Modeling of drying kinetics and chemical analysis for optimal preservation of pitahaya, aguaymanto and pineapple fruits using a parabolic solar dehydrator in the Amazon region - Pe...
Published 2025-03-01“…In this research, the drying kinetics were modeled, and a chemical analysis was performed to determine the optimum preservation conditions for pitahaya (Selenicereus undatus), aguaymanto (Physalis peruviana), and pineapple (Ananas comosus) fruits using a parabolic solar dehydrator in the Amazon region of Peru. Five mathematical models were used to determine the drying curve, with the criterion of selection the best model with the coefficient of determination (R2) and model efficiency (EF); in addition, pH and titratable acidity were evaluated during the dehydration period. …”

First evidence of transovarial transmission of Kyasanur Forest disease virus in Haemaphysalis and Rhipicephalus ticks in the wild
Published 2025-01-01“…Empirical data on pathogen-vector-host interactions and incrimination have not been updated since the last century, despite significant local changes in land use and the expansion of KFD to new areas. Mathematical models predict that transovarial transmission, whereby adult female ticks pass KFDV infections to their offspring, plays an important role in the persistence of KFD, but this has not been shown in the wild. …”
