Is a cross-connector beneficial for single level traditional or cortical bone trajectory pedicle screw instrumentation?
Authors: Cornaz Frédéric , Widmer Jonas , Fasser Marie-Rosa , Snedeker Jess Gerrit , Matsukawa Keitaro , Spirig José Miguel , Farshad Mazda
Published: June 2021

The cortical bone trajectory (CBT) has been introduced with the aim of better screw hold, however, screw-rod constructs with this trajectory might provide less rigidity in lateral bending (LB) and axial rotation (AR) compared to the constructs with the traditional trajectory (TT). Therefore, the addition of a horizontal cross-connector could be beneficial in counteracting this possible inferiority. The aim of this study was to compare the primary rigidity of TT with CBT screw-rod constructs and to quantify the effect of cross-connector-augmentation in both. Spines of four human cadavers (T9 –L5) were cropped into 15 functional spine units (FSU). Eight FSUs were instrumented with TT and seven FSUs with CBT pedicle screws. The segments were tested in six loading directions in three configurations: uninstrumented, instrumented with and without cross-connector. The motion between the cranial and caudal vertebra was recorded. The range of motion (ROM) between the CBT and the TT group did not differ significantly in either configuration. Cross-connector -augmentation did reduce the ROM in AR (16.3%, 0.27°, p = 0.02), LB (2.9%, 0.07°, p = 0.03) and flexion-extension FE (2.3%, 0.04°, p = 0.02) for the TT group and in AR (20.6%, 0.31°, p = 0.01) for the CBT-group. The primary rigidity of TT and CBT single level screw-rod constructs did not show significant difference. The minimal reduction of ROM due to cross-connector-augmentation seems clinically not relevant. Based on the findings of these study there is no increased necessity to use a cross-connector in a CBT-construct.
Re-touched
Authors: Eyre Sarah , Hutchinson Xanthe
Published: June 2021

Re-touched is a collaborative project by collage artist Sarah Eyre and fashion photographer Xanthe Hutchinson. Both artists share an interest in the female body, particularly the notion of pleasure in display and gaze between women and the body. The body of work that forms Re-touched combines photographic and collage methods in order to embody a sense of sensuality through the opening up and enfolding of the female form, on set and through the process of collage. The artists position their work within a framework of feminist theory that questions the binary thinking around the gaze. They draw on the writing of Laura U. Marks to bring a haptic quality to their photographic and collage interventions to the image, and in inviting the viewer to be touched by their images. Through this series of photographic collages, they have established a visual and tactile approach that utilizes the body, is collaborative and re-figures the power structures between model, photographer and viewer. Their images offer a way of rethinking and reshaping representations of the female nude.
The provocative aesthetic of Guy Bourdin
Authors: Brett Rachel
Published: June 2021

Fashion and photography are inter-related subjects within a pedagogical discourse incorporating sociological and psychoanalytical approaches. This article will focus on the radical work of Guy Bourdin, firstly considering the technical themes within his work. The article will then progress to reflect on gender and the fetish elements in the photography by thinking through Judith Butler’s theory of performativity. Elaborating on the concept of the fetish, I will then discuss modernity and analyse Bourdin’s images as a product of, and comment on modernity applying Walter Benjamin’s ideas on fashion to open wider considerations of Guy Bourdin within the disciplines of fashion, photography and beyond.
Media policy analysis and diplomatic interactions during COVID-19 between China and the United States in a comparative perspective
Authors: Lu Fangzhu , Li Biao
Published: June 2021

This is a comparative study of official diplomatic speeches regarding COVID-19, released by spokespersons for the Ministry of Foreign Affairs of the People’s Republic of China (PRC) and documents from the United States Department of State China Archive. It explores how these speeches and documents reflect the US–China relations and the conduct of policies surrounding digital media in the two countries. We focus on the period from the start of the Wuhan lockdown, 20 January 2020, to the city’s reopening on 8 April, and use several forms of content analysis to analyse the documents: Latent Dirichlet Allocation (LDA) topic modelling, sentiment network analysis and word clouds. We argue that the diplomatic relationship and political ideologies adopted by different political and media systems can have a major impact upon media policy implementation and guidance.

Le Rayon vert de Jules Verne. La confrontation ironique des discours météorologiques
Authors: Becker Karin
Published: June 2021

Jules Verne’s Le Rayon vert (1882) is at the same time a scientific novel and a love story, a repertory of knowledge and a criticism of clichés. Telling the amusing attempts of a little group of travelers that tries in vain to catch sight of the “green ray” – the last impression of sunset – on the horizon from the Scottish coast, the author confronts in an ironical way different stereotypical discourses about weather phenomena which coexist in the bourgeois society of the late 19th century. Verne mocks equally scientific, folkloristic and romantic ideas about meteorological observations and uses these opposite explications of the mysteries of nature to characterize his protagonists and to develop the suspense of the narration.
A Middle Assyrian Fragment Mentioning Iron from Kassite Nippur
Authors: Ridder Jacob Jan de , Sassmannshausen Leonhard
Published: June 2021

In this study, a fragment from the Hilprecht Collection in Jena will be discussed. The tablet was previously identified as Middle Babylonian and published as TMH NF 5, 59. Closer inspection reveals Middle Assyrian palaeography. The fragmentary tablet deals with metals used for precious objects and was part of a larger inventory or letter. Noteworthy is a reference to iron, a metal rarely attested in Kassite Nippur but better known from the archaeological material and philological evidence from the Middle Assyrian Empire. An overview of philological evidence for iron in 2ndmillennium Assyria will be given in this study.
Promoting positive emotions among university EFL learners
Authors: Reilly Peter
Published: June 2021

Research indicates that investigation into the role of emotions during the process of second language acquisition (SLA) has lagged behind the work of educational psychologists. Experts in the area of achievement emotions have suggested that SLA researchers have limited their examination mostly to the role of anxiety and enjoyment. Consequently, an action research project was carried out, first, to determine whether emotions in addition to anxiety and enjoyment tend to arise when learning a second language (L2). Second, 13 advanced English as a foreign language (EFL) learners at a university in Mexico participated in 4 tasks as part of their class over the first 9 weeks of the semester, and subsequently were interviewed about their emotional experience. The tasks included a 45-s mindfulness activity, a reflection designed to promote a growth mindset, a discussion of a famous bilingual individual, and free voluntary reading. The findings revealed that a variety of achievement emotions emerged during the course, and in particular, in response to the learning tasks. It was concluded that not only can SLA researchers benefit from the strides made in psychology regarding emotions, but also that L2 educators should help L2 students experience pleasant achievement emotions by including activities of the sort described in this study.

Authors: Dai Hailong , Shi Shouwen , Yang Lin , Guo Can , Chen Xu
Published: June 2021

Hydrofluoric acid (HF) or fluoride ion corrosion issues are often encountered in many fields, which have attracted extensive research due to its strong corrosiveness. In this paper, a critical review is presented based on recent progress on HF corrosion. In view of the discrepancy of fluoride ion compared with other ions, the special attack characteristics of fluoride ion are firstly discussed. Afterwards, the corrosion mechanisms of stainless steels, nickel-based alloys, and titanium alloys in HF solution or fluoride ion-containing environment are reviewed, and three typical corrosion behaviors are summarized, which are essentially weakening process of passivation of metallic materials. The effects of influencing factors (e.g. alloying elements, environmental factors, and stress, etc.) on HF corrosion are also discussed, which involve changes in passivation mechanism, the influence of HF attack mode and multiple damage mechanisms due to mechanical–chemical coupling. Finally, future research works on HF corrosion are proposed.

Authors: Lotfi Saeedeh , Roshani Saeed , Roshani Sobhan , Shirzadian Gilan Maryam
Published: June 2021

This paper presents a new Doherty power amplifier (DPA) with harmonics suppression. A Wilkinson power divider (WPD) with open-ended and short-ended stubs is designed to suppress unwanted signals. To design the power divider in the circuit of the DPA, even and odd mode analyses are utilized. The proposed design operates at range of 1.2–1.6 GHz. The linearity of the suggested DPA is increased about 6 dBm, in comparison with the main amplifier. The designed Doherty amplifier has a power added efficiency (PAE), drain efficiency (DE) and Gain about 60, 61% and 19 dB, respectively. The designed WPD suppresses 2nd up to 14th harmonics with more than 20 dB suppression level, which is useful for suppressing unwanted harmonics in DPA design. ATF-34143 transistors (pHEMT technology) are used for this DPA amplifier design. The main amplifier has class-F topology and class-F inverse topology is used for auxiliary amplifier.
Liberating Hope in the Context of Pediatric Care at the End of Life
Authors: Champagne Elaine
Published: June 2021

The spiritual care of dying children and their families requires both sensitivity and competence. Parents – and adults, in general – not only recognize an intrinsic value in children, but also see them as important symbols of hope and as promise for the future. Hence, hope may be challenged when a child is facing death. From the field of spiritual and practical theology, this research attempts to correlate the experience of children and families, and Christian sources on hope. Particular attention is given to the importance of bodies and space, desires and fears, as well as to the role of narratives in order to deepen the meaning of hope in situations that seem bereft of it.
Moving Beyond the Clerical Paradigm: Practical Theology in the Korean Context
Authors: Kim Hyun-Sook
Published: June 2021

Over the past few decades, practical theologians in Korea have devised a framework to address important issues, correlating theory and practice and bridging the divide between pastors and lay people to facilitate open communication. However, the clerical paradigm has deep roots in Korean culture and ideology, which, combined with the Confucian patriarchal system, poses a challenge to Korean practical theology. These factors cause practical theology to reflect on its limitations and to move toward a hermeneutical-praxis paradigm by dealing with Christian praxis, connecting church with society for public responsibility, and providing an egalitarian leadership between pastors and lay people.

Proto-Slavic *ū-stems and the Polabian language
Authors: Janczulewicz Paweł
Published: June 2021

The paper deals with the issues (both inflectional and word-formational) of Proto-Slavic *ū-stems in the Polabian corpus. The aim of the paper is to identify all Polabian words continuing the *ū-declension class and accompany them with comprehensive linguistic and, when necessary, philological comments. As it turns out, some words, regarded as Polabian innovations, are in fact archaisms, as evidenced by comparative data. A new explanation of heteroclitic stems (Nsg -o vs. NApl -våi̯) is proposed involving a well-known Polabian sound change (*Kvo > Ko), which is somewhat elaborated.
Uzbekistan – A Region of World Society? Variants of Differentiation in Agricultural Resources Governance
Authors: Hornidge Anna-Katharina , Van Assche Kristof , Shtaltovna Anastasiya
Published: June 2021

This article studies the layered coexistence and mutual shaping of three forms of differentiation (functional, segmentary, hierarchical) in rural Uzbekistan, a region of world society that, since 1991, is undergoing tremendous processes of socio-economic transformation and change. More precisely, we analyse the evolving governance of land, water and agricultural support services (knowledge & advice) in the Uzbek province of Khorezm, where currently three types of farms utilise various social practices to navigate a complex and partly opaque environment marked by various forms of differentiation, each posing different opportunities, threats and coordination mechanisms (institutions). In doing so, the article builds on Rudolf Stichweh’s considerations of world society’s structural patterns, its ‘Eigenstructures’ as well as Niklas Luhmann’s conceptualisation of world society’s autopoietically closed function systems. Based on ethnographic research, we argue that the mobilisation of patron-client relationships, a complex system of coercive reciprocity and a trilogy of formal, strategic and discursive practices are widely employed to cope with the coexistence of an undermined layer of functional differentiation and reaffirmed/reinvented segmentary and hierarchical identities. We argue that the skilful navigation by local actors between these different differentiation forms and their demands, embodies a short-term adaptation strategy that is likely to hamper a (re-)crystallisation of autonomous functional domains. Hampering functional differentiation jeopardises long-term change adaptation.
Regional Variationsofand Regional VariationswithinFunctional Differentiation – The Middle East and World Society
Authors: Albert Mathias , Stetter Stephan
Published: June 2021

This article highlights the territorial and functional embedding of world regions within a functionally differentiated world society, as well as the heterogeneity between different (local) practices of functional differentiation within world regions. Its argument proceeds in two steps. In a first step, it discusses the distinction between regional variationsoffunctional differentiation versus regional variationswithinfunctional differentiation as an important tool in order to characterize specific variations of structural patterns. In a second step it turns to the Middle Eastern case, arguing that while at first glance this may be a candidate for a regional variation of functional differentiation, a closer look reveals that it has been characterized by a very specific variationwithinfunctional differentiation for quite a while. The article concludes by using these observations for some thoughts on the functional differentiation of world society more generally.

Częściowa resekcja pęcherzyka żółciowego (SC) to metoda leczenia stosowana w przypadku tzw. trudnej cholecystektomii. Pozwala minimalizować ryzyko uszkodzenia dróg żółciowych, w przypadku gdy z powodu dużego nacieku zapalnego niemożliwe jest bezpieczne wypreparowanie struktur w obrębie trójkąta Calota. SC jest jednak metodą obarczoną większym ryzykiem przecieku żółci, pozostawienia kamienia w kikucie pęcherzyka lub przesunięcia złogów do światła przewodu żółciowego wspólnego (PŻW) w porównaniu do całkowitej cholecystektomii. W pracy zaprezentowano przypadek 53-letniego mężczyzny, u którego wykonano SC z powodu znacznego nacieku zapalnego w okolicy kieszonki Hartmanna w przebiegu ostrego zapalenia pęcherzyka żółciowego. W przebiegu pooperacyjnym – z uwagi na przeciek żółci – wykonano ECPW z protezowaniem dróg żółciowych, a następnie pacjenta reoperowano, wycinając zapalnie zmieniony kikut pęcherzyka z zalegającym złogiem. Z powodu infekcji w ranie pooperacyjnej, z górnego i dolnego bieguna rany usunięto szwy i pozostawiono do gojenia przez ziarninowanie. Dzięki pozostawieniu szwów w centralnej części rany uzyskany efekt kosmetyczny gojenia jest zadowalający.

The work was aimed at studying the effects of combining epoxidized soybean oil (ESO) with standard bisphenol type A epoxy resin (ED-20). The ED-20 / ESO ratios were 100/0, 90/10, 95/15 and 80/20 (wt%). The system was cured with amine hardener mono(cyanethyl) diethylenetriamine (MCDT), triethanolamine (TEA) and mixture thereof (TEA + MCDT) at different curing temperatures. The choice was based on the hardener’s ability to open oxirane cycles, form a spatial network and initiate several parallel reactions. The viscoelastic properties, mechanical properties (tensile strength and elongation) were studied the density of obtained ED-20 / ESO samples was determined. The results showed that the introduction of ESO into epoxy resin ED-20 was accompanied by significant changes in the curing and final properties of the samples. It was shown that the physic- mechanical properties of polymer compositions ED-20 / ESO were determined by both the ESO content and the temperature of curing Depending on the selected curing mode, the addition of 5–10 wt.% of ESO increased the tensile strength relative to the σр value of the original epoxy matrix. The values of relative elongation increased significantly at 15-20 wt.% of ESO. By the method of dynamic mechanical analysis it was shown that the increase of ESO content leads to plasticization of epoxy composition and to reduction of crosslinking density. It was determined that 5-10 wt.% was the optimal concentration of ESO, at which the epoxy composition had improved physical and mechanical properties Further increase of ESO content reduced the crosslinking density and increased the defectiveness of the epoxy polymer, which causes premature failure in weak places of the structure under load.

The development and investigation of photopolymerization composite (PhPC) materials with improved photochemical and physical-mechanical properties, providing the possibility of using them during image formation processes in 3D printing technologies, have been carried out. The effect of the nature and amount the polymerization composition constituents on the photocuring of urethane methacrylate and etheracrylate oligomers with the inclusion of organosilicon modifiers, as well as tertiary aminemethacrylates in the process of their irradiation with LED lamps of different wavelengths in the presence of photoinitiators, has been investigated. The effect of the nature and amount of photoinitiators on the optical and polymerization properties of materials and coatings was studied using a PLAZMON-71 spectrometer. According to the results of the calculated photopolymerization kinetic parameters (rate, induction period), it was found that the composition containing the photoinitiators Irgacure 819 (2%), Darocur 1173 (1%), as well as tertiary aminemethacrylate (5%) provides a high polymerization rate and a slight induction period among the investigated compositions. The surface plasmon resonance method allows to determine and control the rate of composite materials photocuring during forming images in 3D printing technology. The possibility of regulating the photochemical and operational characteristics of the constructed nanocomposite materials with the inclusion of organosilicon modifiers in the composition according to their purpose in technological processes of stereolithographic recording of 3D information during printing volumetric images is demonstrated.

Published: June 2021

Sin importar el tipo de tecnología aplicada para la secuenciación de un genoma, el filtrado de secuencias es un paso esencial, en el cual aquellas lecturas de baja calidad o parte de estas son eliminadas. En un ensamblado la construcción de un genoma se realiza a partir de la unión de lecturas cortas en cóntigos. Algunos ensambladores miden la relación que existe entre secuencias de una longitud fija (k-mer) que puede verse afectada por la presencia de secuencias de baja calidad. Un enfoque común para evaluar los ensamblados se basa en el análisis del número de cóntigos, la longitud del cóntigo más largo y el valor de N50, definido como la longitud del cóntigo que representa el 50 % de la longitud del conjunto. En este contexto, el presente estudio tuvo como objetivo evaluar el efecto del uso de lecturas crudas y filtradas en los valores de los parámetros de calidad obtenidos en el ensamblado del genoma de la cepa de Bacillus altitudinis19RS3 aislada de Ilex paraguariensis. Se realizó el análisis de calidad de ambos archivos de partida con el softwareFastqC y se filtraron las lecturas con el softwareTrimmomatic. Para el ensamblado se utilizó el softwareSPAdes y para su evaluación la herramienta QUAST. El mejor ensamblado para B. altitudinis19RS3 se obtuvo a partir de las lecturasfiltradas con el valor dek-mer 79, que generó 16 cóntigos mayores a 500 pb con un N50 de 931 914 pb y el cóntigo más largo de 966 271 pb.
Dynamic monitoring algorithm of natural resources in scenic spots based on MODIS Remote Sensing technology
Authors: Li Maolin
Published: June 2021

A dynamic monitoring algorithm of natural resources in scenic spots based on MODIS remote sensing technology is proposed to improve natural resources monitoring accuracy in scenic spots. The remote sensing images of scenic spots obtained by MODIS were preprocessed by TM image processing, atmospheric correction, and other technologies to get high-precision remote sensing images. The remote sensing images of scenic spots were segmented by the multi-scale segmentation method, and then the hierarchical supervision classification method was used. The change points of natural resources were extracted. The resource changes and independent variables of scenic spots were analyzed based on the least square method to realize the dynamic monitoring of natural resources in scenic locations. The experimental results show that the technique can accurately monitor the dynamic changes of forest resources and water resources in scenic spots, and the monitoring results have high accuracy.
Application of remote sensing technology in the analysis of periodic precipitation change in China’s Northern semi-arid area
Authors: Zhang Yannan , Liang Chuan
Published: June 2021

The remote sensing technology is used to analyze the periodic changes of precipitation in the semi-arid areas of northern China and provide a reference basis for precipitation prediction. Authors were based on GPS observation data and corresponding ground meteorological parameters to obtain the study area’s comprehensive water vapor content value and use precipitation and time to establish a linear regression equation based on the content value to express the precipitation trend change. The periodic structure and abnormal changes of the periodic precipitation series on different time scales were obtained through wavelet analysis, combined with anomaly calculations to analyze the increase and decrease precipitation characteristics. The Morlet continuous wavelet transform map was also used to reflect the periodic oscillations of precipitation on different time scales. The wavelet variance map was used to reflect the distribution of regional precipitation with scale years. The authors analyzed the cycle change characteristics of the comprehensive precipitation series in Harbin, Changchun, Shenyang, and Dalian. They concluded that the annual precipitation in the four regions showed a decreasing trend in 50 years. And through the wavelet cycle frequency-domain relationship change law, the change characteristics of precipitation in the northern semi-arid area in the entire time domain were obtained.

Published: June 2021

This research was conducted on a farm of Payam-e-Noor University in Piranshahr, in West Azerbaijan province of Iran, during 2014-2015 and 2015-2016 crop sessions to investigate the wheat physiological traits response to standard and ecological agricultural systems. The experiment was conducted as a split-plot design with two factors and three replications. The first factor, which was considered the main plot, included high, low-input, and ecological agricultural systems. Subplots were seed pre-treatment, including control (without priming), hydro priming, and food priming with ascorbate. The results showed that the least photosynthesis rate and mesophilic conductance were related to low-input agricultural system; however, in the ecological system, the transpiration, substomatal carbon dioxide, and water use efficiency of photosynthesis were the lowest. Also, seed priming increased the photosynthesis rate, mesophilic conductivity, and water use efficiency of photosynthesis.
FORMALIZATION OF REGULATORY TEXTS
Authors: Пименов Виктор , Voronov Mihail
Published: June 2021

Modern information technologies provide text manipulation processes with high efficiency. First of all, this means storing, editing, and formatting texts and their components. Having achieved significant success in developing tools for content-free computer text processing, researchers faced problems with their content processing. Therefore, further steps in this direction are associated with the creation, among other things, of methods for automated purposeful manipulation of texts, taking into account their content. The analysis of works devoted to the study of the problems of formal presentation of texts and their subsequent use is carried out. Despite a number of successful projects, the challenges of solving the problem of the relationship between the content of the text and its meaning remain relevant. It seems that formalization of a General-purpose text while preserving its semantics is not feasible at this stage. However, there are types of texts that can be formalized while preserving their semantics. One of them is a regulatory text type, which is essentially a verbally expressed algorithm for a sequence of targeted actions. It is distinguished by logic and accuracy (lack of allegories), coherence and integrity, clarity, understandability (due to the lack of emotional coloring and figurative means), accessibility (due to the use of specific terminology). In other words, when developing regulatory texts, they usually try to display the mechanisms of the described actions as clearly as possible. Purpose: development of a method for formalizing a regulatory text while preserving its semantics. Methods: structural linguistics, representation of objects in the form of an ontology, constructive algorithms. The use of this method is demonstrated by describing the solution of a system of algebraic equations. Results: method for constructing a mathematical model of a regulatory text. Practical relevance: the application of the developed method makes it possible to develop software systems for building libraries of individual subject areas, develop tools for evaluating regulatory texts for their certainty, completeness, connectivity and other characteristics, as well as simulators and self-learning tools.

Published: June 2021

The pulse profiles of the radiation coming from X-ray pulsars with an accretion column were modeled. Gravitational lensing and redshift in the Schwarzschild metric, as well as the reflection of X-Ray photons from the surface of a neutron star, were taken into account. On the basis of the obtained pulse profiles an analysis of possible errors in the measurements of the luminosities of X-ray pulsars associated with the inability of the observer to correctly take into account the anisotropy in the radiation emerging from the neutron star, as well as the angles between the pulsar’s rotation axis, the magnetic axis and the line of sight, was carried out.

Authors:   Ural Federal University, Permyakova T. A. , Loktin A. V. ,   Ural Federal University
Published: June 2021

In this study were discussed the LAMOST catalog opportunities in the statistical studies of the spectra of stars in open star clusters (OSC). We considered the Pleiades and Praesepe clusters. We examined the absolute stellar magnitude — metallicity relationships for the members of these clusters. Contrary to expectations, a noticeable dependence of the metallicity on the absolute magnitude of the stars in the main sequences of the studied clusters was found, which may be associated with systematic errors in measuring the metallicities for visually faint stars.

The paper presents the results of observations of the Uranian and Neptunian satellites performed in 2020 with the 1-meter mirror telescope ‘Saturn’ (Pulkovo observatory) and the 350-mm guide telescope of the ‘Sintez’ telescope (Crimean observatory). More than 8 thousand separate positions of the satellites were obtained in the Gaia EDR3 catalog system. The average values of standard errors of the satellite normal place in right ascension and declination for the entire observation period, demonstrating the internal convergence of the observation results, lie within 10—50 mas.

Authors:   Astronomical Observatory of the Ural Federal University, Ladeyschikov D. A.
Published: June 2021

The first results of developing a database of water masers in star-forming regions are presented. The database is stored online at the address http://maserdb.net. The coverage of the database at the time of publication is 84 % of all positive detections of water masers in star-forming regions from the available literature. Preliminary statistical analysis of the data and study of the association between water masers and ATLASGAL 870 μm sources was carried out. A relation was obtained from the generalized linear model to estimate water maser detection probability depending on the physical parameters of clumps from the ATLASGAL catalogue. According to estimates, only ∼25 % of the total number of water masers towards ATLASGAL sources has been detected at the moment.
Dynamical evolution of asteroid pairs in the vicinity of resonances

Published: June 2021

Dynamical evolution of asteroid pairs in close orbits near Jovian mean motion resonances (3 : 1, 4 : 1, 5 : 2, 7 : 3) has been researched by means of numerical integrations of the equations of motion over 1 Myr time interval in the future. Initial orbital elements’ uncertainty and semi-major axis drift due to the Yarkovsky effect significantly affect orbit modification with time, especially for objects originally situated in the vicinity of resonances. Passing through a resonance generally leads to orbital distance growth.

Published: June 2021

Studying the formation of massive stars in our Galaxy and in other galaxies is one of the possibilities to connect the information obtained for the regions of star formation in general. This study presents statistical and theoretical data on infrared ring nebulae (IRRN) in our Galaxy and the galaxy M33, which is located not far from us and in the plane of sky, which is convenient for selecting individual objects. In this paper, comparisons of fluxes for 258 star-forming complexes in M33, extragalactic of star formation complexes, and for IRRN in our Galaxy are shown. A theoretical calculation of the distribution of polycyclic aromatic hydrocarbons using DustEM has been carried out.

Published: June 2021

To detect inhomogeneities in the thermal radiation of exoplanet HD209458b, based on observations of the Spitzer space telescope processing and modeling of the light curves of secondary transits (eclipses) were carried out. Current work is the basis for the mapping of the temperature distribution on the dayside of the exoplanet. Tidal and electromagnetic star-planet interactions, together with climate effects, lead to nonuniform heating of the surface. We obtained that the depth of the eclipse was 0.101±0.009% of the total flux of the system and is consistent with the results of other works.
Formação para o SUS: a trajetória de adesão de um curso de terapia ocupacional às políticas indutoras de mudança curricular Pró e PET-Saúde,

Resumo Tendo por base a relevância das políticas indutoras da formação para, com e no Sistema Único de Saúde (SUS), este artigo apresenta a experiência da participação do Curso de Graduação em Terapia Ocupacional da Universidade Federal do Rio de Janeiro no Pró-Saúde e no PET-Saúde, bem como indica as perspectivas e desafios que ainda se configuram. Trata-se de um relato de experiência a respeito de como, juntamente com outros cursos da universidade, o curso de terapia ocupacional se lançou ao desafio de rever sua matriz curricular, criando metodologias de ensino e aprendizagem que favorecessem uma formação profissional eticamente compromissada com o SUS e que reconhecessem o papel estratégico da Atenção Básica à Saúde (ABS) nos modos de pensar e agir em saúde. Nesse contexto, foi eleita uma unidade básica de saúde no entorno da Universidade que passou a receber estudantes de seis disciplinas obrigatórias remodeladas para promover maior integração ensino-serviço. Também foram desenvolvidas ações de extensão e projetos de pesquisa abarcando populações historicamente atendidas pela terapia ocupacional, mas com acesso limitado à ABS. Por fim, foi criada uma disciplina obrigatória sobre o tema. As iniciativas do curso de terapia ocupacional se configuraram como resistência a processos de captura dos modos de produção do cuidado pela lógica produtivista, insistindo na sensibilização dos atores, na visibilidade a seus modos de saber-fazer alinhados à perspectiva da integralidade, e na articulação da construção de terrenos férteis para a produção de saúde e convivência com e nas diferenças.
POR UM HORIZONTE PÚBLICO NA EDUCAÇÃO DAS CRIANÇAS
Authors: Araújo Vania Carvalho de
Published: June 2021

Este artigo propõe discorrer sobre a extensão da crise do mundo moderno no âmbito da educação ressaltada por Hannah Arendt em seu ensaio “A crise na educação”. O questionamento sobre “a obrigação que a existência de crianças impõe a toda a sociedade” é a chave de leitura para uma aposta ético-política na formação das novas gerações em um mundo desencantado pela estranheza do humano e pela flagrante negação de critérios que o passado – como autoridade – nos legou como apoio para a ação e julgamento sobre o mundo. Se à educação não deve recair toda a responsabilidade pelo mundo, ao menos deve ser capaz de inserir as crianças em uma cultura pública que as possibilitem voltar para o aspecto público do mundo para dele se apropriarem. As questões tematizadas por Arendt nos mobilizam a pensar que somente uma educação fundada em um horizonte público é capaz de formar as crianças de modo que tenham a oportunidade, quando jovens, de agir no mundo e serem capazes de discernir o justo do injusto, a verdade da mentira, o bem do mal. Se suas reflexões revelam a utopia de seu pensamento, revelam também a esperança e a responsabilidade coletiva que a chegada das crianças em um mundo preexistente nos impõe.

Defoliation and dieback of Sitka spruce in Reykjavík, Iceland

Published: June 2021

The green spruce aphid Elatobium abietinum is an important defoliating pest of Sitka spruce (Picea sitchensis) in Iceland. A comparison of two urban Sitka stands in Reykjavík, from 2013-2017, reveals a distinct defoliation difference between trees located near a main road (94% defoliated) and several hundred meters away from heavy traffic (47%). Chemical analyses of the spruce needles demonstrate substantially higher nitrogen ratios in trees near traffic. Furthermore, the recently warming winter temperatures promoted larger overwintering aphid populations since 2003, as well as a shift of mass outbreaks from autumn to spring, accompanied by distinct growth suppressions one year after an aphid population spike in the post-2003 tree-ring data. The results of this study indicate that the mechanisms triggering Sitka spruce dieback in Reykjavík include a combination of increasing winter temperatures, more frequent and severe green spruce aphid outbreaks, as well as elevated N values in the needles of urban trees.
