Used cooking oil has a high level of free fatty acids (FFA) and peroxide numbers caused by oxidation processes. One of the efforts to lower the levels of free fatty acids and peroxide numbers by adding natural antioxidants from sungkai leaf extract (Perorena Canescens Jack). Sungkai leaf extract contains several secondary metabolite compounds such as alkaloids, flavonoids, phenolics, steroids and saponins which have the potential to be natural antioxidants. This study aims to determine the ability of sungkai leaf extract to reduce the level of free fatty acids and peroxide numbers in used cooking oil and find out the concentration of sungkai leaf extract which is effective in reducing the level of free fatty acids and the number of peroxides in used cooking oil. In this study, sungkai leaf extract was varied in concentration, namely 0.25%, 0.5%, 0.75% 1%, and 1.25% of the mass of used cooking oil used. Used cooking oil is heated using a hotplate for 15 minutes at 80°C and stirred using a magnetic stirrer at a rate of 200 rpm, stored for 3 days and filtered using filter paper. The results showed that sungkai leaf extract can reduce levels of free fatty acids and peroxide numbers in used cooking oil. The best results were obtained at a concentration of sungkai leaf extract of 1.25% w/v with a free fatty acid content of 1.25% and a peroxide number of 10.45 meq O2/kg.

ARCHITECTONICS OF CALCULATED MATHEMATICAL MODELS UNDER UNCERTAINTY
Authors:   State Biotechnological University, LEVKIN Dmytro
Published: February 2023

This article concerns the improvement of calculated mathematical models of technological, biotechnological, and economic systems. It is necessary to increase the number of considered parameters to increase the accuracy of calculating the parameters of complex systems during mathematical modeling. This leads to the need to solve nonlocal boundary value problems with non-stationary differential equations, to prove the correctness of which it is impossible to apply the traditional theory of existence and unity of solution. Note that after the architecture of boundary value problems assumes the existence of their solution, it is only necessary to prove its uniqueness. To prove the correctness of calculated mathematical models requires neither generalizing the parameters of the goal function and using approximate constraints, which, in turn, will reduce the boundary value problem to a standard form and its correctness will not be in doubt, nor propose a method to prove the correctness of boundary value certain differential equations, which will consider the specific features of the modeled processes. A separate technique must substantiate the correctness of boundary value problems depending on the type of differential equation that describes the physical and economic processes in the simulated systems. This article studied the conditions for the correctness of boundary value problems for differential equations with constant coefficients. It is proved that there is a corresponding boundary value problem for arbitrary homogeneous differential equations. It is defined the parabolic boundary value problems in terms that use constraints from above on the fundamental solution function. The conditions were obtained under which the parabolic boundary value problem exists and cannot exist, respectively. The obtained results will increase the accuracy of the main optimization task of improving the quality of simulated processes.
DISCRETE-TIME CONDITIONAL LINEAR RANDOM PROCESSES AND THEIR PROPERTIES
Authors:   Ternopil Ivan Puluj National Technical University, FRYZ Mykhailo , MLYNKO Bogdana ,   Ternopil Ivan Puluj National Technical University
Published: February 2023

Continuous-time conditional linear random process is represented as a stochastic integral of a random kernel driven by a process with independent increments. Such processes are used in the problems of mathematical modelling, computer simulation, and processing of stochastic signals, the physical nature of which generates them to be represented as the sum of many random impulses that occur at Poisson moments. Impulses are stochastically dependent functions, in contrast to another well-known mathematical model which is a linear random process, that has a similar structure but is represented as the sum of a large amount of independent random impulses that occur at Poisson moments of time. The application areas of these models are mathematical modelling, computer simulation, and processing of electroencephalographic signals, cardio signals, resource consumption processes (such as electricity consumption, water consumption, gas consumption), radar signals, etc. A discrete-time conditional linear random process has been defined in the paper, the relationships with corresponding continuous-time model has been shown. According to the given definition the discrete-time conditional linear random process can be considered as an output of linear digital filter with random parameters on the input of the white noise which is infinitely divisible distributed. Moment functions of first and second order have been analyzed. In particular, the expressions for mathematical expectation, variance and covariance function have been obtained. The results can be utilized to study the probabilistic characteristics of the investigated information stochastic signals, which will depend on the properties of the corresponding kernel and white noise. In particular, the conditions for the process to be wide-sense stationary have been represented.
COGENERATION DEVICE BASED ON INNOVATIVE TECHNOLOGY ORGANIZATION OF ORGANIC WASTE
Authors:   Khmelnytskyi National University, KOSIYUK Mykola
Published: February 2023

This work considers the issue of creating efficient and environmentally friendly energy systems based on cogeneration technology. In industrialized countries, work is underway to develop and implement innovative technology for supercritical hydrothermal destruction of industrial and household waste and highly toxic substances. An extremely important urgent task is the complex solution of the problems of creating an autonomous energy complex based on the technology of cogeneration and utilization of organic waste and their use as renewable energy sources. Theoretical and experimental studies have shown that the method of supercritical hydrothermal destruction has high environmental and economic efficiency and demonstrates versatility, providing complete one-stage disposal of any organic waste. It is established that the reaction of supercritical aqueous oxidation of organic matter is exothermic and in the presence of only 15-20% of organic matter the waste processing process becomes autothermal. Autothermal modes of destruction of organic waste at supercritical parameters of the aquatic environment lead to a high-enthalpy vapor-gas mixture, which can be used in the schemes of the autonomous energy complex. Cogeneration units are offered on the basis of a steam power plant operating on the Rankin cycle and on the basis of a heat engine with external heat supply, which operates on a closed thermodynamic Stirling cycle. A non-standard equipment of supercritical hydrothermal destruction technology is a quasi-flow reactor. The conducted research testifies to the possibility of further development of supercritical hydrothermal destruction technologies, both in terms of providing increased process parameters and in terms of developing increasingly reliable, productive and safe types of reactors. The development is based on the replacement of a single-pipe coaxial (two-pipe) reactor. This reactor design significantly expands the temperature and barometric performance characteristics, allows to increase the heat transfer surface and the temperature inside the reactor, bringing it closer to the external temperature of the reactor wall surface while maintaining performance. The cogeneration unit can be used to solve energy efficient and environmentally friendly disposal of organic waste. Allows to solve problems of autonomous electricity and heat supply of industrial and residential facilities and has significant market potential.

The development of the country is determined by the efficiency of enterprises and organizations, which should simply survive in difficult conditions, and pursue an active strategy of transformation. Innovations in the technology of protective and decorative metal coatings create the necessary level of competition in the domestic paint and varnish coating. Innovative development of the country’s economy is one of the highest priorities of state policy. The strategy of modernization is determined by the consistent transition of the economy to an innovative model of development to solve the problem of strategic support for sustainable and long-term dynamics of innovation processes. However, today there is no necessary level of competition in the domestic innovation market and entrepreneurs are aware of the importance of innovation in creating competitive advantages, as well as an adequate legal framework governing relations in the field of innovation. In addition, the generation of knowledge takes place in the public sphere, the application of this knowledge or the implementation of the obtained scientific and technical results is in the commercial industry. Metal has been and remains the main structural material of the industry – from means of production to consumer products, and the primary consumer properties of the product include its appearance and durability. Rust can kill these qualities in a matter of months and days, so perhaps more important is the quality of the product itself, and the quality of its coating. In this paper, an analysis of modern coating technologies is carried out, the strengths and weaknesses of different coating technologies are identified.

Published: February 2023

A typical approach for building and analyzing an object model is presented. It is determined that the tasks of analysis of nonlinear systems consist of: calculation of transients and established processes; determination of static and dynamic stability of the found processes; calculation of the sensitivity of the initial characteristics of the system to changes in its internal and external parameters. It is established that the efficiency of the analysis as a whole is determined not only by the efficiency of the algorithms of each of the stages of calculation, but also by the consistency of the mathematical apparatus that underlies them. It is determined that the calculation of transients is reduced to a problem with initial conditions in which the values of dependent variables are set for the same value of the independent variable, namely time. It is determined that nonlinear dynamic systems whose models are built on the qualitative theory of general differential equations are the main tool for solving many practical problems. It is established that this is explained by the following factors: the presence of a well-developed analytical apparatus and numerous methods of solving general differential equations; transparency and naturalness of general differential equations as a mathematical model to describe the process of transition of real objects from one state to another for external and internal causes; The availability of public qualitative methods of studying decisions of general differential equations, in particular methods of evaluation of stability, analysis of behavior within special points and their asymptotic behavior. The circumstances that lead to the fact that the systems described by conventional differential equations are a methodically very convenient material to create general algorithms for the study of dynamic systems. A mathematical model of sensitivity to the initial conditions is constructed on the basis of heterogeneous differential equations of the first variation, which opens up opportunities for solving the basic problems of analysis, which are: calculation of transitional processes and processes that have been established; Determination of static stability and calculation of parametric sensitivity, on the basis of a single algorithm for solving a two-point T-periodic marginal problem for conventional nonlinear differential equations.

Published: February 2023

La electrocardiografía es uno de los mayores métodos de detección para enfermedades cardiovasculares y el más utilizado alrededor del mundo, incluyendo Colombia y Nariño; sin embargo, en la actualidad se están generando nuevos métodos más avanzados, así como nuevas herramientas para el estudio de estas enfermedades; uno de los métodos nuevos es el Potencial de Mapeo de la Superficie de origen corporal, que propone un estudio mucho más denso y avanzado de los potenciales eléctricos corporales; utiliza cinco veces más electrodos que cualquier electrocardiógrafo convencional. Este prototipo cuenta con ciertas etapas parecidas a las de un electrocardiógrafo normal, sobre todo en la parte de amplificación y filtrado; sus etapas son las siguientes: adquisición de señales, protección del paciente, amplificadores de instrumentación, filtrado, conversión análogo-digital y procesamiento de señales. La primera etapa se encarga de adquirir las señales del paciente a través de los electrodos; posteriormente, esta señal es multiplexada y luego amplificada y filtrada; finalmente, se la convierte en una señal digital para procesarla. Así, en la región de Nariño se puede evidenciar una falta de equipos electrocardiográficos avanzados y una total carencia de equipos de ECG densos, que utilizan métodos como BSMP; por eso, es pertinente el desarrollo de este proyecto de innovación como una posible herramienta potencial para un mejor estudio de señales electrocardiográficas.

This article discusses the problems relating to change of the manner of prosecuting perpetrators of rape. By the Act of 13 June 2013 on Amendments to the Act – Criminal Code and the Act – Code of Criminal Procedure the legislator changed the manner in which rape is prosecuted: the offence is no longer prosecuted upon the victim’s motion, but by a state prosecutor ex officio. The article presents the reasons for the introduction of the change in question, as well as the views of Polish criminal law scholars on the issue. There is also an indication of amendments in the provisions relating to the manner of interviewing the victims of rape that were introduced by the amending act in point.
Czas popełnienia niejednochwilowych czynów zabronionych de lege lata i de lege ferenda
Authors: Nawrocki Mariusz
Published: February 2023

The article deals with the issue of how to determine the time of committing continuous offenses. This is a problematic issue, because there are different ways of determining this time and different consequences of the choice made in this regard. Particularly problematic is the heterogeneous judicial line of the Supreme Court, affecting non-uniformity of judicial decisions and doctrinal views. The article proposes amendments to the regulations that aim at unification of positions and leveling of accrued problems of interpretation both with regard to the manner of determining the time of committing continuous offenses, as well as the manner of determining the consequences of such acts.
Propozycja nowelizacji art. 12 Kodeksu karnego i sprzężona z nią propozycja nowelizacji art. 115 k.k.
Authors: Pohl Łukasz
Published: February 2023

This article suggests a change of the wording of Article 12 of the Criminal Code. The main change is replacement of the condition of ‘short time intervals’ with ‘a short time interval’. Such an approach has a sound axiological justification, because it rejects the possibility of considering acts that took place in the span of many years as constituting a single continuous offence. The proposal places also emphasis – by using the formula of ‘continuous offence’ – that the structure referred to in Article 12 of the Criminal Code is not so much an offence plus an additional feature of continuity, but rather a multitude of offences. Axiological considerations underpin also the recommendation to adopt a solution whereby the court has the power to impose an extraordinarily aggravated penalty for a continuous offence. On the other hand, the need to ensure certainty of the law requires the short time interval to be defined in the Criminal Code.
To See (Better) the International: Semiotics of the Image and the International Politics
Authors: Švantner Martin , Záhora Jakub
Published: February 2023

This article contributes to the research program of “visual turn” in International Relations (IR). It specifically engages Ronald Bleiker's methodological proposal which is rooted in assemblage thinking and calls for a comprehensive and pluralistic understanding of the relationship between visuality and politics. In this framework, semiotics should play a prominent role in attending to the role of images in (co)constituting the international politics. However, we show that Bleiker’s conceptualization of semiotics and its concepts is rather vague. The text therefore discusses how we can approach semiotics in a more rigorous way, and how the concepts of 'symbolism' and 'symbolic signs' can be understood from a semiotic perspective inspired mostly by work of Charles S. Peirce. The text thus offers theoretically sophisticated answer to Bleiker’s call for semiotically informed visual analysis. We illustrate our arguments by discussing scholarship on the politics of jihadist videos.

Fireweed (Urtica chamaedryoides) (Figure 1) is native to Florida, but has only recently become problematic. This winter annual species is commonly observed in north and central Florida pastures, particularly in bareground areas (near feeding pens and under fences), as well as along tree lines where forage grasses are less dense. This 2-page fact sheet is a minor revision written by B. Sellers, J. Ferrell, and P. Devkota, and published by the Agronomy Department, December 2019.

Thistle Control in Pastures
Authors: Sellers Brent , Devkota Pratap , Ferrell Jason
Published: February 2023

If left uncontrolled, thick thistle stands can reduce grazing, result in less forage production, and ultimately, lower calf weaning weight. A single thistle plant can produce at least 4,000 seeds, increasing the chance for higher thistle populations in the pasture the following year. Consequently, management practices need to be conducted prior to flower formation for effective thistle control. Even if thistles have not infested your pasture in the past, it is ideal that your pastures are scouted in late fall through mid-spring to ensure that thistles do not get out of control. New infestations are easier to manage than large-scale populations.
