FARMER PERCEPTIONS RELATED TO POTATO PRODUCTION AND LATE BLIGHT MANAGEMENT IN TWO COMMUNITIES IN THE PERUVIAN ANDES

Farmer Perceptions Related to Potato Production and Late Blight Management in Two Communities in the Peruvian Andes

Potato late blight (LB), caused by the oomycete, Phytophthora infestans, continues to be a major constraint of potato in the Andean region and worldwide.Farmers perception regarding potato production with particular emphasis on management practices for LB was surveyed in two communities in the Peruvian highlands using a questionnaire with 25 questi

Theoretical and Numerical Investigation of Reduction of Viscous Friction in Circular and Non-Circular Journal Bearings Using Active Lubrication

Reducing friction losses is one of the most common ways to improve fluid film bearings, whose adjustable design provides additional opportunities to improve their dynamic and tribological properties.Previous studies have shown the possibility of reducing viscous friction in actively lubricated bearings by adjusting the rotor position.This work prov
