Authors: Сунцов Андрей Евгениевич , Коршунов Сергей Александрович 
Published: February 2024

Рассматривается проблема идентификации сигналов утечек малой интенсивности (менее 5 м3/ч). Энергия таких сигналов в стационарном режиме работы магистрального трубопровода может быть в несколько раз меньше энергии шума. Соответственно, анализ сигналов утечек малой интенсивности требует применения специальных методов подавления шума и выделения полезного сигнала (повышения соотношения сигнал/шум). При исследованиях событий на защищаемом участке трубы решается задача выделения сигналов утечки, идущих изнутри участка. Для этой цели предложен метод фазовой декомпозиции, который позволяет отделить сигналы, идущие изнутри защищаемого участка трубы, заключенного между двумя парами гидрофонов, от сигналов приходящих извне этого интервала. Дальнейшему анализу подвергаются временные ряды, очищенные от шумов и сигналов, приходящих извне защищаемого участка. Таким образом, в результате использования метода фазовой декомпозиции соотношение сигнал/шум увеличивается. Приведен аналитический вывод метода, который выполняется в пространстве Фурье. Продемонстрированы результаты его применения к реальным данным гидрофонов на участке магистрального трубопровода. Показана эффективность метода: соотношение сигнал/шум увеличивается почти в 20 раз, что достаточно для явного выделения сигналов утечек интенсивностью 1 м3/ч и более в условиях стационарного режима.
The problem of identifying low-intensity leakage signals (less than 5 m3/h) is considered. The energy of such signals in the stationary mode of operation of the main pipeline can be several times less than the noise energy. Accordingly, the analysis of low-intensity leakage signals requires special methods of noise suppression and separation of the useful signal (increasing the signal-to-noise ratio). When investigating events on the protected section of the pipe, the problem of separating the leakage signals coming from inside the section is solved. For this purpose, the method of phase decomposition is proposed, which allows separating the signals coming from inside the protected section of the pipe from the signals coming from outside this interval. The time series, cleared of noise and signals coming from outside the protected area, is subjected to further analysis. Thus, the signal-to-noise ratio increases as a result of using the phase decomposition method. The analytical derivation of the method, which is performed in Fourier domain, is given. The results of its application to real data are demonstrated. The effectiveness of the method was shown: the signal-to-noise ratio increases almost 20-fold.

Проведена оценка соответствия разработки основным критериям наилучших доступных технологий.
Sorption purification is one of the safest and most available methods for emergency oil spill elimination. Currently, natural polymers and other hydrophobic materials with special properties are widely used as filter media, and vegetation waste-based sorbents are considered to be the most promising for this application. The purpose of this study is to investigate the process criteria for the use of leaf litter as oil sorbent in the water area oil spill containment and elimination. Leaf litter adsorption capacity was evaluated. Based on the sorption purification performance investigation results, leaf litter sizes recommended for the sorbent products manufacture were determined. It is shown that cylindrical booms filled with the leaf litter-based sorbent of 5–15 mm in size with packing density of 0.122 g/cm3are efficient for containment of oil slicks with film thickness from 1.5 to 2.5 mm and oil contact time of up to 90 minutes. The process flow schematic for oil sorbent and sorbent product manufacture is presented taking into account the secondary water contamination prevention. The developed process is assessed for compliance with the basic criteria of the best available technologies.
Макроміцети Національного природного парку «Гуцульщина» та їх антибактеріальні властивості

Published: February 2024

The ability of ethanol extracts of 20 species of macromycetes to inhibit the growth of bacterial cultures was studied. Their influence on indicators of superoxide dismutase and catalase activities in relation to three types of test cultures of microorganisms was established. Extracts of Cantharellus cibarius, Grifola frondosa Laetiporus sulphureus, Leccinum scabrum, Mycena leptocephala, Russula rosea, Strobilomyces strobilaceus showed the largest diameters of growth retardation of microorganisms of test cultures. The ability to counteract bacteria is a species-specific feature and does not depend on the trophic timing of macromycetes, the same applies to the ability to suppress the catalase activity of microorganisms. Extracts of macromycetes, which provoked inhibition of the growth of cultures, led to changes in the SOD activity of the studied bacteria: during incubation of M. luteus culture with mushroom extracts, which showed an inhibitory effect on the growth of microorganisms with a diameter of 8-12 mm, superoxide dismutase activity increased 2-3 times, during incubation of M. luteus bacteria with extracts that inhibited growth with a diameter greater than 12 mm, the enzymatic activity increased 8-10 times. The SOD activity of B. spizizeni increased by 40-80% at the 24th hour of the experiment with extracts, the use of which is accompanied by the formation of a 10 mm zone of growth inhibition, but already after 48 hours of the experiment, the indicators of the SOD activity of B. spizizeni decreased to the control values. SOD activity of E. coli increased on the 24th hour of the experiment by 1.4-1.6 times relative to the control values, even with the use of extracts that provoked inhibition of the growth of cultures with a diameter of 8 mm and remained high on the 48th hour of the experiment (in 1.2-1.3 times).
Review of New Directions in Second Language Pragmatics
Authors: Li Xi , Yang Liu , Huang Qiao 
Published: February 2024

The volume is edited in honor of Andrew D. Cohen, who is a preeminent and leading scholar in applied linguistics and has made great contributions to pragmatics in second language contexts. In particular, chapters in this volume address Cohen’s legacy in L2 pragmatics (second language pragmatics) in his seminal work (Cohen and Olshtain 1981), including learning, teaching, and assessing. More importantly, as the title of the volume indicates, new directions are presented, which is achieved not by simple application of Cohen’s idea, but by critical refinement. It is the latter that deserves scholars’ attention.

ABSTRACT
Strategies to advance action threshold development can benefit both civilian and military vector control operations. The Anastasia Mosquito Control District (AMCD) has curated an extensive record database of surveillance programs and operational control activities in St. Johns County, Florida, since 2004. A thorough exploratory data analysis was performed on historical mosquito surveillance and county-wide climate data to identify climate predictors that could be used in constructing proactive threshold models for initiating control of Aedes, Culex, and Anopheles vector mosquitoes. Species counts pulled from Centers for Disease Control and Prevention (CDC) light trap (2004–2019) and BG trap (2014–2019) collection records and climate parameters of temperature (minimum, maximum, average), rainfall, and relative humidity were used in two iterations of generalized linear models. Climate readings were incorporated into models 1) in the form of continuous measurements, or 2) for categorization into number of “hot,” “wet,” or “humid” days by exceedance of selected biological index threshold values. Models were validated with tests of residual error, comparison of model effects, and predictive capability on testing data from the two recent surveillance seasons 2020 and 2021. Two iterations of negative binomial regression models were constructed for 6 species groups: container Aedes (Ae. aegypti, Ae. albopictus), standing water Culex (Cx. nigripalpus, Cx. quinquefasciatus), floodwater Aedes (Ae. atlanticus, Ae. infirmatus), salt-marsh Aedes (Ae. taeniorhyncus, Ae. sollicitans), swamp water Anopheles (An. crucians), and a combined Total Mosquitoes group. Final significant climate predictors varied substantially between species groups. Validation of models with testing data displayed limited predictive abilities of both model iterations. The most significant climate predictors for floodwater Aedes, the dominant and operationally influential species group in the county, were either total precipitation or frequency of precipitation events (number of “wet” days) at two to four weeks before trap collection week. Challenges hindering the construction of threshold models were discussed. Insights gained from these models provide initial feedback for streamlining the AMCD mosquito control program and analytical recommendations for future modelling efforts of interested mosquito control programs, in addition to generalized guidance for deployed armed forces personnel with needs of mosquito control but lacking active surveillance programs.
“A Subject of Four Notes”
Authors: Renwick William 
Published: February 2024

This paper discusses the circumstances that drew
William Crotch into a highly specific and systematic
compositional procedure, and describes how the severe material
and procedural restrictions of his Introduction and Fugue on a
Subject of Four Notes, no others being used all thro' the
movement (ca. 1830) nevertheless permit the creation of a
successful musical work on both intellectual and artistic
scales. The analytical focus of the article is the manner in
which Crotch establishes and deploys a varied content through a
coherent and developmental design despite the self-imposed
limitations.
Modifying Interval-Class Vectors of Large Collections to Reflect Registral Proximity Among Pitches
Authors: Robison Brian 
Published: February 2024

The twelve-tone operations of transposition and
inversion reduce all 12-note collections to one set-class,
all 11-note collections to one set-class, and all ten-note
collections to one of six set-classes. Yet throughout this
century, composers have organized large collections in
different ways to produce distinctly characteristic
intervallic content. I propose here a modified version of
Allen Forte’s interval-class vector to preserve some
indication of registral proximity among pitches, assigning
fractional counts to intervals greater than six semitones
in order to derive interval-class vectors which distinguish
different sets of a given set-class.
Destructuring Cartesian Dualism in Musical Analysis
Authors: Covach John 
Published: February 2024

The following study represents work-in-progress. In
this preliminary study I will explore the topic of subject-object
dualism as it arises in musical analysis. My work is strongly
influenced by Martin Heidegger’s “fundamental ontology,” which he
presents in his important philosophical work, Being and Time
[1927]. I will argue that Heidegger’s critique of Rene Descartes’
systematic reduction of intellectual certainty to a fundamental “first
fact of knowledge”—the famous cogito, ergo sum—offers us a
useful guide in the consideration of dualism as it occurs in musical
analysis. Heidegger’s notion of destructuring (Destruktion) will
prove to be especially valuable in investigating this problem. The
exploration of subject-object dualism will then lead to consideration
of musical understanding and musical meaning, and concepts derived
from the writings of Heidegger and Hans-Georg Gadamer will be
employed as I suggest a number of preliminary solutions to problems
that will arise in the discussion of these issues.
Dissonance and Schumann’s Reckless Counterpoint
Authors: Alphonce Bo H. 
Published: February 2024

Work in progress about linearity in early romantic music. The essay discusses non-traditional dissonance
treatment in some contrapuntal passages from Schumann’s Kreisleriana, opus 16, and his Grande Sonate F minor,
opus 14, in particular some that involve a wedge-shaped linear motion or a rhythmic shift of one line relative to the harmonic progression.
From Similarity to Distance; From Simplicity to Complexity; From Pitches to Intervals; From Description to Causal Explanation
Authors: Rahn Jay 
Published: February 2024

Words and phrases specifying similarity and
distance abound in musical discourse. This essay explores
such pitch-predicates as “matches”, “is in the vicinity of”, and
“is closer to . . . than to”. Sought here are ways in which pitch
and pitch-interval predicates might be inter-connected logically.
Within a nominalist framework, an orderly progression from pitch-
to pitch-interval-predicates can be proven and interpreted
in terms of simplicity. Also indicated are connections
between the present formulation and issues of (i) dimension-
ality and explanation in psychoacoustics, Gestalt psychology,
and behaviorism, and (ii) nominalism and the “numerological
fallacy” in music theory.

Published: February 2024

Processes of categorization are known to be fundamental to
human cognitive processing. This essay reviews the characteristics of
two types of categories that give rise to conceptual representations.
One type, which has been demonstrated to have a graded structure, is

The Aims of Music Theory and Neurath’s Boat
Authors: Mailman Josh 
Published: February 2024

In this commentary, I will first clear the air of a
criticism Walker has made of Brown’s “Adrift on Neurath’s Boat.” Secondly, I will look at what issues arise when naturalizing music theory, by allowing revisions. Thirdly, I will critically address two proposals made by Brown regarding testing theories and the connection between aesthetic and nonaesthetic properties. Finally, I will
consider the ramifications of Brown and Dempster’s scientific model of
music theory and discuss alternatives to this model.
Review of Daniel Kazez, Rhythm Reading: Elementary Through Advanced Training (W.W. Norton and Company, 1997)
Authors: Marvin William M. 
Published: February 2024

The second edition of Rhythm Reading is a thorough
revision that improves upon its predecessor throughout. The book
contains a variety of exercises and musical examples, and the author
addresses several important notational topics that are neglected in
competitive texts. However, shortcomings in the pedagogy, and a
failure to address several issues of rhythmic performance found in the
standard music literature, limit the usefulness of this text beyond
the introductory stages.

TEMPERATURE DEPENDENCE OF THE FRONT LATHE TOOL SURFACE ON EVOLUTIONARY CHANGES IN TRIBO-DEFORMATION INDICATORS OF PROCESSING
Authors: Fominov Evgeny , Gvindzhiliya Valeriya , Fisunova Elena , Marchenko Andrey , Suhomlinova Viktoriya 
Published: February 2024

The study objective is modeling the temperature distribution on the surface of a heavily loaded tribocontact - front surface of a lathe tool - chips taking into account evolutionary changes in the cutting system.
The task to which the paper is devoted is to assess the influence of evolutionary changes of tribodeformation parameters of the cutting process on the average and maximum temperature of the front surface of the lathe tool.
Research methods. Contact temperatures are found out on the basis of mathematical modeling using data obtained during field experiments at longitudinal turning of 15X2NMFA steel blanks without cooling by T15K6 hard alloy plates. During resistance tests, the chip contact length with the front surface and the chip reduction coefficient used for calculation are determined, as well as the average temperature in the cutting zone, the value of which is used to assess the adequacy of the results obtained by digital modeling.
The novelty of the work. Forecasting the temperature increase on the front surface of the cutter, taking into account the contribution of evolutionary changes in tribodeformation parameters of cutting.
The results of the study. In the studied cutting system, according to the results of resistance tests, a decrease in the chip reduction coefficient is recorded over the processing time. The temperature distribution on the front surface of the cutter is modeled in two versions: taking into account the evolutionary adjustment of the chip reduction coefficient and related parameters – sliding velocity and thickness of the plastically deformed layer in the chip, and without taking into account their changes. It is found out that modeling adjusted for changes in tribological indicators allows to obtain calculated values of the temperature of the front surface closest to the experimentally recorded of average temperature in the cutting zone.
Conclusions: Forecasting contact temperatures adjusted for evolutionary changes in tribodeformation parameters will allow to determine more accurately the moment in the evolution of the cutting system at which critical temperature values can be reached, and further processing is associated with the risk of critical wear or deterioration of the treated surface.

Published: February 2024

Healthy youth eating habits are crucial for optimal growth and development. It helps build a strong immune system and reduces the risk of chronic diseases. In Islam, there is a focus on maintaining a healthy lifestyle, including a healthy diet, guided by the Qur’an and the teachings of Prophet Muhammad (ﷺ). The article uses a narrative review to highlight the potential applicability of the halalan toyyiban concept (as a faith-based intervention) to promote a healthy diet among youth. Faith-based intervention involves integrating religious beliefs into the intervention process. To provide context, this article explores the application of interventions such as multimodal nutrition education and digital approaches to improve dietary habits among youth. Various interventions targeting university students' dietary habits yielded mixed results. This highlights the necessity for multifaceted intervention approaches. The article posits combining the halalan toyyiban concept with digital technology to enhance university students' healthy dietary practices.
Ideal-Real-Actual
Authors: Jessen Jonas Falzarano , Mannov Adrienne , Andersen Astrid Oberborbeck 
Published: February 2024

Abstract
Based on our experiences from ongoing collaborations with computational engineers over the course of six years and two interdisciplinary research projects, with this article we suggest that the building of collaborations between anthropology and computational sciences that alter disciplinary boundaries and bridge epistemic differences can be accomplished through three levels of engagement: a shared research project, becoming involved in each other's theoretical universes, and crafting physical spaces for shared intellectual practice. Taking an empirical point of departure in our colleagues’ attempt to cross the methodological and epistemic divide between engineering and anthropology through game theory, we introduce how the distinction between the ideal, the real and the actual serves not only as a model of our collaborations but also as a generalisable model for future collaborations across anthropology and computational sciences.
