Proceso de agregación para estudios experimentales en ingenieria del software
Authors:   , Fernández Enrique
Published: April 2022

Antecedentes: Si bien el Meta-Análisis o agregación de estudios experimentales no es un tema nuevo en Ingeniería del Software, la práctica actual deriva sus recomendaciones exclusivamente de la medicina, ciencia que en muchos aspectos dista bastante del contexto actual de la Ingeniería del Software (IS). En general los experimentos en medicina contienen muchos sujetos. Asimismo, es frecuente la realización de replicaciones. En estas circunstancias, las técnicas de Meta-Análisis utilizadas, en especial las diferencias medias ponderadas, son fiables. Objetivo: Desarrollar un proceso de agregación propio para la Ingeniería del Software, tomando en cuenta en las características específicas de los experimentos realizados en esta área de la ciencia. Método: Para poder construir el procedimiento de agregación, se han identificado los principales problemas para realizar un trabajo de esta naturaleza en Ingeniería del Software; se ha evaluado y analizado como trabajan en otras ramas de la ciencias (como son, por ejemplo, las ciencias sociales o la ecología); se han identificado técnicas de agregación alternativas a la que habitualmente se utiliza en Ingeniería del Software; se ha evaluado el desempeño de estas técnicas en contextos como el que presenta la Ingeniería del Software mediante un procesos de simulación, estableciendo los niveles de exactitud y potencia empírica de cada una de ellas; y se han definido un conjunto de heurísticas para poder determinar con que técnica de Meta-Análisis combinar los resultados de los experimentos identificados, para generar así una conclusión en base a la mejor evidencia disponible. Resultados: Se han identificado tres técnicas de Meta-Análisis nuevas para la IS: Ratio de Respuesta Paramétrico, Ratio de Respuesta no Paramétrico y Conteo de Votos Estadístico. Se ha determinado como es el comportamiento de estas técnicas y la técnica Diferencias Medias Ponderadas, evaluando su exactitud y potencia empírica, en función del tamaño de Meta-Análisis (cantidad de experimentos y sujetos por experimentos), el tamaño de efecto y los niveles de varianza. Finalmente, se ha desarrollado un proceso de agregación de experimentos acorde al contexto experimental de la IS. Conclusiones: El proceso de agregación desarrollado permite aprovechar mejor las evidencias empíricas disponibles en el contexto de la IS, permitiendo agregar experimentos con falencias de reporte. Si bien mediante los trabajos de simulación se ha establecido como es el comportamiento de las técnicas de agregación a nivel general, no se cuenta con la suficiente precisión como para determinar con exactitud cuál es el nivel de error de las mismas para todas las posibles combinaciones de tamaños de experimentos.
Scientific inquiry, pluralism, and complementarity
Authors: grinnell frederick
Published: April 2022

Pluralism challenges science education when competing claims arise about what counts as science and how should we describe and understand natural phenomena. In 1927, the Nobel prize-winning physicist Niels Bohr introduced the idea of complementarity as a characteristic of atomic physics at the International Congress of Physics held in Como, Italy. In this essay, I will describe how Bohr’s ideas about complementarity can be useful to science educators to help explain pluralism in scientific inquiry. Bohr himself did not use the word pluralism. The extensive philosophical literature concerning science education does not mention Bohr’s ideas. However, I think that complementarity and science education can fit together.

Effects of Watershed Delineation on the Prediction of Water Quality Parameters in Gaa Akanbi Area, Ilorin
Authors: Adeogun A. G.
Published: April 2022

Watershed delineation is a required step when conducting any spatially distributed hydrological modelling. The prediction of water quality parameters in a basin entails delineation of watershed into different number of sub-basins. Thus, this research evaluated effects of watershed delineation on the prediction of water quality parameters in Gaa Akanbi area of Ilorin, Kwara state, Nigeria. The objectives are to model and predict water quality parameters in the watershed; delineate the selected watershed in various numbers of sub-basins and study the effects of watershed delineation in the prediction of water quality parameters of the basin. For proper implementation of this study, Geographical Information System (GIS) software, physically based watershed model – Soil and Water Assessment Tool (SWAT) and other data processing software were used. Since the model is physically based, the surface properties (i.e. Digital Elevation Model (DEM), stream network, digital soil map, digital land use and land cover map, climatic and hydrological data) served as input in the model. The model was daily for a period of 30 years (i.e. January 1991 to December, 2020). The results showed that the watershed was successfully delineated to 3,7,11,21,32,53 sub-basins. Also, it was noted that the predicted values of water quality parameters (Nitrate, organic phosphorus and sediment concentration) are directly proportional to increase in the number of sub-basins delineated in the watershed.
Hydrochemistry and Quality Assessment of Surface Water in Oba Dam, Ogbomoso, Southwestern Nigeria
Authors: Ogungbesan,  , Sanni K. A.
Published: April 2022

Hydrochemistry of the surface water in Oba Dam, Ogbomoso was investigated to determine the chemical characteristic and evaluate the water quality for drinking, domestic and agricultural usage. Twenty selected water samples collected at different points within the reservoir were analysed for pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Total Hardness (TH) and major ions (Na+, K+, Mg2+, Ca2+, Cl-, NO3-, SO42-, HCO3). The pH values (6.5-7.9) of the samples suggest circumneutral to weakly alkaline nature of the water in Oba Dam. The cations are dominantly Na+ and K+, while the anions are mainly NO3-, Cl- and SO42-. The plot of the chemical data in Piper diagram revealed the water samples as Na-K-Cl water facie suggesting that the water chemistry is being controlled mainly by anthropogenic inputs. Comparing the analysed water samples with WHO and Nigerian water quality standards shows that all the chemical parameters were within the desirable limits for drinking purpose. Similarly, the computed water quality index (WQI) values (15-21) for the studied water samples suggest excellent quality for drinking and domestic purposes. Calculated parameters like sodium adsorption ratio (SAR), percent sodium (%Na) and Keller index (K1) reveal that most of the analysed water samples are suitable for irrigation usage. However, higher Na+ content of few samples restrict the suitability for irrigation purposes. Therefore, this calls for regular monitoring of sodium contents to ascertain suitability for agricultural irrigation.

Authors: Lamidi N. A
Published: April 2022

In Nigeria recently, less-used timber species have been introduced into the main stream of timber markets, as a relief for over-exploitation of well-known species that are going into extinction due to over-exploitation for construction purposes. This study successfully classified four timber species grown in Nigeria into different strength classes in accordance with EN338, such as Ako-(Brachystegia eurycoma), Ara-(Pterocarpus erinarceus), Obobo-(Guarea cedrata) and Epuu-(Ricinodendron heudelotii) timber species. These timbers were obtained from famous timber market in Ibadan, southwestern Nigeria. All timber specimens used for physical and mechanical tests were prepared and tested in accordance with EN 13183-1 and EN 408 for structural timber. Four- point bending test was used for determining the bending strength and modulus of elasticity of each specimen using Universal Testing Machine. Characteristic values of the bending strength, modulus of elasticity and density were determined. The average moisture content of Ako, Ara, Obobo and Epuu were 11.78, 12.71, 23 and 24 %, respectively. Timber classification was conducted after properties values adjusted to 12 % moisture content as specified by EN 384. For density, Ako had the highest of 747.26 kg/m3 density followed by Ara and Obobo and Epuu had the lowest density of 481.71 and 477.15 kg/m3and also assigned to strength classes D 50, D 24, D 18 and C 16 respectively, in accordance with EN 338.

Published: April 2022

This paper examined the impact of particulate matter (PM) along the Ibadan-Ilorin highway of Nigeria. The study was conducted in Ogbomoso-section of Ibadan-Ilorin highway of Nigeria at three different locations for the wet and dry seasons. The GT-321 particle counter was used to measure the PM. It has five selectable size ranges of 0.3, 0.5, 1.0, 2.0, and 5.0 micron. The result of investigation showed that PM0.3 had highest percentage concentration values (87 – 96%) in all the selected location and in both seasons. The results of the research work showed that selected location and season had impact on the emission rate of the particle. All the selected sizes of PM had values more than ISO classes 1 -7 maximum concentrations limit. The study concludes that transport-related pollution is indeed significant within the study area with possible severe health consequences.
Improving Model Selection in Deep Supervised Transfer Learning Under Homogeneous Setting
Authors: Omondiagbe Osayande Pascal , MacDonell Stephen G. , Licorish Sherlock
Published: April 2022

In traditional machine learning environments, the use of non-parametric error estimation to set the discriminative threshold of a classifier to achieve the best accuracy is very effective. This method is not effective in a transfer learning environment because it is only reliable when both the training and testing data have similar distributions which is not the case in a transfer learning setting. Although the use of control variate techniques has been proposed to exploit the information about the error in the training sample to reduce the error in the test sample, this method yields a finite variance and the model uncertainty is not distributed among the variance. In this paper, we proposed and test a new transfer learning validation method called control linear minimum mean-squared error (CLMMSE) for source model selection under homogeneous transfer learning settings with the absence of an adequate pre-trained source model. Our approach adopts the Bayesian linear minimum mean-squared error (LMMSE) and integrates the idea of importance sampling into a control variate approach to provide an accurate estimate for the LMMSE that is then used to select the optimal source model. By combining importance sampling with the control variate technique to reduce further the variance, we can achieve a much tighter bound with the LMMSE. This approach reduces the risk in the target domain under data shift. Experimental results on synthetic data under two data shift settings demonstrate the efficacy of our approach. A further experiment on two real-world datasets shows that we were able to improve the accuracy of two state-of-the-art models tested; Bert (0.94\% to 65\%) and CodeBERT (1.82\% to 18.2\%) when compared to using previous selection methods.
Characteristic Mode Design of Dual-Band Multistate Tunable Absorber Based on Programmable Flexible Metasurface
Authors: Li Mengmeng
Published: April 2022

Theory of
characteristic modes (TCM) is
applied to the design of a programmable flexible metasurface (PFMS) to achieve
its multistate tunable microwave absorption. The designed metasurface consists
of two layers. The first layer is a very thin polyimide (PI), on which unit
cells consisting of two trapezoidal patches
symmetrical along the central
bias microstrip are printed. The second layer is grounded polyvinyl chloride
(PVC) substrate to maintain the flexibility of the designed structure. The TCM
is used to analyze and understand the modal behavior of the unit cell, which provides
clear underlying electromagnetic (EM) physics to guide us how to load
positive-intrinsic-negative (PIN) diode as a tunable resistance to achieve variable
absorption states. The designed PFMS absorber have been fabricated and experimentally verified on
the flat and cylindrical foams, respectively. Good agreements can be found
for both planar and cylindrical metasurface structures between full-wave simulations
and measurements. Less than -10 dB reflectivity is achieved from 3.6 to 10.7 GHz (99%). The mimicry of
time-varying scattering cross section (SCS) is further realized through
real-time coding PFMS absorber, which can be precisely tuned from -30 dB to 0 dB
with a step of 1.5 dB at 5.5 GHz and 10.4
GHz, respectively.
Investigation of a Deep Learning based Brain-Computer Interface with Respect to a Continuous Control Application
Authors: Strahnen Manfred , Kessler Philipp
Published: April 2022

In this paper we report on our investigations on the use of a Deep Learning based brain-computer interface in the context of a continuous control application. A continuous control application is an application where a Deep neural network (DNN) is supposed to recognize defined motor-imagery related neural states from continuously measured EEG data stream and to initiate corresponding actions. Decisive for the quality of such an application is the achieved response time of the system, which means the time it takes to detect a certain motor-imagery induced neural state, as well as the state detection time, which means the time duration for which this neural state is recognized. Our investigations show that the neural patterns in the 0-8 Hz low-frequency band are essential for a short response time and that the patterns valid in the 8-30 Hz frequency band should be used to achieve a good state detection time. We show that both parameters, response time and state detection time, can be significantly improved when so-called cropped training method is used to train the deep neural net. Reaching a short response time and a good state detection time is significant for most continuous control applications. To the best of our knowledge, this is the first time the use of cropped training to optimize a continuous control application has been investigated.
Fixed-Frequency PWM Control and Stability of Series-Stacked Buffer for 2ω-Power Decoupling
Authors: Mukhopadhyay Anwesha , John Vinod
Published: April 2022

Active second-harmonic (2ω) filters have become an integral technology for single-phase power converters in high power density designs. The series-stacked buffer (SSB) has emerged as an attractive topology among the existing solutions due to its low power, high efficiency, and compact design. However, one of the challenges in adopting SSB lies in its control, where conventionally hysteresis current control has been adopted. This results in a wide variation in the switching frequency, making the digital control implementation and filter design complex. On the other hand, fixed-frequency pulse-width modulation (PWM) control necessitates developing a model for the systematic controller design to ensure stability and desired filtering performance. The assumption of SSB modelled as a second-harmonic current source, independent of the dc bus circuit components, fails to capture the dc bus loading effect on the SSB. In this work, a dynamic model of SSB is eveloped where the main dc bus and its passive elements are taken into account. The derived model gives a systematic procedure for the controller design while ensuring the desired 2ω filtering. The stability limits and parameter sensitivities of the model are studied analytically and in simulations. The analytical model is validated, and the proposed controller performance and stability limit are verified experimentally on a hardware prototype.

Authors: Hafiz Khandaker Nusaiba , Haque Khandaker Foysal
Published: April 2022

Deep Learning, especially Convolutional Neural Networks (CNN) have been performing very well for the last decade in medical image classification. CNN has already shown a great prospect in detecting COVID-19 from chest X-ray images. However, due to its three dimensional data, chest CT scan images can provide better understanding of the affected area through segmentation in comparison to the chest X-ray images. But the chest CT scan images have not been explored enough to achieve sufficiently good results in comparison to the X-ray images. However, with proper image pre-processing, fine tuning and optimization of the models better results can be achieved. This work aims in contributing to filling this void of the literature. On this aspect, this work explores and design both custom CNN model and three other models based on transfer learning: InceptionV3, ResNet50 and VGG19. The best performing model is VGG19 with an accuracy of 98.39% and F-1 score of 98.52%. The main contribution of this work includes: (i) modeling a custom CNN model and three pre-trained models based on InceptionV3, ResNet50, and VGG19 (ii) training and validating the models with a comparatively larger dataset of 1252 COVID19 and 1230 non-COVID CT images (iii) fine tune and optimize the designed models based on the parameters like number of dense layers, optimizer, learning rate, batch size, decay rate, and activation functions to achieve better results than the most of the state-of-the-art literature (iv) the designed models are made public in [1] for reproducibility by the research community for further developments and improvements.
Ranking top-k trees in tree-based phylogenetic networks
Authors: Hayamizu Momoko , Makino Kazuhisa
Published: April 2022

Tree-based phylogenetic networks provide a powerful model for representing complex data or non-tree-like evolution. Such networks consist of an underlying evolutionary tree called a "support tree" (also known as a "subdivision tree") together with extra arcs added between the edges of that tree. However, a tree-based network can have exponentially many support trees, and this leads to a variety of computational problems. Recently, Hayamizu established a theory called the structure theorem for rooted binary phylogenetic networks and provided linear-time and linear-delay algorithms for different problems, such as counting, optimization, and enumeration of support trees. However, in practice, it is often more useful to search for both optimal and near-optimal solutions than to calculate only an optimal solution. In the present paper, we thus consider the following problem: Given a tree-based phylogenetic network N where each arc is weighted by its probability, compute the ranking of top-k support trees of N according to likelihood values. We provide a linear-delay (and hence optimal) algorithm for this problem.
作品 『壁』における の表象 - 安 公房はその文学に をどう描いたか / Representation of food in the collection of works Kabe: How Abe Kōbō wrote about food in the literature
Authors: Sasaki Yuki
Published: April 2022

This paper aims to examine the way "food" is depicted in “Kabe (The Wall)” (1951) written by Abe Kōbō. “Kabe” is Abe's first collection of works, and it consists of three parts: “S.Karuma-shi no Hanzai (The Crime of S. Karma)” (1951), “Akai Mayu (The Red Cocoon)” (1950), and six other works. Based on discussions in previous studies, I first aimed to clarify where Abe's "consistent intention" in his "Postscript" can be found from the perspective of quantitative text analysis using KH Coder. Then, I chose "food" as one of the indicators to support the worldbuilding and the actions of the characters in the work. I pointed out that the variety of both food and drink is limited, also there are no significant descriptions of taste, and that it can be inferred that what people eat is divided according to their positions in the story. In “Kabe”, the description of "food" is used as a trigger for the characters to move on to the next action.

Published: April 2022

The study aimed to profile and quantify sugars and organic acids metabolites in carambola, June plum and otaheite fruits during three different “on tree” stages: immature, green-mature and ripe stages. Metabolites were profiled and quantified by gas chromatography-mass spectrometry (GC-MS). Results showed that glucose, fructose, galactose, arabinose, and the sugar alcohol myo-inositol were detected in all fruits, while sucrose was detected in carambola and June plum only. Organic acids identified in all fruits were malic acid, citric acid, propanoic acid, and acetic acid. Comparatively, June plum showed the highest content of total sugars and carambola the lowest, while the highest total in organic acids content was found in otaheite and the lowest in carambola. On the other hand, most sugars increased during ripening of the three fruits, while organic acids decreased. Total sugars increased by 37%, 8% and 46% in ripe carambola, June plum and otaheite, respectively. Total organic acids decreased by 20% and 49% in ripe carambola and otaheite, while they slightly increased by 3% in ripe June plum. Furthermore, sugars/organic acids ratio in all fruits increased during maturation and ripening stages. Principal component analysis (PCA) showed two main groups of highly scoring metabolites, while the hierarchical cluster analysis (HCA) showed that the metabolites were grouped into three main clusters. Conclusively, results showed that glucose, fructose, malic acid and tartaric acids were the key marker metabolites of the maturation and ripening stages of the three fruits.

New spelling: debatable issues
Authors: Eysmont Yuliya
Published: April 2022

The legal document of the Cabinet of Ministers of Ukraine, which approved a new version of the "Ukrainian spelling", was analyzed. Attention is paid to the work of the Ukrainian National Commission on Spelling, which has developed the main language document of the state. The history of its formation during the independence of Ukraine is covered. Emphasis is placed on editing electronic abstract resources of the Vernadsky National library of Ukraine, taking into account the rules of the new edition of "Ukrainian spelling". Its main changes are considered. Particular attention is paid to the most controversial: spelling variations, changes in individual words, spelling words of foreign origin, and so on. The rules of writing compound words with the first regularly used foreign language component are studied. Innovations in the writing of femininities are highlighted. Attention is paid to individual cases of spelling violations, which occur most often. Ways to improve the editing of electronic resources of the Vernadsky National library of Ukraine are proposed. The significance of the Abstract Database "Ukrainika scientific" in the domestic and world information space is revealed. The role of the group of editors of the Library in the professional preparation of quality materials for its daily replenishment is determined. It is emphasized that scientific editing of the information array of the Abstract Database "Ukrainika scientific" requires compliance with domestic and international standards for the submission of information. It is unacceptable to ignore such main ethical principles of the editor as meticulous and thorough verification of the original sources of spelling of digital data, scientific and technical terms, units of measurement, use of names and dates, design of the reference apparatus of the publication, compliance with the symbols established by the standard in scientific and normative literature. It is emphasized that the professional filling of the domestic information space with quality abstract texts will positively affect the efficiency of their search by readers and increase the scientific value of electronic abstract resources of the Vernadsky National library of Ukraine.
Native advertising and periodicals: touch points
Authors: Bulakh Tetiana
Published: April 2022

The article describes the essential characteristics, hallmarks and benefits of native advertising. It is noted that it is created by employees of editorial offices, not advertising agencies, which is why the format and style of presentation of the material does not differ from other publications of the resource and meets the expectations of the target audience.
The conditions of its occurrence and the reasons for the increased attention of marketers to this type of advertising are now described. It is noted that this type of advertising does not irritate users, because it contains useful or interesting information; does not fall into the so-called zone of banner blindness; is not blocked in the Internet environment, because it is an informative, informative material that is not identified as advertising; contains information of various types: text, video, links, etc., which diversifies the presentation of the material.Effective native advertising must meet the needs of the target audience and the format of presentation of the material on the resource in order to be perceived as an organic part of it. It should perform the same functions as other materials: news — on the news site; games — in game applications; articles, videos, tests — in electronic publications, etc. — but at the same time clearly separated from other editorial materials.
Emphasis is placed on the expediency of using native advertising opportunities in promoting electronic publications. The experience of using native advertising in the publishing sphere is analyzed.

Authors: Sarker Dr. Shaoli , Azam Dr. A.Z.M. , Quaderi Dr. Humaira Rafiqa
Published: April 2022

Background: An electromyogram (EMG) measures the electrical activity of muscles when they're at rest and when they're being used. On the other hand, nerve conduction study (NCS) is a medical diagnostic test used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body. Both are used to diagnose the status of neuromuscular disorders even in children. Aim of the study: The aim of this study was to assess the findings of electromyogram and nerve conduction study in children with neuromuscular disorders. Methods: This retrospective, observational study was conducted in the department of Paediatric Neuroscience, Dhaka Shishu Hospital & BICH, Dhaka, Bangladesh during the period from January 2010 to December 2016. In total 65 suspected children with neuromuscular disorders were selected as the study subjects. After elaborating the history taking and physical examination a provisional diagnosis was made and sent for NCS and EMG to trained personnel at Bangladesh Protibondhi Foundation along with other necessary investigations. All data were recorded and the “clinical and etiological” profile was correlated with the neurophysiologic findings retrospectively. Results: As investigation reports of EMG, among all participants, we found normal findings in 21 participants. Besides these, a variety of SMA and/or late-onset SMA were found in 16 participants. Moreover, diffuse fibrillation, biphasic complex, repetitive spontaneous discharge was found among 6 participants. On the other hand, as per the investigation reports of NCS among all the participants, the normal finding was in 34 participants. Besides this low amplitude CMAP and SNAP, low amplitude CMAP, variable sensory conduction velocity, and slow conduction velocity with temporal dispersion were found in 3, 6, another 3, and 4 participants respectively. The compatibilities of electrophysiological diagnosis were found at 68% for detecting neurogenic disease and 71% for detecting myogenic disease. On the other hand, the compatibilities of the Nerve Conduction Study were found 46% for detecting neurogenic disease and 50% for detecting myogenic disease. Conclusion: NCS and EMG are crucial investigations to reach confirmation as well as the exclusion of the diagnosis of neuromuscular disorder in children.
Enhancing Effectiveness of E-Learning: Lessons from Technology Adoption Model
Authors: Kumar Dr. Sachin
Published: April 2022

A number of policies, missions and programmes have been initiated to facilitate e-learning enabled by information and communication technologies (ICTs) over recent years both by central as well as state governments in order to enhance effectiveness of teaching-learning process. However, tangible outcomes of such initiatives have been limited so far due to a number of factors especially in government institutions. While in some cases the core reason has been availability, accessibility, adequacy and quality of ICT tools, in many cases intention to use such technologies by teachers has been found conspicuous by its absence. The present paper uses the theoretical framework of the Technology Acceptance Model (TAM) to deduce relevant lessons. The objective is not to deliberate on the nuances of the model but simply to pick out a few relevant constructs in light of the author’s own experience of technology adoption in the context of schools and colleges of Himachal Pradesh. After briefly outlining the key tenets of TAM, the paper articulates the rationale for adopting this model and finally discusses key lessons for increasing acceptance of such technologies among educational stakeholders. Since COVID 19 has already created a rationale for adopting technology-enabled learning methodologies, the recommendations of this paper are likely to improve the efficacy and effectiveness of current and future initiatives.

Authors: Hieu Duong Thi Hong , Thien Nguyen Hoang
Published: April 2022

This study investigates the effectiveness of pedagogical courses and practicums in the A+B teacher education model at the University of Education, Vietnam National University, Hanoi. Most of the participants in the study said that they were implemented effectively, helping to equip students with what they need to become high school teacher s. However, the practicums at the University of Education are still in need of innovation when compared to the corresponding programs in many other countries. The implementation time of the A+B teacher education model has only been around a decade, so it is necessary to make continuous adjustments for the betterment of this model. The research results not only help stakeholders in the reform of teacher education at the University of Education, but also serve as reference information for other institutions in the process of innovating teacher education programs and models, particularly when it comes to pedagogical courses as well as practicums.

Placenta accreta is a rare condition. Its incidence is constantly increasing due to the increasing number of caesarean sections (multiplied by four over the same period).Placenta accreta is responsible for major maternal morbidity and mortality. Targeted ultrasound, in the presence of risk factors, is relevant for this diagnosis. Patients with at least one uterine scar and a previous placenta previa represent a population at risk whose placenta should be examined during screening ultrasound with the full attention of the operator. The smallest diagnostic doubt should lead the practitioner to refer the patient for expert ultrasound examination. Current challenges include early detection of placenta accreta in the first trimester, prediction of the degree and extent of placental villi invasion, and prognosis assessment.

COVID-19 has lately emerged as one of the most difficult pandemics of the twentieth century, with lethal consequences and a high rate of replication. It emphasizes the critical importance of developing effective vaccines to prevent virus infection, early and rapid diagnosis using high sensitivity and selectivity diagnostic kits, and effective antiviral and protective therapeutics to reduce and eliminate viral load and tissue damage-related side effects. As a result, non-toxic antiviral nanoparticles (NPs) are being developed for therapeutic use in the prevention and treatment of COVID-19. Nanoparticles have shown considerable promise in the development of nano vaccines to combat viral diseases. In this paper, we look at the potential of nanoparticles as a medicine or as a platform for drug and vaccine repurposing and development. Meanwhile, sophisticated virus detection methodologies based on NPs will be detailed, with the goal of inspiring scientists to develop cost-effective Nano platforms for prevention, diagnosis, and therapy.

Background: Despite playing an essential role as micronutrients, when exposed to an excess level, heavy metals can augment the risk of potential health diseases among humans and animals. Due to environmental degradation and food adulteration, many people are becoming the victims of those diseases by ingesting heavy metals from those food sources. Eggs are one of the principal sources of proteinaceous food and eggshells are also a good source of calcium, therefore, it is necessary to estimate the frequency of heavy metals as the poultry feeds, nowadays, are contaminated with heavy metals. Materials and Methods: Five types of egg samples were collected from the Jahangirnagar University area including indigenous, white and brown layer chicken eggs, duck eggs, and quail eggs. The concentration of Pb, Cd, Cr, Cu, Fe, and Zn was estimated both for egg contents and eggshells (10 samples) by atomic absorption spectrophotometry compared with the standard curve. Estimated daily intake (EDI), Target hazard quotient (THQ), and Hazard Index (HI) were also calculated to observe whether egg intake possesses any health hazards or not. Results: Among all the trace elements estimated, the highest concentration was 35.36±0.4 (Zn) in white layer chicken eggs, and for eggshells, the highest concentration was 0.69875±0.082 mg/kg (Fe) in Quail eggshell. Except for Fe, Pb was relatively higher compared to other elements in eggs, the amount of Pb was the highest in Quail eggs (0.486±0.09 mg/kg). All the six elements were also within the acceptable range in eggshells where the amount of Pb was the highest in Brown layer eggshells, and Cu and Zn were the highest in indigenous eggshells. Cd and Cr were below the detection limit for all types of eggshells. Estimated daily intake (EDI), Target hazard quotient (THQ) and Hazard Index (HI) values indicated that intake of eggs does not possess any health risk. Conclusion: Interestingly, the heavy metal concentration of our samples belongs within the PTDI and USEPA limit. Therefore, based on our study, all egg samples were safe considering the average egg ingestion in our country. If the average egg consumption rises, people might be at risk for higher Pb consumption through egg intake.

Tooth loss is, for the majority of patients, a strong physical and psychological disorder. The objective of this study was to evaluate the individual perception of dental aesthetics among patients received for joint prosthetic rehabilitation in the prosthesis department of the CHU-OS of Bamako. This was an epidemiological, descriptive and prospective study. The survey lasted 5 months, from April to August 2013. The population studied is made up of all the people seen in the prosthesis department. The variables studied were socio-demographic (sex, age) and clinical variables (reason for consultation, color, shape and position of teeth, personal appreciation of aesthetics, smile identification, patient satisfaction). The data obtained were entered and analyzed with SPSS version 20 software and processed with Word 2013 software. We examined 218 patients and the distribution according to sex showed a predominance of women with 67% with a sex ratio of 0.49. The study highlighted the youth of our population with 34.86% of people who are between 25 and 34 years old. In this study, white and well-positioned teeth are the dental aesthetic criteria most sought after by patients with respectively 91.3% and 54.6% of cases considering the position of the tooth always in association with the color as an important element in the aesthetics of a smile. The disability of edentulism opens up a psychological dimension that the practitioner must understand. It is a global care of the patient with his doubts and anxieties.
