A simulation of low-frequency electromagnetic phenomena in kinetic plasmas of three dimensions
(1993)
An advanced kinetic simulation method has been developed and implemented in the HIDENEK code to study large space-scale, low-frequency electromagnetic phenomena occurring in inhomogeneous plasmas. The present method is ...
Kinship relations and economic interdependence in family agriculture of the Greek plain
(1993)
Small famliy holdings created by the agrarian reform since 1992 remain nowadays the major feature of the agrarian structure in the lowlands of central and northern Greece. Agriculturists are able to rent and cultivate ...
LARGE-AMPLITUDE INTERFACIAL WAVES ON A LINEAR SHEAR-FLOW IN THE PRESENCE OF A CURRENT
(1993)
The properties of two-dimensional steady periodic interfacial gravity waves between two fluids in relative motion and of constant vorticities and finite depths are investigated analytically and numerically. Particular ...
NUMERICAL TREATMENT OF THE HEAT-TRANSFER FROM WALL TO FLUIDIZED-BED USING THE PARTICLE MODEL
(1993)
The wall-to-fluidized bed conductive heat transfer process is studied in the case of glass particles, applying the ''particle-model''. A very accurate numerical method is developed within the implicit finite-difference ...
A DERIVATION OF MOLECULAR VIBRATIONAL-ROTATIONAL HAMILTONIANS
(1993)
The problem of collective molecular coordinates is examined within the Hamiltonian formalism by enlarging the number of degrees of freedom and transforming the model to a gauge theory (a theory where the solutions to the ...
NEW FORMS OF GEOGRAPHICAL INEQUALITIES AND SPATIAL PROBLEMS IN GREECE
(1993)
The dynamics of the restructuring of capital over the last fifteen years produced new territorial realities. One fundamental aspect of this evolution, in the case of Greece, is the relative decrease of interregional ...
EXCIMER-LASER USED AS A MATERIALS CHARACTERIZATION TOOL - SULFIDE INCLUSION PRINTING IN STEEL
(1993)
An application of the excimer laser in the area of material characterization making use of its ablative ability to perform surface sulphur printing is presented. It is shown that the differential ablative and surface melting ...
KINETIC-STUDY OF PHOSPHORUS DESORPTION BY ALFISOLS AND ENTISOLS
(1993)
The kinetics of phosphorus (P) desorption by six Greek soils, four Alfisols and two Entisols, have been studied. By the addition of several amounts of P fertilizers at different water/soil rations and different contact ...
Phenomenological features of precipitation series in agricultural regions
(1993)
A region in central Macedonia of northern Greece is used for the analysis, where the availability of water is mandatory for the agricultural activities of the region. Seven stations are employed with a 10-year record of ...
