According to the conservation of the first adiabatic invariant, the local pitch angle (alpha) along the geomagnetic line satisfies sin alpha = sin alpha_{text{eq}} left[ {fleft( lambda right)} right]^{1/2}.
Downstream of the resonance region the perpendicular velocity boost should be converted to axial flow velocity through the conservation of the first adiabatic invariant as the magnetic field decreases in the exhaust region of the VASIMR.
If we consider the distribution of changes along the E1-E2 regitn, is is remarkable the high degree of conservation of the first 56 amino acids, which correspond to the C-terminus of the envelope 1 protein (Table 3 and Figure 4).
The data presented here constitute the first comprehensive saturation mutagenesis analysis of a metallohydrolase active site and reveal that the strict conservation of the second-shell metal binding residues in eukaryotic arginases does not reflect kinetic optimization of the enzyme during the course of evolution.
Conservation of the first three amino acids further confirmed the likely start codon.
Most strikingly, the alignment highlighted the universal conservation of the first leucine residue in the V regions of all animals.
COX-3 is a recently described derivative of COX-1 that occurs as the result of conservation of the first intron and is also called COX-1 V1.
As the 'module membership' is closely related to the first eigenarray of each cluster, their findings imply conservation of the first eigenarrays between the corresponding clusters.
As suggested by Fedorova and Fedorov [ 28], conservation of the first intron at the 5'end of many genes also appears to be under stringent functional constraints.
Extremities in subgroups IS 4Sa and IS 4 displayed relaxed conservation of the third and first nucleotide, respectively, which is rather new but not unique in family IS 4 (see below).
The library of D124 and W122 showed absolute conservation of the first-shell D124 residue, and only a few amino acids were observed to substitute for W122, resulting in greatly reduced activity (Table S3 of the Supporting Information).
