Isochoric (constant volume) preservation is an alternative to traditional cryopreservation methods because it requires less cryoprotectant and is simple to operate.
In the initial stages of early IVD degeneration (classified as the mixed group), Brachyury and Cytokeratin 8 gene expression remained constant, indicating the preservation of the NC phenotype in the NP at this stage in both chondrodystrophic and non-chondrodystrophic dogs.
First, RGB space is mapped to hue-saturation-intensity (HSI) space and the hue component remains constant through a hue preservation principle.
The tiger had no destination, only the constant tug of self-preservation in the pit of his stomach, some vague, inborn sense of what he was looking for, which carried him onward.
We incorporate adaptive time-stepping within the present scheme and this in turn enables still higher accuracy and a 'near preservation' of constants of motion over significantly longer intervals.
The preservation of these constant structural functional features throughout such a long phylogenetic span likely points to the successful gain-of-function conferred by their early acquisition.
The coupling method also exhibits consistency properties, such as conservation of uniform movement of both fluid and solid, absence of numerical roughness on a straight boundary, and preservation of a constant fluid state around a wall having tangential deformation velocity.
This endocytic mechanism might support the sustained expression of uPAR at its functional sites as well as ensuring the preservation of a constant membrane area.
In this coevolutionary arms race scenario, continually evolving host resistance would give rise to constant selective pressure for the preservation of duplications of genes relevant to virulence [ 20, 42, 43].
Since the paintings were discovered by four teenagers (and a dog) in September 1940, however, their preservation has been a constant headache, with government officials in Paris and the local authorities criticized for failing to ensure their proper protection.
