Standard Thermodynamic Functions of Tripeptides N-Formyl-L-Methionyl-L-Leucyl-L-Phenylalaninol and N-Formyl-L-Methionyl-L-Leucyl-L-Phenylalanine Methyl Ester

The heat capacities of tripeptides N-formyl-l-methionyl-l-leucyl-l-phenylalaninol (N-f-MLF-OH) and N-formyl-l-methionyl-l-leucyl-l-phenylalanine methyl ester (N-f-MLF-OMe) were measured by precision adiabatic vacuum calorimetry over the temperature range from T = (6 to 350) K. The tripeptides were stable over this temperature range, and no phase change, transformation, association, or thermal decomposition was observed. The standard thermodynamic functions: molar heat capacity C[subscript p,m], enthalpy H(T) – H(0), entropy S(T), and Gibbs energy G(T) – H(0) of peptides were calculated over the range from T = (0 to 350) K. The low-temperature (T ≤ 50 K) heat capacities dependencies were analyzed using the Debye’s and the multifractal theories. The standard entropies of formation of peptides at T = 298.15 K were calculated.National Institute for Biomedical Imaging and Bioengineering (U.S.) (Grant EB-003151)National Institute for Biomedical Imaging and Bioengineering (U.S.) (Grant EB-001960)National Institute for Biomedical Imaging and Bioengineering (U.S.) (Grant EB-002026)Ministry of Education and Science of the Russian Federation (Contract 14.B37.21.0799

Low-Temperature Polymorphic Phase Transition in a Crystalline Tripeptide L-Ala-L-Pro-Gly·H2O Revealed by Adiabatic Calorimetry

We demonstrate application of precise adiabatic vacuum calorimetry to observation of phase transition in the tripeptide l-alanyl-l-prolyl-glycine monohydrate (APG) from 6 to 320 K and report the standard thermodynamic properties of the tripeptide in the entire range. Thus, the heat capacity of APG was measured by adiabatic vacuum calorimetry in the above temperature range. The tripeptide exhibits a reversible first-order solid-to-solid phase transition characterized by strong thermal hysteresis. We report the standard thermodynamic characteristics of this transition and show that differential scanning calorimetry can reliably characterize the observed phase transition with <5 mg of the sample. Additionally, the standard entropy of formation from the elemental substances and the standard entropy of hypothetical reaction of synthesis from the amino acids at 298.15 K were calculated for the studied tripeptide.National Institute of Biomedical Imaging and Bioengineering (U.S.) (EB-003151)National Institute of Biomedical Imaging and Bioengineering (U.S.) (EB-001960)National Institute of Biomedical Imaging and Bioengineering (U.S.) (EB-002026

Thermodynamic Properties of the First-Generation Hybrid Dendrimer with &ldquo;Carbosilane Core/Phenylene Shell&rdquo; Structure

The molar heat capacity of the first-generation hybrid dendrimer with a &ldquo;carbosilane core/phenylene shell&rdquo; structure was measured for the first time in the temperature range T = 6&ndash;600 K using a precise adiabatic vacuum calorimeter and DSC. In the above temperature interval, the glass transition of the studied compound was observed, and its thermodynamic characteristics were determined. The standard thermodynamic functions (the enthalpy, the entropy, and the Gibbs energy) of the hybrid dendrimer were calculated over the range from T = 0 to 600 K using the experimentally determined heat capacity. The standard entropy of formation of the investigated dendrimer was evaluated at T = 298.15 K. The obtained thermodynamic properties of the studied hybrid dendrimer were compared and discussed with the literature data for some of the first-generation organosilicon and pyridylphenylene dendrimers

Preparation of Masters’ Students of Direction 15.04.06 “Mechatronics and Robotics” to Research and Development Activities

Сологубов Андрей Юрьевич, аспирант кафедры «Электрические станции, сети и системы электроснабжения», Южно-Уральский государственный университет, г. Челябинск, andrey.1993@ rambler.ru. A.Yu. Sologubov, [email protected] South Ural State University, Chelyabinsk, Russian Federationлистов в области мехатроники и робототехники, способных осуществлять профессиональное сопровождение научно-исследовательских и опытно-конструкторских разработок (НИиОКР), необходима грамотная реализация образовательной программы, раскрывающая структуру и последовательность связанных с конечными целями подготовки магистров к НИиОКР педагогических задач. В статье кратко раскрыта сущность НИиОКР в сфере мехатроники и робототехники, подразумевающая совокупность фундаментальных или прикладных поисковых, теоретических и экспериментальных работ, направленных на создание инновационных орудий труда с элементами искусственного интеллекта, организацию наукоёмких производств и развитие агрегатно-технологического комплекса в целом. Представлены трудовые функции магистранта в рамках НИиОКР, основные этапы НИиОКР, а также перечень профессиональных компетенций, которые должны быть сформированы в процессе обучения. Определены этапы содержания образования, на котором необходимо усваивание знаний и осваивание умений, и этап готовности выпускника к осуществлению трудовой деятельности. В статье представлен проект методического замысла как совокупность ряда решений и предложений, направленных на организацию подготовки магистрантов к НИиОКР. В качестве ориентира даны примеры тем НИиОКР, их цели и достигнутые результаты. Рассмотрены субъекты НИиОКР и требуемая квалификация. Даны рекомендации кафедрам, руководителям НИиОКР. Даны три ступени НИиОКР с окончанием в виде защиты дипломной работы, а также показано, на каком этапе и какие функции осваиваются. Предложена трёхступенчатая последовательная структура II этапа прохождения. Конечно, достижение результатов осложняется нестабильной экономической и образовательной ситуацией, а также нарушением бывших когда-то традиционными связей «технический вуз – производственная единица». Однако чёткое следование предложенным рекомендациям, совместные действия представителей структур вуза, технологической сферы и исполнителей НИиОКР, выраженные в представленном координационном графе, помогут преодолеть выявленные проблемы, а магистру в будущем быть максимально подготовленным и самостоятельным специалистом. For effective preparation of highly-qualified specialists in the field of mechatronics and robotics, capable of carrying out professional support for research and development (R & D), it is necessary to implement the education program that reveals the structure and sequence of pedagogical tasks related to the ultimate goals of preparing masters for research and development activities. The essence of R & D in the field of mechatronics and robotics aimed to create innovative tools with elements of artificial intelligence is given. The organization of science-intensive productions and the development of the aggregate-technological complex is briefly described. The labor functions of an undergraduate are presented in the framework of research and development correlated to the main stages of R & D, as well as a list of professional competencies that must be formed. The stages of education content interiorization are determined. They are mastering of knowledge; mastering of skills; forming of master’s student readiness to carry out professional activities. The main purpose of the research is to offer a set of solutions and proposals aimed to organize the preparation of graduates for research and development. The guidelines contain the examples of R & D topics, their goals and the results achieved. The required qualifications of R & D agents are examined. Recommendations to the departments and scientific advisors of R & D are given. Three stages of R & D are described that result in master’s thesis defense, and each stage is as-signed to the functions being performed. A three-step sequential structure of the second stage is proposed. The achievement of results is complicated by the unstable economic and educational situation, as well as by the violation of the traditional “technical university – production unit” ties. However, the strict adherence to the recommendations, the collaborative efforts of the repre-sentatives of the university, technology sector and R & D executors, expressed in the graph presented, will help to overcome the challenges, and to become the most prepared and independent specialist
