Our time is characterized by the phenomenal acceleration of knowledge accumulation and the complication of its structure. Today information technologies are one of main ways to arrange and create effective tools for organizing the interaction and processing large amount of information. Nowadays academic institutions need to rely on special research, analysis of accumulated achievements and, on this basis, to develop forecasts, identify trends and prospects for the development of a scientific or other industry, and evaluate its potential. Today many information systems attempt to create methods and technologies of processing and saving information on the activities of scientists. The article provides a brief overview of rating systems for scientometric indices of universities. In our opinion, information of university’s scientific activity should be presented in the rating form, which gives an opportunity to analyze development in different directions and changes. The key idea of the article is presenting of our experience in developing system of automatic construction of ratings of scientific organizations based on their scientometric indicators in Scopus, Google Scholar and Web of Science. The main task of the system is automatic construction of consolidated rating of scientists, research groups, and organizations according to indicators of processed scientometric systems (Scopus, Google Scholar and Web of Science). These indicators are h-index, citations (numbers of total citations of documents that are indexed by the system), total number of scientist’s publications. The philosophy of the system is providing open data of different scientometric systems, and possibility to deploy our system in other organizations and customize it for individual goals and tasks.

While the natron and plant ash glass tesserae may be found on places of importance across the former Roman and Byzantine empires, wood ash glass tesserae are scarce. This is the first time a wood ash glass tessera is studied in detail. It was part of a magnificent 8-metres tall statue of Madonna in Malbork, Poland, created at the end of the 14th century and destroyed at the end of World War Two. It was found to be coloured by cobalt with possible impact of copper, and opacified by Ca-phosphate. Processes previously described in sodium-rich glasses were observed also in the studied potassium-rich wood ash glass tessera, such as diffusion of the respective alkali metal into the Ca-phosphate grains. The elemental composition of the tessera indicates that it is original - mediaeval, from the area north of Alps. Two phases were identified for the first time, to authors' best knowledge, in any glass tessera - leucite (tetragonal KAlSi 2 O 6 ) and pseudowollastonite (monoclinic CaSiO 3 ). As pseudowollastonite is a high-temperature phase, it may serve as an indicator of production temperature, which was further supported by the study of polymerisation index of model glasses. This study contributes to the knowledge of old technologies and showed that the know-how for opacification was imported from the Mediterranean, while the raw materials employed for the base glass preparation were from the area north of Alps., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.
