Adhesion between geopolymer matrix and vegetable fibers: effect of matrix composition and fiber treatment

Seeking to promote sustainable composites composed of a low-carbon matrix and a renewable reinforcement, this study evaluated the fiber–matrix adhesion of sisal fibers used as reinforcement in geopolymeric matrices produced by the alkaline activation of fiber cement waste, in com...

Fuzzy hybrid system based on ensemble learning for classification in intelligent manufacturing processes

Abstract The integration of Machine Learning (ML) into advanced manufacturing is a key enabler of Industry 4.0, supporting intelligent quality control and early fault detection. Despite recent advances, challenges remain regarding the interpretability and adaptability of multicla...

Between Leaves, Prayers, and Healing Hands: A Cross-Regional Scoping Review of Ritual Healers and Plant-Based Community Knowledge

Plant-based healing practices integrate botanical resources, ritual speech, gesture, faith, spiritual mediation, protection, and social recognition within complex community systems of care. This cross-regional scoping review mapped the traceable literature on plant-based knowledg...

Skew-symmetric augmented matrices and a characterization of virtual doodles

Abstract In this paper, we present a brief overview of the concept of doodles from the perspective of J. S. Carter’s work on classifying immersed curves and the work of J. Carter, S. Kamada, and M. Saito on stable equivalence of knots on surfaces and virtual knot cobordisms. We u...

Terminology in para sport research: is there a “correct” way to speak about disability?

Language used in disability sport reflects societal values and shapes how athletes are perceived. In adapted, Para, and Paralympic contexts, terms are not merely descriptive – they influence identity, inclusion, and respect. Two main approaches are discussed: person-first languag...

Microparticles of greenish-brown propolis extract: phytochemical, physicochemical characterisation and in vitro dissolution profile

The low solubility of propolis in water and its limited bioavailability reduce the effectiveness of bioactive compounds, demonstrating the necessity of techniques that can overcome these limitations. Spray-drying is a promising approach to overcoming these challenges. In this stu...

Rethinking Plasticity in Sponges

What lies behind the extraordinary phenotypic plasticity of sponges? We used this question to conduct a systematic review of how "phenotypic plasticity" is approached in the literature regarding the phylum Porifera. First, we gathered information on what the literature says about...

Effect of Combined Aerobic and Resistance Training on Exercise Capacity, Muscle Strength, Quality of Life, and Mortality in Patients with Coronary Heart Disease: A Systematic Review with Meta-analysis

CART (combined aerobic and resistance training) has shown important results in exercise-based cardiovascular rehabilitation. However, there are little data concerning the effects of CART on the exercise capacity, muscle strength, health-related quality of life (HRQoL), and mortal...

Tropical-Forest Degradation–Restoration Interface: A Comprehensive Review

Tropical forests sustain exceptional biodiversity and regulate global carbon and water cycles, yet degradation and incomplete recovery increasingly compromise these functions. We integrated bibliometric mapping with structured systematic synthesis to characterize research at the...
