The concept to high-level radioactive waste (HLW) repository generally involves anengineering-artificial barrier system, in which hardly compacted bentonite sand mixture blocks are placed carefully around the canister, and canister is of stiffness design. Placed sandmixture blocks, gradually receive hydration due groundwater. Thermal-hydraulic-mechanical-chemical phenomena after wetting, suctio...

The efficiency of the carbon dioxide absorption by soda lime was determined in the following way. (1) " Circle " breathing. In six experiments, a subject breathing through a Waters canister fully packed with 425 g of fresh soda lime was connected to a closed circuit spirometer as described by Erikson et al. (1951). The expired air then passed the canister before entering the spirometer where th...

Abstract The vitrification of radioactive waste within glass and subsequent disposal a geological facility (GDF) requires comprehensive understanding the effect dissolution on GDF performance. This paper aims to analyse both high-level intermediate-level (HLW ILW) source terms radionuclide release into geosphere just above vault (the ‘crown’). Radionuclide migration was simulated in GoldSim for...

Nondestructive evaluation methods play an important role in ensuring component integrity and safety many industries. Operator fatigue can a critical the reliability of such methods. This is for inspecting high value assets or with consequence failure, as aerospace nuclear components. Recent advances convolution neural networks support automate these inspection efforts. paper proposes using resi...

<p>Solar trackers are support platforms that keep photovoltaic panels facing the sun by following from dusk to dawn. There exist active solar make use of motors and gears orientate towards sun; passive operate through differential heating fluid in tracking rack follow sun. Passive suffer lack a night return mechanism slow wake-up response mornings due limitations on surface inclination an...

BACKGROUND Previous studies have shown poor compliance with regular drug therapy in children and adults with asthma. In preschool children the parents supervise and are responsible for drug administration, but little is known of compliance in this group. In addition, there are few data on the patterns of drug use of inhaled prophylactic asthma therapy or of the relation between compliance and s...
