Demand driven salt clean-up in a molten salt fast reactor – Defining a priority list

<div><p>The PUREX technology based on aqueous processes is currently the leading reprocessing technology in nuclear energy systems. It seems to be the most developed and established process for light water reactor fuel and the use of solid fuel. However, demand driven development of the nuclear system opens the way to liquid fuelled reactors, and disruptive technology development through the application of an integrated fuel cycle with a direct link to reactor operation. The possibilities of this new concept for innovative reprocessing technology development are analysed, the boundary conditions are discussed, and the economic as well as the neutron physical optimization parameters of the process are elucidated. Reactor physical knowledge of the influence of different elements on the neutron economy of the reactor is required. Using an innovative study approach, an element priority list for the salt clean-up is developed, which indicates that separation of Neodymium and Caesium is desirable, as they contribute almost 50% to the loss of criticality. Separating Zirconium and Samarium in addition from the fuel salt would remove nearly 80% of the loss of criticality due to fission products. The theoretical study is followed by a qualitative discussion of the different, demand driven optimization strategies which could satisfy the conflicting interests of sustainable reactor operation, efficient chemical processing for the salt clean-up, and the related economic as well as chemical engineering consequences. A new, innovative approach of balancing the throughput through salt processing based on a low number of separation process steps is developed. Next steps for the development of an economically viable salt clean-up process are identified.</p></div

Формирование и совершенствование оплаты труда на предприятии ООО «Томскнефтехим»

Объект исследования - предприятие ООО «Томскнефтехим». Предметом исследования является формирование оплаты труда на данном предприятии. Цель работы – исследование вопросов формирования и совершенствования оплаты труда на предприятии. В процессе исследования применялись научные и специальные методы экономических исследований, а именно диалектический метод, системный и процессный подходы, анализ литературных данных, обобщения, описания, расчетно – аналитический подход и сравнительно – сопоставительный методы. В качестве рекомендации предприятию в отношении экономических методов организации работы специалистов и руководителей и ее эффективности можно предложить ввести систему KPI (ключевых показателей эффективности) оценку способностей и качества работы персонала. Оценка результатов выступает основой для выплаты регулярных премий, то есть у сотрудников появляются возможности зарабатывать больше, а также оценка квалификации и потенциала работника может стать основой для принятия решений по его обучению, карьерному перемещению и эффективной работе на предприятии.The object of study - the enterprise of OOO "Tomskneftekhim". The subject of research is the formation of wage in the enterprise. The aim of this work is the study of questions of formation and improvement of labor payment at the enterprise. In the process of research used scientific and special methods of economic researches, namely the dialectical method, system and process approaches, the literary data analysis, generalization, description, analytical approach and comparative methods. As a recommendation to the enterprise in respect of economic methods of organization of work of specialists and managers and its effectiveness can introduce the KPI system (key performance indicators) the ability and quality of staff. Evaluation of results is the basis for the payment of regular premiums, then the employees have opportunities to earn more, as well as the qualification and potential of the employee can be the basis for decision-making in his training, career displacement and effective work at the enterprise

Structural Modification of the Natural Product Valerenic Acid Tunes RXR Homodimer Agonism

Retinoid X receptors (RXR) are ligand-sensing transcription factors with a unique role in nuclear receptor signaling as universal heterodimer partners. RXR modulation holds potential in cancer, neurodegeneration and metabolic diseases but adverse effects of RXR activation and lack of selective modulators prevent further exploration as therapeutic target. The natural product valerenic acid has been discovered as RXR agonist with unprecedented preference for RXR subtype and homodimer activation. To capture structural determinants of this activity profile and identify potential for optimization, we have studied effects of structural modification of the natural product on RXR modulation and identified an analogue with enhanced RXR homodimer agonism
