MANAGEMENT OF CERVICAL ROOT FRACTURE OF ANTERIOR TEETH WITH OPEN APEX AND CLOSED APEX BY FRAGMENT REATTACHMENT - A REPORT OF TWO CASES
Authors: Tomar Sachin , Thakur Seema , Chauhan Deepak
Published: October 2022

Background: Dental trauma is one of the main causes of loss of teeth in children. Dental trauma is a
situation in which the patient is not only affected physically, but socially or psychologically also.
Treatment of fractured teeth, particularly in young patients, is further complicated by the often difcult but essential procedure.
Advances in adhesive dentistry have enabled dentists to use the patient's own fragment to restore the fractured tooth.
Reattachment is such an ultraconservative technique that it provides safe, quick, and aesthetically please results. In Method:
the rst case, the cervical root fracture in 11 with open apex was treated by root canal treatment followed by bio-dentine apical
plug and then with the help of bre post, the tooth fractured fragment were reattached. In the second case, a cervical root
fracture in 11 with closed apex was treated by root canal treatment followed by reattachment of the fragment by bre post.
Results: The patient was reevaluated in the subsequent follow-up, the patient was asymptomatic with favourable soft tissue
healing and good aesthetics. This case report includes proper history taking, diagnosi Conclusion: s, and treatment of cervical
root fracture by fragment reattachment to educate the population that reattachment is an inexpensive treatment option for the
patient with a positive emotional and psychosocial response.

Published: October 2022

Objective: To increase vaccine awareness, we aimed to determine individuals’ knowledge and behavioral approach to the COVID-19 vaccine.

Methods: The data of this cross-sectional study were obtained online between June and July 31, 2021. One thousand one hundred seventy-six people over the age of 18 were included in the study. The researchers developed a data collection form consisting of 27 questions. Mean±standard deviation and median (1st quarter-3rd quarter) values, numbers, and percentages were used to summarize the data. Chi-square (χ2) test was used to show the relationship between categorical variables. Independent predictors of participants’ vaccine hesitancy/rejection were analyzed using logistic regression. Statistically, data with p<0.05 were considered significant.

Results: A total of 1176 people, 55.7% of whom were women, with a mean age of 39.75±11.27 years, were included in the study. 71.6% of the participants were married, and 78.9% had a university/postgraduate degree. 9.7% of the participants stated that they were hesitant about the COVID-19 vaccine, and 7.1% refused the COVID-19 vaccine or would not be vaccinated when it was their turn. According to the logistic regression model established to examine the factors that may affect vaccine rejection; Age, the resources used to obtain information about the vaccine, the thought that it would not protect for two years, or the vaccine side effects were high, and the most effective way to get rid of the pandemic was not vaccination, were determined as the factors affecting vaccine rejection.

Conclusion: As a result of the research, it was found that the participants had a positive attitude towards the COVID-19 vaccine. It was determined that 9.7% of the study group had vaccine hesitancy, and 7.1% had vaccine rejection.

Does COVID-19 Increase the Risk of Central-Line-Associated Bloodstream Infections?
Authors: Sargın-Altunok Elif , Batırel Ayse , Ersöz Zeynep , Akay-Güven Deniz , Öztürk-Aydemir Sultan
Published: October 2022

Objectives: All over the world, there has been a rapid and significant increase in the number of critically ill patients requiring mechanical ventilation, which was over the capacity of the intensive care units (ICU). This resulted in an increased risk of healthcare-associated infections. The most significant increase was in central-line-associated bloodstream infections (CLABSI). Our study aimed to determine the effect of COVID-19 infection on CLABSI rates in patients in the COVID-ICU and the factors affecting it.

Methods: Adult patients hospitalized in the ICU between January 01, 2021, and December 31, 2021, and diagnosed with CLABSI were evaluated retrospectively. Only the first infection data of patients diagnosed with more than one CLABSI during hospitalization were included in the study. The patients were divided into two groups COVID-ICU and general ICU patients and were compared in terms of infection rate, risk factors, and agent distributions.

Results: Twenty-two patients in the COVID-ICU and 32 patients in the general ICUs were diagnosed with CLABSI, and the infection rates were 2.05 and 1.03, respectively. The patients in the COVID-ICU had a shorter length of stay in the ICU and a significantly shorter time from ICU admission to CLABSI diagnosis. There was no difference in mortality between the two groups. Infections caused by Gram-negative microorganisms developed most frequently in both groups, and Acinetobacter baumannii was the most frequent among them.

Conclusion: CLABSI is seen more frequently and earlier in patients followed in the COVID-ICU. According to our study, this situation did not significantly affect mortality. To prevent CLABSI in COVID-ICUs and improve health care quality, additional management strategies must be determined, and close data monitoring is needed.

CALCULATION OF THE RESIDUAL FUNCTION IN THE BASIS SPACE TO SEARCH FOR AREAS OF UNCERTAINTY OF THE RATE CONSTANTS OF THE POLYMERIZATION PROCESS

Published: October 2022

Предлагаeтся к рассмотрению математическая модель процесса полимеризации на катализаторах Циглера-Натта, в предположении существования только трех элементарных стадий: роста полимерной цепи, передачи цепи на мономер и передачи цепи на алюминийорганическое соединение при условии отсутствия стадии инициирования активных центров. Приведены постановки прямой и обратной кинетической задач, последняя из которых заключается в поиске областей неопределенных для констант скоростей стадий роста и передач цепи. Показано, что для рассматриваемого процесса значения констант могут быть определены в базисном пространстве, построенном на векторах констант. В отличие от исходного трехмерного пространства базисное пространство позволяет рассчитывать и визуализировать сеточные поверхности по функции невязки для среднечисленной молекулярной массы. При условии расчета невязки как максимума отклонений или суммы квадратов отклонений получают разные поверхности. Показано, как наложение поверхностей друг на друга локализует области минимума, которые впоследствии можно характеризовать как решение обратных кинетических задач. При этом такой подход позволяет оценить форму и вид «овражных» минимумов и, в целом, определять оптимальные наборы констант, идентифицирующие точки минимума

The paper proposes a mathematical model of the polymerization process on Ziegler-Natt catalysts, assuming the existence of only three elementary stages: the growth of the polymer chain, the transfer of the chain to the monomer and the transfer of the chain to the organoaluminium compound, provided there is no stage of initiation of active centers. We give the statements of direct and inverse kinetic problems, the latter of which consists in finding the regions of the chain growth stages and gears that are indeterminate for the rate constants. We show that for the process under consideration, the values of the constants can be determined in the basis space constructed on the vectors of the constants. Unlike the original three-dimensional space, the basis space allows calculating and visualizing grid surfaces by the residual function for the average calculated molecular weight. If the discrepancy is calculated as the maximum of deviations or the sum of the squares of deviations, different surfaces are obtained. We show the way the superposition of surfaces on each other localizes the minimum regions, which can subsequently be characterized as the solution of inverse kinetic problems. At the same time, this approach allows us to evaluate the shape and appearance of "gully" minima and, in general, to determine the optimal set of constants identifying the minimum points

Published: October 2022

O Indicador de Salubridade Ambiental (ISA) torna-se útil à tomada de decisão municipal para mensurar a qualidade de vida urbana, segundo o Conselho Estadual de Saneamento de São Paulo (Conesan). O objetivo foi adaptar o ISA e analisar a salubridade em quatro municípios, integrantes da bacia hidrográfica dos rios Piracicaba, Capivari e Jundiaí (UGRHI 5). A partir da revisão de literatura e da dificuldade de acesso aos dados, ajustes foram realizados no modelo original para análise do ISA em Rio Claro, Cordeirópolis, Limeira e em Santa Gertrudes. O método adaptado com 18 indicadores ilustrou que três municípios estão salubres, e o outro, em média salubridade. O esgoto sanitário não tratado é um dos quesitos para elevar a salubridade e garantir a gestão pública satisfatória. Investimentos econômicos e técnicos são necessários para assegurar os serviços equânimes à população.

Nas orientações curriculares nacionais, a estatística se faz presente desde os primeiros anos de escolarização, sendo seu ensino e aprendizagem defendidos de modo a desenvolver a literacia estatística. Este estudo discute a Educação Estatística em contextos de formação inicial de professores de matemática no Distrito Federal e em Goiás, tendo como objetivo investigar a compreensão conceitual de licenciandos em matemática sobre medidas de tendência central. Para tanto, desenvolve-se um estudo qualitativo interpretativo de 151 ingressantes e 68 concluintes em resposta a questões do Exame Nacional do Ensino Médio (Enem).  Os resultados evidenciam dificuldades em maior número entre os ingressantes em relação aos conceitos de média, moda e mediana. Tais dificuldades questionam a qualidade das interações conceituais vivenciadas por eles na Educação Básica; impõem limitações na interação desses estudantes com os domínios curriculares próprios do Curso Superior, o que prejudica sua formação, e podem limitar sua futura prática docente.
Materiais Curriculares para professores que ensinam Matemática e Prática Pedagógica
Authors: Diniz Paulo , Barbosa Jonei Cerqueira
Published: October 2022

Este estudo teve como propósito identificar e compreender as mensagens da dimensão interacional da prática pedagógica representada em materiais curriculares delineados para apoiar a aprendizagem de professores que ensinam Matemática. A técnica utilizada para a coleta de dados foi a análise documental. Na base da teoria dos códigos, de Basil Bernstein, inferiu-se sobre os graus de enquadramento expressos nos materiais, no que se refere às regras de seleção de estratégias de resolução de tarefas e às regras de conduta na interação de professores e alunos em sala de aulas. A análise dos dados sugere que, enquanto nas regras de conduta dos sujeitos na prática pedagógica o enquadramento tende a se enfraquecer, nas regras de seleção de estratégias de resolução de tarefas o enquadramento tende a se fortalecer. O enfraquecimento das regras de conduta sugere que a produção de soluções das tarefas ocorreu num processo compartilhado.

Authors: Garcia-Bustos Víctor , Cabañero-Navalón Marta Dafne , Salavert Lletí Miguel
Published: October 2022

The indiscriminate and massive antibiotic use in the clinical practice and in agriculture or cattle during the past few decades has produced a serious world health problem that entails high morbidity and mortality: the antibiotic multi-drug resistance. In 2017 and 2019, the World Health Organization published a list of urgent threats and priorities in the context of drug resistance, which only included Gram-negative bacteria and specially focused on carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa, as well as carbapenem and third generation cephalosporin-resistant Enterobacteriaceae. This scenario emphasizes the need of developing and testing new antibiotics from different families, such as new beta-lactams, highlighting cefiderocol and its original mechanism of action; new beta-lactamase inhibitors, with vaborbactam or relebactam among others; new quinolones such as delafloxacin, and also omadacycline or eravacycline, as members of the tetracycline family. The present work reviews the importance and impact of Gram-negative bacterial infections and their resistance mechanisms, and analyzes the current therapeutic paradigm as well as the role of new antibiotics with a promising future in the era of multi and pan-drug resistance.

Current Conveyor Transconductance Amplifier (CCTA) based Grounded Memcapacitor Emulator
Authors: Sinha Anant , Aggarwal Bhawna , Rai Shireesh Kumar , Gautam Shweta
Published: October 2022

A new emulator circuit for designing memcapacitor is proposed in this work. The suggested circuit is designed using a current conveyor transconductance amplifier (CCTA), a memristor and a capacitor. Behaviour of the proposed circuit has been examined for a frequency range of 0.6Hz to 6.4Hz with the help of simulations performed in LTSPICE using TSMC 180nm process parameters. It has been observed that the area inside lobes reduces with increase in frequency. In comparison to other emulators reported in literature, the suggested circuit uses fewer passive components and does not require analog multipliers, thus making it simple to design. The correctness and efficacy of the proposed design are verified using transient analysis, non-volatility analysis, and pinched hysteresis loops.

Comparative Analysis of Particle Swarm Optimization and Artificial Neural Network Based MPPT with Variable Irradiance and Load
Authors: Srivastava Spandan , Lata Charu , Lohan Prateek , Mosobi Rinchin W.
Published: October 2022

The escalating demands and increasing awareness for the environment, resulted in deployment of Photovoltaic (PV) system as a viable option. PV system are widely installed for numerous applications. However, the challenges in tracking the maximum power with intermittent atmospheric condition and varying load is significant. Maximum Power Point Tracking (MPPT) algorithms are employed and based on their convergence speed, control of external variations and oscillation, the output power efficiency, and other significant factors viz. the algorithm complexity and implementation cost, novel MPPT approach are preferable than the conventional approach. This paper presents an artificial intelligence-based optimization controller for MPPT in a PV system under varying load and irradiance conditions. Comparative analysis of Artificial Neural Network (ANN) and Particle Swarm Optimization (PSO) based MPPT is simulated and analysed. The PV system consisting of PV array and boost converter with MPPT controller feeds the DC load. The power conversion and panel efficiency are the significant factors to determine the effectiveness of tracking maximum power point. The simulation results show the performance of these controllers on the PV panel output power and the load side output power under changing loads and irradiance. In addition, the comparison of PV panel efficiency of ANN and PSO based MPPT techniques w.r.t changing loads is carried out. Based on the above analysis, PSO based MPPT algorithm marginally outperforms the ANN based MPPT algorithm. Further, the implementation of hybrid MPPT (ANN &PSO) for higher accuracy and tracking capability can be carried out as future work.

Published: October 2022

A new meminductor emulator using a capacitor, a memristor and a voltage differencing buffered amplifier (VDBA) is proposed in this paper. This reported realization of meminductor is very simple than proposed in literature as it needs only 1 active block. The proposed emulator has been found suitable for low frequency operations with electrical tunability, and multiplier free topology. The characteristics of the proposed emulator have been verified for a frequency range of 1.8Hz to 4.9Hz using the LTspice simulation tool with 180nm CMOS technology parameters. Pinched hysteresis loops observed in flux versus current plane verifies its meminductive behavior. Moreover, the non-volatility test of the proposed emulator proves its memory behavior. The pinched hysteresis loops obtained through simulations show that the lobe area reduces with increase in frequency.
Analysis of Flying Capacitor Boost Converter

Published: October 2022

This paper analyzes the working principle of flying capacitor boost converter and its different variants such as synchronous flying capacitor boost converter and n-level flying capacitor boost converter. The circuit diagram and analysis of different waveforms have been provided. Voltage conversion ratio of different converters have been provided. The lower voltage conversion ratio (VCR), higher voltage stress, and low efficiency of the boost converter at higher duty cycle levels are the primary limitations of the device. Magnetic coupling components are employed to boost the VCR, but the rating is reduced as a result. The leakage current stored in the magnetic component causes unwanted voltage spikes to occur in the switches as a result of the leakage current. For the purpose of addressing these difficulties, several active and passive clamping switches are employed. Three-level boost converters are an excellent alternative to conventional boost converters, but they have a number of disadvantages that must be considered before using them.

Authors: Kumar Abhimanyu , Jain Dr. Sanjay
Published: October 2022

In a world where climate changes and power management are becoming increasingly important, research work focuses on renewable energy based smart grid to meet adequate demands of energy. The smart grid is a modernized autonomous power network that can transmit electricity effectively, conserve resources and costs, and increase the local grid's stability. As a result, a smart grid connected multilevel inverter is presented in this work. The inverter is controlled using a model predictive control algorithm with increased levels with the primary goal of controlling the injected power generated by the renewable source, improving the quality of the current waveform, lowering THD, and eliminating the shift phase among the injected current and the grid voltage in effort to match the smart grid network's requirements. Therefore, this paper aims to show the performance analysis of multilevel inverters with predictive control for renewable energy smart grids application. The major concern was observed with most of the multi-level inverters are that with increased level total harmonic distortion (THD) is increased if switching control is not designed properly. Therefore, in this case predictive control is implemented on renewable energy based smart grid inverters to increase level with minimum voltage THD and current THD. The case analyzed voltage and current THD in the different levels of multilevel inverter. The result analysis was performed on 7, 11, 17, 21, 27, 31, 37 and 41 respectively. From result analysis it was observed that minimum THD was observed with level 31, i.e., 0.35% and at level 41 it was increased up to 0.55% which is still not high as compared to other existing MLI architectures. The result findings of proposed approach decreased THD with varying levels and outperforms better as compared to other works.
Low-Power VLSI Implementation of Novel Hybrid Adaptive Variable-Rate and Recursive Systematic Convolutional Encoder for Resource Constrained Wireless Communication Systems
Authors: Ramanna Dasari , Ganesan V.
Published: October 2022

In the modern wireless communication system, digital technology has tremendous growth, and all the communication channels are slowly moving towards digital form. Wireless communication has to provide the reliable and efficient transfer of information between transmitter and receiver over a wireless channel. The channel coding technique is the best practical approach to delivering reliable communication for the end-users. Many conventional encoder and decoder units are used as error detection and correction codes in the digital communication system to overcome the multiple transient errors. The proposed convolutional encoder consists of both Recursive Systematic Convolutional (RSC) Encoder and Adaptive Variable-Rate Convolutional (AVRC) encoder. Adaptive Variable-Rate Convolutional encoder improves the bit error rate performance and is more suitable for a power-constrained wireless system to transfer the data. Recursive Systematic Convolutional encoder also reduces the bit error rate and improves the throughput by employing the trellis termination strategy. Here, AVRC encoder ultimately acquires the channel state information and feeds the data into a fixed rate convolutional encoder and rate adaptor followed by a buffer device. A hybrid encoder combines the AVRC encoder and RSC encoder output serially and parallel, producing the solid encoded data for the modulator in the communication system. A modified turbo code is also obtained by placing interleaver between the two encoder units and building the stronger code word for the system. Finally, the conventional encoder system is compared and analyzed with the proposed method regarding the number of LUT’s, gates, clock cycle, slices, area, power, bit error rate, and throughput.
Fusion Based MR Images Denoising Technique Using Frequency Domain and Non-Local Means Filters

Published: October 2022

The non-invasive and non-ionizing properties of Magnetic Resonance Imaging (MRI) in addition to the associated good image quality as well as high resolution make MRI more attractive than many other medical imaging techniques. However, during the acquisition, transmission, compression and storage processes, the Magnetic Resonance (MR) images are corrupted by various types of noise and artifacts that degrade their visual quality. Most of the existing MR images denoising techniques give good quality images only when the noise density is low with their performances deteriorating as the noise power increases. The few methods that yield high quality images for all noise densities involve multiple complex and time-consuming processes. This paper proposes a computationally simple MR images denoising technique that consistently gives good denoising results for low as well as high noise densities. The proposed procedure fuses an MR image that is denoised by a Modified Discrete Fast Fourier Transform (MDFFT) filter with one that is denoised using a non-local means filter in frequency domain to yield a high quality output image. The main contribution of this proposed method is the employment of a novel image fusion approach that greatly improves the quality of the denoised image. The performance of the proposed technique is compared with those of the Wiener, median, adaptive median and the MDFFT filters. Objective metrics such as the Peak Signal-to-Noise Ratio (PSNR) and the Structural Similarity (SSIM) index were used in the performance assessments. The outcomes of these assessments showed that the proposed algorithm yielded images of higher quality in terms of the PSNR measure than the existing denoising techniques by at least 7.11 dB for a noise density of up to 0.5.

Published: October 2022

The multi-pixel photon counter (MPPC) has recently emerged as a great type of silicon photomultiplier to replace or compensate for conventional vacuum-based photomultiplier tubes. An MPPC provides many advantageous features, such as high electrical gain, outstanding photon detection efficiency, fast timing response, immunity to magnetic fields, low-voltage operation, compactness, portability, and cost-effectiveness. This article examines the electrical and optical characteristics of an MPPC under loosely controlled environmental conditions. We also report a measurement of the light yield captured by the MPPC when a cosmic ray passes through the plastic scintillator, demonstrating that such a setup is suitable as a simple, cost-effective tabletop cosmic ray detector for educational and research purposes.

Published: October 2022

The Carney complex (CNC) is an autosomal dominant disorder characterized by endocrine and nonendocrine tumors. Loss-of-function variants of protein kinase A regulatory subunit 1 alpha (PRKAR1A) are common causes of CNC. Here, we present the case of a patient with CNC with a novel PRKAR1A missense variant. A 21-year-old woman was diagnosed with CNC secondary to acromegaly and adrenal Cushing syndrome. Genetic analysis revealed a novel missense heterozygous variant of PRKAR1A (c.176A>T). Her relatives, suspected of having CNC, also carried the same variant. RNA analysis revealed that this variant led to nonsense-mediated mRNA decay. In vitro functional analysis of the variant confirmed its role in increasing protein kinase A activity and cyclic adenosine monophosphate levels. This study broadens our understanding of the genetic spectrum of CNC. We suggest that PRKAR1A genetic testing and counseling be recommended for patients with CNC and their families.
