Authors: Cuero Granobles Luis Felipe , Gutiérrez Marroquín William , Londoño Iván Miguel 
Published: October 2021

La transformación digital de los procesos industriales está enfocada inicialmente a la obtención de datos del proceso, para posteriormente convertirlos en información que permita tomar decisiones oportunas, para obtener mejoras en la cadena de valor del proceso. La comunicación máquina - máquina, M2M, está orientada al intercambio de información entre las maquinas en un proceso industrial, lo cual ha permitido implementar sistemas de control distribuido. El internet de las cosas, IoT, tecnología propuesta desde industria 4.0, está planteando la posibilidad de comunicación no solo a nivel de máquinas, sino también la comunicación con los clientes, los proveedores, con todos los actores en la cadena de valor de la empresa. Esta comunicación horizontal y vertical se está logrando a través de protocolos de comunicación como MQTT, RFID, OPC UA, protocolos basados en Ethernet IP, objeto de estudio en el presente proyecto.
En este artículo se presenta la caracterización de algunos de los protocolos de comunicación utilizados en IoT, para lo cual se utilizan aplicaciones de simulación para obtener y validar información proveniente de sensores y actuadores de una línea de fabricación; al realizar el análisis de la evaluación de cada uno de los protocolos que se utilizaron para este estudio se determina las altas prestaciones del protocolo OPC UA, sobre los otros estudiados. OPC UA es una alternativa bastante viable para la comunicación, soportado en su fácil implementación, está embebido en un número considerable de autómatas programables como los PLC S7 1500, de Siemens, los PLC BOSCH, además su velocidad de comunicación, como el tamaño de paquete que soporta, permite ajustarse a las necesidades de un entorno IIoT.

Las prácticas pedagógicas con enfoque diferencial en el Sena y la comunicación aumentativa y alternativa
Authors: Galindo Bejarano Leonor 
Published: October 2021

La Comunicación Aumentativa y Alternativa es un ámbito de trabajo e investigación interdisciplinar relativamente reciente en Colombia (años 90), cuyo objetivo se orienta a posibilitar otras formas de comunicación diferentes a la oral a aquellas personas que por diferentes razones se les dificulta o se les imposibilita dicho proceso. La importancia de este campo y sus posibilidades en el desarrollo de una de las dimensiones humanas como lo es la comunicación, esta es una de las principales razones que determinó que un equipo docente de la Universidad Pedagógica Nacional en 2013 se diera a la tarea de iniciar una investigación en este campo, poco explorado en nuestro medio sobre las huellas existentes alrededor de la misma y su uso, tanto en escenarios educativos como de familia. Para ello se trazó como objetivo principal sistematizar experiencias de concepciones y usos cotidianos de la comunicación Aumentativa y Alternativa de maestros, familiares y personas con discapacidad. El presente documento pretende esbozar la posible articulación de los resultados de dicha investigación, con las prácticas pedagógicas con enfoque diferencial aplicables en la Formación Profesional Integral del SENA (FPI), en la medida en que uno de los ejes con los que se inicia esta política en la Resolución 1726 (SENA, 2014) es la gestión del talento humano de la institución en cuanto a su cualificación en este sentido. Por otra parte, dentro de los procesos misionales a los que se refiere la resolución está: “crear y fortalecer ambientes de formación para la atención con enfoque diferencial bajo el principio de diseño para todos”, misión que puede ser abordada desde este campo interdisciplinar, el cual posee una producción teórica amplia, unas estrategias de intervención, unos sistemas de signos y ayudas técnicas que contribuyen con el logro de este propósito, en la medida en que aportan con el uso de otros lenguajes diferentes al oral en las prácticas pedagógicas, así como desde los usos y representaciones que de ella se hacen en el contexto colombiano, los cuales pueden dar luz sobre la forma como se pueden configurar los programas de formación y enriquecer las prácticas pedagógicas desde la realidad que sobre este tema se vive en nuestro medio.
La nulidad del crédito de Argentina con el Fondo Monetario Internacional
Authors: Bernal Andrés , Martinelli Augusto , Verbic Francisco 
Published: October 2021

El trabajo analiza las condiciones legales y de procedimiento en base a las cuales, en junio de 2018, la República Argentina contrajo con el Fondo Monetario Internacional (FMI) un crédito stand-by por la suma de $50.000.000.000, ampliado posteriormente por U$S 7.100.000.000. También explica las acciones desarrolladas en términos de litigio estratégico para obtener información pública sobre el tema y sostiene, tal como se encuentra pedido judicialmente, que el crédito y su ampliación es nulo de nulidad manifiesta y absoluta. Esta nulidad deriva no solo por el hecho de que el crédito fue tomado por el Poder Ejecutivo sin intervención del Congreso, sino por haberse violado de manera manifiesta diversas leyes nacionales. En especial, requisitos esenciales establecidos por la Ley de Administración Financiera N° 24.156 (LAF) y la Ley Nacional de Procedimiento Administrativo N° 19.549 (LNPA).

Abstract
Land use and land cover change (LULCC) are the result of different interacting socio-economic and environmental causes and consequences that have been known since the beginning of agriculture. The study intended to explore the implications and drivers of LULCC in the Ethiopian rift valley region of Gidabo river sub basin from 1986 to 2019. The researchers have triangulated the data from Landsat 5 (™), and Landsat 8 (OLI) with data obtained from key informants, focus groups and field observation, which is helpful to determine the interaction between the environment and the community. It is also important to mitigate environmental disaster (erosion, landslides, and climate change) and sustainable utilization of natural resources. The LULCC of the past 33 years implied that about 58.4 % of the area was changed to other Land use land cover (LULC) classes. This refers to the fact that about 14% of agroforestry, 2% of the settlement, 1.1% of the forest, and 1% of bare land were expanded at the expense of 10.3% of shrub/woodland, 6.3 % of grassland, and 1% of cropland classes. Therefore, as a result, the highest land cover (46.7%) was observed on the agroforestry system. Participants in group discussion and informant interviews attributed the expansion of agroforestry to the drivers, such as population density, cultural values (Songo, Babbo), traditional beliefs, land policy, and the insecurity resulting from climate change. Whereas, the drivers related to unproductive land, resettlement, urbanisation, and lack of agricultural inputs were considered as threats that will adversely affect the agroforestry system of the area. The study concluded that the high expansion of the agroforestry system has significant contribution to achieve a resilient environment and sustainable development, which integrates the socio-economic and environmental needs of the community. But greater attention should be given to the changes observed in shrub/woodland, grassland, and bare land to enhance environmental protection.

Published: October 2021

ТНЕ PURPOSE. To carry out a comparative analysis of the performance characteristics of the longitudinal movement guides of the external bearing housings of steam turbines, using the principle of rotation to ensure full contact of their lateral surfaces with the lateral surfaces of the guide groove at the base of the external bearing housing of the steam turbine. Compare the manufacturability of elements and their implementation for both existing and newly developed steam turbines .METHODS. The permissible transverse forces are determined from the strength conditions and compared for the traditional design of fixed longitudinal guides and the design of guides, in which the principle of rotation is used to avoid "biting" of the bearing housing on the guides when temperature misalignment appears along the flanges of the turbine cylinder. Also, the allowable forces are determined and compared from the condition of the absence of plastic deformations in any of the elements of the interface of the guides, the base frame and the bearing housing. Based on the results obtained, the value of the permissible temperature misalignment along the flanges of the turbine cylinder is estimated. The analysis was carried out in relation to the operating conditions of the front bearing housing and HPC of turbines of the T 100/120-130 UTZ family.RESULTS. It has been established that all the considered designs of guides with pivoting elements make it possible to exclude the occurrence of plastic deformations in the junction of the base frame and the outboard bearing housing at a temperature misalignment of 20°C regulated in most turbine operating instructions. CONCLUSION. The design of longitudinal keys proposed by UTZ does not require a change in the technology for manufacturing the foundation frames and allows the unit to be modernized during repairs in a CHP. The best performance disc guide design can be used in new turbine designs or factory retrofits.

THEPURPOSE.To develop and investigate a mathematical model of an operating object – an individual heat point with two methods of controlling the temperature of the coolant. In the first case, the control of the temperature of the coolant is considered, with the help of a control valve installed on a real object. In the second case, a more reliable and less energy-consuming solution is proposed – replacing the control valve with a frequency- controlled electric drive operating according to the proposed optimal algorithm.METHODS.Whensolvingthisproblem,themethodofcomputersimulationmodeling,implementedby means of Matlab Simulink, was used.RESULTS.Thearticledealswiththeproblemsthat arise during the operation of an individual heating point. Possible solutions to the problemassociatedwiththefailure ofthecontrolvalve are given. A solution for regulating the temperature of the coolant is proposed, based on the use of a frequency-controlled electric drive of the electric pump. To implement the proposed solution, no redevelopment of the premises is required, only the installation of a frequency converter on the pump already available in the device of an individual heat station is necessary.CONCLUSION. Theconductedresearchhasa practical focus, since the proposed solution is implemented at the existing facility. The use of a frequency-controlled electric drive of a centrifugal pump made it possible to increase the reliability of the existing facility. The results obtained during the simulation allow us to draw a conclusion about the feasibility of using the proposed solution.

The influence of the last stage blades swirl to the efficiency of «stage-diffuser» unit of stationary GTU
Authors: Vokin L O. , Semakina E Yu , Chernikov V. A. 
Published: October 2021

THE PURPOSE. Determination of the optimal law of swirling of the blades of the last stage of a stationary GTU. Due to the specificity of its operating conditions - in a system with a diffuser - the traditional laws of swirling lead to a non-optimal flow in the diffuser and, consequently, reduce the efficiency of the entire unit and the power plant as a whole. In this paper, we used numerical and experimental methods for studying a three-dimensional flow. Two stages with different laws of swirling were investigated - with the traditional law of constancy of the angle of flow out of the guide vanes along the radius, and with reverse swirling. The same diffuser was used in both cases. METHODS. Experimental studies were carried out using pneumometric five-channel probes of an original design on an ET-4 aerodynamic stand in the Turbomachinery laboratory of SPbPU. Numerical studies were carried out in the CFX gas dynamic calculation package; the parameters in the corresponding sections, obtained during the physical experiment, were used as boundary conditions.RESULTS. Integral characteristics of the stage, the vector of flow velocities in various sections were obtained. The experiment was compared with the numerical calculation and showed satisfactory convergence of the results. CONCLUSION. The optimal swirling law for the last stage operating in a system with a diffuser is forced vortex flow.
Aristotelian and Stoic Syllogistic in the Anonymous Commentary on Plato’s Theaetetus
Authors: Hene Bernd 
Published: October 2021

Abstract
The present paper investigates the question as to how and for what purposes the Middle Platonic author of the Anonymous Commentary on Plato’s Theaetetus uses Aristotelian and Stoic syllogistic in his interpretation of the Platonic text. This investigation shows that the commentator employs Aristotelian categorical syllogistic as an exegetical tool for reconstructing arguments in the Platonic text, enabling him not only to uncover doctrinal statements that are in his view hidden in the Platonic text, but also to dissociate Plato from unwelcome propositions. By contrast, the commentator uses Stoic hypothetical syllogistic as a polemical tool for constructing ad hominem arguments against the Stoics. More precisely, the author exploits the Stoic type of deductive reasoning to draw anti-Stoic conclusions from premises that are accepted by the Stoics, and in doing so, he manages not only to refute Stoic doctrines, but also to corroborate the corresponding Platonic theories.

Restorative Justice Crime Against Child Actors In The Perspective Of Justice Theft Dignified
Authors: Puspitosari Hervina 
Published: October 2021

Abstract
Various factors the cause of children committing crimes, especially in this discussion are children who are perpetrators of the crime of theft. Various problems of children as perpetrators of criminal acts of theft that occur. The act of a child committing theft is a violation of the law and has been regulated in the Criminal Code as formulated in the provisions of Articles 362, 363 and 365 of the Criminal Code. Various negative impacts of imposing punishment on children who commit the crime of theft causing dehumanization (decreased human values), prisonization (the influence of learning crime) and stigmatization (bad labels) are also taken into consideration in encouraging the birth of a diversion policy in Indonesia. The problem that arises is how the application of diversion to child perpetrators of the crime of theft is made aware of restorative justice in the perspective of dignified justice that prioritizes the future of the child. In child protection, there are 4 basic principles, namely: non-discrimination; the best interests of the child; survival, growth and development, respect for children's opinions. Thus, in the perspective of child protection, there is no punishment for children and there is no prison for children. So that in cases of children, perpetrators of the crime of theft should prioritize diversion against children with more emphasis on dignified justice for children.
