No full textHistCiteTM is a large-scale computer tool for mapping science. Its power of visualization combines
the production of historiographs on the basis of the analysis of co-citations of documents, with the
use of bibliometrics specific indicators. The objective of this article is, to present the advantages of
the new bibliometrics configuration of HistCiteTM (2004) when identifying articles to analyze the
histograms that produces HistCiteTM, in terms of cumulative advantage and aging of the citations
to do a comparative study of the results of HistCiteTM, in its indicators of amplitude and recognition.
Also is examined its treatment of the sampling problems, by formalizing the question of

ISSUE OF ESTABLISHMENT OF PERSONAL PENSIONS INSTITUTE IN THE USSR
No full textOne of the most important types of the Soviet pension was personal pension provision, which was intended for persons who contributed greatly to the construction of socialism and it was extremely prestigious. The article analyzes the pension case of ZinaidaVengerova, an employee of the People's Commissariat for Education of the Russian Federation and Ermioni Bervi-Flerov, the widow of Wilhelm Bervi-Flerov, the author of the widely acclaimed book “The Condition of the Working Class in Russia”. On the basis of the documents confirming their disability and harassment by the tsarist authorities, the author considers the first pension assignments deserved by Soviet citizens. The conclusion is that personal pensions of the most prominent public figures and their dependents in the conditions of the Civil war and the subsequent destruction arose as the reaction to their plight
Detector array for the H nucleus multi-neutron decay study
No full textSetup fitting the requirements for the detailed study of the five-body decay
of the 7H nucleus obtained as a result of the proton transfer from the 8He
projectiles to the deuterium target nuclei is being built at the radioactive
beam line of ACCULINNA-2 separator in the G.N. Flerov Laboratory of Nuclear
Reactions. Described here is the assembly of 100 BC-404 plastic scintillators,
intended for neutron detection, the annular Si detector telescope for the 3He
recoils, and the detector array providing the --TOF registration
of 3H nuclei emitted at the 7H decay. Results obtained by the Monte Carlo
simulations made for the energy values and flight passes of all these particles
are given together with the luminosity expected for the discussed experiments
