Purpose. To generalize and analyze the data provided by state phytosanitary inspections of the Department of Phytosanitary Safety of the State Veterinary Service of Ukraine on the dynamics of development of the main pests in sugar beet stands in Ukraine in 2019 and to forecast their appearance and possible damage in the current year. Methods. Field, accounting, analytical. Results. In 2020, sugar beet crops may be damaged by beetroot weevil, grey beetroot weevil, beet stalk borer, beet flea, beet leaf miner, beetroot aphids and other pests. According to the results of autumn field monitoring, 57% of beet areas was colonized by beetroot beetle with an average number per 1 m2 of 0.5–1.0 (beetles, pupae) with the maximum number of 2–9 in Volyn, Kyiv, Poltava, Cherkasy, Chernihiv, Zhytomyr, Sumy regions. During the autumn excavations, the beetles in the population were 75%, pupae 20% and larvae 5%. In respect to grey beetroot weevil, it made the greatest damage to sugar beet crops in Kyiv, Poltava, Kharkiv, Sumy, Volyn, Kirovohrad, Khmelnytsk, and other regions, where it colonized 24–100% of stands with an average number of 0.1–0.6 with a maximum of 0.6–1.0. It damaged, on average, 2–6% of stands with the maximum of 7–12%. Autumn monitoring of the pest found a significant number of the pest in all beetroot regions with an average number of 0.5–0.7 with the maximum of 1.0–4.0. In addition, autumn monitoring revealed a significant number of beet stalk borer (average 0.1–0.7, maximum 0.7–1.0 specimens) in farms of Poltava and Cherkasy regions. Beet tortoise beetles were detected on 10–100% of the monitored area with an average number of 0.1–0.4, which is lower than in long-term observations. In the majority of areas, goosefoot tortoise beetles dominated (33–100%). On average, the ratio was 54% of goosefoot and 46% of beet root tortoise beetles. The wintering stock of beet beetle was slightly lower than in the last year and amounted to an average of 14–54, with the maximum in Vinnytsia, Rivne, Khmelnytskyi regions (76–100). Autumn inspections of host plants (red bilberry, snowball tree, jasmine) revealed 12–36, maximum 150 wintering eggs of leaf aphids per 1 meter of a branch. The wintering stock of beet leaf miner was 0.8–1.8, somewhere 2.9 (in Ternopil, Vinnytsia Khmelnytsk regions), which is at the level of the last year’s numbers. Conclusions. The wintering stock of harmful sugar beet insects exceeds the generally accepted economic thresholds for harmfulness. The timely prognosis of the development and reproduction of sugar beet pests and the application of a complex of organizational, economic, biological and chemical measures to control their numbers will create conditions for the preservation of root harvest, improving root quality and reduce unreasonable pollution of the environment with chemicals.

Researches, which have lasted for two years, were carried out on long-term trial field at Rimski Sancevi, Novi Sad, Serbia. In this trial, the eight fertilization variants of N, P2O5 and K2O increased amounts were studied. Sugar beet root and tops yields were determined, as well as the elements of technological sugar beet root quality. Based on these results, percentage of sugar utilization and refined sugar yield was defined. In the spring, before applying of N fertilizer, amount of nitrate nitrogen in the soil and its influence on yield and quality was determined. The highest root yield in 2002 was produced at the variant N100 P150 K150, and in 2003 at the variant N150 P150 K150. However, in both years, referring to the variant N100 P100 K100, the differences were not statistically significant. Increasing of nitrogen amounts had negative effects on refined sugar yield. Amounts of NO3-N in the soil in spring, before sugar beet sowing, in 2002 had significant influence on root yield and refined sugar yield. In the year 2003, which was highly dry, high correlation ratio were gained between amounts of NO3-N in the soil and root quality parameters, but it wasn't significant between nitrogen amounts and root and refined sugar yield.

Величина неучтенных потерь сахара в России составляет 0,06–0,14 млн т в год, что обусловливает необходимость внедрения мероприятий по их снижению. В статье представлены результаты исследований по снижению микробиологической обсемененности диффузионного сока, очищенного сока II сатурации и сиропа, выведенного на длительное хранение. Рассмотрены причины, обусловливающие обсемененность корнеплодов сахарной свеклы патогенными микроорганизмами. Приведена методика постановки лабораторных исследований. Установлено, что на стадии обработки экстрагента применение сернистого ангидрида позволяет снизить обсемененность диффузионного сока МАФАнМ и плесневыми грибами на 41,75 и 40,26% соответственно. На стадии обработки фильтрованного сока II сатурации применение сернистого ангидрида снижает обсемененность сока МАФАнМ на 76,67% и практически полностью обеспечивает угнетение плесневых грибов. На стадии обработки сиропа применение сернистого ангидрида позволяет снизить обсемененность сиропа после длительного хранения МАФАнМ и плесневыми грибами на 68,97 и 58,33% соответственно, тогда как применение бисульфита натрия – только на 31,03 и 33,33% соответственно. На основании результатов исследований сделан обоснованный вывод, что обработка полупродуктов свеклосахарного производства сульфитсодержащими реагентами, а именно сернистым ангидридом, является эффективным технологическим приемом для обеспечения снижения неучтенных потерь сахарозы, возникающих в результате жизнедеятельности микроорганизмов. The value of unaccounted sugar losses in Russia is 0,06–0,14 million tons per year, which makes it necessary to implement measures to reduce them. The article presents the results of studies to reduce the microbiological contamination of diffusion juice, purified juice of the and syrup removed for long-term storage. The reasons for the contamination of sugar beet root crops with pathogenic microorganisms are considered. The method of setting up laboratory tests is given. It was found that at the stage of processing the extractant, the use of sulfurous anhydride reduces the contamination of the diffusion juice with MAFAnM and mold fungi by 41,75 and 40,26%, respectively. At the stage of processing filtered juice of second carbonation, the use of sulfur dioxide reduces the contamination of MAFAnM juice by 76,67% and almost completely suppresses mold fungi. At the syrup processing stage, the use of sulfurous anhydride reduces the contamination of the syrup after long-term storage by MAFAnM and mold fungi by 68,97 and 58,33%, respectively, while the use of sodium bisulfite – only by 31,03 and 33,33%, respectively. Based on the results obtained, a reasonable conclusion is made that the treatment of beet sugar production intermediates with sulfite-containing reagents, namely, sulfur anhydride, is an effective technological technique to ensure the reduction of unaccounted losses of sucrose resulting from the vital activity of microorganisms.

Energy Justice

Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.

The aim of the current research has been to determine the dependences between the design and kinematic parameters of the sugar beet roots vibra- tion digging-out technological process from soil , which provide the ir non-damage. Methods . For the aim ac- complishment, the methods of design mathematical models constructing based on the classical laws of me- chanics are applied. The solution of the obtained differential equations is accomplished with the PC involve- ment. Results . The differential equations of the sugar beet root’s motion in course of the vibration digging-out have been comprised . They allow to determine the admissible velocity of the vibration digging working part’s forward motion depending on the angular parameters of the latter. In the result of the computational simula- tion i.e., the solution of the obtained analytical dependence by PC, the graphic dependences of the admissible velocity of plowshare v ibration digging working part’s forward motion providing the extraction of the sugar beet root from soil without the breaking-off of its tail section have been determined. Conclusions . Due to the performed analytical research , it has been established that γ = 13 ... 16 ° , β = 20 ... 30 ° should be considered as the most reasonable values of γ and β angles of the vibration digging working part providing both its forward motion optimum speed and sugar beet root digging-out from the soil without damage . On the ground of the data obtained from the analytical rese arch, the new vibration digging working parts for the sugar beet roots have been designed; also the patents of Ukraine for the inventions have been obtained for them.

Introduction. There is a lack of knowledge of the pathophysiological mechanisms that form peripheral nerve disorders in mercury lesions of professional origin. The study aims to reveal the mechanisms underlying peripheral nerve damage in the long-term post-contact period of chronic mercury intoxication (CMI). Materials and methods. Fifty-one people had the diagnosis of a long-term period of CMI. The post-contact period was 8.5±2.6 years. The authors compared the results with a control group of 26 healthy men who had no contact with toxic substances. Stimulating electroneuromyography was performed. We studied the body systems that could contribute to the formation of disorders in the peripheral nerves. Changes in peripheral hemodynamics were studied using reovasography. The content of autoantibodies, neuron-specific enolase, serotonin, histamine, catecholamines (epinephrine, dopamine), metanephrine, and neurotrophin-3 was reviewed. The content of ceruloplasmin, secondary products of lipid peroxidation processes, reduced glutathione, the activity of superoxide dismutase and the content of nitric oxide levels were determined. Results. The study established pathogenetic structural links of peripheral nerve disorders. The autoimmune process's role was to increase the range of antibodies to the MAG protein and increase the level of antibodies to DNA. Violations of elastic-tonic properties of peripheral vessels could be associated with the functional state of motor axons. The increased content of neurotransmitters is related to the state of peripheral blood circulation; the most pronounced changes were on the legs, which could contribute to the occurrence and maintenance of vasoconstriction. The role of oxidative stress in the formation of demyelinating disorders in patients' peripheral nerves in the long-term period of CRI is possible. Conclusion. Neuroimmunological processes has an essential role in the development of peripheral nerve demyelination was shown, which consists in an increase in the content of antibodies to the MAG protein expressed on Schwann cells of peripheral nerves and in an increase in the level of antibodies to DNA involved in the formation of demyelinating changes when exposed to metallic mercury. The revealed pathological changes in the state of the peripheral blood circulation, characterized by a violation of the vessels' elastic-tonic properties, leading to demyelination of motor axons in patients in the long-term period of CMI. The increased content of neurotransmitters in the examined is of great importance in the state of peripheral circulation. Pronounced changes in blood circulation are established on the lower extremities, which may be associated with the predominance of α-adrenergic receptors in the arterial bed and may contribute to the occurrence and maintenance of vasoconstriction in the legs. The relationship between changes in indicators of oxidative stress, consisting of a decrease in the value of superoxide dismutase and reduced glutathione, and the formation of demyelinating disorders of peripheral nerves in patients in the long-term period of CMI has been proved.

The essence of such concepts is “financial service”, “financial ser- vices market”, and “participants of the financial services market”; determined the purpose of state regulation of the financial services market; forms of state regu- lation of the financial services market; financial services that are present in the financial services market; the structure of state regulation bodies of the financial services market in Ukraine is given; The role of state bodies in the regulation of the financial services market was studied; to characterize the regulatory le- gal regulation of the financial services market in Ukraine; the main problems of functioning of the domestic market of financial services are revealed; ways to solve existing problems. It is grounded that the state regulation of financial ser- vices markets consists in the state’s implementation of a set of measures aimed at regulating and overseeing financial services markets to protect the interests of financial services consumers and preventing crisis phenomena. It is concluded that the financial services market is an important element of the development of the economy as a whole, in particular, it concerns not only the state but also society. We must understand that when this market is settled, that is, all bodies that carry out state regulation are competent in their powers, only then will we make informed, effective decisions about the normal and effective functioning of the RFP. It is important that the data of the subjects of control do not overlap, their activities should be fixed at the legislative level. It is also worth bearing in mind that appropriate conditions must be created to create compensatory mecha- nisms in the financial services markets by developing a system for guarante- eing deposits and providing for payments under long-term life insurance contracts, non-state pension provisions, deposits with deposit accounts to credit unions, etс.

In and around the state-owned forest of Farako in the region of Sikasso, Mali, a large-scale study focused on finding a compromise allowing the existential and legitimate needs of the population to be met and at the same time conserving the forest resources in the long term. The first step in research was to sketch out the rural socio-economic context and determine the needs for natural resources for autoconsumption and commercial use as well as the demand for non-material forest services. Simultaneously, the environmental context of the forest and the resources available were evaluated by means of inventories with regard to quality and quantity. According to an in-depth comparison between demand and potential, there is a differentiated view of the suitability of the forest to meet the needs of the people living nearby. Propositions for a multipurpose management of the forest were drawn up. This contribution deals with some basic elements of research methodology as well as with results of the study.
