Determination of the Performance Characteristics of a Traction Battery in an Electric Vehicle

The research was conducted to study the influence of electrophysical effects on melon seeds and their development, as well as to identify the most effective variant of pre-sowing stimulation and treatment mode. As an agro-technological task, we evaluated the possibility of realising the development potential inherent in the seeds of melon plants, which could be realised using electrical stimulation, with minimal negative impact on the ecology of the environment. To study the effect of high voltage electric fields (DC, AC, pulse) on gourd seeds before sowing, a specially assembled setup was used. Treatment of pumpkin seeds in the electric field of constant high voltage showed that on the 3rd day there were 100% of germinated seeds, in the electric field of variable high voltage – 50%, in the electric field of pulsed high voltage – 30%, pumpkin seedling in the treatment in the electric field of constant high voltage was longer in 9.0 and 3.6 times than in the control and other treatments; treatment of watermelon seeds in the electric field of constant high voltage showed that on the 3rd day there were 70 % of germinated seeds, in the electric field of variable high voltage – 20 %, in the electric field of pulse high voltage – 40 %; watermelon germ at treatment of seeds in the electric field of constant high voltage was longer in 1,5…2,0 times than in the control and other treatments.2.0 times longer than in other treatments. High effect on the destruction of pathogenic microorganisms was observed when seeds were treated in the electric field of pulsed high voltage – the number of pathogenic microorganisms on the seed coat of watermelon and pumpkin was 4.25 and 4.1 times lower compared to the control; when treated in the electric field of constant high voltage, their number was also 3.0 times less, but the treatment of seeds in the electric field of alternating high voltage recorded an increase in pathogenic microflora in 2.0 and 1.2 times. The highest yields of watermelon and pumpkin were obtained with pre-sowing seed treatment in the electric field of constant high voltage – by 25.5 and 37.8 %; in the field of alternating voltage – by 15.7 and 27.0 %; in the field of pulse voltage – by 9.8 and 5.4 %.

Integral assessment of the environment using the bioindication methods

et al. 2024

Bioindication is an assessment of environmental factors and their dynamics based on the properties of ecological or biological systems. Bioindication methods are easily applied in monitoring of the environment. Bioindication is one of the areas of modern ecology based on the environmental laws, assessing (diagnosing) environmental factors and the state and dynamics of ecosystems by the biotic characteristics. Its object is ecological properties and biological characteristics, and its subject is patterns of the relationship of these characteristics (properties) between themselves and with biotic factors. Bioindication reflects the influence of factors external to the biosystem, including the anthropogenic ones. The main purpose of this study is to assess the state of the atmosphere, hydrosphere and soil using thebioindication and biomonitoring methods. A comparative analysis and mathematical processing of data were carried out depending on the level of soil pollution.

This article is a study of the existing management structure and organizational structure of the operation department at a trucking company. The purpose of the study was to identify the uneven distribution of workload among employees and to develop an ideal business process model to optimize the work of the department. Using the methods of business process analysis, the main functions and their labor intensity were identified and the workload of the staff was calculated. After implementing the proposed changes based on the ideal business process model, there is a significant equalization of employee workload and a decrease in the total labor intensity of functions. The obtained results indicate an increase in the efficiency of the operation department and optimization of the use of enterprise resources.
