Reconstructive tomography is a new technique in diagnostic radiology for imaging cross-sectional planes of the human body /1/. A collimated beam of X-rays is scanned through a thin slice of the body and the transmitted intensity is recorded by a detector giving a linear shadow graph or projection (see fig. 1). Many of these projections at different angles are used to reconstruct the body-layer, usually with the aid of a computer. The picture element size of present tomographic scanners is approximately 1.1 mm2.Micro tomography can be realized using the very fine X-ray source generated by the focused electron beam of a scanning electron microscope (see fig. 2). The translation of the X-ray source is done by a line scan of the electron beam on a polished target surface /2/. Projections at different angles are produced by rotating the object.During the registration of a single scan the electron beam is deflected in one direction only, while both deflections are operating in the display tube.

Integration Challenge

The paper is devoted to the analysis of development prospects and problems of Eurasian Economic Union (EAEU) of Russia, Kazakhstan, Belarus and Armenia. It considers integration problems inside EAEU, interactions of EAEU with other CIS countries and with countries from the rest of the world. The paper shows that the major integration challenge inside EAEU is the domination of the redistributive motive over the creative one. It estimates the value of the oil and gas transfer from Russia to other EAEU members and the influence of the Russian tax maneuver on this transfer. The paper shows the need in redistribution mechanism inside EAEU as a necessary condition for getting the potential positive economic effects of free trade with other countries. It also assesses the risks for EAEU due to Russian embargo for food imports from countries of the sanctions list and possible application of tariff in the trade with Ukraine.
