Noise Control of Blunt Flat-Plate Using Slit and Dielectric Barrier Discharge Plasma
Authors: Yan Xicai , Zhang Yaowen , Li Yong
Published: March 2024

This paper investigates the combination of a slit at the blunt trailing edge of the flat plate and dielectric barrier discharge plasma to control the vortex shedding of the plate and its associated tonal noise. The noise and flow characteristics of the plate were measured using a far-field microphone array and the particle image velocimetry technique, respectively. The results show that the vortex shedding and the tonal noise can be significantly suppressed by the slit alone, with an average noise reduction of approximately 10 dB in the test Reynolds number. In addition, installing a plasma actuator inside the slit further suppresses the vortex shedding and reduces tonal noise. However, the additional control efficiency of the plasma decreases with increasing wind speeds, with a further 8 dB reduction at a wind speed of [Formula: see text] (corresponding to an inducing blowing rate BR of 4.5%). However, only an additional 1.5 dB noise reduction is achieved at [Formula: see text] ([Formula: see text]). The particle image velocimetry snapshots were analyzed by proper orthogonal decomposition. The measurements clearly show the variation in vortex shedding at the trailing edge of the plate, revealing the underlying flow mechanisms that lead to the observed noise variations and frequency changes.
Экологическая этика в буддизме: традиции и современный опыт
Authors: Уланов Мерген Санджиевич , Бадмаев Валерий Николаевич , Хомутников Василий Хонгорович
Published: March 2024

Статья посвящена специфике экологической этики буддизма. В работе рассматривается  дискурс, связанный с феноменом экобуддизма, исследуется отношение к природе в традиционном буддизме, анализируется взгляд современных буддистов на экологическую проблематику,  рассматриваются буддийские экологические движения и организации, показана экологическая деятельность буддийского духовенства в России.
Источниковая база исследования разделена на две группы. К первой группе относятся древние буддийские тексты, содержащие элементы экологической этики. Ко второй группе источников можно отнести труды современных буддийских мыслителей. Многие современные буддологи и буддийские активисты считают, что буддизм обладает значительным потенциалом для решения современных экологических проблем. В их трудах можно обнаружить появление нового теоретического измерения буддийской традиции — экобуддизма. Существуют и более скептические точки зрения на данный вопрос. Критики экобуддизма подчеркивают, что традиционный буддизм служит в первую очередь сотериологической цели, и что попытка экологизации искажает исторические традиции и доктринальные установки. Однако, даже признание факта определённой реинтерпретации и модификации буддийского учения, не отменяет того факта, что идеи экобуддизма не противоречат духу и основным принципам буддийского мировоззрения. Анализ таких важных положений буддизма как учения о всеобщей взаимозависимости, карме, ненасилии и сострадании показывает, что они несут в себе серьезный экологический потенциал, что позволяет говорить о существовании буддийской экологической этики.
Сегодня многие буддисты принимают активное участие в борьбе за сохранение окружающей среды, опираясь на экологические установки буддийской традиции. Большой вклад в дело охраны окружающей среды вносят авторитетные буддийские лидеры, в частности, Его Святейшество Далай-лама XIV. Необходимо отметить и деятельность буддийского духовенства Бурятии, Калмыкии и Тувы, которое принимает участие в экологических акциях, а также ведет работу по формированию экологического сознания у местного населения.
Карл Шмюкле — неизвестный соратник по тувинскому путешествию Отто Менхен-Хельфена
Authors: Шафранская Элеонора Федоровна , Должикова Анжела Викторовна
Published: March 2024

Настоящей статьей в научный оборот вводится имя Карла Карловича Шмюкле, спутника Отто Менхен-Хельфена в путешествии в Туву 1929 года. Если о Менхен-Хельфене существует многообразная литература, начиная с его книги “Reise ins Asiatische Tuwa” (1931), то Шмюкле в истории ХХ века достался статус persona non grata.
Причина заключается в том, что он был арестован в 1937 г. и расстрелян в 1938 г. Авторство упоминаемой многими исследователями статьи, предшествовавшей кни­ге Менхен-Хельфена, о поездке в Туву, априори приписывалось Менхен-Хельфену. Где эта статья была напечатана, кто же ее автор, каково заглавие — эта информация отсутствует в научном дискурсе или дается с искажением. Приводится полностью информация об этой статье, ее полный текст; представляется ее автор К. К. Шмюкле; а также дается небольшой биографический очерк о нем.
gestión de las emociones
Authors: N. Fernández Claudia
Published: March 2024

La comedia de Aristófanes no presenta un modelo monolítico de heroísmo cómico; aun así, es posible detectar un número considerable de rasgos recurrentes en sus protagonistas – entre otros, un coraje admirable, responsable del agenciamiento del cambio social que la comedia normalmente procura en consonancia con los deseos de la audiencia. Este arrojo ejemplar se asienta en una total falta de temor (aphobίa) que el discurso se encarga de ensalzar en imágenes y metáforas de naturaleza bélica, en las que el protagonista queda asimilado a un bravo guerrero. En esa dirección, este trabajo se propone indagar acerca del rol del temor en los personajes de la comedia aristofánica cuyo protagonismo ha sido cuestionado o controvertido, como el caso de Agorácrito en Caballeros o Estrepsíades en Nubes. Asimismo, habida cuenta de que el temor es una emoción de inspiración política, y la comedia antigua se propone educar a su público políticamente, nos preguntaremos sobre el consejo que acerca del temor la comedia se propone brindar a su audiencia.

PENGARUH PENGUNGKAPAN AUDIT INTERNAL TERHADAP BIAYA AUDIT
Authors: Widiar RR. Wulan Indri , Faisal Faisal
Published: March 2024

This study examines the content of internal audit disclosures and their effect on audit fees. The sample consisted of 188 public companies listed on the Indonesia Stock Exchange in 2018. The analysis techniques used include content analysis, descriptive analysis and multiple regression analysis. The results showed that the mean disclosure of internal audit information is 56.99%. Information related to the existence of internal audit and internal audit structure are the items most disclosed by the entire company. Mean disclosures by sector show that property, real estate and building construction are the most disclosed sectors (60.93%). The results of the regression analysis show that internal audit disclosure has no effect on audit fees. However, if the disclosures are grouped under general and specific disclosures, specific internal audit disclosures have a negative effect on audit fees. As a result of these findings, specific internal audit disclosures may indicate that the firm being effectively monitored and controlled may be influencing audit fees.

Authors: Ghofananda Viva Nuralifiya , Mita Aria Farah
Published: March 2024

This research discusses the impact of the fair value method on fixed assets, audit fees, and audit committees in ASEAN. The samples of the research are 277 manufacturing companies listed in the Indonesia Stock Exchange, Malaysia Stock Exchange, Singapore Stock Exchange, Philippine Stock Exchange, and Thailand Stock Exchange from 2014 to 2016. The results of the study found that companies that use the fair value method through a revaluation model to measure their fixed assets have higher audit fees than those that use the historical cost method. In addition, there is a moderation effect of audit committee competencies on the relation of fair value method to audit fee. The findings prove that the accounting and financial competencies of the audit committees reduce audit fees imposed on companies using the fair value method for fixed assets.

δ-Bonding versus Electron Localization in Formally Divalent Rare Earth Complexes
Authors: MacKenzie Ross , Hajdu Tomáš , Seed John , Whitehead George , Adams Ralph , Chilton Nicholas , Collison David , McInnes Eric , Goodwin Conrad
Published: March 2024

Herein we present a series of room-temperature stable, structurally analogous rare-earth complexes of the form [M(NHAriPr6)2] (M = Sc, Y, La, Sm, Eu, Tm, Yb; NHAriPr6 = {N(H)C6H3-2,6-(C6H2-2,4,6-iPr3)2}). All seven complexes contain formal M(II) ions with close M···arene contacts. The Sc(II) and La(II) complexes display an open-book deformation (ca. 11–13°) of one metal-bound arene, while for Y(II) there are two symmetry-equivalent Y···arene interactions with smaller deformations (ca. 7°). In the case of Sc(II), Y(II), and La(II), quantum chemical calculations reveal the delocalization of a metal d-electron from M(II) into ligand π-orbitals forming δ-bonding interactions. In the case of Y(II), EPR and UV-Vis-NIR spectroscopies combined with quantum chemical calculations show a structural change in solution to the single-open-book deformation structure in common with Sc(II) and La(II). While the Sm(II), Eu(II), Tm(II), and Yb(II) complexes retain similar close M···arene contacts, their 4fn+1 valence electron configurations do not lead to δ-bonding interactions; however, NMR studies of diamagnetic 4f14 Yb(II) reveal 171Yb···1H coupling to arene ring-protons at room temperature and show that the M···arene interaction is preserved in solution across a wide temperature range. These complexes represent a rare structurally analogous M(II) series which extends from the group 3 elements into the lanthanide series and includes an extremely rare neutral formal Sc(II) complex.

Authors: M. M. Leal Allan , Tambach Tim , Volpatto Diego , Liang Xiaodong , Loldrup Fosbøl Philip , Thomsen Kaj
Published: March 2024

The extended UNIQUAC model is a thermodynamic model able to estimate thermodynamic properties of aqueous electrolyte solutions under a wide range of temperature, pressure, and composition conditions. Thermodynamic properties include species activity coefficients, excess molar Gibbs energy, excess molar enthalpy, excess molar heat capacity. These properties are important for aqueous speciation calculations, mineral and gas solubility computations, chemical kinetic modeling of mineral dissolution and precipitation, and in reactive transport simulations considering chemically complex aqueous electrolyte solutions. In this paper we present a brief literature review on the extended UNIQUAC model, we report on its im-plementation in C++ in the Reaktoro framework for modeling chemically reactive systems, and we show its use from Python for computing mineral and gas solubilities in aqueous solutions at a wide range of temperature, pressure, and salinity conditions. We validated the calculations against experimental data and against results obtained through the software ScaleCERE implementing the extended UNIQUAC model. Our conclusion is that the extended UNIQUAC model has been successfully implemented into the Reaktoro framework, thereby providing a suitable activity model for geochemical and reactive transport modeling.

Published: March 2024

The dental healthcare team treats a child in a pediatric clinic using a child management approach that is both effective and efficient. Managing children in a pediatric clinic requires a delicate balancing act between the child, the parent, and the dentist. It takes effective communication abilities to give dental treatment to youngsters. In addition to the well-known personality trait of anxiety, additional factors have also been discovered to contribute to the persistence of behavioral issues during dental procedures. It is often acknowledged that behavior management plays a crucial role in providing dental care for kids. It is undoubtedly difficult to deny a child the necessary dental care if their behavior in the office or dental clinic cannot be controlled.

Published: March 2024

Teachers are vital members of the community who devote their lives to developing skilled and productive individuals. Nonetheless, there are still arguments over teachers who do not use proper teaching techniques. It is also asserted that adverse school settings make it more difficult for them to carry out their jobs in an efficient manner. This study's objective was to assess the work commitment, school climate and productive pedagogical teaching practices of Islamic Education teachers (IETs). It also examined how work commitment and school climate relate to and affect IETs' instructional strategies. The study was quantitative in nature and employed a survey research design. A stratified random sampling procedure was used to select 454 IETs employed in Malaysian national secondary schools as the study sample. The study data was analysed using descriptive statistics along with inferential tools like Pearson correlation and multiple regression. The study's conclusions demonstrate that there is a high degree of work commitment, school climate, and IET teaching practices. Pearson's correlation test indicated that IET teaching practices positively influence both school climate and work commitment. The study's results also indicate that the teaching practices of IET are influenced by seven predictive elements. These results are important for the Malaysian Ministry of Education, in emphasising the necessity of in-service training to enhance commitment and proficiency among IETs and to create the supportive learning environment that is crucial to ensure that IETs can effectively fulfil their duties. Some suggestions for further research are also presented in this study.

Published: March 2024

This research explores the challenges of developing artificial intelligence (AI) at universities in China, India, and Indonesia for teacher education students. A qualitative research method was employed, with data collected through in-depth focus group discussions with 12 doctoral students from the 3 countries in equal proportions. The sample selection was based on the diversity of the participants’ relevant backgrounds, experiences, and understandings. The data collected were analyzed using a thematic approach involving the identification, mapping, and interpretation of themes. The research findings indicate variations in the main challenges in developing AI to improve the quality of teacher education in each country. In Indonesia, infrastructure and Internet access are the main constraints limiting the application of AI technology. Meanwhile, in India, the main concern relates to the lack of human resources skilled in the field of AI, prompting the need for relevant skills development among educators. Conversely, in China, the problem concerns striking a balance between utilizing advanced AI technologies, safeguarding privacy, and developing the capacity to accommodate rapid advances in technology-based education. The findings of this study provide valuable strategic insights, enabling the design of appropriate strategies in each country. The implications of the findings can assist the relevant parties in overcoming specific barriers in the context of each country, supporting innovative developments in technology-based teacher education.
Pre-service Teachers’ Perceptions and Practices of Learner Autonomy: A Case Study in Vietnam
Authors: Phan Thi Thanh Huyen , Nguyen Dao Thi Thuy , Ly Thi Thanh Truc , Duong Thi Diem Phuc , Mai Thi Van
Published: March 2024

This paper discusses learner autonomy (LA), which has recently been adopted as an important educational goal in the new competence-based curriculum for general education in Vietnam. Despite numerous studies on the initiatives to foster LA in various contexts, more research is needed to substantiate the literature on how pre-service teachers interpret and practice LA so that they could better reach the educational goal of fostering student autonomy in school settings. Drawing on data from surveys and interviews with pre-service teachers from Years 1 to 4 across seven disciplines of teacher education programs, the findings of our case study indicate that teacher education programs in Vietnam may prepare pre-service teachers to enact their autonomy in learning to some extent. Nevertheless, such programs need to provide to-be teachers with opportunities to actually control their learning in university settings so that they might better assist school students to develop their own independent learning and self-study. This paper thus concludes by raising two points concerning pedagogical obligation that pre-service teachers and teacher trainers should be aware of: first, that student autonomy relies substantially on teachers being supportive and flexible in devising learning activities; and second, that teacher education programs should equip pre-service teachers with sufficient knowledge, skills and resources to develop their own autonomy to enable their future students’ independence.

Authors: Aguye Akalewold Samuel , Berlie Abebe Damtew
Published: March 2024

Improving teacher quality, a pressing concern in modern education and improving instructional quality is becoming crucial particularly in the realm of foreign or second language learners. The purpose of this study was to investigate secondary school English as Foreign Language teachers’ general perceptions and practices of pedagogical content knowledge in the teaching of reading skills to grade nine students. The researchers used a descriptive survey design by generating quantitative data from English as Foreign Language teachers’ questionnaires and observation checklists as data collection tools. In total, 35 English as Foreign Language teachers participated in filling out the self-report questionnaire. To get insight into the implementation of pedagogical content knowledge, four English as Foreign Language teachers’ classroom practices were observed using a structured observation checklist and field notes during one academic semester in 2021. SPSS (IBM version 24) was used to analyse the data. Findings showed that English as Foreign Language teachers’ perceptions of pedagogical content knowledge seems to be slightly above average. The relationship between English as Foreign Language teachers’ general perception and pedagogical content knowledge implementation in the classroom had a moderately high positive relationship (r =0.67) between them. The results from the observation checklists revealed that teachers lack basic competence in pedagogical content knowledge implementation in teaching reading skills. To fill this gap, continuous professional development training schemes should be arranged for English as Foreign Language teachers.

Authors: Che Mat Che Mohamad Padali , Ku Johari Ku Suhaila , Mahmud Mohd Izwan
Published: March 2024

The purpose of this study is to test the validity of the healthy school organisation instrument (i-OS) and the holistic psychological well-being model of school organisations. A total of 500 teachers from 10 schools in the Klang Valley participated in the study. This instrument was created to assess four primary constructs: (i) the pressures placed on teachers' jobs in schools; (ii) the sources of teachers' employment in schools; (iii) the teachers' personal resources; and (iv) the teachers' overall psychological health in schools. The instrument's validity and reliability were examined using the Rasch model. The Rasch model was used because it is a more robust method than relying solely on Cronbach's alpha to gauge responder reliability. Furthermore, it was discovered that the school organisations' comprehensive psychological well-being model met the necessary fit index. The realm of study, theory, and practice will all benefit from this tool and model. The study's conclusions can also be applied to the creation of initiatives and programmes aimed at ensuring the wellbeing of educators and educational institutions.

Determinants as supporters or obstacles to optimizing the role of Bhabinkamtibmas in building public trust are analogous to two sides of one coin which revolves around the implementation of the main tasks, authority, and functions of the institution that accommodate it. These organizational factors have a sustainable impact on service effectiveness and strengthening relations between government institutions and the community. The article resulting from this research explains the determinants of optimizing the role of Bhabinkamtibmas in building public trust in certain loci. Data, information, and knowledge regarding the research focus were obtained through observations, interviews, and focus group discussions with informants as members of Bhabinkamtibmas (police, army, sub-district officials), community leaders, religious leaders, non-governmental organizations (NGOs), and academics. The data is analyzed using an interactive model which includes data collection, data condensation, and verification using the Important Performance Analysis (IPA) technique which is presented through a spider curve, and drawing conclusions. The research results found that there are several aspects as determinants that support or hinder efforts to build public trust in the demarcation of duties of the Makassar Indonesian Big City Resort Police (Polrestabes). Determinants as supporters or obstacles to optimizing the role of Bhabinkamtibmas in building public trust include the quality of public services, actor leadership style, transparency and accountability, public participation, effective communication, justice and equality in public policies and services, competency and integrity of the apparatus. The glue that unites the sustainability of these determinants is the leadership style and learning of the Bhabinkamtibmas organization as a representation of the Indonesian National Police (Polri).

A new method for obtaining a generalized solution of a mixed boundary value problem for a parabolic equation with boundary conditions of the third kind and a continuous initial condition is proposed. Generalized functions are understood in the sense of a sequential approach. The representative of the class of sequences, which is a generalized function, is obtained using the function interpolation operator, constructed using solutions of the Cauchy problem. The solution is obtained in the form of a series that converges uniformly inside the domain of the solution.

This study aimed to prepare edible films based on polysaccharides and whey proteins. Seven formulations were prepared from dextran, xanthan, and carrageenan with whey proteins, glycerol, and black seed oil. The mechanical and barrier properties were studied for edible films like thickness, tensile strength, elongation, and water vapor permeability. The use of equal concentrations of polysaccharides (2gr) with the presence of whey proteins (1gr) and glycerol as plasticizers gave the best elongation at the break of the film (178%) and water vapor permeability the highest value(5.7g.mm/m2.h.kPa). Film Thickness was 56µm and Tensile 28MPa.This edible film was the best among the other formulation used in molasses medium.

Together with a new series of imidazoles [2,1-b]benzthiazoles connected with various heterocyclic scaffolds, a novel Mannich base link with the drug Cefixime was also developed. In order to create the isoxazole ring, a Mannich base with a terminal methyl group was condensed with various substituted aromatic aldehydes, resulting in new chalcones. These chalcones were then brought closer together with hydroxylamine hydrochloride to produce new isoxazole derivatives. All compounds were identified by the spectra of carbon-13 (C13) nuclear magnetic resonance, proton nuclear magnetic resonance, and Fourier transform infrared spectroscopy. The effectiveness of certain novel compounds as anticorrosion agents was demonstrated by others.

The herbs have a huge role in development of pharmacology besides the role of veterinary medicine in development of human medicine The study aimed to evaluate the therapeutic efficacy of pomegranate peel and leaves of both thuja and tobacco in 5 cows, 15 sheep and 15 goats were brought to veterinary clinics on the outskirts of Baghdad suffering from health problems in the skin, upper respiratory tract and digestive system. Cases were treated topically or orally as a powder, aqueous solution, or ointment. The results showed that 66% of cases were cured. The cure rate was related to the severity of the infection or lesion, course of treatment, routes of administration and herbal formula. Also, the results did not show any side effects of the herbal during the treatment period. Pour- on using of tobacco leaf infusion for lice-infected goats gave a better result than in sheep. The thuja and peels of pomegranate have proven to healing as an ointment for wounds, sores and blisters. Also, the aqueous solution or powder of thuja and peel of pomegranate have proven effective in reducing symptoms in the digestive system and upper respiratory disorders. Both ointments of thuja and pomegranate gave acceptable results for the treatment of warts (papilloma). Therefore, the farmer can use these herbs in emergencies. Recommendation is conducting more clinical veterinary studies on pomegranate, thuja, and tobacco leaves and their medicinal propriety. Thus, the field of veterinary medicine is the best field for reviving biopharmaceutical research and comparative medicine.
