Annotation. The priorities of business development of business enterprises through incentives and motivation are substantiated. It is established that the motivational mechanisms of any enterprise should be built with the participation of state and regional government and take into account the interests of employees. The connection between staff motivation and financial incentives is determined. The imbalance of remuneration of personnel of different professional categories on the example of energy workers is theoretically and practically substantiated. The system of remuneration of workers in the energy sector has been studied. It is substantiated that with a constant subsistence level for able-bodied persons and an increase in the minimum wage, there will be a further leveling of the prestige of professions and a disparity in wages. The legal framework for the system of remuneration and motivation of staff is analyzed and it is established that the business economy of the enterprise should be based on the principles of effective system of interaction between the state and the region, strengthening ties between other business structures and developing a rational incentive mechanism. The research conducted in this article makes it possible to form a vision of the irrational system of motivation of employees of different categories and the need for state regulation of a holistic set of tasks and goals for the effective functioning of business. The business economy of the enterprise should be based on the principles of effective interaction between the state and the region, strengthening ties between other business structures, as well as developing a rational motivational mechanism, which is supported by constituent documents at the government level and takes into account the interests of employees and owners. Such a system will help to solve the main problems in personnel management at the enterprise and with the correct interaction of motives and incentives will be interdependent elements of the overall development of business, region and state

The article presents an analysis of live births and abortions with confirmed Down syndrome (DS) in Kyiv in 2018-2020. During this period, 86 children with DS were born in Kyiv, which corresponds to an average frequency of 8.6 per 10,000 live births. The frequency of births of children with DS decreased from 10.4 in 2018 to 6.5 in 2020 per 10,000 live births. The percentage of male probands is 59 %, and female – 41 %. Timely diagnosis of DS in live births allows for surgical correction in the presence of congenital malformations and reduces mortality in early childhood.
Diagnosis of DS at the prenatal stage allows doctors to make decisions on abortion at the request of the woman. The analysis of cases of abortions for the period 2018-2020 shows a tendency to increase the number of aborted pregnancies. The rate of abortions with DS in Kyiv was 40 % in 2018, in 2019 – 52 %, and in 2020 – 67 %. and reached the mark of Western Europe. The high rate of aborted pregnancies correlates with a decrease in the number of births of children with DS during this period. The data show an increase in public awareness of hereditary pathology, an increase in referrals to a geneticist and an increase in the effectiveness of prenatal diagnosis.
During the period: 2018-2020, there is an increase in medical coverage; genetic counseling; and invasive interventions to establish the karyotype in high-risk women who were included in the high-risk group as a result of combined prenatal screening or had been diagnosed with birth defects or have ultrasound markers of chromosomal pathology. It is established that this pathology occurs in mothers of any age, not only in women over 35 years, which indicates the feasibility of mass use of prenatal diagnosis in all age groups.
The presented statistical data makes the case to use prenatal testing and how to rationally distribution financial resources. The prospect of further research is to analyze cases of live births and abortions with confirmed DS at the national level.
On the Asymptotics of the Schrödinger Equation Solutions and the Euler Model of an Ideal Fluid
Authors: Хаблов Владислав 
Published: December 2021

In this paper we analyze the asymptotics of the Schrödinger equation
solutions with respect to a small parameter ~. It is well known, that short-
waveasymptoticstosolutionsofthisequationleadstothepairofequations—
the Hamilton–Jacobi equation for the phase and the continuity equation.
These equations coincide with the ones for the potential flows of an ideal
fluid. The wave function is invariant with respect to the complex plane
rotations group, and the asymptotics is constructed as a point-dependent
action of this group on some function that is found by solving the transfer
equation. It is shown in the paper, that if the Heisenberg group is used
instead of the rotation group, then the limit of the equations solutions with
~ tending to zero leads to the equations for vortex flows of an ideal fluid in
a potential field of forces. If the original Schrödinger equation is nonlinear,
then equations for barotropic processes in an ideal fluid are obtained.

Published: December 2021

El presente trabajo consistió en evaluar la posibilidad del uso de dos cepas de Trichoderma harzianum (Th118 y Th5cc) sobre la manifestación del marchitamiento y cancro bacteriano del tomate en plantas de tomate platense cultivadas en invernáculo. Ambas cepas se aplicaron al sustrato de la plantinera en forma sólida (S) y líquida (L) en el momento de la siembra. Clavibacter michiganensis subsp. michiganensis se inoculó en el momento del desbrote mediante una pequeña incisión en el tallo principal entre la quinta y sexta hoja. El ensayo se repitió durante dos años consecutivos. Para cada tratamiento se evaluaron los componentes del rendimiento (peso y número de frutos) y número de hojas afectadas. Si bien no se encontraron diferencias significativas entre tratamientos durante los dos años, el tratamiento Th118 L es el que presentó menor cantidad de hojas afectadas y valores promedio más altos de peso de frutos. De acuerdo con los resultados obtenidos, se puede afirmar que la cepa de Trichoderma harzianum Th 118 aplicada como riego a los plantines en el momento de la siembra, podría ser incorporada como una buena alternativa dentro de un plan de manejo integrado de enfermedades en el cultivo de tomate platense.

O estudo teve o objetivo caracterizar os frutos e sementes da Passiflora cristalina Vanderpl. & Zappi., bem como avaliar a influência da fermentação da mucilagem na germinação das sementes e crescimento inicial das plântulas, este estudo foi desenvolvido em populações nativas do município de Alta Floresta, MT. Os frutos foram coletados na fase final de maturação e o comprimento do fruto, largura do fruto foram medidos, assim com o peso de cada fruto e o peso da semente também foi avaliado. A morfometria das sementes de P. cristalina foi obtida a partir de sementes escolhidas aleatoriamente entre todas as sementes dos frutos coletados da espécie, sendo que o comprimento e a largura da semente foram mensuradas. Para avaliar a influência da fermentação da mucilagem na germinação das sementes, foi realizado experimento com cinco tratamentos, para o primeiro tratamento (T1) a remoção do arilo foi feita com fricção em peneira de malha plástica, os outros tratamentos constituiram-se de sementes colocadas junto com a polpa em placa de Petri, variando apenas pelo tempo de fermentação: tratamento 2 (T2–48 h), tratamento 3 (T3–72 h), tratamento (T4–96 h) e tratamento (T5–120 h). Os dados obtidos foram submetidos à análise de variância. Em seguida, submetidos ao teste de Tukey a 5% de probabilidade pelo programa estatístico SISVAR. As diferenças encontradas entre os valores mínimos e máximos das características analisadas neste estudo, representam um indício da alta variabilidade genética populacional, e pode permiter uma exploração de parâmetros buscando a manutenção de áreas com populações da espécie, além de auxiliar o melhorista a realizar a introgressão de alelos favoráveis encontrados em espécies silvestres, como resistência a doenças, autocompatibilidade e redução do androginóforo, por intermédio de cruzamento interespecífico. P. cristalina apresentou menor taxa de emergência, assim como outras espécies silvestres.

Published: December 2021

Abstract
A dual-circularly polarized traveling wave antenna based on linear polarization array with wideband response is proposed. The circular polarization is realized by the sequential rotation arrangement of four linear polarization elements and series feeding with a phase difference 90°. Rotating four of such subarrays sequentially with a phase difference of 90° not only broadens the axial ratio (AR) bandwidth but also corrects the pattern beam deflection. Left-handed circular polarization (LHCP) and right-handed circular polarization (RHCP) are respectively achieved by exciting two different ports. The measured impedance bandwidth of the developed antenna array is 27.5 %. The 3-dB AR bandwidths of RHCP and LHCP are respectively 20.7 % and 22.4 % with the peak gains of about 8.7 and 8.3 dBic.

Published: December 2021

Abstract
The light-emitting diode (LED) is an essential component of intelligent street lighting (ISL) systems. An efficient ISL system can not only reduce power consumption by planning LED illuminating time but also reduce maintenance costs through a high degree of automation. In this paper, a buck-boost converter is used to realise composite transmission of power and signals for an ISL system. The power is modulated by the pulse width modulation (PWM) approach, and the switching ripple generated in the PWM process is utilised as the carrier of the signals transmitted between the remote-control centre and the slave nodes. Moreover, the proposed model involves a ‘request to send (RTS)/confirm to send (CTS)’ mechanism to avoid signal conflicts. Compared with the conventional power line communication (PLC) approach, the proposed transmission scheme has the advantages of simple circuit structure and simple system wiring. Additionally, a simulation model built in MATLAB/Simulink proves the designed transmission method has strong anti-noise ability.

Abstract
The article presents an analysis of known developments on creation of sieve-less pneumatic vibration centrifuges separating devices and processes of separating seed mixtures into fractions according to the complex of physical and mechanical properties of components. Mechanistic and mathematical models for studying the movement of particles over the sieve-free surface of pneumatic vibration separators were developed, theoretical studies of movement of seed mixture components were conducted and the most acceptable pneumatic vibration centrifugation process was determined by likeness to the process occurring on the separating surface of pneumatic sorting tables. To achieve the greatest separation of particles on the complex of their physical and mechanical properties (density, geometric dimensions, aerodynamic properties of seeds) is possible with the same direction of oscillatory motion and rotation of the separating surface performing the rotation in the direction from a larger radius to a smaller radius of the surface, in the “fluidization” mode, i. e. i.e. with periodic separation of the lower particles of the layer from the separating surface at simultaneous blowing of the layer by an air stream.

The aim of the present study is to assess The Effect of Company Size on the Relationship between Corporate Governance and Corporate Performance in the Iraqi Stock Exchange. The statistical population under study is listed companies of Iraq Stock Exchange and the number of companies studied in Iraq is 35, from 2015-2019. The results concluded that there is a statistically significant relationship between the change (increase) of institutional ownership and the performance of the company, and this relationship is direct, as well as the relationship between the change (increase) of institutional ownership and the performance of the company. It can change under the influence of the company's size, and this relationship is negative, meaning the larger the company's size, the weaker the relationship. At the same time, the existence of a relationship between changing the composition of the members of the Board of Directors and the performance of the company was not supported, as well as between changing (increasing) the independence of the Board of Directors and the performance of the company, in addition to the relationship between changing the composition of the Board of Directors. The independence of the Board of Directors and the performance of the company is not affected by the change in the size of the company

Published: December 2021

This research presents indicators that were used In estimating the independence of the Central Bank of Iraq, which distinguish between the law independence (de jure autonomy) and the actual independence (de facto autonomy) for the three central bank governors for the period 2003-2017, through the turnover rate index of governors (TOR). The research also provides a new indicator of the turnover rate of members in the executive authority in Iraq for the same period, and the effects on inflation. The study also outlines a set of behavioral indicators ​​for governors that highlight the effects of actual independence on inflation.
The main findings of the research were that the actual independence, in terms of the turnover rate index, gradually decreased for the research period, but the behavioral indicators of the governors showed that they maintain price stability. Therefore, the study presents evidence on the effect of the actual independence on inflation, because of the control of the exchange rate through the foreign currency auction and the decline of foreign reserves.

Hidrelétricas no Brasil - da invisibilidade indígena a um licenciamento socioambiental plural
Authors: Assirati Maria Augusta 
Published: December 2021

O ciclo de energia, também no Brasil, tem sido defendido como indispensável ao crescimento econômico, perseguido como sinônimo de desenvolvimento, segundo uma concepção excludente de componentes sociológicos e culturais. Os empreendimentos hidrelétricos geram inúmeros impactos ao ambiente e Ã s comunidades de seu entorno. A região amazónica, onde se pretende implementar grande parte dos aproveitamentos hidrelétricos, é marcada pela presença de forte diversidade sociocultural, inclusive de povos indígenas, o que exige políticas específicas no âmbito dessas relações. A legislação referente ao licenciamento desses empreendimentos, contudo, é produto da atuação monocultural do Estado, desconsiderando a necessidade de práticas específicas para efetiva garantia da sobrevivência física e cultural dos povos indígenas ante a pretensão de tais intervenções. Esse artigo avalia a legislação que orbita em torno do licenciamento ambiental desses empreendimentos e seus potenciais efeitos negativos Ã garantia da vida e dos direitos dos povos indígenas, e a importância de harmonização com outras normas garantidoras de direitos desses povos.
