On the well-posedness of nonlocal boundary value problems for a class of systems of linear generalized differential equations with singularities
Authors: Akhalaia Shota , Ashordia Malkhaz , Talakhadze Mzia
Published: October 2022

The well-posed problem for a nonlocal boundary value problem is considered for a singular system of linear generalized ordinary differential equations. The considered system is analogous to the system corresponding to the n-order ordinary differential equation. Along with the standard well-posed question, there is considered the so-called conditionally well-posed one. The effective sufficient conditions are established for both problems.

We prove via a Galerkin approximation the time local existence of regular solutions to a Landau–Lifshitz–Bloch equation with applied current in a bounded domain. The uniqueness of the solution is also established.
Moreover, we show the global in time existence of a regular solution in dimension two.
On deferred statistical convergence of complex uncertain sequences
Authors: Debnath Shyamal , Das Bijoy
Published: October 2022

Complex uncertain variables are measurable functions from an uncertain space to the set of complex numbers and are used to model complex uncertain quantities. In this paper, we introduce the deferred-statistically convergence concepts of complex uncertain sequences, deferred-statistically convergence almost surely, deferred-statistically convergence in measure, deferred-statistically convergence in mean and some relationship among them are discussed.
Three-dimensional finite element analysis and research of leakage magnetic field of flake, pit, through-hole defect in petroleum pipelines
Authors: Zhou Feng , Chen Yu , Zhao Han , Hu Heng
Published: October 2022

Flake, pit and through-hole defects are the three common types of defects in oil pipelines. In practical testing applications, it is necessary to clarify the magnetic leakage characteristics of different defects and set reasonable detection points to distinguish different types of defects accurately and quantify the degree of each defect precisely. In this paper, the leakage magnetic field of flaky, pitted and through-hole tube wall defect is analyzed. Using three-dimensional finite element simulation, the spatial stereo model of leakage magnetic field is inverted by extracting the data of characteristic nodes. The distribution of the leakage magnetic field in space, for the radial and circumferential components is obtained. On this basis, the effect on the main components of magnetic leakage field at different locations in space is determined, and the best of placing a potential sensor for detecting three kinds of defects in space are derived. This provides a basis for determining sensor locations in magnetic leakage detection devices, inverting defect models from multi-sensor data and accurately quantifying the degree of defects.

Published: October 2022

Die hohe Leistungsdichte eines elektrischen Antriebs wird in der Regel über eine hohe maximale Rotordrehzahl erreicht. Dies erfordert nicht lösbare Fügeverbindungen sowie thermisch unterstützte Montageprozesse. Der Einsatz einer Rotorwelle, Wuchtscheibe und Magnetfixierung mit federndem Verhalten ermöglicht den Entfall thermischer Prozesse sowie die Demontage treibhausgasintensiver Magnete. Potenziale sowie Herausforderungen dieser neuen Rotorkomponenten werden in diesem Beitrag vorgestellt.

In industriellen Montage- und Logistikprozessen führen repetitives Tragen schwerer Lasten, Überkopfarbeiten oder Zwangshaltungen zu starken körperlichen Belastungen, die hohe Personalausfallquoten und geringe Arbeitsattraktivität zur Folge haben. Dieser Beitrag orientiert sich am Operator-5.0-Gedanken und stellt ein neuartiges Konzept für den kombinierten Einsatz von sensorischen Exoskeletten und fahrerlosen Transportfahrzeugen mit dem Ziel verbesserter Arbeitsergonomie und -produktivität vor. Aufbauend auf den funktionalen und prozessualen Anforderungen werden eine Systemarchitektur und Steuerungssoftware sowie intelligente Methoden zur Mensch-Technik-Interaktion vorgestellt. Dabei werden zum einen eine automatisierte, prozess- und mitarbeiterspezifische Materialbereitstellung und zum anderen eine informatorische und physische Verbesserung der Arbeitsergonomie verfolgt. Das entwickelte Konzept wird im Beitrag durch exemplarische Anwendung auf Lager- und Montageprozesse im Automobilumschlag validiert.

Welche Gestaltungsdimensionen für eine lernförderliche Entwicklung eines digitalen Assistenzsystems zum Tragen kommen sollten, ist Thema des folgenden Beitrags.
Entwicklung eines Condition-Monitoring-Systems für Niederspannungsmotoren
Authors: Reuter Thomas , Schmidt Jens , Grundmann Andreas
Published: October 2022

Der Verbrauch von elektrischen Antrieben in der Industrie und dem verarbeitenden Gewerbe beträgt in Deutschland fast zwei Fünftel des gesamten Stromes. Somit werden den Elektromotoren eine Schlüsselrolle bei der Energieeinsparung zugeschrieben. Besonders hoch liegt die Energieeinsparung im Leistungsbereich zwischen 0,75 kW und 40 kW, da hier die meisten Betriebsstunden im Jahr anfallen. Gleichzeitig spielt neben der Energieeinsparung auch die Instandhaltung von elektrischen Antrieben eine entscheidende Rolle, da bei plötzlichen Ausfällen hohe Kosten durch Produktionsausfälle oder Reparaturen entstehen können. Um beiden Kriterien gerecht zu werden, wurde ein universell einsetzbares Condition-Monitoring-System entwickelt. Unter Anwendung der integrierten Schwingungsmessung konnten aus unterschiedlichen Belastungs- und Schadensfällen und den daraus ermittelten Kennwerten Vorhersagemodelle und Trendanalysen abgeleitet werden.
Sensationalizing Industrial Food in Documentary Film
Authors: Khan Sabiha Ahmad
Published: October 2022

As a subset of food media meant to tantalize palates, food documentaries typically sensationalize the impoverished state of the entire food supply. This essay focuses on the food documentaries Hybrid (2000), King Corn (2007), Sunú (2015), and OMG OMG (2013), which variously treat “industrial food” as not an object of scorn but a useful category of resistance and engagement. When read through queer ecocritical and feminist materialist lenses, such films create an opening for ways of accounting for and living with the monstrosities of nature that typically arrest the gaze of sensationalism. These food films consider the family and the household not merely as units of passive consumption but as sites of considered provisioning that struggle to account for issues of food justice, food sovereignty, and ecological awareness in a world of ongoing environmental degradation.
A Warm Meal and Kisses Too
Authors: Murray Sarah
Published: October 2022

Awareness of computers and computation rose considerably in the United States between 1939 and 1969. Press attention and public demonstrations showcased early robots and the push-button kitchen as two approachable yet fantastical examples of how computing processes might be applied to social life. Media coverage was hyperbolic and sensational, but also cautiously enthusiastic, skeptical, and sometimes dismissive. Public displays and print media consistently engaged signifiers of white, middle-class womanhood during the multidecade era when computers went from calculating machines to technologies families could begin to imagine in their homes. While much scholarship theorizes sensationalism as affective excess in opposition to the rational, the emergence of computing in this period necessitates a new consideration of sensationalistic media practices. The case of how publics were introduced to early ideas about computers is an opportunity to consider the complexity of sensationalism as a bundle of affects anchored in the iconography of white femininity, a mode I term sensible sensationalism.

Graphitic-carbon nitride (g-C3N4) (GCN) has emerged as the most promising material for the fabrication of next generation cutting–edge electronic and optoelectronic devices, due to its excellent and promising electrical and physicochemical properties. In this work we report on strategies to enhance the electrical conductivity of GCN thin films through the formation of heterostructures using silver nanoparticles (Ag). The synergistic effect of silver nanoparticles doping on structural and transport properties of GCN thin films was studied in detail. The structural and morphological changes in GCN polymer owing to the inclusion of silver nanoparticles were examined through Scanning electron microscopy, Fourier transform spectroscopy and X-ray diffractometer techniques. The conformational modifications in GCN polymer chains due to silver nanoparticles doping greatly enhanced the electrical conductivity of GCN thin films. The inclusion of silver nanoparticles in GCN polymer matrix decreases the barrier energy and enables the charge carrier hopping easily leading to improved electrical conductivity. The electrical conductivity of GCN-Ag composite thin film was enhanced by two folds due to the silver nanoparticles inclusion in comparison to conductivity of the pristine GCN thin film. The presence of Ag nanoparticles in the composite film plays a substantial role in improving the dielectric attributes of the pure GCN. Therefore, the doping by using silver nanoparticles might be a suitable strategy for effectively tailoring the electrical conductivity and dielectric properties of GCN thin films and can be used as flexible conducting electrode material towards fabrication of electronic and optoelectronic devices

We systematically studied the structure, electronic, elastic and optical properties of BiGaO3 type perovskite cubes. We also report the calculation of all properties listed in the title of GGA-PBE approximation to BiGaO3.This material has a band gap which can be considered as an indirect band gap. The maximum valence band is represented by the M point (VBM), whereas the conduction band is represented by the X point (CBM)The electronic structure of BiGaO3 shows that it has a semiconductor indirect band gap of 1.37 eV.The elastic constant was determined in equilibrium confirming its accuracy. The bulk, shear, and Young's modulus were all extracted from the data. Poisson's ratio was also found. The confirmed structural parameters were in good agreement with the previously calculated experimental data. Our research suggests that BiGaO3 is a promising piezoelectric, multiferroic, ferroelectric, and photo catalytic material.
Active Front Wheel Steering System using Yaw Rate Estimation based Fuzzy Logic Due to Various Lateral Wind Disturbance
Authors: Aparow Vimal Rau , Lun Lok Tze
Published: October 2022

The paper devised and compared the performances of PID, fuzzy-tuned PID and fuzzy logic controller in an Active Front Wheel Steering system to stabilize a 9-DOF nonlinear passenger vehicle when subjected to lateral wind disturbance. The vehicle model was derived mathematically and verified with data from IPG CarMaker at a longitudinal speed of 80 km/h. Initially, the disturbance test was conducted using three lateral wind disturbance profiles to test for controller resiliency with zero steering input. Then, a simple but effective yaw rate observer was derived without compromising the linearity of the vehicle model to simulate the disturbance test with a double lane change (DLC) steering input. A more extreme disturbance magnitude was evaluated in the latter test using the developed control designs. The three controllers showed good performances in both disturbance tests, with fuzzy logic having the lowest error out of the three, which is less than 5% for using the estimated yaw rate observer.

Bien común y sostenibilidad de base comunitaria para México. Aportaciones de la universidad pública y la Iglesia católica
Authors: Jiménez Martínez Nancy Merary , García-Barrios Raúl
Published: October 2022

A partir de una reflexión crítica de la sostenibilidad, en que identificamos que su dicurso ha estado regido por los supuestos del bien común del neoliberalismo progresivo, proponemos alternativas de interpretación ética y epistemológica de este concepto; es decir, lo trasladamos hacia un campo de reflexión y acción regido por una noción alternativa de bien común. Para ello, hacemos uso de tres elementos: ampliar la experiencia cooperativa humana, descrita por Graeber (2011), la tradición del pensamiento neotomista de MacIntyre y el sujeto social marxista de Lukács. El resultado es otro concepto de bien común, rico en elementos y determinaciones, para idear un esquema productivo y social más justo y solidario, con instituciones apropiadas para desarrollar y alcanzar la sustentabilidad. ¿En qué comunidades humanas puede ser esto posible? En comunidades maduras, cuerpos sociales capaces de vislumbrar bienes superiores, subsumir y supeditar coherentemente otros bienes y ordenarlos jerárquica y teleológicamente para garantizar su producción. Ejemplificamos cómo la universidad pública y la Iglesia católica, colectivos humanos orientados al bien común trascendente, pueden construir una propuesta alternativa anclada en una base de cooperación entre las comunidades.
Implicaciones deleuzianas para una teoría spinozista del tiempo
Authors: León Eduardo
Published: October 2022

El objetivo de este artículo es examinar la cuestión del tiempo, la duración y la eternidad en Spinoza a la luz de la filosofía deleuziana. En este sentido, primero, miraremos más de cerca lo que dice la Ética sobre este tema, y luego se formularán algunas observaciones que hace Deleuze sobre Spinoza y la duración. Al hacer esto se verá que, aunque las esencias son eternas, no son atemporales, sino que existe una dinámica interna con otras esencias de las que no puede entenderse sin referencia al tiempo. Finalmente, se analizará las interpretaciones que hace Deleuze sobre las esencias en Spinoza para pensar una teoría spinozista del tiempo y la eternidad.
Apuntes filosóficos sobre rostro, deseo y subjetividad
Authors: Segura Gutiérrez José Miguel , Romero Rodríguez Diana Karina
Published: October 2022

Este artículo explora desde una perspectiva filosófica la forma como la rostricidad está asociada al deseo y producción de subjetividad. De ahí que el campo de interés se centre en cómo dichas categorías tensionan la constitución subjetiva de los sujetos, a tal punto que inciden en la proyección de su propio trayecto biográfico. Esto a partir de algunos planteamientos teóricos acuñados por filósofos como Foucault, Deleuze y Guattari, con respecto al papel del rostro como productor de significado cultural en la gestión de la economía del deseo. Con miras a ambientar el texto, se tomará como recurso a Catarino, personaje de la novela Cien años de soledad, de Gabriel García Márquez.

Authors: García-Tudela Pedro Antonio
Published: October 2022

La igualdad de género continúa estableciéndose como un horizonte común para todos los países. De esta forma, la coeducación se convierte en una necesidad social, ya que es una de las oportunidades que existen para concienciar sobre la igualdad desde las primeras etapas educativas. El objetivo de este trabajo es presentar el diseño y la implementación de una propuesta de innovación coeducativa. Concretamente, el proyecto se ha implementado con todos los cursos de un centro educativo de Infantil y Primaria (61 estudiantes). Se ha hecho uso de la gamificación y el aprendizaje servicio. Concretamente, se han implementado un total de 32 sesiones sobre igualdad de género a través de las que se han trabajado contenidos curriculares y se han potenciado diversas competencias transversales. Para hacer posible la iniciativa se ha completado una campaña de crowdfunding. En relación con los resultados del proyecto, se consiguió la financiación necesaria para el alcance de los objetivos, se grabó profesionalmente una canción y se rodó un videoclip a través del que motivar a otras comunidades educativas. También se ha logrado trabajar la igualdad de género de manera cotidiana y se ha compartido libremente el diseño del proyecto. En relación con las debilidades, cabe destacar la temporalización, puesto que se tuvo que ampliar el calendario original. Por otro lado, se propone la aplicación de iniciativas similares para trabajar la diversidad de género, familiar y otros contenidos relacionados. Por último, se ofrecen recomendaciones para desarrollar una investigación a partir de la experiencia implementada.

A Double Salt Formation from Seawater Bittern and Ammonium Sulfate
Authors: Le Tam Minh , Pham Phuong Thi Hong , Hoang Nam Dong
Published: October 2022

Seawater bittern, a huge reserve containing numerous mineral materials, is an essential source for producing various industrial salts. In this work, the formation of a double salt between magnesia abundant in the seawater bittern and ammonium sulfate was studied via SEM and EDX analyses. In the next step, to optimize the efficiency of the double salt separation, the effects of technological parameters such as concentration of reactants and their ratio, as well as reaction time and temperature, were investigated. Afterward, the design of the experimental method was utilized to quantify the influence of these parameters. Based on the validation of the obtained model according to statistical criteria, only the ratio of reactants and reaction time have been shown to have decisive roles in the yield of the double salt recovery. The optimal yield reached a value of about 95%, demonstrating the feasibility of the applied technique for further processes, i.e., industrial production.
Individual Characteristics and Punitive Practice for the Women Accused of Illegal Possesion and Distribution of Drugs or Psychoactive Substances
Authors: Jarutienė Liubovė
Published: October 2022

According to the official statistical data, in Lithuania, female offenders make up approximately 10% of the convict population and 5% of the prison population (Department of Statistics, 2022). Due to rather small numbers of women drawn into the criminal world, female offenders and their specific needs are often hardly visible to the representatives of the law enforcement and correctional system. Therefore, the punitive practices applied to female offenders as well as the social context of their criminal behavior remain understudied topics in Lithuania. The main purpose of this study is to uncover the individual characteristics and the offending circumstances of the women accused of illegal posession and distribution of drugs. Also, this study includes the analysis of the sentencing trends for female culprits of drug-related crimes. The analysis of court practice and the interviews with the sentenced women has shown that, compared to males, females had no stable source of income and had to take care of the children and other family members more often. In addition, unlike males, females did not distribute drugs in the organized criminal groups, while the additional offences were mostly related to drug abuse rather than any other complicated criminal scheme. Finally, the comparison of sentencing trends has shown that Lithuanian courts tend to be more merciful towards women as they where imposed with shorter prison sentences. This study is one of the few attempts to explore the social context of female criminal behavior which will hopefully encourage to individualize the sentences imposed to female offenders.

Introducción: El diagnóstico rápido y definitivo con identificación del patógeno es fundamental cuando hay una infección periprotésica. La secuenciación de próxima generación permite identificar el ADN en un germen determinado en poco tiempo. Hasta donde sabemos, no hay reportes sobre su empleo para el manejo de la infección periprotésica en Sudamérica. Nuestro objetivo fue demostrar la viabilidad diagnóstica de las muestras obtenidas de una serie de pacientes operados en Buenos Aires, Argentina, y analizadas con la técnica de secuenciación de próxima generación.

Materiales y Métodos: Se analizó a una serie prospectiva de 20 pacientes sometidos a cirugía de revisión séptica y aséptica de cadera desde diciembre de 2019 hasta marzo de 2020. Se obtuvieron muestras intraoperatorias de líquido sinovial, tejido profundo y canal endomedular, que fueron enviadas para su análisis al laboratorio NexGen Microgen.

Resultados: Se seleccionaron 17 pacientes, porque tenían una muestra apta para analizar. Los resultados se recibieron dentro de las 72 h de la cirugía. En un caso, el resultado de la secuenciación de próxima generación informó un germen distinto del identificado en los cultivos posoperatorios de partes blandas, esto permitió corregir la antibioticoterapia. En otro, esta técnica identificó Parabacteroides gordonii en una revisión aséptica, en otro, Morganella morganii, a partir de cultivos negativos en una revisión en un tiempo.

Conclusión: Se demostró la viabilidad diagnóstica con la secuenciación de próxima generación, se pueden obtener resultados de microorganismos patógenos dentro de las 72 h posteriores a la cirugía en pacientes con infección periprotésica y cultivos negativos.
Uma proposta de sequência didática para o ensino fundamental usando a Pedagogia Histórico-Crítica
Authors: Feitosa Raphael Alves , Praciano Jaírla Bianca Aires
Published: October 2022

O ensino de ciências da natureza, frequentemente, é abordado com o emprego acentuado do livro didático, que direciona para a memorização de conceitos e aquisição de saberes fragmentados. Nesse sentido, as Sequências Didáticas (SD) podem ser ferramentas teórico-metodológicas úteis para contribuir no processo de construção da aprendizagem. Assim, o objetivo deste trabalho foi descrever uma proposta de SD para o ensino de Ciências da Natureza, tendo como mote a obra literária Krasnaya Zvezda (Estrela Vermelha), com uso de atividades educativas articuladas pela Pedagogia Histórico-Crítica (PHC) e foco no 9º ano do ensino fundamental. A SD proposta neste estudo é estruturada em quatro encontros que relacionam os aspectos da PHC, trechos do livro Estrela Vermelha, conteúdos de Ciências e as habilidades da Base Nacional Comum Curricular. Diante da análise da obra, foi possível constatar a articulação benéfica de arte-ciência e seu caráter interdisciplinar com conceitos associados às Ciências da Natureza, Humanas e Linguagens. Dessa forma, espera-se que esta proposta de SD possa auxiliar na resolução de problemas de ensino e aprendizagem que circundam a área de Ciências da Natureza.

Background and aims

Mental disorders with high levels of impulsivity such as bulimic spectrum eating disorders (BSED) and gambling disorder (GD) are associated with high risk of suicidal behavior. The aim of the present study was to identify the common and differential vulnerability factors behind suicide attempts in a sample of patients with BSED compared to patients with GD.

Methods

A total of 6,077 adults who sought treatment and met criteria either for BSED (n = 2,391) or GD (n = 3,686) were assessed at a specialized hospital unit. Personality traits, psychopathological symptomatology, lifetime history of suicide attempts and socio-demographic variables were evaluated.

Results

The prevalence of suicide attempts was higher for BSED patients (26.2%) compared to GD patients (7.1%) being anorexia nervosa (Binge/Purge type) and bulimia nervosa the most affected subtypes. In the predictive model, the transdiagnostic vulnerability factors with the highest contribution to the risk of suicidal behavior both in BSED and GD were unemployment, early age of onset of the disorder, worse psychopathological state, and self-transcendence personality trait. However, specific risk factors for suicidal acts were identified in each disorder: longer duration of the disorder, lower education levels and reward dependence were exclusively associated with BSED while female gender, older age, and higher harm avoidance were associated with GD.

Discussion

Patients with GD and BSED share certain vulnerability factors although certain factors are exclusive to each disorder.

Conclusions

Interventions need to pay special attention to both common and specific vulnerability factors to mitigate the risk of suicidal acts in these disorders.
Punks and profiteers in the war on death
Authors: Boss Jacob A
Published: October 2022

The genre of transhumanism known as biohacking, or the human augmentation movement, is rooted in a history of medical and scientific developments in the service of religious nationalism, where the perfection of the American body is advanced as a patriotic duty and symbol of the superiority of the American nation. Some participants in the biohacking scene advocate for a classic global rehabilitation project in the tradition of UNESCO, a post-war project of global salvation through collective evolution and science literacy. This vision contrasts sharply with separatist and grassroots biohacking projects. I introduce a model of ‘punks and profiteers’ to investigate two broad genres of biohacking: Corporate Medical Futurism and the DIY biohacker movement. Both strands rely on the fruits of the post-WWII boom in prosthetics, plastic surgery, and drug therapies, fruits well watered by religious and nationalist imperatives. Exploring the war on death led me to the grinder punk biohacking movement, which troubles the dominant view on transhumanism with their delight in human existence, taking limited interest in, or even demonstrating hostility toward, immortality, and rejecting ideas of finding salvation in escape from nature, the human body, and the earth.
On the Korean optative constructions -essumyen and -kilul from grammaticalisation and pragmatics perspectives
Authors: Yae Sunhee
Published: October 2022

Korean has diverse expressions denoting “wishes”. Among them, this paper focuses on the periphrastic constructions of [-essumyen/-kilul + desiderative verbs], excluding the construction [-ko siph-]. Using the perspectives of grammaticalisation and pragmatics, the developmental paths of how the elliptical constructions -essumyen and -kilul realise the concept of the “wish” of the speaker in the optative mood are investigated. This paper will clarify the evolution of the optative markers of -essumyen and -kilul using the mechanisms of grammaticalisation and pragmatic strategies including specialisation, subjectification, intersubjectification, politeness, insubordination, and pragmatic inferences. The SFP (sentential final particle) optatives -essumyen and -kilul take stance-related functions, undergoing insubordination and inviting pragmatic inferences. A corpus analysis will provide usage-based implications of the constructions.
Why impolite
Authors: Chen Rong
Published: October 2022

Impoliteness has thrust itself onto the centre stage of politeness research as well as the general area of pragmatics. Attention has been given, in recent decades, to various aspects of impoliteness: how it is linguistically and pragmatically realised, in what speech situations it is found, and by whom it is (or should be) evaluated. However, there has not been much explicit discussion in the literature on why speakers would choose to be impolite, although the functions of specific instances of impoliteness are frequently discussed. In this paper, I propose that impoliteness is largely motivated by self-politeness.
Language reproduction and coordinated agency through resonant play
Authors: Takanashi Hiroko
Published: October 2022

This article examines how creativity is jointly achieved in playful Japanese conversations, focusing on dialogicality in language form, meaning and the speaker’s agency. The analysis employs “dialogic syntax” and “stancetaking” as the theoretical frameworks of dialogicality and shows that dialogic engagement in talk-in-interaction engenders resonance, creating both similarities and contrasts in parallel structure across utterances. This study points out that such differentiations come from distinctive social actors situated in the indexical field of social life. Injecting stancetaking into dialogic syntax makes it possible to explicitly address the dialogic creation of socially meaningful language reproduction in tandem with constructing the stancetaker’s agency. Moreover, dialogic syntax and stancetaking shed important light on how a playful utterance creates priming effects, prepatterning the subsequent language reproduction in resonance, and prompting stancetakers’ affect to voluntarily contribute something new, engaging with the prior utterances, which develops the play framing activity and enhances shared pleasure.
Mayhem, Madness and Distorted Mirrors in Herrmann’s Music for Hitchcock’s Psycho
Authors: Moreira Daniel
Published: October 2022

Bernard Herrmann’s music for Hitchcock’s Psycho plays a crucial role in implementing the relentless move towards mayhem and madness which is characteristic of this film, as well as in creating distorted reflections between sanity and madness. In this article, I claim that the former aspect is expressed by a gradual move from tonal towards “mistuned” and then atonal harmonic objects, while the distorted mirror relationship is suggested by a number of subtle correspondences (both similarities and differences) between cues associated with Marionand cues associated with Norman. My analysis rests on both intratextual and intertextual factors. While I reveal the former through a close analysis of the film score in relation to the narrative, I discuss the latter in terms of Herrmann’s general approach to film music, the conventions of horror film scoring, and the special linkage between modernist music and madness in concert music, opera and cinema.
Max Steiner and Extended Tonality
Authors: Stokes Jordan Camalt
Published: October 2022

Since the revitalization of film music studies in the 1980s, the field has been dominated by musicological approaches, with music theory and analysis taking a back seat. As a result, film music scholars lack a common set of techniques for grappling with the harmony, rhythm, form, and melody of film music cues. But this situation is beginning to change: recent research by Frank Lehman and Scott Murphy offers powerful new tools for thinking about film music harmony. The purpose of this essay is to test the systems developed by these theorists against the music of Max Steiner, hopefully contributing to the development of a share analytical vocabulary for film music, and deepening our understanding of Steiner’s compositional technique.
Ексергетичний аналіз процесів енергозбереження в газотранспортній системі

Впровадження технологій енергозбереження в газотранспортній системі при альтернативній заміні енергетично неефективного процесу зниження тиску газу в дросельно-редукційних установках на його адіабатичне розширення в турбодетандерних агрегатах з виробництвом електричної енергії дозволяє суттєво зменшити ексергетичні втрати. Утилізація надлишкового тиску природнього газу в утилізаційних турбодетандерних агрегатах (УТДА) може ефективно використовуватись для генерації електричної енергії, виробництва холоду та скраплення природнього газу на компресорних станціях в системі транспорту , розподілу та споживання газу. Застосування ексергетичного методу при термодинамічному аналізі УТДА дозволяє враховувати, так звані, транзитні потоки ек­сер­гії, розраховувати кількісні та якісні характеристики енергетичних перетворювань з визначенням їх рівня необоротності в абсолютних та відносних показниках. Проведені розрахунки ексерге­тич­них характеристик одноцільового та когенераційного турбодетандерних агрегатів показують, що ексергетичний ККД одноцільового електрогенеруючого УТДА з підігрівом є вищий по відношенню до коогенераційної схеми без попереднього підігріву газу, що обумовлюється суттєвим впливом температури підігріву газу на електричну потужність по відношенню до ексергії теплоти підігріву. Порівняння ексергетичних показників одноцільових УТДА з підігрівом газу до та після детандеру показує, що установки з підігрівом перед детандером є більш ефективними, незважаючи на те, що піді­грів після розширення, в принципі, може здійснюватись за рахунок теплової енергії навколишнього середовища. Загалом практична доцільність енергозбереження на основі УТДА визначається на основі мінімальних суспільно-необхідних витрат, які включають усі види затрат, які пов'язані з практичним впровадженням агрегатів та їх експлуатацією
Комерційний холод як компонент тригенерації розподіленої енергетики
Authors: Морозюк Л.І. , Басов А.М.
Published: October 2022

В статті представлено принцип створення схемного рішення системи тригенерації із заздалегідь заданим джерелом енергії та споживачем холоду і тепла. Вирішення проблеми енергозбереження та одночасного підвищення енергоефективності процесів виробництва тепла та холоду ґрунтується на концепції тригенерації в системі розподіленої енергетики. Роль розподіленої енергетики полягає у зменшенні глобальної енергетичної проблеми, що полягає у енергозабезпеченні віддалених від великих регіонів населення. У якості конкретного споживача виступає комерційний холод, що безпосередньо вирішує продовольчу проблему для людства, забезпечуючи життєво важливими продуктами харчування та питною водою відповідно до фізіологічних норм. Наведено спосіб створення системи «комерційний холод – розподілена генерація енергії» через оцінки технічної системи за комплексом факторів (економічного, енергетичного, екологічного та соціального) для місцевості та статусу комерційного підприємства. За цими даними визначаються джерело енергії та продуктивності підприємства з холоду та тепла, вибираються способи відведення тепла до зовнішнього середовища, розробляються заходи, що спрямовані на зменшення незворотних втрат у системі. Виконуються розрахунки елементів з оцінкою ефективності за енергетичним, економічним, екологічним та соціальним факторами. Рішення про доцільність застосування тригенерації для конкретних споживачів з вибором робочих параметрів і характеристик елементів системи вимагає детального аналізу і збору даних щодо реальних величин енергетичної ефективності кожного елементу. Питання торкається аналізу впровадження одного з найбільш пер­спективних напрямків в енергозбереженні – використання екологічно чистих систем малої енергетики. Наведено приклад формування вихідних даних для створення системи тригенерації комерційного призначення з сонячною енергетично установкою, абсорбційною холодильною машиною та системою акумуляції тепла

Published: October 2022

In this study, titanium dioxide (TiO2) and titanium dioxide – activated carbon composite (TiO2–AC) were prepared by sol-gel method for photoelectrochemical (PEC) applications. Characterization of the materials was performed by scanning electron microscope, energy dispersive X-ray analysis, Fourier transform infrared spectroscopy, X-ray diffraction, and diffuse reflectance spectroscopy. The results show that TiO2 was successfully loaded on activated carbon (AC), producing TiO2–AC with 2.61 eV of bandgap energy, lower than that of TiO2 (3.15 eV). Photoanodes based on TiO2 and TiO2–AC were fabricated and applied to PEC experiments for phenol degradation. In comparison with the TiO2 photoanode, the TiO2–AC one exhibited superior photocatalytic activity, which was indicated by a high current density and effective phenol removal. A mechanism of phenol PEC degradation on the TiO2–AC photoanode was proposed, which includes interaction between protonated phenol and active sites bearing oxygen on the photoanode surface. A kinetic model according to this mechanism was also established and fitted to experimental findings, resulting in rate constants of elementary reactions.

PROGRESSIVE DAMAGE ANALYSIS OF STEEL-REINFORCED CONCRETE BEAMS USING HIGHER-ORDER 1D FINITE ELEMENTS
Authors: Nagaraj Manish H. , Maiaru M.
Published: October 2022

The present work investigates progressive damage in steel-reinforced concrete structures. An elastic-perfectly plastic material response is considered for the reinforcing steel constituent, while the smeared-crack approach is applied to model the nonlinear behavior of concrete. The analysis employs one-dimensional numerical models based on higher-order finite elements derived using the Carrera unified formulation (CUF). A set of numerical assessments is presented to study the mechanical response of a steel-reinforced notched concrete beam loaded in tension. The predictions are found to be in very good agreement with reference experimental observations, thereby validating the numerical approach. It is shown that CUF allows for the explicit representation of the constituents within the composite beam, resulting in accurate solutions in a computationally efficient manner.

Authors: Vargas-Larreta Benedicto , Amezcua Rojas Mayra , López-Martínez Jorge Omar , Cueto-Wong Antonio , Cruz-Cobos Francisco , Nájera-Luna Juan Abel , Aguirre-Calderón Cristóbal Gerardo
Published: October 2022

Antecedentes: Los almacenes de carbono (C) de los bosques del mundo ascienden a 861 Pg; 44 % se encuentra en el suelo. A pesar de su importancia como reservorio, los estudios sobre carbono orgánico en el suelo (COS) en los bosques de México son escasos.
Pregunta: ¿El carbono orgánico en el suelo varía entre tipos de vegetación y tipos de suelo en los bosques de Durango?
Sitio de estudio: Bosques templados de Durango, México.
Métodos: Los datos de COS se obtuvieron de 399 sitios permanentes. Se colectaron muestras de hojarasca, horizonte de fermentación y de las capas de suelo de 0-30 y 30-60 cm. Los contenidos de C se determinaron en un analizador elemental. El cálculo de las incertidumbres se realizó siguiendo los procedimientos usados por la Comisión Nacional Forestal.
Resultados: El COS promedio estimado fue 8.48, 1.08, 110.62 y 53.44 Mg ha-1 en hojarasca, horizonte de fermentación, suelo de 0-30 y de 30-60 cm, respectivamente. Los almacenes promedio de C total en el suelo oscilaron desde 26.34 hasta 578.27 Mg ha-1 (incertidumbre: 6.31 %). La mayor variabilidad de los almacenes de COS se presentó en el bosque de pino.
Conclusiones: El tipo de bosque no influye en los almacenes de carbono orgánico en el suelo, pero sí el tipo de suelo. Los reservorios de COS en los bosques Durango son más altos comparados con el mismo tipo de vegetación en otras regiones del país.
Modelling of the Weighted Average Funding Cost of the CBRT: LNV-ARMA Approach
Authors: CANPOLAT Şiyar
Published: October 2022

In this study, we model the monthly time series of the Central Bank of the Republic of Turkey’s Weighted Average Funding Cost (Interest Rate) for the period between 2011:01-2020:12. In this framework, we establish and compare the linear and the nonlinear based various autoregressive (integrated) moving average models in two separate groups and investigate the most suitable model for the series. After all, we reveal that the relevant interest rate series can be modelled best with the LNV-ARMA(2,1) model for the related period. The first novelty of this study is that we model the relevant interest rate itself instead of investigating the relationship of this interest rate with the other macroeconomic variables. The second novelty of this study is that we circumvent the unit root problem and establish a more explanatory time series model by applying the LNV methodology.
