Authors: Siciliano Giulia , Yu Yue , Fottner Johannes
Published: August 2022

This article considers two dynamic hybrid pallet warehouses obtained hybridizing a shuttle-based warehouse with stacker cranes. We begin by describing their design and characteristics. Afterwards, we explain the control algorithms that were developed for them. Next, we illustrate the modalities of the discrete event simulation study we ran to investigate their performance. In conclusion, we discuss the results in terms of throughput of the simulation study to individuate the field of application for the two layouts of dynamic hybrid pallet warehouses in comparison to stacker crane-based and shuttle-based warehouses.

Published: August 2022

Finding the optimal distribution of exerted effort by an athlete in competitive sports has been widely investigated in the fields of sport science, applied mathematics and optimal control. In this article, we propose a reinforcement learning-based solution to the optimal control problem in the running race application. Well-known mathematical model of Keller is used for numerically simulating the dynamics in runner's energy storage and motion. A feed-forward neural network is employed as the probabilistic controller model in continuous action space which transforms the current state (position, velocity and available energy) of the runner to the predicted optimal propulsive force that the runner should apply in the next time step. A logarithmic barrier reward function is designed to evaluate performance of simulated races as a continuous smooth function of runner's position and time. The neural network parameters, then, are identified by maximizing the expected reward using on-policy actor-critic policy-gradient RL algorithm. We trained the controller model for three race lengths: 400, 1500 and 10000 meters and found the force and velocity profiles that produce a near-optimal solution for the runner's problem. Results conform with Keller's theoretical findings with relative percent error of 0.59% and are comparable to real world records with relative percent error of 2.38%, while the same error for Keller's findings is 2.82%.
A Model for Predicting the Amount of Photosynthetically Available Radiation from BGC-ARGO Float Observations in the Water Column
Authors: Stahl Frederic , Nolle Lars , Zielinski Oliver , Jemai Ahlem
Published: August 2022

Modern oceanography uses, amongst other platforms, automated diving devices, which are drifting with the ocean current whilst continuously collecting vertical profiles of environmental parameters. One of the important parameters is photosynthetically available radiation (PAR). It was studied in this work whether the PAR values can be reconstructed by combinations of measurements from the remaining onboard sensors with specific wavelength. If a reconstruction of PAR is possible, this would allow allocating the sensor with a further specific wavelength instead of PAR. Having available more spectral information could for example enable natural science researchers to better distinguish phytoplankton or UV radiation. Therefore, data from three different expeditions from different regions of the world were used to model PAR using multiple linear regression and regression trees (RT). multiple linear regression achieved an R2 value of 0.970 for the combined dataset and RT achieved an R2 value of 0.960. Hence, the models are accurate enough to predict the PAR parameter without the need for a dedicated PAR sensor. Thus the PAR sensor could be allocated instead with a further specific wavelength.
FEM study on the strength increasing effect of nitrided spur gears
Authors: Molnar Jakab , Zwierczyk Peter T. , Csoban Attila
Published: August 2022

In this research, the strength increasing effect of nitriding was investigated on a small series of spur gears with a module of 1 mm. The nitriding process was simulated in ANSYS FEM software with DANTE heat treatment external add-on. Only a simplified transient heat treatment model was created to study the basics and the effects of nitriding on spur gears. As a result, the nitrogen distributions, the hardness of the gear tooth flanks, the residual stresses and deformations were calculated with DANTE. Approximate surface endurance limit could be calculated analytically for the analysed spur gears according to the local endurance limit formula of Kloos and Velten. As the surface endurance limit value increased because of the nitriding process, the calculated allowable torque of the driving gear also increased. Even though the higher allowable torque and the initial residual stress increased the contact stress of the gear pairs, the calculated contact stress remains acceptable.
On the Use of Graphical Digital Twins for Urban Planning of Mobility Projects: a Case Study from a new District in Ålesund, Norway
Authors: Major Pierre , da Silva Torres Ricardo , Amundsen Andreas , Stadsnes Pernille , Mikalsen Egil Tennfjord
Published: August 2022

Urban planning is a complex task often involving many stakeholders of varying levels of knowledge and expertise over periods stretching years. Many urban planning tools currently exist, especially for mobility planning. However, the use of such tools often relies on ad-hoc modelling of "expensive" domain experts, which hampers to incorporate new knowledge and insights into the planning process over time. Another issue refers to the lack of interactivity, i.e., stakeholders can not easily change configurations of simulations and visualize the impact of those changes. This paper presents and discusses the benefits of using a graphical digital twin to overcome such shortcomings. We demonstrate how a digital-twin-based approach improves the current planning practices from two perspectives. The first refers to automating the configuration and data integration in models, making the tool flexible and scalable to large-scale planning involving multiple cities on a national level and supporting automatic updates of employed models when input data is updated. The second refers to supporting interaction with the model through a user interface that allows stakeholders to perform actions, leading to insightful what-if scenarios and therefore better-informed decisions. We demonstrate the effectiveness of using graphical digital twins in a compelling real usage case study concerning urban mobility planning in Ålesund, Norway. Finally, this paper also outlines recommendations and further research opportunities in the area.
Learned Parameterized Convolutonal Approximation of Image Filters
Authors: Chaganova Olga , Grigoryev Anton
Published: August 2022

Multilayer neural networks are considered universal
approximators applicable to a wide range of problems. There are quite detailed theoretical and applied studies for fully connected networks, while for convolutional networks the results are more scarce. In this paper, we tested the approximating capability of deep neural networks with typical architectures like ConvNet, ResNet, and UNet as applied to classical image processing algorithms. Canny edge detector and grayscale morphological dilation with the disk structuring element were selected as target algorithms. As we have seen, even relatively lightweight neural models are able to approximate a filter with fixed parameters. Since classical algorithms are parameterized, we considered different approaches to the parameterization of the neural networks and found out that even the simplest of them, adding parameters in the input images channels, works well for low parameter count. Also, we measured an inference time of a neural network approximation and a classical implementation of the grayscale dilation with the disk structuring element. Starting from a certain radius, a neural network works faster than an algorithm even on one core of the CPU without fine-tuning the architecture for performance, thus confirming the viability of ConvNets as a differentiable approximation technique for optimization of classical-based methods.
Formal Verification of Neural Networks: a Case Study about Adaptive Cruise Control
Authors: Demarchi Stefano , Guidotti Dario , Pitto Andrea , Tacchella Armando
Published: August 2022

Formal verification of neural networks is a promising technique to improve their dependability for safety critical applications. Autonomous driving is one such application where the controllers supervising different functions in a car should undergo a rigorous certification process. In this paper we present an example about learning and verification of an adaptive cruise control function on an autonomous car. We detail the learning process as well as the attempts to verify various safety properties using the tool NeVer2 a new framework that integrates learning and verification in a single easy-to-use package intended for practictioners rather than experts in formal methods and/or machine learning.
Effect of impurities on stability of the skyrmion phase in a frustrated Heisenberg antiferromagnet
Authors: Mohylna Mariia , Zukovic Milan
Published: August 2022

We employ a hybrid Monte Carlo simulation implemented on GPU to study the effect of nonmagnetic impurities in a frustrated Heisenberg antiferromagnetic (AFM) model on a triangular lattice with Dzyaloshinskii-Moriya interaction in the presence of the external magnetic field. We focus on the skyrmion lattice phase (SkX), which in the pure model is known to be stabilized in a quite wide temperature-field window. We aim to confront the effect of impurities on the SkX phase in the present frustrated AFM model with that in the nonfrustrated ferromagnetic counterpart as well as to consider more realistic conditions in the proposed experimental realizations of the present model. We show, that up to a fairly large concentration of the impurities, p ~35%, the SkX phase can survive albeit in somewhat distorted form. Distortion of the SkX phase due to formation of bimerons, reported in the ferromagnetic model, was not observed in the present case.
Massive Degeneracy and Anomalous Thermodynamics in a Highly Frustrated Ising Model on Honeycomb Lattice
Authors: Zukovic Milan
Published: August 2022

We numerically study a prototypical frustrated Ising model on a honeycomb lattice with competing nearest- and second-nearest-neighbor antiferromagnetic interactions, J1 and J2, for the highly frustrated case of J1= J2. We employ both standard (SMC) and a more sophisticated replica exchange (REMC) Monte Carlo simulations in effort to demonstrate the difficulties of using the former and advantages of using the latter approaches. The ground state of the system is highly degenerate and consists of frozen superantiferromagnetic (SAF) domains, separated by zero-energy domain walls (ZEDW), thus showing no conventional long-range ordering. We demonstrate that such states are difficult to access by using SMC due to complex multimodal energy landscape, characteristic for such systems. On the other hand, the REMC approach turns out to be more efficient in exploring it and thus reaching also states not accessible to SMC. At finite temperatures, the system shows a peculiar behavior with multiple anomalies in thermodynamic functions, which can be attributed to the transitions between several states with the SAF-like ordering characterized by different types of ZEDW.
Politik Lama Versus Politik Baharu: Dinamika Politik Melayu dalam Pilihan Raya Negeri Johor 2022
Authors:   Pusat Bahasa dan Pengajian Asasi Universiti Sultan Azlan Shah Bukit Chandan, 33000 Kuala Kangsar, Perak, Malaysia, Shah Mohd Akmal Abdul Halim
Published: August 2022

Pilihan Raya Negeri (PRN) Johor yang diadakan pada 12 Mac 2022 merupakan siri pilihan raya negeri yang keempat diadakan selepas PRN Sabah, Melaka dan Sarawak sejak berlangsungnya Pilihan Raya Umum ke-14 (PRU-14) pada 2018. Bagi negeri Johor, PRN 2022 menunjukkan perkembangan menarik dalam politik orang Melayu. Sebelum ini, neofeudalisme telah menjadi identiti politik negeri sejak sekian lama berdasarkan pertautan historikal-nilai sentimental antara negeri ini dengan parti UMNO. Nilai sentimental tersebut membolehkan UMNO-BN membentuk hegemoni politik Melayu dalam tempoh yang panjang sehingga negeri ini turut dilabel sebagai kawasan ‘simpanan tetap’ UMNO. Bagaimanapun, faktor semasa yang melatari PRN Johor 2022 kali ini – merangkumi dominasi isu ekonomi berpunca daripada COVID-19, dan krisis politik yang dihujahkan mengancam kestabilan politik – menjadi pemboleh ubah yang signifikan dalam menciptakan karaktor baharu bagi politik orang Melayu di Johor dan Malaysia pada umumnya. Kajian ini bertujuan menganalisis dinamika politik Melayu dalam PRN Johor 2022 melalui kesinambungan politik lama dengan politik baharu berdasarkan persaingan antara UMNO dengan parti Melayu alternatif seperti BERSATU/PN. Kajian ini menggunakan kaedah kualitatif (kajian kes) melalui data-data primer dan sekunder yang diperolehi daripada pemerhatian dan pengamatan umum dan di lapangan, temu bual, serta kajian kepustakaan. Hasil kajian menunjukkan kedinamikan dalam lokus politik Melayu telah ditonjolkan UMNO dan BERSATU melalui naratif politik baharu. Isu-isu progresif yang lebih sinonim dengan parti rentas-etnik Pakatan Harapan (PH) mula dibawakan oleh kedua-dua parti ini, seperti tadbir urus baik, pendemokrasian, integriti dan ketelusan. Begitu pun, kajian ini juga mendapati wujudnya naratif politik lama dalam kadar tertentu dengan hujahan demi mengimbangi segmen pengundi Melayu yang signifikan buat kedua-dua parti konservatif Melayu ini. Sepertimana biasa, elemen politik lama dalam bentuk naratif politik pembangunan dan neofeudal masih ditemukan. Kajian ini juga mendapati bahawa pertembungan UMNO dan BERSATU di kawasan majoriti Melayu menunjukkan wujudnya kedinamikan praktis politik lama yang dihujahkan mewujudkan ruang demokrasi kompetitif berbanding dominasi satu parti.
Beyond the Artifact: Unfolding Medieval, Algorithmic, and Unruly Lives of Maps
Authors: Wöll Stephen
Published: August 2022

Found on the walls of ancient caves in northern France, the earliest known maps do not depict the earth but the brightest stars of the milky way. Although we know little about the people who painted these maps, we know that they, like us, looked for answers and meaning. Mapping as material testimony of this desire signals a basic function of human placemaking. Discarding the biographical shallowness of cartography, this paper investigates how maps might assume social agency. Since spaces are (socially) constructed not only of sight but also of memories, affect, or tactile experiences, I investigate how maps enter spatiotemporal relationships and become agents of social critique by asking: When do maps exceed their role as material artifacts by interfacing with mental geographies of individuals or societal structures? Unfolding the social lives of maps, the paper proposes, demonstrates their ability to exceed traditionally assumed utilitarian roles as lifeless transmitters of ‘objective’ facts, instead revealing cartographic assemblages of identity, memory, trauma, and protest.
World Views: Cartographers, Artisanship and Epistemology in Early Modern Italy
Authors: Roberts Sean
Published: August 2022

Scholars have long since demonstrated that no such occupation as “cartographer” existed in early modern Europe. Instead, the skills needed to produce maps often combined those of manuscript illuminators, scribes, mathematicians, letterpress operators, and engravers - to name only a few. Though it is common to speak of maps as offering insight into “world views,” we often assume these to be those of patrons and viewers rather than of the craftspeople who produced them. These artisans relied upon a host of tools, skills, and materials which varied tremendously from city to city even within discrete geographic regions. Moreover, though many early modern maps were only marginally related to the practical activity of way-Dinding, those who labored to create them were often themselves itinerant artisans moving across the Alps and beyond. In this essay, I chart the training, experiences, and know-how of the engineers, printers, painters, and woodworkers who made maps. I explore the ways in which the trans-national and often multilingual social-lives of these makers informed the material fabric of their maps and, in turn, shed light upon the sometimes unexpected interpenetration of biography, world view, and object that characterizes cartographic cultures between the Difteenth and seventeenth centuries. My approach thus seeks to bridge recent insights on the “artisanal epistemology” of makers with a critical approach to the agency of objects, informed both by anthropological theory and a renewed focus on materiality which has come to characterize studies of visual culture.
The main interpretations of the concept of "imperialism" in the modern theory of international relations.
Authors: Veselov Yuriy Aleksandrovich
Published: August 2022

This article is built around the phenomenon of "imperialism" and represents an understanding of the role of the object under study in modern international relations. The aim of the work is a theoretical definition of the essence of imperialism as a phenomenon in world history and world politics. The author analyzed imperialism from the point of view of two of the three main paradigms of international relations – Marxism and political realism, and within the framework of the second mentioned paradigm tried to form a new concept of imperialism in the theory of international relations, which would be less ideologized, but an equal alternative to the Marxist view. It is noteworthy that the author deliberately did not use the works of pioneer researchers of the phenomenon under study and focused on more modern, relevant and less well-known works that already show the dynamics of the development of scientific research. The author comes to the conclusion that, from the point of view of two paradigms analyzed in detail, the modern world can be called imperialistic, and imperialism is inextricably linked with the system of international relations and the current world order. The main achievement of this work is the development of the author's concept of imperialism, created with respect and based on the research of non-Marxist predecessors. It should also be argued that some scenarios of the collapse of such an order can be perceived by Marxists as the collapse of imperialism, but for another paradigm only the final fall of all powers can mean its collapse. The author also admits that imperialism of the new world order will evolve to its new state, acquire new levers, forms, and will be characterized by a different set of methods.
Trust in Power among Modern Russian youth: the role of Values and ethnic identity
Authors: Fedotova Vera Aleksandrovna
Published: August 2022

Leading Russian and foreign scientists have repeatedly noted a decrease in public confidence in the government and most political institutions. The loss of citizens' trust in the government has also affected Russia. The purpose of the presented research is to study the phenomenon of political trust in the aspect of value orientations and ethnic identity among modern Russian youth. The study conducted diagnostics of the younger generation of Russians living in different regions of the Russian Federation, aged 18 to 34 years. The study sample included representatives of the cities of the Russian Federation: Perm, Yekaterinburg, Moscow, St. Petersburg, Nizhny Novgorod and rural areas. The following methods were used in the empirical study: the scale of political trust, the methodology of J. Finney, measuring the severity of ethnic identity and Schwartz's methodology for determining the value structure. The level of trust in the authorities is at a fairly low level, which indicates a tendency to social cynicism rather than political trust. The ethnicity of modern youth is also at a fairly low level. The results of the regression analysis demonstrated that ethnic identity has an impact on the overall level of trust in the authorities. Values such as "Reputation", "Universalism: tolerance" and "Benevolence: a sense of duty" have the strongest influence on trust in the authorities. The value of material goods negatively affects the formation of trust in the authorities. The scientific significance lies in the fact that for the first time the problem of the formation of political trust in the aspect of personal values and ethnic identity was studied.The practical significance lies in the fact that the results of this study can serve as a basis for the development of recommendations in the field of building political trust among Russian youth.
Images of nature in D. Ulzytuev's diaries
Authors: Khalkharova Larisa
Published: August 2022

The subject of the study is the natural images captured in the diaries of the classic Buryat literature of the twentieth century D. Ulzytuev. The object of the study is the work of D. Ulzytuev from the period of the 1950s-1970s. The author examines in detail the genre of the diary in the writer's work, revealing its features. The main attention is paid to the identification of natural images that occupy a significant place. In the diaries, numerous sketches about nature are included in the narrative of the daily course of life, which is presented as an objective environment, based on which reality and subjective nature, reflecting the inner world of the artist, are endowed with psychologism, that is, they perform various functions.   The diaries of D. Ulzytuev are two notebooks – the first one related to the period of the poet's studies in Moscow in 1957-1958, the second – 1969-1970. Descriptive, comparative and comparative methods are used in the work. The novelty of the work lies in the fact that D. Ulzytuev's diaries are a unique phenomenon in the poet's creative heritage, and they have not become the object of scientific research until now. Consequently, the disclosure of images of nature in the diary genre contributes to a deeper understanding of the creative individuality of the author.All this allows us to conclude that the natural images in D. Ulzytuev's diaries bear the stamp of individual perception, are a means of expressing his inner world.
Narrative strategy of "Red China" exhibitions:on the example of the exhibition celebrating the centenary of the founding of the communist party of China
Authors: Yu Wei
Published: August 2022

Exhibitions dedicated to the theme of "Red China" occupy an important place in the dissemination of "red" culture, the continuity of the "red" gene and the intensification of "red" education. They reflect the political agenda, have a distinct content and the uniqueness of the text material. Being an important element of the spread of "red" culture, exhibitions on the theme of "Red China" integrate elements of this culture into people's daily lives and play an active role in preserving and multiplying the "red" gene. In this article, the systematization and generalization of knowledge in the field of narrative strategy of exhibitions on the theme of "Red China" is carried out from the point of view of ontology, structure and narrative carrier, which at the present stage is important for building a strong socialist ideology. Exhibitions on the theme of "Red China" are an important way of materialization, visualization and dissemination of "red" culture, as well as an effective means of its popularization. The study found that the "Red" exhibitions should have a "revolutionary content", have a "political character", be "mutually recognized by the authorities and the people", take on the main responsibility for providing people with common access to material and spiritual culture. From the point of view of the communication function of the "red" exhibitions, they are an important means of organizing ideological and political education by the Communist Party of China, strengthening social harmony and promoting basic values.
SUS: o debate em torno da eficiência
Authors: Marinho Alexandre , Ocké-Reis Carlos Octávio
Published: August 2022

O volume debate o uso do termo "eficiência" para avaliar a gestão do Sistema Único de Saúde. A obra busca examinar a eficiência no SUS a partir do fato de que tal argumento é sistematicamente utilizado para defender a mercantilização do próprio sistema. Segundo os autores, que se dedicam aos estudos da disciplina da economia da saúde desde a década de 1990, isso acaba encobrindo um constante ataque à ampliação do acesso à saúde promovido pela reforma sanitária brasileira. Os economistas Alexandre Marinho e Carlos Octávio Ocké-Reis argumentam que a palavra eficiência acaba sendo, dessa forma, vulgarizada e servindo para enfraquecer as políticas públicas de saúde. Segundo eles, não há dúvidas sobre as possibilidades de aperfeiçoamentos na gestão do SUS, especialmente por meio da ampliação do financiamento de seus recursos humanos. No entanto, não basta ser eficiente se os resultados não são atingidos e, principalmente, se as necessidades de saúde da população não são atendidas.

Published: August 2022

Watermelon (Citrullus lanatus) is an economically important cucurbitaceous crop worldwide. The productivity of watermelon is affected by both biotic and abiotic stresses. Flooding has significant impacts on the growth of watermelons by causing oxygen deficiency and a loss of agricultural productivity. Currently, we used the triploid and diploid watermelon Zhengzhou No.3 to study the dynamics of metabolites in response to flooding stress. Quantification of metabolites was performed by UPLC-ESI-MS/MS at different time intervalsi.e., 0, 3, 5 and 7 days under flooding stress. We observed that the activities of oxidants were higher in the diploid watermelon, whereas the higher antioxidant activities in the triploid watermelon makes them more resistant to the flooding stress. We also observed that the root activity and the chlorophyll in the triploid watermelon plants were higher as compared to the diploid watermelon plants. Co-expression network analysis leads to the identification of twenty-four hub metabolites that might be the key metabolites linked to flooding tolerance. Resolving the underlying mechanisms for flooding tolerance and identification of key molecules serving as indicators for breeding criteria are necessary for developing flooding-resistant varieties.

Published: August 2022

Introduction: The Coronavirus Disease-2019 (COVID-19) pandemic has caused considerable panic and anguish among the world’s population, including India. So, besides physical health, COVID-19 has considerably left its mark on mental health. Aim: To describe the study population according to their clinicosocial, demographic profile, the level of anxiety prior to COVID19 rapid antigen testing, and to explore the determinants of anxiety among COVID-19 suspected patients. Materials and Methods: A cross-sectional survey was conducted in June, 2021-August, 2021 with a sample of 197 adult participants attending the fever clinic of Medical College, Kolkata, West Bengal, India. The data collection tool used was a predesigned, pretested structured schedule where the level of anxiety was measured with the Generalised Anxiety Disorder-7 (GAD-7) selfadministered questionnaire. Relevant frequencies, percentages, central tendencies, and dispersions were calculated. Results: Total of 197 responses were analysed, the mean age of respondents was 44.43± 16.54 years with 58.4% male. Among the patients, 64.5% were vaccinated and around 50.3% of total patients were partially or fully vaccinated by Covishield. Of the 197 respondents included in the study, 11.7% had anxiety (GAD score ≥10) before Rapid Antigen Testing (RAT) and among the participants who tested positive (70 patients), 10 patients (14.3%) had anxiety. Education, occupation, number of the symptoms and the symptoms of sore throat, myalgia and joint pain were significantly associated with the anxiety level. Number of symptoms, joint pain, fatigue, weakness and current fever status was significantly associated with RAT positivity. Conclusion: One out of every 10 patients attending fever clinic with suspected COVID-19 suffered from significant anxiety before the RAT test. These findings mandates linking counselling services with RAT testing facility at the fever clinic.
Impact of Black Summer 2019/20 Wildfires on True Bug Priority Species (Insecta: Hemiptera: Heteroptera) in the Northeast Forests of New South Wales
Authors: Cassis Gerasimos , Shofner Ryan , Laffan Shawn , Cheng Marina
Published: August 2022

This study examined the impact of the Black Summer 2019/20 wildfires in the Northeast Forests of New South Wales for seven priority heteropteran (= true bug) species, across a range of vegetation classes and host plants. Our area of study spanned 104,000 km2, from the Queensland border to the Hunter Valley, and west towards Narrabri.

We used data primarily from the Plant Bug Inventory database, inclusive of all phytophagous families of the suborder Heteroptera. We identified 122 survey sites based on their distribution in historical collection data and that of their known host plants. These sites were parsed into unburnt (69 locations) and burnt (53 locations), with the latter further categorised by fire severity.

The 122 sites were surveyed in four field trips in the late summer early autumn and spring of 2021. One or more of the priority species were detected at thirty-three sites (22 unburnt and 11 burnt sites). The first three field trips (January–March) resulted in the discovery of only Woodwardiola ‘n.sp_LOMA’. The fourth field trip (November) resulted in the discovery of four additional species (Kirkaldyella rugosa, Setocoris ‘n.sp_BINA’, Epimixia vulturna and Eritingis trivirgata), as well as W. ‘n.sp_LOMA’. The two other priority species (Kirkaldyella schuhi and Myrmecoroides grossi) were not found.

IUCN Red list methodology was employed to analyse the conservation status of the seven priority species. All seven priority species were found to be species of Least Concern for EEO and Data Deficient for AOO. The Data Deficient categorisation was decided based on insufficient sampling data plus expert opinion. Further sampling is required for all species but is critical for Kirkaldyella schuhi and Myrmecoroides grossi to determine whether their non-detection in this survey is due to sampling inadequacy or due to environmental factors.

Uma conquista formal que se destaca em A Mulher de Branco (1860), de Wilkie Collins, é a grande variedade de narradores, apresentados de tal modo a convertê-los em testemunhas que auxiliam na resolução do crime central do enredo, isto é, a troca das identidades de Laura Fairlie e Anne Catherick. Apesar de esse recurso adornar o texto com um manto de busca desinteressada pela verdade e legitimada pela imitação formal de uma Corte de Justiça, como se seu único objetivo fosse a reconstrução imparcial dos fatos e como se os testemunhos divergentes daqueles dos protagonistas tivessem igual espaço e peso que os demais, propõe-se que, na realidade, a personagem Walter Hartright edita os relatos dos outros narradores, estruturando o romance com mecanismos emprestados das práticas jornalística e, principalmente, jurídica, de modo a amparar a organização e a apresentação que faz das evidências, da maneira que melhor lhe convém para se destacar como o herói de um conflito maniqueísta e justificar sua ascensão social. Em outras palavras, propõe-se que Hartright seja um editor não confiável, que se utiliza de valores elevados, como a busca pela verdade em prol da justiça, e de práticas discursivas análogas, a jornalística e a jurídica, para enaltecer o que foi, em última instância, um ganho próprio.
UMA REFLEXÃO SOBRE AS MÚLTIPLAS REPRESENTAÇÕES DE SHAKESPEARE
Authors: Fraga Júlia Pereira
Published: August 2022

Shakespeare é um homem de muitas faces. Seu rosto está presente em pinturas, desenhos, filmes, séries e até mesmo bolos ou patinhos de borracha. Apesar disso, a incerteza ronda seus retratos considerados oficiais. Porém, há uma ideia construída coletivamente de como Shakespeare se parece: reconhecemos de imediato a figura relativamente calva, de rosto plácido e com feições aquilinas que não chegam a ser feias ou bonitas, usando um brinco em uma de suas orelhas e vestido com um colarinho branco que era moda nos séculos XVI e XVII. Esse reconhecimento da figura shakespeariana se dá pela reprodução da imagem do Bardo de Avon como um signo carregado de um sentido cultural. Nós, contemporâneos, reproduzimos esse signo a fim de colaborar com a bricolagem imagética que temos do texto de partida, que é a vida e a obra do maior dramaturgo inglês. Cada pessoa que reproduz a imagem shakespeariana modifica, parodia, presta homenagem e redesenha aquilo que se tem como a imagem tradicional. É nesse perpétuo ato de modificar a tradição que este ensaio pretende trazer uma reflexão sobre a perpetuação da vida e da obra de Shakespeare, tendo como base as reconfigurações feitas através dos anos.

An intravaginal foreign body of long duration can pose a diagnostic dilemma, since a number of diagnostic modalities may fail to detect its existence. We present the case of an 8‐year‐old girl who suffered from a bloody, malodorous vaginal discharge for over 4 years, during which time she had been evaluated by several gynecologists. A vaginal examination performed under analgesia revealed a pinpoint‐sized opening 2 cm above the hymen. We inserted a cannula and injected radio‐opaque contrast medium. An intravaginal filling defect was visible, which strongly suggested the presence of a foreign body. An incision through this scarred area was performed and two foreign bodies, one shaped like a plastic tube and the other a cap, were removed. We conclude that vaginography may provide an alternative diagnostic tool for this condition.
Aspiration and tetracycline sclerotherapy for management of simple ovarian cysts
Authors: AbdRabbo S. , Atta A.
Published: July 2002

Objective: To evaluate the procedure of aspiration and tetracycline sclerotherapy in the management of simple ovarian cysts. Methods: Twenty‐five cases of simple ovarian cysts were subjected to cyst fluid aspiration and 5% tetracycline injection under ultrasound guidance. Cytological examination of the aspirated fluid was carried out in 24 cases and the patients were followed for 6–36 months. Results: Cytology revealed a cellular sediment in 18 cases (simple cysts), follicular cells in four cases (follicular cysts), and blood and hemosiderin‐laden macrophages in two cases (endometriosis); subsequent surgery was required in only one case (endometriosis). Conclusions: The procedure of aspiration and tetracycline sclerotherapy was easy, safe and acceptable, with no recurrences. It appears to be a valid alternative to cyst aspiration in the management of simple ovarian cysts.

Objective: To evaluate the incidence of retroperitoneal metastases, survival rate and site of recurrence in early ovarian tumors undergoing limited retroperitoneal surgery. Method: Three hundred seventy‐three consecutive patients underwent assessment of the retroperitoneum consisting of intraoperative palpation with or without biopsies. Results: Retroperitoneal metastases were detected in 10 stage‐I tumors (3.2%) and in 10 stage‐II tumors (16%). The risk was inversely related to tumor differentiation. Palpation revealed metastases in 10 cases. During follow‐up, none of the borderline tumors (1.9% of stage‐I grade‐1 node‐negative, 2.7% of grade‐2 and 7.0% of grade‐3 tumors) recurred in the retroperitoneum. In stage II, two recurrences were observed in grade‐2 tumors (11%) and one in grade 3 (4.5%). Conclusion: Limited retroperitoneal surgery enables satisfactory outcome in early ovarian cancers. Risk of retroperitoneal recurrence is minimal in grade 1 and non‐existent in borderline tumors. Less differentiated tumors have low risk but further investigation of the therapeutic role of lymphadenectomy is justified.
Behavior of the small GTP‐binding protein rab6 in the liver of normal rats and rats presenting an acute inflammatory reaction

Published: July 2002

Summary— While it is known that the small GTP‐binding protein rab6 is localized in vitro to the Golgi apparatus of several mammalian cells, its behaviour in vivo has not yet been investigated. The aim of this work was to compare by immunocytochemistry and immunoblotting the distribution of rab6 in hepatocytes from normal rats and from rats with an acute inflammatory reaction, a circumstance where the synthesis and secretion of plasma proteins by the hepatocytes is increased and which is accompanied by several changes in the Golgi apparatus. Our results show that in normal rats, rab6 was present in all hepatocytes irrespective of the location of the cell in the hepatic lobule. At the ultrastructural level, rab6 was mainly visible on the three Golgi saccules, but in some cells it appeared to be absent in saccules corresponding to the cis or the trans saccule. The inflammatory reaction was accompanied by an increase of the immunocytochemical labelling at the light and electron microscopy levels. However, by immunoblotting, no differences in the total amount of rab6, nor in its subcellular distribution were found in liver cells after acute inflammatory reaction. These results demonstrate that rab6 is restricted in vivo to the Golgi apparatus and that no significant redistribution occurs during an acute inflammatory reaction.

The amino acid sequence of the winged bean acidic lectin (WBA II) was determined by chemical means and by recombinant techniques. From the N‐ and C‐terminal sequence, obtained chemically, primers were designed for PCR amplification of the genomic DNA. The PCR product was cloned and sequenced to get the complete primary structure of WBA II. Peptide fragments for sequencing were also obtained by tryptic cleavages of the native lectin. The WBA II sequence showed a high degree of homology with that of WBA I and Erythrina corallodendron lectin (ECorL), especially in the regions involved in subunit association, where there is a very high conservation of residues. This perhaps implies the importance of this particular region in subunit interactions in this lectin. In addition, many of the residues, involved in carbohydrate binding in legume lectins, appear to be conserved in WBA II. The distinct differences in anomeric specificity observed amongst WBA I, WBA II, ECorL and peanut agglutinin (PNA) may be explained by subtle differences in sequence/structure of their D‐loops. WBA II binds adenine quite strongly; a putative adenine binding sequence has been identified.
Identification of an optimal Ncx binding sequence required for transcriptional activation

The Ncx gene encodes a homeobox containing transcription factor that belongs to the Hox11 gene family. We determined specific Ncx protein binding consensus DNA sequences. Optimal Ncx binding sequences were 5′‐CGGTAATTGG‐3′ (TAAT core) and 5′‐CGGTAAGTGG‐3′ (TAAG core), which coincided with the Hox11 binding sequence. Both Ncx and Hox11 could bind to the TAAT and the TAAG core oligonucleotide in vitro. However, they could efficiently transactivate the reporter plasmid linked to the TAAT core sequence but not to the TAAG core sequence. Thus, Ncx and Hox11 act as transcriptional activators via their target sequence, 5′‐CGGTAATTGG‐3′.
Heterogeneity of astroglia cultured from adult human temporal lobe

Published: July 2002

This study characterized the morphological and electrophysiological diversity of astroglia cultured from adult human cerebral temporal lobe, and explored the influence of the cytokine interleukin‐1β on these cells. The cultures contained astroglia positive for glial fibrillary acidic protein which were flat, bipolar or multipolar in shape and variable in size. A subpopulation of the bipolar and multipolar cells was positive for S100 protein. The most striking feature of these cultures was the presence of glia with long (600 μm) processes with few branches or only terminal branches. Patch clamp recordings of the non‐stellate process bearing cells revealed prominent inward Na+ and transient and sustained outward K+ conductances. Distinct differences in the relative proportion of these conductances were evident among cells but did not appear to be correlated with cell morphology. Treatment of cultures with interleukin‐1β for 96 h did not change total protein content, but increased the content of S100β protein and decreased the content of glial fibrillary acidic protein. The findings indicate that cultures of adult human cerebrum contain subpopulations of morphologically and electrophysiologically pleomorphic glial fibrillary acidic protein positive astroglia, exhibit increased levels of the neurotrophic factor S100β when exposed to interleukin‐1β, and may serve as a useful model for investigation of glial involvement in neuropathology.
