Tax Incentivisation of Debt Financing vs. Equity Financing: Present Status and Approaches to Solve the Tax Asymmetry
Authors: Halíček Radek , Karfíková Marie
Published: December 2022

Historically, the cost of financing business through debt has reduced income tax paid. Financing via new equity has not. This asymmetry has not been without consequences. The high indebtedness and relative undercapitalisation of corporates creates a risk of reduced resilience to economic shocks. Some countries have introduced tax incentivisation of equity, reduced tax incentivisation of debt, or both. In June 2022, the European Commission proposed a harmonised solution: Debt Equity Bias Reduction Allowance (DEBRA). All EU Member States, including the Czech Republic, should provide corporate income tax deduction for equity, whilst further limiting interest deduction, starting 2024.
Virtuálne meny (právna podstata, regulačný rámec a zdaňovanie)
Authors: Štrkolec Miroslav
Published: December 2022

Virtual currencies have been part of economic reality for more than a decade but have only become the subject of legal regulation at European and national level in recent years. This is in a sense natural, since law as a normative system reacts only with a certain time lag to already existing facts, circumstances, and relations which, due to their impact, require legal regulation. The author deals with the legal nature of virtual currencies and their relationship to categories such as money, currency, crypto assets. The article then defines their regulatory framework and taxation in terms of de lege lata and de lege ferenda. The paper concludes with thoughts towards the future of virtual currencies in financial and tax law.
Pojištění zaměstnavatele za škodu při pracovním úrazu nebo nemoci z povolání z pohledu finančněprávní teorie
Authors: Vybíral Roman
Published: December 2022

The paper deals with the system of employer’s insurance for damages in the event of a work accident or occupational disease from the perspective of financial law (especially tax law). First of all, the author discusses the theoretical nature of this insurance and its establishment in the Czech legal system. In the following parts of the paper, the author deals with further legal implications of the results of his findings, namely whether the paid insurance premium has the character of a tax or an insurance premium from a theoretical point of view. He then places these results in the context of the assessment of constitutionality within the meaning of Article 11(5) and Article 4(1) of the Charter of Fundamental Rights and Freedoms.
„Wir haben keinen Plan B“
Authors: Simon Hendrik , Brinkmann Ulrich , Paulitz Tanja
Published: December 2022

Der Beitrag argumentiert, dass hinter der Implementierung digitaler Technologien in Großunternehmen oftmals alte Interessenkonflikte stehen, die im Zuge der Digitalisierung verschärft und auf neue Felder verlagert werden. In der dichten Beschreibung eines durch teilnehmende Beobachtung begleiteten Implementierungsprozesses wird die Chronik einer gescheiterten Digitalisierung rekonstruiert. Dabei verweisen wir auf konkurrierende Interessen im Kampf um das Regulierungsniveau der Digitalisierung ebenso wie auf innerbetriebliche Strategien, die angewendet werden, um das sich abzeichnende Scheitern des Implementierungsprozesses zu verschleiern: Weil die neue digitale Technik von den Beschäftigten boykottiert wird, errichtet die verantwortliche Steuerungsgruppe „Top-down“-Fassaden, um die Digitalisierung unternehmensintern dennoch als Erfolg zu verkaufen. Paradoxerweise provoziert aber gerade diese Legitimationsstrategie einen Fassadenbau auch aufseiten der Beschäftigten „bottom-up“. Die organisationsethnografische Fallstudie macht damit eine Vielfalt lokaler Rationalitäten im innerbetrieblichen Digitalisierungskonflikt jenseits des eindeutigen Digitalisierungsdiskurses auf den Vorderbühnen des Unternehmens sichtbar.
Weighted composition operators on Hardy–Smirnov spaces
Authors: Matache Valentin
Published: December 2022

Operators of type f → ψf ◦ φ acting on function spaces are called weighted composition operators. If the weight function ψ is the constant function 1, then they are called composition operators. We consider weighted composition operators acting on Hardy–Smirnov spaces and prove that their unitarily invariant properties are reducible to the study of weighted composition operators on the classical Hardy space over a disc. We give examples of such results, for instance proving that Forelli’s theorem saying that the isometries of non–Hilbert Hardy spaces over the unit disc need to be special weighted composition operators extends to all non–Hilbert Hardy–Smirnov spaces. A thorough study of boundedness of weighted composition operators is performed.

Published: December 2022

Objectives

To evaluate the association of clinician demographics and practice patterns with delayed diagnosis of appendicitis.

Methods

We included children with appendicitis at 13 regional emergency departments (EDs). We screened patients with a previous ED visit within 7 days for delayed diagnosis by chart review. We evaluated the association of clinician characteristics using logistic regression with random intercepts for site and clinician and delay as the outcome.

Results

Among 7,452 children with appendicitis, 105 (1.4%) had delayed diagnosis. Clinicians in the lowest quartile of obtaining blood in their general practice were more likely to have delayed diagnosis (odds ratio 4.9 compared to highest quartile, 95% confidence interval 1.8, 13.8). Clinicians’ imaging rates, specialty, sex, and experience were not associated with delayed diagnosis.

Conclusions

Clinicians who used more blood tests in their general practice had a lower risk of delayed diagnosis of appendicitis, possible evidence that lower risk tolerance has benefits.
Inhibition of miR-21 improves pulmonary vascular responses in bronchopulmonary dysplasia by targeting the DDAH1/ADMA/NO pathway
Authors: Zhong Ying , Zhang Zhiqun , Chen Xiaoqing
Published: December 2022

miR-21 has been confirmed to be overexpressed in neonatal rat lungs with hyperoxia-mediated bronchopulmonary dysplasia (BPD). The specific function of miR-21 in BPD is still unclear. We established the hyperoxia-induced BPD rat model in vivo and the hyperoxia-induced pulmonary microvascular endothelial cells (PMVECs) model in vitro. Transwell assay was utilized to detect the migratory capability of PMVECs. Tube formation assay was utilized to measure angiogenesis ability. ELISA was utilized to test nitric oxide (NO) production and the intracellular and extracellular Asymmetric Dimethylarginine (ADMA) concentration. Furthermore, the interaction between miR-21 and dimethylarginine dimethylaminohydrolase 1 (DDAH1) was evaluated using luciferase reporter assay. We found that miR-21 expression in PMVECs was increased by hyperoxia stimulation. Inhibition of miR-21 improved the migratory and angiogenic activities of PMVECs and overexpression of miR-21 exerted the opposite effects. Furthermore, knockdown of miR-21 increased NO production and decreased intracellular and extracellular ADMA concentration in hyperoxia-treated PMVECs. Next we proved that miR-21 could bind to DDAH1 and negatively regulate its expression. Rescues assays showed that DDAH1 knockdown reversed the effects of miR-21 depletion on hyperoxia-mediated PMVEC functions, NO production, and ADMA concentration. Importantly, miR-21 downregulation restored alveolarization and vascular density in BPD rats. This study demonstrates that inhibition of miR-21 improves pulmonary vascular responses in BPD by targeting the DDAH1/ADMA/NO pathway.

Introduction to the Special Issue on Authoritarian Resilience of Communist Regimes in Asia
Authors: Vu Tuong
Published: December 2022

This special issue focuses on the resilience of the communist regimes in Laos, Cambodia, Vietnam, and China. Three decades after the collapse of the Soviet Bloc, all four not only survived a hostile post-communist world dominated by liberal capitalism but have thrived economically. The five articles in this special issue hope to build on existing scholarship on authoritarian resilience while contributing in the following ways. First, by adopting a regional framework, we hope to offer a fuller examination of varieties in communist Asia. After all, this is the only world region with such a large concentration of surviving communist parties. Second, while highlighting the critical role of revolutionary origins, our approach corrects the tendency in scholarship on democratic transition that neglects the totalitarian legacies. Third, the articles support the institutionalist approach by showing how ruling parties in authoritarian regimes are critical; yet we also seek to balance between historical legacies and contemporary developments and to analyze the interactions among ideologies, organizations, and resources.
COVID-19 Y TELEDOCENCIA UNIVERSITARIA EN ESPAÑA. EL CASO PRÁCTICO DE LAS TITULACIONES DE PERIODISMO Y COMUNICACIÓN
Authors: Gómez  López Concepción
Published: December 2022

La crisis del coronavirus modificó las rutinas laborales de todos los ámbitos profesionales,

La crisis del coronavirus modificó las rutinas laborales de todos los ámbitos profesionales, incluso el de la enseñanza universitaria con la clausura temporal de los edificios académicos. Las universidades españolas siguieron funcionando pese a la restricción de movimientos (Decreto de Estado de Alarma del 14 de marzo de 2020) ya que el profesorado modificó sus rutinas ajustando los procedimientos de su actividad docente teórico-práctica a los requerimientos de la docencia no presencial.

Este artículo es una aproximación a las percepciones y a la experiencia del profesorado universitario durante la pandemia y la etapa pospandémica. Metodológicamente se compara el estudio de caso realizado previamente en la Facultad de Ciencias Sociales y Comunicación de Pontevedra (Gómez López y Alende Castro, 2022) con los hallazgos de la presente publicación facilitados por docentes de las universidades de Navarra, Pontificia de Salamanca, Complutense de Madrid, Salamanca, Pompeu Fabra, La Laguna, Santiago de Compostela y A Coruña. El estudio conlleva una metodología mixta, con datos recogidos a partir de un cuestionario tipo y de una entrevista.

Los resultados determinan que el esfuerzo realizado por los docentes españoles y los centros de educación superior suplieron las limitaciones del aula física durante la pandemia, pero trasladando al aula virtual los recursos propios de la metodología presencial, no apreciándose, sin embargo, progresos significativos en nuevas metodologías docentes que permitan avanzar hacia modelos educativos más flexibles.
The possible influence of socio-cultural and socio-economic parameters on local languages: the case of Šalčininkai District
Authors: Čepaitienė Agnė
Published: December 2022

The aim of the study is to use GIS tools and methods to identify the mobility trends of the members of the local communities of Šalčininkai district and surrounding areas and their impact on the local languages on the basis of socio-economic and socio-cultural parameters. The research material consists of: 1) survey data, on the basis of which the coefficients of the influence of attractions on the language were calculated; 2) statistical socio-economic data for 2020-2021; 3) geo-spatial data of Lithuania; 4) linguistic studies of Šalčininkai district. GIS tools and methods were used to assess the infrastructure of residential areas, a heat map of attractions with the greatest impact on linguistic shift was created based on the results of the survey, and a link network of Atlas of Lithuanian Language (ALL) points and infrastructures was implemented through accessibility analysis. Based on social network theory, the structure of socio-cultural networks and their influence on linguistic shift, as well as the influence of additional socio-economic and socio-cultural factors was assessed. The analysis has highlighted the linguistic, socio-economic and socio-cultural uniqueness of Šalčininkai district. The study area is a zone with a more internal mobility level: there is less migration between areas where different languages (Slavic and Lithuanian) are spoken, and more migration between different dialects (Eastern Aukštaitians of Vilnius and Southern Aukštaitians). However, due to the disappearance of ALL points in almost half of Šalčininkai district, the well-developed infrastructure in the district centre and the abundance of elderly communities in the district, the intensity of mobility is low. Therefore, all the areas surveyed can be considered socio-culturally non-isolated, but linguistically quite isolated. This ensures the survival and dominance of the Slavic language. The centre of the district – Šalčininkai (ALL 666) - is considered to be the most socio-economically and socio-culturally stable in the study area. However, this town attracts residents from socially unstable areas and residents of different dialects. This creates favourable socio-economic and socio-cultural conditions for the Slavic languages (partly also for Lithuanian dialects) to compete, but remain viable. The other ALL points in Šalčininkai district belong to the open zone, where the processes of shift in the characteristics of Slavic languages and/or Lithuanian dialects are taking place.

Published: December 2022

Вступ. Попри невизначеність термінів та умов повоєнного відновлення України, ресурсоємність та комплексність цього завдання, його успішне виконання створюватиме унікальні можливості для проведення необхідних інституційних реформ та радикальної структурної трансформації економіки. Пріоритети та ефективні механізми реалізації такої політики відновлення повинні бути сформульовані з урахуванням регіональних та глобальних напрямів соціоекономічних і гуманітарних перетворень, одним з основних серед яких є перехід до низьковуглецевої (вуглецевонейтральної) моделі розвитку.Проблематика. Ухвалення цілі зі скорочення викидів парникових газів відповідно до оновленого Національно визначеного внеску до Паризької угоди задало кількісний вимір низьковуглецевого розвитку України. Актуальним завданням постає як формулювання базових імперативів державної політики, так і визначення завдань і заходів,спрямованих на досягнення заявленої мети та ефективного долучення України до Зеленого курсу ЄС в умовах повоєнного відновлення.Мета. Оцінювання цільових змін структурних пропорцій енергетичного та електробалансів, а також відповіднихмакроекономічних ефектів.Матеріали й методи. Оцінювання наслідків досягнення кліматичної цілі виконано з використанням прикладноїлінійної квазідинамічної оптимізаційної моделі енергетичної системи TIMES-Україна.Результати. Магістральними напрямами декарбонізації економіки запропоновано розглядати енергоефективність, розвиток відновлюваних джерел енергії, технологічну модернізацію з відповідним переспрямуванням інвестицій в розвиток низьковуглецевих технологій, а також формування конкурентних інтегрованих енергетичних ринків.Висновки. Хоча енергетичний сектор відіграватиме ключову роль у післявоєнному «зеленому» відновленні економіки України, увага держави не може обмежуватися галузевими рамками, оскільки відповідні ефекти також пов’язані з фінансовою, соціальною, фіскальною, конкурентною та інфраструктурної політиками.

Authors: Yegorov I. , Kotlyarevskyy Y. , Marchenko V. , Osetskyi V. , Elrabay'a D.
Published: December 2022

Introduction. The need to pursue more active government policy for the stimulation of waste processing is causedby the necessity to prevent those threats that arise unless an environment friendly and efficient waste management system is in place.Problem Statement. Ukraine demonstrates a low level of household waste recycling, which poses a hazard to theenvironment, quality of life, and health of the population of Ukraine. The measures identified in the National WasteManagement Strategy until 2030 can be implemented by combining the organization of separate collection of household waste with the revision of the existing incentives aiming at increasing the demand for secondary resources.Purpose. The purpose of this research is to generalize the causes of low amount and rates of processing ofhousehold waste and to develop a system of economic tools for the formation of supply and demand for household waste as main factors of effective strategic waste management.Material and Methods. Qualitative analysis and generalization of theoretical material, systematization ofeconomic tools of household waste management, economic and statistical analysis, and regression analysis have been used in this research.
Results. A set of tools for strategic household waste management and changes in approaches to their formation have been proposed. The formation of waste management tariff should be based on the length of the waste management chain, the structure of the collected waste, the potential for its recycling, the revised methods for forming the tariff, organizing waste sorting, andamending the list of tax payers of environmental tax.Conclusions. The household waste management in Ukraine demonstrates certain stability of the waste processing structure and the absence of dynamic transformations in response to changes in the modern economy. It needs support, in particular, the revision of the set of economic tools for stimulating waste processing and organizational approaches to their implementation.

Вступ. Зростання інтересу до освоєння космічного простору та нові технології супутникової навігації та зв’язку призвели до збільшення кількості космічних апаратів (КА) на навколоземних орбітах і створення орбітальних угрупувань. На сьогодні головним засобом, що здійснює виведення КА на навколоземні орбіти, є ракети-носії, відпрацьовані верхні ступені яких, після виведення КА, залишаються на навколоземних орбітах і уворюють космічне сміття (КС).Проблематика. Проблема зростання кількості КС є однією із ключових у сучасній космонавтиці. Значне накопичення фрагментів КС на деяких кластерах орбіт може чинити значні перешкоди діючим КА, а також призвести до глобальних проблем — ефекту Кеслера. Одним із джерел зростання КС є відпрацьовані верхні ступені ракет-носіїв (РН). Розробка засобів відведення верхніх ступенів РН з навколоземних орбіт є актуальною, а проєкт РН легко класу «Циклон-1М» розробки ДП «КБ «Південне» ім. М. К. Янгеля» є однією з перспективних розробок.Мета. Розробка науково-технічного забезпечення модернізації аеродинамічної системи відведення для використання на верхньому ступені ракети-носія «Циклон-1М».Матеріали й методи дослідження. Застосовано методи прикладної механіки, математичного й комп’ютерного моделювання руху космічних апаратів.Результати. Розроблено науково-технічне забезпечення для створення нової аеродинамічної системи відведення (АСВ) верхнього ступеня РН «Циклон-1М». Створено нову конструкцію аеродинамічного елементу АСВ у формі трьох ортогонально розміщених круглих дисків, що дозволяє підвищити ефективність застосування АСВ. Запропоновано конструктивну схему та технологію виготовлення контейнера для зберігання АСВ на верхньому ступені РН «Циклон-1М» з використанням сотових технологій, що дозволяє мінімізувати масу системи.Висновки. Технічний результат запропонованої розробки демонструє збільшення ефективності застосування АСВ при неорієнтованому кутовому русі під час відведення РН та дозволяє зменшити масу системи зберігання.

Вступ. На сьогодні в Україні не існує централізованої масштабованої системи збору й обробки відеоданих, яка б дозволяла контролювати дорожню та придорожню обстановку.Проблематика. Зазвичай для систем контролю використовують стаціонарні камери. Оскільки камер необхідно багато, виникає проблема передачі інформації (створення та обслуговування розгалуженої мережі передачі даних) та її обробки (створення центрів обробки та зберігання отриманих даних).Мета. Створення системи збору відеоданих за дорожньою та придорожньою обстановкою, а також обстановкою в транспорті загального користування для розкриття злочинів, що відбулися в зонах відеонагляду.Матеріали й методи. Використано смартфон та відеокамеру, на яких було протестовано функції й алгоритми розробленої авторами системи. Для зменшення об’ємів інформації застосовано методи селективного сприйняття відеоінформації, визначення рухомих об’єктів, методи паралельної та конвеєрної обробки відеоінформації для прискорення їхньої обробки, методи й засоби швидкого виділення інформативних ознак для пошуку та розпізнавання об’єктів.Результати. Запропоновано концепцію та структуру апаратного й програмного забезпечення системи мобільного відеонагляду, структуру системи захищено патентом України на корисну модель. Розроблено та створено за участі партнера спеціалізовану відеокамеру для зйомки й аналізу відеоданих, а також компоненти системи для реалізації функцій автоматичного детектування на зображенні номерів автомобілів та їх розпізнавання, автоматичного виділення облич людей з визначенням відсутності на них масок для подальшого комп’ютерного аналізу.Висновки. Використання мобільних систем зазначеного типу дозволить розширити зону відеонагляду в містах і поза містом та зменшить затрати на впровадження дорожніх систем відеофіксації.

Protective and Unequal? Caregiver Presence During Pediatric Hospitalizations
Authors: Lin Karen , White Michelle J. , Holliday Katelyn M. , Parnell Lisa S. , Parente Victoria M.
Published: December 2022

OBJECTIVES:

Describe the association between caregiver presence on hospital day 1 and outcomes related to readmissions, pain, and adverse events (AE).

METHODS:

Caregiver presence during general pediatrics rounds on hospital day 1 was recorded, along with demographic data and clinical outcomes via chart review. AE data were obtained from the safety reporting system. χ2 tests compared demographic characteristics between present and absent caregivers. Background elimination determined significant predictors of caregiver presence and their association with outcomes.

RESULTS:

A total of 324 families were assessed (34.9% non-Hispanic white, 41.4% Black, 17% Hispanic or Latinx, 6.8% other race or ethnicity). Adolescents (aged ≥14 years) had increased odds of not having a caregiver present compared with 6- to 13-year-olds (36.2% vs 10%; adjusted odds ratio [aOR] 5.11 [95% confidence interval (CI) 1.88–13.87]). Publicly insured children were more likely to not have a caregiver present versus privately insured children (25.1% vs 12.4%; aOR 2.38 [95% CI 1.19–4.73]). Compared with having a caregiver present, children without caregivers were more likely to be readmitted at 7 days (aOR 3.6 [95% CI 1.0–12.2]), receive opiates for moderate/severe pain control (aOR 11.5 [95% CI 1.7–75.7]), and have an AE reported (aOR 4.0 [95% CI 1.0–15.1]).

CONCLUSIONS:

Adolescents and children with public insurance were less likely to have a caregiver present. Not having a caregiver present was associated with increased readmission, opiate prescription, and AE reporting. Further research is needed to delineate whether associations with clinical outcomes reflect differences in quality of care and decrease barriers to caregiver presence.
Music Analysis as a Description of Eventing in Time: A Phenomenological Description of Bartók's Improvisation op. 20 no. 3
Authors: Mohammad Iyad A.
Published: December 2022

This article offers a phenomenological description of Béla Bartók's Improvisation op. 20 no. 3, with a focus on temporality as experienced in listening. Such a description aims at understanding the structure of eventings, through which we encounter and experience, grasp and take up the work's Gestalt in time as a singular dynamic whole, which is its being as becoming, its presentation in its idea and form. As a result, what we hear, perceive and understand as we listen to the work is revealed as the unfolding of a complex network of intersecting eventings, the crossing of contrarily directed motions, interpenetration of intonations and gestures, circularities on different perceptual levels from delaying and returning notes, intonations, gestures and themes, to thematic repetition and variation, their recallings and cross-referencing. These micro-eventings yield eventings on a larger perceptual level that include ternarity, cyclicity in its broadest sense and a concentric concave-shaped contour. This is the work's Gestalt; the unique balance as ratio, correlation and interrelation, not equilibrium, of all these eventings and temporalities.
Before The Wooden Prince: Károly Szabados's Ballet Vióra (1891) in the Context of the History of Hungarian Ballet
Authors: Ujvári Hedvig
Published: December 2022

Following the debut of Károly Szabados's ballet Vióra on March 14, 1891, the daily newspaper Pesti Hírlap called the date a glorious day not only for Hungarian music, but also for Hungarian genius and spirit in general, and treated the debut at the Hungarian Royal Opera House in Budapest as an allegory for spring: “It was as if the refreshing, revitalizing breaths of that traditional March breeze had blown across the hall of muses on Andrássy Road: such was the enthusiasm dominating the spectators' benches and the stage alike.”1 According to the newspaper, it was the long-anticipated victory of “the Hungarian genius, which some had begun to consider as almost alien to the Hungarian royal theater,” and it was all thanks to Géza Zichy (1849–1924), one of whose first acts as intendant was bringing this long neglected piece to the stage.2 In the context of Vióra's premiere, the “Hungarian genius” and the “Hungarian spirit” manifested on several levels, as it was the decision of a Hungarian intendant to present the evening-long ballet of a Hungarian author revolving around Hungarian themes; but this raises the question, why did a Hungarian ballet carry such significance at the time? What place does Károly Szabados, the author of the ballet, occupy in the history of Hungarian music, and how was the ballet and its music received by contemporaries in and out of the limelight? This study attempts to answer these questions by examining contemporary Hungarian and German news articles and music critiques published in Budapest.

This study examines the earliest data of the history of the organ in Transylvania collected in the past one hundred and fifty years. A thorough examination proved that data, based on incomplete documentation, on erroneous hypotheses or conclusions, had been quite unprofessionally put into contexts to which they had no proven connection. Thus, legends regarding the first representation of an organ, the first organ, the earliest organ builders etc. appeared in the costume of historicity and were widely circulated among different authors.
Attilio Ariosti as a Composer of Vocal Duets
Authors: Ćurković Ivan
Published: December 2022

In the first seasons of the Royal Academy of Music in London, its directors saw George Frideric Handel as one among several composers whose style reflected expectations of what Italian opera in London should be like. At one point, Handel’s slightly older Italian contemporaries Giovanni Bononcini and Attilio Ariosti were in equal positions to compete for success. This paper will focus on Attilio Ariosti as the seemingly most moderate party in the rivalry between the three composers to see if the specificities of the centers he was active in affected his output in the realm of the vocal duet, a less common and somewhat less important constituent of dramatic vocal genres as opposed to the dominant arias. The examination of duets in some of Ariosti’s works written for Berlin, Vienna, and London, and some comparisons with the duets by both Bononcini and Handel will shed a light on these relationships affected by competition and rivalry.

The spread of COVID-19 is still very high in Indonesia, especially in Eastern Indonesia. Inadequate facilities and the presence of health workers are still the toughest challenges in dealing with the spread of this virus. The low awareness of health protocols has led to various clusters of Covid-19 transmission in various places, including the orphanage. Real actions of concern at the Orphanage were carried out by educating on health protocols to prevent the COVID-19 pandemic from spreading to the residents of the Orphanage.

Solid-state fans (SSFs) have distinct advantages over traditional cooling fans in the thermal management of high-power electronics. In this work, a magnetic-field-enhanced SSF is proposed, and the physical model of negative corona discharge superimposed by an electromagnetic field is established. A computational model is used to calculate and analyze the effect of the magnetic field on the ionic wind distribution. The magnetic flux density and permanent magnet position distribution in the SSF are optimized experimentally, and the optimized SSF is applied to LED chip cooling. The findings show that adding a magnetic field encourages electrons to collide with neutral gas molecules and enhances the driving force of charged particles. The ionic wind velocity and mean driving force at the SSF's outlet will grow as magnetic flux density rises, and the ionic wind flow distribution will show apparent divergence. When the permanent magnet spacing is 15 mm, the highest ionic wind velocity is 2.82 m/s, and the mean driving force of SSF increases by 30.2%. The magnetic-field-enhanced SSF has a better LED-chip cooling effect, the maximum junction temperature drop is 11.6°C, and the cooling efficiency is higher. This research introduces a novel way of improving the cooling of electronics.
REDUCTION OF TOTAL DRAG FOR FINITE CYLINDERS IN TURBULENT FLOW WITH A HALF-C SHAPE UPSTREAM BODY

Published: December 2022

The effect of an upstream half-C shape body on the reduction of the total drag of a finite circular cylinder is investigated experimentally. Five main cylinders, each with an upstream half-C shape body placed at five upstream positions, a total of 25 different configurations, are considered during the experimentation at a Reynolds number in the range of 1.2 × 104 to 1.6 × 105. The aspect ratios of the main cylinders are 1.25, 2.09, 3.03, 3.78, and 4.90 and the upstream bodies are taken as 90° peripheral cut-outs of the respective main cylinder. The total configuration drag coefficient is calculated from the time-averaged drag force on the configuration and compared with the drag coefficient of the respective main cylinder. Results suggest that at least 20% of the total drag of the configuration might be reduced with the upstream half-C shape body, and the reduction varies with the main cylinders' aspect ratio and the upstream body placement distance. The maximum drag reduction is about 55% if the half-C shape body is placed at an upstream distance of 66% of the main cylinder diameter with an aspect ratio of 3.03 and at a Reynolds number of 1.8 × 104. A critical distance ratio is found beyond which drag cannot be reduced by the upstream half-C shape body, and the attribution might be given to a formation of intermittent swirling flow in the cavity mode.
NON-SIMILAR MIXED CONVECTION ANALYSIS FOR MAGNETIC FLOW OF WILLIAMSON NANOFLUID OVER VERTICALLY STRETCHING SURFACE SUBJECTED TO VISCOUS DISSIPATION, POROUS MEDIA, AND HEAT SOURCE/SINK

Published: December 2022

The intention of this study is to explore the impact of non-similar modeling on mixed convective Williamson magnetized nanofluid flow over a vertically placed stretching surface with the consideration of engine oil as the base fluid and molybdenum disulfide (MoS2) as nanoparticles. The features of viscous dissipation, Darcy resistance, and heat source factor are also incorporated to examine the thermal prospective. The considered flow phenomenon is designated in the form of governing partial differential equations (PDEs) by employing the concepts of Boussinesq approximations and the boundary layer approach. By introducing non-similar transformations, the governing system is redesigned into dimensionless, non-similar, nonlinear PDEs. The dimensionless, non-similar framework is examined analytically by implementing local non-similarity and then stimulated numerically via bvp4c to explore the impacts of vital parameters on velocity and temperature distribution. The velocity distribution, temperature field, local Nusselt number, and drag force are elaborated through graphs and tables by altering the inputs of emerging parameters. The computations illustrate that the escalating inputs of the magnetic field and porosity parameter appear as the hindering factors against flow velocity. It is also discovered that with the rising estimations of nanoparticles, volume fraction leads an enhancement in the temperature distribution and decline in velocity profile. Furthermore, in a restricted case, the validity of results is found to be in good agreement with the published literature. A suitable range of stable solutions is obtained for emerging parameters. To the best of our knowledge, it is the first time that the non-similar analysis for the considered problem is reported. This work is anticipated to offer crucial data for the development of novel heat transfer devices in the future and serve as an incredible resource for the researchers studying nanofluid flows under various assumptions.

Authors: Sokolov Pavlo , Virk Muhammad S.
Published: December 2022

A study of dry ice growth on bundled (duplex) cylinders has been performed using icing wind tunnel experiments and computational fluid dynamics (CFD) numerical simulations. The aim of this study is to "fill the gaps" in the works of Wagner (2010) and Qing et al. (2018). The numerical simulations cover a range of possible icing conditions by varying the operating wind speed, median volume diameter, and for some cases-the angle of incidence between the cylinders. The obtained results for the 0° AoA show that the accreted ice masses ratio between the leeward and windward cylinder varies from ~ 100% to ~ 30%. The accreted ice masses ratio decreases with the increase in the wind speed and/or median volume diameter. For the cases with non-zero AoA, the accreted ice masses become approximately equal, when the AoA is large enough to produce a vertical separation equal or greater to one cylinder diameter.

Published: December 2022

Aiming at the problems of asphalt pavement crack sealing and pothole repair materials, an epoxy-resin adhesive with high forming strength, good toughness and room-temperature curing was prepared. In addition to being used as a road filling sealant, the adhesive can also be used for preparing a cold patching mixture for pits. The properties of the epoxy-resin adhesive, the construction performance and road performance of the pouring sealant and cold patch were studied. The results showed that the early strength of the epoxy-resin adhesive was fast and high, the curing volume shrinkage was small, the low-temperature characteristics and tensile properties were good, and the toughness was excellent. As a pouring sealant, the epoxy-resin adhesive had excellent low-temperature bending resistance. The cold patching mixture based on the adhesive exhibited strong cohesiveness, good low-temperature crack resistance, and excellent high-temperature stability and water stability. This adhesive expands the application of epoxy resin in repairing cracks and pits of asphalt pavements, and is of great significance in promoting the development of the asphalt pavement maintenance technology.
MECHANICAL BEHAVIOUR OF INFLORESCENCE/GLASS-FIBRE-REINFORCED HYBRID EPOXY COMPOSITES

Published: December 2022

The biodegradability and environmental friendliness of natural fibres makes them suitable for implementation in a circular economy. As a result, several natural fibres and processing methods have evolved. The hydrophilic nature of ligno cellulose fibrils restricts the effective adhesion at the interface of fibre and matrix. The hybridization of natural fibres with synthetic fibres leads to promising characteristics of the resulting composite materials. This paper deals with the hybridization of conventional glass fibre and natural fibre extracted from coconut inflorescence. The effect of hybridization on the tensile and flexural strengths of surface-modified inflorescence fibre with glass fibres was investigated. The composites were fabricated using a hand-layup technique by varying the inflorescence fibre and glass-fibre reinforcement composition by (5, 10, 15 and 20) %. A notable improvement in the tensile and flexural strengths of 193.65 MPa and 240.69 MPa was observed for 85 % of glass and 15 % of benzoyl-chloride-modified inflorescence-fibre-reinforced hybrid composites. The elimination of amorphous constituents in the inflorescence fibres was checked by XRD and FTIR analyses. A surface-morphology analysis of unmodified and benzoyl-chloride-modified inflorescence fibres revealed pores and cavity formation on the fibril walls. These composites with superior mechanical properties can be an alternative to synthetic fibre composites and ensure the implementation of a circular economy and sustainable manufacturing.

Published: December 2022

This research was focused on the homogeneous precipitation synthesis of a series of Eu3+ ion-activated ellipsoidal La2O2SO4 phosphors based on the La2(SO4)3-CO(NH2)2 reaction system. The structural identification, thermal analysis, morphology and luminescence properties of the as-prepared products were characterized with Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetry and differential scanning calorimetry (TG/DSC), field emission scanning electron microscopy (FESEM) and photoluminescence (PL) spectra. Pure La2O2SO4 ellipsoidal particles with a long radius of about 2 µm and a short radius of about 1 µm were successfully prepared by calcining a rhombus-like precursor at 800 °C for 2 h in air. The formation mechanism of the precursor and its corresponding calcination product were also proposed. Photoluminescence results revealed that the strongest red emission peak was centered at 619 nm upon 249-nm ultraviolet (UV) light excitation in La2O2SO4:x%Eu3+ (x = 3, 6, 9, 12 and 15) phosphors. The exchange interaction was responsible for the concentration quenching mechanism of the 5D0→7F2 transition of Eu3+ ions in the La2O2SO4 host lattice. The optimal x value was 15 and the corresponding decay process showed a single exponential decay behavior whose lifetime t and color correlation temperature (CCT) were calculated to be 2.112 ms and 2752 K, respectively.

Il tessuto adiposo ectopico e quello perivascolare possono diventare un fattore di rischio cardiovascolare per l’ingresso all’interno del tessuto stesso di molecole infiammatorie Questa trasformazione del tessuto adiposo può favorire la progressione di malattia in organi e vasi e particolari situazioni cliniche come la fibrillazione atriale, lo scompenso, la vasculopatia cerebrale e la malattia coronarica. La radiomica che è una nuova e più avanzata tomografia computerizzata, permette di qualificare e quantificare il tessuto adiposo cosi trasformato. Essa permette inoltre una migliore definizione del rischio cardiovascolare e permette di inquadrare la malattia aterosclerotica già in una fase precoce favorendo, se necessario, un trattamento terapeutico, altrettanto precoce.
I grandi cardiologi. Omaggio ad Attilio Maseri
Authors: Marzilli Mario
Published: December 2022

Quando Attilio Maseri arrivò a Pisa, dopo un periodo di intensa attività scientifica in alcune delle più prestigiose Università americane, io ero al 5° anno di Medicina, allievo interno dell’Istituto di Patologia Medica, diretto dal Prof. Luigi Donato. Passarono pochi giorni e il Direttore mi chiamò per dirmi che ero stato assegnato al gruppo del Prof. Maseri, denominato Gruppo Coronarico e che il Gruppo si sarebbe dedicato allo studio della Fisiologia Clinica del circolo coronarico. Ne fui felice, anche se non potevo ancora immaginare quale privilegio mi fosse toccato. E l’avventura cominciò subito, appena venne aperta l’Unità di Terapia Intensiva Coronarica dell’Istituto di Fisiologia Clinica del CNR, con Attilio come Direttore. Attilio ci insegnò che non c’è mai nulla di scontato e che quello che “non tornava” era molto più stimolante di quello che tornava. E lavorando in UTIC con occhi “wide open”, di cose che “non tornavano” ne capitavano tutti giorni.
