Published: November 2021

The strength of P92 steel (tensile strength, specified plastic elongation strength) will decrease after its hardness is reduced, ferrite and carbides forming the structure. Carbides of grain size 5-6 are precipitated in the grains and grain boundaries. The martensite lath shape has completely disappeared. M23C6 carbide coarsened obviously, with a maximum size of about 500nm; The Laves phase is also aggregated and coarsened, connecting in a chain shape with a maximum size of more than 500nm. Evolution of microstructure, namely the obvious coarsening of M23C6 carbides and the aggregation and connection of Laves phases in a chain shape, are the main causes for rapid decrease in the stability of the material substructure and evident decline in mechanical properties and hardness. In addition, the MX phase did not change significantly, hardly affecting the hardness reduction of P92 steel.

Published: November 2021

Structures are easily corroded in the Salt Lake areas of China, especially in sulfate solution. This study was intended to settle the problem of sulfate corrosion failure of concrete structures, the influences of different contents of super absorbent polymer (abbreviated as SAP) on the working performance, mechanical properties, corrosion resistance and expansion performance of cement mortar were studied. The mechanism of SAP in mortar was analyzed and studied by SEM. The results showed that although SAP could slightly decrease the fluidity and strength of cement mortar, but it could remarkably improve the coefficient of resistance erosion of specimens and the inflation coefficient of cement paste. When the content of SAP was 0.3%, the sulfate corrosion resistance and expansion performance of specimens showed the best (the coefficient of resistance erosion and inflation coefficient of mortar specimens were 0.95 and 0.97, respectively). Besides, SAP could release much water in the hydration process, form irregular holes, and increase the porosity of mortar specimens. There would more hydration products generated and filled in the pores during the hydration process, thereby improving the sulfate resistance of mortar specimens. Therefore, this research provides theoretical guidance and basis for the study of sulfate corrosion damage of concrete structures in the future.

The SiC fiber was thermally treated in air atmosphere and the SiC fiber reinforced boron phenolic resin composite was prepared by hot molding process by introducing inorganic ceramic particles. The thermal stabilities, the surface microstructures, the diameter and oxygen mental content variations, and the crystal structures of SiC fiber heated and kept for 0.5 h and 1h at different high temperatures were investigated through TG, SEM, XRD analysis. The cross-section morphology of the composite also observed. The results showed that the SiC fiber had good thermal resistance at high temperature in N2, however it was easy to be oxidized at high temperature in air. When heated from 25 °C to 1600 °C and kept for 1 h, the fiber was oxidized to SiO2 and the fiber surface was coarse and cracked. With the temperature increasing, the diameter of the fiber decreased and the oxygen content increased. Highly different form the cross-section morphology of SiC fiber itself heated in air, the cross-section morphology of SiC fiber in composite was weakly oxidized and the cross section was smooth and there was no distinct oxidation layer existing.

Published: November 2021

In today’s world, the vast majority of people in large cities rely on automobiles. As a result, automobile parking has become an important part of our daily life. As a result, with such a vast population and a fast-paced world, vehicle parking has become a major concern. Such issues cause stress and strain, which might result in accidents. To help them out in such situations, a “smart” approach for running multilevel parking systems efficiently. To automate the parking procedure by monitoring metrics such as distance and available parking spaces, NodeMCU and IBM Cloud are used. The distance is measured, and the information is sent to Node-RED over the MQTT protocol. The Node-RED dashboard allows the user to view availability from any location. If the distance is too great, the space is unoccupied. If the parking area is fully occupied, the owner or person in control of the parking lot is also notified. This is accomplished by combining IFTTT and Node-RED. Watson is a virtual assistant that helps consumers with a variety of questions.

Published: November 2021

In the current process of producing vermicompost on a large-scale, the main challenge is to keep the worms alive. This is achieved by maintaining temperature and moisture in their living medium. It is a difficult task to maintain these parameters throughout the process. Currently, this is achieved by building infrastructure but this method requires a large initial investment and long-run maintenance. Also, these methods are limited to small-scale production. For large-scale production, a unit is developed which utilises natural airflow with water and automation. The main aim of this unit is to provide favourable conditions to worms in large-scale production with very low investment and minimum maintenance in long term. The key innovation of this research is that the technology used in the unit should be practical and easy to adopt by small farmers. For long-term maintenance of the technology lesser number of parts are used.

Published: November 2021

With the most advanced classification algorithms in the technological platform, the computational power requirement is on the surge. The paper hereby presents computationally trivial algorithms to simplify the process of computational intensive classifications techniques, especially in the Motion Classification arena. The proposed methods prove crucial in acting as a lightweight and computationally fast stepping stone to a fundamentally more significant application of Motion indexing and classification, Action recognition, and predictive analysis of motion energy. The algorithms classify the motions into linear, circular, or periodic motion types by following an appropriate execution order. They consider the tracked motion path of the object of interest as a sequence and use it as a starting point to perform all operations, resulting in a feature that can be classified into separate classes. Using a single parameter for classifying the motion engenders a faster and relatively more straightforward route to motion identification and elicits the algorithm’s uniqueness. Two algorithms are proposed, namely, Angle Derivative Technique and Determinant Method for classifying the motion into two classes (linear & circular). On the other hand, a different algorithm identifies periodic motion using the principle of correlation on the motion sequences. All the algorithms show an average accuracy of over 95%. It also elicited an average processing time of 15.6 ms and 19.86 ms for Angle Derivative Method and Determinant Method, respectively, and 31.2 ms for periodic motion on Intel(R) Core(TM) i3-5005U CPU @ 2.00 GHz and 8GB RAM. A dataset of camera-captured videos consisting of three motion types is used for testing while the proposed methods are trained on a dataset of motion described by mathematical equations with added 3σ noise levels.

Authors: Vaibhava Lakshmi R. , Radha S.
Published: November 2021

The time series forecasting strategy, Auto-Regressive Integrated Moving Average (ARIMA) model, is applied on the time series data consisting of Adobe stock prices, in order to forecast the future prices for a period of one year. ARIMA model is used due to its simple and flexible implementation for short term predictions of future stock prices. In order to achieve stationarity, the time series data requires second-order differencing. The comparison and parameterization of the ARIMA model has been done using auto-correlation plot, partial auto-correlation plot and auto.arima() function provided in R (which automatically finds the best fitting model based on the AIC and BIC values). The ARIMA (0, 2, 1) (0, 0, 2) [12] is chosen as the best fitting model, with a very less MAPE (Mean Absolute Percentage Error) of 3.854958%.

Published: November 2021

The Paris Agreement establishes a transparency framework for anthropogenic carbon dioxide (CO2) emissions. It’s core component are inventory-based national greenhouse gas emission reports, which are complemented by independent estimates derived from atmospheric CO2 measurements combined with inverse modelling. It is, however, not known whether such a Monitoring and Verification Support (MVS) capacity is capable of constraining estimates of fossil-fuel emissions to an extent that is sufficient to provide valuable additional information. The CO2 Monitoring Mission (CO2M), planned as a constellation of satellites measuring column-integrated atmospheric CO2 concentration (XCO2), is expected to become a key component of such an MVS capacity. Here we provide a novel assessment of the potential of a comprehensive data assimilation system using simulated XCO2 and other observations to constrain fossil fuel CO2 emission estimates for an exemplary 1-week period in 2008. We find that CO2M enables useful weekly estimates of country-scale fossil fuel emissions independent of national inventories. When extrapolated from the weekly to the annual scale, uncertainties in emissions are comparable to uncertainties in inventories, so that estimates from inventories and from the MVS capacity can be used for mutual verification. We further demonstrate an alternative, synergistic mode of operation, with the purpose of delivering a best fossil fuel emission estimate. In this mode, the assimilation system uses not only XCO2 and the other data streams of the previous (verification) mode, but also the inventory information. Finally, we identify further steps towards an operational MVS capacity.

In the conditions of the Moscow region, in 1993-2020, more than 1.0 thousand Triticale Wittmack cultivars were studied, including new varieties and lines, by using diallel crossings (DIAC) (5 × 5) and other field and laboratory experiments. Tests of varietal samples in DIAC in 2011-2012 using the method of Hayman (1954) showed that the traits of winter triticale are characterized by an additive-dominant inheritance scheme. The dominant genes made the main contribution to the increase in productivity traits, and the prospects of a particular cross-breeding combination depended on their concentration. In the competitive test (CSI) in 2015-2020, the best productivity was found in the Gera variety - 8.15 t/ha (the standard one is 7.29 t/ha). It is shown that over the past 25 years in the Federal Research Center “Nemchinovka” created more than 25 varieties of winter triticale, 12 varieties submitted to the State Register, 6 varieties are now in production, including variety Nina, released in 2013 for the Central region and combines with Samara Research Institute of Agriculture variety Capella, made to the State Register from 2019.

Published: November 2021

Winter wheat breeding aimed at improving productivity is one of the most difficult tasks, which is associated with this trait unusual complexity. The length of a vegetation period is an important adaptive and economically valuable property, which is closely related to productivity, grain quality, drought resistance, and diseases. To a greater extent, the productivity potential is associated with the length of individual interphase periods, each of which plays a certain role in productivity formation. The length of individual interphase periods of plant development is affected by temperature conditions and water regime. The data obtained show that during the years of study a higher productivity was formed by the varieties with a longer period ‘beginning of a spring vegetation period – a heading phase’ and ‘a heading phase – complete ripeness’. The total vegetation period for these varieties and lines was also for two-three days longer. In our trials the variety ‘Univer’ was the most productive with 9.82 t/ha with 252 days of the vegetation period. The line 1005/14 was also productive with 9.81 t/ha and 251 days of a vegetation period as well as the variety ‘Donskaya Stepp’ with 9.61 t/ha and 251 days.

The article presents the analysis of early-ripening and mid-ripening promising and cultivated soybean varieties that received a comprehensive evaluation under irrigation conditions over the past period (2016-2018) of breeding with the increase in atmospheric drought and dry hot wind days to 77 with a long-term average annual indicator of 47 days with a relative humidity of less than 30%. We developed the scientifically based model of highly productive soybean varieties (2021-2023) with a yield of 2.8-3.8 t/ha and the growth season of 105-122 days. The model is based on the established correlations of the main morphological and biological characteristics with the grain productivity of irrigated sowing. The model of soybean varieties reflects characteristics that ensure the responsiveness of plants to watering and resistance to prolonged manifestations of atmospheric drought: a long growth season, low linear plant growth, significant leaf surface area, photosynthetic potential, dry biomass yield, number of plants before harvesting, thousand-seed weight, long-term duration of the “flowering-beans filling” period. The model is complemented by the indicators of high protein and fat content in seeds, as well as their yield from a unit of harvesting area.

Published: November 2021

The article highlights the results of research in strip farming. The method of minimum soil tillage, a resource-saving working body ROPA and a soil tillage tool for strip ripping OMPO-5.6, which are designed to perform fine soil tillage with strip deepening, are proposed. Adjustment of loosening depth from bit is achieved within the range of 0.25-0.4 m and is selected taking into account the crop grown in the farm. Availability of undercutter tine allows to regulate parameters of continuous ripping zone. Parameters of treated and untreated strips are regulated by location of undercutter paw. The design of the tool provides a smooth adjustment mechanism by which the width of the cultivated strip can be changed within 0.25-0.35 m. This makes it possible to use the implement for different tilled crops. The technological process carried out by this working body helps to reduce the wounding effect on the soil through a simple technical solution. Installation of side undercutting discs allows cultivating the soil within a given strip, and the process of cutting the soil in a blocked environment improves the quality of treatment.

Published: November 2021

To preserve and restore disturbed lands and reduce the damaging impact on air, plants and soil, it is necessary to apply resource-saving technologies. Strip-till technology is recommended for tilled crops. The technical solution is offered to increase the efficiency of the working solution use due to the rational distribution on the objects of influence and increase of its uniformity. That is, it is possible to reduce the hectare rate of consumption of the working solution by using the method of strip chemical treatment of plants. This is achieved by the redistribution of the working solution between the row and the row with the cultivated plant. The technical solution is to equip the serial sprayer with two lines with spray nozzles and special separator bodies. After a quick changeover in the field without the use of special tools, it is possible to switch from continuous spraying to strip spraying and back. At switching over to strip spraying, the spray solution is sprayed strictly along the strips of cultivated plant growth and covers the whole surface of stem and leaves. This allows reducing the cost of liquid chemicalization agents application and accurately redistributing the working solution.

Researches on the study of predecessors and biologization techniques in field crop rotations were carried out in 2018-2020 in the dry steppe zone of the chestnut subzone of light chestnut soils of the Nizhneje Povolzhje region. It is necessary to grow biennial melilot for green manure as a fallow-growing crop in a grain-steam five-field crop rotation in order to increase the organic matter input into the soil. A significant increase in yield was achieved in chickpeas for winter wheat, its straw was plowed into the soil. The highest increase in the spring barley yield was provided during the chickpeas and sorghum cultivation, which straw entered the soil. When growing spring barley on safflower, its straw was plowed into the soil, the yield was also higher than the control variant. The highest grain yield was achieved in the control grain-fallow four-field crop rotation with complete fallow, where the cultivated crops straw was removed from the field and grain-fallow-grass green manure seven-field crop rotation with seed fallow, where straw and melilot were plowed into the soil. Grain-fallow seven-field and grain-fallow-grass-cultivated green manure seven-field crop rotations, where oats and phacelia straw and green manure mass entered the soil, were inferior to the control.

For the first time in the zone of chestnut soils, complex scientific studies of resource-saving methods for increasing the productivity of vegetable crops in an acutely arid climate by regulating physiological and biological processes during drip irrigation were conducted and a system for applying these methods was developed. Research in the experiment was carried out according to generally accepted methods. As research has shown, irrigation and the use of mineral fertilizers and a growth regulator to a certain extent affected the content of dry matter, vitamin C and raw fiber in the fruits of sweet pepper and other indicators. The maximum amount of dry matter was observed on the variant N300P180K165 + Rastvorin + Energy-M on the Pompeo F1 hybrid – 7.98 and 8.06%, respectively, according to irrigation modes. Indicators such as vitamin C, fiber and sugar content in fruits increased with the improvement of the nutritional and water regimes of sweet pepper growth. As the result of the variety study of vegetable crops of domestic and foreign selection, the best was the Pompeo F1 sweet pepper hybrid, which surpasses the standard variety of the Podarok of Moldova by 30.10 t/ha, on average for irrigation modes.

The complex conditions of the modern period of agricultural production development determine the need to develop new elements of technologies adapted to modern conditions of land use. The article presents the results of studies of the growth regulator effect on obtaining high-quality tomato products. It is proved that the organosilicon preparation Energy-M stimulated the growth and development of plants, increased the productivity of tomatoes in the acutely arid conditions of the Lower Volga region. The object of the study was the tomato variety Hercules. The highest yield of tomatoes with the formation of a large number of large fruits with good taste indicators was obtained on the variety Hercules on the variant with pre-sowing seed treatment, as well as non-root treatment of plants in the initial growth period and in the budding-flowering phase. The use of the Energy-M growth regulator on tomato culture is an effective measure. It is recommended that producers of high-quality vegetable products widely use this drug against the background of sufficient mineral nutrition by soaking the seeds before sowing and processing the plant throughout the growing season.

The article considers the results of research on the influence of seeding rates, fertilizers and growth stimulator on the development and productivity of the Sudan grass of the Julia variety in the conditions of chestnut soils of the Volgograd region. In the field two-factor experiment, we studied: factor A - the three seeding rates 1.0, 1.5 and 2.0 million germinating seeds per hectare; factor B - fertilizers and growth promoters: 1. Control without fertilizers; 2. N60 P60 K45 + N30; 3. Growth stimulator Raikat Start; 4. N60 P60 K45 + Raikat Start + N30. The use of mineral fertilizers increased the leaf surface area by 0.3-0.5 thousand m2/ha, the use of growth stimulators increased the leaf surface area by 0.1-0.2 thousand m2/ha, the combined use of mineral fertilizers and growth stimulators increased the leaf surface area by 0.9-1.2 thousand m2/ha. It was found that the highest yield of green mass of Sudan grass, 28.6 t/ha, was formed on the variant with a seeding norm of 1.5 million tons of germinating seeds per ha with the complex application of mineral fertilizers and the growth stimulator Raikat Start.

Abstracts. The years of experiment were from 2016…2020 in a farm on the Ergenin Upland chestnut soils in Volgograd region. The experiments were placed in five fields of vegetable crop rotation with the total area of 165 ha. During the presented period, a competitive test was carried out to identify the most productive samples of onions. The objects of the study were samples -the zoned variety Volgodonets (control variety) of domestic selection, hybrids of foreign selection Pandero F1, Benefit F1, Valero F1, Manas F1. It was found that hybrids give more than twice the yield over the control variety in almost all the variants. But the most optimal and more productive in all cases proved to be option No. 2 hybrid Benefit F1 with the parameters: the seeding rate of 1,000,000 pcs of seeds per hectare with viability of 97.31%, which provided for harvesting 973,100 plants per hectare and achieved a yield of 143.41 t/ha on average for repetitions in 2020. Thus, we can conclude that the seeding rate is 1,000,000 pcs of seeds per hectare in the conditions of chestnut soils of the Ergenin Upland is optimal in the conditions of the existing agricultural technology.

Currently using the system Clearfield combined with other technologies of cultivation, given the state of the fields, soil and climatic conditions, the availability of soil mineral nutrients is a promising direction in the cultivation of sunflower in the Lower Volga region. In this regard, the experience of studying various technologies of cultivation for sunflower hybrids was laid on ordinary chernozems. The highest biological yield on average for 2015-2017 was created in the hybrid Mowgli with the herbicide Eurolighting fungicide Pictor with the introduction of liquid complex fertilizer in the phase of 2-4 leaves at the rate of 120 l/ha. On average, it was 2.57 t/ha in terms of repetitions. The lowest biological yield of sunflower was obtained from the Bosphorus hybrid with the herbicide Gezagard and the fungicide Thanos without the use of mineral fertilizers and was 1.61 t/ha. According to the factor B “Mineral fertilizers” in the control variants the average yield was 1.55 t/ha. In the variants with the introduction of NP (12:52) 80 kg/ha of ammophos, the average yield was 1.99 t/ha. In the variants with spraying in the phase of 5-6 leaves of liquid complex fertilizer NP (11:37) 120 l/ha, the average yield was 2.13 t/ha.

The experiment is carried out in the conditions of semi-desert flat agricultural landscapes of light chestnut soils. The object of research is a 4-field crop rotation (factor A), variants of the main tillage (factor B) and crops superimposed on the tillage options with the Don-114 seeder (a seeder for direct sowing). The placement of options (A) is sequential and options (B) are arranged in blocks in three tiers. The main soil tillage was carried out by the following tools: mouldboard tillage to the depth of 25-27 cm by plough PN-4-35; non-mouldboard tillage to the depth of 25-27 cm by the tool OCHO-5-40 with the rack “Rancho”; surface one to the depth of 8-10 cm by the tool BDM-4.2, and 4-field grain-fallow crop It was found that a higher content of nutrients is in fallow preferably at non-mouldboard soil treatment, in some years, which has an optimal moisture supply, and control (mouldboard) one in comparison with lower levels of surface soil treatment in all years of the research. The main comparison in the change in nutrients in fallow fields is observed precisely for different methods of soil cultivation.

The aim of the research was to study the sodium selenite using various methods effect on the yield and quality of Degas variety white lupine grain. To solve these issues microfield experiment on the experimental plot of the Department of agronomic, biological chemistry and radiology of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy was carried out. Thus, it was found that the use of sodium selenite for foliar treatment of plants contributed to the greatest increase in the yield of white lupine plants. The increase in the grain yield of 27% compared to the control was obtained. The increase in the weight of the beans was revealed by almost 2 times. This indicates the influence of sodium selenite on the processes of fruit formation and the process of laying the seed productivity of lupine plants. The greatest effect of foliar treatment of plants with sodium selenite was found. In this variant, the largest increase in grain yield and the highest content of crude protein in the lupine grain were obtained. It is concluded that the use of selenium affects the formation of beans and grains in them, which determines the increase in plant yield.
