Features of the Peaceful Settlement of Disputes in Arbitration
Authors:   Voronezh State University, Nosyreva Elena I.
Published: April 2023

The article analyses the possibilities of reconciliation of the parties directly during the arbitration proceedings or in connection with it. Attention is focused on how it differs from the regulation of the peaceful settlement of civil disputes in the courts. The current legislation on arbitration, the rules of Russian permanent arbitration institutions and foreign arbitration centres that have the right to administer arbitration in Russia are analysed in connection with the role of arbitrators in reconciliation of the parties, the conclusion of a settlement agreement, including those made after the completion of arbitration, the issuance of a decision on agreed terms, using the mediation before arbitration or in the course of it, the possibility of combining the role of the arbitrator and the mediator. Attention is drawn to the main attractive feature of legal regulation — an opportunity for the arbitral tribunal to make a decision on agreed terms, which allows not only to resolve the dispute based on the mutual interests of the parties, but also to ensure the enforceability of the agreements reached.
Settlement Agreement in Public Law Cases
Authors:   Institute of State and Law of the Russian Academy of Sciences, Mihailova Ekaterina V.
Published: April 2023

The article is devoted to the search for a criterion for the applicability of a settlement agreement in matters of a public law nature. The dual nature of the settlement agreement is shown, combining both substantive and procedural features. The properties of a settlement agreement as an act of public, procedural law arise at the time of its approval by the court — however, at present, the legislation does not contain an answer to the question of which cases are subject to settlement and which are not. The author’s criterion for determining the admissibility of a settlement agreement in public law cases is proposed: the criterion of abstract or specific public law enforcement. The issues of concluding a settlement agreement on certain categories of cases of a public law nature, as well as on cases that combine both imperative and dispositive legal regulation, are considered.
Judicial Scrutiny of Amicable Agreements: Limits and Restrictions
Authors:   Russian State University of Justice, Fokina Marina A.
Published: April 2023

Issues of judicial control over the result of conciliatory activities of the parties are analysed. The limits of the court’s control activities are determined when it approves the settlement agreement. The legal nature of reconciliation outcomes is explored in the context of specific types of conciliatory procedures: mediation, negotiation, judicial mediation. As a result of an analysis of doctrine and judicial practice, the author concludes that it is advisable to transfer the authority to certify and examine the results of any conciliatory procedures to a notary.
Sustainability Performance Frontiers
Authors: Leseure Michel
Published: April 2023

When the concept of strategic trade-offs was introduced by Skinner in 1969, an intense academic debate followed. On one hand, World Class Manufacturing proponents rejected the idea whilst others recommended the careful consideration of trade-offs when designing production systems. Today, history repeats itself, and the same debate exists in the field of sustainable operations management, with some researchers documenting trade-offs between economic and environmental performance, and others rejecting this view. This paper shows how this debate has profound implementation implications: the first view calls for incremental improvements, whereas the latter calls for radical innovation. This paper combines the behavioural theory of the firm with Schmenner and Swink's (1998) theory of performance frontiers to define sustainability performance frontiers. These frontiers define legitimate managerial boundaries for searching for sustainability and remove the perceived conflict between the two views of sustainability trade-offs.
Studying Modern Formula 1 Front Wing at Low Cornering Speeds
Authors: P. Nimje  , R. Kakde
Published: April 2023

A simulation-based study of three different types of front wing designs used in the modern Formula 1 cars was done. The study mainly focuses on the aerodynamic forces that a Formula One car generates mainly the Downforce, the Drag force, & the Lateral force at low cornering speeds. These forces were studied in detail & taking a closer look at how they migrate during the dynamic conditions the car is thrown at various Side Slip (Yaw) Angles, these results were compared with the wing Scuderia Ferrari used in the 1998 formula 1 championship to better understand the inherent problems faced in those previous designs. A brief study of the flow field & flow lines was conducted along with the vortex generation for all three wings. Vortex formation and management is a prominent part of research being carried out for a formula 1 car, so a brief study on the phenomenon of vortex generation & Y250 vortex formation was also carried out. A test on ride height and vorticity was also studied when the ride height was varied and the values were analysed. A study on the effect of the flow field of the upper element on the lower element was carried out where the 5th element was removed from each of the three wings & the effect on the downforce & drag value was analysed along with the pressure field.

Authors: Nishanth Krishna  , Raj Purohit  , J.S. Rohit  , Avasarala Venkata Srivatsa  , Sharanbassappa S Patil
Published: April 2023

The world’s first automobile built by Karl Benz was powered by a single-cylinder four-stroke engine which was placed at the rear part of the three-wheeled chassis. Since then, the automobile industry has drastically evolved, especially four wheelers. Nowadays, three-wheelers are gaining popularity as they are more fuel efficient than four-wheelers while being more stable than twowheelers. The inherent cost advantages of a threewheeler also make them more affordable. Autorickshaws, having delta configuration, are extensively utilized in several Asian countries like India, Indonesia, Pakistan and others. But they are risky during braking in a turn due to a single front wheel. Alternatively, a tadpole type three-wheeler is safer in braking in a turn and provides better steering control. This three-wheeler configuration also provides better aerodynamic design. They have been recently adopted in European countries for personal mobility and logistics. Therefore, the paper analyses the stability of a Tadpole type three-wheeler based on various standard simulation tests such as Constant Radius test, Acceleration test and Double Lane Change test. These tests provide various results such as Steering Angle, Understeer behaviour and Longitudinal Acceleration where information regarding handling characteristics can be studied. A comparison between Front Wheel Drive and Rear Wheel Drive configuration is carried out to arrive at a conclusion for selecting the right drivetrain configuration. In order to achieve this, a Multibody Dynamics model is created using MSC Adams Car by assembling the various subsystems namely Front Suspension, Rear Suspension, Steering, Brakes, Body, Powertrain and Tires. Simulation results have been compared with existing literature for the verification of the model.

Published: April 2023

Aims. To consider factors associated with adverse outcome among hospitalized patients with moderate and severe COVID-19.

Materials and methods. Data from 345 case histories of adult patients hospitalized with moderate to severe COVID-19 were analyzed in a single-center retrospective study. Characteristics by sex, age, number of days from disease onset to admission to hospital, duration of hospitalization, duration of disease, population characteristics by medical history of comorbidities and self-medication, outcome of hospitalization and medical technologies used in hospital conditions were given for the whole cohort of patients. All parameters were analyzed using descriptive statistics methods. Qualitative variables are given in absolute (n) and relative (%) values with 95% confidence interval. Continuous variables were presented as median and quartiles. Risk factors for mortality were determined across groups using the χ2  criterion and odds ratio.

Results. There was no demonstrated effect of gender, degree of pulmonary tissue lesions on computed tomography data, or time of initiation of respiratory support on disease outcome. At the same time, the age older than 65 years as well as neoplasms, type 2 diabetes mellitus, dementia, Stage 3 arterial hypertension, chronic heart failure, coronary heart disease, myocardial infarction and stroke history, chronic obstructive pulmonary disease, bronchiectatic disease, urogenital diseases were the predictors of unfavorable outcome in patients with moderate and severe COVID-19 form. Prehospital use of antiplatelet agents, direct and indirect oral anticoagulants, drugs affecting the renin-angiotensin system, systemic glucocorticosteroids, antibiotics, antiviral drugs, and analgesics was associated with a decrease in the mortality rate in patients with moderate-to-severe COVID-19, as well as timely use of pronposition and transfer to intensive care unit.

Conclusions. Our findings are partially consistent with previous reports on the effect of risk factors on COVID-19 outcomes.

Girls Have Academic Advantages and So Do Boys: A Multicountry Analysis of Gender Differences in Early Grade Reading and Mathematics Outcomes
Authors: Fonseca Jodie , Bahrawar Laiba , Dubeck Margaret M. , Sitabkhan Yasmin , Cummiskey Christopher , Unadkat Devanshi
Published: April 2023

This paper contains a new analysis of gender differences in early grade reading and mathematics outcomes in 19 USAID-funded studies over the past decade from 14 locations in Africa, Asia, Latin America, and the Middle East. The paper addresses gaps in the literature related to learning patterns for girls and boys in lower- and middle-income countries and in early primary school. We analyzed the results from reading and mathematics assessments in grades 2 and 3, including differences in oral reading fluency (ORF) and quantitative comparison scores between boys and girls, as well as differences in score distributions by gender. In line with results from assessments in upper grades and in wealthier countries, we found that girls consistently outperformed boys in reading. In mathematics, boys slightly outperformed girls, although the differences were typically not large. Global experience has shown that patterns in poor performance become more entrenched the further learners progress through the grades, suggesting that early interventions for boys in reading and girls in mathematics could have long-term benefits. At the same time, both girls and boys typically score below expectations in the two subjects across countries, necessitating targeted strategies to improve outcomes for both genders early in their educational trajectories.

Además, los docentes con conocimiento bajo tenían una actitud negativa en un 70 % y el p - valor de posible asociación entre nivel de conocimientos y actitud sobre primeros auxilios fue igual a 0.419. Como conclusión, se deduce que no existe una relación significativa entre Nivel de Conocimientos y Actitud sobre primeros auxilios en los docentes. No obstante, se recomienda a las instituciones superiores formadoras de docentes incluir en su malla curricular el curso de primeros auxilios en todas las temáticas inmersas en el mismo.
A STUDY OF THE SOCIO-CULTURAL STRUCTURE OF THE HIJRAS COMMUNITY IN VARANASI, UTTAR PRADESH, INDIA
Authors: Kumar Govind
Published: April 2023

The hijras or the third are known as Hijra, Eunuch, Kinnar, Aravani, Kothi, Shiv Shakti, Jogtas etc. in India. The third gender has always been on the fringes of society. For a long time, they are fighting for their identity. Though they got their new identity as Third Gender in 2014, still they are socially excluded. Still, they are fighting with society for their acceptance. This struggle does not seem to end soon. Recently Kochi metro provided a job to the third gender but the newly employed had to face the problem. They had to arrange their lodging at some distance from the main city because society did not give them a place to live. Another report of the Study on Human Rights of Transgender in India revealed that only just 2% of Trans. people stay with their parents. These are just a few recent examples of their social exclusion. They are still struggling for their social identity. Now they are 4.9 lakhs in number (According to the census of 2011) so they cannot be ignored. Still, they are known as socially ‘others’. Now the question arrives why they are still socially excluded. There are so many misconceptions and myths about them from their birth to death. There are so many reasons behind them. Some of the reasons like their closed society and they hardly allow anyone to enter their circle/society. They used to live in separate places from society, their lifestyle is different, so people have different misconceptions about them. They have their communication behavior. Why there is a communication gap between them (third gender) and us (society) in this information age? This research paper is intended to study the social structure of the hijra community in Varanasi city, this may be used for further studies related to the social wellbeing of Hijras in India.
SEXUAL ASSERTIVENESS OF WOMEN IN KERALA
Authors: Beegam Shahanas , P.S Swathymol.
Published: April 2023

Sexual assertiveness is an important element in caring for oneself and maintaining sexual health in situations involving unwanted and unsafe sexual contact. In contrast, females lacking sexual assertiveness may be more likely to experience sexual dysfunction and to be coerced in sexual relationships (Alvarado SLL, Van Parys H, Jerves E, and Enzlin P, 2020; Zhang H et al., 2021 ). The present study was intended to translate the scale of Sexual Assertiveness of Women by Morokoff et al. (1997) into Malayalam. On the standardization procedure, some items lack discrimination power and difficulty index. The overall scale has good reliability (Cronbach’s alpha 0.81, split-half reliability 0.65) and validity. In addition, the study also aimed to examine the sexual assertiveness of women in Kerala. The study participants were women who are married or having a partner and those who are having frequent sex. The data was collected randomly from Kerala. The total sample size was 100. The statistical techniques used were descriptive statistics, independent sample t-test, and one-way ANOVA. On the whole, the sexual assertiveness of women in Kerala was low. The religion and education of women have a great role in determining sexual assertiveness.

Since the middle of the last century, the Algerian steppe vegetation has been in continuous decline, which could be subject to environmental constraints that go against the sustainable development of a fragile environment exposed to climatic variations. Good management of this environment would be based on understanding the mechanisms of tolerance of steppe plant communities to the rainfall variations of the territory where they live. In the present study, for four years (2019- 2022), during the spring season, under arid bioclimate in the central Algerian Laghouat steppe region (Mokrane site), the relative water content (RCW) and the accumulated proline content were measured in the fresh leaves of three plant species (R. raetam, A. armatus and A. pungens). Also, a climatic synthesis of the study site was carried out. The aridity index of the site was found to be 0.06, and annual rainfall differences > 150 mm have sometimes been observed. The site is characterized by 11 months of drought over the year. During the 04 years, 2019 was the rainiest year receiving 238.88mm precipitation. During the 04 years of measurement, RCW revealed the existence of significant differences (P<0.05) for each of the three species. In R. raetam, the RWC was between 18.6 and 49.6%; for A. armatus 12 and 33.31% and for A. pungens 12.04 and 77.42% respectively. Between 2019 and 2022, the proline content also showed significant differences (P<0.05) for each of the three species. In R. raetam it was between 0.13- 1.4 mmol/g FM, for A. armatus between 0.26 - 0.96 mmol/g FM and between 0.20 -1.12 mmol/g FM for A. pungens. Pearson correlations revealed that annual cumulative rains were weakly correlated with RWC, but the correlation was strong and in a negative direction with accumulated proline. These results demonstrated that adaptation of the three species to rainfall variations is based on a tolerance mechanism driven by proline synthesis.

The Spin of a Newborn Black Hole: Swift J1728.9-3613

Published: April 2023

The origin and distribution of stellar-mass black hole spins are a rare window into the progenitor stars and supernova events that create them. Swift J1728.9-3613 is an X-ray binary, likely associated with the supernova remnant (SNR) G351.9-0.9. An NuSTAR X-ray spectrum of this source during its 2019 outburst reveals reflection from an accretion disk extending to the innermost stable circular orbit. Modeling of the relativistic Doppler shifts and gravitational redshifts imprinted on the spectrum measures a dimensionless spin parameter of a = 0.86 ± 0.02 (1σ confidence), a small inclination angle of the inner accretion disk θ < 10°, and a subsolar iron abundance in the disk A
Fe < 0.84. This high spin value rules out a neutron star primary at the 5σ level of confidence. If the black hole is located in a still visible SNR, it must be young. Therefore, we place a lower limit on the natal black hole spin of a > 0.82, concluding that the black hole must have formed with a high spin. This demonstrates that black hole formation channels that leave an SNR, and those that do not (e.g., Cyg X-1), can both lead to high natal spin with no requirement for subsequent accretion within the binary system. Emerging disparities between the population of high-spin black holes in X-ray binaries and the low-spin black holes that merge in gravitational wave events may therefore be explained in terms of different stellar conditions prior to collapse, rather than different environmental factors after formation.
X-Ray-luminous Supernovae: Threats to Terrestrial Biospheres
Authors: Brunton Ian R. , O’Mahoney Connor , Fields Brian D. , Melott Adrian L. , Thomas Brian C.
Published: April 2023

The spectacular outbursts of energy associated with supernovae (SNe) have long motivated research into their potentially hazardous effects on Earth and analogous environments. Much of this research has focused primarily on the atmospheric damage associated with the prompt arrival of ionizing photons within days or months of the initial outburst, and the high-energy cosmic rays that arrive thousands of years after the explosion. In this study, we turn the focus to persistent X-ray emission, arising in certain SNe that have interactions with a dense circumstellar medium and observed months and/or years after the initial outburst. The sustained high X-ray luminosity leads to large doses of ionizing radiation out to formidable distances. We assess the threat posed by these X-ray-luminous SNe for Earth-like planetary atmospheres; our results are rooted in the X-ray SN observations from Chandra, Swift-XRT, XMM-Newton, NuSTAR, and others. We find that this threat is particularly acute for SNe showing evidence of strong circumstellar interaction, such as Type IIn explosions, which have significantly larger ranges of influence than previously expected and lethal consequences up to ∼50 pc away. Furthermore, X-ray-bright SNe could pose a substantial and distinct threat to terrestrial biospheres and tighten the Galactic habitable zone. We urge follow-up X-ray observations of interacting SNe for months and years after the explosion to shed light on the physical nature and full-time evolution of the emission and to clarify the danger that these events pose for life in our galaxy and other star-forming regions.

Stingless bees have a sophisticated system of chemical communication that helps conspecifics find food sources. In this study, we investigated whether Melipona beecheii foragers deposit a chemical mark on food to recruit conspecifics. Our results showed that foragers preferred to visit the feeders visited previously by conspecifics over clean feeders. We also found that foragers preferred visiting feeders baited with labial gland extracts over those baited with mandibular extracts or hexane. Labial gland extracts elicited higher forager antennal responses compared with those evoked by the mandibular gland extracts or hexane. Labial gland extracts and extracts from feeders visited by foragers contain a mixture of unsaturated hydrocarbons, followed by straight chain hydrocarbons and small quantities of esters. The main component is a mixture of alkene isomers C27:1.

Authors: Vlasenko Iryna , Davtian Lena
Published: April 2023

The humanitarian crisis significantly affects the provision of medical and pharmaceutical care to PWD, and makes it difficult to predict its availability and affordability. It was established that despite the military actions in Ukraine, the reimbursement system is experiencing both negative and positive trends. Negative trends are : an increase in drug prices, the amount of patient co-payments, and a decrease in the number of glucose-lowering drugs that are subject to full reimbursement. Positive trends are: an increase in the amount of reimbursement and the number of glucose-lowering drugs that are included in the system reimbursements, including at the expense of extended dosage forms. The analysis showed that the war led to the introduction of positive changes – to increase the number of glucose-lowering drugs that are subject to full compensation.

Hepatitis is an infectious disease typified by inflammation in internal organ tissues, and it is caused by infection or inflammation of the liver. Hepatitis is often feared as a fatal illness, especially in developing countries, mostly due to contaminated water, poor sanitation, and risky blood transfusion practices. Although viruses are typically blamed, other potential causes of this kind of liver infection include autoimmune disorders, toxins, medicines, opioids, and alcohol. Viral hepatitis may be diagnosed using a variety of methods, including a physical exam, liver surgery (biopsy), imaging investigations like an ultrasound or CT scan, blood tests, a viral serology panel, a DNA test, and viral antibody testing. Our study proposes a new decision-support system for hepatitis diagnosis based on spherical q-linear Diophantine fuzzy sets (Sq-LDFS). Sq-LDFS form the generalized structure of all existing notions of fuzzy sets. Furthermore, a list of novel Einstein aggregation operators is developed under Sq-LDF information. Also, an improved VIKOR method is presented to address the uncertainty in analyzing the viral hepatitis categories demonstration. Interesting and useful properties of the proposed operators are given. The core of this research is the proposed algorithm based on the proposed Einstein aggregation operators and improved VIKOR approach to address uncertain information in decision support problems. Finally, a hepatitis diagnosis case study is examined to show how the suggested approach works in practice. Additionally, a comparison is provided to demonstrate the superiority and efficacy of the suggested decision technique.
Application of Fisher information to CMOS noise estimation
Authors: Pan Mingying , Feng Xiangchu
Published: April 2023

Analysis of the accuracy of estimated parameters is an important research direction. In the article, the maximum likelihood estimation is used to estimate CMOS image noise parameters and Fisher information is used to analyse their accuracy. The accuracies of the two parameters are different in different situations. Two applications of it are proposed in this paper. The first one is a guide to image representation. The standard pixel image has higher accuracy for signal-dependent noise and higher error for additive noise, in contrast to the normalised pixel image. Therefore, the corresponding image representation is chosen to estimate the noise parameters according to the dominant noise. The second application of the conclusions is a guide to algorithm design. For standard pixel images, the error of additive noise estimation will largely affect the final denoising result if two kinds of noise are removed simultaneously. Therefore, a divide-and-conquer hybrid total least squares algorithm is proposed for CMOS image restoration. After estimating the parameters, the total least square algorithm is first used to remove the signal-dependent noise of the image. Then, the additive noise parameters of the processed image are updated by using the principal component analysis algorithm, and the additive noise in the image is removed by BM3D. Experiments show that this hybrid method can effectively avoid the problems caused by the inconsistent precision of the two kinds of noise parameters. Compared with the state-of-art methods, the new method shows certain advantages in subjective visual quality and objective image restoration indicators.

Published: April 2023

This research work appertains to the acceptance sampling plan under the neutrosophic statistical interval method (ASP-NSIM) based on gamma distribution (GD), Burr type XII distribution (BXIID) and the Birnbaum-Saunders distribution (BSD). The plan parameters will be determined using the neutrosophic non-linear optimization problem. We will provide numerous tables for the three distributions using various values of shape parameters and degree of indeterminacy. The efficiency of the proposed ASP-NSIM will be discussed over the existing sampling plan in terms of sample size. The application of the proposed ASP-NSIM will be given with the aid of industrial data.

Impact of residential everyday urban spaces conception on children community play behavior and cognitive development: the case of Cairo and Paris
Authors: Elnesr Maya
Published: April 2023

This research was initiated with the objective of investigating the potential impact of urban space design on play behavior and child development. Two neighborhoods (in Paris and Cairo) with similar spatial typologies (garden, pedestrian pathways, assembly zone, courtyard, building buffers, and pockets), but with different spatial attributes forming different configurations, were investigated. The study relies on causal comparative survey and intrinsic case study approaches. Data collection was conducted through children behavioral observations on children aged from 5 to 12 , perceptual drawing activities and informal interviews with child-led walks. The children are from middle socio-cultural segments of both societies that helped in understanding children’s play in a variety of outdoor settings. The assembled data was analyzed within the shadow of Trialectic Space and Affordances theories to the two neighborhoods, where children perception to their lived ambiance was identified. Trialectic theory helps in comprehending the difference between the conceived space by designers, the perceive space by children, and the resulted lived space. Affordance theory helps to link the environmental characteristics and the users’ behaviors according to their capabilities. Based on the analyzed data, the study identified a set of specific spatial physical aspects and functional qualities “potentialities” associated to children experiences and their space preferences. The study recommended that urban planners should extract themes essential for creating “child friendly” environment.

In the context of urban transformation, children's mobility is a field of study in the social sciences that has been growing rapidly over the last twenty years. In this research, we aim to understand how children’s autonomy evolves during a “normative transition” from elementary (T1) to middle school (T2). Children’s autonomy is studied through daily independent travel, types of places visited as well as by observing children’s ability to deal with unexpected and unfamiliar situations. Based on a longitudinal Mobi’kids survey using mixed methods (GPS travel/stop data; data from prompted recall interviews with children), children’s autonomy (based on independent travel, types of places visited and the ability to deal with unexpected situations) was analyzed over two periods (T1, n=86 and T2, n=56). The results show differences in mobility habits between the suburban and city children (in both T1 and T2), but also the same evolution trend in terms of independent travel while attending middle school (T2). The normative transition seems to have a role in some travel patterns and consequently on a few coping strategies to deal mainly with unfamiliar contexts.

Analytical Modeling for Fabrication of Biomedical Pressure Sensors by Bulk Micromachining Technology
Authors: Gaiseanu Florin
Published: April 2023

This article presents an analytical modeling of the boron-diffused silicon layers used as a self-stop etching process for the fabrication of the silicon capacitive sensors for biomedical applications by bulk micromachining technology, a key process for an accurate control of the membrane characteristics. Analytical expressions are obtained describing the boron profiles after the diffusion from oxidizing (BBr3, B2O3) and non-oxidizing boron-nitride (BN) source, showing a very good agreement with the experimental data, and which obey two distinct universal curves, independent of diffusion time and temperature. These results are used to calculate the silicon etching rate and time by analytical relations, as a function of the depth and etching temperature in 10% and 24% alkaline-type solutions of KOH (NaOH, LiOH) or ethylene-diamine-based (EDP) solution, allowing an accurate control of the thickness of the silicon membrane and of the processing-induced stress, which finally determines the technical characteristics of the silicon capacitive sensors for biomedical applications.

Published: April 2023

Intelligent tutoring systems (ITSs) are computational learning support systems based on the use of artificial intelligence. These systems can be used to customize educational content, learning paths, interfaces, and feedback according to learners' current capabilities. Among the learners' capabilities, it is common to address three dimensions: cognition, affect, and metacognition. The first refers to information processing, the second to emotions during learning, and the third to the monitoring of cognition. This chapter, per the authors, introduces and discusses the meaning of metacognition, the architecture of ITSs, and how the ITSs could support metacognition, then mentions some journals and conferences about these systems, describes four successful application examples, and presents some recommendations and future research directions. It also proposes that this type of systems be grouped under the term metacognitive tutoring systems (MTS).
