Continuing problems of transport companies in consequence of financial and economic crisis are clear-cut evidence that risk management in transport companies plays a very important role to achieve long term competitiveness and profitability. The paper is dealing with business risks and risk management in transport companies. The transport business, as a specific type of service, must take into account the many risks that arise as a result from the changing nature of external as well as internal factors of change of business environment. Transport business is one of the most problematic areas of Ukrainian business. It is important to manage and manage risks not only when
starting a business, but also as a whole conducting business activities. Business risk management is the assumption that business risks will be properly identified, evaluated and managed, and that business opportunities will be fully exploited. The purpose of this article is to consider forms of risk management in the transportation business. The process of managing business risks in a transport company is related to the scale of its activity. Transport companies are now operating in a high degree of uncertainty and exposed to various risks, making it impossible to identify any stable and
accurate process and precise solution that could guarantee the elimination or avoidance of risks. Risk management, as well as the resolution of each crisis is individual and specific. It is associated with different circumstances, is performed in different conditions and is accompanied by different events. Such a process requires extensive practical experience and professional knowledge in various fields. Currently, addressing risks and managing crisis situations is considered an important
task for every manager

This article examines the institutional foundations of the development of the tax system in Ukraine under the conditions of reform of local self-government. The expediency of the institutional approach to the analysis of the tax system development is substantiated. The main elements of the tax system in this context (formal and informal institutions, organizational structures) are highlighted. The negative aspects of the development of the tax system in Ukraine in the period of independence have been identified and the risks associated with them have been identified. The expediency
of tax reform in the context of transformational changes in the system of public administration and strengthening of local self-government is substantiated. A study of regulatory support was carried out, which had a significant impact on the development of the tax system in the context of decentralization. Some changes in the tax system for the benefit of local self-government have been identified and justified. The main legislative acts are investigated, which, having a significant impact on the reform of the local self-government system in Ukraine and the change of the territorial
organization of the authorities, are characterized by indirect influence on the development of the tax system; however, the significant impact of such acts on the efficiency and effectiveness of the tax system reform was noted. It is established that as a result of decentralization changes, a new financial basis for the development of local self-government has been formed, namely: the key role is given to taxes and fees that are levied on the territory; to give local governments the right to regulate rates and to establish privileges of local taxes and fees; there was a redistribution of national taxes and fees between budgets at different levels; the formation of the system of local
taxes and fees due to the allocation to local powerful tax sources of budget revenues; tax revenues of budgets have been expanded due to the introduction of excise tax on sales of excisable goods.

The author analyzes the features of the appearance, existence and world spread “academic capitalism”, “academic (or university) entrepreneurship” phenomena, as well as a new type of university-oriented universities – “entrepreneurial universities”. The reasons for the emergence of “academic capitalism” in the United States have been examined. It has been noted that “academic capitalism” is an intellectual, knowledge-based entrepreneurial component of the economic system of capitalism and directly affects its subsystems – productive forces, technical and economic relations, industrial relations and economic mechanism. It has been noted that academic capitalism
is a specific type of a holistic process of expanded capitalist reproduction, dissemination and consumption of new knowledge as intellectual capital and intellectual property, technics, technologies, methods and techniques for the formation of innovative means of production, the identification of new resources and innovative methods of management. The authors consider the theoretical and methodological foundations of the innovative development of higher education based on a comprehensive analysis of university (academic) entrepreneurship phenomenon. Assessment of its role in the innovative development of society and on the basis of a study of the historical cause and effect relationships of the emergence of “academic capitalism” and the development of university entrepreneurship. It has been also indicated that the causal relationship between the emergence of “academic capitalism” and the emergence of university entrepreneurship should be studied in a sequence of interrelated events and stages of development of society, science and higher education, as its components. The scheme of the process of evolution of new knowledge in the system of creating knowledge from the beginning of R&D to the commercialization has been considered. The authors’ research will be useful for the further development of national economic and entrepreneurial education, own academic (university) entrepreneurship and innovative reform of higher

The key trends of dynamics and structure of investment activity in the agroindustrial complex of Ukraine are determined. It is indicated that the most attractive type of agroindustrial complex for foreign investors is the production of food products. The tendency to decrease the level of direct state support of capital investments in the agro-industrial complex was revealed. It was established that in the types of economic activity of the agro-industrial complex in 2017, 233 investment projects were implemented accompanied by state authorities and management (national, departmental and regional levels). The proposals on improving the investment attractiveness of the agro-industrial complex are presented. Reasonable measures aimed at improving the organizational and economic mechanism of investment activity of the agro-industrial complex. The tools of stimulating investment lending in the agroindustrial complex by means of payment of budget compensations aimed at «cheapening» loans, as well as for expanding the practice of applying investment lending to the agro-industrial complex based on the use of market instruments are proposed. Promising market instruments for activating long-term (investment) lending to the agro-industrial complex have been identified, namely: support for the functioning of cooperative banks established with the participation of business entities in the agro-industrial complex; support for the creation and operation of specialized agrarian banks, which should be targeted at the priority servicing of borrowers of the agro-industrial complex; creation of the State Development Bank, which will carry
out preferential investment crediting of agricultural enterprises; stimulation of introduction of the newest credit products for the agro-industrial complex.

The article substantiates that in the context of solving the problem of improving the forms and methods of fiscal influence on the economy, planning strategic directions of fiscal policy should be based on the principles of non-discredit regulation, which is achieved if changes in tax revenues and government transfers depend on GDP. To this end, a correlation-regression analysis of the impact of GDP on tax revenues to the consolidated budget, where the results of the regression model are used to forecast the revenue side of the budget in different scenarios of economic development in a pandemic. The negative influence of factors is marked: a significant drop in
effective demand of the population; significant unemployment due to the return of workers, mass layoffs; mass bankruptcy of medium and small businesses; deep protracted recession; accelerating inflation. To build a regression model, two factors were selected that are considered as key factors influencing the dynamics of the revenue side: gross domestic product, consumer price index. The forecast was based on actual data for the period 2007-2019. The calculations showed that the growth rate of tax revenues to the budget of Ukraine will decrease significantly due to the impact
of the crisis caused by the pandemic. In particular, under the optimistic forecast, tax revenues will increase by more than eight percent in 2020, and under the pessimistic forecast will decrease by seven percent. In 2021, the gap between the pessimistic and optimistic scenarios has narrowed significantly and according to calculations, we can expect a slight increase in tax payments by twelve percent. The level of redistribution will also decrease to about twenty-five percent. It is proved that when building a model of fiscal regulation, the impact of certain types of taxes on the revenue side of the budget, in particular, personal income tax and value added tax, should be
taken into account. It is established that the crisis phenomena, accompanied by bankruptcy and closure of business entities, and hence an increase in the number of laid off employees, will lead to a decrease in budget revenues from personal income tax. The results of forecast calculations show that this source of revenue should be expected to decrease by at least ten percent, and under the pessimistic scenario
- the decline in revenues from this tax in 2020 could reach twenty percent.
It is determined that the negative dynamics of VAT revenues can be observed only in the
pessimistic scenario, and the decrease is insignificant - about five percent. Under the optimistic scenario, revenues will increase by about twenty percent in 2020 and thirty-five percent in 2021 compared to 2019. It was found that the most «vulnerable» to the crisis caused by the COVID-19 pandemic is the article of personal income tax revenues, which, accordingly, requires the development of a certain algorithm of measures to create sufficient fiscal incentives to minimize the negative consequences.
Influence of internal curing on the properties of non-fibrous high strength concrete—A critical review
Authors: Karim Ferhad Rahim
Published: February 2021

The demand for the construction of high-strength concrete in the civil engineering zone is growing, particularly in the last couple of years, due to the construction of sustainable and economic buildings with an extraordinary slim design. Concrete curing in construction is an operative manner and essential to provide that concrete structures meet future performance and durability. High-strength concrete has a low water-to-binder ratio; proper concrete curing is important to ensure its planned performance and durability. Conventionally, exterior curing applied after placing and casting concrete stays warm and moist to provide continued cement hydration. Lately, theoretically and experimentally comprehends that internal curing is an important tool to provide additional moisture in the concrete to enhance cement's hydration. Internal curing of high-strength concrete is an active technique to lessen or even remove autogenous shrinkage and effects on chemical shrinkage, dry shrinkage, etc. Most studies recently have emphasized that a reduction in high strength concrete mixtures' shrinkage is due to internal curing, and the compressive strength can increase higher in mixtures with LWA or SAP than in mixtures without this agent rising degree of hydration by providing extra water in the hydrated cement paste. However, the use of internal curing leads to improving the durability of high-strength concrete.

The leaves of khat plant (Catha edulis) are widely consumed by people of East African countries and Arabian Peninsula for their pleasurable and stimulating effects. The consumption of khat is prohibited in the Kingdom of Saudi Arabia but it is being used by the people of Kingdom, especially in the region of Jazan, where it is easily available due to its cultivation in the neighbouring country Yemen. The objective of the study was to evaluate the effect of very low doses of cathinone on the brain lipids. Male Swiss albino mice were divided in 4 groups, one control and 3 experimental and each group having 6 animals. (-) Cathinone, 0.125, 0.25 and 0.5 mg/kg body weight was given intraperitoneal to animals for 10 days, once daily.  Cathinone has elevated the level of triglyceride significantly and dose dependently as compared to control group. On the other hand, the content of ganglioside was depleted significantly and dose dependently in experimental groups as compared to control group. A significantly elevated level of cholesterol was observed with the doses of 0.25 and 0.5 mg/kg and phospholipids with the dose of 0.5 mg/kg of cathinone as compared to control group. No significant change on total lipids was observed in cathinone treated group as compared to control group. The study concludes that very low doses of cathinone were sufficient for the change on the brain lipid contents to provide excitement in khat chewers.

Authors: Palamarchuk Inna
Published: February 2021

The results of researches on studying of influence of mulching of soil on formation of a crop of plants of a zucchini in the conditions of the Right - bank Forest - steppe are resulted. The dependence of the phases of growth and development of zucchini plants, the dynamics of fruiting and yield in general on the type of mulching material was revealed. The use of synthetic mulching materials helped to reduce the interphase periods, increase yields and the percentage of early and late harvest. Mulching materials of organic origin extended the interphase periods. Thus, the shorter germination period - the beginning of fruit formation was by mulching the soil with perforated black polyethylene film and black agrofiber, which is 5-8 days shorter than the control, respectively. The longest harvest of zucchini was carried out on options for mulching the soil with black agrofiber and perforated black polyethylene film, depending on the variety, the duration of fruiting ranged from 67-85 days with the value of this indicator in the control 72-77 days. The highest yield was obtained by mulching the soil with perforated black polyethylene film, where the increase relative to the control was 10.9 - 28.0 t / ha, respectively. The highest percentage of harvested early products was provided by options for mulching the soil with black agrofiber and perforated black polyethylene film at the level of 6.6-8.3% in 2016 (control - 0.8-4.1%) and 3.2-5, 0% in 2018, while in the control versions the collection started a decade later. The most intensive fruiting of zucchini was observed from the first decade of July to the first decade of August for all years of research.

Authors: Mudrak Halyna , Mudrak Oleksandr
Published: February 2021

The necessity of studying the current condition of agro-landscapes of Middle Transnistria in the context of the strategy of sustainable development of rural territorial communities of the region has been analysed. After all, ecologically safe use of agroecosystems of any region should become one of the necessary conditions for ecologically balanced development of its agrosphere. The authors note that the current condition of agro-landscapes has been characterized by significant diversity and complex landscape-typological structure. The differences of agro-landscapes in economic use have been presented, which led to the allocation of such subclasses: field, meadow-pasture, garden.
The authors used different approaches and methods to study the modern agricultural landscapes of Middle Transnistria. The most significant were general scientific and specific scientific approaches. Among them the following were used: traditional or classical (comparative, historical, genetic, evolutionary) and specific (constructive, socio-economic, systemic, ecological, landscape-typological, informational, sociological) research approaches. Among the research methods most used: systemic, genetic, cartographic, morphometric, predictive and comparative.
It has been established that the economic use of different subclasses of agrolandscapes of the region depends on the climatic, hydrological, orographic, edaphic and landscape-ecological conditions of the region.
The characteristics of garden landscapes have been determined, which are located mainly on steep slopes, leveled terraces of river valleys, territories of former field landscapes. Location on the appropriate types of areas, species composition of plantations and specific agronomic regime, determine the formation of these unique garden landscapes. Here certain favorable microclimatic conditions, plant and animal groups which are inherent in specific garden landscape complexes are created. Among them are unique palmette orchards and those within which there are rare and adapted to the natural conditions of the region varieties of fruit trees.
The uniqueness of the garden landscapes of Middle Transnistria is considered on the example of a natural area near the village. Dmytrashkivka, Vinnytsia region, where valuable plots of palm gardens are located.
A set of measures proposed to promote the rational use of agricultural landscapes of Middle Transnistria in the context of implementing strategies for sustainable development of the region
ECOLOGICAL STABILITY MAIZE HYBRIDS RELATIVELY GRAIN YIELD IMPORTANT CONDITION INCREASE IN GROSS PRODUCTION
Authors: Cherchel Vladyslav , Stasiv Oleh , Bodenko Natalya , Kupar Yuliya
Published: February 2021

The relevance of the conducted scientific analysis of long-term data of the competitive test of the State Institution Institute of Grain Crops of the NAAS, regarding the grain yield of maize hybrids, is due to the problems of climate change that has been observed. Due to an increase in air temperature and a long without a frosty period, corn is not only guaranteed to ripen in the Steppe, with timely sowing and harvesting, but also has a harvest moisture content of grain close to the base. Corresponding climate changes motivated the rapid expansion of the territory of corn cultivation in Ukraine, an increase in acreage, gross production, and grain yield of this crop. However, the dangers caused by stress factors of the flight period are increasing, which focuses on the problem of creating hybrids that are resistant to the extreme conditions of the northern Steppe. Due to the determination of the parameters of the tolerant types, models of hybrids were formed and recommended for use in production in the conditions of various ecological territories of Ukraine. The article discusses the results of the progress of the yield of corn hybrids due to breeding improvement, reflected in changes in the actual indicators of grain harvest and harvest moisture of grain caused by climate change and their impact on the elements of crop cultivation technologies. It was determined that under stressful conditions, the grain yield of maize hybrids decreased by an average of 2.9 t / ha, and the harvest moisture content of the grain increased by 1.6%. It was also noted that over the past 25 years, the yield of corn grain in the test, on average for a five-year period, increased from 5.69 (1995-1999) to 7.14 t / ha (2016-2020) with a decrease in the harvest moisture content of grain from 22.4 to 16.1%. In the discussion of the research results, the regularities of the formation of the trait "drought resistance" of hybrids are revealed, the genetic and agrotechnological components of the formation of the trait, their influence on the characteristics of crop cultivation are distinguished. As a result, the value of a hybrid with an average but stable grain yield, which is determined by economic feasibility, is proved, in comparison with high-intensity forms, which are characterized by significant fluctuations. In order to obtain high and stable yields of corn grain in each farm, it is necessary to plan the varietal structure of crops with an assortment of hybrids that have a diverse type of reaction to the variability of environmental conditions.
INFLUENCE OF THE LEVEL OF WATER MINERALIZATION ON THE CONCENTRATION OF HEAVY METALS IN MUSHROOMS
Authors: Vradiy Oksana
Published: February 2021

The current ecological condition of forest plantations has been characterized by high anthropogenic load as a result of population activity. The consequences of the human impact have been manifested in the disturbance of natural landscapes, air pollution, hydrosphere, destruction of the lithosphere, uncontrolled depletion of forest resources, resulting in a decrease and extinction of a huge number of species of animals and plants. In the result of various industries’ work chemical compounds have been formed, which have been transformed into the biosphere and enter all living organisms. Therefore, there are serious problems in the relationship between nature and man. The human impact on the environment is extremely powerful and it is obvious that the biosphere as a result of this impact loses the ability to self-regulate and it does not allow it to function properly.
One of the current environmental problems that threatens plants, animals and human health and the quality of the environment is heavy metal pollution. These substances gradually enter plants, animals and humans through the air, water and food chain over a period of time [4]. Toxicity of metals has a direct effect on flora, which is an integral part of ecosystems. These effects lead to changes in the biochemical, physiological and metabolic processes that take place in plants that grow directly in areas with high levels of heavy metals. Samples of edible forest mushrooms were taken on the territory of forests of Tyvriv, Vinnytsia and Kalyniv districts in the Forest-Steppe of the Right Bank of Ukraine. Studies of the concentration of heavy metals were performed in the research and measurement agrochemical laboratory of the Department of Ecology and Environmental Protection, Faculty of Agronomy and Forestry on the basis of Vinnytsia National Agrarian University. The concentrations of Cu, Zn, Pb and Cd of the studied fungi were determined by atomic absorption spectrometry after dry mineralization. Studies of the effect of cooking on the concentration of heavy metals in mushrooms were carried out according to the following scheme: 1. control option: mushrooms, cleaned and washed with tap water; 2. option 1: mushrooms soaked for 3 hours in water without mineral residue; 3. mushrooms soaked for 3 hours in water without mineral residue with the addition of salt (1 kg of mushrooms – 1 liter of water and 10 g of salt).
The effect of soaking mushrooms in water without mineral residue with the addition of salt was studied. It was found that when soaking mushrooms for 3 hours in water without mineral residue, the concentration of zinc in them decreased: from

Published: February 2021

In current conditions of agricultural production with intensive technologies of growing crops, fertilizer is one of the most expensive elements of agricultural machinery, as experienced agricultural experts say that the food system should be optimized.
In recent years, biological preparations of various action mechanisms are in increasing demand among farmers. Particular attention is paid to mycorrhizal biopreparations, one of which is "Mykofriend" and preparations based on phosphorus and potassium mobilizing bacteria "Groundfix". Preparations stimulate the development of beneficial soil microorganisms, help preserve and increase soil fertility, activate its suppression against phytopathogens, improve productivity in crop yields, including sunflower.
This article presents important aspects of the technology of growing sunflower with a variety of applications of biological origin, which optimize the process of plant nutrition through better use of mineral elements and improve growth processes. New perspective biological preparations, manufactured by BTU Center, for pre-sowing seed treatment and soil application were studied.
It was found out that the treatment of seeds with mycorrhizal drug Mycofriend with the rate of 4 l / t and when applying pre-sowing cultivation of biological fertilizer Graunfix at a rate of 8 l / ha contributed to the formation of the best conditions for plant growth and development, and as a consequence of the best
productivity parameters. In this variant, the maximum plant height of 189.3 cm, leaf surface area of 30.9 thousand m2 / ha (flowering phase), dry matter yield in the ripening phase of 5.28 t / ha, basket diameter of 23.1 cm, weight of 1000 seeds is 49.6 g and seed yield is 2.84 t / ha.

Background. Behçet's disease is a rare systemic autoimmune vasculitis. The presence of infection makes it difficult to manage. Case. Ms. X, 19 years old, complained of mouth and genitalia ulcers and joints pain. She had typhoid fever two months before; and a week after recovery, she experienced reddish skin lesions on her legs. Her condition was weak and the pain visual analog score (VAS) was 9/10. Multiple oral ulcers were found in her oral cavity and vulva. Her lungs were hypersonor. There were hyperpigmented maculae in her lower extremities. Her ankle joints were painful in passive and active movements. Blood leukocytes: 13,210/µl, urine leukocytes: 20-23/hpf, ANA, anti-dsDNA and Pathergy tests were negative. The diagnosis of Behçet's disease was based on multiple oral and genital ulcers, history of erythema nodosum and arthritis. The patient was treated with topical triamcinolone. Joint ulcers and pain worsened; so that intravenous methylprednisolone was administer. Two days later, the patient had cough and oxygen desaturation. Chest X-ray showed emphysematous lungs and pneumonia. Methylprednisolone was stopped, ceftriaxone and levofloxacin were given, treatment for ulcers and arthritis was replaced with colchicine and rebamipide. Sucralfate is given for gargle and applied to the genital ulcers. On the seventh day, the ulcers were greatly reduced, joint pain resolved, cough subsided and VAS became 2/10. On the twelfth day, the chest X-ray was normal and ulcers were healed, ankle pain was suffered again accompanied by swelling. The patient was treated with methylprednisolone and azathioprine. Discussion. Treatment for this disease is immunosuppressants. In severe conditions with infection, colchicine can be an alternative treatment. Adjuvant treatment are rebamipide and/or sucralfate. Emphysematous lungs can be caused by alpha-1 antitrypsin deficiency or pulmonary vasculitis, which can be manifested in autoimmune diseases. Emphysematous lungs, leads us to follow up on the development to other autoimmune disorders such as lupus. Conclusion. Behçet's disease with infection can be successfully managed with colchicine, rebamipide and sucralfate.

A B S T R A C TSystemic lupus erythematosus (SLE) is a chronic systemic autoimmune diseaseand can attack almost all organs and tissues of the human body. Beside geneticfactors, environmental factors are thought to play a role, such as ultraviolet light,viral infections and smoking, causing a breakdown of self-tolerance which cantrigger an autoimmune response. The study was conducted in the outpatient andinpatient units of the Rheumatology Division of the Department of InternalMedicine Saiful Anwar General Hospital/Faculty of medicine UniversitasBrawijaya, Malang. Subjects were female patients, aged > 18 years who had beendiagnosed as SLE by internist-rheumatologist based on the 1997 ACR criteria, withSLEDAI score > 3. After 3 months of supplementation, there was a significantdecrease in serum levels of the three pro-inflammatory cytokines (IL-6, IL-17, IFN-gamma), as shown in table 3, compared to before treatment, as well as anti-dsDNA levels.Serum TGF-beta1 levels increased significantly, while 25 (OH) D3 levels also increasedsignificantly.

A B S T R A C TSystemic lupus erythematosus (SLE) is a chronic, inflammatory,autoimmune, multisystem connective multi system connective tissuedisease characterized by various autoantibodies to nuclear and cytoplasmicantigens and commonly affects the joints and a variety of organs due to anover activation of the body's immune system. There is wide heterogeneity inpresentation of SLE patients, including lung, central nervous system, skin,kidney, and hematologic manifestations. The presence of antinuclearantibodies (ANA) in serum is generally considered a decisive diagnostic signof SLE. However, a small subset of SLE patients who had the typical clinicalfeatures of SLE was reported to show persistently negative ANA tests. Ourreport describes a 24-yr-old female who presented with the clinicalmanifestations of SLE such as malar rash, photosensitivity, arthritis, oralulcer, and proteinuria. The serum autoantibodies were all negative exceptanti ribosomal P. She was also positive for lupus anticoagulantanti -coagulant. She was treated with oral prednisolone , hydroxychloroquinewith topical tacrolimus, and improved significantly. Three months after,repeat ANA, and anti-ds DNA showed persistent negativity, but lupus anti -coagulant remained positive. This case suggests that ANA may not berequired in the pathogenesis of SLE.
