Authors: Lopes Juliano Pinheiro , De Freitas André Everton , Damasceno Vinícius Oliveira , Cristina Moreira Damázio Laila , Lamounier Joel Alves
Published: March 2021

No Brasil, a obesidade é um dos mais alarmantes problemas nutricionais na infância e vida adulta. O objetivo deste trabalho foi caracterizar a postura dos membros inferiores de crianças de 6 a 9 anos, comparando os resultados das crianças eutróficas com as obesas. Inicialmente as medidas de peso e altura foram feitas para determinação do índice de massa corporal; a avaliação postural foi realizada com fotografias digitais e com o auxílio do programa Corel Draw 10. Nos joelhos valgos, foram observadas as distâncias intermaleolares, e calculado o ângulo Q, para determinação dos alunos com alterações de valgismo do joelho. A avaliação dos pés planos foi realizada através da sua impressão no pedígrafo e posteriormente, realizado o cálculo do índice de Schipaux-Smirak para a determinação destas alterações. As análises estatísticas foram realizadas utilizando o software Stata, através dos testes de qui-quadrado, exato de Fischer, Kruskal-Wallis, considerando um nível de significância de p<0,05. Foram avaliadas 708 crianças, sendo 46,8% do sexo masculino e 53,2% feminino. Destas, 77,4% estavam eutróficas, 17% com sobrepeso e 5,7% obesas. A idade média das crianças foi de 7,7 ± 1,0. O índice de massa corporal médio foi de 17,0 ± 2,9. Foi identificado diferença significativa entre os grupos nas variáveis relacionadas aos pés planos e a idade da criança. Conclui-se que a  obesidade infantil deve ser combatida para evitar complicações futuras, inclusive ortopédicas. Não se sabe ao certo quando a formação do arco plantar acontece, mas a obesidade quando não favorece o rebaixamento deste arco, atrasa seu desenvolvimento.

Published: March 2021

Mulheres grávidas vivenciam situações nem sempre positivas que, por vezes, são marcadas por violações de seus direitos sexuais e reprodutivos. O objetivo deste trabalho foi identificar situações de violência obstétrica (VO) a partir de vivências de mulheres em trabalho de parto, parto e puerpério. O método utilizado foi à pesquisa descritiva, exploratória de abordagem qualitativa, realizada em maternidades públicas, nas cidades de Petrolina, Pernambuco e Juazeiro, Bahia. Os dados foram coletados através de entrevista semiestruturada e analisados conforme a técnica de Análise de Conteúdo Temático. Foram identificadas situações de VO em que se pode observar problemas organizacionais como reflexo do abuso e desrespeito das instituições, como demora no atendimento, restrição alimentar, problemas de infraestrutura e peregrinação. Além disso, as experiências vivenciadas foram permeadas por entraves na humanização da assistência, em que foi violado o direito das mulheres a uma assistência de qualidade e humanizada. Pode-se perceber também o não reconhecimento da VO pelas parturientes. Conclui-se que é notória a necessidade de estabelecimento de novas práticas nessas instituições com estratégias de reestruturação do atendimento para melhoria na assistência materno-infantil frente ao combate a violência obstétrica.

Authors: Pradeesh Arumugam , Vasudevan Biju , Sharma Nitu , Verma Rajesh
Published: March 2021

A 48-year-old diabetic man presented with complaints of acute onset chest heaviness with palpitations, anxiety and headache. He had raised troponin-T level and electrocardiogram showed ST elevation myocardial infarction. There was a prior history of fever of 4 days duration with associated abdominal pain. He later developed skin rash and neurological symptoms following admission to the hospital. Dermatological examination revealed purpura and a livedo-like rash. Investigations revealed deranged liver and renal function tests and positive serological tests for scrub typhus. Coronary angiography revealed no evidence of atherosclerosis or any other pathology. He was therefore diagnosed as a case of scrub typhus-induced vasculitis with coronary manifestations and was managed with oral doxycycline. Scrub typhus presenting like an acute coronary syndrome has been reported very rarely previously. In addition, patient had gastrointestinal, central nervous system and hematological involvement which added to the rarity of the case.
Development of a novel loop-mediated isothermal amplification assay for rapid detection of Mycobacterium leprae in clinical samples
Authors: Joshi Shweta , Sharma Vanila , Ramesh V. , Singh Ruchi , Salotra Poonam
Published: March 2021

Background:

Sensitive and definitive diagnostic tests are required for timely treatment of leprosy and to control its transmission.

Aim:

In the present study, we report the development of loop-mediated isothermal amplification assay using six primers targeting the RLEP gene sequence uniquely present in Mycobacterium leprae.

Methods:

Tissue punch samples (n = 50) and slit aspirates (n = 50) from confirmed cases of leprosy (M. leprae positive by quantitative polymerase chain reaction), reporting at the Department of Dermatology, Safdarjung Hospital, New Delhi, were analyzed using newly developed closed tube loop-mediated isothermal amplification assay. The sensitivity and specificity; positive predictive value, negative predictive value and accuracy were calculated using MedCalc statistical software.

Results:

The loop-mediated isothermal amplification assay specifically amplified M. leprae genomic DNA with an analytical sensitivity of 100 fg. About 47 Out of the 50 quantitative polymerase chain reactions confirmed M. leprae positive tissue samples, 47 were positive by loop-mediated isothermal amplification assay (sensitivity 94%; 95% confidence interval 83.5%–98.8%) while only 31/50 were positive by histopathology (sensitivity 62%; 95% confidence interval 47.2%–75.4%). Using slit aspirate samples of these 50 patients, 42 were positive by both quantitative polymerase chain reaction and loop-mediated isothermal amplification assay (sensitivity 84%; 95% confidence interval 70.9%–92.8%) while only 23/50 (sensitivity 46%; 95% confidence interval 31.8%–60.7%) were positive by microscopy.

Limitations:

In the present study, the leprosy patient cohort was not uniform, as it comprised of a lower number of paucibacillary cases (22%) compared to multibacillary (78%) cases.

Conclusion:

Loop-mediated isothermal amplification assay established here provides a rapid and accurate diagnostic test for leprosy in terms of sensitivity and specificity. The assay is simple to perform in comparison with other molecular techniques (polymerase chain reaction/quantitative polymerase chain reaction) and has potential for field applicability.
Association between erythema nodosum/erythema induratum of Bazin and Mycobacterium tuberculosis infection in Koreans
Authors: Kim Kang Su , Kim Jae Seok , Kim Sang Seok , Kim Chul Woo
Published: March 2021

Background:

Erythema nodosum and erythema induratum of Bazin are similar inflammatory diseases of the lower extremities. These are clinically distinguishable entities, though overlap can occur. Both diseases are reported to be related to Mycobacterium tuberculosis infection, but it is very difficult to identify Mycobacterium tuberculosis in skin lesions.

Aim:

This study aimed to develop a new nested polymerase chain reaction targeting the IS6110 insertion sequence of M. tuberculosis to improve the M. tuberculosis detection rate in skin lesions of erythema nodosum or erythema induratum of Bazin.

Methods:

From May 2016 to Jan 2018, 14 patients with clinically suspicious erythema nodosum or erythema induratum were enrolled in the study. Two cases were classified as erythema nodosum and 12 as erythema induratum. Individual patients were subjected to a 4-mm punch biopsy, and their venous whole blood was sampled immediately after diagnosis.

Results:

Eight patients were tested for M. tuberculosis using QuantiFERON, of which seven (87.5%) were positive. IS6110-nested polymerase chain reaction on all 14 patients identified 11 (78.6%) positive cases. Four of the eight (50%) individuals tested with QuantiFERON were also positive in the IS6110 nested polymerase chain reaction. The difference between the outcomes of the QuantiFERON and the IS6110-nested polymerase chain reaction tests was not statistically significant. There was also no significant agreement between the results of both assays. Sequencing the IS6110-nested polymerase chain reaction products showed a 97%–100% nucleotide sequence identity with the H37Rv genome.

Conclusion:

It is important to test for tuberculosis in patients with multiple tender subcutaneous nodules on their lower extremities in high-burden tuberculosis countries like Korea.

Limitations:

We need to register more suspicious patients to verify the association between erythema nodosum/erythema induratum of Bazin and M. tuberculosis. Furthermore, it is necessary to improve the more sensitive polymerase chain reaction technique to identify M. tuberculosis directly in cutaneous lesions.

Introduction: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) that began in Wuhan (China), that spread rapidly worldwide, seriously affecting the population leading to a public health emergency declared by the World Health Organization. It is unknown how SARS-CoV-2 infection can affect thyroid function. In this study, we describe the characteristics of an unusual analytical interference that may explain the false detection of hypothyroidism in patients with SARS-CoV-2 infection. This is the first time that a phenomenon of this nature has been described in patients with COVID-19 and underlying thyroid dysfunction. Material and Methods: Observational study of patients admitted for severe COVID-19 infection and underlying thyroid disease. Results: TSH levels presented an atypical pattern different from that of Euthyroid Sick Syndrome (ESS), confirmed by the lack of response to substitution treatment. We develop different studies to confirm or eliminate potential interferences, being diagnosed of a possible macro-TSH. Conclusion: It is important to consider that in patients with COVID-19 and high concentrations of TSH and thyroid hormones within reference ranges with lack of response to treatment, one of the possible causes to consider is the presence of macro-TSH. The presence of macro-TSH interference in COVID-19 patients requires extreme precautions to avoid errors in diagnosis or treatment (replacement dose adjustment) in patients with hypothyroidism secondary to an underlying disease.
Fast and efficient exact synthesis of single-qubit unitaries generated by Clifford and T gates
Authors: Kliuchnikov Vadym , Maslov Dmitri , Mosca Michele
Published: March 2021

In this paper, we show the equivalence of the set of unitaries computable by the circuits over the Clifford and T library and the set of unitaries over the ring $\mathbb{Z}[\frac{1}{\sqrt{2}},i]$, in the single-qubit case. We report an efficient synthesis algorithm, with an exact optimality guarantee on the number of Hadamard gates used. We conjecture that the equivalence of the sets of unitaries implementable by circuits over the Clifford and T library and unitaries over the ring $\mathbb{Z}[\frac{1}{\sqrt{2}},i]$ holds in the $n$-qubit case.
Entanglement distillation by extendible maps
Authors: Pankowski Lukasz , Brandao Fernando G.S.L. , Horodecki Michal , Smith Graeme
Published: March 2021

It is known that from entangled states that have positive partial transpose it is not possible to distill maximally entangled states by local operations and classical communication (LOCC). A long-standing open question is whether maximally entangled states can be distilled from every state with a non-positive partial transpose. In this paper we study a possible approach to the question consisting of enlarging the class of operations allowed. Namely, instead of LOCC operations we consider $k$-extendible operations, defined as maps whose Choi-Jamio\l{}kowski state is $k$-extendible. We find that this class is unexpectedly powerful - e.g. it is capable of distilling EPR pairs even from completely product states. We also perform numerical studies of distillation of Werner states by those maps, which show that if we raise the extension index $k$ simultaneously with the number of copies of the state, then the class of $k$-extendible operations are not that powerful anymore and provide a better approximation to the set of LOCC operations.
Optimal asymmetric quantum cloning for quantum information and computation
Authors: Kay Alastair , Ramanathan Ravishankar , Kaszlikowski Dagomir
Published: March 2021

While the no-cloning theorem, which forbids the perfect copying of quantum states, is well-known as one of the defining features of quantum mechanics, the question of how well the theory allows a state to be cloned is yet to be completely solved. In this paper, rigorous solutions to the problem of $M\rightarrow N$ asymmetric cloning of qudits are obtained in a number of interesting cases. The central result is the solution to the $1 \rightarrow N$ universal asymmetric qudit cloning problem for which the exact trade-off in the fidelities of the clones for every $N$ and $d$ is derived. Analogous results are proven for qubits when $M=N-1$. We also consider state-dependent $1 \rightarrow N$ qubit cloning, providing a general parametrization in terms of a Heisenberg star Hamiltonian. In all instances, we determine the feasibility of implementing the cloning economically, i.e., without an ancilla, and determine the dimension of the ancilla when an economic implementation is not possible.
Effects of quantum error correction on entanglement sudden death
Authors: Yonac Muhammed , Eberly Joseph H.
Published: March 2021

We investigate the effects of error correction on non-local quantum coherence as a function of time, extending the study by Sainz and Bjork. We consider error correction of amplitude damping, pure phase damping and combinations of amplitude and phase damping as they affect both fidelity and quantum entanglement. Initial two-qubit entanglement is encoded in arbitrary real superpositions of both $\Phi$-type and $\Psi$-type Bell states. Our main focus is on the possibility of delay or prevention of ESD (early stage decoherence, or entanglement sudden death). We obtain the onset times for ESD as a function of the state-superposition mixing angle. Error correction affects entanglement and fidelity differently, and we exhibit initial entangled states for which error correction increases fidelity but decreases entanglement, and vice versa.
Many-to-one remote information concentration for qudits and multipartite entanglement
Authors: Wang Xin-Wen , Tang Shi-Qing , Xie Li-Jun , Zhang Deng-Yu , Kuang Le-Man
Published: March 2021

Telecloning and its reverse process, referred to as remote information concentration (RIC), have attracted considerable interest because of their potential applications in quantum-information processing. We here present a general scheme for RIC in $d$-level systems (qudits), in which the quantum information initially distributed in many spatially separated qudits can be remotely and deterministically concentrated to a single qudit via an entangled channel without performing any global operations. We show that the entangled channel of RIC can be different types of entangled states, including mixed states as well as pure ones. More interestingly, these mixed states include a bound entangled state which has a similar form to the generalized Smolin state but has different characteristics from it. We also show that there exists a multipartite entangled state which can be used to implement both telecloning and RIC in the two-level system. Our many-to-one RIC protocol could be slightly modified to perform some types of many-to-many RIC tasks.
Can quantum entanglement implement classical correlated equilibria?
Authors: Deckelbaum Alan
Published: March 2021

We ask whether players of a classical game can partition a pure quantum state to implement classical correlated equilibrium distributions. The main contribution of this work is an impossibility result: we provide an example of a classical correlated equilibrium that cannot be securely implemented without useful information leaking outside the system. We study the model where players of a classical complete information game initially share an entangled pure quantum state. Players may perform arbitrary local operations on their subsystems, but no direct communication (either quantum or classical) is allowed. We explain why, for the purpose of implementing classical correlated equilibria, it is desirable to restrict the initial state to be pure and to restrict communication. In this framework, we define the concept of pure quantum correlated equilibrium (PQCE) and show that in a normal form game, any outcome distribution implementable by a PQCE can also be implemented by a classical correlated equilibrium (CE), but that the converse is false. We extend our analysis to extensive form games, and compare the power of PQCE to extensive form classical correlated equilibria (EFCE) and immediate-revelation extensive form correlated equilibria (IR-EFCE).
Fabrication and Nanoscale Properties of PEDOT:PSS Conducting Polymer Nanospheres
Authors: Sanviti Matteo , Alegria Angel , Martínez-Tong Daniel E
Published: March 2021

Electrically conducting nanospheres of poly-(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) with tailored size, were prepared by a one-step method. To fabricate the nanostructures, PEDOT:PSS was dissolved in ethylene glycol using a novel strategy and the solution was precipitated in deionized water. The proposed fabrication route allowed to obtain a water-based dispersion of monodisperse nanospheres with good optical properties. To determine physical properties of the nanospheres, we followed a nanoscale approach, using Atomic Force Microscopy (AFM). Our nanoscale mechanical and electrical investigations showed that the nanospheres preserved good physical properties, compared to the commercial product. Moreover, the local studies indicated that the confinement imposed by the spherical shape can lead into a different arrangement of the PSS and PEDOT phases. In particular, we envisaged nanospheres composed by a PEDOT-rich surface, responsible for the good electrical conductivity of the nanostructures.

The Convergence Between Cultural Psychology and Developmental Science: Acculturation as an Exemplar
Authors: Schwartz SJ , Szabo Agnes , Meca A , Ward Colleen , Martinez CR , Cobb CL , Benet-Martínez V , Unger JB , Pantea N
Published: March 2021

© Copyright © 2020 Schwartz, Szabó, Meca, Ward, Martinez, Cobb, Benet-Martínez, Unger and Pantea. The present article proposes an integration between cultural psychology and developmental science. Such an integration would draw on the cultural-psychology principle of culture–psyche interactions, as well as on the developmental-science principle of person↔context relations. Our proposed integration centers on acculturation, which is inherently both cultural and developmental. Specifically, we propose that acculturation is governed by specific transactions between the individual and the cultural context, and that different types of international migrants (e.g., legal immigrants, undocumented immigrants, refugees, asylum seekers, crisis migrants) encounter quite different culture–psyche interactions and person↔context relations. We outline the ways in which various acculturation-related phenomena, such as acculturation operating at macro-level versus micro-level time scales, can be viewed through cultural and developmental lenses. The article concludes with future directions in research on acculturation as an intersection of cultural and developmental processes.
Testing the construct validity and empirical distinctiveness of the Multicultural Identity Styles Scale (MISS) and the bicultural identity integration scale (BIIS-2)
Authors: Szabo Agnes , Ward Colleen , Meca A , Schwartz SJ
Published: March 2021

© 2020 American Psychological Association. The Bicultural Identity Integration Scale (BIIS-2) and the Multicultural Identity Styles Scale (MISS) were designed to assess different aspects of bicultural identity. The BIIS-2 captures characteristics of a bicultural identity in the domains of affect (harmony vs. conflict) and cognition (blendedness vs. compartmentalization). The MISS measures 2 distinct strategies (hybrid and alternating identity styles) used to achieve and maintain a bicultural identity. The aims of the present study were to investigate the factor structures of MISS and BIIS-2 scores using confirmatory factor analysis and to examine potential construct overlap between the 2 measures using exploratory structural equation modeling. Measures were administered twice (11 days apart) to a sample of 836 Hispanic young adults in the United States. Confirmatory factor analytic results supported the 2-factor structure of the MISS. The BIIS-2 items patterned onto 4 factors: harmony, conflict, blendedness, and compartmentalization. Configural, metric, and scalar equivalence of the factor structures of both measures were established across time. The exploratory structural equation modeling indicated no salient cross-loadings between the MISS and the BIIS-2 subscales, and this independence was consistent across time. Interfactor correlations indicated a strong, positive relationship between the hybrid identity style and BII-blendedness subscales. Scores on the alternating identity style subscale were positively related to the BII-conflict, BII-compartmentalization, and BII-blendedness subscales. Overall, findings provide evidence for the construct validity of the MISS and its empirical distinctiveness from the BIIS-2 and suggest a 4-factor structure for the BIIS-2. The study suggests that the Multicultural Identity Styles Scale and the Bicultural Identity Integration Scale assess distinct aspects of a bicultural identity. Additionally, findings confirm the construct validity of the Multicultural Identity Styles Scale with a sample of Hispanic young adults and indicate a potential four-factor structure for the Bicultural Identity Integration Scale.
A rare case of adult ileo-colic intussusception: Hamartomatous polyp as a lead point with concurrent appendiceal neurofibroma in Neurofibromatosis Type 1
Authors:   1Department of General Surgery, The Canberra Hospital, Yamba Drive, GARRAN, Australian Capital Territory 2605.
Published: March 2021

Intussusception is a rare cause of adult intestinal obstruction and unlike in children, adult intussusception is commonly caused by a lead point, requiring surgical intervention in most cases. Hamartomatous polyp is a non-neoplastic growth of tissue containing mature cells, distributed in an abnormal manner. It is often associated with intestinal polyposis syndromes such as Peutz-Jeghers syndrome and Juvenile polyposis. In the current case, we report an extremely rare case of ileo-colic intussusception secondary to a lead point of an isolated ileal hamartomatous polyp in an elderly gentleman with Neurofibromatosis type-1. Patient was successfully treated with ileo-colic resection involving the intussuscepted segment of bowel. There was an incidental finding of a nodule in the appendix and the histology confirmed this as a neurofibroma. Post-operative recovery of the patient was unremarkable.

The third volume ("Paradigms") contains general discussion on programming paradigms as a concept; object-oriented programming and abstract data types illustrated with C++; a part devoted to "immutable" computations, which introduces Lisp, Scheme, Prolog and illustrates lazy evaluations using the Hope language. The last part of the book discusses compiled and interpreted execution models as a special kind of programming paradigms; Tcl is used as an example of fully-interpreted language; Ousterhout's dichotomy is defined and explained.
Experts' Perceptions of Water Security in Central Asia: results from a Delphi study
Authors: Assubayeva Aliya
Published: March 2021

Water security in Central Asia has been discussed by researchers and international organizations using hydrological, engineering, and modeling approaches. Various frameworks conceptualize water security through technical, socio-economic, and environmental aspects. This study attempts to identify the current trends of perceptions of experts about water security in Central Asian countries and Afghanistan as assessed through different regional and international experts with relevant knowledge and experience. The experts originate from diverse professional backgrounds like ministries, NGOs, international organizations, research, and academic institutes. The analysis was conducted through the Delphi approach, which has been widely used to identify experts' views by reaching a consensus on various subjects. The Delphi method assisted in the elicitation of experts' opinions about different water security dimensions in the overall region and each Central Asia country that have been suggested from the relevant literature. The two-round questionnaire was developed to infer the experts' views (round 1) on water security in Central Asia and then identify the agreement's rate with the initial findings (round 2). The results have shown that, while the relevant scientific literature gives priority to environmental factors, the experts emphasize water security's economic aspects. Experts suggested including transboundary challenges, legislative and institutional weaknesses in assessing water security in Central Asia and Afghanistan. Respondents highlighted the low effectiveness or ineffectiveness of the current institutions and mechanisms that dealt with water security-related issues in Central Asia and suggested strengthening water governance in the region.

Published: March 2021

Introduction: Gynecomastia (GM) is a benign proliferation of glandular breast tissue in men. Some cases need surgical intervention. Traditional open surgery by semicircular inferior periareolar incision is the most common surgical approach. In order to obtain better esthetic results, some alternatives to open surgery have been proposed, such as liposuction, endoscopic mastectomy, and vacuum-assisted excision (VAE). Objective: To describe the technical surgical approach of ultrasound-guided VAE of GM and its results from a case series. Method: This is an evaluation of seven GM cases submitted to ultrasound-guided VAE with a 10G needle using the ENCOR® BD whole circumference automated breast biopsy system in Redimasto – Redimama, a Brazilian breast center. The result was considered good or satisfactory when it showed minimal remaining gland, good symmetry, no retraction, necrosis, hypertrophic scar, or displacement of the nipple-areola complex. All patients answered a questionnaire to evaluate their satisfaction and perception of the procedure. Results: Seven (7) patients with Simon grade 1 and 2 bilateral GM underwent ultrasound-guided VAE. No case of displacement, necrosis, or retraction of the nipple-areola complex, post-procedure bleeding, infection, skin necrosis, or asymmetry was detected. No patient reported decrease or change in nipple sensation or erection. All patients had bruises and hematomas that spontaneously resolved within 30 days. All results were considered good or excellent by patients and surgeons. Conclusion: Minimally invasive ultrasound-guided VAE is an excellent alternative for the treatment of GM. It is better indicated for Simon grade 1 and 2 GM, with good and excellent esthetic results, small scar, and low rates of nipple and areolar complications. It allows an outpatient procedure with low morbidity (local anesthesia) and fast recovery.

El crecimiento de los pinos en suelos erosionados es limitado, por la existencia de poca materia orgánica. Conocer el crecimiento de diferentes procedencias de una especie en suelos degradados permite entender su adaptabilidad, lo que favorece la toma de decisiones en reforestaciones posteriores. El objetivo del presente trabajo fue conocer el crecimiento de 13 procedencias de Pinus greggii var. greggii y Pinus greggii var. australis establecidas en suelos erosionados de dos localidades de la Mixteca Alta de Oaxaca. Se midió la altura, diámetro normal, diámetro basal y diámetro de copa en tres árboles centrales por cada unidad experimental de 3 × 3; se utilizó un diseño de 12 boques completos al azar. Se realizó un ANOVA y prueba de Tukey con un nivel de confianza de 95 % para la comparación de medias. Después de 17 años de la plantación, la supervivencia fue de 89 %. El mayor crecimiento promedio se registró en P. greggii var. australis, con una altura de 10.99 m en la procedencia El Madroño, Qro.; y en la de El Piñón, Hgo., con mayor crecimiento promedio de diámetro basal (20.33 cm), diámetro normal de 15.88 cm, diámetro de copa con 4.52 m y área de copa con 17.81 m2 árbol-1. Los resultados indican la existencia de un efecto de interacción del crecimiento de procedencias en cada localidad. Las procedencias de la variedad australis son las más apropiadas para las reforestaciones de suelos erosionados de Oaxaca.
ECONOMIC DEVELOPMENT OF COUNTRIES DURING THE PANDEMIC CRISIS
Authors:   Plekhanov Russian University of Economics, Gusarova Svetlana
Published: March 2021
