Published: January 2025

Irrigation is essential for increasing agricultural productivity in Indonesia, directly impacting national food security and farmer welfare by ensuring the sustainability of irrigation systems. Despite its importance, significant challenges persist, including damage to 46% of the irrigation infrastructure across 7.1 million hectares, with responsibilities divided among central, provincial, and city governments. These challenges are compounded by issues such as inadequate information access, limitations in real-time monitoring, and poor stakeholder coordination. To address these issues, integrating technological tools such as Geographic Information Systems (GIS) and platforms such as OpenStreetMap (OSM) is essential. These technologies offer real-time information, facilitate land change tracking, and enable spatial mapping, which supports proactive management and planning while improving decision making through data-driven insights. The adoption of Rapid Application Development (RAD) and Decision Support Systems (DSS) further enhances the efficiency of irrigation system management. The RAD methodology ensures swift development cycles with user interaction, while DSS provides structured decision-making capabilities. This approach supports robust system design, user interface development, and geographic data visualization. In practice, efficient data collection and stakeholder participation enable the system to effectively report and track irrigation conditions, promoting public participation, and fostering long-term infrastructure sustainability. The developed online monitoring system demonstrates its effectiveness by providing interactive map features and transparent reporting platforms, verified through successful implementation of testing scenarios. This system not only improves infrastructure management in areas like Batu City, but also sets a precedent for scalable participatory irrigation solutions, creating a foundation for future enhancements.
From gaps to transaction: Reflections on a long-term collaborative research practice in VET
Authors: Wegener Charlotte , Thomassen Anja Overgaard
Published: January 2025

The purpose of this article is to reflect on and theorise collaborative research practices. Research–practice collaborations are widely recognised and encouraged by means of university strategies, policy intentions, and funding requirements. One way to provide for and strengthen collaborative research in education is to form long-term partnerships between schools and universities. In this reflective account, we draw on our own experiences from doing research in the field of vocational education and training (VET) as participants in a long-term collaboration among two social and health care vocational colleges and two university departments. Assisted by Dewey’s pragmatic approach to learning as transaction, we seek to move beyond the binary of ‘research’ and ‘practice’ as constituting a gap to be bridged between two forms of knowledge. Instead, we conceive of the collaboration as an emerging ‘third context’ in its own right created by various activities, all of which involve both theoretical and experiential knowledge.

Published: January 2025

Submerged artificial sandbars (SABs) are increasingly favored as an efficient method for beach nourishment, helping to mitigate beach erosion and maintain the sediment transport budget, thus promoting ecological stability. A comprehensive understanding of the morphodynamical evolution of the submerged artificial sandbar-beach profile is essential. This study employs a scaled-down moving-bed flume test to examine the dynamic geomorphological evolution of the submerged artificial sandbar-beach system under regular wave conditions. Twenty experiments, each with different wave heights and periods representative of the Zhejiang coast, were conducted. The study investigated the profile evolution and wave parameters of the submerged artificial sandbar-beach model. The results reveal low wave reflection in front of the sandbar, indicating that under the tested wave conditions, the sandbar primarily serves as a sediment source rather than effectively reflecting wave energy. In all scenarios, the top of the sandbar migrates shoreward, and the sandbar’s contour shape becomes asymmetric. For smaller wave periods, localized erosion occurs in the troughs, while larger periods result in complete siltation. Continuous sediment transport into the trough characterizes the beach face, with sediment movement controlled by wave height and period. A linear or nonlinear relationship between sandbar erosion depth, beach slope, and wave parameters (height, period) is established, providing an empirical model for SAB-beach profiles. These findings enhance the understanding of SAB-beach systems and offer valuable insights for coastal protection and disaster prevention in engineering applications.
Prognostic and clinicopathological significance of mucin family members expression in gastric cancer: a meta-analysis
Authors: Wang Shunda , Mu Yongrun , Zhang Jianwei , Wang Chengfeng
Published: January 2025

Background

Mucin family members have been reported to be widely expressed in gastric carcinoma with diverse functions. Several important mucins exert the function of tumorigenesis or progression in gastric cancer (GC). Here, we conduct this meta-analysis to evaluate the association between mucin expression and clinicopathological features in GC.

Methods

Literature searches were performed in PubMed, Embase, The Cochrane Library, and ISI Web of Science, and, finally, 28 studies met our criteria. Odds ratios or hazard ratios with 95% confidence intervals were calculated to evaluate the effect quantity. We analyzed the expression of MUC1, MUC2, MUC5AC, and MUC6 and their clinicopathological characteristics separately at the same time.

Results

Twenty-eight studies that contain 4,603 patients were included in our meta-analysis. MUC1 was associated with gender, Lauren classification, depth of tumor invasion, TNM, vascular invasion, lymph metastasis, and lymphatic invasion, WHO grade, as well as the 5-year survival rate. MUC2 was significantly correlated with lymphatic invasion and WHO grade. MUC5AC was highly positive in gender, depth of tumor invasion, WHO grade, TNM, lymph metastasis, and lymphatic invasion. Moreover, cases with decreased MUC5AC expression were correlated with less 5-year survival. MUC6 was only related with lymphatic invasion.

Conclusion

Our meta-analysis showed that MUC1 and MUC5AC had prognostic value in GC detected by immunohistochemistry. MUC1 and MUC5AC were also associated with some other significant clinicopathological parameters. Moreover, MUC2 and MUC6 also exert their influence in lymphatic invasion. However, further enlarged study awaits to verify our conclusion to deeply explore the role of mucin family members in GC.

Authors: Mortan Laura F. , Meelheim Brooke A. , Garland Justin , Bohn Jacqueline A. , Isingizwe Zitha Redempta , Benbrook Doris M.
Published: January 2025

Background/Objectives

Patients with ovarian cancer commonly experience metastases and recurrences, which contribute to high mortality. Our objective was to better understand ovarian cancer metastasis and identify candidate biomarkers and drug targets for predicting and preventing ovarian cancer recurrence.

Methods

Transcripts of 770 cancer-associated genes were compared in cells collected from ascitic fluid versus resected tumors of an ES-2 orthotopic ovarian cancer mouse model. Associated cell types and pathways were explored with bioinformatics. FGF7 protein was measured using capillary-based immunoassays or ELISA in mouse and clinical specimens. Significances of differential gene expression and patient prognosis were determined by volcano plot and log-rank test, respectively.

Results

Tumor transcriptomes exhibited higher endothelial cells, oxygenation, proteasome activity, and metabolism in comparison to ascites, but similar percentages of cancer-associated fibroblasts and immune cells. FGF7 mRNA was significantly higher in mouse tumors compared to ascites. FGF7 protein was significantly higher in tumors than in ascites in independent mouse models and clinical specimens. Serum FGF7 protein levels above the median of 25 patients with ovarian cancer were associated with worse progression-free and overall survival (p = 0.005 and 0.019, respectively) independent of patient and tumor characteristics.

Conclusions

In comparison to ascites, tumors exhibit different transcriptomic profiles that identify candidate biomarkers and drug targets for predicting and preventing recurrence. Among these, elevated tumoral FGF7 validated at the protein level and elevated serum FGF7 were significantly associated with worse patient survival. These results support further development of FGF7 receptor-targeted drugs and serum FGF7 to prevent and predict recurrence, respectively.
Assessment of genetic conservation units of an endangered glacial relict insular species, Amentotaxus formosana, based on fine-scale genetic structures of multiple fragmented mountainous populations in Taiwan

Published: January 2025

Insular species are usually endemic and prone to long-term population reduction, low genetic diversity, and inbreeding depression, which results in difficulties in species conservation. The situation is even more challenging for the glacial relict species whose habitats are usually fragmented in the mountainous regions. Amentotaxus formosana is an endangered and endemic relict tree species in Taiwan. It is typically found scattered across different mountain regions, leading to fragmented and discontinuous populations in various habitats. Consequently, reproductive isolation may lead to deep and cryptic population structures between and within populations. To test this hypothesis and assess the most effective conservation units for the species, comprehensive genetic analyses were conducted using multiple microsatellite loci to uncover fine-scale population structures in three mountainous regions. In this study, a substantial sample of over 600 individuals, predominantly middle-aged, was collected, representing a majority of the existing individuals in the Chachayalaishan and Dawu habitats. Population genetic structure analyses were conducted using three complementary Bayesian clustering approaches (STRUCTURE, InStruct, and GENELAND) to ensure robust identification of distinct genetic clusters in three key habitats (CHA, DAWU, and DL). Results indicated low genetic diversity, distinct genetic differentiation, and severe inbreeding within fragmented populations. Additionally, demographic analysis suggested a substantial downfall in effective population sizes and limited gene flow within and between populations. Based on these findings, we recommend several management strategies to ensure the effective preservation of A. formosana: (1) establishing genetic conservation units corresponding to distinct genetic clusters in the CHA (CG-8-1 to CG-8-8), DAWU (DG-15-1 to DG-15-15), and DL (LG-6-1 to LG-6-6) populations; (2) implementing interpopulation cross-breeding programs to enhance genetic diversity; (3) promoting habitat restoration efforts to establish connectivity among fragmented populations; and (4) implementing vegetative propagation of selected trees for ex-situ conservation, along with establishing conservation nurseries and seed production areas. These localized conservation approaches, combined with the comprehensive genetic insights provided by this study, serve as crucial directives for the genetic monitoring, policy formulation, and sustainable conservation of A. formosana.
Unveiling the conserved nature of Heliconia chloroplast genomes: insights from the assembly and analysis of four complete chloroplast genomes
Authors: Cheng Xin , Shi Chengcheng , Yang Ting , Ge Qijin , Kress W. John , Liu Xin
Published: January 2025

Introduction

Heliconia, a genus within the Zingiberales order, is renowned for its diverse morphology, suggesting a rich genetic reservoir. However, genetic research on plants within the Heliconiaceae family has primarily focused on taxonomy and phylogenetics, with limited exploration into other genetic aspects, particularly the chloroplast genome. Given the significance of chloroplast genomes in evolutionary studies, a deeper understanding of their structure and diversity within Heliconia is essential.

Methods

In this study, we sequenced and assembled the complete chloroplast genomes of four representative Heliconia species: Heliconia bihai, Heliconia caribaea, Heliconia orthotricha, and Heliconia tortuosa. The chloroplast genomes were analyzed for structure, gene content, and nucleotide diversity. We also performed comparative analysis with other species within the Zingiberales order to investigate structural and functional differences.

Results

The assembled chloroplast genomes of the four Heliconia species exhibited a typical quadripartite structure and ranged in length from 161,680 bp to 161,913 bp. All genomes contained 86 protein-coding genes. Comparative analysis revealed that the chloroplast genome structures of the different Heliconia species were highly conserved, with minor variations. Notably, the chloroplast genome of Heliconia was slightly shorter than those of other Zingiberales species, primarily due to the reduced length of the inverted repeat region. In terms of nucleotide diversity, Heliconia species exhibited lower diversity in their chloroplast genomes compared to other families within the Zingiberales order.

Discussion

This study provides valuable insights into the conserved nature of the chloroplast genome in Heliconia. The reduced chloroplast genome size, particularly the shortened inverted repeat region, marks a distinct feature of Heliconia within the Zingiberales family. Our findings also underscore the low nucleotide diversity within the chloroplast genomes of Heliconia species, which could be indicative of their evolutionary history and limited genetic differentiation. These results contribute to a broader understanding of chloroplast genome evolution in the Zingiberales and offer important genetic resources for future research on Heliconia and related species.

Authors: Bell Suzanne T. , Anderson Steven R. , Roma Peter G. , Landon Lauren Blackwell , Dev Sheena I.
Published: January 2025

While there is a large body of research on social support in traditional work settings, less is known about how the unique context of long-term isolation and confinement affects perceived social support. The purpose of our research was to examine how perceptions of social support change over time, how they differ by source (i.e., public, organization, family/friends/colleagues, and other crewmembers), and the relationship between social support and stress. We collected data from 64 crewmembers in five spaceflight analog campaigns with restricted communication with outside sources. Results suggested that perceived social support declined over time for all sources, with declines more pronounced for external sources (public, organization, family/friends/colleagues) than for perceived support from other crewmembers. While perceived overall social support was unrelated to stress over time, social support from crewmembers was related to the stress levels reported by crewmembers in the evening. Our results are important as they: (a) empirically document the decline in perceived social support over time in extended isolation; (b) provide evidence for the critical importance of the role of fellow crewmembers in being able to provide social support in conditions of extended isolation and communication delay; and (c) underscore the need to more fully understand the dynamics between the crew and external sources of social support (public, organization, family/friends/colleagues) as well as how those relationships may be best supported for individuals who live and work in long-term isolation and confinement.

Authors: Liu Gang , Liu Ya , Chen Zongping , Zhou Siyuan , Ma Lingfei
Published: January 2025

The current study employed network analysis to examine the relationship between symptoms from factor level about autism traits and problematic mobile phone use (PMPU) and to explore their associations with depression. We measured the above three variables in 949 college students in China with Autism Spectrum Quotient (AQ), Smartphone Addiction Scale (SAS), Center for Epidemiological Studies Depression Scale (CES-D). Central and bridge symptoms were pinpointed through the examination of centrality index. In the AQ and PMPU network, results revealed that WD (“Withdrawal”), COR (“Cyberspace-oriented relationship”) and OU (“Overuse”) emerged as the core symptoms. AS (“Attention switching”), CO (“Communication”) and COR (“Cyberspace-oriented relationship”) were the most symptoms bridging the AQ and PMPU communities, suggesting that these symptoms could serve as focal points for interventions aimed at college students with concurrent autism traits and PMPU. SK (“Social skills”), COR (“Cyberspace-oriented relationship”), CO (“Communication”), and DLD (“Daily-life disturbance”) were most strongly associated with depression. In addition, future research should consider various measurement tools and methods to investigate the location of AD (“Attention to detail”), because AD was an isolated symptom in the flow network of depression.

A case study of two Shanghai metro stations, Xinzhuang and Xujiahui, was conducted using quantitative metrics, surveys, and interviews.

Results

A strong correlation between AHP scores and SUS ratings validated the framework’s reliability. The study provides recommendations for enhancing metro accessibility.

Discussion

The proposed framework offers a robust tool for evaluating and improving urban transit accessibility, with implications for inclusive mobility policy and design.
Numerical Modeling and Structure Optimization for Magnetic Levitation Planar Machine Using PCB Coils
Authors: Zhang Han , He Jiawen , Xu Xianze , Wang Rui , Xu Manman , Xu Fengqiu
Published: January 2025

Magnetically levitated (ML) systems that incorporate PCB coils represent a growing trend in precision machining, valued for their controllable current flow and high fill factor. The size of modern power devices is decreasing to enhance power density, minimize parasitic inductance, and reduce power losses. However, due to the high resistance of PCB coils, managing heat generation has become a significant area of study. This paper seeks to optimize PCB coil design to minimize power loss and control peak temperatures in ML systems, using a numerical model. An improved magnetic node model is employed to construct the magnetic fields of an ML system. The proposed optimization method considers the interdependencies among parameters to reduce overall power loss from coil resistance and switching losses in the H-bridge circuit, while enhancing heat dissipation efficiency in steady-state operation. A heuristic multi-objective optimization algorithm is employed to optimize the design of the ML actuator. The optimization process initially focuses on the PCB coils, with the magnet size held constant. Once the optimal coil parameters are identified, the magnet volume is optimized. By integrating a theoretical analysis with simulation, this approach effectively addresses the optimization challenges and achieves the desired performance for the ML actuator. Coils and magnets are constructed based on the optimized design and tested by the magnetic field simulation software Radia, confirming the feasibility of the approach. The method was also applied to a different type of ML system for comparison, demonstrating the universality of the proposed strategy. In this optimization effort, the maximum temperature reduction reached an impressive 50 °C

Published: January 2025

Collaborative flight formations represent a promising operational model, but the integration of multi-source information in manned interfaces often results in cognitive overload and reduced situation awareness. This study evaluates the effectiveness of intelligent auxiliary information presentation modes in enhancing personnel capabilities. Using a simulation-based collaborative flight formation system, four presentation modes with varying levels of information and dynamics were experimentally tested and evaluated across subjective dimensions (cognitive workload, situation awareness, and interface design) and objective dimensions (design task flow information load and operational task flow information load). The results indicate that Level 3 and Level 4 modes significantly reduced mental workload and improved practical operational ability compared to the original mode. Level 3 achieved the highest interface evaluation scores, while Level 4 demonstrated the lowest design task flow information load. Both modes significantly enhanced situation awareness. Altogether, Level 3 and Level 4 resulted in the most significant improvements in personnel capabilities. These findings provide valuable insights for optimizing interface design and improving situation awareness in collaborative flight formation tasks.
Damped Iterative Explicit Guidance for Multistage Rockets with Thrust Drop Faults

Published: January 2025

A damped iterative explicit guidance (DIEG) algorithm is proposed to address the problem of the insufficient convergence of classical explicit guidance methods in the event of thrust drop faults in multistage rockets. Based on the iterative guidance mode (IGM) and powered explicit guidance (PEG), this method is enhanced in three aspects: (1) an accurate transversality condition is derived and applied in the dimension-reduction framework instead of using a simplified assumption; (2) the Gauss–Legendre quadrature formula (GLQF) is adopted to increase the accuracy of the method by addressing the issue of excessive errors in calculating thrust integration using linearization methods based on a small quantity assumption under fault conditions; and (3) a damping factor for solving the time-to-go is introduced to avoid the chattering phenomenon and enhance convergence. A numerical simulation was conducted in single- and multistage mission scenarios by gradually reducing the engine thrust to compare the performance of DIEG and PEG. The results show that DIEG has a much larger convergence range than PEG and has fuel optimality similar to that of the optimization method in most fault scenarios. Finally, the robustness of DIEG under various deviations is verified through Monte Carlo simulation.

Published: January 2025

The aim of this study was to evaluate the effect of sunflower cake from high-oleic seeds on performance, carcass characteristics, meat quality, and intramuscular fatty acid composition of finishing lambs. Thirty-six crossbred ewe lambs were assigned to four treatments (nine lambs/treatment) in a completely randomized design: 0 (control), 150, 300 and 450 g/kg DM of high-oleic sunflower cake. The lambs were weighed weekly and slaughtered with 42.3 ± 0.18 kg body weight and 270 ± 10.8 days of old. The inclusion of sunflower cake did not affect weight gain, dry matter intake and metabolizable energy intake (p > 0.05). There was an increase in neutral detergent fiber and EE intake (p < 0.01) with the inclusion of sunflower cake in the diet of the lambs. The inclusion of sunflower cake reduced hot and cold carcass yields (p < 0.01). Intramuscular fat content, L*, oleic acid, rumenic acid and EPA fatty acids linearly increased (p < 0.01) with the inclusion of high-oleic sunflower cake. The inclusion of high-oleic sunflower cake reduced saturated fatty acids (p < 0.01), except stearic acid, which linearly increased (p < 0.01). Up to 450 g/kg DM of high-oleic sunflower cake in the diet of lambs did not affect animal performance while providing a higher deposition of fat with better fatty acid composition for human consumption.
Novel Breeding Techniques and Strategies for Enhancing Greenhouse Vegetable Product Quality
Authors: Weiss Julia , Gruda Nazim S.
Published: January 2025

With its controlled environment, protected cultivation is advantageous and effective for breeding programs. This distinct setting also guarantees that fresh vegetables meet high quality standards. The controlled environment allows for precise monitoring and tuning of breeding efforts, a critical factor in continuously improving the quality of fresh vegetable production. Classical breeding strategies include hybridization, pedigree selection, backcrossing, recombination, and marker-assisted breeding. However, advanced techniques like phenomics and genome editing are revolutionizing the field. These methods accelerate phenotyping and aid in identifying traits and genetic variants linked to quality characteristics. Modern biotechnological tools, specifically genetic engineering and gene editing methods like CRISPR/Cas, have enhanced a wide array of traits in numerous vegetable species. These technological advancements have the potential to effectively address challenges associated with stress resistance, product quality, and shelf-life, thereby presenting promising prospects for the advancement of agriculture. The protracted process of developing new vegetable cultivars with reduced physiological issues through contemporary techniques is an enduring endeavor.
Peroxiredoxin 5 Acts as a Negative Regulator of the Sodium-Chloride Cotransporter Involved in Alleviating Angiotensin II-Induced Hypertension
Authors: Choi Hoon-In , Jung In Ae , Kim Soo Wan
Published: January 2025

Chronic kidney disease (CKD) and hypertension are interconnected, worsening each other. Recent studies have shown that the reduction of peroxiredoxin 5 (Prdx5) accelerates kidney fibrosis, a hallmark of CKD. This study aims to observe whether the deficiency of Prdx5 also contributes to the worsening of CKD-related hypertension. Angiotensin II (Ang II, 1000 ng/kg/day) was infused into Prdx5 wild-type (WT) and Prdx5 knock out (KO) mice (each group; n = 6). The blood pressure was higher in the Ang-II-infused Prdx5 KO mice than in the WT mice. Ang-II-induced ROS/RNS generation and fibrotic marker expressions were also higher in the Prdx5 KO mice. In particular, the expression of the sodium-chloride cotransporter (NCC), an ion transport protein important for sodium retention in the distal convoluted tubule, and the NCC’s phosphorylation at Thr53 were increased in the kidney of Ang-II-infused Prdx5 KO. The activity of an WNK4-SPAK/OSR1, upstream activator of the NCC, was also increased. In 209/mDCT cells, the knockdown of Prdx5 (siPrdx5) increased the activity of Ang-II-mediated WNK4-SPAK/OSR1-NCC signaling and Ang-II-mediated ROS generation, whereas Prdx5 overexpression showed opposite results. In conclusion, Prdx5 negatively regulates the WNK4-SPAK/OSR1-NCC signaling axis, indicating its potential as a candidate for antihypertensive drug development through NCC regulation.

Water-based nutrient injection technology, widely used in sectors like viticulture, hydroponics, and intensive animal systems, has previously seen limited application in livestock production. Early mechanical dispensers for nutrients, such as non-protein nitrogen (NPN) and phosphorus (P), were prone to malfunction, leading to inconsistent dosing and potential livestock health risks. This contributed to skepticism and slow adoption among producers. However, recent technological advancements have renewed interest in water-based supplementation for grazing animals. This case study assessed the use of water injection technology to deliver nutrients and a methane-reducing compound to cattle on a commercial cattle station under extensive grazing conditions. A total of 120 steers [initial liveweight (LW) 322.5 ± 28.3 kg] were assigned to three groups: water only (Control), a water supplement containing nutrients such as nitrogen and phosphorus, known as uPRO GREEN® (Green), and uPRO GREEN® combined with Agolin Ruminant L® (Blue). The experiment lasted 90 days, during which LW was continuously monitored via a walk-over weighing system, and water disappearance was measured at the mob level. Methane emissions were forecasted using dry matter intake estimates based on observed animal growth rates. Additionally, 24 steers were equipped with on-animal sensors with GPS to monitor behavioral changes. The results indicate that despite the potential reduction in water intake (Control and Green: 948.1 and 973.5 L/d, respectively, versus 547.5 L/d for Blue), there were no negative effects on growth (mean average daily gain of 1.32 kg/d) or animal behaviors. The predicted methane emission of 209.04 g CH4/head/day could potentially be reduced by 10–15% with the compound used in the current trial. These findings suggest that water-based supplementation can be used to optimize nutrient delivery and a methane-reducing compound without compromising cattle productivity in extensive grazing environments. In addition, the potential enteric methane mitigation presents an opportunity for livestock producers to generate additional revenue through carbon credits or to create new markets for beef with low greenhouse gas emissions when cattle consume methane-reducing compounds.

Fungi are a typical part of the microbiome of poultry houses, but some of the genera can be pathogenic for poultry and humans. An investigation was conducted on 200 duck eggs from 10 flocks to determine total fungal contamination on the eggshells. The colony types were identified morphologically and microscopically, and a representative group was identified using PCR. The resistance profiles for all obtained Aspergillus isolates were conducted. The dominating genera on eggshells were Penicillium, Alternaria and Aspergillus and the number of fungal colonies ranged from 0 to 7100. Aspergillus fumigatus was cultured from 9.5% eggshells, and all isolates were obtained from three flocks. The minimum inhibitory concentration (MIC) values for A. fumigatus isolates ranged from 0.094–32 μg/mL for amphotericin B (MIC 50 1 mg/L and MIC 90 32 μg/mL), 0.125–32 μg/mL for caspofungin (MIC 50 0.38 μg/mL and MIC 90 32 μg/mL), 0.19–32 μg/mL for itraconazole (MIC 50 1.5 μg/mL and MIC 90 32 μg/mL), 0.047–12 μg/mL for posaconazole (MIC 50 0.5 μg/mL and MIC 90 8 μg/mL) and 0.023–32 μg/mL for voriconazole (MIC 50 0.19 μg/mL and MIC 90 32 μg/mL). A total of 73.7% of the isolates were resistant to posaconazole and 68.4% to itraconazole. Nearly half of the strains (47.4%) showed resistance to amphotericin B and 31.6% to voriconazole. Because of the lack of antifungals registered for poultry, hygiene and the regular disinfection of litter in particular are needed to prevent the contamination of the eggs by fungi for both animal and human health.

This study considered how these solutions impact urban aesthetics, functionality, and energy efficiency. The research methods used include visual analysis, a literature review, and technological analysis of the kinetic systems used. The results show that movement at elevations can be achieved using various tools and can affect energy efficiency and building layout, in addition to having visual impacts. This study concluded that it is important to integrate new technologies into urban design and called for further research into the long-term impacts of changeable elevations on the urban environment.
Investigation of Vertical Profiles of Particulate Matter and Meteorological Variables up to 2.5 km in Altitude Using a Drone-Based Monitoring System
Authors: Kim Woo Young , Lee Sang Gu , Lee Handol , Ahn Kang-Ho
Published: January 2025

In this study, a drone-based measurement system equipped with miniaturized optical and condensation particle counters was deployed to investigate the vertical distribution of particulate matter and meteorological variables up to 2.5 km in altitude. Measurements captured at various altitudes demonstrated notable vertical variations in particle concentration and significant correlations with meteorological factors, particularly relative humidity (RH). Near the surface, within a well-mixed boundary layer, particle concentrations remained stable despite RH changes, indicating both anthropogenic and natural influences. At higher altitudes, a clear positive relationship between RH and particle number concentration emerged, particularly for smaller particles, while temperature inversions and distinct wind patterns influenced aerosol dispersion. The unmanned aerial vehicle system’s robust performance, validated against standard meteorological tower data, underscores its potential for high-resolution atmospheric profiling. These insights are crucial for understanding particle behavior in diverse atmospheric layers and have implications for refining air quality monitoring and climate models. Future work should incorporate chemical analysis of aerosols to further expand these findings and assess their environmental impact.
Effect of Multiple Injection Strategy Under High Ammonia Ratio on Combustion and Emissions of Liquid Ammonia/Diesel Dual DI Engine
Authors: Chen Zhenbin , Wan Yudong , Awad Omar I. , Pan Zhiqiang
Published: January 2025

With the increasingly prominent environmental and energy issues, emission regulations are becoming more stringent. Ammonia diesel dual fuel (ADDF) engine is one of the effective ways to reduce carbon emissions. This study investigated the effect of multiple injection strategy on the combustion and emission characteristics of liquid ammonia/diesel dual direct injection (DI) engines through numerical simulation. The results showed that under the condition of maintaining the same pre injection diesel fuel and high ammonia energy ratio (80%), with the introduction of multiple injection, the peak cylinder pressure decreased and the peak phase advanced, the combustion start angle (CA10) advanced, the heat release showed a multi-stage pattern. The times of injection (TSOI) has a significant effect on combustion and emissions. As TSOI increased, ignition delay decreased, the combustion duration is shortened, and the combustion is accelerated. Notably, overall emissions of NOx and N2O have decreased, but the emissions of unburned NH3 have increased. Optimized the state of ammonia injection (SOAI) timing and ammonia injection pressure (AIP), showed that advancing SOAI timing and increasing AIP improved combustion. Advanced the SOAI timing to −8 °CA ATDC, resulted in a significant NOx emissions decrease with an increase in TSOI, reaching over 50%. Although increasing injection pressure can improve combustion, it also results in higher N2O emissions.

Complex mixtures of air pollutants, including ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), black carbon (BC), and fine particulate matter (PM2.5), present significant health risks. To understand the factors influencing air pollution levels and their temporal variations, comprehensive high-resolution long-term air pollution data are essential. This study analyzed the characteristics, lagged meteorological effects, and temporal patterns of six air pollutant concentrations over a one-year period at an urban residential site in Kenitra, Morocco. The results reveal pronounced seasonal and diurnal variations in pollutant levels, shaped by meteorological factors, emission sources, and local geographic conditions. PM2.5, SO2, and CO concentrations peaked during winter, while NO2 and CO exhibited consistent diurnal peaks during morning and evening rush hours across all seasons, driven by traffic emissions and nocturnal pollutant accumulation. In contrast, O3 concentrations were highest during summer afternoons due to photochemical reactions fueled by strong UV radiation, while winter levels were the lowest due to reduced sunlight. Lagged meteorological effects further highlighted the complexity of air pollutant dynamics. Meteorological factors, including temperature, wind speed, humidity, and pressure, significantly influenced pollutant levels, with both immediate and lagged effects observed. Lag analyses revealed that PM2.5 and BC levels responded to wind speed, temperature, and humidity over time, highlighting the temporal dynamics of dispersion and accumulation. CO is sensitive to temperature and pressure changes, with delayed impacts, while O3 formation was primarily influenced by temperature and wind speed, reflecting complex photochemical processes. SO2 concentrations were shaped by both immediate and lagged meteorological effects, with wind direction playing a key role in pollutant transport. These findings emphasize the importance of considering both immediate and lagged meteorological effects, as well as seasonal and diurnal variations, in developing air quality management strategies.
The Feshbach Resonances Applied to the Calculation of Stark Broadening of Ionized Spectral Lines: An Example of Interdisciplinary Research
Authors: Sahal-Bréchot Sylvie , Elabidi Haykel
Published: January 2025

In the present paper, we revisit the determination of Feshbach resonances in the elastic and fine-structure cross-sections of the spectral lines of ionized atoms colliding with electrons. The Gailitis approximation will be recalled and used to calculate the Feshbach resonances. A historical point of view will be used, emphasizing the interest of interdisciplinary research, with a back and forth between physics and astrophysics. First, the theory of Feshbach (arising at end of the 1950s and beginning of the 1960s) resonances will be briefly recalled and applied to the calculation of the cross-sections. In the beginning of the 1970s, the insertion of Feshbach resonances in spectroscopic diagnostics calculations permitted researchers to interpret the intensities of solar coronal lines. Then, in the middle of the 1970s, this gave rise to the idea of including the Feshbach resonances in the calculation of electron impact broadening (the so-called “Stark” broadening) of isolated spectral lines of ionized atoms. Finally, in the recent example of the Stark broadening of the Mo VI 5d D5/22−5p P°3/22 line, the S-matrices will be calculated using the semi-classical perturbation formalism and will be compared to those of the more recent quantum distorted wave formalism.

Background: Tinnitus is a frequent symptom, and is present in 10–15% of people who suffer from chronic tinnitus, defined as heard every day for at least 6 months. Among these, 1–2% develop a strong emotive reaction, anxiety, and depression, leading to poor quality of life. Objectives: to evaluate the comorbidities in tinnitus sufferers. Methods: In our retrospective study, we collected data on 1156 subjects with tinnitus present for at least 3 months, including age, audiometric exam, THI questionnaire, vascular disorders, fluctuations, causal factors, lifetime psychiatric disorders, and the presence of migraine. A linear regression model was used to assess the independent role of these variables on the THI total score representing tinnitus annoyance. A lifetime history of psychiatric disorders and migraine were predictive for the development of a disabling tinnitus. Results: Among comorbidities a history of previous psychiatric disorders was predictive for developing tinnitus. Moreover, no correlation has been found between hearing level and THI total score. Conclusions: Our data are not inconsistent with the hypothesis that psychological disorders and a particular personality trait may be the main causal factors for tinnitus annoyance.

A new species of Ceratomyxa (Ceratomyxidae, Myxosporea) was found infecting the gall bladder of the Argentine croaker Umbrina canosai Berg 1895 (Sciaenidae, Perciformes) from the Argentine sea. Using an integrative taxonomic approach that combines morphological, bioecological, and molecular analyses, we provide evidence that clearly differentiates this species from known taxa and formally describe Ceratomyxa fialai as a new species. This study is the first to apply landmark-based geometric morphometrics (GM) in myxozoan research, providing a detailed analysis of conspecific morphometric variation of ceratomyxid myxospores, examining their natural variation within and among different ceratomyxids infecting the gall bladder of U. canosai. Using GM analyses, we successfully capture and quantify phenotypic variation at the organismal level. Our results suggest that myxospore shape variation may be driven by both developmental noise and phenotypic plasticity. The work highlights the utility of GM in advancing the understanding of myxozoan morphology and its evolutionary implications and emphasizes the need for further research on myxospore shape evolution and its ecological and adaptive significance in natural populations.

As global demand for sheep products increases, improving reproductive efficiency and lamb growth performance has become a priority for sheep farmers. Artificial insemination (AI) offers several advantages over natural mating, including improved genetic selection and disease control. This study contributes to understanding the impact of different mating methods and semen preservation techniques on reproductive performance and growth traits in Palestinian Assaf sheep under local breeding conditions. The research included 123 adult Assaf ewes from two farms, which were hormonally synchronized and divided into three groups for different reproductive biotechnologies. Group 1 (G1) comprised 50 ewes inseminated with frozen semen straws, while Group 2 (G2) had 37 ewes inseminated with fresh semen from genetically superior rams. Both G1 and G2 used 0.5 mL straws containing 250 million sperm, with insemination occurring 48 h post sponge removal and eCG hormone injection. Group 3 (G3) consisted of 36 ewes that underwent natural mating at a ratio of 1 ram to 6 ewes. The study revealed that insemination methods significantly affected fertility rates (45.4, 61.1, and 71.9% for G1, G2, and G3, respectively; p < 0.05). Artificial insemination notably enhanced lamb performance indicators (p < 0.05), although it did not significantly influence prolific lambing (p > 0.05). Prolific lambing significantly impacted birth weight, weaning weight, and average daily gain at 60 days across all groups (p < 0.05), but not the average daily gain or final weight at 180 days (p > 0.05). The management system significantly affected birth and weaning weights at 60 days (p < 0.05), but not the final weight at 180 days or prolific lambing (p > 0.05). Lamb sex significantly influenced average daily gains at 60 and 180 days, as well as final weight at 180 days (p < 0.05). The findings suggest that, while artificial insemination with semen from elite rams may reduce fertility rates, it significantly improves lamb performance rates. In conclusion, our study demonstrates that, while natural mating offers higher fertility rates, AI with fresh semen can be a valuable tool for improving lamb growth performance in Palestinian Assaf sheep. These findings provide valuable insights for sheep farmers in the region to optimize reproductive strategies and enhance lamb production
