Published: July 2023

Background. Symmetric slot lines on a perfectly reflecting half-plane are good mathematical models for slot antennas on an ideal plane of finite dimensions, which in practice have a high gain and operate over a wide frequency band. These antennas are used in ultra-fast information processing systems based on microwave and optical volume integrated circuits. Aim. The work presents a solution to the problem of radiation of a perfectly reflecting half-plane, which was excited by a symmetric slot line with a different law of slot expansion. Methods. The problem was solved by the Fourier variable separation method, by which the Green tensor function was obtained, which connects the two components of the antenna radiation field with the excitation field in the gap. Results. It is shown that in the far zone, the radiation field of an ideally reflecting half-plane has two components: the main and crosspolarization. The Green tensor function has a complex form and consists of two terms. The analysis of the Green tensor function shows the participation of each term in the formation of a field in the far zone, demonstrates the mechanism of radiation and leads to known special cases for slot radiators. Conclusion. The validity of the presented mathematical model is confirmed by experimental research.
La elección de los jueces constitucionales por los poderes del Estado y la preservación de la necesaria independencia
Authors: García-Cuevas Roque Elena 
Published: June 2023

Aunque no es una cuestión nueva, la situación de la independencia judicial en Europa ha provocado una inusitada atención. La designación de los jueces constitucionales ha suscitado intensos debates políticos, llegando a poner en tela de juicio la independencia del órgano jurisdiccional y la separación de poderes. A pesar de que la intervención de los poderes del Estado en dicha elección debería ser suficiente garantía para dar debido cumplimiento a los valores y principios democráticos, así como dotar a la institución de la legitimación necesaria, estamos asistiendo, desde hace años, a una mayor dificultad para evitar la influencia de las fuerzas políticas en la designación de estos jueces. Por este motivo, y en aras de la preservación del Estado de Derecho, es muy necesario insistir en la convicción de hacer primar el elemento técnico-jurídico sobre las consideraciones políticas, a la hora de aplicar los requisitos y exigencias previstos en los distintos ordenamientos.

En los laboratorios universitarios se generan datos que nutren las actividades de investigación y docencia; además, brindan soporte a diferentes sectores productivos y en algunos casos suministran información para la toma de decisiones con alcance legal. Por lo tanto, es necesario asegurar la calidad de sus resultados mediante la implementación de acciones tendientes al mejoramiento de sus mediciones; este sentido, el objetivo de este estudio fue desarrollar una estrategia para la calibración de equipos y cristalería de laboratorio de la Universidad Nacional de Costa Rica (UNA) con el fin de disminuir la brecha en materia de gestión metrológica. Entre los hallazgos más relevantes están que los laboratorios universitarios cuentan con poco o nulo presupuesto para la gestión metrológica de sus mediciones, lo que dificulta atender requerimientos como la calibración de equipos y la capacitación de personal. Además, dependen administrativamente de otras instancias universitarias como escuelas e institutos, lo que limita su capacidad de respuesta en materia de oferta de servicios a usuarios externos. En el caso específico de la UNA, se han realizado inversiones importantes en equipamiento y capacitación de personal. Sin embargo, no se han logrado abarcar todas las necesidades de trazabilidad de los laboratorios, lo que impide la completa gestión de la calidad de los resultados. Este estudio ha identificado mecanismos para que los laboratorios cuenten con mediciones trazables al Sistema Internacional de Unidades (SI), aumentando la confianza en sus resultados, permitiendo la detección de problemas e inclusive disminuyendo la presión económica por el rubro de calibraciones.

Online Audiences and Gatekeeping: User Comments and Their Infulence on Editorial Processes in Newsrooms in Kenya
Authors: Oywer Beryl Anyango , Booker Nancy , Owilla Hesbon Hansen , Kimweli Paul 
Published: July 2023

In Kenyan newsrooms, there has been a debate about keeping the comment section on news websites in the aftermath of Social Media Networks. This allows the media to still collect user opinions without the risk of unregulated third-party comments. This paper sought to establish the nature and influence user comments have on editorial processes and explain what value media houses that have retained the comment section are receiving. To investigate this, the researchers adopted mixed methods research approach (quantitative and qualitative) and concurrent mixed methods research designs. The targeted population was journalists working in media houses that operate in print, broadcast, and digital news websites in Nairobi County. The targeted media houses were: Nation Media Group (NMG), Standard Group (SG), and Radio Africa Group (RAG). The sample size comprised 252 participants for quantitative data, nine key informants for in-depth interviews, and 84 articles for direct content analysis. Surveys and directed content analysis were used as strategies of inquiry. These strategies were aided by questionnaires, in-depth interviews, and code sheets as data generation tools. Statistical Package for Social Sciences (IBM/SPSS) was used to analyse quantitative data. Quantitative data was presented using tables and pie charts. Qualitative data was thematically analysed and presented in the form of themes. Contrary to popular belief, the findings show that discussions in news website comment sections are frequently marred by incivility. Instead, most of the comments were deliberative, with audience members just looking for a forum to express themselves civilly. However, in cases with reported incidences of incivility, the sources quoted were the main trigger. Journalists have been shown to use user input in the comment section to gauge the quality of their content, while media companies use audience knowledge to make strategic decisions. The results shed light on how newsrooms may give the public a platform to discuss and give their input on the news while maintaining deliberative debates.
Efficiency of management of higher education in russia in the practices of application of managerial tools
Authors: Dyatlov Alexander , Kovalev Vitaly 
Published: June 2023

The managerial ideology for two decades of its use as a management model in the system of higher education in Russia has demonstrated its inefficiency. It has become a source of higher education losing its social purpose. The purpose of the study: to establish the ability of state managerialism to ensure the effective management of the Russian institution of higher education. Methodology: neo-institutional theory. Methods: document analysis; mass sociological survey among students and teachers; in-depth interviews with vice-rectors and deans of seventeen Russian universities. Hypothesis: the effectiveness of higher education management in the practice of applying managerialism is hindered by three barriers: 1) quality inversion, that can be caused by the disinterest of social actors to work effectively in the conditions of applying managerial ideology; 2) the mismatch between the managerial understanding of efficiency and the goals of higher education. In this case, we are talking about a deliberate rejection of the traditional goals of higher education for the sake of the formal implementation of managerial norms; 3) strict regulation of the work of the teaching staff, the reverse consequence of which is predicted to be the imitative fulfilment of the prescribed rules for the professional activities of students.
Three empirical indicators were used to test the hypothesis: intensification of educational and scientific activities; stimulation of inter-university and intra-university competition among employees; increasing the professionalisation of university management.
In the course of using survey methods, the effectiveness of state managerialism was refuted through the respondents' rejection of managerial values, the negative impact of institutional barriers on the process of achieving the goals of higher education, and the recognition of the neo-optimal (inefficient) nature of the use of budgetary funds. Instead of improving management efficiency, there is the emergence of imitative practices that are a direct consequence of formal adaptation to new institutional conditions. Professionals who are forced to adapt to managerial tools develop adaptive self-regulation strategies derived from their resource capabilities. As a result, new management tools operate in idle, on their own, in isolation from the target orientations of professional activity. This gives rise to a directly opposite effect on the goal conceived by the reformers: the effectiveness of management is reduced due to a sharp increase in the costs of using managerial tools and failure to achieve traditional professional goals. A paradoxical situation arises: according to formal signs, there is an increase in efficiency, but according to real results, a sharp decrease in the level of professionalism and expected social utility.
TESTING TECHNOLOGY OF THE UNDERCOUPLING SPACE FILLING OF COUPLING ON THE MAIN PIPELINE
Authors: Tymchik Gregory , Podolian Aleksandr , Serhiienko Kateryna 
Published: June 2023

Background. Now actively used the method of repair with the use of coupling metal structure. It is use to restore the carrying capacity of active pipelines that are working for a long time.
The coupling is installed on the defective area, and the undercoupling space is sealed and filled under pressure with a self-hardening mass. In this case, the stresses in the pipe walls and coupling are aligned with each other. The parameters of the filling process the undercoupling space determine the quality of the entire coupling repair and require precise testing.
Objective. The purpose of this article is to analyze the parameters for testing the filling of the under-coupling space using ultrasonic non-destructive testing methods.
Methods. Strength improvement of the spots of the active pipeline is realized by installing an active main pipeline of couplings. Strengthening the pipeline with the coupling is to redistribute part of the load from the pipe to the wall of the coupling, which leads to a decrease of the stress level in the pipe wall. The reinforcement efficiency of the pipeline could be evaluated by the degree of reduction of circumferential stresses in the wall of the repaired pipe. The article describes the analysis of the possibility of testing the filling of the under-coupling space of the glues-welded and brazed-welded couplings using ultrasonic methods of non-destructive testing.
Results. The use of the most common piezoelectric transducers is ineffective. This is due to the high temperature of the brazed-welded coupling during working using molten metal, determined by its melting temperature. In this case, it is proposed to use an electromagnetic (EMA) transducer as a radiator and receiver of ultrasonic vibrations. The results of theoretical and experimental studies of the control of filling the undercoupling space of soldered-on sleeves with molten metal have confirmed the effectiveness of using the EMA-method for controlling the formation of the undercoupling space. It is shown that the proposed method of ultrasonic testing allows to achieve maximum efficiency in testing the filling of the brazed-welded coupling with the molten metal.
Conclusions. The analysis of the possibility of using an ultrasonic method of non-destructive quality control of filling a undercoupling space with a self-hardening substance showed the theoretical possibility of testing the filling of the undercoupling space of glueswelded couplings with both the compounded filling of the undercoupling space and the filling with molten metal.
The results of experimental studies of the control of filling the under-coupling space of the glues-welded couplings with molten metal using the EMA-method confirmed the effectiveness of using the EMA-method for testing the formation of the undercoupling space.

Published: June 2023

Objectives. This study aims to evaluate the effectiveness of the Lean Six Sigma approach in improving procedure for (TAT) of reverse transcriptase polymerase chain reaction (RT-PCR) for SARS-CoV-2 testing at The Medical City. Specific objectives of the study are to determine the following: 1) baseline sigma and average TAT (in hours); 2) post-implementation sigma and average TAT (in hours) 3) compare if there is a significant improvement between baseline and post-implementation sigma and average TAT (in hours) 4) effect on workflow efficiency.
Methodology. Lean Six Sigma method for quality improvement was applied using DMAIC: Define, Measure, Improve, and Control. The root causes identified were lack of manpower, equipment, space, and manual and complex processes. Then, process wastes were identified, and corresponding proposed solutions were sustained in the control phase, such as standardization and the use of automation. Measurement of turn-around time and six sigma of the process were performed for evaluation.
Results. Results showed a significant improvement in the TAT in RT-PCR results, with most results released within 24 hours. The pre-Lean Six Sigma data on TAT were as follows: 24.88% released within 24 hours; 65.14% released within 24-48 hours; 3.56% released within 48-72 hours, and 6.42% released in more than 72 hours. The post Lean Six Sigma TAT were as follows: 95.32% released within 24 hours; 4.29% released within 24 to 48 hours; 0.13% released within 48-72 hours, and 0.12% released more than 72 hours. The computed sigma post-implementation was increased from 3.56 to 4.82. The p-value was calculated using the chi-square test, and the computed chi-square statistic is 1894.1021. The p-value is <0.00001 and the result is significant at p<.05. Although there is a significant decrease in the volume of samples post implementation due to the changing COVID19 situation, real time TAT was improved. It also resulted to increased workflow efficiency with the use of lesser manpower with more appropriate utilization.
Conclusion. Applying the Lean Six Sigma method to improve quality processes in the laboratory is shown to be practical, cost-effective, and straightforward.
