A Study on the Electromagnetic Fields in Wind Mills Farm Area

9th International Conference on Ecological Vehicles and Renewable Energies (EVER) -- MAR 25-27, 2014 -- Monte Carlo, MONACO -- Monaco Dev Durable, IEEE Ind Applicat Soc, IEEE Power Elect Soc, IEEE Magnet SocThis study presents the mathematical model of electromagnetic waveforms parameters which can be used for determination of the electromagnetic pollution level in windmills farm. The electromagnetic field parameters such as electric field intensity and magnetic field density were measured by EMF detectors on different frequencies ranges. The measured values for the waveform reconstruction in time domain were processed using Inverse Discrete Fourier Transform (IDFT). Obtained wave shape of electric field strength as well as magnetic flux density allowed defining the general of electromagnetic radiation level in chosen measurement point of windmills farms which includes all electromagnetic radiation values from all possible nearby sources. Also analysis of electromagnetic radiation impact for environment was considered. The measurement parameters were compared with the limit values.WOS:0003602889000072-s2.0-8490447999

H + D₂ Reaction Dynamics in the Limit of Low Product Recoil Energy

Both experiment and theory recently showed that the H + D₂(<i>v</i> = 0, <i>j</i> = 0) → HD­(<i>v</i>′ = 4, <i>j</i>′) + D reactions at a collision energy of 1.97 eV display a seemingly anomalous HD product angular distribution that moves in the backward direction as the value of <i>j</i>′ increases and the corresponding energy available for product recoil decreases. This behavior was attributed to the presence of a centrifugal barrier along the reaction path. Here, we show, using fully quantum mechanical calculations, that for low recoil energies, the collision mechanism is nearly independent of the HD internal state and the HD product becomes aligned, with its rotational angular momentum <i><b>j</b></i>′ pointing perpendicular to the recoil momentum <i><b>k</b></i>′. As the kinetic energy to overcome this barrier becomes limited, the three atoms adopt a nearly collinear configuration in the transition-state region to permit reaction, which strongly polarizes the resulting HD product. These results are expected to be general for any chemical reaction in the low recoil energy limit
