A caixa acústica na novela Florim: expansão de gêneros e autoria
Authors: Góis Edma Cristina Alencar de
Published: November 2021

Resumo A novela Florim (2020), de Ruth Ducaso, dá continuidade ao projeto da escritora baiana Luciany Aparecida que, entre outras marcas, utiliza diferentes assinaturas poéticas a depender da dicção e do efeito que pretende produzir como fatura do texto. Nesta obra, condensada em menos de 70 páginas, o leitor conhece a personagem Dita, uma mulher que trabalha no tráfico de drogas, é vendedora de dendê na feira, tem “nove filho” e sonha ser nomeada poeta. Florim é conduzida por três vozes intercaladas; a voz da narradora Dita, o diário da protagonista e a poesia de Dita. Além das três marcações (narração/diário/poesia), há ainda um quarto elemento, também de destaque em todo o texto, a ser creditado à Ruth Ducaso, a voz do Prólogo. São intervenções entre parênteses, em um primeiro momento lembrando o teatro clássico, e que também evocam as “experiências corais” de que fala Flora Sussekind (2013). Neste artigo, analiso as manobras operadas pela escritora Luciany Aparecida, notadamente a assinatura poética e a expansão dos gêneros, com vistas a observar como alguns empreendimentos do contemporâneo propõem novas formas para o literário. Neles, o leitor em um gesto interessado e ativo não se baseia apenas na noção de reconhecimento, mas lança mão de um repertório performático, comum à poesia e ao teatro. Florim, portanto, apesar de catalogado como “novela”, transcende o formato anunciado, como um exemplar da pós-autonomia.
Autobiografias trans: um levante em formação
Authors: Chaves Leocádia Aparecida
Published: November 2021

Resumo Neste artigo, discuto a produção autobiográfica de autoria trans no Brasil contemporâneo como estratégia de resistência e organização. Trata-se de uma produção, pelos critérios metodológicos estabelecidos, nascida em 1982 e avolumada a partir de 2011, compondo um universo de quinze obras até o ano de 2019. Para discutir essas autorrepresentações como instrumento radical de luta e de luto, contextualizo-as no campo literário contemporâneo, que historicamente confirma-se como transfóbico, seja por representações estigmatizadas e estereotipadas dessa identidade e/ou sua ausência, seja pela exclusão de pessoas trans na instância da autoria. Buscando identificar as estratégias de resistência e organização, proponho acessar as obras selecionadas pela analítica do cuíerlombismo, ainda que em distensões. A partir dessa abordagem cartográfica, destaco o narrar-se como um arquivar-se, o que tanto permite a formação, no espaço literário, de uma comunidade de afeto, de partilha, quanto se constituir como política e dever de memória.
A crise da pós-memória e o horizonte das sobrevivências: campos de batalha da memória no Brasil contemporâneo
Authors: Vecchi Roberto
Published: November 2021

Resumo A reflexão que se propõe neste artigo concentra-se sobre o conceito escorregadio de “pós-memória” que surge na década de 1990 em âmbito cultural e não histórico. Tentando localizar os pontos de força e de debilidade que possui, situados em particular no caso brasileiro, a análise se interroga se esta reconfiguração crítica sobre a memória das segundas e sucessivas gerações tem contribuído - ou não - para se inscrever no debate contemporâneo sobre a salvação de memórias em risco. A prática do “desaparecimento forçado” e sua (im)possível herança mnésica para as outras gerações, oferece um ponto extremo de reflexão crítica. Mesmo surgida no contexto da pós-Shoah, a pós-memória encontra aplicações em diferentes contextos críticos - como no caso dos autoritarismos militares na América Latina e da ditadura militar brasileira (1964-1985). Depois de uma revisão do debate conceitual, a “pars construens” da reflexão procura verificar se a desmontagem analítica da pós-memória associada à figura das sobrevivências (Pasolini, Didi-Huberman, Warburg, Benjamin) oferece uma nova dimensão crítica com que repensar a transmissão da memória e a economia da herança. Desta revisão, articula-se uma política das sobrevivências que talvez possa reformular, em sua aliança com campos como o da literatura ou das artes, uma outra possível relação com o passado.

A abordagem participativa permitiu a aplicação do diálogo sobre o conhecimento, que fortalece o desenvolvimento de ações na perspectiva da promoção da saúde, mas também de uma ciência cidadã baseada em pesquisa participativa.
RC-INSANE – an interactive environment for nonlinear analysis of reinforced concrete structures
Authors: Reges Pâmela Daniela Nogueira , Pitangueira Roque Luiz da Silva , Silva Leandro Lopes da
Published: November 2021

Abstract The development of numerical and computational resources that can present reliable models for the analysis of reinforced concrete structures is mainly driven by its widespread use. Considering that reinforced concrete is a composite material and bond is the load-carrying mechanism, these models must consider that the structural behavior is affected by the interaction between concrete and reinforcement. On this basis, the Finite Element Method (FEM) is a well-established method able to provide consistent results for reinforced concrete modeling through reinforcement and bond models. Nevertheless, to simplify the analysis, the hypothesis of strain compatibility between concrete and reinforcement is usually considered. Under certain loads and specific geometries, this hypothesis is not valid, and the bond-slip phenomenon must be considered to fully characterize the structural behavior. To fulfill this need, this paper presents a graphic interface that enables the modeling of reinforced concrete structures through discrete and embedded reinforcement models, with the possibility to include the bond-slip phenomenon based on several constitutive laws proposed in the literature. The computational implementations were held in the INSANE (INteractive Structural ANalysis Environment), an open-source software based on the Object-Oriented Programming paradigm, which enclosures several constitutive models for nonlinear concrete modeling and different numerical techniques, and a post-processing application able to represent the results by way of a friendly-user graphic interface.
Superspreading event of COVID-19 in adolescents: is there a difference between the vaccinated and the unvaccinated?
Authors: Perelman Carol , Fastlicht Andrea , Sanchez-Flores Alejandro , Wegman-Ostrosky Talia
Published: November 2021

Objective:

The aim of this study is to estimate the incidence of COVID-19 in a vaccinated and an unvaccinated group of adolescents and describe their symptoms.

 

Methods: In May 2021 a private indoor event for high school adolescents took place resulting in a superspreading event. As part of the study, an anonymous questionnaire was sent to all adolescents invited to the event and details about symptoms, previous COVID-19 infection, vaccination status and behaviour during the event was assessed. Two groups were formed, one of vaccinated individuals and the other of unvaccinated individuals. A sample from a fully vaccinated symptomatic individual was sequenced. General characteristics for the studied groups are described using categorical and continuous data. The incidence of COVID-19 in each group was estimated by taking the total number of COVID-19 positive cases (numerator) divided by the total number of individuals (denominator) multiplied by 100.

 

Results: A total of 41 out of the 164 adolescents (incidence 25%, 95%CI 18.6- 32.4) that attended the private indoor event developed COVID-19. A sample was sequenced from one of the symptomatic and fully vaccinated individuals with BNT162b2 (Pfizer-BioNTech vaccine) finding SARS-CoV-2 Delta (B.1.617.2) variant of concern. The incidence of COVID-19 in the unvaccinated was 35.1% (95%CI 25.5-45.6), and in the vaccinated 11.4% (95%CI 5.1-21.3). There were more unvaccinated than vaccinated teenagers that developed COVID-19
A REFORMA DA EDUCAÇÃO PROFISSIONAL E TECNOLÓGICA NO BRASIL
Authors: Barbosa Pelissari Lucas
Published: November 2021

O objetivo do artigo é analisar os impactos, na Educação Profissional e Tecnológica (EPT), do atual processo de contrarreformas vivenciado pela educação brasileira. Nesse contexto, parte-se da hipótese segundo a qual a contrarreforma do Ensino Médio tem produzido transformações em outros campos da política educacional, inclusive a EPT, não se restringindo ao currículo da formação geral. Assume-se, como pressuposto teórico, o conceito de contrarreforma definido a partir da teoria política poulantziana. Do ponto de vista metodológico, foi delimitado, de início, um conjunto de mecanismos jurídico-políticos relacionados, simultamente, ao Ensino Médio e à EPT. Em seguida, por meio da técnica da Análise de Conteúdo, foram investigados documentos oficiais que embasam tais mecanismos, destacando-se os princípios de natureza político-pedagógica e curricular. Os objetos da análise são: a) Base Nacional Comum Curricular (BNCC) do Ensino Médio, expressa na Resolução CNE/CEB nº 17/2018; b) Programa Novos Caminhos, anunciado pelo governo federal em novembro de 2019; c) Diretrizes Curriculares Nacionais para a EPT (DCNEPT), aprovadas pela Resolução CNE/CP nº 01/2021. Como conclusão, defende-se a tese de que está em desenvolvimento, desde 2016, uma reforma da EPT brasileira. Essa reforma se construiu, até aqui, em três etapas, compreendidas cronologicamente entre os anos de 2016-2018, 2018-2021 e 2021 em diante. A ênfase dada à reforma da EPT tem o objetivo de caracterizá-la como um dos setores que compõem o quadro de contrarreformas neoliberais no Brasil atual, não estando, portanto, a educação profissional isenta de alterações mais profundas no conteúdo de suas políticas.

Aún se desconoce la etiopatogenia de la estomatitis aftosa, no obstante, existen algunos estudios que reportan un probable rol de la presencia de algunas comunidades microbianas en la alteración de la microbiota oral. En esta revisión sistemática (registro PROSPERO #CRD42021259427), evaluamos si los desequilibrios en la microbiota oral están asociadas con la estomatitis aftosa recurrente. A partir de estudios de casos y controles determinamos que la diversidad bacteriana no cambia notablemente en personas enfermas, sin embargo esos cambios son evidentes en términos de abundancia relativa como el aumento del género Prevotella y la disminución del género Streptococcus.
Structural and thermal performance of a novel form of cladding panel: the I-beam beetle elytron plate
Authors: Hu Liping , Zhang Zhijie , Chen Jinxiang , Ren Hao
Published: November 2021

To develop a non-bearing prefabricated straw sandwich concrete wallboard (I-beam beetle elytron plate: IBEPsc), the effect of certain structural parameters (e.g. panel thickness, T, number of I-cores, N, and core height, h) on mechanical and thermal insulation performance was investigated using the finite-element method, with the following results. (a) Bearing capacity of the IBEPsc is controlled by the maximum principal tensile stress; the optimal structural parameters of the IBEPsc for a self-insulated wall with a large safety margin are presented. (b) The consideration of strips as opposed to whole plates and the selected upper bearing constraint type have little influence on the mechanical properties. In practical applications, the strips and whole plates can be reasonably selected according to engineering needs, and these components can be connected with the main structure by conventional mortar. (c) According to qualitative analysis and comparison with common I-shaped thermal insulation walls, the IBEPsc requires the least material and weight while ensuring a sufficient safety margin in terms of mechanical and thermal insulation performance. Hence, biomimetic techniques can play a key role in breaking through the limitations of traditional structures. This paper can help direct the application of beetle elytron plates in prefabricated wallboards.

From Curriculum Demands to Genre Pedagogy: Bilingual Adaptation of Reading to Learn for an L2 Lesson Planning
Authors: Menco-Haeckermann Victor
Published: November 2021

Reading to Learn (R2L) is a literacy methodology and teacher development program inspired by Systemic Functional Linguistics. Recently, it has been adapted for second/foreign language courses with bilingual teaching (KARTIKA-NINGSIH; ROSE, 2021; RAMÍREZ, 2020; KARTIKA-NINGSIH, 2016). Although R2L has successfully expanded worldwide, its impact on textbooks, school programs, and educators has also been uneven. To describe how these conceptual inconsistencies play out, this article contrasts a textbook methodology partially informed by genre theory when applied in an L2 English class in Colombia with a recent bilingual adaptation of R2L in an L2 Spanish class in the United States. This latter case is based on genre theory and R2L pedagogy (ROSE, 2018a) and bilingualism approaches (RAMÍREZ, 2020; LESSOW-HURLEY, 2005; LABERGE; SAMUELS, 1974). Findings reveal a prominent pedagogical gap between the reading and the writing sections of the partially informed genre-based methodology but a robust linguistic scaffold in the bilingual R2L experience. The resulting recount exemplifies detailed and annotated lesson planning for teachers interested in thoroughly applying the latter methodology, especially for L2 settings. Preceded by some similar interventions, this experience confirms that the integration of both native and foreign languages within the R2L methodology makes it a promising approach.

The Titan_Illumina_PE workflow is a part of the Public Health Viral Genomics Titan series for SARS-CoV-2 genomic characterization. Titan_Illumina_PE was written specifically to process Illumina paired-end (PE) read data. Input reads are assumed to be the product of sequencing tiled PCR-amplicons designed for the SARS-CoV-2 genome. The most common read data analyzed by the Titan_Illumina_PE workflow are generated with the ARTIC V3 protocol. However, alternative primer schemes such as the QIAseq Primer Panel are also suitable for this workflow. The primer sequence coordinates of the PCR scheme utilized must be provided in BED format along with the raw Illumina read data. Upon initiating a Titan_Illumina_PE job, the input primer scheme coordinates and raw paired-end Illumina read data provided for each sample will be processed to perform consensus genome assembly, infer the quality of both raw read data and the generated consensus genome, and assign lineage or clade designations as outlined in the Titan_Illumina_PE data workflow diagram below.

Lack of staffs and language barriers are two factors that limit the Malay Heritage Museum UPM staffs to handle visitors especially during peak seasons. Therefore, an augmented reality mobile application is proposed to assists and entertain visitors while touring the museum. In this work, the augmented reality will be imposed at the Malay traditional cloth and textiles section. To develop the propose application, the methodology used in this work is agile model due to its capability to ensure that the overall process can be done within a time given and also its ability to increase the standard software instantly. Agile model consists of six phases such as requirements, design, development, testing, deployment and review. The experiment was conducted on the same day and three hours were allocated for the respondent because they were having classes. The time required for one respondent to experience the MTRACR is approximately 10 minutes per person. The survey is used as a platform to get feedbacks from users. Based on the survey, it shows that all users were satisfied with the proposed application and they suggested others to use it.
Learning Through Whatsapp During The Covid-19 Pandemic: A Case Study
Authors: Mheidly Nour
Published: November 2021

The COVID-19 pandemic forced lockdowns that severely affected the educational sector. The necessary shift to online learning was hindered in countries that lack communication technologies. In addition, the inadequate media and information literacy among educators and students alike exposed deficiencies in disaster preparedness. This resulted in the use of commonly used applications, such as WhatsApp, as a learning platform. We hereby present the learning experience of a mathematics class of the 10th grade through WhatsApp in a Lebanese public school. After analysis, we assess the initiative using the Rubric for eLearning Tool Evaluation. Although WhatsApp, as a learning tool, was functional, accessible, and technically effective, it hindered the learning experience with the lack of social, teaching, and cognitive presence. We offer our insights and recommendations on improving the learning and communication experience as we continue to navigate the current and any future pandemic.

Introduction. Although uncommon from a population-based perspective, there is considerable morbidity and mortality associated with malignant tumors of the nose and paranasal sinuses.

The objective of this study was to characterize the presentation, risk factors, management and survival of patients with these tumors treated at a single institution.

Materials and methods. We retrospectively reviewed the clinical records of patients with malignancies of the nose and paranasal sinuses diagnosed between January 2010 and December 2014 at a tertiary cancer center. Univariate and multivariate analysis were performed.

Results. Ninety patients were included in the study. Mean age at diagnosis was 62.8 years (range, 2–95 years) and mean follow-up was 44.5 months (range, 2–113 months). The maxillary sinus (33.3 %) and the nasal cavity (32.2 %) were the most frequent sites of origin. Squamous cell carcinoma (36.7 %), mucosal melanoma (15.6 %) and adenoid cystic carcinoma (10 %) were the most common histologic subtypes. Surgery was the primary treatment for 86.7 % of patients. Recurrence occurred in 45 patients (50 %). The overall 5‑year survival was 39.3 % and disease free-survival was 45.9 %. Survival was significantly decreased in non-smokers (p = 0.022), T3–4 tumors (p = 0.007), positive lymph nodes (p <0.001), nonepithelial tumors (p = 0.036) and positive margins (p = 0.032). Survival was not affected by surgical approach between endoscopic, open and combined approaches (p = 0.088).

Conclusion. Prognosis is poor, with high recurrences and low survival, but clearly histology, location and stage-dependent. Sound oncologic principles, with complete resections and negative margins, result in a better outcome.
iant extradural dermoid cyst in the right parietal-occipital region with obliteration of the transverse sinus
Authors: Belozerskikh K. A. , Evzikov G. Yu.
Published: November 2021

The study objective – to report a case of giant extradural dermoid cyst in a 48‑year-old woman; the cyst caused extensive erosion of the occipital bone and lower portions of the right parietal bone, which is quite rare.

Case report. A 48‑year-old female patient was admitted to the Department of Neurosurgery, A. Ya. Kozhevnikov Clinic of Nervous System Diseases, University Clinical Hospital No. 3, I. M . Sechenov First Moscow State Medical University on 28.07.2020. In 2002, the patient noted the emergence of a 1‑cm subcutaneous formation in the right occipital region. The formation was slowly growing. On 17.12.2015, she underwent magnetic resonance imaging of the brain. It revealed a 2,5 × 4,4 × 4,0 cm extradural formation with clear contours and erosion of the occipital and right parietal bones. On 12.03.2020, she had contrast-enhanced magnetic resonance imaging, which demonstrated that the tumor was growing (its size was 3,0 × 6,4 × 5,5 cm). Magnetic resonance imaging scans also showed extensive erosion (6,4 × 5,4 cm) of the occipital and right parietal bones and obliteration of the right transverse sinus. On 28.07.2020, the patient underwent elective surgery, namely excision of the extradural dermoid cyst in the right parietooccipital region with simultaneous reconstruction of the calvarial bones using a titanium plate. The cyst capsule and its contents were completely removed. The capsule was tightly attached to the dura mater, but did not invade it. To remove small fragments of the capsule that could potentially invade the bone, we performed small marginal resection of the calvarial bones at the depth of 2–3 mm from the defect margin. After the removal of cyst capsule, well-defined furrow could be visualized on the dura mater in the projection of the obliterated transverse sinus. Five days postoperatively, the patient was discharged from hospital in satisfactory condition.

Conclusion. Surgical treatment of extradural dermoid cysts implies radical removal of the tumor. Since the cyst capsule gets tightly attached to the edges of the bone defect along with bone erosion, the removal of such cysts as a single block is almost impossible. The risk of severe erosion of the skull bones caused by a dermoid cyst with extradural (and sometimes intradural) growth increases with age. Therefore, it is recommended to remove such tumors as early as possible. Patients with skull bone defects also require cranioplasty.

Published: November 2021

Introduction. Head and neck cancers are a significant healthcare and social problem worldwide with an estimated 377,713 new cases and 177,757 deaths registered annually. The incidence of head and neck cancer in Russia is 4.12 per 100,000. Despite all the achievements of current oncology, approximately 50–60 % of patients with locally advanced head and neck cancer develop relapses within the first 2 years after treatment completion.

The study objective is to analyze the effectiveness of regional intra-arterial polychemotherapy in the combined and comprehensive treatment of locally advanced oral cancer.

Materials and methods. This prospective study included 29 patients with oral squamous cell carcinoma treated and followed-up at N.N. Blokhin National Cancer Research Center between 2017 and 2020. The majority of patients (82.8 %) had stage III–IV disease. We evaluated clinical response to neoadjuvant regional intra-arterial chemotherapy, pathomorphosis of the primary tumor after surgery, treatment toxicity, overall survival, and relapse-free survival.

Results. The objective response rate assessed for the primary oral tumor after regional intra-arterial chemotherapy was 100 %; complete regression of the primary tumor was achieved in 82.8 % of patients. More than one-third of participants (35.5 %) had complete regression of metastases in regional lymph nodes. In 73.5 % of patients who had under gone neoadjuvant regional intra-arterial chemotherapy followed by surgery, we observed grade IV therapeutic pathomorphosis of the primary tumor. The 2-year relapse-free survival rate was 100 % in individuals with stage II–III disease and 92.9 ± 6.9 % in patients with stage IV disease.

Conclusion. The administration of regional intra-arterial chemotherapy as an induction stage ensures high treatment efficacy and high rate of complete pathomorphological responses. This suggests the opportunity of conservative treatment for patients with locally advanced oral cancer, which is currently considered impossible for such patients. Moreover, this method demonstrated moderate systemic toxicity, which expands the indications for its use and increase treatment compliance.
Personalized therapy with lenvatinib for progressive radioiodine refractory differentiated thyroid cancer in routine clinical practice

Published: November 2021

Among the differentiated forms of thyroid cancer, the least favorable clinical prognosis is observed in radioiodine-refractory differentiated thyroid cancer. The next step in the treatment of such patients is effective and potential toxicity multi-kinase inhibitors. Often, patients with refractory radioiodine thyroid cancer have a high tumor burden, various symptoms and comorbidity; therefore, clinicians may decide to initiate therapy at a reduced starting dose. In a randomized clinical multicenter study 211 higher objective response rate at 24th weeks were observed in the group of patients receiving lenvatinib at a dose of 24 mg per day compared with patients receiving Lenvatinib at a dose of 18 mg per day, while the difference in the incidence of serious adverse events grade 3–4 (SAE) at the 24th week of treatment were insignificant. Real clinical practice differs from randomized clinical trials regarding to the population of patients, their selection for treatment, adherence to drug dosage regimens, follow-ups, etc. In this paper, we analyzed the world and domestic clinical practice of the treatment of radioiod-refractory thyroid cancer and assessed the effect of the starting dose of lenvatinib and the duration of breaks in its administration on the effectiveness and safety of therapy.

Introduction. The associative role of the bacterial factor in the development of both primary malignant tumors of the oral mucosa and relapses is being actively discussed today. In the article published earlier, we have already described the possible mechanisms of action of periodontopathogenic microflora and its connection with the development of squamous cell carcinoma of the oral mucosa through cell proliferation, intracellular accumulation of pathogen, DNA replication and affect the signaling pathways of MARK (mitogen-activated protein kinase).

Objective – to analyze the impact of periodontal pathogens on the risk of oral squamous cell carcinoma and its recurrence, as well as to evaluate the role of polymerase chain reaction and bacterial culture in the diagnosis of squamous cell carcinoma.

Materials and methods. This study included 35 patients with stage Т3–4 squamous cell carcinoma, whose tumor tissue samples were tested for periodontal pathogens using culture and PCR. We analyzed 5 paraffin-embedded and 30 frozen tissue blocks from newly diagnosed (n = 15) and re-treatment (n = 15) patients.

Results. We found that PCR was more sensitive than culture for the detection of possible etiological agents and predictors of squamous cell carcinoma (including Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola) (р <0.001). For example, Tannerella forsythia and Treponema denticola were detected only using PCR, whereas all cultures were negative. However, conventional culture proved to be more effective than PCR for the detection of Prevotella intermedia. Between 3 % and 100 % of newly diagnosed patients tested positive for Treponema denticola and some other periodontal pathogens (PCR) developed relapses, whereas among re-treatment patients, this proportion was 66.6 %.

Conclusion. The combination of the culture method and the polymerase chain reaction method in the study of periodontopathogenic microflora has shown high efficiency in identifying possible predictors of squamous cell carcinoma of the oral mucosa and in preventing the development of chronic infectious periodontal diseases.

Criticism of “Bourgeois” Political Doctrines: Cognition through Denial
Authors: Kornev A. V.
Published: November 2021

In the historiography of political and legal doctrines, along with general scientific research methods, traditional methods are used: chronological, problematic, portrait, country studies. The critical approach is applied in all types of research of political ideas. Meanwhile, in historiography, this method is not given the attention it deserves. Criticism always involves an assessment of the empirical and theoretical material contained in various texts (sources). The productivity of this method is obvious. A critical approach makes it possible to assess the scientific content of a particular political doctrine, as well as the practical prospects for its implementation. Criticism implies a deep immersion of the researcher into the problem and maximum objectivity in evaluating the results obtained. This is what is most often lacking. The legal sphere is already political and is an integral part of it. Political doctrines, as well as the law (one of the forms of expression of law), are always connected with the interests of social groups (In the former terminology — classes). In this regard, it is not necessary to expect neutrality in the estimates. This was the case at the time of total administration in the field of social sciences, and it is happening today, when methodological pluralism and ideological diversity are declared. During the Soviet period, “bourgeois” doctrines and their creators were particularly criticized. As time has shown, this criticism was largely justified. History as such consistently confirms a curious pattern: “progressive” thinkers eventually become “reactionary”, as well as vice versa. Moreover, not only in our country. The paper states the dual orientation of criticism. On the one hand, a critical approach allows a more objective assessment of the political and legal doctrine. This shows its cognitive (cognitive) aspect. On the other hand, criticism gives the researcher a chance to convey to the reader the essence of any theory, doctrine, and idea and give him the opportunity to evaluate them himself. In the conditions of actual censorship, criticism remains almost the only genre of characterization of political and legal doctrines.
Using cloud computing to develop teaching self-learning competencies among the faculty members at Jouf University
Authors: Alanazy S. M.
Published: November 2021

Introduction. Cloud computing is a new model of computing based on network technology where computer-related technologies are provided as services that are permanently available for use. This technology saves faculty members’ time, and increases their interaction and communication with colleagues and students. Moreover, cloud computing solutions help faculty members finish and follow up all the required courses, in addition to allowing the faculty members to store and retrieve information comprehensively and immediately. As a result, using cloud computing provides practical, interactive solutions to deal with the academic tasks which a faculty member needs to perform his/her current academic work.

Aim. The current study aimed to uncover the reality of using cloud computing to develop the teaching competencies.

Methodology and research methods. The study relied on applying the survey method based on a descriptive approach using two types of questionnaire as the main tools for data collection. The sample of the study includes 48 faculty members and 103 students from the College of Education at Jouf University.

Results and scientific novelty. The results showed that self-assessment of using cloud computing to develop self-learning teaching competencies among faculty members is of a high level, while the teaching competencies for the application of cloud computing in self-directed learning among faculty members are of an average level according to their students. The results also demonstrated no significant relationship between these two main types of assessment.

Practical significance. The current study is significant in light of the fact that it facilitates to understand the impact of utilising cloud computing to accomplish proficient and educational abilities for faculty members at Jouf University.
Forced convection heat transfer with water and phase-change-material slurries
Authors:   , Choi Eunsoo , Cho Young I.
Published: November 2021

The objective of the present study was to understand the fundamental mechanism of the enhancement of the convective heat transfer coefficient as well as the thermal capacity of a working fluid by using the latent heat of the solid-liquid phase change of particles. Tests were performed with water flowing turbulently in a long heating test section (i.e., 627 diameters) with a uniform heat flux boundary condition. Three effects influence the local friction and heat transfer coefficients: (1) the developing effect, (2) the radial viscosity change effect, and (3) the axial viscosity change effect. A new analysis method to obtain fully developed friction factor and Nusselt number is proposed. The Blasius equation, f = 0.079 Re-0.25, was found to yield a good prediction of the turbulent friction coefficient with a 2.1% error. It would make a better prediction if the proportionality constant 0.079 in the equation was replaced with a new constant: 0.081. The power factor, m, in a general Nusselt number correlation, Nu = C Rem Pr0.4, was found to be 0.979, which was greater than the widely used value of 0.8 used in the Dittus-Boelter correlation. Tests were also conducted with a phase-change-material (PCM) slurry that was a suspension of PCM particles in a carrier fluid, water. A new method to generate very fine PCM particles using an emulsifier was introduced. With such fine PCM particles, the flow loop did not clog. Local pressure drops and local heat transfer coefficients were measured along the test section. Significant decreases in pressure drop occurred where the PCM particles in the slurry melted. The local convective heat transfer coefficient was found to vary significantly (up to 200%) when the particles melted. This made it difficult to directly apply the LMTD method or the effective thermal capacity method, which had been used in previous researches, to the heat transfer analysis of the PCM slurry flow. A new three-region melting model is proposed, and an explanation of the physical mechanism of the convective heat transfer enhancement due to the PCM particles is provided.

Angina bullosa hemorrhagica is one of the rare oral lesion which appears clinically as blood blisters within the oral cavity. This lesion may occur in response to any mild trauma to the oral tissue. It is an acute oral disease mainly seen at the lining mucosa. It is characterized by blood-filled ballooning of the oral mucosa in the form of vesicles and bullae. These lesions are single and rupture easily leaving an ulcerated area.

In this article the authors are describing the case of Angina Bullosa Hemorrhagica attended in Department of Periodontology at Hazaribag College of Dental Sciences & Hospital, Hazaribag.
Performance Analysis of PI, T1NFC, and T2NFC of Indirect Vector Control-Based Induction Motor Using DSpace-2812
Authors: Prasad Repana Ramanjan , Durgasukuamar Gadwala
Published: November 2021

A type 2 Neuro-Fuzzy torque controller for indirect vector control (IVC) based induction motor (IM) driving is presented in this work. In various operating modes, a linear fixed-gain proportional-integral (PI) based speed controller is employed in indirect vector control of an IM drive (IMD). To achieve high performance, the PI controller (PIC) requires precise and accurate gain parameters. The PIC gain values have been tuned for a specific operating point and may not perform satisfactorily when the load torque and operating point change. To enhance dynamic performance over a wide speed range and reduce load torque ripple, the PIC is replaced by a Type-1 neuro-fuzzy logic controller (T1NFC). The T1FLC is simple, easy to use, and successful at dealing with nonlinear control systems without the use of complex mathematical equations. Instead, it relies on simple logical rules that are decided by an expert. The T1NFC is replaced by a Type-2 neuro-fuzzy logic controller to enhance controller performance. Owing to the availability of three-dimensional control with type-reduction technique (i.e. Type-2 fuzzy sets and Type-2 reducer set) in the defuzzification process, the T2NFC effectively handles the large footprint of uncertainties compared to the T1NFC, whereas the T1NFC have only Type-1 fuzzy sets and a single membership function. The T2NFC using MATLAB Simulink is used to observe the induction motor performance characteristics like, stator phasor current, torque, and speed under various operating situations. T2NFC controllers provide better driving performance characteristics than PI and T1NFC controllers. When associated to the PI and T1NFC controllers, the suggested T2NFC greatly reduce the amount of ripple in the torque and stator current of the IM drive. Practical validation is also performed with a 3.7 KW IM drive and a DSP 2812 controller for real-time examination of the drive parameters.

Published: November 2021

In this paper, we propose a novel hybrid algorithm based on MAX-MIN Ant System version of ant colony optimization coupled with quadratic programming (MMAS-QP). Quadratic programming is used to optimize the Economic Dispatching process and MMAS for planning the switching schedule of a set of production units. The algorithm is implemented in MATLAB software environment for two systems, one is 4 generating units running for 8 hours, and the other is 10 generating units running for 24 hours. The impact of heuristic parameters on the behavior of the algorithm is highlighted through the parameters setting. Results obtained shows improved solution compared to several methods such as Modified Ant Colony Optimization (MACO), particle Swarm Optimization combined with Lagrange Relaxation (PSO-LR), Swarm and Evolutionary Computation (SEC), Particle Swarm Optimization combined with Genetic Algorithm (PSO-GA). The proposed method improves sufficiently the quality of the solution as well as the execution time.
Novel Hybrid Interval Type-2 Fuzzy Adaptive Backstepping Control for a Class of Uncertain Discrete-Time Nonlinear Systems
Authors: Boukhalfa Abdelouaheb , Khettab Khatir , Essounbouli Najib
Published: November 2021

A Novel hybrid backstepping interval type-2fuzzy adaptive control (HBT2AC) for uncertain discrete-time nonlinear systems is presented in this paper. The systems are assumed to be defined with the aid of discrete equations with nonlinear uncertainties which are considered as modeling errors and external unknown disturbances, and that the observed states are considered disturbed. The adaptive fuzzy type-2 controller is designed, where the fuzzy inference approach based on extended single-input rule modules (SIRMs) approximate the modeling errors, non-measurable states and adjustable parameters are estimated using derived weighted simplified least squares estimators (WSLS). We can prove that the states are bounded and the estimation errors stand in the neighborhood of zero. The efficiency of the approach is proved by simulation for which the root mean squares criteria are used which improves control performance.
