The LubMedNet services for data storage and télédistribution

This paper is reports several Radiological and Oncological Information Systems integrated by a very efficient medical network system. The system covers the entire image flowpath in the Diagnostic Radiology Department (i.e. image acquisition, processing, archiving, long term storage) and allows for transmitting medical images through Municipal Area Network. The system has been working reliably since November 1999. About 22000 CT examinations have been archived using our system. Over 300 special examinations for radiotherapy planning have been sent to the Lublin Oncology Centre

Back to the Past? Social assistance and the coronavirus epidemic: preliminary analysis

The article intents to answer what conclusions drawn from the past experiences of the social assistance system may be useful for functioning of the system in the approaching economic crises produced by the coronavirus epidemic. Using comparative analysis, an attempt was made to compare selected elements of the social assistance system from the transformation period of the 1990s with the situation of social assistance in the last decade. Then, there are defined threats to the functioning of social assistance in case of the economic crisis

Powrót do przeszłości? Pomoc społeczna w obliczu epidemii koronawirusa: analiza wstępna

W artykule podjęto próbę odpowiedzi na pytanie badawcze o treści: jakie wnioski dla funkcjonowania pomocy społecznej w sytuacji nadchodzącego kryzysu ekonomicznego związanego z epidemią COVID-19 można wyciągnąć z przeszłości tej instytucji? Wykorzystując analizę porównawczą w postaci zestawienia wybranych elementów systemu pomocy społecznej doby transformacji systemowej lat 90. XX w. z sytuacją pomocy społecznej w ostatnich latach, określono możliwe zagrożenia dla funkcjonowania tej instytucji w momencie wystąpienia kryzysu gospodarczego

Fire Retardant Phase Change Materials—Recent Developments and Future Perspectives

The accumulation of thermal energy in the form of latent heat of phase transition using phase change materials (PCMs) is one of the most attractive and studied research areas with huge application potential in both passive and active technical systems. The largest and most important group of PCMs for low-temperature applications are organic PCMs, mainly paraffins, fatty acids, fatty alcohols, and polymers. One of the major disadvantages of organic PCMs is their flammability. In many applications such as building, battery thermal management, and protective insulations, the crucial task is to reduce the fire risk of flammable PCMs. In the last decade, numerous research works have been performed to reduce the flammability of organic PCMs, without losing their thermal performance. In this review, the main groups of flame retardants, PCMs flame retardation methods as well as examples of flame-retarded PCMs and their application areas were described
