Quality attributes of a fermented whey-based beverage enriched with milk and a probiotic strain
(Royal Society of Chemistry, 2014)
Beverages produced by fermentation of whey have significantly lower viscosity, milder flavour and less viability of probiotic microorganisms compared to those obtained by fermentation of milk. Therefore, it is necessary ...
Modeling of the Mechanical Behavior of Fiber-Reinforced Ceramic Composites Using Finite Element Method (FEM)
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Modeling of the mechanical behavior of fiber-reinforced ceramic matrix composites (CMC) is presented by the example of Al2O3 fibers in an alumina based matrix. The starting point of the modeling is a substructure (elementary ...
