Direction of Korean Parent Education through Analysis of German Parent Education Activities
Authors:   Educational Research Institute, Park Seong-Hie
Published: March 2024

Parental education in Korea is understood as a consultative process that provides parents with the knowledge they need to raise their children, and it is difficult to find participatory parental education activities that prevent or resolve various conflicts. The death of a Seo Yi elementary school teacher and the assault on Yang Cheon-gu elementary school teacher in 2023 prove that the relationship between teachers and parents needs to be redefined in Korean education. Given this need for research, the purpose of this study is to analyze German parent education activities and gain implications for the direction of parent education in Korea. The research questions to achieve the purpose are: First, what are the macro, meso, and micro systems of parent education activities in Germany, where cooperation between parents and teachers is well established? Second, what is the direction of parent education in Korea? The research method was a literature review of parent education activities in Germany and the collected data were analyzed based on Bronfenbrenner's ecological system theory. As the results, this study suggested for Korea that the legal basis for parental education should be improved in the higher law, parental education autonomy should be guaranteed, a win-win partnership between teachers and parents should be promoted, and parental empowerment should be supported in order to activate parental education participation by public-private cooperation to ensure children's well-being.

Authors: Bercovitch Dayna , Reppas Rindlisbacher Andi , Ng Hillary , Mulvihill Sarah , Sum Brandon , Patel Sajan , Aitken Lyndsay , Marques Meagan , Aravind Gayatri , Salbach Nancy M.
Published: March 2024

Purpose:

To understand the impact of COVID-19-related closures of community-based exercise programs (CBEPs) on exercise participation, physical activity, and health of older adults with balance and mobility limitations; facilitators, and barriers to exercise and physical activity; and preferred support from recreation centres and healthcare providers.

Method:

This qualitative descriptive study involved semi-structured interviews with seven older adults (aged 50–76 years) with balance and mobility limitations, enrolled in CBEPs at a recreation centre in a suburban area in Canada prior to the COVID-19 pandemic. We conducted a thematic analysis.

Results:

One major theme, losing ground in the absence of structured exercise, was identified. Despite engaging in alternative at-home or outdoor activities, participants perceived a worsening of their balance and mobility, dissatisfaction with the extent of exercises and physical activity, and loss of social connectedness. Participants desired structured, individualized exercise resources, and frequent check-ins from exercise instructors to stay physically active during program suspension.

Conclusions:

Following CBEP closures, older adults with balance and mobility limitations from a single recreation centre perceived declines in physical and mental health, exercise participation and social interaction, and desired personalized exercises and communication from exercise instructors. The small sample size may have limited achievement of saturation.
Involving Physiotherapists in the Conduct of Research: A Mixed Methods Study of Physiotherapist Experiences, Perceptions, and Clinical Practice in a Research Project Using a Standardized Clinical Measure of Standing Balance
Authors: Sibley Kathryn M. , Roche Patricia , Jansson Ann , Niebuhr Rudy , Beauchamp Marla K.
Published: March 2024

Purpose:

The objectives of this study were to understand the experiences, perceptions, and clinical practice of physiotherapists involved in planning, data collection, and interpretation for a study using a standardized measure of standing balance (the Mini Balance Evaluation Systems Test [Mini BESTest]).

Method:

We conducted a concurrent mixed methods study. We conducted semi-structured interviews with five phsyiotherapists exploring perceptions and experiences. We administered questionnaires on study satisfaction, confidence, and intention to use the Mini BESTest six times during the study. We extracted use of the Mini BESTest on non-study patients from a patient database.

Results:

Physiotherapists administered the Mini BESTest for all 59 clinical study patients. Study satisfaction was high (median 80%) and increased over time ( p < 0.05). Physiotherapists described generally positive experiences. Confidence in ability to administer, score, and interpret the Mini BESTest increased (all p < 0.05), although perceptions of the Mini BESTest varied. Intention to use the Mini BESTest did not change and physiotherapists used the Mini BESTest on non-study patients on average 11 times during the clinical study (range 0–33).

Conclusions:

Involving physiotherapists in clinical research increased confidence and use of the measure with non-study patients.
Flash Bainite—Room Temp Stamping 1500 to 1800 MPa Structural and Energy Absorbing Components to <2T Bend Radii
Authors: Cola Gary M.
Published: March 2024

Flash Bainite Processing employs rapid thermal cycling (<10s) to strengthen commercial off the shelf (COTS) steel sheet, plate, and tubing into advanced high strength steel (AHSS). In a continuous process, induction technology heats a narrow segment of the steel cross section in just seconds to atypically high temperatures (1000-1300°C). Quenching substantially immediately follows. Flash Processing optimizes the inherent heterogeneity of steelmaking to form a complex intra-granular multi-chemistry, mixture of bainite, martensite, and other morphologies. Carbon migration and carbide dissolution are controlled by limiting time in the austenitic range. Unlike conventional heat treating, homogeneity is intentionally avoided. Flashing steel such as AISI1010 (1100MPa UTS), AISI1020 (1500MPa UTS), AISI1330 (1800MPa UTS), and 13Cr (1800MPa) has shown excellent room temperature stampability. Flash 1500 has room temp stamped into complex shapes including B-pillars and automotive seat components. Flash 1800 has shown <2T bends in complex geometry from 1 to 2mm thick 400x2000mm sheets.
Deformation and Adherence of Fe40Al Particles in Cold Gas Spraying
Authors: Cinca N. , List A. , Gärtner F. , Fernández J. , Guilemany J.M. , Klassen T.
Published: March 2024

This study investigates the impact behavior and consequences for coating formation in cold spraying of FeAl intermetallic compound powder. A range of spraying conditions was used to process single impacts in so-called wipe tests and for processing spray layers. In order to avoid brittle failure, high process gas temperatures and varied traverse speeds were used to account for thermal softening of spray particles and already adhering layers. Morphologies of as-impacted particles and partially removed single splats were subsequently investigated by SEM. The study of spray lines indicates that secondary impacts are only successful within an extremely narrow range of impact conditions. Within this narrow parameter regime, thicker and dense coatings are obtained. Hardness testing shows that the properties of the powders were retained.

Published: March 2024

In this study, twin wire arc spraying is used to deposit dense Inconel skins on 40 PPI nickel foam sheets. A design-of-experiments approach is used to investigate the effects of grit blasting on the surface characteristics of paste-filled foam. In-flight behavior of molten droplets and its effect on coating properties is assessed at three spray distances. The Inconel coatings are evaluated based on SEM and EDS analysis, roughness measurements, and adhesion testing. The results indicate that acceptable adhesion, porosity, and oxide content can be achieved over a small range of grit blasting parameters.
Electro-Catalytically Active Porous Nickel-Based Electrode Coatings Formed by Atmospheric and by Suspension Plasma Spraying
Authors: Aghasibeig M. , Mousavi M. , Ben Ettouill F. , Wuthrich R. , Dolatabadi A. , Moreau C.
Published: March 2024

In this study, atmospheric and suspension plasma spraying are used to create nickel-based electrodes with enhanced surface area as required for hydrogen production. Optimal spraying conditions were determined using a Taguchi design-of-experiments approach. Electrochemical double-layer capacitance measurements by cyclic voltammetry show that suspension plasma spray coatings have more surface area than coatings produced by atmospheric plasma spraying. SEM micrographs show that the surface microstructure of the sample with the largest surface area contains high amounts of cauliflower-like aggregates with an average diameter of 10 µm. In general, the combination of melted, semi-melted, and resolidified particles leads to the formation of deposits with high porosity, rougher surfaces, and consequently larger surface areas.

Published: March 2024

The aim of this study is to determine what types of spray coated metals are desirable for inhibiting iron dissolution in marine environments as a countermeasure against biofilm formation. Experiments were conducted in a closed-loop system in which water continually circulates from a basal water tank through a transparent column where test specimens are immersed. The water flows through an open-air channel on its return to the tank where it is exposed to ambient bacteria. Steel and stainless steel substrates were prepared by plasma and HVOF spraying and, in some cases, a silicon-based sealant was applied. Test specimens were placed in the biofilm reactor and taken out and examined after 5 to 10 days. Substrate surfaces and corrosion products were analyzed by optical microscopy, x-ray diffraction, 3D surface profiling, and low-pressure SEM. Detailed results are presented and discussed in the paper.

Navigating the Intersection
Authors: Mitchell Claudia , Smith Ann
Published: March 2024

In the evolving discourse of contemporary feminism, a critical intersection at the nexus of girlhood studies and the experiences of refugee and displaced girls is evident. We are witnessing unprecedented levels of such displacement because of conflict and climate change among other causes of instability, and this brings the challenges and the triumphs of girls on the move into sharp focus in feminist advocacy and scholarship. This Special Issue, Girls on the Move: Girlhood and Forced Displacement, Migration, and (Re)settlement, guest edited by Rosemary Carleton and Nesa Bandarchian Rashti explores some of the intricacies of this intersection and the articles as a whole advocate for a nuanced feminist response centered on the rights, needs, and voices of refugee and displaced girls.
Girls on the Move
Authors: Carlton Rosemary R. , Rashti Nesa Bandarchian
Published: March 2024

As we write these words to introduce this Special Issue, scores of girls and young women around the world are facing a myriad of challenges as they are forced to flee their homes, leaving behind friends, family, communities, and being propelled into uncertain and very often precarious migratory journeys. Without a doubt, we live in deeply troubling times. While numbers provide a mere glimpse into the devastating humanitarian crisis of forced displacement, they are shocking. Forced displacement, migration, and (re)settlement following conflict, violence, human rights violations, persecution, disasters, and the impacts of climate change, both in nations and across borders, is an ever-escalating crisis affecting tens of millions of people worldwide. Acknowledging that these numbers are unprecedented, the United Nations High Commissioner for Refugees (2023a) reported that by the end of June 2023, over 110 million people were forcibly displaced worldwide and projected that this number would increase to 130 million by the end of 2024. This projected increase takes into account the mass displacement caused by the war between Israel and Hamas as well as ongoing and escalating conflicts in Sudan, Ukraine, and Afghanistan. While current headlines focus principally on the continuing crises in the Middle East and Ukraine, we cannot lose sight of the millions of forcibly displaced persons elsewhere in the world, including those in Eritrea, the Democratic Republic of the Congo, Somalia, Syria, Türkiye, Myanmar, India, Venezuela, and Haiti. Recognizing regional diversity in the staggering numbers serves to underscore forced displacement as a transnational issue that requires urgent global attention.
Wartime, Flight, and Resettlement Realities of Unaccompanied Eritrean Girls in Israel
Authors: Fennig Maya , Denov Myriam
Published: March 2024

We conducted a qualitative study among Eritrean refugees residing in Israel to explore the impact of armed conflict and displacement on adolescent girls’ transition to adulthood. We conducted 19 interviews with young Eritrean refugee women who, as girls and young women, escaped conflict-affected Eritrea and made their way on foot, through Sudan, the Sinai desert, and Egypt to Israel. Our findings reveal how structural and symbolic violence shaped the gendered realities of these Eritrean girls throughout their migration journey. In Israel, while such violence in the forms of precarious immigration status and intimate partner violence were embedded in their everyday lives, participants also drew actively on creative strategies to resist and contest violence.
Protecting Elections: The Case of Kenya
Authors: Kamindo Catherine M.
Published: March 2024

Electoral integrity in Kenya has historically been shaped by constitutional amendments, political intrigues between politicians and political parties, and a culture of disputed presidential election results. This case study examines how reforms of the electoral, legal and institutional framework in Kenya and constitutional amendments in 2010 have influenced electoral integrity in subsequent electoral cycles. Strategies to prevent electoral risks, withstand threats, and recover from crises are presented with case examples. The role of the Independent Electoral and Boundaries Commission (IEBC) and the judiciary in the protection of elections is discussed. The lessons learned from this case study demonstrate that the protection of electoral integrity in Kenya is complex and dynamic, and requires a multi-faceted approach.
Effect of Endothelin Dual Receptor Antagonist on VEGF Levels in Streptozotocin-Induced Diabetic Rat Retina

Published: March 2024

Diabetic retinopathy (DR), one of the most serious causes of blindness, is often associated with the upregulation of vascular endothelial growth factor (VEGF) in retina. Recently, leukocyte adhesion (leukostasis) is blamed for the occlusion of retinal capillary vascularity, which ultimately contributes to the progression of diabetic retinopathy. In addition, intercellular adhesion molecule-1 (ICAM-1), a representative factor for leukostasis, is increased in the diabetic retina. Endothelin (ET)-1, a potent vasoconstrictor peptide, is deeply linked to the pathogenesis of diabetic retinopathy. Different therapeutic interventions concerning VEGF have already been proposed to prevent diabetic retinopathy. However, no study yet has reported whether ET-1 dual receptor antagonist could alter the upregulated VEGF and ICAM-1 levels in the diabetic retina. The present study investigated the effect of ETA/B dual receptor antagonist (SB209670; 1 mg/rat/day) on the expression of VEGF and ICAM-1 in the diabetic rat retina. Diabetes was induced by intraperitoneal injection of streptozotocin (STZ; 65 mg/kg) in Sprague-Dawley rats, whereas control rats (non-DM control) received only citrate buffer. After 1 week, the STZ-administered rats were randomly divided into two groups: one group (DM+SB209670) received ETA/B dual receptor antagonist for 2 weeks, and a vehicle group (DM+vehicle) was treated only with saline. After the treatment period, the retinas were removed from the eyeballs. In DM+vehicle group, the VEGF expression of the retinas was significantly increased (32.8 pg/mg) in comparison to that in the non-DM control group (26.2 pg/mg); this upregulation of VEGF was reversed in the DM+SB209670 group (28.6 pg/mg). The expression of retinal ICAM-1 was increased in the DM+vehicle group (152.2 pg/mg) compared with the non-DM control group (121.6 pg/mg). However, SB209670 treatment did not alter the expression of retinal ICAM-1 level (154.8 pg/ml) in DM rats. Thus we conclude that an ETA/B dual receptor antagonist could reverse the expression level of VEGF in the diabetic retina while failing to normalize the upregulated ICAM-1 expression.

Authors: Berezkin А. , Vivchar R. , Kirichek R.
Published: March 2024

Currently, there is an active growth in the use of unmanned systems in various spheres of activity. The qualitative fulfillment by unmanned systems of their target tasks depends on the efficiency of information exchange channels for their control, which consists of several criteria, which makes the problem of its evaluation a multi-criteria one. This article presents the corresponding evaluation methodology, which is based on the use of the probability of achieving a set of functioning goals as a generalized efficiency indicator. To determine the probability, the widely used Rosenblatt-Parzen nuclear estimation method is used. The main stages of the methodology are described and recommendations for its use in the framework of ensuring qualitative fulfillment by unmanned systems of their target tasks are offered.

Authors: Pitrin A. , Popov A. , Terechenko S.
Published: March 2024

This article proposes the calculation of the probabilities of incoherent reception of signals with binary relative phase manipulation (OFM–2) in the presence of several harmonic interference. Examples of calculating the error probability per bit of receiving signals from OFM – 2 according to the presented method in the presence of several harmonic interference are shown. The obtained graphs depend on the magnitude of the signal at different values of interference and the same magnitude of the frequency shift, as well as on the frequency shift of interference at different levels of signals and interference. The results of the study using this technique allow us to calculate with high accuracy and reliable forecasting the reliability of transmitted information in radio communication channels under the influence of several harmonic interference during processing on two clock cycles. And also to predict the maximum damage to the process of transmitting information in a radio communication channel under various conditions: the coincidence of interference frequencies with the signal frequency, the offset of interference frequencies relative to the signal frequency and the spread of interference frequencies with the signal frequency.

Investigating the Shared Genetic Etiology Between Parkinson’s Disease and Depression
Authors: Reyes-Pérez Paula , García-Marín Luis M. , Aman Asma M. , Antar Tarek , Flores-Ocampo Victor , Mitchell Brittany L. , Medina-Rivera Alejandra , Rentería Miguel E.
Published: March 2024

Background:

Depression is a common symptom in Parkinson’s disease (PD), resulting from underlying neuropathological processes and psychological factors. However, the extent to which shared genetic risk factors contribute to the relationship between depression and PD is poorly understood.

Objective:

To examine the effects of common genetic variants influencing the etiology of PD and depression risk at the genome-wide and local genomic regional level.

Methods:

We comprehensively investigated the genetic relationship between PD and depression using genome-wide association studies data. First, we estimated the genetic correlation at the genome-wide level using linkage-disequilibrium score regression, followed by local genetic correlation analysis using the GWAS-pairwise method and functional annotation to identify genes that may jointly influence the risk for both traits. Also, we performed Latent Causal Variable, Latent Heritable Confounder Mendelian Randomization, and traditional Mendelian Randomization analyses to investigate the potential causal relationship.

Results:

Although the genetic correlation between PD and depression was not statistically significant at the genome-wide level, GWAS-pairwise analyses identified 16 genomic segments associated with PD and depression, implicating nine genes. Further analyses revealed distinct patterns within individual genes, suggesting an intricate pattern. These genes involve various biological processes, including neurotransmitter regulation, senescence, and nucleo-cytoplasmic transport mechanisms. We did not observe genetic evidence of causality between PD and depression.

Conclusions:

Our findings did not support a genome-wide genetic correlation or a causal association between both conditions. However, we identified genomic segments but identified genomic segments linked to distinct biological pathways influencing their etiology.Further research is needed to understand their functional consequences.
The Prevalence of Parkinson’s Disease in Poland: Regional and Sex-Related Differences
Authors: Śmiłowska Katarzyna , Pietrzykowski Tomasz , Owczarek Aleksander J. , Dorsey E. Ray , Bloem Bastiaan R. , van Wamelen Daniel J.
Published: March 2024

Background:

Given the growing evidence for an environmental contribution to the etiology of Parkinson’s disease (PD), searching for local and regional differences in PD prevalence in multiple areas across the world may further clarify the role of environmental toxins.

Objective:

To provide local and regional prevalence estimates of PD in Poland.

Methods:

We analyzed the prevalence of PD and its trend over the last decade (2010 to 2019) based on data from the National Health Fund in Poland. We specifically examined sex differences in PD prevalence, as well as differences across Polish regions.

Results:

During the above period, the prevalence of PD in Poland increased from 226 per 100,000 to 269 per 100,000 inhabitants. Unexpectedly, we found that PD was 1.2-times more common in women than men. The increase in prevalence over the past decade was different between both sexes: an increase from 250 to 283 per 100,000 for women (13.3% increase), and from 200 to 254 per 100,000 for men (27.1% increase). In addition, we observed differences in prevalence across different Polish regions, with some regions having up to 51% lower prevalence rates than others.

Conclusions:

The prevalence of PD in Poland is in line with previously reported prevalence rates across Europe. However, unlike the situation in most of the world, PD was more prevalent in women than men. We discuss several possible explanations as well as potential measures that might help to reduce the growth of PD.
A quality improvement strategy to reduce unintended extubation in the very low birth weight infant: A case report
Authors: Chahin N. , Yitayew M.S. , Shaver L. , Reed J.L. , Ridore M. , Santoro J. , Moores R.R. , Soghier L. , Short B. , Hendricks-Muñoz K.D.
Published: March 2024

BACKGROUND:

Unintended extubations remain a common complication across neonatal intensive care units, with very low birthweight infants being the most vulnerable of them all. Ongoing efforts across different institutions exist with the goal of reducing the rate of unintended extubations to keep a median rate of <2 events per 100 ventilator days as defined by the Vermont Oxford Network. Our objective was to reduce unintended extubations in the very low birthweight infant in a large delivery hospital to ≤2/100 ventilator days.

METHODS:

A collaborative group was formed between two academic health institutions targeting training and implementation of the Children’s National unintended extubation system, focusing on endotracheal tube securement methods and surveillance protocols.

RESULTS:

The unintended extubation rate decreased from 3.23 to 0.64 per 100 ventilator days. Changes were implemented from 2018–2020 with a sustained reduction in the unintended extubation rate of 1.54 per 100 ventilator days. Most events occurred between 12 : 00 pm –4 : 00 pm and the commonest cause was spontaneous (25%) followed by dislodgment during repositioning (19%).

CONCLUSION:

Very low birth weight infants present a challenge to endotracheal tube maintenance due to their developmental and anatomical changes during their neonatal intensive care unit stay. Successful reduction of unintended extubations in the very low birthweight infant can be achieved by adaptation of successful protocols for older infants.
Determination of internal efforts in the base finite elements of SAFEM
Authors: Solodei Ivan , Stryhun Ruslan , Shovkivska Viktoriia , Myronchenko Anastasiia
Published: March 2024

The principles of calculating the internal efforts of a circular finite element in the semi-analytical finite element method (FEM) based on the obtained components of the stress tensor and the peculiarities of the approach associated with the use of the moment scheme of the finite element (FEM) are considered. Formulas for determining longitudinal, shear forces, bending and torque moments have been obtained.
A special place, among the variety of objects considered with the help of analytical and numerical methods, is occupied by bodies of revolution of complex shape and cross-sectional structure, formed by the movement of some creative surface along a closed or opened line without breaks. The selected geometric class is used as natural structures of nodes and details in construction of mechanical engineering. The sufficiently wide distribution of the specified forms in the construction and machine-building industries, on the one hand, and the possibility of significantly simplifying the solving relationships by taking into account their geometric features, on the other hand, provide a basis for the development and use of various modifications of the finite element method (FEM). The semi-analytical finite element method (SAFEM) is one such approach that has gained widespread use for solving problems whose objects are prismatic bodies and bodies of revolution of complex shape and cross-sectional structure. Due to the introduction of additional hypotheses that do not reduce the accuracy of the approximation, the representation of deformations and stresses in physical terms and in accordance with the moment scheme of the finite element (MSFE), on the one hand, it is possible to avoid the time-consuming procedure of numerical integration over the cross-sectional area of the finite element (FE), on the other hand - maintain the high efficiency of 3D discretization.
Despite the large number of publications devoted to the semi-analytical method of finite elements, the question of determining internal forces, which are often component factors of the strength criteria laid down in state building codes, is inappropriately neglected. The use of SAFEM in combination with МSFЕ creates some mathematical features of calculating internal longitudinal, shearing forces and moments.

Published: March 2024

The article presents a method for solving the problem of eliminating vibrations of the load, which is fixed on a rigid articulated suspension at the time of simultaneous movement of two links of the boom system. The essence of the method is to optimize the mode of simultaneous movement of two links of the boom system of the loader crane with horizontal movement of the load during the start-up period. The problem is solved according to two optimization criteria, namely: according to the optimization criterion of the root-mean-square value of the generalized force and the optimization criterion of the root-mean-square value of the power of drive mechanisms. The developed criteria reflect the undesirable properties of the links of the boom system and drive mechanisms, so their value was minimized.

The solution of the optimization problem is presented in a discrete form. For this purpose, the particle swarm optimization (ME-PSO) method was used. This helped to obtain discrete values of the kinematic and power characteristics of the boom system of the loader crane.

Since the optimization criterion is an integral functional, the methods of the calculus of variations are used for its optimization. The solution of the variational optimization problem is presented in the form of many parametric functions that satisfy the boundary conditions of motion and minimize the obtained dimensionless criteria. For this purpose, the particle swarm optimization (ME-PSO) method was used. This made it possible to obtain the dependence of the optimal energy and power characteristics of the boom system and the drive mechanisms of the loader crane. The mode of movement of the boom system links obtained as a result of optimization improved the power and energy characteristics of the loader crane, which made it possible to increase its reliability and productivity.

The article substantiates the relevance of the design and construction of buildings and structures of the Ukraine population civil protection in the conditions of possible shock-explosive influences. The aim of the work is to systematize information about the impact of explosive loads on building structures and develop recommendations for improving the stability of buildings and civil protection structures.The influence of shock wave during the detonation of explosives on the structures of buildings is considered and systematized. The features of distribution of pressure of blast wave on the structures of buildings in time, depending on magnitude of their distances to the epicenter of the explosion, are analyzed. The features of the influence of blast wave, which expands from the source of detonation, on low-rise buildings with flat roofs and the sequence of development of deformations and destruction of their structures at three stages of wave propagation are revealed. The nature of the influence of blast wave on multi-storey and high-rise buildings and the sequence of development of deformations and destruction of their structures are analyzed. Examples of destruction of structures of buildings of various structural systems from explosions are given.The paper gives recommendations for design of blast-resistant buildings with built-in bomb shelters that are able to resist explosive loads without progressive collapse, which leads to a cascading sequence of damage to adjacent building structures. The ways of redistribution of gravitational loads on the structural systems of buildings and structures are analyzed, recommendations are made for design of explosion-proof buildings.Conclusions are drawn about the feasibility of using monolithic reinforced concrete frames, which are able to plastically deform, redistribute loads and resist the onset of progressive collapse, which leads to appearance of a cascading sequence of damage to adjacent building structures.

The issue of modeling geometrical imperfections in the dynamics problems of thin-walled shells was little researched. In cases when the natural modes of shell coincided with its buckling modes, the issue of choosing a dangerous imperfection model did not arise. When these shell modes did not coincide, it was important to investigate and compare the effect of different imperfections models on the static and dynamic characteristics of such shells. The choosing the shape imperfections model of a long flexible cylindrical shell subjected to force couples, the natural and buckling modes of which did not coincide, was studied using procedures of the finite element analysis software NASTRAN. The shell wall as a set of plat rectangular elements with six degrees of freedom at the node in the cylindrical coordinate system was modeled. The action of force couples as the concentrated forces were distributed at the nodes of the shell edges in accordance to the presentation of A.S. Volmir. The linear buckling problem and the geometrical nonlinear static analysis of the perfect shell by the Lanzosh method and the Newton-Raphson one were performed, respectively. The long half-waves buckling mode was taken as the first shell imperfections model. The modeling of the second shape imperfections as the first natural mode of the perfect shell using the natural vibration analysis by the Lanzosh method was performed. The different amplitudes of geometrical imperfections in proportion to the shell thickness using a program adapted to this software were set. The results of the geometrical nonlinear static analysis of the imperfect shell by the Newton-Raphson method showed that the shape imperfection model in the form of long half-waves more reduced the values of critical buckling loads. Investigations of natural shell vibrations by the Lanzosh method revealed the same influence of different imperfections models on the natural frequencies and natural forms. We think that the shape imperfections model in the form of long half-waves in studies of forced vibrations and dynamic stability of a long flexible cylindrical shell subjected to force couples will be more effective.
Assessing Reliability and Economic Viability of Different EV Charging Station Configurations

Published: March 2024

With the increasing popularity of electric vehicles (EVs) as a mode of transportation, companies are prioritizing the development of charging infrastructure to cater to customer needs. Despite efforts to align charging station designs with distribution system requirements, maintaining reliability for EV charging ports remains challenging. To enhance reliability, a novel 56-ported design incorporating both uniform and non-uniform port arrangements has been proposed. These configurations have been tested with distribution systems ranging from 50 to 500 kW. Reliability assessments were conducted using standards outlined failure rate estimation and monte-carlo functions for evaluating port probability functions in terms of failure rate and reliability. By analyzing the failure rates of individual ports, an evaluation process was introduced to determine the overall success rate of the charging station. The failure rate of the proposed 56-ported charging station was further evaluated using the binomial distribution method. Additionally, cost estimation procedures were implemented considering the failure and success rates of individual port maintenance for the proposed configuration. The findings indicate that achieving lower failure rates and maintenance costs is possible through improved port arrangement reliability and enhanced voltage stability.
Quantum Theory of Soul

Published: March 2024

The pursuit of scientific research on the soul has garnered increasing attention, yet progress has been limited. We propose that to scientifically study the soul, one must first provide it with a precise scientific definition. In this paper, we delve into the process of defining the soul scientifically and employing quantum physics to study and predict its character, qualities, and behavior.

Building upon our previous work, which presented a novel interpretation of quantum physics suggesting that everything at its core is a quantum vibrational field carrying information, energy, and matter, we put forward the concept that the soul is the content of the information carried in one’s quantum vibrational field. With this definition in mind, and drawing upon the principles of quantum physics, we outline seven predictions about the soul:

1. SOUL AS ESSENCE: The soul is posited as the essence of one’s existence, determining every aspect of life.
2. CONTINUITY OF SOUL: The soul may persist on its journey beyond the cessation of the physical body.
3. ETERNAL NATURE: Despite the limitations of the physical body, the soul can be eternal and boundless.
4. REMOTE INTERACTION: Individuals can connect with, communicate with, and influence other souls remotely.
5. EXISTENCE OF AKASHIC RECORDS: A universal quantum vibrational field, known as the Akashic Records, contains information, energy, and matter about everything.
6. EXPLANATION OF SPIRITUAL ABILITIES: Spiritual abilities like intuition, telepathy, and psychokinesis can be scientifically elucidated.
7. PURPOSE AND MEANING: The soul imbues life with purpose and meaning.

These predictions align with widespread spiritual wisdom and offer the potential for experimental verification.

Our quantum theory of soul aligns with monism, positing that the soul, spiritual heart, mind, energy, and matter are all interconnected aspects of a unified existence—the quantum vibrational field. It also supports panpsychism, suggesting that everything possesses varying degrees of soul, consciousness, and other attributes. This framework expands scientific inquiry beyond physical matter and energy to encompass soul, consciousness, and spiritual phenomena. Importantly, it bridges the gap between science and spirituality at a fundamental level, aligning with both spiritual wisdom and the discoveries of quantum physics.
