Application of mössbauer spectroscopy in the study of surface phenomena

Recently there has been a considerable growth of interest in the elementary processes occurring on the surface of a solid or associated with the effect of the surface on the properties of atoms and molecules within the bulk of the solid. Mössbauer spectroscopy yields unique information about the electronic structure and the nature of the motion of atoms and therefore the use of this method is extremely effective in fundamental investigations of surface phenomena. This review deals with the theoretical concepts of Mössbauer spectroscopy and the experimental data on its application in the physical chemistry of surface phenomena. A systematic account is given of new experimental results, which are compared with data obtained by other procedures. © IOP Publishing Ltd

Test of an LED Monitoring System for the PHOS Spectrometer

Preprint submitted to Elsevier Print on 26th January 2000A prototype monitoring system for the Photon Spectrometer (PHOS) of the ALICE experiment at LHC is described in detail. The prototype consists of Control and Master modules. The first one is 8x8 matrix of Light Emitting Diodes coupled with stable generators of current pulses. The system provides an individual control for each of the 64 channels of PHOS prototype based on lead-tungstate crystals. A long term stability of order of 10-3 has been achieved in integral beam tests of the monitoring system and PHOS prototypes

Distance learning: opportunities and challenges in quarantine.

The urgent introduction of distance education into the learning process due to the COVID-19 pandemic has become a spontaneous experiment, requiring urgent decisions, effective mechanisms to implement into the educational process and analysis of ongoing educational process. The possibilities of modern digital technologies made it possible to quickly set up the information component of education and to controle student’s knowledge. A detailed analysis of the communication between the faculty members of the department among themselves and analysis of the features of teaching and self-education of students in the field of medical radiology and oncology based on answers and comments with using Google classroom, Socrative, Messenger Telegram, etc. was made. Issues of communicative interaction between faculty members and students, psychological aspects of distance communication, language of instruction, logistics of distance education and methodological problems are described in details. It has been suggested that distance education may be equally effective for theoretical subjects in full-time study form, but when studying clinical disciplines, the priority should be given to traditional methods of teaching, involving student's bedside training. Taking into account technical possibilities and high risk of development of extreme and emergency situations, it is suggested to introduce permanent readiness for distance education, to create all – Ukrainian distance imitation service of patients’ follow-up. The importance of using the state language in training as the basis for mastering the professional Ukrainian and English language as the basis for mastering international medical experience is indicated
