Formation and development of the agricultural machinery market in Ukraine
Authors: Adamchuk V. V. , Gritsyshyn M. I. , Perepelytsya N. M. 
Published: March 2021

Annotation
Purpose. To reveal the shortcomings of the formation of the market of agricultural machinery and their impact on the economy of Ukraine.
Methods. Monographic, analytical, economic-mathematical, statistical.
Results. It is established that the introduction of “free prices” in Ukraine led to a violation of the principle of equivalence of exchange between industrial and agricultural products, became the main reason for the loss of effective demand of agricultural enterprises for material and technical resources, the decline of domestic engineering and, as a result, led to the monopolization of the agricultural machinery market foreign firms.
The main reason for the dominance of imported agricultural machinery in the domestic market of Ukraine was the low level of competitiveness of domestic counterparts, the lack of state regulatory policy and experience in the market environment.
The main actions of the bodies of state management of economic development of Ukraine, the implementation of which will contribute to the revival and development of domestic engineering for agriculture and strengthening its position in the domestic market of agricultural machinery.
Conclusions. The lack of state regulation of the domestic market of agricultural machinery has led to the loss of domestic engineering for Ukraine’s agro-industrial complex, the dependence of the agricultural sector of Ukraine’s economy on foreign firms, job losses in industry and reduced revenues to the state budget and social funds.
To revive the industry and increase sales of agricultural machinery of domestic production in domestic and foreign markets it is necessary:
•	to provide favorable conditions for the creation of joint ventures with leading foreign companies for the production in Ukraine of competitive agricultural machinery with a gradual increase in its design share of components of domestic production;
•	to provide state support to the priority areas of development of domestic mechanical engineering for the agro-industrial complex;
•	to provide preferences for equipment of domestic production in the domestic market and to stimulate its export.

Authors: Kalinichenko R. A. R. A. , Stepanenko S. P. , Kotov B. І. 
Published: March 2021

Purpose. Clarification of the mathematical description and calculation of the processes of micronization and vibrational movement of grain in cross-air flow on the basis of experimental studies.
Methods. Experimental studies were performed on a manufactured sample of a machine for high-intensity heat treatment of grain using experimental planning methods and statistical processing of experimental data.
Results. A mathematical description of the motion of grain mixture particles on a vibroconveyor with high-intensity heat treatment of grain during action on the mixture of air flow is given. The trajectories of particles with different sizes depending on high-intensity heat treatment are obtained. With certain assumptions, the regularities of the change in the speed of movement and exposure of the micronization of the material particle (grain) from the coordinates and humidity are obtained.
Conclusions. As a result of research:
1)	a regression dependence was obtained to determine the micronization exposure and it was established that the micronization exposure for the given energy parameters of the installation should last from 60 to 180 seconds;
2)	the change of the speed of vibratory movement of grain depending on its humidity is theoretically substantiated and it is proved that the ascending air flow increases the speed of grain movement, and the descending one – decreases;
3)	experimentally determined the empirical dependence of changes in the speed of vibration, which allows the formation of the required speed of vibration of grain by changing the parameters: the slope of the vibrating surface 5÷8°, oscillation frequency 33÷52 s-1, grain moisture 10÷20% and downward air flow rate 0.1÷2 m / s in rational modes of installation for grain micronization on a vibrating conveyor.
Keywords: trajectory, vibration displacement, vibration conveyor, air flow, micronization, humidity, coefficient of friction.

Some Instances of Homomesy Among Ideals of Posets
Authors: Haddadan Shahrzad 
Published: March 2021

Given a permutation $\tau$ defined on a set of combinatorial objects $S$, together with some statistic $f:S\rightarrow \mathbb{R}$, we say that the triple $\langle S, \tau,f \rangle$ exhibits homomesy if $f$ has the same average along all orbits of $\tau$ in $S$. This phenomenon was observed by Panyushev (2007) and later studied, named and extended by Propp and Roby (2013). Propp and Roby studied homomesy in the set of order ideals in the product of two chains, with two well known permutations, rowmotion and promotion, the statistic being the size of the order ideal. In this paper we extend their results to generalized rowmotion and promotion, together with a wider class of statistics in the product of two chains. Moreover, we derive similar results in other simply described posets. We believe that the framework we set up here can be fruitful in demonstrating homomesy results in order ideals of broader classes of posets.
On Self-Mullineux and Self-Conjugate Partitions
Authors: Bernal Ana 
Published: March 2021

The Mullineux involution is a relevant map that appears in the study of the modular representations of the symmetric group and the alternating group. The fixed points of this map are certain partitions of particular interest. It is known that the cardinality of the set of these self-Mullineux partitions is equal to the cardinality of a distinguished subset of self-conjugate partitions. In this work, we give an explicit bijection between the two families of partitions in terms of the Mullineux symbol.
Skeleton Ideals of Certain Graphs, Standard Monomials and Spherical Parking Functions
Authors: Chanchal Kumar  , Gargi Lather  , Sonica  
Published: March 2021

Let $G$ be a graph on the vertex set $V = \{ 0, 1,\ldots,n\}$ with root $0$. Postnikov and Shapiro were the first to consider a monomial ideal $\mathcal{M}_G$, called the $G$-parking function ideal, in the polynomial ring $ R = {\mathbb{K}}[x_1,\ldots,x_n]$ over a field $\mathbb{K}$ and explained its connection to the chip-firing game on graphs. The standard monomials of the Artinian quotient $\frac{R}{\mathcal{M}_G}$ correspond bijectively to $G$-parking functions. Dochtermann introduced and studied skeleton ideals of the graph $G$, which are subideals of the $G$-parking function ideal with an additional parameter $k ~(0\le k \le n-1)$. A $k$-skeleton ideal $\mathcal{M}_G^{(k)}$ of the graph $G$ is generated by monomials corresponding to non-empty subsets of the set of non-root vertices $[n]$ of size at most $k+1$. Dochtermann obtained many interesting homological and combinatorial properties of these skeleton ideals. In this paper, we study the $k$-skeleton ideals of graphs and for certain classes of graphs provide explicit formulas and combinatorial interpretation of standard monomials and the Betti numbers.
Laparoscopic Cholecystectomy under Segmental Thoracic Spinal Anesthesia
Authors: Aidyl Fitrisyah  , Rizal Zainal  , Edi Darwis 
Published: March 2021

Introduction: Cholelithiasis or gallstones are hardened deposits of digestive fluid that can form in gallbladder. The treatment of gallstones depends upon the stage of disease. Once gallstones become symptomatic, definitive surgical intervention with cholecystectomy is usually indicated (typically, laparoscopic cholecystectomy is the first-line therapy). Laparoscopic cholecystectomy removes the gallbladder and gallstones through several small incisions in the abdomen. This case report aims to discuss the managent of segmental thoracic spinal anesthesia in laparoscopic cholecystectomy.
Case: We report on the cases of 2 patients who undego elective laparoscopic cholecystectomy. Female, 53 years old, will undergo laparoscopic cholecystectomy, performed anesthesia with segmental thoracic spinal anesthesia technique using the anesthetic agent 3 ml of Levobupivacaine 0,5% + 25 mcg of Fentanyl, requiring a sensory block to at least T10-T11 dermatom. Patients received a 1,2 mcg target control infusion (TCI) propofol intravenous is administered as intermittent boluses to achieve deep sedation. The operation lasts 1 hour, with a bleeding 15 cc and urine output 100 cc, hemodynamically stable. Female, 42 years old, will undergo laparoscopic cholecystectomy, performed anesthesia with segmental thoracic spinal anesthesia technique using the anesthetic agent 3 ml of Levobupivacaine 0,5% + 25 mcg of Fentanyl, requiring a sensory block to at least T10-T11 dermatom. Patients received a 3 mg of midazolam intravenous is administered as intermittent boluses to achieve deep sedation. The operation lasts 1 hour, with a bleeding 15 cc and urine output 150 cc, hemodynamically stable. The level and duration of sensory block, intensity and duration of motor block were recorded. A 20 % or more decrease in MAP compared to baseline was considered as hypotension, iv ephedrine 5 mgr bolus administreted.
Conclusion: Laparoscopy is a surgical procedure that uses minimally invasive surgical techniques (minimally invasive surgery) where the doctor uses a small telescope / camera that is inserted into the stomach and surgical instruments in mini form. This procedure has many advantages because it is not invasive, the amount of bleeding can be reduced, postoperative pain can be minimized. Regional anesthesia procedure in laparoscopic cholecystectomy based on several studies and case reports can be performed and is a safe procedure.

The processes of adaptation and transformation of the Altai traditional ethics in the modern sociocultural environment
Authors: Садалова Т.М. 
Published: March 2021

Статья посвящена проблеме выявления основ традиционной этики алтайцев сквозь призму рассмотрения системы традиционной культуры, которая формировалась с древнейших времен. В традиционном обществе этика являлась непосредственной реализацией моральных ценностей. Учитывая, что каждый исторический этап развития народа вносит новации в традиционную культуру и этику как положительного, так и отрицательного характера, эти новации проходят периоды адаптации, что в целом нарушает, трансформирует и деформирует целостность традиционной этики. Автор фокусируется на жизнеспособности традиционной этике в новых условиях.
The article is devoted to the problem of identifying the foundations of the Altaians traditional ethics by considering the system of traditional culture, which has been formed since ancient times. In traditional society, ethics was the direct realization of moral values. Considering that each historical stage of people’s development introduces both positive and negative innovations in traditional culture and ethics, these innovations undergo periods of adaptation, which generally violates, transforms and deforms the integrity of traditional ethics. The author focuses on the viability of traditional ethics in the new conditions.

Identifying Radio-active Galactic Nuclei among Radio-emitting Galaxies

Abstract
Basing our analysis on ROGUE I, a catalog of over 32,000 radio sources associated with optical galaxies, we provide two diagnostics to select the galaxies where the radio emission is dominated by an active galactic nucleus (AGN), referred to in the paper as radio-AGNs. Each of these diagnostics can be applied independently. The first one, dubbed MIRAD, compares the flux F

W3 in the W3 mid-infrared band of the Wide-field Infrared Survey Explorer telescope, with the radio flux at 1.4 GHz, F
1.4. MIRAD requires no optical spectra. The second diagnostic, dubbed DLM, compares the 4000 Å break strength, D
n(4000), with the radio luminosity per unit stellar mass. The DLM diagram has already been used in the past, but not as stand-alone. For these two diagrams, we propose simple, empirical dividing lines that result in the same classification for the objects in common. These lines correctly classify as radio-AGN 99.5% of the extended radio sources in the ROGUE I catalog, and as star-forming galaxies 98%–99% of the galaxies identified as such by their emission-line ratios. Both diagrams clearly show that radio-AGNs are preferentially found among elliptical galaxies and among galaxies hosting the most massive black holes. Most of the radio sources classified as radio-AGNs in the MIRAD or DLM diagrams are either optically weak AGNs or retired galaxies.
