Determination of the Isotopic and Elemental Composition of the Core of an Armor-Piercing Projectile

The elemental and isotopic composition of the core material of a hard-core projectile that had fallen onto the ground was studied by secondary-ion mass spectrometry, alpha and gamma spectrometry, X-ray photoelectron spectroscopy, and scanning electron microscopy with X-ray microanalysis. The environmental aspect of the use of depleted uranium ammunition in Yugoslavia is discussed.     

On the residual finiteness of generalized free products of finite rank groups

We find necessary and sufficient conditions for the residual finiteness of some free products of finite rank groups with amalgamated subgroups.     

Parametric Model of the Optical Constant Spectra of Hg1 – xCdxTe and Determination of the Compound Composition

Optics and Spectroscopy - A parametric model describing the spectra of optical constants n(λ) and k(λ) of a Hg1 – xCdxTe (MCT) solid solution for the x values in...     

On the residual finiteness of the HNN-extensions and generalized free products of finite rank groups

We obtain necessary and sufficient conditions for the residual finiteness for some HNN-extensions and generalized free products of soluble minimax groups.
