In the present study, the CUPID code was coupled with a system analysis code MARS and the coupled code was applied for the simulation of the PASCAL test facility [1], which is constructed to validate the cooling performance of the Passive Auxiliary Feedwater System (PAFS). The two-phase phenomena in the steam supply system including the condensation in the Passive Condensate Heat Exchanger (PCH...

This paper describes a technique to significantly improve upon the mass peak shape and mass resolution of spaceborne quadrupole mass spectrometers (QMSs) through higher order auxiliary excitation of the quadrupole field. Using a novel multiresonant tank circuit, additional frequency components can be used to drive modulating voltages on the quadrupole rods in a practical manner, suitable for bo...

A high temporal and spatial resolution emission inventory for the North Sea Baltic was compiled using current factors ship activity data. The includes seagoing vessels over 100 GT registered with International Maritime Organization traversing in Seas. bottom-up approach chosen compilation of inventory, which provides levels air pollutants CO2, NOx, SO2, PM2.5, CO, BC, Ash, NMVOC, POA, as well s...

Štúdium viazania stopových prvkov v sedimente vodnej nádrže Ružín Pre účely posúdenia možnosti využitia fyzikálnych a fyzikálno-chemických metód separácie, vybraná vzorka sedimentu z Ružína bola podrobené 5-stupňovej procedúre sekvenčnej extrakcie (SE) podľa Tessiera (Tessier et al., 1979) a Horowitza (Horowitz, 1991). Vo výluhoch bolo stanovované zastúpenie konštitučných (Fe, Mn, Ca a Mg) ako ...

The goal of this investigation is the thorough analysis and optimization a solar-assisted heat pump heating unit for covering space demand building in Athens, Greece. novelty studied system use high-temperature that can operate with radiative terminal units, leading to high thermal comfort standards. examined includes flat-plate solar collectors, an insulated storage tank, auxiliary electrical ...

Grounding facilities, including high-voltage DC grounding electrodes and auxiliary anodes in impressed current cathodic protection systems, inject into the ground. This study developed an experimental platform to determine safe limit of density for such facilities through analysis fish behavior on platform. Zebrafish (Brachydanio rerio) were selected experiment placed a tank; two rod used direc...

Thirty-five years ago, B.F. Skinner (1976) lamented a decreasing trend in the prevalence of cumulative records in the Journal of the Experimental Analysis of Behavior ( JEAB). The editorial began with the two memorable lines, ‘‘Evidently we have not long to wait for an issue of JEAB without a single cumulative record! I shall not miss the records so much as the kinds of experiments that could s...

Triboelektrostatická separácia minerálnej substancie zo slovenského uhlia V článku sú diskutované niektoré technické aspekty triboelektrostatickej separácie a výsledky aplikácie tohto postupu pri úprave troch typov uhlia, konkrétne energetického uhlia z Cígľa, Handlovej a Novák. Bolo zistené, že účinnosť separácie veľmi úzko závisí na druhu separovan uhlia. Prvé výsledky preukázali súvislosť me...
