Wirtschaftliche und soziale Ziele der kommunalen Gebietsreform

The purpose of this paper is to analyze socio-economic goals of the administrative-territorial reform in Estonia. An administrative-territorial reform has been a top issue since in Estonia regained its independence but there are virtually no results. In 1995, a law was passed granting the Government the right to take decisions on the country’s administrative-territorial division. Both the local authorities and the central government can initiate changes in the administrative-territorial division. By the spring of 2012, there were 226 local governments in Estonia, including 193 rural municipalities and 33 cities. The administrative-territorial organisation of Estonia needs changes. The average population of Estonian rural municipalities is less than 2,500 people and, in spite of mergers, there are still inexpedient units where the centrally located settlement is separated from its hinterland in administrative terms. However, one should be objective when preparing and implementing the administrative-territorial reform. The often expressed opinion that decreasing the number of rural municipalities would result in retrenchment of resources in terms of the number of local officials and administrative costs is misleading

Optical and mechanical properties of nanolaminates of zirconium and hafnium oxides grown by atomic layer deposition

Nanolaminates of ZrO2 and HfO2 were grown by atomic layer deposition, using metal halides and water as precursors, on silicon and fused quartz substrates at 300 degrees C. The crystalline phase composition, optical refraction, and mechanical performance of the multilayers were influenced by the relative contents of the constituent metal oxides. The crystal growth in as-deposited HfO2 dominantly led to the monoclinic phase, whereas ZrO2 was partially crystallized as its metastable and hard tetragonal polymorph. The hardness and elasticity of the nanolaminate structures could be modified by varying the amounts of either oxide contributing to the crystallographic order formed in the solid films. The refractive indexes depended on the nanolaminate structure.Peer reviewe

Behavior of nanocomposite consisting of manganese ferrite particles and atomic layer deposited bismuth oxide chloride film

Nanocomposites of manganese ferrite and bismuth oxide chloride were synthesized. The composites consisted of 10 nm thick nanocrystalline bismuth oxide chloride thin film grown by atomic layer deposition on spinel MnFe2O4 nanoparticles prepared by wet chemical synthesis. The composite layers exhibited nonlinear polarization behavior in both magnetic and electric fields at room temperature. The magnetic coercive force, HC, was 30 – 40 Oe at room temperature. The width of electrical charge – voltage hysteresis loop reached 3.6 MV/cm.Peer reviewe
