EUROPEAN FOOTBALL AND THE COVID-19 PANDEMIC – ITS IMPACT ON COMPETITIONS, CLUBS AND PLAYER CONTRACTS
Authors: Davies Chris , Dunbar Neil
Published: March 2022

European football, like all major sport around the world, was heavily impacted by the COVID-19 pandemic. All national leagues in Europe had to suspend their 2019-20 seasons, though most were eventually able to complete them by extending the seasons beyond their usual finishing dates. However, these resumed fixtures had to be played in empty stadiums, as were most matches in the 2020-21 seasons. This article considers how these problems were dealt with by investigating the three key areas of competitions, the clubs and player contracts. UEFA, and the governing bodies of the various national leagues, demonstrated flexibility and adaptability in running the competitions which was crucial to their successful completion. The clubs suffered from loss of revenue due to reduced broadcasting rights and gate receipts but did obtain some financial assistance from a variety of sources. Player contracts had to be dealt with on a more individual basis depending on the law applicable to them and the negotiations between the individual clubs and their players, although there were national agreements in some countries. In the circumstances, European football appears to have survived the COVID-19 pandemic reasonably well, although the recent advent of the Omnicron variant indicates that the problems may not be over yet.
Xul Solar: perspectivas historiográficas e imagen técnica
Authors: Bucari Agustín
Published: March 2022

El artículo propone una revisión sobre la producción de Xul Solar (1912- 1924), incorporando aportes de las distintas corrientes que componen el campo heterogéneo de la llamada ciencia de la imagen. El desarrollo parte de la premisa de ubicar a la imagen técnica en el centro del análisis —sus usos, manipulaciones, reformulaciones de las imágenes extrartísticas en la obra de artistas modernos relevantes—, para esbozar las complejas movilidades entre los campos artísticos y científicos a principio del siglo xx. Para ello se dispone una metodología cercana a la iconografía crítica y se privilegia la recuperación de una mirada técnica moderna y de estrategias de montaje que se expresan en los dos paneles que corren paralelos al texto.

Neurological manifestations and etiological risk factors in patients hospitalized with COVID-19 in Turkey
Authors: Usta Nuray Can , Kartal Seyfi , Gunay Betul Onal , Boz Cavit
Published: March 2022

Background

Coronavirus disease 2019 (COVID-19) can affect the neurological as well as the respiratory system. Neurological manifestations may involve the central or peripheral nervous systems, or musculoskeletal system. Findings can range from mild presentations, such as headache and anosmia, to severe complications, such as stroke and seizure.

Objectives

To evaluate the neurological findings and to determine etiological risk factors for mortality in patients hospitalized for COVID-19.

Methods

Medical records of patients with COVID-19 who were hospitalized and sought neurological consultation between March 2020 and March 2021 at a reference pandemic hospital in Turkey were reviewed retrospectively in a cross-sectional study design.

Result

We included data from 150 (94 male) patients. Their mean age ± standard deviation was 68.56 ± 16.02 (range 21–97) years. The patients were categorized into 2 groups according to any acute neurological event or progression of neurological disease. Ischemic cerebrovascular events, seizures, and encephalopathy were the most common acute neurological events, while deterioration in consciousness, epileptic seizures, and Parkinson disease were observed in those with progression of neurological disease. Abnormal neurological findings were found at a mean of 7.8 ± 9.7 days following COVID-19 diagnosis and 50 (a third of) patients died. A logistic regression model found that advanced age, increased Modified Charlson Comorbidity Index (MCCI) score, and prolonged duration of hospitalization were factors significantly associated with increased mortality; however, sex and day of abnormal neurological findings after COVID-19 diagnosis were not. Common conditions accompanying neurological events were hypertension, coronary artery disease–heart failure, and diabetes mellitus.

Conclusion

COVID-19 may present with neurological symptoms in our Turkish patients and comorbidities are often present.
Considerations Regarding the Solutions for Heating and Cooling of Cult Buildings
Authors: Branca Ionut-Cristian
Published: March 2022

Religious art, expressed through the architecture and painting of churches, is subject to the action of time, requiring preservation of the architectural and artistic heritage throughout their existence by providing adequate microclimate parameters.

Functional and constructive particularities of cult buildings – large volumes constructed, high thermal inertia of the envelope elements and periodically occupied spaces with variable occupant – influence the conditions of conformation and operation of the heating and air conditioning systems.

The determination of the calculation parameters and the conformation of the installation systems must take into account these particularities and consequences leading to the necessity to provide some installations with low functional inertia.

The report presents an adequate method of calculation based on the thermal balance of the air in the enclosure and the envelope space, under the conditions of cyclical operation and with limited duration of the installations.

The paper is within the thematic context of the doctoral thesis “Energy efficiency solutions for heritage buildings”
Photovoltaic Systems Maximum Power Point Tracking Algorithms
Authors: Cercel George , Tigănaşu Cosmin , Nemeş Ciprian
Published: March 2022

The power delivered by a photovoltaic cell generator depends on the operating point at which this works. In order to maximize the energy supplied by the PV system, the generator should be adapted to the load so that the operating point will always correspond to the maximum power point. Usually, when a PV module is connected directly to a load, its operating point is rarely at the maximum power point. The operating principle of the maximum power point tracking is to place a converter between the load and the PV array, to adjust the output voltage and the current of the PV array so that the maximum available power is extracted. In most cases the optimal algorithm is chosen according to several criteria, such as: implementation complexity (autonomy of the systems, connected to the network), the type and number of sensors needed, the ability of the algorithm to detect local maximum points, cost, response time, type of implementation (analog, digital, mixed).

Published: March 2022

The paper presents a new eye image segmentation method used to extract the pupil contour based on the modified U-Net CNN architecture. The analysis was performed using two databases which contain IR images with a spatial resolution of 640x480 pixels. The first database was acquired in our laboratory and contains 400 eye images and the second database is a selection of 400 images from the publicly available CASIA Iris Lamp database. The results obtained by applying the segmentation based on the CNN architecture were compared to manually-annotated ground truth data. The results obtained are comparable to the state of the art.

The purpose of the paper is to present the implementation of a robust segmentation algorithm based on the U-Net convolutional neural network that can be used in eye tracking applications such as human computer interface, communication devices for people with disabilities, marketing research or clinical studies.

The proposed method improves uppon existing U-Net CNN architectures in terms of efficiency, by reducing the total number of parameters used from 31 millions to 38k. The advantages of using a number of parameters approximatly 815 times lower than the original U-Net CNN architecture are reduced computing resources consumption and a lower inference time.

Authors: Barros Barbosa Diego , Luiz Ana Paula , Gutierrez Fernandes Beati André Augusto , Lúcia Damasceno de Oliveira Laira
Published: March 2022

A contaminação das águas por compostos químicos complexos, tais como os fármacos têm causado grande preocupação entre os ambientalistas, devido à sua elevada persistência em meio aquoso e por não serem removidos de forma eficiente por sistemas convencionais de tratamento de água. Desse modo, este estudo buscou avaliar o potencial da casca de banana na remoção do fármaco diclofenaco sódico na água através do processo de bioadsorção. Para tanto, foi avaliada a toxicidade do fármaco através de dois ensaios de fitotoxicidade utilizando como organismo-teste sementes de Lactuca sativa (alface), onde os parâmetros avaliados foram o número de sementes germinadas e o crescimento das radículas, sendo que tais bioensaios foram realizados antes e depois dos testes de bioadsorção. Além disso, foi realizado a análise de DQO das amostras estudadas. Foram testadas duas amostras de água (CB1 e CB2) contendo diclofenaco na concentração inicial de 0,375 g/l com o bioadsorvente casca de banana em diferentes quantidades, (m = 0,5 e 1,0 g), respectivamente, através da agitação das amostras e posterior filtração à vácuo. A partir dos resultados obtidos, foi possível verificar que o fármaco analisado pode causar efeitos negativos ao crescimento das radículas e germinação das sementes de alface a partir de uma concentração de 0,375 g/l. Entretanto, constatou-se um aumento significativo no crescimento (88,7% e 89,2%) e germinação (8,7% e 12,5%) das radículas com as amostras tratadas (CB1 e CB2). Ademais, houve aumento significativo da DQO das amostras tratadas em relação as amostras brutas. Concluiu-se que, são necessários estudos mais aprofundados acerca da redução da toxicidade e do potencial de remoção do diclofenaco sódico na água através do bioadsorvente casca de banana em um processo de bioadsorção.

Virus are a common cause of aseptic meningitis. In most cases (90%) the etiological agent is enterovirus, followed by arbovirus, HIV, adenovirus, influenza and the viruses of the Herpesviridae family. These include herpes simplex, which causes approximately 0.5% to 3% of aseptic meningitis, with herpes simplex 1 being the most frequent in this group. Human herpesvirus-6 (HHV-6), in rare cases, may also be associated with meningitis in combination with exanthema subitum. This report aims to present a rare case of meningoencephalitis caused by HHV-6 in an infant. In the present case, we have a male infant, 1 year and 2 months old, with a previous history of seizure and delayed neuropsychomotor development, referred to a tertiary hospital after a prompt evaluation with complaint of fever, irritability, somnolence and vomit-ing with 7 days of evolution. Analysis of cerebrospinal fluid with PCR positive for HHV-6. He was discharged in good general condition after 14 days of correct drug treatment. HHV-6 infection is often underdiagnosed because it has few specific symptoms. The etiologic identification is rec-ommended in children with atypical manifestations or immunodeficiency, allowing adequate treatment in an early manner, in order to avoid complications and mainly neurological sequelae.

Objetivo: Discutir os aspectos legais envolvidos na emissão dos atestados de óbito e suas facetas sob o ponto de vista do direito médico brasileiro. Revisão bibliográfica: É imprescindível o conhecimento de como preencher corretamente a Declaração de Óbito. Entretanto, observa-se que, no meio médico, há erros ou dúvidas no momento desse ato, uma vez que se constitui um tema negligenciado em algumas escolas médicas brasileiras e pouco revisto ou treinado em hospitais e programas de residência médica. Além disso, os resultados mostraram que alguns médicos não utilizam expressões corretas ao relatar as causas do óbito no prontuário ou em seus relatórios. Considerações finais: A menor procura e capacitação do correto registro dos atestados de óbitos induz a maiores taxas de diagnósticos inespecíficos acerca da causa primária e causas consequenciais do óbito e outros impasses do seu uso para fins epidemiológicos.  Portanto, torna-se imprescindível a abordagem deste conceito durante e após a formação acadêmica do médico, com o fito de estimular o reconhecimento da sua importância tanto legal quanto em saúde pública.

Authors: Abadi Muhammad Arya Setiawan , Amir Mohammad Faizal
Published: March 2022

The purpose of this study was to analyze the types (concepts, principles, and verbal) and forms of difficulties that elementary school students did in solving problems of perimeter and area of plane figures based on their level of completion ability. This research method is qualitative with a case study type. The technique of taking research subjects used purposive sampling by selecting three subjects of fifth-grade elementary school students based on the level of mathematical ability (low, moderate, and high) in solving perimeter and area of plane figures. Data collection techniques using tests and interviews. Data analysis techniques include data reduction, data presentation, and concluding. The results showed that students with low levels of ability experienced verbal difficulties in not working on the questions according to the instructions. Students with a moderate level of ability face conceptual difficulties in the form of being unable to make relevant decisions according to the requirements of the questions. In addition, students experience principle difficulties in the form of an inability to determine the relevant factors and incorrectly using the perimeter unit for the area unit. Students with a high level of ability experience principle difficulties in using formulas, so they tend to experience inaccuracies in solving problems. Other findings in this study provide that elementary school students have difficulty solving problems of perimeter and area of a plane figure because of basic problems, namely experiencing obstacles in verbal problems and inadequate conceptual knowledge.

In contrast to the extensive but non-recyclable use of tetraalkoxydiboron(4) compounds as stoichiometric reagents in diverse reactions, this article reports an atom-economical reaction using a commercial diboron(4) as the catalyst. The key to success was designing a catalytic cycle for radical [3+2] cycloaddition involving a pyridine cocatalyst to generate from the diboron(4) catalyst and reversibly mediate the transfer of boronyl radicals. In comparison with known [3+2] cycloaddition with transition metal-based catalysts, the current reaction features not only metal-free conditions, inexpen-sive and stable catalysts, and simple operation, but also remarkably broadened substrate scope. In particular, previously unusable cyclopropyl ketones without an activating group and/or alkenes with 1,2-disubstitution and 1,1,2-trisubstitution pattern were successfully used for the first time. Consequently, challenging cyclopentane compounds with various levels of substitution (65 examples, 57 new products, up to six substituents at all five ring atoms) were readily prepared in generally high to excellent yield and diastereoselectivity. The reaction was also successfully applied in con-cise formal synthesis of an anti-obesity drug and building natural product-like complex bridged or spiralcyclic com-pounds. Mechanistic experiments and computational investigation support the proposed radical relay catalysis featuring a pyridine-assisted boronyl radical catalyst. Overall, this work demonstrates the first approach to use tetraalkoxydibo-ron(4) compounds as catalysts and may lead to the development of new, green and efficient transition metal-like boron-catalyzed organic reactions.
Hydrogen Bond Redistribution Effects in Mixtures of Protic Ionic Liquids Sharing the Same Cation: Nonideal Mixing with Large Negative Mixing Enthalpies
Authors: Golub Benjamin , Ondo Daniel , Overbeck Viviane , Ludwig Ralf , Paschek Dietmar
Published: March 2022

We report a joint experimental and theoretical study characterising the hydrogen bond (HB) redistribution in mixtures of two different protic ionic liquids (PILs) sharing the same cation: triethylammonium-methanesulfonate ([TEA][OMs]) and triethylammonium-trifluoromethanesulfonate ([TEA][OTf]). The mixing behaviour deviates strongly from ideality, exhibiting large negative energies of mixing. In the PIL, the [TEA] cation acts as a HB donor, being able to donate a single HB. Both, the [OMs] and the [OTf] anions can act as HB acceptors, which can accept multiple HBs via their respective SO3-groups. We use a combination of molecular dynamics (MD) simulations, calorimetry, and $^1$H-NMR chemical shift measurements to determine the difference in HB strength between the two species to be about 13 kJ/mol, favouring the [TEA]-[OMs] interaction. Based on our MD simulations we are able to formulate a lattice model, discriminating between HB and nonspecific intermolecular interactions. We demonstrate that, due to the ordered structure of the PILs, only the HB interactions contribute to the mixing energy. This allows to us to connect the equilibrium of HBs to each of the two anion species with the mixing energies by a simple relation, which is obeyed by both, MD-simulation as well as experimental calorimetry and 1H-NMR chemical shift data.

Published: March 2022

The rate of road traffic accidents in the 38th and 39th week of 2020 has increased. Many factors influence the occurrence of accidents, one of the reasons is that the driver is sleepy. The parameters used to determine the condition of drowsiness are identifying the condition of the eyelids. With this identification, an image processing system can be utilized by applying the Haar Casecade Classifier and Circular Hough Transform methods with Find Countur using HSV parameters. The detection uses a camera with the driver's eye input, if the image detected is a drowsy eye, the system will wake up the driver by turning on a sound alarm, besides this system is equipped with an SMS gateway feature that will be sent to the driver's relatives, that the driver is sleepy. Message notification sent contains the condition and location of the rider. Based on system-wide testing, this system has a success rate of 100% against HSV1, 96% against HSV2 and HSV3, 89% against HSV4, and 88% against HSV5 on eye detection results and response time. The resulting error is because the lighting at a certain distance is not match with HSV set, the system experiences a freeze due to the buzzer sound delay that is too long and the performance of the PC is also less than optimal.

Authors: 建国 赵
Published: March 2022

论文针对煤矸石大量堆积占用土地、污染环境等问题，制备了水泥稳定煤矸石-碎石路面基层混合料，进行了击实试验、无侧限抗压强度试验和劈裂强度试验。试验结果表明：随着煤矸石替代率的增加，试件的最佳含水量增大，最大干密度降低，混合料的强度呈减小趋势，表明煤矸石的掺入对混合料的无侧限抗压强度和劈裂强度有不利影响。随着养生龄期的延长和水泥掺量的增大，混合料的强度呈增长趋势。7d龄期时，水泥掺量为5%，煤矸石替代率为50%时，混合料的无侧限抗压强度达到4.81MPa，满足中国二级及二级以下公路的技术要求。根据试验结果，建立了混合料的无侧限抗压强度和劈裂强度之间的关系模型。

Factors Affecting Switching Intention from Cash on Delivery to E-Payment Services in C2C E-Commerce Transactions: COVID-19, Transaction, and Technology Perspectives
Authors: Purwandari Betty , Suriazdin Syahrul Alam , Hidayanto Achmad Nizar , Setiawan Suryana , Phusavat Kongkiti , Maulida Mutia
Published: March 2022

During the COVID-19 pandemic, the application of e-payment has rapidly increased. However, e-payment has not been able to achieve a trustworthy level in e-commerce transactions. Thus, cash payment methods with Cash On Delivery (COD) services still dominate C2C e-commerce payment transactions in Indonesia. This study aims to investigate factors that affect users' switching intentions from COD to e-payment services. The research model was adopted by using the Push-Pull-Mooring framework, integrating perceived COVID-19 risk, technology acceptance, and transaction effort. Empirical research was conducted using data from 546 COD and e-payment users in Indonesia, with Structural Equation Modelling (SEM) being used to validate the model and analyze the hypotheses. The results indicate that switching intention from COD to e-payment is significantly influenced by pull factors in e-payment, which are economic benefits, performance expectancy, effort expectancy, and critical mass. There are also two mooring factors that significantly influence the switching intention from COD to e-payment, which are trust and perceived security and privacy. This study makes a significant contribution to the literature in terms of validating a theoretical framework that emphasizes factors that influence user switching intentions from COD to e-payment in the context of the COVID-19 pandemic. This research can be a reference for Indonesian payment system regulators and e-payment service providers in formulating regulations and strategies to accelerate the spread of digital transactions in Indonesia. Doi: 10.28991/esj-2022-SPER-010 Full Text: PDF
