Authors: Hasparyk Nicole Pagan , Torres Sandro Marden , Tiecher Francieli , Amantino Guilherme , de Souza Wesley Maciel
Published: April 2023

The behaviour of concretes with and without rice husk ash was experimentally investigated with respect to the susceptibility to delayed ettringite formation. Concrete specimens have previously undergone a specific initial thermal curing up to 85°C, which was designed to trigger delayed ettringite formation. Specimens were subsequently exposed to a specific exposure environment by water immersion at 38°C, over 1 year. Expansion measurements and microstructural analyses were performed to evaluate the level of attack, as well as the integrity of concretes and chemical characteristics of compounds by means of SEM-EDS. Mechanical properties were also assessed over one year to detect the level of damage from delayed ettringite formation. The data has indicated that the incorporation of 8% of rice husk ash could partially reduce the level of DEF expansion and damage. The microstructure of cement matrices from both the reference and RHA concrete indicated different features, sulfate phase compositions and degradation stages. The reference concrete contained radial cracking from filled pores and nearby interfacial transition zone, whereas RHA concrete presented denser features, with microcracking scattered at random across cement matrix and minor neoformations.
Flake-shaped ZnFe2O4 nanoparticles: synthesis, characterisation and photocatalytic study
Authors: Dhal Jyoti Prakash , Sahoo Amit , Acharya Achyuta Nanda
Published: April 2023

Flake-shaped franklinite (ZnFe2O4) nanoparticles were successfully prepared by using the co-precipitation method. The phase and crystallinity of the synthesised franklinite nanoparticles were studied by X-ray diffraction. The scanning electron microscopy results revealed that the flake-shaped entities were formed in combination with rod-shaped nanomaterial. The band gap of the synthesised franklinite nanoparticles was found to be ∼2.14 eV by ultraviolet–visible diffuse reflectance spectroscopy measurements, indicating that this material absorbs visible light (λ max = 579.37 nm). The ferrite nanoparticles were successfully employed as a photocatalytic material for the degradation of the dye malachite green in an aqueous medium with ∼99% efficiency under visible light irradiation.
Effect of saturation confining pressure on accessible density and shear behaviour of sandy silt tailings
Authors: Reid D. , Urbina F. , Tiwari B. , Fanni R. , Smith K. , Fourie A.
Published: April 2023

Significant reduction in the brittleness of sandy silt/silty sand tailings at high stresses has frequently been observed in laboratory element testing due to curvature of the critical state line and the limiting compression curve. This has led to discussions regarding the range of effective stresses across which such materials can exhibit brittle undrained shearing such that flow liquefaction could occur. However, much testing of such tailings appears to involve saturation of the tailings under relatively low-confining stresses. This differs from the potential in situ loading within a filtered tailings stack, where material placed in a loose, unsaturated state may be subjected to significant overburden pressures prior to potential subsequent saturation. A series of isotropically consolidated triaxial tests were carried out on sandy silt gold tailings to investigate the effects of the saturation process of loose moist-tamped specimens occurring at different confining stresses. The tests indicated much looser states were achievable when saturation occurred at higher confining pressures, with resulting undrained shearing for such specimens being of similar magnitudes of brittleness as observed in flow liquefaction case histories. Consideration of saturation overburden pressure of filtered tailings stacks therefore appears warranted.

Una mirada antropológica a la reforma policial uruguaya y su ocaso
Authors: Del Castillo Federico
Published: April 2023

¿Por qué fracasa una reforma policial? La literatura sobre políticas públicas nos suele proponer respuestas racionalistas y cientificistas a este tipo de preguntas, frecuentemente disimulando elementos culturales y simbólicos difíciles de ponderar e incluso de identificar. En este artículo propongo una lectura sobre la interrupción de la reforma policial uruguaya (2010-2020) que visibiliza dichos elementos y procura brindar pistas para comprender el fracaso de reformas policiales en Latinoamérica. Los datos en los que me apoyo fueron construidos en el marco de una investigación etnográfica sobre la Policía Nacional de Uruguay, y los interpreto apelando a soportes teóricos de la antropología clásica, como las nociones de holismo, persona e individuo. Concluyo que la reforma policial uruguaya no logró interpretar cabalmente elementos simbólicos y culturales propios de la Policía (como la cosmología policial, los modos de relacionamiento social entre sus miembros y el valor simbólico asignado a la muerte), y que en esa incapacidad radican algunas claves para comprender su interrupción.
Abstract
Why do police reforms fail? The literature on public policies proposes rationalist and scientific approaches to questions of this kind, frequently disguising cultural and symbolic elements hard to ponder, and even difficult to identify. In this article, I propose a look at the interruption of the Uruguayan police reform (2010-2020) highlighting these elements while seeking to provide clues for understanding the failure of police reforms in Latin America. Data for the study was gathered within an ethnographic investigation about the National Police of Uruguay, and I analyze them through theoretical notions from classic anthropology, such as the notions of holism, person and individual. I conclude that the Uruguayan police reform failed to adequately interpret symbolic and cultural elements of the Police (such as police cosmology, the modes of social relationships between its members and the symbolic value assigned to death), and that is in this inability where we can find some keys to understand its interruption.

Published: April 2023

The city’s strategy should take into account not only the priorities of increasing investment competitiveness and the improvement of citizens’ well-being, but also the issues of sustainable development. Sustainable development of cities has been the subject of active discussion in recent years. This article proposes four modernized directions for sustainable urban development, which correspond not only to the UN Sustainable Development Goals (SDGs) (particularly SDG 11), but also to the original directives of local authorities. These directions include affordable housing, accessible and sustainable transportation systems, sustainable urbanization, and the environmental impact of cities. We developed a methodology for estimating synergies and trade-offs between and within these directions using correlation network analysis with the causality of the indicators and the lags of years. We tested this methodology by estimating the synergies and trade-offs in the sustainable development of the thirteen largest cities between 2015 and 2019. The results of the correlation network analysis are offered as a weighted directed network correlation graph. Our findings could be implemented by local authorities in the form of a Gantt chart for the optimal order of sustainable urban developmentthat could be based on the network correlation graph.
RE-IMAGINING THE ROLE OF GOVERNMENT (STATE)
Authors:   University of South Africa, Adebayo Adeyemi
Published: April 2023

This paper responds to calls for more research into public entrepreneurship, for delivering public value as opposed to the narrower view of public goods, and for re-organising states for alternative post-capitalist governance by revisiting a long-term but unresolved academic debate: the role of the state (government). It presents conceptually relevant arguments from seminal and contemporary academic debates on the role of the state and state establishments. It demonstrates that an understanding of the role of the state is a starting point in the reorganisation of states and proposes a novel additional role that most states have not yet considered, as well as identifying the state establishments that are available to assist states in fulfilling the extended role. Propositions were developed to sustain the extended role and to indicate that the approach to re-imagining the role of the state adds value for academic, practice, and policymaker observers. The report concludes by providing avenues for further research opportunities.

Published: April 2023

Aim: The Zygomatic complex [ZMC], being one of the most commonly fractured bones in the facial skeleton, is largely underreported in the literature. This study was designed to evaluate the pattern of fractures, symptomatology, and treatment modalities at our institution. Materials and methods: Information on patients’ sociodemographics, the pattern of fractures, symptomatology, radiologic diagnosis, and treatment modalities were accessed from patients’ records on our trauma register. Data collected was analyzed with SPSS 20 and the level of significance was set at p < 0.05. Results: A total of 105 patients aged 19-66 years had ZMC fractures during the study period. A male preponderance was observed [M: F = 3.8:1] and road traffic crashes [RTC] accounted for the majority of fractures [79.0%]. There was a statistically significant relationship between RTC and fractures among the age groups [X2 = 33.61, df = 5, p = 0.001]. Fractures at the zygomatico-frontal [ZF] and in combination with zygomaticomaxillary [ZM] sutures were the commonest finding on imaging [39.1% % 28.6% respectively]. Subconjunctival and circumorbital ecchymosis [92.4% and 91.4% respectively] were the commonest symptomatology. Eighty four patients (80 %) were managed via surgical intervention and the most commonly employed surgical modality was mini plates [1.0mm] fixation across either ZF [n = 33, 39.3%] or ZM [n = 21, 25.0%] suture lines. Conclusion: This study revealed that RTC remains a major aetiology of ZMC fractures and mini plate ostheosynthesis was the mainstay of surgical management. Enforcement of road safety regulations on speed and the use of protective measures by road users is imperative.

Genetic engineering field has become an imperative approach for enhancement of various bioproducts yield and productivity; and found extended applications in gene therapy, nanotechnology, as well as industrial microbiology. Modern genetic engineering tool CRISPR/Cas system, specifically the Type II system from Streptococcus pyogenes, is gaining traction in recent years and being utilized to engineer novel strains to overproduce primary fermentation product of interest. Employing this technology for non-model microorganism such as Clostridium spp is still restricted due to several limitations such as inadequate genome information, resistance against transformation, low plasmid replication, and the ability for gene expression. The prediction of CRISPR/Cas systems in microbial genomes is fundamentally the initial step towards exploitation of this technology to engineer Clostridium spp. In this study, we demonstrate a simple yet effective method to predict component of endogenous CRISPR/Cas systems, using Clostridium spp genomes as a proof-of-concept. We identified the “real” CRISPR array together with the cas gene operon consist of Type I B signature proteins in Clostridium pasteurianum which is in agreement with the previous report, implying that this strategy generates reliable CRISPR/Cas systems prediction. Thus, this provides a glimpse on how bioinformatics and biocomputational tools can be utilized to overcome barriers in genetic engineering.
Naval Policy of 1917–1920 in the Scientific Works of Lieutenant SvIatoslav Shramchenko
Authors:   Taras Shevchenko national University of Kyiv, Sydorenko Andriy
Published: April 2023

The article comprehensively analyzes the scientific output of the scientist, fleet lieutenant Sviatoslav Shramchenko, which is dedicated to the naval policy of the era of the National Liberation War of 1917–1921. On the basis of official orders, state documents, and his own memories, the author described the peculiarities of the formation of the structure of the Maritime Ministry, the development of the Black Sea Fleet, identified external and internal political factors that both contributed to and hindered these processes, characterized the general aspects of the concept of naval policy. Examining the era of the Central Council, the author noted that in 1917, the Black Sea Fleet underwent processes of Ukrainization, national and state self-awareness of sailors and officers (captains). However, the leadership of the Central Council and the General Secretariat approached the principles of the formation of the Armed Forces in general and the navy in particular from socialist positions, filled the management staff of naval departments basing on the principle of party affiliation rather than expertise, actually ignored the issue of the Crimea and, thus, did not use the potential of Ukrainianized sailors. Analyzing naval policy during the days of the Ukrainian State, Sviatoslav Shramchenko proved that its leadership attached great importance to the construction of an effective Black Sea fleet. At the state level, negotiations were held on the return of warships actually occupied by German troops, work was underway on the legal registration and staffing of ships of the fleet. The author claimed that these reforms were interrupted by the change in the geopolitical situation in November 1918 and the anti-Hetman coup of the Directory. Determining the basic aspects of the naval policy of the Directory era, Sviatoslav Shramchenko emphasized that at the first stage it followed mistakes identical to those of the Central Council era. Stabilization of the policy took place during the time of the Minister of the Navy Mykhailo Bilinskyi, but the capture of the Black Sea Fleet by the Entente and the occupation of the south of Ukraine by the Volunteer Army of Lieutenant General Anton Denikin did not allow the ideas of the naval sphere to be implemented.

Published: April 2023

In this article authors Katy Swalwell, Noreen Naseem Rodríguez, Amy Updegraff, and Leslie Ann Winters share findings from their critical content analysis of the free preK–5 resources for antiracist, social justice teaching in the Teachers Pay Teachers’ Teach for Justice collection. Using Picower’s (2012) six elements of social justice curriculum design, as well as guidelines and suggestions offered to content creators in this online curriculum market place, the authors found that the materials in the sample lacked accuracy, avoided clarity, and promoted thin conceptions of social justice and antiracism. They claim that, in general, the collection subverts traditions of social justice and antiracist education by erasing power dynamics, distracting students’ attention away from oppression, and othering BIPOC students. They conclude with a call for educators to avoid the collection and to instead invest in high-quality vetted resources as well as professional development that helps them sharpen their critical capacities around curricular resources.
Clinical laboratory diagnostics of antibodies to SARS-CoV-2: from a QR code to the reality

Published: April 2023

Background: The immune response to SARS-CoV-2 includes the production of specific immunoglobulins to protein antigens of SARS-CoV-2. Depending on the type and level of immunoglobulins, it is possible to assess the stage of the disease and evaluate the effectiveness of vaccination. The main approach to the determination of immunoglobulins to SARS-CoV-2 in human biological fluids is enzyme-linked sorbent immunoassay. Its data, in particular, are used to issue an electronic COVID-19 certificate with a QR code. However, the qualitative and quantitative composition of immunoglobulins for a QR code is not officially regulated.
Aim: measuring the immunoglobulins level in the human blood serum with different types of immunity to the new coronavirus infection (COVID-19) to select the most informative indicators of protective immunity.
Methods: The study included 76 blood serum samples from male and female volunteers (age, 18 to 50 y.o.) in compliance with the ethical standards. The detection of IgA, IgM, IgG (total to different regions of SARS-CoV-2, S-protein IgG and RBD-fragment IgG), IgG avidity, and the level of the SARS-CoV-2 N-antigen was performed by enzyme-linked immunosorbent assay (ELISA) using commercially available reagent kits.
Results: The indicators of the level of antibodies (both "protective" IgG and IgA of the initial phase of infection) are most pronounced in persons who have been vaccinated and have had COVID-19, and least pronounced in unvaccinated people. For recovered unvaccinated individuals, the level of total protective antibodies and IgG to the S-protein, including the RBD fragment, is the lowest; the avidity of IgG is lower than that in the other groups, too. The IgG avidity in vaccinated patients is higher than that in recovered ones. It should be noted that there were no differences in the level of both total IgG to SARS-CoV-2, to the S-protein and to the RBD-fragment of the S-protein for recovered and vaccinated individuals.
Conclusion: The analysis of COVID-19 immunoglobulins indicates a different profile of the humoral immune response following vaccination and previous infection with COVID-19. To quickly assess the immune response to previous and current COVID-19 infection, as well as to detect the post-vaccination immunity, it is advisable to use the total level of IgG to SARS-CoV-2. For deeper assessment of protective immunity and production of protective antibodies, it is better to evaluate the quantitative content of IgG to the S protein and its RBD fragment. The equal level of IgA in the experimental groups indicates an ongoing interaction with SARS CoV-2 in the population. Thus, the electronic COVID-19 certificate is of little use when it is formed by only one of the indicators without taking into account the rest.
Morphological features of brain damage in severe COVID-19
Authors: Kanibolotskiy Aleksander A. , Zayratyants Oleg V.
Published: April 2023

Background: The damage to the nervous system in COVID-19 reflects the systemic nature of the infection. The question of the neuroinvasive potential of SARS-CoV-2 remains open, the role of "pseudovirions" in the development of the endothelial dysfunction, as well as of the S1 subunit in the TLR activation, and the importance of the blood-brain barrier are discussed. The immunological, non-immunological, and cytopathic mechanisms of the virus's action are described; there is no clear understanding of the genesis of neuropathological changes caused by SARS-CoV-2. In this tragic pandemic, the lessons of the dead should help save lives and health. Aim: to study and explain the features of brain damage in COVID-19. Methods: Brain fragments from 20 patients who died due to severe COVID-19 were studied, the sections were stained with hematoxylin and eosin, according to van Gieson and Nissl, IHC reactions were performed with antibodies to the S-protein, CD68 and CD8, the changes were compared with those related to the lethal outcomes of pancreatic necrosis and ruptured aortic aneurysm. Results: The following changes in the olfactory analyzer were revealed: sharp edema, dystrophic changes in neurons, gliosis, accumulations of starchy bodies, which explains the neuronal pathway of SARS-CoV-2 invasion; vascular plethora, erythrostasis and thrombosis, perivenular hemorrhages, diffuse edema, macroglia proliferation, perivascular astrocytosis and satellite. A positive reaction with the antibodies to the S1 and S2 subunits of the spike protein was detected, while the result of the reaction with antibodies to the N-protein of the virus, confirming the active replication of the virus, was doubtful. The S-protein expression in individual endotheliocytes makes the transendothelial route of the virus entry unlikely, in contrast to the hematogenous and neuronal pathways. The viral DNA was not detected by PCR. A weak inflammatory reaction was revealed in the form of perivascular accumulations of lymphocytes, scattered T-lymphocytes. Conclusions: 2 groups of changes were identified, the first group included circulatory disorders with a tendency to thrombosis, edema, dystrophic-necrotic changes in neurons, glial proliferation, the second group included inflammatory-degenerative changes, a weak inflammatory reaction and amyloid-like bodies. Further morphometric and statistical studies are needed to obtain the reliable conclusions.

Published: April 2023

Background: Secondary immunodeficiency in recipients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the pediatric practice is often accompanied by bacterial and viral infections of the gastrointestinal tract (GIT), resistant to conventional therapy. Fecal microbiota transplantation (FMT) promotes intestinal recolonization and eradication of gastrointestinal symptoms.
Clinical case description: A 2.5-year-old patient underwent allo-HSCT from a haploidentical related donor (father) as a part of the treatment of acute myeloid leukemia. A month after the last procedure, diarrhea (up to 10 times a day) and abdominal pain appeared. The astrovirus RNA and Clostridium difficile toxin A were detected in the feces. The FMT was prescribed. After two FMT procedures, the intestinal syndrome leveled out, and the tests for the astrovirus RNA and clostridial toxins were negative. The content of cholic and, in particular, deoxycholic acids, as well as their conjugates with glycine and taurine, in the feces increased; the acetic acid content increased with a simultaneous decrease in the level of propionic acid, which indicates the restoration of the intestinal microbiota’s functional potential.
Conclusion: FMT contributes to the restoration of the normal intestinal microflora, the elimination of clostridial toxins, enteroinvasive E. coli and astrovirus infection in allo-HSCT recipients, as evidenced by the indicators of the intestinal microbiota activity, and can be used in allo-HSCT recipients with infections refractory to conventional therapy.
The Difficulties of Applying Management Systems Based on High-Powered Incentives in State Corporations
Authors: Agamirova Maria E.
Published: April 2023

The article discusses the possible negative effects of the implementation of the market motivation methods in the public sector and management systems of state corporations. In particular, we focus on the introduction of performance assessments of civil servants which are based on a number of quantitative indicators. There is a belief that high-powered incentives can make this relationship closer. However, such incentives can lead to the negative contract externalities which had been analyzed for the past few decades in the framework of the contract theory. Applying such motivation practices is not always successful even in the business environment; we assume that such practices are not suitable for the public sector. It is also worth mentioning that the performance indicators, the choice of which is left to officials, have only one positive feature - observability, and thus have a weak connection with the final result of the evaluated process.
GEOLOGICAL FIELD GUIDE TO THE EARLY CRETACEOUS INHANDUÍ HOTSPRINGS AND THEIR HOST BOTUCATU PALEODUNES

Published: April 2023

Structures formed by geological processes that occurred during the Early Cretaceous are preserved in large areas of the Fronteira Oeste Rift in Rio Grande do Sul, Brazil. Among these areas, the Inhanduí Paleodune Field (IPDF), located in northeastern Alegrete, is part of the Botucatu paleoerg, the largest paleodune field in Supercontinent Gondwana. This area shows hundreds of circular and curvilinear dunes of silicified sandstone of variable sizes, which were covered by intraplate Paraná volcanic rocks. This field guide provides the information for a field trip from Porto Alegre, Brazil to two hills (Cerros) in the IPDF, Cerro Farrapo and Cerro Figueirinha. Important features formed by hot water, volcanic rock and sediment interaction are preserved in large outcrops in these hills, including extensive silicification and deformation of the buried dunes, injection of fluidized sand and explosive hydrothermal activity. Hydrothermal structures include preservation of subterranean conduits that emerged at the Earth’s surface to form surging hot pools, geysers and spouts. These features are preserved as bowls, rounded to polygonal cavities and prismatic and lozenge-shaped clasts and blocks. Access to the outcrops is mostly via paved roads, with 40 km in unpaved roads.

Published: April 2023

Mato Grosso do Sul has a significant area with Devonian outcrops containing fossils mainly of marine invertebrates, plants and, more rarely, fish fragments of the climax and impoverished Malvinoxhosan (= Malvinokaffric) fauna. Despite this, for a long time the state had a lack in studies related to the Devonian paleontology of the Paraná Basin, only gaining prominence from the 2010s onwards. Therefore, the objective of this work is to present a guide of the fossiliferous Devonian outcrops recognized so far in the state, which are located in the municipalities of Rio Negro, Rio Verde de Mato Grosso, Coxim and Pedro Gomes. The outcrops presented here represent a true geopaleontological heritage in situ. Divulge them is vital not only for their preservation, but also for the dissemination and appreciation of paleontological science among society in general.

Management of Environmental and Social Risks Within Sustainable Project Finance: Solving Tensions to Enable Sustainable Development
Authors: Mertens Daniel , Klingenberger Lars , Frère Eric , Harder Daniel , Zureck Alexander
Published: April 2023

This paper examines the management of environmental and social (E&S) risks within sustainable project finance. To approach this matter scientifically, a qualitative interview approach has been conducted predominantly with experts from the engaged parties of banks and project companies as part of this research. The corresponding analysis reveals that both parties use the standards for sustainability reasons and as a tool for their risk management. Moreover, growing political pressure justifies an accelerated standards application. In line with the literature, it can be confirmed that E&S standards are also introduced for reputational reasons. However, in contrast to previous findings, the relationship is perceived by the respective parties as a trusting partnership. In addition to current knowledge, there is slight disagreement over the social requirements of banks, challenging its practicability.

Germ and seed morphometric parameters of seeds of vegetable plants of the Umbelliferae family as a breeding subject
Authors: Bukharov A. F.
Published: April 2023

The work is devoted to the study of statistical parameters of the linear dimensions of the seed, endosperm and embryo, variability, correlations, and the manifestation of these traits in hybrid combinations. Morphometric parameters largely determine the quality of seeds. The presence of an underdeveloped embryo determines the duration of the period of heterotrophic development of the seedling, affects germination, energy, longevity, seed response to changes in germination conditions, and, ultimately, increases the interphase period from sowing to germination. The article shows the high variability of these parameters in numerous representatives of vegetable crops - representatives of the Umbelliferae (Apiaceae) family, analyzes the causes that cause them, and predicts the potential use of this variability in breeding programs. The object of research was the seeds of various varieties of carrots, parsley, parsnips, celery, dill. Measurement of the length of the seed and endosperm was carried out using a caliper. The length of the embryo was determined using a microscope and a video eyepiece at ×40 magnification using the Scope Photo program. The experiment was repeated four times, in each repetition at least 20 seeds. The values of the coefficient of variation in the length of the endosperm and seed varied from 9 to 19%, depending on the species and cultivar characteristics. The variability of the embryo reached 18-28%. between the size of the embryo on the one hand and the length of the endosperm (0.208-0.369) and seed (0.213-0.376) on the other, weak correlations were noted, indicating the independent inheritance of these parameters. The hereditary conditionality of the variability of the embryo, endosperm and seed of carrots (50.8-86.5%) and parsnips (49.6-58.9%) is shown, which characterizes the real possibility of their breeding improvement. In the process of studying distant hybrids of carrots (the parental forms of which differed sharply in morphometric parameters of seeds), it was found that F1 hybrids for these traits predominantly showed positive overdominance (38.1%) and dominance (16.7%). According to the complex of relative parameters (indices), negative overdominance (23.8%) and dominance (4.8%) were more often noted. The results of many years of research indicate that the morphometric parameters (length of the seed, endosperm, embryo) and their ratios (indices) of seeds, like any other biological traits, are genetically determined and depend on species and cultivar characteristics. A comparison of wild-growing and varietal samples of carrots indicates that in the process of cultivation, the size of the embryo underwent significant upward changes, even in the absence of targeted selection. Therefore, when applying artificial selection in this direction, one can expect more significant results.

The article presents the results of the selection work of the laboratory of breeding and seed production of table root crops of the Federal Scientific Vegetable Center for the culture of Chinese radish (loba). From the collection material (a total of 23 samples were studied), a promising material was selected under the number No. 600 for a complex of economically valuable features. The purpose of the research is to create a variety of Chinese radish – loba for open and protected ground. Based on this goal, the objectives of the research included: to evaluate a promising variety of loba in a nursery of competitive variety testing in open and protected ground conditions, to assess alignment according to the main morphobiological parameters, as well as to assess the safety and resistance to diseases during storage.

Results. As a result of repeated individual and family selection in the direction of productivity, resistance to premature stem formation and diseases of vegetation and storage, as well as improvement of taste qualities, a new variety of Chinese radish Serdtse Podmoskovya was bred. The new variety belongs to the pink-red rounded varietal type. The root crop is flat-rounded, large in size. The flesh is white, juicy, with a slightly spicy taste. The variety is medium-ripened, the growing season is 65-75 days, suitable for use in early summer, autumn and winter, resistant to longterm storage (95-96% preservation) and low light. The yield of the variety in protected ground is 2.7 kg/m2, marketability – 88.7%, root crop weight – 533 g; dry matter content – 6.26%, sugars – 2.56%, ascorbic acid – 19.36 mg%. The variety on this background was distinguished by the absence of flowering and diseased plants. The yield in the open ground was 31.2 t/ha (3.12 kg/m2), marketability – 81.2%, root crop weight – 281 g. The variety under these conditions was characterized by a higher content of dry matter –11.0%, sugars – 3.2% and ascorbic acid – 20.13 mg%; a small percentage of flowering (9.4%) and affected plants (6.3%) was noted. For this variety, a technology has been developed for obtaining original and elite seeds according to a one-year development cycle in the conditions of the Central region ща Russia.

Relevance. From an agrotechnical point of view, beans are a valuable crop capable of greening agriculture. Legumes have the ability to enter into symbiotic relationships with nodule nitrogen-fixing bacteria and assimilate atmospheric nitrogen. The creation of highly efficient plant-microbial systems in agrocenoses by breeding new varieties of legumes with a high symbiotic potential is a promising direction that makes it possible to control the efficiency of plant biomass accumulation and the quality of agricultural products. There is a need to evaluate varieties for adaptability and nodule-forming ability to implement breeding programs to create highly productive and high-quality varieties that can realize the genetic potential of productivity in the sharply continental climate.

Materials and methods. On the basis of the Federal State Budgetary Educational Institution of Higher Education Novosibirsk State Agrarian University in 2018-2020, an assessment was made of green bean varieties of different ecological and geographical origin with a bush type of growth. Experimental fields are located in the village of Michurinsky (left bank of Novosibirsk) and the educational and production farm "Garden of Michurintsev" (right bank of Novosibirsk). The study of samples in terms of adaptability parameters, as well as the ability to form nodules, was performed in accordance with generally accepted methods. We took into account the characteristics that affect the productivity of the crop - the number and weight of beans per plant, the weight of one bean, and the yield. The aim of the work is to evaluate the varieties of vegetable beans for adaptability and nodule-forming ability in the conditions of the forest-steppe of the Siberian region.

Results. When forming the symbiotic apparatus, the growth conditions were taken into account. It has been established that high rates of biomass are observed on the territory of the village of Michurinsky. Varieties Morena and Maguyra are characterized by intensive growth in the experimental field of the village of Michurinsky, varieties Zoluyshka and Solnyshko – the educational and production farm "Garden of Michurintsev". The total number of nodules per plant varied from 29 (Kormilitsa) to 66. (Zoluyshka), active nodules – from 9 (Kormilitsa) to 49 (Zoluyshka). It is noted that the varieties Solnyshko and Zoluyshka have high rates of general adaptive ability and breeding value of the genotype. A strong relationship has been established between the characteristics of leaf mass and the number of active nodules, the number of active nodules and the leaf surface area; average - between the number of active nodules and plant biomass.
