    Published 2022
    “…As a result, small-scale production of cassava starch and HQCF often incurs high production costs, incompatible with market prices of fnal products. Taking stock of this situation, RTB scientists have developed several innovations to optimize energy effciency and costs, including a longer drying pipe, reengineered heat exchanger, larger blower for higher air velocity, and a higher product/air ratio. …”

  6. The pathway to genetic gains in Ethiopian dairy Cattle: Lessons learned from African Dairy Genetic Gains Program and tips to ensure sustainability by Meseret, Selam, Gebreyohanes, Gebregziabher, Mrode, Raphael A., Ojango, Julie M.K., Chinyere, Ekine, Hassen, A., Tera, Asrat, Jufar, B., Kahumbu, S., Negussie, E., Okeyo Mwai, Ally

    Published 2022
    “…The great achievement has been realized due to existence of systematic animal identification and consistent performance recording, both of which are crucial for sustained national genetic evaluation, identification, and use of genetically superior and locally adapted dairy breeding stock. Furthermore, identifying roles and responsibilities, and strengthening collaboration among key dairy actors and strong government leadership and support are mandatory to build sustainable breeding program.…”

  8. Driving factors of tree biomass and soil carbon pool in xerophytic forests of northeastern Argentina by Sione, Silvana María José, Wilson, Marcelo German, Ledesma, Silvia Gabriela, Gabioud, Emmanuel Adrian, Oszust, José Daniel, Rosenberger, Leandro Javier

    Published 2024
    “…The vertisols showed a 27.8% higher soil carbon stock than alfisols. Conclusions: The relevance of our study stems from a dearth of information on carbon pools and their drivers in xerophytic forests, and in particular, the importance of this ecosystems’ type for Argentina, because they cover 81.9% of native forest area. …”
