Cement-free binders for radioactive waste produced from blast-furnace slag using vortex layer activation technology
The paper addresses the issue of recycling granulated blast-furnace slag (gBFS) as a source for production of cement-free binder materials for further usage in rare-earth metals production for radioactive waste disposal. The use of the vortex layer activator was provided as main technique allowing to produce high-dispersed chemically activated binders. The paper examines the effect of processing conditions on the physical-chemical and mechanical properties of the resulting BFS-based cement-free materials and gBFS-based concretes

New approaches to assessment of researchers performance are of great importance to Russian science. In terms of intense flows of scientific information, design and application of new tools for information structuring, analysis and assessment have been increasingly demanded. Bibliometrics makes one of the most promising approaches. The authors generalize on the current status of bibliometrics, the range of its problems and point to its limitations.ΠΠΎΠ΄ΡΡΡΠΊΠ½ΡΡΠΎ ΠΎΡΠΎΠ±ΠΎΠ΅ Π·Π½Π°ΡΠ΅Π½ΠΈΠ΅ Π΄Π»Ρ ΡΠΎΡΡΠΈΠΉΡΠΊΠΎΠΉ Π½Π°ΡΠΊΠΈ ΡΠ°Π·ΡΠ°Π±ΠΎΡΠΊΠΈ Π½ΠΎΠ²ΡΡ

In the last five years the authors have studied applicability of citation analysis to the problem of detection of translated plagiarism. During these years we verified the efficiency of this method and carried out several applied studies. It enabled us to detect a number of illegal uses of borrowed foreign texts in several research areas. We showed that the method is more efficient in natural and exact sciences as compared to social sciences. Besides, it is more appropriate when analyzing research articles, reviews and reports as compared to other document types.Π ΡΠ΅ΡΠ΅Π½ΠΈΠ΅ ΠΏΠΎΡΠ»Π΅Π΄Π½ΠΈΡ

The authors attempt to determine publishing contribution of editorial board members (EBM) into the rating of their parent journals as exemplified by Russian journals in library and information sciences divided into low-, middle-, and top-rank groups. To determine this contribution, we studied EBM scholarly input to their parent journals vs. to other sources; besides, the scholarly input by EBM and other authors in each journal was compared. No correlation between the journal rank and share of EBMβs publications in their parent journals and/or EBMβs citations of their journal, or correlation between the journal rank and share of EBM papers in the respective journal were detected. However, the positive correlation was revealed between the journal rank and share of foreign EBM, regardless of their scholarly input in their parent journal. The analysis of citation of EBM papers in their journals, as well as the analyses of their journal citations provided by EBM in other sources, demonstrates significant impact of EBM on bibliometric indices of top- and low-rank journals implying active involvement of EBM in the development of their parent serials. The lowest or even negative impact of EBM on journal rank was identified among the middle-rank group of journals since their papers were poorly (if ever) cited. Thus, formal inclusion of experts into editorial boards of those journals and low interest they take in their journal may be assumed. Our findings contribute to scientometric studies of editorial boards and may be of interest to editors-in-chief and founders of journals.Π ΡΡΠ°ΡΡΠ΅ ΠΏΡΠ΅Π΄ΠΏΡΠΈΠ½ΡΡΠ° ΠΏΠΎΠΏΡΡΠΊΠ° ΠΎΠΏΡΠ΅Π΄Π΅Π»ΠΈΡΡ ΠΏΡΠ±Π»ΠΈΠΊΠ°ΡΠΈΠΎΠ½Π½ΡΠΉ Π²ΠΊΠ»Π°Π΄ ΡΠ΅Π΄Π°ΠΊΡΠΈΠΎΠ½Π½ΡΡ

Rare earth elements materials production from apatite ores
The paper deals with the study of processing apatite ores with nitric acid and extraction of the rare earth elements. The rare earth elements can be successfully separated and recovered by extraction from the nitrate- phosphate solution, being an tributyl phosphate as extraction agent. The developed scheme of the processing apatite concentrate provides obtaining rare earth concentrates with high qualitative characteristics
