Scientific school of doctor of biological sciences professor L.I. Rubtsov
No full textObjective – to explore the scientific school of the famous landscape architect, dendrologist, doctor of biological sciences professor Leonid Ivanovich Rubtsov.
Material and methods. Creative biographies of L.I. Rubtsov’s post graduate students have been analyzed. The historical- scientific method and method of interviews were used.
Results. The theoretical scientific developments of L.I. Rubtsov, set out in unique monographs, and his ideas are implemented practically during the construction a number of botanical gardens and parks were investigated. Professor Rubtsov worked fruitfully for 50 years in the field of dendrology and green building. In M.M. Gryshko National Botanical Garden of the NAS of Ukraine Leonid Ivanovich was the author and the head of the work on the arboretum creation. In 1972 the Botanical Garden was granted the status of a monument of landscape art of national importance. This became possible thanks to works of L.I. Rubtsov. His knowledge and great experience he passed on to his students, who eventually became good experts in dendrology and landscape architects. Professor L.I. Rubtsov was the head of 8 post graduate students (Candidates of Sciences): namely 3 Candidates of Architecture (I.D. Rodichkin, V.G. Maevskaya, V.I. Meshkova) and 5 Candidates of Biological Sciences (M.I. Orlov, Yu.K. Kirychek, M.F. Kaplunenko, B.K. Gryshko-Bogmenko, N.F. Kolybina).
Conclusions. Erudition, a wide range of interests and style of work of Leonid Ivanovich were of decisive importance for attracting young talents and for many years determined their creative ways. Scientific works of L.I. Rubtsov, especially monographs, reference books and manuals are still indispensable benefits for many specialists in the field of landscape architecture and decorative gardening
ИНДИВИДУАЛЬНАЯ ЧАСТОТА Α ОСЦИЛЛЯЦИЙ ЭЛЕКТРОЭНЦЕФАЛОГРАММЫ КАК НЕЙРОФИЗИОЛОГИЧЕСКИЙ ЭНДОФЕНОТИП ЭМОЦИОНАЛЬНЫХ ПРЕДИСПОЗИЦИЙ
No full textIndividual alpha frequency (IAF) of electroencephalogram (EEG) is regarded as a neurophysiological endophenotypic indicator of cognitive activity featuring individual propensity to efficient cognitive performance and creativity. Considering that cognitive coping style is intrinsic part of emotional regulation, defining medical aspects of individual health as well as risks of psychosomatic diseases, we intended to assess IAF contribution into mechanisms of individual emotional reactivity. Participants and methods. As participants was healthy man subjects (n=62). Three models of laboratory induced emotions were used: emotional perception (1); anxious apprehension (awaiting of inescapable aversive punishment) (2); experience of discrete emotions of anger and joy (3). Results. It was revealed that high IAF individuals exhibit predisposition to prevalence of parasympathetic activity in the global circuit of autonomous regulation, proactive-like coping with inescapable threat, prevailing contribution of the positive emotional stance and better accessibility of recent positive memories. By contrast, low IAF subjects manifested predisposition to prevalence of sympathetic activity in the global circuit of autonomous regulation, maladaptive avoidance-like coping with inescapable threat, insufficiency positive emotional arousal mechanisms. Conclusions. It is suggested that IAF creates a «hardware» construct featuring individual emotional space and adaptability of coping styles to emotional challenges. Индивидуальная частота α-ритма электроэнцефалограммы (individual alpha frequency, IAF) является важным нейрофизиологическим эндофенотипом, характеризующим предиспозицию к эффективной когнитивной деятельности. Учитывая, что когнитивные стратегии — важнейший компонент восприятия, переживания и регуляции эмоций, определяющий медицинские аспекты индивидуального здоровья и риски развития психосоматических заболеваний, цель настоящего исследования — оценить возможный вклад IAF в механизмы индивидуальной эмоциональной реактивности. Пациенты и методы. В качестве испытуемых выступали здоровые мужчины (n=62). Выполнено 3 психофизиологических исследования с различными моделями вызванных эмоций у человека: восприятия эмоций (1); переживания тревожного опасения (ожидания неизбегаемого аверсивного воздействия) (2); переживания дискретных положительных и отрицательных эмоций (3). Результаты. Установлено, что у лиц с высокой IAF наблюдается преобладание парасимпатических влияний в глобальном контуре вегетативной регуляции, проактивных копинг-стратегий совладания с неизбегаемой угрозой, преобладание активности положительной эмоциональной установки и доступность следов памяти на положительные переживания. Напротив, для индивидов с низкой IAF характерными являются преобладание симпатических влияний в глобальном контуре вегетативной регуляции, неадаптивные избегательные копинг-стратегии совладания со стрессором, недостаточность механизмов положительной эмоциональной активации. Выводы. Предполагается, что IAF создает устойчивый типологический контекст («hardware»), оказывающий модулирующее влияние на формирование индивидуального эмоционального пространства и адаптивность стратегий совладания с эмоциональными вызовами.

No full textAs a master student in AppliedMathematics at the Delft University of Technology I am highly educated in Numerical Analysis. My interest in this field even mademe choose elective courses such as Advanced Numerical Methods, Applied Finite Elements and Computational Fluid Dynamics. In my search for a challenging graduationproject I chose a research proposal on the material point method, an extension of the finite element method that is well-suited for problems involving large deformations. The proposal met al my personal requirements, since it contained a mathematical basis I am already familiar with and the opportunity to gain knowledge about a relatively new numerical method. Furthermore, it included an internship at DeltaresDelft Institute of Applied MathematicsElectrical Engineering, Mathematics and Computer Scienc

In-situ interfacial approaches on chemisorption and stability of buried metal oxide-polymer interfaces
No full textUntil today, interfacial bond formation and degradation between polymer coatings and metal substrates is still far from fully understood, whilst it is a limiting factor for the durability of metal-polymer hybrid systems. To improve the corrosion resistance and adhesion properties of metal substrates, a chemical surface treatment is applied prior to painting. However, due to ecological and health related issues, traditional well established surface treatments containing hexavalent chromate or high phosphate loads are being replaced by a new generation of ecologically-justified surface treatments. This comes with the need of gaining fundamental insights on the impact of substrate and pretreatment variations on the (chemical) adhesion of polymers to guarantee the lifetime of newly developed metal-polymer hybrid systems. A challenge in this regard is the hardly accessible buried interface, which until today requires the use of model systems when using non-destructive surface sensitive techniques. Yet, industrial metal-polymer hybrid systems are typically highly heterogeneous, creating a distinct gap between model and industrial systems. This dissertation aims to close this gap starting from simplified model systems to which complexity is gradually added. This has been done using the thin organic film approach on one hand, and the thin (thermally vaporized) metal substrate approach on the other hand, allowing non-destructive access of the metal-polymer interface from the polymer side and metal side, respectively. Complementary use of both approaches allows systematically comparison of model systems to industrially relevant paint and metal substrates.(OLD) MSE-
