The chromophore of C-phycocyanin, phycocyanobilin, was cleaved from the protein with methanol, concentrated hydrochloric acid, or subtilisin BPN’. The pigments obtained were converted to their dimethyl esters and purified by preparative high pressure liquid chromatography and examined for purity by analytical high pressure liquid chromatography on silica gel. They were characterized by proton t...

Original scientific paper The results of numerical experiments on dynamic response of a steel column, with a concentrated mass on the top are presented. The column is fixed in the base subjected to a triangular pulse force. Preisach hysteresis model was applied to investigate the dynamic behaviour of the steel column. In the solution of the non-linear dynamic equation of the motion the fix-poin...

We present a multi-scale molecular modeling of concentrated solutions of unknotted and non-concatenated ring polymers under good solvent conditions. The approach is based on a multi-blob representation of each ring polymer, which is capable of overcoming the shortcomings of single-blob approaches that lose their validity at concentrations exceeding the overlap density of the solution [A. Narros...

Prominent explanations of the overrepresentation of Black Americans in criminal justice statistics focus on the effects of neighborhood concentrated disadvantage, racial isolation, and social disorganization. We suggest that perceived personal discrimination is an important but frequently neglected complement to these factors. We test this hypothesis with longitudinal data on involvement in gen...

We demonstrate a strong correlation between supermassive black hole (SMBH) mass and the global structure of ellipticals and bulges: more centrally concentrated bulges and ellipticals (higher Sérsic index n) host higher-mass black holes. This correlation is as good as that previously found between SMBH mass and central velocity dispersion, with comparable scatter. In addition, by carefully model...

We have used extensive V , I photometry (down to V = 20.9) of 33615 stars in the direction of the globular cluster M 55 to study the dynamical interaction of this cluster with the tidal fields of the Galaxy. An entire quadrant of the cluster has been covered, out to ' 1.5 times the tidal radius. A CMD down to about 4 magnitudes below the turn-off is presented and analysed. A large population of...

We consider an elastic system containing a small region where the density is very much higher then elsewhere. Such system possesses two types of eigenvibrations, which are local and global vibrations. Complete asymptotic expansions of global eigenvibrations for ordinary differential operator of the fourth order are constructed using WKB – technique.

[1] Repeat satellite laser altimetry is critical for observing the rapidly changing mass balance of the Greenland Ice Sheet. However, sparse sampling and high surface slopes over rapidly thinning, coastal outlet glaciers may result in underestimation of mass loss. Here we supplement ICESatderived surface elevation changes with differenced ASTER digital elevation models of outlet glaciers in sou...

The present investigation deals with the deformation in micropolar generalized thermoelastic medium with mass diffusion subjected to thermo mechanical loading due to thermal laser pulse. Laplace and Fourier transform technique is used to solve the problem. Concentrated normal force and thermal source are taken to illustrate the utility of approach. The closed form expressions of normal stress, ...

We present a complete relativistic analysis for the scalar radiation emitted by a particle in circular orbit around a Schwarzschild-antide Sitter black hole. If the black hole is large, then the radiation is concentrated in narrow angleshigh multipolar distributioni.e., the radiation is synchrotronic. However, small black holes exhibit a totally different behavior: in the small black hole regim...
