Thermokinetic, Thermodynamic, and Pyrolysis Analysis of Agro-Industrial Biomass for Bioenergy: Insights from Isoconversional Models and Neural Networks

Abstract The growing demand for renewable energy and sustainable waste management has driven interest in the thermochemical valorization of agro-industrial residues. This study investigated the thermokinetic, thermodynamic, and pyrolysis behavior of four lignocellulosic biomasses...

A Blockchain-Enabled Indoor Navigation Framework Integrating Beacon Technology for Accessibility and Traceability

Abstract This article presents a computational framework integrating beacon and Blockchain technologies to develop a secure and accessible indoor navigation system for individuals with visual impairments. The proposed solution defines a flexible and extensible architecture that s...

Sexual dimorphism of the human calcaneus: a cross-sectional morphometric study

Sex estimation from skeletal remains is a fundamental step in forensic anthropology. The calcaneus, the largest tarsal bone, is robust and may serve as an alternative indicator when the skull and pelvis are unavailable. This study evaluated sexual dimorphism in the calcaneus of a...

Coding for sustainability? Investigating how sustainable practices emerge in software development

Abstract This study investigates the adoption of sustainable practices in software development through a mixed-method approach that integrates quantitative and qualitative analyses. Grounded in the best practices proposed by the Green Software Foundation (GSF), a research instrum...

Dynamic collapse initiation and propagation in submarine pipelines: A fluid–structure interaction study

The dynamic propagation of collapse in submarine pipelines is strongly influenced by fluid–structure interaction (FSI), yet its quantitative effects remain insufficiently characterized. This study investigates the role of the surrounding fluid on collapse propagation dynamics thr...

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...
