The growth of series of actual laser crystals belonging to di erent structural types by the Czochralski method is presented. The primary attention is given to single crystalline compounds and their solid solutions with garnet structure (scandium-containing rare-earth garnets with general formula {LnSc}3[ScMe]2Me3O12, Me = Al, Ga) as well as with olivine (forsterite Mg2SiO4) and scheelite struct...

Structural analyses were performed on the intact glycopeptides and on the linkage region oligosaccharide-peptides derived from the keratan sulfate proteoglycan from monkey cornea (Nakazawa, K., Newsome, D.A., Nilsson, B., Hascall, V.C., and Hassell, J.R. (1983) J. Biol. Chem. 258, 6051-6055) using trifluoroacetolysis, Smith degradation, chromium trioxide oxidation, and gas-liquid chromatography...

Given the modeling and predictive abilities of quantitative structure activity relationships (QSARs) for genotoxic carcinogens or mutagens that directly affect DNA, the present research investigates structural alert (SA) intermediate-predicted correlations A(SA) of electrophilic molecular structures with observed carcinogenic potencies in rats (observed activity, A = Log[1/TD(50)], i.e., [Formu...

This paper presents a study of operational and type-theoretic properties of different resolution strategies in Horn clause logic. We distinguish four different kinds of resolution: resolution by unification (SLD-resolution), resolution by term-matching, the recently introduced structural resolution, and partial (or lazy) resolution. We express them all uniformly as abstract reduction systems, w...

Minimality ranks in the style of Deissler are one way of measuring the structural complexity of minimal extensions of first-order structures. In particular, positive Deissler rank measures the complexity of the injective envelope of a module as an extension of that module. In this paper we solve a problem of the second author by showing that certain injective envelopes have the maximum possible...

In a continuation of the structural studies on ribonuclease reported in earlier papers (l-3), the products resulting from the action of pepsin on performic acid-oxidized ribonuclease have been examined by means of ion exchange chromatography. Eight peptides have been isolated in purified form and their amino acid compositions have been determined. In a following communication (4), a partial str...

This paper contributes to the theory of hybrid substructural logics, i.e. weak logics given by a Gentzen-style proof theory in which there are constraints on the application of some structural rules. In particular, we address the question how to add an operator to the Lambek Calculus in order to give it a restricted access to the rule of Permutation, an extension which is partly motivated by li...

Intermetallic compounds with the overall formula Mn1.1Fe0.9P0.5As0.5-xGex (x varies from 0 to 0.1) were investigated in order to study their magnetocaloric effect by monitoring the adiabatic temperature change, magnetic entropy change and their relation to structural parameters. It was found that the maximum of magnetocaloric effect was achieved for x = 0.02. Adiabatic temperature change for co...

We introduce shrubs in this paper in order to present a first approach to studying the structure of the Mandelbrot set. Primary, secondary ... and N -ary shrubs are analyzed. We have experimentally obtained formulae to calculate the periods of the hyperbolic components representatives of the structural branches, and the preperiods and periods of both the nodes -where structural branches emanate...
