Analysis and efficiency of a gadolinium magnetocaloric material plate
Dorin Botoc, Ionut-Bogdan Rusu, Adrian Plesca, Jurij Avsec
Izvirni znanstveni članek
Oznake: gadolinium plate;magnetocaloric effect;magnetic flow;energetic efficiency;
In this article, the influence of a controlled magnetic field on gadolinium plates was modelled and simulated to be used in magnetic refrigeration installations. This is a state-of-the-art technology that does not use refrigerants and does not work based on vapour compression, which is based on the ...

Production of artificial cold for industry, based on the magnetocaloric effect
Dorin Botoc, Ionut-Bogdan Rusu, Adrian Plesca, Jurij Avsec
Izvirni znanstveni članek
Oznake: energy efficiency;magnetocaloric material;magnetic refrigeration;active magnetic regenerator;
The most common current technology for producing artificial cold is based on the operation of gas compression and absorption, which was discovered more than a century ago. This technology uses refrigerants as a heat transfer agent. Magnetic refrigeration is an innovative technology that works based ...

ǂThe ǂproperties of the material gadolinium and the working agent used in the installation of magnetic refrigeration devices
Dorin Botoc, Jurij Avsec, Adrian Plesca, Georgel Gabor, Rusu Ionut
Strokovni članek
Oznake: Gadolinium;heat transfer;magneto-calorific;magnetic field;
Much remains to be done to understand better and thus achieve better control over magnetic materials to maximize their magnetocaloric properties and performance, specifically for gadolinium. A clear path forward is highlighted by thorough experiments coupled with theory, in which the latter is teste ...

Modelling of magnetic regenerator and heat transfer agent in microchannels
Dorin Botoc, Bianca Eliza Oneata, Rusu Ionut, Alexandru Salceanu, Jurij Avsec
Izvirni znanstveni članek
Oznake: magnetic refrigeration;active magnetic regenerator;magnetocaloric material;
In this article, a brief introduction of conventional refrigeration is given, followed by a description and history of magnetic refrigeration. The active magnetic regenerator comprises 12 parallel plates of magnetocaloric material (gadolinium (Gd)), through which circulates the heat transfer fluid ( ...

Inverse curves
Alina Duta, Iulian Popescu, Ionut Daniel Geonea, Simona-Mariana Cretu, Ludmila Sass, Dragos - Laurentiu Popa
Izvirni znanstveni članek
Oznake: inversor mechanism;kinematic analysis;blocking positions;
The field of research considered in this work is that of mechanisms generating inverse curves. We were motivated to approach this field, proposing variants of mechanisms based on Artobolevsky’s inversor, in blocking conditions, due to the lack of recent applications related to inversor mechanisms th ...

Distribution, preparedness and management of Ukrainian adult refugees on dialysis—an international survey by the Renal Disaster Relief Task Force of the European Renal Association
Ewa Pawłowicz-Szlarska, Raymond Vanholder, Mehmet S. Sever, Serhan Tuğlular, Valerie Luyckx, Kai-Uwe Eckardt, Daniel Gallego, Dmytro Ivanov, Ionut Nistor, Rukshana Shroff, Andrej Škoberne
Izvirni znanstveni članek
Oznake: conflicts;dialysis;disasters;kidney patients;war;
Background. Due to the Russian–Ukrainian war, some of the about 10 000 adults requiring dialysis in Ukraine fled their country to continue dialysis abroad. To better understand the needs of conflict-affected dialysis patients, the Renal Disaster Relief Task Force of the European Renal Association co ...

A sustainable solution for the global construction industry can be partial substitution of Ordinary Portland Cement (OPC) by use of supplementary cementitious materials (SCMs) sourced from industrial end-of-life (EOL) products that contain calcareous, siliceous and aluminous materials. Candidate EOL ...
