Published: February 2022

Abstract
Modern agriculture is characterized by a continuous increase in production, which is inextricably linked with the growth of consumption of fuel and energy resources (FER). The consumption of motor fuel for agricultural enterprises is about 40% of the total consumption of fuel and energy resources. The use of motor fuel inevitably leads to emissions of pollutants. Predicting the negative impact on the environment depends on the quantity and quality of these emissions. The purpose of the research is: analysis of forecasting methods; selection and justification of the most attractive forecasting method; planning of measures to reduce emissions into the environment. The statistical method of forecasting, which uses the theory of multidimensional dynamic stochastic processes, is the most attractive. The development and implementation of measures developed taking into account the analysis of the forecast of the negative impact on the environment of vehicles of agricultural enterprises will reduce the negative impact on the environment by introducing energy-efficient technologies into the energy balance of the enterprise.

Abstract
The work objective was an analysis for the petroleum prospectivity of a core from the Marcellus Formation of Western Pennsylvania, USA. In accordance with the investigation results, two sample groups were delineated based on TOC and S1free oil measurements of the analyzed core and the most prospective interval for further development was marked out. Core analysis on a Marcellus TST sequence overlain by undetermined sequence Marcellus core was done using pyrolysis and SEM XRF measurements together with GR (Gamma Ray), ChemoGR (calculated from Potassium, Thorium and Uranium), Porosity and PHIE (Effective Porosity) logging. Oil saturation was measured using both Classical Pyrolysis and HAWK-PAM methods. HAWK Petroleum Assessment MethodTM is advanced multiramp/multizone pyrolysis method that utilizes five zones using multiple ramp and isotherm routines assigned during a single sample analysis. A ramp rate of 25°C is utilized to generate five petroleum peaks – four on oil fractions and one on kerogen. The efficiency of the HAWK-PAM pyrolysis method is shown for determination of the sweet spot intervals that is particularly important for the development of hard-to-recover unconventional reservoirs like the Marcellus Formation in USA or the Bazhenov Formation in Russia.

Abstract
Forest wild fire prevention that is carried out to minimize of wild fires number and possible damage from them, is inconceivable without the development of fire-prevention procedures, which are based on data from wild fire monitoring. One of the areas of wild fires monitoring is the evaluation of forest wild fires spreading ability to transportation of firebrands by the wind. This way observed at crown-type of forest wild fires, which are formed from ground ones by transferring the flame to the trees crowns when the wind reaches a certain speed. A mathematical model has been developed for the firebrands transportation by the wind. Mathematical model adequacy was evaluated by inclusion of transfer coefficient as a ratio of firebrand speed to wind speed. The modeling of the horizontal firebrands transportation (sphere, cylinder and disc) has been carried out. Experimental conditions are firebrands have various sizes, fall off from a height of 5-20 m, at a wind speed of 1-5 m⋅s-1. Spherical and discshaped particles have the best transportation ability. The adequacy of the model of horizontal firebrands transportation has been experimentally proved by conducting our own experiments and analyzing information obtained from the literature on similar studies. The results of the experiments showed that with an increase in the air flow speed up to 10 m⋅s-1, the speed of the burning particle does not exceed the speed of the air flow that stimulates it. Thus, it is shown that within the air flow velocity of 1-10 m⋅s-1, the value of the transfer coefficient does not exceed one.

Published: February 2022

Abstract
The article presents the results of studies of technogenically contaminated soils in the territory of an asphalt concrete plant. Toxic dust generated by the operation of the enterprise pollutes the air and settles on the surface of the soil. This anthropogenic impact is visually manifested in a decrease in the projective cover of the vegetation cover in the Baiterek region of the West Kazakhstan region. The studies represent the study of such parameters as wind direction, soil composition for readily soluble salts, heavy metals and oil products. In the analysis of soils for heavy metals and oil products, spectral and fluorescent methods were used. Easily soluble salts in an aqueous extract were determined by electrochemical, gravimetric, and direct titration methods. The dynamics of the accumulation of pollutants in the soil corresponded to the winds operating in the zone of the plant. In the northern and western directions from the plant, the analysis of soils for lead and cobalt showed that the permissible norms were exceeded by 5.8 and 6.1 times. The dynamics of petroleum products in the plant's soils also revealed that the approximate permissible norms were exceeded. Analysis of the salt content in the technogenic sediment showed an average salinity within the entire production site. As a result of the research carried out, we found out that the functionality of the plant, represented by the welding, boiler, asphalt mixture production units and the vehicle fleet, really exerts a technogenic load on the soil and vegetation cover. The authors recommend excluding the construction of residential buildings and livestock grazing in the northern and western directions from the design.

Abstract
The article provides analytical dependences for calculating such important parameters of the cutter for soil cultivation as the number of revolutions of the shaft with the knives fixed on it, the indicator of the kinematic regime, feed to the knife, as well as the power consumed by the cutter. Taking into account the results of research by other authors, numerical calculations were carried out. The following are the results of experimental studies of the process of milling the soil, carried out using a prototype machine. The torque on the drive shaft of the machine was determined using the strain gauge method. To determine the rotational speed of the cutter shaft, optical sensors were used, the translational speed of the machine was determined based on the processing of signals from a speed meter driven by the support wheel of the machine. As a result, it was found that the milling cutter with the values of the parameters determined theoretically provides high quality soil cultivation. The calculated values of the power consumed by the cutter are in good agreement with the experimental results.
