Práticas de apoio e inclusão escolar: do direito e justiça social para o capacitismo
Authors: Fröhlich Raquel
Published: December 2022

Este artigo problematiza as práticas de apoio à inclusão escolar e sua “reconfiguração” na esteira dos ataques antidemocráticos à educação pública. O avanço de movimentos neoconservadores coloca em risco conquistas históricas da inclusão escolar de pessoas com deficiência, questionando as práticas de apoio para a garantia de acesso, permanência, desenvolvimento e aprendizagem na educação. Com base nos Estudos Foucaultianos em Educação, utilizou-se a ferramenta teórico-metodológica do discurso para as análises dos materiais de pesquisa: políticas educacionais a partir da década de 1990 que versam sobre a inclusão escolar de pessoas com deficiência e artigos de revistas pedagógicas de décadas anteriores. As análises realizadas apontam um movimento que desloca as práticas de apoio do campo do “direito e da justiça social” para o campo do “capacitismo”. A efetivação de movimentos antidemocráticos fragiliza os processos de inclusão escolar, evidenciando um retrocesso no acesso à educação.
La educación de los sordos y la inclusión
Authors: Crespi Leonardo Peluso
Published: December 2022

En este trabajo analizo los tres paradigmas de educación de los sordos que actualmente existen en Uruguay en la órbita de la educación pública: la educación bilingüe, la educación bilingüe inclusiva y la educación inclusiva. A partir de la descripción de estos tres modelos, muestro la forma en que cada uno de ellos implica una visión diferente acerca del estudiantado sordo (de su lengua y de su cultura), así como también de las relaciones con la discapacidad y con la ideología de la normalidad. Finalmente presento el modelo de educación plurilingüe, pluritecnológico e intercultural, que puede ser una propuesta alternativa de educación de los sordos, en la medida en que supondría dar un paso más allá del bilingüismo. Los datos empíricos y la reflexión de este trabajo provienen de dos fuentes: una investigación educativa con financiación de la Administración Nacional de Enseñanza Pública (ANEP), ya realizada; y una investigación etnográfica y decolonial con financiación de la Comisión Sectorial de Investigación Científica (CSIC) de la Universidad de la República (CSIC, I +D, 2020), en curso.
Profissionais de apoio à inclusão e currículo de formação de professores/as
Authors: Caldeira Maria Carolina da Silva , Paraíso Marlucy Alves
Published: December 2022

Este artigo analisa o currículo do Programa Imersão Docente – Educação Especial, projeto de formação docente inicial desenvolvido em um Colégio de Aplicação, que proporciona o contato de graduandos/as com turmas que têm estudantes público-alvo da Educação Especial (PAEE) incluídos. Esses/as graduandos/as realizam atividades que se aproximam das desenvolvidas por aqueles/as que a legislação nomeia como Profissionais de Apoio à Inclusão. Com base em uma perspectiva pós-crítica, o objetivo deste estudo foi compreender as práticas demandadas aos/às graduandos/as quando assumiam essa posição de sujeito, partindo de seus relatos e percepções sobre o Programa. Utilizando entrevistas narrativas como metodologia, o argumento desenvolvido é o de que essa posição de sujeito tem como marcas as práticas de cuidado com o outro e a construção de estratégias de mediação entre o conhecimento escolar e os/as educandos PAEE. O processo de produção dessa posição de sujeito não se dá, todavia, sem conflitos que se manifestam pelo cansaço e pela responsabilização que muitos/as graduandos/as sentem.
Fundamentalismo e deficiência: a obstinação moderna pela igualdade
Authors: Lopes Maura Corcini , Veiga-Neto Alfredo José da
Published: December 2022

A igualdade é um ideal perseguido pela Modernidade; porém quanto mais a defendemos, parece que mais nos afastamos dela. Aqui, assume-se o pressuposto de que tal afastamento conecta-se com uma crescente adesão a variados “tipos” de fundamentalismos. Para compreender as conexões entre o ideal da igualdade e os fundamentalismos contemporâneos, aborda-se a relação entre os discursos pela igualdade e a deficiência, com foco nos mecanismos de positivação das desigualdades, circulando nas escolas de educação básica. Entende-se por positivação das desigualdades as práticas que marcam a presença da pessoa com deficiência e somam (de)méritos àqueles que com ela convive. As estatísticas das matrículas — da inclusão de pessoas com deficiência nas escolas de Educação Básica — e as narrativas docentes sobre práticas pedagógicas permitem concluir que discursos fundamentalistas sustentam a positivação das desigualdades e estigmatizam as pessoas com deficiência.
Evaluation of Khaya gum (Khaya senegalensis) as a polymer in the formulation of floating in situ gels of metoprolol succinate
Authors: Okunlola Adenike , Durodola Iyanu Abisoye
Published: December 2022

Metoprolol succinate, a β-selectiveadrenergic blocker, has a short half-life, low bioavailability, and high dosingfrequency. In-situ gel drug delivery is a good approach to achieve sustained release for once-daily administration thatwill prolong drugretention time at the stomach and increase absorption. Thus,the aim of the study is to formulate floatingin-situ gel formulations of metoprolol succinate using Khaya gum (Khayasenegalensis, family Meliaceae) as a polymer. Khaya gum wascharacterized and used in formulating in situ gels of metoprololsuccinate in comparison with Hydroxyl Propyl Methyl Cellulose (HPMC K15M) andXanthan gum. The in-situ gel formulations were characterized forappearance, swelling, in- vitro buoyancy and in-vitro drugrelease. FTIR revealed major peaks characteristic of the gum. Khaya gum showedhigh swelling and good flow properties. In-situ gel formulations of metoprolol succinatecontaining Khaya were light brown with near neutral pH, higher swelling and a total floating time >24 h,comparable to those containing HPMC and Xanthan gums. Dissolution time t80was 60.50 to >240 min with ranking Khaya <HPMC <Xanthan. Khaya gum providesa cheaper, suitable polymer for formulating floating in-situ gels with prolonged buoyancy and drug release.
Determinants of foreign direct investment in Central and Eastern Europe: Panel data analysis results
Authors: Zarić Snježana
Published: December 2022

The diffusion of technology and the knowledge spillover that accompanies foreign direct investment have made all countries, especially those in transition, interested in this type of capital inflow. Accordingly, in this paper, we have applied econometric panel models to identify determinants of foreign direct investment in Central and Eastern European countries. Our results indicate that differences in foreign direct investment flow in the analysed countries can, to a large extent, be explained by traditional factors such as the availability of skilled labour force, labour costs, infrastructure quality, and market size. In addition, the quality of institutions, primarily democratic government, an independent judiciary, and the absence of corruption, also significantly influence foreign companies' decisions about where to invest in countries in the region.

Published: December 2022

The history of the development of the deposit insurance system is quite long. There are a large number of different systems operating in the world that have changed over time, adapting to the circumstances in the environment. In any case, deposit insurance has become a central component of the financial safety net in most countries. The subject of this paper is an analysis of the development of the deposit insurance system throughout history, a comparative analysis of the organisation, functions and mandate of deposit insurers, with an emphasis on the importance of the deposit insurance system for preserving the country's financial stability. In addition, this paper aims to point out the importance of lessons derived from financial crises, which, above all, emphasised the need for financial system reforms and the creation of effective protection systems.

Authors: Njegomir Vladimir
Published: December 2022

Due to the COVID-19 pandemic, the world has changed completely in less than two years' time. The pandemic has threatened human lives, society, and global economy. As the largest pandemic of modern times, second only to the Spanish flu, it has had a significant negative impact on the economy, especially the service sector. The goal of this paper is to analyse the impact of COVID-19 on the economy. The analysis includes short-term economic effects in the first months of the outbreak, cost-and sector-specific impact, and economic expectations. The overall conclusion is that the pandemic has had severe negative impacts on the global economy, causing a significant GDP loss, increased unemployment, and the greatest decline in retail trade, compared to other recessions in the past 40 years. However, the pandemic has also accelerated the development of the digital economy.

Russia's neo-imperialist ambitions: Analysis of the foreign policy towards Georgia
Authors: Rajić Nikola
Published: December 2022

The Caucasus, dubbed "the Eurasian Balkans" by Zbigniew Brzezinski, or "the near abroad" (bližnee zarubež'e) by the Russians, is both a region of strategic interest for Russia, and a space where the Russian foreign policymaking was clearly manifested, Russia's main goal being to establish regional dominance and discourage the Western influence in the region. Using comparative and content analysis and relying on the theory of offensive structural realism, the paper will discuss the foreign policy of the Russian Federation towards Georgia in the years after the disintegration of the Soviet Union. Analysing the case studies of South Ossetia and Abkhazia, the paper seeks to show how Russia's neo-imperial foreign policy has been shaped, and how Russia's foreign policy has shifted in accordance with the part of the Caucasus involved in the conflict and the degree of anti-Russian influence in it. The results show that Russia carefully created the conditions and chose the moment to use the conflict, i.e., the secession on the Georgian soil, to position itself as a regional hegemon.
Tuberculosis: Old and new disease
Authors: Škodrić-Trifunović Vesna
Published: December 2022

M. tuberculosis is a part of the M. tuberculosis complex and is the causative agent of the infectious disease tuberculosis (TB) in humans. Lungs are the most frequently affected organ at about 90% of all the cases, and extrapulmonary localizations are less often and can affect any organ and tissue. Conventional diagnosis of tuberculosis includes: microscopy of ZiehlNeelsen-stained samples, cultivation of mycobacteria on solid Lowenstein medium, first-line antituberculosis (ATL) sensitivity test for M. tuberculosis. It is often a long long-lasting that lasts two to three months. In the last decades, methods for faster diagnosis of tuberculosis are of great importance and have found a place in practical work in equipped laboratories, and the results are obtained quickly, in a day or two. At the National Reference Laboratory, the Xpert MTB/RIF and GenoType MTBDRplus assays (Hain, Lifescience) are used for this purpose. Standard first-line therapy for the treatment of TB sensitive to antituberculosis drugs lasts 6 months and consists of four drugs: isoniazid, rifampicin, ethambutol and pyrazinamide. In the era of biological therapy, which significantly contributed to the successful treatment of many diseases and the extension of the lifespan, tuberculosis is still actual, due to the immunosuppressive effect of biological therapy, which affects the reactivation of latent infection and the development of active disease. A significantly high risk of TB occurs at the beginning of the administration of biological therapy, especially the first 6 to 12 months, and it is necessary to monitor the clinical course for 3-4 months. Compared to the general population, patients on anti-TNF therapy are 4 to 8 times more likely to develop active TB than those who are not receiving biological therapy. In most countries, screening and treatment of latent tuberculosis (LTBI) has been introduced before starting biological therapy, primarily with drugs from the TNF-alpha antagonists group, with the aim of reducing the incidence of active TB in these patients.
Swallowing disorders
Authors: Sotirović Jelena
Published: December 2022

Dysphagia represents the impairment of swallowing liquids and/or solid food and may occur due to an impairment of any part of the swallowing mechanism. Swallowing disorder has significant morbidity and mortality due to the possibility of malnutrition, loss of muscle mass, dehydration, aspiration, and aspirational pneumonia. Furthermore, it may significantly affect the quality of life and treatment of comorbidities. The purpose of this scoping review was to provide an overview of current guidelines and published literature (PubMed) to identify patients at risk for dysphagia eligible for further examinations, and treatment. Swallowing is a partly voluntary, and partly involuntary action. It can be divided into the oral, pharyngeal, and esophageal phases. Although swallowing disorders can occur in all age groups, they occur most often in the elderly, neurological patients, and patients with head and neck cancer. The diagnostic protocol for dysphagia includes a detailed history, physical examination of all structures involved in the act of swallowing, radiologic examinations (barium swallow test, videofluoroscopic swallow study, CT/MRI), endoscopic procedures (rigid or fiberoptic) and specific questionnaires to evaluate dietary intake, nutritional status and dysphagia-related quality of life. Therapeutic modalities include medications, correction of metabolic and nutritional deficits, bolus consistency modification, postural adjustments and swallow manoeuvers, specific exercise treatment, and surgery. Recently, an increasing number of studies have been published on sensory stimulation, which involves applying techniques like thermal and chemical stimulation, as well as neurostimulation in patients with dysphagia. Identifying persons at risk and treatment of dysphagia may prevent potentially fatal complications, reduce hospital length of stay and improve tolerance to the treatment of comorbidities.
Isotretinoin: 40 years of experience
Authors: Škiljević Dušan
Published: December 2022

Isotretinoin is a derivative of vitamin A (13-cis retinoic acid) and represents the first generation of retinoids. It affects all the key factors in the pathogenesis of acne and all current guidelines agree that it is still the most effective therapeutic option in the treatment of acne. In addition to conventional treatment, the modern concept of treatment allows various other protocols, so proper selection of patients and adjustment of isotretinoin treatment modality to the type and severity of acne is necessary to obtain optimal results. Although it was introduced into dermatological practice 40 years ago, this drug is still accompanied by certain controversies and doubts among doctors and patients. The main source of doubt is potential side effects such as teratogenicity, depression, suicide, and inflammatory bowel diseases. Decades of experience have shown that side effects (apart from teratogenicity) are mostly mild, reversible and rare. This paper presents modern approach regarding dosage, monitoring of patients during the treatment, as well as the identification and management of side effects.
Selenium: Role in preserving and improving health and preventing disease
Authors: Belojević Goran
Published: December 2022

Introduction: Selenium is a trace element whose importance for the functioning of the organism in health and disease is very intensively studied in modern research. This scientific evidence is constantly being supplemented, which requires monitoring and evaluation. Aim: The aim of this review paper is to systematize the results of relevant scientific research on the role of selenium in health preservation and promotion and the prevention of disease. Method: Available literature in English from the PubMed database was searched using the keywords "selenium"; "health"; "disease"; "toxicity"; "food"; "deficiency"; "cancer" and "diabetes mellitus". Results: Selenium is a microelement that manifests a powerful antioxidant effect within the enzyme phospholipid hydroperoxide glutathione peroxidase, while as a part of the enzyme deiodinase plays a role in the transformation of thyroxine into triiodothyronine. Brazilian nut is a food with an extremely high concentration of selenium, followed by tuna and oysters. Selenium deficiency in the body manifests as cardiomyopathy (Keshan disease) or osteoarthritis (Kashin-Beck's disease). Selenium poisoning is characterized by gastrointestinal and neurological symptoms, changes in the skin, on nails and garlic breath. Although a negative correlation has been observed between selenium concentration and the risk of carcinoma (breast, prostate, cervical, liver, gastric, thyroid, colorectal and bladder), studies have not shown so far a significant effect of selenium nutritional intake or supplementation in the prevention of cancer. Selenium concentrations are significantly lower in hepatitis, cirrhosis of the liver, obesity, autoimmune diseases (Hashimoto's disease, psoriasis, rheumatoid arthritis, ulcerous colitis, Crohn's disease), AIDS, and COVID-19, compared to healthy people. On the other hand, excessive selenium intake can increase the risk of diabetes mellitus type 2. Conclusion: Selenium has a significant physiological role in preserving health, primarily as an antioxidant and in the functioning of the thyroid gland, while selenium deficiency can be manifested by cardiomyopathy and osteoarthritis. Low concentrations of selenium in the body may increase the risk of several diseases: cancer, autoimmune diseases, AIDS and COVID-19. On the other hand, excessively high doses of selenium may increase the risk of diabetes mellitus or even poisoning - selenosis.
Direct oral anticoagulants in prevention and treatment of cancer-associated thrombosis
Authors: Antić Darko , Šarac Sofija , Otašević Vladimir
Published: December 2022

Patients with malignancy have higher risk of developing cancer-associated thrombosis (CAT), with predominance of venous thromboembolism (VTE). CAT in these patients leads to the delay of specific cancer treatment, worse treatment outcomes and also increased mortality rates. This article is evaluating the role of direct oral anticoagulants (DOAC) in the prophylaxis and treatment of VTE in patients with CAT. The review shed the light on the newest recommendations and guidelines, according to the newest treatment guidelines, but it also discusses the potential risks of DOAC therapy in patients with CAT. Compared to the previous recommendations, in the latest clinical guidelines for the prevention and treatment of CAT, DOAC are becoming more important. However, considering that cancer patients represent a highly specific group of patients, diversification and expansion of CAT anticoagulant therapy provides personalized approach to each patient achieving more efficient and safer profile of anticoagulant therapy.
On the global uniform stability analysis of non-autonomous dynamical systems: A survey
Authors: Hadj Taieb , Hammami M.A. , Hammi M.
Published: December 2022

In this survey, we introduce the notion of stability of time varying nonlinear systems. In particular we investigate the notion of global practical exponential stability for non-autonomous systems. The proposed approach for stability analysis is based on the determination of the bounds of perturbations that characterize the asymptotic convergence of the solutions to a closed ball centered at the origin.
Effects of the ARA transform method for time fractional problems
Authors: Çetınkaya Süleyman , Demir Ali
Published: December 2022

The aim of this study is to establish the solutions of time fractional mathematical problems with the aid of new integral transforms called the ARA transform. The fractional derivative is taken in the sense of Liouville-Caputo derivative. The fractional partial differential equations are reduced into ordinary differential equations. Later solving this fractional equation and applying inverse the ARA transform, the solution is acquired. The implementation of this transform for fractional differential equations is very similar to the implementation of the Laplace transform. However, the ARA transform allows us to take the integral transform of some functions for which we can not take the Laplace transform. The illustrated examples justify that the implementation and efficiency of this method are better than any other integral transforms to tackle time fractional differential equations (TFDEs).
Origen and liturgical symbolism: The teaching of the great Alexandrian theologian on church art
Authors: Stojanović Marina
Published: December 2022

The present paper aims to examine the relation between Liturgy as a service which is imbued with symbolism (and all kinds of art) and one typically spiritual view of communion with God. How could we reconcile Christian spirituality and liturgical symbolism? What is the view of Origen about liturgical symbolism? There are some opinions in academic research connecting Origen with iconoclastic beliefs in the Church. According to these opinions, Origen's concept of absolutely incorporeal God and the irreconcilable relation between spiritual and physical substances had influence on the repudiation of icons in Church in later times. In general, Origen's concept of God, human being and salvation formed one specific context for the theological understanding of human salvation and communion with God. With regard to this presumption, we will try to analyze it through the following steps. At first, we try to define the concept of body and material reality in Origen's ontology, as well as to contrast it to soul and spirit, which are largely emphasized in all his exegetical and other reflections. The second step is to try to reconstruct insights of Origen about symbols and icons in Liturgy. There is no complete exposition on this topic in his writings, but implicitly there is a possibility to investigate his teaching about icon and symbols. Here we take into consideration the idea of Christ as the icon of the invisible Father. Further, Origen mentions the concept of icon when he speaks about the difference between corporeal and spiritual man.
Liturgy of the Word and Tritekte
Authors: Marković Milan
Published: December 2022

The division of the Liturgy into two parts, the Liturgy of the Word and the Liturgy of the Eucharist, is well known and generally recognized. This division did not occur by chance and without reason. The reason for this division is easily noticeable when observing the order of the modern Liturgy. The fact is that the core of the first part of the Liturgy, the Liturgy of the Word, is the reading and interpretation of the Scriptures. On the other hand, the Liturgy of the Eucharist is based on the offering of the Mystery over the Mysteries. However, it is not the only reason for such a division of the structures of the Liturgy. Also, reason for this division is the history of the origin of these two parts of the Liturgy. The Liturgy of the Eucharist was in the early history defined as the Eucharist. The liturgy of the Word enters the Eucharist much later. The main assumption is that it derives its origin from the asmatic rite of the Tritecte. The same origin of the Liturgy of the Word and Tritekte is obvious. This conclusion is reached by simple observation of these two rites. In this paper, we will try to point out some different assumptions and conclusions. Trithekte is first mentioned in 8th century writings, as an integral service. On the other hand, the Liturgy of the Word is mentioned in the 5th century. This is the reason why cannot be valid attitude that the tritekte is origin of the Liturgy of the Word. We must look for the answer further in the history of the origin and development of Christian worship. We will look for the answer in the synaxis worship that originated in the early church.
The Diocese of Moravska: The later Diocese of Braničevo and the newly-found seal of Nikola, The Bishop of Moravska, from Svrljig
Authors: Andrejić Živojin
Published: December 2022

The bilingual inscription on the reverse of the seal of Nikola, the bishop of Moravska, recently found in a medieval suburb of Svrljig, was read and its content and representation of Saint Nicholas on the obverse were analysed in the paper. This resulted in new and important facts about the Serbian Principality of Morava and its diocese which was renamed in 1020. The Byzantine conquest led to addressing the "tema" of Morava, renaming of the diocese and transferring the throne from the town of Morava to the town of Braničevo. Consequently, it was concluded in the paper that this seal had been on Bishop Nikola's letter sent to a fellow monk from Svrljig in the second half of the 10th century or at the beginning of the 11th century.
Primacy of Church in the light of the appearance of Oicoymenicόs in the title of the Patriarch of Constantinople: Protests of Pope Gregory I Dialogos to Patriarch John IV Faster
Authors: Tubin Slaviša
Published: December 2022

The sixth century was a time of still-existing imperial unity and complete unity of Universal Church. Pope Gregory the Great was worried that this unity could be broken by adoption of title oicoymenicόs in the Constantinople by Patriarch John IV Faster. In the West this title is translated with the term of universalis and in language differences it is understood that Constantinople patriarch wants to be the head of the Whole (Universal) Church. Pope Gregory begins to strongly protest and to demand that the patriarch reject the title oicoymenicόs as a profane addition. Theological problematization of the title was created in dispute between Old and New Rome. Pope considered that addition of title brings canonical problem and danger of schism. But he saw greatest danger in the Ecclesiological and Christological consequences. They implied that oicoymenicόs makes patriarch as the Head of Universal Church instead of Christ and makes dilaceration Corpus of the Lord. Through the mediation of the Eastern Patriarchs and clarification of the etymologically key pope preserves Ecclesial Unity.
The Ravenna document and the future of Orthodox-Catholic dialogue

Soil horizon-dependent heavy metals, and micro-and macro-elements distributions: A case study of Futoški park (Novi Sad, Serbia)
Authors: Kostić Saša , Kebert Marko , Todorović Helena , Pekeč Saša , Zorić Martina , Stojanović Dejan , Orlović Saša
Published: December 2022

We analyzed macro-(Ca, Mg, and K) and microelements (Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in soil from three depths that correspond to different soil horizons (0-60, 61-75, and 76-160 cm) from three sites in Futoški park (Novi Sad, Serbia), which was measured by using the atomic absorption spectrophotometry (AAS). In this study, we tested the influence of spatial arrangement and soil depth on the variation of micro-and macro-element contents using (i) two-way ANOVA with the site, soil depth, and their interactions as dependent variables, (ii) Tukey post-hoc test (for p<0.05), and (iii) principal component analyzes (PCA). Except for Cd, all measured samples are below of the limit value prescribed by the Serbian national legislation. Likewise, Cr is very close to the maximum allowed amount. According to the results of two-way ANOVA statistics, sites, soil depth, as well as their interaction statistically significantly influenced the content of all examined macro-and micro-elements in the analyzed soils. Following the PCA (which covers ˃90% of samples), surface horizons deviate from all three sites, and stronger deviations between the first and the other two horizons which are very similar were noted. In detail, on the surface horizon higher concentrations of K, Cu, Cr, Fe, Mn, Ni, and Zn were detected, opposite to Ca, Cd, and Mg.
A Vulnerability Criterion of Dynamic Instability for Ship Course-Keeping in Following Waves
Authors: Margari Vicky , Spyrou Kostas J.
Published: December 2022

_

A practical criterion which can be used for assessing the course-keeping capability of a ship in following waves, is proposed and evaluated. Presently, it accounts for regular waves and it accrued from an analytical estimation of the course instability region’s boundary by applying the method of harmonic balance. The calculation is performed with regard to the third-order yaw equation, derived from a classic sway-yaw-rudder model of ship maneuvering motions, with time-dependent coefficients at two places, which is like a Mathieu-type equation extended to third order. The proposed analytical criterion was evaluated thoroughly against simulations with regard to this sway-yaw model and it was found to be adequately accurate. A supplementary quasi-static yaw stability criterion (fitting to ship operation with frequency of encounter, with respect to the waves, close to zero) was also considered in order to determine which one yields more stringent requirements, for various operating conditions. The proposed criterion could be an extra vulnerability check for broaching-to, in the context of the Second Generation Intact Stability Criteria.

Introduction

The difficulties of steering of ships in following seas have received the attention of the research community since more than 70 years ago (Davidson 1948). A relevant direction of research refers to the avoidance of the broaching-to instability and, in particular, to the development of practical criteria that could ensure sufficient course-keeping capability for a ship encountering steep following waves. Some classic works on this topic, such as those of DuCane and Goodrich (1962), Wahab and Swaan (1964), and Motora et al. (1981), were focused on the quasi-static condition of a ship on the wave which could be practically realized if the ship was advancing with speed equal to the wave celerity (zero frequency of encounter). As implied, these works were essentially focused on the avoidance of a type of broaching-to instability that is preceded by the realization of surf-riding, a phenomenon where the ship is forced to move with the wave, usually riding a downslope.
A Simplified Analytical Solution for the Computation of Machine Path in Filament Winding of Cylindrical Angle-Ply and Double-Double Structures
Authors: Andrianov A. , Militão A.P.F.
Published: December 2022

This paper presents a simplified computation approach for the machine path (or winding trajectory) of grid structures and tubes with a circular cross-section and angle-ply or double-double layup. The solution for the machine path is given through controllable degrees of freedom of a low-cost two-axis filament winding machine (FWM): mandrel rotation and translation of the delivery eye along the axis of the mandrel. The efficiency of the analytical solution for the machine path of the FWM was ascertained by automated laying the cotton thread over the geodesic and non-geodesic groove imprinted on the surface of a cylindrical polylactide mandrel. These results validated the possibility of manufacturing cylindrical composite structures with an angle-ply layup or double-double stacking sequence, without the need for expensive software, making the winding technology accessible to society and promoting university extension.
Does the ‘more appropriate’ authority need to be independent? Rule of law implications for case referrals with respect of concentrations
Authors:   Faculty of Law and Administration, Adam Mickiewicz University,, Malaga Miłosz
Published: December 2022

In the recent Sped-Pro judgment, the General Court ruled that in order to guarantee effective judicial protection of the complainant, the Commission is obliged to examine the given national competition authority’s independence, and overall rule of law concerns, when it rejects complaints regarding Article 102 TFEU and concludes that such an authority is ‘best placed’ to hear the case. This contribution aims to discuss whether such obligation applies to case referrals from the Commission to Member States with respect of concentrations. On one hand, these are the same national competition authorities and the same standards should apply. On the other – the case referral system differs from the characteristics of the Articles 101–102 TFEU framework. Thus, this paper contains a discussion on the General Court’s judgment in Sped-Pro, the legal framework and practice regarding merger referrals, and, finally, the consequences of the judgment for the future approach of the Commission in the discussed matter.
How to care for fetuses with prenatally diagnosed severe abnormalities

Published: December 2022

Ultrasound in pregnancy has become standard of care, resulting in an increased number of antenatally diagnosed fetal anomalies. It isimportant to have a consistent approach to the management of these abnormalities. This may include offering termination of pregnancy,standard care or non-aggressive/palliative care. A categorisation of anomalies and management options is proposed to assist with thesedecisions, underpinned by an ethical framework.
A proposed fetal risk scoring system for gestational diabetes to assist in optimising timing of delivery
Authors: Bhorat I , Reddy R
Published: December 2022

Background. The pathophysiology of gestational diabetes, which is related to abnormal gluocose tolerance and hyperinsulinaemia, renders standard fetal monitoring models ineffective, insufficient and inappropriate, as these models revolve around detecting and prognosticating on placenta-mediated disease rather than increased metabolic rates due to hyperinsulinaemia, functional hypoxia and ischaemic trophoblastic thresholds. To improve perinatal morbidity and mortality in gestational diabetes, there is therefore a need to introduce new prognostic parameters and scoring systems.

Objectives. A proposed risk scoring system has been developed, based on our previous studies, to risk-categorise patients with gestational diabetes in terms of fetal outcome in view of the fact that the pathophysiology of gestational diabetes is not recognised by standard monitoring models, which revolve around placental insufficiency rather than metabolic anomalies.Methods. Patients with diabetes from four case-control studies were combined to form a total sample of 159 cases for validation of the risk scoring system. Univariate logistic regression analysis was used to assess the effect of individual risk factors with proposed cut-offs on adverse pregnancy outcome. The diagnostic accuracy of the total summative score was assessed by computing the area under the receiver operating characteristic (ROC) curve.

Results. Four potential parameters were identified to risk-categorise fetuses in a pregnancy complicated by gestational diabetes, i.e. the myocardial performance index (MPI), the E/A ratio (early diastolic filling/late diastolic filling, a marker of diastolic dysfunction), increasing fetal weight (macrosomia), and an increased amniotic fluid index. The total score, obtained by summation of the composite scores for these parameters, ranged from 0 to 11. The total score performed as an excellent predictor of adverse outcome, evidenced by an ROC area under the curve of 0.94. A cut-point of 6 on the score confers a sensitivity of 84.2% and specificity of 90.2% for predicting adverse outcome.

Conclusion. To our knowledge, this is the first gestational diabetes scoring system proposed to predict an adverse outcome.
Toponymic Research and Scientific Collaborations: in Search of a Common Language
Authors: Gordova Yuliana
Published: December 2022

The subject of the study is the interdisciplinary terminology of toponymy. The purpose of the work is to define and describe new terms that can be used in toponymic and multi-scientific research on toponymy conducted by linguists, geographers and historians. The glossary of terms is formed by sampling them from the latest toponymic works and analyzing their semantics in the original scientific field of use (geography, archeology), and then in toponymy. Particular attention is paid to terms that have a commonly used scientific vocabulary as a reference word (river, degradation, stairs), since it is these terms that are understandable to representatives of different scientific fields, and therefore have the greatest potential for entering the current terminological base of toponymy. The result of the work is a description of the terms of geography, archeology, toponymy itself, linguistics of other directions – a total of 14 terms; situations in which they can be used, and toponyms illustrating a particular situation. The acquired knowledge can be applied in interdisciplinary toponymic research and should contribute to the development of a common language of toponymy, understandable to both linguists and representatives of other sciences studying geographical names, which is the novelty of the findings. It is established that some of the terms toponymy borrows from other scientific directions without changes, with the original semantics, actively including in the scientific description and analysis (small, medium, large rivers). The part transforms by adding new meanings or adapting to the demands of toponymy (natural landscape (in geography) – toponymic landscape, chronostratigraphy (in archaeology) – toponymic stratigraphy). The article discusses new terms of other sciences that seem convenient for analyzing specific toponymic processes: degradation of water bodies, littonym, lot (terms of hydrology and oceanology), as well as well-known but rarely used terms of toponymy itself.

Published: December 2022

The subject of the study are the results obtained in the course of electroacoustic analysis of a single text. This fragment is part of an interview recorded by an Indian student studying French in the Republic of India. The auditor participating in the recording of the phonogram of the fragment is a resident of South India, living in the state of Tamil Nadu. The task of the experiment carried out by the authors is to study the methods of intonation selection using the main prosodic characteristics of the semantics of texts of various subjects. The object of this study is the analysis of indicators of the frequency of the main tone, intensity, duration, and pause. The article contains a table consisting of the results of processing acoustic data obtained using the PRAAT software, which provides the ability to process and analyze sounding speech. The authors consider in detail the procedure of the experiment, which consists in transcribing the text, highlighting lexico-semantic lines opposed to each other, the process of rationing according to the formulas given in the article, as well as analyzing the results. The main conclusion of the study is the calculation of deviations from the average values of the main acoustic parameters that characterize words that express the semantic lines of the text and are combined into two opposed lexico-semantic complexes.

Effect of synthetic jet on circular cylinder radiated noise in laminar flow state

This article focuses on the effect of active control via synthetic jets (SJs) on sound generated by a two-dimensional circular cylinder by using the acoustic analogy method. The cylinder is immersed in a uniform upstream flow, where the corresponding Reynolds number is 100 and the Mach number is 0.1. A pair of SJs is placed near the cylinder’s separation point issuing periodically varying forcing, with different combinations of forcing frequency and phase difference. The lattice Boltzmann method (LBM) is coupled with the multi-direct forcing immersed boundary method to solve the near-field flow dynamics. The mechanism of the sound generation lies in the fact that pressure pluses are induced by the periodic vortex shedding from the cylinder’s surface, i.e. dipoles. In the case with active flow control, extra monopoles are generated by the unsteady flow rate resulting from the SJs' periodic blow/suction. The interaction between monopoles and dipoles is confirmed to have a big influence on the acoustic field. The acoustic analogy method is used in various cases with a wide range of control parameters, because it has a considerably lower computational cost than the direct simulation method. Taking into account the effect of the monopole, the acoustic analogy method is developed for solving two-dimensional sound field by substituting the Green’s function. Results indicate that the primary lock-on and the secondary lock-on occur in the case of specified control parameters. The frequency of vortex shedding is related to the SJs’ frequency, deviating from the unforced frequency. Owing to the noise induced by flow, the frequency and phase difference of the SJs also have significant influence on sound field. The far-field noise is enlarged although the SJs reduce drag, due to the induced extra monopole, as well as the strengthened hydrodynamic fluctuation. Further increasing SJs’ frequency or reducing the phase difference will enlarge the far-field noise and make the directivity transformed from dipole to monopole, since the SJs’ self-noise is stronger. Moreover, it is found that the acoustic power increases approximately 4–18 dB compared with the unforced circular cylinder and the drag dipole is strengthened in all combinations of control parameters. This study deepens the understanding of the effect of SJs on sound field, and provides a reference for future studying the control strategies of suppressing noise generated from bluff bodies.
Forty new specimens of Ichthyornis provide unprecedented insight into the postcranial morphology of crownward stem group birds

Published: December 2022

Ichthyornis has long been recognized as a pivotally important fossil taxon for understanding the latest stages of the dinosaur–bird transition, but little significant new postcranial material has been brought to light since initial descriptions of partial skeletons in the 19th Century. Here, we present new information on the postcranial morphology of Ichthyornis from 40 previously undescribed specimens, providing the most complete morphological assessment of the postcranial skeleton of Ichthyornis to date. The new material includes four partially complete skeletons and numerous well-preserved isolated elements, enabling new anatomical observations such as muscle attachments previously undescribed for Mesozoic euornitheans. Among the elements that were previously unknown or poorly represented for Ichthyornis, the new specimens include an almost-complete axial series, a hypocleideum-bearing furcula, radial carpal bones, fibulae, a complete tarsometatarsus bearing a rudimentary hypotarsus, and one of the first-known nearly complete three-dimensional sterna from a Mesozoic avialan. Several pedal phalanges are preserved, revealing a remarkably enlarged pes presumably related to foot-propelled swimming. Although diagnosable as Ichthyornis, the new specimens exhibit a substantial degree of morphological variation, some of which may relate to ontogenetic changes. Phylogenetic analyses incorporating our new data and employing alternative morphological datasets recover Ichthyornis stemward of Hesperornithes and Iaceornis, in line with some recent hypotheses regarding the topology of the crownward-most portion of the avian stem group, and we establish phylogenetically-defined clade names for relevant avialan subclades to help facilitate consistent discourse in future work. The new information provided by these specimens improves our understanding of morphological evolution among the crownward-most non-neornithine avialans immediately preceding the origin of crown group birds.
