Wettability and Mechanical Properties of Red Mud–Al2O3 Composites
Authors: Chen Yongliang , Li Anmin , Jiang Shiwei
Published: February 2024

In 2023, the global production of new red mud is expected to reach nearly 200 million tons, but less than 10% of it is currently being utilized in an environmentally friendly manner. To reduce the sintering temperature of alumina ceramics, a sintering aid method is used, as high-purity alumina ceramics require a solid-phase sintering temperature of over 1700 °C. The metal oxides present in red mud are necessary components for high-performance composite alumina ceramics. Composites were obtained by mixing and sintering red mud and Al2O3. This study focused on the mechanical properties and wettability of these composites. The results indicated that the 10% red mud–Al2O3 composite exhibited the highest hardness (20.12 GPa) and flexural strength (346 MPa). This is attributed to the formation of a mineral phase dominated by CaAl12O19, generated by the red mud during the sintering process, which filled the pores and reduced porosity. The surface energy of the red mud–Al2O3 composite was the highest at room temperature and high temperature, reaching 49.60 mJ·m−2 and 1164.7 mJ·m−2, respectively, indicating that it has better stability at both room and high temperatures. This study provides an important fundamental basis for the application of red mud–alumina composites to replace alumina-based composites in the field of construction materials, molten metal filters, ceramic cleavers, etc.

Published: February 2024

The formulation of the entropic statistical theory and the related neo-Hookean model has been a major advance in the modeling of rubber-like materials, but the failure to explain some experimental observations such as the slope in Mooney plots resulted in hundreds of micromechanical and phenomenological models. The origin of the difficulties, the reason for the apparent need for the second invariant, and the reason for the relative success of models based on the Valanis–Landel decomposition have been recently explained. From that insight, a new micro–macro chain stretch connection using the stretch tensor (instead of the right Cauchy–Green deformation tensor) has been proposed and supported both theoretically and from experimental data. A simple three-parameter model using this connection has been suggested. The purpose of this work is to provide further insight into the model, to provide an analytical expression for the Gaussian contribution, and to provide a simple procedure to obtain the parameters from a tensile test using the Mooney space or the Mooney–Rivlin constants. From different papers, a wide variety of experimental tests on different materials and loading conditions have been selected to demonstrate that the simple model calibrated only from a tensile test provides accurate predictions for a wide variety of elastomers under different deformation levels and multiaxial patterns.
Design and Study of Machine Tools for the Fly-Cutting of Ceramic-Copper Substrates
Authors: Zhang Chupeng , Sun Jiazheng , Zhou Jia , Chen Xiao
Published: February 2024

Ceramic-copper substrates, as high-power, load-bearing components, are widely used in new energy vehicles, electric locomotives, high-energy lasers, integrated circuits, and other fields. The service length will depend on the substrate’s copper-coated surface quality, which frequently achieved by utilising an abrasive strip polishing procedure on the substrate’s copper-coated surface. Precision diamond fly-cutting processing machine tools were made because of the low processing accuracy and inability to match the production line’s efficiency. An analysis of the fly-cutting machining principle and the structural makeup of the ceramic-copper substrate is the first step in creating a roughness prediction model based on a tool tip trajectory. This model demonstrates that a shift in the tool tip trajectory due to spindle runout error directly impacts the machined surface’s roughness. The device’s structural optimisation design is derived from the above analyses and implemented using finite element software. Modal and harmonic response analysis validated the machine’s gantry symmetrical structural layout, a parametric variable optimisation design optimised the machine tool’s overall dimensions, and simulation validated the fly-cutterring’s constituent parts. Enhancing the machine tool’s stability and motion accuracy requires using the LK-G5000 laser sensor to measure the guideway’s straightness. The result verified the machine tool’s design index, with the Z- and Y-axes’ straightness being better than 2.42 μm/800 mm and 2.32 μm/200 mm, respectively. Ultimately, the device’s machining accuracy was confirmed. Experiments with flying-cut machining on a 190 × 140 mm ceramic-copper substrate yielded a roughness of Sa9.058 nm. According to the experimental results, the developed machine tool can fulfil the design specifications.

Published: February 2024

One therapeutical alternative in the treatment of functional disorders is the use of printed oral splints. The mechanical properties of these materials are highly essential to their clinical effectiveness, and their performance may vary depending on factors such as cleaning, post-polymerization, or their orientation during construction. The objective of this in vitro investigation is to evaluate the effectiveness of the selected materials in terms of their biaxial flexural strength in relation to the criteria listed above. Splint materials were used in the printing of 720 discs. The printing process was carried out in different orientations in relation to the building platform. Either an automatic or manual cleaning process was performed on the samples. For post-polymerization, either an LED or Xenon light was utilized. A piston-on-three-ball test was used to measure the biaxial flexural strength (BFS) of the materials after they were stored in water for either 24 h or 60 days. The homogeneity of the data was controlled by employing the Levene method, and the differences between the groups were analyzed using the ANOVA and Bonferroni methods. After being stored for twenty-four hours, the mean BFS ranged anywhere from 79 MPa to 157 MPa. Following a period of sixty hours, the BFS exhibited a substantial drop and revealed values that ranged from 72 to 127 MPa. There was no significant difference that could be identified between the materials or between the various cleaning processes. The results of post-polymerization showed that the LED light produced higher means than the Xenon light did. In terms of position, the mean values varied greatly, with 0°’s mean value being 101 MPa, 45°’s mean value being 102 MPa, and 90°’s mean value being 115 MPa. The use of a build orientation of 90° and post-polymerization with LED light resulted in significantly increased biaxial flexural strength. According to this study, this design should be implemented in order to ensure that splint materials have the highest possible strength.

Published: February 2024

The spring-in phenomenon of the composite parts can affect the assembly process. This study aims to predict the spring-in phenomenon of a carbon fiber reinforced plastic (CFRP) part. Here, we predict the spring-in of the CFRP part using a coupled analysis of the forming and cooling processes during the stamping process. First, a simulation of the entire forming process, such as the transfer of the composite laminate, gravity analysis, and forming was performed to obtain the temperature distribution of the CFRP part. Subsequently, a finite-element (FE) simulation of the cooling process was conducted to predict the spring-in phenomenon of the shaped CFRP part using the temperature data obtained in the forming simulation. Finally, a CFRP part was manufactured and compared with the results of the FE simulation.
Optimal Corrective Maintenance Policies via an Availability-Cost Hybrid Factor for Software Aging Systems
Authors: Huo Huixia
Published: February 2024

Availability is an important index for the evaluation of the performance of software aging systems. Although the corrective maintenance increases the system availability, the associated cost may be very high; therefore, the balancing of availability and cost during the corrective maintenance phase is a critical issue. This paper investigates optimal corrective maintenance policies via an availability-cost hybrid factor for software aging systems. The system is described by a group of coupled differential equations, where the multiplier effect of the repair rate on a system variable is bilinear term. Our aim is to drive an optimal repair rate that ensures a balance between the maximal system availability and the minimal repair cost. In a finite time interval [0,T], we rigorously discuss the state space of the system and prove the existence of the optimal repair rate, and then derive the first-order necessary optimality conditions by applying a variational inequality with the adjoint variables.
Enhancing Deep Learning and Computer Image Analysis in Petrography through Artificial Self-Awareness Mechanisms
Authors: Dell’Aversana Paolo
Published: February 2024

In this paper, we discuss the implementation of artificial self-awareness mechanisms and self-reflection abilities in deep neural networks. While the current limitations of research prevent achieving cognitive capabilities on par with natural biological entities, the incorporation of basic self-awareness and self-reflection mechanisms in deep learning architectures offers substantial advantages in tackling specific problems across various scientific fields, including geosciences. In the first section, we outline the foundational architecture of our deep learning approach termed Self-Aware Learning (SAL). The subsequent part of the paper highlights the practical benefits of this machine learning methodology through synthetic tests and applications addressed to automatic classification and image analysis of real petrological data sets. We show how Self-Aware Learning allows enhanced accuracy, reduced overfitting problems, and improved performances compared to other existing methods.

Published: February 2024

Essential oils are well known for their biological properties, making them useful for the treatment of various diseases. However, because of their poor stability and high volatility, their potential cannot be fully exploited. The use of nanoformulations to deliver essential oils can solve these critical issues and amplify their biological activities. We characterized an essential oil from Satureja thymbra via GC–MS and HPLC–DAD to provide qualitative and quantitative data. The essential oil was formulated in phospholipid vesicles which were characterized for size, surface charge, and storage stability. The entrapment efficiency was evaluated as the quantification of the major monoterpenoid phenols via HPLC–DAD. The morphological characterization of the vesicles was carried out via cryo-TEM and SAXS analyses. The essential oil’s antioxidant potential was assayed via two colorimetric tests (DPPH• and FRAP) and its cytocompatibility was evaluated in HaCaT skin cell cultures. The results showed that the nanoformulations developed for the loading of S. thymbra essential oil were below 100 nm in size, predominantly unilamellar, stable in storage, and had high entrapment efficiencies. The vesicles also displayed antioxidant properties and high cytocompatibility. These promising findings pave the way for further investigation of the therapeutic potential of S. thymbra nanoformulations upon skin application.
Probing Non-Covalent Interactions through Molecular Balances: A REG-IQA Study
Authors: Falcioni Fabio , Bennett Sophie , Stroer-Jarvis Pallas , Popelier Paul L. A.
Published: February 2024

The interaction energies of two series of molecular balances (1-X with X = H, Me, OMe, NMe2 and 2-Y with Y = H, CN, NO2, OMe, NMe2) designed to probe carbonyl…carbonyl interactions were analysed at the B3LYP/6-311++G(d,p)-D3 level of theory using the energy partitioning method of Interacting Quantum Atoms/Fragments (IQA/IQF). The partitioned energies are analysed by the Relative Energy Gradient (REG) method, which calculates the correlation between these energies and the total energy of a system, thereby explaining the role atoms have in the energetic behaviour of the total system. The traditional “back-of-the-envelope” open and closed conformations of molecular balances do not correspond to those of the lowest energy. Hence, more care needs to be taken when considering which geometries to use for comparison with the experiment. The REG-IQA method shows that the 1-H and 1-OMe balances behave differently to the 1-Me and 1-NMe2 balances because the latter show more prominent electrostatics between carbonyl groups and undergoes a larger dihedral rotation due to the bulkiness of the functional groups. For the 2-Y balance, REG-IQA shows the same behaviour across the series as the 1-H and 1-OMe balances. From an atomistic point of view, the formation of the closed conformer is favoured by polarisation and charge-transfer effects on the amide bond across all balances and is counterbalanced by a de-pyramidalisation of the amide nitrogen. Moreover, focusing on the oxygen of the amide carbonyl and the α-carbon of the remaining carbonyl group, electrostatics have a major role in the formation of the closed conformer, which goes against the well-known n-π* interaction orbital overlap concept. However, REG-IQF shows that exchange–correlation energies overtake electrostatics for all the 2-Y balances when working with fragments around the carbonyl groups, while they act on par with electrostatics for the 1-OMe and 1-NMe2. REG-IQF also shows that exchange–correlation energies in the 2-Y balance are correlated to the inductive electron-donating and -withdrawing trends on aromatic groups. We demonstrate that methods such as REG-IQA/IQF can help with the fine-tuning of molecular balances prior to the experiment and that the energies that govern the probed interactions are highly dependent on the atoms and functional groups involved.

Theurgy, Paredroi, and Embodied Power in Neoplatonism and Late Antique Celestial Hierarchies
Authors: Pejovic Katarina
Published: February 2024

This article will place the rituals of the Greek Magical Papyri (PGM) for the acquisition of a supernatural assistant (paredros) into conversation with broader late antique debates surrounding the place of daimones within the celestial hierarchy. In considering the writings of Plotinus, Plutarch, Porphyry, and Iamblichus, it will survey points of contention surrounding questions of appropriate and inappropriate displays of ritual power, as facilitated by intermediary spirits who act as intercessors between humanity and the divine. Through analyzing the metaphysical underpinnings of the nature of the paredros, as variously articulated within the rituals for their conjuration within the Greek Magical Papyri, it will contextualize the aims of the ritualist against the backdrop of Iamblichus’ theurgy in pursuit of mastery of—and intimate, transcendent communion with—the fundamental numinous nature of the world. In doing so, this article argues that Iamblichus’ theurgy and the paredros rituals of the PGM ultimately grasp towards similar soteriological goals using different ritual methodologies; both seeking to elevate the incarnated body of the ritualist into a higher level of spiritual attainment through direct confrontation with the powers of nature.
Analysis and Compensation of Phase Current Measuring Error Caused by Sensing Resistor in PMSM Application
Authors: Cheng Xin , Hu Jinfeng , Yu Ye , Zhou Rougang , Yu Qiang
Published: February 2024

Field Oriented Control (FOC) effectively realizes independent control of flux linkage and torque, and is widely used in application of Permanent Magnet Synchronous Motor (PMSM). However, it is necessary to detect the phase current information of the motor to realize the current closed-loop control. The phase current detection method based on a sampling resistor will cause a measurement error due to the influence of parasitic parameters of the sampling resistor, which will lead to the decrease in PMSM control performance. This paper reveals the formation mechanism of the current sampling error caused by parasitic inductance and capacitance of the sampling resistor, and further confirms that the above error will lead to the fluctuation of the electromagnetic torque output by simulation. Moreover, we propose an approach for online observation and compensation of the current sampling error based on PI-type observer to suppresses the torque pulsation of PMSM. The phase current sampling error is estimated by the proportional and integral (PI) observer, and the deviation value of current sampling is obtained by low-pass filter (LPF). The above deviation value is further injected into the phase current close-loop for error compensation. The PI observer continues to work to keep the current sampling error close to zero. The simulation platform of Matlab/Simulink (Version: R2021b) is established to verify the effectiveness of online error observation and compensation. Further experiments also prove that the proposed method can effectively improve the torque fluctuation of the PMSM and enhance its control accuracy performance of rotation speed.

A Neural Network Computational Spectrometer Trained by a Small Dataset with High-Correlation Optical Filters
Authors: Liao Haojie , Yang Lin , Zheng Yuanhao , Wang Yansong
Published: February 2024

A computational spectrometer is a novel form of spectrometer powerful for portable in situ applications. In the encoding part of the computational spectrometer, filters with highly non-correlated properties are requisite for compressed sensing, which poses severe challenges for optical design and fabrication. In the reconstruction part of the computational spectrometer, conventional iterative reconstruction algorithms are featured with limited efficiency and accuracy, which hinders their application for real-time in situ measurements. This study proposes a neural network computational spectrometer trained by a small dataset with high-correlation optical filters. We aim to change the paradigm by which the accuracy of neural network computational spectrometers depends heavily on the amount of training data and the non-correlation property of optical filters. First, we propose a presumption about a distribution law for the common large training dataset, in which a unique widespread distribution law is shown when calculating the spectrum correlation. Based on that, we extract the original dataset according to the distribution probability and form a small training dataset. Then a fully connected neural network architecture is constructed to perform the reconstruction. After that, a group of thin film filters are introduced to work as the encoding layer. Then the neural network is trained by a small dataset under high-correlation filters and applied in simulation. Finally, the experiment is carried out and the result indicates that the neural network enabled by a small training dataset has performed very well with the thin film filters. This study may provide a reference for computational spectrometers based on high-correlation optical filters.

Published: February 2024

With the advancement of engineering techniques, underground shield tunneling projects have also started incorporating emerging technologies to monitor the forces and displacements during the construction and operation phases of shield tunnels. Monitoring devices installed on the tunnel segment components generate a large amount of data. However, due to various factors, data may be missing. Hence, the completion of the incomplete data is imperative to ensure the utmost safety of the engineering project. In this research, a missing data imputation technique utilizing Random Forest (RF) is introduced. The optimal combination of the number of decision trees, maximum depth, and number of features in the RF is determined by minimizing the Mean Squared Error (MSE). Subsequently, complete soil pressure data are artificially manipulated to create incomplete datasets with missing rates of 20%, 40%, and 60%. A comparative analysis of the imputation results using three methods—median, mean, and RF—reveals that this proposed method has the smallest imputation error. As the missing rate increases, the mean squared error of the Random Forest method and the other two methods also increases, with a maximum difference of about 70%. This indicates that the random forest method is suitable for imputing monitoring data.

Published: February 2024

This paper presents the development of path-tracking control strategies for an over-actuated autonomous electric vehicle. The vehicle platform is equipped with four-wheel steering (4WS) as well as torque vectoring (TV) capabilities, which enable the control of vehicle dynamics to be enhanced. A nonlinear model predictive controller is proposed taking into account the nonlinearities in vehicle dynamics at the limits of handling as well as the crucial actuator constraints. Controllers with different actuation formulations are presented and compared to study the path-tracking performance of the vehicle with different levels of actuation. The controllers are implemented in a high-fidelity simulation environment considering scenarios of vehicle handling limits. According to the simulation results, the vehicle achieves the best overall path-tracking performance with combined 4WS and TV, which illustrates that the over-actuation topology can enhance the path-tracking performance during conditions under the limits of handling. In addition, the performance of the over-actuation controller is further assessed with different sampling times as well as prediction horizons in order to investigate the effect of such parameters on the control performance, and its capability for real-time execution. In the end, the over-actuation control strategy is implemented on a target machine for real-time validation. The control formulation proposed in this paper is proven to be compatible with different levels of actuation, and it is also demonstrated in this work that it is possible to include the particular over-actuation formulation and specific nonlinear vehicle dynamics in real-time operation, with the sampling time and prediction time providing a compromise between path-tracking performance and computational time.

Authors: Gouvernet Brice
Published: February 2024

This study addresses the critical need for French-language tools in assessing sexual satisfaction, an important aspect of global health, sexual health, and mental health. Its main aim is to validate the French version of the NSSS-SF scale (NSSS-SF Fr, Fr for French). The research was conducted in two phases. The first study involved 253 participants, predominantly female (77.75%), with a focus on examining the tool’s psychometric properties (factorial structure, internal consistency, convergent validity). The second study included 855 participants, with a similar gender distribution, aimed at further validation and analysis, studying links between NSSS-SF Fr and anxiety and depressive symptoms (assessed with GAD7 and MDI), and attachment style (ECR-RS). The NSSS-SF Fr demonstrated robust psychometric properties. Key findings included its strong correlation with sexual health indicators, anxiety, depression, and attachment styles confirming its effectiveness as a reliable tool for evaluating sexual satisfaction in French-speaking populations. Comparisons with international studies highlighted its universal applicability and cultural sensitivity. The NSSS-SF French version stands as a critical tool for future research and clinical practice, bridging a vital gap in the assessment of sexual satisfaction among French-speaking individuals.
Waste Lignocellulosic Biomass as a Source for Bioethanol Production
Authors: Rola Klemen , Gruber Sven , Goričanec Darko , Urbancl Danijela
Published: February 2024

Synthetically produced biofuels play a critical role in the energy transition away from fossil fuels. Biofuels could effectively lower greenhouse gas (GHG) emissions and contribute to better air quality. One of these biofuels is bioethanol, which could act as a gasoline replacement. For this purpose, a simulation of bioethanol production through lignocellulosic biomass fermentation, focused on distillation, was carried out in simulation software Aspen Plus. Since the possibility of absolute ethanol production through distillation is limited by the ethanol–water azeotrope, pressure swing distillation (PSD) was used to obtain fuel-grade ethanol (EtOH) with a fraction of 99.60 wt.%. The flowsheet was optimised with NQ analysis, which is a simple optimisation method for distillation columns. We found that the PSD has the potential to concentrate the EtOH to a desired value, while simultaneously removing other unwanted impurities whose presence is a consequence of pretreatment and fermentation processes.
Corruption perception and financial culture in Hungary
Authors: Zéman Zoltán , Bárczi Judit , Kálmán Botond Géza
Published: February 2024

This study focuses on the correlation between corruption and financial inclusion using statistical methods. The population studied were the people of Hungary. The organisations publishing the source indices of the study took representative samples of the population. The authors used data available from public sources on the internet for their study. They analysed time series data of two indices of corruption perception and two indices measuring financial culture and inclusion. The data from secondary sources were analysed applying statistical methods. They surveyed the correlation between corruption indices, the connection between the two financial indices and also the links of corruption and financial indices. The findings of the study prove there is a close positive correlation between the indices measuring financial inclusion. The findings of indices measuring corruption are less compatible. Corruption indices relying more on statistics and less on subjective opinions and indices of financial inclusion have also provided positive correlation. Our findings offer practical benefits: corruption sensitivity can not only improve through legal means or by increasing prosperity but also by spreading economic knowledge and providing a larger group of people with access to financial services.
Examining competences affecting financial success among micro-enterprises in the Southern Great Plain : Results of a pilot study
Authors: Kuruczleki Éva , Kazár Klára
Published: February 2024

In micro-enterprises, financial decision-making is typically concentrated in the hands of one person, therefore the competences of the leading financial decisionmaker significantly determine the financial success of the enterprise. In our pilot study, we examined the impact of three competences (financial literacy, digital and entrepreneurial competences), on financial success among micro-enterprises in the Southern Great Plain region, in a 92-item sample, using PLS path analysis. The results showed that the most important factors in financial decision-making are the behaviour and acquired practices of the decision-makers, and we proved that the combination of the three competences has a positive effect on the financial success of enterprises.

Published: February 2024

En el estudio de las relaciones exteriores argentinas, la consulta de la documentación oficial permite acercarnos a las políticas públicas que delinearon la política exterior. Considerando que la documentación de archivo es el sedimento natural de las acciones de un organismo, brinda herramientas para aproximarse al “Estado desde adentro”. Es decir, a las historias y cronologías propias de las agencias estatales, las trayectorias de los sujetos que las orientan, las prácticas y saberes en su interior, y los márgenes permeables entre esas agencias y la sociedad civil. Esta mirada destaca las políticas públicas y permite repensar la supuesta “eficacia” estatal.

Este artículo propone que una aproximación a la historia del Archivo de la Cancillería Argentina puede contribuir al trabajo historiográfico. Para ello, presenta agrupaciones documentales sobre la relación con Alemania durante la Segunda Guerra Mundial, haciendo hincapié en las áreas que produjeron la documentación, su organización, cronología e historia archivística.
Las relaciones de Argentina con los dos estados alemanes en el marco del conflicto de Malvinas y el Atlántico Sur (1982-1989)
Authors: Lafuente Víctor Manuel
Published: February 2024

La guerra de Malvinas marcó un giro en la política exterior argentina, que afectó sus relaciones tradicionales con las potencias del Norte Global. Muchos de esos Estados mantenían relaciones de raigambre cultural y económica con Argentina, como es el caso de Alemania que, en el marco de la Guerra Fría, se encontraba dividida en dos estados, la RFA y la RDA. El artículo busca definir la influencia del conflicto del Atlántico Sur en las relaciones  de Argentina con ambos estados, teniendo en cuenta las reacciones durante las hostilidades, entre abril y junio de 1982, y la etapa posterior hasta la reunificación alemana en 1990 y la reanudación de las relaciones diplomáticas entre Argentina y el Reino Unido.
Germanidad y cultura de guerra: representaciones de la revista Germania sobre el militarismo alemán en Argentina durante la Gran Guerra
Authors: Ingrassia Marcelo Alejandro
Published: February 2024

El presente artículo forma parte de un proyecto más amplio orientado a investigar las representaciones de la comunidad germanohablante en el contexto de la Gran Guerra expresadas en la revista Germania. La revista se publicó desde junio de 1915 hasta mayo de 1916; coyuntura en la cual –si bien la guerra se había paralizado en el frente occidental– la propaganda aliadófila y germanófila comenzaba a recuperar protagonismo en la prensa local frente al estancamiento de la cobertura informativa sobre la guerra. Sus páginas expusieron un claro ejemplo de movilización de la comunidad y propusieron difundir, a través de notas bélicas, artículos científicos, literarios y recreativos, una versión alternativa de los acontecimientos y de la cultura alemana ante la presión de la propaganda aliada que controlaba la distribución de las noticias extranjeras en Argentina. En esta ocasión, se analizará cómo se expresaron las representaciones que pusieron en disputa valores alusivos a la nacionalidad y al amor a la patria asociados al militarismo alemán y de qué manera estos fueron representados para contrarrestar los argumentos de los enemigos.

Wetlands, known as 'Haors' in Bangladesh, are vital ecosystems that provide essential ecological services and support diverse biodiversity. However, they face increasing threats due to extensive tourists visits, unawareness about environment preservation and unsustainable development practices. The "Haor Eco-Interpretation Center" in Moulvibazar, Sylhet, Bangladesh, emerges as a pioneering initiative to address these challenges by combining environmental education and sustainable design principles.
This paper provides an overview of the Haor Eco-Interpretation Center's objectives, strategies, and significance. The center serves as a unique model for interpreting the Haor ecosystem while promoting sustainability through its architectural and operational features. The key elements of this initiative include visitor education, research facilities, and eco-sensitive design principles.

A phenomenon of Anax ephippiger (Burmeister, 1839) aggregation on the coast for the Strait of Gibraltar area, southern Iberian Peninsula, was recorded. Likewise, an annotated list of species recorded in Microreserve Arroyo Negro nearby to the Strait of Gibraltar is presented. Most of the species observed are thermophilic. The environmental and climatic conditions of this microreserve favor the settlement of African migratory species in a global warming scenario.
Participatory embeddedness and democratic deepening: Feminist Subaltern Counterpublics
Authors: Ureta García Miriam
Published: February 2024

The objective of this research is to analyze how participatory embeddedness through Feminist Subaltern Counterpublics is related to democratic deepening. To this end, two cases have been selected in the towns of Ripollet (Catalonia) and Etxebarri (Basque Country) developing a multi-method design that triangulates interviews, a direct observation and a discussion group. After applying a cross-case analysis, the findings reveal how the practical and spatial dimensions produce temporary rooting oriented towards democratic deepening from a gender perspective. Firstly, the dissolution of the public/private tension leads to inclusive practices and –therefore– to the politicization of subjects and problems previously excluded from the public sphere. Secondly, the institutionalization processes of social movements can favor spaces of hybridization where the concerns of the subalternized are mobilized in order to –thirdly– be transformed into public policies sustained over time.
El objetivo de esta investigación es analizar cómo se relaciona el arraigo participativo a través de los Contrapúblicos Subalternos Feministas con la profundización democrática. Para ello, se han seleccionado dos casos en los municipios de Ripollet (Cataluña) y Etxebarri (País Vasco) desarrollando un diseño multimétodo que triangula entrevistas; una observación directa y un grupo de discusión. Tras aplicar un análisis de casos cruzados, los hallazgos revelan cómo las dimensiones prácticas y de espacios producen enraizamiento temporal orientado a la profundización democrática desde una perspectiva de género. En primer lugar, la disolución de la tensión público/privada conduce a prácticas inclusivas y –por tanto- a la politización de sujetos y problemas anteriormente excluidos de la esfera pública. En segundo lugar, los procesos de institucionalización de movimientos sociales pueden favorecer espacios de hibridación en donde las preocupaciones del tejido social subalternizado son movilizadas para –en tercer lugar- ser transformadas en políticas públicas sostenidas en el tiempo.

Geoteknik mühendisliğinin en önemli problemlerinden biri olarak şev stabilitesine bağlı duraysızlık sonucu oluşan can ve mal kayıplarıdır. Şev stabiliteleri problemleri barajlar, yollar, şehirler veya dağ yamaçlarında görülmektedir. Şev duraysızlıklarına bağlı problemler ve kırılma mekanizmaları iyi anlaşılmalı ve buna göre çözümler geliştirilmelidir. Bu çalışmada kum zeminde bir şev geometrisine ait güvenlik katsayısı ve güvenlik katsayısına bağlı kırılma zonu analizi 9 farklı analitik yöntem(Ordinary/Fellenius, Bishop, Janbu, Janbu corrected, Spencer, Corps of Engineers, Corps of Engineers 2, Lowe-Karafiath, GLE/Morgenstern Price) ve Plaxis 2D programı ile analiz edilmiştir. Analiz sonuçlarına göre en yüksek güvenlik katsayısını veren analitik yöntem Janbu corrected ile 1.647 olmuştur. Çalışmada sonlu elemanlar analizi Plaxis 2D ile bulunan güvenlik katsayısı sonucu ise diğer analitik yöntemlerden daha yüksek olarak 1.665 olarak tespit edilmiştir. Gelişim halinde olan analitik yöntemler birim deformasyona bağlı sonlu elemanlar analizleri ile birlikte şev duraylılığını daha fazla parametre ile temsil ederek daha hassas ve ekonomik sonuç veren yeni bir formül geliştirilebilir.

The purpose of the current study is to examine the effects of personal inputs (gender, year in college, GPAs, and anxiety), background affordances (parents’educational level, household income, and role model), cognitive-person variables (self-efficacy and outcome expectations) and contextual influences (career barriers) on college students’career decision level in Social Cognitive Career Theory. A total of 230 participants’survey responses were analyzed. The results of hierarchical multiple regression analyses indicated year in college, role model, and outcome expectations positively predicted career decision levels and career barriers negatively predicted career decision levels. Implications for career counselors, researchers, professors, and administrators were discussed.
An Exploratory Study on Male Gender Role Conflict: Egalitarian Family Environment, Father Characteristics, Contact with Females
Authors:   The Institute of Educational research Chonnam National University, Sung Yoonhee
Published: February 2024

Compared to the extensive amount of research on the harmful effects of gender role conflict on men and others over the past few decades, relatively little attention has been given to examining factors that affect the formation of gender role conflict. Thus, the purpose of the present study was to explore the effects of egalitarian family environment(father s engagement in domestic chores, mothers power in financial decision-making), father characteristics(emphasis on success, emotional disconnection, lack of interest, violence, and mentorship), and contact with females(whether one has female siblings, proportion of female friends during middleand high school). Participants were 171 undergraduate and graduate male students from a university in a southern provincial area in South Korea. Results indicated the control variables and independent variables accounted for 15% of the variance in male gender role conflict. and that fathers violence and lack of interest were significant predictors of male gender role conflict. Limitations and directions for future research were discussed.

The physiological response in moss samples is often used as an early warning signal of environmental stress caused by air pollution. This study aimed to test the efficiency of photosynthesis-related parameters in Leucobryum aduncum moss bags as bioindicators of environmental stress related to road traffic. The moss samples were collected and prepared in a relatively unpolluted area and then transplanted at 7 sites in forested, rural, and urban areas. The moss samples were picked up after being exposed for 1 and 3 months for physiological measurements. The results showed that the average values of all physiological parameters were highest in the forested area and lowest in the urban area. All parameters at most roadside (R site) sites were lower or significantly lower than those at the site away from the road (A site). This was particularly true for the 3-month exposure period, suggesting that the length of exposure should be longer than 1 month, but exposure up to 3 months could fully damage the photosystem II (PSII) and destroy the moss bags. The vitality index (VI) also clearly indicated that the moss bags were more affected in the urban area, at the R sites, and at the 3-month exposure. Among all six parameters, the most susceptible parameter was the chlorophyll fluorescence parameter (Fv/Fm), followed by the total carotenoids, chlorophyll a, total chlorophylls, chlorophyll b, and chlorophyll a degradation (OD435/OD415). The moss bag technique used in this study did not negatively affect the studied physiological parameters, but a great elevation difference could affect the moss bag physiology. This study illustrated that the photosynthesis-related parameters of L. aduncum moss bags can be used as effective bioindicators of environmental stress caused by road traffic. This study is among the priority studies of moss bioindication of air pollution in Thailand and can pave the way for future studies.
