Authors: Singh Pankaj Kumar , Sanyal Budhaditya , Bhatnagar Mohit , Joshi Mandeep , Verma Shreya
Published: May 2021

Aims and objectives: This study aims to assess the diagnostic accuracy and timeliness of ultrasonography by static method only for identication
of Endotracheal tube (ET Tube) placement in the trachea in emergency settings vs existing clinical methods. Material and Methods: This
prospective study was carried out in the emergency room from October 2018 till the end of March 2019. The ultrasonography was performed in 120
emergency patients only after the intubation had been completed ie, static phase. A linear probe was used over the neck to identify the predened
signs of ET intubation. Residents who perform ultrasound examination ll a form after assessment of each patient. Results: It was found that
Tracheal Intubation-USG Sensitivity was 99.1, Specicity was 91.7, Positive Predictive Value: 99.1, Negative Predictive Value was 91.7 and
Accuracy was 98.3%. Ultrasonography can be used as an adjunct tool to verify the ETTposition by Emergency Physicians which can be performed
easily after a brieng or short-course training.Conclusion:This study demonstrates that US imaging has a high diagnostic accuracy to immediately
conrm proper ETT placement post-intubation in an emergency setup. Therefore, it seems that ultrasonography using a static technique only is a
proper screening tool in determining endotracheal tube placement.

Published: May 2021

Introduction:Benign breast diseases (BBDs) are the group of non-cancerous condition which include a variety of diseases. The patient commonly presents with pain, lump or nipple discharge. The aim of this study is to study the patterns of BBDs and to correlate the clinical diagnosis with radiological and pathological ndings. Material And Methods: Hundred patients were included in the study who attended the OPD of General Surgery Department at Sanjay Gandhi Memorial Hospital, Rewa from June 2019 to May 2020. Detailed clinical history and physical examination was done for all patients fullling the inclusion criteria and clinical investigation like complete blood count, renal function test, liver function test, USG, FNAC was done. Result: Out of 100 patients, most of the females (32%) with benign breast diseases were in 21-25 years of age group and most common mode of presentation was only pain (41%) and 2nd most common was pain with lump (37%). Unilateral breast lesions were present in 90% patients with right side of breast were more commonly involved (55% patients). Commonly involved quadrant of breast was upper outer in 41% patients followed by lower outer quadrant in 24% patients. Fibroadenoma was most common benign breast disease present in 46% patients. Conclusion: Benign breast diseases are common in reproductive age group of female patients and broadenoma is the commonest of them all. In any patient presents with lump or other symptoms, the diagnosis can be made by triple assessment. It helps to rule out malignancy and provide patient's assurance regarding benign nature of disease
A Dynamic Flow 3-D Solar Energy Cell and Process
Authors: Bushong James
Published: May 2021

This paper proposed a 4-dimensional approach to solar photovoltaic energy, featuring a 3-D porous metal cell with a continuous flow of photovoltaic fluids (e.g. Colloidal Quantum Dots or perovskites) traversing throughout. Rationale and proposed governing equations indicate that significantly more power per unit 2-D panel area could be achieved, offering a method of de facto overcoming power limitations such as Shockley-Queisser and recombination in conventional 2-D passive solar panels. The main goal is to initiate thought and collaboration with experts in electrical engineering, physics, colloidal quantum dots, perovskites, capacitors/batteries, and any other related field that could help this approach become a commercial reality if there is a market fit. Potential applications include those where maximum solar power is desired yet space is limited- such as an on-board solar panel for electric vehicles.

A Connected Component Labelling algorithm for multi-pixel per clock cycle video stream
Authors: Kowalczyk Marcin , Kryjak Tomasz
Published: May 2021

This work describes the hardware implementation of a connected component
labelling (CCL) module in reprogammable logic. The main novelty of the
design is the ``full'', i.e. without any simplifications, support of a 4
pixel per clock format (4 ppc) and real-time processing of a 4K/UltraHD
video stream (3840 x 2160 pixels) at 60 frames per second. To achieve
this, a special labelling method was designed and a functionality that
stops the input data stream in order to process pixel groups which
require writing more than one merger into the equivalence table. The
proposed module was verified in simulation and in hardware on the Xilinx
Zynq Ultrascale+ MPSoC chip on the ZCU104 evaluation board.
A Coordinated Direct AF/DF Relay-Aided NOMA Framework for Low Outage
Authors: Jee Anand , AGRAWAL KAMAL , Prakriya Shankar
Published: May 2021

This paper investigates the performance of a framework for low-outage downlink non-orthogonal multiple access (NOMA) signalling using a coordinated direct and relay transmission (CDRT) scheme with direct links to both the near-user (NU) and the far-user (FU). Both amplify-and-forward (AF) and decode-and-forward (DF) relaying are considered. In this framework, NU and FU combine the signals from BS and R to attain good outage performance and harness a diversity of two without any need for feedback. For the NU, this serves as an incentive to participate in NOMA signalling. For both NU and FU, expressions for outage probability and throughput are derived in closed form. High-SNR approximations to the outage probability are also presented. We demonstrate that the choice of power allocation coefficient and target rate is crucial to maximize the NU performance while ensuring a desired FU performance. We demonstrate performance gain of the proposed scheme over selective decode-and-forward (SDF) CDRT-NOMA in terms of three metrics: outage probability, sum throughput and energy efficiency. Further, we demonstrate that by choosing the target rate intelligently, the proposed CDRT NOMA scheme ensures higher energy efficiency (EE) in comparison to its orthogonal multiple access counterpart. Monte Carlo simulations validate the derived expressions.

ANTECEDENTE Y CONTEXTO

Es bueno recordar el contexto de cómo surge la teorización, desarrollo y existencia jurídica-social de los derechos humanos. Cuatro hechos históricos relevantes merecen se acotados[1]:

La Revolución Francesa y su Declaración de los Derechos del Hombre y los Ciudadanos en 1789.

En 1776 la declaración de independencia de los Estados Unidos y su posterior promulgación en 1791 de la Carta de Derechos Fundamentales.

La Revolución Industrial, que inició a mitad del siglo XVIII, culminando su auge entre 1820 y 1840 y que significó un cambio importante en nuestra vida cotidiana.

La Segunda Guerra Mundial que culminó en 1945, produciéndose una declaración muy importante como lo es la Declaración Universal de los Derecho Humanos, proclamada en París en 1948 y que nació como un ideal común para todos los pueblos y naciones. La Declaración establece, por primera vez, los derechos humanos fundamentales que deben protegerse en el mundo entero y ha sido traducida a más de 500 idiomas.

This article presents an ontology meant to be used by algorithms for automated creation of scenes. At any time and in any place we encounter scenes: in plays, in paintings, in film frames, at hospitals, at police stations, at schools, at restaurants, at stores, everywhere. Depending on where it is located, a scene can contain more types of elements: backgrounds, objects, characters connected through their spatial relationships. Our intention is to offer the posibility of realizing many combinations of the chosen elements in order to obtain the wated scene. In practice is difficult to obtain such a result, that is why we intend to design an automatic system, which will automatically generate the scenes. The possible elements of scenes together with their relationships are grouped in an ontology which is presented in this article.

In the context of the coronavirus pandemic, the importance of disposable tableware and packaging for food has sharply increased. On the one hand, this contributed to an increase in demand for such products, and on the other hand, it strengthened the already intense competition in this market. As a result, manufacturers of disposable tableware faced the vital challenge of finding ways to maintain and expand their customer base. Today, a promising way to solve it is the development and implementation of various product and technological innovations. However, the implementation of such projects is a rather complex process, since it includes not only the creation or modification of production technologies and manufactured products but organizational changes related to all business processes of the enterprise. Practice shows that the human factor plays a special role in carrying out such organizational changes, while the greatest threat to the project is not mistakes in planning and implementation of changes but the resistance of employees. One of the ways to prevent or reduce it is to create a dedicated change support team that is distinguished by its initiative. However, in practice, it is rather difficult to identify such employees who not only want to participate in the implementation of changes but have sufficient knowledge, skills, experience to carry them out. To solve this problem, it was suggested employee behavior modeling, aimed at optimizing the team composition based on a study of various characteristics. The artificial bee colony algorithm modified by the introduction of fuzzy elements (to set the initial search positions) was used for its practical implementation.

Published: May 2021

The aim of this work is to increase the efficiency of the business process of checking clients of financial organizations by using solutions in the field of robotics. These technologies are considered as an alternative to the classic manual routine check of borrowers, which is carried out both at the initial request of clients to the Bank, and on a periodic basis, according to the legislation of the Russian Federation. The article contains a detailed analysis of the "robotic process automation" method for credit organizations in the framework of organizing the process of financial monitoring of borrowers. This technology allows you to automate standard employee actions performed in a standard graphical user interface (GUI). The article discusses the problems that arise when implementing RPA technologies in banks, the main reasons for their occurrence, as well as methods for solving them. The possible software implementation of the proposed methods using the Automation Anywhere software product and integration of the results into the MS Dynamics AX system are shown. The cost estimation of the effectiveness of this method is made, and positive non-economic effects are considered. In conclusion, we describe the main prospects for the development of RPA technology in the banking sector, possible integration with other software solutions used in credit institutions.

Published: May 2021

A residential electricity demand profile is one of the key roles for investigating the impacts of high penetration of low carbon technologies, such as photovoltaic systems and electric vehicles, on distribution networks.  However, it is difficult to identify the true daily electricity consumption of Thailand household, caused by the lack of routine real time demand monitoring and residential electricity meter is normally on monthly which is a low time resolution. In this paper, the CREST Demand Model is employed to simulate a high resolution domestic electricity demand in Thailand, without installing new monitoring devices and customer interruption, through a stochastic process which is a combination of patterns of active occupancy, the outdoor ambient light characteristic and daily activity profiles. Due to the model is based on time use survey data in UK, the outdoor irradiance and appliance configuration are adapted to fit for the Thailand case study. In order to verify the model, the synthetic load profiles by CREST Demand Model is compared against measured data from the actual monitoring in a real low voltage network in Thailand. The results show that it is promising to apply the high resolution demand model by CREST to simulate the domestic electricity demand profiles in Thailand.
Good impact of highlands grazing herbs on Fatty Acids Profile, Neutral and Polar lipids, and Antioxidant status of lamb meat from local breed in Algeria
Authors: Elaffifi Mohamed , Bouderoua Kaddour
Published: May 2021

Fats provided by animal tissues and products are particularly influenced by animal diet. There is currently an increasing consumer demand for infor-mation on ruminants’ production factors and composition of livestock prod-ucts. To meet these demands, some analytical measurements were carried outpreviously and in the present experiment in order to study the quality of meat lipids. For this purpose, twenty four lambs were allocated in two groups designated (H) and (C), fed grass from pasture and concentrate re-spectively during ninety days. After the slaughter process, samples were tak-en to be analyzed. The main results obtained showed that: The neutral and polar lipids (TG, PL) were higher in meat (H) than meat (C) (p<0.05) respec-tively. The Cholesterol decreased significantly (p<0.01).The meat from (H) showed +52.88% of polyunsaturated fatty acids (n-3 PUFA) (p<0.001). This difference was correlated significantly with antioxidant factors dominating in herbs such as tocopherol, flavonoids polyphenols andmeat enzymes such as catalase and superoxide dismutase obtained analytically. However, the level of malondialdehyde (MDA) was decreased from T60 to T300(p<0.05). Moreo-ver, the n-6 PUFA were less pronounced by half in (H)compared to (C) show-ing (p<0.05), as well as monounsaturated fatty acids (MUFA)and saturated fatty acids (SFA) respectively. In conclusion, the n-6/n-3 and LA/ALA ratios were decreased significantly (3.20vs14.31 and 2.79vs12.08) promoting health benefits. Finally, at fattening, this husbandry system proves to be eco-nomically sustainable, and able to guarantee specifications for resources diversification as organic food improving the competitiveness with conven-tional meat.

Published: May 2021

Recently, there is a great deal of attention for natural products due to its possible medicinal values. Its effectiveness has been proved through a sever-al studies in defeating some diseases. The present study aimed to investigate the antioxidant, antibacterial and antifungal activities of Urtica urens from Western Algeria. Leaves and roots were extracted with 80 % Ethanol and water. The 2.2-diphenyl-1-picrylhydrazyl (DPPH) and β-carotene bleaching tests were used to assess the antioxidant activity in addition to polyphenols analysis, while the agar well diffusion were used to screen the antimicrobial activity against some Gram-positive, Gram-negative bacteria and the fungi. Among the studied extracts, hydroalcoholic extracts of leaves and roots pre-sented the highest total phenolic values (26.2 and 20.9 mg GAE/g), flavo-noids with (15.7 and 12.2 mg quercetin/g) and condensed tannins with (56.4 and 30.1 mg GAE/g), compared to the water extracts. Once again, the 80 % ETOH leaves exhibited the highest antioxidant capacity with an IC50 of 2.59 mg/ml, followed by the water leaves with an IC50 of 6 mg/ml. On the other hand, the hydroalcoholic extracts exhibited the highest inhibition of β-carotene bleaching with 42.6 % to the roots and 37.9 % to the leaves. The ETOH leaves and ETOH roots of U. urens were the most effective extracts being able to repress the growth of the pathological tested strains including fungi. Therefore, it is recommended the use of U. urens that has been poorly recognized for a long time by the population of the selected region.
The Life Cycle of Magnetars: A Novel Approach to Estimate Their Ages
Authors: Mondal Tushar
Published: May 2021

Anomalous X-ray pulsars and soft gamma repeaters are slowly rotating, young, and isolated neutron stars exhibiting sporadic outbursts and high X-ray quiescent luminosities. They are believed to be powered by ultrastrong magnetic fields, B ∼ 1014−1015 G, associated with “magnetars.” In the peculiar case of SGR 0418+5729, timing parameters imply a dipolar B-field of 6.1 × 1012 G. This discovery has challenged the traditional picture of magnetars in terms of B-field strengths, evolutionary stages, and ages. Here we provide a novel approach to estimate a magnetar’s age by considering the self-consistent time evolution of a plasma-filled oblique pulsar with the state-of-the-art magnetospheric particle acceleration gaps. The rotational period of magnetars increases over time due to angular momentum extraction by gravitational-wave radiations, magnetic dipole radiations, and particle winds. These torques also change the obliquity angle between the magnetic and rotation axes. For SGR 0418+5729, we obtain a dipolar B-field of 1.0 × 1014 G, and a realistic age of ∼18 kyr, consistent within the magnetar paradigm.

Published: May 2021

The Milky Way disk consists of two prominent components—a thick, alpha-rich, low-metallicity component and a thin, metal-rich, low-alpha component. External galaxies have been shown to contain thin- and thick-disk components, but whether distinct components in the [α/Fe]–[Z/H] plane exist in other Milky Way-like galaxies is not yet known. We present Very Large Telescope (VLT)—Multi Unit Spectroscopic Explorer (MUSE) observations of UGC 10738, a nearby, edge-on Milky Way-like galaxy. We demonstrate through stellar population synthesis model fitting that UGC 10738 contains alpha-rich and alpha-poor stellar populations with similar spatial distributions to the same components in the Milky Way. We discuss how the finding that external galaxies also contain chemically distinct disk components may act as a significant constraint on the formation of the Milky Way’s own thin and thick disk.

< 0.05) I-QOL scores were found for older adults having UI, holding urine, leaking urine while coughing/sneezing, involuntarily urinating more than once per day, or wetting themselves. Most participants did not seek help, citing embarrassment or viewing UI as normal. UI significantly reduces older adults' quality of life. Educational and consultation services, especially for older, illiterate, married women with chronic illness, would help these individuals sustain healthy lives. [

Authors: Singh Rishi P. , Yu Justin S. , B Guruprasad , Agashivala Neetu
Published: May 2021

BACKGROUND AND OBJECTIVE:

To characterize on-label anti-vascular endothelial growth factor (VEGF) treatment patterns in patients with wet age-related macular degeneration (AMD) in clinical practice in the U.S.

PATIENTS AND METHODS:

Retrospective cohort analysis using administrative claims data from the IQVIA Open Source Databases. Treatment-naïve patients in the U.S. who received one or more wet AMD-related anti-VEGF injection from July 1, 2013, to April 30, 2017, were included. The main outcome was the injection interval closest to Month 12.

RESULTS:

This study included 21,960 patients who initiated an anti-VEGF agent (ranibizumab, aflibercept, or bevacizumab): 5,489 initiated aflibercept and 4,253 initiated ranibizumab. Among ranibizumab, aflibercept, and all anti-VEGF eyes, 38.1% (n = 2,035), 33.5% (n = 3,262), and 40.0% (n = 12,505) of patient eyes had injection intervals of less than 8 weeks, respectively, at Month 12 with the mean (standard deviation) number of injections over 12 months being 8.0 (2.4), 7.6 (2.4), and 7.8 (2.5).

CONCLUSION:

A substantial proportion of patients receive injections more frequently than every 8 weeks within the first year of treatment.

Testimonios epigráficos de época de Adriano en la vega de Antequera (Málaga), provincia Baetica
Authors: González-Conde Puente María Pilar
Published: May 2021

En la vega de Antequera (Málaga), en la provincia Baetica, se concentran algunos testimonios documentales que datan de los años de gobierno de Adriano, que se conservan todavía hoy, y que demuestran una intensa actividad de la administración romana, al mismo tiempo que la fidelidad de las ciudades de la comarca hacia la figura imperial. Estos testimonios corresponden a dos momentos diferentes en el período adrianeo, que son al mismo tiempo las fechas de mayor intensidad en la relación entre el Príncipe, su administración y los habitantes de las comunidades de la zona. Estos dos momentos son los años en torno a 122 d. C. y una década más tarde, hacia el año 132 d. C.

Este trabalho objetiva discutir sobre linguagem e síndrome de Down (SD), mais especificamente os processos alternativos de significação, tomando por base os pressupostos da Neurolinguística Discursiva (ND). Foi realizado um acompanhamento longitudinal por dois anos e seis meses com um jovem com SD, JR. O acompanhamento ocorreu com sessões semanais em uma universidade no interior da Bahia. As intervenções consistiram em contagem e recontagem de histórias, jogos, desenhos assistidos em vídeo, canções, leitura e escritas realizadas por meio da intervenção do mediador. No início da coleta dos dados, o sujeito JR apresentava fala visivelmente comprometida e não possuía autonomia em seu funcionamento de linguagem. Ao longo do acompanhamento, foi oferecido a JR um atendimento linguístico direcionado, construído sobre a valorização de suas potencialidades, sem enfatizar qualquer tipo de déficit que JR viesse a apresentar em função da sua condição. Os dados gerados neste estudo demonstram que JR avançou, pois foram-lhe ofertadas oportunidades de vivenciar práticas sociais mediadas pelo outro, bem como, foram oferecidas propostas que possibilitaram a ele operar sobre a linguagem e, assim, circular efetivamente pelo uso social da fala, mas, também, na construção de sua autonomia e na formação de sua personalidade. Os dados indicam, ainda, que JR ou qualquer outro jovem que venha a receber acompanhamento, considerando a ND, poderá apropriar-se de forma efetiva dos domínios discursivos.

Published: May 2021

Deep learning (DL) has rapidly become an essential tool for image classification tasks. This technique is now being deployed to the tasks of classifying and detecting plant diseases. The encouraging results achieved with this methodology hide many problems that are rarely addressed in related experiments. This study examines the main factors influencing the efficiency of deep neural networks for plant disease detection. The challenges discussed in the study are based on the literature as well as experiments conducted using an image database, which contains approximately 1,296 leaf images of the beans crop. A pre-trained convolutional neural network, EfficientNet B0, is used for training and testing purposes. This study gives and emphasizes on factors and challenges that may potentially affect the use of DL techniques to detect and classify plant diseases. Some solutions are also suggested that may overcome these problems.
An Improved Approach for Multiple Image Encryption Using Alternate Multidimensional Chaos and Lorenz Attractor
Authors: Dua Mohit , Dua Shelza , Jaroli Priyanka , Bisht Ankita
Published: May 2021

This chapter proposes a multiple image encryption method based on multi-dimensional chaotic equations. Four-dimensional differential chaotic equations of Lorenz attractor have been used to generate the initial security key, and alternate logistic maps have been used for encryption. Initially, three input images are used in a matrix form, where size of each image is M×N, and a composite image is derived by combining the one dimensional matrix of the input images, where size of the composite image matrix is 3×(M×N). Secondly, Lorenz attractor (LA) generates the security key using the composite matrix, and then alternate logistic map is applied with one-dimensional and two-dimensional logistic maps to confuse the matrix. In every iteration of logistic maps, XOR operation is used to encrypt the composite image, and at last, transformation is applied to diffuse the matrix. Finally, the encrypted composite image is obtained in the form of a confused matrix. The proposed algorithm reduces the correlation, increases entropy, and enhances performance of encryption.

The novel coronavirus (COVID-19), which started in the Wuhan province of China, prompted a major outbreak that culminated in a worldwide pandemic. Several cases are being recorded across the globe, with deaths being close to 2.5 million. The increased number of cases and the newness of such a pandemic has resulted in the hospitals being under-equipped leading to problems in diagnosis of the disease. From previous studies, radiography has proved to be the fastest testing method. A screening test using the x-ray scan of the chest region has proved to be effective. For this method, a trained radiologist is needed to detect the disease. Automating this process using deep learning models can prove to be effective. Due to the lack of large dataset, pre-trained CNN models are used in this study. Several models have been employed like VGG-16, Resnet-50, InceptionV3, and InceptionResnetV2. Resnet-50 provided the best accuracy of 98.3%. The performance evaluation has been done using metrics like receiver operating curve and confusion matrix.
Locally-Adaptive Naïve Bayes Framework Design via Density-Based Clustering for Large Scale Datasets
Authors: Bulut Faruk
Published: May 2021

In this chapter, local conditional probabilities of a query point are used in classification rather than consulting a generalized framework containing a conditional probability. In the proposed locally adaptive naïve Bayes (LANB) learning style, a certain amount of local instances, which are close the test point, construct an adaptive probability estimation. In the empirical studies of over the 53 benchmark UCI datasets, more accurate classification performance has been obtained. A total 8.2% increase in classification accuracy has been gained with LANB when compared to the conventional naïve Bayes model. The presented LANB method has outperformed according to the statistical paired t-test comparisons: 31 wins, 14 ties, and 8 losses of all UCI sets.
The Unexpected Online Learning Pivot

Published: May 2021

The COVID-19 pandemic that swelled into an economic maelstrom during the year 2020 also focused a direct hit on higher education. As faculty and students were heading into spring break, the seismic impact of impending changes were realized. Within the digital age, the technology has raised an ever-increasing recognition of differentiated styles of teaching and learning, yet so many faculty held tightly to the traditional face-to-face instructional environments. Yet faculty persistence won the day, reflecting the ability of higher education faculty to succeed through the swerving road of the unknown, the tightrope that they walked dangling daringly over the online chasm of understanding. This chapter focuses on the initial foray into the principles of instruction, followed by an understanding of the differentiation between optics and outcomes, developing strategic priorities, an understanding of nuanced teaching and learning, and the gratitude and understanding conceived through critically reflective pedagogy and journaling.

Published: May 2021

In this chapter, eight Canadian teacher-educators describe how they collaboratively transformed a face-to-face Master of Education course focused on education for social justice into an online summer course. Each of the eight instructors wrote a short narrative of their experience, and these were woven together to show examples of how this collaborative endeavor worked. Themes emerging from their writing included support through team meetings, faculty development and mentorship through shared resources, support through individuals' diversity of experience, support through building community, transitioning from face-to-face to online learning, and the importance of support from a pedagogically-informed technological support team. Reasons why this collaboration worked are discussed in the conclusion.
