Preservative function

Not every linear-subspace-preserving function on projective space descends from a complex linear operator. However, when we consider the unitary structure in Section 10.3 we find an imperfect but still useful converse — see Proposition 10.9. 

In nature, to preserve function a strong selective pressure may act on the secondary structure of functional RNA molecules, while the sequences diverge. This effect...

Comparison of clinical studies using bone marrow and blood-derived cells after acute myocordian infarction to prevent the development of heart failure. Currently, bone marrow-derived stem cells show greater potential to treat early-stage disease, primarily owing to their angiogenic potential, leading to improved left ventricle protection and ultimately to better preserved function. 

The use of techniques that focus on a subset of resonances make it possible to do productive NMR experiments on systems that do not have the narrowest possible linewidths, and thus to investigate more challenging proteins or to optimize sample conditions for a particular functional state rather than for the narrowest resonances. However, since the information content of the NMR experiment depends on the number of resolvable resonances, which depends on their linewidths, it is critical to seek conditions that minimize the linewidths while preserving functionality. The membrane protein system of interest will dictate which sample types are possible and which conditions preserve functionality Table 1 documents membrane protein linewidths that have been observed in a variety of sample types including nanocrystals, 2D crystals, detergent micelles, proteoliposomes and nanodisks. 

As far as the biocide properties are concerned, 0-Mannich bases containing extended hydrocarbon chains and used for their combined detcrgent/gcrmicidc action are worth mentioning. A good preserving function is also performed by plywood adhesives, based on urea, melamine, and formaldehyde, which are fixed by suitable iodo-derivatives presumably by amino- and amidomethylation reactions.

In widely metastatic follicular carcinomas with relatively well-preserved function, sufficient thyroid hormone can he synthesized and secreted to produce thyrotoxicosis. In most instances, a previous diagnosis of thyroid mahgnancy has been made. The diagnosis can be confirmed by whole-body scanning. Treatment with I is generally effective at ablating functioning thyroid metastases. 

Recall from Chap. 5 that, as the dynamics automatically preserves functions of H, the Liouvillian satisfies Ccp(H) = 0. We also know that for Hamiltonian dynamics is skew-adjoint, i.e., = — which implies that = 0. Hence any... 

Let us see what this means in practice. Well preserved functional fluids — metalworking fluids, for instance — can be used longer than unpreserved fluids...
