Authors: Alinda Sylva Dinie , Margono Anggraini , Putranto Aditya Wisnu , Maharti Ike Dwi , Amalina Retno , Rahmi Sherly Firsta
Published: July 2021

Aims:

The aim of this study was to compare compressive strength and its correlation with the surface morphology and chemical elements of GIC and Giomer, as well as to determine the fluoride amount effect on the bacterial biofilm formation of GIC and Giomer.

Background:

The liability of Glass Ionomer Cement (GIC) mechanical properties is overcome with better antibacterial properties among restorative materials. Another fluoride-releasing restorative material, such as Giomer, has been discovered and is expected to overcome the issues with GIC’s mechanical properties; however, no research has been conducted related to antibacterial properties in Giomer.

Objective:

To compare compressive strength and its correlation with the surface morphology and chemical elements, then determine the fluoride amount effect on the bacterial biofilm formation of GIC and Giomer.

Methods:

Sixteen specimens of GIC and Giomer were prepared for a compressive strength measurement with the Universal Testing Machine. Sixteen specimens of GIC and Giomer were incubated for three days with the Streptococcus mutans culture at 37°C. The bacterial colonization was calculated using the Colony Forming Unit (CFU) and bacterial adhesion was calculated using a Scanning Electron Microscope (SEM). The mechanical properties’ compressive strength measurement, surface morphology, and chemical elements analyses were performed using SEM-EDX.

Results:

The compressive strength of Giomer was higher than GIC (P=0.001). The higher compressive strength of Giomer was reflected by a predominant regular surface, fewer voids, smaller and denser particles, and a higher content of silica and carbon. The bacterial biofilm on the surface of Giomer was higher than GIC, although there was no significant difference. GIC and Giomer have identical chemical elements: C, O, F, Na, Al, Si, P, and Ca.

Conclusion:

The compressive strength of Giomer is better than GIC; however, the biofilm formation of Giomer is higher than GIC, whereas GIC has a higher fluoride content but inferior in surfaces morphology characteristic

Authors: Kumar Mohit , Mandal Uttam Kumar
Published: July 2021

The objective of the present article is to review various aspects of dissolution studies of
dosage forms performed with the flow-through apparatus (USP type-IV apparatus). USP type-IV
apparatus is comprised of a pump that compels the dissolution media upwards via the flow-through
cell. A reservoir of dissolution medium is attached to the cell that is mounted vertically with a filter
system to restrain the escape of un-dissolved particles. The apparatus is specially designed for powders,
microparticles, pellets and tablets. In this type of in vitro dissolution method, the test sample
is placed in the bottom of the small-volume flow-through cell; the solvent passes through it at a
temperature of 37°C. This study is very important to build up the in-vivo and in-vitro relationship.
Likewise, this study is used to distinguish the extent of medication released from the tested sample
so as to foresee its in vivo viability in actual patient population. The flow-through cell is used to determine
the dissolution of micro-particulate, suppositories, implants, controlled-release formulations
with drugs that have very low aqueous solubility. The drugs with small particle size and large
surface area are dissolved at a faster rate as compared to other existing and compendial dissolution
apparatuses. The article also highlights some of the in vitro dissolution studies carried out with the
USP type-IV apparatus.

Authors: Arkani Toktam , Firoznia Ali , Izanloo Cobra
Published: July 2021

Background:

Considering the high cost of nano-particles chemical synthesis and bacteria’s
high resistance against antibiotics, investigating silver particles biosynthesis and their effect
on clinical and standard strains of different bacteria is very important.

Objective:

This study investigates the feasibility of green synthesis of silver chloride nanoparticles
by labiosa (Bunge) Adylov, Kamelin & Makhm Phlomoides (Eremostachys labiosa
Bunge) herbal extract and Phlomoides binaludensis Salmaki & Joharchi (Binaloud Cistanche tubulosa)
plant.

Methods:

Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), UV-Visible Spectroscopy,
and Energy-Dispersive X-ray Spectroscopy (EDS) are used for nano-particles characterization.
The antibacterial property of extracts and synthesized nano-particles was evaluated
against Staphylococcus aureus, Bacillus cereus and Escherichia coli by agar disk diffusion and
well diffusion, respectively. As antioxidants existing in plants are expected to act as regenerators
in nano-particles synthesis, the plants used were investigated considering the existence of antioxidants
through two DPPH and FRAP methods. Total values of phenol and IC50 were determined
by the extract of considered plants.

Results:

The results showed that what has been successful in nano-particles synthesis is silver
chloride nano-particles synthesis, which is due to the existence of chlorinated compounds in the
herbal extract. Synthesized nano-particles are spherical, and their size is in the range of 27-35 nm,
and synthesized nano-particles were distributed consistently. Also nano-particles enjoy significant
antibacterial activity.

Conclusion:

IC50 was 0.56 mg/ml and 0.96 mg/ml for the aerial organs of Eremostachys labiosa
Bunge and Binaloud Cistanche tubulosa, respectively, in this study, while it was 0.38 mg/ml for
BHT synthetic antioxidant. Also, iron regeneration ability reported 255.990 and 64.110 Fe ion

cerco à autonomia das escolas
Authors: Meira Manuel Vale Fernandes
Published: July 2021

O artigo analisa o impacto das plataformas eletrónicas da administração educativa no tópico descentralização/centralização e reforço/limitação da autonomia das escolas e dos atores escolares. Os resultados apresentados baseiam-se num estudo de caso centrado numa organização escolar e mostram-nos que as medidas de reforço da autonomia das escolas e da descentralização têm sido esvaziadas na prática pela ação das plataformas eletrónicas. A rigidez dos algoritmos das plataformas eletrónicas facilita o cumprimento das diretivas da administração central e a sua aceitação na medida em que são percebidas como meras operações técnicas destinadas a conseguir a maneira mais correta de funcionar com o mecanismo eletrónico. Por outro lado, a intensificação da especialização tecnológica e a sua concentração no centro aumenta o sentimento de descapacitação das organizações escolares que, muitas vezes, preferem a centralização como forma de resposta à atribuição de competências sem as correspondentes condições para o seu exercício. Esta circunstância vem evidenciar ainda mais o facto de que nem o poder central está disposto a abdicar do controlo burocrático centralizado nem as organizações escolares estão preparadas para assumir o princípio democrático da autonomia das escolas.

Published: July 2021

No presente artigo, apresentamos uma reflexão acerca da arte como campo de saber legitimado (ou não) para a formação de professores(as) pedagogos(as) e a repercussão dessa formação em suas futuras atividades docentes com artes, nas séries iniciais da Educação Básica, e a relação dessa formação com o que determinam os documentos legais no país. Para isso, analisamos o contexto da formação inicial em Pedagogia, pontuando brevemente a evolução do campo da Arte no currículo escolar no Brasil, com foco na educação estética. Discutimos também sobre os saberes em artes que são (ou deveriam ser) proclamados e exercidos nos currículos e o que, de fato, se pratica nos currículos dos cursos de Pedagogia da Universidade Estadual do Ceará – UECE/Faculdade de Educação de Itapipoca – FACEDI – e a articulação desses currículos com as atividades de pesquisa e extensão existentes nessa instituição. Os resultados de nossas análises apontam para a compreensão de que currículo não é mera prescrição, mas um conjunto de possibilidades que nos exige considerar a diversidade presente no cotidiano escolar como elemento formativo e interventivo.

Initial Management of COVID-19 Outbreak in Mexico
Authors: Caamal-Olvera Cinthya G. , Arteaga García Julio César
Published: July 2021

This paper analyzes the initial stage of the pandemic COVID-19 in Mexico. The objective is to test whether the contagion risk perception and the authorities' initial prevention messages influenced the COVID-19 deaths. We estimate longitudinal elasticities of deaths to confirmed COVID-19 cases by accounting for measurement error and endogeneity issues. We find that confirmed cases and poverty levels are endogenous. The limitation arises because of the underreported COVID-19 deaths. Our contribution is to identify an association with the individual and political risk perception to the number of COVID-19 deaths. The results show that municipalities with more confirmed cases aware of being in contact with another person affected by COVID-19 have fewer deaths. However, emergency management, federal and state, had weak effects of reducing the lethality rate. We infer that better individual risk awareness is an essential factor in reducing the number of deaths from COVID-19.

A Case for Pedagogic Writing Instruction for Pre-Service Teachers to Learn Applied Grammar in the Context of Their Own Writing
Authors: Wyandotte Annette M.
Published: July 2021

Revived interest in grammar as a tool to teach writing is a phenomenon of the 21st century since inquiry in the 50s determined it to have “no positive impact on” writing instruction (Locke, 2005; Qtd. in McCormack-Colbert, Ware, & Jones, 2018, p. 165). Yet in the past two and a half decades, the concepts of Contextualized Grammar and Pedagogic Grammar have earned recognition in English and Language Education as a new kind of instruction shown to enhance writing when providing learners strategic mini lessons in grammar. This article also proposes the converse: in a college grammar course, strategic writing instruction assists students to learn grammar and usage in an applied setting of creating, revising, and editing their own texts. This article first reviews the premises and bases for the reappearance of grammar to teach writing and then describes the writer’s parallel approach to grammar instruction through the strategic use of writing assignments referred to here as Pedagogic Writing. The article closes with an account of the performances and perceptions of pre-service teachers sent to English by the School of Education to take ENG G 207, Grammar and Usage, showing preliminarily their successful application across three semesters, from spring 2020 through spring 2021.

Published: July 2021

Covid Pneumonia is a life-threatening bacterial disease in humans that affects one or both lungs and is caused by the bacteria Streptococcus pneumonia. Also known as Covid-19, this is a respiratory illness that was first discovered in Wuhan, China. Expert radiotherapists must evaluate chest X-rays used to diagnose pneumonia. As a result, establishing an autonomous system for detecting pneumonia would be advantageous for treating the condition quickly, especially in distant places. The statistical results show that using pre trained CNN models and supervised classifier algorithms to analyse chest X-ray pictures, specifically to diagnose Pneumonia, can be highly advantageous. By constructing certain convolution neural network designs, we are developing a classifier model that accurately predicts if a person has covid or pneumonia.

Published: July 2021

Detection of nutritional deficiencies in plants is vital for improving crop productivity. Timely identification of nutrient deficiency through visual symptoms in the plants can help farmers take quick corrective action by appropriate nutrient management strategies. Manual checking of plant nutrient deficiency does not give adequate result as naked eye observation is old method and requires more time for deficiency recognition, and also need expert person. which is very costly for farmers hence it is non-effective. To overcome disadvantages of traditional eye observing technique, we used the application of computer vision and machine learning techniques offers new prospects in nondestructive field-based analysis for nutrient deficiency detection. In the proposed system, we are using unsupervised machine learning algorithm, which learns features on its own from given dataset. Initially, we perform preprocessing on image to be tested. preprocessing includes image enhancement, image restoration, image segmentation. classifier predicts the result based on the image we passed. The system will provide the definite result about a nutrient deficiency along with disease if any and also provide solution for nutrient deficiency.

A High Power Density Converter with a Continuous Input Current Waveform for Satellite Power Applications
Authors: Vivek Kema
Published: July 2021

Conventional Active Clamp-Forward topology is studied for a satellite converter owing to its comparitively simple structure, minimum number of components and fine clamping capability concerning its switch voltage stress. However, it has a high switch voltage stress,a high di/dt level and has pulsating input current shape. These are disadvantageous with respect to the EMI filter size and high input voltage converter applications.To get the better of these drawbacks, a new ACF topology with a continuous input current waveform is proposed . By this proposed waveform ,the voltage stresses on the main switches are relieved. This is crucial reliability of satelite FET switches, by utilizing a two series connected structure. These conditions will allow the proposed converter to serve as a high input voltage, high power density satellite converter.

Authors: . Neeraj
Published: July 2021

Parkinson's disease (PD) is one of the major progressive neurological disorders. It occurs due to a low level of a chemical substance in the brain known as Dopamine, which controls the muscle movements of the body. In many cases, PD occurs due to a low level of dopamine. PD generally appears in persons between the ages of 50 & 60. Some common symptoms of Parkinson's are slow movements, tremors, change in voice, depression, anxiety, hallucinations, psychosis, etc. Diagnosis of PD is done by CAT (Computerized Axial Tomography) scan or MRI (Magnetic Resonance Imaging, and DAT (Dopamine Transporter) scan. No specific cure for PD but Medication, Surgery, Adequate rest, exercise, and a balanced diet, and Several different drugs may help to relieve Parkinson's Disease (PD). According to the in silico study, we found that Rosmarinic Acid (RA) was the compound, which may inhibit the activities of Sequestosome-1. After in vitro and in vivo studies, Rosmarinic Acid may be an effective drug to control Parkinson's disease (PD).
Analytical Prediction and Finite Element Simulation of Steel Tubular Pier with Stiffener
Authors: Johnson Densy
Published: July 2021

Hollow steel tubular members are extensively used in multi storey car parks, bridge piers, building columns, offshore structures and subway columns. An earthquake of moderate intensity can result in extensive damage and potential collapse of bridges. During a large earthquake, traditional seismic lateral resisting system can experience significant damage and it cause residual drifts. Thus, a suitable strengthening or retrofitting technique needs to be developed for minimising structural damage and human casualty due to imposed lateral impact loading. The steel shell acts as longitudinal and transverse reinforcement. The primary role of stiffeners is to prevent local buckling prior to overall buckling and to increase overall buckling strength. In seismic applications, an additional, yet equally important role of stiffeners is to increase ductility of the cross section under cyclic loading. Stiffeners are the secondary plate or sections which are attached to web or flanges to stiffen them against out of plane deformation. This paper presents the research work on analytical prediction and finite element simulation of steel tubular pier with stiffeners. A non-liner 3D model was developed using ANSYS programme.

Program Inovasi Desa merupakan pendampingan yang dilakukan untuk mendorong pemanfaatan produk unggulan dengan meningkatkan kualitas supaya lebih baik lagi. Program inovasi desa merupakan kegiatan yang dapat meningkatkan produk unggulan sebagai bentuk upaya pengabdian kepada masyarakat untuk meningkatkan kesejahteraan dan perekonomian masyarakat pada masa pandemi covid-19.

Pengabdian kepada masyarakat KKN PPM edisi covid-19 bertempatkan di Desa Karangrejo, Kecamatan Kromengan, Kabupaten Malang. Penduduk asli Desa Karangrejo mayoritas pedagang jamu gendong. Himbauan pemerintah melarang warganya untuk beraktivitas diluar terlebih berkumpul dengan banyak orang guna mencegah penularan virus Covid-19 berdampak pada pedagang jamu tersebut. Pedagang jamu mengalami dampak yang luar biasa mereka tidak bisa menjual jamu dengan cara berkeliling seperti biasa sementara jamu gendong tersebut hanya bertahan sepekan saja. Hal ini juga akan menjadi kendala apabila jamu tersebut dijual secara online karena batas waktu bertahannya relatif pendek. Sehingga, kami memberikan inovasi terhadap pengemasan jamu supaya dapat bertahhan lebih lama yaitu dijadikan serbuk jamu dan dikemas secara menarik.
Imaginando cómo podría ser el conocer reflexivo de los Bernabé Bernal
Authors: Mancera Ortiz Gabriel
Published: July 2021

El presente artículo se configuró a partir de la versión del proyecto de investigación “Conocer reflexivo en contextos de modelación matemática desde una perspectiva socio crítica”, centrando su atención, en tanto problema de investigación, en el cuestionamiento ¿Qué caracterizaría el conocer reflexivo de los Bernabé Bernal si en su historia escolar la modelación matemática desde la perspectiva socio crítica resultara ser un medio regular en su formación? Particularmente, se busca reportar el análisis de una experiencia de aula la cual se basa en un ambiente de modelación matemática, pensado desde la perspectiva socio crítica, en la que busca relacionar características del conocer reflexivo que desarrollan un grupo de estudiantes de grado undécimo en un colegio público de Bogotá - Colombia. Se inicia con una idea metodológica de investigación denominada investigación crítica, la cual pone en consideración que en una investigación podría tenerse en cuenta no solo lo que está ocurriendo sino también lo que podría haber ocurrido y lo que podría ser imaginado, los datos (registrados en grabaciones de audio y video, entrevistas, escritos y producciones de los estudiantes) fueron analizados, considerando la noción de los actos dialógicos. Luego se presenta al conocer reflexivo y la modelación matemática a partir de una perspectiva política de la Educación Matemática. De esta manera, se considera que el contexto en que los estudiantes desarrollan tal conocer es un elemento del punto de partida que debemos tener en cuenta en nuestras prácticas pedagógicas e investigativas. Así, se destacan varias reflexiones, entendidas como un abrebocas para iniciar la discusión en torno a cuatro rasgos distintivos del proceso desarrollado por los estudiantes: pensando en el otro, lectura crítica y matemática, prácticas con las matemáticas y la colectividad. Con este marco se caracterizan tales rasgos como características del conocer reflexivo desarrollado por los estudiantes.
Manuel Ancízar y la enseñanza de la economía política
Authors: Chaparro Germán Raúl
Published: July 2021

Este trabajo analiza la contribución de Manuel Ancízar a la enseñanza de la economía política; se toma como referencia el programa del curso impartido en la Universidad Nacional de Colombia, en 1873. Este programa permite identificar influencias teóricas y temas de interés que guardan relación con el proyecto republicano que Ancízar, como gran promotor de redes de sociabilidad, divulgador de ideas, funcionario público, político y profesor, se esforzó por promover. A través del programa, los libros de texto utilizados y las disertaciones de sus estudiantes, se intentan identificar sus influencias teóricas y los problemas a los que concedió mayor importancia.
Aplicación del modelo de ajuste parcial nerloviano para estimar la elasticidad de la oferta de plátano en Colombia
Authors: Cancino Susan , Cancino Escalante Giovanni Orlando
Published: July 2021

El objetivo del presente estudio fue estimar la respuesta de la oferta del plátano y las elasticidades de corto y largo plazo mediante el modelo de ajuste parcial desarrollado por Nerlove, tomando como base el periodo entre 2000 y 2018. Se aplicó un diseño de investigación explicativo, cuantitativo y correlacional y para la estimación empírica se empleó la metodología de los vectores autorregresivos. Los resultados indicaron que los coeficientes asociados al precio y producción rezagadas fueron positivos, significativos y coherentes con la teoría económica. Las elasticidades calculadas de corto plazo fueron inelásticas y similares a estudios relacionados con los cultivos permanentes por lo cual se puede inferir que las políticas de precios no son una herramienta eficaz para aumentar la oferta del plátano debido a la baja respuesta de la producción a movimientos en los precios.

Pharmacy Vaccinations
Authors: Oehlmann R. , Czirfusz A.
Published: July 2021

The vaccination rate is on the decline as parents avoid making frequent visits to healthcare facilities to visit doctors. The high cost of healthcare access in Germany, the United States, and other parts of the world has resulted in many people remaining under vaccinated or unvaccinated. The rate of pandemic outbreaks in Europe has highlighted the significance of improved communication and education about the safety and the efficacy of vaccinations alongside effective strategies of reducing the rate of disease transmission1 . Pandemics have unprecedented impacts on the families’ health and pressure on healthcare systems in Europe. During pandemics, there is widespread fear in families concerning how the pandemics will affect families and communities more especially to the compromised people in society, such as pregnant women and people with chronic illnesses. Although pharmaceutical practices are under intensive scrutiny, pharmacies' vaccinations comprise an important element in the healthcare system for pandemic diseases.
Social Aspects of Diagnosis and Treatment of Non-palpable Breast Lesions. Important Factor affecting Quality of Life in Cancer Patients undergoing Surgery
Authors: Bakos M. , Jankovic T. , Krcmery V. , Dubovcova M.
Published: July 2021

Introduction: The social aspect of breast cancer presents a serious problem all the time. Quality of women´s life after surgery must be compared to life before it. Breast cancer treatments today are likely to cause less physical deformity from surgery than two decades ago but are more complex and extend over a longer period of time. Non-palpable breast lesions are findings with non-biologically specified importance, which can be responsible for development of cancer. The authors present the diagnosis and the results of the treatment of patients with non-palpable breast lesions. They were hospitalized at the Department of Surgery in Nitra from Jan uary 2014 untilJuly 2017 and we used the SNOLLmethod or wire guided excision under ultrasound control or digital stereotaxic. Results: From January 2014 until July 2017 there were 122 patients diagnosed with non-palpable breast lesions at the Department of Surgery at our hospital. 76 (62.3%) of these patients were diagnosed with carcinoma. Wire Guided Localization was performed in 99 (81.1%) patients; sentinel node was found in 41 (33.6%) patients using the SNOLL method. From all the patients a reoperation was conducted in 4 cases (3.3%) for close or positive margin status and in 3 cases (2.5%) for false negative perioperative sentinel biopsy.                                                                Conclusion: The technique combining 99mTc-MAA (albuminmacro aggregate marked by 99Technecium) and nanocoloid is a reliable localization method for non-palpable lesions and sentinel nodes. SNOLL is a practical and oncological safe technique of excision of a subclinical lesion in combination with sentinel biopsy. This technique brings new visions for the future, especially for quality of life after surgery, changes in body image and sexuality.
Use of Apps in Pharmacy as a Communication tool
Authors: Hosseini M. , Luliak M.
Published: July 2021

In Germany, around 58 million people currently use a smartphone. 1 Not to use this communicative access to potential customers on the part of the health market would not only be negligent, but also unrealistic. Digitalization in the health sector has developed strongly in many areas in recent years and is described with different terms. These include 'e-health', 'digital health' or 'health 2.0'. However, all these terms mean the same thing: techniques and digital applications for preventing, improving and maintaining the health of the population. The tools of this technology are websites, portals, forums and, above all, apps. They are all intended to support people in actively shaping their health. 2
