Authors: B Rahul , Sangeeta Devi Mutum , J Manju , B Niveditha
Published: August 2021

Dental radiographs have long been the standard method for detecting oral illness. The harmful effects of radiation produced by dental radiographs is very low but still continuous exposure to radiation will cause harm to human health. This study aim is to estimate the awareness of radiation safety and protection in dental practice. Material and method - A questionnaire with ten questions was prepared and circulated to 100 dentists from different parts of India. Responses were gathered, and an appraisal was made as a result. Result- A total of 100 dentists responded enthusiastically and took part in it. Most of the dentists were aware of harmful effects of dental x-ray and its radiation physics and biology. Many of them are not using personal monitoring device for measuring radiation exposure. Conclusion: Radiation security expertise and experience was insufcient. While many participants had strong knowledge of radiation safety, risks, and defense, some fall into the average knowledge group, according to this study. In spite of having knowledge of harmful effects of radiation, many dentists have not used any safety protection and have not followed safety protocols. To avoid the risks in future more awareness programs have to be conducted about radiation safety and protection
A PROSPECTIVE RANDOMISED STUDY TO ASSESS WHETHER PROPHYLACTIC ATROPINE ADMINISTRATION ATTENUATES THE NEGATIVE HAEMODYNAMIC EFFECTS OF INDUCTION OF ANAESTHESIA WITH PROPOFOL AND FENTANYL
Authors: Kumar S.Dinesh , Kanthammal S.
Published: August 2021

INTRODUCTION: To provide optimal surgical conditions safely and to avoid particular complications, balanced general anaesthesia by administering a combination of propofol and fentanyl as analgesics. This type of balanced anaesthesia often induces unwanted bradycardia and hypotension, raising concerns regarding haemodynamic stability and tissue oxygenation. It is possible that atropine could replace the common clinical practice of administering vasoactive medication such as phenylephrine or norepinephrine to maintain mean arterial pressure (MAP) levels. AIM OF THE STUDY: To study the effect of atropine in suppressing the negative haemodynamic effects of induction agents- propofol and fentanyl in patients receiving general anaesthesia. MATERIALS AND METHODS: This is a prospective randomised interventional study carried out in Department of Anaesthesiology in Kanyakumari Government Medical College from January 2018 to June 2019. Patients were allocated into two groups (25 patients each) by randomization. After preoxygenation Group A: Patient receives Atropine. Patient in Group S: Receives Saline. BMI, Height, weight, Heart rate, Noninvasive blood pressure, Mean arterial pressure were recorded for every minute for 15 minutes. RESULTS: The demographic parameters like age, height, weight and BMI were similar in both groups. Comparing the SBP of both group, at base and 1 minute the difference of SBP was small. After that, the SBP was increasing trend in Atropine subjects and SBP was decreasing trend in saline subjects (P<0.001). Comparing the DBP between the two groups, Base and 1 minutes, the DBP of both groups were not differed signicantly (P>0.05),after that the DBP of Atropine group DBP was increasing trend and the DBP of saline group was decreasing trend (P<0.001). The HR of the both groups were increasing and decreasing accordingly (P<0.001). Comparing the MAP of both groups at base through 15 minutes,MAP of both group at 1minute was not differed signicantly (P>0.05),after that the MAP of Atropine subjects were increasing and Saline subjects were decreasing trend P<0.001). Percentage of fall of parameters (SBP, DBP, HR, and MAP) was more signicant at 5 and 15 mins compared to 10 mins in both th group. This may be due to the intubation response after the 5 minute of induction. All values were signicant with P<0.001. CONCLUSION: Administration of atropine before Propofol and Fentanyl induction during general anaesthesia can signicantly attenuate the fall in Systolic Blood Pressure, Diastolic Blood Pressure, Heart Rate and Mean Arterial Pressure.

Continuum models and Morse Theory in the simulation, design and evaluation of magnetic Skyrmion devices
Authors: Kotiuga P. Robert
Published: August 2021

Nanomagnetic devices such as computer gates and memory devices based on magnetic skyrmions are close to becoming a reality. In this paper we will explore the highly nonconvex nanomagnetic energy landscape in order to draw conclusions about the complexity of magnetic phenomena. Morse theoretic arguments show that, in a bounded energy interval, the number of critical points of the energy functional grows exponentially. To show this, we introduce a hierarchy of models for the design of nanomagnetic devices to provide a solid foundation for the introduction of topological tools. To reason in terms of lattice models, one must make a distinction between two types of lattices: the quantum mechanical model of the actual physical lattice and the lattice model that can be associated with a discretization of a continuum model of the physics. By focusing on the implications of Morse theory applied to lattice systems arising from the discretization of the continuum models, and the notion of “topological frustration”, we provide a framework for understanding “complexity” in the context of nanomagnetic systems. We conclude with some suggestions for making the analysis more qualitative.

Magnetic scaffolds have been investigated as promising tools for the interstitial hyperthermia treatment of bone cancers, to control local recurrence by enhancing radio- and chemotherapy effectiveness. The potential of magnetic scaffolds motivates the development of production strategies enabling tunability of the resulting magnetic properties. Within this framework, deposition and drop-casting of magnetic nanoparticles on suitable scaffolds offer advantages such as ease of production and high loading, although these approaches are often associated with a non-uniform final spatial distribution of nanoparticles in the biomaterial. The implications and the influences of nanoparticle distribution on the final therapeutic application have not yet been investigated thoroughly. In this work, poly-caprolactone scaffolds are magnetized by loading them with synthetic magnetic nanoparticles through a drop-casting deposition and tuned to obtain different distributions of magnetic nanoparticles in the biomaterial. The physicochemical properties of the magnetic scaffolds are analyzed. The microstructure and the morphological alterations due to the reworked drop-casting process are evaluated and correlated to static magnetic measurements. THz tomography is used as an investigation technique to derive the spatial distribution of nanoparticles. Finally, in silico multiphysics experiments are used to investigate the influence on the loading patterns on the interstitial bone tumor hyperthermia treatment.
Denoising with Singular Value Decomposition for Phase Identification in Power Distribution Systems
Authors: Zaragoza Nicholas , Rao Vittal
Published: August 2021

Phase identification is the problem of determining what phase(s) that a load is connected to in a power distribution system. However, real-world sensor measurements used for phase identification have some level of noise that can hamper the ability to identify phase connections using data-driven methods. Knowing the phase connections is important to keep the distribution system balanced so that parts of the system are not overloaded, which can lead to inefficient operations, accelerated component degradation, and system destruction at worst. We present a feature engineering pipeline that combines Singular Value Decomposition (SVD) with an Interquartile Range (IQR)-based nonlinear filter to denoise matrices of voltage magnitude measurements. We empirically show that this pipeline is effective in denoising data that contains either additive Gaussian, Laplacian, Cauchy, or mixed Gaussian/Cauchy noise. This approach reduces Frobenius error and increases the average phase identification accuracy over a year of non-stationary time series data. K-medoids clustering is used on the denoised voltage magnitude measurements to perform phase identification.
Stock Price Prediction Using Machine Learning and LSTM-Based Deep Learning Models
Authors: Sen Jaydip , Mehtab Sidra , Dutta Abhishek
Published: August 2021

Prediction of stock prices has been an important area of research for a
long time. While supporters of the efficient market hypothesis believe
that it is impossible to predict stock prices accurately, there are formal propositions
demonstrating that accurate modeling and designing of appropriate variables may
lead to models using which stock prices and stock price movement patterns can be
very accurately predicted. Researchers have also worked on technical analysis
of stocks with a goal of identifying patterns in the stock price movements
using advanced data mining techniques. In this work, we propose an approach of
hybrid modeling for stock price prediction building different machine learning
and deep learning-based models. For the purpose of our study, we have used NIFTY
50 index values of the National Stock Exchange (NSE) of India, during the period
December 29, 2014 till July 31, 2020. We
have built eight regression models using the training data that consisted of
NIFTY 50 index records from December 29, 2014 till December 28, 2018. Using
these regression models, we predicted the open values of NIFTY 50 for
the period December 31, 2018 till July 31, 2020. We, then, augment the
predictive power of our forecasting framework by building four deep
learning-based regression models using long-and short-term memory (LSTM)
networks with a novel approach of walk-forward validation. Using the grid-searching
technique, the hyperparameters of the LSTM models are optimized so that it is
ensured that validation losses stabilize with the increasing number of epochs,
and the convergence of the validation accuracy is achieved. We exploit the
power of LSTM regression models in forecasting the future NIFTY 50 open
values using four different models that differ in their architecture and in the
structure of their input data. Extensive results are presented on various
metrics for all the regression models. The results clearly indicate that the
LSTM-based univariate model that uses one-week prior data as input for
predicting the next week's open value of the NIFTY 50 time series is the
most accurate model.
Joint Geometry and Color Projection-based Point Cloud Quality Metric
Authors: Javaheri Alireza , Brites Catarina , Pereira Fernando , Ascenso Joao
Published: August 2021

Point cloud coding solutions have been recently
standardized to address the needs of multiple application scenarios. The design
and assessment of point cloud coding methods require reliable objective quality
metrics to evaluate the level of degradation introduced by compression or any other
type of processing. Several point cloud objective quality metrics has been
recently proposed to reliable estimate human perceived quality, including the
so-called projection-based metrics. In this context, this paper proposes a joint
geometry and color projection-based point cloud objective quality metric which solves
the critical weakness of this type of quality metrics, i.e., the misalignment
between the reference and degraded projected images. Moreover, the proposed point
cloud quality metric exploits the best performing 2D quality metrics in the
literature to assess the quality of the projected images. The experimental
results show that the proposed projection-based quality metric offers the best subjective-objective
correlation performance in comparison with other metrics in the literature. The
Pearson correlation gains regarding D1-PSNR and D2-PSNR metrics are 17% and
14.2 when data with all coding degradations is considered.

Influence of masking coatings geometric parameters on the manufacturing precision of semiconductor diodes disks-crystals
Authors: Zhukov V.V. , Stepanov S.A.
Published: August 2021

Considered is the qualification feature of dimensional abrasive jet processing when cutting masked semiconductor substrates on a silicon base into round discs-crystals. This approach is used when dividing stacked substrates into crystal disks, which have a tapered side surface and, accordingly, a difference in the size of the diameters at the ends of the crystal. The process of the formation of crystal disks is described and the dependence of the crystal taper on the masking method and the parameters of jet-abrasive processing is revealed. It is shown that crystal disks of the same size with a minimum taper can be obtained by increasing the processing time, manufacturing masking disks from wear-resistant materials, and choosing the optimal distance between the masking disks taking into account the substrate thickness.

Del soplo a la voz: la escritura como emancipación de la hegemonía en El libro vacío de Josefina Vicens
Authors: González Cruz Alexis
Published: August 2021

El presente artículo analiza la novela El libro vacío de la escritora mexicana Josefina Vicens a la luz de la propuesta teórica sobre la escritura que Hélène Cixous plantea en dos ensayos: La llegada a la escritura y La risa de la medusa. Se sostiene que su protagonista, José García, desarrolla una voz-escritura, motivada por un soplo corporal, que se resiste a una representación falologocéntrica a través de la contraposición entre la intencionalidad del narrador y la configuración textual. Se propone entonces, que, mediante la lógica femenina del gasto y el goce, la novela plantea un registro de masculinidad diferente al hegemónico y novedoso en la literatura mexicana del siglo XX.
La ciudad en la poesía de Efraín Huerta: un amor de amarga raíz
Authors: Corral Rodríguez Fortino
Published: August 2021

En el presente artículo se analiza la poesía urbana de Efraín Huerta con un enfoque semiótico. Se establece primeramente el contexto literario con que esta dialoga y enseguida se realiza el análisis intrínseco del corpus poético considerado. El contexto dialógico se describe tomando en cuenta que Efraín Huerta pertenece a la generación de 1914, que es la que prosigue inmediatamente a la del grupo Contemporáneos; en este punto se advierte que el rasgo distintivo de la generación de Huerta es su marcado interés por los asuntos sociales. El análisis de los textos tiene como objetivo explicar la manera en que se organiza y se produce la significación. Para ello se distinguen dos sistemas organizativos: uno, de tipo narrativo, basado en el esquema actancial, y otro sensorial-afectivo, que centra su atención en el devenir pasional del sujeto. El primero tiene su anclaje en la semiótica greimasiana de los años sesenta, mientras que el segundo se basa en las aportaciones de la semiótica tensiva, desarrollada en las últimas tres décadas por Jacques Fontanille y Claude Zilberberg, entre otros. Se recurre, además, a otras contribuciones teóricas como la semiótica cultural de Iuri Lotman, el modelo triádico de Peirce y algunos conceptos fundamentales del pensamiento de Gilles Deleuze.

El modelo utilizado fue RegCM, versión 4, y se comparó con los datos de precipitación y temperatura de la Base de datos CRU a nivel regional centroamericano y a nivel nacional con tres instituciones que generan datos globales (CRU, TRMM y GPCP) y los datos locales. Los esquemas convectivos utilizados fueron el esquema de Grell sobre tierra y Emanuel sobre el océano, con 50 km de resolución espacial. Los ajustes realizados a las parametrizaciones generaron buen desempeño a nivel regional Centroamericano y a nivel Guatemala a pesar de perder habilidad en algunas regiones y meses. El modelo reproduce adecuadamente el comportamiento de la precipitación estacional en la mayor parte de la temporada lluviosa. Subestima la temperatura a nivel regional, pero a nivel Guatemala muestra buen ajuste. La comparación con los datos locales observados muestra que el modelo se ajusta para el periodo en estudio; pero, es necesario realizar más experimentos con distintas resoluciones espaciales y temporales y evaluar la persistencia del modelo.

Este artículo explora el papel de las agencias de rating de sostenibilidad en el impulso del desarrollo sostenible. Más específicamente, el artículo analiza los principales retos a los que se enfrentan las agencias de rating de sostenibilidad en el actual contexto de riesgos globales y en qué medida están haciendo frente a tales riesgos. Para ello se realiza un estudio de gabinete que evidencia que el mercado de la evaluación de la sostenibilidad corporativa está experimentando importantes cambios con la inclusión en el mercado de las tradicionales agencias de rating crediticias y las nuevas regulaciones que impulsan la integración de riesgos ambientales, sociales y de gobernanza en los sistemas de medición de la sostenibilidad corporativa. Sin embargo, aún existe un amplio margen para que su papel sea mucho más transformador. Por ello, es necesario definir metodologías más concretas que permitan la medición de los riesgos de sostenibilidad a lo largo de las cadenas de suministro, dado el carácter global de estas, así como valorar el impacto tanto positivo como negativo en los Objetivos de Desarrollo Sostenible de las organizaciones que están bajo la lupa de estas agencias.

Los sistemas recomendadores son herramientas enfocadas en ayudar a los usuarios a obtener la información que mejor se corresponde con sus intereses y preferencias en un espacio de búsqueda sobrecargado de posibles opciones. A su vez, los sistemas recomendadores grupales se centran en la sugerencia de determinados tipos de ítems que tienden a ser consumidos en grupos. El presente trabajo se centra en realizar un análisis de la utilización de los sistemas recomendadores grupales como herramienta innovadora en el área del turismo, la cual constituye una de las áreas de aplicación más importantes de los sistemas recomendadores. Específicamente, se lleva a cabo un estudio de los trabaos más recientes en esta línea de investigación, realizándose una comparación atendiendo a tipo de estudio, tipo de evaluación, escenario de aplicación, fortalezas, debilidades y país en que se desarrolla el estudio. Esta comparación dio lugar a la proyección de líneas futuras entre las que se destaca el desarrollo de investigaciones de ciclo completo que incluyan nuevos algoritmos y metodologías que concluyan con un extenso estudio experimental que garantice una apropiada reutilización de los métodos propuestos.

El estado de pandemia, declarado por la Organización Mundial de la Salud, el 11 de marzo de 2020, ha puesto a prueba la capacidad de adaptación y respuesta de la sociedad. Una carrera contra el tiempo para buscar estrategias para combatir la enfermedad del nuevo coronavirus contribuye a la unión de los científicos de todo el mundo, incluyendo el uso de la nanotecnología. Por lo tanto, el objetivo del estudio fue describir el panorama de las estrategias de la nanotecnología contra COVID-19, destacando principalmente los productos y diagnósticos, vacunas y tratamientos que son o pueden ser utilizados. Se realizó una revisión bibliográfica de los estudios publicados entre febrero y noviembre de 2020 en las bases de datos PubMed, Scielo y Google Scholar. Según los índices de las distintas bases de datos, se utilizaron los términos de búsqueda “new coronavirus 2019”, “COVID-19”, “severe acute respiratory syndrome” Nanotechnology against COVID-19”, “COVID-19 Vaccines” sin ninguna restricción de idioma. El uso de materiales de base nanométrica ha indicado un gran potencial contra la diseminación del COVID-19, con la producción de productos, diagnósticos, vacunas y tratamientos. Nuestros resultados demuestran que la nanotecnología ofrece procesos, materiales y herramientas que contribuyen a aumentar la sensibilidad, agilidad y fiabilidad del diagnóstico, además de proporcionar opciones más eficaces para la prevención, el diagnóstico y las terapias.

Nanotube macroscale materials such as yarns, tapes, and sheets provide combinations of material properties that are unique relative to existing materials. Although nanotube sheet and yarn commercialization is still an emerging activity, these materials may become important in the future Business and Economics of societies. Therefore, this paper surveys current worldwide efforts toward manufacturing and commercialization of nanotube macroscale materials. The survey will help researchers, investors and economists consider how the new materials might be used in new applications and how the materials might spur economic development. Nanotube macroscale materials consist of yarn, tapes, and sheets, and exclude powdered forms of nanotubes used as filler materials. Both Carbon Nanotube (CNT) and Boron Nitride Nanotube (BNNT) materials are considered. It is anticipated that macroscale sheet and yarn with customizable properties will have broad applications. This paper is organized to provide ideas for possible areas of applications of nanotube yarn and sheet, followed by a survey of current commercialization efforts. Manufacturing barriers that must be overcome to push the development of nanotube macroscale materials toward large scale commercialization are also discussed. The paper also provides references for researchers and industry professionals who may want to further develop and put nanotube macroscale materials into their own applications.
PERDA SYARIAH DALAM TINJAUAN KONSTITUSI, FAKTA SEJARAH DAN AQIDAH ISLAM
Authors: Ali Musri Semjan Putra
Published: August 2021

There are two sides of view that need to be compromised, groups that carry radical, extremist and secular, liberal and nationalist groups. Each of them mutually clasps the one-sided truth, as if the religious and nationalist circles are two angles of a triangle that would not be possible to find. Nationalists view that the application of sharia regulations is an effort to place Muslims as an exclusive and special community in this country and place other people as second-class citizens. On the other hand radicals consider that the current system of government is in contradiction with the Islamic range absolutely, total and radical changes must be made.So this research tries to open the discourse of moderate thinking in addressing this problem, not extreme left and not right extreme. The main subject of this study will be based on three issues, sharia regulations in constitutional review, historical facts about the application of Shari'ah on Nusantra and sharia law in the review of Islamic Aqeedah. This study was conducted in the form of literary literature studies using the induction approach using qualitative analysis.The conclusion of this study, that the application of sharia regulations is part of actualizing constitutional orders into real life. Part of sharia law is valid in the unitary State of the Republic of Indonesia. Doing radical methods such as coups and for example in attempting to adopt sharia law is contrary to sharia law itself.

Everyone wants success. To achieve it, there are many supporting factors. Some can run well, but some can become obstacles. The success of the hadith scholars also do not escape from those obstacles. The economic factor is an example of their obstacles. However, they do not make it as a problem in thier study. From those different economic factors which make them success, it then creates some questions. How are their condition in their studies? Is economic condition a problem? What are the evidences, so they are said to be successful? And what are the factors that make them success? In this study, the author tries to find the authentic sources in tracing their lifes in trusted books, so the authors find that the economy is not an obstacle for them. Their success was also obtained from several factors including the recognition of the scholars, the book they wrote, the success factors in the Diwan Al Imam Al-Shafi'i, the piety and the support from their closest people.
أسباب الذلة من خلال الأحاديث النبوية
Authors: Rahmat Hidayat Syamsu Rizal
Published: August 2021

كان الناس في  الجاهلية يعبدون غير الله، ويأتون الفواحش، فكانوا على ذلك حتى بعث الله إليهم رسولًا، فآمنوا به، فغيّر الله بالإسلام أحوالَهم من الذُلِّ إلى العزّة.

والمتأمل في أحوال المسلمين في هذا الزمان ليجد بونًا شاسعًا بين أحوالهم، وبين ما يدعوهم إليه دينهم، ولهذا أصبحت أمة الإسلام غرضًا لأعدائها، بعد أن كانت أمة عزيزةً، إلا أنها لما نسيت حظًا مما ذكرت به نزلت من شامخ عزها، ولقيت ذلاً بعد عزة، ولهذا أسباب ذكرها النبي صلى الله عليه وسلم، قال تعالى:ﱡﱡﭐوَتُعِزُّ مَنْ تَشَاءُ وَتُذِلُّ مَنْ تَشَاءُ ﱠ(آل عمران: 26)  أي: تعز من تشاء بطاعتك، وتذل من تشاء بمعصيتك.

فينبغي للمسلم أن يعلم أسبابها، ويحذرها، فهذا البحث بيان أسباب الذلة للأمة،  وقسمته إلى مقدمة تشتمل على خلفية البحث، وتحديد المسألة، ومنهج البحث، ثم موضوعه ويشتمل على تعريف الذلة لغة واصطلاحًا، وأسبابها، ثم الخاتمة وفيها ذكر نتائج البحث.

ومن خلال جمع الأحاديث في الموضوع، توصلت إلى النتيجة  أن هذه الأسباب تشترك في نقطة واحدة وهي الذنوب، والعلاج هو طاعة الله.
