A comparative inference on reliability estimation for a multi-component stress-strength model under power Lomax distribution with applications
Authors: Ahmad Hanan Haj , Almetwally Ehab M. , Ramadan Dina A.
Published: August 2022

In this article, reliability estimation for a system of multi-component stress-strength model is considered. Working under progressively censored samples is of great advantage over complete and usual censoring samples, therefore Type-II right progressive censored sample is selected. The lifetime of the components and the stress and strength components are following the power Lomax distribution. Consequently, the problem of point and interval estimation has been studied from different points of view. The maximum likelihood estimate and the maximum product spacing of reliability are evaluated. Also approximate confidence intervals are constructed using the Fisher information matrix. For the traditional methods, bootstrap confidence intervals are calculated. Bayesian estimation is obtained under the squared error and linear-exponential loss functions, where the numerical techniques such as Newton-Raphson and the Markov Chain Monte Carlo algorithm are implemented. For dependability, the largest posterior density credible intervals are generated. Simulations are used to compare the results of the proposed estimation methods, where it shows that the Bayesian estimation method of the reliability function is significantly better than the other methods. Finally, a real data of the water capacity of the Shasta reservoir is examined for illustration.

Authors: Bakić Damjan , Gligorijević Vera
Published: August 2022

This paper explores marital matching patterns from the perspective of the partners' educational attainment, focusing on the link between gender asymmetry in education and educational hypergamy. In order to assess to what extent the tendency for women to marry men of higher educational status is related to the educational gender gap in Serbia and Slovenia, we calculate an index for women's educational advantage, and an index for the prevalence of educational hypergamy. Our results confirm the following: the growth of education is associated with an increase in female educational advantage; the relationship between female educational advantage and educational hypergamy is strongly negative; and there are no significant differences in assortative mating patterns between Serbia and Slovenia.
Home, Family, and War: Images of Home in the Ukrainian Novel About the War in Donbass
Authors: Jakubowska Krawczyk Katarzyna , Zambrzycka Marta
Published: August 2022

This article focuses on one of the most pressing issues in Ukraine today, the ongoing war in the Donbass. Using selected examples of Ukrainian prose, the authors analyse the impact of the war on the fate of individuals and their families. However, the theme goes far beyond the literary text and touches on important social and political issues facing Ukraine today. The authors understand prose as one of the narratives of culture, which not only conceptualizes reality in a certain way, but also has a real impact on social attitudes. Contemporary Ukrainian prose about the war in the Donbass analyses many stereotypes about the inhabitants of eastern Ukraine, shows them in their complicated family relationships, and also takes up one of the most universal literary motifs, namely the figure of the house in the face of a disruption of its everyday order. Characteristic of this prose is the individualized perspective, which aims not only to present events on a broad political level, but above all to draw attention to the impact of these events on the individual. Such an individualized perspective is an effective means of reaching the recipient and making him aware of the multidimensionality of the military conflict taking place before our eyes.
Glas praznika v nevihtnem času: Heideggerjeva vojna predavanja o Hölderlinu
Authors: Gudović Milosav
Published: August 2022

Članek obravnava tematiko vojne skoz prizmo izbranih odlomkov Heideggerjevih tolmačenj poezije. Osrednji del razprave je posvečen delu Razjasnjenja ob Hölderlinovem pesništvu in predavanjem o himni »Spomin« (»Andenken«). Hermenevtično soočanje s Hölderlinom sredi viharja druge svetovne vojne ni bilo estetski beg pred okrutno resničnostjo. V knjigi Zgodovina Bitja (Die Geschichte des Seyns) Heidegger poudarja pojem »totalne vojne« kot splošnega, zunanjega razdiranja. Nasprotje tej tendenci lahko prepoznamo v Hölderlinovem motivu »krilate vojne«. V interpretaciji, ki jo tu predlagam, je »krilata vojna« pesniško ime človekovega notranjega premagovanja slabih nagonov in dolgo gibanje navzgor – od sovražnega srda do odprtosti in prisrčnosti. V luči takšnega branja se vojna kaže kot »nevihtno« obdobje, ko pozaba tega najvišjega podviga duše doseže svoj vrhunec. Heideggerjevo »pesniško mišljenje« in Hölderlinova miselno bogata poezija utirata skupno pot od praznine totalne vojne do praznika kot simbola popolne sprave in osmislitve časa.

Authors: Myachina Maria , Gavrilova Natalia , Nazarov Victor
Published: August 2022

Dispersions of molybdenum-tungsten blues are promising precursors for the preparation of carbide catalysts by the sol-gel method. Stable systems were synthesized using ascorbic acid as a reducing agent at various molar ratios (Mo) :( W) = 100; 95: 5; 90:10; 80:20; 50:50. To study the properties of colloidal systems, UV / Vis spectroscopy, dynamic light scattering and electrophoretic light scattering were used. It was found that molybdenum-tungsten blue particles with different molar ratios of molybdenum and tungsten have a constant hydrodynamic radius equal to 2.0 nm. In the pH range (0.8 - 3.0) molybdenum-tungsten blue particles are negatively charged; the absolute values of the ζ-potential do not exceed 25 mV.

The synthesis of acid-activated Al2O3-pillared bentonite as a solid acid catalyst has been completed. The pillarization process was carried out using the varying pf calcination time, mole OH/Al ratio, and mmol of Keggin/bentonite to determine the optimum total acidity. The higher the calcination time, (OH/Al) ratio, and suspension concentration, the greater the acidity of ​​the Al2O3-pillared bentonite. The optimum conditions were achieved at a calcination time of 20 minutes, a mol of (OH/Al) ratio of 2.2, and Keggin/bentonite of 10 mmol with a total acidity of 11.76 mmol gram ammonia and 2.44 mmol/gram pyridine. The pillared bentonite had a surface area of ​​154.64 m2/g and a pore diameter of 3.38 nm. The pillaring process was successfully increasing the basal spacing of natural bentonite from 14.77 to 17.78.

Authors: Putri Ulfa Rahmawati , Siswanta Dwi , Hermawan Dadan , Mudasir Mudasir
Published: August 2022

A study of the molecular anchoring and inclusion complex of the R/S-ibuprofen chiral compound with α-1-acid glycoprotein (AGP) has been carried out. This study aimed to predict the chiral separation of ibuprofen using chiral column filled with AGP protein. The geometrical optimization of R/S-ibuprofen was conducted on different calculation methods to obtain the optimal molecular structure. Molecular docking approaches, specifically docking using AutodockTools software were used to predict R/S-ibuprofen separation in AGP chiral column by comparing the binding energy values and the type of interaction. Results of the study show that the best method for optimizing the geometry of ibuprofen is Density Functional Theory (DFT). Furthermore, the results of the specific anchoring of ibuprofen on the AGP shows that the binding energy of S-ibuprofen with AGP is more negative than that of R-ibuprofen, namely -5.63 and -5.55 kcal/mol, respectively, indicating that S-ibuprofen interacts more strongly with AGP and therefore it will be eluted from the AGP chiral column later after R-ibuprofen.

Authors: Sabdowati Rosati , Siswanta Dwi , Hermawan Dadan , Mudasir Mudasir
Published: August 2022

Prediction of chiral separation of R- and S-ketorolac has been carried out using a molecular docking approach. Geometry optimization using different calculation methods suggests that Hartree-Fock (HF)/6-31G is the best method to describe the most stable ketorolac structure. Docking studies have been performed on AutoDock and Gaussian software. Molecular docking results were used to predict the separation of ketorolac enantiomers in the AGP (alpha-1-acid-glycoprotein) chiral column by comparing the binding energies and types of interaction. To ensure the accuracy of the results, not only specific docking was performed, but blind docking was also conducted in this study. The results of the study show that the binding energy of S-ketorolac is more negative than that of R-ketorolac, indicating that stronger interaction between S-ketorolac and AGP occurs. Therefore, the R-ketorolac will be eluted first from the AGP column followed by S-ketorolac. As expected, this prediction is in good agreement with the experimental results of the separation of ketorolac enantiomers.

Because Sri Lanka have already proved that the best place to obtain a superior experience. According to the current situation in tourism sector has been influences by this pandemic and post situation highly. Parties in the tourism sector are facing several difficulties to aligned with this new normal situation. At the same time, countries that are gaining several competitive advantages from the tourism sector have adopted the wellness tourism concept especially other Asian countries namely, India. Because it is a timely concept to win this modern business era, this study explored to provide a critical evaluation of literature on the wellness tourism and the possibility of appalling this concept into the Sri Lankan context. A rigorous literature review is carried out by choosing conceptual and empirical papers mostly published after 2015 in reputed journals to evaluate the wellness tourism concept discussed by many authors critically. The findings of this study provide valuable insight into the stakeholders in the Sri Lankan tourism sector to implement this concept successfully. Currently Sri Lankan Tourism sector expands in Down-South, Central and Eastern provinces but less into wellness tourism application. Thus, these insights may valid forward to implement wellness tourism in above domains as an alternation for the current tourism intensity. Manly, government authorities, owners, and managers of the tourism sector should engage with digital technologies when providing their service package. Further, wellness tourism cities should consider the main three pillars, namely human capital, infrastructure, and information. Not only that but also community collaboration is another critical factor that should pay attention. Further, within this study developed a model that represents the connection between several components of a smart tourism city.

Published: August 2022

Customers may switch to a different service provider if they are displeased with the standard, hence tracking service quality is crucial for a firm. The influence of Internet Service Quality (ISQ) on Customer Satisfaction will be studied in detail by the researcher. The relevance of this study is highlighted by the current COVID-19 scenario in Sri Lanka, where government laws and restrictions have been implemented to promote work from home, online learning, and online entertainment. Previous research in other countries have looked at the impact of ISQ on customer satisfaction; however, to our knowledge, no such study has been conducted in Sri Lanka. Furthermore, earlier study looked at a variety of scenarios, including the discovery of research gaps; however, in the context of COVID-19, the research gaps were identified. Past research identifies the following factors which impact ISQ: Tangibility, Assurance, Empathy, Reliability, Responsiveness and Price. This study was carried out as a deductive study and a quantitative method was employed. The convenience sample approach was used to collect 505 responses by distributing a questionnaire survey to consumers in Sri Lanka's Western region. Statistical Package for Social Science (SPSS) version 23 was used to analyze the data. The studies indicated that Internet Service Quality and Customer Satisfaction had a favorable association. The study was also able to provide insights for ISP management by emphasizing areas of ISQ that can satisfy their customer base, as well as actions that might be implemented in response to the observed practice gaps.

Published: August 2022

The super market industry in Sri Lanka is highly competitive and a drastic improvement has been observed in the last decade as consumer lifestyle is changing with greater degree of influence by Western lifestyles. Due to heavy competition in the super market industry, super markets are pushed into a situation to focus more towards customer acquisition and retaining programs in order to increase their market share. However, leading super market chains suggest that despite acquisition programs making impact, customers who have been already acquired by the organizations are switching to competitors. Hence, in order to obtain competitive advantage over competitors, super market chains ought to focus executing effective customer retaining program like loyalty program that would have a positive impact on the business performance of the organization. However, presently, super market chains have implemented loyalty programs that don’t yield expected benefits due to drawbacks in the loyalty programs which prevent customers from participating in the loyalty programs due to customer dissatisfaction on loyalty program in general. The research is essentially aimed at identifying factors that have impact on customer satisfaction on customer loyalty program to participate in super market industry. Anticipated Benefits, Privacy concerns, Variety seeking, Customer involvement and commitment are four key factors identified through literature survey that impact on customer participation to loyalty program. The shoppers of Keells, Cargills and Arpico and Laugfs were selected to represent the different loyalty card types in this research and all the Individuals in Colombo district who do their purchases at supermarkets qualify as the population for the research. The results of the study discuss the impact of customer retainment and engagement factors of loyalty card programs on customer satisfaction and the significant impact of those factors on the customer satisfaction.

Authors: Tiwari Aseem Kumar , Luthra Aanchal Sunil , Arora Dinesh , Mehta Swati Pabbi , Aggarwal Geet , Sood Nitin , Yadav Satyaprakash , Upadhyay Anand Prakash
Published: August 2022

BACKGROUND AND OBJECTIVES:

Enumeration of hematopoietic progenitor cell (HPC) is vital to decide the time to initiate harvest (TTIH) and adequacy of harvest dose (AOHD). Standard of care used for HPC enumeration is flowcytometric CD34+ enumeration, but it is expensive, time-consuming and requires skilled staff to perform the test. Alternatively, HPC-count by advanced automated cell analyzer is cheaper, quicker, and easy-to-perform test. Our objective was to find a correlation of HPC count with CD34+ enumeration in leukapheresis.

MATERIALS AND METHODS:

An observational, prospective study was conducted in the year 2018–2019. A total of 126 samples were included in the study, the peripheral blood (PB) group comprised of 42samples and apheresis group of 84 samples. The samples were simultaneously tested for CD34+ expression and complete blood count which included the HPC count, white blood cells (WBC) count and multinational corporation (MNC) count and correlation analysis was performed with CD34+ flowcytometric count. The cut-off of PB HPC count for the target dose of 5 × 106 CD34+ cells/kg was established using Receiver Operator Curve.

RESULTS:

The correlation coefficient (r) of HPC with CD34+ count was 0.617 and 0.699 for PB group and apheresis group sample respectively, which was statistically significant. The correlation with MNC and WBC count was not very significant. A cut-off value of PB HPC was established to be 66 HPC/ml with a positive predictive value of 94.12%. The cost of CD34 + flow cytometric enumeration was six times that of HPC enumeration by analyzer.

CONCLUSION:

The HPC count is a cheaper, rapid and easy test and can be clinically applied to predict TTIH and AOHD but requires more studies to validate its efficacy in clinical use.
“Never Burn Your Bridges” – A Difficult Airway Scenario
Authors: Sharma Juhi , Mittal Tushar
Published: August 2022

Anaesthesia for otorhinolaryngological procedures has always been challenging in view of a shared and often difficult airway. A 55-year-old male, a known case of carcinoma right maxilla, presented to us following right total maxillectomy, bilateral anterior and posterior ethmoidectomy, sphenoidectomy and right supraomohyoid neck dissection. He needed a revision maxillectomy in view of a residual lesion predominantly in the right superior nasal cavity and maxillary sinus. Mouth opening was restricted to 1.5 cm making direct laryngoscopy impossible. The mass in the right nasal cavity had eroded and caused deviation of the nasal septum completely towards the left, making nasal fibrescopy also difficult. We successfully managed the airway using the technique of asleep oral fibreoptic-guided intubation.

Epidemiology of Clostridium (Clostridioides) difficile Infection in Southeast Asia
Authors: Khun Peng An , Riley Thomas V.
Published: August 2022

This review describes the current understanding of Clostridium (Clostridioides) difficile infection (CDI) in southeast Asia regarding the prevalence of CDI, C. difficile detection methods, antimicrobial susceptibility profiles, and the potential significance of a One Health approach to prevention and control. Our initial focus had been the Indochina region, however, due to limited studies/surveillance of CDI in Indochina, other studies in southeast Asian countries and neighboring Chinese provinces are presented here for comparison. Clostridium (Clostridioides) difficile infection is one of the most common causes of hospital-acquired gastroenteritis worldwide. Since its discovery as a cause of pseudomembranous colitis in 1978, C. difficile-related disease has been more prevalent in high-income rather than low-income countries. This may be because of a lack of knowledge and awareness about the significance of C. difficile and CDI, resulting in underreporting of true rates. Moreover, the abuse of antimicrobials and paucity of education regarding appropriate usage remain important driving factors in the evolution of CDI worldwide. The combination of underreporting of true CDI rates, along with continued misuse of antimicrobial agents, poses an alarming threat for regions like Indochina. C. difficile ribotype (RT) 027 has caused outbreaks in North America and European countries, however, C. difficile RT 017 commonly occurs in Asia. Toxin A-negative/toxin B-positive (A−B+) strains of RT 017 have circulated widely and caused outbreaks throughout the world and, in southeast Asia, this strain is endemic.
Case Report: Multiple Scalp Abscesses due to Mycobacterium abscessus Infection Following Triamcinolone Injection in an Immunocompetent Person
Authors: Mohanty Monalisa , Mishra Baijayantimala , Sirka Chandra Sekhar , Mohapatra Prasanta Raghab
Published: August 2022

Mycobacterium abscessus complex is a group of nontuberculous mycobacteria (NTM). The NTM may involve skin, soft tissue, and other organs like the eye and central nervous system. Clinically may mimic multidrug resistance. Here, we present a case of a 29‐year man with a history of multiple scalp swellings with mild symptoms. He had undergone multiple triamcinolone acetonide injections on his scalp to stop hair fall and baldness 2 months prior. As there was a history of injections on the scalp and lesions associated with minimal symptoms, we suspected the possibility of NTM and fungal infections. As a part of treatment and obtaining a sample for investigation, lesions were aspirated with a needle. The swellings contained gelatinous material, which was sent for microscopic examination, and revealed the presence of acid‐fast bacilli (AFB). Xpert MTB/RIF assay was negative for mycobacteria (MTB complex), but culture revealed NTM was identified as M. abscessus complex by line probe assay. Based on the diagnosis, the patient was treated with an injection of amikacin, moxifloxacin, and azithromycin. The lesions improved. The patient has completed over a year of follow-up with no recurrence noted. Mycobacterium abscessus, a rapidly growing NTM, has been occasionally reported to cause cutaneous soft tissue infection when injected with nonsterile medicine or needles. Therefore, a high index of suspicion for NTM infection is warranted in patients with cutaneous scalp abscess following scalp injections for hair loss.
ХУДОЖНЄ ПЕРЕЖИВАННЯ ТРАГЕДІЇ ВІЙНИ (НА ПРИКЛАДІ РОМАНІВ Е.М. РЕМАРКА “ТРИ ТОВАРИШІˮ І ТАМАРИ ГОРІХА ЗЕРНЯ “ДОЦЯˮ)
Authors: Солодка Лілія
Published: August 2022

У статті здійснено компаративний аналіз воєнного дискурсу романів Е. Ремарка “Три товариші” та Тамари Горіха Зерня “Доця”. Розкрито антигуманну сутність війни на прикладі руйнівного впливу на людські долі. Увага зосереджена на порівняльному аналізі художньої реалізації моральної стійкості героїв у протидії деструктивного впливу війни на людську психіку й мораль. З’ясовано, що попри тяжкі випробування, головні герої обох творів зберігають кращі людські якості й залишаються поборниками справедливості. Мотиви дружби, любові, життєстійкості протистоять мотивам зневіри й бажання помсти. Через вчинки героїв розкрито онтологічну та аксіологічну парадигми їхніх доль. Порівняльний аспект українського й німецького творів дозволив простежити вплив війни на людську особистість на початку ХХ і ХХІ ст. Через поняття “втраченого покоління” змодельовано модуси руйнівного впливу війни на людську свідомість. Незважаючи на руйнівні наслідки воєнних катаклізмів, головні персонажі обох романів прагнуть зберегти духовну цілісність. Протидією згубного впливу виступають сімейно-моральні цінності, які суттєво впливають на психологію та емоційний стан героїв, допомагають їм продовжувати рухатися вперед. Відкритий фінал розкриває нові можливості подальшої самореалізації для персонажів та для читачів.

Inicialmente se encontró que los estudiantes presentaban problemas de tolerancia, mediante la aplicación de una encuesta orientada a evaluar varios aspectos de conducta frente a las actitudes de sus compañeros y algunas condiciones del entorno, y la revisión del informe de convivencia y disciplina que realiza la institución periódicamente. En función de los resultados del diagnóstico, se diseñó y desarrolló en 24 sesiones un programa lúdico-deportivo de ultimate frisbee, basado en la práctica de sus fundamentos técnicos y principios de juego básicos. La objetividad del programa para la promoción de valores como la tolerancia, y la fiabilidad de la encuesta como instrumento para medir la tolerancia fueron avalados por expertos. Después se aplicó nuevamente la encuesta y se revisó el informe de convivencia, para valorar los efectos del programa, encontrándose que la mayoría de faltas relacionadas con la intolerancia disminuyeron significativamente. En conclusión, se fortaleció la tolerancia con los estudiantes a partir de la vivencia del programa, fundamentalmente en aspectos como la disminución de agresiones entre compañeros y el establecimiento de respuestas asertivas a las mismas, y un comportamiento más tolerante durante las clases de Educación Física.

Vehicular Adhoc Network (VANET) is a distinct type of Mobile Adhoc Networks (MANET) that
makes use of moving vehicles as nodes to create a mobile network. The vehicles that are in radio
range of each other can communicate with one another. Timely message dissemination is extremely
important for the delivery of critical information. Generally, data dissemination in VANET is
broadcast oriented. Multihop broadcasting can be used to spread emergency messages. In this paper,
the proposed work is compared with the existing approaches using NS2. The simulation results
show the reduction on transmission delay and improved packet delivery ratio.

TİFLİS’İN FETHİ VE OSMANLI’YA ENTEGRASYON ÇABALARI (1723-1735)
Authors: Çelik Kübra Nur , Tuğluca Murat
Published: August 2022

Osmanlı Devleti Tiflis’i 1723’te fethetmiş ve 1735’e kadar elinde tutmuştur. Bu çalışmada Osmanlı hâkimiyetine girdikten sonra Tiflis’te yapılan düzenlemeler entegrasyon bağlamında incelenmiştir. Bu doğrultuda Tiflis’in fethi ve sonraki süreçte Osmanlı klasik fetih yöntemlerine benzer bazı temel uygulamaların hayata geçirildiğine şahit oluyoruz. Bunlar; tedrici fetih yöntemi, tahrir-tımar, istimalet, iskân ve vakıflarla şenlendirme politikalarıdır. Bu süreci yakından takip etmek üzere Tiflis’in fethinden sonra arşivde tutulan defterlerle belgeler incelenmiştir. İlk olarak gerçekleştirilen askeri, idari, lojistik ve imar faaliyetlerine göz atılmıştır. Böylelikle Tiflis’i ve hinterlandını elde tutmak ve askeri gücü artırmak için yapılan düzenlemeler tespit edilmiştir. Bilindiği üzere tahrir ve tımar faaliyetleri Osmanlı entegrasyon sürecinin temeline oturmaktadır. Bu faaliyetlerin Tiflis örneği, klasik fetih modeline uygunluğun en önemli işareti olarak gözlenmiştir. Ardından ahalinin gönlünü kazanmak üzere yapılan faaliyetler istimalet politikası çerçevesinde ele alınmıştır. Buradaki çabaların tam olarak istenen düzeyde gerçekleştiğini söylemek pek mümkün görünmüyor. İskân faaliyetlerinde de istimalet politikasına hizmet edecek türde faaliyetlerin gözetildiği anlaşılmaktadır. Son olarak yeni fethedilen bir bölgenin toplumsal entegrasyonu sağlamada etkin bir şekilde kullanılan vakıfların Tiflis’te de önemli roller üstlendiği söylenebilir. Netice itibariyle bu çalışma ile Tiflis’in 1723’te fetih ve sonrasında gerçekleştirilen faaliyetlerin Osmanlıların erken ve klasik dönem fetih yöntemleriyle ve entegrasyon çabalarıyla uyum içerisinde olduğu görülmüştür.

Tarih süresince milletler tarafından bir varoluş mücadelesi verilmiştir. Bu mücadele örneğinin barış sembolü olarak olimpiyatlar kabul edilmiştir. M.Ö 776 yılından itibaren başlayan olimpiyat müsabakaları M.S 393 yılına kadar devam etmiştir. Uzun bir zamana yayılan unutulmuşluğun ardından çağdaşlaştırılmış bir vaziyette 1896 yılında Atina şehrinde tekrar yapılmıştır. Modern olimpiyatların ortaya çıkmasında etkili olan isim Baron Pierre de Coubertin’dir. Uluslararası Olimpiyat Cemiyeti (IOC) 1894 yılında kurulmuş ve olimpiyatların geliştirilmesine yönelik faaliyetlerde bulunmuştur. Uluslararası Olimpiyat Cemiyeti’nin Osmanlı Devleti ve Türkiye Cumhuriyeti temsilcisi Selim Sırrı Bey olmuştur. Terbiye ve Oyun Mecmuası’nın imtiyaz sahibi ve ser muharriri olan Selim Sırrı Bey olimpiyat oyunlarına özel bir ilgi duymuş ve gerektiğinde de bizzat olimpiyat oyunlarına katılarak gözlemlerini aktarmıştır. Özellikle de 1912 Stockholm Olimpiyat Oyunları’nı yakından takip ederek notlar almıştır. Oyunlardan sonra tüm ayrıntıları Terbiye ve Oyun Mecmuası’nda yayımlamıştır.

At present, the requirements for flying machines, in terms of increasing flight speeds, maneuverability, and flight intensity, significantly expand the range of tasks to be solved by the radio-electric equipment of these machines. Therefore, during their design and construction, problems arise with the placement of a large number of antennas and radio-electronic devices. In addition, for maneuvering and flight dynamics, it is not allowed to place additional protrusions on the devices. From the obtained results, we can assume that the electrodynamic properties of the considered system can be changed by the variation of the system's feeding mode.
