Films incorporated with essential oils had higher transparency values than the control film, regardless of essential oil types (p < 0.05).
No working model was ever built, but Barber's sketches and the low efficiency of the components available at the time make it clear that the device could not have worked even though it incorporated the essential components of today's gas-turbine engine.
Films incorporated with essential oils had the marked increase in antioxidative activities and chelating activity (p < 0.05).
Amongst all film samples, that incorporated with plai essential oil had the highest of b*- and ∆E*-values with the lowest L*-value and WI (p < 0.05).
Amongst all films, that incorporated with plai essential oil showed the highest b*- and ∆E*-values but lowest WI (p < 0.05).
These examples serve to show how real problems almost always demand the invention of models in which, it is hoped, the most important features are correctly incorporated while less-essential features are initially ignored and allowed for later if experiment shows their influence not to be negligible.
Amongst all essential oils incorporated, basil essential oil had the highest efficiency in lowering WVP of film (p < 0.05), followed by lemon and plai essential oils, respectively.
Amongst all essential oils incorporated, basil essential oil yielded the film with the highest TS and EM (p < 0.05), followed by those containing plai and lemon essential oils, respectively.
Light transmission of visible range (350 800 nm) of film without essential oil incorporated (control) ranged from 42.84 to 89.12 %, whereas lower values were observed for film incorporated with essential oils (6.13 80.38 %), regardless of essential oil types.
Two composite outcome measures were chosen that incorporated most of the essential components as outcome measures for a brief intervention.
