Wood products, particularly whole, unprocessed logs, are a significant risk pathway for forest insect pests. Freshly harvested logs continue to respire, creating a high carbon dioxide (CO2), and low oxygen (O2) atmosphere in enclosed spaces. Such modified atmospheres may reduce the effectiveness of insect control treatments applied during the transit of logs, making it important to accurately quantify

Coffee is an important agricultural commodity worldwide. Its quality is influenced by several factors that can damage kernels, changing the product composition, flavor, appearance, and causing weight loss. Mathematical models for estimating the dry matter loss of coffee were not found in scientific literature.
