ANALYSIS OF THE WORLD EXPERIENCE OF AGRICULTURAL LAND USE FORMATIONWHILE SPATIAL PLANNING OF TERRITORIES
The land management method is the main instrument for the organization of
sustainable use and protection of land in the process of agricultural land use formation in
spatial planning of territories.So, it is important to consider the effectiveness of the
existing land management system as an ecological and economical tool for sustainable
development of the agrarian sector. The discussion of the formation of the highly
efficient agricultural land use in Ukraine is conducted while reviewing the world
positive experience regarding the realization of the main principals of the spatial
planning of territories. In this study, the international experience of land-use planning
while sustainable use of agricultural lands is analyzed. A core of the main spheres of
implementation of the world experience in spatial planning of the territories while
applying ecological and economical mechanisms of sustainable use of lands in Ukraine
is reviled. In this paper, the international experience of using the land management
mechanism for providing sustainable use of agricultural lands that are based on spatial
planning of rural areas as independent objects of management is studied
Photoemission spectroscopy of clean and potassium-intercalated carbon onions
Hollow onionlike carbon (OLC), generated by annealing nanodiamond at 2140 K, has been studied by core-level and valence-band photoemission spectroscopy. Upon intercalation with potassium, core and valence states of the OLC show an almost rigid shift to higher binding energies, and the density of states at the Fermi level (EF) is observed to increase. An asymmetric broadening of the C1s line from the OLC as intercalation proceeds indicates an increase in electron-hole pair excitations. Both core and valence-band spectra are consistent with charge transfer from the intercalated potassium to the OLC, and support the conclusion that the electronic structure of the carbon onions bears strong similarity to that of graphite, although differences do exist. In consequence the conclusion can be drawn that these species behave as graphite ``nanocrystals'' rather than as large fullerene molecules
