The production and release of fission products in fuel rods the primary coolant have been simulated by kinetic model during normal operation a pressurized water reactor. typical ratio I-131/I-133 has theoretically estimated at equilibrium conditions for intact fuels failure with small or large defects, respectively. radiochemical data loops gathered compiled from thirty-six cycles operating CPR...

The risks associated with unsteady two-phase flows in pressurized pipe systems must be considered both system design and operation. To this end, paper summarizes experimental tests numerical analyses that highlight key aspects of water pipelines. essential dynamics air–water interactions unvented lines are first considered, followed by a summary how change when air venting is provided. System b...

Compartment syndrome is caused by any condition which increases interstitial pressure within a muscle compartment to the extent that blood flow is compromised. It is seen classically after trauma to an extremity with crush injury, vascular damage or subsequent tight bandaging. Its sequelae may include irreversible neural and muscular damage secondary to the ischaemic insult. Previously describe...

This study demonstrates the applicability of pressurized stirred tank bioreactors for oxygen transfer enhancement in aerobic cultivation processes. The specific power input and the reactor pressure was employed as process variable. As model organism Escherichia coli, Arxula adeninivorans, Saccharomyces cerevisiae and Corynebacterium glutamicum were cultivated to high cell densities. By applying...

We recall the PFS (Pressurized and Free Surface) model constructed for the modeling of unsteady mixed flows in closed water pipes where transition points between the free surface and pressurized flow are treated as a free boundary associated to a discontinuity of the gradient of pressure. Then we present a numerical kinetic scheme for the computations of unsteady mixed flows in closed water pip...

Pressurized aerosols of sympathomimetic drugs are widely used in the treatment of bronchial asthma. The efficacy of this form of treatment is diminished in a number of patients by difficulties in coordination between the aerosol actuation and the inhalation. In order to improve the intrapulmonary deposition of terbutaline, an extension tube has been adapted to the regular pressurized aerosol de...

Two-stage pressurized anaerobic digestion is a promising technology. This technology integrates in one process biogas production with upgrading and pressure boosting for grid injection. To investigate whether the efficiency of this novel system could be further increased, a water scrubbing system was integrated into the methanogensis step. Therefore, six leach-bed reactors were used for hydroly...

In subduction zones, elevated pore fluid pressure, generally linked to metamorphic dehydration reactions, has a profound influence on the mechanical behavior of the plate interface and forearc crust through its control on effective stress. We use seismic noise-based monitoring to characterize seismic velocity variations following the 2012 Nicoya Peninsula, Costa Rica earthquake [M w (moment mag...

Time Projection Chambers (TPCs) operated at high pressure have become a topic of interest for future long baseline neutrino experiments. Pressurized gas retains the low momentum threshold particle detection atmospheric TPCs, but offers larger target mass interactions same volume. Operation poses several new challenges in safety aspects regarding overpressure and voltage safety. The presented Hi...
