Hospitality organisations are crucial in driving green and sustainable business practices as the world advances toward global decarbonisation. This study investigates the relationship between Green Leadership Behavior (GLB) and employee Environmental Citizenship Behavior (ECB), focusing on the mediating role of three facets of Green Intellectual Capital (GIC), i.e. Green Human Capital (GHC), Green Structural Capital (GSC) and Green Relational Capital (GRC). The study is based on a multilevel dataset comprising 264 employees (Level 1) nested within 16 hospitality organisations (Level 2). We used a 2-1-1 multilevel mediation model to analyse the data, using Jamovi 2.5 software. We found that GHC, GSC, and GRC serve as a mechanism through which GLB is associated with increased ECB. The study recommends valuable insights for hospitality organisations to provide the necessary and timely availability of intangible assets such as GHC, GSC, and GRC so that GLB may effectively exploit GIC to encourage ECB. We contribute to the leadership literature in tourism and hospitality by identifying key pathways through which GLB influences ECB, emphasising the crucial role of GIC in shaping employees’ environmentally friendly behaviors.

Herein, 40 growing male lambs of the Al-Naimi breed were randomly divided into 4 groups and fed a single diet with four particle sizes and lengths of alfalfa forage (1, 5, 10, or 15 mm) in a pelleted complete diet (PCD); lambs were housed individually for 14 weeks. Compared with lambs in the control group, lambs fed either SLF10 or SLF15 diets exhibited increased slaughter weight, carcass weights (hot and cold), and the percentage of liver, heart, and trimmings ( P < 0.05), whereas they exhibited reduced thickness of back and body wall fats ( P < 0.05). Furthermore, the water-holding capacity and springiness of meat were the greatest ( P < 0.05) in the control group lambs (SLF1). Additionally, the nutritional indices showed a significant improvement; the thrombogenicity index corresponding to the palmitic acid C16:0 content was higher in the SLF1 group than in other groups ( P < 0.01). Therefore, a particle size of alfalfa of 10–15 mm in PCD improved carcass characteristics and meat quality in growing lambs without compromising the FA profile and indicators of healthy nutrition.

The Egyptian irrigation system considers barrage regulators important structures for controlling flow discharge and upstream/downstream water levels. This study presents an experimental model simulating flow across radial gates, focusing on how symmetric and asymmetric gate operation schemes influence hydraulic behavior. A total of 80 test runs were performed using five gate-operating schemes under 16 flow conditions, including four tailwater depths (0.21, 0.23, 0.25, and 0.27 m) and four discharges (26, 29, 32, and 35 L/s), while maintaining a constant upstream depth of 0.40 m. Results showed good agreement between measured and calculated discharge coefficients compared with previous studies. Gate operation symmetry, under similar expansion ratios, had minimal effect on the discharge coefficient. The contraction coefficient was inversely related to the gate leaf angle. The length of the hydraulic jump increased with the increase in the Froude number. The outcomes gave good agreement compared to other formulas under similar hydraulic conditions. The submergence ratio increased with the increase in the submerged hydraulic jump length. A regression analysis model was applied, and simple empirical equations were derived to predict the discharge coefficient and the hydraulic jump length under limited flow conditions.

Herein, the practicability of the attenuated total reflectance-mid infrared (ATR-MIR) technique combined with chemometrics was reported for the expeditious characterization and discrimination of the papers based on their fiber contents. In accordance with this purpose, twenty-six paper samples ( n = 26 ) with different contents were prepared from three different fiber sources ( long fiber, short fiber, and deinked fiber ), and they were studied using ATR-MIR spectroscopy allied with principal component analysis (PCA), hierarchical clustering analysis (HCA), linear discriminant analysis (LDA), and soft independent modeling of class analogies (SIMCA). The mechanical characteristics [ weight (g), grammage (g.m −2 ), thickness (mm), tensile index (Nm.g −1 ), breaking length (km), moisture absorption (%), brightness (R457), whiteness and yellowness degree (E313) ] of the samples were also determined and evaluated. The spectra were obtained in the wavenumber region of 4000–650 cm −1 and up to 30 wavenumber regions related to the components of papers were analyzed for chemometrics. A total of 100% of paper samples from different groups could be correctly classified by the SIMCA model with an accuracy of 95%. As well, a total of 94.87% of the samples were acceptably classified by the LDA model with an accuracy of 95%. Consequently, the developed chemometrics models based on ATR–MIR data could overcome many problems encountered in routine standard methods for the mechanical characteristics in practice because they decrease or eliminate the usage of destructive methods, could be utilized by unqualified persons, and are significantly faster.

We developed an original computational model for cell deformation and migration capable of accounting for the cell sensitivity to the environment and its appropriate adaptation. This cell model is ultimately intended to be used to address tissue morphogenesis. Hence it has been designed to comply with four requirements: (1) the cell should be able to probe and sense its environment and respond accordingly; (2) the model should be easy to parametrize to adapt to different cell types; (3) the model should be able to extend to 3D cases; (4) simulations should be fast enough to integrate many interacting cells. The simulations carried out focused on two aspects: first, the general behaviour of the cell on a homogeneous substrate, as observed experimentally, for model validation. This enabled us to decipher the mechanisms by which the cell can migrate, highlighting respective influences of the adhesions lifetimes and their sensitivity to traction; second, it predicts the sensitivity of the cell to an anisotropic patterned substrate, in agreement with recently published experiments. The results show that mechanosensors simulated by the model make it possible to reproduce such experiments in terms of migration bias generated by the substrate anisotropy. Here again, the model provides a biomechanical explanation of this phenomenon, depending on cell-matrix interactions and adhesion maturation rate.

Altered eating behaviors may precede the onset of full-scale eating disorders. Given the link between eating disorders and migraine, it is critical to identify individuals with migraine with altered eating behaviors. Therefore, this study aimed to investigate eating behaviors in a sample of migraine patients and to examine their potential associations with migraine frequency and related disability. Adult patients diagnosed with migraine (n = 531) were asked to report their monthly migraine days (MMDs), complete the Headache Impact Test-6 (HIT-6), and answer the Adult Eating Behavior Questionnaire (AEBQ). A group of healthy controls (n = 1062) was also asked to answered AEBQ. Migraine patients had a significantly lower score in the enjoyment of food compared to controls ( P = 0.037), whereas they had significantly higher scores in hunger and satiety responsiveness compared to controls ( P values < 0.001 and 0.008, respectively). There were no statistically significant differences between patients and controls in terms of scores for food fussiness, food responsiveness, emotional overeating, slowness in eating, and emotional undereating. There were statistically significant negative correlations between MMDs and both enjoyment of food and food responsiveness scores ( P = 0.006 and 0.032, respectively). A statistically significant positive correlation was found between HIT-6 total scores and satiety responsiveness scores ( P = 0.002). Altered eating habits are frequently reported among individuals with migraine, adding to the migraine burden. Health professionals, therefore, need to consider these eating behaviors to foster more tailored nutrition interventions for patients with migraine, aiming at improving their quality of life.

Conventional pervious pavements are often constrained by low mechanical strength and insufficient infiltration capacity, limiting their long-term performance and structural reliability. To address these limitations, this study presents a laboratory-scale evaluation of 3D-printed plastic gyroid triply periodic minimal surface (TPMS) porous structures intended for pervious pavement applications. The compressive and flexural strengths, rutting resistance, skid resistance and infiltration rate were assessed following ASTM and AASHTO standards. The results showed that 3D-printed pervious pavement specimens exhibited superior compressive (36.32–37.2 MPa) and flexural (4.74–4.87 MPa) strengths, surpassing those of conventional pervious pavements. Wheel tracking results showed minimal rutting before aging (0.40 mm at 6250 cycles) and moderate increases after aging due to polymer chain degradation. Skid resistance values (78–80 BPN) exceeded the TRRL threshold, ensuring adequate traction, while infiltration rates (6.50–7.43 cm/s) were significantly higher than traditional pervious pavements. This approach effectively addresses the mechanical and hydraulic limitations of conventional pervious pavements. Overall, the proposed concept shows promising a strong potential for future sustainable and high-performance pavement applications by simultaneously improving structural integrity, surface safety and drainage efficiency.

Traditional pavement monitoring systems costing hundreds of thousands of dollars create significant barriers for budget-limited transportation agencies. This research addresses this accessibility gap by developing a complete computer vision framework for automated pavement distress detection and quantification using low-cost embedded systems ($214) combined for affordable data collection with synthetic data augmentation to overcome fundamental class imbalance challenges. The framework employs StyleGAN3-based synthetic data generation with automated quality assessment (94.12% accuracy) and evaluates three integration strategies: direct synthetic augmentation, iterative pseudo-label refinement, and teacher-student transfer learning. Systematic evaluation across eight state-of-the-art architectures (YOLOv9-12, RT-DETRv2, Mask R-CNN variants, RTMDet) reveals that optimal synthetic data ratios vary substantially by architectural design, ranging from 60% to 300% of original dataset size, with transformer-based models showing earlier saturation compared to CNN-based architectures. The methodology integrates advanced image stitching for georeferenced orthomosaic creation and automated distress quantification. Comprehensive validation across twelve road segments (7.15 miles) demonstrated substantial performance improvements up to 12.3 percentage points in [email protected]:0.95, with direct augmentation proving most effective (0.896 [email protected] detection, 0.905 segmentation). A complete deployment package including CPU-based graphical user interface and GIS integration enables practical implementation for transportation agencies, providing accessible state-of-the-art pavement monitoring capabilities without requiring specialized computational infrastructure or technical expertise.

The interaction of N,N-disubstituted benzimidazolium salts 2a–e with Ag 2 O formed new silver-(N-heterocyclic carbene) complexes 3a–e. Structural characterization of silver-(N-heterocyclic carbene) complexes was conducted by using NMR, FT-IR and elemental analysis. Preliminary catalytic studies using all the silver complexes 3a–e were performed on three-component coupling reaction of a series of aldehydes with alkynes and amines was demonstrated. Most of these reactions led to formation of the expected propargylamines in good conversions using low amounts catalyst and obviating both the use of purified reagents as employ of a glovebox. Complexes 3a and 3c exhibited good catalytic activities under neat conditions. The silver complexes 3a–e showed luminescence properties in CH 3 CN at room temperature.

Research Findings : Social competence in early childhood serves as a foundation for later developmental and academic outcomes. Although self-regulation is widely recognized as a key contributor to social competence, previous studies have primarily employed variable-centered approaches to examine the relation between self-regulation and social competence. In the current study, we adopted a person-centered approach to construct self-regulation profiles and examined the relation between these profiles and social competence. A total of 607 children (Mage = 56.89 months, 54% male) participated in the study, in which self-regulation was measured using performance-based assessments and social competence was assessed through teacher-reported measures. Latent profile analysis identified three self-regulation profiles: “optimal self-regulators” (71%), “moderate self-regulators” (12%), and “challenged self-regulators” (17%). The results indicated that children in the optimal self-regulators profile exhibited higher levels of social competence compared to those in the moderate and challenged self-regulator profiles. Practice or Policy : Findings highlight the need for tailoring self-regulation interventions to children’s distinct self-regulation profiles, as a one-size-fits-all approach may be less effective in promoting social competence.
