Proenkephalin A as a marker for glomerular filtration rate in critically ill children: validation against gold standard iohexol GFR measurements
Authors: Smeets Nori J.L. , Hartmann Oliver , Schulte Janin , Schreuder Michiel F. , de Wildt Saskia N.
Published: October 2022

Objectives

Accurate determination of glomerular filtration rate (GFR) is important. Several endogenous biomarkers exist for estimating GFR, yet, they have limited accuracy, especially in the paediatric population. Proenkephalin A 119–159 (PENK) is a novel and promising GFR marker, but its relation with age in children remains unknown. Also, the value of PENK has never been validated against measured GFR (mGFR) in children when compared to traditional GFR markers including serum creatinine (SCr), SCr-based estimated GFR (eGFR) and cystatin C (cysC).

Methods

Critically ill children and term-born neonates were included in this single-centre, prospective study. Iohexol-based mGFR, SCr, and cysC were determined in each patient. eGFR was calculated using the bedside Schwartz equation, incorporating SCr and height. Spearman correlation coefficients were calculated to determine the correlation between mGFR and PENK, SCr, cysC and eGFR.

Results

For 97 patients (56 children and 41 neonates), mGFR, SCr, cysC and PENK levels were available. PENK levels were higher in young children and decreased to adult PENK reference values around two years of age. PENK levels were highly correlated with mGFR (ρ=−0.88, p<0.001), and similar to mGFR–eGFR correlation (ρ=−0.87, p<0.001). For cysC and SCr the correlation with mGFR was lower (ρ=−0.77 and ρ=−0.46, respectively. Both p<0.001).

Conclusions

The correlation of PENK with mGFR was as good as SCr-based eGFR-mGFR correlation. To determine the added value of PENK in paediatric clinical care and prior to implementation, PENK reference values are needed and the development and validation of a paediatric PENK-based eGFR equation is necessary.
Fractal analysis of structural characteristics and prospecting of the Luanchuan polymetallic mining district, China
Authors: Cui Zhongliang , Huang Eugene , Liu Guanghua , Chen Hao , Guo Xinyu
Published: October 2022

The Luanchuan polymetallic mining district (LPMD) covers many major deposits of the East Qinling metallogenic belt in Henan Province, central China. It has attracted much attention because of its various types of minerals, abundant mineral reserves and huge metallogenic potential. Systematic research on the geology of LPMD has been carried out previously, and it is concluded that the formation of the ore deposits is dominantly controlled by fault structure. However, there are few reports on the quantitative characterization of fault structure and spatial distribution of deposits and the coupling relationship between them. This study applies fractal theory to the illustration of the characteristics of inter-relationship between fault structure and spatial distribution of the ore deposits in LPMD, which then may serve as a basis for further ore exploration. Our results indicate that the capacity dimension (CPDs) of integrated fault structure, NW-trend fault and NE-trend fault for the area investigated are 1.7206, 1.6539 and 1.2145, respectively; while the information dimension (IND) of which is 1.7143, 1.6559 and 1.2222, respectively. The studied area has superior geological environment for potential ore deposits, with major contribution from the NW-trend fault. Spatial distribution dimension value of metallic ore is 0.8873. Quantity fractal dimension and Density fractal dimension values of the metallic deposits are 1.1154 and 1.115, respectively. Quantitatively, the main ore deposits discovered in this area mainly fall on either CPD ≥ 1.49, IND ≥ 1.38 or 1.49 > CPD ≥ 1.00, 1.38 > IND ≥ 1.00. Qualitatively, conditions that facilitate ore deposits require higher fractal dimension values. Among the areas studied, we found that Rank I area is the most ideal region that fulfilled the quantitative and qualitative conditions, which is consistent with the actual location of the ore deposits discovered.

Approximate controllability results in α-norm for some partial functional integrodifferential equations with nonlocal initial conditions in Banach spaces
Authors: Ndambomve Patrice , Kpoumie Moussa El-Khalil , Ezzinbi Khalil
Published: October 2022

In this work, we discuss the approximate controllability of some nonlinear partial functional integrodifferential equations with nonlocal initial condition
in Hilbert spaces. We assume that the corresponding linear part is approximately controllable. The results are obtained by using fractional power theory and α-norm, the measure of noncompactness and the Mönch fixed-point theorem, and the theory of analytic resolvent operators for integral equations. As a result, we obtain a generalization of the work of Mahmudov
[N. I. Mahmudov,
Approximate controllability of evolution systems with nonlocal conditions,
Nonlinear Anal. 68 2008, 3, 536–546],
without assuming the compactness of the resolvent operator. Our results extend and complement many other important results in the literature. Finally, a concrete example is given to illustrate the application of the main results.
Remarks on the Belitskii–Lyubich and discrete Markus–Yamabe conjectures
Authors: Sart Frédéric
Published: October 2022

In this paper we prove the Belitskii–Lyubich conjecture for triangular and gradient mappings. These results resemble those obtained for the discrete Markus–Yamabe conjecture. However, the proofs are quite different, which sheds new light on the subject. We complete the picture by showing that the general versions of the two conjectures can be turned into theorems at little cost, simply by relaxing their spectral condition.
Identification of a novel necroptosis-associated miRNA signature for predicting the prognosis in head and neck squamous cell carcinoma
Authors: Guan Jiezhong , Liu Xinyu , Wang Kang , Jia Yiqun , Yang Bo
Published: October 2022

Head and neck squamous cell carcinoma (HNSCC) is one of the most aggressive malignancies that have a poor prognosis. Necroptosis has been demonstrated in recent years to be a form of inflammatory cell death occurring in multicellular organism, which plays complex roles in cancer. However, the expression of necroptosis-related miRNAs and genes in HNSCC and their correlations with prognosis remain unclear. In this study, R software was used to screen differentially expressed miRNAs downloaded from The Cancer Genome Atlas. A prognostic model containing six necroptosis-related miRNAs (miR-141-3p, miR-148a-3p, miR-331-3p, miR-543, miR-425-5p, and miR-7-5p) was generated, whose risk score was validated as an independent prognostic factor for HNSCC. Target genes of the key miRNAs were obtained from TargetScan, miRDB, and miRTarBase, and 193 genes in the intersection of the three databases were defined as consensus genes. Kyoto Encyclopedia of Genes and Genomes and Gene Ontology analyses indicated that the composition of the tumor microenvironment as well as specific pathways may be closely related to necroptosis in HNSCC. Nine key genes were also obtained by the MCODE and cytoHubba plug-ins of Cytoscape: PIK3CD, NRAS, PTK2, IRS2, IRS1, PARP1, KLF4, SMAD2, and DNMT1. A prognostic model formed by the key gene was also established, which can efficiently predict the overall survival of HNSCC patients. In conclusion, necroptosis-related miRNAs and genes play important roles in tumor development and metastasis and can be used to predict the prognosis of HNSCC.
Mechanisms and influential variables on the abrasion resistance hydraulic concrete
Authors: Guo Jinjun , Gao Minghao , Wang Kun , Zhang Peng
Published: October 2022

Abrasion damage is inevitable for hydraulic structure concrete, to increase the service life of large water conservancies and to keep them running safely and reliably, hydraulic concrete requires a high abrasion resistance. This review synthesizes current practices defined by scientific literature in a format focused on allowing quick comparison and understanding of the current scenario of anti-abrasion concrete enhancing mechanism, measuring methods, and approaches to enhance concrete abrasion resistance. Besides, the review highlights the application of widely used materials and potential materials application, like silica fume and fibers which are mature research at present, and effective but preliminary used materials like nanoparticles, to better understand the development of higher abrasion resistance of concrete. According to the present research, it indicate that incorporating enhancement materials into concrete to achieve better abrasion resistance are basically through the way of hardening cement paste, controlling internal crack propagation, or using stronger coarse aggregate to enhance its ability for anti-abrasive. Finally, based on the systematic literature review, a discussion on major areas holding the significant potential to improve current practices is presented and practical recommendations are provided to advance toward more direct and optimized methods.
Topology and applications of 2D Dirac and semi-Dirac materials
Authors: Mondal Sayan , Ganguly Sudin , Basu Saurabh
Published: October 2022

Two dimensional (2D) Dirac materials, such as graphene, hold promise of being useful in energy storage, and thus have merged as candidates that are worth exploring through the last couple of decades. In this chapter, we mainly focus on three aspects of these materials, namely, the electronic properties, via computing the band structure, the topological properties through the topological invariants, and the prospects of these 2D materials for spintronic applications, via studying the spin polarized transport. All of these properties are correlated, and hence warrant a thorough discussion. Further, in order to ascertain whether a band deformation induces noticeable effects on the electronic, topological and spintronic properties, we have considered a 2D semi-Dirac system, that does not have Dirac cones, however the conduction and the valence bands touch at an intermediate to the Dirac points in the Brillouin zone. From our studies, we infer that the behaviour of these semi-Dirac systems is quite distinct from their Dirac counterpart. Finally, in order to have noticeable spin polarized transport, we use heavy adatoms (such as, Au) on the graphene matrix which enhances the spin–orbit coupling, and thereby propose a mechanism that will ramify on the spintronic applications.
Production of high value-added filler from harmful dust of marble industry using N-sodium lauroyl sarcosinate surfactant as a new flotation collector
Authors: Attia Hamada A. , Farghaly Mohamed G. , Saleh Abdel-Hady M. , Abdel-Khalek Mohamed A.
Published: October 2022

In the stone industry, about 73% of the total production is generated as solid waste. In the processing phase, only 20% is produced as harmful ultra-fine sawdust sludge. In the Turah area, Cairo, Egypt, an estimated 448,000 tons are produced annually. About 60% of the total production of dimension stones is carbonate stones. The objective of this study is to properly dispose of the ultrafine pollutants and produce value-added products. The ultrafine marble waste was characterized by different methods such as XRD, XRF, FTIR, particle size analysis and zeta potential. Calcite and dolomite minerals were the main constituents of this waste (91%). The average particle size was 6.656 µm. The fine fraction with a particle size of less than 25 µm contains 97.6% calcite with 81% weight. Sodium N-lauroyl sarcosinate (SNLS) was used as a selective flotation collector for calcite as a calcium mineral. A flotation concentrate with a purity of 99.6% and an overall yield of 80% was obtained at a pH of 9. The bleached product meets ASTM standard specifications for paint and paper applications.
Überbrückungsleistungen für EU-Bürger-/-innen in Deutschland: Instrument sozialer Absicherung oder Migrationskontrolle?
Authors: Bruzelius Cecilia , Ratzmann Nora , Reiß Lea
Published: October 2022

Der Artikel analysiert die sogenannten Überbrückungsleistungen (nach § 23 Abs. 3 SGB XII), welche in Deutschland lebende mittellose EU-Bürger/-innen, die keinen Rechtsanspruch auf Grundsicherung für Arbeitssuchende oder Sozialhilfe haben, für einen begrenzten Zeitraum als Übergangsgeld erhalten können. Die Leistung soll dieser Personengruppe eine minimale soziale Unterstützung für einen begrenzten Zeitraum, vornehmlich bis zur Ausreise aus Deutschland, bieten. Der Artikel analysiert die Umsetzung dieser Leistungen. Ziel ist ein Abgleich zwischen Intentionen des Gesetzgebers und gelebter Praxis sowie eine Diskussion der sozialpolitischen Folgen für Leistungsbezieher/-innen, die unter anderem durch die Verschränkung von Sozial- und EU-Freizügigkeitsrecht entstehen. Neben einem Überblick über die Gesetzlage und deren politischen Hintergrund gewährt der Artikel daher Einblicke in die Gewährungspraxis und Inanspruchnahme der Leistung. Die Ergebnisse der hierfür durchgeführten qualitativen Erhebung offenbaren unterschiedliche Praktiken und Umsetzungsdefizite, die auf einen Mangel an praktischen Erfahrungen, Rechtsunsicherheiten sowie bürokratische Hürden in der Antragsstellung zurückzuführen sind. Insgesamt kommt der Artikel zu dem Schluss, dass Überbrückungsleistungen, wie bereits im Gesetz angelegt, keine soziale Mindestabsicherung mittelloser EU-Bürger/-innen darstellen, auch wenn sie gelegentlich zur Überbrückung einer finanziellen beziehungsweise sozialen Notlage beitragen. Ferner wird durch die oft restriktive Umsetzungspraxis die Prekarisierung der Zielgruppe verstärkt, sodass Überbrückungsleistungen de facto eine Verschränkung von Sozialleistungsbezug und Migrationssteuerung darstellen und als Instrument der Migrationskontrolle im freizügigen Europa gewertet werden können.

Produktionslinien für Batterieelektroden bestehen aus hoch produktiven aber starren Prozessen. So können Änderungen nur langsam umgesetzt werden, und eine Reaktion auf neue Bedingungen ist kaum möglich. Im Projekt ReFlexBat (Regelbare Beschichtungseinheit für die flexible Beschichtung von Batterieelektroden) wird deshalb eine autonome Beschichtungseinheit entwickelt, um den Anfahrprozess zu beschleunigen, auf neue Randbedingungen zu reagieren und allgemein den Ausschuss im Beschichtungsprozess zu reduzieren. Bisher erfolgte zum einen die Erarbeitung des Konzepts, zum anderen wurde die notwendige Präzision zum Erreichen der Qualitätsziele bestätigt.
K. K. COVID-19
Authors: Farrell Natalie
Published: October 2022

The latest installment of Nintendo’s sim franchise, Animal Crossing: New Horizons, launched mid-March 2020, and it quickly transformed from an unassuming island-escape sim to a venue in which players constructed the COVID-19 pandemic as a cultural trauma and wrestled with its temporal effects. Drawing on the trauma-informed analytical frameworks developed by Maria Cizmic and Judith Herman, this article contends that Animal Crossing’s easy-listening soundtrack provides an aesthetic rhetoric through which players perform the pandemic’s traumatic effects. The repetitive soundtrack offers a psychological space for players to grieve while also enacting a sense of temporal regularity. Looped background music creates a Muzak-like affective environment that contributes to workplace nostalgia as players complete menial tasks. Further, music-centric events in the game’s local-level narrative dictate the speed at which the game is played, embodying the fragmentary temporal experience often attributed to the effects of trauma. Such a perspective traces the ways in which trauma theory has the potential to inform audience reception to video game music.
Passive Drag Reduction of the Square Back Truck Body
Authors: Omar Ashraf Ali , ALTAF ALAMAN , Asar Waqar
Published: October 2022

Drag is one of the most significant factors that increase fuel consumption, followed by operating cost of the vehicle. Square-back road vehicles like trucks and buses are common and popular means of transport across the globe. In this background, it is of great research value to reduce the drag on vehicles, improve their fuel efficiency and reduce their operational cost. In this work, a simplified model of a truck was considered, and its drag was reduced by modifying its geometry using passive drag reduction devices. The passive devices used in this study were backward-facing step, fins, splitter plates/tabs, dimple, vents, and channels. These devices, of different sizes and configurations, were numerically studied using CFD software Star CCM+ at a Reynolds number of 2.4127×10^6. Drag reduction up to 9.9% was achieved, when backward-facing step was placed at the bottom rear edge of the truck. Further, multiple circular channels used on the truck’s sides reduced the drag up to 6.5%, while multiple rectangular channels on the sides of the truck achieved 5.1% drag reduction. The maximum drag reduction of the fins was found to be 4.6%. In spite of these, no significant drag reduction was observed when using splitter plates/tabs, dimple and vents.
Energy Optimization for Milling 304L Steel using Artificial Intelligence Methods

Published: October 2022

With increased production and productivity in modern industry, particularly in the automotive, aeronautical, agro-food, and other sectors, the consumption of manufacturing energy is rapidly increasing, posing additional precautions and large investments to industries to reduce energy consumption at the manufacturing system level. This research proposes a novel energy optimisation using a response surface methodology (RSM) with artificial neural network (ANN) for machining processes that saves energy while improving productivity.The feed rate was discovered to be the most influential factor in this study, accounting for 84.13 percent of total energy consumed. Furthermore, it has been established that as the material removal rate (MRR) increases, energy efficiency (EE) declines. This optimization of cutting conditions gives us the optimal values of cutting speed Vc = 129.37 m/min, feed rate f = 0.098 mm/rev and depth of cut ap = 0.5 mm. This approach will allow us to decrease the total energy consumed (Etc) by 49.74 % and increase the energy efficiency (EE) by 13.63 %.
Motion Planning and Tracking Trajectory of an Autonomous Emergency Braking Pedestrian (AEB-P) System Based on Different Brake Pad Friction Coefficients on Dry Road Surface
Authors: Zulkifli Abdullah , Peeie Mohamad Heerwan , Zakaria Muhammad Aizzat , Ishak Muhammad Izhar , M.A. Shahrom  , B. Kujunni
Published: October 2022

Accidents between vehicles and pedestrians usually occur when a pedestrian is crossing the road. An Autonomous Emergency Braking Pedestrian (AEB-P) is introduced to prevent collisions between vehicles and pedestrians. However, the performance of an AEB-P will be reduced when the brake pad is worn out on a dry road. In this study, the motion planning, namely Vehicle Conditional Artificial Potential Field (VC-APF), including a warning signal and emergency brake phase that generate the vehicle’s deceleration, is proposed to analyze the effect of brake pad on the AEB-P performance. Then, the vehicle’s deceleration is tracked by the tracking trajectory, where the PI controller is adapted to provide the optimum braking force. The function of PI control is to ensure the vehicle’s deceleration is approaching the desired deceleration. The performance of the proposed method has been simulated on the dry road surface with different brake pad coefficients; 0.4, 0.35, and 0.24. The simulation results show that the vehicle manages to stop colliding with a pedestrian on the dry road surface at the minimum safety distance range of 2.7-2.9 meters.
Avatares del sujeto cartesiano
Authors: Espinosa Proa Sergio
Published: October 2022

El sujeto cartesiano se constituye en la subordinación de todas las facultades a la inteligencia; ella ha de imponer en todo momento y situación sus condiciones, porque de lo que se trata es de asegurar el dominio de las cosas, algo que no se consigue sin interponer al deseo, a ese deseo, un entendimiento adecuado. Y Descartes sabe muy bien que no hay entendimiento que no sea de objetos. Los seres humanos están dotados de estas facultades, que habitualmente chocan y no dejan de entrar en conflicto. En la sustitución de la confusión (y la superstición) por el método, Descartes lleva a su extremo la sujeción de las demás facultades por el entendimiento, injusticia que sublevará a muchos. En este artículo se aborda este problema.
Lenguaje y metafísica: los problemas de la filosofía analítica
Authors: Santamaría Velasco Freddy
Published: October 2022

En Mi visión de la filosofía, Friedrich Waismann afirma que un verdadero problema filosófico radica, no en darle solución, sino en encontrarle sentido, de modo que la tarea de la filosofía está en suministrar comprensión. Esto no sería posible si quien se hace una pregunta no da un giro en su manera de pensar para ver las cosas de modo distinto. Con esto en mente, para ayudarle a quien pregunta a dar este giro es necesario orientarlo con el fin de que cruce la brecha de la demostración: hay que darle una discusión, no una prueba; es decir, no debe hostigársele pidiéndole que dé una respuesta, sino que debe pedírsele que considere pacientemente su pregunta. La intención no es, pues, resolver un problema, sino cambiar la actitud de quien pregunta, de lo cual se espera que se disuelvan los falsos problemas y, con base en enunciados claros y bien construidos, la filosofía pueda avanzar en sus argumentos de alguna forma.
Cambio de rol docente y emociones identificadas en experiencias de escape room
Authors: Corrales Serrano Mario , Dávila García María Jesús , Cifuentes Martín Magdalena , Izquierdo Donoso María
Published: October 2022

La irrupción de las metodologías activas ha ido transformando el rol docente en el proceso de enseñanza-aprendizaje. Dentro de estas metodologías, actividades de gamificación como las escape room educativas tienen una incidencia especial en el papel del docente ya que, además de inducir a que el profesorado desempeñe un papel menos protagonista y más secundario, generan una serie de emociones diferentes a las predominantes en el docente. El presente estudio tiene como objetivo conocer el rol docente y las emociones experimentadas en experiencias educativas tipo escape room. La metodología de investigación ha consistido en la recopilación de información a través de un cuestionario elaborado ad hoc, con cuestiones en escala Likert 1-5. El cuestionario consta de dos partes: una en la que se recopila información sobre el rol desempeñado por los y las docentes en ese tipo de actividades y otra en la que se exponen las emociones identificadas por el profesorado. En el estudio han participado 139 docentes de todas las etapas educativas. El análisis cuantitativo de resultados revela un cambio de rol docente en estas experiencias didácticas, caracterizado por una actitud mediadora, observadora y controladora, y por experimentar mayoritariamente emociones como miedo, alegría, satisfacción y orgullo.

Published: October 2022

Introducción. El reemplazo total de cadera (RTC) es la artroplastia mas exitosa hasta el momento, sin embargo no esta exenta de complicaciones, como la inestabilidad protésica. Las copas de doble movilidad (DM) constituyen una opción de tratamiento en la resolución del RTC con luxaciones recidivantes por inestabilidad. El objetivo del estudio fue evaluar resultados del cementado de un componente DM en un cotilo previo no cementado estable, en una paciente con luxación recurrente, sometida a RTC de revisión como alternativa a un inserto constreñido. Material y métodos. Paciente con RTC no cementado de fijación distal, después de osteosíntesis fallida, que presentaba episodios de luxaciones recurrentes, tratada con revisión con implante de DM cementado dentro de cotilo primario no cementado fijo y el uso de un modulo femoral proximal con offset extendido, preservando tensión, longitud y reductibilidad de la prótesis, obteniendo buenos resultados a mediano plazo. Resultados. Se logró la resolución de la inestabilidad protésica sin presentar mas episodios de luxación. Se evaluó la evolución mediante el score de Harris modificado. Conclusión. La cementación de un cotilo DM en una copa previamente bien fijada parece ser una opción viable para tratar y prevenir la inestabilidad después del RTC de revisión.

Published: October 2022

Introducción: El objetivo de este estudio fue analizar los resultados clínicos, radiográficos y funcionales en pacientes <20 años sometidos a artroplastia total de cadera con vástago femoral tipo 2B corto no cementado.
Materiales y Métodos: Se realizó un estudio retrospectivo de 13 pacientes (16 artroplastias totales de cadera) operados entre enero de 2006 y enero de 2021. La edad media y el índice de masa corporal eran de 16.5 ± 2.5 años y 22,74 ± 4,06 kg/m2, respectivamente. El seguimiento medio fue de 43.3 meses (rango 12-128, DE ± 33.45). Se analizaron las indicaciones quirúrgicas, y los resultados funcionales y radiográficos. La supervivencia del implante se calculó con la estimación de Kaplan-Meier.
Resultados: La indicación predominante fue necrosis avascular (9/16 caderas [56%]), el 66% estaba asociada al uso prolongado de corticoides. El HHS para cadera mejoró significativamente de 33 ± 16,5 a 94 ± 5,6 (p <0,001). Diez (76%) pacientes usaban dispositivos de asistencia para caminar antes de la artroplastia, pero ninguno los necesitaba al final del seguimiento. Se observó radiolucidez en un componente acetabular sin repercusión clínica hasta el final del seguimiento. No se registraron signos radiográficos de aflojamiento del componente femoral. La supervivencia del implante fue del 100% hasta el final del seguimiento.
Conclusiones: La artroplastia total de cadera primaria con un vástago femoral corto no cementado en pacientes <20 años con artrosis avanzada de cadera logró resultados equiparables a los ya publicados, con la particularidad de que es un procedimiento menos invasivo y ahorra capital óseo femoral.

Study on antioxidant activity of chicken plasma protein hydrolysates
Authors: Wang L.P. , Wang Z.F. , Reziwangul S. , Chen S.E.
Published: October 2022

This study optimised the hydrolysis process of chicken plasma protein and explored the in vivo antioxidant activity of its hydrolysates. The results showed that alkaline protease provided the highest degree of hydrolysis (19.30%), the best antioxidant effect in vitro. The optimal hydrolysis process of alkaline protease was: temperature 50 °C, time 8 h, [E]/[S] 7000 U g−1, pH 7.5. Antioxidant studies in vivo showed that the low, medium, and high dose groups significantly reduced the serum MDA and protein carbonyl content (P < 0.05) and significantly increased the serum SOD and GSH contents (P < 0.05). The results of HE staining of the liver showed that the liver cells in the model group were severely damaged, but the chicken plasma protein hydrolysates could alleviate this pathological damage.

Hungarian pond fish production is based on grains, but in the last few years, new ideas and efforts have appeared to intensify carp production technology. The basic objective was to change grain-based feeding to nutritionally complete feeds, which ensure rapid growth and more efficient feed conversion rates. This study aimed to utilise empty ponds during the summer period for carp production. Thus, there is no need for fish producers to catch fish in large ponds at the operating water level to satisfy smaller market demands appearing during the summer.

The other aim was to compare the meat quality of fish raised on traditional and nutritionally complete feed until market size in the last year of production. Fatty acid profile and the levels of saturated, monounsaturated, and polyunsaturated fatty acids in fish fillets were specified, and their ratios were analysed. The result showed that nutritionally complete feed with different fatty acid composition affects the fatty acid composition of carp fillet during the rearing period. Quality of the fillet of carp fed with higher unsaturated fatty acid content became more favourable to the consumers due to health promoting effect of polyunsaturated fatty acids.
Learning Japanese interactional particles through a usage-based and concept-based language instruction
Authors: Masuda Kyoko
Published: October 2022

The purpose of the current study is two-fold. First, this paper aims to uncover the three-year acquisition process of three interactional particles, ne, yo, and yone by three Chinese-speaking learners of Japanese in a corpus. Among the three particles, yone appeared the latest after one year of study abroad, and the learners progressed in their usage by trying to share epistemic stance and assessments by using yone. However, understanding the epistemic stance for the speaker’s world is challenging. Second, this paper supports the integration of usage-based approaches and sociocultural theory. For teaching interactional particles effectively in the classroom, understanding of the role of intersubjectivity in discourse is crucial. This paper proposes three sets of schematic visual representations for core meanings of ne, yo, and yone, which is essential for concept-based language instruction.
Creative multimodal and multilingual puns as and through joint actions in Korean media interviews
Authors: Kim Mary Shin
Published: October 2022

This study examines how participants in Korean media talk, specifically talk show interviews, interactively construct puns as and through joint actions. Going beyond puns as humorous wordplay, the study illustrates their interactional and pragmatic functions. A close examination of the sequential positions and interactional contexts of puns in 16 different interviews shows that they recurrently emerge when participants are placed, socially or interactionally, in delicate or difficult situations. Through puns, the participants not only recontextualise the local meaning of a particular target word, but also globally transform the focus and frame of the troublesome ongoing interaction, as well as managing their identities and roles in the interaction. The analysis shows that the participants creatively design puns based on Korean words as well as utilising English words, formulating multilingual puns. The study also demonstrates that puns are often accompanied, triggered or entirely performed by nonlinguistic devices (e.g. body movements, gestures, facial expressions). These multimodal resources play a key role in formulating creative puns, in understanding and responding to puns, and in diverting the trajectory of ongoing interaction.
Fanning out from the Fanfare
Authors: Yorgason Brent , Lyon Jeff
Published: October 2022

In 1937, Max Steiner created a fanfare for Warner Bros. to accompany the appearance of the WB shield at the beginning of each film. The fanfare made its first appearance in Tovarich, using bits and pieces from the opening themes of A Star is Born and First Lady. The C major setting of the fanfare in Gold is Where You Find It (1938) became the “canonical” version to which Steiner most frequently referred. From 1937 to 1951 it was used by Steiner and other Warner Bros. composers to open nearly every film. After 1951, Steiner began using the fanfare much less frequently, with its final appearance occurring in Battle Cry (1955).

The new phase Ba5In2Al2Zr0.9Nb0.1O13.05 with hexagonal perovskite structure was obtained. The substitution of Zr4+ by smaller Nb5+ was accompanied by the incorporation of the oxygen interstitials and did not lead to a significant change in the lattice parameters. It was established that the investigated sample was capable for water incorporation from the gas phase, the hydration degree value was 0.24 mol H2O. IR-spectroscopy analysis defined the presence of OH−-groups with different thermal stability, which participate in different hydrogen bonds. The new phase Ba5In2Al2Zr0.9Nb0.1O13.05 demonstrates the predominant protonic conductivity at pH2O = 2·10−2 atm and Т600 °C.
Local structure and ionic transport in acceptor-doped layered perovskite BaLa2In2O7
Authors: Tarasova Nataliia A.
Published: October 2022

Materials with perovskite or perovskite-related structure have many applications because of theirs different physical and chemical properties. These applications are extremely diverse and cover different fields including hydrogen energy. Layered perovskites with Ruddlesden-Popper structure constitute a novel class of ionic conductors. In this paper, the effect of acceptor doping on the local structure and its relationship with transport properties were shown for layered perovskites based on BaLa2In2O7 for the first time. The geometric factor (the increase in the unit cell volume due to the increase in the ionic radii of cations) plays major role in the area of small dopant concentration (x  0.15). The concentration factor (the increase in the oxygen vacancy concentration) is more significant in the area of big dopant concentration (x  0.15). The acceptor doping is a promising way of improving the oxygen-ionic conductivity of layered perovskite BaLa2In2O7.

Authors: Jiménez Rendón Constanza , Herrera Cano Gloria Stella
Published: October 2022

La problemática de violencia contra la mujer en Colombia se refleja mediante diferentes modalidades, independientemente de la esfera social, edad u otra característica. Sus repercusiones generan afectación psicológica y lesiones físicas en quienes la padecen directa o indirectamente. El objetivo de la presente investigación es el diseño de un instrumento con base en el modelo ecológico que permite analizar diferentes fenómenos que se manifiestan en la violencia contra la mujer en la pareja.La metodología implementada es de carácter descriptivo exploratorio en que se realiza una revisión sistemática de literatura y de informes periciales practicados a mujeres víctimas de violencia de pareja atendidas por el servicio de Psicología Forense del Instituto de Medicina Legal y Ciencias Forenses. Como discusión, se plantea que en los diferentes instrumentos diseñados para medir la violencia contra la pareja no se contempla la exploración de los factores de riesgo que mantienen la violencia hacia la mujer víctima por parte de su pareja o expareja. Se llega a conclusiones al medir los factores de riesgo que se presentan en la mujer inmersa dentro de un contexto de violencia por parte de su pareja, que se ha perpetuado o en el que se ha mantenido, lo que resulta útil en las evaluaciones por psicología forense o en estudios realizados por el área de clínica forense del instituto.
Excess Savings during the COVID-19 Pandemic

Published: October 2022

Over the pandemic, historic levels of government transfers boosted household income while household spending was severely curtailed by social distancing. This led the personal saving rate to soar (Figure 1), and we estimate that U.S. households accumulated about $2.3 trillion in savings in 2020 and through the summer of 2021, above and beyond what they would have saved if income and spending components had grown at recent, pre-pandemic trends.
Bir Budist Ahlak Klasiği: Aryaşura’nın Catakamala’sı
Authors: GÜL Ali
Published: October 2022

Dinî geleneklerin en önemli yönlerinden biri ahlaki yapılarıdır. Bütün dinler müntesiplerine ahlaklı yaşamayı salık verir ve bu anlamda birtakım prensipler ortaya koyar. Ahlaki prensipler dinlerin kutsal metinleri içinde önemli bir yer tutar. Öte yandan kutsal metinler dışında üretilen dinî literatürde ahlaki öğretileri esas alan metinlere çokça rastlanır. Bu metinler çeşitli edebî türleri kullanabilir. Budist gelenek söz konusu olduğunda Câtaka adı verilen öyküler, bu açıdan önemli bir edebî türü oluşturur. Buda’nın geçmiş yaşam anlatıları olarak tanımlanabilecek Câtakalar, onun bir bodhisattva yani Buda olma yolunda bir namzet iken sergilediği erdemleri konu edinir. Budist gelenekte yüzlerce Câtakadan söz edilir. Pali Kanon’un Câtaka kitabı bunların 547’sini içerir. Budist literatürde ilhamını Câtaka öykülerinden alan derlemeler de vardır. Aryaşura’nın (MS 4. yüzyıl?) kaleme aldığı ve otuz dört Câtaka öyküsünü barındıran Câtakamâlâ, bu derlemelerin en bilinenidir. Elinizdeki makale, bir taraftan Câtakamâlâ’yı tanıtmaya ve Câtakamâlâ’nın Budist ahlak geleneğini yansıtmadaki katkısını değerlendirmeye çalışırken diğer taraftan eserin içerdiği öyküler çerçevesinde Budizm’in kimi ahlaki esaslarını ortaya koymaya gayret edecektir

Published: October 2022

In this study, the evaluation of aluminium dross from secondary aluminium production in calcium aluminate cement was investigated. Salt compounds were removed significantly from the secondary aluminium dross by washing. Mixtures of washed dross and quicklime were prepared to obtain a cement additive by considering the standard cement with low alumina and they were sintered at 1250 °C for 5 h. The phases of mayenite, monocalcium aluminate, grossite, gehlenite, larnite, periclase and spinel were detected in the sintered samples using an X-ray diffraction analysis. Tests of the normal consistency, setting time and compressive strength were carried out at replacement levels of (2.5, 5, 7.5, 10 and 12.5) w/% of the cement additive to determine the physical properties of the cement paste/mortar. Increasing the level of the cement additive in the commercial calcium aluminate cement (ISIDAC 40) accelerated the setting time of the mortar and decreased workability.

Published: October 2022

On a Gleeble-3800 simulator, isothermal hot compression tests of an as-cast N06625 nickel-based alloy were conducted in a wide range of temperatures (950–1200 °C) and strain rates (0.1–50 s–1). Considering the influence of friction and adiabatic heating in the test, the flow curves were corrected. A modified Johnson-Cook, strain-compensated Arrhenius-type and modified Hensel-Spittel constitutive models were established based on the corrected flow curves. In a hot compression test, the flow stress is mainly affected by the coupling of the temperature, strain rate and strain, so the consideration of the coupling effect greatly affects the accuracy of the constitutive model. Moreover, different materials have different sensitivities to the three conditions. Therefore, the improved model in this paper can improve its universality and accuracy after adding relevant parts to it. The models were compared using the correlation coefficient (R) and average absolute relative error (AARE) to determine their accuracy in predicting the deformation behavior of the above alloy. According to our findings, the strain-compensated Arrhenius-type model provided the greatest forecast accuracy over the whole temperature and strain rate range. Under a certain temperature and strain rate, the modified Johnson-Cook model provided the best prediction accuracy.

Authors: Lin Feng , Duan Jingying , Lu Qiuxia , Li Xibing
Published: October 2022

An electronic product shell is prone to uneven shrinkage, warpage and sink marks, resulting in a large number of unqualified products and increased costs. Therefore, volumetric shrinkage, warpage deformation and sink mark index are selected as optimization goals. Based on the orthogonal test and entropy weight method, a multi-objective optimization was transformed into a comprehensive evaluation optimization. A BP neural network combined with a particle swarm optimization algorithm was used to obtain the optimal combination of process parameters, simulated by Moldflow to reduce volumetric shrinkage to 3.46 %, warpage deformation to 2.538 mm, and the sink mark index to 1.87 % so as to improve the injection molding quality of the plastic parts and meet the requirements of qualified parts. The combination of the BP neural network and particle swarm optimization algorithm can prevent the defects such as large shrinkage, warpage and sink marks

Authors: Işık Tuğçe , Sağın Elif Uğurlu
Published: October 2022

In this study, Byzantine-period lime mortars and plasters used in the Anaia Church in Kuşadası- Aydın were examined in order to determine their characteristics and investigate the continuity of the lime mortar technology through centuries in the Anaia Church. The results will also contribute to future conservation studies at the site. Basic physical properties, raw-material compositions and hydraulic properties of lime mortars and plasters; mineralogical and chemical compositions, microstructural properties of binders, aggregates and limes; and pozzolanic activities of aggregates were determined using RILEM test methods, XRD, SEM-EDX and TGA. Mortar samples were comprised of natural aggregates whereas lime plasters were made of brick aggregates. Analyses revealed that plasters were slightly less dense and more porous than mortars due to the porous structure of the brick aggregates. All mortars and plasters were hydraulic due to the use of highly reactive pozzolanic aggregates. The basic physical properties, raw-material compositions, mineralogical and chemical compositions of mortars and plasters were found to be similar throughout the construction periods spread over different centuries. These similarities revealed the conscious knowledge of the lime mortar technology during the Byzantine period in western Anatolia.

Published: October 2022

This study aims to examine the effect of overconfidence behaviours of the managers of the companies whose stocks are traded in Borsa Istanbul on the firm value. In the study, a model was created for Tobin q (Model 1), stock market value (Model 2) and enterprise value (Model 3). As a result of the study, a negative relationship was determined between the change in firm value and the overconfidence variable. According to this result, if the managers performing mergers and acquisitions are overconfident, the incorrect decision may be made while determining the firm value. This leads to a decrease in the wealth of the shareholders. In this respect, managers' overconfidence should also be considered while performing mergers and acquisitions in firms.
