AbstractA generalized technique has been developed that reduces the contributions of nonlinear effects that occur during measurements of natural electric fields around thunderstorms by an array of field mills on an aircraft. The nonlinear effects can be due to nearby charge emitted by the aircraft as it acquires and sheds charge, but the nonlinear effects are not limited to such sources. The generalized technique uses the multiple independent measurements of the external electric field obtained during flight to determine and remove nonlinear contaminations in the external vector electric field. To demonstrate the technique, a simulated case with nonlinear contaminations was created and then corrected for the nonlinear components. In addition, data from two different field programs utilizing two different aircraft and field mill configurations, each containing observable and different nonlinear effects, were also corrected for the significant nonlinear effects found in the field mill outputs. The expanded independent measurements in this new technique allow for the determination and correction of components in the field mill outputs from almost any measurable source. Alternate utilization of the technique can include removing effects in the aircraft charging such as aircraft altitude, cloud properties, engine power settings, or aircraft flap deployment. This technique provides a way to make more precise measurements of the true external electric field for scientific studies of cloud electrification.

Modern lasers are unable yet to cause electron–positron pair production in vacuum, however it is possible to notice considerable influence of vacuum polarization on radiation that propagates in such medium. In our work we present nonlocal theory of interaction of intensive laser radiation with electron–positron vacuum. We refuse from Heisenberg–Euler approximation and it permits us to calculate nonzero response of vacuum even for a plane wave. We show how to use the "proper time" method for calculation of corrections to the Maxwell equations. These equations are solved for the case of plane wave and their solutions are investigated.

The article presents the results of research on the formation of corn yield for grain depending on the elements of cultivation technology in the Forest-Steppe of Ukraine. The goal of the research was to identify the influence of plant density and fertilizer system on the yield of corn hybrids for grain. The research was conducted during 2017-2019 in the research field of Bila Tserkva National Agrarian University (Bila Tserkva NAU). Research methods: field, calculation and statistical. Results. Regularities of growth, development and formation of yield by plants are revealed, both in concrete conditions of years of researches, and taking into account average long-term values taking into account features of hybrid-oriented technology. According to the results of the experiment it was recorded that the maximum yields for growing early-maturing maize hybrid DN PIVYHA with FAO 180 in general were obtained at a pre-harvest density of 75 thousand units/ha and the use of combined organo-mineral fertilizer system - 11.09 t/ha; medium-early maize hybrid DN ORLYK, FAO 280 in general in the experiment provided a grain yield of 9.60 t/ha, and in terms of 2017 - 7.86 t/ha, in 2018 - 11.22 t/ha and in 2019 - 9, 72 t/ha, but the medium-ripe hybrid of corn DN SARMAT, FAO 380 provided a grain yield of 10.81 t/ha, and in the context of 2017 - 9.31 t/ha, in 2018 - 11.68 t/ha and in 2019 - 11.44 t/ha. Significant influence on the formation of the yield of corn has a hybrid factor (27 %), fertilizer system determines the level of productivity by 21 % and interacts closely with the conditions of the growing season (factor BV 9 %), growing season conditions also determine the level of productivity of corn plants (19 %), and the pre-harvest density determines this feature by 18 %. Conclusions: In the conditions of the Right Bank part of the Forest-Steppe of Ukraine there is an increase in the level of productivity of maize hybrids from early to medium-ripe hybrids, regardless of the influence of other experimental factors.
