Magnetic helicity, as a well preserved quantity, in particular in plasma with high magnetic Reynolds number, is a more suitable physical quantity to use, even if reconnection is involved.
Michelangelo's poetry is also preserved in quantity from this time.
The resulting integrator preserves important quantities like the total energy, magnetic helicity and cross helicity exactly (up to machine precision).
This formulation facilitates the design of time integration schemes which preserve mechanical quantities like linear and angular momentum and total energy balance.
However, one can go deeper in the randomization process and preserve more quantities that just the degree of each node.
By taking the volume-preserving methods as the kernel, the processed methods are still volume-preserving, and preserve the conservative quantities for the Lorenz force system.
The water the plant could produce — about 100,000 acre feet per year, enough to supply the needs of a half-million people — would allow Western states to preserve that quantity upriver for their use rather than send it to Mexico, as is done now to fulfill treaty requirements.
C. 450 BCE ancient Greece c. 388 BCE Aristophanes, (born c. 450 bce died c. 388 bce), the greatest representative of ancient Greek comedy and the one whose works have been preserved in greatest quantity.
These macroscopic quantities are preserved in exactly reduced models.
Moreover, by sampling from the joint posterior distributions of the input quantities, we preserved between-municipality correlations in the output so that reliable CrIs for the total number of AD in the region, and by province, could be derived by summing the estimated impacts over municipalities.
IN the heyday of the LP, from 1950 or so to 1980, exclusive contracts with major record labels were the norm for noted musicians, and an entire generation of artists preserved their works in quantity.
