Published: September 2024

Abstract The blue palm (Bismarckia nobilis) is one of the most used ornamental palms in landscaping, due to its size and slightly bluish fan-shaped leaves. However, its propagation is carried out through seeds and the germination of these seeds is extremely low, in addition to the plant growth being considered slow. This work aimed to compare the use of pre-germination treatments to break dormancy and accelerate germination of B. nobilis seeds. The effect of mechanical scarification (sanding the region opposite the embryonic axis), thermal (immersion in water at 40 ºC, 60 ºC and 80 ºC for 5 min) and chemical (immersion in sulfuric acid 98% for 15; 30; 45 and 60 min), as well as its imbibition in solutions containing GA3 (gibberellic acid) at concentrations of 250; 500; 750 and 1000 mg L-1 on germination and speed of germination of seeds of the species. The results showed that the pre-germination treatments of mechanical and thermal scarification presented the best results compared to the other treatments.

Published: September 2024

Abstract Golden-Dewdrop (Duranta erecta L.), known for its landscaping applications, undergoes successive pruning to maintain its ornamental structure, a practice known to induce numerous physiological and chemical responses in the plant. Therefore, this study aimed to evaluate the influence of pruning and different extraction methods on the allelopathic potential of Golden-Dewdrop on the germination and initial growth of lettuce. Leaf extracts were obtained by decoction (hot) and maceration (cold) at concentrations of 20%, 40%, 60%, 80%, and 100%, with distilled water as a negative control. Phytochemical screening of the extracts was performed for phenolic compounds, flavonoids, anthocyanidins, tannins, cardioactive heterosides, saponins, alkaloids, and terpenes. For the bioassay, germinative and morphological parameters were measured and characterized. The data were subjected to analysis of variance (ANOVA), and for quantitative data, regression models were adjusted, while for qualitative data, means were compared using the Scott-Knott test with 5% significance. Significant differences were observed between extraction methods and management practices, with the hot aqueous extract from pruned plants significantly reducing germination at higher concentrations. The initial growth of lettuce was severely affected, presenting numerous morphological abnormalities, with severe damage to the root system at all concentrations. This study suggests that pruning practices have a modulating effect on the allelopathic activity of Golden-Dewdrop, providing valuable information for landscaping projects and botanical studies considering its evaluation and production of phytotoxic phytochemicals.

Published: September 2024

Abstract Alkaline stress is a major environmental factor that limits the growth and productivity of rose plants. Humic acid (HA) is a natural substance that has been shown to have various beneficial effects on plant growth and stress tolerance. Roses (Rosa hybrida L.) are among the world's most important and popular cut flowers, dominating the cut flower export market. This study investigated the effects of HA application on the physiological and biochemical properties of rose plants grown under alkaline conditions. A randomized complete design with three replicates was used. Each replicate consisted of two pots containing a single rose plant. Humic acid was applied at 0, 500, 1,000, and 2,000 mg L-1 through drenching at 15-day intervals for two months. Plants treated with 1,000 mg L-1 HA exhibited significantly higher levels of total protein, proline, catalase activity, guaiacol peroxidase activity, and antioxidant capacity. Control plants (receiving no HA) showed the highest levels of malondialdehyde and electrolyte leakage, indicating greater cellular damage. Plants treated with 500 mg L-1 HA displayed the highest sugar content and ascorbate peroxidase activity. Overall, the results of this study suggest that HA application can be an effective strategy to improve the tolerance of rose plants to alkaline stress and enhance their growth and productivity in alkaline soils.

Resumen Introducción La primera infancia es una etapa crucial para el desarrollo humano, donde el ambiente ejerce una influencia significativa en la formación y funcionamiento cerebral. La presencia de experiencias adversas puede desencadenar estrés tóxico, lo que a su vez puede obstaculizar de los hitos propios del desarrollo infantil. Objetivo El presente estudio tiene como objetivo describir las principales experiencias adversas en la infancia que provocan estrés tóxico en niños y niñas de 0 a 6 años, considerando también sus implicancias en la salud mental y el desempeño ocupacional. Método Se realizó una revisión narrativa utilizando bases de datos como Web of Science, EBSCO, Scopus y Psychology Database. Se seleccionaron diez artículos relevantes para el análisis. Resultados La búsqueda reveló que la pobreza, la violencia infantil y la discriminación, son las tres experiencias adversas más comunes que generan estrés tóxico. Además, se identificaron factores protectores que pueden mitigar el impacto de estas experiencias adversas, fortaleciendo la resiliencia infantil. Entre estos factores las características positivas de la crianza destacan como el principal elemento protector. Conclusión Aunque no se encontró una relación directa entre el estrés tóxico y el desempeño ocupacional en la literatura revisada, se concluye que este último se ve afectado indirectamente debido a su conexión con la salud mental y el desarrollo infantil, aspectos relevantes de la participación en actividades de la vida diaria. Lo anterior destaca la importancia de ampliar la investigación en el campo de la terapia ocupacional, ya que puede contribuir significativamente a la promoción y prevención de la salud mental en la infancia.

IMPACT OF NUTRITIONAL SUPPLEMENTATION ON ENVIRONMENTAL ENTERIC DYSFUNCTION (EED) IN CHILDREN LIVING IN RURAL AREAS: A SYSTEMATIC REVIEW
Authors: RACHMADI Rizky Abi , ARIANI Yulia , ALATAS Fatima Safira
Published: September 2024

ABSTRACT Background: A staggering 99% of infant undernutrition mortality comes from Sub-Saharan Africa and South Asia. Despite multiple interventions focusing on nutrition adequacy, 2.7 million children worldwide remain associated with undernutrition-related mortality. The lack of impact from multiple interventions toward undernutrition reflects a strong reason to believe that EED is the missing link that sustains undernutrition in low-to-middle-income countries (LMICs). EED is a sub-clinical condition caused by repeated oral enteropathogenic and non-pathogenic fecal microbes exposure that causes intestinal villous malformation, multi-omics changes, chronic intestinal and systemic inflammation, and gut dysbiosis. EED impacts the absorptive capacity and the integrity of the gut, causing a cycle of undernutrition in children. There is currently no protocol for the diagnosis and treatment of EED, hence EED is widely believed to be highly prevalent and underdiagnosed in LMICs. Objective: To our knowledge, this is the first systematic review to study the impact of nutritional interventions on EED. Previous studies yielded inconsistent results, hence the synthesis of this information is essential in attaining a deeper understanding of EED to formulate new targets of intervention against child undernutrition. Methods: This systematic review is registered to PROSPERO (CRD42022363157) in accordance to PRISMA, using keywords referring to nutrient supplementation, EED, and child growth failure. Results: Eleven articles were eligible for review, comprising randomized controlled trials performed mainly in the African continent, with a total of 5689 healthy children eligible for analysis. Conclusion: The systematic review illustrates that nutritional interventions have a minimal impact on EED biomarkers and linear growth and reflects the importance of understanding better the mechanisms causing EED and its consequences. It appears that the anabolic contribution of nutrition intervention to child growth is negated by EED.

ABSTRACT Sweet potato (Ipomoea batatas L.) have great genetic variability that contribute to higher production and root quality. Sweet potato farmers in the Western region of São Paulo state, Brazil, plant during the four seasons and have used the same genotypes for two decades. Thus, research is needed to evaluate new genotypes and indicate the most promising ones. Therefore, the objective of this study was to identify the adaptability and stability of sweet potato genotypes in six planting seasons: September 2019, January 2020, April 2020, September 2020, October 2020, and December 2020 in Western São Paulo using the linear regression methodology proposed by Eberhart & Russell (1966) and the centroid method. We evaluated 17 genotypes, two experimental genotypes from the germplasm bank of the University of Western São Paulo and two genotypes that have been cultivated for more than two decades by farmers (Canadense and Ligeirinha Paulista). The results show that Canadense, IAPAR 69, and SCS 272 Marina can be considered widely adapted in the Western region of São Paulo (favorable and unfavorable environments). In turn, the genotypes UBD 01 and UBD 02 are indicated exclusively for unfavorable environments, while Ligeirinha Paulista, INIA Arapey, SCS 369 Águas Negras, BRS Rubissol, Brazlândia Branca, Brazlândia Roxa, and BRS Amélia are indicated for favorable environments.

Published: September 2024

Abstract The objective of this work was to define experimental blocks for sugarcane experiments using geostatistical techniques, principal component analysis, and clustering techniques applied to soil properties. For this, data of soil chemical properties from a sugarcane experiment were used. Geostatistical techniques were applied to identify the spatial variability of these properties and to estimate the values for non-sampled locations through kriging. The principal components analysis was used for dimensional reduction, and, with the new variables obtained, the cluster analysis was performed using the k-means method to determine the experimental blocks with two to five replicates. Of the 12 analyzed variables, 10 showed spatial dependence. The principal component analysis allowed reducing the dimensionality of the data to two variables, which explained 82.27% of total variance. The obtained blocks presented irregular polygonal shapes, with different formats and sizes, and some of them showed discontinuities. The proposed methodology has the potential to identify more uniform areas in terms of soil chemical properties to allocate experimental blocks for sugarcane.

Authors: Ergin Malik , Koçkan Özgür
Published: September 2024

Abstract The objective of this work was to compare the performances of logistic regression and machine learning algorithms to predict infection caused by Fasciola hepatica in cattle. A dataset on 30,151 bovines from Uruguay was used. Logistic regression (LR) and the algorithms k-nearest neighbor (KNN), classification and regression trees (CART), and random forest (RF) were compared. The interquartile range (IQR) and z-score were used to improve the classification and compared to each another. Sex, age, carcass conformation score, fat score, productive purpose, and carcass weight were used as independent variables for all algorithms. Infection by F. hepática was used as a binary dependent variable. The accuracies of LR, KNN, CART, and RF were 0.61, 0.57, 0.57, and 0.58, respectively. The variable importance of LR showed that adult cattle tended to be infected by F. hepatica. All models showed low accuracy, but LR successfully distinguished variables related to F. hepatica. Both the IQR and z-score show similar results in improving the classification metrics for the used dataset. In the dataset, data related to climate or factors such as body weight can improve the reliability of the model in future studies.
FROM SOLIDARITY TO ENTREPRENEURIAL VALUES: THE NEOLIBERAL SHIFT IN THE ‘CENTER FOR EMPLOYMENT AND ENTREPRENEURSHIP SUPPORT’
Authors: Ulbricht Ferreira Gabriel
Published: September 2024

Drawing on ethnographic sociology, this paper presents the findings of a study conducted at the ‘Center for Employment and Entrepreneurship Support’ in São Paulo, Brazil. For over six months, several visits were made to this public institution in order to interview young workers. However, the word “Entrepreneurship” raised specific concerns: How does a public institution integrate São Paulo’s working class into the job market through entrepreneurial values? To address this issue, the study moves from the micro level of ethnographic observations to the macro level of external neoliberal forces that have shaped Brazil’s economic and political policies over the past decades. Furthermore, while the Center now promotes and even celebrates entrepreneurial values, the young workers' perceptions and experiences, as captured through qualitative interviews, reveal their reasons for seeking support from the institution and highlight how a reality shaped by informal labor challenges neoliberal approaches to public services.
O QUE TERIA WEBER A CONTRIBUIR A ANÁLISE DO CAPITALISMO CONTEMPORÂNEO?
Authors: Cartaxo Sintilla Abreu
Published: September 2024

O presente ensaio tem por objetivo destacar algumas das possíveis contribuições da perspectiva weberiana à análise do capitalismo contemporâneo. Para isso, apresenta um recorte da pesquisa de doutorado em fase inicial no PPGSP/UENF, que tem em vista compreender a formação e o processo de manutenção do conjunto de valores, princípios e normas que, na estrutura atual do capitalismo, vêm orientando vidas para o espírito empreendedor. A pesquisa vem utilizando as contribuições teóricas de Max Weber (2014) acerca do espírito e da forma do capitalismo como fio condutor da análise, por acreditar que, a partir desse núcleo é possível verificar como as estruturas sociais e as ações individuais interagem mutuamente, influenciando-se continuamente. A proposta de Weber, de dois lados, multinível e explicativa, permite ao pesquisador incorporar as complexas interações e dimensões interconectadas e multifacetadas do capitalismo contemporâneo. Em razão dessas características, a perspectiva weberiana oferece uma referência potente para pesquisas teóricas e empíricas que tratam da análise do capitalismo contemporâneo.
O relógio na cadeia anda em câmera lenta: interseções entre as categorias tempo e punição a partir da perspectiva de idosos encarcerados em uma penitenciária brasileira
Authors: Santana Filho Hosanah Pereira de
Published: September 2024

O trabalho tem por objetivo desenvolver, por meio da análise de relatos de idosos encarcerados em um estabelecimento prisional brasileiro, interseções entre as categorias tempo e proteção. Para tanto, desenvolveu-se um estudo de caso com abordagem qualitativa. Dessa maneira, durante a coleta dos dados, foram utilizadas as técnicas de observação direta e de aplicação de entrevistas semiestruturadas. A pesquisa foi realizada no ano de 2022 e contou com a participação de 12 internos do sexo masculino, com 60 anos ou mais, que se encontraram à época custodiados na Penitenciária Lemos Brito (PLB), instituição localizada em Salvador/BA e destinada a condenados ao cumprimento de pena privativa de liberdade em regime fechado. Em campo, as descobertas descobertas que os interlocutores, além de cumprirem penas longas, relatam trajetórias pretéritas de múltiplas vivências, incluindo o exercício de atividades laborais por longo período e a formação de famílias extensas. Logo, a ruptura temporal pelo encarceramento assumido de formas particulares entre os idosos internos, assumindo uma intensidade própria atrelada ao sentido de não vivenciarem parte específica de seus veículos em liberdade. Identificou-se também que, diferentemente de outras unidades prisionais do país, na PLB, a maioria dos internos idosos realizavam atividades relacionadas ao trabalho prisional. Nota-se que os entrevistados que exercitaram tais trabalhos conseguiram a redução concreta do seu tempo de pena, através da remição, e possuíam uma percepção de que o tempo passava mais rápido. Assim, conclui-se que, na perspectiva dos interlocutores, o tempo está no centro das disputas materiais e simbólicas que envolvem o cumprimento de pena.

This paper examines the trends in the use of the Dice (Czekanowski-Sørensen) similarity index in studies of algae and cyanoprokaryotes. A concise overview of the characteristics of this metric is provided, considering its positive aspects and limitations. The relevance of the work is justified by the researchers' need for automation of Dice index calculations and the construction of resulting matrices. The article proposes a method for automating calculations using macros in the Excel environment. The authors provide an overview of the possibilities of this approach and offer their own macro for fast and convenient calculation of the Dice index without the need for third-party programs or formulas.
Aborto por estupro nas redes sociais no Brasil: entre narrativas de sucesso e dicotomias morais
Authors: Assis Mariana Prandini , Santos Nara Menezes
Published: September 2024

Nos últimos anos, diversos casos emblemáticos de meninas que engravidaram em decorrência de estupro ocuparam o noticiário brasileiro. Os obstáculos que enfrentaram no acesso ao direito ao aborto mobilizaram o debate público, especialmente através das redes sociais. Nesse contexto, utilizando um referencial teórico-analítico sobre as disputas narrativas e o enquadramento dos movimentos sociais nas redes, este artigo analisa a abordagem de dois dos principais casos mais recentes no Twitter/X. Para isso, são utilizadas metodologias quantitativas e qualitativas. Por um lado, são analisadas as redes de troca de mensagens, suas relações de influência e contágio, e a automação no Twitter/X. Por outro lado, as narrativas são categorizadas a partir de topic modelling, incorporada à análise qualitativa e com ênfase nas narrativas a favor e contra o direito ao aborto para compreender como o imaginário social é disputado nas redes. Conclui-se que as narrativas sobre os direitos sexuais e reprodutivos tiveram sucesso em influenciar a esfera pública e promover ideias com efeitos positivos para a garantia dos direitos das vítimas. No entanto, essas mesmas narrativas reproduziram uma dicotomia moral entre abortos “bons” e “maus”. Portanto, é necessário superar tais antagonismos para que todas as pessoas tenham liberdade reprodutiva no futuro.
From Chief Cupbearer to Chief of the Guard: Towards a Closer Identification of the Role Presumed by the Noun רַב in the Tanakh
Authors: Howes Llewellyn
Published: September 2024

This study aims to investigate the Hebrew noun רַב , which carries the principal meaning of "chief." In particular, the study attempts to determine whether the noun implies anything about the entity it represents without making this explicit. The study, therefore, analyses the occurrences of the noun רַב in the Tanakh to determine whether the noun implies anything about the individuals it designates, irrespective of the literary context. As far as I know, this exercise has not been attempted with the noun רַב before, which is the unique contribution of this publication. In the Tanakh, the noun רַב does not appear on its own in the absolute state but is exclusively used as part of construct formulations. In each case, the analysis begins by focusing on the lexical meaning, etymology and textual application of the nomen rectum (i.e. the noun that follows רַב in the construct term) and ends by considering the nomen regens, which is always רַב in our case.

Cotton is a resilient and multipurpose crop, meeting major of the world’s textile needs while also yielding byproducts like edible oil and animal feed. Starch plays a crucial role in cotton fabric production. It enhances fabric strength by forming a protective film around cotton fibers, making them more resistant to wear and tear. BES1 (brassinosteroid insensitive 1) is a key regulator in brassinosteroid signaling. It controls thousands of target genes involved in development processes. Interestingly, two β-amylase proteins (BAM7 and BAM8) are part of the BES1 family, despite their primary function as β-amylases. β-Amylase (BAM) and BES1 are two gene families with functional and regulatory roles in controlling shoot growth and development by mediating brassinosteroid effects. They share similar domains and participate in various biological processes, tolerance and responses to stresses like salt and drought. In a computational analysis comparing Arabidopsis and Gossypium species, BAM and BES1 were characterized. BES1 genes were grouped into four clusters based on the comparison of the two species. Two clusters corresponded to BAM7 and BAM8, while the other two clusters were associated with BES1. The conserved nucleotide domain sequence is GCTGGATGG. Short tandem repeats include TG and TTG, which can serve as molecular markers. BES1 is specifically linked to cellulose and fiber production and holds promise as a candidate for plant selection and breeding in Gossypium (cotton).

Authors:   Lomonosov Moscow State University (MSU), Russia, Odinstov Pavel
Published: September 2024

This article develops the discussion initiated by the Gabriel Tupinambá’s Desire of Psychoanalysis, which needs to be supplemented by a clarification and revision of the attitude established in Lacanist discourse towards other disciplines and domains — first of all, science and politics. The position of psychoanalysis in relation to them appears to the author to be problematic and inconsistent with the theoretical level of psychoanalysis itself. In other words, in the interaction with other areas, the analysis feels much less confident than in the clinic and in working with its own concepts. The author hypothesizes why, among other disciplines, psychoanalysis invariably finds itself in this position. Following Tupinamba, it is argued that the main causal factor is the specific topology of the unconscious, which was established by Sigmund Freud and further developed by Jacques Lacan. In the clinic, in conversation with the general public, in dialogue with other disciplines, in each of these dimensions of psychoanalysis’s existence this topology is triggered and generates its effects, for which psychoanalysis eventually has to pay the price in its own territory. The inherent form of the axiomatic topology gives psychoanalysis certain advantages, but today it is time to state that psychoanalysis can no longer exploit its resources and must radically reconsider it and the long-term strategic problems related to it. The positions from which this revision is tentatively proposed are intended to mark and interpret the current crisis of the psychoanalytic community.
Fight Club, Capitalist Gothic, and the Meaning of Interpretation
Authors:   National Research University — Higher School of Economics (HSE University), Pavlov Alexander ,   Institute of Philosophy, Russian Academy of Science (RAS), Moscow, Russia
Published: September 2024

The paper provides an analysis of multiple interpretations of the cult film Fight Club. The author divides the readings of the film into three types — judgment interpretations, theoretical, or methodologically thorough interpretations, and argumentative interpretations. Further in the paper the author groups these interpretations under several headings — Henry Giroux’s Fight Club reading; a critique of the film as a sexist and patriarchal one, feminist interpretations, that make an emphasis not on criticizing, but on Marla Singer’s character; readings of the film as a “fascist,” “anarchist,” “nihilist” one; the analysis of the film as a postmodernist work etc. The author separately distinguishes several argumentative interpretations, that he characterizes as more adequate, while their authors seek to avoid sharp evaluation statements and are more focused on a consecutive analysis. Furthermore, the author proposes his own interpretation, stating that he does not believe it to be final or abolishing. This note gives him an opportunity to show a problematic nature of a main procedure in English-language humanities. In his reflections the author arrives to a conclusion that Fight Club’s universe may be characterized as a world of triumphant “gothic capitalism” (Anna Kornbluh). The paper closes with a discussion on the meaning of interpretation in contemporary humanities.

Публикация вводит в научный оборот малоизвестные тексты из двух коллекций монгольских рукописей и ксилографов, находящихся в Монголии, — в квартире-музее академика Ц. Дамдинсурэна и в личном собрании его ученика Р. Отгонбаатара. Издание предназначено прежде всего для специалистов по монгольской культуре и литературе, но может представлять интерес и для филологов и антропологов, изучающих религиозные, культурные и литературные традиции других народов.
A Robust Solution for Tea Leaf Classification using the SMOTE and Soft Voting Classifier
Authors:   Department of Computer Science, CHRIST (Deemed to be University), Bengaluru, Karnataka, India, Gaba Ira , Ramamurthy B
Published: September 2024

Background/Objectives: The purpose of the proposed work is to identify how a tea leaf is conceptualized. This further enables the categorization of leaves into healthy and unhealthy groups, assisting both the vendor and customer in obtaining the right quality for their requirements. The primary cause of the low production of tea in various parts of the country is the late detection of diseased leaves. Literature suggests that the current AI techniques can detect but have a high level of similarities. Hence, the objective is to identify diseased leaf images at early stage. Methods: Earlier studies have used mostly CNN for classification which is more time consuming, and they create their own parameters. In this study, we extracted the textual features of images by using GLCM, and further classification was implemented with the help of SMOTE and a soft voting classifier. Findings: The proposed method resulted in optimal timeline without using CNN for classification. The accuracy is better when compared to current methods. Novelty: This work presents a novel approach in calculating textual features of leaves that can be further used for classification or tea-leaf grading purposes. Keywords: Image processing, Feature extraction, GLCM, SMOTE, Voting classifier

Authors:   Research Scholar, Department of Manufacturing Engineering, Annamalai University, Chidambaram, 608002, Tamil Nadu, India, Kumar P John Raj , Baskaran A
Published: September 2024

Objectives: This investigation analyzes the microstructure, mechanical and corrosion characteristics of SMO 254 joints welded using constant current TIG (CCTIG) and pulse current TIG (PCTIG) with alloy 625 (ERNiCrMo-3) filler metal. Method: Optical microscopy and SEM with EDAX were employed for microstructural characterization and phase analysis. Mechanical properties were assessed through Vickers microhardness, tensile, and Charpy impact tests, followed by fracture analysis. Findings: EDAX point analysis indicates reduced Mo segregation and the absence of Nb segregation in PCTIG weldments. The overall corrosion resistance remains acceptable despite a slightly higher corrosion rate in PCTIG weldments. The study highlights the superior mechanical properties and microstructural control achieved with PCTIG welding, making it a preferable technique for SMO 254 joints. Novelty: Notably, the research establishes PCTIG as a superior method for welding SMO 254, demonstrating that it not only refines the grain structure but also significantly enhances mechanical properties, particularly toughness, by 50% compared to CCTIG. Keywords: SMO 254, SASS, Microstructural characterization, Mechanical properties, CCTIG, PCTIG

Published: September 2024

Objectives: The main objective of the proposed investigation is to enhance the voltage stability of Radial Distribution System (RDS). It is achieved by proper allocation between combined Electric Vehicle Charging Stations (EVCSs) and Distributed Generators (DGs) in RDS. Here, three objective functions such as Real Power loss, Average Voltage Devotion Index (AVDI) and Voltage Stability Index (VSI) are considered. Methods: The multi-objective optimization problem is implemented using a novel and an effective Pelican Optimization Algorithm (POA) to attain the best compromised solutions. POA is a nature inspired parameter less optimization tool and it is well suited for solution of complex, non-linear voltage stability problem. It determines the most excellent site and size of the EVCSs and DG units. The control parameter of POA considered are population size as 40, the number of variables as 8 and the maximum number of iterations as 100. MATLAB 14.0 platform is utilized for the projected problem. Findings: The bench mark test system of IEEE-33 node system is considered to authenticate the presentation of planned POA methodology. The outcomes such as minimized power loss and AVDI, improved voltage at each bus and VSI are presented. The percentage of loss reduction 39.30% is enhanced, when compared with the base case approach and 5.42 % more improved than the other existing methods like TLBO and HHO approaches. Similarly, the VSI 24.96 % is improved, when compared with the base case method and 1.58 % better than the other obtainable methods. Novelty: The POA is a newly urbanized and well-designed optimization algorithm. It efficiently reaches the global optimal solutions with less time duration. The comparative study with the existing algorithm of TLBO and HHO is considered to prove the performance of Projected POA approach.
