Failure to comply with the above requirements will inevitably lead to the inability to manage units, and as a consequence to the failure of operational-search activities.
Navigation in networks and its information support
Authors:   Solomenko Institute of Transport Problems of the Russian Academy of Sciences, Bobrik P.P.
Published: March 2024

Summary: The tasks of navigation and orientation in networks, as well as their information support, are considered. The question is focused on the cost and complexity of the necessary information for movement. For a square network, it is shown that it is sufficient to use the simplest navigation rules to move along it in an optimal way, without preliminary calculating the shortest routes. Which greatly simplifies and reduces the cost of movement. Generalizations of the square network that preserve similar properties are considered. The concepts of azimuthal navigation and azimuthal subnet are introduced. The variants of local information about possible directions of further movement during azimuthal navigation in the network are proposed.

The use of Universal (Control) Characteristics of Vane Blowers for an Objective Assessment of the Energy Efficiency of Pumping Systems
Authors: Nikolaev Valentin G. , Nikolaev Georgy V.
Published: March 2024

This article describes the methodology for assessing the energy efficiency of pumping systems equipped with a variable electric drive and operating with variable load, which was elaborated by the authors of the article. The analysis of traditional methods of recalculating the characteristics of the efficiency of pumping units when changing the frequency of rotation of the impeller using the formulas of theories of hydrodynamic similarity of blade blowers is presented. It is shown that in the derivation of the similarity formulas assumptions were made, which were not fully confirmed later when testing operating pumps. An algorithm and a technique developed by the authors are presented that allow one to read the actual values of the efficiency from the pre-digitized universal characteristics of vane blowers The results of comparison of efficiency values calculated by different methods are presented.
The Free Movement of People in SADC: Reflecting on the Experiences, Dilemmas and Strategic Considerations
Authors: Vhumbunu Clayton
Published: March 2024

The Southern African Development Community (SADC) member states committed under Article 5(2) (d) of the SADC Treaty to develop policies aimed at the progressive elimination of the obstacles to the free movement of capital, labour, goods and services. The 2005 SADC Protocol on the Movement of People was celebrated as a giant step towards the realization of the regional integration objective of building SADC into a regional community that is fully integrated where citizens enjoy the freedom of movement across regional borders. Whilst substantial efforts have been invested in developing various legal and policy frameworks to open up borders for the free movement of people within SADC, thirty (30) years since the formation of SADC in April 1980 as the Southern African Development Coordination Conference (SADCC); the region is facing serious challenges relating to the free movement of people, migration and labour movement. In reality, SADC member states’ governments have been confronted with serious feasibility challenges, complexities, risks and dilemmas as they attempt to implement commitments made towards the free movement of people in the region, with political, security, economic, strategic, and technical factors often cited as obstacles. This paper sought to critically reflect on the feasibility aspects, policy dilemmas at member state level as well as strategic considerations that stand on the way of free movement of people in SADC. The focus was on examining possibilities, capacities and prospects of SADC member states (in their collectivity and individuality) in addressing the underlying, structural and operational obstacles that are impeding the free movement of people in the region. Secondary data sources are used for analysis, and the concept of free movement of people, migration provides conceptual lenses for analysis. Findings are key in providing perspectives on how SADC member states may need to collectively address the fundamental questions and issues that facilitate the free movement of people in the region.

Africa’s Role in the G20
Authors: Gopaul Pamla , Oluoch Juliet
Published: March 2024

The G20, a pivotal player in global governance since 1999, has recently included the African Union (AU) as a permanent member, enhancing its representativeness and legitimacy. This historic development presents both opportunities and challenges for Africa. The AU’s membership will foster collaboration between Africa, other developing countries, and economic powers, advancing Africa’s contribution to global governance. At the same time it will be a good opportunity to show the potential for Africa toshare and advance its transformative roadmap captured in its Agenda 2063. However, representing a diverse continent with 18% of the global population will require immense collaboration and consensus building within Africa. Even more, the AU could also face pressure from G20 members to align with their interests, which may not always be compatible with Africa’s priorities.

With the systematic exposure of disinfectants (DS) to cholera vibrions, they can adapt by forming biofilms fixed on various surfaces. The aim of the work is to evaluate the effect of DS on the stage of formation of V. cholerae O1 and O139 serogroups biofilms on biotic and abiotic substrates. Materials and methods. Combined and monobiofilms were obtained according to previously developed methods, the concentration of V. cholerae of planktonic and biofilm forms was evaluated by bacteriological method and polymerase chain reaction in real time (PCR-RV). The statistical significance of the differences in experimental data was assessed using Student criteria. Results. At the stage of cell adhesion, cholera vibrions in the combined biofilm showed resistance to the action of ethyl alcohol (10 and 20?%), chloramine (0.1 and 0.2?%) at exposure up to 20 min. The bactericidal effect, expressed in the absence of culture growth and positive results in PCR-RV, was observed in samples with the addition of hydrogen peroxide of all dilutions, ethyl alcohol (50?%) and chloramine (0.5 and 1.0?%). At the monolayer stage, resistance to the action of ethyl alcohol of all dilutions, hydrogen peroxide (0.1 and 0.2?%) was revealed at exposure up to 20 minutes. Under the action of chloramine of all dilutions and hydrogen peroxide (0.5 and 1.0?%), the absence of V. cholerae growth on agar was noted with positive values of their concentrations in PCR-RV. The effect of all DS on mature biofilms maintained the previous pattern. Abio- and biotic biofilms of V. cholerae O139 ctxAB?¬ and ctxAB+ showed resistance to ethyl alcohol of all dilutions, chloramine (0.1 and 0.2?%) at exposure up to 30 min. The bactericidal effect of hydrogen peroxide of all concentrations on abiotic biofilms of all strains and resistance of strains in biotic biofilms were noted. It is advisable to continue studying the effect of DS on vibrio cholera biofilms due to the possible «selection» of strains with increased resistance in the environment. Keywords: biofilms, stages, Vibrio cholerae, disinfectants.

The COVID-19 pandemic had an impact on all spheres of public health. The multiplied load on medical organizations, forced use of unsuitable premises for treatment of people could not but affect disinfection activities. In addition, given the closed borders in 2020, there was a shortage of both raw materials and ready disinfectants on the market. On the one hand, this situation has led to an explosive interest of the business community in the disinfectants market. This is evidenced by the increased number of disinfectants registered in the Russian Federation from 164 in 2019 to 467 and 471 in 2020 and 2021, respectively. In this study, we analyzed technical specifications for the procurement of disinfectants by medical organizations posted on www.zakupki.gov.ru. Despite the fact that during the period there were relaxations in the procurement legislation that allowed medical organizations to directly purchase disinfectants from suppliers, the analysis revealed significant deviations in 2020 and 2021 in the consumption of disinfectants compared to 2017–2019 and 2022. For example, the consumption of disinfectants based on sodium hypochlorite increased significantly. Also, with the shortage and increased cost of alcohol-based skin antiseptics, purchases of soaps with antibacterial properties have increased, which is especially noticeable in 2021. However, the 2022 purchases indicate that healthcare organizations are returning to normal operations and their consumption of disinfectants is becoming similar to that seen in 2017–2019. Keywords: disinfectants, auctions, hospital-acquired infection.

The article presents the results of a comprehensive analysis of the organization of planned measures to comply with the sanitary and hygienic regime at the training complex of the cynological faculty of the Military Institute in the period from 2017 to 2023. The study shows that the cynological town is an artificial ecological system, which is a complex system of compartments (functional zones), the interaction of which, on the one hand, forms a continuous circulation of pathogenic biological origin, on the other hand, provides localization of processes, which, with proper organization of the sanitary regime, allows solving the problem of non-proliferation of infectious origin in the «man» system. – animal – epidemiologically significant surfaces, environments.» As a result of the conducted research, the links of the epizootic chain in each functional zone of the cynological town are identified and described; the role and responsibilities of the daily outfit in maintaining internal order are formulated; the duties of military personnel to maintain the sanitary and hygienic regime at the cynological town are described; an algorithm for observing the sanitary and hygienic regime by the daily outfit and military personnel of the cynological unit in daily activities according to the main tasks is developed and areas of training of specialists of cynological services. The developed recommendations make it possible to adjust sanitary and hygienic measures at the dog training camp, are of great importance in solving health-saving issues and maintaining the livestock of dogs of service breeds. Keywords: sanitary and hygienic regime, dog training camp, epizootic process, preventive disinfection, health care.

Published: March 2024

Introducción: la Diabetes Mellitus (DM) es un desorden metabólico, caracterizado por hiperglucemia crónica con alteraciones del metabolismo de los carbohidratos, grasas y proteínas, resultante de la disminución de la secreción y/o acción de la insulina. Un manejo inadecuado de la enfermedad aumenta el riesgo cardiovascular, y se acompaña de lesiones microvasculares (retina, riñón, nervios) y macrovasculares (cerebro, corazón, miembros inferiores). El plan de alimentación se debe seguir a largo plazo, siendo fundamental una adecuada educación diabetológica. Objetivo: Conocer el impacto del consumo de un pan artesanal enriquecido con harina de garbanzo, en la glucemia postprandial de individuos adultos con DM2 no medicada con insulina y compararlo con un pan blanco artesanal. Hipótesis:El consumo de un pan elaborado con 15% de harina de garbanzo y 85% de harina de trigo disminuiría significativamente la glucemia postprandial respecto del pan blanco artesanal. Materiales y métodos:tipo de estudio de diseño prospectivo analítico con evaluación de impacto de una intervención, en individuos adultos que pertenecían al personal profesional y no profesional del H. Oñativia de R. Calzada, Provincia de Buenos Aires durante los meses de Octubre a Diciembre de 2019. Resultados: se evaluaron 24 individuos. 13 con DBT2 sin tratamiento con insulina y 11 sanos; con una edad media de 49.5 años y una mediana de 7 años de antigüedad con la enfermedad.El ANOVA de mediciones repetidas, para comparar el cambio en la glucemia pre-post prandial con pan blanco de referencia (HT) y pan con reemplazo del 15% por harina de garbanzo(HG)mostró un aumento significativo en la glucemia postprandial (p:<0,001) sin diferencias de magnitud entre el tipo de pan.No se observó una diferencia significativa (p = 0,07) entre las glucemias pre y postprandial luego del consumo tanto de pan con HT como del pan modificado con HG. Conclusión: El pan artesanal con 15% de HG y 85% de HT presentó un alto nivel de aceptación en la población estudiada, basado principalmente en apariencia, obteniendo un pan de calidad nutricional superior al tradicional.En los sujetos estudiados el consumo de un pan artesanal elaborado con 15% de Harina de Garbanzo y 85% de Harina de Trigo, no mostró una disminución significativa en la variación de la glucemia pre - posprandial en individuos con DM2 sin tratamiento con insulina, refutando la hipótesis planteada en este estudio.
