Talmi's method of calculating coefficients of fractional parentage to states forbidden by the Pauli principle. Abstract In a previous work we studied the effects of setting all two body T=0 matrix elements to zero in shell model calculations for 43 Ti (43 Sc) and 44 Ti. The results for 44 Ti were surprisingly good despite the severity of this approximation. We found degeneracies in this approxi...

The effect of setting all T=0 two body interaction matrix elements equal to a constant (or zero) in shell model calculations (designated as < T = 0 >= 0) are investigated. Despite the apparent severity of such a procedure, one gets fairly reasonable spectra. We find that using < T = 0 >= 0 in single j shell calculations degeneracies appear e.g. the I =

PELOIDS CONSIST OF humus and minerals formed over a very long period by physical, chemical, biologic, and geologic processes. They are used in treatment either in their natural state or after fermentation. They are applied as poultices or in the forms of baths. They are sometimes used internally. Of the many classification proposed, we shall discuss only the more important ones: humolites and m...

Multivariate methods have been widely used for revealing the structures of communities, and in this paper we explore one particular method, namely correspondence analysis (also called reciprocal averaging) for studying humus profiles by the 'method of small volumes'. The present study was done on humus profiles under holm oak (Quercus rotundifolia), an evergreen Mediterranean species, in the Hi...

Based on the characteristics of Lycoris aurea (L. aurea) natural distribution and local soil types, we selected four representative types of soil, including humus soil, sandy soil, garden soil and yellow-brown soil, for conducting the cultivation experiments to investigate key soil factors influencing its growth and development and to select the soil types suitable for cultivating it. We found ...

1 2 The common development of vegetation and soil is a central question of plant succession. We 3 asked whether places where aerial parts of woody vegetation die and accumulate on the 4 ground (zones of destruction or 'micro-chablis') played a role in the successional 5 development of vegetation patches on tropical inselbergs and whether causes could be 6 inferred from the analysis of the organ...
