Authors: Barras Hélène , Martius Olivia , Nisi Luca , Schroeer Katharina , Hering Alessandro , Germann Urs
Published: December 2021

Abstract. In Switzerland, hail regularly occurs in multi-day hail clusters. The atmospheric conditions prior to and during multi-day hail clusters are described and contrasted to the conditions prior to and during isolated hail days. The analysis focuses on hail days that occurred between April and September 2002–2019 within 140 km of the Swiss radar network. Hail days north and south of the Alps are defined using a minimum area threshold of a radar-based hail product. Multi-day clusters are defined as 5 d windows containing 4 or 5 hail days and isolated hail days as 5 d windows containing a single hail day. The reanalysis ERA-5 is used to study the large-scale flow in combination with objectively identified cold fronts, atmospheric blocking events, and a weather type classification. Both north and south of the Alps, isolated hail days have frequency maxima in May and August–September, whereas clustered hail days occur mostly in July and August. Composites of atmospheric variables indicate a more stationary and meridionally amplified atmospheric flow both north and south of the Alps during multi-day hail clusters. On clustered hail days north of the Alps, blocks are more frequent over the North Sea, and surface fronts are located farther from Switzerland than on isolated hail days. Clustered hail days north of the Alps are also characterized by significantly higher most unstable convective available potential energy (MUCAPE) values, warmer daily maximum surface temperatures, and higher atmospheric moisture content than isolated hail days. Hence, both stationary flow conditions and anomalous amounts of moisture are necessary for multi-day hail clusters on the north side. In contrast, differences in MUCAPE on the south side between clustered hail days and isolated hail days are small. The mean sea level pressure south of the Alps is significantly deeper, the maximum temperature is colder, and local moisture is significantly lower on isolated hail days. Both north and south of the Alps, the upper-level atmospheric flow over the eastern Atlantic is meridionally more amplified 3 d prior to clustered hail days than prior to isolated days. Moreover, blocking occurs prior to more than 10 % of clustered hail days over Scandinavia, but no blocks occur prior to isolated hail days. Half of the clustered hail days south of the Alps are also clustered north of the Alps. On hail days clustering only south of the Alps, fronts are more frequently located on the Alpine ridge, and local low-level winds are stronger. The temporal clustering of hail days is coupled to specific synoptic- and local-scale flow conditions; this information may be exploited for short- to medium-range forecasts of hail in Switzerland.

Published: December 2021

Abstract. Amplified Arctic ice loss in recent decades has been linked to increased occurrence of extreme mid-latitude weather. The underlying dynamical mechanisms remain elusive, however. Here, we demonstrate a novel mechanism linking freshwater releases into the North Atlantic with summer weather in Europe. Combining remote sensing, atmospheric reanalyses and model simulations, we show that freshwater events in summer trigger progressively sharper sea surface temperature gradients in subsequent winters, destabilising the overlying atmosphere and inducing a northward shift in the North Atlantic Current. In turn, the jet stream over the North Atlantic is deflected northward in the following summers, leading to warmer and drier weather over Europe. Our results suggest that growing Arctic freshwater fluxes will increase the risk of heat waves and droughts over the coming decades, and could yield enhanced predictability of European summer weather, months to years in advance.

Objective: To evaluate effect of Withania coagulans and liraglutide on serum Glucagon like peptide-1, Postprandial and Fasting Blood Glucose levels in streptozotocin induced diabetic rat. Study Design and Setting: This randomize control trile was conducted at Islamic International Medical College in collaboration with National Institute of Health Islamabad. Methodology: This randomized controlled study was performed on a total of forty male Sprague dawly rats, which were initially divided into two groups; Group A (n=10) and Experimental Group (n=30). Diabetes in the Experimental group B was induced by intraperitoneal administration of streptozotocin for 5 days (30mg/kg/day). Diabetes was checked in experimental group by measuring fasting blood glucose (mg/dl) on day 6. Experimental group was further divided into Group B (Diabetic control), Group C (Withania coagulans-treated) and Group D (Liraglutide-treated). Blood sampling was done at day 30 and serum GLP-1, postprandial and fasting blood glucose levels were measured and compared in all groups. Results: Fasting and postprandial blood glucose levels of group C and D were significantly reduced as compared to group B. Serum GLP-1 levels were significantly increased in group C and D as compared to group B. Conclusion: Withania coagulans reduces hyperglycemia in diabetic rats through increasing GLP-1 hormone.

De la teoría del crecimiento económico exógeno al endógeno: un recorrido analítico y conceptual
Authors: Labarca Ferrer Nelson , Márquez Ortiz Luis , Useche Castro Lelly
Published: December 2021

Toda sociedad requiere expandir y diversificar su capacidad productiva. El desafío de las naciones y sus gobiernos es lograr incrementos significativos de los ingresos (renta per cápita) y de las formas de vida de los individuos. El objetivo de este trabajo es dar cuenta de los aspectos teóricos que han determinado el tránsito desde los modelos exógenos a los endógenos. Para eso se desarrolló una investigación bibliográfica, empleando un corpus basado en los principales economistas que han abordado el tema. Se encuentran como algunos resultados que desde mediados de 1940 se han desarrollado toda una serie de modelos conocidos como de crecimiento exógeno, con el capital y el trabajo como variables principales (Solow, 1956). Sin embargo, se determinó que existe otro factor que ese modelo no recogía explícitamente, los desarrollos posteriores al modelo de Solow (1956) fueron y son un esfuerzo para endogeneizar ese tercer factor. Se concluye, que los modelos posteriores a Solow (1956), en especial los de Lucas (1988), Rebelo (1991) y Romer (1986), representaron avances significativos en cubrir las falencias de los modelos exógenos, pero basados en tasas de ahorro estables.

Authors: Suaza Arcila Jorge Oliverio
Published: December 2021

Las habilidades gerenciales se obtienen a partir del conocimiento adquirido desde la educación formal en las universidades. Estas Instituciones trabajan por el desarrollo del ser, hacer y conocer, siendo estas competencias clave en los procesos de formación de individuos que se gestan en estos espacios académicos. Particularmente, en la ciudad de Medellín-Colombia, específicamente en un sector denominado “El hueco”, existen personas que sin haber concluido la educación primaria, y muchos menos disponer de estudios técnicos y universitarios en el área gerencial, se convierten en empresarios catalogados de exitosos. Reúnen experiencias que le soportan el quehacer diario en empresas de la localidad. En función de ello, se torna interesante analizar las habilidades gerenciales de los emprendedores de esta región, particularmente los que lideran pequeñas y medianas empresas. Desde el plano metodológico, se realizó un trabajo de campo, cuantitativo, se encuestaron 120 empresarios de un total aproximado de 400. Se aplicó un cuestionario de preguntas cerradas técnicamente elaboradas y tabuladas para sintetizar la información. Los resultados indican que cada empresario maneja competencias y habilidades esenciales a nivel estratégico y de áreas funcionales clave de las empresas, estas las consolidan desde su quehacer cotidiano. Desde su experiencia gestionan las ventas, proyectando y manejando sus ingresos, y velando de que sus actividades sean rentables, es decir que se administren de manera eficiente. No aplican procedimientos, ni técnicas especializadas en la realización de sus operaciones administrativas (cálculos de precios de ventas y de costos), manejando concepciones tradicionales levantadas desde la experiencia en el quehacer empresarial. Se concluye que: 1) los empresarios pymes definen su propia estrategia de competitividad y se focalizan en la fijación de precios, 2) poseen conocimientos empíricos en la administración de las finanzas y los aspectos contables relativos a costos, 3) gestionan inventarios y costos asociados y, 4) aplican lógica matemática en el establecimiento de sus precios de venta.

Profissionais de apoio à inclusão escolar: motivos para demandas e atribuições
Authors: Mendes Enicéia Gonçalves , Lopes Mariana Moraes
Published: December 2021

A literatura recomenda diferentes profissionais para compor as redes de apoio à inclusão escolar e, no Brasil, nota-se a crescente demanda, por parte de familiares e educadores, do denominado Profissional de Apoio à Inclusão Escolar (PAIE). O presente estudo teve como finalidade descrever e analisar motivos alegados nas demandas por PAIE nas escolas para apoiar estudantes do Público-Alvo da Educação Especial (PAEE). O método multicasos envolveu 30 PAIE de cinco municípios de dois estados brasileiros (três do Estado da Bahia e dois do Estado de São Paulo). Os resultados evidenciaram cinco categorias de justificativas, a saber: 1) promover participação e aprendizagem dos estudantes PAEE; 2) prover suporte em casos de estudantes PAEE com comportamentos desafiadores; 3) prover suporte pedagógico às necessidades de estudantes com impedimentos motores; 4) prover suporte nos cuidados pessoais básicos (higiene pessoal, locomoção e alimentação) e; 5) prover suporte para evitar que o estudante PAEE atrapalhe sua turma, retirando-o da sala de aula. Conclui-se que algumas dessas justificativas são justificadas, enquanto que outras encobrem mecanismos de exclusão e políticas de barateamento dos suportes profissionais, e que a judicialização das demandas pode estar contribuindo para assim as manter.

Published: December 2021

O objetivo deste artigo é compreender como as questões étnico-raciais estão sendo trabalhadas no cotidiano escolar da Educação Básica, tendo como parâmetro dados obtidos em dissertações e teses da área da Educação. A metodologia utilizada possui como base a abordagem crítico dialética, com foco nas categorias conteúdo e forma, e como pressupostos os estudos de Cury (1985) e Gamboa (2012). As questões étnico-raciais são tratadas à luz dos postulados de Hall (1990), Quijano (2005), Silva (2000) e Nájera (2018). Os resultados revelam que as práticas pedagógicas desenvolvidas no cotidiano escolar e no âmbito dos cursos de formação continuada de professores necessitam ter como base teórico-metodológica a perspectiva intercultural, a qual possibilita buscar a constituição de uma postura de igualdade de tratamento que a modernidade prometeu por meio do contrato social e que, infelizmente, na sociedade contemporânea, ainda não se cumpriu efetivamente.

An Empirical Study on the Influence of Asset-backed Securitization on the Profitability and Liquidity of Commercial Banks of China
Authors: Yang Di-Chuan
Published: December 2021

This paper uses the panel data of Chinese commercial banks to analyze the impact of credit asset-backed securitization on the profitability and liquidity of Chinese commercial banks. The results show that there is a significant negative correlation between asset-backed securitization and the profitability of commercial banks in China. The main reason for this phenomenon is that China’s credit asset-backed securitization is still in the pilot stage. The main purpose of asset-backed securitization is not to improve the level of profitability, but to broaden the financing channels, in addition, the high transaction cost of asset-backed securitization is also an important reason. However, there is no significant correlation between asset-backed securitization and the liquidity of commercial banks in China. The reason is that although asset-backed securitization can make the future income of banks cash in advance, considering the efficiency of capital use and the rationality of assets and liabilities, banks will use these funds to make new loans, which reduces the liquidity of banks.

The Analysis of Automatic Adjustment Mechanism of Balance of Payments-Evidence from Manufactured Goods Exporters
Authors: Yang Jia-Hua , Yang Grant G. L.
Published: December 2021

The balance of payments is the most scientific and complete record of international economic exchanges and transaction flows, and will be affected by interest rates, exchange rates, trade, finance, foreign exchange management and foreign investment. Studies related to balance of payment dominate in those increasingly open and developing economies, particularly for the manufactured goods exporters where manufacturing is the backbone, driver and display of modernization. This paper explores time trend analysis to analyze the automatic adjustment mechanism of balance of payments for manufactured goods exporters based on data from United Nations Conference on Trade and Development. The stability, cointegration, and causality tests are performed followed by multiple regression analysis that corporates one-period lagged and log-formed models. The results are found to be consistent with theoretical analysis except for foreign direct investment. Granger causality tests demonstrate consumer price index and export are the causes of foreign direct investment, which might distort the explanation of foreign direct investment to balance of payment for manufactured goods exporters.

Complicated urinary tract infection in a patient with severe COVID-19
Authors: Andreev S. S. , Isaev T. K. , Trushkin R. N. , Kantimerov D. F.
Published: December 2021

Introduction. At the end of 2019, the world faced a pandemic of infection caused by the SARS-CoV-2 coronavirus. The disease caused by this virus is referred to as COVID-19, and is characterized by multiorgan lesion. The leading syndrome is the syndrome of immune response disregulation or the «cytokine storm». According to the studies, which were used as the basis of patient management clinical protocols, antiinterleukin-6 agents, and glucocorticosteroids, are the most effective in stopping the «cytokine storm». At the same time, the use of immunosuppressive drugs increases the risk of secondary infectious complications not associated with the COVID-19 viral infection.

The aim of the study was to present a successful case of treating a secondary bacterial infection in a patient with a severe new coronavirus infection in the context of a limited choice of antimicrobial therapy.

Materials and methods. The report presents a clinical case of a complicated urinary tract infection associated with an extremely resistant Kl.pneumoniae strain in a 58-year-old patient hospitalized with severe COVID-19. Due to comorbidity, combined with long-term hospitalization, the need in immunosuppressive therapy, and long-term catheterization of the urinary tract, the patient got affected by Kl.pneumoniae. This pathogen demonstrated microbiological and clinical resistance to all studied classes of antibiotics, including carbapenems, aminoglycosides and polymyxins. The patient developed an abscess of the prostate, and orchiepididymitis, which required repeated surgical interventions.

Results and Discussion. The multidisciplinary approach to patient treatment, as well as the use of local and regional epidemiological data made it possible to choose the most effective drug therapy. The combination of adequate surgical debridement and combined antibiotic therapy (ceftazidime/avibactam and aztreonam) led to regression of the complicated urinary tract infection manifestations and clinical recovery.

Conclusions. The use of ceftazidime/avibactam and aztreonam combination is a promising therapeutic option for the treatment of infections caused by extremely resistant strains of Enterobacterales, in which the combined production of serine proteases and metallobetalactamases is expected.
Industrial Relations and Labour Management and Productivity: The Imperative for Sustainable Development in Nigeria
Authors: O.O. Ojo , A.M. Adedayo
Published: December 2021

Industrial relations, labour management and productivity have their roots in the industrial revolution which created the modern labour relationship by spawning large-scale industrial organizations. As society wrestled with these massive economic and social changes, labour problems aroused coupled with societal reconstruction challenges. Premised on this background, this paper is set to discuss the conceptual meaning of labour and industrial relations, assess the roles and prospects of labour in Nigeria, examine the consequential effects of labour-industrial relations and examine challenges of labour productivity and management in Nigeria. The paper also discusses some frameworks for labour-industrial relations. It focuses attention on the changing structure of the labour environment and the rise of precarious working conditions orchestrated by various unrests and acrimonies from nonchalant attitudes and behaviours of government and private sectors towards labour/workers’ welfare and patronage. The data for this study were collected through secondary sources. The secondary data were obtained from textbooks, journals, newspapers, internet materials and literature from academic journals in relation to the subject studied. The study adopted Industrial Relations Theory as a theoretical framework. The paper concludes that labour and industrial relations are part of the critical factors and are tools in advancing industrial productivity and attaining sustainable development in Nigeria.
Nicolae Macarenco - representative artist of satirical graphics
Authors:   Institute of Cultural Heritage, Republic of Moldova, Adascalița-Crigan Lucia
Published: December 2021

A prominent figure in the field of satirical graphics in the Republic of Moldova, Nicolae Macarenco, throughout his artistic career, conceived with great skill and dedication book illustrations for literary works signed by Aureliu Busuioc, Evgeniy Kopylov, Iosif Gherasimov, Alla Grekul, posters and aesthetically expressive and semantically valuable caricatures. Prodigious, talented, persevering and devoted to his profession, the protagonist is one of the established artists who, through his vocation and talent, marked an entire era in the satirical art of the Republic. Working successfully, especially in the genres of satirical-humorous graphics, the graphic designer gave birth to works that were frequently published in important periodicals such as the satire and humor magazine Chipăruş, the magazine Femeia Moldovei, the newspaper Tinerimea Moldovei and others. The study highlights both the thematic aspects of the artist’s creation and the determined, systematized, mirrored artistic options of the protagonist. Having examined the artist’s works, the author pays increased attention to problems of compositional image, the particularities of plastic representation through shape, line, tone of human characters, psychological states of anthropomorphic and zoomorphic characters. At the same time, the analytical approach is supported by highlighting the role of color in the process of amplifying expressions and messages generated by satirical works created by the graphic artist.
Divan film festival or the story of a big small festival of cinematographic and culinary art in the Balkans
Authors:   George Oprescu Institute of Art History, Romania, Tutui Marian
Published: December 2021

In 2010 a small festival on Balkan cuisine and cinema, leaving aside the competition and prizes, endeavored to promote a unifying perspective on the cinema of 10 nations: Balkan film studies. It is the merit of the great writer and recently chef Mircea Dinescu, of the amazing settlement on the banks of the Danube, where the borders of Romania, Bulgaria and Serbia meet, of some serious scholars, as well as of the great value of the Balkan films of the last decades that imposed the expression “Balkan film”. Paradoxically, while ethnic conflicts have provoked terrible experiences for the inhabitants of the Balkans and erected new borders, the filmmakers seem to have benefited from the authentic drama and have learned to better address the surrounding nations as well.

In recent years, we can find several attempts to reconstruct the performances of famous choreographers who worked in the 1920s and 1930s. Modern choreographers have recalled forgotten performances of the former era, but recalling these choreographic works, they want to give them a modern meaning. This attempt is similar to rewriting history. In this context of rewriting history, I want to emphasize the importance of bodily memory and bring the perspective of viewing the body as an archive. In my article, I pose questions about how to find traces of former works? How modern choreographers work with memory and with the body. The concept of the body as an archive and the experience of past generations associated with choreographic practice is at the center of my work. The body can hide the secret of trauma, the unconscious determination of behavior in bodily, physical play. The second problem raised in the article is about the relationship between the present and the past. Why do we need a turn in the past now? I consider Yanka Rudskaya’s biography and her approach to dance as an example. This article shows the role of feminine artistic practices in the space of choreography. Recent reflections concern the problem of transferring modern dance to modernity and its discovery.
The prenatal period and related prohibitions and prescriptions among the Old Believers of the Republic of Moldova
Authors:   Institute of Cultural Heritage, Republic of Moldova, Zaicovscaia Tatiana
Published: December 2021

The author presents some results of her research of the indicated period, which was carried out on the basis of a specially compiled questionnaire in places of compact residence of Lipovans in such villages as Kunicha, Egorovka, etc., as well as in the city of Chisinau. There are a number of preventive actions and prohibitions aimed at ensuring the health and strength of the woman in labor and her baby. Often they are based on common sense, on pragmatics, but not always the informants could explain the reasons for certain prohibitions. A pregnant woman was prohibited from doing, for example, the following actions: sewing; stepping over a long (wire, rope) or sharp object; contacting with animal hair (dogs, cats, etc.); touching her own body when frightened (for example, during a fire); looking at the deceased through the window, etc. According to the testimony of informants, much attention was paid to protecting the woman in labor from the „evil eye”. And if this happened, then they were treated with prayers and herbs. There were also signs by which they tried to guess the sex of the unborn child. Before giving birth, a woman usually confesses to her spiritual father.
Dwelling in novellistic fairy tales and anecdotes of the Bulgarians of Moldova (ethnocultural features)
Authors:   Institute of Cultural Heritage, Republic of Moldova, Cara Nadejda
Published: December 2021

The author analyzed the functional, symbolic, and semantic features of the traditional dwelling of the Bulgarians of the Republic of Moldova in fairy-tale folklore (novelistic tales and anecdotes). The types of dwellings and their constituent elements (internal and external) were considered as a part of the material; culture is reflected through subject realities as a component of ethnic culture in the human microcosm. The connection of dwelling with traditional values of the Bulgarians of the Republic of Moldova was also analyzed.
Interpretative ethnological model “decalogue and harmonizing hermeneutic maxims of obligatoriness: an aspect of upbringing”: on the example of the memoir prose of a native of Chisinau
Authors:   Institute of Cultural Heritage, Republic of Moldova, Cusnir Josefina
Published: December 2021

The interpretive ethnological model “The Decalogue and Harmonizing Hermeneutic Maxims of Obligatoriness: An Aspect of Upbringing” is developed within the framework of a noetic interdisciplinary system of our four concepts (concept of humanization of myth; concept of megamodern; concept of ethicizing mythological consciousness; concept of aesthetic meaning). This system is based on the works by many outstanding scholars, including the achievements of interpretive (hermeneutic) anthropology by C. Geertz, the ideas of J.J. Wunenburger, K. Hubner, V. Frankl, E. Fromm, N. Berdyaev, J. Ortega y Gasset, K. Jaspers, etc. In the interpretative model, the eight “implicit principles of upbringing (world perception, behavior) according to the Decalogue” revealed by us are applied: these principles are based on the concept of man and the Universe represented in the Ten Commandments. This model allows examining distinct hermeneutic maxims as a sort of ethnocultural specificity of shaping the epoch of “new humanism for the 21st century” (UNESCO). A Family Portrait in the Midst of Chisinau Landscape, memoir prose by Susanna Cușnir, is examined according to this model. One of the revealed hermeneutic maxims reads: “The Universe is such that man can follow his creative impulses at any age”.
Smart Inhaler

As per the World Health Organization released during May 2018, 9 out of 10 individuals are believed to breathe air containing high levels of pollutants. Studies reveal, above 90% of air pollution-related deaths worldwide occur in low- and middle-income countries, especially in Asian and African countries, followed by low- and middle-income countries of the Eastern Mediterranean, European and the American regions. As per the University of Washington’s Global Burden of Disease study, 2018, COPD was the second-highest cause of death in India, leading to the death of almost 958,000. Inhalers are essential for observing the strict regimen required for these conditions, as they avoid the need for and the adverse effects associated with the use of injectables and oral drugs.Inhalers are used to treat chronic obstructive pulmonary disease (COPD), such as asthma, by delivering bronchodilator medication to the airway directly, without passing through the blood. ‘Smart’ inhalers are inhalers with extra digital features – they link to an app on the phone or tablet to help the patient and the doctor to manage asthma better.

Hardware and Software Complex for Detection and Visualization of Subsurface Blood Vessels During Brain Tumors Resection
Authors: Udeneev A. M.
Published: December 2021

Purpose: The purpose of this work is to prove the possibility of subsurface blood vessels detection during endoscopic resection of brain tumors using the method of endoscopy in red and near infrared light.

Material and methods: This work was accomplished with an experimental setup, simulating the geometry of endoscopic resection of brain tumor. The setup realizes the backlight of operational field with light from diagnostic window of electromagnetic spectrum (650 1000 nm) and takes photos of operational field. After that special algorithm increases the contrast of the photos and detect subsurface blood vessels.

The pieces of bovine brain have served as brain samples. And thin-walled transparent plastic tube with an internal diameter 1 mm filled with bovine blood has served as a blood vessel. The tube was placed into brain samples on different depths.

Results: During the experiments the series of photos of bovine brain with artificial blood vessels located on different depths was received. For every photo contrast was increased and blood vessel was recognized.

Conclusion: The series of experiments has showed the possibility to detect the blood vessels with outer diameter 1 mm in the depth of 2 mm and 3 mm in brain tissues using the method of endoscopy in red and near infrared light. The depth of 3 mm is enough for preliminary detection of blood vessel during the endoscopic resection of brain tumor.
Bringing metamaterials to creative industries and hospitals
Authors: Memoli Gianluca
Published: December 2021

According to different recent market research reports, acoustic metamaterials are quickly going up the TRL scale, moving to applications. In this talk, I will therefore present two examples of applications: one relative to sound delivery and one to noise management, both for audible frequencies in air.

First, I will describe how combinations of metasurfaces can be used to achieve sound delivery with wavelength precision at variable distances, for creative applications. I will touch on the possibility of applying the thin-lens equation and on the verification of COMSOL simulations using human volunteers.

Secondly, I will discuss how my team came to design meta-material based movable panels to COVID wards. I will touch on the criticality of noise in hospitals, on the specific combination of unit cells that we used and on the challenges to test the performance of our panels using standard techniques, both in the laboratory and in-situ.
