Technology-centred Discourses in European Audiovisual Policy: Will Euro-Techno out-Fox the US Assembly Line?
Authors: Gayoso Carmen Amelia.
Published: February 2024

This paper outlines the region-building initiatives of European audiovisual policy that are justified by a technology-centred discourse. While highlighting technology as a central and powerful theme in the European policy discourse, this paper begins to challenge the discourse’s depiction of reality. Specifically, the existing audiovisual environment suggests that notwithstanding Europeanization rhetoric in cultural policy decisions, there is a de facto Americanization of audiovisual space. Because of the apparent failure of the European Union to establish a unified competitive market, this paper analyzes the relationship between three variables competing in cultural policymaking. The first section lays out policy discourses characterized by European identity-formation. The second section describes the reality of cultural patterns in the EU that are characterized by diversity and audience fragmentation. The third section explains the reality of audiovisual space that is characterized by American products. A discussion follows of the restrictive effects that such policy discourse has on future policymaking decisions in the EU, bringing to question the success of any new policy orientation that is based around technology in both harmonizing European broadcasting policy and in rivaling its American competitor.

Opioid treatment agreements in chronic non-malignant pain: The solution or the problem?
Authors: Ho Jasper C , Bhogadi Yasovineeth
Published: February 2024

Opioid treatment agreements (OTAs) are routinely used in the primary care setting for patients initiating chronic opioid therapy for non-malignant pain despite limited empirical evidence supporting their use. In this commentary, we review the current practice guidelines in Ontario with regard to OTAs and evidence supporting their utilization in practice. We highlight the lack of high-quality evidence that OTAs lead to beneficial outcomes for patients or prescribing physicians and review the ethical quagmire they create in clinical practice. Physicians utilizing OTAs need to be aware of the limitations of OTAs and sensitive to their potential impact on the physician-patient relationship. Instead, we advocate for a return to a collaborative, patient-centered approach with physicians encouraged to involve patients in a shared decision-making process to set mutually agreeable goals for treatment with opioids, to obtain informed consent from patients, and to better tailor these agreements to reflect the interests of all parties involved. Further research and debate are required to improve the effectiveness and ethical justification for using OTAs in clinical practice.

Mnemonic but not contextual feedback signals defy dedifferentiation in the aging early visual cortex
Authors: Ehrlich Isabelle , Ortiz-Tudela Javier , Tan Yi You , Muckli Lars , Shing Yee Lee
Published: February 2024

Perception is an intricate interplay between feedforward visual input and internally generated feedback signals that comprise concurrent contextual and time-distant mnemonic (episodic and semantic) information. Yet, an unresolved question is how the composition of feedback signals changes across the lifespan and to what extent feedback signals undergo age-related dedifferentiation, i.e., a decline in neural specificity. Previous research on this topic has focused on feedforward perceptual representation and episodic memory reinstatement, suggesting reduced fidelity of neural representations at the item and category levels. In this fMRI study, we combined an occlusion paradigm that filters feedforward input to the visual cortex and multivariate analysis techniques to investigate the information content in cortical feedback, focusing on age-related differences in its composition. We further asked to what extent differentiation in feedback signals (in the occluded region) is correlated to differentiation in feedforward signals. Comparing younger (18 - 30 years) and older female and male adults (65 -75 years), we found that contextual but not mnemonic feedback was prone to age-related dedifferentiation. Semantic feedback signals were even better differentiated in older adults, highlighting the growing importance of generalized knowledge across age. We also found that differentiation in feedforward signals was correlated with differentiation in episodic but not semantic feedback signals. Our results provide evidence for age-related adjustments in the composition of feedback signals and underscore the importance of examining dedifferentiation in aging for both feedforward and feedback processing.

Significance StatementCognitive decline in aging is related to reduced neural specificity (dedifferentiation) in the brain, which has mainly been examined in feedforward processing. Using an occlusion paradigm, we tested whether there is dedifferentiation in contextual and mnemonic feedback signals internally generated in the early visual cortex to aid perception. Older adults’ contextual but not mnemonic feedback signals suffered from dedifferentiation, with semantic mnemonic representations being even better differentiated in older age. Neural differentiation between feedforward and episodic feedback signals was positively correlated in both age groups. In sum, these results highlight the growing importance of semantic knowledge across the lifespan and imply that the impact of dedifferentiation on cognition highly depends on the nature of the recruited information.
Age-related deficits in binaural hearing: Contribution of peripheral and central effects

Published: February 2024

Pure-tone audiograms often poorly predict elderly humans’ ability to communicate in everyday complex acoustic scenes. Binaural processing is crucial for discriminating sound sources in such complex acoustic scenes. The compromised perception of communication signals presented above hearing threshold has been linked to both peripheral and central age-related changes in the auditory system. Investigating young and old Mongolian gerbils of both sexes, an established model for human hearing, we demonstrate age-related supra-threshold deficits in binaural hearing using behavioral, electrophysiological, anatomical and imaging methods. Binaural processing ability was measured as the binaural masking level difference (BMLD), an established measure in human psychophysics. We tested gerbils behaviorally with “virtual headphones”, recorded single-unit responses in the auditory midbrain and evaluated gross midbrain and cortical responses using positron-emission tomography (PET) imaging. Furthermore, we obtained additional measures of auditory function based on auditory brainstem responses, auditory-nerve synapse counts, and evidence for central inhibitory processing revealed by PET. BMLD deteriorates already in middle-aged animals having normal audiometric thresholds and is even worse in old animals with hearing loss. The magnitude of auditory brainstem response measures related to auditory-nerve function and binaural processing in the auditory brainstem also deteriorate. Furthermore, central GABAergic inhibition is affected by age. Because the number of synapses in the apical turn of the inner ear was not reduced in middle-aged animals, we conclude that peripheral synaptopathy contributes little to binaural processing deficits. Exploratory analyses suggest increased hearing thresholds, altered binaural processing in the brainstem and changed central GABAergic inhibition as potential contributors.

Significance statementOlder people often have difficulty communicating in everyday situations involving multiple speakers and other sound sources. Binaural processing facilitates hearing in such complex listening situations. Peripheral damage, such as synapse loss in the inner ear, is thought to be an important factor contributing to these difficulties. However, the role of central processing deficits has received less attention. Here, we investigate age-related binaural processing in Mongolian gerbils using brainstem responses, midbrain single-unit responses, positron emission tomography, and reward-based animal psychophysics. Behavioral deficits in binaural processing precede increases in audiometric threshold, as do changes in central inhibition and physiological binaural processing. Synapse loss in cochlear regions tuned to the stimulus frequency, however, does not change and therefore unlikely contributes to age-related binaural deficits.
Oligodendrocyte Maturation Alters the Cell Death Mechanisms That Cause Demyelination
Authors: Chapman Timothy W. , Kamen Yasmine , Piedra Enrique T. , Hill Robert A.
Published: February 2024

Myelinating oligodendrocytes die in human disease and early in aging. Despite this, the mechanisms that underly oligodendrocyte death are not resolved and it is also not clear whether these mechanisms change as oligodendrocyte lineage cells are undergoing differentiation and maturation. Here, we used a combination of intravital imaging, single-cell ablation, and cuprizone-mediated demyelination, in both female and male mice, to discover that oligodendrocyte maturation dictates the dynamics and mechanisms of cell death. After single-cell phototoxic damage, oligodendrocyte precursor cells underwent programmed cell death within hours, differentiating oligodendrocytes died over several days, while mature oligodendrocytes took weeks to die. Importantly cells at each maturation stage all eventually died but did so with drastically different temporal dynamics and morphological features. Consistent with this, cuprizone treatment initiated a caspase-3–dependent form of rapid cell death in differentiating oligodendrocytes, while mature oligodendrocytes never activated this executioner caspase. Instead, mature oligodendrocytes exhibited delayed cell death which was marked by DNA damage and disruption in poly-ADP-ribose subcellular localization. Thus, oligodendrocyte maturation plays a key role in determining the mechanism of death a cell undergoes in response to the same insult. This means that oligodendrocyte maturation is important to consider when designing strategies for preventing cell death and preserving myelin while also enhancing the survival of new oligodendrocytes in demyelinating conditions.

Modelling of Mechanical Dewatering in Contact with Rough Permeable Surfaces
Authors:   STFI-Packforsk AB, Swedish Pulp and Paper Research Institute, Gustafsson Jan-Erik , Vomhoff Hannes ,   STFI-Packforsk AB, Swedish Pulp and Paper Research Institute
Published: February 2024

A model of the mechanical dewatering process during wet pressing was formulated that includes a non-uniform compaction at the interface between web and felt. This non-uniform compaction is assumed to be caused by the surface roughness of the felt. The model of the simultaneous deformation and flow in the fibre network was implemented in ABAQUS, a general finite element system. The dewatering behaviour of different rough permeable surfaces, representing model-felt surfaces, was investigated. Results obtained with the model showed the influence of the felt model surface on dewatering, especially at lower grammages. Here, the non-uniform compaction leads to a considerable decrease in obtained dryness. This decrease was more pronounced for rougher felts. In addition, each felt had an optimal dewatering behaviour at a certain grammage. In general, finer model felts performed better at lower grammage, which is in agreement with practical experiences in wet pressing.

Two physical phenomena which determine fundamental possibilities of paper forming are studied. The two phenomena are (i) laminar/turbulent transition and (ii) decay of turbulence. At first, the relevance of the processes to paper making is reviewed and discussed. The state of the boundary layers (laminar or turbulent) on split vanes and the decay of turbulence in the free stream are found to be of uttermost importance for the control of layer purity, formation and other properties of the final paper. Experiments in which these two processes are studied by visualisations are presented. The experiments emphasize the impact of fibres on these processes, as compared to what is found with pure water. All experiments are performed in model experiments were the structures in the flow are visualised by the addition of small, flake-like particles. It is shown that the addition of fibres radically change the physics of the flow. In a water table experiment, the addition of fibres is seen to promote the production of turbulent spots. At high enough fibre concentrations, the flow of water and fibres is fully turbulent even if a flow of pure water is laminar. In decay of turbulence, the fibres are seen to radically change the energy transfer between different scales so that intermediate and small scales remain active for longer times. It is concluded that fibres have large effects on laminar-turbulent transition and turbulence decay and that improved knowledge of these effects are a corner stone in the understanding of head box flow and its relations to the resulting paper quality.

STFI-Packforsk has recently patented the “Aq-vanes”, a new technology for stratified forming headboxes. In this new solution, a thin passive liquid layer (a liquid vane or “Aq-vane”) is injected in the headbox between neighbouring pulp streams through a narrow hollow channel, thereby preventing mixing between the layers. One of the most interesting features of the Aq-vane technology is that layer purity and separation can be controlled externally by tuning a set of process parameters. This opens the field for a widespread industrial application of stratified forming, a paper maker’s quantum leap that may reduce energy and raw material consumption, lead to improved product properties and possibly even to the development of new grades. In fact, although the basic concept of producing an engineered layered structure is not new in papermaking; its application has been extremely limited to a few selected grades, such as high grammage paperboard or multi-layer tissue. The Aq-vanes have been implemented on EuroFEX, STFI-Packforsk’s research paper machine, for extensive pilot scale trials. Thereby a number of technical solutions for the injection of the liquid layer has been tested and evaluated. In a parallel project, a method for measurement of layer purity in stratified forming has been developed. It is based on sheet splitting using a heat-seal pouch lamination technique. An image analysis method is then used to identify the colour of the fibres and thus the layer mixing.

This paper introduces a new concept for digitizing the three dimensional paper structure, based on a fully automated microtomy process and light microscopy. The microscope can be moved in all three directions of space with high accuracy in order to be able to digitize large samples with high spatial resolution. All components are controlled by a PC interface which enables an automated digitization process. The literature concerning 3D analysis of paper structure is reviewed. Non destructive and destructive techniques are compared. Image analysis algorithms for creation of a detailed digital representation are described. This digital data set is analyzed, to derive characteristics of the paper structure. As a first example of possible applications the analysis of the 3D coating layer formation is presented. The coating layer is detected by means of image analysis based on a 3D color segmentation concept. Initial experiments on analyzing coated paper samples prove the applicability of the concept. The correctness of the implemented sample digitization process and following image analysis was validated.

Published: February 2024

Our society is in the age of the fourth industrial revolution and it is becoming a goal of education to cultivate creativity and personality in order to cultivate future human resources. Therefore, the purpose of this study is to learn about movie education as one of the education that can cultivate creativity and personality, and to examine how to conduct movie education in early childhood education. Through the literature search, we investigated the current state of elementary and secondary movie education, the current state of Korean film education for early childhood, and discussed future issues. There were various cases of development of National Film Education Standards in elementary and secondary education, but film education in early childhood education was not enough. Research using movies was limited to watching movies at the beginning, and research to produce movies was simply to film the theatricals. Therefore, we proposed the scenario writing through various storytelling, self expression through film appreciation and production, and the development of early childhood teacher training program.

Children s TV programs in China had already begun in 1958 with the . However it had slowed down under the Cultural Revolution and started to be active in the early 1980s. Since the establishment of the animation production agency for the first time in 1984, China had produced a variety of works. Since the 1990s, it had produced infant and child programs in various formats and contents. Since then, Children s TV programs in China had made great strides, from securing broadcasting channels to operating experimental programs, but have also presented various problems. In this study, the problems of Chinese infant and child TV programs were reviewed based on the research results in China. Topics such as Children should participate in the TV program as subjects, TV programs should be suitable for children’s development, Children’s TV programs should reflect the characteristics of the local community, “Children’s TV programs should meet the balances between education and entertainment,” Children’s TV programs should reflect China s tradition were argued. Basically the five issues discussed in this study were regarding children’s TV programs in China. However those problems were closely related with problems of children’s TV programs in Korea and early childhood education in general.

Missing outcome data in clinical trials may jeopardize the validity of the trial results and inferences for clinical practice. Although sick and preterm newborns are treated as a captive patient population during their stay in the NICUs, their long-term outcomes are often ascertained after discharge. This greatly increases the risk of attrition. We surveyed recently published perinatal and neonatal randomized trials in 7 high-impact general medical and pediatric journals to review the handling of missing primary outcome data and any choice of imputation methods. Of 87 eligible trials in this survey, 77 (89%) had incomplete primary outcome data. The missing outcome data were not discussed at all in 9 reports (12%). Most study teams restricted their main analysis to participants with complete information for the primary outcome (61 trials; 79%). Only 38 of the 77 teams (49%) performed sensitivity analyses using a variety of imputation methods. We conclude that the handling of missing primary outcome data was frequently inadequate in recent randomized perinatal and neonatal trials. To improve future approaches to missing outcome data, we discuss the strengths and limitations of different imputation methods, the appropriate estimation of sample size, and how to deal with data withdrawal. However, the best strategy to reduce bias from missing outcome data in perinatal and neonatal trials remains prevention. Investigators should anticipate and preempt missing data through careful study design, and closely monitor all incoming primary outcome data for completeness during the conduct of the trial.
Interactional functions of laughter in assisted reproductive medicine consultations
Authors: Bigi Sarah , Tedone Amanda , Vegni Elena
Published: February 2024

Doctor –couple interactions in the context of assisted reproductive medicine frequently include occurrences of laughter, especially patient-initiated. These have been examined in previous studies from a quantitative perspective and in relation to specific topics, but not as regards the functions that laughter realises throughout the interactions. Our study aims to address this underinvestigated issue by providing an analysis of a small sample of consultations (n = 10) about assisted reproductive technology (ART) treatments. The analysis is set within a discourse-interactional perspective on clinical interactions, which focuses on consultations as advice-seeking activities in which advice-giving is the main discourse type. The consultations have been analysed through structural mapping, which has revealed five main phases: opening, information sharing, problem identification, discussion of the options and closing. Laughter tokens have been identified and their functions are described from the point of view of an incongruity-based framework. The interactional functions of laughter described in this framework, e.g., ‘marking incongruity’, ‘softening trouble-telling’, ‘showing sympathy’, ‘marking irony’ etc., have then been mapped onto the different phases of the consultations, yielding a fine-grained description of when laughter occurs and what participants are using it for. Our study expands on previous analyses of laughter in ART consultations, offering a novel methodological approach that could be applied to larger corpora.

Study ability of protection effect of organic acids for multi-metallic anti-corrosion additive system in ethylene glycol-water coolants
Authors: Pham Thi Mai Huong  , Nguyen Thi Huong
Published: February 2024

In this work, the electrochemical behavior of carbon steel, brass, bronze and aluminum alloys in the presence of various important organic acids (sebacic acid (SbA), terephthalic (TPA), 2-ethylhexanoic (E2C6A), and octanoic (C8A)) and the effect that these have on the growth and protectiveness of the alloys have been investigated. The results show that the presence of organic acids in the coolant increases the protective effect of the system by forming a film on the surface of the alloys. The EIS impedance results demonstrate the formation of active and passive protective layers on the surface of the alloys. The results of surveying 04 types of organic acids for the protection of different alloy substrates show that TPA and SbA acid additives are more effective than C8A and E2C5A. The additive C8A not only did not inhibit corrosion but also promoted this process strongly, especially with aluminum alloys and the TPA has the best anti-corrosion effect for steel, followed by C1 copper alloy and aluminum.
Modern software capabilities for shape optimization of shells
Authors: Ermakova Evgenia , Rynkovskaya Marina
Published: February 2024

The article is devoted to the shape optimization of shell structures in Comsol Multiphysics using three gradient-based methods: IPOPT (Interior Point OPTimizer), SNOPT (Sparse Nonlinear OPTimizer) and MMA or GCMMA (the Method of Moving Asymptotes). Two types of complex shapes, such as right helicoid and developable helicoid are taken for the computational experiment. The task is to investigate the initial design and optimization process of two helicoids. To obtain a more accurate result and an interesting design solution, the calculation is carried out using three physics-controlled mesh sizes: extra coarse, fine and extra fine with varying values of special optimization settings, such as maximum displacement (dmax) and filter radius (Rmin). The results obtained using the three methods allow to conclude that the mesh element size and studied parameters dmax and Rmin have a significant impact on the final optimization result.

A worldwide review of the impact of COVID-19 disruptions on learner development and resilience
Authors: Malindi Macalane Junel , Hay Johnnie
Published: February 2024

The COVID-19 pandemic necessitated school closures and movement restrictions that disrupted holistic development and adaptive coping in learners worldwide. Adaptive coping is also referred to as resilience. Holistic development covers the biophysiological, psychological, social, spiritual and educational domains of child development. Several researchers have explored the impact of developmental risks caused by school closures and movement restrictions on learner development. With this article we aim to present a synthesis of these reviewed papers. We reviewed 81 peer-reviewed papers that were published globally from 2020 to 2023. The focus of these papers was on biophysical, psychological, social, religious and academic development in learners. We did not develop a priori themes to guide us; instead, themes emerged from the articles that were reviewed. The findings show that although the lockdown restrictions were aimed at preventing the spread of the virus and saving lives, the imposed restrictions affected the development of learners in biophysiological, psychological, social, educational and religious domains. Furthermore, the findings show that the impact of the lockdown necessitated multisystemic interventions on different levels to enable learners to overcome backlogs and promote resilience.

Como discussões, ressalta-se que a devoção parte de uma sepultura com características inerentes a uma escola específica do Budismo japonês. Entretanto, o túmulo foi apropriado pelos fiéis de diferentes formas, desenvolvendo uma devoção à santa de cemitério que articulou distintas camadas religiosas presentes na sociedade brasileira.

RESUMO: O conjunto dos Direitos Humanos é uma resposta direta às práticas totalitárias de extermínio de seres humanos, fruto de uma racionalidade técnico-instrumental durante a Segunda Guerra Mundial (1939 - 1945). Assim, este artigo busca investigar se a educação é uma estratégia adequada para a formação de uma Cultura multidimensional em Direitos Humanos baseada no compartilhamento intersubjetivo de valores, sem uso da força/violência ou da superioridade política/econômica como elementos promotores do comum. Inicia-se com a apresentação de alguns conceitos e características a respeito da educação e dos Direitos Humanos. Em seguida, apresenta-se a multiplicidade de fundamentos e dimensões da Educação em Direitos Humanos - EDH, conforme delineado a partir da segunda metade do século XX, em documentos internacionais e nacionais. Por fim, são abordadas as principais características de uma cultura-mundo técnico-instrumental e as possibilidades de transformação social por meio da interação humana intermediada pela comunicação. O artigo desenvolve-se em uma abordagem dialética, utilizando como técnica a revisão de literatura, que subsidia a discussão de conceitos e a análise de alguns documentos jurídicos. Após o percurso investigativo, conclui-se que a EDH é estratégia multidimensional para promoção de uma Cultura de Direitos Humanos ao reforçar os aspectos comuns da humanidade, produzindo consensos em torno da dignidade humana, do respeito e da inclusão, sem recurso ao uso da força, da ameaça ou da opressão.

ABSTRACT: In Brazil, certain studies have been performed on the exposure to global occupational noise levels when mechanized equipment is used in coffee-growing. However, these did not indicate the behavior within a frequency spectrum (Hz) by octave bands. The objective of this study was to assess the sound pressure levels of the brush, mower, and atomizer attached to a tractor under actual operating conditions by using 1/1 octave band filters. Quantitative assessments were performed with the mower, brush, and atomizer attached to the MF 275 tractor under two conditions: operative and static. The noise levels obtained under actual operating conditions were determined using a DOS 1000 noise dosimeter and an octave band filter. The static condition assessments were performed inside and outside the coffee plantation using a Hikari HDB 900 digital sound level meter. The NR 15 and NHO 01 standards were used to analyze the data. Under operative and static conditions, the tractor units showed noise levels above the exposure limit of 85 dB (A) for an 8h working day. The assessment of the frequency spectrum revealed the highest noise levels to be in the 125-1000 Hz range.

RESUMO Nos últimos anos a preocupação de ambientalistas vem crescendo devido ao grande uso de produtos que tem como matéria-prima fontes fósseis não renováveis. Uma alternativa adotada entre os pesquisadores é a produção de compósitos de matriz termoplástica com fibras de resíduos de lignocelulósicas. A oiticica ou oiti é um fruto rico em óleo e é muito utilizado para a produção de sabão. O co-produto gerado desse processo é rico em fibras, óleo e impurezas e atualmente é muito utilizado para ração animal e adubo para solo. O objetivo do presente trabalho é a produção e avaliação das propriedades de compósitos de PEAD com Torta de Oiticica. Como matriz foi utilizado um PEAD verde fornecido pela Braskem e a fase dispersa foi a Torta de oiticica fornecida por uma fábrica de sabão. As composições com 5, 10 e 20% de Torta de oiticica foram processadas por extrusão dupla rosca e os corpos de provas confeccionados pelo processo de injeção. Os compósitos foram caracterizados através do ensaio de tração uniaxial para avaliação de propriedades mecânicas (deformação até a ruptura, módulo e tensão na força máxima). A interação entre torta e matriz foi analisada através da superfície de fratura utilizando microscopia eletrônica de varredura e a análise térmica foi avaliada através de DSC. Os resultados mostraram diminuição na deformação para composições com 10 e 20% de torta. Houve uma queda gradativa na tensão na força máxima nos compósitos quando comparada com a do PEAD. As micrografias mostraram pouca interação entre fibra e matriz e a presença de vazios. As análises térmicas apresentaram uma diminuição no grau de cristalinidade. concluindo-se que a presença da torta pode ter dificultado a organização das cadeias, gerando maior número de regiões amorfas.

Abstract Rhynchophorus palmarum (Coleoptera: Curculionidae) is a significant agricultural pest in palm plantations across tropical America, playing a critical role as a vector of the fungus Thielaviopsis paradoxa, which is the causative agent of stem bleeding disease in coconut palms. This disease has raised concerns due to its rapid spread and subsequent reduction in coconut production in northeastern Brazil. Additionally, this insect can establish mutualistic interactions with various fungi, including saprophytic, phytopathogenic, and entomopathogenic fungi, underscoring the importance of identifying its external mycobiota. The aim of this study was to assess the presence of T. paradoxa in the digestive tract and identify the cultivable mycobiota associated with the carapace of R. palmarum. To achieve this, a mycological study was conducted by culturing the external surface and digestive tract of field-caught adult insects (10 males and 10 females) on potato dextrose agar (PDA) in Maceió, Alagoas, Brazil. Fungal identification was performed by correlating microscopic features with the macroscopic characteristics of the obtained colonies. The results showed that T. paradoxa was detected in 15.0% of carapace isolates but was not found in the insects' intestinal tract. Additionally, nine fungal genera frequently associated with saprophytic or phytopathogenic behaviors were identified on the carapace. Eight of these genera belong to the Ascomycota phylum, while one is classified in the Basidiomycota phylum. The ubiquitous presence of Paecilomyces spp. and the occurrence of Trichosporon spp. in 95% of the assessed insects stand out. Furthermore, other potentially phytopathogenic fungi such as Penicillium spp., Fusarium spp., and Aspergillus spp., as well as fungi with entomopathogenic potential like Paecilomyces spp., Trichoderma spp., Metarhizium spp., and Beauveria bassiana, were detected. These findings enhance the understanding of the complex interactions between R. palmarum and its fungal hosts, providing insights for integrated pest management strategies.
