Tetracyclic naphthoquinone-carbohydrate conjugates with an angular-fused heterocycle were obtained for the first time by the intramolecular condensation of naphthazarin thioglucosides in a mixture of n-butanol and methanesulfonic acid under reflux. T

Electrospray ionization mass spectra and collision-induced dissociation mass spectra in positive and negative ion modes of five polyhydroxysteroid compounds from starfish were studied. Tandem mass spectra exhibit extensive fragmentation, including se

Crystallization of thin films of amorphous hydrogenated silicon under the irradiation of femtosecond laser pulses has been studied. It was found that the crystallization has a clearly pronounced threshold nature and depends on the laser emission wave

Propagation of elastic waves in a system of cylindrical channels embedded in a homogeneous isotropic elastic medium (a phononic crystal) is investigated. A multipole method is proposed for simulation of wave propagation in such structures. The disper

1. Nowadays, advances of activity in fundamental science representing the basis of the pioneering technology and also in commerce (a small-scale and largescale business), etc. depend principally on the possibility and ability of gaining and properly

Two ways of modeling of elastic wave propagation in microstructured acoustic fiber are considered. First one is the calculation of band gap parameters by FEM for phononic crystal forming cross section of fiber. Second one is immediate calculation of
