Problem of Vibration Damping in Mechanical Systems: System Analysis, Modeling, Control
Authors: Eliseev A. V. , Khomenko A. P.
Published: May 2022

System approaches are being developed in the problems of dynamics of transport and technological machines related to the provision of dynamic vibration damping modes and the identification of a number of specific effects characteristic of technical objects with working bodies representing solids. The methods of structural mathematical modeling are used, in which a mechanical oscillatory system, considered as a design scheme of a technical object, is compared with a structural scheme, equivalent in dynamic terms, of an automatic control system. It is shown that the modes of dynamic damping are realized through the fixation of fixed points called centers of rotation (or oscillations). A method is proposed for the analytical evaluation of the possibilities of forming dynamic states based on the use of generalized feedback transfer functions, coefficients of motion connectivity by coordinates, forms of dynamic interaction of system elements under the simultaneous action of two harmonic excitations. Within the framework of the interpretation under consideration, the key characteristic of a mechanical oscillatory system is the characteristic frequency equation and its transformations. The development of ideas about the form of dynamic interactions of elements of a mechanical oscillatory system is proposed. The concept of form generalizes ideas about the directions of change in time of the coordinate of a system element in relation to a change in an external force or kinematic excitation. The methodology for displaying a set of dynamic states and forms of dynamic interaction of elements of a mechanical oscillatory system based on oriented graphs is proposed.

Published: May 2022

The paper describes the developed automated device for the formation of electrocatalytic layers used in electrochemical systems, and the issues of development of the sputtering technology, which allows to obtain the best parameters of the formed active layers. The general scheme of the automated device includes a system of automatic positioning of the spraying head according to two coordinates, driven by stepper motors controlled by a personal computer, an ultrasonic mini-disperser, a spraying head, ultrasonic generators for the ultrasonic mini-disperser, and the ultrasonic spraying head. Stepper motors were controlled by microprocessor system based on 8-bit Atmel AT90S2313 single-chip microcontroller and standard buffer microcircuits. The key actuating element of the device and the process is the developed atomizing head with an integrated ultrasonic homogenizer that prevents sedimentation of the catalytic composition. The overall automation circuit designed and reproduced to control all electronic devices was described in detail. It differed by application of Attiny2313 microprocessor for the control, availability of communication with personal computer via RS-485 interface that allowed not only to switch the disperser on/off, but also to control its working frequency directly from the personal computer. It was envisaged both manual control of stepper motor controller via control buttons and control from external personal computer, which had the opportunity to control spraying program step by step. In this case all the sequence of steps is contained in the personal computer memory, it is transmitted to the stepper motor controller step-by-step as the program is being executed. Algorithms for moving the spraying head that provide the best drying of catalytic composition in the process of its application have been developed. The effectiveness of the developed automated device has been shown by comparing it with manual application by a specialist according to such criteria as the rate of application of electrocatalytic layers and their quality. The created device, algorithms of its operation, software and scientific and technological advance, in general, can be used for the formation of various coatings both in electrochemical technologies and in other fields.

Authors: AĞALDAY Bünyamin , GÜL Mehmet
Published: May 2022

Bu çalışma, okul müdürlerinin okula finansal kaynak sağlamada yaşadıkları sorunları ve bu sorunlara ilişkin çözüm önerilerini incelemektedir. Çalışma, nitel araştırma yönteminin olgubilim deseniyle gerçekleştirilmiştir. Araştırma, 2021-2022 eğitim-öğretim yılında yürütülmüştür. Araştırmanın çalışma grubu, Diyarbakır’da görevli on beş anaokulu, ilkokul ve ortaokul müdüründen oluşmaktadır. Okulların seçiminde ölçüt örnekleme yöntemi kullanılırken, okul müdürlerinin seçiminde ise maksimum çeşitlilik örnekleme yöntemi kullanılmıştır. Araştırmanın verileri, araştırmacılar tarafından oluşturulmuş yarı yapılandırılmış görüşme formu ile toplanmıştır. Veriler, betimsel analiz ve içerik analizi ile analiz edilmiştir. Araştırmanın sonucunda, bütün kademelerde finansman sorununun yaşandığı ancak bu sorunun, zorunlu eğitim kapsamında bulunmayan ve bu nedenle maddi kaynak ayrılmayan okul öncesi eğitim kurumlarında daha belirgin yaşandığı görülmüştür. Okul müdürlerinin, finansman kaynağı yaratmak için fazla zaman harcadıklarını ve bu nedenle diğer önemli görevlerini yeterince yapamadıkları sonucuna ulaşılmıştır. Okul müdürleri, finansman sorunlarının kaynağı olarak, okullara yeterince ödenek ayrılmaması ve okul aile birliklerinin sorumluluklarını yerine getirmemesini görmektedirler. Bununla birlikte, finansman sorunlarının, okul müdürlerinin motivasyonu düşürürken, öğretmenlerin de performansını olumsuz etkilediği sonucuna ulaşılmıştır. Okul müdürleri, finansman sorununun çözümünde, her şeyden önce, her okulun kendi bütçesinin olması gerektiğini belirtmişlerdir. Yanı sıra, okula yapılacak bağışlar konusunda, yerel yönetimlerin okulların finanse edilmesinde aktif bir rol alması gerektiğini önermişlerdir. Araştırmacılar tarafından politika yapıcılara yönelik, okul temelli bütçe hazırlanması ve okul işletmecilik yönetim sisteminin kurulması önerilmiştir.

EVOLUTION OF CIVIL LAW SCIENCE: DOGMA AND METAPHYSICS
Authors:   Taras Shevchenko National University of Kyiv, Bezklubyi I.
Published: May 2022

The article considers the influence of the doctrine of dogmatism on the development of Civil Law Science. Problems of reviving the metaphysical approach and metaphysical principles in civil doctrine are raised. Aspects of pragmatic improvement of modern civil legislation in Ukraine are touched upon. The appeal to the theoretical problems of methodology in civil law is caused by the desire to see in which direction modern Civil Law Science is developing, and to understand how dogma and metaphysics can affect modern civil law relations. Having a significant arsenal of modern methods of scientific knowledge of civil studies, scientists often overlook the metaphysical basis of social relations. With regard to jurisprudence, we emphasize the methodology, in its deep and broad sense, which helps not only in finding criteria for distinguishing areas of objective law and definition, subjective rights of participants in relevant social relations, but also in shaping our knowledge of holistic pictures of the phenomenon of law and its future. The question of the relationship between dogmatic and positivist theories in civil doctrine is revealed; it is about the interaction of metaphysical and empirical principles in the context of understanding the fact as a certain experience. It is noted that none of the legal sciences is as close to the concept of dogma as civil law. Using the historical method indicates the temporal change of legal institutions and their dogmatic analysis on the example of Roman law and its reception. The article notes that jurisprudence as a humanity in the current conditions of society remains relevant. With the use of a broad professional conceptual apparatus, it is able to create ideal opportunities to promote common ideas and hypotheses related to the development of legal order. Keywords: dogmatism, thing, possession, methodology, morality, positivism, legal institution, private law, fact.
THE PECULIARITIES OF DISCIPLINARY RESPONSIBILITY OF LAWYERS FOR VIOLATION OF THE RULES ON ADVOCATES ETHICS
Authors:   Taras Shevchenko National University of Kyiv, Kukhniuk D.
Published: May 2022

The purpose of this study is to reveal the peculiarities of disciplinary responsibility of lawyers for violation of the Rules on Advocates Ethics. This requires clarification of the grounds for bringing a lawyer to disciplinary responsibility, the improvement of the rules of disciplinary proceedings against a lawyer, and the differentiation of the types of sanctions that can be applied to a lawyer. The article uses such methods of research as: comparison and generalization – to disclose the changes made in the new edition of the Rules of lawyer ethics, analysis and synthesis, induction and deduction. The result of the study is the disclosure of peculiarities of bringing to disciplinary responsibility both Ukrainian and foreign lawyers. The new edition of the Rules on Advocates Ethics has been analysed in the context of a comparison with the previous edition and proposals have been made to improve the current provisions of the new edition of the Rules on Advocates Ethics regarding the criteria of evaluation of ethical aspects of advocate's conduct in disciplinary proceedings of qualification and disciplinary commissions of the Bar; the need to returnsome important provisions to the principle of independence and freedom of advocacy in carrying out their activities was outlined. It has been substantiated that it is inappropriate to establish a special procedure for bringing advocates to disciplinary responsibility in case they violate the Rules of Advocates Ethics. In the conclusions, it should be noted that the rules of Rules of Advocates Ethics should not duplicate the procedural rules of the Law and the Regulation on the procedure for acceptance and consideration of complaints about improper conduct of an advocate, which may entail his disciplinary responsibility. Keywords: rules of advocate's ethics, disciplinary responsibility of an advocate, grounds for disciplinary responsibility of an advocate, disciplinary penalties.
The barbarian’s periphery of Byzantine Empire (some arguments about the origin of Turk’s tribes)
Authors:   Taras Shevchenko National University of Kyiv, Zhdanovych Olesia
Published: May 2022

This article describes some of barbarians in the northern periphery of the Byzantine Empire. The barbaric periphery of Byzantium in the early Middle Ages was quite diverse. World historiography is rich in research on Western European barbarians. There are still many questions about the nomadic peoples that appeared at different times on the territory of the Dnieper, the Black Sea and the Danube, and their relations with the Byzantine Empire in the early Middle Ages. Oriental scholars research the northeastern nomads separately, while the medieval Byzantine scholars focus on problems related to the inner life of the Empire. The foreign policy focus is mainly directed at the closer barbarians who established themselves in the territory of the West. However, there are many questions about cooperation between the Turkic nomads and romans during the period of their active contacts. Official diplomatic missions between two civilized worlds, thanks to the sources that describe embassies, allow us to see not only relations between empires, but also some ways of life, social structure and political organization in nomad’s states. In the context of the analysis of active contacts between the romans and the nomads, we turn to the problem of the origin of «barbarians»and their contacts with the Byzantines. The ethnogenesis of some Turkic peoples and their migration from northeast to southwest still raises more questions in the world historiography than answers. Our attempt to understand this situation is based mainly on Roman-Byzantine written evidence. A deliberately chosen analysis of the subjective Byzantine view of the origin of Turkic nomads clarifies some confusing situations regarding the researching of intercivilizational processes in Europe during the last period of the Great Migration.
The gold coins counterfeiting in Ukraine in XIX – the beginning of XX centuries
Authors:   National museum of Ukrainian history, Boiko-Gagarin Andrii
Published: May 2022

The problem of the money counterfeiting in Russian Empire has long been out of sight of the scientists, in Ukraine doesn’t exist any single comprehensive work devoted to the study of this problem. In the period of the Russian Empire rule in Ukraine, the counterfeiting of gold coins acquires its own features and tendencies. This article introduces into the scientific circulation the materials of the state historical archives criminal cases, newspapers and museum collections related to the falsification of the gold coins in Ukraine. During the XVIII century the gold coins were little known to the public, that’s why the cases of falsification of them through the historical sources are unknown. Before the middle of the XIX century the counterfeiting of the foreign gold coins was widespread. The traditional crime was clipping of the gold and silver coins, which was also fixed in the studied period. In the late 18th and early 19th centuries, due to the small number of Russian gold coins in the circulation, the counterfeiters used foreign Holland ducats and Ottoman mahmudis as a model. Counterfeiting of the Russian gold coins has been known since the middle of the 19th century. False semi-imperials are known from Ukrainian finds, although analysis of the sources indicates their potential importation from the Baltic provinces, where they were probably manufactured. With the introduction of the gold standard in Russian Empire, the new coins are rapidly gaining a high popularity. Extensive use of the new gold coins leads to the falsification of almost the entire line of the denominations. Even the rarest gold coin of 7 rubles and 50 kopecks, minted only in 1897, was identified in Zhytomyr. Counterfeits of the gold coins also came to the Ukrainian provinces from the neighboring regions, as in 1911 the fact of importation of the counterfeit imperials was revealed from Nakhichevan. The First World War has radically changed the principles of the money circulation in Ukraine. The huge was expenses and the financial crisis led to a «coin hunger», the use of money substitutes and speculation with small coins. The gold coins were purposefully withdrawn from the population in exchange for paper banknotes. We suggest that the known today specimens of the counterfeit coins made for the loss of the money circulation could have been made during the financial crisis of the WWI.
M. Brechkevich (1870–1963) and his contribution to the study of the medieval history of Baltic Pomerania
Authors:   Taras Shevchenko National University of Kyiv, Rud Mykola
Published: May 2022

In the article based on archival sources and special historical literature, it is given the characteristics of main points of live, scientific and pedagogical work of famous Ukrainian historian, medievalist, the founder of the Department of Ancient and Medieval history in Taras Shevchenko National University of Kyiv Mytrofan Vasyliovych Brechkevych. The research is based on the historicism, scientific and author’s objectivity, general scientific (analysis, synthesis, generalization, comparation) and special historical (historic-typological and historic-systematic) methods. In the article the contribution of M. V. Brechkevych was analyzed. The author came to the conclusion, that during his professional live Brechkevych remained true to the principles developed at the beginning of his career. He was a historian-positivist, who as the rest of the scientist of this direction considered the historical source to be the main criterion of truth. The main object of Brechkevych’s scientific research was the history of the Pomeranian Slavs of the 12th – 14th centuries, to which he dedicated numbers of his works in the first half of the 20th century. In his first printed work «Sviatopolk – Prince of Pomerania» (Yuriiv, 1902) Brechkevych considered one of the important periods in the history of the East Pomeranian principality, its struggle with the Teutonic Order in the 1240s. The study comprehensively analyzes the question of the origin of princely power in Eastern Pomerania, the relationships of the Eastern Pomeranian principality with Poland. Brechkevych’s main work on the history of Pomerania was his master’s thesis «Introduction to the social history of the principality of Slavia, or Western Pomerania» (Yuriiv, 1911), in which he made an attempt to analyze on the basis of Pomeranian letters and chronicles the process of feudalization in the West Pomeranian lands during the 12th – 13th centuries and the role of German colonists in it. The work describes in details the princely land tenure, the formation of the first Pomeranian monasteries, which became active leaders of Germanization in this region.
Shevchenko’s Vision of Ukraine: Territorial Aspect
Authors:   Volodymyr-Volyn pedagogical professional college named after A. Yu. Krymskyi, Nahirnyi Mykola
Published: May 2022

The article examines on which territory the term «Ukraine» spread in the Taras Shevchenko’s vision. In the Middle Ages there was confusion in the use of the names «Little Russia», «Ukraine», «Rus’» to designate the historical and geographical lands of Ukrainian people. The term «Ukraine» during centuries evolved in the semantic and geographic aspects. T. Shevchenko in separate his poems distinguishes the concept «Ukraine» and its regions (for example, «Volyn’» is mentioned separately). However, the analysis of Shevchenko’s works, the geography of his travels and interests suggests that the poet included in the actual understanding of Ukraine the lands that, in different periods, were part of the notion of «Rus’», «Hetmanshchyna», «Cossack’s Ukraine», «Little Russia». Territorially Shevchenko’s Ukraine was imposed on all these lands. Geographical and spatial Shevchenko’s imagines about the land, which he called «Ukraine» in his work, we can check through his travels in the Ukrainian lands, his poetry and other activity, the ratio of historical or geographical concepts used by him or information about the regions which the poet was interested in. In accordance with these criteria, Shevchenko could include into his great homeland the territory of the Cossack state of B. Khmelnytsky and which correspond to the concept of «Rus», with the inclusion of lands of Slobozhanshchyna. Belonging to this Shevchenko Ukraine of Transcarpathia, Donbass and Crimea remains unconfirmed and needs further refinement and research.

Authors: P Chikkahonnaiah , KK Abdulla , J Varshini
Published: May 2022

Background: Coronavirus disease 2019 (COVID-19) has caused large number of deaths all over the world. Our study was conducted to investigate the factors affecting mortality in patients hospitalized with COVID-19 during second wave of pandemic in India. Material and methods: The data was collected retrospectively from the medical records of P. K. Trauma Care Centre, Mysuru where exclusively COVID-19 patients were admitted during second wave of COVID-19 pandemic in India. This study included total of 98 patients who expired due to COVID-19 during the period of March 2021 to October 2021. Demographic details, clinical presentation, treatment and laboratory data were extracted from medical records. We analysed the significance of the data using chi square test and other statistical tests. Results: A total of 948 cases were admitted during the said period and 98 patients expired. With statistical analysis following factors are found to be significantly associated with high mortality - age above 60 years, unvaccinated, low oxygen saturation at presentation to the hospital, high serum ferritin level, elevated neutrophil –lymphocyte ratio (NLR), elevated D-dimer level, presence of co-morbidities. Duration of symptoms with which the patients presents to the hospital is the least significant factor associated with the mortality. Conclusion: Elderly age group, lack of vaccination, low oxygen saturation at presentation to the hospital, presence of comorbidities like diabetes, hypertension and ischemic heart disease, elevated serum ferritin, D-dimer level and high NL ratio are associated significantly with high mortality in patients with COVID-19 infection. Vaccination, monitoring of oxygen saturation and proper management and control of comorbidities are the easily modifiable factors to reduce the mortality in COVID-19 patients.

Authors: R Priyashree , CM Shyamsundar , NS Kumar
Published: May 2022

Introduction: Acute kidney injury (AKI) is associated with significant mortality and prognosis depends on spectrum of etiologies and management. There are regional differences in etiology and outcomes of AKI. This study was undertaken to determine clinical characteristics, etiologies of AKI, modality of treatment and prognosis of AKI in our cohort of population. Methodology: This is a retrospective observational study conducted over a period of 6 months from a tertiary care hospital. All patients above 15 years admitted with AKI are included in the study. Clinical parameters, risk factors, cause of AKI (as per KDIGO criteria) and treatment received were studied. Patients with underlying chronic kidney disease (CKD), obstructive causes, drugs and toxin mediated AKI were excluded from the study. Results: A total of 50 patients with AKI were studied in this period. The mean age of patient was 41 years with slightly predominant male patients. The common etiologies of AKI included: infections (48%), snake bite (18%), hepatorenal syndrome (18%), cardiorenal causes (10%), and rhabdomyolysis in 6%. Oliguria was most common symptom at presentation (46%) followed by fever and breathlessness. Dialysis was required in 22 patients. Dialysis was equally effective in infective and non-infective causes of AKI. Mean duration of hospital stay was 7.8±2.5 days. Two patients died during study period due to multiorgan failure. Conclusion: Infections are common cause for AKI in this study. Renal replacement therapy is equally effective in both infective and non-infective causes of AKI with favourable prognosis.
Purple urine bag syndrome in catheter associated urinary tract infection: A case report
Authors: K Pannala , A Panda , SP Keshri
Published: May 2022

Purple urine bag syndrome (PUBS) occurs in catheterized patients with bacterial urinary infections that produce sulphatase/ phosphatase. The presence of indigo and indirubin pigments, which are tryptophan metabolites, causes the purple coloring. After antibiotic therapy, the purple colour reverts to normal. We present a case report of unusual phenomenon occurring in a 60-year-old woman with carcinoma cervix. She did not have fever, constipation or a history of medication administration. She presented with purple urine in her indwelling long term supra-pubic catheter bag and sought a consultation with an urologist because the urine in her urine bag had changed color to purple. Awareness about PUBS will prevent unnecessary investigation and over treatment.
Culo prieto, cabeza ausente
Authors: Menéndez Menéndez María Isabel
Published: May 2022

Los medios de comunicación de masas, a mediados del siglo XX, abrazaron lo que podría denominarse “industrialización de la pornografía”. Con la aparición de revistas como Playboy, el imaginario pornográfico abandonaba su carácter reservado y clandestino para convertirse en un producto masivo que sería celebrado como una revolución sexual, equiparando falsamente la exhibición del cuerpo femenino con la emancipación de las mujeres. Desde entonces, en la cultura popular se ha ido consolidando un canon estético femenino hipersexualizado, fruto de lo que la literatura ha denominado “pornograficación” o “pornificación cultural”, discurso que convierte en atractivas las imágenes y prácticas de la industria de la explotación sexual y la pornografía. Este texto propone una reflexión teórica feminista sobre el fenómeno y ofrece un apartado empírico que ilustra la normalización de este paradigma en las industrias culturales.
¿Por qué los hombres pueden excitarse ejerciendo violencia?
Authors: Alario Gavilán Mónica
Published: May 2022

En este artículo se presentan algunos resultados de una investigación sobre cómo la pornografía colabora en la reproducción de la violencia sexual contra las mujeres por medio de la construcción del deseo sexual de los hombres. En dicha investigación se han identificado tres estrategias relativas a la reproducción de dicha violencia, que están operando tanto dentro de la pornografía como a nivel social: la invisibilización de la violencia sexual en tanto que violencia y su normalización y erotización como si fuera sexo, la erotización directa de la violencia sexual en tanto que violencia y la vinculación entre sexualidad y desigualdad de poder entre hombres y mujeres. En este artículo se analiza el funcionamiento de estas tres estrategias y se proponen caminos que permiten avanzar hacia su desactivación, teniendo como horizonte la construcción de sociedades en que se garantice el cumplimiento del derecho humano de mujeres y niñas a una vida libre de violencia.
Violencia íntima en parejas gays
Authors: Sánchez-Domínguez Juan Pablo , Castillo-Arcos Lubia del Carmen , Juan Martínez Berenice
Published: May 2022

En este artículo se presentan los resultados de un estudio llevado a cabo en dos etapas; la primera fase consistió en una revisión teórica acerca de la violencia en parejas íntimas gays, con el objetivo de contextualizar el estado que guarda la investigación en este ámbito, al tiempo de reconocer los mecanismos asociados para su ejecución; la segunda parte, mediante una entrevista a profundidad se obtuvieron datos empíricos que a la postre permitieron el análisis de un caso. Como resultado, se identificaron en la historicidad del sujeto en cuestión diversos mecanismos y formas de violencia sutiles que se ponen en marcha en la intimidad de la relación. En este mismo contexto, se logró reconocer la intersección de las categorías clase y sexualidad como elementos claves que coadyuvan a complejizar el fenómeno de la violencia en parejas homosexuales. En conclusión, la violencia entre pareas gays suelen ser en algunas sociedades mucho más recurrentes que en parejas heterosexuales, además de presentar diversas peculiaridades en su manifestación que exigen mayores abordajes investigativos.
Contrahistorias: una propuesta a partir de la bioética narrativa para contrarrestar el discurso de odio
Authors: Manchola-Castillo Camilo
Published: May 2022

Propósito/Contexto. Este artículo propone las contrahistorias con base en la bioética narrativa como dispositivos para contrarrestar el discurso del odio.

Metodología/Enfoque. Investigación cualitativa a partir de un paradigma hermenéutico y reflexivo, dividida en tres momentos metodológicos: revisión de la bioética narrativa, análisis del discurso de odio, establecimiento de una relación entre la bioética narrativa y el discurso del odio y proposición de contrahistorias como antídotos del discurso de odio.

Resultados/Hallazgos. Paradójicamente, la bioética narrativa y el discurso de odio comparten una característica importante: ambos son conscientes del poder que las historias encarnan para los seres humanos; sin embargo, los dos usan esas historias de manera diametralmente opuesta, mientras la bioética narrativa defiende la dignidad y la justicia social, el discurso de odio ataca estos dos elementos.

Discusión/Conclusiones/Contribuciones. La tercera onda de la bioética narrativa tiene el potencial de contrarrestar el discurso de odio a través de la creación de historias más allá de las historias que defiendan la dignidad y la justicia social, para esto es necesario educar y preparar a las personas para que no solo generen historias que persuadan, sino que sean politizadas y aboguen por la dignidad de los demás seres humanos.

The purpose of this research is to seek the opinions of teacher candidates in order to develop the spiritual and creative potential of future teachers in the ‘school-university’ system. This research was carried out using the qualitative research method. The participant group of the research consisted of 40 pre-service teachers who were studying at the faculty of education in the 2021–2022 academic year and agreed to participate in the study voluntarily. Research data were collected through the semi-structured interview form developed by the researchers. As a result of the research, it has been determined that the spiritual well-being and creative potential of the teacher candidates are at a moderate level. In addition, pre-service teachers suggested that courses should be given in universities in order to develop their spiritual and creative potentials. Some of the teachers offered suggestions to make practices to develop their spiritual and creative potential in the school-university environment and to benefit from experienced teachers in this system. In addition, teacher candidates stated giving importance to personal development and participating in personal development seminars as suggestions for the development of their spiritual and creative potentials. In line with the results of the research, the necessity of carrying out applications for the development of the spiritual well-being and creative potential of teacher candidates in the school-university system has arisen.

Left Behind: The Multiple Impacts of Covid-19 on Forcibly Displaced People
Authors: Valette Delphine , Korobkova Natalia
Published: May 2022

To better understand vaccination barriers and the impacts of Covid-19 on forcibly displaced persons (FDPs, i.e. refugees, and internally displaced persons (IDPs)), World Vision International carried out a multi-country survey of refugee populations in Colombia, Peru, Brazil, Uganda, the Democratic Republic of the Congo (DRC), Jordan, and Turkey, and IDPs in Venezuela. The survey found that a combination of barriers led to FDPs falling through the gaps of national Covid-19 vaccination campaigns, despite their heightened vulnerability to Covid-19 infection and transmission. Only one person out of the 1,914 FDPs surveyed reported receiving a Covid-19 vaccine. The survey also highlighted the significant indirect impacts of the pandemic on forcibly displaced families, and children specifically, with the socioeconomic aftershocks of the Covid-19 pandemic worsening displaced children’s deprivations across health and nutrition, protection support, and education.
Anti-Migrant Authoritarian Populism and the Global Vaccination Challenge
Authors: Proudfoot Philip , Rohwerder Brigitte
Published: May 2022

This article explores the ways in which anti-migrant and refugee discourses and policies have flourished throughout the Covid-19 pandemic despite dominant global public health concerns, especially around vaccines. Our argument is that pre-crisis authoritarian, populist, and nativist political tendencies have proven remarkably resilient, interacting readily with the pandemic to further justify a rolling back on refugee and migrant rights. These tendencies risk, in several contexts, undermining the comprehensive global vaccination effort needed to combat the pandemic.
The Health of People with Disabilities in Humanitarian Settings During the Covid-19 Pandemic
Authors: Hunt Xanthe , Morgon Banks Lena
Published: May 2022

People with disabilities are at a higher risk of poor health outcomes and face barriers to accessing health services, which may be exacerbated in humanitarian settings and during the Covid-19 pandemic. This scoping review explores how best to protect the health of people with disabilities in humanitarian contexts during the Covid-19 response. Forty-eight articles across the peer-reviewed and grey literature were identified. Key challenges include a lack of accessibility of mainstream Covid-19 prevention and response measures, disruptions to routine care pathways for people with disabilities, and double discrimination based on disability and displaced status. Specific priority areas include continuity of basic and specialised services, prioritisation of women and children with disabilities, the need to adapt mainstream recommendations for the Covid-19 response to be disability- and humanitarian-setting inclusive, and strengthening data systems.
Covid-19’s Effects on Contraceptive Services Across the Humanitarian–Development Nexus
Authors: Jacobi Lily , Rich Sarah
Published: May 2022

Sexual and reproductive health (SRH) services, including contraception, save lives in humanitarian emergencies. To document practitioners’ perceptions of the effects of the Covid-19 pandemic on contraceptive programming in humanitarian settings and across the humanitarian–development nexus, the Women’s Refugee Commission conducted 29 key informant interviews with respondents from non-governmental organisations, the United Nations, and government ministries. Disruptions to contraceptive services included closures or repurposing of health facilities, limited availability of health providers, supply chain interruptions, restricted service delivery modalities, and lower demand for services. Adaptations to sustain services included telemedicine, task-shifting and sharing, community-based service delivery, and other innovations. Underlying factors affecting the types and extent of disruptions and adaptations included emergency preparedness for SRH, decision makers’ prioritisation of SRH services, funding, and coordination. Findings reinforce the need to build awareness that SRH services, including contraception, are lifesaving and essential in humanitarian settings, and to improve preparedness, including bridging gaps between humanitarian and development actors.

However, little empirical evidence is available in sub-Saharan Africa that examines the relationship between commercialisation pathways taken by farmers and welfare outcomes, such as farm income and asset accumulation. This paper fills this gap by taking advantage of data from two rounds of surveys conducted in 2018 and 2020 of smallholder farmers in Zimbabwe.
First fossil record of Mustelus aff. punctulatus Risso, 1826: new evidence for a smooth-hound shark population in the Late Miocene North Sea Basin

Mustelus is a problematic genus in palaeoichthyology. Due to the scarcity of fossil teeth, relative homogeneity in tooth morphology and the lack of published extant dentitions, the early history of smooth-hound sharks remains poorly understood. Recently, two teeth were collected in the Tortonian Deurne Member (Diest Formation) near Antwerp (Belgium). Surprisingly, a detailed SEM-based comparison with the extant North-Eastern Atlantic species (Mustelus mustelus, Mustelus asterias, Mustelus punctulatus) allowed assigning the fossil teeth to Mustelus aff. punctulatus. Today, this species is largely restricted to the Mediterranean and lies at the very base of the placental Mustelus clade evolution. Until now, this species remained unrecognized in the existing fossil record. By (re)evaluating isolated teeth from other upper Miocene localities in the southern North Sea Basin, the existence of a widely distributed population of Mustelus aff. punctulatus for the late Serravallian and the Tortonian can now be postulated. Thereafter, the species disappeared from the North Sea. Until today, no single record of Mustelus punctulatus is known from the Mediterranean predating the Messinian Salinity Crisis. Therefore, it is hypothesized that the current populations have their origin in southward migration from northern, Atlantic populations, and this probably after the “Zanclean Flooding”.
Geometria escolar nos anos iniciais

O presente artigo toma categorias construídas pelos estudos históricos de relações entre geometria e desenho que marcaram os diferentes movimentos do currículo de matemática para o ensino de geometria, proposto ao curso primário, do século XIX até meados do século XX. Utilizam-se como fonte regulamentações e manuais escolares de cada período que tiveram como intenção atender às normativas. Dialogam com o passado os resultados de pesquisas atuais, que destacam perspectivas para o ensino de geometria no século XXI e sua inserção na BNCC. Nenhum dos três movimentos foi mantido da maneira como foi prescrito, entretanto, há vestígios deles no cenário do século XXI. A história dos movimentos de construção de saberes para o ensino de geometria pode trazer contribuições e frutíferas reflexões para pensar, analisar e desencadear proposta e ações pertinentes para práticas pedagógicas de um ensino de geometria.

Este texto tem por objetivo caracterizar saberes do campo profissional do professor que ensina matemática. Buscar-se-á responder à seguinte questão: Que “tabuada para ensinar” pode ser caracterizada, a partir da análise das orientações de Irene de Albuquerque em seu manual Metodologia da Matemática (1951)? A pesquisa, de cunho qualitativo, bibliográfica e documental, embasa-se em autores que defendem dois tipos de saberes na constituição das profissões do ensino e da formação, saberes a e para ensinar, e volvendo para a matemática, de autores que definem matemática a e para ensinar a partir dos primeiros referenciais. Para as análises teórico-metodológicas, apoiar-se-á em autores que consideram que a interpretação de uma informação em saber ocorre por etapas. Como resultados foram caracterizados elementos de uma tabuada para ensinar em dois grupos, dos saberes sobre a tabuada a ensinar e dos saberes sobre as práticas de ensino da tabuada.
Anti-angiogenic drugs in cancer therapeutics: a review of the latest preclinical and clinical studies of anti-angiogenic agents with anticancer potential

Cancer is a group of diseases with significant morbidity and mortality. In cancer cells, where energy requirements are exceptionally high, angiogenesis, which is the sprouting of new blood vessels from pre-existing ones, is an important process for tumour survival and progression. Hence, extensive research in recent years focuses on the discovery of new anticancer drugs that target angiogenesis. Several methodologies have been developed preclinically, including the inhibition of pro-angiogenic factors and their receptors via micromolecular agents or monoclonal antibodies and the inhibition of other compensatory pathways beyond the traditional angiogenic ones. The purpose of the literature review is to present new anticancer drugs that target the process of angiogenesis and have been under preclinical or clinical investigation during the last five years. Many new anticancer drugs targeting angiogenesis are identified in the literature. The results of the in vitro and in vivo evaluation of these drugs show that, apart from inhibiting angiogenesis, they also affect cancer cell proliferation and tumour growth. Recent clinical studies show that these drugs increase the overall or disease-free survival of patients, even those with persistent, chemotherapy-resistant and metastatic types of cancer, although treatment-related side effects are not uncommon. Drugs that target the process of angiogenesis are likely to be the future of anticancer therapy, especially in cases where more traditional treatments do not produce the desired results and where combination regimens of anti-angiogenic agents with standard chemotherapeutics increase patient survival.

O elevado crescimento populacional, gera incertezas quanto a segurança alimentar. Fato que alinha-se com problemas de escassez e degradação de recursos, como água e solo. Assim, várias técnicas são empregadas almejando alcançar patamares superiores de produtividade, destacando-se a irrigação e o processo de automação. Neste sentido, o presente trabalho teve como objetivo fornecer informações sobre a automação de forma ampla e enfatizar nos sistemas agropecuários com destaque na irrigação. O trabalho desenvolve-se no formato de uma revisão de literatura. Inicia-se pela automação, com apresentação do conceito e histórico, além de aspectos sobre o processo. No setor agropecuário, automação e tecnologia da informação culminaram na chamada agricultura 4.0. Com relação a automação na irrigação, o processo permite o manejo assertivo do sistema, utilizando-se de programações que consideram variáveis como a umidade do solo e do ar. Estes sistemas podem ser adquiridos comercialmente, ou confeccionados através de plataformas como o arduino. Portanto, destaca-se que o advento da automação com a evolução das práticas agropecuárias, levaram processos como a irrigação a novos níveis de tecnologia, permitindo o controle em tempo real. Assim, apesar dos diferentes níveis e formas de automação, o processo é uma medida que possibilita elevados ganhos em produtividade e eficiência.

Waterproof coal pillar in the underground reservoir is affected significantly by inclination loads and water erosion. Comprehensive understanding of the influence of moisture content and inclination angle on the mechanics properties and microfracture behavior of coal specimens plays an important role for revealing the instability mechanism of waterproof coal pillar. In this paper, a new modified combined compression and shear test (MC-CAST) system was firstly developed for achieving the specimen inclined loading and then used to carry out the inclined uniaxial compression test of water-bearing coal specimens at the inclination angle of 0°, 5°, 10°, and 15° and the moisture content of 0%, 2.42%, 5.53%, 7.55%, and 10.08%. The mechanical and microfracture behaviors of water-bearing coal specimens were analyzed and discussed by AE techniques and SEM. Research results indicate that ① the peak shear stress, peak strength, and elastic modulus of coals showed obvious moisture content weakening effect, and the weakening effect was more significant at larger inclination angle; ② the peak strength and elastic modulus decreased nonlinearly as inclination angle increased, of which decreasing amplitude was greater at high moisture content than that at low moisture content; ③ the peak shear stress gradually increased with the increasing inclination angle for 0%-7.55% moisture content, while it increased first and then decreased, and reached the maximum value at 10° inclination angle for 10.08% moisture content; ④ the stress thresholds of crack closure, initiation, and damage of coal specimens decreased gradually with the increase of moisture content and inclination angle, but the ratio of above three thresholds to their corresponding peak strength was basically unchanged; and ⑤ the erosion-stripping effect of bound water and pore pressure effect of free water, respectively, caused initial damage and secondary superposition damage of coal specimens before and after inclination loading test. Combining with the promotion effect of additional shear stress on crack initiation, propagation, and coalescence, the coupling effect of the above three factors was the fundamental reason for the strength deterioration of water-bearing coals under inclined loading. The research results can provide an important basis for the strength and stability evaluation of waterproof coal pillars of underground reservoirs in ecologically fragile areas.
