Microbiological safety in the reuse of materials in home enteral nutrition: A quantitative in vitro experimental study

Nutrition in Clinical Practice, EarlyView.
Abstract Introduction In home enteral nutrition (HEN), the reuse of packaging and administration materials beyond the recommended period, combined with inadequate hygiene practice, increase the risk of microbiological contamination. This study assessed the risk through a simulation that reproduced real‐world usage conditions and hygiene practices ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Modelling bacteriological water quality in drinking water distribution systems

Water Science and Technology, 1998
Because on-site experimentation raises numerous problems, the study and the modelling of bacterial regrowth phenomena in drinking water distribution systems has been performed using a pipe loop pilot under various operating conditions. As a result, experiments have shown that inlet bacterial counts have little influence on the biofilm behavior which is
