Mathematical Model of Frequency Inverter with Autonomous Voltage Inverter
Authors:   Siberian Federal University, Fedorenko Aleksandr A.
Published: March 2022

An analytical analysis of the processes occurring in the systems of an electric drive with a frequency converter, which are characterized by discrete, nonlinear properties, is practically impossible. This predetermines the need to use methods of mathematical modeling and mathematical experiment to study the properties of such systems. Purpose of the work: building a model of a frequency converter with formalization in the form of mathematical relationships of the relationships between the variables characterizing its functioning, based on the analysis of physical processes in each of its elements. Mathematical models of each element must be represented by structural diagrams, which are subsequently combined into a common block diagram of the frequency converter in accordance with the method of structural modeling. Research methods: to solve the set tasks, the methods of the theory of electronics and electrical engineering, induction devices and the concept of switching functions were used. Software implementations of the proposed mathematical models and numerical studies of the processes reproduced by them were performed in the MATLAB computing environment (SIMULINK application software package). Results: the method of structural modeling made it possible to create a fairly universal and flexible version of a complete mathematical model of a frequency converter, due to the possibility of a fairly simple inclusion in it of various options for mathematical models of elements included in a specific real frequency converter. In this case, the resulting model preserves the topology of a real frequency converter and the observability of all its real physical variables. The use of the theory of induction devices and the concept of switching functions made it possible, on a single methodological basis, to create physically and mathematically grounded mathematical models of all the main elements of the frequency converter. The constructed model makes it possible to clarify the relationship between the physical variables of the individual elements of the frequency converter and their mutual influence
İslam İktisadı ve Metodolojik Bireycilik: Homoİslamicus Kavramının Eleştirel Bir Değerlendirmesi
Authors: YILMAZ İsa
Published: March 2022

Bu çalışma, neoklasik iktisadın metodolojik bireycilik varsayımının modern dönem İslam iktisadı literatüründeki izdüşümlerini ele almaktadır. Bu bağlamda, neoklasik iktisatta homoeconomicus olarak tasvir edilen insan tekine karşı geliştirilen homoİslamicus kavramının her ne kadar İslam iktisadını ana akım iktisattan ayrıştırdığı iddia edilse de her iki yaklaşımın da metodolojik bireyci bir varsayımdan yola çıktığı ve bu yüzden benzer bir metodolojiyi takip ettiği tartışılmaktadır. Neoklasik iktisadın bireyden yola çıkan ve birey ile sınırlı yaklaşımının geliştirilen homoİslamicus kavramı üzerinden benimsenmesi İslam iktisadının özgün bir alternatif iktisadi sistem olarak gelişmesinde sınırlı bir etki yaratmaktadır. Diğer yandan, bireylerden yola çıkmayan, ancak toplumsal refah ve gelişme adına insan iyiliğini ve felahını göz ardı eden holistik yaklaşımlar da benzer şekilde problemlidir. Bu çalışma her iki tutumun ötesinde ahlak temelli bir İslam iktisat metodolojisi önermektedir. Bu bağlamda, Polanyi’nin gömülü olma kavramı ve Bourdieu’nun alan teorisinden yola çıkarak İslam iktisadında bireyci ya da holist yaklaşımların ötesinde ahlak temelli bir İslam iktisat metodolojisinin geliştirilmesine katkıda bulunmak amaçlanmıştır.
Co-Designing Urban Planning Engagement and Innovation: Using LEGO® to Facilitate Collaboration, Participation and Ideas
Authors: Tewdwr-Jones Mark , Wilson Alexander
Published: March 2022

There is a growing academic interest in the idea of co-designing methods to achieve urban innovation and urban planning. As we see cities as “living laboratories,” beyond the control of elected city government, there is a momentum to develop and test shared responses to the social, environmental, and economic challenges present in contemporary urbanism. These living laboratories are a function of open innovation or “quadruple helix” actors, drawn from state, business, higher education, and community sectors. However, translating the often-good intention principles of working together through shared and co-designed arrangements in any major urban area is often a significant challenge and a topic neglected to date. This article addresses this gap through the case study of Newcastle City Futures, a university-anchored platform in the northeast of the UK, that sought to co-design collaborative urban research, public engagement, and innovation. Newcastle City Futures created novel working methods centred on participatory games to facilitate shared understanding and joint ideas for new urban innovation projects across established sectors. This article will examine one method that was successful in generating collaboration and participation: “LEGO® mash-ups.” Detailed empirical accounts of the development of the LEGO® mash-up method are used to illustrate attitudes to urban challenges, the fostering of a spirit of open collaboration, and the development of innovative responses through co-design. These are used to support the conceptual argument that the use of the quadruple helix as a form of urban innovation system needs to be accompanied by accessible, workable, and easily interpreted translation methods, such as games, by intermediaries.

Las imágenes como fuente de memoria: el estudio de caso de la Iglesia de São João Baptista da Foz do Douro
Authors: Faria dos Santos Marisa Pereira
Published: March 2022

El culto a Cristo, la Virgen y los Santos influye directamente en la producción y difusión de imágenes, encuadrándose en prácticas y rituales devocionales que marcan el ritmo del paso del tiempo, guiados por las festividades religiosas. Las imágenes están sujetas a una movilidad determinada por las transformaciones de la liturgia, la arquitectura y el espacio urbano. Partiendo del estudio de caso de la Iglesia de São João Baptista da Foz do Douro, buscamos demostrar la importancia que el estudio de las imágenes asume en la comprensión evolutiva del espacio sagrado y el paisaje urbano, así como en la perpetuación de la memoria benedictina y las vivencias de la pesca comunitaria, factores determinantes para el establecimiento de devociones vinculadas a la Orden y la protección de los marineros en este territorio.
La Carta de Privilegio para la venta de las casas del comunero Hernando de Ávalos: el arte de la miniatura en los códices jurídicos españoles de principios del siglo XVI
Authors: Moraleda Moraleda Jaime
Published: March 2022

En el marco del quinto centenario de la revuelta comunera han sido numerosas las aportaciones por parte de la historiografía nacional, si bien, entre algunos ejemplos documentales no considerados está la Carta de privilegio para la venta de las casas de Hernando de Ávalos, conservada en el convento toledano de San Antonio. Con este artículo pretendemos contextualizar la importancia del simbolismo que pretendió su alumbramiento, así como la manufactura del trabajo de iluminación que destaca en su primer folio. El análisis de sus miniaturas y la comparativa con otros ejemplos de naturaleza jurídica nos permite establecer algunas conclusiones en cuanto al valor de la técnica de iluminación, los repertorios y los modelos utilizados en Castilla a principios de la centuria del Quinientos.

Taxes and mortgages were the most popular credit formulae all throughout the Modern Age in the province of LEON. Although they share a common aim, there are important differences between them, both as to the dynamics and function which extend loans. Besides, taxes enjoyed a wide success, aboye all in the l8th. century.These formulae through which peasants ran finto debt gave birth to new relationships of dependence in society. The group of creditors is made up by the clergy, the industrial bourgeoisie and the aristocracy.On the other hand, loans did not help to introduce improvements in structures and techniques -but they contributed to the keeping up of a subsistence level of production and to produce a bigger income to privileged classes

The corps of "Voluntarios Realistas" was one fundamental pillar of the contrarevolution during the second absolutist restoration (1.823 - 1.833). Since the beginning a strong group of "Voluntarios" from Leon became the main support to the radical absolutism. They would be helped by the local clergymen and their bishop Joaquín Abarca.The "Voluntarios" came into riots several times with the Army, the Police, the conscriptions and even with the king Fernando VII, good example of these was the oustanding revolt in jannuary 1.833. The group was only not rnade by lower class subjects (crafmen and labourers) but also by some members of the local aristocracy and bourgeoise.The above mentioned revolt was lead by retired militaries and clergymen. After the rebellion failure the most notorions members took refuge in Portugal.

The analysis of three works of the Romantic French Art (the Symphonie Fantastique by Berlioz, Notre Dame de Paris, by Victor Hugo, and Liberty Leading the People, by Delacroix), shows and proves the existence of deep structural and thematical analogies in them. The coincidences in the conception of the Feminine and its relationship with the idea of artist are not anecdotal, and could be explained by different hypothesis. Firstly, as a result of conscious influences among the three artists. Secondly, as manifestations of the period's latent culture and, finally, as three formal mouldings of the anima archetype.

Weigh-in time affects hydration status and acute weight gain in combat sports: A comparison of judo and wrestling
Authors: Ceylan Bayram , Baydil Bilgehan , Aydos Latif
Published: March 2022

This study aimed to investigate the effect of weigh-in time on hydration status and acute weight gain (AWG). Twenty-seven men judo athletes and 23 men wrestlers voluntarily participated in this study. Body mass and urine specific gravity (USG) of the athletes were measured just before official weigh-in and competition. Two-way analysis of variance (split-plot ANOVA) with repeated measurements (time x sport) were used to determine differences in AWG and USG between groups and measurement times. In case of significant difference between sports, t-tests were applied. There was a significant main effect of time (p<0.01, ES=0.25) on USG. A significant difference was found in USG between official weigh-in and start of the competition in wrestlers (p<0.01) but not in judo athletes. There was significant difference in AWG and AWG% between sports (p<0.01). Moreover, most of the athletes presented high level of dehydration before both official weigh-in and competition. In conclusion, judo athletes could not rehydrate as much as wrestlers despite 15h of recovery. It can be suggested that the period between official weigh-in and competition would be shortened to prevent non-optimal hydration status and rapid weight gain, with caution to allow sufficient recovery period.
El Poder Judicial en el marco del principio de unidad y del Estado de las Autonomías = The Judiciary within the framework of the principle of unity and the State of Autonomy
Authors: González Granda Piedad
Published: March 2022

La tradición del Poder Judicial está anclada en una estructura organizativa estatal unitaria, que la Constitución española (CE) modifica a través de un sistema de gran complejidad jurídica que supone la plasmación de la integración de un Poder Judicial unitario en el modelo de un Estado Autonómico o de las Autonomías. La coordinación entre los Títulos VI y VIII no ha estado exenta de problemas en ningún momento. El objeto del presente trabajo constituye un breve análisis del entramado constitucional del Poder Judicial y la pertinente clarificación en torno al principio de Unidad jurisdiccional, que -contrariamente a lo que a veces venos reflejado en artículos de opinión- no guarda relación directa con el diseño del Estado de las Autonomías, siendo otra la problemática de interés que suscita el modelo territorial autonómico: la debida interpretación de las limitaciones constitucionales afectantes al concepto de Administración de Justicia. The tradition of the Judicial Power is anchored in a unitary state organizational structure, which the Spanish Constitution (CE) modifies through a system of great legal complexity that implies the embodiment of the integration of a unitary Judicial Power in the model of an Autonomous State or of the Autonomies. Coordination between Titles VI and VIII has never been without its problems. The object of this paper is a brief analysis of the constitutional framework of the Judiciary and the pertinent clarification regarding the principle of jurisdictional unity, which -contrary to what we sometimes see reflected in opinion articles- is not directly related to the design of the State of the Autonomies, being another the problem of interest that the regional territorial model raises: the proper interpretation of the constitutional limitations affecting the concept of Administration of Justice.

Authors: Oyewola David , Dada Emmanuel
Published: March 2022

The global health crisis that started in December 2019 resulted in an outbreak of coronavirus named COVID-19. Scientists worldwide are working to demystify the transmission and pathogenic mechanisms of the deadly coronavirus. The World Health Organization has declared COVID-19 a pandemic in March 2020, which makes it essential to track and analyse the research state of COVID-19 for guidance on further research. This research was conducted using scientometric analysis, knowledge-mapping analysis, COVID-19 studies and journal classifications. The publications used in this study include over 3000 COVID-19 papers made available to the public from 1 January 2018 to 15 April 2021 in the PubMed databases. In this study, it was discovered that the rapid reaction of researchers worldwide resulted in a fast growth trend between 2019 and 2021 in the number of publications related to COVID-19. It was discovered that the largest number of studies is in the United States of America, which is one of the countries most affected by a pandemic. The method adopted for this study involved the use of documents such as Case Reports (CAT), Journal Article (JAT), letter (LTR), EAT, and Editorial (EDT). This is followed by the classification of COVID-19 related publications that were retrieved from PubMed between 2019 and 2021 using machine learning (ML) models such as Naïve Bayes (NB), Bayesian Generalized Linear Model (BGL), Heteroscedastic Discriminant Analysis (HDA) and Multivariate Adaptive Regression Spline (MAR). Simulation results show that the classification accuracy of MAR is better than that of other ML models used in this study. The sensitivity of the MAR is within the range of 100%. This shows that MAR performs better than NB, BGL and HDA. MAR performs better with an overall accuracy of 89.62%. Our results show a high degree of strong collaboration in coronavirus research and the exchange of knowledge in the global scientific community.

A review: Effect of silver nanoparticles on human health following various routes of administration
Authors: Chopra Aarti , Kumar Ravi , Kumar Gautam Girendra
Published: March 2022

Individuals are employing silver nanoparticles in a wide range of medications, scientific studies and medical devices, which necessitates more study in order to understand the long-term implications of exposure. It is not always possible to avoid exposure to silver nanoparticles if they are spread across a large area, such as an industrial site. Silver nanoparticles can be inhaled, ingested, or interact with the skin. People's health is impacted by several aspects, including how much exposure (how much), how long they have had it (how long it is been), what form of exposure they have used, what other chemicals present in the environment (such pesticides), and how healthy they are at the time of exposure. Toxicology following exposure to silver in a variety of ways necessitates additional investigation, even though several studies have already been published (AgNPs).

Antimicrobial agents are most commonly prescribed drug and share major cost of the treatment. In india, health insurance doesn’t cover all people leading to out-of-pocket expenditure.

To study the cost-effectiveness of Antimicrobial agents and to recommend the proper therapeutic strategy for the use antimicrobial agents.

The present cross sectioned study was carried out in by collecting data from admitted patient’s case paper, tabulated in seven groups of disease and four groups of antimicrobial agents, scrutinized for its pharmacoeconomics. Statistical analysis done by using Fisher’s Z- test.

Antimicrobials should be preferably prescribed after culture sensitivity test so as to avoid wastage of money spent on empirically prescribed non-sensitive antimicrobials. In the current study Staphylococci, E.coli then Klebsiella are found to be most commonly found organism in the samples, which can help as a guideline for prescribing antimicrobial therapy.

Published: March 2022

This narrative review focussed on Diabetes which has emerged as a significant public health problem after cardiovascular diseases and the sixth leading cause of mortality worldwide. India faces a massive burden of Diabetes, which parallels a similar rise in obesity and metabolic syndrome. (Diabetes mellitus currently had a global prevalence of 6.4%, aged 20-79 years in 2010). Diabetes prevalence among adults over 18 years has increased from 4.7%in 1980 to 8.5 % in 2014 (WHO) and is estimated to be 10.2% by 2030 (IDF). India has the second-largest number of diabetics (about a 61million, i.e., the prevalence of 8.8% and about 77 million, i.e., majority of 8.9%).The number is likely to increase to 101 million (prevalence of 9.9%) by 2030. These rising figures are primarily due to marked transitions leading to unhealthy diets and physical inactivity. That causes problems like retinopathy, cardiomyopathy, nephropathy, and neurodegenerative diseases. Diabetes is the most common progressive heterogeneous endocrine disorder with devastating multi-systemic complications characterized by altered glucose homeostasis and insulin resistance. Diabetes is principally divided into two types Diabetes Insipidus and Diabetes Mellitus (DM). Again, DM is of 2 types — Type 1(Juvenile/Insulin-dependent) and Type-2 (Insulin resistance). Type1-DM is prevalent in the young population, associated with a lack of insulin production due to auto-immune destruction of beta cells of the pancreas. In contrast, Type2-DM is due to the inability of cells/tissues to respond to insulin appropriately. Long-term chronic hyperglycemia leads to organ dysfunction leads to organ failure, especially kidney, eyes, heart, and blood vessels.

This paper presents a novel and efficient optimization approach based on the Artificial Ecosystem Optimization (AEO) algorithm to solve the problem of finding optimal location and sizing of Distributed Generation (DGs) in radial distribution systems. The objective is to satisfy a fluctuating demand in a constant and instantaneous way while respecting the requirements of power loss reduction, operating cost minimization and voltage profile improvement within the equality and inequality constraints. The robustness of the proposed technique in terms of solution quality and convergence characteristics is evaluated using the IEEE-33 bus radial distribution network test system. The simulation results are compared with those of other methods recently used in the literature for the same test system. The experimental outcomes show that the proposed AEO approach is comparatively able to achieve a higher quality solution within a timeliness of computation.

For decades, scholars have debated which mode of education is superior amongst online versus traditional teaching. Some argue in favour of traditional or face to face teaching and others consider online teaching better. Still others suggested hybrid or blended mode of teaching as the most effective and productive method. This shift in strategy for medical education delivery has been driven by external forces beyond the influence of the institutions as well as by their internal dynamic. However, students’ perception towards online teaching as compared to traditional teaching has largely been overlooked. Aims and Objectives: This study or survey in covid pandemic intends to fill this void in the literature, and explore medical students’ perception and obtain their feedback towards online learning or teaching versus traditional teaching (face to face) mode of education in the medical field. Material and Method: Present survey included 1100 medical students from different medical colleges situated under different universities in North India. Survey was developed, which included a total of 14 questions (5 were demographical). After obtaining their responses, statistical analysis of responses was done. Conclusion: The results of present study concluded that medical students preferred traditional teaching over online mode of teaching.

A Study of Etiology, Clinical Profile and Outcome of Patients Presenting with Acute Urinary Retention to a Tertiary Care Hospital
Authors: Bhamre Sudhir , Verma Deepa
Published: March 2022

Introduction: Acute urinary retention (AUR) is defined as the sudden inability to pass urine even with a distended bladder. A population-based study reported the incidence AUR of 2.2 to 6.8 per 1000 men per year. One in 10 men over the age of 70 may experience AUR within 5 years. In contrast, AUR is rare in women. Definitive management of AUR depends on the precipitating cause which can be medical or surgical. Immediate treatment of AUR is to drain the urinary bladder either by urethral catheterization or by a suprapubic cystostomy. Prospective studies on AUR are few in India, and very less is known regarding its prevalence. In view of this, there is a need to formulate a baseline data in the area of acute urinary retention. Aims and Objectives: 1. To study etiology of Acute Urinary Retention in patients presenting at Tertiary Care Hospital. 2. To study the clinical profile of patients presenting with Acute Urinary Retention to a Tertiary Care Hospital. Material and Methods: It is a Prospective Observational Study conducted on patients visiting the Emergency department, OPD and/or cases admitted in the IPD for Acute Urinary Retention in the department of General Surgery at Tertiary Care Hospital. Relevant history was taken and detailed clinical examination along with appropriate investigation including ultrasonography, etc. were carried out in all cases. Appropriate medical (including medication, urethral catherization or suprapubic catherization) or surgical treatment (like surgeries for urethral stricture, phimosis, urethral calculus etc.) was given to the patient as per standard hospital protocols. Results: Mean Age of the study group was 61.54 years with majority of the patients 68% were more than 60 years of age. Male preponderance was observed in the study group with prevalence ratio of 48 (96%) males to only 2 (4%) females. Most common etiology of acute urinary retention was benign prostate hyperplasia (44%) followed by urethral stricture (26%), carcinoma prostate (6%), phimosis (6%) and bladder neck calculi (4%). Foley's catheterization was done in 41 cases (82%) while supra-pubic catheterization was done in 9 cases (18%) cases. Out of the 36 cases in which trial without catheterization was attempted, 32 were successful. Out of the 45 cases with surgical management, TURP was done in 22 cases while Urethrotomy and Cystolithotrypsy was done in 12 and 4 cases. TURP + bilateral orchidectomy and circumcision was done in 3 and 2 cases respectively. Conclusion: The most common age for presentation with Acute Urinary Retention is 51-70 years and with male predominance. In our study we can conclude that the most common etiology for AUR is Benign Prostatic Hyperplasia followed by Urethral Stricture, Carcinoma of Prostate and Phimosis. The primary management to relieve the retention in an emergency situation is mainly by urethral catheterization failing which Suprapubic catheterization is done but definitive management for AUR is surgical.
