Coconut shell waste encased MnFe2O4 for enhanced microwave absorption

Radar systems, communication tools, and stealth technologies are just a few of the many areas that can benefit from microwave absorption materials (MAM). In an effort to promote sustainable and environmentally friendly solutions, researchers have turned their attention to waste materials as a potential resource for the development of efficient microwave (MW) absorbers. In order to lessen the effects of electromagnetic (EM) pollution, ferrites are frequently used as microwave-absorbing materials. However, the insufficient dielectric loss capacity is the fundamental constraint that limits their application. The MnFe2O4 was produced independently, while activated carbon (AC) was created using coconut shell. The MnFe2O4/AC composite was subsequently synthesized using a hydrothermal approach. From the research, the dielectric loss and magnetic loss of the S2 composite operate together. The incorporation of magnetic components contributes to the outstanding magnetic loss ability, while the nano-domain, hopping mechanism of the resonance effect is responsible for the improved dielectric qualities. S2 exhibits a minimum reflection loss of ‐38.4 dB at a thin thickness of 1.8 mm with an effective absorption bandwidth (EAB) of 6.2 GHz at the same thickness from 11.2 to 18 GHz. MnFe2O4/AC shows promise as a novel class of EM absorption materials because of their simple fabrication and high EM dissipation capacity.

Compendium of 5810 genomes of sheep and goat gut microbiomes provides new insights into the glycan and mucin utilization

BackgroundRuminant gut microbiota are critical in ecological adaptation, evolution, and nutrition utilization because it regulates energy metabolism, promotes nutrient absorption, and improves immune function. To study the functional roles of key gut microbiota in sheep and goats, it is essential to construct reference microbial gene catalogs and high-quality microbial genomes database.ResultsA total of 320 fecal samples were collected from 21 different sheep and goat breeds, originating from 32 distinct farms. Metagenomic deep sequencing and binning assembly were utilized to construct a comprehensive microbial genome information database for the gut microbiota. We successfully generated the largest reference gene catalogs for gut microbiota in sheep and goats, containing over 162 million and 82 million nonredundant predicted genes, respectively, with 49 million shared nonredundant predicted genes and 1138 shared species. We found that the rearing environment has a greater impact on microbial composition and function than the host’s species effect. Through subsequent assembly, we obtained 5810 medium- and high-quality metagenome-assembled genomes (MAGs), out of which 2661 were yet unidentified species. Among these MAGs, we identified 91 bacterial taxa that specifically colonize the sheep gut, which encode polysaccharide utilization loci for glycan and mucin degradation.ConclusionsBy shedding light on the co-symbiotic microbial communities in the gut of small ruminants, our study significantly enhances the understanding of their nutrient degradation and disease susceptibility. Our findings emphasize the vast potential of untapped resources in functional bacterial species within ruminants, further expanding our knowledge of how the ruminant gut microbiota recognizes and processes glycan and mucins.4UTuEuRwTx7UvdwKUcENuWVideo

Symptom domains and psychosocial functioning in borderline personality disorder

BackgroundBorderline personality disorder (BPD) is often characterized by severe functional impairment, even after a decrease in symptoms. A comprehensive understanding of psychosocial functioning in BPD is necessary to tailor treatment offer, which should address relevant aspects of daily life. The aims of the present study are to (1) conduct a cross-sectional comparison of functioning of a group with BPD and a non-BPD clinical comparison group at service entry, and to (2) assess the relationship between intensity of BPD symptom domains and psychosocial functioning.MethodsThe sample consists of N = 65 participants with BPD and N = 57 participants from the clinical comparison group without BPD (non-BPD group). The Revised Borderline Follow-up Interview (BFI-R) was used to evaluate psychosocial functioning and the Revised Diagnostic Interview for Borderlines (DIB-R) to assess BPD symptoms. Linear, logistic, and multinomial regression models were run separately for each aspect of functioning as a function of BPD status or BPD symptom domains.ResultsOnly 23% of participants in the BPD group fulfilled criteria for good overall psychosocial functioning, compared to 53% in the non-BPD group. Furthermore, participants in the BPD group were less likely to have completed a high number of years of education, to work consistently, to be financially independent, to be in a cohabiting relationship and have a good relationship with parents. In addition, various links were identified between BPD symptom domains and functional impairments.ConclusionsConsistent with prior research, the main impairments in functioning in the BPD group are found in the educational and vocational domains. Though some domains show impairment, others, like friendships, may act as potential resources. Further investigation on the relationships with symptom domains is required.

Exploring the Adaptation of Native Shrub Species to Different Levels of Shading: Augmenting their Sustainable Exploitation Framework

Abstract The environmental adaptation potential of regional wild germplasm resources should be investigated in a species-specific manner in terms of the sustainable exploitation of underutilized native species. In the current work, three fruit/ornamental shrub species (Rosa canina L., Sambucus nigra L. and Cornus sanguinea L.) originating from regional wild germplasm of Greece with a previously set domestication framework have been investigated in terms of their environmental adaptation to different levels of shading. To this end, targeted experimentation was conducted on ex situ adapted material by applying different shading levels (0%, 30% and 60% shading) in purpose-built netting tunnels. Rosa canina showed similar growth patterns among the shading levels applied but with increased chlorophyll fluorescence patterns and increased abaxial leaf stomatal density with increased shading. Sambucus nigra showed similar results to R. canina in photosynthetic efficiency and leaf stomatal density but with additional effects on plant growth patterns. Cornus sanguinea, on the other hand, was not affected by shading level in the measured parameters. These results outline the adaptation potential in a species-specific manner of the studied species to shading in terms of adding novel exploitation options for agroecosystems, agroforestry, and landscape management in peri-urban green spaces and peri-urban forest understory enrichment to mitigate climate change impacts in temperate and semi-arid climates. Study Implications: This study explores the adaptation potential to increasing levels of shading of ex situ adapted germplasm of wild origin of three underutilized shrub species with known multifaceted value. The work builds on the sustainable utilization framework of the focal species in terms of novel exploitation options in landscape management for peri-urban green spaces and peri-urban forest understory enrichment for enhancing biodiversity and soil erosion protection. Therefore, this work offers an example of an underlying research line towards systematized screening and utilization of wild plant species for climate change impact mitigation in agroecosystems, agroforestry, and landscape management in temperate semi-arid climates.

Strategizing Soft Skills Resilience: A Holistic Approach to Mitigating COVID-19 Pandemic Impact on Workforce Development

Student nurses' experiences with a digital educational resource supporting learning in nursing home placements: A qualitative study

BackgroundNursing education should improve clinical placements in nursing homes to foster and enhance student nurses' learning experiences. Initiatives for digital educational resource used to teach and supervise students to complement learning are increasingly being adopted and considered important in nursing education. However, little is known about how digital educational resources can facilitate learning in placements. Research on the value of such resources from student nurses' perspective is required. AimTo explore first-year student nurses' experiences with a digital educational resource developed to support learning in nursing home placements. DesignThis study has a qualitative explorative design and is part of a larger research project in which a digital educational resource named DigiQUALinPRAX was developed. SettingsThis study was conducted at three publicly funded nursing homes affiliated with one Norwegian university. ParticipantsTwenty-three first-year student nurses. MethodsData was generated through pre- and post-placement group interviews and analysed using reflexive thematic analysis. Standards for Reporting Qualitative Research were applied in this stud. FindingsOne overreaching theme and three subthemes related to student nurses' experiences with a digital educational resource were identified. The digital educational resource gave a feeling of being acknowledged as a learner by (1) providing a structure and preparation that made the placement feel less overwhelming, (2) supporting professional reflection and assessment practices, and (3) facilitating collaboration when all stakeholders used the resource actively. ConclusionsThis study indicates that student nurses' learning process in nursing home placements can be supported through digital educational resources customised for this learning arena. The findings indicate that the digital educational resource facilitated pre-placement preparedness, provided structure and flexibility, and enhanced reflection and assessment practices during clinical placement. However, encouraging tripartite usage is essential to exploit the full potential of digital educational resources.

Inversion of gas hydrate saturation and solid frame permeability in a gas hydrate-bearing sediment by Stoneley wave attenuation

Natural gas hydrate is a potential novel energy resource widely distributed globally. Acoustic logging can effectively provide information on the surrounding reservoir and plays an important guiding role in gas hydrate exploration and development. Natural gas hydrate-bearing sediments are composed of a solid frame with natural gas hydrates and water filled pores. The borehole mode wave characteristics of two-phase porous media can’t be used to evaluate the parameters of such a multi-phase porous medium. We explore factors that influence the monopole Stoneley wave in a borehole embedded in a multi-phase porous medium containing two solids and one fluid and analyze the influence of each factor on monopole Stoneley wave attenuation systematically. The sensitivity analysis results indicate that the Stoneley wave attenuation is highly sensitive to solid frame permeability and gas hydrate saturation. Building upon this foundation, a method to invert for gas hydrate saturation and solid frame permeability is first developed using Stoneley wave attenuation. Synthetic logging data is used to demonstrate the feasibility of this method for inverting for gas hydrate-bearing sediment properties. Even in the presence of considerable noise added to the receiver signal arrays, the inversion method is stable and reliably evaluates gas hydrate saturation and solid frame permeability.

Genomic insights into an endophytic Streptomyces sp. VITGV156 for antimicrobial compounds.

Endophytic Streptomyces sp. are recognized as a potential resource for valuable natural products but are less explored. This study focused on exploring endophytic Streptomyces species residing within tomato plants (Solanum lycopersicum) harboring genes for the production of a novel class of antibiotics. Our research involved the isolation and characterization of Streptomyces sp. VITGV156, a newly identified endophytic Streptomyces species that produces antimicrobial products. VITGV156 harbors a genome of 8.18 mb and codes 6,512 proteins, of which 4,993 are of known function (76.67%) and 1,519 are of unknown function (23.32%). By employing genomic analysis, we elucidate the genome landscape of this microbial strain and shed light on various BGCs responsible for producing polyketide antimicrobial compounds, with particular emphasis on the antibiotic kendomycin. We extended our study by evaluating the antibacterial properties of kendomycin. Overall, this study provides valuable insights into the genome of endophytic Streptomyces species, particularly Streptomyces sp. VITGV156, which are prolific producers of antimicrobial agents. These findings hold promise for further research and exploitation of pharmaceutical compounds, offering opportunities for the development of novel antimicrobial drugs.

The Effect of Cyberbullying on Stress and Productivity of Remote Employees During COVID-19

ABSTRACT The purpose of this study was to enhance our understanding of cyberbullying from a conservation of resources perspective with the goal of advancing theory and providing practitioners with information aimed at well-being interventions. We examined perceived stress as an explanatory mechanism of the relationship between cyberbullying and work productivity in remote workers. Information exchange frequency and quality were considered as potential resources that were hypothesized to mitigate this indirect effect. A sample of 269 adults in the United States who were working remotely as a result of COVID-19 were recruited through Amazon’s Mechanical Turk. The results of this time-lagged study indicated that cyberbullying did indeed exhibit an indirect effect on productivity via stress. However, contrary to expectations, this indirect effect was stronger for those with higher information exchange quality rather than lower information exchange quality. The indirect effect was unaffected by information exchange frequency. We encourage future scholars to dig deeper into when resources may be detrimental to employee well-being. We also encourage practitioners to consider ways to reduce both cyberbullying and worker stress with interventions such as technology etiquette training and careful planning of information exchange.

Influence of Marine Heatwaves on Upwelling Parameter in Indonesian Fisheries Management Area (IFMA) 713 Waters

Abstract An upwelling process linked to water productivity is likely to be affected by marine heatwaves (MHWs). The events of MHWs are distinguished by warmer sea surface temperature (SST), leading to increased stratification, causing vertical mixing limits and suppressing the upwelling process. In the Indonesian Fisheries Management Area (IFMA) 713 waters, which have enormous potential for fishery resources, five upwelling areas were identified during the southeast monsoon months (May–October) based on the Ekman pumping velocity (EPV) assessment, namely locations A (western part of West Sulawesi), B (southern Makassar), C (eastern part of Bone Bay), D (southern Banjarmasin), and E (southern Makassar Strait). Thus, this study aimed to investigate the influence of MHWs on upwelling parameter (chlorophyll-a concentration) in IFMA 713, particularly in 1998 and 2016, where prominent MHWs occurred and coincided with upwelling sessions. To accomplish this, EPV anomalies and chlorophyll-a concentrations for each MHWs event during May–October 1998 and 2016 were calculated. The analysis revealed that MHWs events co-occuring with negative (upwelling velocity is weaker than the climatological mean) and positive (upwelling velocity is stronger than the climatological average) EPV anomalies were associated with decreased chlorophyll-a concentrations.

Configuration of Carbonatite Constrained in Preintrusion Transpositional Foliation in the Bayan Obo Giant Rare Earth Element Deposit, China

Abstract The Bayan Obo ore deposit is the largest rare earth element (REE) deposit in the world and has been assumed to be hosted in dolomite that was folded in a syncline. This has been challenged by results from drill holes and low-resistivity, controlled-source audio-frequency magnetotellurics (CSAMT) survey. In this paper, we present structural analysis of clastic sedimentary rocks from around the deposit, their relationship with carbonatite, and the orientations of the carbonatite bodies and dikes to constrain the possible configuration of carbonatite. Clastic sedimentary rocks underwent mylonitic deformation to slate, metasandstone, and metaconglomerate, displaying dramatic changes of thickness along strike. Slates locally preserve intrafolial folds and hook folds bounded by foliations; metasandstones have parallel layers of recrystallized and preferred-orientated quartz aggregations; metaconglomerates contain flattened pebbles with Flinn k values of 0.01 to 0.05 and 0. The above structures and foliations were crosscut and intruded by carbonatite and associated fenite, demonstrating preintrusion transposition of original bedding to steep foliation. Preintrusion foliation provides zones of weakness that were exploited by upwelling of carbonatite magma. Northeast-SW–striking left-stepping en echelon carbonatite dikes and E-W–striking carbonatite bodies indicate that the carbonatite was emplaced in a sinistral transtensional zone. The northern and southern segments of the carbonatite bodies are parallel to the steep foliation at shallow depths and merge together at depth, constraining a Y-shaped configuration, consistent with the low resistivity result of the CSAMT survey. The newly recognized Y-shaped morphology indicates that the carbonatite extends deeper than 1,775.4 m, more than twice the previously inferred maximum depth of the syncline model, and contributes to a significant >1.78 times increase in global potential RE2O3 resources than previously estimated in 2021.

An assessment of the renewable energy potential of oil palm residues: A case study of CDC plantation, Cameroon

Cameroon faces enormous clean energy accessibility challenges despite abundant energy resources and huge quantities of free oil palm residues (OPR) generated but dumped yearly from the agro-industrial companies like the Cameroon Development Corporation (CDC). Presently, electricity supply is mainly from hydro (73 %) with accessibility of 65 % and 14 % for urban and rural areas respectively, while energy mix is historically dominated by traditional biomass fuels such as firewood and charcoal, accounting for more than 76 % of the country's total energy consumption. The hydro supply is not regular as it depends on weather conditions and this has negatively impacted the economy. The situation is aggravated by the increased energy demand over the past decade as Cameroon has engaged to become an emerging economy by 2035. However, encouraging policies for researchers and investors in the energy sector have been put in place with a view of attaining a 25 % share of renewable energy (RE) by 2035. OPR are a potential (RE) resource but require technical assessment and technological transformation into clean energy rather than dumping, which constitutes a serious environmental problem. This research has assessed the quantity of OPR generated annually at the CDC and estimated its clean energy value from 2004 to 2018 by consulting fruits-harvest records from CDC statistics office and by bomb calorimetry respectively. The significant findings reveal a yearly production of 203666T of OPR with a calorific value of 896 TJ, corresponding to electrical energy potential of 249 MWh. The energy could be used by the industry or injected into the grid to mitigate the current energy challenges.

This study aims to evaluate the knowledge depth and accuracy of these AI chatbots in cardiology using a multiple-choice question (MCQ) format. Methods: The study was conducted as an exploratory, cross-sectional study in November 2023 on a bank of 100 MCQs covering various cardiology topics that was created from authoritative textbooks and question banks. These MCQs were then used to assess the knowledge level of Google’s Bard, Microsoft Bing, and ChatGPT 4.0. Each question was entered manually into the chatbots, ensuring no memory retention bias. Results: The study found that ChatGPT 4.0 demonstrated the highest knowledge score in cardiology, with 87% accuracy, followed by Bing at 60% and Bard at 46%. The performance varied across different cardiology subtopics, with ChatGPT consistently outperforming the others. Notably, the study revealed significant differences in the proficiency of these chatbots in specific cardiology domains. Conclusion: This study highlights a spectrum of efficacy among AI chatbots in disseminating cardiology knowledge. ChatGPT 4.0 emerged as a potential auxiliary educational resource in cardiology, surpassing traditional learning methods in some aspects. However, the variability in performance among these AI systems underscores the need for cautious evaluation and continuous improvement, especially for chatbots like Bard, to ensure reliability and accuracy in medical knowledge dissemination.
