Authors: Stepochkin P. I. , Gordeeva E. I. , Khlestkina Е. K. 
Published: July 2023

Background. Cereals whose grain contains antioxidants salutary for human health are promising for functional nutrition. Anthocyanins inducing purple grain color are antioxidants, and it is crucial to make efforts towards increasing their content in grain. The objective of this work was to assess the content of anthocyanins in emmer grain and the productivity of breeding lines with purple grain. Materials and methods. The study included the F9 lines developed by two-step hybridization between purple-colored Ethiopian wheat (Triticum aethiopicum Jakubz. var. arraseita) and emmer (Triticum dicoccon (Schrank) Schuebl.), and those isolated in F2 using marker-based selection for homozygous dominant alleles of two genes. The parent forms of the hybrids were a naked-grain emmer cultivar ‘Gremme’, an awnless emmer accession (k-25516) from the VIR collection, and an accession from the collection of IPK Gatersleben (Ethiopian wheat line TRI 15744), the donor of the purple color. The content of anthocyanins in whole-grain flour was measured in 12 lines, a structural analysis of plants was carried out, and their quantitative characteristics were assessed. Results. The highest anthocyanin content (82.5 µg per 1 g) was observed in line No. 10 of the 27-3 hybrid. The largest share of threshed naked grains (86.9 ± 7.3 %) was recorded for line No. 6 of the 31-19 hybrid. Line No. 11 of the 27-12 hybrid had the highest test weight (802 ± 13 g/L). Line No. 9 of the 27-1 hybrid showed the best index of grain productivity (389 ± 25 g/m2). Conclusion. Marker-assisted selection made it possible to identify homozygous dominant alleles of the two complementary interacting genes, Pp3 and Pp-B1, which cause the purple color of the grain pericarp. Breeding lines with purple-colored grain demonstrated different levels of the total anthocyanin content, test weight, and grain yield. The lines with high indices of these traits are valuable for breeding practice.

Authors: Gumerova G. R. , Galimova A. A. , Kuluev B. R. 
Published: July 2023

Background. Bread wheat (Triticum aestivum L.) is one of the staple cereal crops, so it is of great interest to breeders and researchers and requires constant monitoring of existing cultivars, including the development of new ones through classical breeding and modern gene engineering. The key stage in these techniques is successful callusogenesis and organogenesis intarget objects. With this in view, the regeneration potential of two spring (‘Saratovskaya 55’ and ‘Sigma’) and three winter (‘Tanya’, ‘Fisht’ and ‘Pamyat’) cultivars of bread wheat was assessed, and optimal conditions were identified for callus induction and organogenesis using mature embryos. Materials and methods. Immature and mature embryos of the five bread wheat cultivars were used in the study. The in vitro morphogenetic potential was evaluated under the impact of abiotic factors: preliminary exposure of grains to cold and use of exogenous hormones (2,4-D in various concentrations). Pretreatment of wheat with cold was carried out as follows: sterilized grains were incubated on the hormonal medium at a temperature of 4 °C for 2 weeks, and then transferred to 26 °C for 4 more weeks. The efficiency of callusogenesis and rhizogenesis was assessed and the numbers of morphogenetic calluses, regenerated and acclimatized plants were calculated. Results and conclusions. The analysis made it possible to identify the bread wheat cultivars ‘Fisht’ and ‘Sigma’ for their high morphogenetic and regenerative potential. It was also shown that exposure to cold can serve as a good stimulating factor for producing a large number of calluses, but regenerants are better induced under normal conditions. The results also depended on the concentration of hormones applied. Universal conditions for morphogenesis and regeneration were not identified.
Higher stability of oat, barley and wheat accessions in their 1000 grain weight is not associated with a smaller grain size
Authors: Polonsky V. I. , Sumina A. V. , Gerasimov S. A. , Kolichenko A. A. 
Published: July 2023

Background. It is important and relevant to know whether the selection among cultivars for increased stability in the weight of 1000 grains involves a significant change in grain size. The aim of the study was to analyze the relationship between the 1000 grain weight in oat, barley and wheat accessions, on the one hand, and their adaptability indicators for this trait, on the other. Material and methods. The studied material included 10 cultivars of oat, 12 of barley, and 11 of wheat from the VIR collection. Plants were grown in 2021 at five different sites over Eastern Siberia (Krasnoyarsk Territory, and the Republic of Khakassia and Tyva). After harvesting, the weight of 1000 grains was measured for each cultivar. The coefficient of environmental variation (Cv), stress tolerance index (d), homeostasis parameter (Hom), stability level index (CSL), and breeding value index (Cs) were determined to assess the cultivars for the analyzed character. Results. Oat cultivars exhibited significantly lower plasticity and higher stability in their 1000 grain weight. The best adaptability characteristics were recorded for oat cvs. ‘Argument’ and ‘Kross’, barley cvs. ‘Krasnoyarsky 91’ and ‘Biom’, and wheat cvs. ‘Novosibirskaya 49’ and ‘Novosibirskaya 75’. Cvs. ‘Kross’ and ‘Argument’ (oat). and ‘Biom’ (barley) had the largest grain size and maximum values of the character’s stability parameters. Correlations of oat and wheat grain size with both plasticity indices were negative, and positive with all stability parameters, being significant for CSL and Cs. In the case of barley cultivars, the correlation between the weight of 1000 grains and the plasticity index was negative and statistically significant. Conclusion. The results demonstrate that when selecting oat, barley and wheat for increased stability of their 1000 grain weight, the grain size will not decrease. Moreover, it may have a tendency to increase.
The effectiveness of using some criteria for determining adaptability on the example of winter rye cultivars
Authors: Safonova I. V. , Aniskov N. I. 
Published: July 2023

Background. For most regions of Russia, winter rye is an indispensable grain and fodder cereal. Recently, winter rye crops have been declining. It is possible to improve this situation by releasing cultivars that ensure consistently high grain productivity under various growing conditions. Therefore, measuring the level of adaptability for yields in different mathematical quantities using a variety of methods is an urgent need. Materials and methods. For an unprejudiced assessment of winter rye cultivars, the following adaptability parameters were calculated and analyzed: the intensity coefficient (I) and constancy of the stability index (Y) according to Udachin and Golovchenko; stability index (IS) according to Hangildin; range breadth (Jsp) according to Eberhart and Russell; breeding value (Sc) according to Hangildin; responsiveness coefficient (Cr.) according to Zykin; genotypic effect (Ɛi) according to Guryev; equalization coefficient (B) according to Dospekhov; multiplicativity coefficient (KM) according to Dragavtsev; and reaction effect (Er.) according to Novokhatin. Field experiments and the study of 8 winter rye cultivars were carried out according to VIR’s guidelines in 2012–2017. Results and conclusion. A significant variation was found in grain yield; it was induced by the high contribution of the “year” factor (79.4 %). The best conditions for higher yields were formed in 2012 and 2015. An analysis of the six-year average yield showed that cvs. ‘Rushnik 2’, ‘Bereginya’, and ‘Novaya Era’ exceeded ‘Ilmen’ by 5–22 %. It was shown that among the selected ten indicators, worth attention were the multiplicativity coefficient, the stability index, the breeding value index, the reaction effect of a cultivars, and the range breadth index: they established the adaptability level of a cultivar with higher statistical significance. Cvs. ‘Novaya Era’, ‘Yanrarnaya, ‘Bereginya’, and ‘Vavilovskaya’ from the analyzed set demonstrated high adaptability.

Published: July 2023

Studying plants of the wheatgrass genus as a unique and valuable fodder and phytomeliorating perennial arid xerophytic crop is of great interest to plant breeders, geneticists, biologists, ecologists, agriculturists, and forestry experts in southern regions of Russia, the ex-USSR republics, a number of European and Asia Minor countries, the U. S., Canada, and China. Accessions from the VIR collection representing five wheatgrass species were studied for the first time under the harsh conditions of extremely continental climate in the northern region of Central Yakutia. Introducing wheatgrass, widespread in this region, into cultivation, and releasing new cultivars adapted to local conditions are urgent tasks in forage production. Agropyron Gaertn. incorporates polyploid series, which expands the possibilities of using its accessions in hybridization. The aim of this study was to analyze and select promising accessions as sources for further use in breeding practice to develop a new cultivar for hay and pasture purposes, and identify genotypes with the best agronomic characteristics. Results of a three-year (2018–2020) study involving 22 wheatgrass accessions of various ecogeographic origin are presented. The accessions identified over a two-year period for their average yield of green fodder biomass were k-52382 (143.7 g/plant) from Pavlodar Region of Kazakhstan, and the Kazakh cultivar ‘Batyr’ (142.5 g/plant); for the yield of dry fodder biomass, crested wheatgrass k-52382 (on average 65.8 g/plant), k-51330 from Chelyabinsk Province (56.1 g/plant), and cv. ‘Batyr’ (53.2 g/plant); for high seed yield, Siberian wheatgrass accession k-52440 (28.4 g/m2), wild crested wheatgrass k-51330 (25.2 g/m2) and k-52380 (19.4 g/m2), and Kerch wheatgrass k-48705 (17.3 g/m2). Nutrients and energy in the tested accessions were assessed.

Published: July 2023

Problem. The most high-precision parts of the car engine are camshaft and crankshaft, parts that require two-sided processing of the end surfaces: piston pins, valve springs. Traditional processing methods are used in their manufacture and repair. Therefore, taking into account the large volumes of car production, the improvement of existing and development of new processing methods is very important. Goal. The purpose of this work is the analysis and improvement of existing methods and the implementation for new ones of processing the specified parts to increase the productivity and accuracy of their processing. Methodology. The processing of support necks and cams is expedient to be carried out in one installation during deep high-speed grinding with crossed axes of the circle and camshaft due to stabilization of the cutting depth and feed along the contour with uneven rotation of the part. The method of high-speed milling of camshaft cams with crossed axes of the tool and parts on CNC machines is also promising. Root and connecting rod necks of crankshafts can be processed in one installation by deep high-speed grinding with crossed axes of the circle and the part due to stabilization of the depth of cutting and feed along the contour with uniform rotation of the part. For end surfaces, it is possible to introduce single-pass processing on double-sided end grinding machines with oriented grinding wheels with calibration areas. Results. The obtained results indicate a 25-30% increase in productivity and processing accuracy of the specified parts. Originality. It is used when processing the effect of the intersection of the axes of the tool and the part and carrying out a special correction of the tool, which allows to obtain a calibration area. Practical value. The proposed methods improve the parameters of accuracy, roughness and productivity of processing, which is an important scientific and practical task, whose solution will allow to increase the service life of car components and assemblies, reduce the cost of their production, and raise the level of competitiveness of products and services.

Authors: Riabushenko Oleksandr 
Published: July 2023

Problem. The article considers the issue of determining the location of "bottlenecks" on the highways of large cities based on the study of the vehicle's driving mode, obtained as a result of GPS data processing and analysis. Purpose. The purpose of this study is to develop and test the methodology for identifying potential "bottlenecks" on the city's freeway by analyzing the GPS track data of the car. The subject of the study is the interrelationship of the characteristics of the sections of the city’s street-road network (SRN) with the parameters characterizing the vehicle movement mode in the traffic flow. Methodology. Two experimental routes with the same starting and ending points were chosen to obtain data on traffic conditions on the SRN of the city of Kharkiv, which correspond to typical routes of official movement of personal transport on weekdays. During the movement of the car along the specified routes, GPS tracks were obtained, whose processing made it possible to determine the driving conditions along the entire length of the routes. Results. The work presents a method of researching the vehicle's driving mode by analyzing GPS track data; the determined indicators of the traffic regime, which can be effectively used as criteria for determining potential "bottlenecks" on the city's SRN; the methodology was tested on real traffic routes on the SRN of the city of Kharkiv. For selected routes, the work presents histograms of instantaneous speed distribution, graphs of car movement in "distance - speed" and "time - speed" coordinates. Graphs of changes in specific time in motion, specific idle time, speed gradient, energy gradient, Hermann-Prygozhin criterion were obtained for individual kilometer segments of routes. The specific idle time and the Herman-Prygozhin criterion turned out to be the most effective criteria for the purposes of determining the "bottlenecks" of SRN. Originality. An experimental technique was developed and tested, which allows to determine the potential "bottlenecks" of the city's SRN as a result of conducting short-term and not labor-intensive research. The proposed approach does not require the presence of specialized equipment or software, which makes this method effective when conducting scientific research. Practical value. The possibility of using the proposed method of data processing of GPS tracks to analyze traffic conditions on the city highway and identify potential "bottlenecks" was shown. For the selected routes in Kharkiv, such sections turned out to be Vesnina St. (beyond the intersection with Pushkinska St.); Heroes of Stalingrad Ave. (access to the intersection from Leva Landau Ave.); Gagarina Ave. (access to the intersection with Kashtanova St.)
A review of the automated guided vehicle systems: dispatching systems and navigation concept
Authors: Siegfried Patrick , Bourafa Rami 
Published: July 2023

Problem. As one of the three key elements of flexible manufacturing systems (FMS), automated guided vehicles (AGVs) play a significant role in material handling systems. They've been around for more than a decade, primarily in Europe. AGVs were formerly utilized mostly in production lines, but due to recent industrial development, they now play a vital role in a variety of different applications and domains, including warehouses, port facilities, transportation systems, and even the medical sector. Goal. The purpose of the work is to analyze two methods of AGV control and the paths that the AGV should follow during transport operations, taking into account safety and limitations for heavy loads that need to be transported in difficult conditions. Methodology. We attempted to provide a summary of the two existing AGV control methods, centralized and decentralized control offered by major manufacturers in this study. Almost all function in a centralized manner, with a single central controller controlling the whole fleet of AGVs. The author sees a tendency toward decentralized systems in which AGVs make individual decisions in favor of transportation flexibility, robustness, and adaptability. A brief explanation of well-known and mature navigation technologies used by AGVs in the industry is also provided, along with both physical and virtual paths to be followed by the AGV during transportation operations, since these technologies get to be a key issue given the safety constraints, particularly for heavy loads to be transported in challenging environments. Results. This paper covers one of the key tasks that must be completed in order to control an AGV system for a central and decentral architecture, for which we have already given a broad overview, as well as the differences between the architectures and their benefits and drawbacks. Originality. The author sees that the merging of various techniques we have will lead to more and new challenges as well as innovations, however, that practical application of distributed control still requires further research and studies and has a way to go in terms of taking other sections such as safety and sustainability into account. Practical value. The primary benefits and drawbacks of various technologies are discussed, as well as how we might improve the efficiency of some of them.

The aim of this research was to evaluate the use of lemuru fish oil as palm oil substitution in ration on broiler performance. This research used 200 Ross broilers day old chick (DOC) is divided into 4 treatments and 5 replications. This research used a completely randomized design (CRD), where the treatments level of palm oil and lemuru fish oil were respectively P0 = rations containing 3% palm oil and 0% lemuru fish oil, P1 = rations containing 2% palm oil and 1% lemuru fish oil, P2 = rations containing 1% palm oil and 2% lemuru fish oil, P3 = rations containing 0% palm oil and 3% lemuru fish oil. The variables observed were feed intake, final body weight, body weight gain, feed conversion ratio (FCR), mortality, and income over feed and chick cost (IOFCC). The data were analyzed using analysis of variance (ANOVA). The significant result (P<0,05) were followed by Duncan test. The results showed a significant effect (P<0.05) in decreasing FCR in the starter period with a higher level of use of lemuru fish oil, increasing body weight gain and decreasing FCR in the finisher period with a lower level of use of lemuru fish oil, but the treatments did not significantly effect on performance broiler during the age of 35 days. Weight and percentage of internal organs and digestive tract under normal conditions, except liver weight.
The conclusion of this study was the use of 3% lemuru fish oil can improve FCR in the starter phase, but the different level of palm oil and lemuru fish oil until 3 % in broiler rations does not affect on broiler performance during the age of 35 days.
Truman y el padre corporativo
Authors: Fuentes Lenci ´Álvaro 
Published: July 2023

En ocasión del 25 aniversario de The Truman Show, este texto se propone revisitar la película de Peter Weir (1998) a partir de dos fuentes principales: “Mar abierto (un horizonte en quiebra)” de Juan Jorge Michel Fariña, artículo publicado al año del estreno de la película (1999), y Padres en el cine, Películas en interlocución (2022), el último libro de Eduardo Laso. Mediante la primera fuente, se busca profundizar en la comparación de las figuras paternas de Truman (el padre corporativo que es Christof y el padre farsante que le asigna el Reality Show) con los padres de bebés apropiados en la dictadura militar de 1976, entendiendo que ambos son vínculos que se basan en la falsificación de la identidad. Se aporta un concepto de superyó de escala corporativa, haciendo ingresar herramientas de psicología de grupos y tipología de los padres; esto último con la ayuda de la segunda fuente mencionada. Volver a pensar The Truman Show es tomar el desafío de actualizarla, desprendiendo conclusiones acerca del tipo de relación que emisores y receptores de la información establecen bajo la escena comunicacional del presente; porque un clásico es una película que no pierde relevancia a pesar del paso del tiempo.
