Neutron and gamma dose rate calculations were carried out around horizontal beam tube no. 5 at the Jožef Stefan Institute (JSI) TRIGA Mark II research reactor. Results were compared to the experimental measurements in order to verify the computation model. In addition, another set of calculations and measurements was carried out, where an additional shield made out of concrete and paraffin was installed. With that configuration, we were able to study neutron and gamma scattering.

In this article we present a first part of the results obtained during an irradiation campaign conducted at the Jozef Stefan Institute to observe the behaviour of piezoelectric materials under gamma and neutron flux. Specific instrumentation has been developed and has enabled the monitoring throughout the irradiation of several materials such as lead zirconate titanate (PZT) or modified Bismuth Titanate (BiT) in either massive or thick film form. Various parameters such as resonance frequency, electromechanical coupling coefficient, electrical capacitance, dielectric losses were measured as a function of the flow and dose received. The results obtained confirm that the samples work up to doses of 10 18 n°/cm2 and that the behaviour of the samples varies according to their composition and form.

Introduction: The Jozef Stefan Institute developed a personal portable electrocardiogram (ECG) sensor Savvy that works with a smartphone, and this was used in our study. This study aimed to analyze the usefulness of telecardiology at the primary healthcare level using an ECG personal sensor. Methods: We included 400 patients with a history of suspected rhythm disturbance who visited their family physician at the Healthcare Center Ljubljana and Healthcare Center Murska Sobota from October 2016 to January 2018. Results: The study found that there was no statistically significant difference between the test and control groups in the number of present rhythm disorders and actions taken to treat patients with either observation or administration of a new drug. However, in the test group, there were significantly fewer patients being referred to a cardiologist than in the control group (p < 0.001). Discussion: The use of an ECG sensor helps family physicians to distinguish between patients who need to be referred to a cardiologist and those who can be treated by them. This method is useful for both physicians and patients because it shortens the time taken to start treatment, can be used during pandemics such as COVID-19, and reduces unnecessary cost.

SUMMARYThis is a concise survey of the activities carried out by the Robotics Laboratory of the “J. Stefan” Institute, University of E. Kardelj, Ljubljana (Yugoslavia) on the field of robotics research and development of robots. A list of research themes is given with a brief explanation of each containing the objectives, the obtained results, the history and the future outlook. Besides, the main projects concerned with the development of industrial robots are described, as well as the equipment which enables practical work and experimentations as a major element of the laboratory research and educational activities.

The project concerns the outgoing international mobility of block-release apprentices preparing the Master's degree in Instrumentation, Measurement, Metrology of the Filière Instrumentation (Physics Department of the Science Faculty). It targets universities and research centers involved in nuclear energy and is based on ongoing partnerships with CFA Epure–Méditerranée (apprenticeship center), EDF, and CEA thanks to on a solid research background in the LIMMEX laboratory run jointly by CEA and AMU (IM2NP) and dedicated to Instrumentation and Measurements under EXtreme conditions, on the ANIMMA international conference and the EFMMIN Franco-Moroccan school. This has led to the development of a useful network of operators (partners involved in the project) in priority geographical areas for AMU’s international strategy: Nuclear Reactor Laboratory at MIT, Moroccan Nuclear Center and Mohammed V University, Polish Nuclear Center, Slovenian Jožef Stefan Institute, Belgian Nuclear Center. The project will consist in sending a group of block-release apprentices for one week per year to a partner site who will propose visits to reactors, laboratories and companies, and participation in seminars, short courses, experimental projects and workshops together with local students. They will visit cultural places and prepare an activity report in English. When the project is completed its possible extension to other block-release courses at AMU will be examined because international mobility is a real advantage in terms of employability for young-people.
