Microstructural changes in strawberry after freezing and thawing processes
(Elsevier Science, 2005-12)
The selection of freezing conditions is very important in order to optimize the efficiency of the freezing process and simultaneously retain the biological microstructure. Fresh strawberry and osmotically dehydrated ...
Pink grapefruit lycopene encapsulated in alginate-based beads: stability towards freezing and drying
(Wiley Blackwell Publishing, Inc, 2019-02)
Alginate-based beads containing lycopene extract were produced with the addition of various sugars and biopolymers. In present work, lycopene stability was studied on beads subjected to thermal treatments: continuous ...
Mathematical prediction of freezing times of bovine semen straws placed in static vapor over liquid nitrogen
(Academic Press Inc Elsevier Science, 2013-02)
A widespread practice in cryopreservation is to freeze spermatozoa by suspending the straws in stagnant nitrogen vapor over liquid nitrogen (N2V/LN2) for variable periods of time before plunging into liquid nitrogen (-196 ...
Evaluation of temperature effect on the dynamic parameters of a simply supported bridge Laboratory experiments and numerical models = Evaluación del efecto de la temperatura en los parámetros dinámicos de un puente simplemente apoyado : experimentos de laboratorio y modelos numéricos
(Universidad de Concepción.Departamento de Ingeniería CivilDepartamento de Ingeniería Civil., 2016)
We are interested in the effect of freezing and non-freezing temperature distributions on the dymamic parameters of a simply supported bridge. A laboratory scale model is placed on a climate chamber, where a uniform variation ...
The effect of the annealing on the poly(vinyl alcohol) obtained by freezing-thawing
(Elsevier Science, 2011-07-30)
In the present work poly(vinyl alcohol) (PVA) hydrogels were obtained by freezing/thawing technique. The effect of thermal treatment on its performance was studied by annealing the hydrogels at five different temperatures, ...
Decoupled evolution of foliar freezing resistance, temperature niche and morphological leaf traits in Chilean Myrceugenia
(British Ecological Society, 2014)
1. Phylogenetic conservatism of tolerance to freezing temperatures has been cited to explain the tendency
of plant lineages to grow in similar climates. However, there is little information about
whether or not freezing ...
Sublimation conditions as critical factors during freeze-dried probiotic powder production
(Drying Technology, 2019-03-04)
The aim was to study the effect of sublimation temperature (from –20 C to –10 C) and
sublimation time (from 18 to 40 h) on the viability of Lactobacillus fermentum K73, the moisture content and the texture features by ...
Freezing resistance in Patagonian woody shrubs: the role of cell wall elasticity and stem vessel size
(Oxford University Press, 2016-03)
Freezing resistance through avoidance or tolerance of extracellular ice nucleation is important for plant survival in habitats with frequent subzero temperatures. However, the role of cell walls in leaf freezing resistance ...
