Authors: Silva Ranilza Francisca da , Alves Silvia Leticia Louzeiro 
Published: July 2021

RESUMO:O anúncio da pandemia no Brasil em março de 2020, o isolamento social para conter a contaminação pelo Covid-19 promoveram a redefinição de espaços e práticas de ensino. As aulas nas escolas começaram a acontecer virtualmente, o ensino remoto tornou-se uma realidade que transformou as casas em sala de aula. Com o atual cenário educacional, o espaço-tempo da escola foi ressignificado, exigiu novo olhar e inquietação sobre como e o quê ensinar. Os professores tiveram que se reinventar e ressignificar suas práticas. Essa realidade chama atenção e merece ser interrogada, especialmente quando levamos em conta o trabalho remoto do professor de língua portuguesa. Nesse sentido, essa pesquisa tem o objetivo de investigar a mediação e a interação do professor por meio da utilização do livro didático de português para o ensino fundamental em tempos de pandemia e ensino remoto. Delimitamos como corpus, aulas de português gravadas. Na análise, levamos em conta o uso do livro didático que a professora utiliza como prática pedagógica dessa mediação. Na análise pautou-se nas contribuições dos autores Geraldi (1997; 2010;2011;2020), Antunes (2003). Os documentos oficiais os PCN de Língua Portuguesa (1998). As práticas pedagógicas do professor nos permitem refletir sobre o uso do livro didático que foi produzido para trabalhar de forma presencial, porém vai para o ensino remoto, e o professor cria possibilidades de trabalhar a leitura e a escrita de forma significativa.Palavras-chave: aula de português; livro didático; ensino remoto; leitura; escrita

Authors: Da Silva Joel Dias , Andrade Michelle de 
Published: July 2021

Este estudo foi desenvolvido com objetivo de demonstrar a viabilidade da reciclagem dos efluentes tratados para o processo de tingimento sintético sem alterar a qualidade do produto final, tornando assim uma ferramenta de gestão e desenvolvimento sustentável para a empresa. Para isso, realizou-se a avaliação do histórico de parâmetros físico-químicos, o percentual de reciclagem de efluentes/dia em um ano assim como os respectivos resultados de testes de sublimação do fio que garantem a qualidade do tingimento. Realizado esse levantamento pode-se definir o percentual de efluentes/dia a ser reciclado no processo de tingimento, do qual em média constatou-se que 30% dos efluentes gerados na produção, após passar por um tratamento via físico-químico, retornou ao processo. Para se garantir a qualidade do produto final, comparou-se um processo padrão com um processo que reciclou 30% dos efluentes tratados, por meio da realização de testes de sublimação do fio e resultados de análises dos efluentes. Os resultados foram satisfatórios, não demonstrando nenhuma alteração na qualidade do
tingimento.

Evaluation of geothermal potential in some parts of Bida Basin of Nigeria using Curie point depths and heat flow from spectral analysis of aeromagnetic data.
Authors: Tsepav Matthew Tersoo , Mallam Abu 
Published: July 2021

The Centroid method of Spectral Depth analysis was used to evaluate the Curie point depth (CPD), Geothermal Gradient and Heat Flow in some parts of the Bida Basin of Nigeria with a view to determining the energy potential of the area. The reduced-to-pole aeromagnetic data was divided into 16 overlapping ensembles and Fast Fourier Transformed to decompose the anomalies into their energy and wavenumber components using Oasis montaj software. The radial power spectrum was calculated for each of the grid points with the locations of the centres of the ensembles and a plot of Energy spectrum versus frequency was carried out to generate two different gradients: s<sub>1</sub> and s<sub>2</sub> representing different depth source models. These gradients were used to evaluate the average depth to the top of the deepest crustal block, Z<sub>t</sub>, depth to the centroid of the deepest crustal block, Z<sub>0</sub>, CPD, Geothermal Gradient and Heat flow. From the results obtained, the CPD varied from 2.59 to 8.23 Km while the thermal gradient and heat flow in the area revealed values ranging from 70.45 to 224.15 <sup>o</sup>CKm<sup>-1</sup> and 176.13 to 560.37mWm<sup>-2 </sup>respectively. The results of the contouring in conjunction with the CPD, geothermal gradient and the heat flow values have shown that the area has a greater energy potential in the south-eastern block of Katonkarfi, with shallow CPD and high geothermal gradient and heat flow. These results could be incorporated in the GIS and available geological, geophysical and geochemical information of the area to facilitate selection of the optimum site for energy exploration.
Bilateral Distal Radius Fractures in a Patient with Osteogenesis Imperfecta
Authors: Freedman Jonathan D. , Merkle Alexander N. , Iorio Matthew L. 
Published: July 2021

Case:
Longitudinal follow-up of a 53-year-old woman with osteogenesis imperfecta (OI) Type III and concurrent bilateral distal radius fractures is reported. She had a right-sided displaced fracture and a left-sided minimally displaced fracture. Operative management of the displaced fracture showed adequate healing in 10 weeks. The minimally displaced fracture failed nonoperative management but did adequately heal after operative intervention.

Conclusion:
Early surgical intervention of distal radius fractures may be considered in patients with severe OI, even in fractures with minimal displacement. This is likely particularly important with patients who are heavily reliant on their upper extremities for mobility.

Published: July 2021

Case:
We report a rare case of femoral-sided avulsion fracture of both the anteromedial and posterolateral bundle attachments of the anterior cruciate ligament (ACL). We performed an arthroscopic double-bundle pull-out repair. At the 1-year follow-up, the patient had no deformity, laxity of the knee, and no limitations when engaging in various sports activities.

Conclusion:
An avulsion fracture of both the anteromedial and posterolateral bundle attachments is a rare injury. Arthroscopically assisted reduction and fixation demonstrated successful achievement of both bone union and good ACL function.
Ultrasound study of layer-specific strain and perfusion of left ventricular myocardium in patients with dilated cardiomyopathy
Authors: Tang Sha , Guan Lina , Mu Yuming 
Published: July 2021

Abstract
Purpose

To investigate the changes in deformation and myocardial microcirculation perfusion of left ventricular three-layer myocardium in patients with dilated cardiomyopathy (DCM) by using speckle tracking imaging (STI) and myocardial contrast echocardiography (MCE).
Methods

Twenty-four patients with DCM and 19 healthy controls were selected. Two-dimensional and MCE dynamic images of apical four-chamber, two-chamber, and three-chamber sections and left ventricular mitral valve, papillary muscle and apex sections were collected. The peak values of longitudinal strain (LS), circumferential strain (CS), cross-sectional area of a microvessel (A) and average myocardial microvascular lesion (β) were obtained by Qlab 10.8 workstation values, and myocardial blood flow (MBF) was calculated with A × β to evaluate the deformation and coronary microvascular perfusion of left ventricular three-layer myocardium.
Results

The brain natriuretic peptide (BNP), left ventricular mass index (LVMI), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVEDS), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left atrial volume index (LAVI), E peak in early diastolic period/A peak velocity in late diastolic period (E/A) and average E/e' in the DCM group were higher than those in the control group (P < 0.05); left ventricular ejection fraction (LVEF), left ventricular fractional shortening (FS) rate, stroke volume (SV), cardiac output (CO), cardiac index (CI), A peak, and the e' and a' velocities of both the lateral wall and interventricular septum were smaller than those in the control group (P < 0.05). The LS, CS, A, β, and A × β of the DCM group were all lower than those of the control group, The time to peak and the cardiac cycle required to reach the peak were longer than those in the control group (P < 0.05). The pattern of myocardial strain and perfusion among myocardial layers was subendocardial > middle > subepicardial. The correlation coefficients of LS with A, β, and A × β were − 0.500, -0.279 and − 0.190, respectively, and the correlation coefficients of CS with A, β, and A × β were − 0.383, -0.255 and − 0.208, respectively.
Conclusions

The deformation of the three-layer myocardium and coronary microcirculation perfusion in DCM patients were diffusely damaged from the endocardium to the epicardium, layer by layer. The longitudinal function of the left ventricular myocardium was closely related to changes in myocardial microcirculation perfusion. Echocardiography is helpful to evaluate myocardial blood flow and myocardial ischemia in patients with DCM.
Prediction of flyrock throw distance in quarries by variable selection procedures and ANFIS modelling technique
Authors: Hudaverdi Turker 
Published: July 2021

Abstract
This study suggests application of variable reduction procedures for flyrock prediction. It was aimed to create robust and non-complex predictive models. Eleven operational blast parameters and rock mass properties were measured in an aggregate quarry. Dominant parameters for flyrock occurrence were determined by multivariate statistical methods. Two parallel ANFIS models were developed for flyrock prediction. The first ANFIS model was constructed based on the results of stepwise regression. Burden-hole diameter ratio, in-situ block size and specific charge are the input parameters of ANFIS 1. The second ANFIS model was created based on the results obtained by factor analysis. Burden-hole diameter ratio, bench height- burden ratio, number of holes and charge weight are used as input parameters for ANFIS 2. The calculated mean absolute percentage errors are lower than eight percent for the ANFIS predictions. The median absolute errors are lower than 5 meters. The study also investigates alternative accuracy measures to evaluate forecasting performance. Standardized errors, normalized errors and Nash–Sutcliffe Efficiency (NSE) were found to be useful for model validation. It is concluded that more than a single model can be created for a specific site. Pre-statistical analysis for variable reduction increases performance of the predictive models. Burden appeared to be a significant parameter for flyrock throw.

Abstract
Objective

To evaluate the efficacy and toxicity of SBRT for localized prostate cancer (PCa). Moreover, it is the largest-to-date pilot study to report 5-year outcomes of SBRT for localized PCa from China.
Methods

In this retrospective study, 133 PCa patients in our center were treated by SBRT with CyberKnife (Accuray) from October 2012 to July 2019. Follow-up was performed every 3 months for evaluations of efficacy and toxicity. Biochemical progression-free survival (bPFS) and toxicities were assessed using the Phoenix definition and the Common Terminology Criteria for Adverse Events (CTCAE) v.5.0 respectively. Factors predictive of bPFS were identified with COX regression analysis.
Results

133 patients (10 low-, 21 favorable intermediate-, 31 unfavorable intermediate-, 45 high-, and 26 very high risk cases on the basis of the NCCN risk classification) with a median age of 76 years (range: 54–87 years) received SBRT. The median dose was 36.25Gy (range: 34-37.5Gy) in 5 fractions. Median follow-up time was 57.7 months (3.5–97.2 months). The overall 5-year bPFS rate was 83.6% for all patients. The 5-year bPFS rate of patients with low-, favorable intermediate-, unfavorable intermediate-, high-, and very high risk PCa was 87.5%, 95.2%, 90.5%, 86.3%, and 61.6% respectively. Urinary symptoms were all alleviated after SBRT. All the patients tolerated SBRT with only 1 (0.8%) and 1 (0.8%) patient reporting grade-3 acute and late genitourinary (GU) toxicity, respectively. There were no grade 4 toxicities. Gleason score (P < 0.001, HR = 7.483, 95%CI: 2.686–20.846) was the independent predictor of bPFS rate after multivariate analysis
Conclusion

SBRT is an efficient and safe treatment modality for localized PCa with high 5-year bPFS rates and acceptable toxicities.
On induced map f# in fuzzy set theory and its applications to fuzzy continuity
Authors: Kaur Sandeep , Goyal Nitakshi 
Published: July 2021

Abstract
In this paper, we introduce # image of a fuzzy set which gives a induced map f # corresponding to any function f : X → Y , where X and Y are crisp sets. With this, we present a new vision of studying fuzzy continuous mappings in fuzzy topological spaces where fuzzy continuity explains the term of closeness in the mathematical models. We also define the concept of fuzzy saturated sets which helps us to prove some new characterizations of fuzzy continuous mappings in terms of interior operator rather than closure operator.
Weaning and Extubation Assisted with Conversational Hypnosis : A Systematic Review
Authors: Wormser Johan , Romanet Christophe , Bellaïche Aurel , Philippart François 
Published: July 2021

Abstract
Background : Patients admitted in intensive care units often receive mechanical ventilation. Prior to extubation, weaning process could be a major cause of dyspnea and anxiety in awake intubated patients. Hypnosis is commonly used to manage anxiety and pain. Our hypothesis is that hypnosis would decrease stress during the weaning and extubation process. Methods: This systematic review follows PRISMA Guidelines and was registered in PROSPERO (CRD42020171445). Web of Science, MEDLINE and Cochrane Central Register of Controlled Trials databases were searched until 11 March 2020. We included all interventional trials assessing hypnotherapy for intubated patients whom were undergoing weaning or extubation. Two of the authors independently screened studies, extracted data and assessed risk of bias from identified trials. Results: One study fulfilled our selection. This case series included 2 patients. Eleven sessions were completed. Dyspnea was not assessed/reported. Hypnotherapy decreased anxiety during the weaning process from a median of 1 point (Interquartile Range: 1.0-2.5). Increase in oxygen saturation is also reported. There was no evidence of neither an anxiety reduction or an oxygen saturation improvement. This is due to the scarcity of publication and the methodological design of the one selected study. Conclusions: We cannot conclude whether or not hypnosis could be recommended in the weaning process of intubated patients. Further studies are needed to assess hypnosis effects. Registration: The present systematic review was registered in the International prospective register of systematic reviews (PROSPERO) under registration number CRD42020171445.

Published: July 2021

Abstract
Rivers in urban environments are significant components of their ecosystems but remain under threat of pollution from unchecked discharges of industrial sewage and domestic wastewater. Such river pollution, particularly over the longer term involving heavy metals, is an issue of worldwide concern regarding risks to the ecological environment and human health. In this study, we investigate the long-term pollution characteristics of the Huafei River, an important urban river in Kaifeng, China. River sedimentary samples were analyzed, assessing the degree and ecological risk of heavy metal pollution using the geo-accumulation index and potential ecological risk index methods; whilst Pearson’s correlation, principal component, and cluster analyses were used to identify the sources of pollution. The results show that heavy metal concentrations are significantly higher than their corresponding fluvo-aquic soil background values in China, and the geo-accumulation indexes indicate, that of the 8 heavy metals identified, Hg is most prevalent, followed in sequence by Cd > Zn > Cu > Pb > Ni > As > Cr. The potential ecological risk index of the Huafei river is very high, with the potential ecological risk intensity highest in the midstream and downstream sections where it is recommended that pollution control is carried out, especially concerning Hg and Cd. Long-term sequence analysis indicates that Cu and Pb dropped sharply from 1998 to 2017, but rebounded in 2019, and that Zn shows a continuous decreasing trend. Four main sources for the heavy metal contaminants were identified: Cr, Cu, Ni, Pb, Zn and Hg derived mainly from industrial activities, traffic sources and natural sources; Cd originated mainly from industrial and agricultural activities; whilst As was mainly associated with industrial activities. It is anticipated that the findings of this study will provide theoretical references for the effective control and scientific management of heavy metal pollution in the Huafei River and its surrounding areas.
Fuzzy Decision-Making Soft Model for Family Financial Planning in The Post COVID-19 World
Authors: SUN Chia-Chi 
Published: July 2021

Abstract
With COVID-19 making headlines around the world, it is normal to feel uncertain about many aspects of life right now, including family financial planning and wealth management. With the increase in family wealth and the size of organizations, there is a comparable increase in their assets. There is considerable demand for professionals to manage these assets and coordinate investment activities in order to maintain growth. The issue arises of how to increase a wealth management bank’s competitive advantages by segmenting a set of the selection criteria for a wealth management bank to effectively manage personal wealth. The results showed that the management’s learning and growth perspective was the most important causal dimension of wealth management bank selection. This paper also draws on the research results for managerial practice implications.

Abstract
Purpose

The Rheumatoid Arthritis Flare Questionnaire (RA-FQ) is a patient-reported measure of disease activity in RA. We estimated minimal and meaningful change from the perspective of RA patients, physicians, and using a disease activity index.

Methods

Data were from 3- and 6-month visits of adults with early RA enrolled in the Canadian Early Arthritis Cohort. Participants completed the RA-FQ, the Patient Global Assessment of RA, and Patient Global Change Impression at consecutive visits. Rheumatologists recorded joint counts and MD Global. Clinical Disease Activity Index (CDAI) scores were computed. We compared mean RA-FQ change across categories using patients, physicians, and CDAI anchors.

Results

The 808 adults were mostly white (84%) women (71%) with a mean age of 55 and moderate-high disease activity (85%) at enrollment. At V2, 79% of patients classified their RA as changed; 59% were better and 20% were worse. Patients reporting they were a lot worse had a mean RA-FQ increase of 8.9 points whereas those who were a lot better had a -6.0 decrease. Minimal worsening and improvement were associated with a mean 4.7 and -1.8 change in RA-FQ, respectively, while patients rating their RA unchanged had stable scores. Physician and CDAI classified more patients as worse than patients, and minimal and meaningful RA-FQ thresholds differed by group.

Conclusion

Thresholds to identify meaningful change vary by anchor used. These data offer new evidence demonstrating robust psychometric properties of the RA-FQ and offer guidance about improvement or worsening, supporting its use in RA care, research and decision-making.
