abstract this survey tries to use of competitive advantage analysis of agricultural productions with shift share method. to arrive this target used of official published statistics in ten years priod (1374-1384) were used. the results explained north khorasan has competitive advantage in onion, melon, tomato and grape production. also in this survey, appointment potentials of low plant surface ...
Policies are used to control the behavior of large-scale systems. After policies are designed and before policies are implemented, it should be possible to analyze the policies and verify that they behave as expected. Graph transformations provide a good method to carry out the analysis and verification because of the intuitive representation of policies and the mature theory. Here, we show how...
A phase-field approach for quantitative simulations of grain growth in anisotropic systems is introduced, together with a new methodology to derive appropriate model parameters that reproduce given misorientation and inclination dependent grain boundary energy and mobility in the simulations. The proposed model formulation and parameter choice guarantee a constant diffuse interface width and co...
Note that if ∑ agg ∈ I, then ∑ ag = 0 so that ∑ agg = ∑ agg− ∑ ag1 = ∑ ag(g−1), so that every element in I is a Z-linear combination of the elements g− 1 (g ∈ G, g 6= 1). Also, if ∑ ag(g− 1) = 0, it follows that ag = 0 for all g so that the elements g − 1 (g ∈ G, g 6= 1) are linearly independent. (b) Notice that the ideal generated by the elements s− 1 (s ∈ S) is the same as the ideal generated...
truction combined with measures such as the improvement of dwelling houses and the better storage of grain to lessen the rat population? Admittedly the I M. S is merely advisory in such matters, but for what it is worth I venture to express the following opinions, viz. (i) That in years to come it will be recognised that the one and only method of dealing successfully with Bubonic Plague is rig...
La inclusión de cultivos servicios en rotaciones agrícolas posee muchas ventajas términos conservación recursos y sostenibilidad los sistemas productivos. Si bien a nivel país es una práctica aumento constante, la provincia Santa Fe, su implementación, está etapa exploratoria. Para fomentar el objetivo este trabajo evaluar, económicos, incorporación servicio frecuentes del centro Fe. Se compara...
