A new method is suggested for the accurate determination of the incident beam direction K, crystal thickness t and the coordinates of the basic reciprocal lattice vectors V1 and V2 (Fig. 1) of the ZOLZ plans in pixels of the digitized 2-D CBED pattern. For a given structure model and some estimated values Vest and Kest of some point O in the CBED pattern a set of line scans AkBk is chosen so that all the scans are located within CBED disks.The points on line scans AkBk are conjugate to those on A0B0 since they are shifted by the reciprocal vector gk with respect to each other. As many conjugate scans are considered as CBED disks fall into the energy filtered region of the experimental pattern. Electron intensities of the transmitted beam I0 and diffracted beams Igk for all points on conjugate scans are found as a function of crystal thickness t on the basis of the full dynamical calculation.

Cherry Trees

The possible effect of shaker harvest on root damage of 10-year-old cherry trees was studied on a simple tree structure model. The model was composed of elastic trunk and rigid main roots, the ends of which were connected to the surrounding soil via springs and dumping elements. Equations were set up to be able to calculate the relation between shaking height on the trunk and strain in the roots. To get the data for root break and their elongation at different shaking heights on the trunk, laboratory and field experiments were carried out on cherry trees and on their roots. Having evaluated the measured and calculated data it could be concluded that root damage is to be expected even at 3.6% strain and the risk of it increases with increased trunk amplitudes, i.e.with the decrease of shaking heightat smaller stem diameters (i.e. in younger plantation), andif the unbalanced mass of the shaker machine is too large for the given tree size.

AbstractAtomic resolution high-voltage transmission electron microscopy and electron energy loss spectroscopy were performed on grain boundaries of boron-doped diamond, cooperated with the ab-initio calculation. Segregated boron in the {112}∑3 boundary was caught by the EELS spectra. The change in atomic structure of the segregated boundary was successfully observed from the image by ARHVTEM. Based on the ARHVTEM image, a segregted structure model was proposed.

Subject. Foreign economic and trade ties among countries are getting tighter and less predictable in the early 21st century. This directly stems from a growing disparity of partners, especially if it goes about their future cooperation as part of integration groups or international organizations. Communities of experts suggest using various approaches to locally adjusting integration phases, especially implementing the two-speed integration in the European Union. Objectives. The study is an attempt to examine an improvement of foreign economic cooperation and suggest its implementation steps for the European Union. This all is due to considerable inner controversies and problems within the EU, which grow more serious year by year. Methods. The methodological framework comprises the historical logic, dialectical principles, scientific abstraction method. The process and system approach was especially important for justifying the implementation of the above steps. It was used to examine foreign economic relations of partners in the European Union. Results. The article sets forth the theoretical and methodological framework for the geostrategic economic bloc, including a conceptual structure model. I present steps to implement a foreign economic cooperation of partners in the EU in terms of its form. Conclusions and Relevance. Should the form of the foreign economic relations among the EU countries be implemented, counties at the periphery of the EU will be able to become active parties to the integration group.
