5. Fluoroquinolones in industrial poultry production, bacterial resistance and food residues:a review
Fluoroquinolones are antimicrobial agents frequently used in poultry production and in human medicine. The use of such substances must comply with safety criteria, including withdrawal periods, doses, and treatment duration, as their misuse and abuse may cause bacterial resistance and the presence of residues in edible tissues. Consequently, the consumption

11. Projeto industrial para aeração automática de leiras de compostagem orgânica / Industrial project for automated aeretion of organic composting piles
Composting is a safety environmental alternative to reuse and treat organic wastes produced by human-beings. Although decomposition naturally happens, the handling of some factors, such as oxygen level, temperature, moisture content and pH, can alter the process speed, accelerating microbial activity. Aeration is a crucial practice during the composting proc
