Authors: Kryvda Maryna , Rybachuk Zhanna
Published: January 2022

Escherichia coli is the normal microbe of the intestinal microflora but can cause different illnesses exception the intestinal tract. And the most problem of the illness with E. coli etiology is the rapid antibiotic resistance forming of the current pathogen. We had the aim to detect the antibiotic susceptibility of E. coli strains separated from the samples of the ill cattle in endometritis and mastitis. 12 types of antimicrobial preparations were tested. We have founded, wild E. coli strains were totally resistant to vancomycin, streptomycin, tetracycline, doxycycline, kanamycin, amoxicillin, and tylosin. Drugs of the cephalosporine range also were un-efficient. And just furazolidone, enrofloxacin, and gentamycin have shown the effective action to tested samples of E. coli. So, the testing of antibiotic susceptibility is the obligatory action in therapy-list formation. Just this action can demonstrate the efficient antimicrobial drugs that can provide the recovery of the illness animals.

ESTIMATION OF RESISTANCE OF INTRODUCED VARIETIES OF TULIPS (TULIPA L.) TO DAMAGE BY BOTRYTIS CINEREA PERS TULIPAE GRAY ROT IN THE CONDITIONS OF THE RIGHT BANK FOREST STEPPE OF UKRAINE
Authors: Polishchuk V. , Mykolayko V. , Polishchuk T. , Kalyuzhna L.
Published: January 2022

Fifty introduced tulip varieties (TULIPA L.) were evaluated in the conditions of the Right-Bank Forest-Steppe of Ukraine, represented by different genotypes, mainly foreign selection, for resistance to gray rot Botrytis CinereaPersTulipae.However, as with most flowering plants, tulips are damaged by pests and diseases. It is known that the main source of infection is the soil, especially when growing tulips in monoculture. From the soil, fungal spores penetrate into the roots of the plant and spread through the leading vessels into the stem. The accumulation of mycelium of the fungus in the vessels prevents the transfer of nutrients and moisture. This disease is so dangerous that today, there are almost no varieties of tulips that would be absolutely stable to this disease. However, there are advantages, namely - if the tulip variety is early ripening and it has already completed the flowering phase before the disease, then such plants are resistant and adapted to gray rot. A brief agrobiological and decorative characteristic of collection varieties in the conditions of the Right-Bank Forest-Steppe of Ukraine is given. The resistance of plants to damage to gray rot was carried out in accordance with the current methods, that is, on 25 plants of the 50 studied introduced tulip varieties, damage to vegetative and generative organs was visually determined after planting in the soil in spring.Atypical plants or those damaged by the disease were marked with special ribbons, and then culling was carried out and the percentage of affected plants was calculated. After the complete ontogeny of tulip plant varieties, the bulbs were dug out and carefully checked for disease infection before storage. Field observations regarding the resistance of various tulip cultivars to gray rot in the Forest-Steppe conditions of Ukraine investigated that the incidence of genotypes was at a low and very low level, despite the contrasting weather conditions of different years of research.

Published: January 2022

The article presents the results of studying symbiotic systems in agrocenoses of sowing peas, depending on the influence of technology elements. The studies were carried out using biological preparations and plant growth stimulants during 2018-2019. On gray forest medium loamy soils. It is noted that the use of seed inoculation with strains of nodule bacteria in the latest technologies for growing leguminous crops provides the formation of an active legume-rhizobial symbiosis, an increase in the rate of assimilation of nitrogen from the air and an increase in plant productivity.
It was found that the formation of the largest tuber biomass in the Metsenat variety 2.36 g/plant was noted at the stage of growth and development of BBCH 61-65 in the variant of the experiment, where pre-sowing treatment of seeds with a complex of bacterial preparations Biokompleks + Mikofrend and foliar feeding with a plant growth stimulator Regoplant in the phase budding against the background of mineral fertilizer N30P60K60. The same elements of technology ensured the formation of the maximum indicators of the active symbiotic potential and the amount of biologically fixed nitrogen, respectively, 13.6 kg • days/ha and 110.6kg/ha. Bacterization of seeds with microbial preparations contributes to the introduction of beneficial microorganisms into agrophytocenoses and is an element of organic farming based on the methodology of environmentally friendly technologies, restoration of natural resources and their energy conservation. As a result of the research carried out, the treatment of pea seeds with a sowing complex Biokompleks (2 l/ha) + Mikofrend (1 l/ha) against the background of mineral fertilizers (N30P60K60) and foliar feeding with a growth stimulator Regoplant (50 ml/ha) contributes to a significant increase in the amount and biomass bubbles. A positive nitrogen balance was noted in all variants of the field experiment, and its greatest amount remained not in the variants with high fixation of atmospheric nitrogen. The use of mineral fertilizer N30P60K60 and pre-sowing seed treatment with the Biokompleks + Mikofrend complex provided the largest amount of biologically fixed nitrogen, remained in the soil at a level of 66.4 kg/ha.

Published: January 2022

Annotation
Purpose. Analyze current trends in the market of vegetable crops and identify factors that shape the situation in the vegetable market.
Methods. In the course of the research, the methods of monographic, system analysis and synthesis were used.
Results. The current trends in the vegetable market both in the world and in Ukraine are identified: the dynamics of production, consumption and prices are traced, the directions of development of the vegetable market are determined. The vegetable market is characterized by complexity and segmentation due to the large variety of vegetables, which differ in terms and features of cultivation, location of production, methods of use and storage, and the peculiarity of the vegetable industry is that the vast majority of vegetables – 85% are produced in households. The main components of the vegetable market in Ukraine are considered, namely: demand and supply of vegetables, trends in vegetable prices, the state and problems of market infrastructure development.
Conclusions
Today, vegetable growing is one of the priority areas of agricultural production in Ukraine. The vegetable market of Ukraine is quite self-sufficient, its capacity depends on production volumes. The main producers of vegetable products are households, the share of which from the total number of its producers is over 85%. The main factors that inhibit the development of vegetable growing are: low development of logistics; the state still has a system of spontaneous sale of vegetables; small number of vegetable storages; vegetable cooperatives, etc. do not function.
Improving the efficiency of vegetable production is possible if it is provided during the production of vegetable products: the use of new resource-saving production technologies, which in turn will lead to a reduction in labor costs, reducing the cost of vegetable production; by optimizing the organization of production in the industry, namely the construction of the required number of vegetable storages, the creation of processing units in large farms, and for households to unite in appropriate vegetable cooperatives, which will rationally use all grown products and optimize sales channels.

This paper studies categories of definable subassignments with some category equivalences to semi-algebraic and constructible subsets of arc spaces of algebraic varieties. These equivalences lead to the identity of certain Grothendieck rings, which allows us to compare the motivic measure of Cluckers-Loeser with that of Denef-Loeser for certain classes of definable subassignments.

Her kültür, renk ve dilden insanı bir araya getiren internet, küresel vatandaşın ana arteri olurken etik anlamda birçok yeni sorun alanı da oluşturmuştur. Siber panoptipik ortamın yapısı, büyük verinin işlenişi ve çıkar gruplarınca kullanılması, manipülatif algoritmalar, trash-streaming post truth, deep fake yankı fanusu ve bunun gibi daha birçok yeni etik problem alanı, dijitalleşen medya ile hayatımızdaki yerini
almıştır. Dijital teknolojinin manipülasyonun önünü açan bu olumsuz özellikleri, anlık küresel etkileşimi sunan iletişimsel yapısı ile birleştiğinde; nefret söyleminin üretilmesi, meşrulaştırılması hatta olmayanı oluyor gibi göstererek önlenemez bir hızda yayılmasının önünü açmaktadır.

Facebook, Instagram, Twitter, YouTube gibi sosyal paylaşım ağları gerek Türkiye’de gerekse de dünyada her geçen gün yaygınlaşan bir kullanıma sahiptir. Bu mecraların etkisiyle habere ve bilgiye ulaşma kolaylaşmış ancak haberlerin üretilme, yayılma ve tartışılma şekli de büyük bir değişime uğramıştır. Sosyal medyanın yeni iletişim akışlarını kolaylaştırabileceğine, insanların kamusal meseleler etrafında bağlantı kurmasına ve ağ oluşturmasına imkân tanıdığını söyleyebilmek mümkündür. Basılı gazeteler, radyo ve televizyon gibi büyük ölçüde tek yönlü kitle iletişim araçlarının insan hayatına hâkim olduğu bir yüzyıldan sonra, internetin yükselişi ve özellikle ücretsiz ve kullanımı kolay etkileşimli platformların ve sosyal paylaşım ağlarının geliştirilmesi ve yaygınlaşması ister istemez sanal ortamdaki araştırmaların önemini gözler önüne sermiştir .
Evolutionary aspects of the human-oriented economy in the categorical-system methodology
Authors: Nasyrova Svetlana
Published: January 2022

The object of the research is human-oriented economy. The purpose of the study is to develop a model for the development of human-centered economy through its gradual complication. The author puts forward a hypothesis that the development of an hierarchy of objectively necessary human needs will provide a basis for identifying the structure of a new economic system with targets focused on gradual development of each economic entity and the economy as a whole. The study applies the methods of content analysis and the «Final information flow» method. The author first performs identification and cognition of qualitative characteristics of human-oriented economy based on the «Finite information flow» method using such parameters as logical level, logical limit and transformability. He then formulates the logical levels of human-centered economy development on the basis of human needs allocation, determines the presence of diverse structures within the framework of a human-centered economy, and presents human-oriented economy as a object gradually becoming more complex. The practical and theoretical findings of the study prove that the comprehension of human-centered economy through «Final information flow» method may serve as a basis for further research aimed at building a scientifically grounded theory of the phenomenon under study.
Predicting the yield spreads on the Russian debt market
Authors: Erofeeva Tatyana
Published: January 2022

The article provides an empirical study of factors which make a significant impact on the yield spread of corporate bonds on Russia’s market. Unlike most studies based only on IPO data, the current study covers primary and secondary markets data of 2010–2019. The aim of the study is to test the method allowing to build a model capable of predicting the yield spread with maximum approximation to actual value. The author develops a regression model applying a cross-validation method, a procedure for empirical assessment of the model generalizing ability. An important prerequisite is the inclusion of a limited number of regressors with high explanatory power in the model, stability over time, and explicit economic interpretation. The paper confirms the key hypothesis on high degree of issuer's rating on the yield spread which is a new step in the study of the Russian market. The findings prove that the yield spread is determined mainly by the level of risk corresponding to the degree of the issuer's reliability. The issuer's industry affiliation, the size of the company, the MSCI
stock index has also a significant impact on the spread. Among the advantages of the proposed model is its relative simplicity, explicit economic interpretation and stable response to various data which determine the practical significance of the work. The approaches to building and testing the model applied in this work can be useful in further studies aimed at developing predictive models of this class.

ENVIRONMENTAL, SOCIAL, AND GOVERNANCE (ESG) PRACTICE AND FIRM PERFORMANCE: AN INTERNATIONAL EVIDENCE
Authors: Shaikh Imlak
Published: January 2022

This article attempts to bring quantitative evidence of a firm’s sustainability reporting in terms of non-financial voluntary disclosures. The disclosures are made available through the annual report and Corporate Social Responsibility (CSR) and Global Reporting Initiatives (GRI) report. ESG score is a quantitative measure developed and disseminated by Bloomberg, covering about 120 Environmental, Social, and Governance aspects. The study’s research problem is to examine the effects of non-market transnational sustainability strategy on firm performance. The study presents an analysis of nearly 510 firm’s ESG scores across 17 countries for 2010–2018. The descriptive and inductive statistical analysis shows that ESG compliance is more pronounced in European companies. Simultaneously, Asian firms are more disciplined concerning the energy sector, and the Asiapacific counterpart is more inclined toward technology firms. The study shows that GRI and nonGRI companies differ significantly in their accounting performance (ROA and ROE) and market valuations (Tobin’s-Q). The environmental dimension appears intimidating across accounting and market-based firm performance, while the social dimension contributes adversely, and governance positively affects operational efficiency.

Published: January 2022

We have conducted mapping observations (∼2′ × 2′) of the Class I protostar L1489 IRS using the 7 m array of the Atacama Compact Array and the IRAM 30 m telescope in C18O 2–1 emission to investigate the gas kinematics on 1000–10,000 au scales. The C18O emission shows a velocity gradient across the protostar in a direction almost perpendicular to the outflow. The radial profile of the peak velocity was measured from a C18O position–velocity diagram cut along the disk major axis. The measured peak velocity decreases with radius at radii of ∼1400–2900 au, but increases slightly or is almost constant at radii of r ≳ 2900 au. Disk-and-envelope models were compared with the observations to understand the nature of the radial profile of the peak velocity. The measured peak velocities are best explained by a model where the specific angular momentum is constant within a radius of 2900 au but increases with radius outside 2900 au. We calculated the radial profile of the specific angular momentum from the measured peak velocities and compared it to analytic models of core collapse. The analytic models reproduce well the observed radial profile of the specific angular momentum and suggest that material within a radius of ∼4000–6000 au in the initial dense core has accreted to the central protostar. Because dense cores are typically ∼10,000–20,000 au in radius, and as L1489 IRS is close to the end of its mass accretion phase, our result suggests that only a fraction of a dense core eventually forms a star.

Background: Interleukin-1 receptor antagonist (IL-1Ra) also known as Anakinra is a receptor antagonist of IL-1 especially IL-1β. IL-1β increased in infected COVID-19 patient groups. This study aimed that the IL-1Ra contained in Conditioned Medium Wharton’s Jelly Mesenchymal Stem Cells (CM-WJMSCs) has the potential to inhibit IL-1β which is one of the cytokine storms that occur in COVID patients through an in-silico approach. Objective: This study aims to determine the effect of in silico approach pro-inflammatory protein interleukin 1β (IL-1 β) and interleukin-1 receptor antagonist protein as  cytokine WJ-MSCs for potential treatment of COVID-19 disease. Methods: 3D structure using the homology modeling method on Swiss Model web-server.  Molecular docking was performed to analyze the binding mode of the IL-1β related to COVID-19 with IL-1Ra and the docking results were fixed using FireDock web-server. Results: These results of the docking of proteins between IL-1β and the CM-WJMSCs component, namely IL-1Ra showed that IL-1Ra has criteria for docking on IL-1β such as the good score for QMEAN, good CscoreLB, and BS-score results, and the lowest energy obtained was -585.1 KJ/mol. It can be predicted that IL-1Ra can inhibit IL-1β which causes cytokine storms in COVID-19 patients.  Conclusion: So that there is a potential treatment of CM-WJMSCs on the severity of Covid-19 infection.
A Novel Real-Time Edge-Cloud Big Data Management and Analytics Framework for Smart Cities
Authors: Cavicchioli Roberto , Martoglia Riccardo , Verucchi Micaela
Published: January 2022

Exposing city information to dynamic, distributed, powerful, scalable, and user-friendly big data systems is expected to enable the implementation of a wide range of new opportunities; however, the size, heterogeneity and geographical dispersion of data often makes it difficult to combine, analyze and consume them in a single system. In the context of the H2020 CLASS project, we describe an innovative framework aiming to facilitate the design of advanced big-data analytics workflows. The proposal covers the whole compute continuum, from edge to cloud, and relies on a well-organized distributed infrastructure exploiting: a) edge solutions with advanced computer vision technologies enabling the real-time generation of “rich” data from a vast array of sensor types; b) cloud data management techniques offering efficient storage, real-time querying and updating of the high-frequency incoming data at different granularity levels. We specifically focus on obstacle detection and tracking for edge processing, and consider a traffic density monitoring application, with hierarchical data aggregation features for cloud processing; the discussed techniques will constitute the groundwork enabling many further services. The tests are performed on the real use-case of the Modena Automotive Smart Area (MASA).
