... Good representation of the experimental SH intensity and phase spectra is provided by a line shape of the quadratic susceptibility calculated both with excitonic and two-dimensional 2D types of E 2 ( X , ) CP's. The line-shape dependence of resonance energies, namely, repulsion of nearby E 2 ( X , ) resonances in the case of a 2D CP in comparison with the excitonic ones, is observed. ... It deals with SH intensity and phase spectra which are two independent combinations of resonance parameters. ...

... In the geometry of measurements to be specified below , where the anisotropy is most strongly pronounced, the coincidence angular distribution in a far zone will be shown to be much narrower than both the same distribution in the orthogonal geometry and the pump. ... FIG. ... Figure 8 shows two sets of experimental angular distributions solid line received in a single-particle and b coincidences measurements, which are plotted together for dif- ferent geometries, with a slit broadened pump beam. ...

Judging the pedogenic development of soils and paleosols seems simple until more than three kinds of soils are considered. ... SD is commonly described as weak, moderate or strong (or poor, moderate or well), a 3-class system that can be modified with adjectives. ... A scale for ranking soil and paleosol development. ... An effective paleosol classification requires delineation of those key attributes in modern soils with a moderate to high preservation potential following burial and diagenesis. ...

... He distributes these gifts in sacks (each sack can contain from 1 to n items) and puts the sacks with gifts around the Christmas tree (only the content of the sacks and their ordering on the circle around the tree are important). ... A river falling into a sea forms a delta which is a system of branches consisting of channels without inner intersections. (a) Suppose that in a given delta there are exactly n different (i.e. differing by at least one channel) routes down the stream. ...
