Individual projects. Haven't we missed the birth of a new genre?
Authors: Амрахова А.А. 
Published: August 2024

Традиционно сущностные признаки индивидуальных проектов (ИП) определяются апофатическим путем. Автор данной статьи отрицание какой-либо их связи с известными жанрами и формами осмысляет в качестве родового свойства. Показывается, как особенности ИП формируются на пересечении двух плоскостей — жанровости и программности. Возможность трактовки ИП как жанра доказывается некоторыми положениями теории референции, прототипической семантики и когнитивной лингвистики. Выводы, к которым приходит автор: стабильными признаками в ИП следует считать отсутствие тематизма, отсутствие ориентации на классические жанры и типовую музыкальную форму. Референциальная отсылка производится не к миру, а к когнитивным моделям. Этих стабильных признаков достаточно, чтобы отнести ИП к новому классу жанров.
Traditionally, the essential features of individual projects are defined in an apophatic way. The author of this article conceptualizes the denial of any connection with known genres and forms as a generic property. It is shown how the features of individual projects are formed at the intersection of two planes—genre and programmatic. The possibility of treating individual projects as genres is proved by some provisions of the theory of reference, prototypical semantics, and cognitive linguistics. The author comes to the following conclusions: in individual projects, the following stable features should be considered absence of thematicism, absence of orientation to classical genres and typical musical form, referential reference not to the world, but to cognitive models. These stable features are enough to refer individual projects to a new class of genres.
Problems of genre classification of Gregorian chant
Authors: Москва Ю.В. 
Published: August 2024

Григорианское пение, будучи началом всей западной профессиональной музыки, вплоть до сегодняшнего дня не прерывает своих генетических связей, выраженных в преемственности интонационности, ладовых систем, музыкальной нотации, формообразовании. Так как григорианское пение неразрывно связано с богослужением, его жанровые характеристики детерминированы прежде всего смыслом и общей структурой литургии. Из-за трудности совмещения разных критериев систематизация григорианских жанров довольно сложна и не единообразна. Кроме того, отдельные жанры могут занимать промежуточное положение. В силу того, что литургика складывалась постепенно, должна быть принята во внимание и огромная временнáя дистанция между возникновением отдельных музыкально-богослужебных жанров, а также стилистическая неоднородность жанров в течение их многовекового функционирования. В статье представлены основные классификации, используемые в современных научных трудах, учебниках по григорианскому пению и предложена собственная версия.
Gregorian chant, as the beginning of all Western professional music, has not interrupted its genetic ties, expressed in the continuity of intonation, harmony systems, musical notation, formal design. Since Gregorian chant is inseparably linked to the liturgy, its genre characteristics are primarily determined by the meaning and general structure of the liturgy. Because of the difficulty of combining different criteria, the systematisation of Gregorian genres is rather complex and not uniform. In addition, individual genres may occupy an intermediate position. Due to the fact that liturgics developed gradually, the enormous time distance between the emergence of individual musical and liturgical genres, as well as the stylistic heterogeneity of genres during their centuries-long functioning, must also be taken into account. The article presents the main classifications used in modern scholarly works, textbooks on Gregorian chant and proposes author’s own version.

AbstractThe car assembly industry continues to grow, especially in Indonesia. Logistics is one of the fields that supports the car assembly industry such as the Cross-dock warehouse. The Cross-dock warehouse itself has a capacity limit in receiving queues of containers received in the truck unloading waiting area. Queue analysis was carried out at the Cross-dock company in the car assembly industry in Cikarang using the Queue method (M/M/S). Where the current container receiving capacity is obtained at a maximum of 12 containers per hour and the unloading capacity of 2 containers per hour will not exceed the waiting capacity for container unloading as many as 8 containers, if it is found that the arrival of containers exceeds 12 containers, it will result in the container being outside the Cross-dock system and must be outside the Cross-dock warehouse. AbstrakIndustri perakitan mobil terus berkembang khususnnya di Indonesia. Logistik adalah salah satu bidang yang mensupport industri perakitan mobil seperti adanya gudang Cross-dock. Gudang Cross-dock sendiri mempunyai batasan kapasitas dalam menerima antrian container yang diterima di area tunggu bongkarang truk. Analisa antrian dilakukan pada perusahaan Cross-dock di Industri perakitan mobil di Cikarang dengan menggunakan metode Antrian (M/M/S). Dimana didapatkan kapasitas penerimaan container saat ini sudah maksimal dengan 12 container perjam dan kapasitas bongkaran 2 kontainer perjam tidak akan melebihi dari kapasitas tunggu bongkaran kontainer sebanyak 8 kontainer jika didapati kedatangan kontainer melebihi dari 12 kontainer maka akan mengakibatkan container berada diluar dari system Cross-dock dan harus berada di luar dari gudang Cross-dock.

The article presents the results of the most complete molecular epidemiology study of one of the most epidemically significant enteroviruses (EV), both globally and in Belarus – Echovirus 30, including a description of its evolutionary trajectory and routes of geographic distribution.The purpose of the presented work was to study a molecular epidemiology of Echovirus 30 in the Republic of Belarus from 1997 to 2021.During the observation period, Echovirus 30 was the second most common type of EV after Coxsackievirus B5. The highest Echovirus 30 activity was registered at the time of enteroviral morbidity epidemic upsurge. Intestinal and neurological forms predominated in the spectrum of Echovirus 30 clinical presentation. We identified 10 different genetic variants of Echovirus 30 that circulated in Belarus, which were included in three global Echovirus 30 genotypes ‒ ECHO30_E, ECHO30_F and ECHO30_H. At the time of morbidity epidemic rises in 1997, 2013‒2014, and 2017‒2018 there was a parallel circulation of two different genetic variants of the virus belonging to the same (2013‒2014) or different (1997, 2017‒2018) genotypes. Simultaneously circulating genetic variants of Echovirus 30 had different evolutionary trajectory and/or routes of geographic distribution.The obtained results are important for understanding the epidemiological processes underlying the enteroviral morbidity in the Republic of Belarus.

The article describes the results of experimental studies on diffusion welding under conditions of hot isostatic pressing with preliminary heat treatment of the surface of workpieces made of a number of steels and alloys by nanosecond pulses of laser ultraviolet radiation. Estimates of the characteristics of laser radiation and the parameters of the modified surface layer due to its melting by a laser pulse are given. It is shown, that the processing of samples from a heat-resistant nickel-based alloy CrNi55MoWZr by a scanning beam of nanosecond laser pulses with a wavelength of 355 nm, a duration of 10 ns and an energy density of 2 J/cm2, following at a frequency of 100 Hz, improved the mechanical properties of the weld. The ultimate strength increased by 10 %, and the elongation increased by 20 %. In addition, the use of a laser made it possible to reduce the temperature of the diffusion welding process by 160 °C while maintaining the mechanical properties of the welded joint. The most probable reason for the improvement of the properties of the welded joint was the appearance of low-temperature super-plasticity caused by the formation of a fine-grained surface structure because of preliminary laser processing of workpieces.

A study of the parameters of the high-temperature background of internal friction of a dispersed-hardened polycrystalline CrNi29Co28WMoTi alloy has been carried out. It is established that the transition of the investigated alloy from an elastic to a viscoelastic state occurs when the temperature limit Tcr = 791 K is reached in at least two stages. The first stage determines the migration of point defects of the crystal structure along the grain boundaries at low deformation in the low-temperature region, which corresponds to the diffusion activation energy of 0,51 eV. The second stage determines the separation and movement of dislocations from the impurity atoms, as well as the appearance of grain boundary sliding in the high-temperature region. This requires an activation energy of 0,86 eV. The relative decrease in the shear modulus in the temperature range 300 – 890 K was ≈ 0,15. To determine the temperature boundary of the Tcr, a formula is proposed that allows calculating the temperature of the Tcr based on data on the activation parameters of the high-temperature background of internal friction. In addition, a general thermodynamic condition for the transition of a material from an elastic to a viscoelastic state corresponding to high-temperature deformation mechanisms is formulated. It is shown that the temperature boundary that determines the beginning of the transition of a material from an elastic to a viscoelastic state can be used to diagnose the heat-resistant properties of nitrided alloys as an additional criterion.

Published: August 2024

Cu(x)/NiFe2O4(y) magnetic composites with different component ratios were prepared by chemical reduction of copper cations in the presence of sonicated nickel ferrite. Separately synthesized Cu and NiFe2O4 nanoparticles, as well as composites of copper particles supported on nickel ferrite, were characterized by X-ray diffraction spectroscopy and scanning electron microscopy. Based on the determination of the specific surface area, the NiFe2O4 sample heat-treated at 500 °C was selected as the support for the catalytically active Cu particles. The electrocatalytic activity of Cu(x)/NiFe2O4(y) composites deposited on a cathode was investigated in the electrohydrogenation of acetophenone (APh). It was shown that the electrocatalytic activity of these composites appears starting from the percentage ratio of their components x:y = 40:60. This was expressed as an increase in the rate of electrocatalytic hydrogenation of APh and its conversion compared to the electrochemical reduction of APh under similar conditions. It was suggested that the slightly lower rate of APh hydrogenation on Cu/NiFe2O4 composites compared to Cu particles is due to the poor electrical conductivity of the nickel ferrite support.
Studi Pengaruh Kontaminasi Properti Rheology Water Based Mud di Lapangan Sunyu

This project focuses on Investigation of effect of contaminants on the Rheological Properties of Water-based Drilling Mud. For any drilling operation to be termed successful, care must be taken during the selection and application of the drilling fluid which are key factors that should be considered. Any actions contrary to carefully selection and application of drilling fluids could have very dire consequences. Based on the experiment work done on water base mud system to ascertain the effect of contaminants (salt, silica sand, cement and carbonate) on the rheological properties and performance of the mud, it shows that the presence of a contaminant on the drilling mud either reduces or increases the rheological properties of the mud system and in turn affects the rate of penetration, it performance and also poses serious drilling problems. It was observed that the presence of Sodium salt in the mud system increased the fluid loss into the formation. It was further observed that while Apparent Viscosity, Gel Strength increases as the mass increase from 1g to 5g, the pH and Plastic Viscosity almost did not change. The Yield point increases little. With Cement as contaminant, it shows all rheological properties of the mud increased markedly, as the quantity of the cement used is increased from 1g to 5g and the pH does not change. Silica contamination has not showed any marked effect on the nature of the drilling mud. In fact, the more the amount of the contaminant (Silica) is added, the closer it properties are to the blank sample that do not have contaminants. The carbonate effect is largely on the Gel strength which decreases as the amount of added carbonate increases. The pH has no charges, which also means carbonate keeps the mud in it alkaline state, as it was the case with cement.
