Authors: Joshi Nilesh V , Joshi Mridula , Rathod Varsha , Langde Deepak 
Published: March 2022

Introduction:
The aims of this study were 1) to find out the prevalence of occupational exposures to contaminated biological material among undergraduate students and interns; 2) to find out how many cases of occupational exposures to bloodborne pathogens are reported; and 3) to know the reasons for non-reporting of occupational exposures.

Materials and Methods:
The study was conducted in a Dental School in Navi-Mumbai, India. An anonymous self-administered questionnaire was formulated. 210 dental students were given a questionnaire out of which 150 students attending clinical postings in their third year, final year, and internship responded. Approval was obtained from the Institutional Ethical Committee.

Results:
The study revealed a very high prevalence (66.7%) of exposures among the students. Only 12% of the students reported the exposures to the staff. Students from III year and final year BDS (Bachelor of Dental Surgery) had mean exposure of 2.40 as compared to 1.94 among interns. 46% of the students stated that they did not report about the exposure because they thought that injury was of minor nature.

Conclusion:
There is a very high prevalence of occupational exposures among students which are not reported. There is a need for the development of a post exposure protocol which has to be strictly implemented. The principle of infection control has to be emphasised to the students periodically and they should be encouraged to report incidences of exposures to biological material.

Authors: Prusty Ajit K , Sharma Shivani , Malhotra Sumit 
Published: March 2022

Aim:
The aim of this 12 week, single-blind clinical trial was to compare the efficacy of Manual (Oral-B Pro Health Gum care®), Powered (Oral-B Cross action Power Dual®) and Charcoal (Colgate slim Soft Charcoal®) toothbrushes in plaque control.

Materials and Methods:
60 systemically healthy students were selected at random among the students of a Dental College, living under similar environment and dietary conditions. Plaque and calculus were removed professionally and three varieties of toothbrush were distributed among them. Plaque index (PI), sulcus bleeding index (SBI) and gingival index (GI) were assessed at baseline, 3, 6 and 12 weeks. Assessment of colony forming units (CFU) was done at baseline and 12th week. The learning effect over a period of time was also assessed.

Results:
Over the 12-week period, PI reduced significantly (P < 0.001) with % reduction in plaque from 47% to 59%, 41% to 53% and 45% to 55% for manual, powered and charcoal brush. A significant reduction in GI and SBI was also seen with all the brushes. An insignificant difference in PI, GI and SBI was seen between the brushes. CFU count before and after brushing reduced gradually and statistically significantly (P < 0.001) for all the brushes; however, by end of 12th week period, there was no significant difference (P > 0.05). The learning effect increased from 35% to 60%, 24% to 56% and 31% to 58% for three brushes, respectively, but was more pronounced for powered brush.

Conclusion:
It can be concluded that all the three brushes (manual, powered and charcoal) are clinically effective in removing plaque, with learning effect more pronounced for powered brush and if proper technique is followed, no brush is superior to the other.

Published: March 2022

Context:
Accuracy of fit of cast metal posts fabricated with direct and indirect techniques.

Aims:
To evaluate the accuracy of fit of cast metal posts fabricated with direct and indirect techniques using micro-CT.

Materials and Methods:
Sixty extracted human maxillary central incisors were used. The teeth were decoronated leaving 2 mm at the cementoenamel junction. Four patterns for each tooth were made including one direct and indirect wax pattern and one direct and indirect resin pattern. In total, 240 patterns and castings were made. Each tooth was scanned using microcomputed tomography (μCT) system with a resolution of 14.5 μm. μCT analyzer Sky scanner software was used to calculate the volume of space between the post and the canals. Statistical analysis used: The student paired t-test and unpaired t-test were used to determine the significant differences between groups.

Results:
The overall space between the canal walls and posts made with the direct wax and resin technique had an average mean value of 1.10 mm3, whereas with the indirect technique resin and wax pattern, the average mean was 1.30 mm3 which was significant.

Conclusion:
Within the limitations of the study, it was found that the accuracy of fit is better in direct technique using wax pattern.
Evaluation of Effect of Low Level Laser Therapy with Intracanal Medicament on Periapical Healing
Authors: Shah Deep , Ponappa Muckatira Cariappa , Ponnappa Kongettira Chittiappa 
Published: March 2022

Objective(s):
Photobiomodulation, also commonly referred to as low level laser therapy (LLLT), uses light energy to elicit biological responses from the cell and normalise cell function. Using LLLT on bone has been demonstrated to be effective in modulating inflammation, accelerating bone cell proliferation and enhancing the healing process. The objectives of this study were to evaluate postoperative pain and periapical healing in two different groups.

Materials and Methods:
40 subjects with periapical lesion were selected and were assigned randomly into two groups. Group I: Conventional root canal therapy along with LLLT. Group II: Conventional root canal therapy only. Radiographs were obtained and assessed at baseline, 3, 6 and 9 months postoperatively. The VAS pain scale was assessed post operatively at 0, 7th and 14th day respectively. The Independent t-test was used for evaluation of the data.

Results:
Significant differences were noted in reduction of periapicallesion at 3 and 9 months follow-up. The healing was better in Group I that received LLLT with the conventional Root Canal Treatment (RCT). Values for postoperative pain was lower in Group I than Group II, but were statistically non-significant.

Conclusion(s):
LLLT when used as an adjunct with conventional root canal treatment showed acceleration of the healing process of periapical lesions. LLLT has a positive effect on modulating the immune response for favourable healing.

Authors: Shenoi Pratima R. , Kokane Vandana B. , Thawale Himani V. , Kubde Rajesh R. , Gunwal Mohit K. , Shahu Shriya P. 
Published: March 2022

Context:
Class V cavity presents a clinical challenge in the field of restorative dentistry as the margin placement is partially in enamel and partly in cementum, and the trouble associated with this design is the microleakage at the tooth restoration interface.

Aims:
To evaluate and compare marginal microleakage in Class V cavities when restored with flowable composite and Cention-N restorative material.

Methods and Material:
This in-vitro study was performed on 30 human maxillary premolars, which were extracted for orthodontic reasons. Class V cavities were prepared on the buccal surfaces of each tooth. After application of seventh-generation bonding agent (3M ESPE, Single Bond Universal Adhesive), the teeth were divided into two groups of 15 each and restored with flowable composite (3M ESPE Filtek Z350 XT) and Cention-N (Ivoclar Vivadent) and were subjected to thermocycling. The teeth were then immersed in 0.1% Rhodamine B dye for 48 h. They were sectioned longitudinally into mesial and distal parts with the help of an isomet diamond saw. The sections were observed under a confocal laser scanning microscope (CLSM).

Statistical Analysis Used:
The results were subjected to statistical analysis using the Mann–Whitney U test and Pearson's Chi-square test.

Results:
The analysis showed statistically significant results among the groups. Cention-N showed lesser microleakage, which was statistically significant when compared to flowable composite (P = 0.005).

Conclusions:
Cention-N showed significantly lesser leakage and better adaptation than flowable composite.
Colonic polyps in Nigerians, a change in trends
Authors: Adegoke Omolade O. , Ajani Mustapha Akanji , Nwanji Ifeanyichukwu D. 
Published: March 2022

Background:Adenomatous polyps in the colon are recognized precursors of colorectal carcinoma; however, the low incidence of these polyps in sub-Saharan Africans has led many to believe that the pathway of colorectal cancer may differ in this region. The objective of this study was aimed to determine the change in trends of colonic polyps in Nigeria.Methods:This was a 10-year retrospective review of all colonic polyp specimens received at the Department of Pathology in our hospital utilizing the histopathology request cards and hematoxylin and eosin-stained slides. The data were analyzed using the IBM SPSS Statistics (version 23; IBM Corporation, Armonk, New York, USA).Results:A total of 131 cases were reviewed. The age of patients ranged from 5 to 86 years with a mean age of 55 years. The male-to-female ratio was 1.6:1. The mean age was 59.4 years. Of the 131 cases reviewed, 62 patients had adenomatous polyps, 49 had inflammatory polyps while 20 others included juvenile polyps, hyperplastic polyps, and hamartomatous polyps.Conclusion:Adenomatous polyps are increasingly being seen among Africans in the sub-Sahara region and perhaps they are not as rare as it was once thought provided the facilities for the diagnosis are available. They may yet play a more important role than has been ascribed to them in the pathogenesis of colorectal carcinomas in Africans.
Optimization of Hybrid Optical Amplifiers (Raman-EDFA) with a Standard Fiber (SMF) and a maximum pump power of 200mw in access networks: WDM-PON
Authors: Armel Bimogo , Dikoundou Essiben , Same Koko 
Published: March 2022

In this paper , we demonstrate the possibility of Raman -EDFA association in access networks. for this purpose, we evaluate the respective performances of these two types through a numerical method for 16 channels. Interesting results can be exploited; it is shown that with EDFAs, a target gain of 20dB can be reached for a wavelength range of 980 to 1440nm but with several perturbations in the received signal due to SNR and OSNR. These problems are solved with the integration of Raman amplification which pushes the gain limit to 27dB, with a better flatness.

Authors: Kuate Alain François , Tchueguem Paulin Nembot , Essiben Jean-François D. 
Published: March 2022

Purpose: This paper presents the design and analysis of rectangular patch antenna that can be reconfigured in frequency for the three non-overlapping channels of the 2.4 GHz Wi-Fi.
Methodology: To achieve this, a patch model in which four Pin diodes are introduced into the radiating structure, two operating in switching (ON / OFF) and two others kept blocked throughout operation has been proposed. By using as radiating element a copper hob placed on a substrate of the FR4_Epoxy type. The so-called CST Microwave Studio simulation software was used to simulate the design antenna.
Findings: It was shown that this rectangular patch antenna resonates at the center frequencies of channels 1 (2.412GHz); 6 (2.437 GHz) and 11 (2.462 GH) with an almost uniform radiation pattern for different diode configurations.
Recommendations: To improve the performance of this reconfigurable frequency patch antenna, future research must be based on optimizing the radiation parameters for configurations where one of the diodes is ON and the other is blocked.

Published: March 2022

Mucho ha cambiado desde que la transmisión y supervivencia del acervo culinario de los pueblos se limitaba al formato oral. Las distintas evoluciones tecnológicas han transformado no solo el qué comemos, sino también el cómo lo disfrutamos. Influenciando incluso los rituales de socialización de los alimentos. La gastronomía en República Dominicana ha evolucionado y esto se ha ido reflejando en el uso progresivo de innovadores formatos y plataformas de comunicación. Desde los “reality shows” en los que amateurs muestran su proeza en la cocina mientras se disputan ante las cámaras por la victoria, hasta quienes retocan el más mínimo detalle de los alimentos, como si se tratara de supermodelos. Aquellos que han elegido el camino de las artes culinarias como profesión cuentan con nuevos aliados. Tecnologías y perfiles antes inexistentes que narran la historia de recetas, la experiencia de su consumo y hasta la proveniencia de sus ingredientes. Entre ellos encontramos categorías como food stylists, que resaltan la esencia de los platos, y foodies que se dan a la labor de salir de aventuras en búsqueda de magníficas creaciones. El presente documento evalúa algunos de los sujetos que se van abriendo camino en estas áreas. A través de un análisis de la literatura existente se pretende iniciar la identificación de perfiles digitales, abanderados y embajadores de la gastronomía que, más allá de los fogones, se encuentran detrás de los dispositivos y que con su labor engrandecen la calidad culinaria de la República Dominicana.
REFLEXIONES EN TORNO A LA REVALORIZACIÓN DEL PATRIMONIO ALIMENTARIO MARÍTIMO PESQUERO DE MALLORCA: LA EXPOSICIÓN TEMPORAL “DEL MAR A LA TAULA”.
Authors: Borras Rhodes Diana Roberta , Cifre Borràs Joana 
Published: March 2022

En este trabajo ofrecemos una reflexión sobre los procesos de patrimonilización del patrimonio inmaterial relacionado con el pescado analizando para ello la propuesta expositiva realizada en torno a la cultura alimentaria marítimo pesquera de Mallorca y en la que hemos participado activamente. La reflexión toma en consideración algunas aportaciones de la antropología, las acciones investigativas que fundamentan la propuesta expositiva así como su estructura y contenido, que se expone brevemente. El análisis nos permite poner de manifiesto el interes de tomar en consideración los presupeuestos de la antropología cultural aplicada al conocimiento de las culturras alimentarias así como la necesidad de abordar la complejidad de los fenómenos alimentarios, incluyendo la dimensión temporal, la memoria oral y las situaciones actuales. Se analiza también el interés de las propuestas expositivas temporales como instrumento que permite superar algunas de las contradicciones que caracterizan a los procesos patrimonializadores de la cultura alimentaria.Estructurada en once paneles la exposición presenta la cultura alimentaria asociada a la actividad pesquera artesanal desde el punto de vista de aquellos que le han dedicado su vida. Dicha información fue recogida mediante entrevistas en profundidad con pescadores y sus mujeres, las pescaderas, con un panel de expertos formado por diferentes cocineros célebres en la isla y con análisis de fuentes secundarias. Así, la tradición del mar y la pesca y sus evoluciones se presentan en temas que varían desde la vida a bordo y el trabajo en el mar, hasta las recetas de pescado del ámbito domèstico, la preparación y conservación del mismo y la importancia de la restauración y de los recetarios como instrumentos de recreación y transmisión de saberes.
Extrapolating continuous vegetation water content to understand sub-daily backscatter variations

Abstract. Microwave observations are sensitive to vegetation water content (VWC). Consequently, the increasing temporal and spatial resolution of spaceborne microwave observations creates a unique opportunity to study vegetation water dynamics and its role in the diurnal water cycle. However, we currently have a limited understanding of sub-daily variations in the VWC and how they affect microwave observations. This is partly due to the challenges associated with measuring internal VWC for validation, particularly non-destructively, and at timescales of less than a day. In this study, we aimed to (1) use field sensors to reconstruct diurnal and continuous records of internal VWC of corn and (2) use these records to interpret the sub-daily behaviour of a 10 d time series of polarimetric L-band backscatter with high temporal resolution. Sub-daily variations in internal VWC were calculated based on the cumulative difference between estimated transpiration and sap flow rates at the base of the stems. Destructive samples were used to constrain the estimates and for validation. The inclusion of continuous surface canopy water estimates (dew or interception) and surface soil moisture allowed us to attribute hour-to-hour backscatter dynamics either to internal VWC, surface canopy water, or soil moisture variations. Our results showed that internal VWC varied by 10 %–20 % during the day in non-stressed conditions, and the effect on backscatter was significant. Diurnal variations in internal VWC and nocturnal dew formation affected vertically polarized backscatter most. Moreover, multiple linear regression suggested that the diurnal cycle of VWC on a typical dry day leads to a 2 (HH, horizontally, and cross-polarized) to almost 4 (VV, vertically, polarized) times higher diurnal backscatter variation than the soil moisture drydown does. These results demonstrate that radar observations have the potential to provide unprecedented insight into the role of vegetation water dynamics in land–atmosphere interactions at sub-daily timescales.

O artigo reflete sobre os aspectos referentes aos problemas de aprendizagem junto à prática do professor, onde este se sente desafiado a repensar a prática pedagógica, inscrevendo a possibilidade de novos procedimentos. O uso das tecnologias ainda se apresenta como um desafio para muitos professores no desenvolvimento do trabalho docente. Questionamentos e reflexões sobre quais são os reais potenciais educativos das tecnologias para o processo ensino e aprendizagem, e de que forma elas podem influenciar as ações pedagógicas, estão presentes nas pesquisas educacionais. O artigo discute o uso das novas tecnologias no processo de ensino-aprendizagem no âmbito escolar. A partir de pesquisa bibliográfica, verifica-se a inserção das tecnologias, compreendendo os impactos da sua utilização nas atividades de professores e na apropriação pelos alunos. O objetivo do artigo busca analisar possíveis dificuldades encontradas por docentes e discentes a partir da utilização das tecnologias no processo educativo. Para sustentar as hipóteses levantadas procurou-se respaldo teórico em bibliografia especializada. A escolha do tema teve como intuito investigar quais dificuldades há na inserção das tecnologias nos espaços escolares e como irão se comportar os alunos na cultura digital em tempos de pandemia. As dificuldades de aprendizagem têm causas variadas. Entretanto, parte -se do pressuposto de que as dificuldades dos discentes em utilizar as tecnologias poderiam ser minimizadas se escolas e professores estivessem preparados para lidar com tal situação. Desta forma, entende-se que esta pesquisa possa contribuir de maneira para a reflexão de educadores preocupados com o desempenho dos educandos.
