Grain Seed Treatment by a Low-Frequency Electromagnetic Field

The paper notes the potential for enhancing seed productivity through exposure to an electromagnetic field. It touches upon both theoretical and practical considerations for developing an experimental laboratory plant for pre-sowing seed treatment using a low-frequency electromagnetic field and aiming to achieve a magnetobiological effect. (Research purpose) The study aims to investigate the influence of low-frequency electromagnetic field on the composition and properties of grain seeds. (Materials and methods) Standard emitters, characterized by a magnetic induction variability of 3-75 millitesla and a radiation frequency of 1-100 Hertz, were employed to ensure the necessary treatment parameters for a batch of seeds. (Results and discussion) The study investigates the impact of magnetization on the germination process, germination energy, and the physical and chemical properties of seeds subjected to different parameters of a low-frequency electromagnetic field (ranging from 3 to 75 millitesla in magnetic induction and a radiation frequency of 10-16 Hertz).The quality of the effect was analyzed with respect to the installation parameters and seed mass, ranging from 10 to 500 grams, across various cereal crops. Subsequently, specific modes were identified, and a functional irradiation program was devised to ensure a highly effective impact on seeds, optimizing their germination, sprouting and development. (Conclusions) The impact of a low-frequency electromagnetic field on the composition and properties of grain has been studied. An experimental laboratory plant with sources of a low-frequency electromagnetic field has been developed and irradiation modes have been justified. The pre-sowing treatment of an industrial batch, the magnetobiological effect is contingent upon several factors, including the crop type and variety, activation of a biological complex in a cell that initiates the development of a seedling, seed quality and moisture content, the presence of microorganisms on the surface, pathogenic ones included, and the characteristics of irradiation sources and energy parameters. The parameters of the low-frequency electromagnetic field were determined as follows: magnetic induction ranging from 3 to 75 millitesla, a frequency 10-16 Hertz, and seed weight varying from 10 to 500 grams. These identified parameters will be applied in the development of an industrial unit designed for the preparation of seed material and enhancement of its sowing properties.

Changes in Free Radical Processes under the Influence of Low-Frequency Electromagnetic Field in Rats.

We studied the effect of a low-frequency (LF) electromagnetic field (EMF) on the state of the antioxidant system of Wistar rats in vivo. It was found that changes in activity of antioxidant enzymes and H2O2 content in the blood plasma of rats exposed to LF EMF depended on the frequency of EMF. We propose a mechanism of the protective effects of low doses of ROS the generation of which is stimulated by LF EMF.

Влияние низкочастотного электромагнитного поля на лабораторную всхожесть семян и выход сеянцев сосны обыкновенной (Pinus sylvestris L.)

The results of research that was conducted in 2017 in the laboratory of the Department of Forest crops, breeding and dendrology of the BMSTU (Mytishchi branch) and in the Pravdinsky nursery of the Pushkin forest technical College of the Moscow region. The purpose of the study was to determine the effectiveness of the influence of low-frequency electromagnetic field (EMF) on laboratory and ground germination of common pine (Pinus sylvestris L.) seeds with low seeding characteristics. Samples of common pine seeds of the 3rd quality class were selected for the study (collection 2014). The seeds selected for the study were treated with low-frequency EMF using POSEP technology (pre-sowing seed treatment with an electromagnetic field) with a low-frequency generator Rost-Active. One part of the seeds was laid for germination in the laboratory in 4-fold repetition, the other was sown in the sowing Department of the Pravdinsky nursery in 3-fold repetition, control was served by unprocessed seeds. As a result of pre-sowing treatment of pine seeds, laboratory germination exceeded the control by 25 %, and approached the indicators for class I seeds. In the Pravdinsky nursery, the yield of 1-year-old seedlings increased by 16 %, and their height was 47 % higher than the control. The results of laboratory and field studies have demonstrated the high efficiency of pre-sowing treatment of common pine seeds using POSEP technology and its ability to restore the seed quality after long-term storage, increase the yield of seedlings and improve their biometric indicators.

Low-frequency electromagnetic field influences human oral mucosa keratinocyte viability in response to lipopolysaccharide or minocycline treatment in cell culture conditions

The aim of the current study was to investigate the influence of low-frequency electromagnetic field (LF-EMF) exposure on viability parameters of oral mucosa keratinocytes cultured in in vitro conditions. The effect of LF-EMF stimulation on cell viability was also specified in the simultaneous presence of lipopolysaccharide (LPS) infectious agent or minocycline (Mino) anti-inflammatory agent. Viability parameters such as early-, late apoptosis and necrosis of keratinocytes were analysed by the flow cytometry method (FCM).The exposure of human oral keratinocyte cell cultures to LF-EMF acting alone or combined with LPS/minocycline agents caused changes in the percentage of cells that undergo programmed or incidental cell death. The overall obtained results are compiled in a graphical form presented in Fig. 1.

The nature of axonal arborization occurring under the action of low-frequency electromagnetic fields.

Background. Previously, it was found that the drying of salt solutions prepared on water with a negative charge is accompanied by the arborization of salt crystals, i.e. – the formation of needle- or plant-shaped crystals. It was also found that low-frequency electromagnetic fields stimulate the regeneration of damaged neurons. Objective. The aim of the work was to test the hypothesis that negative electrization of the cytoplasm of neurons, as well as their axonal arborization, can occur under the influence of low-frequency electromagnetic fields. Methods. For the negative electrization of aqueous solutions of chlorides, various low-frequency (0 ÷ 100 Hz) EMF generators were used. Negative electrization of aqueous solutions of chlorides was visualized using the method of sensitive crystallization. Results. It is shown that under the action of low-frequency electromagnetic fields, arborization of chlorides, which are the main salt components of the cytoplasm of cells, including neurons, occurs. This made it possible to explain the nature of axonal arborization of damaged neurons, which is observed under the influence of low-frequency electromagnetic fields in vivo. Conclusion. Under the action of low-frequency electromagnetic fields, negative electrization of aqueous solutions of chlorides occurs. By preliminarily optimizing the content of chlorides in the body, it is possible to create optimal conditions for the axonal arborization of neurons and the formation of new capillaries using low-frequency electromagnetic fields.

Statistical Analysis of Circulating Water Quality Parameters under Variable-Frequency Vertical Electromagnetic Fields

No unified electromagnetic anti-fouling mechanism is currently available. Most research has focused on the effects of structural parameters and water quality parameters on electromagnetic fields; variations in water quality parameters under the influence of electromagnetic fields have not been reported. A variable-frequency vertical electromagnetic field is proposed in this study. Relationships between conductivity, pH value, dissolved oxygen, turbidity, fouling resistance, and magnetic acting time were carefully analyzed using statistical analysis. Results show that the conductivity difference was the most explanatory predictive variable on magnetic acting time in the multiple stepwise regression model. Magnetic acting time has a greater impact on conductivity than pH value and dissolved oxygen. Conductivity is used as an adaptive feedback control parameter for the optimum anti-fouling state. Fouling resistance on the heat-exchanging surface of the magnetic experiment was smaller than that of the contrast experiment. The anti-fouling efficiency in 1 kHz and 5 kHz magnetic and contrast experiments was 91.23% and 46.97%, respectively. Better anti-fouling performance was realized under the influence of low-frequency electromagnetic fields, confirming that physical water treatment is an effective and environmentally friendly method to eliminate heat exchanger fouling. This research serves as a reference for the development of an electromagnetic-adaptive closed-loop water treatment device.

95/00888 Influence of low-frequency electromagnetic fields on living organisms

A vacuum degasifier is used to remove dissolved gases in water for many industrial processes. The present industrial design of these vacuum degasifiers use simple methods and formulae, which normally involve the removal of common gases such as oxygen and carbon dioxide only. In this study, a comprehensive modelling and computer-aided design procedure is presented. It incorporates the removal of both non-ionized gases (i.e. oxygen, argon, nitrogen and methane) and ionized gases (i.e. carbon dioxide, hydrogen sulphide and ammonia) in various applications. The vacuum pumps used are the NASH liquid ring types and the packings are of the MASPAC model types.
