Authors: Hanafi Ahmed M. , Ibrahim Mohamed A. , Abou-deif Taher M. , Morcos Samy M.
Published: September 2023

This study focuses on enhancing indoor air quality and thermal comfort in indoor swimming pool facilities through the investigation of ventilation system configurations. Creating a comfortable and healthy environment in these facilities is crucial for the well-being of occupants and overall operational efficiency. The performance of the ventilation system significantly influences user comfort, energy consumption, and air quality. This research aims to analyze the impact of different ventilation system configurations on indoor air quality and thermal comfort parameters using computational fluid dynamics (CFD) simulations.

To achieve the research objectives, CFD simulations were conducted using ANSYS Fluent ®, a widely used commercial CFD package. The simulations involved solving the governing equations for continuity, momentum, energy, and species transport, along with employing the k-epsilon turbulence closure model. A high-resolution mesh with over 5.6 million elements accurately captured the flow regimes and related phenomena.

The study investigated various aspects of ventilation system configurations, including the placement and design of inlets and outlets, airflow rates, and distribution patterns. Evaluations were made based on key performance indicators such as indoor air quality parameters, thermal comfort indices, and energy efficiency metrics. Comparisons were made between different configurations to identify the most effective strategies for enhancing indoor air quality and thermal comfort.

The findings of the study demonstrate the importance of ventilation system design in achieving optimal indoor air quality and thermal comfort in indoor swimming pool facilities. The results indicate that specific configuration choices, such as the use of circular inlets in the ceiling for improved spectator comfort and rectangular inlets in the side walls for better performance in the swimming pool area, can significantly impact thermal conditions and air distribution. Additionally, the study emphasizes the need for appropriate inlet grille height to ensure adequate air mixing and thermal comfort.

The outcomes of this research provide valuable insights for architects, engineers, and facility managers involved in the design, construction, and operation of indoor swimming pool facilities. By understanding the impact of different ventilation system configurations, stakeholders can make informed decisions to optimize indoor air quality, thermal comfort, and energy efficiency. Ultimately, this research contributes to the development of sustainable and comfortable indoor swimming pool environments that cater to the needs of occupants and enhance their overall experience.
Arthropod Taxonomy Orders Object Detection in ArTaxOr dataset using YOLOX
Authors: Mazen Fatma M. A.
Published: September 2023

The detection and classification of insect species represent challenging computer vision tasks that have significant applications in zoology and agriculture. Fortunately, biologists and taxonomists have developed a systematic approach to organizing organisms, which results in a hierarchical classification system. Insect classification employs a hierarchical structure that includes object detection at the order level, family classification, and species classification. However, the conventional insect identification method is time-consuming and requires the expertise of highly skilled taxonomists to identify insects accurately based on morphological characteristics. This paper presents a pioneering study on the automatic detection and classification of Arthropod Taxonomy Orders using an enhanced variant of the You Only Look Once (YOLOX) framework along with the Arthropod Taxonomy Orders Object Detection (ArTaxOr) Dataset. The proposed ArTaxOr dataset encompasses diverse arthropod species such as insects, spiders, crustaceans, centipedes, millipedes, and isopods. Moreover, some images within this dataset depict multiple species with varying sizes, shapes, and colors. Accordingly, all images are resized to 640 $$\times$$
×
 640 to ensure compliance with the requisite input image size for YOLOX. Further, mosaic augmentation is employed to enhance the model’s accuracy in recognizing small objects. Inspite of natural complexity in a majority of dataset images, the proposed YOLOX-based model attained superior mean average precision. The outcomes of this study could act as a standard against which forthcoming research in this domain could be compared or judged.

Published: September 2023

Lower energy consumption while preserving the required light brightness is one of the main purposes of changing from an HPSV lighting system to a LED lighting system for road lighting. The current practice of changing whole luminaires requires a huge capital cost. Although LED lamps have a high illumination rate, the lamp structure which is different from existing HPSV lamps may improve the light intensity. This condition causes changes to the original lighting design and may not meet the requirements. Therefore, the aim of this research is to study the photometric distribution of LED and HSPV lamps based on simulation analysis. Both lamps are simulated using Dialux Evo simulation software by varying pole distances according to MS 825:2007 and BS EN 13201-2: 2004 standards. The study involves average luminance, overall uniformity, longitudinal uniformity, and threshold increment parameters. The results show that the average luminance value of the LED replacement lamps is lower than HPSV lamps, with a reduction of 52%. However, there is a minimal change in the light distribution pattern with an overall uniformity difference of 2% and a longitudinal uniformity difference of 18%. The results will be useful for local authorities and manufacturers to study on usage of different LED lighting systems. Energy consumption can be reduced while preserving the required lighting level.
Partial ponderomotive forces of Alfvén waves in near-Earth plasma
Authors: Guglielmi Anatol , Feygin Feliks
Published: September 2023

In the study of the ponderomotive action of Alfvén waves on near-Earth plasma, the general formula for ponderomotive forces, known in classical electrodynamics of continuous media, was previously used. The formula does not explicitly take into account the multi-ion composition of the plasma. Under the action of the waves, significant changes were found in macroscopic parameters — plasma density and velocity. Plasma in Earth’s magnetosphere contains ions with different charge-to-mass ratios. Besides hydrogen and helium ions, the plasma has an admixture of oxygen ions of ionospheric origin, as well as an admixture of other heavy ions. In this connection, a wide range of problems arise on the ponderomotive separation of ions of various types. To solve these problems, it is proposed to use partial ponderomotive forces and to describe the plasma not by hydrodynamic, but by quasi-hydrodynamic equations. In this paper, we discuss the derivation of partial forces for a traveling monochromatic Alfvén wave, and also suggest a method for deriving more general formulas by expanding the classical formula, known in macroscopic electrodynamic, into the sum of partial forces. The ponderomotive separation of ions is illustrated by the example of the problem for diffusion equilibrium of magnetospheric plasma. We propose a hypothesis that Alfvén waves redistribute plasma along geomagnetic field lines in such a way that the plasma at the magnetic field minima is characterized by an increased content of heavy ions. We suggest that a small admixture of heavy ions exists in the polar wind jet stream. The article is dedicated to the 80th anniversary of the discovery of Alfvén waves.
Oral cancer: licensed to kill?
Authors: Choi Siu-Wai , Sharma Dileep , Ramamurthy Poornima , Thomson Peter
Published: September 2023

Oral squamous cell carcinoma (OSCC) is a lethal disease of global significance. Having previously demonstrated a rising incidence and worsening mortality in a retrospective analysis of 9,887 OSCC patients diagnosed in Queensland, Australia, the authors of this paper re-analysed patient cohort data to determine the cause of death. Overall, 5,859 patients died: 3,585 (61.2%) from a cancer related episode in the head and neck, 796 (13.6%) from cancer outside the head and neck region, and 1,478 (25.2%) from a non-cancer related cause. Improved understanding of the cause of death offers important opportunities to enhance contemporary care provision, including more accurate prediction of mortality outcomes, recognition of patients whose pre-existent comorbidities limit the efficacy of intensified treatment modalities, and the delivery of better post-treatment screening and tertiary preventive strategies.

Published: September 2023

A dental screening service for children deemed at risk of developing infective endocarditis was developed by the paediatric dental team at St Thomas’ Hospital in London. The dental team attended outpatient cardiac clinics to undertake dental screenings while providing appropriate preventive advice and (if necessary) referral for specialist dental treatment, in compliance with Congenital Heart Disease Standards and Specifications. A total of 288 patients had dental screenings over an 18-month period. The patients and parents were shown to have insufficient knowledge regarding oral health, and were recommended oral health habits. Around 10% of patients required referral for urgent treatment in the paediatric dental centre.
Recruitment and retention in the dental workforce: the benefits of a strengths-based approach
Authors: Fox Kathryn , Burke Julie
Published: September 2023

The NHS is facing a crisis in recruitment and retention of dental professionals. In order to tackle this problem, we need to explore new avenues. One evidence-based approach is strengths-based recruitment (SBR), in which employees’ natural talents and strengths are matched to particular roles. This has been shown to improve not only employee retention but also engagement, wellbeing and job satisfaction. This paper presents, for the first time, the concepts and benefits of SBR in relation to dentistry.
Hanamichi und Mie-Pose: Modern imprägnierte Versatzstücke des japanischen Kabuki in Max Reinhardts frühen Bühnenmodellen und Inszenierungskonzepten
Authors: Haitzinger Nicole
Published: September 2023

Abstract: Dieser Artikel skizziert im ersten Teil die Wiener Theaterkultur in der zweiten Hälfte des 19. Jahrhunderts mit Akzentuierung des Japonismus, in der Max Reinhardt (1873–1943) sozialisiert wurde. Diese von der Forschung meist nur als Randnotiz erwähnte strukturelle und ästhetische Gebundenheit Reinhardts an die Wiener Moderne scheint mir entscheidend für das Verständnis seiner ersten Bühnenmodelle und Inszenierungskonzepte zu sein. Die Analyse der Inszenierung Sumûrun (1905) dient im zweiten Teil schließlich zu thesengeleiteten Antworten auf die Frage, welche spezifische Funktion die aus dem japanischen Kabuki entlehnten Versatzstücke Hanamichi (Blumensteg) und die Mie-Pose hatten und welche ästhetische Erfahrung sie evozierten.
Choreographien in/der Distanz. Affizierung im Transit
Authors: Schneider Katja
Published: September 2023

Abstract: Durch die Covid-19-Pandemie gerieten Konzepte von Nähe und Distanz im Spannungsfeld von Körper, Ökologie und Atmosphäre ebenso auf neue Weise ins Blickfeld wie partizipative und interventionistische choreographische Projekte. Indem in der Pandemie die Nutzung des städtischen Raums für die Bewohner*innen reduziert wurde, beeinflusste dies auf gravierende Weise speziell solche choreographischen Projekte, die etablierte Raumwahrnehmungen durchkreuzen, den Modus von Räumen verändern und zugleich die ordnenden Kräfte solcher Räume deutlich machen wollten. Am Beispiel von zwei Produktionen – trajectory – pictures of the fleeting world des Münchner Choreographen Micha Purucker sowie Zerstreuung überall! Ein internationales Radioballett der Gruppe Ligna – konturiert der Beitrag, wie sich Projekte im Kontext der Pandemie auf je besondere kinästhetische und atmosphärische Weise im öffentlichen Raum situieren. Außerdem fragt er danach, welche Affizierungsstrategien mit Bruno Latours Wo bin ich? Lektionen aus dem Lockdown (2021) korrespondieren.
Agora abbauen. Theater als metökische Konstellation
Authors: Stenzel Julia
Published: September 2023

Abstract: Der Beitrag unternimmt eine dekonstruktive Lektüre von ‚Agora' als eines Grundbegriffs politischer Theorie und politischen Theaters. Statt als exklusiver Raum politischer Repräsentation wird ‚Agora' so als Sammelplatz beschreibbar, an dem Weisen und Akteur*innen des Zusammenlebens immer wieder neu in Frage stehen. In der Relektüre von ‚Agora' wird ausgehend von einer ‚environmental performance' der iranischen Theatermacherin Azadeh Ganjeh, Unpermitted Whispers , ein Konzept der metökischen Konstellation als einer theatralen Strategie zur Pluralisierung der Agora entwickelt. Es folgt eine Untersuchung des in Essen-Stoppenberg situierten Solorollenspiels Achtmal Blinzeln (Anna Kpok), die die Räume des Spiels mit einem Modell von Agora als Ort des Handels, des Handelns und des Aushandelns von Szenologien des Erscheinens, des Sprechens und der Repräsentation konfrontiert. Der Ansatz tritt entsprechend in Dialog mit Theater und Performance, die über Erscheinungsräume nachdenken; über deren Diskursethiken, institutionelle Ästhetiken und ihre materialen Verortungen in der Stadt; mithin auch über (Un)Möglichkeiten von Demokratie.

Authors: Sauro Clare
Published: September 2023

Ann Duskin Lincoln, the founder of the Philadelphia specialty shop Nan Duskin, dominated Philadelphia retail for decades and played a significant role in the development of American fashion. At its peak, Nan Duskin was one of the leaders of American retail, and its founder, Mrs Lincoln, was internationally recognized for her fashion instincts and was one of the most respected, feared, and loved retailers in the business. This article will focus on Mrs Lincoln and Nan Duskin from 1927 to 1965, a transformative period for American fashion. It will explore the unique social role of the women’s specialty shop in American retail during the first half of the twentieth century and the critical role they had in the promotion and development of American fashion. Exemplary in every aspect, Mrs Lincoln’s career is representative of the many independent female retailers that flourished in the first half of the twentieth century.
Lansia di era bonus demografi
Authors: Cicih Lilis Heri Mis , Agung Darojad N.
Published: September 2023

Currently, the demographic dividend era is in progress, but improving the quality of competitive human resources is still a challenging process. Human capital investment needs to be implemented to make the older person healthier, independent, prosperous and dignified in the future to reach the second demographic dividend. This study provides an overview of the older person and province characteristics in the era of the demographic bonus. The data sources are the 2019 National Socio-Economic Survey (Susenas) and other official publications. The analysis was carried out descriptively on a provincial scale for individuals aged 60 years or over. The results showed a dependency ratio below 50 (namely demographic bonus), but several provinces still needed to decrease fertility and mortality. Based on the older person's current condition, most still have low access to income, education, health services, and communication technology. Various efforts need to be implemented in collaboration between the government and other stakeholders to enhance the better quality of the older person in the next future. It is necessary to provide people with job opportunities, knowledge, and health and financial security skills to prepare for old age.

Authors: Nugrahaeni Shafira Ramadhani , Sugiharti Lilik
Published: September 2023

This study aims to analyze the effect of demographic factors (child mortality, age of first marriage, type of contraception) and non-demographic factors (economic factors represented by income; social factors consisting of mother’s education and work status; and cultural factors represented by ethnicity and religion) on fertility in Indonesia. By applying Ordinary Least Square (OLS) method, this study uses cross-sectional data from Indonesia Family Life Survey Wave 5 in 2014. OLS regression results show that demographic factors that influencing fertility in Indonesia are child mortality, age of first marriage, and type of contraception (IUD and tubectomy). Meanwhile, non-demographic factors that have an effect on fertility in Indonesia are income and mother’s education. Moreover, the significant effect of cultural factor on fertility in Indonesia is only shown partially among ethnic groups.
Elemen kunci pendorong partisipasi masyarakat sebagai fondasi kebijakan Smart City: Suatu kajian pustaka sistematis
Authors: Darmawan Adriansyah Dhani
Published: September 2023

This study aims to identify critical elements needed to enhance community participation in Smart City policies. Although several studies have discussed the role of citizens in smart cities, these studies focused only on one aspect, whether it was the societal aspect, government/municipality, or technology. In order to fill the gap in the literature, this study seeks to extract the important elements of citizen participation based on the three aspects as a whole by using the systematic literature review (SLR) method. The SLR method is useful for mapping comprehensively when information or knowledge about a particular topic is being developed with limited empirical evidence. A total of 103 articles published from 1999-2021 were analyzed as the unit of analysis for this study. There are 12 critical elements to encourage community participation, and all these elements should not be considered partially. This study argues that it is essential to synchronize each element to make substantive participation. By doing so, the community will have the opportunity to make a transformative impact on smart city development.

This study aims to determine factors influencing outpatient treatment of elderly population in East Java Province. The analysis used raw data of the 2017 National Socio-Economic Survey (Susenas) conducted by Statistics Indonesia. The unit of analysis is population aged 60 years and over, with a total sample of 6,511 persons. Multilevel binary logistic regression model was employed for the analysis. The results showed that nearly half (49.6%) of the unwell elderly population did not seek treatment. The reasons for this behaviour include they did not have enough money (especially in rural areas), chose to self-medicate, and felt no need for treatment. For the elderly who seek outpatient treatment, the most visited health facility is doctor or midwife practice. The results also show that factors affecting the behavior of elderly population in outpatient treatment are economic status, working status, activity disruption, and health insurance ownership.

Effect of the 40-PPI copper foam layer height on the solar cooker performance
Authors: Shbailat Suhaib J. , Rasheed Raghad Majeed , Muhi Rahim J. , Mohammed Akeel Abdullah
Published: September 2023

Two box-type solar cooker (BTSC) prototypes were tested to examine thermal performance under identical conditions. The first box solar cooker used an absorber plate fabricated from copper, and the second box solar cooker used 40 pores per inch (PPI) of copper foam sheets. Many experiments on solar cookers were carried out in September 2022 in Baghdad, Iraq, where the solar cookers were directed to the south and situated at latitude 33.3°N and longitude 44.4°E. In the experimental testing, copper metal foam 40 PPI is used as a heat absorber plate at various absorber plate heights (1, 3, 5, and 7 cm). The results showed that the solar cooker with a 40 PPI copper foam absorber experienced a stagnation temperature of roughly 17° higher compared to a BTSC with a standard absorber. A copper foam 40 PPI absorber plate can reduce cooking time in a BTSC by as much as 23% compared to a standard flat absorber plate. The percentage of increase in the solar cooker’s internal temperature with an increase in absorber plate height from 1 to 7 cm for 40 PPI copper foam absorber plate is approximately 16.1%. The acceptable range for the equation of cooking power indicates that the cooker can be relied upon for consistently cooking food and boiling water.
Vom Wert der Wissenschaft. Die Psychologin Brigitte Schliebe-Lippert und die Neuorganisation
der hessischen Lehrerbildung, ca. 1946–1952
Authors: Schlicht Laurens
Published: September 2023

Der Aufsatz untersucht anhand des hessischen Kultusministeriums, wie in der unmittelbaren Nachkriegszeit (ca. 1946–1951) versucht wurde, durch Lehrerbildung neue demokratische Werte zu etablieren und zu vermitteln. Hierzu verfolgt er die Bemühungen der Psychologin Brigitte Schliebe-Lippert (1898–1993), die von 1946 bis zu ihrer Pensionierung im Jahr 1963 das Referat Lehrerbildung im hessischen Kultusministerium leitete. Schliebe-Lippert ist einerseits als Frau in einer ministerialen Leitungsposition eine Ausnahmeerscheinung. Andererseits ist sie als in Gießen im Jahr 1932 habilitierte Psychologin Teil einer frühen und kleinen Gruppe von habilitierten Frauen. Sie vertrat in der Nachkriegszeit die These, dass die Bemühungen um Reeducation seitens der amerikanischen Militärregierung vor allem auf der Basis einer wissenschaftlichen Psychologie zu unterstützen seien. Vorliegender Aufsatz fragt danach, in welchem Modus der Zusammenarbeit mit den amerikanischen Militärbehörden Schliebe-Lippert versuchte, ihre Version der Entwicklungspsychologie zu platzieren. Es wird überdies untersucht, inwiefern Wissenschaftlichkeit im Allgemeinen und sozial- und humanwissenschaftliche Wissenschaften wie die Psychologie im Besonderen in den Augen der Akteur:innen Grundlagen waren, auf denen neue demokratische Werte begründet werden konnten. Dabei werden die Positionen Schliebe-Lipperts im Kontext der deutschen Diskussionen über Lehrerbildung und vor dem Hintergrund ihrer Aktivitäten während des Nationalsozialismus kontextualisiert. Der Beitrag stützt sich auf den Nachlass Schliebe-Lipperts und Überlieferung zur Lehrerbildung im Hessischen Hauptstaatsarchiv, weitere Archivquellen in Frankfurt und Mainz sowie publizierte Texte.
Image Processing Algorithm Design of Agricultural Internet of Things Platform Based on Big Data Analysis
Authors: Sun Han
Published: September 2023

To solve the problems of low signal to noise ratio (SNR), poor processing effect, and long processing times for traditional image processing algorithms, an image processing algorithm for the agricultural Internet of Things platform based on big data analysis was designed. The big data analysis method was used for agricultural low-quality image recognition, and the Internet of Things platform uses sparse representation and a complete dictionary of low-quality image denoising processing with an improved histogram equalization method to enhance the image denoising result and get a high-quality image. Through this, the image processing algorithm design of the agricultural Internet of Things platform was completed. Experimental results show that the algorithm has high SNR and a good image processing effect, and the image processing time is always below 0.7 s, which meets research expectations.
Spatial and temporal analysis of drought-related climate indices for Hungary for 1971–2100
Authors: Kis Anna , Szabó Péter , Pongrácz Rita
Published: September 2023

The lack of precipitation may cause severe damage in different sectors, especially in agriculture and forestry, therefore, its analysis is a key element of adaptation strategies in the changing climate. In the present study, we selected different climate indices as important indicators for forests to investigate the current and future wet and dry conditions in summer in Hungary. For the historical period (from 1971), the observation-based HuClim dataset is used, which already shows a slight drying trend in the past 50 years, especially in June. For the future, regional climate model simulations from the EURO-CORDEX program are used, taking into account two different RCP scenarios (a business-as-usual scenario and an intermediate mitigation scenario, i.e., RCP8.5 and RCP4.5, respectively). Since mitigation starts to affect the climate system after about 20 years, results do not differ substantially for the two scenarios until 2060, however, the simulated changes highly depend on the applied RCP scenario in the late 21st century. Based on the De Martonne Index, a large expansion of semi-arid conditions is projected for the future in July and even more in August. The analysis of the Forestry Aridity Index shows that the steppe category will become dominant in 2081–2100, while the category optimal for beech may disappear entirely from Hungary according to the RCP8.5 scenario.
From geopolitical fault-line to frontline city: changing attitudes to memory politics in Kharkiv under the Russo-Ukrainian war
Authors: Gnatiuk Oleksiy , Homanyuk Mykola
Published: September 2023

The article investigates changing attitudes to memory politics in Ukrainian city of Kharkiv. In February 2022, with the outbreak of the full-scale Russo-Ukrainian war, this geopolitical fault-line city became a frontline city with significant potential outcomes for urban identity and local geopolitical preferences, including attitudes to the national memory politics. The research is based on the comparative analysis of the two surveys among residents of Kharkiv, conducted in spring-summer 2018 and in autumn 2022 – before and after the full-scale war. The results of the surveys are analysed by means of descriptive statistics and binary logistic regression. Additionally, two focus groups were held in order to receive additional justification when interpreting the results of the survey. The research shows that the attitudes to Ukrainian nation-centric memory narrative, including both decommunisation and decolonisation, have significantly improved. Nevertheless, public attitudes to the memory politics in the frontline city are highly reflexive in nature and deeply embedded in the context of the ongoing war. The geopolitical divide, which existed before the war, has largely transformed into a cultural one, namely heterogeneity of attitudes to the Russian cultural heritage in the city. This softened albeit still existing divide has, to some extent, materialised in physical space and runs between the ardent supporters of decommunisation and decolonisation that massively fled from the atrocities of the war and their opponents who at most choose (or were obliged) to stay in the front-line city. The study reveals that military conflicts may either activate hidden geopolitical divides in geopolitical fault-line cities or contribute to their transformation or even disappearance.
CONSTRUINDO UM DEBATE ACERCA DE EDUCAÇÃO ANTIRRACISTA E ANTISSEXISTA, A PARTIR DO PENSAMENTO SOCIAL DE SUELI CARNEIRO
Authors: Silva dos Santos Mayra , Barreto Oriente Silvana
Published: September 2023

A intenção desse trabalho é trazer discussões em torno do pensamento intelectual e ativista de Sueli Carneiro, na busca por uma educação que promova a luta contra a discriminação, preconceito e as diversas formas de violência contra qualquer gênero e raça. A partir daí, abordar as contribuições do seu pensamento social para uma educação antirracista e antissexista. Ressaltando nesse caminho, que seus estudos e pesquisas se constituíram como marcos históricos na consolidação do pensamento feminismo negro no Brasil. Realizamos um levantamento bibliográfico das obras de Sueli Carneiro (1985; 2003; 2011; 2013; 2020) e, posteriormente, uma análise crítica-argumentativa de suas produções na perspectiva educacional. Utilizamos a perspectiva Freiriana de uma educação para a liberdade e para os Direitos Humanos, como forma de discutir, refletir e propor alternativas para uma processo educativo mais igualitário, equânime e plural, discutidas na obra de Freire (2001). Ressalta-se que o pensamento de Sueli Carneiro nos possibilita pensar as contribuições do feminismo negro na luta antirracista e antissexista, que por muito tempo condenou mulheres, sobretudo mulheres negras a uma situação perversa de crueldade, exclusão e marginalização social.
AS TRÊS UTOPIAS EDUCACIONAIS NA OBRA DE MARIA LACERDA DE MOURA
Authors: Lessa Patrícia
Published: September 2023

Maria Lacerda de Moura foi uma educadora normalista que participou em várias frentes de trabalho escolar e viu nas teorias pedagógicas libertárias uma forma de escapar dos métodos tradicionais amparados no binômio prêmio-castigo. Para os grupos e as pessoas envolvidas com o anarquismo, a educação possuía um lugar central, tendo em vista que proporcionava uma crítica ao ensino burguês e religioso e, por outro lado, materializava sua própria concepção pedagógica através da criação de escolas autônomas e autogeridas, livres da igreja e do Estado, bem como a produção de seus próprios materiais escritos, fundamentados em princípios de autonomia, de autogestão, de internacionalização e de ação direta. A coeducação de gêneros e de classes era vista como forma de trocas e como um recurso para o desenvolvimento das crianças e dos jovens. Não havia separação hierárquica entre o trabalho manual e intelectual, ambos deveriam servir como ferramentas para o aprendizado. Nesta reflexão, apresentamos algumas das ideias da autora sobre a Educação expostas em livros, partimos de um debate proposto por Miriam Moreira Leite a respeito das utopias educacionais na obra de Maria Lacerda. As utopias educacionais dela coincidem com suas mudanças nas redes de contatos e aparecem em seus escritos. As teorias anarquistas tinham sólidas propostas sociais e culturais. O encontro e a amizade da educadora com Fábio Luz e José Oiticica possibilitou o estudo sobre as experiências pedagógicas de Paul Robin, Sébastien Faure e Francisco Ferrer y Guardia. A crítica aos modelos adotados na escola oficial brasileira e as novidades educacionais trazidas da Europa fizeram eco ao pensamento dela, que pôde escrever e pronunciar palestras sobre um novo modelo educativo, pautado no respeito à criança, bem como nas diferenças de classe, etnia ou gênero.
UM ESTUDO SOBRE FEMINISMOS E ATUAÇÃO DE MULHERES EM SINDICATOS DA EDUCAÇÃO
Authors: Ondina Vieira Ferreira Márcia
Published: September 2023

Inserindo-se na perspectiva das investigações que articulam gênero e desigualdades sociais, este trabalho quer se centrar na percepção que, sobre este tema, apresentam feministas atuantes em sindicatos do campo da educação. Considera-se recente uma apropriação maior dos temas relativos a gênero por parte de sindicalistas, independentemente do sexo. Ser mulher sindicalista não garante conhecimentos sobre gênero nem convencimento de sua importância crucial nas relações de poder social: as percepções dos indivíduos são influenciadas mais diretamente por seus valores pessoais, discutidos e apropriados (ou não) por seu grupo político ou corrente sindical. Entretanto, as sindicalistas informantes deste estudo não apenas reconhecem a importância da categoria gênero, como a usam cotidianamente para interpretar processos sociais, inclusive considerando, a si mesmas, feministas. Neste sentido, se ainda não é uniforme a ideia de levar adiante lutas em relação a gênero entre direções sindicais, o que caracterizaria as mulheres que, sim, defendem essa pauta de ação e, além disso, identificam-se como feministas? Nossas informantes são cinco sindicalistas renomadas no âmbito da Confederação Nacional de Trabalhadores em Educação – CNTE, organização formada por 52 sindicatos da educação básica pública brasileira. A partir de entrevistas, foram abordados os seguintes aspectos: suas trajetórias políticas; o processo pelo qual se tornaram feministas e que concepções têm sobre os feminismos; como ocorrem as articulações entre mulheres feministas e sobre o que elas atuam. Os resultados da análise, em termos de empoderamento feminino, são dois. Primeiro, a importância da sororidade para formar novos quadros – o empoderamento é algo que se produz coletivamente; segundo, a importância das cotas para exercitar a construção cultural de que as mulheres também podem ser dirigentes. Ademais, em termos de concepção de feminismo, as mulheres parecem indicar características próximas as do feminismo radical, passando pelo socialista e chegando à concepção interseccional.
Effects of storage temperature and pre-treatments on seed germination of Primula mallophylla and P. sertulum (Primulaceae), two narrowly-distributed endemic species from southwest China
Authors: Tian M.H. , Tang A.J.
Published: September 2023

Primula mallophylla and P. sertulum are wild ornamental species of south-west China, but the responses of their seeds to storage have not been determined. When seeds were dry-stored for 24 months at room temperature (RT) (ca. 21°C) and at 4°C, germination increased
during the first six months, but then decreased over the following 18 months. The decrease in germination was slower for seeds stored at 4°C than for those stored at RT. When seeds of these two species were dry-stored at -20°C for 24 months, germination percentage was significantly
higher than that of the control seeds by the sixth month; the high germination percentages persisted at 24 months. In addition, pre-germination treatments (i.e., immersion in 100 μmol L -1 GA3 for 24 hours, cold stratification for 30 days or both) improved the final germination
and reduced mean germination time of P. mallophylla seeds stored for 12 months at RT, but not those of P. sertulum. Taken together, storing seeds at -20°C is feasible and convenient for both primrose species; thus, it is possible to safely store seeds for future research
and conservation.

Published: September 2023

Thyroid cancer (TC) represents the most common endocrine malignant tumor. Liquid biopsy has been suggested as a new and accurate biomarker in cancer. This systematic review analyzes the existing literature on circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), cell-free DNA integrity index (cfDI), and their potential as biomarkers for TC, including the subtypes: differentiated (papillary and follicular), medullary, and anaplastic. A systematic search was performed in PubMed, Embase, and Cochrane databases for published articles in English between 1 January 1970 and 6 September 2022 (PROSPERO: CRD42022358592). The literature search generated a total of 635 articles. In total, 36 articles were included (patients = 2566). Four studies reported that higher levels of CTCs were associated with metastases and worse prognosis. Nineteen studies found the presence of mutated ctDNA in TC patients. The diagnostic accuracy in detecting BRAFV600E as ctDNA was determined in 11 studies regarding papillary TC. The pooled sensitivity, specificity, and diagnostic odds ratio were estimated at 56% (95% CI 36–74), 91% (95% CI 84–95) and 12 (95% CI 4.09–33.11), respectively. Four studies concluded that the cfDI was higher in patients with TC compared to benign thyroid lesions and healthy controls. The detection of CTCs, ctDNA, and cfDI may have a potential prognostic value in TC in relation to diagnosis, disease progression, and treatment efficacy. Despite the promising potential of CTCs, ctDNA, and cfDI in TC management, limitations hinder direct comparison and generalization of findings. Standardized methodologies, larger patient cohorts, and a consensus on relevant markers are needed to validate their clinical applicability and enhance TC management.

In August 2017, Heilongjiang Province was affected by the weakening of the typhoon HAITANG, which turned into a low-pressure system northward, causing a heavy rainstorm. The data used in this paper was obtained from the 2.5°×2.5°NCEP reanalysis dataset, conventional observation data and FY-2C2D satellite images. Starting from the large-scale circulation situation, analyze the physical mechanism of the heavy rain in Heilongjiang Province and the characteristics of satellite images. The results show that typhoon HAITANG degenerates into a low pressure system that carries lots of warm and humid air northward, which is combined with the cold air in the north. Heilongjiang Province is affected by the interaction of warm and cold air. The large value area of water vapor convergence overlaps with the center of pressure and moves northeast with it. At the same time, the water vapor convergence gradient is relatively large, which is a good corresponding relationship with the appearance of heavy rainfall areas. The low-level convergent and high-level divergent circulation conditions are conducive to the maintenance of low-level ascending movement and provide favorable conditions for the occurrence of heavy rainstorms. Heavy rainstorms mainly occur in areas where the cloud system is thicker and densely structured, where the upward movement is relatively strong.
Students’ Models of Magnetic Interactions: A Comparative Analysis of Accurate and Inaccurate Models over a Ten-Year Interval
Authors: Yuksel Tugba , Bryan Lynn A.
Published: September 2023

This research investigates the Models of eighth-grade students in Turkey pertaining to magnets and magnetic interactions, while also examining the consistency of these models within themselves. Additionally, a comparative assessment is conducted by comparing the current data with data collected from eighth-grade students a decade earlier. The study comprises 59 students in the first phase and 45 students in the second phase, all of whom briefly received formal instruction on magnetism during fourth grade. The focus of the analysis centers on identifying the students’ Models and evaluating their coherence across diverse contexts in both phases. Surprisingly, despite the passage of ten years, the mental model patterns exhibited by the students in both studies remain remarkably similar. Three primary categories emerged from the students’ Models of magnets, including attraction and repulsion, magnetic poles, and the composition and functionality of magnets. However, noticeable distinctions between the two studies are evident. In the earlier study, the students’ responses to survey questions displayed a greater variety and detail in comparison to the responses from the later study. Moreover, the second study revealed fewer instances of inconsistent Models concerning the magnetic interaction between magnets and nails, but more instances of inaccurate Models compared to the first study. The findings of this investigation offer valuable insights to educators, guiding them in designing effective lessons and activities aimed at helping students overcome their inaccurate and inconsistent Models.

Published: September 2023

Flame retardancy was induced in maple (Acer velutinum) and ash (Fraxinus excelsior) wood and bark by means of mixtures consisting of bio-based materials such as starch (S) and glue (G) and water-based paint, MINWAX (M) in two different combined formulations with perlite (P) as the main fire retardant. The selected wood species as solid wood with two different treatable surfaces (with and without bark) were examined. The lowest and the highest mass loss occurred in the untreated-ash and untreated-maple wood samples with bark, while the lowest weight percent gain was related to PSGM-treated ash wood samples with bark, and the highest weight percent gain was related to PSGM-treated maple wood samples without bark. The lowest time to ignition and glowing point time were measured in the untreated-maple wood samples without bark, and the highest of them were measured in the PSGM-treated ash wood samples without bark. The effect of bark in the treated- and untreated-maple samples on the time to ignition and glowing point time was greater than the bark of treated- and untreated-ash samples, respectively. There was not any significant relationship between actual retention, weight percent gain, and mass loss for all treatments. However, there was significant difference between the individual and interaction agents on fire retardancy of treated and untreated samples.

Cellulose nanocrystals (CNCs) with a high content of polar groups were prepared via the oxidation process by controlling the amount of mixed acid, incorporating additional additive of citric acid and vitamin C as active agents, and applying ultrasonic crosslinking. Subsequently, cellulose nanocrystal–silver (CNC–Ag) nanohybrid materials were synthesized via an oxidation hydrolysis reaction, which displayed good dispersibility and high interaction, leading to the hydrogen bonding between polar groups (-OH and -COOH) on the surface of CAC–Ag nanohybrids. The positive effects of hydrogen bonding on the surface of CAC–Ag nanohybrids were confirmed by the high carboxyl group content (2.69 mmol/g) and low contact angle (53.7°) tested. In addition, CAC–Ag nanohybrids showed significant antibacterial activity against both Gram-negative E. coli and Gram-positive S. aureus. These results showed that the high-performance CNC–Ag nanohybrids prepared in this study may be highly suitable as nano-fillers for polyester materials used in antibacterial food packaging.

Based on regional geology, Tanjung Palas Timur Subdistrict is included in the only formation, which includes coal seams. The depletion of oil and gas energy sources in Indonesia results in the need for other alternative energy sources, one of which is coal. This study aims to determine the characteristics of coal in the study area. This research was conducted in Tanjung Palas Timur Subdistrict, North Kalimantan using the geoelectric resistivity method with a pole-pole configuration and 8 tracks which are divided into 2 track blocks. The resistivity geoelectric method is used because it is very suitable for mining exploration. Data processing was done in 2D using Res2dinv software and 3D using Rockworks15 software. The results of the geoelectric data processing of line 1 to 8 show that the coal seam in the study area has a resistivity of 10-30 Ωm with a thickness varying from 17.22 m - 60 m as a type of lignite coal. In addition, the research area is also dominated by layers of clay and sandstones. The continuity of the coal seam is also seen in block 1 from line 3 in the southwest direction to line 1 in the northeast direction.

This research succeeded in modifying the manufacture of gypsum board with the addition of natural fiber, namely bintaro fruit with the 3D orientation arrangement method. The raw materials for this research are gypsum flour and Bintaro fruit fiber as a matrix and filler. Bintaro fruit fiber previously carried out an alkalization process where the fiber was soaked in a solution of NaOH and distilled water for 24 hours. The manufacture of composites using the ratio of the matrix mass fraction and the filler mass fraction is as follows 100: 0, 99: 1, 98: 2 and 97: 3. The characterizations carried out include density test, moisture content test, flexural strength test and micromechanical analysis. Gypsum board composite based on micromechanical calculations resulted in the highest density value in the control sample, in the best density value was at the filler fraction of 3%, the best moisture content value in the control sample, the flexural strength test value the best of the control sample, but the filler fraction is 3% of the sample with the best fracture resistance. 3D orientation in theory and practice has fulfilled the principle that it is able to increase the physical and mechanical value of gypsum board.
