebalan mangrove, kerapatan mangrove, jenis mangrove, pasang surut, dan objek biota. Kawasan mangrove di Marapokot belum sesuai untuk dimanfaatkan sebagai kawasan ekowisata karena ketebalan mangrove yang rendah. Sementara kawasan mangrove di Aeramo belum sesuai untuk kegiatan ekowisata karena jenis mangrove yang tumbuh bernilai rendah. Potensi daya dukung kawasan mangrove untuk kegiatan ekowisata Marapokot 840 orang/hari, sedangkan di Aeramo 764 orang/hari, yang terdiri atas empat trip setiap harinya. Pengembangan ekosistem mangrove untuk menjadi kawasan ekowisata sangat membutuhkan perhatian khusus dari masyarakat setempat dan pemerintah daerah.
Quantitative Courses in Higher Education: A Comparison Between Asynchronous and Synchronous Distance Learning
Authors: Ghilay Yaron
Published: July 2022

Quantitative courses in higher education have always been difficult and demanding because they involve complex principles and procedures and students are required to deal with complicated problems. With the outbreak of the COVID-19 crisis and the need to move immediately to distance learning, the challenge involved in undertaking such courses has become even more significant.

Recent studies point to different findings regarding the effect of asynchronous and synchronous learning on student performance so it is not entirely clear which method is preferable. The present study addresses the above ambiguity with a focus on quantitative courses, known for their special complexity. The study examined which method is preferable and why, based on the learners’ point of view. Two main issues were examined: the contribution of each method to the learning process and whether one of them is significantly superior to the other and can even replace it exclusively.

The research was based on two samples of students  who enrolled in eight quantitative courses at two colleges. The courses were given during the year 2020-2021 using combined teaching formats: Asynchronous and synchronous distance learning. Learners were asked to answer an online questionnaire that assessed the characteristics and advantages/disadvantages of both methods.

The findings show that students distinctly prefer asynchronous learning over synchronous. The main reasons for this are the ability to repeat lessons indefinitely, time savings, flexible learning anywhere, anytime and at the appropriate pace as well as the ability to better understand the material.

Participants in this international intercomparison exercise performed from June 26th to June 30 th were seven measuring teams of the Czech Republic, Germany, France and Switzerland. In advance to the intercomparison exercise, two measuring areas around the nuclear power plants Gösgen and Mühleberg were inspected by Swiss teams CH01 and CH02 on June 22nd and June 23rd following a bi-annual schedule on behalf of the Swiss nuclear safety inspectorate (ENSI). No artificial radionuclides were detected outside the premises of the power plants. The main measurement task for the international exercise tried to simulate a scenario in which the deployment of airborne gamma-spectrometry is essential and international support would be requested. The scenario assumes a theft of a strong radioactive 137Cssource. The get-away car including the empty source shielding was found abandoned by the police, suggesting that the thieves took flight on foot taking the source with them. Police investigations determined a perimeter inside which the thieves and the source should be located. The associated area adds up to seven percent of Switzerland (2900 km2). Two 137Cs-sources were placed in the search area. Both sources were identified and located during the exercise. Additional tasks consisted in combining the measured data in the source search area into composite maps of the natural radioactivity and in several reference areas for a direct comparison of system performance. The results of the measurements showed some minor differences between the results of the measuring teams. Several supplementary tasks were included into the exercise to provide informations for potential optimisation of data evaluation to the participants. An altitude profile over a Swiss lake yielded information on system background and the influence of cosmic radiation. A reference area with mainly flat topography measured prior to the exercise with in-situ gammaspectrometry on the ground by staff of the Nuclear Biological Chemical - Explosive Ordnance Disposal (NBC-EOD) Centre of Competence was introduced to check on individual calibration factors and the influence of different ground clearances on the measurement results. A second reference area with alpine topography and a transversal going from flat to alpine terrain was introduced to provide information on the influence of topography on the measurement results. The detailed analysis of the results of the supplementary tasks in combination with post-processing of raw data after the exercise helped to reduce some of the differences in the composite mapping observed during the exercise.

The measurement flights of the exercise ARM16 were performed between June 27th and July 1st, 2016. The exercise was organized by the National Emergency Operations Centre (NEOC) under coordination from the Expert Group for Aeroradiometrics (FAR). Representatives of KompZen ABC-Kamir participated with a second Super Puma helicopter carrying the prototype of a new airborne gamma-spectroscopy system (RLL) in parts of the exercise. According to the alternating schedule of the annual ARM exercises, the environs of the nuclear power plants Beznau (KKB) and Leibstadt (KKL) and the nuclear facilities of the Paul Scherrer Institute (PSI) and the Zwischenlager Würenlingen AG (Zwilag) were surveyed. Both reactor blocks of KKB were in maintenance shutdown during the flights. The series of radiological background measurements over Swiss cities was complemented with measurements over Luzern, Emmen, Cham, Baar and Zug. A permanent dose rate probe of the Swiss NADAM Network near Vicosoprano measures the highest values observed in this network. The vicinity of the probe was inspected with airborne gamma-spectrometry and the elevated dose rate was confirmed and could be attributed to elevated concentrations of natural radionuclides. The emergency exercise LAURA, consisting mainly of the search for radioactive sources, was conducted at Emmen military airfield in cooperation with local first responders. Several measuring flights were performed to test the evaluation procedures. Especially the parameters for background and altitude corrections were inspected.

The COVID-19 pandemic has disrupted the whole world, causing many social and economic issues. In particular, at the initial stage of the pandemic, the above-mentioned issues were more acute; urgent measures had to be developed and implemented at the state level. In order to restrain the rate of the pandemic, the government adopted a number of economic and transport laws and decisions imposing other restrictions. In consequence of that, sharp fluctuations were observed in the RA labor market. Especially during the early stages of the pandemic, many employees lost their jobs or started working fewer hours. Labor market indicators have started to show some irregular changes. Hence, the arising issues led to accepting several coronavirus mitigation measures in order to reduce the result of coronavirus, especially a large group of events was directed to reduce the social impact of problems in the labor market, especially for those who have lost their jobs. This study has examined the dynamics of changes in the leading indicators characterizing the RA labor market, their relationship with the outbreak waves, and the nature of measures to neutralize the effects of the pandemic since 2019.
