A Model for the Sustainable Management of Enterprise Capital
Authors: Klimek Dariusz , Jędrych Elżbieta
Published: December 2020

This paper attempts to develop the concept of sustainable management of enterprise capital presented, e.g., in Economies at the beginning of the year 2020. After an introduction and presentation of the theoretical grounds for the construction of the model, the authors attempt at describing its characteristics in a few points, determining the relationship between the objectives of an enterprise and the capitals that constitute the elements of that enterprise. The main assumption in the model is that the management of an enterprise is a constant process of striving to achieve a goal or goals, and balancing the level of the capitals within the enterprise. The point of balance between six capitals of an enterprise entails, at the same time, the maximum effectiveness of this enterprise. The more effective an enterprise, the quicker the managers will reach the point of balance between the capitals, and the longer the managers will maintain the values of the capitals near the balance point. As a measure of effectiveness, the authors propose a coefficient of a mean percentage-rated difference between the capitals, which reflects the mean non-adjustment of the capitals, and the weighed capital differences coefficient, which reflects the effectiveness of an enterprise as a whole. In the second part, the authors prove that, simultaneously, both management based on the presented model, which is based on the effectiveness of achieving objectives, as well as the effectiveness of the capitals of the enterprise, with the use of the new economic ratios as indicated, may be an alternative to globally prevalent revenue as an economic measurement.
Predictive Model for Amotivation and Discipline in Physical Education Students Based on Teaching–Learning Styles
Authors: Leyton-Román Marta , González-Vélez Jaime José León , Batista Marco , Jiménez-Castuera Ruth
Published: December 2020

One of the purposes of teachers is to ensure the motivation of the students in their classes and to maintain disciplined behaviours. However, the teaching styles and methodologies used do not always have a positive effect on student’s motivation and discipline. This study analysed the relationship between student’s perceptions of the controlling behaviours of their physical education teacher, together with amotivation and discipline styles from Self-Determination Theory. The sample comprised 922 students, aged between 14 and 18 years (M = 14.95; SD = 0.98). Students’ perceptions of less controlling discipline styles (control of the use of rewards) negatively predicted the thwarting of autonomy need. Conversely, a more controlling discipline style (judging and devaluing) positively predicted the thwarting of autonomy need, and this, positively predicted amotivation, which negatively predicted disciplinary behaviours and positively predicted undisciplined behaviours. Teachers must avoid using controlling behaviours like judging and devaluing, as this reinforces amotivation towards physical education and undisciplined student behaviours. The importance of designing classes where the student has responsibilities to make decisions and to be part of their own learning is pointed out.
Living Labs—A Concept for Co-Designing Nature-Based Solutions
Authors: Lupp Gerd , Zingraff-Hamed Aude , Huang Josh J. , Oen Amy , Pauleit Stephan
Published: December 2020

Living Labs are recognized as a progressive form to foster innovation and the strengthening of collaborative planning. The concept has received strong attention by the European Union (EU) research and innovation agendas recently. This contribution investigates how a Living Lab approach could be used for the design and implementation of Nature-Based Solutions (NBS). NBS are gaining acceptance as a more sustainable solution for reducing the exposure to natural hazards and vulnerability to events, such as increased flooding in changing climate. However, a lack of collaborative approaches hinders their broader implementation. A literature review on the theoretical aspects of the Living Labs concept in the context of NBS is conducted, and we compare the theoretical findings with practices that were observed by case studies implementing NBS in a collaborative manner. The Isar-Plan River Restoration in Munich, Germany, and the Mountain Forest Initiative (Bergwaldoffensive). Both of the case studies have already started well before the concept of Living Labs gained wider popularity. Both award-winning cases are recognized good practice for their exemplary in-depth stakeholder involvement. The paper discusses the concepts and approaches of Living Labs and reflects on how it can serve and support in-depth participatory stakeholder involvement.

Severe fever with thrombocytopenia syndrome (SFTS) is caused by SFTS virus (SFTSV). We investigated the detailed kinetics of serologic response in patients with SFTS. Twenty-eight patients aged ≥18 years were enrolled between July 2015 and October 2018. SFTS was confirmed by detecting SFTSV RNA in their plasma using reverse transcription polymerase chain reaction. SFTSV-specific IgG and IgM were measured using immunofluorescence assay (IFA) and enzyme-linked immunosorbent assay (ELISA). We found that SFTSV-specific IgG was detected at days 5–9 after symptom onset, and its titer was rising during the course of disease. SFTSV-specific IgM titer peaked at around week 2–3 from symptom onset. The SFTSV-specific seropositive rates for days 5–9, 10–14, 15–19, and 20–24 from symptom onset using IFA and ELISA were 63%, 76%, 90%, and 100%, and 58%, 86%, 100%, and 100%, respectively, for IgG, whereas they were 32%, 62%, 80%, and 100%, and 53%, 62%, 70%, and 100%, respectively, for IgM. The delayed IgM response could be attributed to the low sensitivity of SFTSV-specific IgM IFA or ELISA and/or impaired immune responses. The IgM test using IFA or ELISA that we used in this study is, therefore, insufficient for the early diagnosis of SFTS.
Endothelium Infection and Dysregulation by SARS-CoV-2: Evidence and Caveats in COVID-19
Authors: Bernard Isabelle , Limonta Daniel , Mahal Lara , Hobman Tom
Published: December 2020

The ongoing pandemic of coronavirus disease 2019 (COVID-19) caused by the acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) poses a persistent threat to global public health. Although primarily a respiratory illness, extrapulmonary manifestations of COVID-19 include gastrointestinal, cardiovascular, renal and neurological diseases. Recent studies suggest that dysfunction of the endothelium during COVID-19 may exacerbate these deleterious events by inciting inflammatory and microvascular thrombotic processes. Although controversial, there is evidence that SARS-CoV-2 may infect endothelial cells by binding to the angiotensin-converting enzyme 2 (ACE2) cellular receptor using the viral Spike protein. In this review, we explore current insights into the relationship between SARS-CoV-2 infection, endothelial dysfunction due to ACE2 downregulation, and deleterious pulmonary and extra-pulmonary immunothrombotic complications in severe COVID-19. We also discuss preclinical and clinical development of therapeutic agents targeting SARS-CoV-2-mediated endothelial dysfunction. Finally, we present evidence of SARS-CoV-2 replication in primary human lung and cardiac microvascular endothelial cells. Accordingly, in striving to understand the parameters that lead to severe disease in COVID-19 patients, it is important to consider how direct infection of endothelial cells by SARS-CoV-2 may contribute to this process.
Review: Sources of Hydrological Model Uncertainties and Advances in Their Analysis
Authors: Moges Edom , Demissie Yonas , Larsen Laurel , Yassin Fuad
Published: December 2020

Despite progresses in representing different processes, hydrological models remain uncertain. Their uncertainty stems from input and calibration data, model structure, and parameters. In characterizing these sources, their causes, interactions and different uncertainty analysis (UA) methods are reviewed. The commonly used UA methods are categorized into six broad classes: (i) Monte Carlo analysis, (ii) Bayesian statistics, (iii) multi-objective analysis, (iv) least-squares-based inverse modeling, (v) response-surface-based techniques, and (vi) multi-modeling analysis. For each source of uncertainty, the status-quo and applications of these methods are critiqued in gauged catchments where UA is common and in ungauged catchments where both UA and its review are lacking. Compared to parameter uncertainty, UA application for structural uncertainty is limited while input and calibration data uncertainties are mostly unaccounted. Further research is needed to improve the computational efficiency of UA, disentangle and propagate the different sources of uncertainty, improve UA applications to environmental changes and coupled human–natural-hydrologic systems, and ease UA’s applications for practitioners.
Estimation of Hourly Flood Hydrograph from Daily Flows Using Artificial Neural Network and Flow Disaggregation Technique
Authors: Lee Jeongwoo , Lee Jeong Eun , Kim Nam Won
Published: December 2020

Flood data on a high temporal scale are required for the design of hydraulic structures, flood risk assessment, flood protection, and reservoir operations. Such flood data are typically generated using rainfall-runoff models through an accurate calibration process. The data also can be estimated using a simple relationship between the daily and the sub-daily flow records as an alternative to rainfall–runoff modelling. In this study, we propose an approach combining an artificial neural network (ANN) model for peak flow estimation and the steepness index unit volume flood hydrograph (SIUVFH) method for sub-daily flow disaggregation to generate hydrographs on an hourly time scale. The SIUVFH method is based on the strong relationship between the flood peak and the steepness index, which is defined as the difference between the daily flood peak and daily flow several days before the peak; it is also used for selecting a reference unit volume flood hydrograph to be scaled to obtain the sub-daily flood hydrograph. In this study, to improve the applicability of the SIUVFH method for locations with a weak relationship between the flood peak and steepness index, the ANN-based flood peak estimation was used as an additional indicator to determine a reference unit volume flood hydrograph. To apply the proposed method, ANN models for estimating the peak flows from the mean daily flows during peak and adjacent days were constructed for the studied dam sites. The optimal ANN structures were determined through Monte Carlo cross-validation. The results showed a good performance with statistical measurements of relative root mean square errors of 0.155–0.224, 0.208–0.301, and 0.244–0.382 for the training, validation, and testing datasets, respectively. An application of the combined use of the ANN-based peak estimation and the SIUVFH-based flow disaggregation revealed that the disaggregated hourly flows satisfactorily matched the observed flood hydrograph.

The use of grey alder Alnus incana by foraging Black Woodpeckers Dryocopus martius during winter
Authors: Olsson Christer
Published: December 2020

Very few studies have been made on the Black Woodpecker’s Dryocopus martius feeding on deciduous trees in Scandinavia, especially at winter. This pilot study on the Black Woodpecker’s feeding in grey alder Alnus incana showed that the grey alder is a significant feeding tree during the winter months. The woodpeckers seem to prefer feeding in the southerly sector of grey alder trunks with a diameter of 13.5–15.4 centimetres, in their first dying stages. This study indicates that litter of a significant size, that is found beneath trees penetrated by woodpeckers, are from carvings made by the Black Woodpecker. Litter surveying may hence be an alternative investigational method to radio tracking for nutritional studies on the Black Woodpecker. This paper also discusses the role of a potential prey found in grey alders, the alder wood-wasp Xiphydria camelus, as a complementary food source at winter in different parts of Sweden, compared to the more well-described carpenter ants Camponotus herculeanus found in Norway spruce Picea abies.
Entre Lacan y Benjamin: la segunda muerte como asunto de la redención. Pervivencia [Nachleben] y experiencia histórica
Authors: Fuks Ludmila
Published: December 2020

En la tesis VI de Sobre el concepto de historia (1940) de Walter Benjamin  nos encontramos con la sentencia de peligro en que se encuentran los muertos, que podemos pensar como amenaza de una segunda muerte,  o muerte simbólica de la tradición oprimida de la cual el historiógrafo tiene que estar alerta. Ahora bien, si hay una segunda muerte es porque hay una vida después de la muerte natural, es decir una pervivencia [Nachleben] del pasado en el presente. Esta pervivencia, en el contexto de las tesis de 1940, es posible hilarla con las nociones de experiencia [Erfahrung] histórica y la transmisión de la misma. Frente al peligro de desaparición absoluta de aquello que ha quedado trunco, el autor alemán expone la necesariedad de salvarlo, es decir de realizar una redención, una rememoración. En este sentido, la redención operaría como segunda chance, o segunda instancia, de aquellos que ya han tenido una muerte natural, y que por tanto perviven, se encuentran en su “sobre-vida”, que se encuentra al borde de desaparecer. La redención, en estos términos, se reconfigura como una forma de resistencia, entonces, frente al posible aniquilamiento que enterraría definitivamente aquellos significantes, aquellas memorias. El ensayo que aquí llevaremos a cabo será pensar los posibles cruces entre las nociones benjaminianas de pervivencia, experiencia histórica y redención, y la noción lacaniana de segunda muerte, para así pensar entre ambos autores la dualidad de la muerte y la vida en tanto natural y simbólica (o espectral), lo fallado de la muerte natural –las remanencias y posibilidades de redención que deja- y lo absoluto e irreversible de la segunda muerte.

Mapeando el (des)orden espacial: cartografía social en Cabure-í, Misiones "
Authors: Fernández Romero Francisco , Muñecas Lucila , Zanotti Aymara Suyai , Piccinali Luis
Published: December 2020

Nuestro objetivo central en este artículo es reflexionar sobre los aportes que puede realizar la cartografía social para identificar la espacialidad, o los aspectos específicamente espaciales, de los procesos sociales. Para ello, analizamos un mapeo realizado en Cabure-í, Misiones, junto con una cooperativa de pequeños productores. Este mapeo apuntaba a poner de relieve, para quienes integran la cooperativa, la dimensión espacial de la situación actual respecto a la tenencia de la tierra, lo cual contribuiría a re-enmarcar la precariedad en dicha tenencia no ya como un problema de familias particulares, sino como una problemática de escala colectiva. Pero, además, para nuestro grupo de investigación, esta actividad de cartografía social nos llevó a cuestionar nuestros propios supuestos en torno al orden espacial configurado por las y los integrantes de la cooperativa. Mientras que suponíamos que las divisiones catastrales oficiales sólo tendrían relevancia para la cotidianeidad de la población dado que legitiman órdenes de desalojo en su contra –casi ninguna familia es propietaria de la tierra–, hallamos que el mapa catastral, además, ha sido reapropiado por la población para la propia delimitación de sus chacras.

Espaços públicos e territórios. As relações entre espaço e poder na Geografia
Authors: Da Costa Gomes Paulo Cesar
Published: December 2020

O artigo discute a tendência do uso exclusivo do conceito de território, entre os geógrafos, na análise das relações entre espaço e poder. Conceitos são instrumentos que orientam e delimitam as análises. No caso do conceito de território, as dinâmicas geradas pelos conflitos entre distintos grupos sociais e os mecanismos de apropriação espacial são elementos estruturantes. A despeito disso, há outras formas de análise que não demandam a caracterização de grupos sociais tão distintos e autônomos e focalizam processos de outra natureza, diferentes da simples apropriação do espaço. O conceito de espaço público, por exemplo, faz emergir outros elementos essenciais à discussão sobre espaço e poder, tais como o da convivência entre diferentes indivíduos que compartem um mesmo espaço e, para isso, estabelecem regulações. Todos os problemas e desafios dessa engenharia social e sua espacialidade permanecem pouco conhecidos e estudados, em parte, pela sobrevalorização da consideração territorial.

Abstract: The Book of Ruth is one of the Old Testament books that is classified as a book of history.  The story in the book of Ruth took place during the reign of the judges. The time when the apostasy of the nation of Israel was so apparent. The time when the Israelites began to worship idols. A time when there was competition among the tribes of Israel. The book of Ruth begins with famine in the land of Israel, which brought the family of Elimelech from Bethlehem-Judah to migrate to the land of Moab and settled there. The story continues with a sad story. Naomi's husband and even her two children died in the land of Moab. The series of stories left the impression that there was no presence of God in the midst of the Naomi family. Resulting in two widows who finally struggled to survive. Through literature study, two main points from the series of stories are revealed. First, even though God seems invisible, but behind everything God does not stop nurturing. God is present in silence. God works through the lives of faithful people. Second, despite the various crises that hit the country, even though evil and sin continue to be made by humans, even though it is as if God left humanity. But truly God is still the Alpha and Omega, who will not leave the deeds of his hands but always and always work in the midst of humanity who hope, loyal, and surrender to Him.
 
Keywords: Naomi, Ruth, Nurturing, Loyalty, God
 
Abstrak-Kitab Rut merupakan salah-satu dari Kitab Perjanjian Lama yang tergolong sebagai kitab sejarah. Kisah dalam kitab Rut terjadi pada zaman pemerintahan hakim-hakim. Masa di mana kemurtadan bangsa Israel begitu nampak. Masa di mana bangsa Israel mulai menyembah berhala. Masa di mana terjadi persaingan di antara suku Israel. Kitab Rut di awali dengan kelaparan di tanah Israel, yang membawa keluarga Elimelekh dari Betlehem-Yehuda merantau ke tanah Moab dan menetap di sana. Kisahnya terus berlanjut dengan kisah yang menyedihkan. Suami Naomi bahkan kedua anaknya meninggal di tanah Moab. Rentetan kisahnya meninggalkan kesan tiada kehadiran Allah di tengah-tengah keluarga Naomi. Mengakibatkan dua orang janda yang akhirnya berjuang untuk dapat bertahan hidup. Melalui studi kepustakaan tersingkap dua hal pokok dari rentetan kisah tersebut. Pertama, sekalipun Allah seolah-olah tidak nampak namun di balik semuanya Allah tidak berhenti memelihara. Allah hadir dalam kesenyapan. Allah berkarya melalui hidup orang yang setia. Kedua,  Meskipun berbagai krisis melanda negeri, meskipun kejahatan dan dosa terus diperbuat manusia, meskipun seakan-akan Allah meninggalkan umat manusia. Namun sungguh Allah tetaplah Alfa dan Omega, yang tidak akan meninggalkan perbuatan tangannya melainkan selalu dan senantiasa berkarya di tengah-tengah umat manusia yang berharap, setia, dan berserah  kepada-Nya.

financiamiento climático internacional y los desafíos de su catalización. Debates sobre la brecha entre necesidades climáticas y financiamiento, de Bali (2007) a París (2015)
Authors: Brussa María Elisa
Published: December 2020

El cambio climático es uno de los grandes desafíos de la agenda global. Para resolver estas cuestiones, desde el Plan de Acción de Bali en 2007 se ha consolidado a nivel global una arquitectura internacional de financiamiento climático altamente compleja, multi-institucional y multi-escalar. Aunque el sistema funciona en muchos casos, varios aspectos obstaculizan la capacidad de catalizar el volumen completo de recursos, así como la implementación eficiente del financiamiento para lograr cambios transformacionales importantes, particularmente en aquellas “áreas difíciles de mitigar”. Se sostiene así que el marco de un régimen policéntrico de la gobernanza financiera ambiental y de excesiva fragmentación organizacional e institucional del esquema de financiamiento de recursos climáticos, implica múltiples exigencias a nivel país que no necesariamente redundan en una asignación eficaz de las respuestas financieras al deterioro climático. Para este trabajo se utilizó un método cualitativo. Para ello se recolectaron datos a través de la revisión bibliográfica de documentos y trabajos de investigación disponibles en organismos multilaterales de crédito y de organismos especializados de la cooperación ambiental internacional. Dichos datos fueron analizados mediante un análisis temático. Con este trabajo, se pretende contribuir a las discusiones sobre cooperación internacional climática.

Objetivo. La inmunización es una de las intervenciones más importantes para prevenir la morbimortalidad en la población mundial. No obstante, aún persisten brechas para alcanzar coberturas ideales de vacunación. Además, las múltiples dosis y vacunas dificultan alcanzar las metas mínimas establecidas. Por ello, se desarrollan vacunas combinadas y fraccionadas para reducir el número de inyecciones, errores programáticos, reactogenicidad y mejorar la adherencia. En tres días distintos, durante 9 horas, se reunieron 6 médicos pediatras expertos en vacunas en el Perú siguiendo el método RAND/UCLA, con el objeto de elaborar un consenso de opinión y actualización de la vacuna combinada hexavalente [DTaP+Haemophilus influenzae tipo b (Hib)+Hepatitis B (HVB)+antipolio inactivada (IPV)] y su eventual uso en el Programa ampliado de inmunizaciones (PAI). Las recomendaciones del consenso son: reemplazar las vacunas, antipolio oral (OPV) por IPV, pertussis de células enteras por vacunas acelulares y DTP de los 4 años por dTap entre los 4 y 6 años; usar la vacuna hexavalente para la serie primaria (2, 4 y 6 meses); usar 4 dosis de vacuna contra Hib (2, 4, 6 y 18 meses); incorporar la vacuna hexavalente en el PAI; no usar la IPV fraccionada (fIPV) y administrar solo 4 dosis de IPV.

Analysis of breast cancer whole-slide image is an extremely labor-intensive process. Histological whole slide images have the following features: a high degree of tissue diversity both in one image and between different images, hierarchy, a large amount of graphic information and different artifacts. In this work, pre-processing of breast cancer whole-slide tissue image was carried out, which included normalization of the color distribution and the image area selection. We reduced the operating time of the other algorithms and excluded areas of breast cancer whole-slide tissue with a background to analyze. Also, an algorithm for finding similar neoplastic regions for semi-automatic selection using various image descriptors has been developed and implemented.

Retinal detachment in children often requires multiple revisions. Despite active surgical treatment, subretinal fluid can persist for a long time in the macular region of the fundus. This leads to a decrease in visual acuity after surgery and an unsatisfactory functional result of treatment. In the absence of central vision, children develop amblyopia and secondary strabismus. Reoperations increase the risk of complications. Threshold laser coagulation leads to thermal burns of all layers of the retina with the formation of chorioretinal adhesion, which ensures adhesion of the retinal layers, but irreversibly damages the retinal neuroepithelium. Аs a result, the use of threshold laser coagulation in the macular zone is limited. The method of subthreshold micropulse diode laser ablation (STDLA) was developed on the basis of a clinical examination of 44 pediatric patients of the pediatric ophthalmology department of the Minsk Regional Children's Clinical Hospital, whose level of subretinal fluid in the posterior pole of the eyes remained for a long time after extrascleral surgery for retinal detachment. The proposed exposure parameters provide a selective effect on the cells of the retinal pigment epithelium with laser radiation in the micropulse mode without irreversible thermal denaturation of photoreceptors and without damage to the neuroepithelium in order to stimulate the resorption of subretinal fluid and correct transudative disorders. As a result, the adhesion of the retinal photoreceptor layer to the pigment epithelium is restored. The effectiveness of the method is confirmed by a decrease or complete disappearance of subretinal fluid, adhesion of neuroepithelium according to optical coherence tomography and leads to an increase in visual acuity. The proposed method made it possible to optimize the treatment of children with retinal detachment, to improve the anatomical and functional outcomes of treatment, which is of medical and socio-economic importance.

Published: December 2020

We propose the modeling of electron transport in GaN-based high electron mobility transistors (HEMTs) by combining the Poisson–Schrodinger method and the cellular automaton method. In HEMT, it is necessary to consider the influence of two-dimensional electron gas, band nonparabolicity, and upper valley on drift velocity. A wide range of electron transport modeling environments from low to high electric fields is required. By using the cellular automaton method instead of the traditional Monte Carlo carrier transport modeling method, noise-free drift velocity analysis is realized even at low electric fields. This makes it possible to stably investigate the effects of the HEMT structure and the influence of various scattering mechanisms on the drift velocity.

The recent outbreak of a novel coronavirus (SARS-CoV-2) has caused substantial public health issues worldwide. Cold atmospheric plasma (CAP) has shown its potential application in sterilization. It would be interesting to check the possible effect of CAP on the structure of the C-terminal domain of SARS-CoV-2 (SARS-CoV-2-CTD) spike protein and the interaction SARS-CoV-2-CTD with human angiotensin-converting enzyme 2 (hACE2). Therefore, we performed molecular dynamics simulations to calculate the root-mean-square deviation, root-mean-square fluctuation, principal component analysis and solvent-accessible surface area of SARS-CoV-2-CTD and the SARS-CoV-2-CTD/hACE2 complex with and without possible oxidation.

Ефективний і безпечний спосіб зберігання водню - це його хімічне зв'язування в металогідридах. Незважаючи на те, що вчені приділяють велику увагу гідриду магнію, він ще не знайшов широке застосування в якості акумулятора водню для автомобільної промисловості через високу температуру (300 °C при 0,1 МПа H2) і повільну кінетику дисоціації. У даній роботі досліджена можливість зниження температури, поліпшення кінетики розкладу стехіометричного гідриду MgH2 за рахунок його комплексного легування Fe і Y з застосуванням методу реактивного механохімічного сплавлення (РМС). Були синтезовані механічні сплави Mg + 10% ваг. Fe + 5% ваг. Y (МС1) і Mg + 10% ваг. Fe (МС2) і досліджено їх фазовий склад, мікроструктуру, водородосорбційні властивості, термічну стабільність і кінетику десорбції водню з використанням методів рентгенівської дифракції (XRD), скануючої електронної мікроскопії (SEM) і термодесорбційної спектроскопії (TDS). Для оцінки впливу комплексного легування на температуру розкладу і термостабільність фази MgH2 отримані ізобари десорбції водню при першому нагріванні після синтезу РМС зразків механічних сплавів і після подальшого їх циклічного гідрування з газової фази. Всі ізобари отримані при тиску водню в реакторі 0,1 МПа і швидкості нагріву зразка 30/ хв. і використані для визначення як температури початку десорбції водню (Тпоч.) з гідридної фази MgH2 МС, так і температури Тмакс., що відповідає максимальній швидкості виділення водню. Кінетичні криві десорбції водню з механічних сплавів-композитів отримані при постійному тиску водню 0,1 МПа в реакторі і температурах 310 і 330 °С і були використані для визначення як часу виділення половини кількості водню (τ1/2), так і загальної кількості виходу водню (τп) з МС. Встановлено, що додавання Fe і Y до магнію призводить до значного поліпшення кінетики десорбції водню з гидридної фази MgH2, про що свідчить значне зменшення (в 15 і 6 разів) часу виділення з неї половини і всього водню при 330 0С. Розроблені матеріали можуть знайти практичне використання в стаціонарних умовах їх застосування.Бібл. 48, табл.2, рис. 9.
