Caminhar, descobrir, projetar
Authors: Simões Caetano Cabral Arthur
Published: February 2022

Nós descobrimos o mundo à medida que nos deslocamos por ele; inventamos o novo à medida que o que já existe se revela diante de nós. Em termos gerais, no que tange o fazer projetual que se volta à paisagem, assume-se, nas reflexões aqui presentes, a perspectiva de que nenhuma invenção pode ser tão absolutamente inovadora que prescinda do contato com aquilo que a precede, com as preexistências, com a materialidade da paisagem; por outro lado, parece razoável supor que o desvelamento daquilo que já existe, mas que não é, até então, reconhecido, corresponde, também, a uma forma de invenção. Esses pressupostos se respaldam, sobretudo, nas reflexões do geógrafo Jean-Marc Besse acerca da paisagem, entendida enquanto experiência fenomenológica, e de suas relações com o fazer projetual.
Paisagismo e documentação
Authors: Ferreira Alda
Published: February 2022

Em 2012, o sítio da Cidade do Rio de Janeiro recebeu o título de Paisagem Cultural da UNESCO, atribuído segundo os critérios V e VI de suas Diretrizes Operacionais. Contudo, até o momento, não houve a retificação do Dossiê, com a documentação dos atributos deste Patrimônio da Humanidade, e identificadas suas componentes chaves. Este artigo tem o objetivo de caracterizar a formação histórico-cultural das práticas paisagísticas na construção da Paisagem Cultural Carioca. Baseado no conceito de habitus e campo, do sociólogo Pierre Bourdieu, foi analisado o sistema de espaços paisagísticos que caracteriza a borda d’água do Sítio Nomeado. Observou-se que essa construção é fruto da noção ativa dos paisagistas, como produtos da história do campo social, e das experiências acumuladas no curso de suas trajetórias individuais em relação à sociedade e ao meio, que contribuiu para a construção de uma cultura paisagística. Defende-se então que é necessário conservar o valor paisagístico atribuído pela UNESCO, e salvaguardar os saberes gerados pelas práticas que colaboram para distinguir o lugar.
Mercado Municipal Vila Operária a Mercado Municipal Centro-Oeste
Authors: Mahler Christine Ramos , Mello Fernando Antonio Oliveira
Published: February 2022

Este trabalho trata dos mercados públicos – lugares de trocas de longa permanência histórica – no campo da teoria, história e crítica da arquitetura e do urbanismo. Traz como discussão o caso do Mercado Centro-Oeste de Goiânia, um dos três primeiros entrepostos de abastecimento quando ainda se formava a nova capital goiana. Ainda que tanto a feira quanto o mercado da antiga Vila Operária tivessem um importante papel ligado ao abastecimento e, sobretudo, às relações sociais que promoveram na região, o edifício do antigo mercado encontra-se subutilizado e em acelerado processo degradação. A condição de invisibilidade sobreleva a importância de sua documentação e do resgate de sua história.  Para  atingir esse intuito, o artigo foi elaborado a partir de pesquisa documental e levantamentos in loco, com uma breve abordagem acerca da história dos mercados públicos com ênfase na história da formação de Goiânia, seus bairros populares, em especial o Setor Centro-Oeste, anteriormente denominado Vila Operária. O Mercado Centro-Oeste, marco importante desse bairro, é analisado quanto à sua inserção urbana e do contraponto de seu uso original e de seu estado atual. Desse modo, interessam a documentação e a morfologia, tanto do mercado quanto da região em que se insere. Como contribuições, espera-se dar visibilidade ao bairro e ao mercado, demonstrar seu potencial a partir de seus valores originais e dos possíveis usos complementares que o integrem à dinâmica da cidade contemporânea.

Resgate, valorização, educação e documentação do patrimônio por meio de sketches
Authors: Kallas Luana M. E. , Guillen-Salas Juan Carlos , Silva Eliel Américo Santana da
Published: February 2022

Desde a pré-história podemos identificar o desenho e a pintura como forma de representação e registro da história. Os desenhos e pinturas eram a única forma de capturar um momento da história, os costumes, a fauna e a flora de um lugar, como apresentado por diversos naturalistas pelo mundo. No Brasil dos séculos XVII, XVIII e XIX, alguns expoentes desses naturalistas, como Jean Baptiste Debre, William John Burchell, Johann Moritz Rugendas, entre outros representaram as cidades mais importantes do Brasil, como Rio de Janeiro, São Paulo e desbravaram selva, rios e chegaram às aldeias e cidades do interior do país, registrando épocas, documentando-os para o presente e futuro. Hoje, os desenhistas de rua contemporâneos representam as cidades e ao mesmo tempo se aproximam e/ou se reaproximam do patrimônio de suas cidades por meio de desenhos. De outro lado, muitas pessoas, devido à rotina cotidiana deixam de conhecer o patrimônio da cidade, o que faz a população esquecer sua história e esse esquecimento leva ao descuido de seu patrimônio. Nesse sentido, este estudo parte da hipótese de que os sketches são uma forma de resgate, valorização, como também de documentação do patrimônio arquitetônico e urbanístico contribuindo para a consciência de uma herança cultural e uma educação patrimonial. Nesse sentido, o objetivo geral deste trabalho é identificar se os sketches urbanos são uma forma de resgatar, valorizar e documentar o patrimônio arquitetônico e urbanístico e se contribuem para uma consciência da herança cultural, ou seja, a educação patrimonial. A metodologia aplicada foi o levantamento do referencial teórico acerca do patrimônio, documentação e valorização; levantamento dos desenhos dos naturalistas do passado de Frans Post, José Joaquim Freire, Joaquim Jose Codina, Jean-Baptiste Debret e dos desenhistas de rua contemporâneos; um questionário aplicado para todo o Brasil, por meio do Google Forms, de forma remota e online, principalmente aos desenhistas de rua, sobre a temática do desenho e a valorização do patrimônio material e cultural; sistematização do questionário, apresentação dos resultados e discussão. Os resultados apresentaram que 102 dos 104 respondentes ao questionário acreditam que os desenhos ou sketches resgatam e valorizam o patrimônio material e cultural, arquitetônico e urbanístico. Dessa forma, o objetivo foi atendido e a hipótese comprovada, que os sketches são uma forma de resgatar, valorizar e documentar o patrimônio arquitetônico e urbanístico e, ao mesmo tempo, contribuem para a educação patrimonial.
Ferramentas digitais na conservação do art déco
Authors: Lima Fábio
Published: February 2022

Os edifícios históricos podem nos comunicar uma grande quantidade de informações e fundam numa determinada comunidade um sentido de origem, assim como qualidades singulares de identidade. Para uma cidade que estava sendo construída, o patrimônio art déco de Goiânia surgiu principalmente como caráter simbólico de poder e progresso. Hoje, bastante disperso no meio de tantas outras edificações, requer considerações sensíveis. Esse tipo de arte edificada não é simples resultado da composição funcional de volumes, nem muito menos mera decoração de superfície, mas a representação de visões e valores de época. Constituem inegáveis bens culturais que devem ser investigados para fins de melhores usos urbanos, como referências fundamentais na compreensão do passado. Dentro das nossas atuais circunstâncias, as tecnologias digitais são ferramentas que podem contribuir decisivamente na conservação desse patrimônio.
Methodology of continuity of results of various levels of professional pedagog-ical education
Authors: Tarkhanova Irina
Published: February 2022

The relevance of the research subject is determined by the need for application of the principles of consistency and continuity in the training of pedagogical resource personnel. The system of continuous pedagogical education cannot function effectively without value orientations being defined for each stage of teacher education with respect to the professionally significant qualities, meanings and values student teachers possess. The aim of the article is to substantiate the methodology of continuing pedagogical education. Methods of analysis of professional and educational standards are applied. The result of the analysis is a list of value orientations of professional pedagogical activity. The empirical study was conducted using the questionnaire and MAST-test methods. The results state a common system of values and the difference in emphasis at different levels of teacher training (teacher training classes, teacher training colleges, universities, postgraduate education). As a result of the analysis, the universal pedagogical competencies necessary for the effective development of pedagogical activity are identified. These competencies allow the teacher to consciously perform labor functions, carry out training, education and development of the student, design the educational environment, interact with all subjects of the educational process. The article describes the indicators of the formation of universal pedagogical competencies for different levels of teacher training.
Helping Content Strategy: What Technical Communicators Can Do for Non-Profits
Authors: Getto Guiseppe , Flanagan Suzan
Published: February 2022

Purpose: Contemporary non-profit organizations must reach a variety of audiences in order to sustain themselves and must compel these audiences to take action on behalf of a specific cause. At the same time, past research has indicated that non- profit professionals often lack
the necessary training and expertise to leverage digital technologies for effective communication. This research study explores how technical communicators can assist non-profits by helping them develop effective content strategies.
 Method: This report of research findings
is based on an ongoing Participatory Action Research (PAR) project, which included a series of focus groups with representatives of thirteen different organizations as well as interventions with several other organizations. The goal has been to learn about and help improve non-profit content
strategy in the community of Greenville, North Carolina.
 Results: We found that while non-profits do rely on a variety of media to fulfill their goals, they prefer pre-digital media. Our participants also defined audiences in a very loose manner, used content in a non-targeted
way, and favored existing organizational processes over content strategy best practices.
 Conclusions: Ultimately, we provide several ways technical communicators can assist non-profits through low-cost or free consulting and the development of educational materials. We hope
that fellow professionals will engage in this necessary work because non-profits in the United States form an important "third sector" of the economy that provides essential services to countless individuals.
Snowpocalypse 2021: Understanding Stakeholder Topoi in the 2021 Texas Power Grid Failure
Authors: Harlow Rachel Martin
Published: February 2022

Purpose: This research is the first step in exploring how public policymakers use the expert knowledge and nonexpert knowledge they acquire in oversight hearings. This step is focused on learningwhat the testimony in oversight hearings reveals about how the primary stakeholders of the February 2021 power loss event understood that event.
Method: The researcher used NVivo, a content analysis application, to examine public comments, witness testimony, and a combination of legislators' press releases and the text of bills they drafted. All texts were generated in February and March 2021. The researcher ran both a word frequency analysis and a thematic analysis of each set of texts to identifytopoiused by each stakeholder group and compared the results.
Results: The analysis revealed that the three primary stakeholder groups perceived the February 2021 power loss event differently, though some of the most salient, significant, or urgent concerns of each group overlapped. The stakeholder groups shared sometopoi, but the ways each group used thosetopoisuggested different ways of understanding and interpreting the event.
Conclusions: Technical communicators who are tasked with reconciling technical and nontechnical audiences in situations like this can use the techniques discussed here to better identify specific places where the respective groups' use oftopoidiverged from one another or aligned with one another. The more that is known, and not just surmised, about stakeholders and how they understand and interpret their technical knowledge, the better we can address how that knowledge may be communicated throughout the legislative process.
Signaling Context in Topic-Based Writing
Authors: Swarts Jason
Published: February 2022

In topic-based writing delivered as web help or interactive PDF, readers are able to access topics non-linearly, reading only those topics they feel a need to read. Consequently, readers can easily lose a sense of a topic's broader context of related topics and concepts, which is knowledge
presumed of a "qualified reader."
 Purpose: This paper investigates how relative "that" and "which" clauses are used to signal context in writing that is intended to be free of obligatory contextual connections to other topics in a documentation set.
 Method:
This analysis relies on a computer-assisted, descriptive analysis of relative pronoun use in a corpus of published, topic-based documentation. The analysis focuses on "that" and "which," typically used in English to refer to and add information (e.g., a context) about an antecedent noun.

Results: Relative "that" and "which" clauses are shown to be used in a variety of ways in topic-based writing to signal associations between topics, making it easier for readers who need context to find it.
 Conclusions: The author offers implications for writing practice
that include deliberate, strategic use of "that" and "which" and complementary documentation design that enables readers to locate contextual information signaled by those pronouns.
The Future of Eurasia: In the Vice between Transatlanticism and Chinese Expansion?
Authors:   University of Kent, Sakwa Richard
Published: February 2022

Eurasia that encompasses Russia and major countries of the former Soviet Union currently finds itself squeezed between Transatlantic alliance whose influence dominates in political and economic life of the UK and EU, and growing power of Asia, primarily China and a number of other emerging economies of the Asia-Pacific region. To sustain a leading world and regional role, Russia has to define its place and primary goals in Eurasian space. The article examines different scenarios of Eurasian integration, various Eurasianism concepts and possible future of Russian influence in Eurasia.
“Nebuchadnezzar Archetype” of Eurasian Cultures in Nikolay Leskov’s Eurasian Concept: Implications for Modern Russia
Authors:   Galway Chronicle, O’Néill Rosamond Eileen
Published: February 2022

In his literary works, the prominent Russian writer Nikolay Semenovich Leskov (1831-1895) introduced the concept of “Nebuchadnezzar’s archetype” of Russian mentality, that is, according to Leskov, a Eurasian mentality. Leskov opposed “holy foolishness,” a part of the described Eurasian archetype, to European rationality that distanced itself from God as a result of Enlightenment. However, the writer distinguished between the “holy foolishness” for God’s sake, a constituent of Russian mentality, and the “holy foolishness” for own sake, a component of Russian official state politics, that he regarded as an absolute evil. In “Nebuchadnezzar’s archetype,” Nikolay Leskov saw a reaction of the Russian national mentality to a number of heavy military and diplomatic defeats of Russian Empire caused by Europe in the mid-nineteenth century (e.g. Crimean war, Russo-Turkish war of 1877-1878). After these defeats, according to Leskov, Russian nation turned to its Eurasian origins, while Russian government kept loyalty to European-style of politics. In the article, I demonstrate the implications of Leskov’s concept of “Nebuchdnezzar’s archetype” for understanding and classifying modern Russian politics in Eurasian space.
Pre-Eurasian Motives in Russian Social Thought of the Nineteenth Century: Intersections of Chinese Influence as a Far East Culture and Egyptian Influence as a Mediterranean Culture
Authors:   Russian State University for the Humanities, Serbinenko Vyacheslav V.
Published: February 2022

Without proper understanding of Russian pre-Eurasian thought of the nineteenth century, we cannot have a full picture of Russian Eurasianism as a political movement of the 1920-1930s. I analyse the ways in which Chinese and Egyptian cultural influence shaped pre-Eurasianism of Russian nineteenth-century social thinkers Vladimir Solovyev, Nikolay Danilevsky and Vasily Rozanov.

EFL Students’ Perceptions of Google Docs as an Interactive Tool for Learning Writing
Authors: ALDOSSARY Khaled
Published: February 2022

The present study aimed to explore the perceptions of Saudi tertiary-level students toward using Google Docs as a learning tool in English as a foreign language (EFL) writing classes. Adopting a quantitative approach, 164 Saudi EFL students studying writing at three different academic levels completed a questionnaire about their perceptions of utilizing Google Docs as an alternative learning platform to learn writing and interact with teachers and peers. The findings showed that the participants perceived Google Docs useful and interesting. They also indicated that Google Docs could establish a collaborative learning environment. Their use enhanced student-teacher and student-student interactions, improved students’ overall writing skills, and encouraged constructive peer-to-peer discussions. The study suggests that Google Docs plays a significant role in promoting learners’ motivation and involvement in learning second language writing. It concludes with some limitations and provides recommendations for future research.

Pembangunan jalan tol Semarang – Solo didasarkan oleh rencana dari pemerintah untuk membangun jaringan jalan tol Trans Jawa. Jalan tol ini dibangun menggunakan perkerasan kaku. Perkerasan kaku digunakan karena mempunyai kekuatan atau daya tahan yang lebih tinggi, memiliki modulus elastisitas yang tinggi dan perawatan yang lebih mudah dan murah khususnya bila dibandingkan dengan perkerasan lentur. Perencanaan ulang ini dilakukan untuk mengetahui apakah perencanaan perkerasan jalan yang sebelumnya sudah ada itu sudah sesuai dan untuk membandingkan perencanaan jalan yang sudah ada dengan perencanaan jalan yang baru. Perencanaan ini akan dilakukan dengam menggunakan 2 metode yaitu Metode AASHTO 1993 dan Metode Bina Marga 2003 untuk melihat sejauh mana perbedaan ketebalan yang didapatkan. Metode AASHTO dipilih karena metode ini dipakai secara umum diseluruh dunia, sedangkan metode Bina Marga 2003 dipilih karena merupakan penyederhanaan dari metode AASHTO yang sudah disesuaikan dengan kondisi alam yang ada di Indonesia. Metode AASHTO menggunakan parameter Reability (R) dalam satuan persen (%), sementara metode Bina Marga 2003 menggunakan parameter Faktor Keamanan Beban (FKB), metode AASHTO beban lalu lintas yang dijadikan acuan yaitu repetisi beban sumbu standar 18 kips (ESAL) yang terjadi masa layanan perkerasan, sedangkan metode Bina Marga 2003 beban dikelompokkan berdasarkan berat dan konfigurasi sumbu tiap kendaraan. Nilai beban lalu lintas yang dijadikan acuan adalah perbandingan repetisi tiap jenis sumbu dan repetisi yang diijinkan. Metode AASHTO memperhitungkan parameter koefisien drainase (Cd), sedangkan metode Bina Marga 2003 tidak diperhitungkan. Hasil perhitungan perkerasan kaku menggunakan Metode AASHTO 1993 didapatkan tebal perkerasan kaku 27 cm, dowel Ø32 mm, jarak 350 mm, dan panjang 460 mm, tie-bar D13 mm, jarak 750 mm, dan panjang 650 mm. Hasil perhitungan menggunakan Metode Bina Marga 2003 didapat tebal perkerasan kaku 23 cm, dowel Ø 32 mm, jarak 300 mm, dan panjang 450 mm, tie bar D16 mm, jarak 750 mm, dan panjang 700 mm.

Current reports on foot and ankle injuries of American football players
Authors: Wodka-Natkaniec Ewa , Niedźwiedzki Łukasz , Pawłowska Justyna , Zyznawska Joanna , Świtoń Anna
Published: February 2022

Background. The purpose of this study was to collect current research lines in Ame­rican football regarding the ankles and the foot. The specific goal was to determine how American football affects the ankle joints and the foot, i.e. the frequency, causes and types of injuries as well as various links between the footwear and failure of these structures.
Material and methods. The study included 26 publications, drawn mainly from PubMed and related databases, meeting the search criteria.
Results. As a result of the review of the publications, the frequency and types of ankle and foot injuries with regard to lower limbs were discussed along with the conditions predisposing for such injuries. Current works focus primarily on injury surveillance databases and on the research on the impact of footwear on the foot and ankle joint. There are works showing the relationship between ankle and foot injuries on the one hand, and the balance on the other. Additionally, some of the articles deal with the past treatments, the time of exclusion from the game and the use of stiffeners to protect the players against overloads and damage to the above-mentioned structures.
Conclusions. Our research draws attention to the problem of foot and ankle injuries and shows that preventive, training and physiotherapeutic programs should still be improved due to their high level of trauma. More clinical study is needed to find the specific causes of injuries and prevent them effectively.
Increasing the measurement of soil water content with the characterization of magnetic field induction sensors using model equations for the internet of thing application

Published: February 2022

This study proposes an increase in the measurement of soil water content with sensor characterization that can be integrated with the internet of things. The main contribution of this work is the improvement in measurement accuracy compared to measurements using a moisture meter. This is achieved through an electromagnetic approach using a pair of transceiver coils as a sensor. Determination of water content in the soil is carried out through the formulation of an equation model that connects the measured voltage on the receiving coil with the mass of water contained. It is known that the use of the equation model in the test data results in better accuracy with an error of 2.03% - 17.43%, compared to measurements using a moisture measuring device with an error of 13.21% - 32%. This equation model that uses the electromagnetic method provides an alternative solution for determining the soil water for wider land use so that can be used for internet of things application.
General practitioners do not counsel more physical activity after a public health campaign
Authors: Lion A , Lethal J , Delagardelle C , Seil R , Urhausen A , Theisen D
Published: February 2022

A physical activity (PA) promotional campaign was launched in June 2018 to raise awareness of the health benefits of PA in patients with chronic diseases in Luxembourg. This study aimed to evaluate the behavior of general practitioners (GPs) regarding PA counselling before and after the campaign. The campaign consisted of advertisement broadcasts on national TV/radio in June and July 2018 and comprised a toolkit (flyers and a PA evaluation tool) sent in September 2018 to all medical doctors registered in Luxembourg. PA counselling behaviors were evaluated in 59 and 53 GPs who answered a standardized questionnaire before and after the campaign, respectively. Interviewed GPs declared having advised only a small proportion of their patients regarding PA participation before and after the campaign (29% and 24%, respectively; p<0.001). The campaign had no impact on the GPs’ awareness (21%) about the national program offering PA for patients with chronic diseases. Lack of time and knowledge were identified as the main barriers to engaging in PA counselling. Overall, GPs encouraged only a small proportion of their patients to engage more in PA, and the awareness campaign failed to change their PA counselling behavior, at least in the short term. Barriers to PA promotion within primary healthcare should be addressed before implementing new awareness campaigns targeting healthcare professionals.

The clinical and scientific impact of an institutional ACL registry: Luxembourgish experience
Authors: Mouton C , Nührenbörger C , Magosch A , Hoffmann A , Pape D , Seil R
Published: February 2022

A standardized clinical pathway/registry for ACL injuries was developed in 2011 in our institution to monitor patient, injury and clinical profiles on a systematic basis regardless of operative or non-operative treatment. It was aimed from the very beginning for both patient care and research purposes. The aim of this paper is to share the Luxemburgish experience of this in-house registry, from its organization to the results of its publications. Our findings indicated that there was not only a big interindividual variability of physiological knee structures, but also of injury types, thereby showing that isolated ACL injuries were rare and that a personalized medicine approach of ACL injuries is required. Our findings about individual patient profiles, structural soft-tissue damage such as meniscal injuries, as well as factors contributing to the potential decompensation of knee laxity over time are some of the major discoveries over the last decade. Other findings such as the periodicity of ACL injuries in organized team ball sports, the high variability of knee morphology, references to understand the course/progression of ACL reconstructed patients and movement analyses are also of great value to reach high quality in patient care and continuous innovation in knee surgery.

Desenvolvimento curricular em matemática a partir de projetos integradores: estudo com professoras em formação inicial
Authors: Januario Gilberto
Published: February 2022

Levar licenciandas a estudar temas do currículo e a experienciar práticas que rompessem com a lógica disciplinar e linear do processo de educar matematicamente motivou a criação de oportunidade para colocá-las no processo de autoria de suas aprendizagens. Neste artigo analisamos 39 projetos integradores concebidos a partir do levantamento de aspectos da realidade local e problemas socais de onde estudantes e escola estão inseridos, para os quais as licenciandas de uma turma do curso de Pedagogia atuaram como autoras. Trata-se de um estudo do tipo análise documental, conduzido pelo objetivo de problematizar o desenvolvimento curricular em Matemática a partir de projetos integradores como prática na formação inicial de professores. A atividade de elaborar esses projetos levou as licenciandas a considerar que a construção do conhecimento implicado em questões e problemas da realidade global ou local envolve estudo, reorganizações e desconstrução da imagem do professor como único detentor do conhecimento. Também indicou a necessidade de se investir em conhecimentos específicos de Matemática e de metodologias de ensino.

Published: February 2022

O objetivo desta pesquisa é medir a atitude em relação à matemática dos futuros professores da Educação Infantil de uma universidade da zona central do Chile. Para atender a esse objetivo, foi realizada uma investigação de nível quantitativo e descritivo, aplicando a escala de atitudes em relação à matemática. A amostra foi composta por 38 futuros professores de Educação Infantil de uma instituição de Ensino Superior na região central do Chile. Dentre os resultados, destaca-se a pontuação elevada para as afirmações: "Considero a matemática uma disciplina muito necessária nos meus estudos (x: 4,70; s: 0,52) e "A matemática pode ser útil para quem decide seguir uma carreira em “ciências”, mas não para o resto dos alunos” (x: 4,66; s: 0,63). Além disso, as afirmações com o valor médio mais baixo são: "Me diverte falar com os outros sobre matemática" (x: 2,76; s: 1,28) e "Gostaria de ter uma ocupação em que tivesse de usar matemática" (x: 3,13; s: 1,34). Conclui-se, apesar de a maioria dos depoimentos obter uma avaliação positiva, há a necessidade de gerar instâncias de formação nas quais os futuros professores aprimorem sua atitude em relação à matemática.

The Friction Coefficient Investigation during Electrochemical Baromembrane Separation of Model Solutions
Authors: Shestakov K.V.
Published: February 2022

A large number of scientific papers in recent decades have been devoted to the mathematical description of a mass transfer of substances through membranes. The choice of a mathematical model is to be carried out depending on the specific separation process used. This study represents a verification of how the predicted value of the solute flow density obtained using pre-calculated friction coefficients corresponds to real experimental data for electrochemical baromembrane separation of model solutions. The experimental and theoretically calculated values of the Ni (II), Cu (II), and Fe (III) cations flux density through the heterogeneous cellulose acetate membranes MGA-95 and MGA-100 are compared. It is established that the use of the mass transfer friction model is quite effective in predicting the kinetic characteristics of electrochemical membrane separation of solutions using semipermeable membranes. The calculation error in most cases is within one percent.
Enhanced Load Balanced Clustering Technique for VANET Using Location Aware Genetic Algorithm
Authors: MADASAMY Bhuvaneswari , BALASUBRAMANIAM Paramasivan
Published: February 2022

The vehicular Adhoc Network has unique charac-teristics of frequent topology changes, traffic rule-based node movement, and speculative travel pattern. It leads to stochastic unstable nature in forming clusters. The re-liable routing process and load balancing are essential to improve the network lifetime. Cluster formation is used to split the network topology into small structures. The reduced size network leads to accumulating the topology information quickly. Due to the absence of centralised management, there is a pitfall in network topology man-agement and optimal resource allocation, resulting in ineffective routing. Hence, it is necessary to develop an effective clustering algorithm for VANET. In this paper, the Genetic Algorithm (GA) and Dynamic Programming (DP) are used in designing load-balanced clusters. The proposed Angular Zone Augmented Elitism-Based Im-migrants GA (AZEIGA) used elitism-based immigrants GA to deal with the population and DP to store the out-come of old environments. AZEIGA ensures clustering of load-balanced nodes, which prolongs the network lifetime. Experimental results show that AZEIGA works appreciably well in homogeneous resource class VANET. The simulation proves that AZEIGA gave better perfor-mance in packet delivery, network lifetime, average de-lay, routing, and clustering overhead.
Human spinal cord in vitro differentiation pace is initially maintained in heterologous embryonic environments
Authors: Dady Alwyn , Davidson Lindsay , Halley Pamela A , Storey Kate G
Published: February 2022

Species-specific differentiation pace in vitro indicates that some aspects of neural differentiation are governed by cell intrinsic properties. Here we describe a novel in vitro human neural-rosette assay that recapitulates dorsal spinal cord differentiation but proceeds more rapidly than in the human embryo, suggesting that it lacks endogenous signalling dynamics. To test whether in vitro conditions represent an intrinsic differentiation pace, human iPSC-derived neural rosettes were challenged by grafting into the faster differentiating chicken embryonic neural tube iso-chronically, or hetero-chronically into older embryos. In both contexts in vitro differentiation pace was initially unchanged, while long-term analysis revealed iso-chronic slowed and hetero-chronic conditions promoted human neural differentiation. Moreover, hetero-chronic conditions did not alter the human neural differentiation programme, which progressed to neurogenesis, while the host embryo advanced into gliogenesis. This study demonstrates that intrinsic properties limit human differentiation pace, and that timely extrinsic signals are required for progression through an intrinsic human neural differentiation programme.

Interactions of developing T cells with Aire+ medullary thymic epithelial cells expressing high levels of MHCII molecules (mTEChi) are critical for the induction of central tolerance in the thymus. In turn, thymocytes regulate the cellularity of Aire+ mTEChi. However, it remains unknown whether thymocytes control the precursors of Aire+ mTEChi that are contained in mTEClo cells or other mTEClo subsets that have recently been delineated by single-cell transcriptomic analyses. Here, using three distinct transgenic mouse models, in which antigen presentation between mTECs and CD4+ thymocytes is perturbed, we show by high-throughput RNA-seq that self-reactive CD4+ thymocytes induce key transcriptional regulators in mTEClo and control the composition of mTEClo subsets, including Aire+ mTEChi precursors, post-Aire and tuft-like mTECs. Furthermore, these interactions upregulate the expression of tissue-restricted self-antigens, cytokines, chemokines, and adhesion molecules important for T-cell development. This gene activation program induced in mTEClo is combined with a global increase of the active H3K4me3 histone mark. Finally, we demonstrate that these self-reactive interactions between CD4+ thymocytes and mTECs critically prevent multiorgan autoimmunity. Our genome-wide study thus reveals that self-reactive CD4+ thymocytes control multiple unsuspected facets from immature stages of mTECs, which determines their heterogeneity.

How a cell changes from one stable phenotype to another one is a fundamental problem in developmental and cell biology. Mathematically, a stable phenotype corresponds to a stable attractor in a generally multi-dimensional state space, which needs to be destabilized so the cell relaxes to a new attractor. Two basic mechanisms for destabilizing a stable fixed point, pitchfork and saddle-node bifurcations, have been extensively studied theoretically; however, direct experimental investigation at the single-cell level remains scarce. Here, we performed live cell imaging studies and analyses in the framework of dynamical systems theories on epithelial-to-mesenchymal transition (EMT). While some mechanistic details remain controversial, EMT is a cell phenotypic transition (CPT) process central to development and pathology. Through time-lapse imaging we recorded single cell trajectories of human A549/Vim-RFP cells undergoing EMT induced by different concentrations of exogenous TGF-β in a multi-dimensional cell feature space. The trajectories clustered into two distinct groups, indicating that the transition dynamics proceeds through parallel paths. We then reconstructed the reaction coordinates and the corresponding quasi-potentials from the trajectories. The potentials revealed a plausible mechanism for the emergence of the two paths where the original stable epithelial attractor collides with two saddle points sequentially with increased TGF-β concentration, and relaxes to a new one. Functionally, the directional saddle-node bifurcation ensures a CPT proceeds towards a specific cell type, as a mechanistic realization of the canalization idea proposed by Waddington.

Shrimp aquaculture has been accomplished with breeding and nursing of shrimp in an artificial environment to fulfill the increasing demand of shrimp consumption worldwide. However, the microbial diseases appear as a serious problem in this industry. The study was designed to identify the diverse bacteria from shrimp PL (post-larvae) nurseries and to profile antibiotic resistance patterns. The rearing water (raw seawater, treated and outlet water) and shrimp PL were collected from eight nurseries of south-west Bangladesh. Using selective agar plates, thirty representative isolates were selected for 16S rRNA gene sequencing, antibiotic susceptibility test and MAR index calculation. Representative isolates were identified asAeromonas caviae, Pseudomonas monteilii, Shewanella algae,Vibrio alginolyticus, V. brasiliensis, V. natriegens, V. parahaemolyticus, V. shilonii, V. xuii, Zobellella denitrificanswhich are Gram-negative, andBacillus licheniformisandB. pumiluswhich are Gram-positive. Notably, six strains identified asAcinetobacter venetianusmight be a concern of risk for shrimp industry. The antibiotic resistance pattern reveals that the strain YWO8-97 (identified asP. monteilii) was resistant to all twelve antibiotics. Ceftazidime was the most powerful antibiotic since most of the studied strains were sensitive against it. The six strains ofA. venetianusshowed multiple antibiotic resistance patterns. MAR index were ranged from 0.08 to 1.0, and values of 26 isolates were more than 0.2 which means prior high exposure to the antibiotics. From the present study, it can be concluded that shrimp PL nurseries in southern part of Bangladesh are getting contaminated with antibiotic resistant pathogenic bacteria.

Inorganic and synthetic flocculants are widely investigated for removing harmful microalgae, such as Microcystis aeruginosa. However, their toxicity and non-biodegradability are shortcomings. Bioflocculants based on extracellular polysaccharides have attracted much attention as alternative flocculants. However, its high production cost is a limiting factor for applying bioflocculants. Here, we investigate the potential of the dead cells of a marine filamentous bacterium, Aureispira sp. CCB-QB1, as a novel flocculant on M. aeruginosa cells. The removal efficiency of M. aeruginosa cells by the dead cells was measured by mixing and shaking both components in a buffer with 5 mM CaCl2 in different incubation times and concentrations of the dead cells. After that, the minimum effective concentration of CaCl2 was determined. The combination effect of FeCl3 and the dead cells on the removal efficiency was tested. The structure of cell aggregates consisted of the dead cells and M. aeruginosa cells were also observed using a scanning electron microscope. The maximum removal efficiency (75.39%) was reached within 3 min in the presence of CaCl2 when 5 mg/ml of the dead cells (wet cells) were added. The optimal concentration of CaCl2 was 5 mM. The combination of the dead cells and a low concentration of FeCl3 (10 mg/L) with 5 mM of CaCl2 significantly improved the removal efficiency by about 1.2 times (P < 0.05). This result indicates that the combination usage of the dead cells can reduce the use of FeCl3. These results indicated that the dead cells could potentially be a novel biolfocculant to remove M. aeruginosa cells.

Introduction: Fluid absorption and associated electrolyte derangement is an inevitable complication of Transuretheral Resection of Prostate (TURP) and Percutaneous Lithotripsy (PCNL). The present study was conducted to analyse changes in serum electrolytes, Lactate Dehydrogenase (LDH) and acid base status, and to evaluate their role as early predictors of clinical and haemodynamic changes following continuous irrigation during transurethral resection of prostrate and PCNL Aim: To analyse the various biochemical changes during endourological procedures and to determine their role in predicting clinical manifestation and haemodynamic changes in these procedures. Materials and Methods: The present observational study included 20 patients, who underwent TURP and 20 patients who underwent PCNL. A 1.5% glycine and 0.9% normal saline were used for irrigation during TURP and PCNL, respectively. The levels of serum sodium, potassium, free calcium ion, LDH and acid base status were monitored in all patients preoperatively, intraoperatively, at the end of surgery, 6 hours and 24 hours postoperatively. Intraoperative and postoperative haemodynamic parameters were also studied. Results: In TURP group, statistically significant changes were seen in serum sodium, potassium, LDH and free calcium ions. There was no change in acid-base status of patients. In PCNL group, statistically significant changes were seen in serum sodium, LDH, free calcium ion and acid base status. It was observed that some of these changes persisted even 24 hours, postoperatively. However, despite the above changes, the haemodynamic parameters remained within normal limits. Conclusion: Changes in serum sodium, serum potassium and free calcium ion during TURP and PCNL were consistent findings which implies fluid absorption. These changes persist up to 24 hours postoperatively. The monitoring of these parameters in postoperative period should be continued especially in patients suspected to develop or having TURP syndrome.
