Authors: Shepitko T. V. , Lutsky S. Ya. , Artyushenko I. A. 
Published: January 2025

The study outlines the technology for increasing the bearing capacity of the subgrade foundation on high-temperature permafrost soils in the Arctic zone with the objective to develop technological regimes for strengthening the weak foundation of embankments, allowing for regulation of loads during construction of facilities on permafrost soils. The research methods included system analysis and the methods specific for organising construction in the permafrost zone. The described methodology consists of step-by-step modelling and calculation of parameters for geotechnical monitoring of the condition of the subgrade to determine the maximum permissible technological loads.The tasks and functions of the system for regulating and monitoring technological operations are determined to specifically increase the strength characteristics of weak foundations during the construction period. The main factors influencing functioning of a new natural-technical complex during construction on permafrost have been established, namely changes in the temperature field, loads of construction machines and physical and mechanical characteristics of soils. The study highlights feasibility of organising comprehensive assessments and mutual control of soil deformability using geotechnical monitoring and automated process control systems for machines and construction equipment. The technological regime for deep strengthening of weak foundations of geotechnical objects should include regulation of the parameters of construction loads and quality control of processes during vibration compaction of the upper zone and construction of a pile field.The article outlines the features of the experimental application of the complex technology to ensure the design bearing capacity of soils during reconstruction and construction of sections of the Northern Latitudinal Railway and Obskaya – Bovanenkovo railway.

Authors: Rada A. O. , Konkov N. Yu. 
Published: January 2025

Motorways are a strategically important part of a country’s infrastructure. High requirements for their condition stipulate regular monitoring of quality of the road surface. The large length of motorways in Russia and the impact of weather and climate conditions (seasonal temperature fluctuations, precipitation) emphasise the relevance of searching for non-destructive testing methods for road diagnostics that ensure short terms of diagnostic work and the use of minimal resources.The considered existing solutions for detecting road surface damage include the use of ground penetrating radar, laser method, method of analysing vibration effects of road surface irregularities, detection of damage based on lidar data and mobile mapping systems.The objective of the study was to develop an algorithm for analysing the condition of the road surface that allows detecting road surface distresses based on images obtained during the diagnostics of motorways by the KP-514-RDT airfield and road measuring mobile laboratory completed by the IndorRoad and RDT-Line software packages.The development of an algorithm for detecting road surface defects was carried out using machine learning methods. The detected defects have precise georeferencing according to stationing of the measured road segment. As a result of development, a trained model was obtained that allows automatic marking of defects of different classes on the image. The developed algorithm is integrated into the software for managing the monitoring of the condition of regional and municipal roads.

Published: January 2025

The study considers the issue of increasing traction properties of freight locomotives under the conditions of the Eastern Polygon, the eastern part of the Russian railway network. The analysis results have allowed identifying design factors influencing the adhesion properties of locomotive and suggesting an extended classification of methods for improving the adhesion properties by selecting rational design solutions for the undercarriage.It is established that for unified three-axle bogies of domestic freight diesel locomotives, the factors leading to a decrease in the adhesion coefficient in operation include a significant base length, unbalanced spring suspension and insufficient rigidity of the body supports resting on the bogie with the upper location of the kingpin, while for bogies of electric locomotives with brushless traction electric motors they include a rigid connection of the engine rotor with the wheelset, leading to the occurrence of high dynamic torques. It is proposed to use balanced pneumatic spring suspension and increase the rigidity of rubber-metal supports as measures for modernisation of diesel locomotive bogies, and for the prospective unified undercarriage of diesel and electric locomotives – to refuse from placing the fuel tank under the body and to use two-axle bogies with a frame-support traction drive with an axial gearbox, or with an axle-support drive of the aggregate type, having an elastic coupling, damping dynamic loads. The obtained results give grounds to believe that these measures will increase the coefficient of adhesion during operation from 0,27 to 0,3… 0,33.

Published: January 2025

The main activity of peasants in the Valle de Conlara is cattle grazing in degraded native forests. In similar regions, excluding cattle during rainy seasons allows for better conditions of the herbaceous layer and soil in forests. Complementary use of implanted pastures makes this possible. The objective was to evaluate the effects of seasonal exclosure (vs. continuous) and complementary use of an exotic pasture, on forage biomass and quality, and soils. For two years, wet (842 mm/year) and dry (521 mm/year), three plots with a different treatment were monitored: forest with six years of summer exclosure, forest without exclosure, and Panicum coloratum pasture on a cleared site. The plot with exclosures vs. without exclosures had 2.5 times more native grass cover, 1.9 to 3.4 times more Aboveground Net Primary Production (dry and wet years, respectively), and four times more seed bank density. The soil had greater litter cover and infiltration capacity, lesser bare soil area, and higher percentage of C, P and N. The productivity of P. coloratum doubled native grasses in the rested forest. Using it during summer, allows the herbaceaous layer of the forest to rest and defers it towards the winter, maintaning better quality than the pasture.

Published: January 2025

In the Frailesca region of Chiapas, Mexico, conventional sorghum (Sorghum bicolor) production has decreased soil fertility, primarily by reducing its organic matter. This makes it necessary to look for alternatives to increase its yield, since it is an important cereal for animal feed. This study aimed to evaluate the agronomic and productive response of sorghum to the application of three doses of compost. It was conducted during the spring-summer 2018 agricultural cycle, under rainfed conditions in the municipality of Villaflores, Chiapas, Mexico. The treatments were a control and three doses of compost (10, 20 and, 30 t/ha-1), incorporated into the soil before planting. Four experimental plots per treatment were established using a completely randomized design. The response variables were agronomic and productive, and they were evaluated using analysis of variance and a mean comparison test. Both the agronomic parameters (plant height, stem thickness and biomass fresh weight) and the productive parameters (grain weight and yield, panicle length and weight) were statistically superior in the 20 and 30 t/ha-1 compost treatments compared to the 10 t/ha-1 treatment and the control.

Published: January 2025

The study evaluated the impact of fungicide programs (FPs) on disease control in soybean during the 2021/2022 season in La Paloma, Katueté and Nueva Esperanza (Canindeyú, Paraguay). The area under the disease progress curve (AUDPC) was evaluated for the predominant diseases, defoliation, and yield. In addition, the control efficacy (CE) and the reduction in productivity (RP) were calculated. Variance analysis was conducted on factors FP, Location, and their interaction, using Tukey’s test at a 5 % error level for mean comparisons. Target spot (TS) and Cercospora leaf blight (CLB) were the predominant diseases in all locations. Asian soybean rust (ASR) occurred only in Nueva Esperanza and Katueté. FPs reduced AUDPC up to 64, 85 and 73 %, on average, for TS, ASR and CLB, respectively, leading to increased yield, on average, between 9 and 27 %, compared to the control. La Paloma achieved the highest yield (4651 kg ha-1) and lower defoliation (61 %), followed by Katueté (4330 kg ha-1 with 70 % of defoliation), and Nueva Esperanza (3739 kg ha-1 with 86 % of defoliation). This study provides strategies to optimize fungicide use in soybean management in Paraguay, highlighting sequential applications and rotation of modes of action.
Implementation of a method for the identification and quantification of phytosterols in peanut (<i>Arachis hypogaea</i> L.) by gas chromatography
Authors: Aquilano Claudio Gabriel , Percibaldi Nora Mabel , Martínez María José 
Published: January 2025

Peanut (Arachis hypogaea L.), a major source of oil, is the second most widely cultivated legume crop worldwide after soybean. Argentina is the largest producer of confectionery peanuts in Latin America and the seventh in the world. This legume has bioactive compounds of nutritional value, phytosterols among the most important ones. Phytosterols protect against cancer and lower cholesterol rates. The objective of this work was to adjust and refine a method to identify and quantify phytosterol content in peanut seeds by gas chromatography. The method was found to be accurate, as demonstrated through repeatability and reproducibility tests, and expressed by the coefficients of variation. No significant differences were found between the results obtained and the reference values using a confidence level of 95 % and 5 degrees of freedom. The results obtained in this work presented 44.31 mg of beta-sitosterol and 3.39 mg of stigmasterol per 100 g of roasted peanuts, in agreement with the values reported in the literature.

Lettuce is cultivated on over one million hectares worldwide, with Argentina contributing 40,000 ha. Córdoba province is the second-largest producer in Argentina, but its green belt has seen significant reductions in cultivated areas. New environmentally friendly technologies are needed to improve, sustain and increase lettuce volume production. This study aimed to use plant growth-promoting rhizobacteria (PGPR) as a sustainable alternative to enhance lettuce production (Lactuca sativa L.) growth while mitigating environmental impact. Two PGPR strains, Bacillus velezensis RI3 and Pseudomonas psychrophila P10, were tested in both in vitro and field experiments. Parameters such as shoot dry weight, root dry weight, evapotranspiration, and water use efficiency were assessed. The in vitro study results demonstrated significant improvements in shoot and root dry weights for both inoculated treatments compared to the control. Field experiments, conducted on 90 m² plots, also demonstrated significant increases in shoot dry weight, with Pseudomonas psychrophila showing a 28.57 % increase and Bacillus velezensis a 8.44 % increase compared to controls. This study highlights the potential of Bacillus velezensis and Pseudomonas psychrophila as effective biofertilizers, promoting sustainable lettuce cultivation. Further research is recommended to explore the mechanisms of plant-microbe interactions to optimize PGPR application in agricultural practices.
ЧИ КАРБУВАЛИ МОНЕТИ ДАНСЬКІ ХЕРСІРИ В СЕРЕДИНІ ХІ СТОЛІТТЯ?
Authors: Kuleshov Serhii 
Published: January 2025

Ця розвідка продовжує спроби автора щодо висвітлення питання обігу в середньовічній Україні денаріїв різних європейських країн. Мета статті полягає в намаганнях автора здійснити атрибуцію середньовічного денарія, знайденого у Київській області. Методологія дослідження. Застосовано методи історизму, узагальнення, об’єктивності, історико-типологічний, порівняльного аналізу. Наукова новизна. На підставі аналізу зображень та напису на аверсі монети автор приходить до висновку, що дена рій становить наслідування англійського пенні короля Кнуда Великого типу «Короткий хрест». Пошук аналогів зображень реверса дав змогу зробити висновок, що монета частково наслідує один вид денарія, що карбував Кнуд як данський король у місті Віборг (Центральна Ютландія). Однак аналогічної монети у наявних каталогах автором не знайдено.Висновки. Характерними ознаками, що відрізняють знайдений денарій,стали його вага,яка відповідна номіналу у пів денарія, та відсутність монети у каталогах і знахідках, що свідчить про суттєво обмежену кількість його випуску. Автор припускає, що його емітентом міг бути у Центральній Ютландії місцевий херсір (ярл, бонд), а час карбування міг припадати на так званий Stridsperioden (Civil War), cрідсперіоден» (що буквально означає «час суперечок») – так данські історики називають період, коли данські та норвезькі претенденти (Магнус Добрий, Гаральд Суворий, Свен Естрідсен) боролися за данський престол. У цей період, близько 1044–1047 рр., різні емітенти карбували монети-наслідування зі спотвореними написами або монети попередніх правителів. Це робилося для того, щоб не виказувати свою прихильність до жодного із претендентів, а такожз метою відрізнити її від цього офіційного карбування,вага монети – це, фактично, вага половини денарія. Водночас, на приналежність до наслідування монет Віборга вказують публікації данських нумізматів щодо пізнішого повторення означеного реверсу на монетах Свена Естрідсена. Хоча випуски деяких цих денаріїв міг здійснювати Свен Естрідсен під час боротьби за данський престол.
ШАГИ – ПАПЕРОВІ РОЗМІННІ МОНЕТИ ДОБИ УКРАЇНСЬКОЇ РЕВОЛЮЦІЇ 1917–1921 РОКІВ
Authors: Levchenko Larysa 
Published: January 2025

Анотація.2024 року Національним банком України в контексті декомунізації та відновлення історичної справедливості ініційовано заміну розмінної монети «копійки» на «шаг». У цьому контексті набуло актуальності обґрунтування належності «шагів» до традиційної української грошової системи. Мета цієї публікації полягає у дослідженні історії розмінної монети «шаг» доби Української революції 1917–1921 рр. за архівними документами, виявленими в Центральному державному архіві вищих органів влади та управління України (ЦДАВО України), тексти яких у переважній більшості вперше запроваджено до наукового обігу і вміщено в додатку. Методологія дослідження включає як загальнонаукові, так і спеціальні методи.
Аналіз попередніх досліджень показав, що монети «шаги» перебували в обігу на українських теренах з 1528 по 1725 рр. і були скасовані під час грошових реформ Петра І.
«Шаги» відродилися в Українській Народній Республіці у складі гривневої грошової системи: одна гривня поділялася на сто шагів. Специфікою цієї монети був її випуск не з металу, а на папері у вигляді марок. Запроваджувати в обіг «марки-шаги» було розпочато за Української Держави Павла Скоропадського та продовжилося за Директорії УНР. Як свідчать архівні документи, за період від 1917 р. до лютого 1922 р. у різних експедиціях в Києві, Одесі, Кам’янці-Подільському, Станіславові було надруковано марок-шагів на суму 46.306.555 гривень, в обіг для населенняїх випущено на суму 46.165.973 гривні. Шаги перебували в обігові як на території Української Народної Республіки, так і в дещо меншому обсязі на території Західноукраїнської Народної Республіки.
Більшовики після окупації Києва (березень 1919 р.) вилучали з обігу марки-шаги з усіх банків, установ, підприємств та організацій. Анулювання українських марок-шагів найсильніше вдарило по кишені найбідніших прошарків населення, яким уже за радянської окупації «шагами» видавали зарплату.
В Українській Народній Республіці та Українській Державі шаги відігравали значну роль ще й при встановленні процентних ставок, курсу валют, оплаті поштових послуг та в інших розрахункових операціях.
Таким чином, «шаги» за часів Української революції 1917–1921 рр. дійсно були суттєвою складовою грошового обігу та української монетної системи, тому їхнє відродженняабсолютно закономірнета історично справедливе.
