Reaction class transition state theory: hydrogen abstraction reactions by hydrogen atoms as test cases

Journal ArticleWe present a new method called Reaction Class Transition State Theory (RC-TST) for estimating thermal rate constants of a large number of reactions in a class. This method is based on the transition state theory framework within the reaction class approach. Thermal rate constants of a given reaction in a class relative to those of its principal reaction can be efficiently predicted from only its differential barrier height and reaction energy. Such requirements are much less than what is needed by the conventional TST method

Intelligent CRM systems of transport companies

High technological efficiency and the use of intelligent systems are the main internal factors in the evolution of the transport company. Transportation companies are introducing digital infrastructure, trying to achieve practical results by focusing on customer demand, such as actively using Customer Relationship Management and holding on to the customer, increasing their loyalty. But there are problems in activating such systems because of their heterogeneity and non-systemic approach to their use. A system analysis is needed, which is the main purpose of this article. This problem is discussed in this article for highly competitive transport (logistics) business. The capabilities and impact of the transport company 's customer relationship management systems in the cloud are analyzed. The method of organization and regulation of business processes oriented to relations with clients, creation and development of cloud business infrastructure is proposed. The evolutionary cycle of the transport system in cloud infrastructure is described. A comprehensive multiplicative transportation efficiency model similar to the Allen model has been built and described how to use it to evaluate system self-regulation. The results of the work can become a methodological basis for solving practical problems of business processes of transport systems and their transfer to cloud infrastructure

QUANTITATIVE ANALYTICAL RESULTS ON TOPOGRAPHIC FEATURE OF THE VIETNAM’S CONTINENTAL SHELF WITHIN COORDINATES 11.7 - 14.00 AND 109.5 - 110.20

This paper presents some analytical results of bathymetry data according to three maps: Three dimensions (3D), slope, aspect on the continental slope and shelf area in the central part of Vietnam within the coordinates of 11.7 - 14.00 and 109.5 - 110.20. The obtained results have reflected clearly the geomorphic characteristics in this area. For example, on the 3D map, the continental slope exists three steps at the depths of 500 - 700 m, 1,250 m, and 1,500 - 1,700 m, running along the meridian 109.70, about 250 km long. These results are also shown on the slope and aspect map. On the slope map, from the depth of about 250 m to the first step base, the slope angle varies within 5 - 200 and from the first step base to second step base, the slope angle varies within 5 - 100; In the remaining part, the slope angle varies within 2 - 80. The other analytical results from the aspect map are also shown clearly, the aspect direction on the wall of three slope steps varies from 50 to 1000, reflecting the topographic slope towards the east, where is abyssal plain. The existence of Pliocene - Quaternary sediments along with steep continental slope caused landslide phenomenon in this area
