Study of Influence of Character Aromatic Bisphenol Oligoketones Based on Physical and Mechanical High Density Polyethylene

Researches on studying character of influence oligomers from diphenylolpropane on physic mechanical properties of polyethylene of high density are carried out. Optimum concentration oligo ketones in polyethylene of high density for stabilization of the basic physic mechanical properties is revealed at his repeated thermal processing.

Modified Asphalt Binder with Natural Zeolite for Warm Mix Asphalt

In recent years, warm mix asphalt (WMA) is becoming more and more used in the asphalt industry. WMA provide a whole range of benefits, whether economic, environmental and ecological. Lower energy consumption and less pollution is the most advantages of this asphalt mixture. The paper deals with the addition of natural zeolite into the sub base asphalt layers, which is the essential constituent in the construction of the road. Measurement is focused on basic physic – mechanical properties declared according to the catalog data sheets. The aim of this article is to demonstrate the ability of addition the natural zeolite into the all asphalt layers of asphalt pavement. All asphalt mixtures were compared with reference asphalt mixture, which was prepared in reference temperature.

LTC JOSEPHSON DEVICE TECHNOLOGY FOR LOW NOISE APPLICATIONS

Improved procedures to fabricate LTc superconducting devices based on high quality all refractive Nb/Nb junctions have been developed. Such reliable procedures have allowed the fabrication of Nb/AlOx/Nb structures and non-conventional light-sensitive junctions involving semiconducting tunneling barriers. Junctions and SQUID devices have been used in basic Physic investigations and in biomagnetic instrumentations.
