Janus Kinase Inhibitors in the Treatment of Alopecia Areata
Authors: Stefanis Athanasios J.
Published: February 2023

Alopecia areata is a disease of autoimmune origin which causes non scarring hair loss. The extent of alopecia varies from a small patch to complete scalp and body hair loss, which can have huge psychosocial impact for those affected. Treatment modalities which have been used so far included nonspecific immunosuppressive medications, such as corticosteroids, cyclosporine, and methotrexate, or topical immunomodulators, such as diphencyprone, dithranol, and squaric acid dibutylester. The recognition of the importance of Janus kinase pathway in alopecia areata pathogenesis enabled more specific approaches in treatment. Positive outcomes of Janus kinase inhibitors in several trials granted approval for baricitinib which became the first on-label treatment for alopecia areata. The aim of this review is to summarize the role, efficacy and safety of several Janus kinase inhibitors in alopecia areata.
Screening for SARS-COV-2 Using RT-qPCR in Patients with Hematologic Neoplasms Receiving Chemotherapy
Authors: Santarelli Ignacio Martín , Sierra Mariela , Fernández Sofía Isabel
Published: February 2023

It has been recommended that patients with leukaemias and lymphomas undergo universal screening for SARS-COV-2 using RT-qPCR before each treatment on the grounds of their high risk of experiencing severe forms of COVID-19. This raises a conflict with different recommendations which prioritise testing symptomatic patients. We found that among 56 RT-qPCR obtained in asymptomatic patients with hematologic neoplasms before chemotherapy administration, 2 (3.5%) were positive. A negative result did not exclude SARS-COV-2 infection in 1 patient (1.8%). It is unclear what the benefit of screening for SARS-COV-2 using RT-qPCR in patients with hematologic neoplasms who receive chemotherapy is.

Egzystencjalny i religijny wymiar speleologii w twórczości Wojciecha Kuczoka
Authors: Jujka Zuzanna
Published: February 2023

Artykuł stanowi próbę przeanalizowania religijnej i egzystencjalnej funkcji przyrody w prozie Wojciecha Kuczoka. Wielokrotnie przez pisarza podkreślana przed-człowieczość jaskiń, budzący grozę majestat górskich szczytów, obcowanie z formacjami powstałymi przed milionami lat – wszystko to „wywołuje metafizyczny dreszcz”, prowadzi do nadania naturze wymiaru sakralnego. Przekształceniu i przewartościowaniu ulega pojęcie czasu, żywot ludzki zdaje się być zaledwie mgnieniem w obliczu odwieczności świata przyrody. Dlatego też w pisarstwie Kuczoka prawdziwymi świątyniami okazują się nie wznoszone ludzką ręką kościoły czy katedry, a jaskinie i groty – tylko w owych „cudach odwiecznych” poszukiwać można „śladów Boga”
Interkomprehensja – interferencja – integracja. Polszczyzna w perspektywie nauczania użytkowników języków wschodniosłowiańskich
Authors: Hofmański Wojciech , Pospiszil-Hofmańska Karolina
Published: February 2023

The paper is an introduction to teaching the Polish language and culture to native users of closely related languages. The presented synthesis is intended for teachers interested in improving their competence in teaching Polish to East Slavs and those who have just started their adventure in Slavic glottodidactics. The paper grew out of a desire to make teaching Polish to East Slavs (mainly Ukrainans) as effective as possible due to the rapidly increasing need because of a large number of war refugees from Ukraine. Based on their experience in teaching Polish to native users of East Slavic languages, the authors pay particular attention to the Slavic intercomprehension phenomenon and its influence on the glottodidactic process. They also address the problem of the key grammatical mismatches and introduce several good practices.
Kilka uwag o współczesnej kynonimii zachodniosłowiańskiej
Authors: Kołodziej Agnieszka
Published: February 2023

This article investigates kynonyms, which constitute one of the most prominent categories of zoonyms. The research material was obtained with the use of an 11-point survey and encompasses the West-Slavic languages: Polish, Czech and Slovak. The study aims to indicate the core tendencies in how dogs are named in these languages, as well as potential regularities or inconsistencies therein. The article encompasses a theoretical component, a discussion on terminology and an exploration of the research material (through semantic and formal means). Most kynonyms are created through the use of: names or surnames of fictional characters known from television and films; pragmatic names; and a characteristic of the animal itself. Only approximately 6.5% of the researchmaterial includes the names derived through word formation; the other names involve metaphorical references. The study also incorporates a stratification of the dog’s image; however, the only correlation uncovered was the relationship between the race of the dog (small or large) and the type of accommodation in which that dog stayed.

Константин-Кирил (Vita Constantini: who, when, where) by Maya Ivanova and Tsvetomira Danova, published in 2021 in Sofia. The book consists of two main parts. The first and most extensive part is a kind of lexicon with 177 entries: personal name and by-names of actual historical figures; biblical and mythological characters; names of ethnonyms, tribes and languages; geographic names (including names of sacred objects), difficult and archaic words. Part II contains the text of the Vita. The book is a handbook intended for a wide groupof lay audiences, including Bulgarian Studies scholars abroad. This handbook is a coherent and well-thought-out entity. The study combines the condition of scientific credibility with the feature of accessibility. There is a need for similar teaching aids in the didactic process of students of Slavic studies.
The Double Life of a Packet of Sugar. The Noise(lessness) of Communication of the Items of Everyday Use
Authors: Kołodziej Agnieszka
Published: February 2023

This review discusses the book by Aleksander W. Mikołajczak and Patryk Borowiak entitled Design saszetki zcukrem. O komunikowaniu się zrzeczami (On the Design of a Packet of Sugar. How WeCommunicate with Objects). The text focuses on theinteractions between people and objects, a phenomenon intrinsic to postmodernity, or the contemporary consumerist culture. The work is a peculiar biography of the packet of sugar and presents a multifaceted exploration thereof. The authors depart from the commonly conducted statistical analysis of the object of interest and instead endeavour to present the full extent of its existence and all the subsequent stages of its life, pointing to the complexity and the volatility of the process; this should be considered an innovative approach at its own right. The packet of sugar is viewed not only in the sociocultural perspective, but also through the lens of linguistics and onomastics.
The Image of China in Milan Jovanović’s Tamo amo po istoku
Authors: Yuchao Peng
Published: February 2023

Serbian traveler Milan Jovanović arrived in China in the 19th century, and after his return, his travelogue Tamo amo po istoku (Here and There in the East) was published. This article aims to reveal Jovanović’s perception of China in his writings, in order to analyze the image of China and more importantly, his dilemmas of self–positioning while facing the East and the West. By applying comparative literary imagery theory and cross–cultural methods, this paper interprets the literal value of Jovanović’s work, and discusses the interactions between the East and the West, as well as the “self” and the “others.” This article argues thatJovanović’s self–affirmation is faced with two “others”: the heterogenous “other” of Eurocentrism, and the homogenous “other” of Eastern utopia. His image of China is constructed in the tension between the two.
Effect of post-weld heat treatment on 6156 aluminum alloy joint formed by electron beam welding
Authors: Wang Shaogang , Xu Junke , Wang Yongpeng
Published: February 2023

The 6156 aluminum alloy is welded by electron beam welding, and different post-weld heat treatments (PWHTs) are carried out on the joints. The microstructure, mechanical property, and corrosion behavior of the welded joint before and after PWHT are investigated, respectively. Results show that the fusion zone is composed of columnar crystal and equiaxed grain in as-welded (AW) condition. There are mainly α-Al matrix phase, and some strengthening phases β″(Mg2Si) and Q(Al4CuMg5Si4) in weld metal. After PWHT, the quantity of strengthening phases in weldment is greatly increased, and their distribution is also improved. The tensile strength of welded joint is 65.8% of that of the base metal (BM) in AW condition. After the heat treatment of HT2, the strength coefficient of joint reaches 85.1%. There are many dimples on the tensile fracture surface, and the joint obviously presents the characteristic of ductile fracture. The electrochemical corrosion performance and resistance to intergranular corrosion of weldment in AW condition are higher than that of the BM. However, they are decreased to a certain extent after PWHT. Compared with that of the AW joint, the resistance to intergranular corrosion is slightly decreased after PWHT, and that of the HT2 joint is the best among them.
Priscian’s Latin: new insights from the manuscript tradition
Authors: Spangenberg Yanes Elena
Published: February 2023

The paper deals with a selection of linguistic features of Priscian’s Latin (6th century AD), namely the use of the indefinite pronoun and adjective after a negation, the declension of Greek loan-words with nominative ending in -ys, and the use of verbal moods and tenses in concessive clauses. The inquiry takes advantage of the new ongoing collation of the 8th–10th-century manuscripts of the Ars Prisciani, which enables ascription to Priscian’s linguistic use of some peculiar syntactic and morphological features that had been obliterated by the standardizing attitude of the former critical editor, Martin Hertz.
Consonant epenthesis in Latin
Authors: Oniga Renato , Re Alessandro
Published: February 2023

This paper intends to focus on two aspects: how the Latin grammarians developed the concept of epenthesis, and how we can now give an explanation to this phenomenon. After having gathered the phonological evidence from the tradition of Latin philology, we propose that, in prehistoric Latin, the epenthesis of -t- in the -s.r- cluster, and the epenthesis of -p- in the -m.l- cluster, aimed at solving some problems in syllabification, that is avoiding an illicit syllable onset and an illicit coda-onset sequence, respectively. We then observe that, in classical Latin, the only productive process is the epenthesis of -p- in the -m.s- and -m.t- clusters, which has the function of fulfilling the faithfulness constraint on the inflection of the -m- stems, blocking the m > n assimilation process that later took place in the evolution from Latin to Italian.
Person-centered language and pediatric ADHD research: a cross-sectional examination of stigmatizing language within medical literature
Authors: Robling Kristyn , Cosby Caitlin , Parent Gunner , Gajjar Swapnil , Chesher Tessa , Baxter Michael , Hartwell Micah
Published: February 2023

Context

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children and often goes untreated. A major barrier to treatment is the stigma surrounding the disorder, including from the educational and scientific community. Person-centered language (PCL) is associated with positive health outcomes, and its implementation is recommended by multiple professional groups, but its use has not been quantified for ADHD.

Objectives

The goal of this study is to quantify the adherence to PCL among ADHD-related journal publications utilizing a cross-sectional study design.

Methods

We conducted a cross-sectional examination including a systematic search of PubMed, which encompasses MEDLINE, for ADHD-related articles from January 2014 to March 2021. All journals with at least 20 ADHD-related search returns, human research, and in the English language were included, totaling 5,308 articles from 88 journals. Articles were randomized, and the first 500 were screened for inclusion of prespecified, non-PCL terminology. After exclusion, 311 articles were retained.

Results

Of the 311 retained articles, 131 (42.1%) adhered to PCL guidelines. Among articles with non-PCL, stigmatizing language such as “problem(s) with [the/a] child or problem child” and “suffers from” was found most frequently— occurring in 47.6% (148/311) and 5.8% (18/311) of the articles, respectively. We found no significant association between PCL adherence and study characteristics.

Conclusions

Our findings revealed that over half of the current ADHD literature did not adhere to PCL guidelines. Adherence to PCL by the scientific and medical community will increase the overall efforts to mitigate stigma and increase support for individuals with ADHD.
A dual role of proton pump inhibition on cancer: a critical review
Authors: Edizer Deniz Tuna , Akcali Zeynep , Leblebici Asım , Korkut Sıla Övgü , Ellidokuz Ender
Published: February 2023

Proton pump inhibitors (PPIs) are widely used to suppress gastric acid secretion. Proton pumps belong to the family of ATPase and among them P-ATPase and V-ATPase types regulate intracellular as well as extracellular acid equilibrium. The main aim of the current survey is to present the existing literature putting forth the relation between cancer with both the use of PPIs and proton pumps from positive and negative aspects. To perform an objective study, various types of proton pumps and their relation to cancer have been taken into account. Up to date, the studies have been considered in the time range from 2011 to 2021 via various databases (PubMed, Scopus, and Google Scholar). H+/K+ ATPase, located within the gastric parietal cells, is one of the most important examples of P-ATPases. The findings of the literature review along with criticism were presented as decreased P-ATPase expression can be used as a marker for gastric cancer diagnosis whereas the association of the proton pump with cancer may be mainly due to V-ATPase. In conclusion, molecular, epidemiological, and bioinformatic studies are required to enlighten the subject.
More than words: Eine mehrsprachigkeitsorientierte Perspektive auf die Dilemmata von Street-level Bureaucrats in der Klient*innenkommunikation
Authors: Holzinger Clara , Draxl Anna-Katharina
Published: February 2023

In „super-diversen“ Migrationsgesellschaften ist die Frage nach dem Umgang mit Pluralität entscheidend und folgenreich für soziale Gerechtigkeit. Insbesondere sprachliche Diversität stellt für öffentliche Organisationen, die in einem Spannungsfeld zwischen gesellschaftlicher Mehrsprachigkeit und monolingualer Orientierung agieren, eine Herausforderung dar. Ausgehend von der Annahme, dass Sprache neben der mittelnden stets auch eine soziale Funktion hat, analysiert der vorliegende Beitrag, wie sprachliche Pluralität auf der Beziehungsebene die professionelle Interaktion zwischen Street-level Bureaucrats und Klient*innen prägt. Die Daten stammen aus dem qualitativen Forschungsprojekt AMIGS, das den Umgang mit sprachlicher Diversität am österreichischen Arbeitsmarktservice untersucht. Die Analysen zeigen, dass die Beziehungsarbeit mit Herausforderungen und Paradoxien verbunden ist, welche im Kontext migrationsgesellschaftlicher Mehrsprachigkeit verschärft auftreten können und zusätzliche Dimensionen aufweisen.

The Human Gut Game
Authors: Yam Kylee
Published: February 2023

The human gut microbiome is an important part of the digestive system and the human body as a whole. The abundance and richness of bacterial species in your digestive tract change based on your diet and lifestyle. A diet full of fresh vegetables, meat, and whole grains will cultivate a variety of bacteria that will help you absorb nutrients, prevent disease, keep your skin hydrated, and even improve cognitive function. A diet of sugar- and fat-rich foods will cultivate less diverse bacteria and species that cause inflammation in your gut and impair memory and focus (Quercia et al., 2014). I designed a simulation that uses inquiry and game play to teach high school (grades 9–12) biology students these concepts. The game involves teamwork, decisions about diet, cause and effect of various life events, and data analysis. Educational approaches such as game play and active learning have been shown to improve student engagement, retention of concepts, and overall success of a lesson (Sengupta and Clark, 2016; Michael, 2006).
Teaching Evolution Using Semester-Long Student Investigations of Adaptation by Natural Selection
Authors: Haenel Gregory
Published: February 2023

Case studies are valuable tools for instruction but are often limited to a single topic and a single class period. Courses such as evolution that synthesize multiple concepts around a common theme, however, can use a single case study type project that extends over the entire semester to develop and link core concepts. A central theme in evolutionary biology is determining if complex biological traits represent adaptations that arose by natural selection. The instructional model presented here engages students in a step-by-step process to answer this question of adaptation for a trait of their choosing. In this process, the instructor first introduces the major concepts required to address adaptation. As each major concept is developed in class, students apply this concept to their particular trait, using information gathered from published studies. Students then report their research back to the class. At the end of the semester, each group synthesizes their evidence into a paper developing an argument as to whether or not their trait fits the criteria of being an adaptation. This project provides students with ownership of course material, gets students to act as practicing scientists, and helps them integrate and apply theoretical material to real questions.
Sexual Selection as a Tool to Improve Student Reasoning of Evolution
Authors: Spier Sarah K. , Dauer Joseph T.
Published: February 2023

There is an emphasis on survival-based selection in biology education that can allow students to neglect other important evolutionary components, such as sexual selection, reproduction, and inheritance. Student understanding of the role of reproduction in evolution is as important as student understanding of the role of survival. Limiting instruction to survival-based scenarios (e.g., effect of food on Galapagos finch beak shape) may not provide students with enough context to guide them to complete evolutionary reasoning. Different selection forces can work in concert or oppose one another, and sexual selection can lead to the selection of trait variants that are maladaptive for survival. In semistructured interviews with undergraduate biology students (n = 12), we explored how leading students through a sequence of examples affected student reasoning of evolution. When presented with an example where sexual selection and survivability favored the same variant of a trait, students emphasized survival in their reasoning. When presented with a scenario where sexual selection selected for trait variants that were maladaptive for survival, more students described how two different selection forces contributed to evolutionary outcomes and described reproductive potential as a part of fitness. Moreover, these students considered how the maladaptive traits were inherited in the population. Scenarios where sexual selection and survival-based selection were opposed improved student ability to reason about how factors other than survival impact evolutionary change. When instructors introduce students to scenarios where survival-based selection and sexual selection are opposed, they allow students to change their reasoning toward inclusion of reproduction in their evolutionary reasoning.

Published: February 2023

The success of dental implants is influenced by several biomechanical factors such as implant design, bone quality, length of the implant, and the load transferred to the implant. The present studyaimsto determine the effects of bone quality, implant length, and bone type on stress/strain distribution in bone and implant for a zirconia implant. The study was performed using the three dimensional finite element analysis and four different lengths, two types of implants, and four different bone qualities. The Elastic modulus of a cancellous bone was varied to represent the four different bone qualities. A load of 100 N was applied at the center of the abutment. The result of this current work shows that a bone is subjected to the maximum equivalent stress and strain when the cancellous bone density decreased. The screw type implant induced lesser strain than the cylinder type load. The study also confirms that longer implants produced lesser stain than shorter implants, and type I, and II bones induced lesser stresses than type III, and IV bones. The importance of bone quality has been confirmed from this study, and zirconia dental implants have induced lesser stresses.

Published: February 2023

The suitability of agricultural soil and irrigation water depends on the presence of trace metals; the aim of the present work is to assessment of the trace metals at Hail region using analytical techniques. The metal contaminations levels were determined using ICP-MS and flame photometer. The result obtained were compared to the standard samples suitable for agricultural and it was in the suitable range. The geo-accumulation (I-geo), single pollution, Nemerow pollution indices showed that the Se pollution intensity was significant for agricultural soils. I-geo values revealed no real sign of contamination with almost all the samples, reflecting a lack of contamination for all elements except Zn. While the enrichment factor (EF) for Fe was less than 2 suggested that the elements come entirely from crustal materials or natural processes. The study showed considerable variation in the levels of the analyzed elements in the soil samples. The total metal concentrations in the soil samples ordered as follows: Na > K > Fe > Mn > Zn > Ba > Cr > Ni > Cu > Pb > Cd > As.

Plant-mediated synthesis of ZnO nanoparticles (ZnONPs) is preferable than the conventional methods with many applications in medicine and biology. Artemisia annua is recognized to have antiplasmodial, antimicrobial activities, so the nanoformulation based on its extracts and zinc oxide would be of therapeutic benefit. This study aims to investigate properties of ZnONPs based on Artemisia annua leaves and stems extracts and zinc acetate. Spectroscopy techniques, XRD, SEM and Energy Dispersive X-ray Spectroscopy (EDS) were used to investigate the structural and optical properties of the ZnONPs. The characteristic absorption peak was at 375.5 nm and the excitation at 365 nm showed wide spectra in visible (450-700 nm). XRD, SEM and EDS analysis confirmed a pure ZnONPs in wurtzite hexagonal structure with a size of 21.34 - 24.71 nm.

O objetivo principal deste estudo foi analisar a percepção de acadêmicos do Curso de Enfermagem sobre o processo de envelhecimento, refletindo sua contribuição na reformulação de currículos que contextualizam a saúde do idoso. Os dados foram coletados em duas instituições de ensino superior de Enfermagem, no período de agosto de 2009 a julho de 2010, com a participação de 84 acadêmicos. Por meio da análise do conteúdo, foram elencadas três categorias temáticas: o processo de envelhecimento se refere ao estágio vital de fragilidade e necessidades de cuidados especiais; o envelhecimento é um processo natural do ciclo vital; o processo de envelhecimento é uma fase que requer mais atenção social. Os resultados demonstram que há necessidade de se planejarem ações de ensino, pesquisa e extensão, dentro do enfoque da gerontologia, para romper com os tabus em torno da velhice e enfocar o tão almejado envelhecimento saudável.

O presente estudo tem como objetivo avaliar a implementação do quarto passo para a promoção do aleitamento materno em um hospital amigo da criança em Recife-PE, Brasil. Trata-se de um estudo descritivo, observacional, transversal, quantitativo. A amostra correspondeu a 80 profissionais de saúde, sendo 47 médicos e 33 da equipe de enfermagem. Os dados coletados oriundos de entrevista e observação não participativa foram analisados pelo programa Epi-Info versão 6.04, sendo realizada análise descritiva e bivariada, utilizando-se o teste qui-quadrado, considerando nível de significância de 5%. Apenas 36,6% dos recém-nascidos foram contemplados com o 4º passo. Entre aqueles com Apgar ≥ 6 no 1º minuto, 59,3% não foram colocados no peito e nem ficaram em contato pele a pele com sua mãe. O parto transvaginal foi estatisticamente mais significante em comparação ao cesáreo. O hospital em estudo não está implementando como rotina o 4º passo para a promoção do aleitamento materno.

Published: February 2023

Este estudo objetivou identificar o entendimento de enfermeiros de um pronto-socorro acerca da humanização e sua concepção sobre o acolhimento com classificação de risco. Pesquisa qualitativa, descritiva, realizada de julho a setembro de 2010 por entrevista semi estrututrada com oito enfermeiros de um pronto-socorro de um hospital-escola em Curitiba-PR. Os dados foram submetidos à análise de conteúdo de Bardin. Emergiram três categorias: a primeira descreve o entendimento dos enfermeiros do pronto-socorro acerca da humanização; na segunda, evidencia-se o entendimento desses enfermeiros acerca do acolhimento com classificação de risco; e na terceira são elencados os elementos essenciais à implantação do acolhimento com classificação de risco. Há necessidade de os sujeitos se aprofundarem nas preconizações da Política Nacional de Humanização para a implantação do acolhimento com classificação de risco nesse cenário.

A gravidez na adolescência constitui grave problema social e de saúde pública, pelas consequências à mãe e ao concepto. Estudo qualitativo que objetivou apreender o significado da gravidez na adolescência para os familiares. Foi desenvolvido com sete familiares de adolescentes grávidas e/ou que tiveram o parto no ano de 2010, assistidas em um Centro de Saúde da Família de Fortaleza – CE, Brasil. As informações foram buscadas num roteiro de entrevista semiestruturada, realizada nos domicílios dos familiares. Os resultados foram organizados em temáticas e analisados de acordo com a literatura pertinente. Detectaram-se variadas manifestações de sentimentos e reações ocasionadas pela singularidade da história, dinâmica familiar, contexto sociocultural e econômico vivido pela família. Diversas causas contribuíram para a gravidez precoce, sendo necessária uma abordagem ampla dos profissionais de saúde, familiares, comunidade e governantes, como também a inclusão de familiares ou de pessoas significativas numa assistência pré-natal holística e humanizada.

Modeling and Control of Small-Scale Underground Mine Ventilation Networks
Authors: Rodriguez Diaz Oscar Oswaldo , Franco-Mejía Edinson , Rosero Esteban
Published: February 2023

This paper presents a nonlinear model and a control strategy to regulate airflow in small-scale underground mine ventilation networks. In underground ventilation control systems, a sensor and an actuator for each branch are usually considered. However, in small-scale underground mines, it is too expensive to have automatic doors for controlling the air flow in each tunnel, as well as to install flow and gas sensors in each branch. In order to regulate airflow in small-scale underground ventilation networks, the number of sensors and actuators is regarded as a limitation for practical installation. This work presents an alternative modeling of the network, with direct control of the airflow in each tunnel, by varying the speed of the fans available on the external surface of the mine. A state space model is presented, and a linear quadratic controller with integral action and a state estimator is designed. To validate the model and the controller, a network ventilation system for a small-scale mine with nine branches (tunnels) and two actuators (fans) is presented.

Published: February 2023

It is a customary practice to carry out standardless elemental microanalysis by energy dispersive spectroscopy (EDS) under the very same operational conditions as those used for scanning electron microscope (SEM) imaging. In this article, EDS experiments were carried out with stainless steel (SS), varying the EDS testing operating conditions. The results showed that, if X-ray spectra are acquired under operating conditions that are very dissimilar to those optimized for microanalysis, both the detectability limit of minor species (Si, Mo, and Mn) and the uncertainty in the concentration of major alloying elements (Cr and Ni) are noticeably impaired. It was observed that, by improving the signal-to-noise (S-to-N) ratio (i.e., by increasing the accelerating voltage, beam intensity, and total acquisition time, or when the working distance is optimized), the precision of the elemental concentration increases, but the accuracy is only marginally affected. For the major alloying elements, 25% of the measurements showed a percent discrepancy higher than three times the standard deviation, which is inconsistent with a normal statistical distribution.
Entropy and coefficient of variation (CV) as tools for assessing power quality

Published: February 2023

This paper presents several concepts and techniques for quantifying electric signal entropy and variability for assessing power quality, showing their irregularities, such as the electrical sine wave which delivers power to industry and homes. The paper will review these concepts and show some magnetic radiated waves measurements taken below 115 KV electricity line circuits in the city of Manizales (Colombia) through non-invasive and indirect measurement of the complexity of the current transported by the supply.
Entropy, as an accepted indicator of physical complexity, is proportional to the logarithm of the number of states in a thermodynamic system. Some writers have identified entropy as being system disorder, but this is not completely true. Entropy of information was first defined by Shannon in 1949 and it is applied to many physical events. Entropy has been used for describing the complexity of the magnetic wave radiated by the line in this paper. Furthermore, the magnetic waves' spectral and amplitude coefficient of variation (CV) were obtained using a multi-resolution wavelet algorithm which measures data distribution dispersion. It is a dimensionless number allowing the variation of magnetic radiated data having significantly different mean values to be compared to a 60 Hz pure magnetic wave as reference.
