The structure of Nd$_{1-x}$Pb$_{x}$MnO$_{3}$ crystals is determined by single crystal X-ray diffraction. Substitution of Pb at the Nd site results
Grazing incidence anomalous x-ray scattering was used to monitor in situ the molecular beam epitaxy growth of GaN/AlN quantum dots
The High Energy Transmission Grating (HETG) Spectrometer aboard the Chandra X-Ray Observatory was used to observe E0102-72, a ~1000 year
We have studied the spectral evolution of stellar populations in function of their heavy element content and star formation, using
We present results on mid-IR (5--16micron) spectral imaging of a sequence of interacting galaxies, observed by ISOCAM. The galaxies are
In the current most plausible Cold Dark Matter (CDM) cosmology, larger clumps increase their mass by the progressive merger of
The radio spectral index map of the Coma halo shows a progressive steepening of the spectral index with increasing radius.
We describe the nature of the interference challenges facing radio astronomy in the next decade. These challenges will not be
Room temperature powder x-ray diffraction measurements have been carried out on polycrystalline samples of CuxV2O5 with x = 0.33, 0.40,
The progressive mixing and contamination of interstellar gas by supernovae and other processes following the passage of a spiral density
In this paper we examine the effective interactions introduced between the droplets of an oil in water microemulsion upon progressive
We present new VLA and Effelsberg observations of the radio galaxy 8C0821+695. We have obtained detailed images in total intensity
We present mid-infrared (5--16micron) images and spectra of a sequence of interacting galaxies, observed by ISOCAM. The galaxies were selected
In this paper we revisit the Mackey-Glass model for blood-forming process, which was proposed to describe the spontaneous fluctuations of
We investigate the optical conductivity of half-filled N-leg Hubbard ladders far into the ``deconfinement'' limit (i.e., weak Hubbard interaction and
The main characteristics of a wide photometric survey of the Sgr dwarf spheroidal galaxy are shortly presented. V and I
We present a model of globular cluster self-enrichment. In the protogalaxy, cold and dense clouds embedded in the hot protogalactic
Any economic agent constituting the monetary economy maintains the activity of monetary flow equilibration for fulfilling the condition of monetary
A simple model of cuprate superconductivity with an electron spectrum prepared by doping is developed. The pair-transfer interaction couples the
We report high-resolution measurements of voltage (V) noise in the mixed state of micrometre-sized thin films of amorphous Nb0.7Ge0.3, which
Using the B-I color index in the radial photometry of M51, applied to defined azimuthal sectors, we reveals asymmetries in
We have used ROSAT PSPC and HRI to study the properties of the soft X-ray emission in a sample of
