Authors: Dymchuk A. , Ponko L.
Published: November 2022

The article examines the influence of live weight, age of first insemination and calving on the milk productivity of cows of the Ukrainian red-spotted dairy breed in the conditions of LLC "ATZT Myrne" of the Kitsman district of the Chernivtsi region.

The milk productivity of first-born cows largely depends on their live weight, because it is an indicator of the general development and fattening of animals. The results of our research indicate the influence of live weight of animals on their milk productivity. When the live weight of animals at the first insemination increases from 300 to 450 kg, the yield increases by 699.3 kg, milk fat by 28.9 kg, and milk protein by 25.2 kg (P<0.05, P<0.01). The influence of live weight at the first insemination on fertility, the amount of milk fat and protein was 15.1-19.1 %.

When studying the dependence of the milk productivity of first-borns of the Ukrainian red-spotted dairy breed on the age of their first insemination, it was established that the cows with the age of first insemination ranged from 16.1 to 18.0 months had the highest fertility, the amount of milk fat and protein. – 6875.8, 266.6, 227.1 kg, respectively (P<0.05). The influence of the age of first insemination on fertility, the amount of milk fat and protein was 5.7-9.5 %.

According to the results of own research, it was established that the live weight of first-born cows at the first calving affects their milk productivity. With an increase in live weight to 550 kg, their weight increases by 312.9 kg, milk fat by 11 kg, and protein by 10.8 kg. With an increase in live weight of more than 551 kg, the productivity of cows does not increase, but remains at a high level - 6682.7 kg, 257.1 and 220.1 kg, respectively. Correlation coefficients between live weight at the first calving of cows and their productive indicators were -0.072-0.113. A significant influence of the live weight of the firstborns at the first calving on their fertility, the amount of milk fat and protein (15.3-22.9 %) was established, which proves the need for intensive breeding of repair young.

It has been established that the age of first calving of first-born cows affects their future milk productivity. Cows with the age of first calving in the range of 25.1-27.0 months had the highest hope, amount of milk fat and protein. – 6510.2, 252.3 and 217.0 kg, respectively (P<0.05). First-borns with the age of first calving of 29.1–31.0 months were characterized by the lowest indicators of milk productivity. Their weight was 6017.2 kg, the amount of milk fat and protein was 234.7 and 198.6 kg, respectively (P<0.05). The correlation coefficients between the age of the animals at the first calving and their milk productivity were in the range of -0.088–0.240. The influence of the age of the first calving on fertility, the amount of milk fat and protein was 20.7-23.6 %.

Published: November 2022

The key role of establishing and observing ecological and
technological restrictions in the use of arable land for ensuring rational agricultural
land use and preserving the land-resource potential of rural areas is proven.
Methodical approaches to determining ecological and technological limitations in
the use of agricultural land are analyzed. Fragments of the classifier of types of
functional purpose of territories and types of functional purpose of territories and
their correlation with types of purposeful purpose of land plots are given.
The main characteristics of each level of ecological and technological
restrictions related to soil cultivation and sowing of agricultural crops are
highlighted. The need to establish ecological and technological restrictions on the
use of land at the legislative level by introducing a corresponding addition to Article
111 of the Land Code of Ukraine and the possibility of their practical implementation
on the basis of the classifier of types of functional purpose of territories developed by
the authors was substantiated. It is emphasized the need to introduce changes and additions to Appendix 6 of
the current State Land Cadastre Management Procedure regarding the
implementation of ecological and technological restrictions in the use of land, which
should be based on a 4-level classification in which certain ecological and
technological restrictions are associated with the corresponding type of functional
purpose cultivated agricultural areas.

Authors: Vitiuk Anna
Published: November 2022

The basic principles of the functioning of the leading engineering enterprises have been revealed, which foresee the possibility of producing in-demand products in the future, which are based, on the one hand, on the provision of a complex of services for the design, manufacture and service of engineering products, and on the other hand, on the long-term experience of foreign economic activity, which allows to supply own products to the foreign market. The expediency of using the methodology of the theory of effective competition in researching the competitiveness of engineering enterprises is justified. The main aspects of the formation of competitiveness were considered - the efficiency of production activity, financial position and sales of products, as a result of which the formation of an integral indicator of the competitiveness of the enterprise was formed. It was established that the indicators of high efficiency of production activity were ensured due to the growth of production volumes. Ensuring sufficient values ​​of the indicators of the financial condition was based on the basis of increasing the use of the funds involved, which, by investing in effective work, allowed to increase the financial results in an extensive way. Product sales indicators showed the absence of trends in the growth of profit from sales and net income (revenue) from sales, which indicates the different efficiency of engineering enterprises in separate periods of time, which can also be caused by different types and features of production at enterprises. As a result of the analysis, a set of unstable trends in the activities of the studied enterprises was revealed, which was reflected accordingly in the fluctuations of the integral indicator of the competitiveness of the studied enterprises for the period 2016-2020.

Published: November 2022

The article specifies the main directions of innovative changes in business models and business processes of domestic industrial corporations in order to preserve their ability to enter global chains of consumer value creation during the recovery period. According to modern views on the significance of individual components of intellectual capital in the formation of the competitiveness of business entities, creativity is highlighted in their totality, the author's interpretation of the potential of creativity is proposed, and its place in the management system of the competitiveness of an industrial company is determined. The creativity potential of an economic organization is proposed to be considered as its ability to accumulate the necessary amount of intellectual resources for generating creative (non-standard) ideas sufficient for the formation of an effective business model of economic activity in the current and strategically forecasted business environment, while showing creativity in the development of structural capital and relationship capital. It is argued that the organizational and structural conditions for realizing the creative potential of industrial corporations are radical decentralization of management, which is built on the principles of heterarchical organizational structuring. Based on a comparison of the characteristics of organizational "hierarchy" and "heterarchy", their fundamental differences in management approaches are illustrated. The peculiarities of heterarchy as an effective form of increasing the potential of creativity and forming an environment of active innovative search in the organizational shell of corporate and other integrated structures are highlighted.
DIGITAL TRANSFORMATION OF CYBER SECURITY AT THE MICRO-LEVEL UNDER MARTIAL STATUS
Authors: Kraus Kateryna , Kraus Nataliia , Shtepa Olena
Published: November 2022

The article describes the possible transformational processes of cybersecurity of business entities in martial law. Authors argue that the security criteria of modern digital entrepreneurship include the following mandatory facts: data must always be encrypted during storage and transmission; encryption must take place at the client level; only the client should have access to the encryption keys; actual data should not be transmitted through open mail channels; the company must control the storage of encrypted information and access keys to it.

A number of current external and internal threats to doing business are listed, including network intrusion, loss of devices with saved passwords, and encryption viruses. Main tasks of enterprises in terms of cybersecurity, namely: identification of potential threats to cybersecurity of enterprises and vulnerabilities; cyber incident prevention; neutralization or minimization of threats to information security of the enterprise.

Authors consider the impact of the information security management system ISO / IEC 27001: 2013 on the work of organizations. It has been found that this system provides an opportunity to implement best practices to improve data protection and eliminate the threat of security breaches of information systems.

The article focuses on the fact that in the framework of cybersecurity in martial law and in the further digitization of activities at the micro level, the basic and priority tasks should be mainly new quality of production processes of technological laboratories: planning work in accordance with requirements industry standards, guidelines and best practices; sampling into the system by assigning it a specific identifier; calculation of results and their design.

Entrepreneurial practice shows that, for example, Ramsomware is the most common threat in the implementation of business processes. Ramsomware is divided into two main types – cryptographers (“cryptoransomware”) and blockers (blockers –“blockers”). Encryptors, when they get to the main computer of the enterprise, encrypt valuable files such as documents, photos, databases. Ramsomware’s business threats include, for example, temporary data loss, which can completely disrupt critical business processes; constant data losses, leading to a decline in the company’s competitiveness, reduced sales revenue in the long run, disrupted continuous access to data.

Authors of the article came to the conclusion that in the light of such criminal cyberattacks, of course, it is logical to develop various types of protection in order to protect data from their interception. This protection must be: invisible to the naked eye; have a secure mail channel; e-mail certificate; e-mail safe; e-mail shredder; cybersecurity center; encryption of letters and attachments; protected view.

À chaque étape, nos réflexions sont illustrées par des exemples concrets. Cet article met en exergue la nécessité de la réflexion à la fois clinique et éthique dans le domaine de la recherche en psycho-oncologie.
The Poetry of Snails
Authors: Fraser Benjamin
Published: November 2022

The graphic novel Duelo de caracoles [Duel of snails] (2010) by Sonia Pulido (images) and Pere Joan (script) recounts a meal of snails shared by friends, a simple premise upon which Pulido overlays complex layouts that elevate the snail to the conceptual level of metaphor, symbol and allegory. A brief analysis of Estudios psicológicos [Psychological studies], a single-page comic featuring snails by Apel·les Mestres i Oñós, outlines basic principles of layout and the representation of subjectivity/interiority that inform subsequent discussion. Pulido and Pere Joan’s comic privileges Thierry Groensteen’s categories of the shown, the intervened and the signified. Pulido’s poetic mode of composition captures the polyphony of group dynamics, occasioning multiple interpretations of the page within and beyond the inter-iconic space.
Ridiculous Empire
Authors: Aman Robert
Published: November 2022

This article analyses the works of Olivier Schrauwen with a particular focus on his comic Arsène Schrauwen, which plays out in the colonial context of the Congo. It argues that Schrauwen’s comics exploit the formal qualities of the colonial adventure genre that is frequent in traditional European comics as a way of subverting and satirising them. It further argues that through a constant reliance on meta-references to other works and tropes recognisable from adventure tales, in combination with the adoption of a strict colonialist world view, Schrauwen humorously ridicules the asymmetrical binaries between coloniser and colonised.

Authors: Rahayu Eka Suci , Ma'arif Alfian , Çakan Abdullah
Published: November 2022

The use of DC motors is now common because of its advantages and has become an important necessity in helping human activities. Generally, motor control is designed with PID control. The main problem that is often discussed in PID is parameter tuning, namely determining the value of the Kp, Ki, and Kd parameters in order to obtain optimal system performance. In this study, one method for tuning PID parameters on a DC motor will be used, namely the Particle Swarm Optimization (PSO) method. Parameter optimization using the PSO method has stable results compared to other methods. The results of tuning the PID controller parameters using the PSO method on the MATLAB Simulink obtained optimal results where the value of Kp = 8.9099, K = 2.1469, and Kd = 0.31952 with the value of rise time of 0.0740, settling time of 0.1361 and overshoot of 0. Then the results of hardware testing by entering the PID value in the Arduino IDE software produce a stable motor speed response where Kp = 1.4551, Ki= 1.3079, and Kd = 0.80271 with a rise time value of 4.3296, settling time of 7.3333 and overshoot of 1.

Authors: Adeola-Bello Zulikha Ayomikun , Azlan Norsinnira Zainul
Published: November 2022

This article attempts to review papers on power assist rehabilitation robots, human motion intention, control laws, and estimation of power assist rehabilitation robots based on human motion intention in recent years. This paper presents the various ways in which human motion intention in rehabilitation can be estimated. This paper also elaborates on the control laws for the estimation of motion intention of the power assist rehabilitation robot. From the review, it has been found that the motion intention estimation method includes: Artificial Intelligence-based motion intention and Model-based motion intention estimation. The controllers include hybrid force/position control, EMG control, and adaptive control. Furthermore, Artificial Intelligence based motion intention estimation can be subdivided into Electromyography (EMG), Surface Electromyography (SEMG), Extreme Learning Machine (ELM), and Electromyography-based Admittance Control (EAC). Also, Model-based motion intention estimation can be subdivided into Impedance and Admittance control interaction. Having reviewed several papers, EAC and ELM are proposed for efficient motion intention estimation under artificial-based motion intention. In future works, Impedance and Admittance control methods are suggested under model-based motion intention for efficient estimation of motion intention of power assist rehabilitation robot.  In addition, hybrid force/position control and adaptive control are suggested for the selection of control laws. The findings of this review paper can be used for developing an efficient power assist rehabilitation robot with motion intention to aid people with lower or upper limb impairment.

Authors: Maaruf Muhammad , Mahmoud Magdi Sadek , Ma'arif Alfian
Published: November 2022

Flight control design of unmanned aerial vehicles UAVs is becoming increasingly important due to advances in computational power of computers with lower cost. The control algorithms are mainly employed for the attitude and position control of the UAVs. In the past decades, quadrotors have become the most popular UAVs, their adaptability and small size. They are employed to carry out tasks such as delivery, exploration,  fumigation, mapping, surveillance, rescue mission, traffic monitoring, and so on. While carrying out these tasks, quadrotor UAVs face various challenges, such as environmental disturbances, obstacles, and parametric and non-parametric perturbations. Therefore, they require robust and effective control to stabilize them and enhance their performance. This paper provides a survey of recent developments in control algorithms applied to attitude and position loops of quadrotor UAVs. In addition, the limitations of the previous control approaches are presented. In order to overcome the relative drawbacks of the previous control techniques and enhance the performance of the quadrotor, researchers are combining various control approaches to obtain the hybrid control architecture. In this study, a review of the recent hybrid control schemes is presented.
Design of Hybrid Controller using Qualitative Simulation Internal Modeling for Inverted Pendulum
Authors: Xia Chunrong , Qaisar Irfan , Aslam Muhammad Shamrooz
Published: November 2022

Multiple model methods for nonlinear dynamical system control are appealing because local models can be simple and obvious, and global dynamics can be studied in terms of transitions between small operating zones. In this study, we propose that using qualitative models strengthens the multiple model method even more by enabling each local model to explain a huge class of effective nonlinear dynamical systems. Furthermore, reasoning using qualitative models reveals weak necessary conditions sufficient to verify qualitative features like stability analysis. The authors show the method by creating a global controller for the free pendulum. In addition, local controllers are specified and validated by comparing their patterns to basic general qualitative models. Our proposed procedure establishes qualitative limitations on controller designs that are sufficient to ensure the necessary local attributes and to establish feasible transitions between local areas for the existing problems. As a result, the continuous phase picture may be reduced to a simple transitional graph. The degrees of freedom in the system that are not bound by the qualitative description are still accessible to the designer for optimization for any other purpose. An example of a pendulum plant illustrates the effectiveness of the proposed method.

Published: November 2022

Drug searches are still based on drug names and brands, making it difficult for patients to come looking for a cure by saying that they feel sick. Likewise, when looking for drugs and information about their content to avoid overdose errors when changing drugs when drugs are supposed to be unavailable. Based on the issues raised, a study was conducted on applying semantic web ontology to search for drugs that can appear based on patients’ names, compositions, or complaints of diseases. Protégé 5.5 serves to represent drug information based on knowledge. The application uses Netbeans with Jena API as a library and creates data and drug information on the semantic web. Drug search also uses similar in-formation meaning based on user knowledge. By representing knowledge on the search for drug and disease information with semantic web ontology technology, it can meet the purpose of research, namely to improve drug and disease information search following the user’s wishes.

Published: November 2022

Cikeruh-Citarik sub-watershed is a part of the upstream zone of the Citarum watershed which is classified as a watershed with critical conditions in West Java. The change in land use as a side effect of the increasing population causes a degradation of the watershed. Land-use change in a watershed without considering any conservation rules leads to erosion, becoming a watershed criticality indicator. Erosion can be minimized by using a prediction model to predict the amount of erosion that might happen, for the result could help to decide which conservation action is needed in the watershed rehabilitation. GeoWEPP is one of the prediction models that is suitable for predicting the amount of erosion on a watershed scale.

La pandemia originada por coronavirus (COVID-19) ocasionada por el coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2), además de ocasionar una problemática de salud pública global ha afectado los hábitos y calidad de vida de los individuos debido al confinamiento por riesgo de contagio. En este escenario, la Diabetes Mellitus Tipo 2 (DM2) considerada una de las comorbilidades más frecuentes en personas con COVID-19 desencadenó una mayor tasa de ingreso hospitalario y mortalidad. Asimismo, la obesidad se ha vinculado con mayor riesgo de complicaciones y mortalidad en pacientes con diagnóstico de COVID-19. Los mecanismos que intentan explicar la asociación entre la COVID-19, DM2 y obesidad no se encuentran esclarecidos en su totalidad. Sin embargo, se ha identificado a la inflamación crónica como un elemento central en este contexto. En efecto, la obesidad ha incrementado su prevalencia a edades tempranas lo que implica la aparición de complicaciones como resistencia a la insulina y DM2, patologías que elevan el riesgo de infecciones y complicaciones por SARS-CoV-2. En este artículo se explora la relación entre la obesidad y DM2 en el contexto de la COVID-19 y sus repercusiones.

Iron ore beneficiation technologies in Russia and ways to improve their efficiency
Authors: Pelevin Aleksey
Published: November 2022

Increasing the efficiency of crushing circuits is associated with a decrease in the particle size of finely crushed ore and the use of dry magnetic separation of crushed ore. Reducing grinding costs is achieved by using drum mills jointly with mills of other designs. The use of automation systems, slurry demagnetization, technologies with staged concentrate separation, and beneficiation and fine screening in a closed grinding cycle lead to a reduction in grinding costs. The main industrial technology for improving the quality of concentrate is its additional beneficiation using regrinding, fine screening, flotation, and magnetic-gravity separators. Increasing the integrated use of iron ore raw materials is associated with an increase in the yield of iron concentrate and the production of hematite concentrate during the beneficiation of hematite-magnetite ores and ilmenite concentrate during the beneficiation of titanomagnetite ores. Incremented concentrate yield is possible by using magnetic separators with an increased magnetic induction up to 0.25-0.5 T in the first stages of beneficiation. To obtain hematite and ilmenite concentrates, combined technologies can be used, including fine screening, high-gradient magnetic, gravity, flotation, and electrical separation.

One of the most reliable methods for assessing the physical and mechanical properties of rocks as a result of their destruction are laboratory tests using hard or servo-driven test presses. They allow to obtain reliable information about changes in these properties beyond the limit of compressive strength. The results of laboratory tests of rich sulfide ore samples are presented, which made it possible to obtain graphs of their extreme deformation. Both monolithic samples and samples with stress concentrators in the form of circular holes with a diameter of 3, 5 and 10 mm were tested. It was revealed that during the destruction of the samples, the modules of elasticity and deformation decrease by 1.5-2 times, and in the zone of residual strength – by 5-7 times.

Grinding is the most energy-intensive process among all stages of raw material preparation and determines the course of subsequent ore beneficiation stages. Level of electricity consumption is determined in accordance with load characteristics forming as a result of ore destruction in the mill. Mill drum speed is one of process variables due to which it is possible to control ore destruction mechanisms when choosing speed operation mode of adjustable electric mill drive. This study on increasing energy efficiency due to using mill electric drive is based on integrated modelling of process equipment – grinding process and electromechanic equipment – electric drive of grinding process. Evaluating load torque by means of its decomposition into a spectrum, mill condition is identified by changing signs of frequency components of torque spectrum; and when studying electromagnetic torque of electric drive, grinding process is monitored. Evaluation and selection of efficient operation mode of electric drive is based on the obtained spectrum of electromagnetic torque. Research results showed that with increasing mill drum speed – increasing impact energy, load torque values are comparable for the assigned simulation parameters. From the spectra obtained, it is possible to identify mill load condition – speed and fill level. This approach allows evaluating the impact of changes in process variables of grinding process on parameters of electromechanical system. Changing speed operation mode will increase grinding productivity by reducing the time of ore grinding and will not lead to growth of energy consumption. Integration of digital models of the technological process and automated electric drive system allows forming the basis for developing integrated methods of monitoring and evaluation of energy efficiency of the entire technological chain of ore beneficiation.

Este trabalho tem por objeto de investigação os fatores jurídicos e técnicos relacionados a viabilidade de obtenção de patentes de invenções implementadas por programas de computador. O estudo integra o campo dos direitos de propriedade intelectual, em especial aqueles relativos à incidência da Lei nº 9.279/1996. Realizado a partir de revisão bibliográfica e análise documental, os resultados apontam que os programas de computador se tornaram objeto de interesse mercantil autônomo a partir da década de 70, e que, ao longo das últimas décadas, houve um significativo incremento econômico do setor. Os estudos indicam também que o programa de computador “em si”, compreende um conjunto de instruções que possibilitam o funcionamento de computadores e de tratamento de dados que propiciam a gestão da informação das organizações em determinados contextos. Nesta qualidade, os programas não são invenções, para efeito do que dispõe o regime de propriedade industrial, mas podem ser considerados uma espécie de “matéria prima” a partir da qual uma invenção pode ser implementada, assim como se observa na relação entre as instruções (equiparadas por lei à obras literárias), as quais são implementadas por linguagens.
Refugiados e a vida nua

O presente artigo almeja apresentar a postura de acolhimento dos refugiados ucranianos, pelos demais países componentes da Europa, como comprovação empírica de que os valores do campo do direito internacional e das relações internacionais, permanecem, mesmo frente a toda evolução em sua sistemática, permeados, em seu âmago, de uma visão limitada de quem é o factual “sujeito de direitos”, dentro da categoria de refugiados. Diante disso, demarcando quem são os refugiados em cerne, ou seja, os que figuram alvos da limitação de direitos e xenofobia, vítimas em um cenário cujas próprias instituições de auxílio e proteção são inoperantes, no que tange a uma ajuda efetiva.
