The Impact of Terrorist Activities on the Economy of the State

The article sets a task to examine the consequences of terrorist activities and its impact on the economy of the state. Because of the analysis, the author concludes that terrorist acts have an impact on the economy in the short-term period, but it always recovers because of the transfer of economic activities of the population to the following periods. Keywords: terrorism, economy, investment

Electronic load as part of the test complex of the power processing unit of electric and plasma propulsion

This article provides the advantages and technical solutions for the use of electronic loads as part of a testing complex of power and management systems of electric and plasma propulsion of three types. The paper shows the parameters that were applied to select the electronic loads and describes their functionality

Single-electron transistor effect in a two-terminal structure

A peculiarity of the single-electron transistor effect makes it possible to observe this effect even in structures lacking a gate electrode altogether. The proposed method can be useful for experimental study of charging effects in structures with an extremely small central island confined between tunnel barriers like a nanometer-sized quantum dot or a macromolecule probed with a tunneling microscope), where it is impossible to provide a gate electrode for control of the tunnel current.Comment: 5 pages, 2 figure

Preparation of the Sm3+-doped magnetic nanoparticles via microwave-assisted polyol synthesis

Sm3+-doped magnetic nanoparticles (NPs) were prepared via microwave-assisted polyol synthesis in ethylene glycol, poly(ethylene glycol) and mixed ethylene glycol - poly(ethylene glycol) solutions. In present work, the effects of organic solvent composition on particle size, particle size distribution, extent of agglomeration, and samarium content in prepared NPs were studied. The synthesized NPs were characterized by several techniques as follows: X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetry (TGA) and X-Ray fluorescence (XRF) analysis. XRD and TEM results showed formation of ~6.0 - 17.9 nm NPs having different microstructure characteristics (average particle size, particle size distribution, and agglomeration
