Impact of Celebrity Endorsement and Breaking News Effect on the Attention of Consumers
Authors: Lazar Laura , Pop Mihai-Ionuţ 
Published: July 2021

Abstract
In the last decade, the new means of communication have determined substantial changes in human behavior and in the way individuals interact with each other. Besides the numerous benefits and opportunities that have arisen throughout the digitalization process, both for individuals as well as for private companies and state institutions, the widespread use of the Internet has generated vulnerabilities and threats. One of the most consistent concerns related to the new means of communication, especially social media platforms, refers to fake news. In recent years, major events including the 2016 presidential election in the US, Brexit, and the emergence of the COVID-19 pandemic have proven the negative effects of fake news on society.
In this paper, we use an eye-tracking experiment to determine the unconscious reactions of consumers regarding the attraction potential of a fake news manner written article about a celebrity couple. The results of the experiment for this magazine’s article, with a fake title about the celebrity couple, show that the participants focus their attention on celebrities and fake titles mostly. The picture of the celebrities and the fake title of the article beats the other areas from the article and less on the information in the text. The research proves empirically that consumers are more attentive to celebrity pictures and fake breaking news titles and less to real information in the article. To sum up, testimonials and fake news play an important role in attracting publicity and influencing consumer behavior.
Analysis of Impact of Changes in IFRSs on Convergence of Accounting Systems in World

Published: July 2021

Abstract
The article examines the impact of updated IFRS on the current convergence of national accounting and reporting rules in Japan, the USA, China, France, Germany, the UK, and Ukraine based on a theoretical analysis of 59 rules and concepts of IFRS. The new differences between the updated IFRS and GAAP of these countries based on the comparative analysis were revealed. The results of the study show currently Ukraine (51%) and the United Kingdom (47%) are the most convergent with IFRS, although their degree of convergence has decreased significantly after recent innovations in IFRS; a new question arises for the UK after Brexit regarding the further application of IFRS; countries with strong national accounting traditions continue to avoid rapid changes in their GAAP; 4) the increase in the convergence of GAAP Japan with IFRS will not be possible shortly. The conclusion states that the main obstacle in the convergent process GAAP and IFRS is that: 1) IFRS are changing based on GAAP USA, rather than vice versa; 2) IFRS do not belong to the “stable to change standards”, so users have a certain distrust of the declared high quality of IFRS. The study results add significant novelty to scientific and practical research on the impact of frequent changes in IFRS both locally and internationally.

Impact of Biogenic Amines on the Growth of a Chlorella vulgaris Culture
Authors: Oleskin Alexander V. , Postnov Andrey L. , Boyang Cao 
Published: July 2021

The present work aims to develop a new approach enabling biotechnologists to increase the yield of Chlorella vulgaris biomass by means of biogenic amines (serotonin, dopamine, and histamine) that are known to stimulate growth of various unicellular organisms. C. vulgaris strain ALP was cultivated in the light with constant aeration at 24oC in a minerals-containing medium. Experimental systems contained 1, 10, or 100 mM of dopamine, histamine, or serotonin. Algal cells were counted using a light microscope. Serotonin caused a slight increase in biomass yield at a concentration of 10 mM, but not at the other tested concentrations. 1 and 10 mM (but not 100 mM) dopamine increased the cell number in the C. vulgaris culture at early cultivation stages. Histamine is the most efficient growth stimulator at concentrations of 1 and 10 mM, but not at a concentration of 100 mM, which even proved inhibitory to the algal culture. The data obtained demonstrate that the neurochemicals exert a stimulatory influence on the growth of the Chlorella culture at relatively low (micromolar) concentrations. Since animals often produce biogenic amines in response to stress or injury, the data give grounds for the suggestion that planktonic algae can benefit, in terms of growth rate, from the substances released by stressed or wounded representatives of aquatic fauna. In biotechnological terms, the data obtained hold some promise with regard to developing a relatively economical technique of boosting Chlorella biomass production.

Published: July 2021

Based on the results of observations, it was specified that when decreasing soil moisture there is a disproportionate decrease in the average daily evapotranspiration (ET). Thus, in the range of soil moisture of 94-80% minimum moisture-holding capacity (MMHC) ET was 9,76 mm a day, and in the range of 70-62% MMHC - its value decreased by 3 times. When the soil moisture reached 58,5% MMHC, the value of ET did not exceed 0,5 mm a day, which is 20 times less than the initial one. It was determined that the decrease in soil moisture by 10% in the range of 90 - 70% MMHC occurs during 3 days, and from 70 to 60% MMHC and from 60 to 58% MMHC - during 8 days. When soil moisture is 70% MMHC and below, the actual evapotranspiration is less than ETo that proves the effect of water stress on soybeans ET. When calculating water stress coefficient (Ks), a mathematical model based on the dependence of Ks on soil moisture as a percentage of MMHC was obtained. The average absolute percentage error (MAPE) is 8,6%, which corresponds to the high accuracy of the obtained dependence. In the range of soil moisture from 58 to 80% MMHC, the water stress coefficient is calculated by the formula Ks =-0.0011·FC²+0.1925·FC-7,4541. When having soil moisture as 80% MMHC and above, Ks = 1. A comprehensive comparative assessment of existing methods for calculating waster stress coefficient Ks was taken and it was found out that the actual values of Ks when having soil moisture as 80-70 and 60-65% MMHC by 8-14 % and 72-32 %, respectively, less than Ks FAO 56, and by 35-40 % larger than those determined by Saxton method. It was proved the need of taking into account the reduction in evapotranspiration when calculating water balance under water stress of plants. The calculation of evapotranspiration (ETs) by the Penman-Monteith method, without taking into account the water stress coefficient, showed that the value of the actual and calculated water balance coincides only when soil moisture does not exceed 62% MMHC. With a further decrease in soil moisture, the estimated soil moisture was 20% less than the actual, which led to the errors in determining soil moisture after irrigation, because its actual value was almost 100% MMHC, and the estimated one was only 60% MMHC. It was proved that the determination of water balance by calculation methods without taking into account the water stress coefficient leads to significant errors.

Cultivation of nightshade family crops (Solanaceae) requires sufficient amount of moisture and heat. In Ukraine, the most available conditions for that are in the southern regions: Kherson, Mykolaiv, Odesa, Zaporizhia and AR of Crimea, where the average yield of tomatoes is about 30 t/ha, and planting area is about 470 thousand hectares. Tomatoes are the main host plants for the South American tomato moth. Leaves, fruits and vegetative buds damaged by these pests, become a kind of «gateway» for the infection of plants by fungal pathogens. Feeding of phytophagous on the fruits of tomato leads to their falling off. Yield losses can reach 100%. This pest has high adaptability to climatic and natural conditions, capable for reproductive activities throughout the year. Among the factors contributing to the spread of these pests at the intercontinental level, the most important is the uncontrolled trading of infected fruits with plant particles, and the local spread from one field to another due to the ability of adult moths to fly. The searching of scientifically grounded methods of control of South American tomato moth, in particular, the study of the effectiveness of modern insecticides by means of spraying and drip application along with applying irrigation against this pest in the Steppe of Ukraine is very actual.
During the phytosanitary evaluation of experimental plots of tomatoes before treatment with insecticides, a high number of larvae of South American tomato moth was found, which in the check plots averaged 3,1-7,0 number/plant before the first application of insecticides, and 9,1-20,6 number/plant before the second one. Insecticide Exirel, SE (cyantraniliprole 100 g/l) with the consumption rates of 1,0 l/ha and 1,5 l/ha when providing double spraying in a small-plot experiment on open ground tomatoes provided the effectiveness against tomato moth caterpillars at 91,1% and 99,5% on the 3rd day after application, and the duration of its toxic effect exceeded 14 days. In the conditions of protected soil when applying the insecticides along with drip irrigation the insecticide Verimark CS (cyantraniliprole, 200 g/l) with the rates of 0,5 and 0,75 l/ha provided the effectiveness against tomato moth caterpillars in 3 days after application on the average by 92,4-100,0%, and the duration of its toxic effects was more than two weeks. Applying insecticides along with drip irrigation due to their local application provided high efficiency of insecticides against phytophagous larvae, having a rather long duration of toxic effect, compared with spraying.

Research relevance. Climatic changes determine the need to ensure a high productivity of drained lands through the use of appropriate adaptive measures for regulating and accumulating moisture in the soil. Therefore, the issue of changing approaches to the creation and operation of water reclamation facilities on drained lands gains relevance. Relevant are also changes in the methodology of projects for drainage systems construction and reconstruction and their optimal design solutions (type, design, systems parameters, and components of their technical elements) in the closed collecting and drainage network. In this case, the closed collecting and drainage network is a key element of the drainage system, which can operate in the drainage and soil moisture regime.
Aim of the study is to reveal new approaches to improving the methods of dimensioning the closed collecting and drainage network of drainage systems operating in the regime of drainage and soil moisture, based on justifying the relationship and considering the impact of network efficiency on the efficiency of water regulation on drained lands.
Research methods. The analysis and generalization of the existing researches and methods on justification of the type, design, and parameters of the closed collecting and drainage network in the regime of drainage and soil moisture of the drained lands is executed. Systems approach and systems analyses were used to determine the existence of a structural relationship between the operation regime of the closed collecting and drainage network and the water regime of the drained lands. In performing the theoretical research, methods of mathematical modeling of the hydrodynamic structure of turbulent flow in pressure pipes using Navier-Stokes differential equations were applied. To confirm the adequacy of the obtained analytical models, the methods of statistical processing of experimental research results by Nikuradze I., Shevelyov F.O., and Altshul A.D. were used.
Research findings and main conclusions. Thus, based on the performed theoretical and experimental research, we have proposed relatively new scientific positions in contrast to the semi-empirical theories for determining the hydrodynamic structure of the flow in the pressure pipe. This allows for dimensioning the entire hydrodynamic structure for all areas of the turbulent flow based on the application of the obtained universal equations. That is, we can construct a distribution profile of the total turbulent kinematic viscosity, averaged velocity, tangential stresses, and angular velocities of fluid particles.
Prospects. The presented approach will make it possible to determine the efficiency of flow in drainage pipes and in a closed collecting and drainage network. Also, this approach will further be helpful in improving the methods of designing and dimensioning technological and structural parameters of the network and ensuring the overall technical, technological, economic, and environmental efficiency of drainage systems.
Specifying the parameters of the Kamianske Reservoir

Published: July 2021

The relevance of research is the lack of actual parameters of the Dnipro Сascade.
The purpose and objectives of the study are to specify the actual parameters of the Kamianske Reservoir, which is the part of the Dnipro Cascade.
Methods and techniques. The study was based on using the actual Navigation map of the Kamianske Reservoir. The available data were processed when using AutoCAD program. The satellite images were used as well.
Results and main conclusions. It was identified that the main parameters of the Kamianske Reservoir, which is the part of the Dnipro Cascade, significantly differ from those obtained earlier, in particular, which are given in the operation rules of the Dnipro Сascade. The most important parameters of the Kamianske Reservoir to keep normal retention level (64.0 m) are as follows: water area (water surface) – 537 km2, total volume – 2636 million m3, useful storage capacity – 495 million m3. A small increase in the total volume compared to the project one is supposed to be the result of significant extraction of construction raw materials from the bottom of the reservoir. The reservoir length, depending on the ways of measuring, varies from 119 to 137 km. It was determined that the actual maximum depth of the reservoir (23 m) is significantly larger than it is indicated in reference books. The actual average depth of 5.8 m is significantly larger as well.
Some parameters of the reservoir, which were previously ignored by researchers, are given as a result of the study. This parameter, in particular, is the area of the islands, which is 48.9 km2. The area of shallow water with depths less than 2 m is 152.4 km2. This area is mainly located in the upper and middle parts of the reservoir – mainly near the left bank. An important parameter is the cross section of the central reach of the reservoir, where the main movement of water is observed. Depending on the length of the reservoir, this cross-section varies in the range of 17,900–20,600 m2. The smallest cross-section is a characteristic feature of the upper part of the reservoir that causes an increase in flow velocity above 1.0 m/sec. It was concluded that the existing operation rules of the Dnipro Сascade does not correspond to the present and require the radical improvement. A mandatory requirement for the new rules is specifying the modern parameters of the reservoirs, built on the Dnipro River. Perspectives. There is need to specify the parameters of all reservoirs of the Dnipro Сascade. It is a basis for the development of new operation rules for the Dnipro Сascade.

The balance method of determining the share of Kryvyi Rig Basin enterprises by the accumulated volume of mine water in the storage pond was considered. The balance method of participation of mining enterprises by the shares of mineral substances was formalized. An integrated approach of the control of water removal into the storage pond when using linear convolution of two balance equations by both the share of water volumes and the mineralization rate in the water discharges of enterprises was developed. It takes into account the choice of equity participation in mine water removal by economic and environmental criteria.
The algorithm of equity participation of mining enterprises of Kryvyi Rih Basin on the principles of equality of two criteria was substantiated. The calculations of the share of discharge water accumulation in the storage pond of the Svistunov gully were carried out. The estimated price for water removal of one cubic meter of water into the storage pond by two criteria was considered. The estimation criteria are the volumes of pumped water and mineralization rate. Graphical dependences of the estimated price on the ratio of discharges concentration of different enterprises to the mixture concentration were built. Different estimation coefficients were used: paid water removal by water volumes; assessment of water removal only by mineralization rate; equal approach by the volumes (50%) and mineralization rate (50%). The calculations showed the efficiency of the algorithm, the applicability of its use by enterprises for integrated control of mine water removal by the criteria of volume and mineralization rate.
The proposed balance method can be easily generalized when using other indicators of water quality (chlorides, sulfates, etc.), which are considered to be the most relevant for determining the equity participation of enterprises. In the future it is necessary to develop a theory of paid water use and water removal in conditions of unsatisfactory water quality, taking into account the integrated approach by different indicators that means multi-criteria assessment of water removal and accumulation of mine water.
