Group Theoretical Description of the Periodic System
No full textThe group theoretical description of the periodic system of elements in the framework of the Rumer–Fet model is considered. We introduce the concept of a single quantum system, the generating core of which is an abstract C*-algebra. It is shown that various concrete implementations of the operator algebra depend on the structure of the generators of the fundamental symmetry group attached to the energy operator. In the case of the generators of the complex shell of a group algebra of a conformal group, the spectrum of states of a single quantum system is given in the framework of the basic representation of the Rumer–Fet group, which leads to a group-theoretic interpretation of the Mendeleev’s periodic system of elements. A mass formula is introduced that allows giving the termwise mass splitting for the main multiplet of the Rumer–Fet group. The masses of elements of the Seaborg table (eight-periodic extension of the Mendeleev table) are calculated starting from the atomic number Z=3 and going to Z=220. The continuation of the Seaborg homology between lanthanides and actinides is established with the group of superactinides. A 10-periodic extension of the periodic table is introduced in the framework of the group-theoretic approach. The multiplet structure of the extended table’s periods is considered in detail. It is shown that the period lengths of the system of elements are determined by the structure of the basic representation of the Rumer–Fet group. The theoretical masses of the elements of 10th and 11th periods are calculated starting from Z=221 and going to to Z=364. The concept of hypertwistor is introduced
Análise qualitativa dos custos decorrentes da personalização de unidades habitacionais
No full textDissertação (mestrado) - Universidade Federal de Santa catarina, Centro Tecnológico. Programa de Pós-graduação em Engenharia Civil.A personalização de unidades habitacionais vem sendo oferecida pelas empresas construtoras como forma de proporcionar um diferencial ao produto. No entanto, devido à complexidade deste tipo de obra, há dificuldades para se calcular o custo real decorrente do oferecimento de unidades personalizadas. Sendo assim, o presente trabalho teve como objetivo realizar uma análise em termos qualitativos dos fatores que podem interferir nos custos de empreendimentos personalizados. Para tanto, foram feitos sete estudos de caso englobando as cidades de Florianópolis, Maceió, Rio de Janeiro e Fortaleza visando analisar em conjunto as informações referentes às características da empresa construtora, do empreendimento executado, do tipo de personalização oferecida e do processo administrativo adotado pela empresa na execução deste empreendimento. De posse destas informações, foram realizadas as seguintes análises: do processo de vendas, das escolhas dos clientes frente às opções de planta oferecidas, do processo de planejamento e controle adotado e dos principais problemas ocasionados pela personalização. Verificou-se que outros fatores, como a localização e as condições de pagamento, tiveram maior impacto sobre as vendas do que a personalização propriamente dita. Além disso, as empresas estudadas apresentaram posturas diferentes no que diz respeito ao atendimento às solicitações de mudanças pelos clientes após o término do prazo permitido. O processo de planejamento e controle se mostrou essencial na execução de empreendimentos deste tipo, sendo também adotadas medidas para aumentar a transparência do processo. Os principais problemas relacionados à personalização dependem da postura adotada pelas empresas, bem como do nível organizacional das mesmas

No full textIn the article the author made an analysis of heritage of famous Ukrainian artists, public figures and educators, pedagogues and psychologists musicians of eighteenth and twentieth century, different issues concerning the impact of music and music education on the child's personality; organization of musical education in preschool institutions. Formation and development of a national system of preschool music education in Ukraine related to activities and views on music education of famous Ukrainian artists of XVIII-XIX centuries, namely Skovoroda and Shevchenko.
The issue of implementation of different kinds of music in kindergartens at the state level has been discussed since the mid-nineteenth century.Artistic, educational and developmental potential of music in training and education of preschool children was recognized. This process was greatly influenced by Soviet public figures and teachers of the nineteenth and twentieth centuries (V. Odoyevskyy, S. Rusova, M. Sventytska, A. Simonovic, E. Tyhyeyeva, K. Ushinsky).
Ukrainian musicians and educators of the nineteenth and twentieth centuries (V. Verhovinets, M. Lysenko, J. Steppe, K. Stetsenko, D. Leontovych, B. Jaworski et al.) made significant contribution to developing the national musical education of preschool children, musical development and publication of manuals.
The development of theoretical and methodological principles on the national level introduced in the early and mid-twentieth century influenced preschool musical education, as well as musical-rhythmic system of education (N. Alexandrova, N. Rumer, B. Hryner, A. Konorovoyi) and music education (N. Vyetluhinoyi, D. Kabalevskoho, M. Palavandishvili, O. Radynovoyi, M. Rumer, V. Shatskoyi, S. Sholomovych etc.), who studied development of children’s musical perception, psychological and pedagogical means of influence and conditions of the basics of musical culture, contents, methods and forms of musical development, education of preschool children and more.
A significant impact on design and development of the concept of musical education of preschool children was made by psychologists (L. Vygotsky, V. Romenets, S. Naumenko, K. Tarasova). They noted that the objectives of musical education of young children is forming their aesthetic attitude to music and musical activities.У статті автором зроблений аналіз спадщини відомих українських митців, громадських діячів і педагогів, педагогів-музикантів і психологів ХVІІІ-ХХ сторіччя, які переймалися проблемою різнобічного впливу музики, музичного виховання на особистість дитини, організацією музичного виховання у дошкільних закладах.
Становлення та розвиток національної системи дошкільного музичного виховання в Україні пов’язано з діяльністю та поглядами на музичне виховання відомих українських митців ХVІІІ-ХІХ ст. Г. Сковороди та Т. Шевченка. З середини ХІХ ст. відбувається обговорення на державному рівні питання впровадження різних видів музичної діяльності у дошкільні заклади і визнається необхідність урахування художньо-виховного та розвивального потенціалу музики у процесі навчання і виховання дітей дошкільного віку.
У розвиток національної системи музичного виховання дітей дошкільного віку вагомий внесок зробили радянські громадські діячі і педагоги ХІХ-ХХ ст. (В. Одоєвський, С. Русова, М. Свентицька, А. Симонович, Є. Тихєєва, К. Ушинський), українські педагоги-музиканти (В. Верховинець, М. Лисенко, Я. Степовий, К. Стеценко, Д. Леонтович, Б. Яворський та ін. ).
На розвиток теоретико-методичних засад національного дошкільного музичного виховання вплинули впроваджені на початку та в середині ХХ ст. системи музично-ритмічного виховання Н. Александрової, Н. Румер, В. Гринер, А. Конорової та музичного виховання Н. Вєтлугіної, Д. Кабалевського, М. Палавандішвілі, О. Радинової, М. Румер, В. Шацької, С. Шоломович та ін. Важливу роль у справі розробки та розвитку концепції музичного виховання дітей дошкільного віку здійснені психологами Л. Виготським, В. Роменець, С. Науменко, К. Тарасової, Б. Тепловим.
Наведений матеріал структурований у хронологічному порядку, що дозволяє простежити часовий проміжок у розвитку національної системи дошкільного музичного виховання в Україні

Piezoelectric-Layered Structures Based on Synthetic Diamond
No full textТекст статьи не публикуется в открытом доступе в соответствии с политикой журнала.Results of theoretical, modeling, and experimental investigation of microwave acoustic
properties of piezoelectric layered structure “Me1/AlN/Me2/(100) diamond” have been
presented within a wide frequency band 0.5–10 GHz. The highest among known
material quality parameter Q × f ~ 10^14 Hz for the IIa type synthetic diamond at
operational frequency ~10 GHz has been found. Conditions of UHF excitation and
propagation of the bulk, surface, and Lamb plate acoustic waves have been established
and studied experimentally. Frequency dependencies of the impedance and quality
factor have been studied to obtain a number of piezoelectric layered structure
parameters as electromechanical coupling coefficient, equivalent circuit parameters, etc.
Results of 2D finite element modeling of a given piezoelectric layered structure have
been compared with the experimental ones obtained for the real high-overtone bulk
acoustic resonator. An origin of high-overtone bulk acoustic resonator’s spurious
resonant peaks has been studied. Results on UHF acoustic attenuation of IIa-type
synthetic single crystalline diamond have been presented and discussed in terms of
Akhiezer and Landau–Rumer mechanisms of phonon–phonon interaction. Identification
and classification of Lamb waves belonging to several branches as well as dispersive
curves of phase velocities have been executed. Necessity of introducing a more correct
Lamb-mode classification has been recognized

КТ-семиотика травматических и нетравматических повреждений селезенки
No full textPurpose. To demonstrate capabilities and features in spleen pathology diagnostics based on clinical experience of Botkin City Hospital.Materials and methods. The analysis of 89 patients with spleen abnormalities was performed in the term from 01/2014 till 08/2020. All the patients underwent computed tomography (CT) and/or magnetic resonance imaging (MRI) with contrast enhancing. All cases verified surgically and/or clinically.Results. There were 37 cases of trauma (42%). Accuracy and precision of the method was 100%. In detection of active bleeding the highest diagnostic accuracy (100%) was shown with extravasation symptom – 7 cases. In non-traumatic group (n = 52, 58%) two biggest sub-groups were abscesses (n = 19, 36% in this group) and infarctions (n = 15, 29%). There were 8 cases of cysts (15%), 3 of them – hydatid, 5 cases of spleen hemangiomas. (9.6%), 3 cases of spleen metastases (6%). There was 1 case of angiosarcoma (2%) and 1 case cystic lymphangioma (2%).Conclusion. The most frequent condition in spleen pathology, diagnosed in radiology department is trauma. In non-traumatic cases two biggest groups are abscesses and infarctions. CT features of spleen infarction are pyramidal wedge of hypoperfused splenic tissue with the apex pointing towards the hilum, and the base on the splenic capsule. In all cases in our study cysts were incidental findings. Spleen metastases are rare due to organ hemodynamics. The most rare lesions of the spleen are primal tumors.Цель исследования: продемонстрировать различные аспекты диагностики патологических изменений селезенки, выявляемых при компьютерной томографии (КТ), проанализировать частоту их встречаемости и значимость в клинической практике.Материал и методы. Проанализированы данные 89 пациентов, обследованных на базе ГКБ имени С.П. Боткина в период с 01.2014 по 08.2020, с выявленными патологическими изменениями селезенки. Всем пациентам выполнялась КТ и 25 – магнитно-резонансная томография (МРТ) с контрастированием. Исследования с контрастированием проводились по трехфазной программе сканирования с выделением артериальной, паренхиматозной и отсроченной фаз. Все включенные в работу случаи верифицированы клинически и/или интраоперационно.Результаты. Выявлено 37 (42%) случаев травматических повреждений. Диагностическая точность составила 100%. Абсолютную точность в выявлении активного кровотечения демонстрировал симптом экстравазации – 7 наблюдений. Из 52 (58%) случаев нетравматических изменений наиболее часто выявлялись абсцессы (n = 19, 36%) и инфаркты (n = 15, 29%). Из 8 (15%) наблюдений кист 3 являлись паразитарными. Имелось 5 (9,6%) наблюдений гемангиом, 3 (6%) случая метастатического поражения. В 1 (2%) случае выявлена ангиосаркома и в 1 (2%) – кистозная лимфангиома.Обсуждение. Наиболее часто выявляются травматические повреждения селезенки. В группе нетравматических изменений чаще встречаются абсцессы и инфаркты. Кисты чаще являются случайными находками, в том числе паразитарные. Опухолевое поражение, как первичное, так и вторичное, встречается крайне редко.Заключение. КТ помогает решить большую часть задач, предъявляемых в вопросах диагностики заболеваний селезенки. Необходимо знать характерные черты патологических состояний и уметь обращать на них внимание
