Acceso de grupos indígenas a la educación integral: una buena práctica en la formación docente en Costa Rica
Authors: Vargas Jiménez Ileana , Vargas Dengo Marie Claire
Published: August 2021

The article arises as a result of the project of Education in Values and Human Rights in Teacher Training. Through the project, a teacher training experience was selected which was developed with a Costa Rican indigenous population; the experience is located at the Universidad Nacional and, for the purposes of the present article, it is called good practice in university teaching. Key participants were interviewed about what they consider to be good practice, what is human rights and values education. The results are analyzed from a qualitative perspective, and demonstrated that good practice, is a pertinent and respectful education of indigenous culture. It is concluded that in pedagogical practice, values must be approached in an integral manner.
La inversión de la concepción de los Derechos Humanos y su uso en América Latina
Authors: Barrera Rivera Dan Abner
Published: August 2021

In the present article an approximation will be made to the formulation fashioned by the West of the concept of human rights; it is a bourgeois conception that inverts the meaning of human rights, where the priority is private property. To understand and explain this reversal, resource is made to some works by Franz Hinkelammert, one of the premier thinkers on the subject matter. Then it is suggested that this inversion of human rights is closely related to capitalist and neoliberal democracy; it is exposed how in Latin America bourgeois democracies are the appropriate platform for the application of the market economy, whose conception of human rights consists of such inverted vision that, in the name of freedom of enterprise, democracy and of this formulation of rights human rights, denies, reduces, removes, disapproves of and violates human rights. This situation is shown by way of contrast with the achievements had by some leftist governments during the first three decades of the 21st century and it concludes by exposing what Cuba―an economically blocked country―has done for human rights, from a perspective opposite to that of the bourgeois vision of human rights.

Social protection has become a very relevant instrument from which every society intertwines activities to build social groups with greater well-being, where every individual has access to fair and inclusive treatment, within a context of freedom and permanent social progress. Thus, social protection has been considered as a process that strengthens the application of human rights. This document makes an analysis of social protection and its relationship with progress in this area in Mexico, in the context of human rights.
Vuelta a la patria en tiempos desesperados: Imaginarios sociales en torno a los retornados a Petare-Venezuela en época de pandemia
Authors: Gómez Castillo Suzuky Margarita , Molina Castro Diógenes José
Published: August 2021

The purpose of this research is to characterize the social imaginaries that emerge from the life stories, around the returnees to the El Carpintero de Petare sector in Miranda-Venezuela, the scene of the investigation, during the time of the pandemic. The present work is a type of qualitative research, from the interpretive paradigm with a biographical approach and narrative design, from the perspective of the life story. Among the theoretical postulates treated, it is worth mentioning; The imaginary institution of society (Castoriadis, 1993), Life History (Ferraroti, 2008) and Self-care deficit theory (Orem, 1991). Among the results, it is worth mentioning that public prevention policies against COVID-19 cannot be proposed under conditions that stigmatize and produce fear and suspicion in the community. This cannot be considered a productive way to control infections.
El derecho humano al agua: una deuda del estado con la población panameña
Authors: Díaz-Ríos Tomás
Published: August 2021

Panama is a favored country in terms of water resources; however, it is observed that 10% of the population of the Republic lacks access to drinking water. Based on international instruments and commitments to the Millennium Development Goals and the Sustainable Development Goals of the United Nations, the “human right to drinking water” will be based on the new constitutional reforms derived from university work. The main objective of the present study is to allow legal instruments to reach, through constitutional guarantees, the most vulnerable population. Its application will be through comparative law. Employed methodology was by means of observation and analysis of secondary sources and data. The statistics provided by the Planning Directorate of the National Aqueducts and Sewers Institute (IDAAN) were used. This article is part of the research section of the doctoral thesis “The water footprint; an indicator to apply to the circularity of water: sustainable management model for Panama”. Incorporation of the text on the human right to water in the Political Constitution of the Republic of Panama will pay for the delay that the State has had with the Panamanian population, and the international agreements signed. The criteria analyzed will serve to reflect on the issues of water management and governance; and will allow advances in the matter of human rights to water, it will help advance the emphasis on the recognition of the “human right to water for Panama”.
Pedagogía teatral y derechos humanos: una puerta para el autoconocimiento
Authors: Burmeister G. Sandra S.
Published: August 2021

The importance of research on human rights education through theater pedagogy is that it addresses an active methodology in the classroom that allows understanding theoretical content through individual and group experience from a daily perspective of self-knowledge. This signifies that it sensitizes the participants in human rights, addressing the conflict through theatrical play, which stimulates divergent thinking, and the controversial dialogue that develops critical thinking leading to new knowledge. The research method was qualitative, since it was worked from a legal approach and around the qualitative aspects of the subject of law.  Execution was based on participant and non-participant observation, the creation of a focus group, interviews and content analysis. In this case, the chosen universe was a limited group of school education teachers. Instruments such as forms, interviews, talks and teaching practice with the age group were used to record the information obtained. In conclusion, it was an interactive and participatory investigation that fostered didactics and yielded relevant data for the systematization of human rights education through theater pedagogy.
El feminismo de cara al acceso a la justicia para las mujeres
Authors: Rocha Martínez Verónica Ethel
Published: August 2021

The present exposition is an analysis that deepens and narrates the circumstances of life of women when they demand justice before the administrating authorities. It shows from the documentary, hemerographic and testimonial contribution, the context of impunity and transgression upon the denunciation of gender crimes. It explains the efforts and emergence of feminist groups in order to provide legal and emotional support to victims, but it is also a document that proposes to strengthen the capacity to reinterpret, build and base gender identity on parameters other than objectification and abuse.
Una lectura tanatopolítica de Bandada de pájaros: segundo ensayo sobre la memoria de Jorgelina Cerritos
Authors: Leandro Hernández Lucía
Published: August 2021

This article makes a reading of the dramaturgical work Bandada de pájaros: segundo ensayo sobre la memoria (2016) by Jorgelina Cerritos (San Salvador, 1974) from a thanatopolitical perspective. It inquires about the power exercised by the Salvadoran State in the life of the citizens, represented by characters who, deprived of their category of person, see all their rights interrupted. These subjects are members of a community who become a potential threat to be suppressed by the State. Furthermore, it analyzes the vulnerability of women to the heteropatriarchal warlike apparatus and the possibilities of theater as a space for the construction of a memory that restores the memory and identity of the thousands of disappeared during the Salvadoran civil war.
La sirvienta y el luchador (2011) y Moronga (2018) de Horacio Castellanos Moya
Authors: Bezhanova Olga
Published: August 2021

This article analyzes two novels by the Honduran-Salvadoran writer Horacio Castellanos Moya, La sirvienta y el luchador (2011) y Moronga (2018), and demonstrates that the author’s novelistic output represents a complex and all-encompassing whole. Readers glean information not only from the novels themselves but also from the space between these works of literature where many crucial historic events take place and the characters evolve. Each of Castellanos Moya’s novels can be read and enjoyed without having read his preceding work, yet the readers’ capacity to understand the nuance of each novel is deeply impacted by whether they have been able to access the interstices between the two novels.
Reggae y ethos rastafari
Authors: Valero Arnaldo E.
Published: August 2021

This article seeks to point out that singers such as Bob Marley, Bunny Wailer and Peter Tosh have exercised a kind of tribal education that has allowed the Rastafarian community to learn about the patterns of social and moral behavior that have come to be considered emblematic of their value system. To achieve our purpose we will quote and gloss a set of songs from that musical genre that over the decades has proclaimed the divine nature of Haile Selassie, the idea of a return to Africa, the historical and political importance of Marcus Garvey, the sacramental character of the marijuana use and the symbolic value of dreadlocks.
El uso de los biomodelos didácticos en las ciencias veterinarias: Una revision.
Authors: Balaguera Quinche David Fernando , Vesga Castillejo Javier Arturo , Burgos Guzmán Andrés Laureano , Simbaqueva Peña Jeyson Simbaqueva , Rodríguez Rodríguez Jhoan Sebastián , Córdoba Parra Juan David
Published: August 2021

Didactic models have been used throughout many years as a means for understanding human and animal medicine, especially in subjects such as anatomy, physiology, surgery, and pathology that are central to the training of the medical professional. These models are three-dimensional artificial models that seek an approximation to the morphology and function of an organism, help its exploration and, if possible, a replacement to reduce practices with animal experimentation. This literature review was constructed by searching different sources, and the authors’ own didactic exercises will also be presented to highlight some important aspects of the use of didactic biomodels from different disciplines of veterinary medicine and also different points of view for their implementation as a tool to promote the teaching-learning process in students.

El Bicentenario de Centroamérica desde el enfoque de los jóvenes universitarios
Authors: Hernández Monterroza Marni Lorena
Published: August 2021

The article is based on the thesis that every time we move further away from a historical event, we run the risk of understanding less its meaning and therefore its importance if it is not taught in a meaningful way. The objective of this research is to estimate the meaning that the commemoration of the Bicentennial of the Central American Independence has for young university students. The methodology used was the application of the survey technique to young university students between 18 and 22 years old, enrolled in humanistic careers and who have taken the subject of History of El Salvador. For there to be a true historical meaning of the commemoration of the Bicentennial and to transcend rote learning, the teacher who teaches the subject of history must change and adapt his didactic style to achieve the objective of forming citizens with historical roots of identity and not a simple rote learning.
Perspectivas, cambios y resignificación de la enseñanza de la historia en Honduras del Bicentenario
Authors: Guevara Pineda Erick José
Published: August 2021

The new social dynamics have caused a significant turn in the teaching of the social sciences and particularly in history. The purpose of this article is to present a non-experimental descriptive case study; developed at the Choluteca associated center of the Metropolitan University of Honduras -located in the municipality of Choluteca- and the Villa Marco Official Institute -located in the municipality of Marcovia- in the southern region of Honduras. Which have allowed the marking of elements to be deconstructed for the understanding of the processes that as bicentennial societies we must consolidate or re-signify. This work deals with the need to merge the history taught by the researched, coupling a new vision of how to approach the curricular contents, the strengthening of decision-making by students and some considerations that as teachers in virtual or blended interaction we must assert itself in the Honduras of the XXI century; such as the proper dosage of the contents, the management of platforms or virtual classrooms, as well as games in real time that allow the idea of constant interaction and the monitoring of the students who deserve it with the greatest need.
Anforderung an das Verbot der Marktmanipulation in illiquiden Märkten
Authors: Mock Sebastian
Published: August 2021

Mit der vorliegenden Entscheidung des EFTA-Gerichtshofs hat sich erstmals ein europäisches Gericht zur Auslegung der Vorschriften zum Verbot der Marktmanipulation nach Art. 1 Abs. 2 Marktmissbrauchsrichtlinie (2003/6/EG) geäußert. Dass es sich dabei nicht um den EuGH, sondern um den EFTA-Gerichtshof handelt, mag auf den ersten Blick etwas gewöhnungsbedürftig sein, ändert aber nichts an der Relevanz für die Auslegung der Marktmissbrauchsrichtlinie und auch der diese ersetzenden Marktmissbrauchsverordnung (MAR), da die Regelungen zur Marktmanipulation nahezu unverändert in deren Art. 12, 15 übernommen wurden.

Objectives: The introduction of cesarean section categorization and recommendations on decision to delivery interval was a major step forward towards standardizing clinical response to obstetric emergencies. The recommended decision to delivery interval (DDI) for category 1 cesarean sections is 30 minutes, however there is a balance to be struck to ensure that reducing fetal hypoxic risk is not at the expense of increasing maternal and fetal morbidity. The aim of the study was to review category 1 cesarean sections, focusing on reasons for delays and neonatal outcomes. Design: The study was conducted as a quality improvement initiative to review the performance of the institution in managing women delivered as category 1 cesarean section between January 2020 and August 2020. Methods: The data was extracted from the operating theatre log book and patient electronic records (Cerner system) and analyzed using SPSS statistics package. Results: There were 577 cases of category 1 Cesarean section undertaken during the study period. The recommended DDI of 30 minutes was achieved in 385/577 (67%) of cases but was exceeded in 192/577 (33%) of cases. The most common indication of category 1 cesarean section was fetal distress (58%). It was noted that significantly more women (88.8%) in the <30-minute group had the decision taken in the labor ward, which is in close proximity to the obstetric theatre. Significantly more women in the <30-minute group had epidural or general anesthesia. Significant delays in the preparation time, transfer time, anesthesia time and delivery time were noted in the >30-minute group. The neonates in the <30-minute group had significantly lower pH and base excess measurements at birth however fewer were admitted to the neonatal intensive care unit. Conclusion: This study has demonstrated that only two thirds of category 1 cesarean deliveries are performed within the 30-minute recommendation. The delays were evident at every stage of the process of performing the cesarean. There are some factors which are not modifiable such as non labor ward transfers. Continued monitoring of category 1 cesarean outcomes is recommended.
Bio-adsorption of methylene blue dye using chitosan-extracted from Fenneropenaeus indicus shrimp shell waste
Authors: Arunachalam Kantha D
Published: August 2021

The cationic dye “Methylene blue” is widely used in textiles industry, pharmaceuticals, paper industries, and ink manufacturing etc, The washed off dyes discharged directly in water bodies and cause major damage to the environment. The molecule of dye is very stable, so that it is very difficult to decompose naturally. Therefore, it is essential to remove the dye by purifying, and prevent the environment from pollution. The –NH2 and -OH functional groups of Chitosan can induce the adsorbing capacity of dyes by its low surface area, porosity and high crystalline nature. Chitosan is an environment friendly, non-toxic, easily available, biodegradable, renewable biopolymer, and harmless to biota. Extraction of chitosan from the “Fenneropenaeus indicus” (Shrimp) shell and its utilization in wastewater treatment controls the environmental problems and contributes to solid waste management. In this study, the possible use of “Fenneropenaeus indicus” (Shrimp) shell chitosan for the bio-adsorption of MB dye was investigated by a batch adsorption method using different adsorbent doses with respect to experimental duration. The maximum amount of dye adsorption was obtained at a minimum dose of 4gram chitosan, with experimental time of 4 hours. The Fenneropenaeus indicus shell chitosan was found to be a better adsorbent since it removes about 93.23% of methylene blue dye from sample water. Further, characterization of functional groups was also done and the changes of groups were observed from both control and treated samples.

Published: August 2021

The objectives of this study are to review epidemiology, novel methods of detection, novel diagnostics, and novel therapeutic options of malignant pleural mesothelioma (MPM) in the literature that were published between 1977 and 2019. Malignant pleural mesothelioma, associated with prolonged respirable-asbestos-fiber exposure is a rare cancer with constantly increasing incidence and poor prognosis due to lacking the effective treatment options. The median survival ranges from 8 to 14 months. Sarcomatoid histological subtype has the worst prognosis. Video-assisted thoracoscopy plus mediastinoscopy is the current gold standard for staging malignant pleural mesothelioma and is superior to computerized tomography of the chest for assessing the tumor size and suspected nodal metastases. Several circulating biomarkers are detected in MPM patients, such as mesothelin, osteopontin, fibulin-3, high mobility group B1, vascular endothelial growth factor, reactive oxygen species, reactive nitrogen species, micro-ribonucleic acids, tumor deoxyribonucleic acid, etc.Surgery is controversial and restricted to patients with early stage disease and good functional status. There is still no curative treatment whereas chemotherapy is the only treatment modality that improve patients’ survival. Radiotherapy is beneficial as a palliative treatment and an adjuvant to chemotherapy and surgery in the context of trimodality treatment. In conclusion, there is potential for the development of biomarkers and radiological imaging in the years to come. Several novel therapeutic options are under studied and it is likely to involve highly personalized treatment. Its incidenceis expected to decrease in the next decade.

Authors: Tangsawad Watcharachai
Published: August 2021

Background: The purpose of this study was to evaluate the result of the multilevel single-stage procedure for obstructive sleep apnea (OSA) with a narrow nasal cavity and oropharyngeal, velopharyngeal airspace. A retrospective study was performed in OSA patients who underwent surgery in Khon Kaen hospital, Thailand. Methods: A retrospective study was conducted and medical records were reviewed between 2015 May and 2019 November in patients with loud snoring and having symptoms and signs of OSA, 43 patients included for evaluation history taking and physical examination by fiberoptic laryngoscope and performed multilevel single-stage procedure and evaluated clinical postoperative. Results: All patients were evaluated preoperatively by a history taking and physical examination for clinical assessment including fiberoptic laryngoscope examination. There were 3 surgical procedure, Procedure 1: 12 patients underwent Tonsillectomy with uvulopalatopharyngoplasty (27.9%), Procedure 2: 22 patients underwent Tonsillectomy with uvulopalatopharyngoplasty and inferior turbinoplasty (51.2%), Procedure 3: 9 patients underwent Tonsillectomy with uvulopalatopharyngoplasty and inferior turbinoplasty, and septoplasty (20.9%). After a 1-week post-operation 41 patients (95.3%), all (100.0%) no symptoms of OSA, and 60.9% improved their loud snoring more than 80.0%. After 3-week post-operation, 32 patients (74.4%) followed up and all (100.0%) no symptoms of OSA, 27 patients (84.4%) improved their loud snoring by more than 80.0%. Conclusion: Clinical assessment in patient with OSA is important before treatment. The Multilevel single-stage procedure is alternative choice for first treatment of OSA patients who reject continuous positive airway pressure (CPAP) or failure using CPAP. The results outcome is good for both obesity and non-obesity patients and improve clinical in OSA.
Efficacy and safety of Hydroxychloroquine in treating COVID-19 pneumonia: uncertainty of data and changing treatment protocols
Authors: Fadelelmoula Tarig
Published: August 2021

The new coronavirus disease which emerged in Wuhan late in 2019 is caused by SARS CoV2, it was named COVID-19 and declared a pandemic by the world health organization (WHO). Human coronavirus normally causes mild disease. The new COVID-19 emerged from bats to human and it’s associated with highly infectious disease. The disease clinical features range from an asymptomatic state to mild fever, cough, severe respiratory disease, and multiple organ failures. The disease is confirmed by detecting the virus genome using polymerase chain reaction and antibody detection is used for screening. Radiologic imaging is nonspecific but can help in staging lung involvement. Treatment of patients with COVID-19 is generally supportive, however oxygen and ventilatory support might be needed in some of the cases. Dexamethasone proved to decrease mortality in critically ill patients, but up to date no specific treatment or vaccine is available and many drugs are under clinical trials including ritonavir and remdesivir. Hydroxychloroquine (HCQ) which is an old antimalarial drug, has given hope, but now it’s a victim for information uncertainty and contravention of clinical reports. The objective of this article is to review the current reports on hydroxychloroquine efficacy and safety in the treatment of COVID 19 patients.
Nasal secretion insufficiency syndrome (new concept of ozena)
Authors: Takami Toshiro
Published: August 2021

The patient complained of nasal odor and was referred to a psychiatrist by the Department of Otolaryngology as a case of olfactory reference syndrome. The patient had a strong nasal odor. The doctor denied the existence of atrophic rhinitis and rhinophobia. If you look around the internet, there are many who suffer from similar conditions. Almost all of them complain of an unusually dry nose. It was thought that Pseudomonas aeruginosa or some fungus grew abnormally in the devastated nasal mucosa of the endogenous nasal cavity, and due to inadequate nasal secretion, the bacterial metabolites could not be forced down the throat or other parts of the body, giving off a strong nasal odor. This disorder is often neglected or diagnosed by psychiatrists as olfactory reference syndrome. The term "nasal secretion insufficiency syndrome" is used to describe this condition. This is a new concept of nasal odor disease, which remains unnoticed, partly because there is no crusting or atrophy of the native nasal cavity, and partly because endoscopy reveals only the devastation of the nasal mucosa, and partly because it is hidden behind the veil of atrophic rhinitis and ozena. In all seven cases, the foul odor is weakened, albeit temporarily, by the use of saliva-enhancing drugs.

Authors: Báez Maria Valeria Jiménez
Published: August 2021

Introduction: Kaposi's sarcoma is a neoplasm associated with the Human Immunodeficiency Virus (HIV) - AIDS especially in advanced stages, in Quintana Roo HIV-AIDS ranks first in the country. Methodology: A series of 22 cases with diagnosis confirmed by biopsy attended by the oncology service of HGR No. 17 is presented. Results: They were classified as low risk (4); three of them with complete response. High risk (18); fifteen accepted chemotherapy. Nine (60%) received liposomal doxorubicin and six (40%) paclitaxel; of these, four had a complete response, one partial response, six with stable disease and five with disease progression that required a second line. The presence of adverse effects associated with chemotherapy treatment was documented in six patients classified as high risk (40%). Conclusions: Clinical interventions with therapeutic trials are necessary, since the available evidence dates from periods of more than 10 years ago. HIV patients require continuous monitoring and clinical trials to improve the therapeutic options available to treat one of the most common oncological diseases in this population such as Kaposi's Sarcoma.
Bioaccumulation of heavy metals in Oreochromis niloticus (Linn.1758) of Agodi Reservoir, Ibadan, Nigeria
Authors: PO Ogungbile , Akande JA , Adepoju AO , Ogunbode TO , Sridhar MKC
Published: August 2021

The concentration of Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn in Oreochromis niloticus(generally called Tilapia fish) was assessed at three different locations along Agodi Reservoir in Ibadan. Their relative concentrations were determined using Atomic Absorption Spectrophotometer (AAS). Test location differences and seasonal variations of the values were examined using statistical analysis of variance at P<0.05 to establish pollution dynamics. The results showed declining order of heavy metal concentrations in the order of Mn>Fe>Zn>Cu>Co>Cd>Pb>Ni. Gradient effect was indicated. While Cd was found in decreasing order of concentration from inlet to the outlet, other metals like Co, Cu, Fe, Mn, Ni, Pb, and Zn had concentrations that gradually increased from inlet to the outlet.The concentration of Cd, Co, Cu, Pb, and Zn did not change considerably with season unlike Fe, Mn, and Ni that exhibited substantial seasonal variation. It was concluded that heavy metal accumulation caused marked pollution dynamics inside the Agodi Reservoir. Also, bio-accumulation of the metals in Oreochromis niloticus could give birth to location and seasonal dependency.

Published: August 2021

Biodiversity is defined as the variety of life encompassing the ‘existing’ variations at all level, starting from the tiny genes within a species up to a broader sense consisted of habitats within ecosystem. It is urgently needed as long as human is still exist on this earth. Therefore, its proper utilization and correct application of biodiversity bring great advantage in tangible and non-tangible benefits. Indonesia is known as the third largest biodiversity hotspots; both its flora and fauna. It has also tremendous diverse ecosystems extended from west to east; with amplitude of variation ranging from humid tropical rain forests until a very dry savannah type at the eastern part of Nusa Tenggara. Furthermore, Indonesia is also known as the fourth world highest producer of coffee; with a total production 11,49 million kg in 2016-2017. The Gayo highlands on the northern tip of Sumatra are known as the major production of arabica coffee. There, up to ten varieties of commercial arabica coffee are planted on the highlands. The origin of coffee is in Ethiopia, which is believed as the center of the commercial coffee species in this world: C. arabica and C. canephora. The objective of this paper is to review the status of coffee, esp. the arabica one from various perspectives, ranging from the biology, history of coffee, the processing of coffee (wet vs. dry methods), and how the component of natural biodiversity can be applied in order to enhance the coffee production, particularly on the Gayo highlands.
Uterine stump leiomyosarcoma after sub-total hysterectomy: a case report
Authors: Wahab Haitham Abdel , Ayaty Mohamed , Abdallah Mohamed , Elghandor Ahmed
Published: August 2021

Introduction: Uterine sarcomas considered as one of the aggressive tumors of uterine malignancies. It is one of the mesenchymal tumors that originate from smooth muscle of the uterus which is a rare tumor that accounts for 2% to 5% of all uterine malignancies. Very few cases are reported in the literature. Our patient has a unique history of Pelvic-Abdominal swelling reaching xiphisternum level after subtotal hysterectomy one year ago. Abnormal genital bleeding not responding to medical treatment is the usual presentation in uterine sarcoma like in our patient. We report an original case report of an abnormal sequence of this rare tumor arising from the uterine stump after subtotal hysterectomy. Case presentation: A 42-year-old nulliparous woman presented to our gyne-oncology unit in El-Galaa Maternity Teaching Hospital in June 2020 with a significant rapid increase in abdominal circumference, symptoms caused by abdominal pressure (vomiting and constipation) and abnormal genital bleeding after laparotomic sub-total hysterectomy one year ago. Tumor marker CA-125 was raised, LDH was raised and a MRI scan showed a huge mass arising from the pelvis. An exploratory laparotomy was performed and the histopathology report confirmed the diagnosis of uterine leiomyosarcoma weighing around 22kg. Conclusion: Because of their rarity, uterine sarcomas are not suitable for screening. Diagnosis by histopathologic examination and surgery is the only treatment. Pre-operative MRI with contrast for abdomen and pelvis is highly recommended to exclude abdomen metastatic sarcoma if the tumor is confined to the pelvis only.

Introduction. The multifunctional magnetodynamic tundish prototype is the first world magnetodynamic mixer and batcher for steel, which has a capacity of up to 10 tons of melt and an inductor electric power of 600 kW. Ithas been successfully introduced into industry. Further works aim at adapting this device to continuous casting, in particular at obtaining semi-continuous cast billets at metallurgical micro-plants.Problem Statement. Today, the study of the effect of electromagnetic field on melt stirring and removal of non-metallics in the inlet chamber of MD-T is an urgent task.Purpose. The purpose of this research is to substantiate and to create MD-T as a two-chamber aggregate additionally equipped with a few electromagnetic & MHD devices for different purposes, to be used at metallurgical micro-mills.Materials and Methods. Physical modelling has been applied for studying liquid metal stirring under the action of electromagnetic field and the removal of non-metallics.Results. The behavior of the liquid jet falling from the ladle into the centrifugal chamber has been studied. The influence of the rational liquid level in the centrifugal chamber, which is exposed to the direct action of the electromagnetic field, has been estimated. It has been established that the effect of rotation of the total liquid volumehas been achieved at the height of application of electromagnetic field, which is 0.2—0.3 of the total fill height. Increasing the height of the application of a magnetic field leads to the capture of the upper layers of the liquid.Conclusions. There have been proposed a new design of magnetodynamic tundish (MD-T) for continuous casting of steel. The use of tundish with a rotational motion of the flow may significantly reduce the number of large oxide inclusions (larger than 10 µm) in steel. The device has been successfully tested and its application will improve the quality of cast billets, extend the functionality of equipment and technologies, and enable the realization of modern high-efficiency processes of continuous casting.

Introduction. It is important to decrease light and heavy impurities influxes towards the plasma volume during the high temperature plasma experiments in fusion devices. This is why the conditioning of the wall inner vacuumsurfaces is a basic part of the fusion device operation.Problem Statement. The conventional inner vacuum chamber surface conditioning methods has a significant drawback: sputtering materials in a vacuum chamber. The inner vacuum surfaces can be also conditioned with radio-frequency (RF) discharge plasma, but the conditioning effectiveness is limited by low ion energy.Purpose. The purpose of this research is to develop vacuum surface conditioning technology by the radio frequency plasma combined with DC discharge.
Materials and Methods. The noncontact passive method of optical plasma spectroscopy has been used to estimate ion plasma composition. The stainless steel outgassing has been determined in situ with the thermodesorption probe method. The sputtering of the samples has been measured with the weight loss method.Results. The studies of combined discharge have shown that: the anode voltage of combined discharge is lower than in case of the glow discharge; the stainless steel 12Kh18N10T erosion coefficient is about 1.5 times less in thecase of combined discharge than in the glow one; the thermal desorption diagnostic of wall conditions in the DSM-1 has shown better efficiency with the combined discharge as compared with the glow discharge. Theproposed technology is an original one and has no analogs.Conclusions. The reported research results have shown good prospects for the combined discharge usage for plasma walls conditioning and opportunities for using the combined discharge technology for big fusion machines.

Introduction. The process of oxygen conversion, despite the existing improvements, can be supplemented by physical methods of influence, including the unconventional method of applying low-voltage potential developed at the Iron and Steel Institute of the NAS of Ukraine.Problem Statement. The studies of the method of low-voltage potential application on 60, 160 and 250 ton converters have shown that the technology intensifies thermophysical and hydrodynamic processes in the gasslag-metal system and increases the converter process efficiency.Purpose. The purpose of this research is to study the features of the influence on the reaction zones of the low voltage potential application at four blowing options with the use of high-temperature physical model.Materials and Methods. A physical model that simulates the top, bottom and combined oxygen blowing under low-voltage potential application of different polarity on the lance has been used. An insert of a transparent quartz plate is made in one of the walls for visual observation and video recording. The top blowing is conductedwith two nozzle lance (nozzle diameter 1.7 mm with an angle of 30 ° to the lance). The bottom blowing is conducted with a bottom tuyere with a 1.5 mm diameter central nozzle. Combined blowing is realized by a combination ofthese options.Results. The visual observation of the reaction zones with different blowing options has shown that the highest temperature and the largest dimensions of the brightest parts of the bath correspond to the combined blowing, while the lowest ones are reported for the bottom blowing. While applying the low-voltage potential method it has been established that the reaction zone is longer at the positive polarity on the lance, during the period of silicon oxidation, and at the negative polarity on the lance, during the period of intense carbon oxidation. The video of gas bubbles flotation, probably CO, has shown that the bubbles are formed more intensively in thecase of negative polarity on the lance.Conclusions. The applied technique has allowed estimating the influence of low-voltage potential application on the geometric parameters of the reaction zone.
