Published: July 2021

Background:
Continuing Medical education during the COVID-19 Pandemic has been a great challenge to Medical educators, especially teaching clinical skills online.

Aims:
The study aims too study the efficacy of teaching ECG in online mode to first MBBS students in the Department of Physiology.

Materials and Methods:
There are 200 students in the first MBBS batch at Burdwan Medical College. Our method of teaching was flipped classroom-assisted self-directed learning. For teaching ECG to our students we had first arranged for presession MCQ to assess the initial level of knowledge. We had then provided the students with PowerPoint presentations with voice narrations for their self-study, following which the students were divided into batches of twenty and each batch had a team leader and a facilitator. These small batches were shown videos of instruments, methods of recording ECG, normal and abnormal ECG along with explanations in multiple sessions (10). Doubt clearing sessions were arranged for each batch and these sessions were brainstorming. The students were assessed with MCQs (10 marks each Session), oral questions, short answer type questions, spots, and problem-based questions. We also took a feedback survey from the students and provided the students with feedback regarding their performance.

Results:
MCQ assessments of students in Pre and Posttest session on ECG teaching classes were 50.39 ± 19.41 vs. 65.25 ± 9.14; P ≤ 0.001**. Students performed significantly better in MCQ assessments of students on Normal parameters of ECG assessment as compared to Abnormal ECG parameters: 67.25 ± 10.98 vs. 63.157 ± 7.399; P = 0.000424**. Results of Written Examination and Viva Examination of students in ECG classes were 64.844 ± 9.923 vs. 71.89 ± 10.49; P ≤ 0.001**.

Conclusions:
The online method of teaching ECG was a success in the institution as observed in this study as observed in the assessment. Students performed better in viva in online exam for ECG and students were satisfied with online delivery.
Musicology went Pop: Raziskovanje globalnih glasbenih tokov skozi prizmo nacionalnih šol in drugih znanstvenih konvencij

Prav tako kot v ZDA in Veliki Britaniji je bil tudi v Zvezni republiki Nemčiji eden od prvih pristopov k raziskovanju popularne glasbe sociološki. Nadaljnji impulzi so prihajali s področja glasbene pedagogike. V okviru nemške znanstvene organizacije z imenom Arbeitskreis Studium Populärer Musik e.V. se je akademski diskurz o popularni glasbi sprva naslonil na sistematično muzikologijo, nato pa je pričel upoštevati tudi izsledke sorodnih disciplin, med njimi sociologije, etnologije, antropologije, »cultural studies« in »gender studies«. S tem se je odprl nov zorni kot približevanja glasbenim fenomenom, ki skuša ujeti v smiselne aksiome predvsem kompleksnost in polivalentnost glasbenih procesov. Na osnovi teh izkušenj prestavlja za avtorico osnovni predmet muzikološkega raziskovanja glasbeno življenje kot živ in nenehno se spreminjajoč organizem. Zavzema se za celostni pristop k raziskovalni materiji, metodološki pluralizem, interdisciplinarnost raziskovanja, iskanje dialoga z drugimi znanstvenimi panogami ter vodenje konstruktivnega diskurza med različnimi pogledi, ·šolami in teoretskimi pozicijami.

La estética de la música y la belleza de la trova, se vio reflejada en la actividad de disertación académico-musical que se realizó en el Doctorado en Investigación en Educación, el sábado 1 de mayo del año 2021; con el Cantor y Trovador Otto Mora, quien inició expresando que el arte integra la música como una manifestación que proporciona una experiencia estética que motiva la percepción individual, la creatividad y estimula los sentimientos, los pensamientos y las ideas. Gracias a los aspectos personales de tipo emocional, lo cual permite descubrir la estética de la obra. Entre los elementos estéticos musicales están la armonía y la emotividad, que están inmersos en la estética y las relaciones entre complejidad y estética, que conocen de diversidad, de transformaciones, de transiciones, de emergencia, de impredecibilidad y de autoorganización. Y el pensamiento sistémico, que nos plantea el concepto de propiedades emergentes de los sistemas como el calor, la sinergia y la buena vibra; aseguró Mora que la música es una propiedad emergente del sistema que la produce.

Published: July 2021

A educação superior a distância no Brasil tem sido desafiada a integrar esse novo processo educativo com um corpo de profissionais da educação, entre eles o tutor presencial e o tutor a distância. Neste trabalho se discute sobre o tutor a distância, objetiva-se avaliar os saberes da mediação online do tutor a distância na educação superior semipresencial. A relevância deste estudo se reporta a necessidade que se tem em avaliar o trabalho do tutor durante e após a sua atuação e no que precisa melhorar. O tutor a distância com uso de ferramentas e artefatos realiza a mediação online da aprendizagem do aluno através do ambiente virtual de aprendizagem. Indaga-se, portanto que saberes o tutor a distância precisa se apropriar para realizar esse trabalho educativo na educação semipresencial? A pesquisa com natureza transversal e descritiva, os dados tiveram uma abordagem quantitativa. Desenvolvida a partir do referencial teórico em relação aos saberes atitudinais, conceituais e procedimentais (COLL,1998). Observou-se que a pesquisa apresentou no modelo final fornecido pela regressão múltipla e comparando-se os coeficientes padronizados β, na dimensão conceitual maior peso na composição da nota da escala de avaliação (β = 0,529), entendeu-se que os saberes conceituais estão bem representados na avaliação dos alunos para com os tutores. Quanto ao saber atitudinal atingiu a um patamar de (β = 0,319), sinalizou a uma linha mediana entre os saberes, o que se concebe que o grau de motivação se encontra acima da média em relação aos resultados dos saberes conceituais. O saber procedimental apresentou-se abaixo da média que o saber conceitual, a um nível de (β=0,233). Os resultados apontaram que este nível revela que apesar de o tutor receber tudo pronto, as metodologias e estratégias didáticas devem ser mais intensificadas, pois precisa mediar no que concerne a linguagem adequada, presença social online mais intensificada no ambiente virtual de aprendizagem, atividades de aprendizagens direcionadas e atividades de avaliação diagnósticas, formativas e contínuas que regulem a aprendizagem do aluno.
O Novo Ensino Médio: a disputa em torno de um velho projeto formativo
Authors: Ribeiro de Souza Fernanda 
Published: July 2021

Este artigo apresenta uma análise a respeito do processo de disputas que se configura em torno do projeto formativo do Novo Ensino Médio. Desenvolvido por meio de pesquisa bibliográfica e análise documental, retoma as perspectivas formativas expressas pelos documentos que configuraram as propostas de formação para o Ensino Médio a partir da década de 1990. Aborda, sobretudo, os princípios presentes na Reforma do Ensino Médio, instituída pela Lei no 13.415/2017, na nova Base Nacional Comum Curricular e nas Diretrizes Curriculares Nacionais para o Ensino Médio, aprovadas em 2018. Constatou-se que a proposta do Novo Ensino Médio é marcada pelo retorno à centralidade curricular com base em competências e está submissa aos processos de reestruturação do capital, marcados pela retomada radical do neoliberalismo, assemelhando-se ao movimento ocorrido nos anos de 1990. Retoma, portanto, um velho projeto formativo, acentuando o caráter dualista da formação proposta para o Ensino Médio.

Published: July 2021

After a period of use in the oral cavity the bond between denture base and soft denture liner weaken or fails creating a suitable environment for fungal colonization. Traditional medical plants that have antifungal agents are considered more safe and with few side effects. The objective of this study was to evaluate the effect of oil and ethanol extracts of Artemisia aerial parts on Candida albicans growth and shear bond strength of soft denture liner. Candida albicans species were isolated and diagnosed, oil and ethanol extracts of Artemisia were prepared, the effect of the extracts on Candida albicans were tested by agar well diffusion test and micro dilution test. Finally, 30 specimens of soft denture liner were prepared for testing shear bond strength by Universal Instron machine before and after incorporation of the extracts. The results showed that all the concentrations of oil extract inhibit the growth of Candida albicans except (12.5 mg/ml) and there were significant differences (P≤0.05) between all concentrations compared with Nystatin except between (100 and Nystatin) mg/ml in which there were no significant difference. In ethanol extract only the concentrations (100 and 75) mg/ml inhibited the growth of Candida albicans and there were significant differences between all concentrations (P≤0.05) with Nystatin, while shear bond strength was increased in ethanol extract and there were significant differences with the control (P≤0.05), but it was not affected in oil extract and there were no significant differences with the control (P>0.05). Interestingly, it’s concluded that oil and ethanol extracts of Artemisia aerials parts had an effect on Candida albicans, while shear bond strength was not affected by oil extract but increased in ethanol extract.

Solar energy is one of the most promising renewable energy sources. The potential solar energy has a capacity to meet all energy requirements for human survival on planet earth. Some applications such as a thermoelectric generator, electric power generation with the assistance of solar panels and water applications are required to reduce the demand for electricity generated by conventional power plants. The current work evaluates the effectiveness of solar energy for supplying the police building located in Diyala, Iraq. The installed renewable power system consists of photovoltaic/ battery system set with grid connection installed on the roof of the building with a capacity of 5.52 kWp and battery unit (200 A, 48 Volt). Based on the daily average load kWh and daily average solar irradiance for the selected site (4.3 kWh/m2), the results of the energy generated by the system for two selected days showed that for a sunny day is about (11.63 kWh) and for party cloudy day is about (8.02 kWh). The average of energy fed to the grid for a sunny day was recorded more by more than 3.0 kWh and for party cloudy day by more than 4.0 kWh. The system installed at the first day of February of the year 2021. The obtained results encourage to install of photovoltaic systems in the selected site which can feed such facilities with renewable energy and deliver energy to the grid.

Abstract. The influence of both anthropogenic and forest-fire emissions, and their subsequent chemical and physical processing, on the accuracy of weather and
air-quality forecasts, was studied using a high-resolution, online coupled
air-quality model. Simulations were carried out for the period 4 July through
5 August 2019, at 2.5 km horizontal grid cell size, over a 2250×3425 km2 domain covering western Canada and USA, prior to the use
of the forecast system as part of the FIREX-AQ ensemble forecast. Several
large forest fires took place in the Canadian portion of the domain during the
study period. A feature of the implementation was the incorporation of a new
online version of the Canadian Forest Fire Emissions Prediction System
(CFFEPSv4.0). This inclusion of thermodynamic forest-fire plume-rise
calculations directly into the online air-quality model allowed us to
simulate the interactions between forest-fire plume development and weather. Incorporating feedbacks resulted in weather forecast performance that exceeded
or matched the no-feedback forecast, at greater than 90 %
confidence, at most times and heights in the atmosphere. The feedback forecast
outperformed the feedback forecast at 35 out of 48 statistical evaluation
scores, for PM2.5, NO2, and O3. Relative to the
climatological cloud condensation nuclei (CCN) and aerosol optical properties used
in the no-feedback simulations, the online coupled model's aerosol indirect
and direct effects were shown to result in feedback loops characterized by
decreased surface temperatures in regions affected by forest-fire plumes,
decreases in stability within the smoke plume, increases in stability further
aloft, and increased lower troposphere cloud droplet and raindrop number
densities. The aerosol direct and indirect effect reduced oceanic cloud
droplet number densities and increased oceanic raindrop number densities,
relative to the no-feedback climatological simulation. The aerosol direct and
indirect effects were responsible for changes to the near-surface
PM2.5 and NO2 concentrations at greater than the
90 % confidence level near the forest fires, with O3
changes remaining below the 90 % confidence level. The simulations show that incorporating aerosol direct and indirect effect
feedbacks can significantly improve the accuracy of weather and air-quality
forecasts and that forest-fire plume-rise calculations within an online
coupled model change the predicted fire plume dispersion and emissions, the
latter through changing the meteorology driving fire intensity and fuel
consumption.
Spectrometric measurements of atmospheric propane (C3H8)

Published: July 2021

Abstract. We report measurements of atmospheric C3H8 from analysis
of ground-based solar absorption spectra from the Jet Propulsion Laboratory (JPL) MkIV interferometer.
Using the strong Q-branch absorption feature at 2967 cm−1, we can
measure C3H8 in locations where its abundance is enhanced by
proximity to sources (e.g., large natural gas fields, megacities). A case
study of MkIV C3H8 measurements from Fort Sumner, New Mexico, shows
that amounts are strongly correlated with ethane (C2H6) and with
back-trajectories from SE New Mexico and western Texas, where the Permian Basin
oil and natural gas field is located. Measurements from JPL, California,
also show large C3H8 enhancements on certain days but more
correlated with CO than C2H6. From high-altitude balloon-borne
MkIV solar occultation measurements, C3H8 was not detected at any
altitude (5–40 km) in any of the 25 flights.
Wildfire history of the boreal forest of south-western Yakutia (Siberia) over the last two millennia documented by a lake-sediment charcoal record

Published: July 2021

Abstract. Wildfires, as a key disturbance in forest ecosystems, are
shaping the world's boreal landscapes. Changes in fire regimes are closely
linked to a wide array of environmental factors, such as vegetation
composition, climate change, and human activity. Arctic and boreal regions
and, in particular, Siberian boreal forests are experiencing rising air and
ground temperatures with the subsequent degradation of permafrost soils
leading to shifts in tree cover and species composition. Compared to the
boreal zones of North America or Europe, little is known about how such
environmental changes might influence long-term fire regimes in Russia. The
larch-dominated eastern Siberian deciduous boreal forests differ markedly
from the composition of other boreal forests, yet data about past fire
regimes remain sparse. Here, we present a high-resolution macroscopic
charcoal record from lacustrine sediments of Lake Khamra (south-west Yakutia,
Siberia) spanning the last ca. 2200 years, including information about
charcoal particle sizes and morphotypes. Our results reveal a phase of
increased charcoal accumulation between 600 and 900 CE, indicative of
relatively high amounts of burnt biomass and high fire frequencies. This is
followed by an almost 900-year-long period of low charcoal accumulation
without significant peaks likely corresponding to cooler climate
conditions. After 1750 CE fire frequencies and the relative amount of
biomass burnt start to increase again, coinciding with a warming climate and
increased anthropogenic land development after Russian colonization. In the
20th century, total charcoal accumulation decreases again to very low
levels despite higher fire frequency, potentially reflecting a change in
fire management strategies and/or a shift of the fire regime towards more
frequent but smaller fires. A similar pattern for different charcoal
morphotypes and comparison to a pollen and non-pollen palynomorph (NPP) record
from the same sediment core indicate that broad-scale changes in vegetation
composition were probably not a major driver of recorded fire regime
changes. Instead, the fire regime of the last two millennia at Lake Khamra
seems to be controlled mainly by a combination of short-term climate
variability and anthropogenic fire ignition and suppression.
