The productive traits of cattle are controlled by a large number of genes. There is a association between certain genetic markers and productive traits of animals, and in the process of breeding a change in the allelofund of herds aff ects the productive traits of animals. The purpose of the research was to make genotyping of cattle of Holstein breed to LEP gene and analyze its association with the milk productivity of fi rst-calf heifers. Studies of milk productivity in the context of the polymorphism of LEP gene demonstrate the superiority of animals with TT genotype in terms of milk yield, fat mass fraction in milk, milk fat yield, milk protein and total milk fat and protein yield. The fi rst-calf heifers carrying the homozygous allele C differed favorably in the content of the mass fraction of protein. The fi rst-calf heifers with the homozygous TT genotype had high milk productivity and had a high milk coeffi cient. Depending on the genotype the average monthly milk yield and the character of lactation curves changed. Animals with TT genotype has shown high milk yield during the fi rst fi ve months of lactation (from 2 to 6), the peak occurred in the third month after calving. A similar trend in this indicator was observed in the fi rst-calf heifers with CC genotype, but they had high milk productivity for four months, the peak of their productivity was noted in the second month of lactation. Lower indicators for the herd were found in animals with the heterozygous TC genotype. Having a stable and smooth, without jumps, lactation curve their results were minimal for the studied livestock, with a fixed maximum average monthly milk yield in the fourth month of lactation.

Increasing the productivity and effi ciency of lamb production is a key factor in the competitiveness of the meat sheep industry. Therefore, in order to conduct sheep breeding more effectively it is necessary to apply new approaches to increase and improve the quality of products.Considerable interest are modern technologies involving the use of DNA markers, which are widely used in national breeding programs of a number of countries with developed animal husbandry and have a signifi cant impact on improving productivity indicators. A significant number of genes associated with meat productivity and meat quality have been identifi ed. However, in sheep breeding, information about the main genes or loci that affect the growth characteristics and productive traits of sheep is relatively limited. Due to the growing interest in the production of young mutton and lamb, priority is given to the study of genes that control meat productivity. The greatest interests are studies on the evaluation of the polymorphism of the growth hormone (GH) gene, which controls growth and development, as well as infl uencing the meat productivity of sheep. In this regard, the purpose of this work was research aimed at fi nding associations between polymorphic variants of the growth hormone gene and the qualitative characteristics of meat in meat and wool sheep of the genotype ½ Poll Dorset × ½ North Caucasian Meat and Wool breed bred in the Stavropol Territory. The data obtained when studying the histostructure of the m. Longissimus dorsi, depending on the genotypes of GH gene, indicate that the muscle tissue in individuals with AB and BB genotypes was characterized by a large number of muscle fi bers by 5,7 and 6,4 %, their smaller diameter by 7,6 and 9,2 %, and a lower content of connective tissue compared to animals with the genotype AA of GH gene.

The study of the accumulation and spatial distribution of ecotoxicants on agricultural lands is one of the important aspects in solving the problem related to the environmental safety of animal feed and food products obtained. In this regard, there is a need to assess the content of pollutants in the chain atmosphere – snow cover. The purpose of the research was to assess the level of contamination of the snow cover of agricultural enterprises in the areas of the north-west of the Kurgan region exposed to man-made impacts. In the north-western part of the Kurgan region three variants of territories were identifi ed that diff er in the degree of environmental stress. The fi rst territory is experiencing the load from the nearby powerful South Ural industrial agglomeration, subject to transboundary man–made pollution, spreading both by water and aerogenically (Kataysky area); the second territory is the subject to transboundary man-made pollution by enterprises of the Chelyabinsk region, and is the location of facilities for the storage and destruction of chemical weapons (Shchuchansky area); the third territory is the territory of relative ecological well–being (Shadrinsky and Kargapolsky areas). In the areas of the north-west of the Kurgan region, the zonal nature of technogenic pollution of snow cover and soils has been revealed. Pollution of the studied territories occurs through the introduction of technogenic aerosols, as well as the influence of local sources. It was revealed that nitrites, nitrates, ammonium nitrogen, manganese make up the largest share in the association of pollution of the studied territories, while sulfates, chlorides and zinc make up the smallest share. In the snow cover, the highest concentration of heavy metals was detected in the fi rst and second territories. The third territory is subject to contamination by the studied elements to a lesser extent.

Considering that these diseases will also concern public health, new research is required. Hirstiellosis is a zoonotic ectoparasitic disease seen in green iguanas (Iguana iguana). Recommended therapies are mostly empirical, some of which can be low-impact or toxic. The objective of this study is to determine the effectiveness of ivermectin solution (5 mg/l) in the treatment of hirstiellosis and to provide preliminary data for further studies. Ivermectin solution was found to be effective in the treatment of three iguanas with the aforementioned disease, and no clinical side effects were found in the control examinations made at regular intervals.
CURRENT PROBLEMS OF LEGAL REGULATION OF THE STATUS OF A SPECIALIST IN THE CONTEXT OF INTRODUCING CHANGES TO THE CRIMINAL PROCEDURAL LAW
Authors: Kukhareva Svitlana , Kalnoi Dmytro , Kaminskyi Anton
Published: August 2022

The article deals with the latest changes in the Criminal Procedure Code of Ukraine regarding the powers of a specialist as a participant in criminal proceedings.

The issue of involving a specialist in criminal proceedings when copying information and taking readings of technical devices and technical means that have the functions of a photo, filming, video recording or means photo, filming, video recording has been studied.

According to the Criminal Procedure Code of Ukraine, a specialist is one of the other participants in criminal proceedings and assists the parties, the victim, the court in the implementation of the tasks of criminal proceedings through the use of his special knowledge and skills in the use of technical or other means, as well as by providing them with advice, explanations, references and conclusions during the pretrial investigation and trial on issues, the clarification and solution of which require special knowledge and skills.

The investigation of mass cyber-attacks on web resources, databases of state authorities and local governments, etc., especially those committed in wartime, requires an appropriate response, in particular, legal regulation of the interaction of specialists with other participants in the criminal process to help increase the effectiveness of such investigation.

The involvement of a specialist in accordance with the Criminal Procedure Code of Ukraine is mandatory both in the case of copying information from a computer system for the owner of the property (if the corresponding computer system is temporarily withdrawn) and in the case of copying information for the investigator or prosecutor (if the corresponding computer or other system remains with its owner).

It is concluded that it is expedient to change the wording of the relevant requirements of the legislation, leaving the investigator or the prosecutor the right to determine the need to involve a specialist or the possibility of carrying out the specified copying without his participation.

It is advisable to amend the legislation in order to secure the requirement for mandatory motivation by the court of refusal to take into account the explanations, and consultations provided by a specialist involved in the defense.

It also seems necessary to determine the basic requirements for the content of a specialist's certificate (for example, the name of the criminal proceedings and its registration number; information about the relevant means present during the taking of testimony, and the period of time for which such testimony was taken).

Key words: specialist, reference, explanation, copying of information, photography, video recording, testimony, pre-trial investigation, investigator.

Published: August 2022

The article is devoted to the issues of defining the concept of artificial intelligence, fixing this concept in national legislation and its application in the text of legal acts regulating the organization and implementation of legal proceedings in Ukraine.

The authors point out the problems associated with the use of the concept of artificial
intelligence in the legal proceedings of Ukraine and make proposals for solving these
problems.

In the article, the authors note that in our time, the prevalence of the use of
artificial intelligence in various areas of human life, ideas for its implementation in
legal proceedings have become more often expressed by scientists. They cite as an
example the Chinese experience of the functioning of the digital court.

The definitions of the concept of “artificial intelligence”, which are available in
explanatory dictionaries and encyclopedias, are analyzed. Attention is drawn to the
need to reflect in the definition of this concept not only the technical component of
devices that imitate human activity, but such human abilities as to calculate, reveal
the meaning, generalize and learn from past experience.

It is pointed out the need to take into account in the definition of the concept and
when using artificial intelligence the special standards of reliability of artificial intelligence set out in the technical report ISO/IEC TR 24028 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), as well as the European Ethical Charter CEPEJ on the use artificial intelligence in judicial systems, which defines the main methodological principles used in the automated processing of judicial decisions.

In national legal proceedings, specialized software is reduced to the use of an automated court document management system. It is concluded that at the moment in Ukraine there is no regulatory framework for the use of artificial intelligence in order to make judicial decisions.

Key words: legal proceedings; artificial intelligence; digital court; specialized

Durable dropwise condensation of saturated vapor is of significance for heat transfer and energy saving in extensive industrial applications. While numerous superhydrophobic surfaces can promote steam condensation, maintaining discrete microdroplets on surfaces without the formation of a flooded filmwise condensation at high subcooling remains challenging. Here, we report the development of carbon nanotube array-embedded hierarchical composite surfaces that enable ultra-durable dropwise condensation under a wide range of subcooling (

Authors: Kuropiatnyk O.
Published: August 2022

There are many software solutions for detecting text borrowings. In their development, special attention is paid to methods and algorithms for detecting borrowings, the characteristics of their work. However, technology and usability issues that are directly related to the user interface (UI) are also important. UI design consists of many stages, including the development of a dialogue scenario. The development and testing of a dialogue scenario avoids the difficulty of choosing operations, the state of the program without exit and the lack of necessary data in the already completed transi-tion to an operation. The dialogue scenario can be presented in verbal or formalized form: dialogue graph, automata, Petri nets, UML diagrams of precedents, activities and states. The aim of this paper is to interpret the components of the Petri net to model dialogue scenarios. The tasks are: to determine the essence and purpose of the components of the color Petri net in terms of the components of the dialogue scenario and the process of the program work; construction of a scenario model of dialogue and implementation user interface for the text borrowings detection system of on its basis. To model the scenario, a general coloured Petri net is defined. Its set of positions corre-sponds to the states of the program and is characterized by the set of values of input and output parameters and actions for their transformation. The set of transitions indicates the set of user actions in a certain state. The set of security conditions on transitions control the availability of data in the program to perform operations in a certain state. The rules of formation of these conditions are determined in the work. Chip types denote different sets of input and output data. This interpretation of the net was used to build a scenario model of the dialogue of the text borrowing detection system. Analysis of network properties showed its adequacy of the model to the object of modeling. The results of the implementation of the user interface according to the developed model are presented. The conclusions form the main advantages of using coloured Petri nets to model a dia-logue scenario.

Published: August 2022

Irrigation machines of the Frigate series are mainly used in closed irrigation systems in the south of Ukraine. During the operation of such systems there are problems with pressure control in the system, the problem of remote control of irrigation. A possible solution to these problems is to control the pressure in the water supply line of sprinklers, by automatically controlling the pumping equipment and installing appropriate sensors (pressure, flow meters, etc.) for feedback to the control system. By controlling the pumping equipment that creates pressure in the mains, it is possible to ensure proper modes of operation in the water supply mains of the DMU. Appropriate software for statistical data collection and management is also needed to improve watering and remote monitoring of the system. The aim of the study is to build a mathematical model of a closed irrigation system as an object of management, which will analyze the processes occurring in the system and evaluate the effectiveness of management methods being developed. The article considers the scheme of relationships between the main components of a closed irrigation system such as pump unit, distribution and irrigation pipeline, shut-off valves, universal sprinklers, control system with further mathematical description of each component. The main parameters of the system that affect its operation are identified. Set quality indicators that are put forward to the control system. The system as an object of control is analyzed, input, output and internal parameters of the system are revealed. The mathematical model of ZSS is built from the considered models of components, gives the chance to analyze the processes proceeding in system, and to estimate efficiency of the management methods developed. To determine the adequacy of the mathematical model, which is created by the proposed approach, it is advisable to simulate the operation of the ZSS for real conditions in different modes of operation. To determine the properties of ZSS as an object of control, such as inertia, controllability, stability, observation, it is necessary to obtain a model of the complex in the space of states.

Published: August 2022

To solve practical problems, including for the management of territories, monitoring of emergencies, for the development of the ecology of our planet, for the study and ecological research of our planet, effective algorithms for the segmentation of multispectral images are needed. In recent years, image segmentation using convolutional neural networks has become very popular. A significant difference of this approach is the annotation of the assignment of each pixel to a particular class of objects, so that the learning process of such networks is completely controlled. The paper proposes a new method for segmentation of aerospace im-ages of high spatial resolution based on convolutional neural networks and mask generation. Our model is based on a combined U-Net network with MobileNetV2 as the backbone. It trains on ground data and provides a full prediction mask. A network has been implemented, consisting of separate networks of the same class, working on the expansion of segmentation. Semantic features are used to reduce errors at the semantic level of the outline. Since an in-dependent test revealed some shortcomings in certain classes of the earth's surface, further re-search will be devoted to the creation of a catalog of training samples to support successful differentiation of objects. In general, the obtained accuracy estimates demonstrate the modern characteristics of the developed model, as well as the effectiveness of this combination of network and datasets for test regions. The results show that the proposed algorithm can effec-tively improve the overall accuracy of the semantic segmentation of high spatial resolution remote sensing images and reduce the training time and segmentation time.

Authors: Kutzova V. , Ivanchenko V. , Kotova T. , Kovzel M.
Published: August 2022

Skin-rolling is the final operation of the technological process for the production of auto sheet steel. Tempering affects the quality of the metal surface, properties and stamping ability. Treading allows you to harden the surface of the rolled products and keep the inner layers undeformed. As a result, it is possible to prevent the formation of shear lines during stamping and provide an optimal combination of the mechanical characteristics of rolled products. On skin-rolling mills, the sheet is rolled to a predetermined thickness. Treading etched sheets provides them with a smoother surface. Benefits skin training are to increase the ability of the material to deep drawing and reduce energy costs during stamping.The use of skin-rolling will allow to produce high-quality rolled products in accordance with the requirements of standards. An analysis of the effect of skin-rolling on the quality indicators of low-carbon steel thin-rolled products for the automotive industry was carried out. The effect of skin-rolling on the structure and mechanical properties of hot-rolled extra-thin sheet metal from 08пс low-carbon steel was studied. The mechanical properties of the metal meet the requirements of ДСТУ 2834-94 for hot-rolled and cold-rolled steel. Annealing of extra-thin sheet steel from 08пс steel increases its plasticity compared to the hot-rolled state and contributes to the formation of a uniform metal structure in accordance with ДСТУ 2834-94. The choice of parameters and optimization of the skin-rolling process will prevent a decrease in the plasticity of the material, improve mechanical properties and improve the quality of extra-thin sheet steel.

All the languages that have appeared in the world are born after which it got better. But the truth is that our Tamil language was born better. Sangam Literature, Classical Literature, includes Patthuppaatu (Ten Idylls) and Etthutthokai (Eight Anthologies). Earth can be said to be fundamental in the reasons for a group's gradual cultural development. In such a case, in Kurunthokai, a part of Ettutthokai, the characteristics that are appropriate to Marutham land, a pretend love quarrel, and the association with the hustlers are found in Marutham thinai songs. This article examines how the Panars, who were considered by the society of that time to be lower class people and ignoble caste, were crushed for having participated greatly in doing their duties. Their cultural structure, which was based on caste, and their economic status were dependent on others forever. As a result, they lived in poverty and supplication. For the sake of material things, they were able to give material things to the Panars, who were the lower class people, to do the work they desired. The Panars were crushed on many levels. They were considered despicable and deserving of ridicule by all for doing lowly jobs and being instrumental in sorting out the issues in the love quarrel between the husband and wife. Despite their eloquence, intelligence, and sophisticated intellect, their society is said to be a casteless society, but this study has tried to explain the fact that the lower castes were secretly humiliated, the tasks given to them, the work they did, and the society that tried to develop by ignoring them.

For hundreds of years, the news values have remained unchanged. There was a particular and unchanged process of transforming the information in the news. The data was gathered by reporters, turned into the news by the editors, and published by the editor in chiefs. The selection criteria appear to be the same, but the distribution has changed with technological developments. This paper tries to identify the changes in the process of gathering information, news selection, and news broadcasting. We will analyze how the roles have changed and how the new news values appear. In addition, it is essential to examine the ranking of the news val-ues influenced by the digital platforms. We will examine the role of new technology in infor-mation gathering and news diffusion. The paper will explain how roles changes affect news values. Based on the theory, we will see how the new technology influences the newsgathering process and how it influences the persons involved.

The presence of predictable cavities inside a structure is often preferable as it will reduce the vibration amplitude. In this article, inspired by the traditional mass attached to the beam system, in order to solve the problem of free vibration of the steel liquid storage tank with a column made of porous and perforated materials using an exact analytical continuum model is formed. The free vibration response of the mass attached column made of porous materials and holes is established by using a new analytical method known as the Fourier series with Stokes’ transform. The free vibration frequencies are obtained by using an eigen-value approximation, and the influences of the number of holes, filling ratio, porosity and other parameters on the free vibration response are explored. It is shown that an increase in the mass parameter, filling ratio and porosity parameter of the column with an attached mass system could significantly affect the free vibration response of the system.

This paper shows the development of a Ruby application to detect the actions carried out on an USB control, with the goal of achieving the coding of multiplatform application that can be used as a basis for the creation of projects with larger scope and impact in this fiel, such as videogame development, and device control systems. The ‘prototype models’ methodology was the approach for this project. In the first prototype a CLI program was written that prints out messages in the terminal depending on the buttons that are simulated based on the keys pressed on the keyboard, and so on until the end of the project, in which a final application is delivered, in compliance with the necessary tests. This application code was published in a GITLAB repository for reference and future use. The application was developed to be compatible with Windows, Linux, macOS, and Raspbian operating systems to test Ruby portability.
Boyun Ağrısına Manyetik Rezonans Görüntüleme Şart Mı?
Authors: SORAN Neslihan , SATIŞ Serap
Published: August 2022

Amaç
Boyun ağrısı olan hastalarda ekonomik olarak maliyeti yüksek olan manyetik rezonans görüntüleme bulgularının klinik ile ilişkisini araştırmayı amaçladık.
Materyal ve Metod
Çalışmaya Ocak-Aralık 2019 tarihlerinde boyun ağrısı şikayeti ile başvuran ve manyetik rezonans görüntüleme yapılan hastalar dahil edildi. Görüntüleme normal olan ve olmayanlar olarak iki gruba ayrıldı ve yaş, cinsiyet ve ağrı skaları karşılaştırıldı. Ayrıca en sık gözlenen tekli ve çoklu bulgular değerlendirildi.
Bulgular
Boyun ağrısı şikayeti olup görüntüleme de normal olan hastaların sayısı 21; patolojik bulgu olanların sayısı 130 idi. Yaş ortalamaları sırasıyla, 37.23±14.96 ile 45.66±13.24 olup aradaki fark gruplar arasında istatistiksel olarak anlamlıydı (p=0,023). Ağrı skalası; 7.09±0.94 ile 7.03±1.20 olarak bulundu, gruplar arasında istatistiksel fark gözlenmedi (p=0,782). Görüntülemesi normal olan grupta 15 kadın 6 erkek; diğer grupta da 99 kadın 31 erkek hasta vardı; cinsiyet açısından gruplar arasında fark gözlenmedi (p=0,411). Tek görüntüleme bulgusu olan hasta sayısı 54 olup; 21 hasta ile en fazla olan görüntüleme bulgusu bulging olup Protrüzyon-Düzleşme 25 (%19.2) birlikteliği en fazla idi.
Sonuç
Boyun ağrısı şikayeti olan hastaların ağrı ve görüntüleme bulguları arasında ilişki gözlenmemesi bu hastalarda ayrıntılı öykü ve fizik bakının, ekonomik maliyeti yüksek olan manyetik rezonans görüntülemeden daha önemli olabileceğini düşündürmektedir.
