The effective elastic properties of human trabecular bone may be approximated using micro-finite element analyses of embedded volume elements.
PublikacjaBoundary conditions (BCs) and sample size affect the measured elastic properties of cancellous bone. Samples too small to be representative appear stiffer under kinematic uniform BCs (KUBCs) than under periodicity-compatible mixed uniform BCs (PMUBCs). To avoid those effects, we propose to determine the effective properties of trabecular bone using an embedded configuration. Cubic samples of various sizes (2.63, 5.29, 7.96, 10.58...

Relationship between the betalain composition in Opuntia ficus indica and Beta vulgaris varieties and biological activity of their extracts
PublikacjaBetalains are a class of pigments that are much less com- monly found in nature than anthocyanins or carotenoids. They occur only in a few edible plants such as red beetroot (Beta vulgaris), prickly pears (Opuntia ficus indica), amaranth (Amaranthus sp.) and some mushrooms. This group of pig- ments can be divided into two major groups: yellow vulgax- anthins and red betanins. Despite their structural similarity to compounds from...
