Abstract. Biological soil crusts (biocrusts) composed of cyanobacteria, bacteria, algae, fungi, lichens, and bryophytes stabilize the soil surface. This effect has mainly been studied in arid climates, where biocrusts constitute the main biological agent to stabilize and connect soil aggregates. Besides, biocrusts are an integral part of the soil surface under mediterranean and humid climate conditions, mainly covering open spaces in forests and on denudated lands. They often develop after vegetation disturbances, when their ability to compete with vascular plants increases, acting as pioneer communities and affecting the stability of soil aggregates. To better understand how biocrusts mediate changes in soil aggregate stability under different climate conditions, we analyzed soil aggregate samples taken under biocrust communities from four national parks in Chile along a large climatic gradient ranging from (north to south) arid (Pan de Azúcar), semi-arid (Santa Gracia), mediterranean (La Campana) to humid (Nahuelbuta). Biocrust communities showed a stabilizing effect on the soil aggregates in dry fractions for the three northern and the wet aggregates for the southernmost sites. Here, permanent vascular plants and higher contents of organic carbon and nitrogen in the soil control aggregate stability more than biocrusts, which are in intense competition to higher plant communities. Moreover, we found an increase in stability for edge aggregate size classes (< 2.0 mm and 9.5–30.0 mm). The geometric mean diameter of the soil aggregates showed a clear effect due to the climatic gradient, indicating that the aggregate stability presents a log-normal instead of a normal distribution, with a trend of low change between aggregate size fractions. Based on our results, we assume that biocrusts affect the soil structure in all climates. Their role for aggregate stability is masked under humid conditions by higher vegetation and organic matter contents in the topsoil.
Medical Student Teleconferencing Experiences and Financial Status: A Cross-Sectional Survey

Published: March 2022

Background: Teleconferencing issues may affect the online experiences of medical students during medical education and residency interview evaluation, yet teleconferencing experiences among medical students with varying financial status have not been examined.
Methods: In October of 2020, the authors conducted a cross-sectional single-institution survey of fourth-year UCLA medical students on self-reported financial status, teleconferencing issues experienced, preparations made for online residency interviews, and satisfaction with teleconferencing equipment. Responses of students who self-identified as financially disadvantaged were compared to those of students without financial hardship using Fisher’s exact tests.
Results: Of 268 students, 67 responded (25%), and 27 (40%) of respondents identified as financially disadvantaged. A majority of students reported problems with internet connectivity (75%) and audio quality (51%). Nearly one-third of students (30%) reported plans to improve their internet connectivity for online residency interviews. Of respondents, 58% were satisfied with the quality of their teleconferencing equipment. Students dissatisfied with their equipment were more likely to report audio problems (68% vs. 38%, P = 0.03) and internet connectivity issues (89% vs. 64%, P = 0.01). Financial status was not significantly associated with teleconferencing issues, device age, satisfaction with teleconferencing equipment, or the amount that students would be willing to spend on acquiring new equipment.
Conclusion: Teleconferencing issues, particularly audio and internet problems, are highly prevalent among fourth-year medical students and are associated with dissatisfaction with teleconferencing equipment but not self-reported financial status. The influence of teleconferencing issues on student evaluation outcomes warrants further investigation.
ASPIRE - A Journey from Intuition to Innovation
Authors: Mulkalwar Alhad
Published: March 2022

The idea of academic research is perceived by many students as interesting, but what stops them from actually indulging in it, is a simple question, ‘How does one start?’ Those who do start seldom remain with the project till the end and very few eventually co-author the publication. This attrition could be fuelled by numerous factors including lack of right mentorship, conflict with academics, or simply a loss of interest. There was a need to practice and teach research from the perspective of an undergraduate and hence inculcate the culture of Research and Evidence-Based Medicine into medical education. As a solution to this predicament, a student-led research council named, ‘A.S.P.I.R.E: Association for Support and Propagation of Innovation, Research & Education’ was formed. Its activities were focused on building a peer-based research environment to learn via module-wise teaching and mentoring sessions and a practical approach to inculcate the culture of evidence-based medicine in young professionals via Journal club sessions. This article summarizes the author’s experience of implementing this idea and the hurdles and barriers he faced in the process. The author also provides a reflection on this journey which provided him with innumerable lessons and positive takeaways.
Dyke-Davidoff-Masson Syndrome: A Case Report
Authors: Urs Gaurav M. , R Doddabele Hitesh
Published: March 2022

Background: Dyke Davidoff Masson syndrome (DDMS) is a neurological syndrome characterized by the presence of convulsions, facial asymmetry due to 7th nerve palsy, contralateral hemiplegia, and reduced intellectual capacity.
The Case: We report a case of DDMS in a 20-year-old male who is a previously known case of generalized epilepsy on medication presenting with status epilepticus and initially managed by anticonvulsants. On admission, the seizures manifested again which required the patient to be sedated with injectable anesthetics and intubated. Clinical examination showed no focal neurological deficits or neurocutaneous markers. Imaging studies showed characteristic features of DDMS which were hemiatrophy of the right cerebrum with calvarial thickening and sinuses showing hyperpneumatization on the same side as hemiatrophy. Previous history of such episodes had been recorded and the patient was kept on strict pharmacotherapy. Failure of adherence to these led to the current presentation. The diagnosis of DDMS was kept and the patient was treated conservatively with anticonvulsants and referred to a higher center for further management.
Conclusion: DDMS being a rare but important cause of refractory epilepsy is easily missed on initial assessment and failure of adequate management leads to higher rates of morbidity and mortality associated with this syndrome. In cases like these with an atypical presentation, a good background in radio imaging, and knowledge of the physical manifestations are required to arrive at its diagnosis.

Collaborative training for teaching probability and statistics: empirical approaches and simulation with elementary school students
Authors:   Universidade Federal do Amazonas, Souza Leandro
Published: March 2022

This paper presents a discussion of a case study conducted with the voluntary participation of sixteen mathematics teachers in the final years of elementary school in the state of São Paulo, Brazil. Research has shown that mathematics teachers feel insecure and sometimes use a linear and deterministic approach to teaching statistics. Based on this problem, a collaborative action research project has been developed. We analyze one of the activities planned in pairs and implemented by one of the teachers. Participants developed empirical activities on probabilistic and statistical themes and planned lessons with a focus on problem solving by simulation. It was evident that the teacher was a producer of knowledge that mobilizes that knowledge for the sake of generating teaching situations that promote student learning. During the teaching process, students misconceived luck, chance and causality, requiring the teacher to manage the process that allowed them to re-elaborate these ideas.
Estatísticas ambientais de água a partir da aplicação de coeficientes técnicos – um estudo de caso
Authors:   Instituto Brasileiro de Geografia e Estatística, Pereira Rodrigo , da Costa Julio ,   Instituto Brasileiro de Geografia e Estatística
Published: March 2022

Este estudo de caso consiste na aplicação de coeficientes técnicos nas estatísticas oficiais de produção industrial brasileira (2010), de forma a converte estatísticas econômicas em ambientais (recurso natural água). Ao aplicar os coeficientes máximos, as estatísticas de água obtidas para retirada, consumo e efluentes foram de 6,5, 2,7 e 4,1 bilhões de m3 respectivamente. Os resultados obtidos sugerem que a metodologia empregada é útil para e gestão dos recursos hídricos. Entretanto possui limitações importantes tais como significativas amplitudes observadas nos coeficientes e a reduzida quantidade de produtos contemplados, 27,7% do total de classes integrantes das estatísticas oficiais da produção industrial no Brasil em 2010. Tais limitações podem ser atenuadas pela aplicação dos princípios de educação ambiental na produção de estatísticas de água em bacias hidrográficas, integrando sociedade e instituições de ensino.

In general the undergraduate curriculum in statistics offers one semester basic course on linear programming (LP). The conventional course on LP includes simplex algorithm, duality theory, sensitivity analysis and some applications like the feedmix and transport problems. This outline seems to be distant from the mainstream curriculum in statistics. In order to partially overcome this shortcoming, we propose to introduce a technique based on linear programming called Data Envelopment Analysis (DEA) on the LP courses for students of statistics. DEA has gained momentum as a powerful complementary method for statistical tools in the research agenda as well as in practical activities of economic efficiency evaluation.
La incidencia de la formación matemática en el pensamiento probabilístico de los estudiantes
Authors:   Universidad Tecnológica Nacional, Regional Mendoza, Moreno Amable
Published: March 2022

Entre los estudiantes para profesor de Matemática, de la provincia de Mendoza, Argentina; hemos encontrado cuatro tendencias de pensamiento probabilístico: Determinista, Personalista, Incertidumbre y Contingente (Moreno & Cardeñoso,2014a, 2014b; Moreno, Cardeñoso & González-García, 2014c, 2014d). Sin embargo, no sabemos específicamente cuáles son las tendencias que poseen los estudiantes que se encuentran concluyendo su formación académica y que en un plazo muy corto de tiempo ejercerán la docencia. Por esta razón, hemos realizado un estudio con los ochenta y ocho estudiantes que se encuentran en esta situación, con el fin de determinar la incidencia de la formación matemática en el pensamiento probabilístico. Las respuestas de los estudiantes a un cuestionario revelaron la presencia de tres tendencias de pensamiento probabilístico: Determinista, Causalidad e Incertidumbre, que difieren de las encontradas en el conjunto de todos los estudiantes para profesor de Matemática.

Variability in the teaching of statistical literacy: a case of pedagogical dissonance?
Authors:   Mercy College, Hassad Rossi
Published: March 2022

Statistics education is a fast evolving discipline, and major advances have been made over the past two decades regarding reform of the introductory statistics course. There is now growing consensus that the introductory statistics course should seek to develop statistical literacy. The objective of this pilot study was to explore and describe self-reports of course learning outcomes and assessment strategies, as well as the extent to which instructors of introductory statistics at the college level emphasize statistical literacy. The results revealed that for a considerable proportion of instructors, what they think they are teaching is at variance with what and how they teach. If this gap is not addressed, it will quite likely result in students not being adequately prepared in statistical literacy, as well as misrepresentation of the type and quality of instruction. This gap or conflict between what instructors think they do and what they actually do, can be viewed as pedagogical dissonance, which can be attributed to a multiplicity of factors, addressed herein.
Reasoning with data or mathematical statistics? Is the uk moving in the right direction?
Authors:   Durham University, Nicholson James
Published: March 2022

Reasoning with data has been recognised as an important life skill for a number of years, but the statistics curriculum at school level has done little or nothing to prepare our young people to meet the challenges of working with large multivariate datasets. New curricula proposed for England seem to place an increasing emphasis on statistics as a branch of mathematics, and less on its role of making sense of the complex evidence in the world around us. The paper outlines the proposed curriculum developments, and discusses the proposed developments in the context of developments in the wider statistics community in respect of the use of hypothesis testing. It compares the direction of curriculum change with that of New Zealand and discuss the challenges facing the successful implementation of the new curriculum.

Published: March 2022

The system for biannual teachers’ evaluation made by students, acquires a large amount of information that becomes difficult to be analyzed by a manager. It is true that delivers a final score, but it is calculated based only on the answers to the questions with several pre-defined answer options. In their questionnaire, there are also open questions in which students can express themselves freely. These answers contain valuable information, but an educational manager needs a long time to read them all individually. In this paper is proposed an automatic module for interpreting the answers. The module will report to the educational manager only the answers that need to be analyzed. The module uses natural language processing techniques, and supervised machine learning for selecting the answers to be analyzed in a certain context.

Published: March 2022

The purpose of the present investigation is to perform a linguistic analysis of the English vocabulary of photography as a means of professional communication. The research includes a brief historical introduction to the progress of photography (diachronic approach) to study the (co)relationship between the development of photographic science and enrichment of its specialized lexical fund based on newly formed scientific concepts. The concept and quantitative analysis of the studied corpus established the predominance of the terminological units that are part of the conceptual groups, denoting the photo camera and its settings, photo editing and printing, lighting, photography metering, and issues. The ways of formation of English terminology of photography were investigated using structural, morphological, and componential analyses. The data acquired showed a variable number of terminological units formed according to various structural models. In the process of photographic terminology formation, substantive type of terminological combinations predominates, followed by the derivative units, simple and compound terminological units. Photography abbreviations as a form of language, time, and space economy were also structurally and semantically studied.

Conducting research in the prisons has its ups and downs. Majority of time, researchers face stress, rigor and challenges. It is documented that data collected in the prison shows poor response and high attrition rate. This article intends to share practical experience from the research carried out titled: Minnesota Multiphasic Personality Inventory -2- Restructured Form (MMPI-2-RF) profile of prisoners in Southwestern Nigeria and to showhow attrition rate and research bias can be managed and how prisoners can be recruitedwithout the use of coercion. It was found that the factors that cause a high rate of wear andtear analyzed the questionnaire at length, the cause being the ambiguity of the questionsand the desire of the respondents to thank the researchers. Therefore, it is necessary forresearchers to use questionnaires with fewer items, the language of the questionnaire shouldbe easy to understand and researchers should be careful of being sentimental with theprisoners.

Published: March 2022

The consumer is looking for good food and better nutrition. He understood very well that food and health are closely linked. What is confirmed today is the feeling of a change in the apparent balance of knowledge and power in relation to food, which requires some adjustment on the part of producers. This article, based on a review of the scientific literature, aims to understand how the use of the Internet changes the relationship between producer and consumer, resulting from the increase in the number of consumers of the Internet. According to the analysis, the development of food trade on the Internet contributes to changing this relationship between producer and consumer. The consumer no longer assumes the role of passive partner, but becomes more “empowered” or enters into more equal relations with brands thanks to digital devices.

A 57-year-old alcoholic woman with soft neck mass
Authors: Miranda Luiz Eduardo Correia , Miranda Ana Clara Galindo , Eufranio Matheus Stillner , Maia Maria Vitória Rocha Santos Bezerra
Published: March 2022

A 57-year-old woman was diagnosed with an anterior cervical mass (figure 1). No peripheral neuropathy or cervical lymph nodes were detected from the physical examination. The mass has slowly and painlessly grown for 30 years with no dyspnea or dysphagia. She had a history of chronic alcohol consumption and heavy tobacco use for 25 years. No standard medications were taken.

Multiple symmetric lipomatosis is a disease characterized by the accumulation of multiple, benign, symmetric, and nonencapsulated fatty tissue masses. This is more common in males (15:1) and in the Mediterranean population. Malignancy is rarely observed in this case. Masses can be found on the head and neck, including the upper trunk, shoulders, upper back, mediastinum, perineum, scrotum, and tongue. Besides the aesthetic effects, masses can cause airways or digestive compressive symptoms, as well as limitations in head or neck movements, urinating, or sexual intercourse. The involvement of peripheral nerves can cause neurological symptoms.

 

Alcohol abuse has been long associated with this disease.  A genetic cause has been suggested, but a hereditary pattern has not been identified in most cases. A link was suggested with liver disease, but there is no mention of liver abscess in the literature.

 

The diagnostic is based on image finds. Solitary lipoma is a benign soft tissue tumor, rarely found in the neck region. It mostly occurs in females and obese patients, and it is enclosed by a fibrous capsule that helps to differentiate it from other fat aggregations. Liposarcoma represents 1% of neck and head sarcomas. Patients are mostly men and the medium age is 70 years. Familial multiple lipomatosis is a rare autosomal dominant disease that is manifested in the thirties and is more prevalent in females (2:1). In this case, the discrete multiple subcutaneous nodules are movable, painless, and soft and have no associated conditions.

 

Lipectomy is the concerned treatment, but recurrence is common. Liposuction is an alternative to extensive lipectomy. No medicinal therapy is effective; however, alcohol abstinence can reduce the recurrence frequency.

 

Clinics must be aware of this uncommon disease in order to diagnose it and treat it appropriately.

Mindful compatibility of a Christian citizen while serving in the army of an earthly state
Authors: Levan Mateshvili Deacon
Published: March 2022

Recently, the currents of Christianity or other worldviews have become more frequent, the followers of which claim that service in the military formations of the state, protection of the homeland is connected with murder, which, in their opinion, violates the fundamental commandment of the Bible. The argument is the commandment of Christ about the love of the enemy and the second cheek. These views, at first glance, indeed find their basis in Scripture, but only at first glance. The question is: can the Christian Church justify the war paid for the defense of the homeland and, consequently, the forced murder of the enemy, the theological death of the enemy? Of course it can. His paper is quite strong and argumentative, based on Scripture, and presents the vain, sectarian, and narrow-minded thinking of pseudo-peacekeepers.
Internet e juventude: desafios da contemporaneidade
Authors: Barreto Junior Alfeu
Published: March 2022

Discutir como os indivíduos se relacionam com a internet é um assunto que está na ordem do dia. Torna-se irrelevante fazer referência aos nativos (jovens) ou imigrantes digitais (adultos), uma vez que as Tecnologias de Comunicação e Informação estão direta ou indiretamente presentes na vida de boa parte dos brasileiros. No contexto dessa relação, este artigo observa a influência da internet na formação identitária da camada da sociedade mais “imersa” na internet: a juventude. Definir o que é ser jovem é uma tarefa árdua, mas delineia-se aqui aquele diretamente ligado à prática docente: alunos de nível fundamental e médio. Assim, autores com visões utópicas e distópicas, advindos do meio acadêmico ou das artes, são brevemente apresentados como forma de proporcionar uma reflexão sobre os desafios apresentados pela contemporaneidade na qual a juventude está “conectada”, como forma de buscar ações que possam articular a ação pedagógica a esse contexto.
Prostate - Specific Antigen, an Effective Screening Tool for Prostate Cancer - An Analysis of 932 TRUS Core Needle Biopsies
Authors: Lila Kunjal , Chadha Kirti , Barodawala Shaikhali M
Published: March 2022

Prostate cancer is the second most frequent cancer and the fifth leading cause of cancer death among men in 2020. Since it is a slow growing tumour, an early detection leads to better chance of successful treatment. Prostate-Specific Antigen (PSA) is a protein found exclusively in prostatic tissue. It is elevated in different prostatic pathologies apart from carcinoma.
A cohort of 932 prostatic core needle biopsies was selected after necessary exclusions. The routine haematoxylin & eosin and immunohistochemistry slides were retrieved along with the histopathologic diagnosis rendered. The diagnosis was then correlated with PSA.
The mean age for diagnosis of prostatic disease and carcinoma was 68.39 years and 70.21 years respectively. 50.50% cases were premalignant or malignant whereas the remaining 49.50% cases were benign. A cut-off of 4 ng/ml had a sensitivity of 99.78% and a specificity of 7.33%. Gleason score 8 and 9 were most common, accounting for 56.39% of the malignant cases.
The present study showed a statistical correlation of age and PSA with prostatic carcinoma. PSA is a valid and sensitive marker and may be continued as an early marker for the screening of prostate cancer. The risk of cancer is minimal with a PSA less than 4 ng/ml whereas an elevated PSA is associated with pathology and hence even a borderline elevation should not be ignored. Due to a low specificity, PSA needs to be corroborated with DRE and transrectal ultrasonography followed by biopsy in cases with PSA > 4ng/ml.

Key words: Prostate, Prostate - Specific Antigen, Prostatic Adenocarcinoma, Benign Prostatic Hyperplasia.
Cardiopulmonary Resuscitation Knowledge among Physiotherapy Students in Ahmedabad
Authors: Chauhan Jalpakunvarba Prabhatsinh , Patel Hemal
Published: March 2022

Background: Cardiopulmonary resuscitation reduces cardiac arrests and associated deaths when patients receive prompt CPR from trained healthcare professionals. Physiotherapists, using exercise as a therapeutic approach, need to have good CPR knowledge and skills not only to deal with possible adverse cardiac events during exercise but also because the widespread application of CPR and early defibrillation can significantly reduce mortality from a heart attack. In this study, we assessed cardiopulmonary resuscitation knowledge among physiotherapy students in Ahmedabad.
Aims and Objective: This study aimed to assess CPR knowledge among physiotherapy students in Ahmedabad.
Method: A cross-sectional study of physiotherapy students in Ahmedabad was conducted. An online survey was conducted with a self-administered questionnaire. The data was collected from 191 physiotherapy students in Ahmedabad aged 18-25 years.

A Case Report on the Impact of Physiotherapy on Shoulder Function in Breast Cancer Patients Undergoing Surgery
Authors: Khurana Shilpa , Rathi Namrata , Jaiswal Leena
Published: March 2022

Early breast cancer treatment can cause shoulder dysfunction, which is a well-known and prevalent adverse effect (1). In individuals treated surgically for breast cancer, physiotherapy was found to enhance shoulder function considerably (1). Breast cancer is the most common type of cancer in women and the leading cause of death and morbidity (2). Every year, 1.67 million new instances of breast cancer are identified worldwide, with 458,000 fatalities (2). Although 89 percent of breast cancer survivors live for at least five years after treatment, side symptoms can continue for months or even years(2). The most common upper-limb side effects are pain and joint dysfunction, with prevalence rates ranging from 12% to 51% for pain and 1.5 percent to 50% for joint dysfunction. Surgery is the most common treatment for primary breast cancer. Shoulder exercises are commonly advised to reduce mobility and strength loss as well as prevent lymphedema. Several clinical services have been developed to help with shoulder range of motion rehabilitation and secondary lymphedema prevention(3) . The goal of this study was to see how additional postoperative physiotherapy affected shoulder function after the initial postoperative healing period, especially when given for a longer period. Patients who have had a mastectomy are always at risk of getting shoulder pain and adhesive capsulitis, and they must take precautions (3).

Breast cancer has been the most common cancer in the United Kingdom since 1997, accounting for 31% of all new cancer diagnoses in women. The rate of new diagnoses among people over 40 years old rises fast, from under 1 per 100,000 in young adults to well over 400 per 100,000 in those over 85 years old (1). Breast cancer survival rates are improving as a result of breakthroughs in diagnosis and therapy, and cancer survivorship has emerged as a major focus in the cancer care continuum. (2). Cancer rehabilitation is defined as the process of aiding a patient in attaining the best level of physical, psychological, social, sexual, vocational, recreational, and economic functioning possible within the restrictions of the disease and therapy. (2). Pain, lymphedema, secondary malignancies, and sexual dysfunction are among the possible long-term physical repercussions of cancer (2). Fear and anxiety about return of cancer, sadness, and emotions of uncertainty and loneliness are all possible psychological consequences. (2). Changes in interpersonal connections, financial and health insurance concerns and difficulty returning to work or seeking employment owing to impairment are all examples of social impacts (2). Even though recent advancements in therapy have increased survival rates, they are also associated with considerable adverse effects (3). Breast cancer survival rates have increased as a result of breakthroughs in early detection procedures, followed by more tailored and/or aggressive therapy (3). Although breast cancer patients' rehabilitation has become a priority in recent years, additional research on the most effective sorts of therapies is still needed. (3).

A possibility of increasing wear resistance of Ti6Al4V alloy after cathodic plasma electrolytic nitriding in a solution of ammonium chloride and ammonia is shown. The competing effect of the surface erosion by the actions of discharges and high-temperature oxidation on the morphology and roughness of the surface was revealed. The complex effect of the surface roughness and surface layer hardness on the wear resistance of the titanium alloy was determined. It was found that the greatest decrease in the weight wear by a factor of 2.7 was observed for the sample with the maximum microhardness of the surface layer, reaching 820 HV, and the smallest surface roughness. It was shown that the friction coefficient decreased in proportion to the treatment time when the surface layer had low hardness, favoring the sliding of the counter-body.

Published: March 2022

The results of investigations of electrohydrodynamic (EHD) flows using the schlieren method in the following systems of electrodes: “a blade – isolated edge blade”, “a blade – two rods”, and “a rod with a perforated isolation coating – two rods” are presented. On the base of the obtained results, single-stage EHD pumps were designed. Their head and flow specifications were studied depending on various factors. It was shown that the performance of the EHD pumps can be increased by application of dielectric coatings on the electrodes. The maximal efficiency was obtained in the system of electrodes “a blade – a blade with isolated edge”, the maximal static pressure – in a three-rod system with a perforated isolation coating of the emitter. The advantages of a three-rod system were specified related to the improvement of the flow characteristics of the pumps due to their parallel arrangement and increasing of the pump pressure by using multi-stage pumps with grid electrodes.

The analysis and generalization of the results of studies of high-voltage electrochemical explosions (HVECHE) proceeding under various conditions, driven by special aspects and needs of the existing HVECHE based pulse-discharge technologies, was carried out. A methodology to calculate combined energy sources is proposed in relation to the needs of various discharge-pulse technologies using a high-voltage electrochemical explosion. Based on the analysis of the results of experimental studies, the advantage of using a high-voltage electrochemical explosion with a controlled input of electrical energy into the discharge channel was substantiated. An algorithm was developed to calculate the parameters of a combined electric-discharge source of a controlled HVECHE and the required mass of the exothermic composition which provides the energy characteristics specified by a specific discharge-pulse technology. The results of testing the developed calculation algorithm are presented confirming the possibility of its use for engineering calculations of combined power sources with a controlled input of electrical energy into the discharge channel.
