Research ArticleOpen accessIn the abstractImproved Compost Production from Fruit and Vegetable Market Waste: A Case Study in Bagua, Amazonas (Peru)Juan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Wilfredo Ruiz Camacho, Juan Francisco Robles RuizInadequate management of organic solid waste in municipal markets represents a critical environmental challenge in tropical developing regions, where high humidity (>80%) and elevated temperatures (>25°C) accelerate decomposition, generating leachate and greenhouse gas emissions. In Peru, over 50% of municipal waste is organic, yet less than 20% is valorised through composting, highlighting a substantial technological gap. This study evaluated an … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 11 Aug 2026 · 1,262 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMRI Observation and Analysis of Muscle Activity During ExerciseLi-Chang Zou, Hong-Wu LiWhile conventional biomechanical testing techniques are able to determine the mechanical characteristics of muscle tissue, they do not offer precise insight into how muscle metabolism and microstructure change in response to various types of exercise activities over the course of time.
