Microtomography Evaluation of The Efficacy of Reciprocating And Rotary Instruments Followed By Different Complementary Steps In The Retreatment of Curved Root Canals
Authors: Campos Fruchi Lincoln de
Published: June 2021

Objectives: The purpose of this study was to evaluate the efficacy of steps, isolated or in cumulative means, in the endodontic retreatment of curved canals.

Methodology: Forty mesial roots of mandibular molars were divided into two groups. In the group 1 the filling removal was done with NiTi reciprocating M-wire and NiTi control memory wire rotary instruments followed by a passive ultrasonic irrigation solution agitation. In the group 2, the initial filling removal was done with NiTi reciprocating M-wire and conventional NiTi wire rotary instruments followed by a rotary plastic instrument for irrigation solution agitation. The results were analyzed through micro-computed tomography.

Results: The filling material was not completely removed for both groups. All steps did not statically differ between groups regarding to the filling removal. In the intragroup analyses, the results differed in some levels, mainly in the apical level, but did not statistically differ in all the different levels after each step. A statistical significant increase (P<.05), for both groups, in the volume of filling material in the isthmus was observed.

Conclusions: None of the protocols completely removed the filling material. The better results were found for the apical level and after passive ultrasonic irrigation. Vertical warm condensation filling technique enhanced the volume of filling material in the root canal system including the isthmus.

Clinical relevance: the control memory NiTi instruments could be considered a good choice for use as an additional step in the procedure of filling removal from curved mesial root canals.

Published: June 2021

Esthetics plays a crucial role in rehabilitation of removable dentures to achieve a pleasant smile. Denture esthetics is the effect produced, which improves the beauty and attractiveness of a person. With the advances of implants and ceramics, the conventional removable denture needs to be updated. denture characterization is a must in avoiding denture look and giving natural look. Giving the prosthesis as close as possible to the natural apparatus before the tooth loss is the key to a successful prosthetic, esthetic and functional rehabilitation. As a prosthodontist dealing in fulfilling the aesthetic challenges an economical alternative to high-end costly procedures is a must considering the Indian scenario, keeping in mind the biocompatibility and longevity of the treatment. As per literature light cure, gum staining is one of the techniques for masking denture base color and imparting natural color to mucosa but considering the cost involved many patients requiring aesthetic enhancement of prosthesis avoid going for such treatment thereby compromising their aesthetic. the present case series describe an innovative cost-effective alternative to the previously describe technique for masking the denture base color by using composite mixed with stains to replicate the natural apparatus.
Indicators and Preferences of Facial Profile and Aesthetic

Published: June 2021

For a successful orthodontic treatment, it is crucial to examine the patient in both frontal and lateral views. Evaluation of the skeletal pattern and softs tissues including nasolabial angle, anteroposterior lip position, labiomental angle, and Lip-chin-submental plane angle must all be considered. Facial profile greatly affects the aesthetic appearance of the patients, however, not every person has the same aesthetic perception. This review aims to point out the indicators of facial profile and the perception of facial profile attractiveness among the different populations. Many studies have evaluated the preferences of facial profile, some of them agreed as a straight profile with normally positioned lips was the most favored, but some differences were noted between orthodontists and laypeople in the perception of the facial profile. Laypeople found a slightly retruded mandible or protruded mandible was found aesthetically pleasing for some populations. Therefore, it is important to involve the patient in treatment planning and decision-making.
Symplectic Keys and Demazure Atoms in Type C
Authors: Santos João Miguel
Published: June 2021

We compute, mimicking the Lascoux-Schützenberger type A combinatorial procedure, left and right keys for a Kashiwara-Nakashima tableau in type C. These symplectic keys have a similar role as the keys for semistandard Young tableaux. More precisely, our symplectic keys give a tableau criterion for the Bruhat order on the hyperoctahedral group and cosets, and describe Demazure atoms and characters in type C. The right and the left symplectic keys are related through the Lusztig involution. A type C Schützenberger evacuation is defined to realize that involution.
Monetary Faith

Published: June 2021

The natural interest rate was the most important variable of monetary economics in the twentieth century. It has lingered in the background of economic policymaking, dictating the terms of debate for economic policy in general, and central bank policy in particular. The central banks pledge that if economists have enough faith in this unseen entity, we all will be the recipients of economic grace.

Published: June 2021

Problems of climate change, environmental pollution, the search for alternative energy sources – these issues, as well as many others that can be characterized as constituent elements of the concept of sustainable development, or the “green” economy, come to the fore, becoming the most relevant in all spheres of human life ... The article formulates the concepts of conscious consumption and conscious investment. The main promising investment trends are identified, preferences in investing generation Z and their impact on the world economy are formulated. As an example of the trend of conscious investment, as well as a promising source of financing for «green» projects, the dynamics of the issue of a specific type of securities – “green” bonds is analyzed. The article analyzes the features of the «green» issue, and also formulates the author’s view on the pricing of this financial instrument. Illustrated is the “green halo effect” inherent in the portfolio of “green” bonds, which characterizes these securities as the most liquid in comparison with classic bonds. The effectiveness of the experience of issues of Russian companies in this segment is analyzed. Based on the results of the study, it was concluded that conscious investment opens up new prospects for the Russian economy, since for many investors today, adherence to the concept of sustainable development is higher than political views, and the growing number of its followers neutralizes the increased risk level of individual investments.

Published: June 2021

Introduction: Quantitative analysis of Mycobacterium tuberculosis using microscope is very critical for diagnosing tuberculosis diseases. Microbiologist encounter several challenges which can lead to misdiagnosis. However, there are 3 main challenges: (1) The size of Mycobacterium tuberculosis is very small and difficult to identify as a result of low contrast background, heterogenous shape, irregular appearance and faint boundaries (2) Mycobacterium tuberculosis overlapped with each other making it difficult to conduct accurate diagnosis (3) Large amount of slide can be time consuming and tedious to microbiologist and which can lead to misinterpretations.

Methodology: To solve these challenges and limitations, we proposed an automated-based detection method using pretrained AlexNet to trained the model in 3 sets of experiments A, B and C and adjust the protocols accordingly. We compared the detection of tuberculosis using AlexNet Models with the ground truth result provided by microbiologist and analyzed inconsistencies between network models and human.

Results: 98.15 % accuracy, 96.77% sensitivity and 100% specificity for experiment A, 98.09% accuracy, 98.59% sensitivity and 97.67% specificity for experiment B and 98.73% testing accuracy, 98.59 sensitivity, 98.84% specificity ofr experiment C which sound robust and promising.

Conclusions: The results indicated that network performance was successful with high accuracies, sensitivities and specificities and it can be used to support microbiologist for diagnosis of tuberculosis.

Published: June 2021

Introduction: In the presence of asymptomatic bacteriuria (ASB) before the urological procedure, the duration of antimicrobial treatment is controversial. This study aims to evaluate whether a short course of antimicrobial therapy is safe and effective in cases with ASB before urological procedures.

Methodology: We retrospectively reviewed adult patients who had ASB before undergoing several urological procedures between 2011 and 2019. The patients received a single dose of an appropriate parenteral antibiotic, determined by antimicrobial sensitivity testing, 30 to 60 minutes before the urological procedure. If a urinary catheter was placed post-procedure, a second dose was given.

Results: A total of 293 patients who had ASB before undergoing several urological procedures were included in the study. The total number of procedures was 328. Female/male ratio was 92 (31.4%)/201 (68.6%). The mean age was 63.7 ± 14.9 years. The most common isolated microorganisms were Escherichia coli (155 [47%]), Klebsiella pneumoniae (38 [11.6%]), and Pseudomonas aeruginosa (28 [8.5%]). The most common antimicrobial used was ertapenem. A second dose antimicrobial was given for 290 procedures due to a urinary catheter after a urological procedure. The mean hospitalization time was 3.97 ± 3.42 days. None of the patients developed infectious complications.

Conclusions: This study has demonstrated that a single dose of parenteral antimicrobial drug administered 30-60 minutes before the urologic procedures and a second dose in the presence of a post-procedure catheter, was adequate to prevent post-procedure septicemia and urinary tract infection.
Penser les lieux du care : fiction, wonder et vies ordinaires
Authors: Hétu Dominique
Published: June 2021

Cet article vise à montrer le potentiel des éthiques du care dans le champ littéraire, plus particulièrement par l’entremise des notions de wonder et d’ordinaire telles que mobilisées dans deux œuvres de fiction contemporaine. L’article pose d’abord des balises théoriques à l’intersection des études littéraires, des éthiques du care , des éthiques de l’ordinaire et des wonder studies afin de circonscrire l’appareil méthodologique. Dans un deuxième temps, on propose une étude comparative de deux romans de l’écrivaine montréalaise Heather O’Neill, La ballade de Baby et Mademoiselle Samedi Soir , lesquels problématisent l’expérience de la pauvreté, de la précarité et de la relationnalité et configurent les sujets fictionnels comme des figures morales complexes dont l’agentivité est façonnée par leur ouverture au wonder et leur rapport au care.
La classification zoologique dans la civilisation arabe classique : approche lexicologique et épistémologique
Authors: Provençal Philippe
Published: June 2021

Cet article traite de la notion d’espèces biologiques dans la culture arabe. À partir d’une approche lexicologique des appellations d’espèces dans la langue arabe, le concept d’espèce en arabe classique et dans quelques parlers arabes contemporains tel qu’il est reflété par les appellations des animaux et des plantes est discuté. Les auteurs arabes classiques de textes de contenu biologique et médical traités dans l’article discutent du concept d’espèce biologique dans leurs œuvres, mais n’arrivent pas à une définition tranchante. En plusieurs cas les termes scientifiques de la zoologie d’Aristote sont jugés comme adéquats. Les auteurs arabes utilisaient plusieurs méthodes différentes pour leur systématisation du monde vivant et ces méthodes sont décrites par des exemples.
Le genre, maître-mot du classement
Authors: Lherminier Philippe
Published: June 2021

Les collections naturalistes, les trouvailles des voyageurs, les cabinets de curiosité, les jardins des simples, apparaissent au 17ème et prennent au 18 e un essor qui pose la question de leur mise en ordre. La fonction classificatoire du genre avait été analysée par les logiciens dès le Moyen-âge, Vincent de Beauvais, Barthélémy l’Anglais, Al-Ğāḥiẓ, Ibn Tufayl, Léon l’Africain, et jusqu’à Borges, en offrent des exemples liminaires, puis définitivement rédigée dans la Logique de Port-Royal  : chaque espèce ordonne plusieurs objets, et cet ordre constitue une classe ; à son tour chaque genre ordonne et compacte plusieurs espèces, et cet ordre constitue une classe de classes : le genre est donc la catégorie du classement. Cependant il faut attendre Tournefort puis Linné et Buffon pour accéder à la notion moderne de classement des êtres vivants par emboîtement hiérarchique de classes.

Comment la surexposition de la région parisienne à la victimation et à l’insécurité se décline-t-elle dans la diversité de ses territoires ? Dans le but de répondre à cette question, notre étude consiste à subdiviser la région parisienne en unités territoriales caractérisées par leurs victimations, leur insécurité, leur composition socioprofessionnelle et migratoire et leurs comportements électoraux. Le croisement de ces données produit une typologie qui confronte les différentes combinaisons de la victimation et de l’insécurité à la diversité de la composition sociale et politique des territoires en Île-de-France.

Un précurseur de Paul Chevalier ? La vie mouvementée de Claude Bresoul, Franciscain de Tournai, « prebtre religieux apostat et hereticque » (1518-1560)
Authors: Meiss Marjorie
Published: June 2021

Le 22 avril 1560, Claude Bresoul est arrêté à Cysoing, près de Lille. Identifié comme un Franciscain ayant abandonné son habit religieux et soupçonné d’adhérer aux idées calvinistes, il est confié à l’inquisiteur de Flandre Pierre Titelmans au mois de juillet. Entre temps, il a été interrogé à six reprises par le prévôt et les échevins de Cysoing. Le contenu de ses interrogatoires offre une occasion exceptionnelle de saisir le parcours de l’un de ces nombreux frères mendiants tentés par la Réforme. S’y dessine le portrait d’un homme mal à l’aise dans une vie religieuse choisie trop tôt et réellement séduit par les options théologiques du calvinisme, devenu un membre actif d’un réseau de coreligionnaires déployé de la Flandre wallonne à Anvers. Il n’est pas impossible que son exemple ait inspiré Paul Chevalier : le futur martyr réformé, monté sur le bûcher en 1564, venait en effet d’arriver au couvent des Franciscains de Tournai lorsque le chapitre eut à se prononcer sur le cas de Claude Bresoul.
L’épithalame de Nicolas Bourbon pour Jeanne de Navarre : du mariage réel au mariage idéal
Authors: Laigneau-Fontaine Sylvie
Published: June 2021

Protégé de Marguerite de Navarre, précepteur de Jeanne d’Albret, le poète Nicolas Bourbon publie en 1549, au moment du mariage de son élève avec Antoine de Bourbon, un long épithalame destiné à célébrer cette union. Or, ce mariage avait été imposé à Marguerite par son neveu Henri II et toutes les sources attestent du mécontentement de la mère de la mariée et du peu de lustre de la cérémonie. Dès lors, pourquoi le poète décide-t-il de chanter un mariage qui déplaisait tant à sa protectrice ? Est-ce pure maladresse de sa part ? L’article veut montrer au contraire que Nicolas Bourbon, conscient du pouvoir d’une poésie aere perennius , a voulu faire de ce mariage, pour l’éternité, un mariage idéal, en demandant à la littérature de corriger la réalité.
La Satyre ménippée et son Supplement : la reconstruction érudite d’un genre ou le pamphlet du déguisement
Authors: Chauffour Julien
Published: June 2021

Pierre Pithou et le groupe d’érudits auteurs de la Satyre ménippée de la vertu du Catholicon d’Espagne tentent de reconstruire un genre savant, la satire ménippéenne, à partir d’un pamphlet royaliste qui circulait déjà sous forme manuscrite. Imprimée à Tours en 1594, la Satyre ménippée , bien qu’elle présente une esthétique ménippéenne et un tour paradoxal, parle d’une seule voix, celle du camp d’Henri IV : il lui manque le vertige interprétatif que provoque la lecture des grands maîtres du genre, comme Rabelais ou Lucien. Dans l’ajout tardif au texte de la Satyre Ménippée qu’est Le Supplement du Catholicon ou les Nouvelles des Regions de la Lune (1595), attribué à Florent Chrestien, il est possible, alors, de trouver la réponse aux problèmes soulevés par le difficile mariage de Pamphlet et Érudition.

Does Economic Freedom Matter for Bank Performance and Energy Consumption?
Authors: Yakubu Ibrahim Nandom , Kapusuzoglu Ayhan , Ceylan Nildag Basak
Published: June 2021

This study investigates the influence of economic freedom on energy consumption and bank performance in Ghana over the period 2000-2017. Specifically, the authors examine the effect of the various components of economic freedom on total energy usage, fossil fuel consumption, and bank performance. The study applies the fully modified ordinary least squares (FMOLS) method to determine the long-run influence of economic freedom indicators on energy consumption and bank performance. The results show that aside from business freedom, all the other sub-economic freedom measures significantly drive total energy consumption. The authors reveal that investment and fiscal freedom significantly influence fossil fuel consumption. The findings also establish that financial, investment, and fiscal freedom indices exert a significant effect on bank performance. These results hold regardless of the measure of bank performance. In light of the findings, the authors discuss relevant policy implications.

Published: June 2021

This study tries to handle the energy issue with an encompassing managerial approach with a broader perspective. In the study, which aims to contribute to the evaluation of the subject from the perspective of entrepreneurship and business administration, efforts are made to explain energy by using the basic principles/approaches that are significant in the business literature. Vital issues such as energy production and energy management are handled based on managerial discipline. It takes care to bring together many different approaches that can be associated with the subject, touching upon essential concerns such as consumption, market, and competition factors. Since the matter can differ in short and long-term outlooks, the concepts of energy and strategy are examined together. In this way, because it stands within the common field of many disciplines, it is desired to make a journey to energy not only with the perspective of the basic science but also through the viewpoint of the social sciences. And the connotations of the concept of energy are deepened.

Authors: Awoyemi Robert Akinade , Awoyemi Richard Oluwadolapo
Published: June 2021

This paper examines the Virtual Learning Environment (VLE) in relation to its implication for academic libraries in the 21st century. It sheds light on how technological development has had major impacts in the academic library, with regards to how information is being constructed, transmitted and accessed by library users. In the course of this discourse it was deduced that students constitute a significant percentage of the academic library users. The technological development in the academic sphere has enabled ubiquitous interactions between students and teachers, in which students are enabled to learn and communicate with their teachers from remote locations, thus inducing the notion of VLE. The VLE is regarded as technological-based environment where learners are enabled to access learning outside the classroom. With the aid of VLE students are granted ownership of their learning process, thus ensuring positive learning outcomes. Finally, the Technology Acceptance Model (TAM) was employed to serve as the theoretical basis of this discourse.

Statistical study of growth kinetics and lipid content of microalgae grown in brackish waters for bioenergetic purposes
Authors: Guimarães Bruna Da Silveira , França Kepler Borges
Published: June 2021

This study aimed to statistically prove the influence of salinity on growth kinetics and intracellular lipid accumulation in microalgae. The species Chlorella sp., Scenedesmus acuminatus, Nannochloropsis sp., Monoraphidium contortum and Pediastrum tetras were studied, which were isolated in the Brazilian semi-arid region and cultivated in synthetic media with the addition of NaCl. From the crops, growth kinetics, dry biomass production and lipid content were analyzed, using the experimental planning for one factor as a tool, with the NaCl concentration as an independent variable. The kinetic parameters maximum growth speed (µmax) and generation time (tg), as well as lipid concentration were the response variables studied. The results showed that, in the species Scenedesmus acuminatus, Nannochloropsis sp. and Pediastrum tetras, salt stress contributed to the increase in µmax and the consequent decrease in tg. The highest levels of lipid accumulation were obtained in Nannochloropsis sp. (62.04%), in the medium with the highest salinity and Pediastrum tetras (54.04%) in the lowest. Dry biomass production was higher in Scenedesmus acuminatus (1,941.37 mg.L-1) and Nannochloropsis sp. (1237.05 mg.L-1), both at a concentration of 4.0 g.L-1. Therefore, saline stress acted directly on the cell growth and lipid content of the species, which can be used as a device to enhance lipid production for the purpose of producing biofuels.
The economics of team sport in Europe: production, monetization, deficit and regulation
Authors: Bouvet Patrice
Published: June 2021

This article deals with the economics of professional sport in Europe. Its objective is twofold: firstly, to propose a "vertical" vision, from production to the necessary regulation, including the study of the conditions for monetising sports shows produced by professional sports clubs in Europe; secondly, to put forward a general explanation for the persistence of deficits (DNCG data and similar organisations) of many of these clubs. This article deliberately places itself, unlike many other contributions, in a global (macroeconomic) perspective. It underlines: the universality and singularity of the production of sports shows, the specific conditions of their monetisation; presents, the origin of the deficits and the means nowadays chosen by professional clubs to try to cope with them and finally leads to an original proposal for regulation.

Giving a Listening Ear: Male Student Teachers’ Experiences and Perspectives of Practicum Supervision
Authors:   University of the West Indies, Mona, Clark Keriffe
Published: June 2021

Exploring the minute number of male teachers within the classroom is certainly not a new discourse as teaching has increasingly become a feminised profession. Therefore, as male student teachers take on the challenge of becoming teachers, it is imperative that we listen to them as they recount their supervision experiences. These experiences are significantly influenced and impacted by teacher educators and cooperating teachers who are tasked with the responsibility to provide high quality and effective supervision, especially during teaching practicum. Additionally, acknowledging that to attain positive outcomes attached to student teaching experiences, Hunt et al. (2015) have reasoned that teaching practicum is essential in the process of developing quality teachers. Thus, the quality of supervision male student teachers need is heavily dependent on the capacity and expertise of those who supervise them. However, Slick (as cited in Bates & Burbank, 2008) posited that within teacher training programmes and colleges, student teacher supervision is not highly regarded.

Questioning Standards of Evaluation in Educational Research: Do Educational Researchers Ventriloquize Learners’ Voices in L2 Education?
Authors:   Concordia University, Bolderiff Anastasia
Published: June 2021

Learners are not stakeholders in their own education. Adhering to the quantitative gold standard in English as a Second Language (ESL) deprives the learner from having a voice in their learning process. This paper addresses voicelessness and ventriloquism in ESL, ventriloquism referring to the act of voicing the thoughts of another person, in this case the system overriding the learners’ experiences. This article addresses this problem, aligning itself with the Platinum standard while challenging the quantitative gold standard in ESL research. This paper offers resonance and semantic reliability as evaluative measures in educational research taken from literary criticism. The notion of resonance has been addressed in the literature on qualitative research since the dawn of the narrative turn; I address how resonance can be used in educational research.
Comparing Girls’ and Boys’ Lived Bodies of Middle School Students in Self-Defense Utilizing Participant Observation
Authors:   Wright State University, Follow Giovanna
Published: June 2021

The Frailty Myth proposes that the female body can be frozen, restricted by the ever present negative gendered narrative perpetuated by society. Embodiment occurs when the female body is thawed. The opposite can be argued for boys. Boys are taught to live their bodies, that is they have a sense of embodiment. Therefore, boys do not have to concern themselves with thawing their bodies as they already experience their bodies in strong and liberal ways. In this study, I compare how girls and boys live their bodies utilizing participant observation. Six themes emerged: being the instructor, gendered discourse in action, body proximity and movement, The Invincibility Effect, the grade six and seven/eight divide and lived body moments. The implications of these observations suggest how activities such as self-defense have the potential to create a lived body, that girls can work toward a lived body and gender can be observed through everyday lived experiences. Though research exists within the literature; it does not seem to address the performance of the lived body within this population, utilizing a comparative approach.

The specially-abled face a lot of issues when it comes to taking up exams. They require specific assistance for taking up their exams known as a scribe. However in today’s world finding a scribe is of great difficulty. Even if the scribe is found there are a lot of other practical difficulties while using a scribe to write exams. One such practical difficulty in using a scribe to write exams is that the scribe may not be aware of the technical terms used by the candidate. This causes loss of marks for the candidate if the scribe makes an error. The scribe should also have a legible handwriting which again is a problem. Our project aims at eliminating the need for a scribe and allowing the candidate itself to take up their exams by leveraging the latest technologies such as speech recognition and synthesis. This is achieved with the help of an android application, using which the questions can be stored in a database using administrator login. A separate candidate login is given. The question will be read out to the candidate and the answer will be taken as a voice response.

Natural disasters are detrimental to many sectors, including the education sector. Schools located in disaster-prone areas are vulnerable to building damages, causing fatalities and psychological problems for students. Pandeglang Regency, especially on its west coast, is a tsunami-prone area and is home to hundreds of elementary to high schools in the area. The purpose of this study is to analyze the implementation of disaster safe schools in three schools with high vulnerability to tsunami: MTs Masyariqul Anwar, SDN Tamanjaya 2, and SD Mekarjaya 3. This research used disaster school survey form issued by National Disaster Management Agency (BNPB) which regulated in Head of BNPB Regulation No. 4 of 2012 on Implementation Guidelines of Disaster Safe Schools. The research findings are MTs Masyariqul Anwar and SDN Tamanjaya 2 have a sufficient safe school level but needs improvement in integrating disaster risk reduction curriculum and strengthening SOPs for safe schools, while SDN Mekarjaya 3 has a poor safe school level which lacking in both structural and non-structural frameworks. This study suggests that efforts to implement disaster safe schools are hampered due to the absence of a curriculum based on disaster risk reduction and poor infrastructure conditions.
