AbstractThe present work aimed to study the yeast communities of whole crop corn silages (CS) that were previously contaminated with aflatoxin-producing Aspergillus flavus (CSCA). In addition, the effect of lactic acid bacterium (LAB) inoculation on the aflatoxin B1 (AFB1) content, genotoxicity, yeast load, and diversity of yeast communities were also investigated. In A. flavus contaminated silages, after two months, the AFB1 content was 40% lower with LAB inoculation, also a lower level of genotoxicity was determined. The number of yeasts cultured from the initial mixture of chopped whole crop corn was 4.8 × 107 CFU g−1 wet mass, while only 2.4 × 106 CFU g−1 from the CSCA and 7.1 × 105 CFU g−1 from the LAB-inoculated CSCA could be cultured. Based on 144 randomly isolated strains, the yeast community of the initial mixture consisted of 8 species. In contrast, the yeast community of CSCA consisted only of 4 species determined by 132 randomly selected isolates. LAB-inoculated CSCA consisted also of 4 species based on 158 randomly isolated strains. Saccharomyces cerevisiae and Pichia kudriavzevii proved to be predominant in the CSCA, while S. cerevisiae and Meyerozyma guilliermondii were the most abundant in the LAB-inoculated CSCA. The species richness was also confirmed by alpha diversity values (1.827, 1.188, and 1.123 as Shannon's indices for CS, CSCA, and LAB-inoculated CSCA, respectively). In response to LAB inoculation, the species diversity decreased considerably.

Abstract
Heterostructures of two-dimensional (2D) materials comprise clean van der Waals (vdW) interfaces that can facilitate charge or energy transfer. Recently, the 2D ferroelectric CuInP2S6 (CIPS) has been integrated with graphene and other 2D materials to realize potentially novel low energy electronic devices. However, the influence of 2D CIPS on the properties of graphene and doping across the vdW interface has not been studied in detail. Here, we study graphene field effect transistors (FETs) with CIPS as the top gate. We find that CIPS leads to modulation of the graphene Fermi level due to local doping. We also find polarization-induced hysteresis in CIPS-gated graphene FETs. Electrical transport measurements from 50 to300 K show that above 200 K, the ferroelectric response decreases. As a result, the hysteresis voltage windows in the graphene ferroelectric FETs (FeFET) transfer curves decrease above 200 K. Our results show that interfacial remote doping affects the macroscopic polarization and performance of CIPS-based graphene FeFETs.

Highlights

This research studies the temperature-dependent local doping across a vdW ferroelectric/2D channel interface that affects the transport properties of ferroelectric field effect transistors (FeFETs).

Experimental findings showed ferroelectric polarization switching-based hysteresis in CuInP2S6-gated graphene FeFETs.

Discussion

vdW ferroelectrics that can be scaled to atomic layer thicknesses are useful for miniaturised low energy electronics.

Understanding the interface charge or energy transfer in vdW ferroelectrics is essential for their integration into current or future technologies.

Ante la prevalencia de comportamientos machistas y estereotipos de género en los diversos ordenamientos jurídicos de países de América Latina, Objetivo: analizar a profundidad la influencia que tienen los mismos en las decisiones judiciales, en especial de los casos de feminicidio. Lo que se describe y analiza en este artículo es cómo, en diversos casos representativos, los operadores de la justicia (hombres) no prestan atención suficiente a los hechos de violencia de género o no responden con las acciones pertinentes para proteger los derechos de las mujeres, lo que conduce, en muchos casos al feminicidio. Método: se aplicó un enfoque documental y descriptivo, ya que a través de fuentes primarias y secundarias se abordó la influencia de los macro y micromachismos en la toma de decisiones judiciales por parte de las autoridades que se ven implícitas en los casos de feminicidio ocurridos en América Latina, decisiones con perspectiva de género. Resultados: a partir de lo encontrado en el proceso de investigación, se evidencia la necesidad imperiosa de fortalecer las instituciones encargadas de investigar los casos de violencia de género y feminicidios, además de intensificar la educación en perspectiva de género de los funcionarios públicos que prestan sus servicios en los entes protectores del Estado. Conclusiones: los Estados no combaten verdaderamente el feminicidio, este es un problema complejo y multifacético, y la efectividad de los esfuerzos estatales para combatir el feminicidio hacen que muchas veces los feminicidio queden impunes, en términos de sentencias judiciales, se pudo observar como los tribunales en América latina abordan tanto los factores individuales (micro machismos) como los patrones estructurales más amplio (Macro-machismo) que contribuyen al feminicidio esto puede reflejarse en la interpretación de la ley, la valoración de la prueba y las decisiones sobre la culpabilidad y las penas.

Background. The modern stage of training highly qualified athletes is characterized by the introduction of technologies into the training process aimed at effective planning and monitoring of training effects. This technology considers programming, which provides an ordered content of the training process, taking into account the main components of training loads.
Objectives. The study purpose was to experimentally determine the effectiveness of building a training process for highly qualified field hockey players at the stage of direct preparation and participation in the main competitions of the sports season based on programming methods.
Materials and methods. A total of 21 highly qualified field hockey players involved in the study. The participants had attained the rank of sports qualification — Master of Sports of Ukraine. The athletes’ mean age was 25.6 ± 5.29 years. The study was conducted in 2021 during the preparation and participation of the Ukrainian national field hockey team in the European Championship “Championship 2” (Gniezno, Poland). The scientific search was carried out on the basis of the following methods: theoretical analysis and generalization of scientific and methodical literature; pedagogical observation, pedagogical testing, and methods of mathematical statistics.
Results. The stage structure of direct preparation and participation in the main competitions of the sports season for highly qualified field hockey players was determined. It consisted of three mesocycles: basic — 4-day retractable microcycle, 4-day shock microcycle, 3-day recovery microcycle; special training — 4-day shock microcycle, 3-day recovery microcycle, 4-day preparatory microcycle; competitive — 7-day competitive, 3-day recovery microcycles.
Conclusions. One of the most rational technologies for training athletes is programming, which ensures an ordered content of the training process, taking into consideration the key elements of training loads. Programs of training tasks were developed, which became the basis for micro- and mesocycle programs.
Interpersonal Semiotics of Music after Several Decades
Authors: Doubravová Jarmila 
Published: August 2024

Interpersonal semiotics of music belongs to the sphere of musical anthropology. It is based on introspection and experiments with different types of music and different groups of respondents. Its theoretical principle represents the theory of small social group and system of interpersonal tendencies by Knobloch and Knoblochová (1999). This is used in relation of I/Other in which ‘Other‘ means music. Some works of B. Bartók, A. Berg, L. Janáček, B. Martinů, J. Sibelius, I. Stravinsky and J. Suk were analysed and described, among others, on this ground, i.e. from the point view of my interpersonal testimony. The interpersonal analyses of Czech music of the 1950s by several groups of respondents confirmed that such testimonies are distinguishable. The presented survey represents results of long work as part of my diverse semiotic and aesthetic activities.
Role of Critical Realism in Uncovering Breastfeeding Experiences of Mothers Affected by Disaster and Displacement: Researcher’s Reflections
Authors: Hirani Shela Akbar Ali 
Published: August 2024

Objectives:Ontology is a study of what is the reality or truth about a phenomenon. The ontological assumption of critical realism is grounded in the belief that human behavior, actions, and perceptions are shaped by a wide range of social structures and underlying mechanisms that are interrelated and complex. This article presents researcher’s reflections drawn from the findings of a study that used critical realism as a theoretical lens in exploring the breastfeeding facilitators and barriers of the internally displaced mothers in a low–middle-income country where natural disasters are prevalent and there is a dearth of research on factors that impede or facilitate breastfeeding practices of mothers during disasters and displacement.Methods:Using critical realism as a theoretical lens, a qualitative study was undertaken in postdisaster settings of Pakistan. After seeking ethical approval, multiple methods were utilized to collect data, including field observation, document analysis, and in-depth interviews (40–60 minutes each) with 18 displaced mothers who were residing in temporary housing in northern Pakistan and facing struggles due to recurrent disasters in that region.Findings:The findings suggested a wide range of structural factors at displaced mothers’ microsystems (maternal factors), mesosystems (sociocultural factors), exosystems (economic factors), and macrosystems (geopolitical factors) that directly and indirectly affect their breastfeeding practices during disaster and displacement. The findings uncovered the need for multilayered breastfeeding-friendly initiatives to promote, protect, and support breastfeeding in postdisaster settings. Some of these interventions include enhancing maternal knowledge on breastfeeding through awareness programs in local languages, clarifying myths and misconceptions surrounding breastfeeding, providing mental health and nutritional support to displaced mothers, creating breastfeeding-friendly spaces during disasters, offering culturally sensitive healthcare and humanitarian aid, empowering local people to promote breastfeeding culture, and restricting unmonitored donation of formula milk during disasters.Conclusion:The ontological assumption of critical realism provided an opportunity to gain insight into a reality that is multifaceted, complex, and interrelated. A comprehensive understanding of a range of maternal, sociocultural, economic, and geopolitical factors from this study will help nurses, lactation consultants, breastfeeding advocates, service providers, and policymakers in developing context-specific interventions to improve breastfeeding practices and decrease child deaths during disaster and displacement. The findings hold implications for the future programs, practices, and policies to protect breastfeeding practices of mothers affected by disaster and displacement.

Intensive reading helps students to understand the meaning of a word and is one of the college courses that is useful in learning. In this study, the researcher identified the difficulties and strategies used by EFL learners in intensive reading. The objective of this research was to identify the difficulties and the strategies used by EFL learners in intensive reading. The research used a qualitative case study that attempted to identifying reading difficulties and strategies among EFL learners in intensive reading. The researcher analyzed the data using thematic analysis model adopted from Braun and Clarke (2006). The result of this research showed that the students’ difficulties were divided into two types: reading difficulties related to learning goals and psychological barriers. When difficulties arise in the areas of learning objectives that students can use to guide their performance with these objectives, it can hinder students' reading comprehension. Studies also found that students face reading difficulties related to psychological barriers such as attention deficits, poor retention, lack of self-confidence, lack of motivation and shyness. The result of this research is expected to be able to give meaningful contributions for, teachers or lecturers, EFL learners and other researchers.
Are There Non-invasive Biomarker(s) That Would Facilitate the Detection of Ovarian Torsion? A Systematic Review and Meta-Analysis

Published: August 2024

Ovarian torsion (OT) is a rare gynaecological emergency that requires a prompt diagnosis for optimal patient management. To determine whether there were any biomarkers suitable for the non-invasive detection of OT, two independent reviewers performed systematic searches of five literature databases following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Full-texts of 24 selected articles were assessed for risk of bias and quality assurance using a modified Newcastle-Ottawa Scale (NOS). 15 articles described studies on animals and all described serum biomarkers comparing results between OT versus a sham operation, a control group or readings before and after OT. Ischaemia modified albumin (IMA), serum D-dimer (s-DD), heat shock protein-70 (hsp-70), Pentraxin-3 (PTX-3) and c-reactive protein (CRP) showed the most promise, each with p-values for the difference between groups achieving ≤0.001. In studies of humans, the biomarkers ranged from 16.4-92.3% sensitivity and 77-100% specificity. The most promising biomarkers for the early prediction of OT in patients included s-DD, interleukin-6 (IL-6), IMA and tumour necrosis factor-alpha (TNF-. IL-6 had the highest sensitivity of any biomarker identified in this review and was raised in all 13 patients with proven OT, with values of ≥10.2pg/ml, indicative of a 16 times higher risk of having OT. Signal peptide, CUB domain and EGF like domain containing 1 (SCUBE1) had a high specificity at 93.3%, second only to s-DD and a positive likelihood ratio (LR)&amp;gt;10. IMA was the only other biomarker that also had a positive LR&amp;gt;10, making it a promising diagnostic biomarker. The studies identified by this systematic literature review each analysed small patient groups but IMA, DD and SCUBE1 nevertheless showed promise as serum biomarkers with a pooled LR&amp;gt;10. However, further well-designed studies are needed to identify and evaluate individual markers, or diagnostic panels to help clinicians manage this important, organ-threatening condition.

Published: August 2024

SummaryThe effects of chemical additives on mitigating water blocking and improving oil recovery were experimentally examined for gas-water and oil-water systems in spontaneous imbibition cells. In these attempts, two factors are critically important: (1) understanding the physics of the interaction, whether it is co- or countercurrent, and (2) characteristics of the chemical additives to suitably orient the interaction for specific purposes (accelerate/decelerate matrix-fracture interactions). Co- and countercurrent imbibition experiments were conducted on sandstone rock samples using various oil samples (viscosities between 1.37 cp and 54.61 cp) as well as gas (air). The selected new-generation chemical additives included deep eutectic solvents, cationic/anionic/nonionic surfactants, and inorganic and organic alkalis. We observed that the functionality of the chemicals varied depending on the fluid type, interaction type (co- or countercurrent), and application purposes. For instance, chemicals such as the cationic surfactant cetyltrimethylammonium bromide (CTAB) significantly reduced water invasion into the gas-saturated sandstone cores during fracturing, while chemicals such as the nonionic surfactant Tween® 80 provided considerable oil recovery improvement in the oil-saturated sandstone cores. The surface tension and wettability of the rock surface are crucial factors in determining the suitability of chemicals for mitigating water blockage. In terms of oil recovery, certain chemical additives, such as O342 and Tween 80, may result in a lower recovery rate in the early stage because of their strong ability in interfacial tension (IFT) reduction but could lead to a higher ultimate recovery factor by altering the wettability. Additionally, the introduction of chemicals resulted in notable spontaneous emulsification, especially in countercurrent imbibition, thereby enhancing oil recovery. The spontaneous emulsification and its stability are influenced by factors such as oil drop size, boundary condition, interaction type, IFT, wettability, as well as rock surface charges. The results have implications for understanding the physics and dynamics of matrix-fracture interactions in co- and countercurrent conditions. In addition, they serve as the first step toward selecting appropriate chemical additives in hydraulic fracturing fluid design and enhancing oil recovery in unconventional reservoirs.

Abstract

The advent of the ultra-first digital system marked a transformative era in technology, particularly in monitoring natural phenomena through electromagnetic waves. For safeguard of the electronic instruments and mitigate electromagnetic interference, the utilization of electromagnetic absorbing materials has emerged as a crucial solution. In this context, the Moringa Oleifera fiber (MOF) which is exploded away as a waste material has the potential to disseminate the intensity of high intense electromagnetic wave plays a crucial role in presence of reduced graphene oxide (rGO) with epoxy as (rGO/MOF/EPOX) composite stand out as a promising approach. When incorporated into an epoxy matrix, MOF form a synergistic blend that not only provides electromagnetic shielding but also offers mechanical strength and stability. The change of complex permittivity of the material from 3.2 to 3.35 with 1wt% of rGO, produces a remarkable reflection loss along with increase of absorption efficiency from 68.38 % to 87.41%.The morphology of rGO/MOF/EPOX composite are analyzed through SEM which supports the ability of the composite to be a good electromagnetic shielding material. The physical, mechanical and thermal property MOF/EPOX composite has been evaluated in presence of rGO and discussed with correlation of dielectric properties of the material.

Abstract

The next-generation stretchable displays require a new class of multifunctional electrode materials that simultaneously attain high elasticity, reliable tensile stability, and superior electrical conductivity. Despite their outstanding electrical conductivity, conventional metal thin-films often suffer from limited elasticity, typically less than 1%. Conversely, amorphous alloys offer exceptional elasticity, but their electrical resistivities do not meet industrial requirements. In this work, we propose metallic nanolaminates composed of alternately-stacked Al-based amorphous alloys and nanocrystalline elemental Al layers as a novel kind of electrode material suitable for stretchable displays. These materials are designed to synergistically combine the mechanical properties of amorphous alloys with the electrical properties of crystalline Al, and can be synthesized using currently available mass production fabrication facilities. Through in-situ scanning electron microscopy nano-tension experiments, we demonstrate the nanolaminate samples achieve a unique combination of a high elastic limit approaching 3%, large tensile elongation exceeding 17%, and excellent electrical resistivity lower than 10 µΩ·cm.
