Abstract
Structured beams carrying orbital angular momentum (OAM) provide powerful capabilities for applications in optical tweezers, super-resolution imaging, quantum optics, and ad-vanced microparticle manipulation. However, it is challenging for generate and control the OAM beams at the extreme ultraviolet (EUV) region due to the lack of suitable wave front shaping optics arise from being limited to the strong absorption of most materials. Here, we use a modified Fermat-spiral photon-sieve splitter to simultaneously generate two focused doughnut beams with opposite helical phase. Our technique enables us to produce splitting focused vortex beams with different rotation directions at EUV wavelengths. Additionally, we provide experimental evidence showcasing the capabilities of our method and further detect the helical phase by self-reference interferometry. This work not only opens a route for OAM-driven applications in EUV radiation, but also paves the way to studies of holographic technique by EUV splitter.

Published: September 2024

In the present work, we investigated the influence of the toxic vapors (ammonia, chloroform, tetrahydrofuran, dimethylformamide, nitrobenzene, toluene) on the specific resistance, optical absorption, and structure of conducting polymer poly-o-toluidine (PoT) obtained by oxidative polymerization of o-toluidine in toluene sulfonic acid (TSA) solution. This polymer has a high level of crystallinity and is thermal stable to 473 K (200 0C). The action of organic solvent vapors causes an increase in PoT-TSA resistance by 1.3-1.4 times, while after the action of ammonia, the resistivity increases almost 500 times. The activation energy of charge transfer Ea also increases from 0.21 to 0.71 eV under the action of ammonia due to the deprotonation of the polymer and its transformation to the resistive base form. When the organic solvents are used, the observed phenomena have a different direction (resistance increase or decrease) due to the peculiarities of polymer-solvent molecular interaction. This phenomenon may be used for selective detection of solvents.

Authors: Dobosi Linda , Szabadváry Tamás 
Published: September 2024

AbstractThere are six antefixes and an antefix mould from Roman Brigetio (Komárom-Szőny, Hungary) in the collection of the Hungarian National Museum, which are the first antefixes to be published from Brigetio. All made in the form of tragic masks with desperate expressions, they can be classified into two types based on their appearance. The only Type 1 antefix is characterized by straight, stylized hair and high onkos, with close parallels in Aquincum. The other five antefixes belong to Type 2 and were made in the same mould. These feature a male head with open mouth and wavy, shoulder-length hear with what appears to be a topknot. The mould fragment was the negative form of the Type 2 antefixes. Type 2 antefixes made in Brigetio were also found in the Roman villa of Ravazd.

Published: September 2024

Aim. To study the features of civic consciousness among modern university students.Material and methods. A total of 467 students took part in the study. The original author’s questionnaire was used (I. V. Koltsova, 2024), aimed at identifying the characteristics of students’ civic consciousness.Results. The study showed that the majority of students believe that secondary schools should take an active part in the development of civic consciousness of young people. Students behave in society in accordance with generally accepted rules, know the history of the Russian Federation, its traditions and customs, conspicuous figures, rights and responsibilities, speak their native language and actively use it in communication with representatives of their nationality. After training, most graduates plan to stay and work in the Russian Federation. However, about 30% of subjects have low scores on such issues as participation in the Russian presidential and legislative elections. There is a high awareness on socio-political events and laws, which indicates the low social activity of this group of respondents.Conclusion. The conducted research made it possible to identify both positive trends in relation to the civic consciousness of students, as well as problem areas that require targeted educational work.

O Uso das TDIC nas Vivências de Professores de LE no Ensino Remoto (2020 e 2021) na Cidade de Macapá-AP
Authors: Amoras Aluana Vilhena , Paixão Eliana do Socorro de Brito 
Published: September 2024

A pandemia de Covid-19 afetou o desenvolvimento e a realização tradicional das atividades educacionais. Uma medida adotada pelas instituições públicas amapaenses, para propiciar a continuidade do processo de ensino-aprendizagem formal, foi a prática do ensino remoto em todas as disciplinas do currículo escolar. Como as disciplinas de Línguas Estrangeiras (LE) precisam de um formato de ensino que contemplasse as competências de comunicação de compreensão oral e escrita, produção oral e escrita, no ensino remoto, necessitaram de adequações e uso de tecnologias diferenciadas, apesar dos poucos domínios quanto à utilização. Assim, a pesquisa objetivou analisar as vivências de professores de LE no ensino remoto, durante o período pandêmico (2020 e 2021), em Macapá-AP, com foco do uso de tecnologias digitais. A metodologia adotada teve o suporte do método hermenêutico (Hermann, 2002), de abordagem qualitativa. O instrumento de coleta de dados foi o questionário semiestruturado com questões acerca da experiência vivenciada por sete professoras das disciplinas de LE de quatro escolas estaduais. Adotou-se técnicas da Análise de Conteúdo (Bardin, 2016) para tratamento e análise dos dados coletados. Dessa forma, constatou-se que, durante os anos de 2020 e 2021, em Macapá-AP, o processo de ensino-aprendizagem não foi interrompido, dando-se de forma remota, com o uso de metodologias diferenciadas e diversas TDIC como WhatsApp, plataformas de videoconferências, Google Forms, vídeos do Youtube e internet, identificadas nas práticas docentes dos professores de LE, que desenvolveram suas atividades pedagógicas com seus recursos pessoais, sem terem recebido suportes tecnológicos do Governo estadual.

Authors: Peinado Jurandir , Vianna Fernando Ressetti Pinheiro Marques , Meneghetti Francis Kanashiro 
Published: September 2024

A pandemia da Covid-19 obrigou organizações e governos a adotarem medidas de distanciamento social, tais como o deslocamento de atividades presenciais para o modelo remoto, mediado por Tecnologias de Informação e Comunicação (TIC). Contudo, o advento de vacinas e protocolos possibilitaram a diversos setores ― entre eles, o da educação ― o retorno ao modelo presencial, criando, assim, a demanda por pesquisas que investiguem esta situação, denominada “pós-pandemia”. Assim, o objetivo desse artigo foi identificar as percepções e expectativas dos estudantes de uma universidade pública brasileira frente ao retorno às aulas presenciais. Por meio de um questionário enviado aos universitários, o grupo de pesquisadores utilizou a técnica de análise de conteúdo para codificar e categorizar 987 respostas recebidas por meio de um Survey. Observou-se que as respostas dos alunos envolveram tanto aspectos diretamente ligados ao processo de ensino e aprendizagem (endógenos) quanto aspectos que tangenciam esse processo (exógenos).

Chemical Mechanism of Exogenous Jasmonic Acid-Induced Resistance in Rose Against Spodoptera exigua (Lepidoptera: Noctuidae)1
Authors: Chen Guiyan , Cheng Jing , Yang Zhuo , Zhao Qiuyu , Shao Zhangsong , Yang Fazhong , Li Yunxian 
Published: September 2024

Abstract
Jasmonic acid (JA) plays an important role in the indirect plant-mediated interactions between rose powdery mildew (Podosphaera pannosa [Wallr.: Fr.] de Bary) and Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) on their shared host Rosa chinensis Jacquin. Bioassays showed that the total number of eggs laid by S. exigua on rose twigs decreased significantly after the twigs were treated with exogenous JA. Gas chromatography coupled with mass spectrometry (GC-MS) showed that the volatile organic chemicals (VOCs) from roses, including alkanes, terpenes, aldehydes, ketones, alcohols, and esters, were significantly changed following treatment with JA. Based on gas chromatography-electroantennographic detection (GC-EAD) and GC-MS analysis, the electrophysiological responses of S. exigua moths could be elicited by 8 compounds from the JA-induced roses, including 3-carene, 1-dodecanol, methyl stearate, 1-tetradecanol, hexadecane, eucalyptol, β-myrcene, and 1-iodododecane. Among these chemicals, the first 6 exhibited significant repellent activity to ovipositional behaviors of the gravid moths, while the latter 2 were attractive. The inhibition index of methyl stearate at a concentration of 15 mg/ml reached 65.12%. On the other hand, the quantity of the first 6 chemicals increased significantly and the latter two decreased due to the JA induction. These results reveal a new mechanism for resistance in rose plants against S. exigua. After JA induction, the rose plants appear to up-regulate the biosynthesis of the chemicals with repellent activities against S. exigua and, in the meantime, down-regulate the attractant chemicals.

Authors: Andriatna Riki , Kurniawati Ira 
Published: September 2024

<p>Indefinite integrals are a fundamental concept in calculus. This qualitative study aims to describe the content of school mathematics textbooks on indefinite integrals. The analysis used the concept of praxeology, which includes theory, technology, and techniques, based on the Reference Epistemological Model. The primary instrument in this research was the researcher, who used data from school mathematics textbooks, including two electronic textbooks used in Indonesia, one textbook from Singapore, and one from the Cambridge curriculum. The study results included a Reference Epistemological Model for indefinite integrals, used to compare textbook content and praxeological components. Praxeological analysis shows that the theoretical and technological components of Indonesian school mathematics textbooks are more complex than those from Singapore and the Cambridge curriculum. These differences are attributed to variations in the mathematics curricula of the three regions. Therefore, the Reference Epistemological Model can guide the development of instructional materials on indefinite integrals, taking into account the complexity differences among the textbooks.</p><p> </p><p>Materi integral adalah salah satu konsep fundamental dalam kalkulus. Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk mendeskripsikan muatan pada buku teks matematika sekolah pada materi integral tak tentu.
