The study of ferrites is currently one of the most important directions in scientific field, which is confirmed by a large number of publications on this topic. Ferrites are promising mate-rials to be used in high-frequency electronics. The ferrite with the structure of magnetoplumbite is the most promising for the needs of microwave electronics, namely, barium hexaferrite BaFe12O19, as well as solid solutions based on it. The substitution of iron atoms in the structure of barium hexaferrite by other elements such as aluminum or titanium leads to significant changes in physical properties such as magnetic permeability, saturation magnetization, coercive force, Curie temperature, ferromagnetic resonance frequency, electrical conductivity. Thus, understanding how each of the iron-substituting elements affects the physical properties of a solid solution based on barium hexaferrite gives us the opportunity to smoothly adjust the characteristics of ferrite for a specific engineering task. The present paper studies the effect of the substitution of iron in the structure of barium hexaferrite by the aluminum and titanium atoms upon the change in parameters of the crystal lattice and physical properties. Monophase samples based on barium hexa¬ferrite of the BaFe12O19, BaFe11AlO19, BaFe11TiO19, and BaFe11Al0.5Ti0.5O19 compositions were obtained by the solid-phase synthesis. The degree of substitution of iron by aluminum or titanium, as well as joint substitution by aluminum and titanium was the same for all samples. The resulting samples were studied by X-ray diffractometry, electron microscopy, and differential scanning calorimetry. According to the X-ray diffraction analysis data, the patterns of changes in parameters of the crystal lattice were revealed following the atom substitution. The Curie temperature for all the studied samples was measured by the method of differential scanning calorimetry. Conclusions are drawn about the influence of the substituting element on the Curie temperature value.

Published: November 2023

Realising the full potential for educational technologies to improve the student experience is a challenge for higher education institutions. Although academic resistance is often blamed for poor dissemination of teaching technologies, recent literature has more satisfactorily framed the issue in terms of intransigent organisational culture. Features of higher education organisational culture that are conducive to innovation include senior executive support, freedom to experiment and permission to fail and interdisciplinary and cross-institutional engagement. One approach to changing organisational culture is to establish new organisational structures embodying positive traits. This study qualitatively evaluated a technology in teaching innovators group established in 2018 in a science, health and engineering faculty of an Australian university; it provides evidence that the group improved the culture of teaching technology innovation by creating a safe space for innovation, which members then disseminated into their departmental communities. The study also found that the group created a forum for teaching technology innovators to engage with stakeholders in the university’s learning and teaching and information and communication technology units, leading to improved outcomes for the university’s learning environment.
Implications for practice or policy

Teaching technology dissemination in higher education can be enhanced through a community of practice model.
Higher education learning technology environments can be improved through an innovators group leading to greater cross-institutional collaboration.
Educational technology staff may be able to overcome academic resistance to strategic projects by pursuing a community of practice approach.
A truncation error bound for branched continued fractions of the special form on subsets of angular domains
Authors: Bodnar D.I. , Bodnar O.S. , Bilanyk I.B.
Published: November 2023

Truncation error bounds for branched continued fractions of the special form are established. These fractions can be obtained by fixing the values of variables in branched continued fractions with independent variables, which is an effective tool for approximating complex functions of two variables. The main result is a two-dimensional analog of the theorem considered in [SCIAM J. Numer. Anal. 1983, 20 (3), 1187$-$1197] for van Vleck's continued fractions. For its proving, the $\mathcal{C}$-figure convergence and estimates of the difference between approximants of fractions in an angular domain are significantly used. In comparison with the previously established results, the elements of a branched continued fraction of the special form can tend to zero at a certain rate. An example of the effectiveness of using a two-dimensional analog of van Vleck's theorem is considered.

Authors: Lunag Agustin B.
Published: November 2023

Traditional rice varieties (TRVs) are valued genetic resources because they contain important economic value traits needed to integrate and broaden rice's genetic pool and variability.  In this study, twenty-seven TRVs including a check variety (Mindanao – RS25) collected from different locations in Nueva Vizcaya, were subjected to DNA analysis to explore the genetic diversity of the collection and to determine possible aromatic TRVs in the presence of the fgr-gene.  TRVs demonstrate high genetic diversity based on the relatively low similarity coefficient of 0.12 using 15 robust short tandem repeat (STR) markers. The molecular diversity analysis divided TRVs into two major clusters/groups with eight sub-clusters. Cluster I comprised 15 TRVs along with the check variety, mostly grown in high altitudes/elevation (>500masl) or cooler climatic conditions, the japonica types. Furthermore, in Cluster II, 12 TRVs were commonly cultivated at lower elevations (100-500 masl) or warmer climatic conditions (indica sub-species).  Moreover, the presence of the fgr-gene allele was observed in TRVs assessed at both production sites. Finally, the province of Nueva Vizcaya had a preliminary characterization and initial conservation of its TRVs, in which these diverse germplasms could offer a valuable gene pool and rare traits for future varietal improvement programs in rice.

The use of steroids among bodybuilders is considered typical by many, probably due to the tendency to become exceptionally lean and masculine. However, as anabolic steroids may cause adverse effects, this may make steroid-using bodybuilders vulnerable to unhealthy eating and perception of body image. Therefore, a study was conducted to determine whether steroid-using bodybuilders have different nutrition knowledge and attitude, body image perception and cognitive ability compared to their non-steroid-using counterparts. Fourteen amateur bodybuilders, including seven self-claimed steroid users, voluntarily agreed to participate in this study. Nutrition knowledge and attitude were determined using established self-administered questionnaires. While body image perception and cognitive ability were assessed using the Adonis Complex questionnaire and mental rotation test, respectively. When comparing steroid and non-steroid users, there was no difference in nutrition knowledge and attitude.

Konflik Afghanistan yang telah berlangsung lama belum menemukan titik temu perdamaian antara pemerintah Afghanistan dan Taliban sehingga melibatkan semua pihak terkait, termasuk negara-negara besar seperti Amerika Serikat (AS). Pemilihan Indonesia sebagai mediator konflik merupkan hal yang menarik mengingat posisi Indonesia yang notabene berada di kawasan asia Pasifik yang jauh dari pusat konflik. Untuk menganalisis arah politik luar negeri afghanistan dan faktor-faktor terhadap Indonesia, penulis menggunakan metode kualitatif-eksplanatif, penggalian data melalui wawancara, penelusuran buku, jurnal dan berita online, serta menggunakan konsep analisis politik luar negeri K. J. Holsti. Penelitian ini menemukan bahwa pengambilan keputusan Afghanistan terkait resolusi konflik dipengaruhi oleh faktor-faktor internal dan eksternal. Ketertarikan Afghanistan terhadap Indonesia didorong oleh beberapa kesamaan, antara lain, karakteristk penduduk Muslim, negara demokratis, serta peran ulama. Selain itu, keaktifan Indonesia dalam menjaga perdamaian dunia, pengalamannya dalam menangani konflik dalam negeri yang majemuk, politik luar negeri yang netral dan tidak memiliki kepentingan apapun di konflik afghanistan, sekaligus pengaruh ormas Islam dalam perdamaian dan pembangunan Indonesia dan dunia telah menarik perhatian Afghanistan untuk memilih Indonesia sebagai mediator.
