The algorithm is proposed for determination of exponents parameters which approximate heat sink transient heat resistance as a function of time. It permits to include the heat sink into the system for calculation of power semiconductor structure temperatu... see more

First of all, it was necessary to replace flat products from high-alloy ??67???? and 06?15?6???? with one alloy that would possess the necessary set of physicomechanical characteristics. In the work, as a replacement for the used heat-resistant alloys, th... see more

Abstract. Problem  statement. Problematic  issues  in  the  field  of  friction  and  wear  occur  mainly  when used  in  extreme conditions of work parts. It increasingly meets the req... see more

DOI: 10.7764/RDLC.18.3.595Reinforced concrete elements with long curing ages tend not to present spalling when subjected to high temperatures since heat transfer in concrete is influenced mostly by the materials constituting its composition. Polypropylene... see more

The object of research is high-temperature thermal units – rotary kilns. Rotary kilns are used in various industries. The specified equipment has high energy consumption, which is due to the operating conditions of the kiln units in compliance with a numb... see more

Energy efficient technologies contributed substantially to reducing greenhouse gases emissions and contribute to economic growth. Lebanon is facing a serious problem in meeting the population’s excessive demand of electricity this fact urged consumers to ... see more

Physical characteristics of Svalbard reindeer (Rangifer tarandus platyrhynchus) fur samples were examined with respect to season. A total of 33 dorsal fur sections including adults and calves were investigated. A direct relationship between hair density a... see more

The present work numerically studies the thermal characteristics of a staggered double-layer microchannel heat sink (DLMCHS) with an offset between the upper layer of microchannels and lower layer of microchannels in the width direction, and investigates ... see more
