Europäische Ordnungspolitik im Wettbewerb mit China
Authors: Bardt Hubertus , Matthes Jürgen
Published: August 2021

Die Transformation der chinesischen Planwirtschaft seit der Öffnung 1978 hat zu erheblichem Wohlstand, einer umfassenden Modernisierung und einer global wettbewerbsfähigen, teilweise führenden Wirtschaft geführt. Mit dem Beitritt zur WTO hat sich China weiter in die marktwirtschaftlich geprägte Weltwirtschaft integriert. Dennoch hat sich die chinesische Wirtschaftsordnung nicht zu einer Marktwirtschaft westlicher Prägung entwickelt, sondern mit dem Staatskapitalismus eine eigene Form jenseits von Markt- und Planwirtschaften etabliert. Die daraus resultierenden unterschiedlichen Verhaltensweisen (z. B. staatliche Eingriffe, Subventionen, Technologietransfer) können zu Wettbewerbsverzerrungen auf internationalen Märkten führen. Durch das wirtschaftliche Gewicht Chinas, haben diese Wettbewerbsverzerrungen erhebliche Relevanz gewonnen. Die Europäische Union kann auf der Ebene der Handels-, Wettbewerbs- und Investitionspolitik agieren, um Verzerrungen entgegenzutreten und den Wettbewerb zu möglichst gleichen Bedingungen zu stärken.
Entscheidungspraxis des Bundeskartellamts im Bereich der Bundesliga-Übertragungsrechte
Authors: Dewenter Ralf , Klein Gordon J.
Published: August 2021

In der vorliegenden Arbeit wird die Entscheidung des Bundeskartellamts, ein sogenanntes Alleinerwerbsverbot für Bundesligaübertragungsrechte zu implementieren, kritisch beleuchtet. Wir argumentieren vor dem Hintergrund der wettbewerbsökonomischen Literatur zu vertikalen Beschränkungen, dass die Möglichkeiten potenzielle Wettbewerbsprobleme auf diese Weise zu lösen, sehr begrenzt sind. Stattdessen zeigt unsere Analyse auf, dass die Auflagen des Bundeskartellamts eine wohlfahrtsschädliche Wirkung haben. Die Entscheidung über die Einführung eines Alleinerwerbsverbots hätte in jedem Fall jedoch eine dezidierte Marktabgrenzung und Wettbewerbsanalyse erfordert.
Baker’s yeast (Saccharomyces cerevisiae) catalyzed synthesis of bioactive heterocycles and some stereoselective reactions
Authors: Banerjee Bubun , Singh Arvind , Kaur Gurpreet
Published: August 2021

Saccharomyces cerevisiae, commonly known as baker’s yeast, has gained significant importance as a mild, low-cost, environmentally benign biocatalyst. Initially it was mostly employed as an efficient catalyst for the enantioselective reduction of carbonyl compounds. Over the last decade, baker’s yeast has found versatile catalytic applications in various organic transformations. Many multicomponent reactions were also catalyzed by baker’s yeast. Various heterocyclic scaffolds with immense biological activities were synthesized by employing baker’s yeast as catalyst at room temperature. In this communication, we have summarized baker’s yeast catalyzed various organic transformations focusing primarily on heterocyclic synthesis.
Radiation attenuation properties of B2O3-ZnO-Al2O3-Bi2O3-Sm2O3 glasses
Authors: Eke Canel
Published: August 2021

The goal of this study is to examine theoretically radiation absorption properties of zinc alumino bismuth borate (BZnAlBiSm) glasses with chemical formula 60B2O3-9ZnO-(30-x)Al2O3-xBi2O3-1Sm2O3 where x = 5, 10, 15 and 20 mol%. The linear and mass attenuation coefficents of BZnAlBiSm glasses turn out as this trend BZnAlBiSm-1<BZnAlBiSm-2<BZnAlBiSm-3<BZnAlBiSm-4. The BZnAlBiSm-4 with the smallest half value layers, tenth value layers and mean free paths in the examined energy ranges has the superior radiation shielding characteristics among the BZnAlBiSm glasses. The BZnAlBiSm-4 glass has the highest radiation protection efficiency among the BZnAlBiSm glasses. The transmission factors increase as photon energy range enhances from 0.015 to 15 MeV and thickness declines from 2.5 to 0.5 cm. The energy buildup factors and energy absorption buildup factors of BZnAlBiSm glasses reduce from 15 to 1 mfp. Variation of the effective atomic number and effective electron density as a function of photon energy for BZnAlBiSm glasses are similar. The projected ranges of electron, proton, alpha and carbon for the BZnAlBiSm glasses increase as photon energy enlarges. The fast neutron removal cross sections of the BZnAlBiSm glasses vary in order of BZnAlBiSm-4<BZnAlBiSm-3<BZnAlBiSm-2<BZnAlBiSm-1. Thus, it can be concluded that BZnAlBiSm-1 has the highest neutron absorption ability among the BZnAlBiSm glasses.
Corona-Komposita und ‚Corona‘-Konzepte in der Medienberichterstattung in Standardsprache und in Leichter Sprache
Authors: Fuchs Julia
Published: August 2021

First linguistic studies have paid attention to the influence of the current corona pandemic on language use in the German media coverage. They have revealed, amongst other things, that compounds beginning with corona are very productive and frequent. Against this background, the questions arise how frequent these compounds de facto are, what their morphological and graphematic characteristics look like, which second constituents can be observed, which semantic relations between the constituents exist and what their referents are. However, not only people being able to read texts in standard language need information concerning the pandemic; individuals lacking this capacity also need to know which rules apply to public life and social interaction. Therefore, information on the corona pandemic is also available in German Easy Language. But translators are faced with several dilemmas regarding the translation of compounds into Easy Language. It is thus an open question whether compounds beginning with corona, recently observed in the media coverage in standard language, also occur in the media coverage in Easy Language and, if present, what their characteristics are in comparison to the relevant compounds in standard language. An additional question is how the referents of compounds beginning with corona in standard language are designated in Easy Language in those cases where no comparable compound beginning with corona is used for this purpose. The present study uses a corpus linguistic approach to address these questions.
Die Verantwortlichkeit des Geschäftsleiters für Datenschutzverstöße
Authors: Schmitt Florian
Published: August 2021

Unternehmen müssen im Rahmen ihrer Geschäftstätigkeit regelkonformes Verhalten sicherstellen und nicht zuletzt die Vorgaben des Datenschutzrechts, insbesondere jene der noch jungen Datenschutz-Grundverordnung (DSGVO), einhalten. Im Innenverhältnis fällt es in die Verantwortlichkeit des Geschäftsleiters (des Vorstands der AG bzw. des Geschäftsführers der GmbH), für eine ordnungsgemäße Compliance-Organisation im Unternehmen zu sorgen. Diese hat sich auch auf das Datenschutzrecht zu erstrecken. Der Beitrag geht der Frage nach, ob ein Verstoß gegen datenschutzrechtliche Vorschriften – jenseits der Haftung des Unternehmens und über die Innenhaftung des Geschäftsleiters wegen Verletzung seiner Compliance-Verantwortung hinaus (§ 93 Abs. 2 AktG, § 43 Abs. 2 GmbHG) – zu einer Außenhaftung des Geschäftsleiters gegenüber Dritten führen kann. Zudem untersucht er, ob die Verhängung einer Geldbuße gegen den Geschäftsleiter möglich ist und ob die Gesellschaft den Geschäftsleiter im Hinblick auf eine gegen sie verhängte Geldbuße in Regress nehmen kann.
Gemeinschaftliche Gesamtvermögenshaftung

Published: August 2021

Zur Besprechung gelangen zwei Urteile, in denen der BGH implizit entschieden hat, dass die in §§ 128, 171 HGB angeordnete Außenhaftung der Personengesellschafter infolge teleologischer Reduktion eine bedeutende Ausnahme erfährt: Sie soll sich nicht auf solche Gesellschaftsschulden erstrecken, die erst während des Insolvenzverfahrens der KG entstanden sind, sofern deren Rechtsgrundlage nicht bereits vor Verfahrenseröffnung begründet war. Die vorliegende Rezension kritisert diese Rechtsfortbildung: §§ 128, 171 HGB lassen weder in diesem noch in anderen prominent diskutierten Fällen eine teleologische Reduktion zu.

Published: August 2021

The introduction of new animals into hunter-gatherer societies produces a variety of cultural responses. This article explores the role of rock art in western Arnhem Land, Australia, in helping to mediate contact-period changes in Indigenous society in the nineteenth century. The authors explore etic and emic perspectives on the ‘re-emergence’ of water buffalo into Aboriginal cultural life. Merging archaeological analysis, rock art and ethnographic accounts, the article demonstrates how such artworks were used as a tool for maintaining order in times of dramatic social change. The results of this research have significant implications for understanding how cultural groups and individuals worldwide used rock art during periods of upheaval.

Published: August 2021

Objective

Increased visceral fat and sarcopenia are cardiovascular risk factors that may explain increased cardiovascular morbidity and frailty in patients with adrenal adenomas. Our objective was to compare body composition measurement of patients with adrenal adenomas to referent subjects without adrenal disease.

Design

Cross-sectional study, 2014–2018.

Methods

Participants were adults with nonfunctioning adrenal tumor (NFAT), mild autonomous cortisol secretion (MACS), and Cushing syndrome (CS) and age, sex, and BMI 1:1 matched referent subjects without adrenal disorders. Main outcome measures were body composition measurements calculated from abdominal CT imaging. Intra-abdominal adipose tissue and muscle mass measurements were performed at the third lumbar spine level.

Results

Of 227 patients with adrenal adenomas, 20 were diagnosed with CS, 76 with MACS, and 131 with NFAT. Median age was 56 years (range: 18–89), and 67% were women. When compared to referent subjects, patients with CS, MACS, and NFAT demonstrated a higher visceral fat (odds ratio (OR): 2.2 (95% CI: 0.9–6.5), 2.0 (1.3–3.2), and 1.8 (1.2–2.7) and a lower skeletal muscle area (OR: 0.01 (95% CI: 0–0.09), 0.31 (0.18–0.49), and 0.3 (1.2–2.7)) respectively. For every 1 µg/dL cortisol increase after overnight dexamethasone, visceral fat/muscle area ratio increased by 2.3 (P = 0.02) and mean total skeletal muscle area decreased by 2.2 cm2 (P = 0.03).

Conclusion

Patients with adrenal adenomas demonstrate a lower muscle mass and a higher proportion of visceral fat when compared to referent subjects, including patients with NFAT. Even a subtle abnormality in cortisol secretion may impact health of patients with adenomas.
Condición ambiental del sedimento del sector oriental del golfo de Cariaco
Authors: Fuentes Hernández María Valentina
Published: August 2021

En 2008, se evaluó la condición ambiental del sedimento de la región oriental del golfo de Cariaco (Venezuela) al relacionar las concentraciones químicas de metales traza e hidrocarburos policíclicos aromáticos (HAP) con las respuestas a pruebas toxicológicas estandarizadas. Para ello, en abril, los metales particionados en el sedimento y en el agua retenida fueron extraídos y medidos con ICP-OES. Los HAP fueron separados del sedimento con ultrasonido y medidos con HPLC-fluorescencia. Además, se ejecutaron pruebas de supervivencia de Artemia y actividad hemolítica. Las concentraciones de metales totales (µg g-1) fueron: Cu (29-91), Cd (1.9-4.9), Cr (4-36 ), Ni (10-33), Pb (3-9) y Zn (32-112). En el agua fueron detectados, en µg L-1: Pb (33-56) y Cr (154-237). Las concentraciones de HAP (3-5 anillos) fueron bajas, con predominio de fluoranteno (22-71 ng g-1), en particular, pirolítico. Solamente, en algunas localidades, las concentraciones de Cu, Ni y Cd del sedimento superaron los criterios de calidad. No hubo mortandad de larvas durante las pruebas toxicológicas y la actividad hemolítica fue menor que 2%. Una vez realizado el contraste se demuestra que los sedimentos tienen alta calidad ecológica.
Volunteering in Lithuania – the perspective of social capital
Authors: Staliūnas Justinas , Stasiukynas Andrius , Šukvietienė Aušra
Published: August 2021

The level of social capital in society is one of the most important elements for the success of state development, which is increasingly emphasized on political agendas. In research, social capital covers a wide range of areas due to the interdisciplinarity of social capital. Still, the dominant components stand out: trust in society, trust in public authorities, involvement in civic activities. While trust in public authorities and trust in other members of society are more often used in research and heard in the media, civic activities often lack such interest. However, it is one of the most effective ways for government decisions to invest most effectively in improving social capital in society. The primary tool for the state to increase public involvement in civic activities is the promotion of voluntary activities, which contributes to the state’s sustainable development, and the creation of the welfare state is enshrined in international documents. With this article, the authors seek to examine the peculiarities of Lithuanian volunteering in the context of social capital formation. The aim is to: 1) examine the theoretical assumptions of the impact of volunteering on the formation of social capital; 2) study the expression of social capital and voluntary activity in the context of state performance evaluation indicators; 3) carry out empirical research (expert interview) examining the peculiarities of volunteering in Lithuania. It should be noted that some of the results of the empirical research were used in the report of the applied research “Development of Youth Volunteering in Lithuania” (prepared by the Lithuanian Council of Youth Organizations (LiJOT) project “Strengthening the Participation of the Lithuanian Council of Youth Organizations in Public Management Decision Making”). The development of volunteering and the improvement of social capital indicators are named Lithuania’s long-term strategic goals, but the indicators in international indices are low compared to other countries.The analysis of the results of the empirical research allows us to state that: 1) In Lithuania, volunteering is often treated in various ways, e.g., in connection with unpaid work or other activities which are not, in principle, activities carried out of the person’s own free will; outstanding long-term and short-term volunteering (up to 6 months); 2) organizers of voluntary activities (usually non-governmental non-profit organizations (NGOs)) lack managerial skills; 3) In recent years, Lithuania has started to develop long-term volunteering programs, which are associated with better social capital formation, and it is expected that this measure will help to improve the quality and indicators of volunteering, especially among young people.

Therapeutic and organizational approaches to the patients with acute back pain management in outpatient practice (according experience of Croatia and Slovenia)
Authors:   Ternopil National Medical University named I. Ya. Gorbachevsky, Babinets L.S.
Published: August 2021

Acute low back pain is one of the most common health problems in family medicine. This pain is experienced at least once in the life of 60-80% of people. The aim is to analyze the European (Croatian and Slovenian) experience of medical and organizational approach to the management of a patient with acute back pain in the practice of a primary care physician. Main part. Treatment of low back pain should be comprehensive and not only pharmacological. An appropriate combination with other treatments is required. The patient should be well aware of the nature of his illness. In more patients, a course of treatment and a short hospital stay (up to two weeks) is prescribed by a family doctor. The main purpose of drug treatment is pain relief. Treatment begins with paracetamol, which effectively relieves low back pain, while side effects are very rare. If the effect is weak, use nonsteroidal anti-inflammatory drugs (not recommended for patients with gastric or duodenal ulcers). A small number of patients with acute low back pain develop chronic back pain, which is established as a diagnosis after clinical symptoms persist for six months. It is important to immediately diagnose patients who may initially develop chronic low back pain, which requires referral for additional diagnostic examination, physical therapy, and assessment for temporary or permanent disability. Conclusion: Acute low back pain is a disease in which more than 50% of patients recover within 14 days. 10% of them have chronic pain. Such patients put a serious burden on the family doctor and the health insurance system. These 10% of patients spend almost 90% of the resources allocated to the treatment of low back pain. Diagnosis of acute low back pain should be thorough, which will appoint an effective and rational scheme of management of such a patient in order to correct the clinical condition, pain relief and prevention of chronic acute back pain

Improving the effectiveness of teaching problematic issues of rheumatology at the stage of postgraduate education by integrating immunological knowledge
Authors:   Dniprovskiy State Medical University, Kuzmina A.P. , Lazarenko O.M. ,   Dniprovskiy State Medical University
Published: August 2021

Clinical immunology is becoming an increasingly important area, in terms of its widespread use, in the teaching of rheumatology in cycles of thematic improvement. Purpose: development of a new diagnostic and therapeutic strategy for teaching rheumatological aspects based on the use of immunological knowledge. Rheumatologists are well aware of the simultaneous identification of antibodies to nuclear and cytoplasmic antigens, which contributes to the differential diagnosis of autoimmune pathology. The three versions of the quests we compiled had ambiguous answers from specialists who were well acquainted with clinical rheumatological pathology. 90% of physicians gave the correct, complete answer to the proposed first option (according to the WHO recommendations for the determination of molecular markers). The second variant of the task included activated forms of lymphocytes with phenotype CD69+, CD3+ HLA-DR+, CD19+ CD38+, CD8+ CD38+. Only 50% of physicians answered that such a test reflects the functional state of activated T- and B-lymphocytes and is recommended for monitoring the course of the disease. The next version of the quest was created taking into account the direct functions of receptor structures. Almost all physicians consider it unnecessary to assess minor subpopulations in patients with autoimmune diseases. When interpreting the results of the immunogram, a dissociation syndrome is established — a discrepancy between the direction of changes in the interrelated immunological parameters. The value of dissociation syndrome is that the latter may indicate latent immune defects. With the rapid expansion of new classes of drugs, clinical practice has changed dramatically, this is what drew the attention of rheumatologists to the fundamental knowledge of immunology and mechanisms of action of biological drugs. It should be noted that in many European countries, immunology courses have been developed specifically for rheumatology practice. Thus, the introduction of rheumatological aspects based on the use of immunological knowledge, especially at the stage of postgraduate education, which will contribute to professional development and the development of a full-fledged fully developed personality of the doctor.

Authors: Orique Silvia Diana de Lima Silva , Hammes Lúcio Jorge , Moita Emanuel
Published: August 2021

Este trabalho tem o objetivo analisar a incidência de bullying em Escolas Públicas, verificando as ações da gestão em relação a esta violência, que presente no ambiente escolar e tem trazido graves consequências para quem a sofre. A pesquisa foi desenvolvida em duas escolas, sendo uma municipal e outra estadual, situadas no município de Jaguarão, Rio Grande do Sul. Nestas escolas foram desenvolvidas entrevistas com professores, equipes de gestão e pais, permitindo conhecer melhor a realidade das escolas, especialmente, as ocorrências de bullying. Os dados indicam que uma das escolas ainda não tem uma proposta efetiva voltada ao enfrentamento do bullying, ao passo que a outra já tem um trabalho em busca da cultura de paz, permitindo amenizar os efeitos das agressões. No ambiente escolar, buscar alternativas para reduzir o bullying é uma ação básica da educação.
Vocabulary of Catullus’ Poems Hapax Legomena as Vulgar Words
Authors: Adamik Tamás
Published: August 2021

“There are 150 words in Catullus which occur once only in his writings, and of these more than 70 per cent are rare in the whole of Latin literature, and more than 90 per cent do not occur in Vergil at all” – writes J. Whatmough in his work Poetic, Scientific, and other Forms of Discourse, Berkeley and Los Angeles, 1956, 41. It is necessary to distinguish between genuine and apparent once-words. The true once-word is a coinage that never recurs; the number of the true once-words is exceedingly small. Catullus’ once-words were well known, but not in writing. Theoretically one would expect such words to be polysyllabic; so are the comic jawbreakers of Aristophanes which fit the pattern of his verse so well. The hapax legomena of Catullus are not genuine once-words of the spoken language, but they are vulgar and in some contexte obscene. We can, therefore, regard them as taboo words. They occur sometimes in similes; cf. Poems 17, 23, 25, 97. In my paper I would like to analyse some vulgar hapax legomena of Catullus.
Oral Cavity Squamous Cell Carcinoma Presenting as an Isolated Nasal Mass in the Setting of a Fixed Implant–Supported Upper Denture
Authors: Civantos Alyssa , Rajasekaran Karthik
Published: August 2021

Proper staging and diagnosing of mucosal head and neck cancers is necessary given important differences in tumor behaviors that lead to different standards of treatment. We report the unusual case of a 65-year-old woman who is a former smoker with an implant-supported upper denture who developed an isolated nasal mass on examination, which was confirmed after resection to be a squamous cell carcinoma originating from the hard palate. Although this is a rare scenario, an oral cavity cancer should be taken into consideration in the differential diagnosis of a nasal cavity mass in the setting of a fixed upper dental implant.

Resultados A completude foi boa (94,1%); a aceitabilidade foi de 68,3%; o valor preditivo positivo foi de 10,7%; a representatividade foi de 98,4%; e a oportunidade ocorreu em 71,4% dos casos. Conclusão É possível concluir que o sistema de vigilância epidemiológica para a leptospirose em Campinas teve uma completude aceitável e bom percentual de suspeição da doença. Foram observados atraso na notificação e na investigação dos casos e precária integração entre os sistemas de informações. A avaliação do sistema de vigilância traz informações importantes para a organização dos serviços de saúde e deve fazer parte da rotina das ações previstas no sistema. Este trabalho pode ser usado como modelo para a avaliação de sistemas de informação de outras doenças de notificação compulsória.
Um Arquivo sobre Teatro e Educação: problematizações no campo da invenção
Authors: Gomes Sidmar Silveira
Published: August 2021

Resumo: Inspirada no trato arquivístico legado pelo pensador francês Michel Foucault, esta reflexão debruçou-se sobre a tarefa de estabelecer um inventário da produtividade discursiva relativa ao campo das práticas que aliam teatro e educação, tomando por base empírica artigos concernentes ao tema e publicados em 58 periódicos da área educacional. Objetivou-se flagrar descontinuidades, regularidades e aleatoriedades em tal campo discursivo, culminando em mirar pela perspectiva crítica o que no presente emana certo ar de naturalização. Tal inventário alumbrou discursos regulares, além de embates entre as ditas abordagens essencialistas e contextualistas das práticas teatrais, resultando em efeitos atenuadores de suas distâncias conceituais.
A Noção de Experiência na História da Sexualidade: implicações políticas e formativas
Authors: Pich Santiago
Published: August 2021

Resumo: O artigo trata do problema da experiência no terceiro domínio da obra de Michel Foucault, tomando como principal fonte os três primeiros volumes da História da sexualidade. Nele, analisa-se o lugar da experiência como uma categoria estruturante da obra e do pensar do intelectual francês, mostrando o caráter constitutivamente político dessa elaboração e os desdobramentos possíveis para pensar a formação humana. A experiência é concebida como um modo de relação consigo que implica a transformação de si a partir de uma lenta elaboração artesanal da própria existência, que se dá sempre na relação com o Outro, o que possibilita conceber a formação humana a partir da constituição ética-estética-política do sujeito nessa relação.

RESUMO Objetivo Avaliar a correlação entre o índice de desvantagem vocal e a qualidade de vida de cantores populares. Método Estudo transversal realizado com cantores populares. Os dados foram coletados por entrevistas presenciais, com aplicação dos instrumentos World Health Organization Quality of Life-bref (WHOQOL-bref), Índice de Desvantagem para o Canto Moderno (IDCM) e questionário de perfil sociodemográfico e de autopercepção de queixas. O nível de significância foi de 5% (p<0,05). Realizou-se análise descritiva por meio de frequências absolutas e relativas, média e desvio padrão. Variáveis quantitativas testadas por teste Komolgorov-Smirnov e testes não paramétricos Kruskal Wallis e U Mann-Whitney. A correlação entre os instrumentos WHOQOL-bref e IDCM foi realizada pela correlação de Spearman, a confiabilidade dos instrumentos foi testada pelo Alpha de Cronbach. Resultados Amostra composta por 206 cantores populares. Eles eram, em maioria, homens, solteiros, com escolaridade superior ou pós-graduação e renda de até seis salários mínimos. A maioria teve escores altos no WHOQOL-bref, indicando autopercepção de boa qualidade de vida. A maior parte dos cantores declarou ter queixas vocais. Aqueles que não apresentaram queixas tiveram autopercepção de melhor qualidade de vida e de menor desvantagem vocal, com significância estatística para todos os domínios do WHOQOL-bref e subescalas do IDCM. Cantores com melhores rendas e com faixa etária acima de 40 anos apresentaram melhor autopercepção de qualidade de vida e de menor desvantagem vocal. Houve correlação negativa e fraca entre o IDCM e o WHOQOL-bref. Conclusão Melhor qualidade de vida teve correlação com menor desvantagem vocal.

Reductions in materials consumption through the use of high-strength materials is important in building construction. However, high-strength steel applications have possible challenges such as their effects on bond behaviour and structural ductility. The bond behaviour, total energy capacity and failure modes of headed and straight high-strength and normal-strength steel bars were investigated using pull-out tests. In the experimental programme, 48 concrete specimens with a compressive strength of 40 MPa, different ratios of steel fibres and embedded steel bars with different yield strengths were subject to pull-out tests. The results showed that the headed bars had far greater bond stress and total energy capacity than the straight bars. It was also found that the higher the yield strength of the bars, the higher the energy capacity and bond stress. Although increases in fibre ratios led to increases in energy capacity, they did not absolutely increase the bond stress. The specimens with both headed and straight bars failed by splitting.
Prevalence of head and neck Myofascial Pain Syndrome in a South American population
Authors: Giraldo Rivera Olga Lucía
Published: August 2021

Objective: To diagnose the prevalence of Myofascial Pain Syndrome (MPS) with respect to sex, age, affected muscle, socioeconomic stratum, occupation and associated symptoms.

Methods: This is a descriptive, cross-sectional study of a convenience sample of 220 outpatients who attended the Faculty of Dentistry of the Universidad de Antioquia Medellín-Colombia, between September 30th, 2015 and September 7th, 2017. Interventions: not applicable. Main measure of results: Myofascial Pain Syndrome.

Results: 26.4% of our sample presented symtoms of MPS. More women than men were found to have MPS. The number of cases decreases with age. The most affected muscle is the trapezium, followed by the temporalis, and there are no significant differences in terms of socioeconomic stratum and occupation. The most frequently reported associated symptom is neck pain.

Conclusion: Because there is such a high prevalence, and on a global scale, we believe it is important to establish effective means of diagnosis and adequate measures for the prevention and treatment of this pathology.

Introducción: el propósito de esta investigación fue evaluar la microdeformación ósea del bruxismo con implantes dentales por medio del método de análisis de elementos finitos (FEA).

Materiales y métodos: se modeló un (1) implante Tapered Screw-Vent® (ref. TSVB10 Zimmer Dental) de 13mm de longitud x 3.7mm de diámetro con una plataforma de 3.5 mm, un pilar en Zirconio, un tornillo, agente cementante cemento de resina, una corona cerámica monolítica de un incisivo central superior, hueso cortical y hueso esponjoso, utilizando el Software CAD de Solid Works 2010 (SolidWorks Corp., Concord, MA, USA), y posteriormente se procesó y se analizó a través del Software ANSYS versión 14. Se evaluaron los esfuerzos von Mises y microdeformación ósea (µstrain), aplicando esfuerzos en sentido oblicuo con magnitudes de 200N y 800N. Este análisis permitió evaluar y comparar la (µstrain), tanto en el hueso cortical como en el hueso esponjoso en dos magnitudes 200N Y 800N.

Resultados: cada uno de los elementos de la estructura modelada (corona, pilar, tornillo, implante, hueso cortical y esponjoso) sometida al incremento de esfuerzos, presentó valores von Mises y µstrain particulares con un comportamiento lineal. Al someter la estructura modelada a esfuerzos de 200N y 800N, ninguno de los componentes sufrió deformaciones permanentes, es decir, no se superó el límite de fluencia.

Conclusión: de acuerdo al comportamiento mecánico de la estructura modelada en magnitudes de 800N, es posible la utilización de un implante dental en un incisivo central superior, debido a que las fuerzas parafuncionales generadas por el bruxismo no son superiores a las presentadas en la estructura modelada, en consecuencia, no generan deformaciones permanentes en el hueso.
Positive ecological roles of parasites
Authors: Szopieray Katarzyna , Żbikowska Elżbieta
Published: August 2021

The traditional assessment of parasites by veterinarians and medical professionals is une-quivocally negative. In this minireview, we focus on the positive aspects of the presence of parasites in the environment. Most notably, the host-parasite system is a long-term interac-tion because parasites, despite their negative impact on the host, rarely lead to its death. We analysed three important aspects of the presence of parasites in the environment: (i) participation in the regulation community balance leading to changes in the dominance structure, the formation of trophic chains as well as the inclusion of new energy sources into the ecosystem, (ii) control of invasions of alien species to new areas through the im-pact on the adaptive abilities of invaders and (iii) efficient accumulation of heavy metals resulting from the physiological properties of parasite tissues, and thus providing the ad-ditional environmental pollution index. The presented examples show that parasites play an important role as ecosystem engineers, affecting the dynamic balance of ecosystems. The present review aims to challenge the stereotype of parasitism as an unambiguously negative interaction and show evidence of the significant impact of parasites on healthy functioning communities and environmental safety.
De muro de paz a muro de la vergüenza. Prácticas artísticas populares feministas en México
Authors: Marín Vázquez Yaredh
Published: August 2021

Este artículo de reflexión es un ejercicio exploratorio sobre las múltiples relaciones que construyen y transforman los sentidos de un objeto. Desde una perspectiva antropológica, analizó los efectos y respuestas que detonó la instalación del llamado “muro de paz”—un cerco metálico alrededor de la sede del poder ejecutivo mexicano— como medida de “seguridad” ante las protestas feministas previstas para el 8 de marzo del 2021. En esta indagación me centro en los discursos y las acciones en disputa que dislocan y reubican estas vallas metálicas. Propongo comprender las intervenciones estéticas y discursivas del muro como prácticas artísticas populares feministas, acciones que transforman el objeto en memorial y lo renombran como “muro de la vergüenza”. Estas acciones desafían la narrativa histórica oficial en la que el movimiento feminista es identificado como “amenaza” y resitúan la problemática social que convoca las protestas. Argumento que el muro puede ser comprendido como una obra artística que convoca a un ejercicio de memoria en el que se hacen presentes las ausencias de las mujeres asesinadas y la ausencia de procesos de justicia. Las intervenciones sobre el muro me permiten reflexionar sobre la triada artista/obra/espectador una amalgama difícil de disociar. El objeto convertido en obra puede entenderse como una provocación que invita a seguir pensando en cómo se manifiesta el poder y cómo lo cuestionamos.

Vascular anomalies comprise a wide and heterogeneous group of lesions that may be found in all parts of the body, with most of the cases of vascular malformations involving the head and neck region. Ultrasound (US) is the reliable first-line imaging technique to assess flow parameters. However, in some cases, US fails to depict the real extent of the lesions. On the other hand, magnetic resonance imaging (MRI) allows the evaluation of the full extension and anatomic relationship of the vascular anomalies with the neighboring structures and provides hemodynamic characterization using dynamic contrast enhanced MRI (DCE-MRI), avoiding unnecessary invasive catheter-based procedures. DCE-MRI angiography can make a distinction between low and high flow vascular anomalies and it is useful for selecting adequate therapy and appreciating prognosis. The aim of this paper is to review the role of DCE -MRI in the evaluation of flow characteristics and lesion extent in vascular anomalies of the head and neck region.
