| 1 | Impact of high strength electromagnetic fields generated by Tesla transformer on plant cell ultrastructure显示文摘Non-thermal effects of direct electric fields and alternating electromagnetic fields(EMF)have been successfully used in a number of studies and applications in agriculture and biotechnology.Among different kinds of high strength EMF generators,the Tesla transformer(TT)is known as a widely applied,low cost,and troubleproof device,which generates EMF in the range of 2-8 MHz.Despite of a number of developed and perspective applications of high strength EMFs in agriculture and biotechnology,the EMFs generated by TT,as well as the 1-50 MHz range of high strength EMF still remain unexplored in the fields of plant physiology,ultrastructure studies and biochemistry.In this work,we have shown that TT-EMFs(4 MHz)induced fast stem and petiole bending,disappearance of cell organelles,vacuolar membranes,and increase of a non-photochemical chlorophyll fluorescence quenching in petioles.It is intriguing that such fatal effects can be evoked in plants by EMFs which are well known as harmless for man at the applied strength and frequency. | Anna Rusakova Igor Nosachev Vladimir Lysenko Ya Guo Alexander Logvinov Evgeniya Kirichenko Tatyana Varduny Sergey Cherednikov Olga Chugueva | 2017 | Information Processing in Agriculture2017，4，3： | 1 |
| 2 | Influence of two-stream relativistic electron beam parameters on the space-charge wave with broad frequency spectrum formation显示文摘We developed a cubic non-linear theory describing the dynamics of the multiharmonic spacecharge wave(SCW), with harmonics frequencies smaller than the two-stream instability critical frequency, with different relativistic electron beam(REB) parameters. The self-consistent differential equation system for multiharmonic SCW harmonic amplitudes was elaborated in a cubic non-linear approximation. This system considers plural three-wave parametric resonant interactions between wave harmonics and the two-stream instability effect. Different REB parameters such as the input angle with respect to focusing magnetic field, the average relativistic factor value, difference of partial relativistic factors, and plasma frequency of partial beams were investigated regarding their influence on the frequency spectrum width and multiharmonic SCW saturation levels. We suggested ways in which the multiharmonic SCW frequency spectrum widths could be increased in order to use them in multiharmonic two-stream superheterodyne free-electron lasers, with the main purpose of forming a powerful multiharmonic electromagnetic wave. | Alexander LYSENKO Iurii VOLK | 2018 | Plasma Science and Technology2018，20，3： | 0 |
| 3 | Plural interactions of space charge wave harmonics during the development of two-stream instability显示文摘We construct a cubically nonlinear theory of plural interactions between harmonics of the growing space charge wave(SCW) during the development of the two-stream instability. It is shown that the SCW with a wide frequency spectrum is formed when the frequency of the first SCW harmonic is much lower than the critical frequency of the two-stream instability.Such SCW has part of the spectrum in which higher harmonics have higher amplitudes. We analyze the dynamics of the plural harmonic interactions of the growing SCW and define the saturation harmonic levels. We find the mechanisms of forming the multiharmonic SCW for the waves with frequencies lower than the critical frequency and for the waves with frequencies that exceed the critical frequency. | Victor Kulish Alexander Lysenko Michael Rombovsky Vitaliy Koval Iurii Volk | 2015 | Chinese Physics B2015，24，9： | 0 |
