The configuration of mitiromycin (2) was first determined by NMR experiments including the NOE technique. The absolute structure of 2 was related to mitomycin B (3) because 2 was derived from 3 under basic conditions. The ketonic form 4 was presumed to be involved in the generation of 2.

A unified analytic solution approach to both static bending and free vibration problems of rectangular thin plates is demonstrated in this paper, with focus on the application to corner-supported plates. The solution procedure is based on a novel symplectic superposition method, which transforms the problems into the Hamiltonian system and yields accurate enough results via step-by-step rigorou...

The expressions foavibrational overlap integrals of the one-dimensional harmonic wavefunctions (centenxi about different equilibrium positions and having different frequencies) have been derived in a simple and straightforward way.

We prove that unital-derived ðq qþ 1Þ-arcs of PGð2; qÞ still yield complete arcs after multiple derivation with respect to disjoint derivation sets on a given line.

We give an algorithm of decomposition for a finite-dimensional Lie algebra over a field of characteristic 0 permitting to generalize the derivation tower theorem of Lie algebras.

We introduce the concept of the equiphase sphere for light scattering by nonspherical dielectric particles. This concept facilitates the derivation of a simple analytical expression for the total scattering cross section of such particles. We tested this concept for spheroidal particles and obtained a bound on the minor-to-major axis ratio for the valid application of this technique. We show th...

In this paper we present the quasi-Gaussian entropy theory in a comprehensive and consistent way, introducing a new derivation of the theory very suited for applications to molecular systems, and addressing its use in the case of multi-phase systems. A general derivation of the possible connnement of the system within a part of phase space is given, and for water it is shown that for this a har...

Acousticians generally assess the acoustic qualities of a concert hall or any other room using impulse response-based measures such as the reverberation time, clarity index, and others. These parameters are used to predict perceptual attributes related to the acoustic qualities of the room. Various studies show that these physical measures are not able to predict the related perceptual attribut...

Starting from the problem of two fixed centres we find a simple derivation of its third integral in terms of the scalar product of the angular momenta about the two fixed centres. This is then generalised to find the general form of the potential in which an exact third integral exists.
