Published: April 2023

Due to their programmability via specific base pairing, self-assembled DNA origami structures have proven to be useful for a wide variety of applications, including diagnostics, molecular computation, drug delivery, and therapeutics. Measuring and characterizing these structures is therefore of great interest and an important part of quality control. Here, we show the extent to which DNA nanostructures can be characterized by a solid-state nanopore; a non-destructive, label-free, single-molecule sensor capable of electrically detecting and characterizing charged biomolecules. We demonstrate that in addition to geometrical dimensions, nanopore sensing can provide information on the mechanical properties, assembly yield, and stability of DNA nanostructures. For this work, we use a model structure consisting of a 3 helix-bundle (3HB), i.e. three interconnected DNA double helices using a M13 scaffold folded twice on itself by short DNA staple strands, and translocate it through solid-state nanopores fabricated by controlled breakdown. We present detailed analysis of the passage characteristics of 3HB structures through nanopores under different experimental conditions which suggest that segments of locally higher flexibility are present along the nanostructure contour that allow for the otherwise rigid 3HB to fold inside nanopores. By characterizing partially melted 3HB structures, we find that locally flexible segments are likely due to short staple oligomers missing from the fully assembled structure. The 3HB used herein is a prototypical example to establish nanopores as a sensitive, non-destructive, and label-free alternative to conventional techniques such as gel electrophoresis with which to characterize DNA nanostructures.

Authors: Ribeiro Alessandro Jacques
Published: April 2023

O que se entende por Álgebra e seu Ensino tem sido combustível para o projeto de pesquisa “Conhecimento Matemático para o Ensino de Álgebra: uma abordagem baseada em perfis conceituais” (OBEDUC/Capes), cujo objetivo geral é investigar os conhecimentos algébricos desenvolvidos por professores, ao ensinar Álgebra na Educação Básica com uma abordagem de ensino baseada em perfis conceituais. A pesquisa é desenvolvida por um grupo heterogêneo que trabalha em colaboração, para elaborar, desenvolver e analisar atividades matemáticas que contemplem diferentes significados de conceitos algébricos. Numa outra dimensão, investiga-se se e como a abordagem de perfis conceituais pode contribuir para constituir e/ou ampliar conhecimentos algébricos de professores e futuros professores. O objetivo específico deste artigo é apresentar e discutir as múltiplas “vozes” da Educação Básica em torno das diferentes compreensões da Álgebra e de seu Ensino. Dentre os principais resultados, revela-se como essas diferentes compreensões podem levar professores formadores e professores da escola básica a tomar essa importante área do conhecimento matemático “apenas” como um amontado de símbolos e procedimentos, na maior parte das vezes, desprovidos de significados
A questão da sustentabilidade ambiental no ensino de Química
Authors: Ayres Fernando Martins , Amaral Carmem Lúcia Costa
Published: April 2023

Embora sustentabilidade ambiental seja um conceito bastante discutido na literatura, torna-se cada vez mais evidente o avanço da degradação ambiental, juntamente com o consumo excessivo de recursos naturais por consequência do comportamento humano. A Química aplicada de forma inconsequente, geralmente é uma das causadoras da degradação ambiental, mas, ao mesmo tempo, quando utilizada de forma responsável, pode ser uma solução, ou seja, pode ser uma aliada à sustentabilidade ambiental. Pensando na importância desse tema, foi realizada uma revisão da literatura com o objetivo de investigar como a sustentabilidade ambiental está sendo discutida no ensino química, principalmente no ensino superior. Para isso realizamos uma busca na web por Instituições de Ensino Superior (IES) que ofereciam cursos de química nas regiões sudeste e sul do país. Selecionamos as públicas federais e estaduais mais antigas. Em algumas IES entramos em seus sites com o objetivo de verificar se essas ofereciam alguma disciplina relacionada ao meio ambiente e/ou desenvolviam em seus campi alguma ação de gerenciamento de resíduos químicos. Os resultados dessa revisão apontam que a sustentabilidade ambiental é uma das preocupações dos professores e pesquisadores que lecionam nos cursos de química de IES públicas federais e estaduais dessas regiões.

The study determined the influence of the Central Bank Digital Currency (CBDC) on the financial markets during the COVID-19 pandemic. It investigated if the CBDC had the potential to improve the efficiency and lending power of the financial system. The research relied on secondary data from a range of financial markets, such as the FTSE, MSCI, Gold Index, S&P 500, and Dow Jones, collected during the COVID-19 period. The quantitative approach was employed using the statistical software SPSS to perform descriptive statistics and regression analysis. The results revealed that the financial markets were negatively impacted by COVID-19, but the CBDC saw a higher level of development during the same period. The statistical analysis showed a positive and significant relationship between the CBDC Attention Index, the Uncertainty Index, and various financial market indices, with regression analysis indicating a significant impact of the CBDC Attention Index on all financial market indices except the Gold Index. However, this study has some limitations, including its limited scope of financial markets. Despite this, these results have important implications for academics and policymakers. It is recommended to increase the use of CBDC through well-crafted policies and legislation to fully realize its potential impact on the financial system. Doi: 10.28991/ESJ-2023-SPER-013 Full Text: PDF

“An Icelandic Driver”: J. Magnús Bjarnason’s Story as a History of Immigrant Hierarchy, Erasure, and Antisemitism in Nineteenth-Century Halifax: A Translation
Authors: Lalonde Jay L.
Published: April 2023

“An Icelandic Driver” is the first English translation of the short story (or novella) “Íslenzkur ökumaður” by the Icelandic-Canadian writer Jóhann Magnús Bjarnason. The story, first published in 1910, offers a unique point of view on turn-of-the-century Halifax, Nova Scotia. While most texts by Icelandic immigrant authors narrowly focus on the experience of their compatriots in isolated rural settlements, this story provides a much richer and more complex portrayal of urban—rather than rural—life. It is inhabited by various immigrants, foreigners, and outsiders, who shape the protagonist’s understanding of his new home. While this portrayal allows for a much more nuanced view, it also reveals a rigid immigrant hierarchy, xenophobia, and antisemitism—all omnipresent and to a large extent internalized by the protagonist.

Insights Into the Application of Polyaniline-Based Composites in Environmental Engineering
Authors: Jovanović Aleksandar , Bugarčić Mladen , Marinković Aleksandar , Sokić Miroslav
Published: April 2023

Environmental management demands innovative techniques for its protection and treatment. The essential agreement of the modern world is to overcome every issue in a sustainable way. The two major financial problems in this area are water pollution and material corrosion. Persistent, organic compounds such as pesticides have devastating effects on the water ecosystem. This problem can be solved by applying advanced treatment processes (ATPs) like membrane separation and photocatalysis. Additionally, the corrosion of metal materials needs to be prevented to preserve natural resources and reduce environmental concerns. Therefore, researchers are trying to develop tunable, multifunctional materials with broad applications. Employed materials in these operations must fulfill high criteria, like durability, stability, and chemical and optical activity, to make specified processes efficient and viable. Electroconductive polymers (ECPs) can meet the aforementioned standards. The most used ECP is polyaniline (PANI), due to its catalytic and electrochemical performances. These two properties are beneficial for both water purification and anticorrosion applications. The objectives of the paper are to represent various PANI-based composites utilized in the removal of different classes of pesticides during wastewater treatment by adsorption or photocatalytic degradation. Further corrosion inhibition, utilizing PANI-based inhibitors, will be discussed as well.

This study was aimed to toxicity, renal-protective and hepato-protective effect of crude methanol extract of M. oppositifolius honey mixture in rats. Methods: The powdered leaf extracts of M. oppositifolius was extracted by cold maceration using methanol. The acute toxicity, hepatotoxicity and renal-toxicity profile of the crude extract of M. oppositifolius were carried out using standard laboratory procedures. Results: The result showed that Mallotus oppostifollous administered orally had LD50 above 5000mg/kg and showed no toxic effect on the blood, kidney and liver of the rats when used orally. It stabilized the blood hematology and biochemical parameters. It showed no significant elevation on the creatinine, blood urea nitrogen and uric acid and therefore showed that the honey combination could have a stabilizing effect on the vital organs of the rats. Conclusion: We therefore conclude that the crude extract of Mallotus oppostifollous has no toxic effect against the kidney, liver and blood parameters and therefore is safe for consumption as a phytomedicine. Therefore, we recommend its continued usage for the treatment of diseases.

Published: April 2023

Traffic congestion difficulties have resulted in low productivity, significant air pollution, and energy losses in Owerri Metropolis, Nigeria. The paper looked at the design of a smart fuzzy logic traffic light management module, the development of a traffic control program using an Arduino microcontroller system, and the validation of the developed program's functionality using a Proteus circuit model to confirm the efficiency of fuzzy signal control. The traffic light environment of a fuzzy logic controller is simulated using Matlab software, and isolated traffic of multiple junctions is simulated using the Sumo Urban Mobility Simulation (SUMO) environment. The performance of the traditional fixed-time controller vs the fuzzy logic traffic light controller is examined. To allocate pedestrian crossing the right of way, traffic light systems function in tandem with pedestrian displays. The simulation results indicated that the overall durations for the fixed traffic light controller and suggested smart fuzzy logic traffic light controller simulations are 1,426 seconds and 1,328 seconds, respectively. The results also showed that the suggested smart fuzzy logic traffic light controller recorded significant waiting and movement times, indicating its standard appropriateness for Owerri city's various crossings.
Attenuation of short-term increased oxidative stress during martial arts competitions, and benefits of micronutrients for martial art athletes
Authors: Tyler M Delarosa  , Kedar N Prasad
Published: April 2023

Interest and participation in competitive Martial Arts such as Taekwondo, Karate, Kung Fu, Aikido, and Tai Chi is growing in children, adolescent as well as in adults in the USA and worldwide. Competitive Martial Arts require daily training weeks and sometimes, months prior to the start of a competition or tournament. The training period could be for a few hours daily over a period of one to six months with one or two days for every one week for rest and recovery. The types and extents of injuries after competition depend upon the form of Martial Arts and the type of physical contact. They include muscle, joint, head and neck, groin, upper and lower extremities, and soft tissues. Some acute injuries can be taken care of at home and the injured may recover quickly. Some injuries may require hospitalization and even surgery; while others may take longer period to recover and require stoppage in training. The training involves daily exercises during which moderate levels of reactive oxygen species (ROS) are produced. ROS activates a transcriptional factor Nrf2 (nuclear factor-erythroid 2-related factor 2) which enhances the levels of antioxidant enzymes; and thereby, reduces oxidative stress. Because of this observation, some investigators have suggested that supplementation with micronutrient and antioxidant compounds is not necessary for reducing injuries and improving the rate of healing from injury. Appropriate diet recommended for Martial Arts athletes are sufficient to reduce oxidative damage and protect against injuries that occur during Martial Arts competitions. The use of a single antioxidant in reducing oxidative stress has produced inconsistent results in reducing the markers of oxidative stress. The limitations of such an approach are briefly discussed. This review has proposed a mixture of micronutrients which may reduce oxidative stress and improve performance in Martial Arts competitions. In addition, some beneficial effects of Martial Arts are also described.

Aim: To isolate and identify the bacteria and fungi associated with the deterioration of Cocoyam with their respective percentage occurrences. Method: Cocoyam Colocasia esculenta (Taro) corms were obtained from a local barn in Umuahia, Abia State Nigeria and transported aseptically to the laboratory for further microbiological analysis. Sterile knife and forceps were used to obtain spoilt tissues from the cocoyam corms. A portion of the spoilt part of the cocoyam was cut out using the sterile knife and was inoculated into Nutrient agar and MacConkey agar plate for growth of bacteria. Another piece of the cocoyam was placed on potato dextrose agar for growth of fungi. Results: Bacterial isolates such as to Escherichia coli, Klebsiella pneumonia, Staphylococcus epidermidis, Staphylococcus aureus, Serratia marcescen and Bacillus subtilis were isolated from the samples. While fungi such as Aspergillus niger, Aspergillus flavus, Rhizopus stolonifer and Rhodotorula spp were equally isolated. Staphylococcus aureus had highest number of microbial isolate with total number of 8 (19.0%), follow by Klebsiella pneumonia with microbial isolate of 7 (16.7%), Escherichia coli and Aspergillus niger had 6 microbial isolate with frequency of (14.3%) each respectively, while Serratia marcescens, Rhodotorula spp while Aspergillus flavus had the least microbial isolate of 1 (2.4%). The presence of these organisms are responsible for the deterioration of cocoyam. Conclusion: Microbiological changes takes place during the storage of Cocoyam Colocasia esculenta (Taro). Therefore, there is need for better processing, handling techniques, good hygiene practices, safety and storage of the finished product. Findings obtained may be useful in the handling and storage of Cocoyam flour.
Utility of incision /excision (Utkartana) in poisoning: A theoretical analysis
Authors: Dilip Kumar Goswami
Published: April 2023

Poisoning can be accepted as the common and most challenging situation for the human society. Exposure to poison is an old age experience of the human society. It is a dreadful situation as it has the potency to cause death even immediately, before installation of treatment and, in most of the situations, after application of the best available measures of treatment. UTKARTANA (Incision /excision) is a method of treatment mentioned among the 24 treatment modules of treatment of poisoning by the Ayurvedic scholars. Under this headings (heading)the victim of poison / physician is advised to cut away (excise) the part affected, if possible, or advised to give incisions on the affected part to expel out the poison by squeezing or sucking through it. It is expected that, if the affected part will be cut away immediately then the poison will not be able to spread to the other part of the body. On the other hand, if immediately incisions will be given at the site through which poison entered and the poisoned blood will be expelled out by squeezing or sucking then also there is scope of expelling out of the poisoned blood and the quantity of poison in the system will reduce. Ayurvedic classics recommend this process in poisoning, specially in snakebite. But there are some controversies in it’s applicability. Hence throwing light on this topic can be considered to have importance and impact.

Authors: Othmane Zakaria
Published: April 2023

The world has been greatly influenced by globalization which inspires many students around the world to study abroad. Learning has no barriers and new education standards recognize the importance of venturing towards new environments, exploring different cultures and breaking misrepresentations. Existing theoretical models related to the field of intercultural learning have demonstrated the significance of studying abroad in enhancing the students’ awareness at various levels. The current paper is an attempt to investigate the impact of such experience in Morocco on a group of American university students who spent one-year learning content courses and practicing Modern Standard Arabic. Based on convenience sampling, 23 American study abroad students have been invited to take part in this study and respond to a survey containing 27 items. Students’ answers were collected before and after completing the experience in Morocco. A likert scale served to get feedback for quantitative statistics while qualitative data has been obtained via semi-structured interviews, conducted with 5 volunteers. All the data gathered was meant to help answer three research questions, namely · What are the challenges American study abroad students faced while studying in Morocco? · What is the impact of the study abroad experience on the students’ language learning and personal growth? · What are the factors that enhance the students’ intercultural awareness? The data analysis and interpretation revealed that the experience had a significant contribution to the students’ language growth, personal development, intercultural awareness, and professional enhancement.

Published: April 2023

This paper explores the ethical dilemmas associated with data and science engineering, with a focus on privacy breaches, algorithmic biases, and the need for transparency. With the increasing reliance on data-driven decision making and machine learning algorithms, the ethical implications of these technologies have become a pressing issue in various sectors. The study aimed to identify the most significant ethical concerns, analyze their impact on society, and provide solutions to address these issues. The research utilized a systematic review of 18 studies to identify the key ethical issues in data and science engineering. The findings revealed that privacy breaches, algorithmic biases, and lack of transparency were the most prevalent ethical concerns. These issues can have significant implications for individuals and groups, including discrimination, loss of autonomy, and reputational harm. The study also identified vulnerable groups, such as marginalized communities, who may be disproportionately affected by these issues. To address these ethical concerns, the study proposed several solutions, including the development of ethical guidelines, increased transparency and accountability, and the use of diverse and representative datasets. The solutions were informed by the literature review, case studies, and analysis of real-world examples. The study also assessed the feasibility of implementing these solutions and highlighted potential barriers to implementation.

Objective: The objective of our study is to compare two implant techniques: extraction immediate implantation and delayed implantation with respect to soft and hard tissue modifications. In the maxillary and mandibular sector including all sextants with the exclusion of wisdom teeth. Materials and method: It’s a study prospective and comparative, it was performed on 102 implant sites, from December 2016 to March 2021, divided into two groups, 54 cases of delayed implantation and 48 cases immediate implantation in both jaws and including all sextants. The oral cavity can be divided into six frames; we therefore speak of a sextant. The sextants are respectively: the upper right premolar-molar group, the maxillary incisor-canine, the upper left premolar-molar, the lower left premolar-molar, the mandibular incisor-canine and finally the premolar lower right molar. Patients were followed for 6 months, during which time tissue changes and osseointegration were assessed using a NABERS periodontal probe and Radio Visio Graphy (RVG). Results: We did not obtain any rejection in the 2 techniques. For immediate implantation: osseointegration (OI) was obtained especially at 4 months for most of the implants. The loss of keratinized fibro mucosa (KFM) was localized to the mandible, it concerned sextant 4, much more for bone type 3 and 1, on the other hand the gain was observed at the level of sextant 1 and 6, especially for type 2 bone. The gain in the mesial bony crest (MBC) and distal bone (DBC) were higher in the male gender in the II compared to the female gender. The mesial fibro mucosa (MFM) was superior compared to the distal fibro mucosa (DFM) at 1 month and at 6 months. For delayed implantation: Osseointegration (OI) was mainly at 5 months for most of the implants. The loss of the keratinized fibro mucosa was localized at the level of the two maxillae. The gain in the mesial bony crest and distal bone were higher in the female gender in the (De) compared to the male gender Conclusion :It is difficult to find a consensus within the current literature as to the superior interest of the technique compared to the other but at the end of this work, we can conclude after the analysis of our results that the II is preferable to IR because it makes it possible to reduce manipulations on the soft tissues, limit the resorption of hard tissues and the filling of the papillae more quickly after loading of the implant more than in the delayed technique, this of course if the preservation of the papillae was performed during the dental extraction, hence an atraumatic or so-called periodontal extraction.

Household surveys collect information on social and demographic characteristics in which the household constitutes the sampling units. They are effective means of obtaining variety of data needed for informed policy formulation and monitoring of national development. Despite their increasing recognition, household surveys suffer from non-response which creates bias estimates leading to wrong inference if not properly addressed. Existing estimators for handling missing values focused on the quality of missing value estimates without considering the resulting effects on location and scale parameters with regard to the nature of missingness and number of missing values. The convoluted weighted method was more efficient than the existing estimators with increasing number and nature of missingness. Its use will enhanced the level of precision of the estimated population parameter in the presence of missing values in household surveys.
Using self-assessment to enhance self-regulated learning – an intervention study in a Finnish lower secondary school
Authors: Mäkipää Toni , Salo Olli-Pekka
Published: April 2023

The aim of this intervention study was to explore how the emphasised use of self-assessment in Swedish classes affects ninth graders’ perceptions of self-regulated learning and their self-assessments in Finland. The dataset includes the survey responses of 36 students and their written self-assessments. The results suggest that the quality of the self-assessments increased during the intervention, although the level of reflection was still superficial. The students exhibited more positive perceptions of their skills in self-regulated learning at the end of the intervention. The results indicate that incorporating self-assessment into teaching boosts students’ perceptions of self-regulated learning and enhances the quality of their self-assessments. Swedish teachers should consider the extent to which they use self-assessment in courses and whether their practices could be adjusted to promote reflection and self-regulated learning.
Intorno a Takemitsu e Hosokawa (con una digressione)
Presentazione del concerto Due omaggi del 22 febbraio 2022
Authors: Notargiacomo Paolo
Published: April 2023

In presenting the concert Due omaggi, dedicated to the music of Takemitsu and Hosokawa, but also to the influences and suggestions of Japanese aesthetics on the Western world, the author briefly illustrates the dialogue between European and Japanese music that runs through the entire modern era, from fin de siècle Japaneseism to the most recent neo-avant-garde aesthetics. The history of this long and rich relationship, made up of exchanges, loans, contaminations, mirrorings and mutual identifications, is, in fact, a necessary premise for understanding a large number of elements, choices and aspects that characterise contemporary music on both sides. In the light, then, of this profound liaison, the individual pieces that make up the varied programme are framed and described.
Recensione di Anche la notte profuma il gelsomino
Venezia, Conservatorio di Musica Benedetto Marcello, 23 febbraio 2022
Authors: Pugliese Edoardo
Published: April 2023

The Aesthetics of Emptiness: this is the title of the series of concerts, master classes, conferences, exhibitions and guided tours dedicated to 'emptiness' as the heart of Japanese aesthetics, which took place in Venice from 21 to 24 February 2022. And even in the music of the concert Anche la notte profuma di gelsomino, masterfully interpreted by the duo formed by Chisato Yamamoto on violin and Cecilia Franchini on piano, one could perceive the concept of absence in music, which is not mere silence but a more intimate, nuanced and elusive sensation.
Lo Zen e l’estetica del vuoto
Forme dell’arte nella Via del Buddha
Authors: Tollini Aldo
Published: April 2023

The coming to power of the bushi clans from the late twelfth century stimulated the emergence of a peculiar Japanese culture and aesthetics, with different characteristics from those that had prevailed in the aristocratic milieu of Kyōto in the previous period. The close relationship that had developed between the warrior class and the new Zen school coming from China stimulated the acculturation of the warriors and their appreciation of the arts. Zen, in fact, acted as an intermediary transmitting the great continental culture to the archipelago where, adapted to the Japanese environment where a virile character, marked by rarefied values of essentialism prevailed, gave birth to extraordinarily precious fruits characterised by great elegance and by a high spiritual sensibility. This essay aims to describe some aspects of what is called the ‘aesthetics of emptiness’ inspired by the doctrines of the Zen school.
L’estetica del vuoto: l’universo in un cerchio
Authors: Vesco Silvia
Published: April 2023

The definition of the ‘aesthetics of emptiness’ could be problematic in itself and, perhaps, even misleading, since it is based on some assumptions that are almost taken for granted in the West but which have no correspondence in the East and, above all, in the Chinese and Japanese contexts. The problem derives, first of all, from considering aesthetics as a specific philosophical discipline in its own right. This idea is not at all confirmed in Japan since a distinction has never been made between theory and practice. So why do we talk about the aesthetics of emptiness? And, above all, in what forms and with what tools has Japan answered this question? This paper tries, through some specific examples, to address these issues and to propose some possible answers.

Objective This study aimed to examine how marital status, occupational status, and individual personality influence suicidal ideation and suicide attempts among Korean middle-aged adults, and explore the effects of their interaction.Methods A total of 2,464 middle-aged adults were surveyed about suicidality in the past year (1-year suicidality). Participants’ current marital and occupational status, including other demographic and clinical variables were investigated. Personality traits were assessed using the Big Five Inventory. The dependent variable was the presence of 1-year suicidality. Independent variables were current marital and occupational status. Generalized linear model (GLM) analysis was performed to adjust for other covariates.Results The group with 1-year suicidality had significantly lower income. It had a lower proportion of full-time employment, and higher percentages of part-time employment and unemployment. The GLM analysis results showed that marital and occupational status had no significant association with 1-year suicidality. Neuroticism and openness were positively associated with 1-year suicidality, whereas conscientiousness and extraversion had a negative association. Interactions between marital status and neuroticism, conscientiousness, and occupational status were significant.Conclusion Individualized social and psychological interventions for suicide prevention are required according to individual personality traits.
