Dumitru Chioaru, Avatarurile Lui Orfeu, Editura Univers, Bucureşti, 2021
Authors: Boldea Iulian
Published: February 2023

In his book entitled Avatarurile lui Orfeu (Orpheus’s Avatars), Dumitru Chioaru presents the two hypostases of the Orphism, the orphic and anti or post(orphic). Beginning his line of argument from the myth of Orpheus and crystallising his critical options with a hermeneutic perspective on the problem in question, Dumitru Chioaru manages to achieve a larger picture of the lyricism related to the orphic myth, by analysing the poetic works of thirty poets.

The Orphism’s hypostases are depicted by means of two exegetic methods, both used in an irreproachable manner (mythological criticism and hermeneutics). Dumitru Chioaru’s endeavour in the history of the universal lyricism and in everything which lyricism represents, in its multiple hypostases, proves the presence of a fine hermeneutist, attentive to everything which the paradigm of Orphism implies, a paradigm he manages to define by capturing it in some ample sentences, both clarifying and expressive.
Distortion Analysis for Programmable Analog Signals Generated Using FPGA
Authors: Hariton Anamaria , Zet Cristian , Foșalǎu Cristian
Published: February 2023

Practical applications in electrical engineering often deal with analog signals, but there are employed also digital circuits and microcontrollers. Sometimes it is easier or cheaper to improvise DA and AD converters instead of using dedicated ones. This paper is a comparative analysis of how accurate the analog signals can be generated from digital systems, like Field Programmable Gate Arrays (FPGAs) using only additional passive circuits. For this analysis, different FPGAs families were tested. Two alternatives of generating analog signals were considered in this study: PWM and R2R network. The analysis has been performed for a common frequency band, from 100 Hz to 30 kHz, using a virtual instrument for building an automated test system. At 10 kHz the PWM module obtains better THD values, reaching even 0.013% and at 30 kHz the R2R module obtains better THD values, reaching even 0.222%.
Connecting Analog and Discrete Nonlinear Systems for Noise Generation
Authors: Grigoraş Victor , Grigoraş Carmen
Published: February 2023

Nonlinear systems exhibit complex dynamic behaviour, including quasi-periodic and chaotic. The present contribution presents a composed analogue and discrete-time structure, based on second-order nonlinear building blocks with periodic oscillatory behaviour, that can be used for complex signal generation. The chosen feedback connection of the two modules aims at obtaining a more complex nonlinear dynamic behaviour than that of the building blocks. Performing a parameter scan, it is highlighted that the resulting nonlinear system has a quasi-periodic behaviour for large ranges of parameter values. The nonlinear system attractor projections are obtained by simulation and statistical numerical results are presented, both confirming the possible use of the designed system as a noise generator.
Science Curiosities Cabinet And The Chemical Showcase
Authors: Szydło Zbigniew A.
Published: February 2023

With the drastic reduction of the school chemistry teaching program in England in 1986, large quantities of apparatus and chemicals became redundant. The disused apparatus at Highgate School inspired the construction of a chemical showcase for pupils; this has encouraged pupils to develop a passion for chemistry. The idea of a “miniature museum” came from a visit to a local primary school in London, which had a beautiful science curiosities cabinet in one of its rooms. In both schools, sciences thrive, and are popular among pupils. Undoubtedly a display of assorted artefacts, which can be readily accessed by pupils, makes a significant impact on developing their interest in science. It is hoped that the story of these ventures will inspire teachers to make their own versions of these excellent and easily constructed educational facilities.
Eu-Topiile. Joc, Colecționare Și Multiplicitate în Construcția Posturală a Simonei Popescu
Authors: Sârbu Ștefania
Published: February 2023

The study aims to analyze the way in which the posture of the Romanian contemporary writer Simona Popescu is created, based on concepts in the field of postural analysis, as posture and ethos, theorized by Alain Viala and Jérôme Meizoz. With emblems as exuviae, Matryoshka doll, Rubikʼs cube, the image of the collage dilettante, or the one of postman Cheval, the self-image constructed, by discursive means, by Simona Popescu is one of the adult-child, who keeps childhood and youth as defining layers of the mature personʼs identity. The writerʼs fascination with Gellu Naumʼs figure, the subject of her doctoral research, is justified mainly by her interest in collage and by the possibility of using this technique as the instrument of construction of her figure as a writer (the account of her childhood is seen as an attempt to stage surrealism). The analyzed corpus highlights also as representative of Simona Popescu the collectorʼs figure – even the toy collectorʼs figure, for the analysis of which will be used Walter Benjaminʼs famous texts about childhood and dolls (Enfance. Eloge de la poupée et autres essais).
Parameters identification for a nonlinear partial differential equation in image denoising
Authors: Mourabit A. El
Published: February 2023

In this work and in the context of PDE constrained optimization problems, we are interested in identification of a parameter in the diffusion equation proposed in [1]. We propose to identify this parameter automatically by a gradient descent algorithm to improve the restoration of a noisy image. Finally, we give numerical results to illustrate the performance of the automatic selection of this parameter and compare our numerical results with other image denoising approaches or algorithms.
Space Maintenance of Premature Primary Tooth Loss - An Overview
Authors: Nedeljkovic Andrija , Petrovic Marijana , Andjelic Bojan
Published: February 2023

Replacement of deciduous teeth with permanent teeth is a physiological process, and as a consequence of early tooth loss in deciduous or mixed dentition, loss of space may occur. There is no doubt that the loss of space after the premature extraction of deciduous molars occurs, however, the width of the lost space and the need for their clinical use are still a topic that is up for discussion. This period is an indication for the designing and installation of space maintainers. The goal of therapy in such situations is to maintain the position of the deciduous dentition in the arch until the eruption of permanent teeth takes place and those teeth take their natural and correct positions. Depending on the method of fixation, space keepers can be fixed, cemented and mobile. These devices are divided by the way they function into active (enable the increase of space by their action) and passive. Space maintainers are a bit neglected, and they represent a very important clinical treatment whose use can bring a lot of benefits, both prophylactic and therapeutic. The development of biomaterials and digitalization in dental practice can direct us to modify and improve this therapeutic method.

Published: February 2023

Social media offers many offers to its users entertainment media, social media, life-styles media, business media, educational media. But despite the many attractions offered on social media there is danger. One social media user is a minor who is particularly susceptible to the dangers on social media. Thus was born the 27th 2022 year law on personal data protection, through which through these invitations it is hoped that children will be under the age of a minor and more fair protection from a child's parents. As for the method of research used in this study is normative-juridical. Studies have been found that birth rules regarding processing and the trial of the child's personal data should be subject to parental consent because the child is still vulnerable to social media hazards. But the application of child supervision in using social media is a challenge in itself because the parent of the child cannot possibly be ignorant of social media, therefore, in addition to the 27 year 2022 act on personal data protection, the child need to be given social media education so that the ease on social media can remain accessible to minors, More than that, a child's process for social media needs to be organized into an even more organized system, such as having a feature as creating an id card photo to join social media.

Published: February 2023

This paper pictures education changes into a technological system. Face to face class has to be limited because of the pandemic. In Indonesia, online learning is something new that needs adaptation to do because not all students are familiar with the system. Some students got some difficulties during online learning and students also have different views of this learning system. Emergency remote teaching (ERT) is meant to be a temporary shift from the normal modes of teaching. This takes what would have otherwise been face-to-face or hybrid teaching and transforms it to become digital education. The Mobile device can help the students continue their lessons through online classes because that is the alternative way to keep learning. Whatsapp Application can help students communicate and share knowledge with their teachers from a distance without face to face. Whatsapp application is then promoted as the alternative way in facing the remote learning situation. WhatsApp has become a shared platform that enhances accessibility, encourages cooperation, and intensifies motivation to take an active part in academic assignments.

Published: February 2023

Aim. To study pharmaceutical awareness of the population in the rational use of medicines using innovative marketing tools.

Materials and methods. The results of an electronic survey of visitors to pharmacies using questionnaires of the author’s social project “Important facts about medicines” implemented by pharmacies are presented. The data analysis was accompanied by the use of sociological survey methods, descriptive statistics, graphic analysis, grouping methods and generalization of data.

Results. Based on the data generalization the existing correlation between the level of involving pharmacy visitors in the project with the interest in obtaining important facts about medicines was found. According to the number of responses provided by visitors during the project implementation, it can be argued that the most attractive was the information about the impact of medicines while driving, and half as attractive were the facts about the peculiarities of using medicines for children. It was determined that the most general important facts about medicines were well-known for the project participants; on average 53 % of respondents had a sufficient level of awareness. Thus, the highest level of awareness was determined regarding the side effects in case of simultaneous use of medicines and alcohol; increased blood pressure in case of medicines containing caffeine; strict compliance with the patient information leaflet for taking medicines. A sufficient number of project participants (44 % of the total number of pharmacy visitors who responded) indicated that they were aware of the facts about the peculiarities of using medicines for children under one year of age. The level of pharmaceutical awareness of pharmacy visitors concerning important facts about the effects of medicines on the human body while driving was the lowest; it was 33% among all pharmacy visitors who responded. For example, pharmacy visitors were not aware of what antihistamines should not be taken by drivers.

Conclusions. Based on the analysis a high level of self-motivation of visitors to expand the range of important knowledge about medicines and the effectiveness of innovative marketing tools to create pharmaceutical awareness of the population in issues of the rational use of medicines has been revealed.

Key words: pharmaceutical information; pharmaceutical awareness of the population; responsible self-medication; social project.

Equity in HIV/AIDS management and prophylaxis: How free is the free ART program in India?
Authors: Wangjam Koko , Sharma Naresh Kumar
Published: February 2023

The concern for most public health policies and decision-makers is the equitable distribution of the nation’s healthcare resources. Also, in the public health care system, the primary aim is assuaging the burden of the disease. This study captures and evaluates some important health equity aspects with its relevance with the ART (Antiretroviral Therapy) program in India. The study is an exploratory and descriptive study based on secondary data. The sources of secondary data are published official reports from NACO (National AIDS Control Organization), United Nations AIDS Program (UNAIDS), World Health Organization (WHO) etc. The roll-out of the ART program in 2004 by the Govt. of India made a paradigm shift in the HIV/AIDS scenario in the country. “The adult HIV prevalence at the national level has continued its steady decline from an estimated level of 0.41% in 2001 through 0.35% in 2006 to 0.27% in 2011”. Equity in plain words means fairness. In the sense of health policy and HIV/AIDS studies, the reduction in prevalence rate equates to positive health equity. The enervation of HIV infection by taking ART drugs had helped in curbing the prevalence and the fact that it is provided free of cost has proven this program to be the epitome of distributive justice in public health.

Authors: Bhat K. A. , Malik G. M. , Akhtar S.
Published: February 2023

A new foliar disease was observed on a perennial weed Rumex crispus which grows extensively in orchards, pastures, hay crops, lawns and home gardens in Kashmir valley. Repeated Isolation of the pathogen from the infected leaves of Rumex crispus yielded the fungus which on the basis of Cultural and morphological characteristics showed a resemblance to Didymella sp. Pathogenicity was confirmed by the detached leaf technique as well as inoculating whole plants in pots. Precise confirmation of the identity of the pathogen was done by sequencing the reference genes using ITS1 and ITS4 markers and sequenced data was subjected to BLAST which showed 99.80 per cent similarity with Didymella rumicicola which was previously only reported in New Zealand on Rumex obtusifolius prior to this study. Host range, as well as bioherbicidal potential of this pathogen on hosts of five different families of cultivated crops along with Rumex plants, revealed that no disease incidence was found on host plant species of other families of cultivated crops, whereas,100% disease incidence and 80% severity were observed on Rumex crispus at 15 and 25 days after inoculation respectively. Physiological studies showed the newly isolated pathogen Didymella rumicicola showed the best radial growth on Potato dextrose agar at pH 6.5 and at a temperature of 25oC.

يهدف البحث إلى تسليط الضوء على متحف سامراء ودراسته تاريخيًا؛ كونه جزءًا من المدينة في العصر العثماني، وعماريًا كونه آخر ما تبقّى من السور، ومحاولةً منا اظهار أهمية المتحف وإرجاعه إلى سابق عهده وافتتاحه ليضمّ مقتنيات المدينة ، ومحاولة إلى عودة الاعمال التنقيبية فيها من خلال العمل الدؤوب للباحثين والمختصين في مجال الاثار.
A Pragmatic Study of the Use of Personal Pronouns in Joe Biden's Victory Speech
Authors: Taha Rayya Faiz
Published: February 2023

In fact, every word said by the politicians in their public speech cannot be chosen randomly. There are always different interpretations behind their choice of words.

     This paper is a pragmatic study that analyzes the use of personal pronouns by the politicians in general, and in Joe Biden’s, the president of the United States, victory speech after winning the presidential election, in particular. It tries to clarify the different purposes of the politicians, particularly Biden, behind their choice of the personal pronouns.

     In the introduction of this study, the researcher tries to present, define and clarify pragmatics and pronouns, with its types, more specifically the personal pronoun. Furthermore, the use of the personal pronouns in the political speech is explained followed by its pragmatic dimension. Then, some examples of the use of the personal pronoun, specifically I, we, you and they, in the American president's speech are presented and analyzed pragmatically. This study hypothesizes that any change of the use of personal pronouns by politicians change the connotation of that speech. The conclusion of this study proves this hypothesis.

This paper details the use of nanosecond repetitively pulsed discharges to attenuate combustion instabilities in a 14 kW swirl-stabilized methane/air combustor. The combustor exhibits large-amplitude pressure oscillations ranging from 1 to 4% of the mean pressure during which the flame exhibits bulk motion in each instability cycle, upstream and downstream, as revealed by high-speed chemiluminescence. Control is accomplished with an electrode comprising a pin anode at the centerline of the combustor, allowing a nanosecond spark to be generated in a region spanning close to the flame base, through the shear layers of the swirling flow and ending at the metallic combustor wall. The discharges are generated using 20 kV, 9 kHz pulses; and they correspond to about 120 W of mean power. This results in a suppression of the peak amplitude of the pressure oscillations by a factor of two to four, and 5 dB in the rms value. Using phase-averaged visualizations of the flame with and without plasma, we detail the sequence of flame motion in the course of the instability. With the plasma active, this reveals significant interactions between the flame and the plasma during the suppression. Finally, we present a state-space model of the thermoacoustic system, and we demonstrate open-loop control of the instabilities.
Shock Absorber Leakage Impact on Aircraft Lateral Stability During Ground Handling Maneuvers

Published: February 2023

Aircraft braking maneuvers are safety-critical on-ground motions that exhibit complex dynamics and significant dependence on system operating conditions. The fundamental interface between the aircraft and the ground is the landing gear. Among the landing gear components, the shock absorbers may be subject to gas leakage during their lifetime, which is an anomaly that could compromise the lateral stability properties of the aircraft on the operating regimes found during braking maneuvers. In this paper, an explicit link is established between main landing gear shock absorber leakage and aircraft lateral stability. To investigate lateral stability, a high-fidelity multibody nonlinear aircraft simulator is developed in a MATLAB/Simulink framework and validated against experimental data. To generate insight into the problem and to quantify shock absorber leakage impact on aircraft lateral stability, two simple but descriptive analytical models are also developed, each one on a different operating mode of the system. The analysis of the models reveals that shock absorber leakage can have a significant effect on aircraft lateral stability, especially at high velocities and highly damped nose wheel steering conditions. The models developed in this work may be used by aircraft control system designers to come up with more effective lateral stability controllers in the event of main landing gear shock absorber leakage.
Controllability Properties of Solar Sails

Trajectory design and stationkeeping of solar sails about a celestial body can be formulated as control problems with positivity constraints. Specifically, when reemitted radiation is neglected and the sail is modeled as a flat surface, which are reasonable assumptions for control purposes, the force generated by the solar radiation pressure is contained in a pointed convex cone of revolution with the axis in the sun–satellite direction. Therefore, classical approaches to infer controllability based on the Lie algebra rank condition do not apply to these problems. This study offers a novel condition to decide on controllability of control systems with positivity constraints. This condition is effective because it can be verified by solving an auxiliary convex optimization problem for which reliable numerical methods are available. A crucial ingredient of this approach is the theory of positive trigonometric polynomials. The practical interest of this condition is the assessment of a minimum requirement on the optical properties of the sail, which may be of use for mission design purposes.
Improved Generative Adversarial Network Method for Flight Crew Dialog Speech Enhancement
Authors: Chen Nongtian , Ning Weifeng , Man Yongzheng , Li Junhui
Published: February 2023

Traditional speech enhancement algorithms are only suitable for dealing with stationary noise, but the noise in the stage of flight is nonstationary noise, so the traditional method is not suitable for dealing with the noise in the stage of flight. This paper proposes a speech enhancement algorithm based on a generative adversarial network: Deep Convolutional–Wasserstein Generative Adversarial Network (DWGAN). Firstly, the model integrates the deep convolutional generative adversarial network and the Wasserstein distance based on the generative adversarial network. Secondly, it introduces a conditional model to improve the enhanced speech quality, and the spectral constraint layer is used to prevent the model from falling too fast and causing collapse. Finally, the L1 loss term is introduced into the loss function to reduce the number of training times and further improve the enhanced speech quality. The experimental results show that the intrusiveness of background noise and overall processed speech quality of DWGAN are improved by about 7.6 and 9.4%, respectively, compared with WGAN in the acoustic environment of simulated aircraft operation.
Edge-Enhanced Attentions for Drone Delivery in Presence of Winds and Recharging Stations

Published: February 2023

Existing variants of vehicle routing problems have limited capabilities in describing real-world drone delivery scenarios in terms of drone physical restrictions, mission constraints, and stochastic operating environments. To that end, this paper proposes a specific drone delivery problem with recharging (DDP-R) characterized by directional edges and stochastic edge costs subject to wind conditions. To address it, the DDP-R is cast into a Markov decision process over a graph, with the next node chosen according to a stochastic policy based on the evolving observation. An edge-enhanced attention model (AM-E) is then suggested to map the optimal policy via the deep reinforcement learning (DRL) approach. The AM-E comprises a succession of edge-enhanced dot-product attention layers and is designed with the aim of capturing the heterogeneous node relationship for DDP-Rs by incorporating adjacent edge information. Simulations show that edge enhancement facilitates the training process, achieving superior performance with less trainable parameters and simpler architecture in comparison with other deep learning models. Furthermore, a stochastic drone energy cost model in consideration of winds is incorporated into validation simulations, which provides a practical insight into drone delivery problems. In terms of both nonwind and windy cases, extensive simulations demonstrate that the proposed DRL method outperforms state-of-the-art heuristics for solving DDP-Rs, especially at large sizes.

System-level impingement cooling with cryogens has potential thermal applications in size-constrained, weight-constrained, and power-constrained or low-atmosphere environments by utilizing a phase change for enhanced heat transfer at cryogenic temperatures. In this work, an experiment capable of measuring the heat and mass flow of liquid nitrogen jets for variable impingement surface temperatures, mass flow rates, and jet geometries is developed. A boiling curve and other performance metrics are produced. A critical heat flux of approximately [Formula: see text] is observed.
