Authors: Savina L. K. , Khonchyk I. V. , Shulyk I. G. 
Published: January 2025

During operation, refractory concretes are exposed to the complex effects of thermal shock, corrosion, mechanical shock and abrasion, and the resistance of these materials depends on such factors as chemical composition, microstructure and phase transformations that occur at high temperatures. Given this, the present study investigated the effect of the amount of alumina cement of the Gorkal­40 brand and the addition of refractory clay on the main properties of fireclay concrete before and after heat treatment. It was found that the introduction of an additive of 0.5 % clay into the concrete mixture containing 15 % Gorkal­40 cement provides samples with a set of high property indicators: apparent density 2.19 g/cm3; open porosity 20.3 %; cold crushing strength after 7 days of curing — 40.8 N/mm2, after firing at a temperature of 1350 ºС — 35.8 N/mm2.
The pilot product in the form of burner stone from a concrete mix of optimal composition was made. After firing, the burner stone had no external defects (it was not melted, had no cracks or notches, and had a uniform yellow color). Properties of the satellite samples: cold crushing strength after 7 days of hardening — 41 N/mm2, after firing at a temperature of 1350 ºС — 38 N/mm2; open porosity and apparent density of the fired samples — 20.2 % and 2.18 g/cm3, respectively.
Based on the research results, the technology of the fireclay concrete mix of the SSHBG brand, which is produced by the Institute according to technical specification TU U 23.2—00190503—445:2019, was improved.

Microspheres of technogenic origin: the way to new technological solutions
Authors: Fedorenko O. Yu. , Monakhov S. V. 
Published: January 2025

The paper presents data on the ash microspheres compositions of domestic thermal power enterprises. The research results on the structural and phase features of the Kryvorizka TPP ash microspheres according to X­ray diffraction and electron microscopy data are provided. The physic­mechanical, thermophysical, and electrophysical properties of ash microspheres were determined. It is shown that zolospheres with a high iron oxide content (24—27 wt. %) are almost X­ray amorphous technogenic formations, but their heat treatment at temperature 850 °С allows to change of the phase composition in a directed manner. It was established that, as a result of such heat treatment, magimite, hematite, hercynite, as well as mullite and a small amount of magnesium spinel and quartz are formed in the zolospheres shells. The directed formation of various compounds in the phase composition of zolospheres allows to influence of such properties as thermal conductivity and TCLR, hardness, dielectric and magnetic characteristics, which determine the appropriate direction of their use.
The work also highlights our own positive experience of ash spheres used to obtain composite materials for various functional purposes. It is shown that the ash spheres of most domestic TPPs have a similar chemical composition, contain small closed pores inside the shells, and are characterized by low thermal conductivity and СTE. Therefore, it is better to use them as a filler for composite insulation, including heat­insulating paints for building structures and communications. Zolospheres that acquire a crystalline structure through heat treatment increase their abrasiveness due to the formation of phases with high hardness (hercynite, magnesium spinel). It is expedient to use such ash spheres as a secondary filler of diamond­abrasive composites for instrumental purposes. During grinding, they form additional cutting surfaces, which helps to increase the processing productivity of highly plastic alloys by 1.7—1.8 times while ensuring the necessary quality of diamond processing (Ra = 0.20—0.25 μm.) and reducing its cost by 1.5 times. On the other hand, ash spheres, in the shells of which ferromagnetic compounds (maghemite, hematite) are formed during heat treatment, have prospects for use as a filler for radio­absorbing composite materials and coatings.
The Flood and Kant’s Epistemology against Man’s Alienation in Wallace Stevens’ “The Comedian”
Authors: Benmezal Farid 
Published: January 2025

This article examines the connectedness between Wallace Stevens’ idea of a balance between reality and the imagination in his poem “The Comedian as the Letter C” and Kant’s idea that man’s knowledge of the world is always mediated by mental representations. Aware that the decline of spirituality means that man is left alienated in a thoroughly material world, Stevens strives to rescue humanity from spiritual emptiness and to make out of the same reality poetry in which the imagination brings meaning to man’s existence. In this poem, Stevens makes use of the motif of the flood as an intertextual response to Hegel’s reading of the Greek and biblical stories of the flood that places Kant in the biblical tradition in which man’s submission to God leads to his severance from his reality while the Greek story emphasizes the harmonious coexistence between man and nature. Owing to the nature of this study, this article relies on close reading, a technique advocated by the New Critics and Julia Kristiva’s intertextuality that insists on the presence of elements of one text within another. This methodology highlights that the flood in “Comedian” is a vehicle through which Stevens rejects Hegel’s anti-Kantianism and insists that Kant’s epistemology is the most suitable philosophical paradigm to create a union between man and nature in a secular age. This union is possible if the poet is able to reach a balance between reality and the imagination.
Normative Ethics and Descriptive Ethics Concerning the Context of Politeness in the ondhagga Tradition in Madura

Published: January 2025

Language and ethics are intrinsically linked, with ethics playing a crucial role in ensuring politeness and recognizing social distinctions among speakers. One regional language rich in ethical traditions is Madurese, particularly through a practice known as ondhagga. This tradition emphasizes the importance of speech and grammar tailored to the social position of the person being addressed. In Madurese culture, the speaker must consider the listener's social status to appropriately use ondhagga forms. This research highlights two types of ethics within this tradition: normative and descriptive ethics. Normative ethics focuses on defining the behaviors and values that are considered morally good within a social group, guiding individuals on appropriate actions without making judgments. On the other hand, descriptive ethics describes existing behaviors and their meanings, offering insight into actions without prescribing standards. The study analyzed twenty conversational samples across various contexts using qualitative, phenomenological methods. Data was collected through documentation, and analysis was conducted using data reduction and presentation techniques. To ensure validity, the research employed data triangulation and credibility testing. The aim was to explain how normative and descriptive ethics operate within the ondhagga tradition. The findings emphasize the importance of ethical communication, tailored to context and situation. It underscores that ethics in a language not only applies to Madurese but is relevant across all languages and cultures. Ultimately, language ethics reflects our nobility as human beings, as it shapes respectful communication in everyday interactions.

Published: January 2025

HCNG is hydrogen enrichment in Natural Gas and is stored in the pressurized form. The proportion of hydrogen typically varies from 5-30 of hydrogen in natural gas by volume percentage. Hydrogen is considered an imminent fuel due to the enormous potential of having a high energy yield (LHV – approx. 120 MJ/kg) and wide flammability range. HCNG can bridge the gap between Compressed Natural Gas (CNG) and hydrogen to enhance the usage of hydrogen by taking advantage of existing CNG infrastructure.
This particular paper is written to vitrine the typical emission calculation for the HCNG-fueled engines. Further to this study, the stoichiometric combustion equation for HCNG and ugas constant is also determined. To check whether the engine emissions comply with the standard emissions regulations, the emissions gas Analyser readings (in ppm) are essential to convert into mass-specific emissions (g/kWh). Here, for the conversion calculations, the ‘Ratio between densities of gas component and exhaust gas’ (ugas) plays a vital role. This is a unique value which changes according to the fuel composition. ISO 8178 part 4 has provided the ugas coefficient for various conventional fuels. However, for specific emissions calculations of HCNG blends, this coefficient is not readily available. In this paper, we have calculated the ugas coefficients for various HCNG blends for emissions determination and provided a sample calculation to showcase the same.

Published: January 2025

Pemilihan metode pengeboran yang tepat merupakan hal yang sangat penting terutama pada proyek proyek offshore (dikerjakan diatas sungai ataupun laut) yang umumnya mempunyai panjang bor yang dalam serta diameter yang besar. Salah satu metode pengeboran yang ada selain menggunakan “Kelly bar system” yang biasa digunakan pada pengeboran di darat, ada juga pengeboran dengan menggunakan metode sistim “sirkulasi”. Pada bagian “Approach Bridge” dan “Main Bridge” Jembatan Suramadu, pengeboran yang dipakai menggunakan metode “Sirkulasi”.Pembahasan pada tulisan ini di khususkan pada bagian “Approach Bridge” dikarenakan panjang bor yang dalam sekitar 80-90 meter serta dari data tanah yang ada kondisi lapisan tanah cukup bervariasi namun secara umum ditemukan lapisan tanah clay shale, dimana jenis tanah ini sangat sensitive terhadap ganguan pada proses pengeboran serta pengaruh cuaca, maka pada saat proses pengeboran memerlukan slurry stabilizer untuk mencegah kelongsoran dari dinding tiang bor. Slurry stabilizer yang dipakai adalah menggunakan mud dan bentonite. Setelah pembuatan tiang bor selesai maka tiang bor tersebut akan di uji untuk mengetahui daya dukung tiang, pengujian tiang tiang bor dilakukan dengan menggunakan metode Osterberg- Cell. Juga dilaksanakan Sonnic Logging test untuk mengetahui integritas tiang bor tersebut.

Lessons from the High-resolution Spectroscopy of AW UMa and ϵ CrA: Is the Lucy Model Valid?
Authors: Rucinski Slavek M. 
Published: January 2025

Abstract
A re-examination of high-resolution spectral monitoring of the W UMa–type binaries AW UMa and ϵ CrA casts doubt on the widely utilized L. B. Lucy model of contact binaries. The detection of the very faint profile of the secondary component in AW UMa leads to a new spectroscopic determination of the mass ratio, q
sp = 0.092 ± 0.007, which is close to the previous, medium-resolution spectroscopic result of T. Pribulla & S. M. Rucinski, q
sp = 0.101 ± 0.006, and remains substantially different from a cluster of generally accepted photometric results by several authors, concentrated around q
ph = 0.080 ± 0.005. A survey of binaries with the best-determined values of the mass ratio shows a common tendency for q
ph < q
sp. The tendency for systematically smaller values of q
ph may result from the overfilling of the primary lobe and underfilling of the secondary lobe relative to the Roche model geometry, as predicted by the K. Stȩpień model. Despite the observed moderate inter-systemic velocities, the photometric Lucy model may remain useful in providing approximate, though biased, results for the mass ratio. A complicating factor in detailed spectral analysis may be the occurrence of Enhanced Spectral-line Perturbations (ESPs) projected over the secondary profiles, appearing in different numbers in the two studied binaries. The ESPs are tentatively identified within the Stȩpień model as collision fronts or fountains of primary-component gas from the circumbinary, energy-carrying flow.
