Optimal moment to change pressure regulator and sprayer kit on center pivot irrigation machines: application to a study case
(2011-12-01)
A theoretical model developed by the authors for determining the optimal moment to substitute sprayer and pressure regulator kit on a center pivot irrigating potatoes and beans has been applied. The methodology compares ...
Effect of allowable flow-rate variation and local head loss on maximum length of non-pressure compensated drip tapeEfeito da variação de vazão permitida e da perda de carga localizada no comprimento máxima de fita gotejadora não compensada
(2021-01-01)
A challenge for the design of drip irrigation systems with non-pressure compensated emitters is to increase the maximum length of the lateral lines without significantly reducing water application uniformity. This work ...

Preservation of Microstructure in Peach and Mango during High-pressure-shift Freezing
(Wiley Blackwell Publishing, Inc, 2000-04)
A histological technique was used to evaluate modifications on the microstructure of peach and mango due to classical methods of freezing and those produced by high‐pressure‐shift freezing (HPSF). With the high‐pressure‐shift ...
