The Effect of Composition of Synthesis Gas on the Parameters of Supercharged Combustion Engine
Authors: Chríbik Andrej , Luknár Lukáš , Hošták Peter , Jančo Roland 
Published: November 2024

Abstract
Synthesis gases produced from municipal waste or plastic waste pose a great alternative source of energy, as they are not only reducing dependency on the fossil fuels, but also diversify energy sector and reduce the amount of a landfilled waste. This is directly related to the recent initiatives and legislation related to the greening of transport. The presented contribution focuses on the influence of six selected synthesis gases on the internal parameters of an internal combustion engine intended for cogeneration. The investigated gases fall into the category of medium-energy gases (8 – 14 MJ.kg−1). The experimental measurements have shown that mainly the proportion of hydrogen in the mixture has an effect on shortening the burning time and also on the maximum rate of pressure increase. A higher proportion of CO and H2 increased the maximum combustion pressure with slightly reduced power. The concentration of CH4 directly affected the volumetric value of the heating value of the mixture with a subsequent direct effect on the IMEP or engine torque. The engine operating at full load at speed of 1500 min−1, when running on the selected mixtures in comparison with the operation on natural gas, decreased its engine torque in the range between 13 and 20% and increased its hourly fuel consumption from 2.31 kg.h−1 for natural gas to the span of 7.90 - 12.30 kg.h−1 for measured gases. During the measurement of the control characteristic all investigated synthesis gases have developed an abnormal (detonation) combustion near the optimum pre-ignition angle.

Abstract
The presented studies made it possible to clarify the calculation model of the diesel engine clutch with packages of sleeve springs. The stressed state of the spring packets is considered, while it is proposed to place the point of application of the radial force, which bends the spring package, in the zone of its greatest flexibility. Calculations performed according to the obtained expressions showed a coincidence with the results of experimental studies by other authors within 4% and with simulations conducted using automated design systems.

Abstract
This study aims to evaluate the durability of as-cast Ti-6Al-7Nb in femoral stem application using fatigue analysis. As-cast Ti-6Al-7Nb rod specimens were tested experimentally with load range of 120%, 100%, 90%, 80%, 70%, 50%, 30%, and 20% relative to the yield strength. The fatigue limit was identified on a range of 141 - 211 MPa, represented by two run-out specimens running until high fatigue cycle (HFC) of 107 without failure. ProFatigue contributed to expose the estimation of the expected failure cycle on fatigue limit stress of as- cast Ti-6Al-7Nb based on Weibull modelling. It was predicted by probability failure (Pfail) of 50%. The failure cycles were revealed at 2.144 x 107 and 2.823 x 109 cycles on amplitude stress of 211 and 141 MPa, respectively. The reliability of the designed femoral stem for Indonesian people has been analyzed under ISO 7206 configuration through finite element analysis by adopting the material properties of as-cast Ti-6Al-7Nb. The static linear analysis demonstrated the maximum stress concentration of 136 MPa occurring over the medial region of the femoral stem, showing lower stress levels compared to the fatigue limit of as-cast Ti-6Al-7Nb. Furthermore, the lifetime analysis computed that the design could withstand cyclic loading until 2.51 x 109 cycles with fatigue safety factor and damage factor in 1.763 and 0.398, respectively. Results concluded that the investment casting is evident to become an alternative manufacturing method of femoral stem made of Ti-6Al-7Nb.
Mechanisms of Bolt Preload Relaxation Arising from In-Plane Loads and Bolt Bending
Authors: Welch Michael 
Published: November 2024

Abstract
Classical analysis methods have shown that flexural, in-plane, deflections due to shear strain in the flange pack of preloaded bolted joints produce bending moments and tensile loads on bolts within the joint. These bending moments and tensile loads are most noticeable in joints that are required to support large in-plane loads and torsional moments. The shear loads on the bolt associated with the flexural deflections can result in the bolt head, or nut, slipping relative to the flanges. This slippage will in turn result in mechanical loosening of the joint. The bending moments associated shear loads and tensile loads produced by the combination of both out-of-plane and in-plane external loads and torsional moments are in addition to the bolt preload. These additional loads, combined with a high initial bolt preload, can cause yielding of the bolt, which can also result in relaxation of the initial preload. This article reviews earlier work in determining the tensile bolt stresses induced in preloaded bolts by the external loads and presents methods of calculating the amount of preload relaxation that could occur from each mechanism discussed.
Pricing Asian Options in Uncertain Stochastic Markets With Jumps
Authors: Chirima Justin , Matenda Frank Ranganai , Sibanda Mabutho 
Published: November 2024

Objective: In practice, the securities industry is characterized by processes exhibiting both randomness and Liu's uncertainty, sometimes called uncertainty. This study proposes Asian option pricing models in uncertain random markets with jumps.

Theoretical Framework: This research is based on the concepts of probability, uncertainty, and uncertain stochastic differential equations (USDEs) with jumps.

Method: We use an uncertain random stock model with a jump to derive option pricing models in uncertain random markets with jumps. Using USDEs with jumps is a new paradigm in modeling dynamical systems. The solution to the extraordinary type of an uncertain stochastic differential equation (USDE) with jumps examined in this article combines a jump component and the geometric Itô-Liu process. It plays a pivotal role in deriving Asian option pricing formulae under study.

Results and Discussion: This study shows that objective randomness and subjective uncertainty are essential in pricing Asian options.

Research Implications: The proposed procedures in this branch of knowledge can be used to price Asian options.

Originality/Value: This study contributes to the literature by adequately capturing the effects of indeterminacy in pricing Asian options.

Authors: Kazaryan Knarik , Hunanyan Naira , Danielyan Margarita , Mkrtchyan Arus , Chibukchyan Roza , Trofimova Yulia , Piliposyan Tatevik 
Published: November 2024

Objectives:
The effect of oxytocin on spontaneous electrical activities of rhythmogenic areas in the right and left uterine horns (ovarian and cervical areas) was investigated in non-pregnant rats.

Materials and Methods:
Comparative analysis of the main characteristics of spontaneous activity (amplitude of action potentials [A]; mean rise- rate [V]; rise - time [T/2]; half-width [t] of spikes; total duration of bursts in 1 minute [D], and spike generation frequency [F]) was conducted. Morphofunctional properties of the rat uterine horns were studied by using a histochemical method, which had been developed based on the Homori method.

Results:
The left ovarian horn area is characterized by parameters significantly exceeding those of the other three areas, which are identical to each other. Administration of oxytocin, as a factor promoting increased excitability of the myometrium, led to significant enhancement of rhythmogenesis in the right ovarian horn area. Morphohistochemical results revealed an increase in enzymatic activity of the myometrium under the influence of oxytocin, with the right ovarian horn area showing the greatest changes.

Conclusion:
Since oxytocin plays a key role in stimulating activity and enhancing the myometrial contractions of the right fallopian tube, the possibility of additional reserve capabilities in the regulation of the integrative function of the reproductive organs cannot be excluded from the study.

The purpose of the article is to trace the global trends of ecocriticism, to present progress in Ukrainian literary studies in the field of ecocritical studies. The methodology of the publication is based on general scientific methods of analysis and synthesis, and the tools of ecocriticism as aninterdisciplinary approach were also used.
The result of the study is a presentation of the achievements of ecocriticism at various stages, starting from the emergence of new trends in the methodology in the 1970s to the modern stage. It is noted the role of researches of such scientists as: Cheryll Glotfelty, Michelle Belaev, Harold Fromm, Christopher Cocinos, Derek Gladwin and other. The periodization of ecocriticism is outlined (three waves of ecocriticism) (The Future of Environmental Criticism: Environmental Crisis andLiterary Imagination, 2005).
It is noted a tendency to interpret ecocriticism as a science that creates a network of interdisciplinary connections in a number of studies of the early 2000s. (Terrel Dixon (2002). City Wilds: Essays and Stories about Urban Nature; John Tallmadge (2004). The Cincinnati Arch: Learning from Nature in the City).
Considerations about the specifics of the third wave of ecocriticism are considered (Marshall, 2005; Slovic, 2010). It is noted that over the thirty years of ecocriticism asa separate discipline, a qualitative transition has occurred from ecocriticism characterized by ecofetishism, romanticism, discursive feminism, to ecocosmopolitanism, ecocultural studies, ecofeminism, "green" gender theories, etc. The opinion about the new wave of ecocriticism - planetary is singled out(S. Slovic, 2012). The achievements of ecocriticism in Ukrainian literary studies are consideredStudies dedicated to the research of foreign literature are singled out.
It is noted that ecocritical trends can also be traced in various types of fine art. Attention to ecocritical studies is evidenced by such humanities as pedagogy, philosophy, journalism, cultural studies, and others. The conclusions emphasize that the systematized material presents the relevance of ecocritical studies.

Published: November 2024

The uncertainty of transition to school for refugee children can be alleviated through early childhood programs that cater to children, families, and communities. This paper reports findings from a Home Interaction Program for Parents and Youngsters (HIPPY), where free, home-based early childhood learning occurs during the critical period of the child’s transition to full-time school. The project aimed to support Ezidi parent’s capacity to prepare their children for Australian school contexts and to build a sense of belonging among Ezidi children in their new community in regional New South Wales (NSW), Australia. This qualitative study was based on a case study informed by Vygotsky’s sociocultural theory and Bronfenbrenner’s socio-ecological theory. Data were analyzed for themes using NVivo software. Findings indicated the HIPPY program supported Ezidi children's transition to school. Challenges such as parents’ English language proficiency and limited knowledge about the program resulted in the parents not being fully involved.

Дифференциация благосостояния населения в регионах России: сырьевой фактор и возможности налогового регулирования
Authors: Пугачев А.А. , Чистякова А.А. 
Published: November 2024

В статье исследуется влияние на неравенство граждан распределения добавленной стоимости сырьевого сектора. При исключении из ВРП валовой добавленной стоимости добычи полезных ископаемых размах вариации по соотношению душевого ВРП с границей бедности в 2021 г. сократился с 35,33 до 10,52 разa. Обоснована необходимость двуступенчатого воздействия на межрегиональное и внутрирегиональное неравенство – с применением селективного подхода и с учетом территориальной поляризации благосостояния. В рамках применения налогового инструментария важно исключить ситуацию, когда меры в области снижения неравенства граждан приводят к нарастанию неравенства регионов. Решением может быть закрепление дополнительных налоговых доходов от сглаживания «шпиля» неравенства граждан за федеральным центром с последующим перераспределением в рамках межбюджетного выравнивания.

Published: November 2024

Este artículo propone una reflexión transversal desde las dimensiones técnica, artística y epistémica con el objetivo de recuperar y producir conocimientos acerca de mezclas de pinturas con tierra, experimentar un proceso creativo colaborativo desde una dialéctica visual durante la ejecución del mural, e indagar desde ese proceso. Las metodologías empleadas son: investigación-acción participativa, investigación-creación, performance y ensayos de tierra. Se exploraron mezclas con diferentes arcillas, aditivos y proporciones resultando 3:2 con baba de penca, 1:1 con un 15% de cola vinílica. La paleta de color resulta de cada combinación de tipo de suelo con cada aditivo. Las huellas visuales permiten un diálogo entre las intervenciones de manera asincrónica, desde los espectros del que pintó y dejó un rastro visual. El proceso de taller y ejecución del mural se convierten en espacios de encuentro, de presencia/ausencia, transmitiendo y produciendo conocimientos a través de las materialidades visuales.

Introducción: El estudio tuvo como objetivo principal analizar la probabilidad y predicción para la temperatura ambiental y el suelo en la zona costera de Manabí en Ecuador. Metodología: La metodología hace uso de series de tiempo Box Jenkins ARIMA y de comparación de medias. Los datos se midieron a las 07:00 am, 12:00 pm y 18:00pm, iniciando en enero de 2015 hasta diciembre del 2020. Los datos se analizaron y procesaron con la ayuda de la inteligencia artificial incorporada al software RStudio. Resultados: Los resultados, evidencian que la temperatura del suelo está correlacionada con la temperatura ambiental. Discusión: Las pruebas de bondades de ajuste para los coeficientes y supuestos validaron el modelo ARIMA observado y esperado. Además, los criterios AIC y BIC se utilizaron para escoger el mejor modelo predictivo. Conclusiones: En conclusión, la inteligencia artificial identificó que la predicción de las temperaturas ambiental y del suelo son simuladas adecuadamente a través de un modelo ARIMA(0,1,1)(0,1,1)[12], con componentes de tendencia y estacionalidad; afirmando un modelo de series de tiempo no estacionario. Se llega a determinar que, la temperatura tiene una pequeña variabilidad por cada periodo de tiempo, pero en aumento, y en lo posterior probablemente este factor climático se convierta en un determinante del calentamiento global.
