Terahertz photonic crystal fiber polarization rotator
Authors: Hameed Mohamed Farhat O. , Esmail Mohamed Saleh M. , Obayya Salah S. A.
Published: July 2020

Polarization control of terahertz (THz) waves is highly required due to their immense practical applications. Most of the THz polarization rotators in the literature depend on the transmission or reflection from metamaterials or all-dielectric metasurfaces. There is also a lack of THz polarization handling waveguides due to the material absorption in this frequency regime. In this paper, a THz photonic crystal fiber (PCF) polarization rotator (PR) is introduced and analyzed for the first time to the best of our knowledge. The suggested PCF-PR has an asymmetric porous core to decrease the material losses and increase the hybridness of the two polarized modes. Therefore, high polarization conversion ratio of 80.7% is achieved with a good crosstalk of

Published: July 2020

In this Letter, we report the experimental observations of a tunable curved photonic nanojet (photonic hook) generated by a 5 µm polydimethylsiloxane microcylinder deposited on a silicon substrate and illuminated by 405 nm laser beam. A moveable opaque aluminum-mask is mounted in front of the microcylinder implementing partial illumination and imparting spatial curvature to the photonic nanojet. Experimental results of main parameters (tilt angle, width, and intensity) of emerging photonic hooks exhibit close agreement with numerical predictions of the near-field optical structures. The experimentally measured full widths at half-maximum of photonic hooks are

Realization of high-dimensional frequency crystals in electro-optic microcombs
Authors: Hu Yaowen , Reimer Christian , Shams-Ansari Amirhassan , Zhang Mian , Loncar Marko
Published: July 2020

Crystals are ubiquitous in nature and are at the heart of material
research, solid-state science, and quantum physics. Unfortunately, the
controllability of solid-state crystals is limited by the complexity
of many-body dynamics and the presence of defects. In contrast,
synthetic crystal structures, realized by, e.g.,  optical lattices,
have recently enabled the investigation of various physical processes
in a controllable manner, and even the study of new phenomena. Past
realizations of synthetic optical crystals were, however, limited in
size and dimensionality. Here we theoretically propose and
experimentally demonstrate optical frequency crystal of arbitrary
dimensions, formed by hundreds of coupled spectral modes within an
on-chip electro-optic frequency comb. We show a direct link between
the measured optical transmission spectrum and the density of states
of frequency crystals in one, two, three, and four dimensions, with no
restrictions to further expanding the dimensionality. We demonstrate
that the generation of classical electro-optic frequency comb can be
modeled as a process described by random walks in a tight-binding
model, and we have verified this by measuring the coherent
distribution of optical steady states. We believe that our platform is
a promising candidate for exploration of topological and quantum
photonics in the frequency domain.
Envelhecimento de homens gays brasileiros

Published: July 2020

O presente artigo objetivou analisar as representações sociais de homens gays brasileiros sobre a velhice LGBT, com base na Teoria das Representações Sociais. Foi utilizada uma entrevista semiestruturada realizada com homens gays residentes de todo o Brasil. Utilizou-se a Classificação Hierárquica Descendente (CHD) e a Análise Prototípica para a análise das representações apreendidas. Os resultados obtidos demonstram o enraizamento das representações em aspectos negativos da velhice e a negação da sexualidade nessa fase da vida, onde estes reforçam o preconceito e corroboram com a dupla discriminação vivenciada por idosos LGBTs.
Los reformuladores de recapitulación en el corpus Preseea de Granada
Authors: Ruiz González Natalia
Published: July 2020

La reformulación recapitulativa presenta en un nuevo miembro discursivo una síntesis o resumen de un elemento expuesto previamente o una serie de ellos. Lo más común es que se lleve a cabo mediante la marcación discursiva y esta tiende a variar según el lugar y las características sociales de los hablantes que la emplean. Para comprobar cómo es el funcionamiento de estas unidades y su distribución social en el español de Granada, hemos llevado a cabo un estudio sociolingüístico basado en el corpus Preseea de la ciudad andaluza. Los resultados arrojan que la edad y el nivel educativo se revelan como factores clave en el uso de los recapitulativos, siendo superior cuanto más años y mayor nivel de estudios posee el hablante. Además, en fin es el reformulador preferido para cumplir esta función, abarcando casi un 40% de los casos en que aparece este grupo de marcadores discursivos.
O teatro de Gabriela da Cunha e a dança de Maria Eugenia
Authors: Oliveira Nicolas Pelicioni de , Aquati Cláudio
Published: July 2020

No presente artigo desenvolvemos uma crítica acerca do trabalho que Maria Eugenia, dançarina brasileira contemporânea, faz sobre danças populares do Brasil. Para tanto, empregamos as reflexões de Walter Benjamin, em especial as contidas nos ensaios “A obra de arte na época da possibilidade de sua reprodução técnica”, e “O contador de histórias”, e a filosofia do teatro proposta por Jorge Dubatti, na qual ele preconiza uma formalização crítica quanto à abordagem de artes teatrais que têm como característica indissociável a incapturabilidade. Por essa perspectiva, entendemos que a crítica de Machado de Assis acerca da atuação da atriz Gabriela da Cunha já se alinha a aspectos da teoria crítica sobre o teatro que posteriormente será desenvolvida por J. Dubatti. Por esse motivo, tomamos essa crítica de Machado de Assis como modelo para a nossa crítica acerca do trabalho da dançarina Maria Eugenia, uma vez que a dança é uma prática teatral incapturável, que sequer conta com um texto escrito.

Published: July 2020

Este texto apresenta a investigação sobre a obra 7 Canções de Dinorá de Carvalho, obra inédita da compositora encontrada na Coleção Dinorá de Carvalho do CDMC/UNICAMP. O ciclo em questão não está presente no Catálogo de Obras da compositora (FERREIRA, 1977), o que nos leva a inferir que foi criado entre 1977 (ano da edição do catálogo) e 1980, ano do falecimento da compositora. Expomos a descrição do material manuscrito encontrado, a investigação sobre a autoria das cópias manuscritas, um breve histórico da obra, retificação de datas, assim como uma análise do conteúdo musical dos testemunhos modelos. Este trabalho tem como escopo os trabalhos de Maria Caraci Vela (1995), James Grier (1996), César Nardelli Cambraia (2005) e Carlos Alberto Figueiredo (2014). Como considerações finais, percebe-se esta obra como o resultado de um processo contínuo de criação e aponta a possibilidade de uma futura edição crítica e publicação desta e outras obras da compositora.
Territ´órios inexatos
Authors: Visnadi Fábio
Published: July 2020

O artigo é o resultado parcial de investigações realizadas acerca de paradigmas de espacialidade na arte conceitual, com base em uma metodologia experimental que procura esboçar uma morfologia de tal gênero artístico através da categorização dos eixos de desmaterialização e descentralização do objeto artístico em torno do espaço e tempo. No presente escrito, investiga-se a maneira como a espacialidade pode se manifestar dentro da arte conceitual através de três possibilidades: nos eixos limítrofes, esquadrinha-se a obra “Le socle du monde” de Piero Manzoni, declaração do artista italiano de que o mundo inteiro constituía uma obra de arte (representando, portanto, uma espécie de geografia absoluta), e “The space between pages 29 & 30”, de Robert Barry, espécie de númeno que abstrai a intuição artística em prol de um espaço impossível. Nos meridianos entre esses hemisférios que variam do território absoluto ao território impossível, pesquisa-se a indeterminação espacial em obras que não contam com uma fronteira espacial pré-definida em exemplares de Vito Acconci, Guy Debord, Richard Long, Christo e Jeanne-Claude.
Três percursos e um desvio para um mesmo fim
Authors: Campos Aurora dos
Published: July 2020

No artigo discorro sobre o projeto performativo “Três Percursos e um desvio para um mesmo fim”, realizado em 2019 no âmbito da investigação “Dramaturgias do Quotidiano. Especulações sobre a dimensão ficcional do real” desenvolvida no Mestrado em Arte e Design para o Espaço Público da Universidade do Porto. O trabalho teve por base os trajetos diários que utilizava para levar meu filho a creche, através de ruas do Porto. A proposta é constituída por quatro percursos-experiência elaborados com instruções para serem vivenciados por um grupo de espectadores-participantes. Para cada percurso, usei procedimentos distintos para explorar questões, tais como: a co-existência de tempos distintos, o percurso pensado como narrativa, a multiplicidade de olhares sobre um trajeto, a ideia e do desvio como campo de possibilidades. Na contramão do automatismo do quotidiano “Três percursos e um desvio para um mesmo fim” intenciona conectar os participantes a dimensão da experiência, da imaginação e a um tempo subjetivo. No artigo discuto as questões de cada percurso-experiência e convido o leitor a uma espécie de deriva sobre os espaço em trânsito que proponho.

Published: July 2020

Idealnya semua kehidupan sekolah baik di kelas dan luar kelas dapat mendukung penanaman nilai karakter terhadap siswa. Di satu sisi pada tahun 2002, disahkan UU No. 23 Tahun 2002 tentang Perlindungan Anak. Undang-undang ini dimaksudkan untuk memberikan perlindungan terhadap anak sebagai generasi penerus bangsa. Pemberian hukuman sebagai bentuk pendidikan karakter di sekolah kerap dibenturkan dengan ketentuan pidana dalam Pasal 77 UU No. 23 Tahun 2003 tentang Perlindungan Anak, sehingga terdapat guru yang dipidanakan karena pola pendidikan karakter yang diberikan dipahami sebagai bentuk diskriminasi yang merugikan anak dari aspek moril dan materiil. Penelitian ini menggunakan metode penelitian kuantitatif. Dari hasil dan pembahasan diketahui bahwa sanksi pidana memiliki dampak sampingan terhadap rasa takut, rasa khawatir, rasa apatis, dan rasa trauma dalam melaksanakan pendidikan karakter.

Phraseology in a cross-linguistic perspective: A diachronic and corpus-based account
Authors: Gisle Andersen
Published: July 2020

English exerts great influence on other languages at the lexical level, as seen from extensive borrowing of terminology and everyday words into many languages (i.e. Anglicisms such as swap, blog, etc.). Although much less studied, it is also clear that the “phrasicon” (Granger, Sylviane. 2009. Comment on: learner corpora: A window onto the L2 phrasicon. In Andy Barfield & Henrik Gyllstad (eds.),Researching collocations in another language. multiple interpretations, 60–65. Houndmills: Palgrave Macmillan) of a language can similarly be affected by such external influence. This paper investigates “the largely unexplored area of phraseological borrowing” (Fielder, Sabine (2017) Phraseological borrowing from English into German: Cultural andpragmatic implications. Journal of Pragmatics 113: 89–102, 90) by introducing the diachronic-contrastive corpus method and exemplifying it with reference to a set of expressions that have been considered the products of language contact between English and Norwegian. I argue that the proposed corpus method can be used efficiently for investigating phraseology across time, for shedding light on the question of whether cross-linguistically parallel structures are the result of borrowing or parallel developments, and – importantly – as a vehicle for rejecting preconceived ideas about a form’s alleged origin in English.
Modelling and multi-objective optimization for simulation of hydrogen production using a photosynthetic consortium
Authors: Hernández-Melchor Dulce J. , Camacho-Pérez Beni , Ríos-Leal Elvira , Alarcón-Bonilla Jesus , López-Pérez Pablo A.
Published: July 2020

This study was aimed at finding the optimal conditions for hydrogen production based on statistical experiments and using a simulation approach. A Plackett–Burman design and steepest ascent were used to screen the key factors to obtain the best hydrogen concentration. According to the regression analysis, cysteine, acetate, and aeration had the best effect. The optimal conditions, using the method of steepest ascent, were aeration (0.125 L/min), acetate (200 mg/L), cysteine (498 mg/L). Once this was determined, an experiment with more than two factors was considered. The combinations: acetate + cysteine without aeration and cysteine without aeration increased hydrogen concentration. These last two criteria were used to validate the dynamic model based on unstructured kinetics. Biomass, nitrogen, acetate, and hydrogen concentrations were monitored. The proposed model was used to perform the multi-objective optimization for various desired combinations. The simultaneous optimization for a minimum ratio of cysteine-acetate improved the concentration of hydrogen to 20 mg/L. Biomass optimized the concentration of hydrogen to 11.5 mg/L. The simultaneous optimization of reaction time (RT) and cysteine improved hydrogen concentration to 28.19 mg/L. The experimental hydrogen production was 11.4 mg/L at 24 h under discontinuous operation. Finally, the proposed model and the optimization methodology calculated a higher hydrogen concentration than the experimental data.
An expandable radio collar for monitoring young terrestrial mammals
Authors: Santos Eduardo G. , Aguiar Ludmilla M. S. , Machado Ricardo B.
Published: July 2020

Although radio collars are widely applied in movement ecology, their use in animals with changing neck circumferences is challenging. We are proposing a model of a simple, cheap, and expandable collar that is suitable for the monitoring of young terrestrial mammals. We tested the collar on young crab-eating foxes. There was no register of injuries caused by the collar to the tagged animals, and they functioned appropriately. Thus, we hope this note will encourage further researchers to use our method to monitor the movement patterns of young animals, not only for canids but also for other species of terrestrial mammals.

Northern Connections: Interregional Contacts in Bronze Age Northern and Middle Sweden
Authors: Ojala Karin , Ojala Carl-Gösta
Published: July 2020

This article examines northern connections in the Nordic Bronze Age, focusing on interregional contacts in middle and northern Sweden. In the article, we argue that it is important to incorporate a northern perspective in the discussions about the Scandinavian Bronze Age and its networks. We focus on the Mälaren Valley region, especially the province of Uppland, and the northern parts of Sweden, in particular the coastal areas of northern Sweden. We discuss some aspects of the archaeological material, which have been used in earlier discussions of interregional contacts in middle and northern Sweden during the Bronze Age, such as the Håga mound outside of Uppsala, and burial cairns and bronze artefacts in northern Sweden. Furthermore, we discuss eastern contacts with areas in present-day Finland and Russia, and how these have been interpreted in middle and northern Sweden. In our view, there is a need to critically examine interregional contacts and the construction of regional entities and borders in the Bronze Age. In order to better understand the relations between north and south, it is necessary to critically examine the research history behind the present-day conceptions of regions and borders, as well as the political dimensions and power relations involved.

Das Oppidum von Manching ist für die Spätlatènezeit seit langem als einer der wenigen Fundplätze bekannt, aus dem menschliche Skelette und Skelettreste, noch dazu in großer Anzahl, vorliegen. Schon G. Lange hat bei seiner Bearbeitung der Funde aus den Jahren 1955–1973 auf der Basis der Anthropologie gewisse Regeln erkannt. Der vorliegende Beitrag geht von den „Gruben“ mit Menschenknochen von der Manchinger „Südumgehung“ aus, die von H. Lorenz detailliert vorgelegt wurden, und diskutiert, inwieweit sich für diese Befunde und konkret ihre Inventare Regelhaftigkeiten oder zumindest Tendenzen rekonstruiert lassen. Berücksichtigt werden auch die Themen der „Abfallentsorgung“ und des Erscheinungsbildes der Siedlung in der Spätlatènezeit.
THE EFFECTIVENESS OF MYOFASCIAL RELEASE OVER STRETCHING ON PAIN AND RANGE OF MOTION AMONG FEMALE COLLEGE STUDENT WITH PIRIFORMIS SYNDROME
Authors: Subramanian Shenbaga Sundaram
Published: July 2020

Title: The Effectiveness of Myofascial Release over Stretching on Pain and Range of Motion among Female College Students with Piriformis Syndrome.Background & Aim: Piriformis syndrome is a painful neuromuscular disorder that occurs when the piriformis muscle irritates and/or compresses the proximal sciatic nerve. Prolonged sitting position is the foremost cause of piriformis tightness in sedentary population that may eventually leads to piriformis syndrome. The incidence of piriformis has been reported to be six times more prevalent in female than in males. Piriformis tightness will cause reduced in range of motion as well as limitations in walking, sitting and even running. Moreover, individuals will also feel pain at their butt muscles which could be frustrating. Thus, the aim of this study is to determine the effectiveness of myofascial release over stretching on pain and range of motion among female college students with piriformis syndrome.Methods: twenty subjects aged between 19 to 25 years old with tight piriformis muscle for 4 weeks will make a part of the study based on the inclusion and exclusion criteria. Subjects are divided and will undergo myofascial release and stretching treatment for 4 weeks twice in a week. At the beginning before the session the pain score and goniometer measurements will be recorded.Conclusion: Group 1 and Group 2 are beneficial in reducing pain and range of motion. Therefore, there are no significant effect of myofascial release over stretching between the two groups.Keywords: Myofascial release, college students, piriformis syndrome, stretching, goniometer, pain score.

Published: July 2020

Context:

Growth hormone (GH) deficiency is a common late effect of cranial irradiation. However, concerns have been raised that GH treatment might lead to an increased risk of a second neoplasm (SN).

Objective:

To study the impact of GH treatment on the risk of SN in a French cohort of survivors of childhood cancer (CCS) treated before 1986.

Design and setting:

Cohort study and nested case–control study.

Participants:

Of the 2852 survivors, with a median follow-up of 26 years, 196 had received GH therapy (median delay from cancer diagnosis: 5.5 years).

Main outcome measures:

Occurrence of SN

Results:

In total, 374 survivors developed a SN, including 40 who had received GH therapy. In a multivariate analysis, GH treatment did not increase the risk of secondary non-meningioma brain tumors (RR: 0.6, 95% CI: 0.2–1.5, P = 0.3), secondary non-brain cancer (RR: 0.7, 95% CI: 0.4–1.2, P = 0.2), or meningioma (RR: 1.9, 95% CI: 0.9–4, P = 0.09). Nevertheless, we observed a slight non-significant increase in the risk of meningioma with GH duration: 1.6-fold (95% CI: 1.2–3.0) after an exposure of less than 4 years vs 2.3-fold (95% CI: 0.9–5.6) after a longer exposure (P for trend = 0.07) confirmed by the results of a case–control study.

Conclusion:

This study confirms the overall safety of GH use in survivors of childhood cancer, which does not increase the risk of a SN. The slight excess in the risk of meningioma in patients with long-term GH treatment is non-significant and could be due to difficulties in adjustment on cranial radiation volume/dose and/or undiagnosed meningioma predisposing conditions.
Analysis of the correlation between the themes of the public psychodrama at CCSP and the newspaper headlines
Authors: Batista Marcia Almeida , Nascimento Adriana
Published: July 2020

The public psychodramas in the city of São Paulo take place at the Centro Cultural São Paulo (CCSP) and intend to create public spaces that accommodate different subjectivities, as well as to exchange ideas, values, and experiences of life as of the collective construction of the dramatized stories. This article correlates the themes that were dramatized at those sessions available at the website from the Brazilian Psychodrama Association (FEBRAP) during 2015, 2016, and 2017 with the main headlines of the two local newspapers O Estado de São Paulo and Folha de São Paulo. The purpose was to investigate if the public psychodrama sessions could build citizenship within the members of the session. It was verified that the sessions that happened at the CCSP were significant to this construction by opening discussion of current social issues even though there were greater correlations between the themes as a whole, than the temporal coincidence between themes and the weekend’s headlines.

Published: July 2020

O presente trabalho investiga a influência do fenômeno da transgeracionalidade no ciclo de vida familiar de casal com filhos pequenos. A partir dos dados levantados por meio de genogramas, foi possível obter uma leitura sistêmica a respeito da família de origem de cada um dos cônjuges, bem como da família nuclear por eles constituída. Durante as sessões de terapia de casal, foi trabalhado, entre outros temas, o conceito de diferenciação do self, possibilitando ao casal o entendimento acerca da origem de seus problemas conjugais, os quais emergiram após o nascimento das filhas. Como consequência, o casal pôde vivenciar mudanças evolutivas na relação conjugal, confirmando o que a terapia boweniana diz sobre o entendimento ser o veículo de cura.

The natural genetic diversity of agricultural species is an essential genetic resource for breeding programs aiming to improve their ecosystem and production services. A large natural ecotype diversity is usually available for most grassland species. This could be used to recombine natural climatic adaptations and agronomic value to create improved populations of grassland species adapted to future regional climates. However describing natural genetic resources can be long and costly. Molecular markers may provide useful information to help this task. This opportunity was investigated for Lolium perenne L., using a set of 385 accessions from the natural diversity of this species collected right across Europe and provided by genebanks of several countries. For each of these populations, genotyping provided the allele frequencies of 189,781 SNP markers. GWAS were implemented for over 30 agronomic and/or putatively adaptive traits recorded in three climatically contrasted locations (France, Belgium, Germany). Significant associations were detected for hundreds of markers despite a strong confounding effect of the genetic background; most of them pertained to phenology traits. It is likely that genetic variability in these traits has had an important contribution to environmental adaptation and ecotype differentiation. Genomic prediction models calibrated using natural diversity were found to be highly effective to describe natural populations for almost all traits as well as commercial synthetic populations for some important traits such as disease resistance, spring growth or phenological traits. These results will certainly be valuable information to help the use of natural genetic resources of other species.

El siguiente artículo se centra en el modo en el que Ariadna y Ka, los dos personajes en el relato breve «Hora de Partir» (2007), del escritor ecuatoguineano César A. Mba Abogo, resisten una categorización racial y social dominante mediante la relación de amor que mantienen en España. Para dicho propósito, me sirvo de la ideología del colorblindness, la cual defiende que la igualdad entre categorías grupales se consigue mediante el tratamiento de las personas como seres individuales con características únicas (Rosenthal et al. 2010: 150). La aplicación de esta teoría al análisis de la narración permite resaltar el proceso de individuación que ambos personajes experimentan, basado en el ensalzamiento de su individualidad. De este modo, este artículo defiende que la relación de amor que ambos mantienen funciona como un espacio literario de resistencia a nivel narrativo desde donde los personajes enfrentan los estereotipos sociales, raciales y políticos sobre los que la categorización grupal está conformada.

Sobre el donjuanismo de don Álvaro, del Duque de Rivas, en constante referencia a Félix de Montemar
Authors: Eugercios Arriero José Luis
Published: July 2020

El don Álvaro de Rivas viene configurado como contrafacción del arquetipo donjuanesco que inaugura Tirso y lleva a plenitud Espronceda en El estudiante de Salamanca. El contraste entre las figuras de don Álvaro y don Félix ilumina al primero como burlador, cierto que a su pesar, y como elemento igualmente subversivo frente al orden sociomoral del antiguo régimen. En sus rígidos cánones hay que buscar las causas de la destrucción del indiano.
La narración como arte total en las novelas y cuentos de Luisa Mercedes Levinson
Authors: Ruiz Sánchez Marcos , Ruiz Sánchez María
Published: July 2020

Los relatos de Luisa Mercedes Levinson se caracterizan por la utilización de múltiples códigos. Resulta significativa en este sentido la presencia en su obra del teatro y de la música. La autora juega con diferentes códigos genéricos: novela sentimental, tragedia, literatura fantástica y cuento realista. La utilización de ciertas técnicas narrativas como el monólogo interior hace, por otra parte, que en ocasiones las fronteras entre verso y prosa parezcan borrarse.

—The gradual transition of the Bazhenov Formation top into the overlying deposits makes it difficult to establish its upper boundary. The problem is aggravated by the lack of core material when the formation is recognized according to the results of geophysical well studies. A comprehensive analysis of geochemical and lithological data and the results of geophysical well surveys enabled us not only to determine the specific structure of the transitional zone from the Bazhenov Formation top to the rocks of the sub-Achimov member, but also to propose the criteria for delineating the upper boundary in the central regions of the West Siberian sedimentary basin within the Khentei hemianteclise, the South Nadym megamonoclise and the Mansi syneclise. Four members are distinguished in the transitional zone of the studied well sections (from bottom to top), which differ in lithological, geochemical and geophysical characteristics: (I) the “coccolithic” upper part of the Bazhenov Formation; (II) transitional member from the upper part of the Bazhenov Formation to the bottom of the sub-Achimov member; (III) transitional member from the bottom of the sub-Achimov member to its lower part; and (IV) the lower part of the sub-Achimov member. Member II is virtually not distinguished within the Khentei hemianteclise and the South Nadym megamonoclise. Member III contains the boundary between zones with different redox conditions. In case member II is distinguished, the upper boundary of the Bazhenov Formation corresponds to its top. To recognize the Bazhenov Formation top, it is necessary to use the integrated analysis results of the lithological and geochemical studies of the well core, and logging data (gamma-ray logging, neutron gamma-ray logging and its variations, lateral logging, and induction logging) when focusing attention mainly on radioactivity.
ХРОНІКА ХЕРСОНСЬКОГО ГЕТТО (1941 р.)
Authors: Kaparulin Yurii
Published: July 2020

Після встановлення нацистського окупаційного режиму в містах України було створено десятки єврейських гетто. Більшість із них досі залишаються «білими плямами» на тлі історії міського простору. У статті розглянуто історію гетто у Херсоні. Встановлено, що від самого початку нацистська адміністрація не планувала довгострокового існування гетто, а його мешканців мали знищити у найкоротші строки.

Актуальність запропонованої теми зумовлено необхідністю вивчення маловідомих сторінок місцевої історії, які мають допомогти осмислити сучасний міський простір із його минулим та сприяти формуванню сучасної політики пам’яті. Історія херсонського гетто десятиліттями залишалася маловідомою широкому загалу і досі не була темою спеціального історичного дослідження. Це можна пояснити низкою об’єктивних факторів. Більшість головних свідків організації та ліквідації гетто знищили нацисти. Гетто існувало дуже короткий час (близько одного місяця) в умовах ізоляції та комендантської години; спілкування його мешканців із іншим населенням міста максимально обмежили. У післявоєнні роки російська влада з політичних міркувань не розглядала трагедію єврейського народу як окрему проблему.

Зібрано та опрацьовано комплекс джерел, які дають змогу охарактеризувати обставини створення гетто, повсякденне життя у ньому та процес його ліквідації.

Визначено, що створювали та ліквідовували гетто члени зондеркоманди 11а айнзацгрупи Д поліції безпеки СД. За наказами нацистів у місті сформували єврейську раду («юденрат»), діяльність якої передбачала облік єврейського населення міста та переведення його до гетто. Прослідковано поведінку та адаптацію мешканців міста до життя в умовах окупації, зокрема зміну їхніх соціальних ролей. Наведено приклади, які свідчать про стратегії виживання і свідомий колабораціонізм.

Published: July 2020

Introduction: This study addresses and evaluates the decrease of antibiotic resistance after introduction of a proposed prevention plan and control complex in the intensive care unit (ICU).

Methods: Data from 1,111 bacteriological analyses, taken from patients who received treatment in the ICU of Ternopil University Hospital from January to August 2015 (group 1) and the same period of 2018 (group II), were included in the study. The complex included measures for the prevention of antibiotic resistance spread and for rational antibiotic use.

Results: We found that resistance to imipenem changed more than other antibacterial drugs, increased by 60% (р ≤ 0.05), which was conditioned predominantly by Pseudomonas aeruginosa isolates for 100%. A decrease in 39% of polyresistant clinical isolates of Klebsiella pneumoniae in patients of groups I and II showed important prognostic value.

Conclusion: A complex of the proposed measures included the division of patients in blocks according to the risk of infectious complications, control of antibiotics administration, adherence to sanitary norms by ICU staff, use of sodium hypochlorite resulting in decrease of pathogenic isolates, and level of antibiotic resistance to specific groups of antibacterial drugs.
"The Hopkins Mongol Case": The Dawn of the Bioethics Movement
Authors: Fost Norman
Published: July 2020

One of the earliest controversies in the modern history of bioethics was known at the time as "the Hopkins Mongol case," involving an infant with Trisomy 21 and duodenal atresia whose parents declined to consent to surgery. Fluids and feeding were withheld, and the infant died of dehydration after 15 days. The child’s short life had a profound impact on the author’s career and that of several others and ultimately led to changes in the care of children and adults with disabilities and the way difficult end-of-life decisions are made in US hospitals today. It also contributed to the growth of the modern bioethics movement and scholarship focused on pediatric bioethics issues.
Ferguson v. City of Charleston Redux: Motivated Reasoning and Coercive Interventions in Pregnancy
Authors: Marshall Mary Faith , Taylor Julia , DeBruin Debra
Published: July 2020

Criminalization of perinatal substance use disorder and other coercive interventions in pregnancy (such as forced cesarean delivery or involuntary hospitalization for bed rest) directly affect the well-being of children and their families and, potentially, of all women of reproductive capacity. Untenable legal and policy approaches that occasion such incursions not only persist but affect a growing number of women. They are antithetical to healthy pregnancies, healthy children, and healthy families; they have the potential to reduce prenatal care seeking, divert attention and resources away from critical mental health and maternal and child support services, and epigenetically affect maternal and infant bonding. Punitive and coercive interventions contravene long-established guidance by professional associations that advocate for public health approaches and ethical frameworks to guide practice. Harmful policies persist because of motivated reasoning by clinicians, members of the judiciary, and ill-informed legislators who rely on personal experience and anecdote rather than evidence to fashion policy. Compounding the problem are inadequate substance use treatment resources and professional associations that choose not to hold their members accountable for violating their ethical obligations to their patients. Pediatricians must advocate for the cessation of coercive interventions within their institutions and their larger communities. All health care professionals should collaborate at the local, state, and national level to provide policymakers and legislators with data emphasizing the negative effects of punitive and coercive policies aimed at pregnant women and their children.
Rites of the Day of Blood (dies sanguinis) in the Graeco-Roman Cult of Cybele and Attis
Authors: Pachis Panayotis
Published: July 2020

The cult of Cybele and Attis was an ancient cult disseminated throughout the entire Roman Empire. Among the rites held by its followers, there were the so-called Day of Blood (dies sanguinis) which, according to the Calendar (or Chronography) of Philocalus (354 CE), was celebrated on 24 March. On this day the worshipers and priests (galli) of Cybele/Attis flagellated themselves until they bled profusely, and with their blood they sprinkled Cybele’s effigy as well as the altars of the temple, while the initiates castrated themselves and offered their testes to the goddess as a real-life imitation of what happened mythologically to the goddess’ consort Attis. The present contribution offers a preliminary systemization of this glaringly maladaptive and quite puzzling belief-behaviour complex in the anthropological and neurocognitive frame of the so-called extreme rituals, highlighting the specific in-group benefit reaped by worshipers and initiates (e.g., community cohesion through costly signalling and credibilityenhancing displays).
Investigation of nonlinearity of longitudinal displacement function from mechanical and geometric characteristics of the plate
Authors: Osadchy N. V , Malyshev V. A , Shepel V. T
Published: July 2020

Layered composite materials are characterized by a high transverse anisotropy and low values of relations between the transverse shear modulus and the modulus of longitudinal elasticity. As a result, the behavior of longitudinal displacements and longitudinal normal stresses differs from the linear law, and the behavior of transverse tangential stresses differs from the parabolic law. The paper presents the analysis of the degree of the plate displacement nonlinearity functions depending on its elastic properties and geometric shape. The article considers a 2D square plate deformation problem. In non-dimensional terms, the authors could received a complete and demonstrative solution. A similar 3D problem is more bulky but it has no principle differences. The study of the degree of the longitudinal displacement nonlinearity functions due to elastic properties and the geometric shape of the deformable plate is based on the finite element method. The potential energy of the deformable plate is expressed through a square form of the variables with coefficients that are polynomials of dimensionless parameters such as plate size, ratio of the elasticity and shear moduli, Poisson's modulus. It is shown that the variational principle reduces the problem to the solution of the system of linear equations. As a result, the subareas of linearity and nonlinearity of the plate longitudinal displacements are constructed with an accuracy acceptable for engineering calculations of 5 %. It is necessary to consider the plate nonlinear longitudinal deformations for a length of the composite plate on order more than its thicknesses. As for steel, nonlinearity is characteristic for quite thick plates. The constructed areas of linearity and nonlinearity of the longitudinal displacements make it possible to construct the strain-stress state models with a smaller number of variables.
